ABRAM BRIGHAM, OF MANCHESTER, NEW HAMPSHIRE.
LOOM.
Specification of Letters Patent No. 12,120, dated January 2, 1855.
To all whom may concern Be it known that I, ABRAM Brief-IAM, of Manchester, in the county of Hillsborough and State of New Hampshire, have invented a new and Improved Method of Weaving Seamless Bags; and I do declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and the signs of referencel marked thereon.
To enable others skilled in theart to make and use my invention, I will proceed to describe its construction and operation.
I construct the loom in any of the common forms of wood or iron or both. For common or plain bags, I use four treadles or levers to operate the harnesses, which I do with four cams'placed on a short shaft, driven by the main shaft, near the center of the loom. The treadles are secured by a stand made fast to the back girt of the loom. The other ends of the treadles `are attached to the harnesses in the usual manner by a strap or otherwise. I raise the harnessesl with spiral springs made of the best iron wire, which I prefer to any other mode. The treadles I make in the common form with a tappet made of chilled iron on which the cams operate to move the harnesses. The cams I make also nearly in the usual form, with the exception of the fourth. On the fourth cam upon the outward side, I cast a lip or projection extending wide enough to operate on a slide made of wood or iron, to which I fasten a tappet in the same manner I do to the treadles. The slide extends no farther forward than the tappet, and is not attached to the harnesses but to the fourth treadle. In this slide, I make one or two slots of suilicient length to move back and forward a sufficient distance to clear the lip on the fourth cam, when the loom is One slot moves on the pin in the stand which holds the treadles to the back girt. The other slot moves on a screw or stud-pin made fast to the fourth treadle, but slides perfectly easy on both. Vhile the tube is being woven this slide and tappet are held back by a spring or otherwise far enough to clear the lip or projection on the fourth cam. But when a tube is woven of suflicient length, and a bottom is required, this slide and tappet are brought forward to operate on the lip or projection on the fourth cam, and are there held long enough to form the bottom of the bag. When the bottom is made the slide and tappet are moved back again and are held by a spring or other means until another bottom 1s to be made, when they are again woven, and so on until the whole web is woven, without stopping the loom to weave the bottom. The length of the bag is governed by the cloth roller, and such bag can be made of any required length,- and every one be precisely alike.
Figure l, shows a side elevation of the fourth cam and lip or projection for weaving the bottom of the bag. The lip is shown more distinctly and in a working condition at p, Fig. 6. A front View of t-he same cam looking from C to D, is given at Fig. 2. A vertical section is given at Fig. 3. Other views are given in Figs. 4, and 5. Fig. 6, shows a side elevation of the fourth c'am, with the lip or projection, and the fourth treadle or lever with slide and tappet attached'.
A, Fig. 6 shows the position ofthe slide and tappet while the tube is being woven.
B, Fig. 6 shows in dotted outlines the positio-n of the treadle and slide while the bot- .tom of the bag is being woven.
S, is the studpin or screw `which is made fast to the treadle thevslotted slide moving forward and back on said st-ud pin. pin where the treadles are all attached on the back of the loom.
t, is the tappet.
hub of thev cam an oval or convex surface for self adjusting and fastening the cams.
Fig. 7, shows an intermediate cam, with four concave surfaces on both sides of the hub as shown at 9, and corresponding exactly in size with the convex ones in Figs. l, 2, 3, &c. They are shown in section at r,
