, LUBRIGATING DEVICE.

To all whom it may concern:

Be it'known that I, AUGUST F. KIRSCH- BAUM, a citizen of the United States, residinguat St. Paul, in the county of- Ramsey and State of Minnesota, have invented cer-' tain new and useful Improvements in Lu 1 bricating Devices, of which the following is larly to provide an improved device for.voil-' ing the guideways for elevators and for equivalent uses, and to this end consists in the features of construction, combination,

a specification.

My invention relates to improvements-in lubricating devices, its object being-particuand arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure 1 is a top view of my improved device shown in connectionwith an elevatorguideway; Fig. 2 is a side elevation of the same partly broken away; Fig. 3 is a front elevation shown sectioned on line w-m of Fig. 1; and Fig. A is a detail view of an actuating lever forming part of the invention.

Referring to the drawings A represents a receptacle for the oil provided with a suit able cover 2, the receptacle being supported upon the elevator B as by means of brackets 3. The elevator forming no part of my invention is only shown fragmentarily. Leading from the bottom of the receptacle is a downwardly extending conduit plug 4 tapped into which is a laterally and downwardly extending tube 5. constituting a discharge conduit for the oil. Slidable in the tube 5 is a plunger 6, normally held outward by acoil spring 7 arranged within the tube and interposed between the plunger and conduit closing plug 8.. The plunger 6 is loose within the pipe 5 to allow oil to pass over it, the free end of the plunger wiping the guideway 9 to deposit the 011 thereon. conduit is closed by a valve formed by the lower end of the rod 10, said rod at its upper end having ivotal connection 11 with the outer end 0 a link 12. supported on a transverse rod 13 journaled in the sides of the receptacle. The rod 13 is normally held in position closing the valve by means of a spring 14: connecting one end of the rod with the receptacle. Secured upon the opposite end of the rod is an arm 15, said arm at its free end pivotally supporting an extensionarm 16 through the medium of a Specification of Letters Patent.

pivot 17. The extension arm 16 is normally I held in alinement with the supporting arm 15 by means of a lateral finger 18 carried by the inner end of the extension arm, the finger 18 being normally held in contact with the underside of the arm 15 by the overweighted outer end of the extension arm. The outer end of the extension arm is thus free to swing upwardly but is held against swinging downwardly. A stop 19 is positioned at a suitable point along the guideway to engage with the extension arm, as indicated in Fig. 1. v In use, the elevator as it travels upwardly upon the guideway, carrying with it the lubricant reservoir, will cause the free end of the extension arm 16 to beobrought into contact with the stop 19. As the elevator continues to travel upward the engagement of the stop 19 with the. arm 16 will, through the intermediate mechanism, lift the valve 10 and allow a certain quantity of oil to pass downwardly through the discharge tube around the plunger 6, the oil being wiped upon the guideway by the plunger. As the extension. arm 16 is carried past the stop 19 the parts will berestored to normal position by the spring 1 1. In the downward travel of the elevator, the engagement of the stop 19 with the extension arm 16 turns said arm upon its pivot without affecting the normal position of the parts. Any desired number of the stops 19 may be used to regulate the amount of oil discharge from the reservoir. 7 I 7 While I have shown my invention applied to an elevator for oiling the guideway, I.

In testimony whereof I afiix my signature 7 in'p resence of two itnesses.
