sriNnLn-BRAKE roe SPINNING, on, TWISTING APPARATUS.

Be it known that I, ALoN zo E. Rnoanns, a citizen of the United States, and resident of Hopedale, county of \Vorcester, State of Massachusetts, have invented an Improvement in Spindle-Brakes for Yarn Spinning or lwisting Apparatri s,.of which the following description, in connection withthe accompanying drawing, is a specification, like characters on the. drawing representing like parts.

This invention relates to apparatus for spinning or twistin yarn, and it has for its 'p'articularobjeet the production of novel and efficient means for stopping the rotation of a spindle when so desired, this up lication being a division of anal plication eria'l No. 467,252 filed byme tlie 12th day of December, 1908. V

When an end breaks the corresponding spindle must be stopped while the end is pieced up, and such stoppage is effected by a spindle brake adapted to be actuated by the knee of the attendant, thereby leaving the hands free. The orclinar spindle brake,- is so constructed that oil from the, spindle bear-in frequently trickles down onto the face 0 the knee-plate of the brake. so that the clothing of the attendant gets very oily and dirty by the operation of the brake, making this feature of spinning or twisting appaviated.

ratns very obj cetionable' a nd disagreeable. In my present invention I have so constructed the spindle brake that the oil cannot collect on the faceof-the-knee late, and the-objections above "mentionec are wholly. ob

' The various novel-features of 'my-inv'en tion will be full described in the subjoined s ecifieation and particularly pointed out in tiie following cla1ms. I

Figure 1 is afront elevation of a suflicient portion of a twister to be understood, with a s indle'brake embodying my invention ap ied thereto; Fig. 2 is a side elevation o the spindle brake and some of the parts shown in.'Fig. 1, other parts being shown in er'oss-section;- Fig. 3 is an enlarged front view-of the spindle brake, detached; Fig. 4 is a rear view of a portion of the brake, showing-the oil catcher; Fig.5 is ascctional detail onthe'line 55, Fig. 4.

' Original application filed Dedember 12. 1908, Serial No. 467,252. Divided .12, 1910. Serial No. 548,909.

Patented Dec. 6,1910;

{ ing ring-rail C having a ring for each 9 spindle, may be and are all-of usual or well 3 known construction, the spindle having a suitable band-whirl and this application filed March E by means of which i l the spindle is rotated, it being understood that the spindles are arranged in series, as is customary, with a brake.

As herein shown the u t the brake is provided with urned arm 1' of i seat 3 which rests upon the top of the spin dle-ra'il B is made 0 nto loosely embrace the base of the spind e-bearing, and the bifurcated leg 4 depends from the seat 3 at its plate 5, such parts of the brake being subherein the lower endof the leg is turned forward, at 6, where it joins the knee-plate. I have also rcarwardly beveled the upper edge ot the plate, as at 7, Fig. 5, and the bottoinof the opening in the leg extends below the up er edge of the late, as at 8, and a vertica rib 9 is formed on the back of the plate, as a continuation of the bottom of the leg, said rib terminating in a point 10. Any oil collecting on the brake will sooner or later trickle down the leg 4, and if on the backthcrcofWfll run down the rib 9 and drop to the ..oor off the point 10, anicl if the oil traverses the front of the'leg it meets the beveled edge 7 of the ,k-nee-plate, and collects in the.depression 8, tra\'eling thence over the back of the leg below the @depression and off alon ..Iathe rib'9 as before. As'

.the front face ott 1e"'.kneelate is oifset from the front of the legit wil be manifest that the collected eil cannot in any case travel 'onto the front ofthe-plate, and therefore tl front'face will alwa s be kept clean and wholly. free jroln oil I thus obviate the .objections heretoforenql ed and prevent the transfer of oil to the clothingsor'person of the attendant.

As shown best in Fig. 3the upper ed e of the knee-plate is made slightly concave rom one to the other end, thiscurvature assisting in directing the travel of the oil to the entral depression 8 behind the plate. 1

. The construction of the brake is simple it is eflieient in operation, and-is clean a d free from oil at all times, preventing any iling front, terminating in a broad and flat knee-J and-each spindle is provided;

a friction-pad 2 i 2 adapted to bear against the spindle above 3 the whlrl and thereby stop rotation, and the stantially of usual construction, except that ofthe clothing of the attendant when operating the brake.

Having fully described my invention, What I claim as new and desire to secure by Letters Patent i's 1. In apparatus of the class described, a: spindle-rail, a spindle rotatably mounted thereon, a spindle-brake seated on the rail its lower end with spindle-rail, a spindle rotatably mounted thereon, a spindle-brake seated on the rail and having a leg depending in front of-and below the rail and provided with a kneeplate' set forward from the le and beveled rearwardly at its upper ed e the leg havim a depression therein behiri d and below the beveled edge of the knee-plate, to collect oil accumulating on the leg and prevent its passage to the front of the plate.

3. In apparatus of the class described, a spindle-rail, a spindle rotatably mounted thereon, a spindle-brake seated on the rail and having a leg dependin in front of and below the rail and prov-idled with a kneeplate set forward from the leg and beveled rearwardly at its upperedge, the leg having a depression therein behind and below such edge, to receive oil collecting on the leg, and a rib on the back of'theplate communicating with the end of the leg, to direct oil from said depression and discharge it at the lower edge of the knee-plate at its back.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
