GUIDE-RAIL LUBRIGATO To dllwlidntz't mayconccrnr Be itltnownlthat I, VViLLrArr P. HnGGAN, a subject of'the Kingof Great Britain, re-

siding at Victoria, in the Province of British Columbia and Dommon of Canada,.have 1nvented new and useful Improvements in Guide-Rail Lubricators, of which the followingis a specification. v

' This invention relates'to improvements n lubricating devices for elevator guide rails and the like. y

An object of the invention is to provide a lubricator which will efliciently supply W1th oil or other suitablelubricant, each working face of the guide rail.

Another object is to provide a means for independently regulating the supply of lubricant to thediflerent faces, or for cutting off the supply altogether when desired.

Another object is to so arrange and mount the distributer blocks, which conduct the oil to the rail, that they may be readily replaced when worn.

To effect these ends and such others as Wlll hereinafter appear I have incorporated the invention in the preferred form illustrated in the drawings, recited in the .claims, and set forth in detail in the specification below.

In the drawings Figure 1 is a fragmentary vertical sectlon through the lubricator as associated with a guide rail.

Fig. 2 is a transverse section on the line 22 of Fig. 1.

Fig. 3 is a top plan view. Fig. 4 is a perspective view showing in detail, one of the .distributer blocks.

The lubricator, indicated in the drawings by the numeral 1, has a receptacle or reservoir 2 for containing the lubricant, this receptacle being in the present instance sub stantially rectangular in form. In order to fill the receptacle 2 with oil, grease or other suitable lubricant, it has the upper endopened in the present instance and is provided with a lid 3, which may be secured in position by thumb screws 4. The receptacle 2 is formed in one face with a vertical channel 5 preferably rectangular and adapted for receiving a guide rail 6. An extension 7 on a convenient portion of the reservoir 2, may be formed with openings 8, for passage of bolts, or other securing means, whereby it may be attached to the elevator. The receptacle 2 is formed in the bottom 9 at a Specification of Letters Patent.v Application filed September 28, 1917. Serial No. 193,809..

5 of the channel 5, with an opening 10.

Under each opening lO', is slid-ably mounted for movement toward and away from the center of the channel 5, a distributer block 11.

In the preferred form shown, the; mountings for theblocks ll consist of downward extensions 12 of the reservoir 2, having lateral inturned flanges 13, constituting with the adjacent ways in which the blocks 11 are slidably engaged. For further retaining the blocks 11 in the. proper position, pins 14; are provided on the extensions l2 for engaging in suitable openings 15, whe'rewith the blocks 11 are formed. A spring'means fo1*.maintaini11g each block in contact with the rail 6, is here indicated as a coiled spring embracingthe pin 14;, and pressing against the block 11 and the extension 12.

The blocks 11 are preferably rectangular and each has a horizontal face disposed under a respective opening 10 and a vertical face for contact with the rail 6 disposed in parallelism to the adjacent side of the channel 5. Passages are formed in the block for conducting lubricant from the horizontal surface 17 to the vertical surface 18. Preferably, the conducting passage of each block consists of a V-shaped notch 19 in the upper surface, the lower apex of the notch 19 communicating with suitable radiating grooves 20 in the vertical surface 18.

each opening 10. a pin 21 has a tapered end extending through the opening. The pins 21, are mounted for vertical adjusting movement, this being accomplished in the present instance by screw threading each pin 21 into an opening 22 in a respective lug 23, secured on the inner wall of the reservoir toward the upper end. Each pin 21 is adapted as by formation with a slot 24 in the upper end, for application of a suitable tool whereby it may be adjusted.

In order that the blocks 11 may be readily removed for replacement, I preferably space the extensions 12 apart a sufiicient distance and form the blocks 11 of such size that they may be readily removed When the reservoir is disengaged from the rail.

I am aware that the herein described form of the invention recites only one of many possible embodiments, and reserve the right to all variatione and departures therefrom,

portions of the bottom guide- 'point somewhat outwardly from each side falling within the latitude of the invention.

reservoir formed in the bottom with a plu-' rality of openings, each of said openings in proximity to a respective face of the rail, a plurality of distributor blocks, each formed with a lubricant passage extending from one face of the block to another face of the block, and means for maintaining each block of said plurality with one of said faces in contact with said rail and the other of said faces under a respective opening of said reservoir.

2. The combination with a guide rail, of a lubricant reservoir having projecting portions partially embracing said rail, said reservoir formed in the bottom with a plurality of openings, each of said openings in proximity to a respective face of the rail, a plurality of distributer blocks, each formed with a lubricant passage extending from one face of the block to another face of the block, means for maintaining each block of said plurality with one of said faces in contact with said rail and the other of said faces under a respective opening of said IBSGI'VOII'.

3. In a lubricator, a reservoir provided in one side with a vertical channel, and formed in the bottom adjacent each side of the chan nel with an opening, said reservoir having a lug on the inner wall over each opening, a pin screw threaded into each lug, each pin provided with a tapered end in the respective opening, a downward extension on the bottom of said reservoir outwardly from each opening, a horizontal pin on each extension, a block on each pin having a horizontal face under a respective opening and a vertical face disposed in a plane parallel to the respective side of the channel, each block formed with grooves adapted for conducting lubricant from the horizontal face, and spring means pressing said blocks toward the center of the channel.

In testimony whereof I afiix my signature.
