OILING AND ADJUSTING DEVICE FOR CABLE-SHEAVES.

SPECIFICATION forming part of Letters Patent No. 415,792, dated November 26, 1889.

Application filed March 8, 1889. Serial No. 302,504. (No model.)

T0 all tlf/72,071@ it may concern.-

Be it known that I, WILLIAn PHENIx, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in an Oiling and Adjusting Device for Cable-Sheaves, of which the following is a full, clear, and exact-description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

' The object of this invention is to provide a combined oiling and adjusting device for sheaves rotating in a horizontal position and arranged in a curved plane for the purpose of carrying or guiding traction-cables around curves.

Figure l is a vertical section of a sheave and supporting-base embodying my improved features, and Fig. 2 a plan with the sheave removed.

Referring to the drawings, A represents a sheave loosely mounted on the vertical stationary shaft or axle B. The lower end of this shaft is rigidly secured in the slide-block C, which is adjustably inserted in the stationary bed-plate or frame. D. The shaft B is provided longitudinally with the aperture or central oil-passage a, starting in from the upper end and stopping just short of the lower end and terminating in the intersecting aperture a', passing horizontally through the shaft, as shown in Fig. 2. The transverse aperture a opens into the oil chamber or reservoir D', formed in the slide-block C. The upper end of the shaft is provided with the horizontal groove a2, extending across from the vertical oil-passage to the periphery. A wick a3 is inserted in the vertical oil-passage in the shaft and in the groove a2 for the purpose of conducting the oil by capillary attraction to the sheave-bearings, and thus providing a continuous lubrication.

E represents the hub of the sheave, and a4 the bearing-box, of Babbitt Inetal or other suitable material. The hub is provided with the annular oil-pocket a5, which forms an auxiliary reservoir for the lubricant fed from above, and assists in maintaining a continuous lubrication. The lower end of the sheavehub rests on the bearing a,plaoed in the upper cupped side of the slide-block C. The lower end of the hub is also provided with the annular groove b for the reception of the vertical rim b', formed on the slide C andloosely engaging with said groove,whereby the sheave is caused to follow the adjustment of the slide.

The bed-plate D is provided with the recess h2 for the reception of the slide-block. This plate is also provided with rectangular grooves b3 b4, into which the corresponding ribs d d', formed on the slide-block, loosely iit, thus providing for the required adj ustment.

F is an adjusting-screw having a threaded engagement in the lug (l2, formed on the bedplate. The inner end of this screw bears against the end lof the slide-block, whereby said block may be adjusted to bring` the sheaves into line with reference to each other and the line of the cable, the relative position of the cable being indicated in dotted lines.

The overhanging cup-shaped cap H is removably secured to the upper end of the shaft by tap-bolts h h', and serves the purpose of excluding the dust and dirt from the oil-chamber and bearing-surfaces.

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

l. The combination of a sheave, a stationary shaft having a transverse groove in the upper end and provided longitudinally and centrally with an aperture or oil-passage starting in from the upper end and stopping short of the lower end, and the intersecting horizontal aperture opening into the oil-chamber in the slide-block, said slide-block, and the wick for conducting the oil tothe part-s to be lubricated, substantially as and for the purpose set forth.

2. The combination, with an adjustable slide-block provided interiorly with an oilchamber, of the sheave-shaft having th e lower end iixed in said slide and provided with oilpassages, as described, and the wick for conducting the oil from said chamber to the parts to be lubricated, substantially as and for the purpose set forth.

3. The combination, with avertical stat-ionary shaft, of a sheave loosely mounted thereon, the adjustable slide-block provided interiorly with an oil-chamber, said axle-shaft having oil-passages communicating with said cham- AIoo ber, the wicking for conducting the oil, and the with oil-passages comm u uieating therewith, bed-plate in which said slide is ardjustablyiu` the wicking' inserted in said oil-passages, the serted, substantially as and for Jthe purpose shezwe loosely mounted ou said shaft, and the set forth. Voverhdngiug cap removably secured to the f 5 4. The combination, with the bed-plate, of upper end of the axle-shaft, all substantially I5 a slid e-block adjustably secured iu said plate as and for the purpose set forth.

and provided interiorly with au oil-chamber, \VILLIAM PHENIX. the adjustingscrew, the shaft; having the Witnesses: lower en d rigidly fixed in said slide and pass- L. M. FREEMAN,

Iov ing through said oil-Chamber and provided J. B. DONALSON.
