1400M ATTACHMENT.

Specification of Letters Patent Patented July 13, 1915.

To all whom it may concern:

Be it known that 1, CHARLES C. EVANS, a citizen of the- United States, residing at Gainesville, in the county of Hall and State of Georgia, have invented new and useful Improvements in Loom Attachments, of which the following is a specification.

The invention relates to loom attachments, and more particularly to the class of picker stick checking devices.

The primary object of the invention is the provision of a checking device wherein the picker stick on movement thereof is retarded at the end of its forward and rearward strokes so as to avoid any pounding or hammering of the same while in action, and thus checking the throw of the said picker during the working of the loom, the checker being of a novel construction to increase the life of the same.

Another object of the inventionis the provision of a checking device which is extremely simple in construction, readily and easily adjusted, thoroughly reliable and efficient in its operation, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.

In the drawing Figure 1 is a side elevation of a checking device with the picker stick in relative position thereto. Fig. 2 is a top plan view of the checking device. Fig. 3 is a sectional view on the line 3-3 of Fig. 2.

Similar reference characters indicate corresponding parts throughout the several views in the drawing. v v

Referring to the drawing in detail, A designates generally a picker stick of a loom,

'and'B the checking device therefor, which comprises a substantially U'sha'ped frame '5, preferably made from a steelbar bent into the required shape, and has passed through the free ends thereof a transverse bolt member 6, the head 7 of which engages the outer face of one of the ends, while the opposite threaded end 8 of the bolt carries adjustable jam nuts 9, the same being disposed against opposite faces of the other end of the frame so as to fasten the ends of the frame together.

Mounted within the frame 5 and suitably secured to the side bars thereof are outwardly bowed resilient members 10, the ends of which are extended for a distance in parallel relation to each other, and a pair of the said ends are formed with openings 11 receiving the bolt member 6, while fixed to the closed end of the frame 5 is a bufier spring 12, the same being upwardly arched and has its free end extended between the opposite ends of the members 10 so that the picker stick A working between these members 10 will strike the spring 12 in its rearward stroke so that the spring will absorb the blow.

The inner faces of the members 10 have fixed thereto leather strips 13 which extend throughout the end portions of the members and against which frictionally engages the picker stick A during its forward and rearward stroke so that the throw of the picker stick will be retarded atthe ends of its strokes during the working of the loom.

Formed in one side bar of the frame 5 and the member carried thereby are alining elongated slots 14: in which is adjustably engaged a securing bolt 15, the same adapted to be mounted on the shuttle frame or box (not shown) of the loom, said frame or box being of the ordinary well-known construction. It will be noted that the frame 5 can be adjusted on the shuttle frame or box relative to the throw of the picker stick A.

Surrounding the bolt member 6-are coiled compression springs 16, the same being dcthereto' of the members 10 to hold the same in close relation to each other for checking the forward stroke of the picker'stick during the working of the loom.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is:

A loom attachment comprising a U-shaped frame, a cross bolt fastened in the free ends cf the limbs of the frame, outwardly bowed resilient members disposed longitudinally within the frame, means for securing the bowed portions of the members medially thereof to the limbs of the frame, the said members being'provided with slots in their ends located at the open end of the frame 90 signed to work against the ends adjacent members at the inner faces thereof and for a distance from the opposite. ends of the same, and a'bufier spring fixed to the closed end of the frame and having one end bent to lie between the innermost ends of the re- 9 silient members.

In testimony whereof I affix my signature 1n presence of two wltnesses.
