SAMUEL B. TAFT AND LOUIS H. LANDRY, OF UXBRIDGE, MASSACHUSETTS.

PATTERN-CHAIN RACK.

To all whom it may concern:

Be it known that we, SAMUEL B. TAFT and LOUIS H. LANDRY, citizens of the United States, residing at Uxbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Pattern-Chain Racks, of which the following is a specification.

This invention relates to pattern chain racks or supports adapted to be attached to a loom.

The object of this invention is to provide a pattern chain rack or sup-port, and to construct the same in such a manner that it may be easily and quickly adjusted to a loom and the arms drawn together or spread apart, also to provide means whereby the slide may be adjusted at any desired angle.

Another object of this invention is to provide a pattern chain rack or support and to construct the same in an exceedingly cheap and simple manner, yet durable, reliable and one that will eificiently perform all of its intended functions.

In the drawings forming a part of this specification the figure is a perspective View.

Referring by numerals to the drawing, 1

represents corresponding and oppositely disposed arms or plates constituting a frame and provided with angular base pieces 2, having slots 3, by means of which they may be adjustably secured or mounted upon the frame of a loom. These arms are further provided with flanges, and guides 4;, which are formed integral with the arms and are adapted to retain the chains in position and guide the same. The arms are adjustably secured together by means of a transverse bolt 5, which is provided with nuts 6, upon the respective sides of the arm thus forming a rigid yet adjustable connection; The free ends of the arms are curved up as shown at 8, and are provided with adjustable bolts 9, upon which is pivoted the slide 10, consisting of two parallel bars 11, connected by transverse braces 12, 18 and 1 1.

Pivoted to the sides of the arms 1, are rods 15, which are bent approximately near their centers, as shown at 16, so as to bring their upper ends flat against the sides of the slide which is provided with adjustable clamping bolts 1'7, in engagement with the slot 18 in the rods, thus providing means for adjusting the slide at any desired angle.

In operation the pattern chain passes be- Specification of Letters Patent.

tween the plates 1 at the top thereof, and the shafts of the pattern chain which extend at intervals on each side rest on the top surfaces 20 of these plates. The chain passes along to the right and up over the slide 10. It will be seen that the plates 1 can be adjusted very quickly and easily to the loom and placed at the desired distance apart, being held by the bolts passing through the slots 3, and that the inclination of the slide 10 also can be readily adjusted. Yet the mechanism is exceedingly simple and inexpensive.

Although we have illustrated and described a single embodiment of the invention and shown the details thereof, we are aware of the fact that the invention can be carried out in other ways without departing from the scope of the invention as expressed in the claims. Therefore we do not wish to be limited to all the details of construction herein shown and described.

Having thus described the various features of our invention, what we claim as new and desire to secure by Letters Patent, is

1. As an article of manufacture, a pattern chain support comprising a horizontal frame, means for securing one end of the frame to a loom, a slide pivoted at the other end of the frame and extending upwardly from its pivots toward the loom, and means between the ends of the framefor adjusting the angle of said slide to the frame.

2. A pattern chain support consisting of parallel arms, means for adjustably mountmg the arms upon the frame of a loom, means for adjusting the arms together, flanges and guides integral with the arms, the free ends of the arms being curved upward, a slide pivoted between the free ends of the arms, rods for supporting the slide, and adjustable connections between the slide and supporting rod.

3. A pattern chain support consisting of two corresponding and oppositely disposed arms, an angular base upon each arm having a slot therein by means of which it may be adjustably mounted upon the frame of a loom, flanges formed integral with the arms,

guides adjacent to the flanges, the free .ends of the arms being curved up, adjustable bolts for clamping the arms together, a slide pivotally mounted upon adjustable bolts between the free ends of the arms, rods pivoted upon the sides of the arms, the upper ends of the rods being slotted, an adjustable extending upwardly therefrom toward the bolt mounted in said slide and in engage- 100m frame, and adjustable means on the ment with said slot. arms for supporting the opposite end of said 4. In a pattern chain support, the eombislide at a higher elevation than the free ends 5 nation of a pair of parallel substantially f the rms.
