To all 'whom t concern? Y n Be it lmownthat I, BERNARD H. SKELLY,

a. citizen of-'the United States, residing at the city of Bridgeport, inthe county Vof Fairiield and Statel 'of Connecticut, have *invented certain new Aandl useful Improvements inLubi-icators; and I do declare the following to be a full, clear, and exact dev scription of the invention, suchA as will enable others skilled in the artto which it ap ertains to make and use the same.

his invention relates to certain` new and useful improvements in' a lubricator for forcing oil Vto a vplurality of bearings andy is'particularly `applicable for supplying the lublcant to thevarious bearings of an automo e.

Primarily, the invention resides in an im proved lubricating apparatus for eii'ecting an expeditious and thorough-.lubrication of all the bearings and joints to which it-is connected to thereby avoid the usual nuisance and inconvenience of soiling the hands and clothing as well as the great waste of both time and lubricant whichA are incidental Y to the oldzmanual .method of lubricating' the takenvv on line 4;-4 ofy F bearings independently of one another.

Further, the invention is Vfound in the following features of construction, and the arrangements and combinations of parts hereinafter described in detail and claimed in a succinct manner, reference being had to the accompanying drawing wherein, Y

Figure 1 is a top plan view of the improved lubricatingA apparatus;

Fig. 2 is a vertical transverse section thereof on line 2-2 of'Fig. 1;

Y said side walls.Y VThis arrangement and construction yprovides a lubricant chamber 4 which extendsfrom side to side around the ends of the body by reason of the latter terminating short of the end walls of the casing.

Thisblock or body is bored through its top to form spaced series of vertical cylinders 5 from the bottoms of which bored extensions 6 and 7 are made to provide vertically spaced seats 8 and 9 for the inwardly opening ball valves 10 and yll. Through the opposite vsides of the web part 2 bores 12 are made for establishing communication betweenthe chamber 4 and the respective passage 7. These passages 12 open through v the sides of the-web part beneath the over'- hanging wings 3 Aso that the inlets are practically housed thereby. l

Extending laterally from the bottom of each` cylinder and into'the adjacent wing part 3 is an outlet passage 13 and communieating' with this passage is a vertical passage 14 opening through the top of the body,

said vertical passage comprising a series of counterbores for providing the vertically p spaced seats 15 and 16 for the ball valves 17 and 18. Threaded in the upper end of passage 14 is a delivery pipe 19 extending upwardly within the casing and 'having its upper end deflected through and secured to the side walls of the casing. Thus, means are provided on each side for securely lockingrthe, cylinder block in the casing.

he plungers 20 are preferably headed to aiiord greater bearing surface for the plunger-depressing cams 21 and 22, said plungers being retained against the cams Aby means of the coil springs 23 which encircle the .plungers and bear upwardly on the heads of the latter. The upper end of the cylinder is iiared to receive a packing gland 241 which is held in place by the ring 25 on which the lower end' of the spring 23 seats. Pillow blocks or bearings 26 are provided at opposite ends of the body and in these are journaled the shafts 27 which xedly ous, a

In practical use, the lubricating mechanism or apparatus is installed in any convenient position on the automobile and the .several delivery pipes connected through piping to theV several bearings of the machine. The lubricant having been poured into the chamber 4 at-either end, opening between the body and casing, the crank handle is turned to rotate the cams in which -connection it .will benoted that-one cam is advanced substantially 180 over thecompanion cam 'for effecting alternate depressions of the plungers of both series at relatively timed intervals. .As the lubricant is drawn in on the upstroke of theplunger, the ball valves 10 and 11 unseat while the valves 17 and 18 close, this action being reversed ion depression of the plungers. Consequently, one or two turns of the crank handle will be effective in supplying suliicient lubricant to each bearing to which a delivery pipe leads.

Thus, may be accomplished in a fraction of a minute Athat which 'would require onehalf houror more under the ordinary method. of manually oiling each bearing separately beside avoiding all the inconvenience of soiling the hands and clothing and the waste of oil.

The chamber 4 being annular or continuerfect circulation of the lubricant is obtained. All of' thetpassa es and cylinders in the body are capable of being bored, the outer end of passage 13 being suitably plugged in an obvious manner.
