;To all whom it may concern: Y

Be it known that I, Anromn Sonny, of Lyon, France, a citizen of the French Republic, have invented certain new and'useful Improvements in Lubricatingrcups, of whichthe following is a specification.

e of the cap is serrated and the said cap can be rocked in any direction in order to expose one or other of the openings formed by the serrations in its edge and through which is introduced the nozzle of the oil can for fill-f ing the lubricator. The cap is restored to its medial position by means of a laterally flexible spring which is so arranged that one of its ends is axially secured internally to the lubricator and the other end is similarly cap in such manner that the spring constantly tends to restore the cap to its normal position and tends to keep it in said position in order to insure "a dust-tight closure.

The annexed drawing shows an example of construction of the invention.

Figure 1 is a vertical section of the oil cup, the cap of which is closed.

Fig. 2 is a plan view of- Fig. 1.

Fig. 3 is a similar section, the cap being open and Fig. 4 is an elevation of the lubricator arranged horizontally, the cap being open.

The lubricator is composed of a body a having .a cylindrical outer surface comprising a hexagonal surface either at b or at c, as

shown in Fig. 4, this hexagonal surface serving for putting in place or removing the lubricator. The inside of the body a is conic at its base and spherical at its top at d. i

The cap or lid 6 is a portion of a'hollow sphere larger than a hemisphere on theedge of which are provided semi-circular and equidistant notches h. It is provided with a button 9 projecting externally and prolonged inside the sphere by a pin of which the length is so determined that it does not reach the central point of the sphere.

7 A spiral ameter is slightly-greater than that of the I N T MTM- S PATENT; me 1 spring 7, of which the outer dicylindrical central passage forming an ex-- tension of the. inner conical surfaceof the body a, is forcibly helved. by one of its ends 'into the said passage in order to be secured in. the body aiand lie in the central part of latter while still leaving. for the: oil introducedxinto the lubricator. The other end of said spring engages on the pin of the button g V and 1s thus attached to the cap e,"as shown in Figs. 1 and 2.

The length of said spring is so calculated that it is slightly compressed when the cap 6 is placed in the body a so that the edge of the cap presses against the spherical part d.

In ,mounting the parts, the edge 8 of the part b of the body a is afterward turned in against the outer surface of the sphere, while still leaving the necessary play for allowing the rotation of said sphere in its socket, from which it can no longer beremoved after the aforesaid edge has been turned inward.

The slight compression of the spring f is suflicient to constantly push the cap against the edge of the socket (Z without preventing the free rotation of said cap by the operators fingers which grasp the button 9 on the. surface of the cap. I

This cap can be rotated horizontally on its own axis as the spring is not secured to the pin of the button 9 and it can also be tilted in all directions while bending the spring 7 as shown in Fig. 3. Owing to said simultaneous or successive rotation and tiltof the lid there is obtained without trouble a lubricating hole whatever the position of the body a, as one or other of the notches h is brought forward and through whichthe oil can be introduced into the lubricator by passing through said orifice.

The oil cup can be arranged horizontally as'represented in Fig. 41 or in any inclined position between the horizontal and the vertical.

leased it immediately returns to its normal position (Fig. 1) under the action of the spring f. The closure is thereforeautomatic and dust-tight, and there is no fear of leakage of oil when the lubricator is'in an inclined or horizontal position.

The lubricator cup can be constructed in When the cap hasbeen tilted and then re- I i What I claim as my invention and desire to secure by Letters Patent of the United States is Y 1. A cup comprising a body having a bore and a chamber having an internally spherical mouth in continuation of. said bore, a hollow cap in the form of a portion of a sphere larger than a hemisphere fitting in said mouth and a lateral spring one end of whichis axially fixed in said body and the other end axially fixed in said cap and allowing said cap to be tilted to allow oil to' be introduced into said chamber, the said spring automatically retarding said cap when released to the closed position.-

thereby.

A lubricating comprising a body having a bore and a chamber having an internally spherical mouth in continuation of said bore, a'hollow cap in the form of a portion of a sphere larger than a hemisphere fitting in said mouth, a knob on the exterior of said cap, a pin forming, an extension of said knob extending-into said cap, and a laterally flexible helical spring, the one end of which surrounds said pin and is axially held thereby, and the other end fits tightly into said bore and is axially held In witness whereof I have signed this specification in the presence of two wit- DGSSGS. p
