LUBRICATOR.

Specification of Letters Patent.

- Application filed November 2, 1909. Serial No. 525,854.

Patented Jan. 31, 1911.

v To all whom it may concern:

Be it known that I, NATHANAEL L. CHAL- Mm, a citizen ,of the United States, residmg at Newark, in thecounty of Essex and State of New Jersey, have mvented certain Improvements in .Lubricators', of which the following is a specification.

This invention especially relates to means for lubricating the bearings of shafts in in which'li a lubricator of my improve and more particularly the bearings of trolley cars.

The objects of theinvention are to secure a constant supply of lubricant to the hearing; to ,regu ate the amount of lubricant supplied, and to prevent more than necessary being supplied to the bearing; to thus economize lubricant, and effect a saving in expense as well as labor; to secure perfect lubrication, simply and cheaply, and to obtain other advantages and results as may be brought out in the following descri tion.

Referrin .to the accompanying rawings, e numerals of reference indicate corresponding parts in each oft-he several figures, Figure 1 is an end elevation, artly in section, of a shaft bearing rovided with d construction, said lubricator beingv an integral art of the cap of the bearin ;-Fig. 2 is a p an of-a ,lubricator constructe independently of any bearingand adapted to be applied to a hearing at pleasure, no cover for the reservoir and no cap for the wick-tube being shown, and Figs. 3 and 4 are vertical sections taken on lines 3- 3 and 4-4, respectively, of Fig. 2 with said wick-tube cap. .In said drawin s, and articularly Figs. 2, 3 and 4 thereo 10 in icates a reservoir adapted to contain lubricant and which I have shown in the. drawings as cast in one integral piece, although obviously it could be put together in any suitable and wellknown manner. Said reservoir 10 has projecting up from its floor or bottom 11 a tube 12, the 'top of which is substantially flush with the t p offthe reservoir. A wick 13 is inserted; in the said tube 12 and passed downward at the bottom. thereof through a hole 14 in the bottom of the reservoir 10,

the end 15 of the wick below the said reservoir extending as desired to the bearin which is to be lubricated, and the said'wic at the upper end of the tube 12 being bent or aperture 16 in t eir journals, such as axles and the like,-

the wick 13, and regularity.

reservoir 10, (preferably extending to theand receives the wick 13 easily,.so that the same can slide freely-therein, while above,

'the floor 11' the wick 13 is held central in the tube 12' b an annular packin 18 of waste or the ii is and which is force ti htl into place as shown in the drawings. Fre erably a little cap 19 closes the top of the tube 12, and the one I have shown in the drawing comprises a disk20 with a hollow shank 21, or flange, adapted to project into the tube, said shank or flange being slotted at one side, as at 22, to receive the wick 13.

It will be understood that the reservoir 10 is to be mounted on top of a bearing and the lower end 15 of the wick 13 extend to, or nearly to, the bearing surfaces. I have shown in the drawings a boss 23 upon the bottom of the reservoir around the wick. which facilitates the mounting of the device upon a bearing, although it is not absolutely necessary. The reservoir being filled with oil nearly to the top of the tube 12 feeds the same gradually to the bearing, through with great evenness and There is no waste of oil, and it is necessary'only to see that the reservoir 10 is kept supplie F1 In Fig. 1, I have shown a.lubricator or my improved construction applied to a bearing, and made an integralpart oi: the same, instead of separate. Here 25 mdicates the lower member of the bearing for the shaft 26 and 27 is the cap adapted to be secured by cap screws 28,. 28. My reservoir 29 is formed in the top of said cap and has the interior tube 30 with wick 31 arranged therein as previously described in connection'with the reservoir 10. The end 32 of said wick extendsdownward through a passage 33 in the cap 27 and its lining 35, if there be one, to close proximity to the shaft 26. A cover 34 is shown provided for the reservoir 29, and obviously a cover Cclan always be used if desired to keep out irt.

Having thus described the invention, what I .claim is:

'1.- A lubricator comprising a reservoir having'an aperture in its wall, a tube in said reservoir of larger bore than said aperture imperviously connected at one end to the wall of the reservoir around said aper ture and extending at its other end to the i ing a lateral recess or notch in the edge 01, upper part of the reservoir, a wick extend said last-mentioned end,'a wick extending ing through said tube and aperture with one through said aperture and tube and lateral end outside the reservoir and the other end recess or notch thereof with one end outside 20 reaching to the lower part of the reservoir the reservoir and the other reaching to the chamber, said wick fitting the aperture and lower part of the reservoir chamber, said extending centrally through the tube, and an wick fitting the aperture and lateral recess annular packing of waste or the like packed or notch and extending centrally of the tube, tightly around said wick in said tube. an annular packing of waste or the like 25 2.
