IMPROVEMENT IN PAPER-BAG MACHINES:

Specification forming part of Letters Patent No. 84,076, dated November 17, 1868; Reissue No. 1.876- dated September 11, 1877; application filed June 16, 1871.

- taken through the'center of the machine.

This invention consists in the general arrangement of the elements of the machine for the purpose of making paper bags with great facility and speed.

To enable others skilled in the art to make and'use this invention, its construction. and operation will now be described.

A marks the side frames, made of suitable material, preferably metal, and tied together by brace-rods X, in which side frames all the shafts and rollers have their bearings.

B is the, shaft or spindle on which the web of paper to be made into bags is rolled. This web of paper is carried over the roller O,passing between it and the paste-box D. This paste-box D is fastened to one side of frame A,

and supports within it a shaft, 1, carrying a pasting-wheel, 2, fastened on it, which shaft is turned by a band, 3, running around the pulleys 4 and 5, on the ends of the shafts G and 1, motion being imparted from the roller 0 as it is revolved by the movement of the paper web as it is carried forward. The pasting-wheel 2 bears upon, and in this manner dis 'b toe the paste on, the edge of the web of pa 7 'r. This pasting-wheel L: is held upon the shaft 1 by a set-screw, and it may be moved' to any point on said shaft, according to the width of the web and the size of bags to be made. The web of paper,with its edge pasted,ispassed between the rollers E and F. The roller F is a short one, fixed at a central point upon-the shaft 6, and rides loosely upon the 'roller E, which is driven by the toothed wheel 49, which, through an intermediate wheel, 47, receives motion from a gear, 46, on the main shaft 9. These rollers carry the paper forward over theknife G, which issupported in a slightly-inclined plane, and is reciprocated in slots 7 in the side frames by a camwheel, 8, on' the main drivingshaft J, which ,wheel lifts the lever 10, fastened to the rockshaft 11. The knife G is attached to this rockshaft by means of the jointed levers l2 13, so that, when the lever 10 is lifted or raised by the cam-wheel .8, the knife will move backward in the slots 7. The spiral spring 14, fastened to the under side of the lever 10 and to one side frame, causes the parts to react, and the 'knife G to move forward again into its proper place. This knife G has its cuttingedge formed of serrated teeth, and its central portion eztended a -considerabie distance beyond' its ends. (See Fig. 1.) This extended central portion is of a length equal to the width of the bag to be formed from the web it severe. The cutting-knife H also has an an edge composed of serrated teeth, and its ends protrude a proper distance to adapt it to conform to the shape of, and'therefore lit, the knife G. This cutting-knife H is fastened to collars l I on the shaft 15, which is revolving, and the paper web is severed by this knife sweeping by the'edge of the knife G, upon which the said web is supported. When thus severed the forward end of the web has its central portion of a length equal to the width of the bag to be made, protruding as a lip a distance sufiicient to ultimately form the bottom seam of the bag.

As soon as the knife H has swept past the knife G, the latter recedes, as hereinbefore described, and the spring forwarders J J, which are fastened to the collars I I, press the paper, now out for the size of bag required, upon a slidingplate, 16, which devices, together, carry it forward till the edge of the paper is delivered under the forward end of the former K, and upon two endless rubber carriers or belts, 17 which run around the roller 18 fast on the shaft 19, and a roller, 20, fast upona shaft, 21, at the other end of the former K. On the end of this shaft 19 is a pulley, 22, which, by means of a band around the same,

drives or turns thepulley 23 on the shaft 21, thus driving the endless rubber carriers or belts carrying the paper bag forward under the former K. I

The former K is aflat plate of a width equal. to that of the bags to be formed, and is sus-- pended by a bridge formed of brackets 60,

. cross-bars 61, and upright brace 62.

the pasted edge of the paper from dropping downand adhering to the other edge of the paper before it is desired to have it do so, there is a holder, 27, fastened upon the former K, which sustains the pasted edge until the opposite edge of the paper is completely folded dqwii onto the former by the folder 26, when the two edges are allowed tomeet and-be joined to form the bag-tube.

28 represents one. 'two, or more 'rollcrs,

which serve to hold up the rubber carriers against the bottom of the former K, and in sure the carrying forward of the. bag. They have flanges upon them at proper distances apart to hold-1 the rubber carriers at any distance from e'dch other that' may be required, so that when the bag-tubes arrive at the roller 20 there will be a spacebetween the carriers to allow the short roller 30, fastened onto the shaft 31, to press thepastcd edge down to form the hag-tube seam.

The bag'tubc thus formed and pasted together has one side of its bottom (the lower) longer than the other, formed by the uneven cut, made, as beforedescrined, by the arrangement of the teeth of the knives G and H, and.

when the 'bag-tube-has passed between the rollers 20 and 30, this lower end or lip willextend andprotrude through the slot cut through the apex of the angularly-bent guideplate 32. The bag passes through this slot, and while its lower or bottom end or lip is protruding through it, said end or li'p is pasted by the pasting-roller 33 the folder 34 then descends and doubles the bag-tube upon a line considerably behind the outer edge of-the pasted lip, this operation forcing the bag-tube on the line of doubling between the cylinders or rollers In passing between these the lip is pressed down on and united to the body of the tube, thus forming a bag, which drops down underneath the machine. These rollers 35 are geared together, and are turned by from a larger roller, L, which runs in a pastearonnd the pulley 39 on the shaft 21.

The pasting-roller 33and thefolder 34 ar reciprocated perpendicularly in grooves in the side frames by means of the bell-cranks 40, on the rock-shafts 41, and the arms or rods 42, which are attached to levers 43, near the main driving shaft 9, sothat when this latter is turned cam-wheels 44 Willpress the lovers 43"lorward with the. rods or arms 42, which then turn the bell-cranks 40,-so that'the folder and pasting-roller are moved downward, and the spiral springs 45, attached to levers 43, bring them back, thus allowing the folder and pasting-roller to again move up.

. The machine is operated by means of a .crank,M,on the main or driving shaft 9,.which turns the toothed wheel 46, and, by means of gear-wheels 47, 48, 49, 50, turns the roller E and the shaft 19, with its roller 18. At the other end of the main shaft 9 is a dogged which the collars I I, cutting knife H, and spring-'fowarders J J are fastened.

and having passed between the rollers 35, to drop down underneath, they may be madeto come out at the end of the machine, by means of bands passing around a rolleryN, on the shaft 53', and beneath the rollers 35, to and around another shaft, 54, with a similar roller, 0, under or beneath the forward end of the former K, and this shaft 54 may be operated upon bya pulley, 55,011 the same, and a pulley, '56, on the extended shaft of one of the rollers 35.

46 on the main shaft can be changed toeither a larger or smaller wheel,and the gear-wheels 47 48 brought closer or farther apart, as they are'fa-stened in slots in the side frame. For the same purpose the knives G and H must also be changed. v

The folders '26 can be moved either out or in, to suit the former K, which must be changed according to the width of the bag required.

A movable guard may be employed on 1 the revolving knife H to press the paper down beneath the are of its motion, in order that the knife may pass without interferingwith the paper in its passage. v Having thus fully described the invention, what is claimed ise 3 1.
