IMPROVEMENT IN HANGER-BOX FOR (iRANK-SHAFIS.

TO ALL WHOM IKT MAY OONCERN:

Be it known that I, THOMAS WELCH, of Chnrchville, in the `county of Monroe, and State of New York, have invented a new and useful Hanger-Box for the Crank-Shaft and other Johrnais'of Harvesters; and I do hereby declare that the following is a full, clear, and exact description thereof', reference beingl hadto the accompanying drawings, making part of this specification, in which- Figure 1 is a top view of my invention, thetop plate or cap of the case A being removed.

Figure 2 is a vertical section of the same, taken in the plane indicated by the red line o, iig. 1.

Figure' is a transverse vertical section, taken in the plane indicated by the ied line n, in gs. l, 2, and

Like letters indicate corresponding parts ih all the figures.

This invention consists, mainly, in providing the crank-shaft of harvesters withself-adjusting, or self. lining boxes; and in providing the said boxes and journals with an oil-chamber or reservoir, anda wick or stnfflng, whereby the oil is conveyed to the end of the journal, whence it is distributed over, the whole bearing.

To enable others to make and use my invention, I will describe its construction and operation.

I provide the caseAv with a division plate or rest R, upon which the boxes B and B are supported. This plate extends from side to side of the case, laterally, but an open space, C and D, is left at the ends. The space C is divided from the balance of \the chamber by bars a, figs. 2 and 3, and constitutes a sort ofvpaclring cage for 4cotton waste or other suitable material. There is an opening lil-through the plate R, through which the end of the adjusting wedge E may pass. This wedge has a cylindrical face next to the box `B, and ts in the corresponding-shaped recess in the back of the box. The set-screw Siis designed to secure the proper adjustment of the Wedge against the box, by preventing it from working up the inclined plane and thereby loosening the' boxes. The box B is similarly fitted to a projecting rib F on the case A. The box B is made somewhat shorter than the other, as shown in iig. l, so as to permit the stuiing or waste to come in Contact with the journal J.' There is an opening provided in the cap, I, over the point G, (g. 1,) through which opening the' waste or stuihng is applied. The cap, I, is made with an arch or elevation L, iig. 3, to make room for the r wedge. The set-screw, S, is' tapped through'this arch and acts against the top of the wedge, and b'y this means the parts maybe tightened up. at any time to compensate for any Wear that may occur between the parts. The top and bottom of the boxes, B and B, are made convex, longitudinally, as shown in g. 2.. They may be made of chilled iron, and by means of the provisions made for their rocking. horizontally and vertically, they will line themselves to a perfect t to the journal or shaft J without babbeting, and thereby accomplish1 the object by a much simpler and cheaper method, and at the same time provide a much more substantial and durable box. The boxes may rest upon ribs, top and bottom, similar to rib F if desired, or the ribs in either case may be upon the boxes and the case recessed. If ari-,iron frameis used for the machine, the case may be cast with the frame, and`the` cap, I, cast on or made separate and attached with bolts. If the-cap'is cast to the ease, the wedge, Eshould be inserted and held with the upper end against the arch,` until the boxes and shaft J are inserted and properly adjusted, when the wedge may drop to a bearing between the box B, and inclined plane K, and the set-screw S turned Adown against the top of it. These boxes, B and B', may be taken from the sand andrattled, `or otherwise cleaned, and-adjusted inthe machinev as ab'ove described, without any other itting.- Brass or any other suitable materialv may be used for the boxes. vThe wedge may be dispensed with,

l by placing the set-screw S in the side of the case, so as to screw against the back of the box. A wedge or a i set-screw might 'be used against the b c oth boxesit' desired. A set-*screw may be used on the top of the boxes, by having an intervening late for the oint of the screw to rest against.

What I claimas my inve tion, and desir to secure by Letters Patent, is-

l. Providing. the `ligger-journal of th crank-shaft, o r other journals of harvesters, with self-adjusting or self-liningi/leaings or boxes, substantially asand for the purposes shown and described.

2.A The application of the wedge E, with or without a set-screw, when used in combination with the box, in y which the journal revolves,for the purpose of compensating for the slack that might otherwise occur by the wearing away'of the parts. l

3. The setjscrew S, in combination with the self-adjusting or self-lining boxes of harvesters, substantiallyl as and for the purposes lset forth. A I

L5..v In combination with the self-lining or adjusting boxes and journals, the oil reservoir, substantiallyas shown, and for the purposes described. l

5. In combination with a set-screw and self-lining or self-adjusting boxes, in harvester's, the cap I, or its equivalent, for the purposes described.
