SHAFTHANGER `AND BEARING.

SPECIFICATION forming part of Letters Patent No. 712,392, dated October 28, 1902.

x Appnatnnnea .lingue 14, 1901. sean No. 72,059. (No model.)

To (LZ/ whom itmcty conce/'17,: y o y 1 Bc it known that I, EMERSON O. LEAN,` a citizenof the United States otAmerica, and a resident of Mansfield, county of Richland, and Stater of Ohio, have invented certain new and usefulImgnovennents` in Shaft Hangers and BearingsVof which thev following is a specification.` y y My invention relatesto improvements in shaft hangers and bearings, its objecrsbeing strength and cheapness,.combinedfwith `simplicity and compactness of construction, as well providing a"continuouslylubricated bearing for the shaft or axle to whichit may be applied. U t t u A further object is to provide a construction wherein the bearings may be easily and quickly removed andreplaced for thepurpose of rebabbit-ting;l or to insert anew bear-` ing-box. t o

My 4invention further `consists in certain novel features of construction and combinations of parts, as Will be more fully described hereinafter and particularly pointed out in the claims. V

In the accompanying drawings, Figure l shows a perspective View 0f my improvement as applied to anaxle of a roller, disclosing the frame, hanger, and bearing-box in position. Fig. 2 is an enlarged View of the hanger detached, showing the means of securing the bearing-box therein. Fig. 3 is a detail view of the frame. Y Fig. 4 is a detail view in perspective ofthe bearing-box, showing the rear end thereof. Fig. 5 is a vertical the front end thereof; and Figs. 6 and 7 are vertical longitudinal sectional views ofa modication of the bearing -box shown in Figs. 4 and 5, the latter view showing the manner of securing the bearing-box.

A represents the frame. ed in any suitable manner; but preferablyit may be composed of angle-iron joined together in any approved Way. At each end of the frame hangers B depend. These hangers have a V-shaped contour in general outline. Theupper ends l of thehangers are of an `L-shapedv form, or they may be of any other form suitable for the purpose. Apershaft or axle in the .tures 2 2 are formed through eachside of This is construct- `that portion of the hanger forming the angle.

`The upper ends of the hanger are designed `t0 embraceand clasp the ends of the frame, as shown. Pieces of angle-ironic' lo are inserted between the longitudinal pieces l5 l5 of frame A and the hangers B, which pieces 16'16 areadapted to coincide and nest into the angles formed att'ne upper ends of the hangers. In the drawingsthese hangers ls` B shown as having `their upper ends 1 l of right-angle form; but it is obvious that `any other form could be used without departing from rheinvention. Bolts 44eme inserted through apertures 2 2 in the hangers and similar registeringholes in the angleirons and frame, wherebyio fastenthe hangers and angleeirons rigidly and securely to` the frame. The idea of theangle-irous is to add strength and rigidity to that part of the construction. The lowerclosed ends 5 5 of the hangers form `yokes and may be of any desired shape, but are preferably angular, as shown. Apertures 6 .areformed near the upper end of the angularportion for the reception of a bolt 7, for a purpose hereinafter described.

The bearugboxes C, as shown, (but, however, they can be made separate,) consist of one integral piece of metal havingan irregularly-shaped recess Slformed-theren. `These bearingboxes are designed to receive and fit upon an axle or a shaft, as may be. Flanges 9 9 are formed upon and extend outward from the box on three sides thereof, forming Ways therebetween. These boxes are adapted to rloe recei ved in the yokes formed by the hangers, the straps composing the hangers fitting between the flanges 9 9, which embrace the sidesof the hanger, and the bolts 7 are then passed through the hangers above and in contact with the bearing-boxes,whereby the boxes are removably and securely retained in the hangers. '[he boxes are provided With arcshaped fianges 13, as shown in Fig. Il, on their inner sides, which act as dust-protectors.

e The upper portion 1l `of the irregular recess 8 in the bearing-box is designed to receive and removably retain an arc-shaped Vpiece of antifriction or Babbitt metal, shoulders lO l0 being formed in the recess, upon which the ends of the bearing metal rest. This bearing metal may be easily removed in IOO any convenient Way and replaced by a new piece when necessary or desirable. The lower portion 12 of the recess 8 is cup-shaped and is designed to receive Waste saturated with lubricant, whereby to keep the revolvingshaft or axle properly greased at all times. A lubricating groove orduct 12 is formed through the top of and continued on the interior face of the bearing-box C, whereby the lower recessed portion 12 may be kept continually lubricated. y

As shown in Figs. 1 to 5, inclusive, of the drawings, the recessed portion of the bearingbox C extends through only one end thereof, the opposite or outer end 14 being closed to form a dust-protector for the bearing-box, or n the shaft can be left projecting and a washer placed thereon for the purpose of a dust-protector and to keep the hangers from spreading, as shown in Figs. 6 and 7.

The above-described construction is simple, neat, compact, and strong, and may be applied in a varietyof Ways to several differsent arts, and therefore-it is evident that slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hencel I do not Wish to limit myself to the exact construction herein set forth; but,

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

1. A frame comprising sides and ends of angle-pieces, the end pieces received between and resting upon the side pieces, a hanger, comprising a closed lower end, converging sides and an open upper end, the upper ends of the sides of the hanger having angular recesses therein for the reception of the frame, bolts extending through the upper ends of the sides of the hanger and through the side and end pieces of the frame to secure the parts together, a bearing-box received and held in the closed lower end of the hanger and means for removably retaining it in place.

2. A shaft hanger and bearing comprising a plurality of longitudinal L-shaped pieces, a plurality of similarly-shaped end pieces receivedbetween and resting upon the horizontal flanges ot' the longitudinal pieces, depending integral hangers consisting of converging arms closed at their lower ends, the longitudinal pieces embraced by and resting upon the upper ends of the hangers, a single securing means extending through each arm of the hanger and through the longitudinal `pieces and the end piece whereby to secure the entire structure together and a bearingbox received and retained in the closed lower end of the hanger.

3. A shaft hanger and bearing comprising asuitable support `consisting of longitudinally and laterally extending angle-irons, the laterally-extending angle-irons received between the longitudinally extending angleirons, and hangers, the upper ends of which are provided with shoulders upon which the longitudinal angle-irons rest, there being upstanding ends on the shoulders which embrace the longitudinal angle -irons and securing means extending upward through the respective shoulders, through the respective longitudinal angle-irons and through each end of the respective lateral angle-irons whereby to fasten the structure together.

a suitable support, depending integral hangers consisting each of a pair of converging arms having closed lower ends, bearing-boxes received between the converging arms in the lower closed ends and resting thereon, and

verging arms above the bearing-box to retain the latter in place.

5. A shaft hanger and bearing comprising a frame, the frame consisting of angular side pieces, and angular end pieces received loetween and supported upon the horizontal flanges of the side pieces, integral hangers closed at their lower ends, the hangers consist-ing of two converging arms, the upper ends of the arms provided with angular'extensions corresponding in shape to the angular pieces of the frame, the frame resting upon the angular extensions and embraced thereby, securing means passing through each arm of the hanger, the side pieces and the end pieces, and bearing-boxes adapted to be slid into and out of the hangers, the boxes .supported by the closed portion of hangers which conform in shape to the shape of the boxes and removable means passing through` and connecting the arms of each hanger above the boxes, the removable means contacting them in place.
