CABLE-RAILROAD Sl-l EAVE.

SPECIFICATION forming part. of Letters Patent No. 399,035, dated March 5, 1889.

Application filed June 9, 1888. Serial No. 276,600. (No modela To all whom it may concern.;

Be it known that i, WORCESTER Ilanooon, a citizen of the United States, and aresident of Cincinnati, in the county of Hamilton, State of Ohio, have invented Certain new and useful Improvements in Cable Railroad Sheaves, of Whieh the following,` is a specification.

The object of my invention is to so Construct a cable sheave and attaehments that said sheave may be readily and quickly oiled without removal from the Conduit, and yet admit of the same being removed for repairs, if so desired.

ln the drawings accompanying this speeitication and .forming a part thereof, Figure l is a central vertical oross-seetion through the sheave and set-Coll ars, showin g one preferable mode of attael'iing said collars to the shaft. Figz is a viewin side elevation of the sheave, the semieireular dotted lines at thebottoin of the shaft showing the position of the oil-res ervoir therein, also showing the top of one end of the shaft eut away when said shaft is keyed to the journal-box in the conduit. Fig. 3 is a vertical cross-section taken through the bottom and side Walls of the conduit and man hole and the slot-rails, showing the 4 the set-screws d, as shown.

sheave with attachments in position in said conduit. Fig. l is a View in elevation, on an enlarged scale, of the collar shown at left hand in Fig. 3, said collar being provided with an oiling` attachment. Fig. 5 is a view in'elevat-ion of the collar shown at right hand in Fig. 3, showing an airvent therein. Fig'. 6 is a Cross-section of the journal-box 'shown at left hand in Fig. 3, in which one end of the shaft is keyed.

Vhile my invention is preferably used in connection with a conduit constructed Substantially as shown, the sheave and atta-ehinents may be used in connection with any forni or construction of Conduit that will adinit of attachment of journal boxes or supports for the shaft to rest in.

The forni of conduitshown (partially) in Fig. 8 forms the subject-matter of a separate application for Letters Patent, Serial No. 277,914.

Any desirable form of sheave may be employed having one or more grooves for the eable to operate in, and is preferably east with a central hub, A, eireular at eaeh end on its outer surface. The eireular end. portions of the hub rotate in the flanged portions of the Collars, as shown in Fig.

The inner fac-e of the hub A is provided with suitable bushing, a, made fast thereto to afford a more durable bearing-surface.

The sheaye is supported by and rotates upon the shaft D, which latter is rigidly attaehed to the side walls of the conduit and man-hole in any suitable manner, one mode being shown as follows: To one side of the conduit is formed a journal-box, H, the opening` of which is i-*ertieally oblong to admit of the shaft being, placed therein at an angle. At the opposite side of the Conduit, near the bottom of the man-hole, is formed the journal-box I, which is open at top to admit of the shaft being` dropped therein. The shaft is prevented from rotatingl by means of thekey e', which is driven into the openings in the journal-box over the fiat portion d of the shaft D.

To properly,T adjust and oil the sheave on the shaft, l have provided the two set-Collars B and C, which are attached to the shaft in any suitable manner, preferably by means of The collars have east with them the eiroular flanges and o, respectively, which overlap the eireular end portions of the hub A, to prevent any dirt from Working-.in between the bushing of the hub and the shaft. The Washers e, interposed between the ends of the hub and the Collars, also assist to keep any dirt from Working in onto the shaft, and also very greatly assist to prevent rattling or any to-and-fro motion of the sheave on the shaft. The collars can be readily adjusted to take up any Wear on the Washers. y

The collar B has an air-vent, bf, made in it for the purpose of admitting air to the oilreservoir E in the shaft to secure a ready flow of oil therein.

The collar C has an inner circular recess, c', as shown in Fig. l, whieh eneireles the shaft at one end of the semieireular oil-groove E. To this collar is east the hollow lug` F, the opening f in said lug` Connecting with the eireular recess o of the Collar. To ihislugF ICO is connected the pipe G, which latter preferA ably extends up to near the top of the manhole and is covered with a suitable cap, as g. Then desired to oil the sheavc, the cap g is removed and the oil poured into 'pipe G, and from thence the oil flows into opening f', through the recess c', into the oil-reservoir .E in the under surface of the shaft.

If desired, the pipe G and cap q(/ may be dispensed with and the oil poured direct into the opening of lug F.

The shaft D, upon which the sheave rotates, has a semicireular longitudinal groove, E, in its under face, nf'hich serves as a reservoir for the oil. This reservoir being at all times filled with oil, and the sheave rotating around the saine, serves to keep the bushin of the sheave and the shaft perfectly oiled.

The operation of my device .is very accurate and reliable. It is simple in construction and affords a very convenient and cconomic means of oiling the sheaves without removal from the conduit, which feature is a very desirable one, and is quite a saving' of time and money, especially on cable lines of any considerable length. The sheave and attachments are placed together in an operative position before being placed in thc conduit, To place them in position in the conduit, the lid L of the man-hole is removed and the shaft of the sheave 'placed in the journaleboxes H and I, in the manner aforedcscribed. The key 'i is then driven to place in the j ournal box I overthe flat portion Cl of the shaft, thus retaining the shaft 'firmly in the conduit in a non-,rotatable position.

lVhen desired to remove the sheave for repairs, all that is necessary is simply to drive the key i from place, when said sheave may be lifted from place through thc man-hole in the conduit.

Vhat I'claim as new, and desire to secure by Letters Patent, isM

l. In combination with a cable sheave, a stationary shaft having a longitudinal oil-reservoir in its under or lower face, the collars B and C, attached to said shaft, the collar B, having an air-vent therein, and the collar C, constructed, substantially as described, t'or adshaft D, having a longitudinal oil-reservoirtherein, collais B and C, having overlapping flanges l) and c, respectively encircling the end portions of the hub A, the collar B, having an air-vent therein, and the collar C,.hav ing an annular recess, c', on its inner portion,
