SHAFT-HANGER.

SPECIFICATION forming part.` of Letters Patent No. 278,404, dated-May 29, 1883.

Application tiled September 18. 1882. (No model.)

,To all whom it may concern:

Be it known that I, HILEN C. UROWELL, a citizen of the United States, residing at Erie, inthe county of Erie and State of Pennsylvaniamhave invented certainnew and useful Improvements in ShaftHangers; and I do hereby declare the following to be a full, clear, and exact description of the invention,.such as will enable others skilled in the art to which it ap- 1o pertains to make and use the same.

This invention relates to what are` known as shaft-hangers 5 and it consists in new and useful improvements in the construction ofthe same, which will fully appear in thefol- `1 5 lowing description and claims.

The invention is illustrated in the accompanying drawings, as follows:

" Figurel is a vertical section through the hanger on a line transversely to the shaft.

i `2o Iiiig.` 2 is a vertical section on a linelongitudinal with the shaft. Fig. 3 is a perspective view of the box. Fig. 4 is a perspective view j of one of the bearing-blocks C. Fig. 5 is a fragment of the hangerA, showing the opening for the screw D, with parts broken away,

so as to show construction.

. A is the hanger-frame; Al A', an enlargement of the frame, forming openings for the screw by which the box is adjusted vertically.

i 3io B B' is the journal-box. C C are bearingblocks, which lie between the vertical adjusting-screws and the journal-box. D Dl are the vertical adjusting-screws, and d d are the lateral adjusting-screws. i Other parts will be re- "3 5 ferred to in proper connection in the following generaldescription and claims.

The construction of the box andthe manner of adjusting it are similar to that shown in a previous application `by the present inventor;

i *40p but the construction of the screws by which the box is adjusted vertically and the devices connecting said screws with the box, and the construction of the frame to receive and operate said screws, and the means provided for lockingfsaid screws whenthe proper adjustmentis had, constitute the essential features of this invention, and are as follows:

The frame A is cast with the openings A' A' cored out, and on the inner wall of these y y '5o openings are formed in the castingscrew` threads a a on one side of the opening. These screw-threads are simply a series of lugs having the proper pitch and spaced so as to form segments ot' a screw-thread. `Un the wall op posite these lugs a a is cored "out a recess, in .55 which a bearing-plate, a', can be adjusted.` A screw, e, is tapped through the wall into this recess and operates against the bearing-plate.

The screws D Dvare quite large, and are formed of cast metal. They are made so as to 6o work easily and freely in the threaded openings A A. When they have been adjusted' so as to properly hold the box they are locked in .place by the screw e, which acts as a setscrw or jam-screw, the bearing-plate a' sim- 65 ply serving to give a larger bearing-surface, and ot' course it can be dispensed with, if desired; but its use is preferred because the screw will then not damage the thread. on the sciiews. 'Ihese screws DD swivel onto bear- 7o ing-blocks C C, which are placed between them i and the box. The bearing-surfaces of these blo'cks are curved inwardly, so as to fit upon the curved-backed bosses b b on the box and permit free lateral adjustment of the box by 75 the screws d d', and at the same time allow the box to turn vertically therein as -in a journalbox, and being swiveled in the screwsD D by the pin c', they permita horizontal pivotal movement of the box, thus forming a univer- 8o sal joint for the box.

l am aware that shaft-hangers have been provided with vertical openingsfor shaft-adjusting screws, each held in place by a setscrew having a segmental screw-thread upon 8 5 its end, which corresponds with the thread on the shaft-adjusting screw, 'but am not aware that `said openings have been provided with screw-threads which support the side of and form a bearing for the shaft-adjustin g screw 9o opposite to that in contact with the set-screw.

1. In a-shaft-hanger, the frame A, havingv openings A' -A cored therein, with screwthreads formed on the walls thereof, in combination with screws D D', set-screws e e, and the swiveled bearing-blocks `(l G.

2. In a shaft-hanger, the frame A, having openings A A' cored therein, with the segments of screw-threads eta formed therein, loroo cated above and below the shafbline, adjust?, ing-serews-D D', placed within said openings and provided with swiveled bearing-blocks C C, with inwardly-curved bearing-faces, setscrews e e, adjusted as shown with relation to said screws D D', in.goinbinabigngwighthebbox B B', having-bosses b b upon its upper and lower surface, substantially as and for the purposes set forth. i
