LOOM-SEAT.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed February 13, 1918. Serial N 0. 216,846.

Hopedale, county of Worcester, State of.

Massachusetts, have invented an Improvement in Loom-Seats, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

The object of this invention is to provide a seat for the operative of a loom or other similar piece of machinery so constructed and arranged that it will present a firm and durable seat Occupying a. minimum amount of-space and when not in use shall be movable into an inoperative position close to the loom or other frame and shall be yieldingly held in such position.

The nature and objects of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings,

. Figure 1 represents a front elevation of a portion of a loom or other machine frame with the seat embodying the invention in its closed or inoperative position;

Fig. 2 is a side elevation of the construc tion shown in Fig. 1, the dotted lines representing the parts in the position as shown in Fig. 1 and the full lines representing the seat in open or operative position;

7 Fig. 3 is a view in transverse cross section of the construction shown in Fig. 2.

The invention is peculiarly adapted to a loom frame but is obviously useful in connection with other machines or structures wherein it is desired to have a movable seat of the character in question.

It is essential that the seat when in open or operative position shall present a firm and rigid structure capable of sustaining the weight of the operative and which shall occupy a minimum amount of space. It is also desirable that the seat shall be folded to a closed or inoperative position snugly against the loom frame and entirely out of the way. It is desirable also that the seat shall remain in operative position unless positively moved by the operative to bring it to the inoperative position. If the seat automatically moves to inoperative position the operative having once placed the seat in operative position may expect it to remain there and may sit down without looking and be seriously injured.

In the construction illustrated, the seat is connected to the loom frame 1 through the medium of a bracket 2 in turn adjustably connected to the loom frame, and this bracket is a valuable feature of the invention because it enables the seat readily to be attached to any frame and in any desired pos1t1on.

In the construction illustrated the loom frame 1 is shown as made of channel or angle iron presenting a flange. The bracket 2 is a split bracket made in two parts enabling it to be clamped about the flanged vertical edge of the loom frame. The part 3 of the bracket is dove-tailed or fitted into the part 4 at the abutting edges. The part 3 fits snugly up against the side face of the frame and the part 4 is bent or formed to fit around behind the flange and is provided with ribs 5 to position it against the flange and against the other part 3. The two parts of the bracket areforced together into clamping engagement with the frame by a bolt6. A set screw 7 passes through the rearwardly projecting portion of the part 4 and abuts the inside of the frame 1 and locks the bracket at any desired point of vertical adjustment. There is thus provided a very simple and efficient means of connecting the seat to the loom frame.

' The seat proper 8 is preferably formed by striking up a metal plate into the desired shape. This plate on the underside is formed with two downwardly projecting lugs 9 and 10.

A strut or compression member 11 is pivotally mounted at its upper end to the lug 10 being journaled on a pin 12 projecting laterally from the lug 10 and held in place by a cotter pin 13. At its lower end the compression member 11 is provided with a hub 14 journaled on a stud or pin 15 projecting laterally from the lower end of the bracket 2 and is likewise held in place by a cotter pin 16. This compression member is formed in a rigid manner being preferably provided with a web or rib 17 so as to sustain the weight of the operative.

A- tension member 18 is pivoted at its upper end to the lug 9, a ournal pin 19 projecting from the tension member passing through the lug 9 and being held in place by a cotter pin 20. At its lower end the tension member is journaled on a pin 21 projecting from the upper end of the bracket 2 and is held in place by a cotter pin 22.

The compression member-and the tension member are of such length that when the seat is swung to operative position the seat will be horizontal and will be held rigidly in position. In order to secure a desired steady horizontal position of the seat the strut member is provided with a laterally projecting lug 23 at its upper end against which the seat plate rests when in horizontal. position, the seat plate being flattened preferably opposite said lug to cooperate therewith.

With this construction when the seat is swung to inoperative position up against the side of the frame it will assume the position indicated in dotted lines in Fig. 2 with the seat plate lying against the face of the frame and the compression and tension members passing to the side of the frame thus assuming a position entirely out of the way.

A. coiled spring 24: surrounds the hub 14; of the compression member and engages at one end the compression member and at the other end the bracket and acts to move the parts to inoperative position. The tension of this spring is so arranged that it will not act to move the parts when the seat is in its operative position but as soon as the seat has been swung by the operative partially to a closed or inoperative position the force of the sprin will be suflicient to carry the parts to t e closed or inoperative position and hold them there, thus requiring a positive movement by the operative to again swing them to open or inoperative position.

Itwill thus be seen that the seat when open presents a firm, solid structure occupying a minimum amount of space, that when closed it is entirely out of the way and is held closed by the spring, and that when once moved to open or operative position it will not return to its closed or inoperative ppsition except by the positive act of the operative.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is: j

1. A folding seat for looms comprising a bracket and means for attaching it to the loom frame, a seat plate, a compression member pivoted to said seat plate and to the lower portion of said bracket, a tension member pivoted to said seat plate and to the upper portion of said bracket,.the said members acting when the seat is in operative position to suetain the weight of the operative and permitting the seat to be swung up against the loom frame out of the way, and a laterally projecting lug on the upper end of one of said members contacting with the bottom of said seat plate when in operative position and acting to position it horizontally.

2. A folding seat for looms comprising a two-part bracket and means for clamping it to the edge of a loom frame, a seat plate, a

compression member pivoted to said seat plate and to the lower portion offsaid bracket, and a tension member pivoted to said seat plate and to theupper portion of said bracket, and a laterally projecting lug on the upper end of one of said members contacting with the bottom of said seat plate when in operative position and acting to position it horizontally.

In testimony whereof, I have signed my name to this specification. V
