Patented June 30, 1931 EDWARD ROSELL MCKINZIE, OI MEMPHIS, TENNESSEE ELEVATOR LUBRICATOR Application filed August 19, 1929.

My invention relates to lubricators for the guide rails of elevators or other devices wherein a reciprocating element moves to and fro along a guiding member, and it is an object of the invention to provide a device of this character which will automatically advance a lubricating stick into engagement with the guide rail and apply the same in a smooth, even manner to the sides and edge of the guide rail.

It is a further object of the invention to provide a simplified device of this character which is positive and uniform in its operation and one not only in which easy and quick access may be had to the lubricant-containing chamber without removal of any of the parts, but a device of this character which permits the forward or reverse movement of the lubricant-advancing means, affording easy adjustment for the parts, all as will be hereinafter more particularly described and claimed.

In the drawings:

Fig. 1 is a side elevation, illustrating one application of my invention.

Fig. 3, a top plan view with the cover opened.

Fig. 4, an end elevation, and

Fig. 5, a section on the line 55 of Fig. 2.

30 In the drawings reference character 10 indicates a guide rail for an elevator which cooperates with a member not shown for causing an elevator to travel in its proper path. On the elevator 11 is mounted a bracket 12 which forms a support for a spacing bracket 13 upon which my device is secured by fastening bolts 14.

My device comprises a body 15 of hollow construction for the reception of a stick of lubricant 16, and, in order to afford easy access to the lubricant, a pivoted top or cover 17 is provided being adapted to be secured in closed position by a wing screw 18. Beneath the body or lubricant casing 15 are formed, adjacent opposite ends of the same, integral lugs or bosses 19 in which is journaled a threaded shaft 20. A slot 21 is formed in the bottom of the lubricant casing 15 through which extends a reciprocable follower having its lower extremity threaded by engaging the Serial No. 386,886.

shaft and carrying at its upper end a spring 22 having a head 23 adapted to engage the end of the lubricant stick by means of which, when the shaft is rotated in a cont-raclockwise direction, the lubricant stick will be advanced toward the guide rail 10. The follower comprises a pair of crossed levers 24 and 25 pivoted together at 26 and having their upper ends held in spaced relation by means of a spring 27, the lower ends of said levers being provided with cooperating threaded sections which encircle the threaded shaft 20. it-h this construction the upper ends of the levers may be pressed together against the action of the spring for separating the-interdigitating portions of the levers and shaft 20 to permit the follower to be shifted longitudinally of said shaft to the proper adjusted position.

Means is provided for rotating the shaft 20 tomove the follower longitudinally of the same for advancing the lubricant stick, and

said means comprises a ratchet 28 fixed on said shaft and adapted tobe engaged by a pawl 29 supported between a pair of arms 30 rotatively journaled' at each side of the ratchet wheel. The arms 30 and pawl 29 pivoted therebetween upon the bolt 31 are adapted to be actuated by a link 32' having the reduced end of an oscillating bar loosely journaled therein. The oscillating bar 33"is pivotedly mounted in a bracket 34 and it extends through a guide 35 and has its rear end offset at 86 and terminates beyond the end of the body 15 in substantially parallel relation to the guide rail 10, a roller 37 being rotatably mounted upon the end of the bar and isadapt'ed to ride against a bracket 38 and be moved thereby toward the guide rail 10, thereby oscillating the bar 33andcarrying the pawl in a clockwise direction around the ratchet wheel 28. \Vhen the roller 37 moves out of engagement with the bracket 38 the pawl is caused to rotate the ratchet wheel under the influence of a. spring 39 which has one end connected to the bar 33 and its opposite end connected to a fixed portion of the end of the member 15 which will rotate the shaft 20 and advance the followeras previously described.

ratchet wheel from moving in the reverse direction, a lever 40 is fixed to the boss 19 and resiliently engages the periphery of the ratchet wheel.

It will be understood from the above description that'I have provided a lubricantcontaining casing to which easy access may be had for renewing the lubricant stick and the adjustment of the follower may be easily made with the consumption of no great amount of time and as the device inits reciprocating movement with the elevator or other structure upon which it is carried engages the stationary bracket 38 an automatic advancing of the lubricant stick will be effected and the lubricant will be fed through the end of the casing and channels 41 in the sides of the device upon the edge and sides of the guide rail 10, resulting in a thorough lubrication I of the engaging surfaces.

It Will be noted that the lateral channels have their faces remote from the guide rail 10 located at a very small angle or inclination with reference to the adjacent face of the rail. This has been found effective in securing adequate lubrication without waste of lubricant, as it spreads the lubricant out in a thin layer over the face of the guide, while the bulk of the stick is held back by the flat face of the guide against which the stick rests and this is animportant feature of my invention.

It will be obvious to those skilled in the art that various other modi'fications' may be made in my device without departing from the spirit of my invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as set forth in the appended claim.

I claim:

An elevator guide lubricator adapted to be mounted upon a reciprocating member and comprising a hollow casing provided with a slot in one end for receiving the member to be lubricated, tapered lubricant passages extending from the interior of the casing along the sides of the slot, a removable cover 7 for said casing, a follower in said casingfor advancing a lubricant stick, a slot in said casing, a threaded shaft j ournaled inparallel re lation to the slot in the casing, aisplit nut on said shaft having operating means projecting through the last-named slot into the casing and engaging the follower, and automatic means for rotating said shaft.

In testimony whereof I affix my signature EDWARD ROSELL MoKINZIE.
