LUBRIGATOR.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed February 26, 1906. Serial No. 302,839.

for its object to provide a simple, durable and efficient structural formation and combination of parts whereby a positive and multiple feed of the lubricant is attained without the use of inlet and outlet check valves, and with 5 which the amount of lubricant fed by each individual delivery can be independently adjusted or regulated as required, all as will hereinafter more fully appear.

In the accompanying drawings illustrative of the present invention :F igure 1 is alongitudinal vertical sectional elevation on line av-a 3. Fig. 2- is a detail horizontal section on line 55-50, Figs. 1 and 3. Fig. 3 is a transverse vertical section on line E fU Fig. 1. 4c is an end elevation of the operating cam. Fig. 5 is a detail plan of same, showing the arrangement of the 1nclmed pro ect1ons by wh1ch the sllding valve of the series of pumps is intermittently re- 20 ciprocated.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings :1 is the bottom plate or base of the apparatus provided with a longitudinal row of pump cylinders or chambers 2, the inclosing walls of which in the preferred construction of the present invention, as shown in Fig. 3, form an integral part of the base 1, with the inlet-outlet so ports 3, arranged transversely in said base.

a is a longitudinal channel formed in the base 1 and having opposed walls which con stitute the seat for the single controlling slide valve hereinafter described; through the inner of said walls the aforesaid inletoutlet ports 3 open, while tirough the outer of said walls a series of outlet ports or passages o, open, and are connected by suitable pipe connections 6, with the respective bear- 5'0 ings or parts to be lubricated.

7 is acasing or housing secured near the margin of the base i and adapted to inclose pump mechanisms, and contain a supply of the lubricant to be pumped, as usual in the present type of apparatus.

8 is an upwardly extending frame fixed on the base 1, for the support of the pump operating mechanism hereinafter set forth.

9 is the controlling slide valve above referred to having sliding contact with the aforesaid exposed walls of the longitudinal channel 4E, and receiving intermittent reciprocation by mechanism hereinafter described; such valve is formed with a series of ports or passages 10 extending transversely through the valve as shown in Fig. 2, and which in one position of the valve are adapted to register the inlet-outlet ports 3, of the pump chambers with the before described outlet passages 5 in the base 1; such valve is also formed with a series of angular passages 11 extending from the top of the valve to the inner side of the same, as shown in Fig. 3, and while in the other position of the valve these angular passages are adapted to register the inlet-outlet ports 3, of the pump chambers with the interior of the housing 7 and the supply of lubricant contained therein. In the present improvement the said passages 10 and 11 are arranged in alternate relation to each other as shown in Figs. 1 and 2, and the arrangement is such that in one position of said valve, the pump chambers will be in communication with the interior of the housing to take a supply of the lubricant, and in the other position of the valve communication between the pump chamber and the tank will be closed, and communication opened between the pump chambers and the series of outlet passages 5 having connection with the bearings to be lubricated.

12 are springs tending to hold the valve 9 to its seat in the channel 4- while permitting a free longitudinal reciprocation of the valve. Said springs are arranged between opposed studs on the valve and a stationary part of the pump mechanism, as illustrated in Fig. 1.

13 are the series of pump pistons or plungers moving in the row of pump chambers 2, aforesaid, with their upper ends connected to the series of open frontyokes 1a, which span the operating cam shaft hereinafter described.

15 are a vertical series of tubular guide stems at the tops of the yokes 14:, in vertical alinement with the pump 13,preferably, and moving in a longitudinal guide bar 16, on the frame 8, aforesaid.

17 are aseries of springs surrounding the guide stems 15, and arranged between the guide bar 16, and the tops of the yokes 14 with a normal tendency to forcibly depress said yokes and the pump plungers 13 car.- ried thereby.

18 area series of vertically adjustable of the adjustable screws 18, to have bearing,

contact on the lifting cams hereinafter described. With such'arrangement the direct wear'is upon saidbars so that when'much worn they can be readily and economically replaced. r

21 is a longitudinally extending cam shaft journaled in the frame 8, aforesaid; such cam shaft is commonto the series of yokes 14, and their individual accessories, and in the preferred form of the present invention such cam shaft is formed with a series of steps 22 in its cam portion, as shown in Figs. 1 and 4, so-that the down or active stroke of the series of pump plungers will take place serially, the one following the other in short succession, and the whole taking place in a small part of one rotation of the cam shaft.

23; is a disk or rim rotating in unison with the cam. shaft 21, and. preferably carried thereon; such disk is provided with a pair of inclines or cams 24', 25, arranged in diametric relation and projecting longitudinally from-opposite sides of such disks as illustrated in Figs. 1, 2 and 5.

2.6 is a vertical lever pivoted to a fixed part of the machine, with its lower arm in operative engagement with the slide valve 9, while its upper end is forked to straddle the disk 23 ,to be intermittently moved in one direction by the cam 0r incline 24c, and in the other direction-by the cam or incline 25, during a continued operation of the apparatus.

Any ordinary or usual operating mechanism may be employed to impart a slow rotation to the cam shaft 21, without departing from, the spirit of the present invention; the mechanism. shown inrthe drawings conslsts in an arrangement of parts as follows-:

27 is a. wormw-heel carried by the cam shaft and. preferably formed bythe-provision of a series ofworm teeth-in the periphery of the disk or rim 23; aforesaid. 28 is" a vertical shaft carrying an endless screw-or worm 29- pump chambers filled with the lubricant,

which mesheswithand drives the aforesaid worm wheel 27. 30 is a worm wheel on the upper end of thevertical shaft 28; and 31 is an endless worm or screw on a horizontal shaft32, meshing with-and driving the said worm wheel 30; the shaft 32 in turn receiving motion from a convenient power source.

The operation of the apparatus is as follows :VVith the series of pump plungers in their depressed position, as shown in the drawings, and with the valve 9 in a position.

to register the pump chambers with the interior of the housing 7, andwith a continued rotation of the cam shaft. 21, the series of yokes and their connections are gradually lifted by the cam formation into their fully raised position, previousto which the incline 25 moves against the lever 26 to shift the valve 9 longitudinally to close the communication between the pump chambers and the interior of the housing 7, and open communication between the pump chambers and the outlet passages 5. With the series of yokes, etc., fully raised and the the cam projections of the cam shaft, move 7 from under the yokes, and the same are forcibly depressed by the springs 17'to discharge the lubricant from the pump chambers through the outlet passages 5, and to the points, of use. A continued rotation'of the cam shaft'shifts the valve 9 back to its original position through the instrumens tality of the incline 24, to begin again a' fresh cycle of the operations just described.
