ADJUSTABLE LOOM BEARING.

Application filed April 23,

The present invention relates to a bearing and has for its principal object to provide an adjustable structure for taking care of wear of a shaft operable therein and wear in the bearing itself.

Another important object of the invention is to overcome some of the disadvantages and object-ions common to many contrivances heretofore devised for a similar purpose and to provide a hearing which is simple in construction and reliable during operation and in adjustment, besides possessing the capacity for long and continued service.

\Vith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: 7

Figure 1 is an outside view of the left end of a loom showing my improved bearing mounted thereon,

Fig. 2 is an inside view thereof,

Fig. 3 is a rear View thereof, and

Fig. 4 is a detail perspective of the bearing casting.

Referring to the drawing in detail, it will be seen that I have illustrated by way of example the use of my improved adjustable loop bearing on a loom for the purpose of journaling the beam shaft, but it is to be understood that the bearing is by no means limited to this use, but is of universal application.

The numeral 5 denotes the left hand end of a loom frame on which is supported my improved bearing which includes generally the bearing casting A and the bearing top casting B. The casting A comprises a body 6 having an opening 7 extending therethrough countersunk with a polygonal recess 8, an extension 9 being provided at one corner of the body and having an arcuate bearing surface 10 which is extended as at 1.2.

An arcuate lip 13 extends from the other corner of the body. The extension 9 has a head lat at its terminal extended as at 15 to form the crotch 16 while its other end is extended laterally as at 17. The casting B is of a general arcuate formation having an elongated slot 19 at one end and a pin 20 at the other end thereof projecting laterally from each side thereof, while intermediate its surface it is provided with the bearing 1326. Serial No. 104,106.

surface 21. The casting A is held in place by a bolt 23 piercing the opening 7 and having a nut in the counter-sunk recess 8 and a lock nut This bolt extends through an opening provided in the loom frame 5. The nut 2% provides the necessary adjustment. This bolt extends through the slot 19 of the cap bearing casting C and the nut 2st may be tightened for holding the cap casting adjusted as desired. It is to be noted that the pin 20 is rockable in the crotch 16.

The extensions 12 and 13 overhang the frame, the extension 12 overhanging the bearing portion of the frame. The warp wound about a wooden beam 26, about six inches in diameter into which from each end for about two feet shafting 27 is inserted. hen the beam is full of warp it is of considerable weight, and where the shafting bears on each end of the loom frame, there is considerable strain. The bearing is narrow and the weight and strain wears the shafting rapidly. In addition to the weight of the warp on the bearing, the warp runs up and over a steel beam (not shown), which when. the loom is in motion, works up and down, feeding the warp toward the weaving apparatus. This slight up and down motion will lift and drop the warp beam causing further wear on the shafting of the warp beam.

1V ith my improved adjustable bearing, however, these disadvantages are overcome. The bearing can be attached to practically any standard loom without boring additional holes in the frame of the loom. This bearing affords additional bearing surface 11 and 12 for the beam shaft as the surface 11 is level or flush with the usual bearing on the loom. The bearing allows the shaft to be readily taken outor put in place when necessary.

It will be seen that the bearing is also useful in general application, having practically the same advantages as those enumerated above and others which will be quite apparent. It is thought that the construction, operation, and advantages of this invention will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed merely by way of example, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It

will be apparent, however, that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the scope or spirit of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, What I claim as new is 1. An adjustable loom bearing including a bearing casting comprising a body having an arcuate extension provided with a bearing surface, said extension terminating in a head forming a crotch with the edge of the body remote from the bearing surface, said body having an opening to the side of the body remote from the extension, a top bearing cast- I ing having at one end a transverse slot and at its other end a lateral pin rockable in said crotch, a bolt for passing through the opening and the slot and adapted to pass through an opening in the loom frame, and a nut on the bolt, said top bearing casting having a bearing surface intermediate its end to en gage the loom shaft and hold it in the first mentioned bearing surface.

2. An adjustable loom bearing including a bearing casting comprising a body having a bearing surface, a head formed on the body to one side of the bearing surface and forming a crotch with the edge of the body re mote from the bearing surface, said body having an opening to the side of the body remote from the head, a top bearing casting having at one end a slot and at its other end a lateral pin rockable in said crotch, a bolt for passing through the opening in the slot, and a nut on the bolt, said top bearing casting having a bearing surface intermediate its ends to engage the loom shaft and hold 40 it in the first mentioned bearing surface.

In testimony whereof I affix my signature.

MAJOR P. OWENS.
