I Application led July 13, 1 885. Serial No. 171,491. (No model.)

To all whom it may concern.-

Beit known that I, IsAAC R. MCNARY, of New York, in the county of New York and State of New York, a citizen of the United States, have invented a new and useful Improvement in Oil-Cups, of which the following is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a partof this specication, in

explaining its nature.

The invention relates especially to a device for oiling or lubricating the crank-pins and journals of marine and other engines, and it is an improvement upon the invention described in Letters Patent No. 127,205, granted .1I gseph H. Wilkinson, assigner, dated May 28,

In an oil-cup or lubricating device adapted especially for oiling or lubricating crank'pin journals, or other movable j ournals of a similar character, it is desirable to support the lubricating material by a strap or band adapted to receive the lubricating material from a cup or reservoir, and to hold it or sustain it until it is wiped off or removed by the contact of the crank-pin journal or any similar moving part of the engine therewith. It is also very essential that this strap yor. band be vertically adjustable in relation to the crank-pin journal or part oiled, and vthat the means for providing it with such adjustment be so organized and arrangedthat the adjustment may take place while the engine is in operation. It is further necessary to provide an adjustment of an exact and delicate character, that the vertical position of the delivery-surface of the strap or band may be very slightly and easily varied; and I have ascertained, that this adjustment can be obtained by varying the degree of tension upon the band or strap, a tight or fairly tight tension serving to slightly elevate the under or delivery surface, andv a loose tension, or none at all, allowing it to drop or sag to a lower level, and by changing or varying the degree of the tension upon the strap or band the level of the delivery-surface between these two extremes may be infinitely varied. This adjustment is especially important where it is desired to obtain a very ne or delicate variation of the delivery-surface of the band or strap in relation to the part of the machine oiled.

The invention further relates to means for adjusting the vertical position of the belt or strap holding mechanism or device in relation to the oil-cup. This is more especially adapted yfor use in rst locating the lubricating device in proper position, but after itis so placed the position of the belt or strap is varied, as above described.

The invention also relates to various details of construction, which will hereinafter be more fully described.

Referring to the drawings, Figure l is a vertical central section of my improved lubricator. Fig. 2 is a view in horizontal section upon the line x x of Fig. l, and in plan below said line. Figs. 8, 4, 5, and 6 illustrate modi- .Iied forms of supporting the lubricating belt orband, hereinafter especially referred to.

A represents a bracket or support, which has attached to'it or carries an oil cup or reservoir of any suitable form or variety, and adapted to deliver lubricating material in drops, as hereinafter specified. The kind which I have represented is one made by the Seibert Cylinder Oil Cup Company, of Boston, Massachusetts.

Al represents this cup or reservoir. It is secured to the bracket A by means of the screw standard or stem a and a jam-nut, a', having the nozzle a2, from which the oil or lubricant is dropped. Of course the cup or reservoir has means for controlling the delivery of the lubricant. There isattached to the bracket A, by means of the screw standards or stems B B', the belt-supporting frame or plate C. These standards are vertically movable upon the bracket, and are fastened in place by the jam-nuts c. The frame or plate C has its end c curved or bent downward to provide a support for the end d of the4 strap, band, or belt D, which is fastened thereto by sewing, riveting, or in any other desirable able belt-support e, and the latter for the retension of the spring.

ception of the spindle e', which is attached to the movable beltsupport e, at e2, in a manner to permit its revolution therein, and has the screw es, which passes into the nut G3, and by means of which the support is made movable horizontally upon the plate or support O. The portion eL of this movable support is curved, as represented in Fig. 1, and there is secured thereto, by riveting or in any other desirable way, the end d of the strap, belt, or band D. It will be seen that by means of this movable support and the screw the belt is properly carried or held, and can beY submitted to any desired degree of tension, and the movable plate can be locked in place by means of the jam-nut e5 upon the spindle e', so that the oscillation of the engine will not loosen the operating-screw, The plate C is perforated to provide a way, c4, for the passage of the lubricant from the nozzle to the band or belt, and it preferably has the cup c5 above and about the perforation c4 formed by the disk c, having the upwardfextending section c7, and the space or chamber eS below the under surface formed in the nozzle-piece cg, and these pieces or parts are secured to the plate or support C in any desired way. The space c8 is adapted to hold or support porous material of any suitable character, like felt, lamp-wick, &c., for retarding and equalizing the iiow or passage of the oil. And there may also be arranged above it, to be held in place by the disk c, the wire-gauze el", which acts as a strainer, and also to hold the absorbent in place. rlhe wall of the disk extends above the wire-gauze and serves to prevent the oil from spreading therefrom laterally upon the plate.

The belt or disk may be made of wire-gauze, perforated metal, or any suitable brous or porous material, and I prefer woven lampwick padded with horse-hair; but of course I do not confine myself to the belt or band of this description or construction. It supports upon its upper surface the disk d2, which has the wall da, and which is centrally located in relation to the nozzle; and there preferably is also arranged between the plate C and-theA belt or band a spring, F, which surrounds the exterior ofthe nozzle-piece cs at its upper end, and the lower end of which extends into the disk-space d. y Its object is to hold the belt or band away from the plate or support C and to somewhat sustain and re-enforce it. Of course a spring of any desirable size or strength may be used, so that the position ofthe belt or band in relation to the nozzle or plate may be varied as desired, and of course the screw-spindle or stud c may be used for governing or regulating the position of the operative portion of the belt, when such spring is used, so as to vary its position andalso the In operation the oil or other lubricating material is fed from the oilcup or reservoir through the nozzle, preferably in the form of drops, and the drop falls upon the wire-gauze, passes through the absorbent, and then drops from the nozzle-'piece es upon the belt or strap or band, which receives and holds it and delivers it to the crank-.pin journal or other moving part brought in contact therewith.

I would here say that I do not confine myself to the especial means herein described for providing a belt, strap, or band support with vertical adjustment in relation to the nozzle, as any mechanical equivalent for the screwposts used maybe employed. I would also say that the wire-gauze and absorbent may be dispensed with, if desired, and the plate C have simply a hole for'the discharge of the lubricant. I would also say that the spring may be omitted in certain instances, and that I may use any mechanical equivalent for obtaining the effects herein described, and also for providing the strap, belt, or band with tension. It will be `seen that this construction is simple and cheap, and that it is very useful -in that it enables slight movements or adj ustment of the oiling-surface to the crank-pin journal or thing to be lubricated to be obtained; also that the belt or baud is so held that upon each movement or revolution the journal or thing to be oiled must be brought in contact with the oil or lubricant delivery surface, and that the position of the belt or band may be so varied in relation to the part to be oiled that it may be struck thereby'with greater or less pressure or force, thereby receiving more or less lubrication or lubricating material, as may be required.

The two devices shown respectively in Figs. 3, 4, 5, and 6 are adapted tobe secured directly to the nozzle orscreW-stem of the lubricator by means of a nut or sleeve.

In Figs. 3 and 4 I have shown as a device for adjusting the strap or band the metal piece or block G, to which one end of the band is fastened, and the screw g. This piece or block is arranged to travel upon the pins or studs g, which project horizontally from thev curved end of the plate.

In Figs. 5 and 6 I have shown another construction for adjusting the strap, be1t, or band. The plate in this case is made of curved spring-arms, which are stretched or brought together by means of the screw-spindle g, one end of which has bearings at g3 in one arm,

and the other of which passes through the end g* in the other arm; and by turning the screw-spindle it will be seen that the belt or band, which is secured at each end to the ends of the two arms, is tightened or slackened as may be required and its elevationvaried.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. The combination of the belt-support C, the strap, band, or belt D, the movable plate e, the screw-spindle e, and nut c3, all substantially as and for the purposes described;
