CLEANER FOR LUBRICATION FITTINGS Filed March 18, 1948 IN V EN TOR.

flfz ovize yst Patented Aug. 23, 1949 UNITED- STATES PATENT OFFICE 7 Claims.

My invention relates to fittings generally applied to motor cars for facilit in greasing the same. A popular type of fitting presents a ball type receptacle for the application of a grease gun spout. In order for the latter to secure proper communication with the receptacle, the fit of the spout must be with a good contact. However, since most grease fittings on automobiles are underneath or exposed to dust, water or mud, the fittings become so coated or packed with solid matter that it is diificult to fit the grease gun spout to them.

It is therefore one object of the present invention to provide a tool by means of which the coating on the grease fitting may be quickly scraped off, whereby to expose the fitting receptacle for the application of the grease gun spout.

A further object is to provide a tool of the above character which is designed to fit the receptacle of the grease fitting retentively, whereby to fix the position of the tool in relation to the receptacle.

Another object is to provide the tool with a pair of spring jaws which may be tensioned when the tool is applied to the receptacle and serve as scrapers when the tool is rotated.

With the above objects in View, and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the accompanying drawing, in which- Fig. 1 is an elevation of the tool;

Fig. 2 is an elevation of a jaw assembly apart from the tool; and

Fig. 3 is an elevation of the tool, partly in section, showing its application.

Referring specificall to the drawing, Fig. 3 illustrates the type of grease fitting herein considered, which is known as the Zerk. Thus, the shank of the fitting is indicated at l0 and has a nipple II which is threaded into the automobile part 12 served by the fitting. The outer portion of the fitting terminates with a ballshaped receptacle I3 formed with a conical base 14.

As it is necessary for the receptacle I 3 and base M to be clean in order that the grease gun spout ma properly fit the same, the present tool is designed to accomplish the engagement and cleaning of the receptacle and its base. Thus, the too] primarily consists of a metal tube 20 which is chamfered at 2| to an edge at the forward end of the tool. The latter receives a cross-pin 22 near its rear end, such pin serving as a key for the manual rotation of the tool.

The forepart of the tube 20 is split in a diametrical plane to permit the insertion of a steel plate 2.3 As indicated in Fig. 3 this plate has shoulders 24 seating against the tube at the source of the split and defining a terminal portion 25 which extends into the tube. The outer portion is perforated at 26 to be secured in the tube by a cross pin 21.

Forwardly of the shoulders 24, the plate 23 is divided with sections 24a which are identical and intended to serve as jaws. The sections are normally convergent toward their forward ends, as indicated by their spacing at 28; They are then cut out with opposed concaved edges 29, and finally cut away with biased edges 36.

The edges '29 and 3|] correspond in form to the profile of the receptacle i3 and base l4 of the fitting I 0. Consequently, when the tool is applied to the fitting, the approach of the jaws 24a is directly toward the receptacle [3 While the tube mounts the latter. When the jaws meet the receptacle I 3 they are caused to spread and become tensioned until they surmount the receptacle as indicated in Fig. 3. The rotation 01 the tool by means of the cross pin 22 will noW operate to scrape the deposit of hard or foreign material from the receptacle l3 and its base l4, rendering these parts clean. When the tool is pulled oil the receptacle, the latter is exposed in condition to receive the grease gun spout in the usual manner.

It will now be apparent that the novel tool comprises a simple and handy implement for application to a fitting of the type described in order to quickly clean the same of hardened deposits or dirt. While the shank of the tool is rigid for strength, its jaws 24a are divided to be capable of spreading tension when they engage the receptacle l3 in order to make a retentive fit with the same. When this fit has been accomplished, the

edges

29 and 30 of the jaws act as scrapers when the tool is rotated back and forth to remove the objectionable accumulations from the fitting. Finally, it is evident that the tool is only made u of two major parts, and is therefore economical to produce.

While I have described the invention along specific lines, various minor changes or refinements may be made therein without departing from its principle, and I reserve the right to employ all such changes and refinements as may come within the scope and spirit of the appended claims.

I claimi I 1. A cleaner for a grease fitting having a balltype receptacle comprising atool having a plate extended for application to the receptacle divided from its forward end, the inner edges of the plate divisions being formed with opposed concavities suitable to fit the sides of said receptacle and serve as scrapers for the same when trained around such sides.

2. The structure of claim 1, the divisions being spaced so closely-as to become separably tensioned as they mount and overcome the prominence of said sides in assuming said fit with the same.

3. The structure of claim 1, the divisions being spaced with a forward convergence so closely as to become separably tensioned as they mount and overcome the prominence of said sides in assuming said fit with the same. W

4-. The structure of claim 1, said tool also having a tube directed with one end for application around the receptacle, the tube being split from such end to seat the divisions of said plate in those of the tube.

5. The structure of claim 1, said tool also having a tube directed with one end for application around the receptacle, the tube being split from such end to seat the divisions of said plate in those of the tube, and a cross-pin through the undivided portion of the plate and seating in the divisions of the tube to join the latter and the plate against longitudinal relative motion.

6. A cleaner for a grease fitting having a ball= type receptacle and a conical base for the same comprising a tool having a plate extended for application to the receptacle and divided from its forward end, the inner edges of the plate divisions being formed with opposed concavities suitable to fit the sides of said receptacle and with flared portions in forward continuation of such concavities, the latter and said portions serving as scrapers for the sides of said receptacle and base when trained around such sides.

7. The structure of claim 1, a tube carrying said plate in its forward end, and a cross-pin intersecting the rear-end portion of said tube and serving as a handle to rotate the tube on its axis and accomplish the training of said sides as stated.
