. .To all ivhom 'it .may concern:

Be it known that I, OWEN T. SNxDEIi,-a citizen 'ofthe UnitedStates, residing at Columbus, vin the county of I `-1a11kli'n aud' State of Ohio, have-invented a certainneiv and useful Improvement in Lubricators for Elevator-Guides, of which the followingl is a specification.

The object of this invention is'to provide a lubricator more especially for the'guides of elevators said lubricator being of simplified and improvedconstruction and adapted 'to effect an economy of the lubricant; and

also prolnote cleanliness.

The invention is embodied in the example shown in the accompanying .drawing and portion ofthe-Oil lbox in section.

set forthv in the following description, the featuresofnovelty Vbeing pointed out in the appended claims. t i

In the said drawings Figure l is mainly a vertical elevation ofthe oil distributing end of the device, one side being partly in section to illustrate interior details. Fig. 2 is a top plan view showing the devicel associated with an elevator guide, lthe latter being shownjin' horizontal section. -Fig 3 is a view in side elevation Withtheupper In this view -there isalso shown a fraction of the elevator carriage and guide rail.' VFig. 4 is -a detail viewon a., magnied scale of the uick holder with portions of the construction in section.

In the vietvs 5 designates the box to contain the Oil as shown,vsaid box being recessedin 011e of its vertical sidesv as seen at 5a to extend around three sides of the usual j guide rail 6. (See Fig. 2.)

7 is a stripfof spring metal bent at its upper end to extend over the upper edge of the Wall of the box. This spring is secured at its upper end bya screw 7? tapped into a projection 5b cast with kthe box. Secured by means of a rivet 8a to the outer or lower end` of the spring 7 is a block or piece 8 of imperv-ious or non-absorbent material as for example liard fiber, or compressed paper pulp such as is noW common on the market. Secured 4by the same rivet 8L tothe spring 7 is also a strip of lamp Wick 9 Which extends upward over the face of the springv and the upper edge of the box into the interior of the latter andthe Oil therein. The block 8 is recessed Where l the Wick fits I speia'catidn'of-Letteis Patent.

the-reto .the spring 7 can be bent suitably, as

seen at. 7c so that the face of the block shall standvvertical when held Vout by the guide. There are three of these lubricating Wicks andthe described holders therefor. -They are held in place'by small set screws as seen at 10.' The springs 7 are so formed that the blocks bearvivith a light pressure on the rail when the box is applied thereto.

ldesignates a disk opposite projection 5b to bear upon the Wick to control the flow of oil. The pressure of this disk is regulated by a' screw in the wall of the box.` l*

The' Oil .boxl is shown as provided with a A cover at l1 hmged` to the. rear edge ofthe"A box as at 12, 12.` The box is secured to the elevator carriage on a rod 13 secured'at its lfoot'loy means ofa bolt 14 and nut 15a. The

box 1s secured on the rod 'by means of 'set screw 16 passed through a lug15c on thel box.. As the'box .traverses the guide the oil is drawn by capillary attraction through the ivick up over the Wall of the box and down to 'supplythe face of block 8. The block 8 is of little or practically no absorptive capacity and as it becomes dry fresh Oil is supplied by the Wick. Not only does this construction economize the oil but italso Wears Well because of the hard nature of the block.

That I claim is:

l. In a lubricator of the kind described, the combination with an oil box or reservoir, of a spring consisting of a strip of spring metal secured Vat its upper end to the upper portion of the box, said spring containing at .its lower end ablock of nonabsorptive material to be yieldingly held by the springagainst the part to be lubricated, anda Wickextending from the interior of the box over and adjacent to said spring and to said block. p

2. In a ilubricator ofthe kind described, the combination with an oil box or reservoir, Of a` spring consisting of a strip of spring metal secured atits upper end t-o the upper portion of the box, said spring containing at its lower end a block of nonabsorptive material and a recess to receive :the wick, said block to be yieldingly held by the spring against the part to be lubri-. cated, and a Wiek'extending from the interior of the box over and adjacent to said spring and into .the recess of said block.

3. In a lubricator of the kind described-7 the combination with an voil box or reser- 4Voir, of 'a spring bearmgat its lower end a' block of non-absorptive material and a Wick tially flush with the face of the block.
