EDWIN J. I-IOVLETT, OF PHILADELPHIA, PENNSYISVANIA, ASSIGNOR TO THE UNION PAPER BAG MACHINE COMPANY,
OF SAME PLACE.
MACHINE FOR FOLDING SIDES OF SATCHEL-BOTTONIED BAGS.
SPECIFICATION forming part of Letters Patent No. 643,821, dated February 20, 1900.
Application tiled March 29, 1898.
To all whom it may concern:
Be it known that I, EDWIN J. HowLErT, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Machines for Folding in the Sides of Satchel- Bottomed Paper Bags, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.
My invention relates to the construction of a machine adapted not to make paper bags, but to fold in the sides of Satchel-bottomed bags, so as to give them for package and shipment a rectangular shape and so also that the bag will open out for use with greater` freedom and more regularity than is the case with similar bags not folded in the same way.
The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in which- Figure 1 is a plan view of a machine embodying my invention; Fig. 2, a sideelevation thereof, taken as on the section-line 1 1 of Fig. 2; and Fig. 3, a rear elevation of one of the creasing devices.
Aindicates the frame of the machine, and A A cross-bars resting on top of the portion A and serving to directly support the operative mechanism.
A2 A2, dac., indicate housings supported on the frame A at its corners and in which the shafts of the machine are journaled.
Supported on the cross-bars A are the baseplates B B, over which the bags being operated upon travel and which have a space between them at the center of the machine for the feeding devices to move in. Y
, C and C' and O2 and O3 are shafts arranged in pairs in the housings A2 at the front and back of the machine, the shaft O being provided with a driving-wheelD,as shown. A sprocketwheel D' and a spur-wheel D4, the last-mentioned spur-wheel meshing with a similar one on the shaft C and the sprocket-wheel D' communicating motion through a chain Ds to Serial No. 675,578. (No model.)
a similar sprocket-wheel D2 on the shaft C2, which, through a gear-wheel Dand a similar Wheel on the shaft C2, drives the last-men* tioned shaft.
E E E2 E3 are drums or pulleys secured on the center of the four shafts and serving to support and drive the belts E4 and E5, between which-the bags move and by means of which they are fed along through the machine. On the shaft C are creasers F F, operating in connection with elastic-faced rolls F F4 (indicated in Fig. 3) and so that as the bag is passed between the creasers and rolls it is by their action creased, as indicated in the drawings-that is, from points coincident with the 'corners of the bottom along lines parallel with the sides of the lateral edges.
G is a cross-bar supported on the plates B B and, as shown, provided with slots G'. p H H are light straight-edged metal plates secured to the cross-bar G through studs H' and nuts H2, the slots G' permitting the adjustment of the position of the plates. In order to brace the plates, I have, as shown, provided them with threaded upright standards H2 H2, connected by means of a right and left threaded adjusting-screw H4, aording a means for adjusting said plates toward and from each other and maintaining them in parallelism. It will be understood that the plates H H could be adjusted so thattheir outer edges will correspond and register with the creases formed by the creasers F F, the bag passing from the creasers below the plates H, with its lateral edges projecting beyond the outer edges of said creases.
I I indicate folding-plates adjustably sea cured to the plates B B conveniently, as indicated, by means of slotted extensions I' I2, the shape of the folding-plates being such as to turn the edges of the creased bag irst upward and then inward and downward over 9o the edges of the plates H and down upon the face of the bag.
The object of the machine and the result of its operation are indicated in Fig. 1. J, at
the right-hand end of the machine, indicates an ordinary Satchel-bottomed bag being fed into the machine and creased on the lines J J, while at the left-hand end of the drawing a bag J is represen ted as being delivered from the machine with the lateral edges folded in upon the face of the bag upon the lines J Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. A machine for folding over the sides of Satchel-bottomed paper bags having in combination with means for Vfeeding the bags through the machine, adjustable creasers as F F', F F for creasing the bags on the lines of the folds desired, plates as H H lying along and parallel to the line of the crease adjustably secured to the frame of the machine and serving as straight-edges over which the folds are made, means for adjusting said plates toward and from each other and for maintaining them in parallelism, and stationary means for turning the outer edges of the bag over upon the body thereof on the lines of the creases as the bag is fed through the machine, substantially as specified.
2. A machine for folding over the sides of Satchel-bottomed paper bags having in combination the belts E4 and E5 for feeding bags through the machine, adjustable creasers as F F', F F' for creasing the bags on the lines of the folds desired, plates as H H lying along and parallel to the line of the crease adjustably secured to the frame of the machine and serving as straight-ed ges over which the folds are made, means for adjusting said plates toward and from each other and for maintaining them in parallelism, and stationarymeans adjustable toward and from the plates for turning the outer edges of the bag over upon the body thereof on the lines of the creases 1 as the bag is fed through the machine, sub- 4o stantially as specified.
3. A machine for folding over the sides of Satchel-bottomed paper bags having in combination with means for feeding the bags through the machine, adjustable creasers as F F', F F for creasing the bags on the lines of the folds desired, plates as H H lying along and parallel to the line of the crease and serving as straight-edges over Which the folds are made, said plates being adjustably secured to the frame of the machine at one end and provided with means intermediate their ends for adjusting them toward and from each other and maintaining them in parallelism, and the folding-plates I I for turning the edges of the bag over the plates II H and down upon the4 center of the bag as the bag is fed through the machine.
i. A machine for folding over the sides of Satchel-bottomed paper bags, having in combination with means for feeding the bags through the machine, adjustable creasers as F F' F F for creasing the bags on the lines of the folds desired, plates H H lying along and parallel to the lines of the longitudinal creases and serving as straight-edges over Which the folds are made said plates being adjustably secured to the frame of the machine, and provided with means for adjusting them toward and from each other and maintaining them in parallelism, and stationary curved plates I I for turning the outer edges of the bag over upon the body thereof as the bag is fed through the machine.
