SHAFT-HANGER.

SPECIFICATION forming pait of Letters Patent No.- 292,879, dated February 5,1884. Application filed February 21, .1883. Renewed January 2, 1884. (No model.)

To all whom it may concern/r Be it known that I, JOHN WALKER, of Cleve land, in the county of Guyahogaand State of Ohio, have invented certain new and useful:

tion, ofthe' box, oil pan, and attachments. Figs. 2 and 8 are detail drawings of portions 1 of Fig. 1. Fig. 4 is an elevation, one-half in perspective, showing an end view of the frame of a hanger and a side view of a box, oil-pan,

and portions of a shaft. Fig. 5 is a vertical sectional view of a box, oil-pan, and portions of the hanger, frame, and attachments, andalso one view ofa scraper or device for scraping the oil from the shaft. Fig. 6, is a plan view of the bottom of an oil-pan, showing also thesaid scra er. Fi s. 7 and 8 are end views I: 7

showing the construction of my device.

A represents the frame of the hanger; B, the box, and G the oil-pan nearly surrounding the box. The frame is provided with a vertical cylindrical chamber, a, above and below the box, and in these chambers are placed the hollow plugs a,with their headsin contact with their respective set-screws a. The said screws and plugs are for supporting the box and adjusting it vertically. The box may be provided in the center, both above and below, with spherical projections, so placed that they shall have a commonradial center, that shall be also the center of the box. 7 The projection on the top of the box engages the open end of the top plug a, while the projection on the bottom of the box rests in a seat in the oil-pan, which'in turn has a like projection on the bot tom, that engages the open end of the lower plugs a, and thus forms, in effect, a ball-andsocket bearing for the box and oil-pan. The hangers having first been placed'in as perfect a line as practicable, it will only be necessary for the box to turn avery short distance to bring itself always in line with the shaft. It

Will be seen that in this adjustment the open ends of the cups travel over so small a portion of the said spherical projections as to be hardly said remaining portions of theprojections, en-

gaging the cups, as aforesaid, would then be in the shape of rings projecting from the box,

I prefer making this part of the device. These ring projections are marked 1), and shown more clearly in Fig. 5. The box is provided with tallow-chambers b, and also with an ori- 'fice, N, in the bottom of the box, through which, by aid of a wick,'the oil is drawn from the oil-pan below to lubricate the said box.

The raised'seat in the bottom of the oil-pan, as'shown in the plan view, Fig. 6, is not a continuous ring like the others aforesaid, but is made of segments of a ring, so placed as to leave spaces 0 between? the segments for the free passage of oil to this part, as being the lowest portion of the oil-pan, and being also the part from which the oil is drawn by the wick to supply the box above, as aforesaid.

and it is in this form of projecting rings that The plugs c are for removing oil or sediment from the pan. The oil-pan extends beyond the ends of the box, as shown in Figs. 4 and 5, so as to catch the drip of oil from said box.

Attached to each end of the oil-pan and directly'under the shaft, are scrapers (shown more clearly in Figs. 4, 5, 6, 7, and'8) for scraping the oil from the shaft, so that the oil will fall inside of the oil-pan. This device consists of a weighted handle, D, terminatingin a bent rod, that passes througha hole in the oil-pan, and is attached to the center of the arm (Z. This arm is provided at the ends with recesses suitable for attaching scrapers, as shown in the drawings. The attachments of the said rod and the said arm are madeby so tight a fit that although the parts can, be turned, yet the weighted end of the rod or handlewill remain in any position in which.

it is placed. It will be seen that the handle a D may be so placed as to press either end of the arm d and its attached scraper against the of said opening.

when in position, support andhold firm these parts of the frame, making them equally strong 1 shaft. the arm and its attached scraper shouldbe applied that will come in contact with the shaft when the shaft has a downward motion. This oil returns byits own gravity to the center of the pan, where it is again used for lubricating the box, the sediment remaining at the depressions at the bottom of which are the plugs c. It will be seen that the top half or cover of the oil-pan has an annular opening in the center, through which the top'plug a passes, so that thesaid plug rests on the box, and not on the cover of the oil-pan. This plug has an oil-hole, a, through which oil may be dis- 3 charged to a cavity in the center of the box, terminating in an oil-hole leading to the shaft below. The set-screws a are for holding and adjusting laterally the said hollow plugs.

The frame, as shown in Figs. 1 and 2, is made with a cross-sectional opening inone side large enough for passing a shaft in or out of the hanger. This opening is provided witha block, A, that is secured by a bolt passing through the said block, and also through suitable lugs attached to the frame on each side The said block and bolt,

with the other parts. By removingthis block and bolt, the shaft may be taken out of the hanger without removing the pulleys, collars, couplings, or anything, in fact, from the shaft. The block A may be provided with an arm suitable for supporting any desired belt-shifting device. This arm may be made hollow, as shown at G, Fig. 2, inclosing an extensionarm, g, secured by the set-screw g, by means of which the belt-shifting device may be adjusted to the size of the pulley .used.

Figs. 9, 10, 11, 12, and 13 illustrate the process by which the frames for these hangers are made.

Fig. 9 represents a pattern for the hangerframe,with the eore-prints M attached, ready for making a mold for casting the said frames. The blocks A are first made with a lip, a, above and below, as shown in Figs. 12 and 13, and with a hole, as shown by the dotted lines. A core is inserted in the hole and projecting on each side, as. shown in Fig. 11, and in this condition it is laid in the mold with the line x x of Fig. 11 coincident with the line w w of Fig. 9'. After placing cores in the prints M, the mold is completed and the castings made.

.After the casting is sufficiently cool, the block A is driven out, leaving that side of the frame as shown in Fig. 10. The lips n will have formed recesses in the lugs of the frame, that will serve as guides to the block A when it is desired to place it again in the frame.

It will be seen that 'the core placed in the block A, as aforesaid, and extending through the lugs 011 either side will make a straight hole fora bolt without reaming or expending other labor upon it.

' Blocks with arms, as at G, maybe snbsti- To secure the best result, that end of having one of its sides divided, of the block secured in the opening thus formed by abolt, and provided with an extension-arm for supporting the belt-shifting or other device, and capable of being adjusted lengthwise, substantially as shown and described.

2. The combination, with a shaft-hanger having one of its sides divided, of theblock secured in the opening thus formed by a bolt, and provided with a hollow outer arm, and the inner arm fitting therein and adapted to be longitudinally adjusted, substantially as and for the purpose described.

3. In a shaft-hanger, the oil-pan having a boss resting on a Vertically-adjustable tubular seat below, the oil-box having a ring-like proj ection on its under side, adapted to rest upon the inner side of said boss, the upper side of the box being provided with a support, and the pan adapted to fit around said support, whereby the box and the pan may adjust themselves to the line of the shaft, substantially as described.

4E. The combination, in a shaft-hanger, of the oilpan, constructed, substantially as described, with the journal-box located within the same,having a ring-like projection adapted to be supported by the pan, and the pan constructed in a cylindrical form, whereby the box is inclosed, substantially as described.

5. The combination, in a shaft-hanger, of a cylindricallike oil pan, and an inclosed journalbox having a ring like projection adapted to be supported by the pan, with a scraper constructed to normally bear against the shaft and scrape the oil therefrom, substantially as described.

6. The combination, with the weighted handle D, terminating in a bent rod, of the-arm d, .so arranged that either end of the said arm or its attached scraper may be applied to the shaft, substantially as described, and for the purpose set forth.

In testimony whereof I sign this specification,i.n the presence of two witnesses,this 13th day of February, 1883.

JOHN \VALKER.
