CLARENCE A. CHANDLER, OF EAST BRIDGEWATER, MASSACHUSETTS.
PAPER-BAG MACHINE.
SPECIFICATION forming part of Letters Patent No. 251,997, dated January 3, 1882. Application filed October 17, 1881. (No model.)
To all whom it may concern Be it known that I, CLARENCE A. CHAND- LER, of East Bridgewater, county of Plymouth, State of Massachusetts, have invented an Improvement in Paper-Bag Machines, of which the followingdescription, in connection with the accompanying drawings, is a S[)0( ification.
This invention in paper-bag machines relates to mechanism for cutting a lip in one ply of the tube,'the said lip facilitating opening the bag.
My present invention is an improvement on the machine represented in my application No. 25,019, tiled in the United States Patent Office January 31,1881, to which reference may be had.
In this my invention the lip-cutter, which is herein shown as made to cut through the upper ply of the tube, is loosely pivoted and springheld, so that it, as it strikes and cuts through one ply of the tube, travels forward with the tube until the cutter is lifted out of engagement with the tube, when the spring restores the cutter to its normal position. This cutter co-operates with a lip-support on the former, about which the tube is formed, the said lip-support sustaining only the upper ply of the tube.
Figure 1 represents in top view a sufficient portion of a paper-bag-making machine to illustrate my presentinvention Fig. 2, a section thereof on the line as :0, Fig. 1; Fig. 3, a detail in top view, showing the lip-support of the former.
In the drawings, the former [1-, placed within the folding-guide Z I), of usual construction, has a web of paper folded about it to form a tube, 0. the upper ply of which, at or near the end of the former, is supported on the lip-support (I, which is, as shown, a detachable metal plate curved at its end.
The feed-rollers e e are and may be of usual construction.
Thelip-cutter f, curved or shaped as a gouge, is hung loosely on a pivot or bolt, g, of an arm, 9', secured .toa rock-shaft, 9 it having i a second arm, 9 connected with rod h, provided with a roller, h acted upon by a cam, W, on shaft h, the said cam operating the rock-shaft and lip-cutter at the proper times to lift the lip-cutter and keep it above the web of paper, a spring, '5, connected at one end with the said rod h, operating, when permitted by the depression in cam 71. to turn the rock-shaft g and cause the lip-cutter to descend quickly upon and cut the upper ply only of the tube 0 at the end of the lip-support d. As the lip-cutter approaches and strikes the tube, the spring I is effective to hold the lower end of the cutter in such position as to strike the moving paper tube in line with the end of the lip-support d; but as the movement of the tube is not arrested, the lower end of the lip-cutter is, by the said spring I, per
mitted to move forward with the tube without straining or detaining it, the lip-cutter then turning on the pivot or bolt 9 forward from the position shown in Fig. 2, but as soon as the arm 9 is lifted by the action of the cam h the spring Z immediately restores the lip-cutter to its normal position. The screw m limits the movement of the lip-cutter on the pivot gand insures its position when descending. The shaft h also carries the blade n, which is employed to sever the tube into bag lengths. The lip-cutter, being connected with the arm of a rock-shaft, is made to reciprocate toward and from the tube, and to vibrate about its axis of suspension as it moves forward with the tube. v
I claim 1. In a paper-bag machine, a vibrating lip-- cutter adapted to strike and cut through the upper ply of and moveforward with the moving tube until lifted therefrom, substantially as described. I
2. The rock-shaft g its arm, and lip-cutter f, pivoted thereon, and spring to control it, combined with the former and lip-support located within the tube, to operate substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
CLARENCE A. CHANDLER.
