OIL-CUP.

SPECFIGATION forming part of Letters `Patent No. 697,082, dated April 8, 1902.

Application tiled June 15, 1901.

To a/ZZ whom t may concern.'

Beit known that I, BENGT M. W. HANsoN, a citizen of the United States of America, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Oil- Cups, of which the followingis a specification.

This invention is an improved cup for supplying oil or other lubricant to the bearings or journals of machinery of various kinds, the object being to provide a simple, inexpensive, and compact oil-cup which may readily be opened by the nose of the oil-can or by the finger and thumb of the operator for the introduction of oil and which when opened will' receive oil from any side of the cup at which the oil may happen to be introduced, which closes automatically upon the withdrawal of the can, and which when closed completely excludes dust, grit, and the other foreign substances Which'are liable to accumulate on and around the lubricated portions of machinery.

Figure 1 is aside View of one form of my improved cup. Fig. 2 is a side View of the same cup in section taken from its longitudinal center, showing the cup in its closed position. Fig. 3 is a View similar to that of Fig. 2 with the cup in its open or oil-receiving position. Fig. 4 is a modified form of this cup.

The cup illustrated in Figs. l to 3, inclusive, will rst be described. The oil-receiv ing body portion 6 is at its lower end adapted Ato be screwed into a bearing by means of a wrench. This body is provided with an internally-supported head 7, forming a cover for the cup, which for convenience of manufacture and assembling is preferably made in a separate piece, as herein shown, and is attached to the body by a screw-threaded stem S. Vhen employed as a reservoir-cup, as herein shown, the stern may also const-itute the feeding-tube for the oil and be provided with a piece of wicking 9, which passes through the longitudinal center of the stem or feeding-tube and extends out into the body or reservoir portion of the cup through the opening 10. V'Vhen employed as an ordinary oil-cup, the hole 10 should be near the bottom of the cup, so as to allow the oil to flow out by gravity instead of iiowing by capillary sean No. 64,667. (no modem attraction, as with the use of the wick. The thimble 1l is tted to slide like a telescopetube upon the body of the cup, either upon the 4inner wall thereof or preferably, as is herein shown, upon the outside of the body. The extent of the sliding movement is shown by a comparison of Figs. 2 and 3, being sufijcient to permit the introduction of the nose of an oil-can when in the latter position. When ciosed, as shown in Fig. 2, the thimble effectually contines the oil contained in the body and also excludes dust and grit from the exterior. In order to make the cup self-closing, which is preferable in most cases, it is provided with a spring l2, which rests within the body ofthe cup and abuts against an annular shoulder 13 of the t-himble, which eX- tends inwardly over the wall ot' the body of the cup far enough to receive the spring. This shoulder may also abut against the top of that Wall and serve as a stop for the d0wnward oropen position of the thimble, as shown in Fig. 3. The exterior of the thimble is preferably knurled or checked, as shown in Figs. 1 and 4, so that it may readily be grasped by the finger and thumb of the operator to open the cup when the latter is in a position accessible to the finger and thumb. The aperture in the upper end of the thimble, Which encircles the stem 8, is made larger than that stem and is preferably flared or countersunk, as indicated at 14, so as to provide ample opening for receiving the required volume of oilV from the oil-can. The annular form of this opening enables the oil to be applied from any side, so that it is not necessary for the operator to apply the oil-can at any particular side of the cup or to turn the cup or the thimble t0 any particular position for receiving the oil.

Where the cup is so located that it is difficult to reach it with the finger and thumb 0r where for this or any other reason it is desirable to employ but one hand for the oiling operation, the cup shown in Fig. 4 may be employed. In that cup the joint between the cover 15 andthe thimble 16 is beveled or a-red, so that they may be forced apart by the nose 17 of an oil-can, which will then be in position for filling the cup, after which IOO upon Withdrawal of the can the'thimble will be closed by its spring. This figure also shows another modification of the cup in the respect that the screw and squared portion are omitted, the plain stem 18 being intended to be driven into a hole drilled in the bearing.

I claim as my invention- 1. An oil-cup comprising a body portion having an annularl outwardly-extending internally-supported cover,and a telescoping thimble mounted on the body below the cover to close against the cover.

2. A self-closing oil-cup, comprising a body portion having an annular outwardly-extending internally-supported cover, a telescoping thimble mounted on the bodybelow the cover, to close against the cover, and a spring for resiliently holding the thimble to its cup-closing` position.

3. In an oil-cup, the combination of an oilreceiving body, provided with an upwardlyextending stem having an annularly-extending head, forming a cover for the cup, and a telescoping thimble mountedupon the body to close against the cover.

4. A self-closing oil-cup, comprising an oilreceiving body portion, a cover comprising an annular head attached to the body by a reduced stem, a telescoping thimble mounted upon the body to close against the head, and a spring for vresiliently holding the thimble in its closed position.

5. An oil-cup comprising an oil-receiving body portion, provided with an internallysupported annularly-extending head forming a cover for the cup, and a telescoping thimble mounted upon the body below the cover, having an annular shoulder forming a stop for the opening movement of the thimble.

6. A self-closing oil-cup, comprising an oilreceiving body portion, having an internallysupported annularly-extending head forming a cover for the cup, a telescoping thimble mounted upon the body, provided with a shoulder extending annularly over the Wall of the body ofl the cup, to form a stop for the downward movement ot' the thimble, and to form a shoulder for a spring, and a spring for engaging with the said shoulder to resiliently hold the thimble in its cup-closing position.

7. The combination, in an oil-cup, of an internally-supported annular cover therefor, and a thimble resiliently closing against the cover, with a flaring joint to be wedged open by the nose of an oil-can.

8. The combination, in an oil-cup, of an annular cover, secured to the body of the cup by a reduced stem, a thimble closing against the cover and encircling the stein With an annular outwardly-daring opening, for receiving the oil.
