To (ZZZ whom it may concern:

Be it known that we, MARTIN M. Heisman and AUGUST G. Nrmmcitizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lubricators, of which the followingis a specification.

Our invention relates lubricator-s especially. adapted for use on' elevators, and has forits object the provision of an improved device of this character which is of simple construction and eflicient in operation. c

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure 1 is a side view shown partially in section of a lubricator embodying the invention, and shown in position of use, Fig. 2 is an enlarged vertical section of said lubricator, Fig. 3 is a top plan view of the lubricator with the cover removed, and Fig. 4 is a partial section taken on line m-a-, of Fig. 3.

The preferred form of construction as illustrated in the drawing comprises an oil receptacle 1 which is made substantially U- shaped in horizontal section so as to provide a recess 2 adapted to receive the ordinary guide rail 3 of an elevator construction. The receptacle 1 is provided at its back with a socket 4L and a set screw 5 by means of which it may be secured to a rod or pin 6 secured on the elevator car in any usual or desired manner.

The walls of receptacle 1 surrounding recess 2 are extended upwardly at their upper ends 7 somewhat beyond the remaining walls of said receptacle and each of these upwardly extending wall portions 1s provided with a slot or opening 8 adapted to permit the passage of a wick 9 therethrough. Each of the wicks 9 is preferably folded as indicated in Figs. 2 and 3. Set screws 10 are passed downwardly through wall portions 7 in position to engage the protruding ends of wicks 9 and thus serve as means for anchoring said wicks in position and also adjusting said wicks so that the ends thereof will contact with the sides of guide rail 3 to supply oil thereto.

ceptacle fl is provided with an upwardly swmgingcover 11 which has the same genoral/shape as said receptacle and is mounted to swing upon a pivot pin 1.2 at the rear of the receptacle. Pivot 'pin 12 carries springs '13 and 14 arranged to hold said cover normally in closed position.

In use the receptacle 1 issupplied with ,asuitable quantity of oil and the wicks 9 adjusted so that their ends will contact with guide rail 3. in motion there is a certain frictional or suctional action on the oil in the wick which tends to induce feeding of said oil and to assist the capillary attraction of the wick to supply oil to the guide rail 3. Thus the wick will only feed oil during motion of the car and consequently will not drip oil when the car is stationary or not in use. The action of the lubricator isentirely noiseless and no springs or delicate parts are employed which might readily be "come out of order. Thewicks are rendered adjustable to insure proper action thereof and to compensate for any wear and. the spring held cover will exclude all dust and grit from the oil chamber. It will also be observed that in the construction set forth there'are no exposed or open parts to accu mulate dust and grit.

While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and modification without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of construction set. forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.

Having described our invention what we claim as new and desire to secure by Letters Patent is: i

1. A lubricator comprising an oil receptacle having a recess therein adapted to receive a guide rail, there being openings through the'walls of said receptacle; and wicks suspended in the receptacle with their ends protruding through said openings and adapted to contact endwise with a guide rail Thus when the car is wicks suspended in the receptacle with their ends protruding through said openings, substantially as described.

3. A lubrica-tor comprising an oil recep through the walls of said receptacle leading into the upper portion of said recess; a spring held cover for said, receptacle; wicks suspended in the 'reccptaclewith their ends protruding through said openings; and screws securing the upper ends of said wicks in said openings, substantially as de scribed.

' In testimony whereof we have signed our names to this specification in the of two subscribing witnesses.
