JOHN F. MCNUTT, OF WARREN, OHIO, ASSIGNOR TO THE HARRIS AUTOMATIC PRESS COMPANY, OF NILES, OI-IIO.
FEEDER FOR PRlNTlNGwPRESSES.
SPECIFICATION forming part of Letters Patent No. 678,754, dated July 16, 1901.
Application filed July 25, 1900.
To @ZZ whom, it may concern,.-
Be it known that I,.IOHN F.MCNUTT,of Varren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Feeders for Printing Presses; andIdohereby declare the followingl to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to feeders for printing-presses.
The object is to provide means for automatically feeding sacks or sack-tubes from a pile thereof.
Paper sacks are usually printed before their make-upis completed-thatis,wl1en the tubes are printed the bottoms have not then been formed. These tubes when piled or stacked one upon another preparatory to the printing are flattened, thereby forming inner and outer longitudinal edges or creases.
My invention contemplates the employment of means for engaging and moving forward one end of asack and means for engaging the sack at another point for moving forward the other end thereof. It also contemplates the employment of means for opening the sack at one end-that is, holding the sides thereof apart for the admission of one feeder-and also the employment of means for effecting a side register of each sack as it is being positioned by the feeders.
The invention will be hereinafter fully set forth, and particularly pointed out in the claims.
In the accompanying drawings, Figure l is a View in perspective showing my improved feeding mechanism applied to a printingpress, portions only of the latter being indicated. Fig. 2 is an enlarged front elevation with parts broken away, showing the opener extended into the topmost sack-tube. Figs. 3, 4, and 5 are diagrammatical plan views showing various positions of the parts. Fig. 6 is an enlarged plan view of the feeder which first acts on each sack. Fig. -7 is an enlarged side view of the second-acting feeder. Fig. 8 is an enlarged view of the sack-opener.
Serial No. 24,781. (No model.)
Fig. 9 is an enlarged edge view of the sideregistering device and the feed-rolls. Figs. 10 and 11 are enlarged details.
Referring to the drawings, l designates the frame of a printing-press, a portion only of which is indicated.
2 is the hopper, in which the sack-tubes are piled fiat one upon another, the pile being held in proper position by suitable means. When thus piled, the sacks are creased longitudinally, and the tops are placed at the right, While the ends from which the bottoms are subsequently formed are at the left, as shown in Fig. l.
3 is a bed extending across the frame about on line of the passage of the stock to the press-cylinders,'and through it project the lower feed-rolls et, with which coact the upper feed-rolls 5.
6 is the sack-opener. It comprises a horizontally-disposed arm 7, formed near one end with an upwardly-extended portion 8, which is bent to terminate in a downwardly-inclined extension 9, and also a flat plate 10, through a loop 1l of which the arm 'Z is eX- tended. This plate is formed at one end with a finger 12 and at its other end is pivotally connected to a stationary bracket 13, suitably secured to bearing l5 of a shaft 14E,which bearing is supported by a casting fast on cross-rod 16 of the press-frame. The plate lO is normally held firmly down on the pile of sacks by a coil-spring 17, encircling a pin 18, hung from bracket 13. Thearm 7 is secured to the lower end of a post 19, depending from a crank-arm 20, fast on shaft 14. A second crank-arm 2l of this shaft is connected by a link 22 to an arm 23 of ashaft 24,which latter shaft is operated by any suitable means capable of imparting thereto a back-and-forth partial rotation. This partial rotation being communicated to shaft 14 will impart a backand-forth movement to arm 7 of the opener, the loop 11 of plate 10 retaining the arm in proper position. As these movements occur the downwardly-inclined extension 9 will enter between the two sides of the topmost sack-tube, and the finger 12, bearing upon the other side of the tube, retains it in position as the opener-arm travels inward. In
this way the two sides of the sack-tube are separated and held apart.
25 is a feeder which enters the end of the sack-tube subsequent to the entrance of the opener. It is shown as being composed of`a curved plate pivoted near one end to the outer end of an arm 26, fast on a shaft 27, whose beveled pinion 28 is driven by a toothed segment 29 on a shaft 30, which latter is designed to be partially rotated by suitable means connected to one end thereof. To one end of the feeder 25 is loosely secured a rod 3l, which is pivoted at its other end to arm 26. A spring 32, encircling this rod, holds the feeder normally against a shoulder 33 of arm 26. To this feeder, near its pivotal connection to arm 26,is secured one end of a rod 34, which is passed through and guided by a side extension of said arm and at its inner end carries a roller 35, which in the partial rotation of shaft 27 will contact with a stop 36, projecting from the bed 3. When the roller of rod 34 thus engages with the stop 36, the feeder is thrown out of the arc of movement on which it had traveled, as shown in dotted lines, Fig. 6, such forced movement of the feeder being against the tension of its spring 32. As the feeder engages the forward 1ongitudinal side crease or edge of the sack-tube, the latter will be partially fed forward at one end against one of two stops 37. A roller 38 on one of the uprights of the hopper bears upon the outer left-hand corner of the pile of sacks. This serves to retain the topmost sack while the feeder 25 is in action, the movement of the latter not being sufficient to overcome the friction of roller 38.
39 is a second feeder for act-ing upon the sack-tubes after they have been moved forward by the feeder 25. lt is shown in the form of an arm 40, having a hook 41 on its under side, at its lower end, and connected at its upper end by a universal joint 42 to a lever 43, fulcrumed on a bracket 44, mounted on cross-rod 16. The upper end of this lever is connected by a link 45 to an arm 46 of shaft 24. The universaljoint 42 has a tubular portion 46', through which the pivot-pin of arm 40 is passed. This tubular portion is swiveled to a link 47, which in turn is pivoted to lever 43. A spring-arm 48 serves to maintain the tubular portion 46 in the proper position and yet allow it to have a limited axial movement in one direction, its movement in the opposite direction being prevented by a stop 49, depending from link 47. (See Fig. 1l.) As the shaft 24 is moved rearward the lower outer end of the feeder-arm 40 is thrown out on a plate 50, which overhangs the pile of sacks, being suitably secured at 51 to a cross-rod of the hopper. As the movement of shaft 24 is reversed the hook 41 contacts A with a ridge or-iiange 52, extended diagonally the hook frees the plate 50 it engages the outer longitudinal edge of the sack-tube, which has been previously partially moved forward by the feeder 25. (See Fig. 4.) The further rotation of shaft 24 will cause the feeder 39 to feed the sack tube forward against the other of the stops 37, the feederarm having assumed its proper position under the action of spring 48, thus causing the forward edge of the sack to register against the said stops. (See Fig. 5.)
53 is a side-registering device, the movement of which is timed so that it will engage the top end of each sack-tube as the latter is being moved forward by the feeder 39. It is shown in the form of a curved plate 54 on the lower end of a lever 55, fulcrumed on an arm 56, extending from a ring 57, fast on-cross-rod 16. At its upper end this lever is bent at right angles in line to be struck by an arm 58, fast on shaft 24. A spring 59 serves to hold the lever in its normal position. The curved 'plate 54 has a horizontal portion 60, which overhangs the bed 3, a downwardly bent ange 61 (see Fig. 10) bearing on such bed, so as to engage the top edges of the sacktube and effect the side register thereof. This flange is curved and elongated at 62 tofit the front curvature of the bed and act as a guide to maintain the registering device in proper position when the arm 58 acts on lever 55 and swings the plate inward to move the sacktube longitudinally.
In practice the sack tubes are piled or stacked in the hopper, any suitable means being employed for maintaining an approximately uniform top level. The roller 38 is caused to bear on the top of the pile, holding the sack-tubes at one corner. Motion being imparted to shaft 14 from shaft 24, the opener separates the two sides of the topmost sacktube, (see Figs. 1 and 2,) and the shaft 27 being operated by shaft 30 the feeder 25 swinging axially enters the open end of the sack, and as it engages the forward crease of the latter it is thrown out of the arc of its initial movement by rod 34 engaging stop 36, thus pushing the sack forward and obliquely against the adjacent stop 37. (See Fig. 4.) The feeder 39 having been thrown outward on plate 50 by the rearward rotation of shaft 24 it is, as the rotation of said shaft is reversed, drawn obliquely over said plate, and upon getting clear thereof its hook engages the outer longitudinal edge of the sack-tube and its further movement in bringing the sack into proper position causes the forward longitudinal edge of such sack to register squarely with both of the stops 37. As this action of the feeder 39 is taking place the side registering device engages the top end of the sack-tube and moves the latter longitudinally. The tube being thus properly positioned is taken up by the feed-rolls and fed to the press-cylinders.
