GREASE-CUP.

Specification of Letters Patent.

, PatentediMar. 2.2, 1921.

Application filed June 25, 1920. Serial No. 391,626.

To all whom it may concern:

Be it known that I, DAVID EARL HARD- MAN, a citizen of the United States,and a resident of Simms, in the county of Gascade and State of. Montana, have invented certain new and useful Improvements in Grease-Cups, of which the followingis a specification.

My invention relates to grease cups, and a purpose of my invention is theprovision 0 a grease cup in which there are no screw threaded portions to be'removed when refilling the cup, thereby eliminating that nuisance common tothe usual grease cup' of remeshing. the threads of one part with those of another whenclosing the cup subsequent to the filling operation.

It is also a purpose of my invention to provide a grease cup having a cap which is quickly and easily removed, and means asso- V ciated with the cap for automatically locking the same against accidental displace ment.

I will describe one form of grease cup embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings:

Figure 1 is. a view showing in sideeleva tion one form of grease cup embodying my invention. i

Fig. 2 is a vertical sectional view taken onthe line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 33 of Fig. 1. i

Figs. 4 and 5 are detailed views showlng in perspective the container portion and cap, respectively shown in the preceding views. 7

Similar reference characters refer to similar parts in each of the several views. I

Referring specifically V to the drawings, the grease cup essentially consists of a base B having formed integral therewith a screw threaded stem S which is adapted to be fitted within the element to be lubricated so as to'support the cup as a unit thereupon. Rotatably mounted upon the base B is a container 0 which is adapted to receive and house the grease to be dispensed. The container C has removably fitted thereon a cap K which closes the upper end of the container, as will be understood. 7

As illustrated to advantage in Fig. 2, the base B and the stem S are bored axially thereof to provide a duct 15 through which lower edge of the grease from the container C is adapted to be ejected from the cup. The periphery of the base B is screw threaded, and similarly the inner wall of the container C is screw threaded to threadedly engage the base. The cap 'Kdoes not threadedly engage the container C but is provided with means engageable with means uponthe container for securing the cap totlie container and locking the same against accidental. displacement therefrom. This means, in the PATENT: orator..- 1

present instance, comprisesa pair of flanges designated at Fv disposed at diametrically opposite points upon the periphery 'of the container and arranged spirally. with respect to each other. As shown in Fig.4,

the widest end of each'of the flanges F is provided with a lug 16, and adjacent the 7 narrow end of each flange is ajnotch' 17. Arranged at diametrically opposite points upon the cap-K and in depending relation thereto are a. pair of arms A of substantially U -shaped contour in cross section.

These arms, as well as the flanges F, may be" formed integral with their respective members, the arms being adapted to engage V the flanges in the manner shown in Figs.

' 1' and 12 sojthat when rotated in the direction of the widest. end of. the flanges the arms firmly. engage the same and thus se cure the cap in closing position upon the upper end of the conta1ner,; it being understood that thelugs 16 limit the movement ofthe arms into locking position; To prevent accidental disengagement of the arms from the flanges, a leaf spring R is pro-.

vided, 'which in the present instance, is shown as being formed integral with one of the arms A and provided at its freeend with an inwardly bent hook18 which,in

the applied position'of the cap, is adapted to engage either of the notches 17 and to thereby lock the cap against rotation upon the container. p I

As shown in Figs. 1 and2, the lower edge of the base B is beveled as indicated at 19,, thepurpose of which is to provide a surface against which a pair of fingers G is adapted to abut for preventing displacement of'the container G from the base B. As shown'in' Figs. 3 andjfl, the fingers G areformed at diametrically opposite points upon the the container and are bent inwardly toward theaxis of the container-so as to engage the beveled. edge 19 when the container is in its uppermost position, thus preventing further rotation of the container to disengage the base.

To insure the removal of all grease from the container and base, upstanding lips L are formed within the base in the shown in Figs. 2 and 3, those lips serving to direct the grease to the upperend of the duct T when the container C is rotated. v

In operation, the cap K having been removed, and the container G screwed to its uppermost position, the latter is completely filled with grease. The cap K is now applied by positioning the same so that the arms AA will be disposed between the flanges F -1 so that by rotating the cap in a clockwise direction, the arms will be caused'to engage the flanges in the manner previously described, and when the arms have reached a'securing position with respect to the flanges, the hook end :18 of the spring It automatically drops into one of the notches 17, thus locking the cap against accidental displacement. The cap 11 ving been applied, the cup is now ready for dis pensing of the grease, such operation being effected by a rotation of the container. downwardly upon the base, thus forcing the grease into the upper end of the duct and subsequently out of itslower end, as will be understood. 1

From the foregoing operation, it will be manifest that whenfilling the cup, the container C can be completely filled with grease and withoutany waste thereof because the container, when in its up )ermost position, can be completely filled 'withoutlmaking any allowance for plunger. or other device found in theiusual grease cup for efiecting the ejection of. the grease from the cup It will be further manifest that when the container C is screwed to its lowermost position, the upper edge of the base will engage the under side oft-he cap K, and under the action of the lips L, a complete ejection of the grease from the container is effected.

Although I have herein shown and describedonly' one form" of grease cup embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

hat I claim is:

1. A grease cup comprising, a base, a container threadedly' engaging the base, means for limiting the movement of the container on the base in one direction, a cap removablj fitted on the container and adapted to limit the movement of the container in either direction, and means for locking the cap on the container comprising, spirally arranged flanges on the'container having lugs on one end thereof and notches adjacent the. other end, arms formed on the cap and engageable with the flanges, and a spring on one x i ot the arms adapted to engage OlGllQl ot said notches for loclnngthecap against rotation.

" 2. A grease cup comprising, a base, a stem "formediintegral with the base, said stem and base being bored to provide a discharge duct,'a pair of upstanding lips formed in the base, a container threadedly mounted on the base, fingers formed on the container,

said fingers depending from the lower edge of said container and being bent'inwardly to engage said base when the containeris in a predetermined position, spirally arranged fianges formed' on the periphery of the container adjacent its upper edge, a cap adapted to clo'sejtheupper end of said container, arms carried by said cap and en'gageable with said flanges for securing the cap to the container. and eoacting means formed on said container and capl'or locking the latter against accidental displacement from the container. v
