12 Claims. (Cl. 118-3) The present invention relates to an improvement in printing presses and, more particularly, to an improvement in printing presses including means forapplymg adhesive spots to a sheet upon which an impression is being made when the sheet is removed from the chase. While the invention is preferably used with a bed and platen type or" printing press and is described in connection with the same, it will be appreciated that the invention is capable of use with othertypes of printing presses such as a cylinder type printing press, oflset type printing press, or the like.

Heretofore, in the manufacture of carbon-set forms, that is, forms wherein carbon paper is interleaved between printed forms and bound in pad or book form for use as invoices, sales slips and the like, it has been impractical and uneconomical for a small printer to print and bind such forms. The sequence used by small'printers in the past included, first printing the necessary material on the individual sheets and then after the sheets had been printed, theywere sent to the bindery where an operator few the printed sheets and carbon sheets, piece by piece, in sequence, to a machine by hand. Each time the sheets were fed to the machine, the operator had to'press his knee against a lever and apply a spot of glue to the sheet so that the carbon paper could be afi'ixed thereto. The books or pads were assembled in this step by step procedure, involving a considerable amount of time and labor, and thus resulted in high production costs.

' In large scale operation, such book or pad forms were made by printing the form on paper rolls. The paper rolls were then fed to another machine with anumber of carbon rolls, in proper sequence- The machine then glued the sheets together and individually cut the sheets to form sales books,'or the like. Such an operation necessitated having a largeprinting order to justify the high cost ofsetting up and maintaining the comprehensive equipment involved.

While themethod of making the books or pads by hand, that is, printing the individual sheets and then'interleaving the sheets with carbon paper and applying glue by hand, is costly as it requires an extensive amount of time to perform the complete operation, small printers who had small orders necessarily had to use this method of hand manifolding and gluing of the printed sheets and carbonpaper together. In other words, they could not alford to set up the elaborate equipment necessary to print on rolls of paper, then remove the rolls of paper from the printing presses and set up separate machines wherein the paper was interleaved with rolls of carbon paper out to size and glued. V

An object of the present invention is to provide a printing press means by which the adhesive necessary to'glue the books or pads together is applied when the sheets for the forms are printed. g

Another object of p the present invention is to provide a printing press with a chase which will apply spots of glue to a sheet as the impression is being made upon the sheet. "A still further object of the present invention is to i United States Patent 2,955,564 Patented'o 1960 2 provide a printing press wherein the chase is provided with means for applying glue to the sheet carried by the platen at the time the impression is being made, the press being also provided with means to cause the inking rollers to avoid contact with the adhesive applying means.

A still further object of the present invention is to provide a chase for a printing press which is held in a substantially vertical position when the sheet holding and impression means is making an impression on a sheet carried thereby, the chase being provided with means for applying adhesive spots to the sheet by a pumping action rather than a leaking action.

These and other objects of the present invention will appear more fully in the following specification, claims and drawings, in which:

Figure 1 is a diagrammatic view of the present invention utilized in a platen press, the inking rollers being shown in solid lines in a position for receiving ink from the inking plate and, in' broken lines, in a position just after applying ink to the type held by the chase.

Figure 2 discloses a fragmentary side view of the platen press showing the inking rollers just after applying ink to the type carried by the platen.

Figure 3 is an enlarged fragmentary view, partly in' tially. on the line 6-6 of Figure 5 and illustrating in addition a section of the platen opening the valve.

Figure 7 is a view taken on the line 7-7 of Figure 6, and V Figure 8 is an exploded view of a form book or pad showing. the interleaving of carbon papers between the printed sheets or forms, with the adhesivespots provided on the forms.

' Referring now to the accompanying drawings, the arrangement of the present invention is illustrated in association with a platen press of the type disclosed in United States Patents No. 2,088,377, issued July 27, 1937, to Kluge et al.; No. 2,3l8,165, issued May 4, 1943, to Kluge; and No. 2,429,874, issued October 28, 1947, to FrieL. i i

It will be understood that the aforementioned patents represent typical automatic platen presses, wherein the impression block or bed is adapted to receive and support a type-receiving case in a substantially vertical position, and a platen is adapted to receive a sheet while in a substantially horizontal position and transfer the sheet to a substantially vertical position, where the platen and bed are moved relative to one another to make an impression upon the sheet. Conventional means may be used for delivering the sheet from a stock magazine to the platen and for removing the sheet from the platen after an impression has been made and transferring the sheet to a suitable delivery box, where the sheets are deposited. Only those elements of the platen type printing press which are necessary for disclosure of the present invention are shown in the accompanying drawings, it being understood that the present invention is capable forapplication to any type of printing press, and especi ally those printing presses wherein at least the chase carrying bed is substantially in a vertical position when the sheet holding and impression means is in impression position.

printing press, generally indicated by the numeral 10,

The platen type printing press is provided with the usual stock magazine 12 having a sloping sheet receiving surface, wherein a pack 13 of blank sheets 14 of paper is supported on edge, by a rest 16. Rest '16 is intermittently advanced upwardly along the sloping surface so as to always present the foremost sheet of the pack at a predetermined or fixed sheet-receiving position. The foremost sheet 14 of the pack of sheets is picked off by a feeder arm 18 provided with the usual suction feed grips 20 and is deposited on a platen 22 of the press 19 when the platen is in a substantially horizontal position as shown, in broken lines, in Figure l. The sheet 14 is held on the platen 22 by the usual platen grippers (not shown) and the platen 22 is then moved in timed sequence, by suitable levers and cam mechanisms (not shown), in the direction of the arrow A to an impression position where the printing of the form on sheet occurs. As shown in Figure 6, the platen is substantially vertical and, when in this position, it is in what is known in the trade as the impression position with respect to a bed or impression block 24 which supports a chase, generally indicated at 26, and shown in broken lines in Figure 1. The bed 24 supporting the chase 26 may be stationary as it may be movable to the impression position as is clearly shown in th aforementioned patents.

After the impression is made on the sheet 14, the platen 22 is then moved back to its broken-line position of Figure 1, where the sheet 14 is picked up by suitable suction grippers (not shsown) and deposited on a delivery table 28, which is adjustable vrtically. The delivery table 28 is originally adjusted to an upper position but as sheets 14 are deposited thereon it may be automatically lowered to better receive the sheets.

The platen press of the present invention is provided with a pair of guide rails or tracks 30 which extend in parallel spaced relationship to each other along each side of an inking plate 32 and then vertically downwardly along each side of the impression block 24. Inking rollers 34, carried on saddle rods or frame members 36, are adapted to be moved across the inking plate 32 and downwardly along the rails or tracks 30 so as to apply ink to the type carried by the chase 26. As shown in Figure 1, the inking rollers 34 are moved by the frame members 36 through suitable links and earns (not shown) from the full line position where they are on the inking plate 32, to a dotted line position, where they are passing over the chase 26 and have applied ink to the type carried thereby. The action of the inking rollers 34 occurs when the platen 22 is out of impression position, as shown in Figure 1 and it will be understood that this relative movement is all in timed sequence. In the dotted line position of the inking rollers 34, it will be noted that they are just passing over the lower portion of the chase 26 and when they continued to follow the track 30 to a position where they are clear of the chase 26, the platen 22, shown in full lines, will be approaching the chase toward impression position, as is well known in the art.

As best shown in Figures 2 and 3, the inking rollers 34 are provided with trucks 38 which ride on the rails or tracks 30, the trucks being supported on the usual crossarms 40, which are pivotally connected, as indicated at 42, to a rod 44 carried in the frame member 36. A heavy coil spring 46, or the like, urges the trucks 38 into engagement with the track and permits the rollers to pass around the curve provided in the track.

As shown in Figures 1 and 4, cam means, such as the flange 48, is provided on the track or rail 30, adjacent the lower end of the vertical run, for the purpose of lifting the inking rollers outwardly of the chase, as will be described in more detail later in the specification. The flange 48 may be attached to the rail 30 in any suitable manner, such as by the machine screws 50.

Referring now to Figure 5, the chase 26 includes the usual rectangular frame having vertically spaced parallel 4 side walls 52 and horizontally spaced parallel side walls 54. The present invention includes providing the chase 26 with a glue fountain or adhesive reservoir 56 adjacent one of the vertical side walls 52, the reservoir 56 being either permanently afiixed to the side wall or detachably held in the side wall by the usual wedges or quoins 58 and 60, as well as the wooden spacer blocks 62, 64, 68

and 70. The type plate or type, is generally indicated at 72 and, of course, this is also held in place by the usual spacer blocks, wedges and quoins referred to above.

Also carried by the chase is a hollow manifold 74 which is square in cross-section and closed at one end, as shown in Figure 6, the manifold being held in horizontal position adjacent the lower horizontal side memher 54. Manifold 74 is provided with a port in fluid communication with the lower end of reservoir 56, by a tube or conduit 76.

As best shown in Figures 5 and 6, manifold 74 is adapted to carry a plurality of adhesive applicators, generally indicated at 78, for applying adhesive spots to the sheet carried by platen 22, when the platen is moved to impression position and then away from impression position. In more detail, the manifold 74 is provided with a plurality of threaded holes in which the applicators 78 are detachably received. The applicator 78 includes a nozzle 82 having exterior threads 84. Nozzle 82 has an interior bore 86, circular in cross-section and having a tapered valve seat 88. Nozzle 82 also is provided with a small bore in axial alignment with the bore 86.

Positioned in the bores 86 and 90 is a plunger element 92 having a portion 94 in the bore 86 square in crosssection, as shown in Figure 7. The plunger element 92 is provided with a stem 96 having a diameter slightly less than the diameter of the bore 90. Stem 96 extends through the bore 90 and is adapted to project out of the end 98 of the nozzle, when the plunger is moved to the right of the position shown in Figure 6. A tapered surface, 160 complementary in shape to the tapered surface 88 is provided intermediate the stem 96 and the square portion 94 of the plunger. When the plunger is moved to the right of Figure 6 the tapered surface 100 of the plunger engages the tapered surface 88 of the nozzle and prevents fluid from within the manifold flowing through the space between the wall of bore 90 and the stem 96.

The rear end 0f the plunger element 94 is provided with a projection or peg 102 which is adapted to receive one end of a coil compression spring 104. The other end of the spring 104 abuts against the rear interior surface of manifold 74 and thus, the spring constantly urges the plunger member 92 toward a closed position.

Referring now to Figures 1 and 4 it will be noted that, when the chase 26 is held in position on the bed or impression block 24, the nozzles 82 extend horizontally of the chase, in a position substantially adjacent to the position where the flanges or earns 48 are positioned on the tracks or rails 30. The reason for providing the flanges 48 in this position is so that when the inking rollers 34 are moving across the chase to ink the type carried therein, and come to the area where the applicators 78 are positioned, the rollers 34 are raised out of engagement so that they will not hit the ends of the stems 96 which extend out of the nozzles. Thus, no ink is applied to the ends of the nozzle nor is any glue or adhesive which may happen to be on the ends of the nozzles, applied to the inking rollers.

In the application of a spot of glue to one of the sheets 14, it will be noted that the sheet 14 is in substantially a vertical position. By providing the reservoir 56 in a vertical position with respect to and above the manifold 74, the interior of the manifold is completely filled with the adhesive. The particular design of plunger and nozzle arrangement, as heretofore described, provides for a positive application of a spot of adhesive, rather than application of a spotof adhesive by leakage. In other words, when the platen 22 advances the sheet 14 90 onto the sheet 14.

forward toward the chase, the sheet 14 will engage the stem 96, urging the plunger 92 to the position shown in Figure 6. Since the portion of the plunger. 94, in the bore .86, is square, adhesive from the manifold 74. can pass about the plunger into thearea between the valve seat 88 and the tapered surface 100. When the platen 22 is retracted away from the chase, carrying with it the sheet. 14, the plunger 92 is urged to the right of Figure 6 by the spring 104. This causes the adhesive between the surfaces 88 and 100 tobe pumped through the bore In eflect, the particular adhesive applicator'82, disclosed, provides a measured amount of adhesive for each spot.

By making the applicators 82 detachably held in the manifold 74, greater adaptability of the invention is obtained, in that, if the number of spots of adhesiveneed be changed, certain applicators may be removed and replaced by a plug.

.The reservoir 56 may be easily filled with adhesive by removing a plug' 106 provided at its upper end. This provides a convenient means of refilling the reservoir while the chase is positioned on the bed 24.

Referring now to Figure 8 of the drawings, the view showntherein represents the manifolding of a pad by the interleaving of carbon paper between the printed form sheets 14, having the glue spots along one of their edges. In more detail, a first form sheet 14 is printed and simultaneously the spots 108 of glue are applied when the sheet and the platen are removed from impression position. The sheet is then removed from the platen, in a known manner, and placed on the delivery table 28. A piece of carbon paper 109, substantially the same size and having pre-punched apertures 110 in one edge, is then placed on top of the sheet 14. The apertures 110 are spaced apart a distance substantially equal to the adhesive spots on the sheet 14 so that the glue will extend through the apertures. When the next form sheet 14 is printed and the glue spots are applied, it is permitted to be placed on the delivery table 28 on top of the carbon paper. Since the undersurface of the form sheet does not have an adhesive on it the adhesive extending up through the holes in the carbon paper, attaches the sheet thereto with the carbon paper 109 secured therebetween. This process is succesively repeated until a desired number of form sheets 14 and interleaved carbon sheets 109 is provided.

A stack of cover sheets 14 may be preliminarily run through the press with the adhesive applicators blocked ofi, so that no glue is applied thereto. These sheets may be placed in a pile conveniently near the delivery table and may be assembled on the sets, as the top sheet in the set, so that there are no adhesive spots visible. Each of the sheets 14, may be provided with suitable perforated lines 112 made by a perforating rule held in the chase, as is conventional. By providing the perforated lines, the form sheets and carbon paper may be separated, as desired.

As shown in Figure 5, the type form is set up to simultaneously print two forms in side by side relationship, on a single sheet of paper 14. The books or pads are assembled, as heretofore described and, after they are assembled, the pads are cut down the middle to form two pads of forms, such as sales slips, invoices or the like.

Having set forth the nature, objects and advantages of the invention, it will also be obvious that the invention is susceptible to some changes and modifications, without departing from the principle and spirit thereof. For this reason, the terminology used in the specification is merely for the purpose of description and not limitation, the scope of the invention being defined in the appended claims.
