T0 @ZZ whom t may concern.'

.Be it known that I, JAMES T. HAYDEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Cups, which are fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l represents avertical section of an oil-cup containing my improvements; Fig. 2, a plan section of the same, taken on the line 1 l, looking in the direction of the arrows 2 2; Fig. 8, a section on the same line, looking in the direction of the arrows 3 3; and Fig. 4, a detail perspective of the lifting-cam and cap detached and on a smaller scale than the other figures. f

My invention relates to oil-cups designed to automatically lubricate journal-bearings and other like parts where friction is occasioned by one surface moving upon another.

The invention relates to certain improvements in the devices for regulating the feed from the oil-cup and to provide for filling the cup whenever required.

I will proceed to describe in detail the construction and operation of an oilcup embodying my invention in practical form, and will then point out definitely in claims the special improvements which I believe to be new and wish to secure by Letters Patent.

In the drawings, A represents the base of the cup, which is constructed much as usual, being provided with a stem a at its lower end externally threaded, by means of 4which the cup is secured wherever applied, and having a duct a bored upward through the stem and nearly through the base. The central tube A', which is usually a separate piece, I make in one piece with the base, from which it rises centrally, as shown in Figi of the drawings. This tube'is threaded externally upon its upper end and is bored its entire length,thus forming a central passage d2 eX- tending nearly to the duet a in the base, and communication between these two is provided by means of a small aperture a3, leading from one to the other. Near the base of the tubular projection A side apertures a4 are bored into the central passage, so that oil may pass through them in to the latter, and thence down through the feed-aperture a5 and the duct et lto the part which is to be lubricated.

The head B is provided with a central depending circular flange b, which is threaded internally and adapted to be turned upon the upper end of the central tube A thereby providing for securing these two parts together and so fastening between them the body C, which is usually of glass, the base and head being of ordinary construction to adapt them to this purpose. From the upper side of the head B rises a neck b', which is tubular and opens down through the head to the interior of the circular flange below. This neck is covered at the top or upper end and through the cover is an angular opening b2. When the base and head are fastened together with the body C between them, as seen in Fig. l of the drawings, it is evident that a circular chamber will be provided within the neck of the head and extending from its cover to the upper end of the central tube A. The head B is also provided at one side with an opening b3, through which the cup may be filled.

On the top of the head B is mounted a lifting-cam D. This piece is in the nature of a circular thimble, Vwhich iits down over the neck of the head and is free to turn around said neck. The top of this piece has a central opening d, which corresponds with the opening in the top of the neck below, and at the outer and upper edge of this thimblepiece is a slight flange d projecting upward. Notches d2 are cut in this flange opposite to each other, and the ends of the flange-sections at these notches are made, respectively, with vertical and inclined faces, as seen at di d4 in Fig. 4 of the drawings. At its lower end this lthimble is spread out to make a base d5, nearly covering the head, uponwhich it rests, inwhich is cut an opening d, which is arranged to reg ister with the filling-opening in the head below when this piece is turned into proper position. A short handle d7 extends outward at one side from this base, by which this piece may be turned about the neck over which it is placed.

The spindle E is providedat its lower end witha round section e, adapted tot the open-k ing iii the tube A. .Iust above is an enlarged ring or collar c, above which is an angular section e2, which extends iiearlyto the upper end of the spindle, the extreme upper end, however, being a threaded section c3. i The spindle is arranged as shown in Fig. l of the drawings, the angular section being of the same shape and adapted to` iit the angular opening in the top of the neck, through which it passes up through the circular opening in the top of the ihinihle, which is large enou gli to accommodate the spindle in this arrangement. A spiral spring Fis arranged around the spindle inside the neck of the head and between the top thereof and the collar on the spindle. This spring isconstructed and arranged to force the spindle down when free to act, so as to close the feed-opening in the base ofthe cup, as shown in Fig. 1. New, it

is evident that the spi ndlc must kbe raised and e held up when it is desired to feed oil from the cup, and in order to permit this movement the spindle is free to slide vertically, except i so far as theforce of the spring is exerted to hold it down.

To provide for the lifting of the spindle, a

. cap G` is mounted on the spindle, bein g provided with an angular aperture g, so that it will fit the angular section of the spindle, to the upper end of which it is applied. The

lower face of this cap is provided kupon its outer edge with two cain-lugs g', which stand oppositeto each other and are perpendicular on one face and inclined on the other, as shown in Fig. Ai of the drawings. In order to fix this head in its positionon tliespindle, a nut Il is turned upon the threaded upper end of the spindle and set down upon the upper face of the cap, and above this a jam-nut I is screwed down upon the first nut.

Now, it is evident from the above description that the spindle cannot turn, because of its angular bearing in the top of the neck on the cup-head, and the cap G cannot turn on the spindle, because it is fitted to the angular portion thereof. These parts are therefore held in a permanent relation to each other so far as rotary motion is concerned; but the thiinble mounted on the neck is free to be rotated about the neck and about the spindle, the opening in the top of the tliiinble being circular and sutiiciently large to permit rotation. Now, it is evident that when the thimble is turned underneath the cap, so that the lugs of the latter will rest i n the notches in the cani-ange of the thimble, the spindle will be let down under the influence of the spring. This is the position of the parts, as shown in Fig. l of the drawings, and the cap must be adjusted so that when in this position the spindle will be forced iirnily to its seat, and thereby completely cut off the feed; but when it is desired to feed oil from the cup the thimble is turned by means of its handle, so as to bring its inclined cain-faces into contactwith the inclined faces of the lugs onthe cap,

when it is obvious the latter will ride upon the former, thereby lifting the cap and of course with it the spindle, the spring yielding to accommodate kthis movement, and the thimble being turned around far enough to bring the lugs on the cap to rest on the long straight portion of thecani-llanges the cap the lugs of the latter are dropped into the notches of the canrllange and the spindle is dropped to shut olf the feed the tiiiinble may be brought into position, so that the aperture therein will register with the aperture in the head of the cup, as shown in Figs. l and 2 of the drawings, Wheinofccnrse,the cup may i be filled. The notches on the cant-flange are somewhat longer than the width of the caniihe former there is still possible sonic move `nient of the thiinble without disturbing the cap, so that the thiinble can be `turned into lags, so that whenk the latter aredropped into position to fill the cup and thon afterward shut off and close the filling-opening without in the least raising the cap. The nui'son the end of the spindle are for the purpose of adjusting the position of the cap on the spindle vertically, so that when the cap drops into the notches in the lifting-cani the spindle willfullyclosethe feed-a1ierture. `In putting the parts together the head of the cup should be slipped over the spindle before it is screwed down in place, the spring being also first put in position. The thimbleis then set over the neck 011 the head, the cap slipped on4 'the spindle above the latter, and the adjustingnuts turned into the required position. I thus obtain a simple, strong, and very durable cup which is easily operated. It will bc seen that the spindle-spring is practically Within the cup, or, rather, within a part of the head thereof. It will also be seen that the cup may be filled witliont lifting any of the devices from their position and that the piece or part moved for the purpose of filling is one and the saine with that employed to lift the spindle for the purpose of feeding.

There may be changes in some of the details of construction, and hence I do not wish to be understood as limiting myself in all parts to the special construction and arrange ment of all the devices herein shown and described.

IIaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In an oil-cup, the head B, provided with a neck rising therefrom, and a iilliiig-aper ture at one side, in combination with a thimblc D, mounted loosely on said neck and provided with aii aperture through its base and cams for lifting the spindle upon its head, and the cain-cap G on the spindle, arranged to permit the filling-aperture to be brought ICO IIO

into register when the spindle is down and out of register when it is lifted, substantially as and for the purposes specified.

2. In an oil-cup, the head B, provided with a central angular opening, in combination with the spindle E, provided With an angular section fitting said open-ing in the head, the spindle-depressing spring F, the thimble D, provided at its upper end With cams d and notches d2, mounted on the head, and free to turn around the spindle, the cap G, tted to the angular4 section of the spindle and provided with depending cam-lugs g, and the fastening-nut H, substantially as and for the purposes specified. 4

3. In an oil-cup, the head B, provided with a filling-aperture, and the neck b', having an angular opening b2 in its top, in combination with the spindle E, having an angular section e2 tting the opening b2, the spring F, the thimble D, mounted loosely on the said neck and provided with an aperture d in its base and a circular opening CZ through its top, the cam-flanges d on the top of the thiinble and notched, as described, the cap G, provided With the calnflugs g and an angular opening g, adapted to fit the angular portion of the spindle, and the fastening-nut H, whereby both the lifting of the spindle and the adjustment for filling the cup are effected by the turning of the thirnble in the proper direction about its axis, substantially as and for the purposes specified.
