Zio @ZZ wfwm et may concern:

Be it known that LBERNARD H. SKELLY, n citizen of the United States, residing et tliecity or Bridgeport, in the county ot Fairfield .and State of Connecticut, have invented certain new and useful improvements in 'Force-Feed Lubricators; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

.lily invention relates to force feed lubricators substantially like the lubricator shown and described in my Patent No'. ,2i38,869, issued June 1 8,- 1918 or in my 'pending application, Serial No. 262,432, 'led November il, 1918, and has for its object to pro'ide for selective lubrication or limited lubrication in instances Where' the lnbricator pistons or plungers are actuated by a. cam or by a plurality of earns that are rigid together and have tbe same axis oa'' rotation. I

ln my `prior Constructions, selective lubrication uns obtained only by employing separate series of plnngers and actuating cams, and tbe cam or cams of each series had. of course, diiferent axes of rotation. n my present invention, either a single plunger r any number of plungers, in a series of plunggers that are actuated by a single cam or b v a plurality of cams havingl the same artis oi' rotation, may be so disposed that either a limited lubrication Will be had or no lubrication whatever.

' ln the aocornpanyinteY drawing- Figure l is a sectional elrvation of a stru-:ture embodying my improvement, the section. being1 taken at the line 1-1 of itin'.

Fig, 2 a section at tbc line 22 of Figi. 2S a broken sectional elevation, similar to Fiji. l. but showing; a plunger completely depressed and locked down. and

Fin'. -ta view similar to Fig. -l but showing a plunger locked down when partly depressed so [lult suoli plunger will bave a short pumping' roke 'fol limited lubrication.

'limilar numeral,`4 or" reference deuole like paris: iu lic Several figures' of iluI drawing.

A casing or rwervoir l llas` a over plate by tile removal of u'bii'li arress mayy be obtained to the interior Working mechanism of the lnbricntor.

Il cylinder block 3 is contained Within the casing and may be formed therewith or separately secured therein as desired, it merely being necessary that there should be suitable communication between tlie oil in the reservoir and the inlet flof each pump cylinder.'

The bottom ot each cylinder is counter bored to provide valve seats for the valves S.'

Laterally and outwardly from each cylinder leads an outlet port 7 adapted to receive a valved nipple (not shown) for connection With the mechanism to be lubricated.

A plunger 8 is vertically operable in each cylinder, and the planners are nor,- nrally held in elevated position by encircling coil springs 9 interposed between the .heads l0 ot' the plungers and the cylinder block.

Above the plnngers is a cam shaft l2 Whose ends are suitably journaled in the end walls of the reservoir, the sliai't being extended and provided with a suitable crank 13 for purposes oir' operation, but of Course. a Wrench bold on tbe shaft for attachment of a ratchet Wrench Can be einployed instead of the cranl-.

Ypair of cams il and l5 are carried on the sl1al"t ,said cams being longitudinally and eceentrically bored to receive tbe shaft, and are fixed thereon by the transverse key pins 16. The cams are relativelv at an angle of approximately 180", i

As. slio'xvn in the drawing there are tu'o sets of plunger-s S' which are always held against their respective cams by the springs 9.

The construction far as described is the saine as that forth in my pending application above noted, the object being to provide for a clear understanding or mv present invention without any particular or detail rcfercnclo said application.

Non', )vitli solo regard to the present iinproveinent, attention will be called to the manner in which limited or selective lubrication is eli'oeted.

17 is a ledee extenfliino` from the block 3 and m'cilizlxig'iiioa the reservoir, and le? are vertical rods` Whose lower extremities .are fixed in any suitable manner to said ledge and whose upper ends are screw threaded.
