GHARLES r. WOLFE, or new Y'ORK,

LUBRICATOR FOR GUIDE-RAILS.

application filed October 18, 1920. Serial 110. #117,534.

To all whom itmay concern:

Be it knownthat I, CHARLES F. VVoLrE, a

citizen of the United States, residing at' New York city, in the county of New York and State of New York, have invented new and useful Improvements in Lubricators for Guide-Rails, of which the following is a specification. g

This invention relates to improvements in lubricators for the guide rails of elevators, counter weights, and the like.

The' principal object is to produce a device of this nature which shall be simple of construction, cheap to manufacture, and highly eflicient for the purpose for which it is designed.

Another object is to produce a device of this nature which may readily be adjusted to different sizes of shoes.

Another object is to-provide simple and efiicient means for securing the device to the shoe without drilling apertures in the shoe.

Another object is to provide means for indicating the amount of lubricant in the device.

With these and other objects in view which will be apparent as the specification proceeds, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described and claimed, and which are shown in the accompanying drawing, in which Figure 1 is a side elevation of my improved device as applied to elevators.

Fig. 2 is a rear elevation of the same.

Fig. 3 is a vertical sectional View on line 33 of F ig. 2. I V

Fig. 4 is a view similar to Fig. 1, but showing the device as constructed for use on the rail of a counter weight.

Like characters of reference refer to like parts in all views.

Referring to the drawing in detail, 10 rep resents the rail to be lubricated, and 11 represents the shoe traveling thereon. Two L-shaped blanks, each having a broad leg 12 and a narrower leg 13, are cut from sheet metal and each leg 12 is bent at 14. The blanks are also bent at 15 the juncture of the

legs

12 and 13 and the legs 13 are riveted together at 16. The legs 12 thereby form a square receptacle in which is inserted the candle or stick of lubricant 17, which is Specification of Letters Patent.

' relation to the rail, and

Patented Ma 7 1221- thus supported at such an an from the receptacle against t v e rail and is aided in this movement by a weight l7 secured to the tell-tal hereinafter described. A cover member 18 fits over. therear end of the legs l2'and is provided with an aperture through which passes a tell-t ale'rod 19 the inner end ofwhich carries weight 17 and lssharpened so as to pierce the rear end of the candle, so that \the rod 19 moves down with the candle and gives notice to the operator when a new supply of lubricant should be provided. The'rod 19 has an angular finger 19 which contacts with member 18 to prevent the rod or weight from contacting the rail when the lubricant is nearly exhausted.

The legs 13 are bowed outwardly and at their lower end which fit over the ends of a bolt or rod 20. The rod 20 is threaded at both ends and is provided with two pairs of nuts 21 and 22. A pair of clamping straps 23 are mounted on bolt 20, each being between one ofthe nuts 21 and the adjacent nut 22. The clamping members 23 are provided with a. plurality of apertures 24: for permittin adjustment of the bolts to accommodate different .sizes of shoes. A bolt 25 passes through members 23 between bolt 20 and the shoe.

s are provided with apertures.

le as to slide In use, the nuts 21 are screwed out until the space between members 23 is substantially the same as the thickness of the shoe 11. The free ends of member 23 are then adjusted to the sides of the shoe and bolt 25 is'tightened whichforces the free ends of members 23 into clamping contact with the shoe. The receptacle is then adjusted to position for holding the candle in proper nuts 22 are tight- 61116Cl so that the receptacle is held rigidly in ace. p In the form shown in Fig. 4, the clamping members are secured to the nuts 26 of the bolt which is used to hold the counter weights 27 together, and the

legs

12 and 13 are arranged slightly differently in relation to each other so as to adapt the device for efficient use in connection with the guide rail of the counter weight.

The candle is slightly larger than the thickness of the rail so as to effectually lubricate the sides as well as the face of the rail. Also, the candle is preferably made with a center core which is harder than the exterior portions so as to prevent too rapid wearing away of the lubricating stick.

Particular emphasis is laid upon the simplicity of construction and operation of the device.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do not. limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

hat is claimed as new is 1. A lubricator for guide rails comprising a lubricator receptacle having depending legs formed integrally with the receptacle, a pair of clamping members, a bolt for securing said legs to said members and for holding said members in spaced relation, and

means for efiecting clamping action of the free ends of said members.

2. A lubricator for guide rails comprising a plurality of 'L-shaped members secured together to form a lubricator receptacle and supporting legs, and means for securing said members in place.

3. A lubricator for guide rails comprisin a plurality of L-shaped members securei l together to form a lubricator receptacle and supporting legs, and adjustable means operable to frictionally secure said members to elements of various thicknesses.

4C. A lubricator for guide rails comprising a plurality of L'-shaped members secured together to form a lubricator receptacle and supporting legs, and a plurality of clamping members adapted to be adjustably secured to said legs and to be adjustably secured to elements of various thicknesses.

'In testimony whereof I have afiixed my signature.
