granted'Nov.. l0, 19111-, ,there is. disclosed another-'automatic cellar drainer of the iioat actuated ejectoraype., and in thisinnd` the prior patentitheejectorvalves are vertically disposed with reoiprocable valve stems or rods extending` vthrough stuiiingboxes. Such cellar drainershave been extensively used f andhave proven satisfactory, butit has been found that `other improvements-.to he. hereinafter referredto',materially contribute to the e'l'liciencf,T of' the cellar drainer, besides, reducing. the expense yolf: manufacture4 andV maintenance oiV the cellar drainer.

Considering oneol theimprovements it has been found thatany stu'l'ling box coml taining a reeiprocable nieinberrequires more attention than a stui'iing boxl ycontainiifigy a rocking or rotary member, therefore, the present invention includes an ejector; which is actuated through the medium or" a .rocking ork oscillatory member arrangedk in a laterally disposed stuiiing box. ,f

Screwed on the connection i is dome or chamber 10, and connected to said donne and communicating. therewith is a suction or stand pipe 1l which is adapted yto, extend abovek the llevel of waste waterthat may accumulate within the pit or well :Suitably connected to the upper; end of the suctionpipe 1l is a depending nipple l2 of an ejector casing 13, this casing having` its longitudinal axis at a right angle to the axis One endoffthe ejector casing 13 i's reduced andy suitably reinforced to afford a restricted portion lel and 16 is adapted tc extend out of the pit or well 3, and is placed as close to the of the suction pipe 11 as possible.

The ejector casing 13, adjacent he nipple 12, has a partition 13 supporting a detachable ejector nozzle 19, said nozzle being of a conventional forni tapering inwardly from its inner end to its outer end with its inner end serving as avalve seat and its outer end extending across the axis of the nipple 12 into the restricted portion 1t of the ejector casing.

Adjacent the partition 13 'is a connection 20v for a high pressure service pipe 21 adapted to extend ont of the pit or well 3 and receive water or other fluid under pressure.

Contiguous to the connection 2() is another partition 22 for a detachable combined guide and bearing` 23 disposed in the lon-k gitudinal axis of the ejector casing 13.' The outer end of the bearing 23 affords a cup shaped guide 24; for a valve 25, said valve having a stein or rod 2G slidable inthe bearing The valve 25 confronts the inner end of the ejector nozzle 19 and detachably inounted in said valveis a wear ineinber 27 which seats on the inner end of the ejector nozzle 19. rlhis wear member may be niade of liber or any suitable material possessing tight seatingqualities, and it might be mentioned that all parts fof `the draining device are of such materials not i subject to corrosion or slime7 and consequent inoperativeness.

The inner end of the valve rod 26 is reduced and provided with a detachable flanged collar or spool 23 lengaged by the opposed pins 29 of a yoke 3() mounted on a ktransverse rock shaft 31, journaled in a transverse housing 32 forming part of the ejector casing. One end of the transverse housing 32 affords a bearing 33Yfor the in `ner end of the rock shaft 31, and the epjmsite end of the housing 32 has a conventional forni ot' stn'l'ling box 3-1- through which the rock shaft extends. (ln the rock shaft 35 against which the ,racking of the stutlin-'r h M H ,bon is placed and retained by the gland of the stuHing box. The rock-shaft 31 also has a squared or facet portion for the yoke 30, so that said yyoke may be actuated by the rockr shaft 31 to reciprocate the slidable valve rod 26.

The yoke 30 may be placed within the transverse housing' 32 through the end of the ejector casing 13, and this ,end of the ejector casing isnorinally closed by an end plug or cap 36. v

Suitably mounted on vthe outer end of the rock shaft 31 is a lever or crank 37 having` its outer end provided with transverse pins 3S and loose on the outer end of said lever, between the pins 3S is a longitudinally slotted upper end of a link or arni "0 carfthe l' ried by the vtop of a float il-0 slidable longitudinally of the suction or stand pipe 11. The float 40 is of a conventional forni having a central passage providing clearance for the suction pipe 11 so that said suction pipe will serve functionally as a guide for said float. v

1n operation,` the water or fluid under pressure in the ejector casing 13, between the partitions 1S and 22, does not interfere with the opening of the valve 25, since said valve is reciprocable in thev guide 24, and any adjustment of the valve relative to the ejector nozzle 19, is practically noiseless. .Vith the ejector mechanism and the greater part of the draining device above the level of the wastewater within thev pit or well 3, `the waste water cannot interfere with the operation of the draining` device nor cause the deterioration thereof. As waste water accumulates in the pit or well the float el() will be'raised, and due to the elongated slot in the upper end of the link orarin 39, the float 40 will have a predetermined movement before actuating the rlever 37. Assuming that a sufficient quantity of waste water has accumulated 'within the pitor well 3 to raise the float .l0 and actu'ate the lever, 37, said lever rocks the shaft 31 and swings the yoke 30 to retract-` the valverod 26, thereby opening the valve and establishing cornn'iunication between the high pressure service pipe 21 and the ejector nozzle 19. rlChe high pressure. of water passino` froin the ejector nozzle 19 through stricted portion 1.4L of the ejector casing 13 produces a partial vacuum or reduction of Aiatniospheie pressurewithin the ejector casing 13 and the suction or stand pipe 11, resulting in the valve 5 beingraised dand the rwaste water drawn upwardly from the cage 1 through the suction or stand pipe 11 into the ejector casing 13 and out through the waste pipe 1G connected to said ejector casing. The ejection of the waste water continues until the level `of waste water within the pit orwell 3 .is niateri ally lowered and when the float el() assumes normal position the link or arin39 thereof actuates the lever 37 which in turnrocks the shaft 31 and causes the yoke 30 to shift thevalve rod 26 and seat the valve 25 relative to the ejector nozzle 19 thereby closing the ejector nozzle and by shutting off the lnotive fluid thereto the draining device becomes inactive for draining purposes and so reniains until suiiicient' waste Water has accumulated within the pit or well 3 to again actively operate the float L10 and the ejector mechanisrn.

From the foregoing, it willl be observed that the rod 26 is horizontally disposed and completely inclosed by the ejector casing, consequently it is unnecessary to use any packing in connection with the combined lll) -during the operation of the rock shaft.

guide and bearing 23. l/Vith the valve rod horizontally disposed and the valve partly housed by the guide 24 less torce is required to shift the valve rod, as the friction or resistance is reduced to a minimum. rlChe saine is true in connection with the rocl; shaft 31, which is horizontally disposed in the stu'tling boX EA, and this arrangement possesses distinct advantages over a vertically disposed stuffing box having a reciprorable valve rod therein, as shown in the prior Pribil patents previously referred to. With the valve rod reciprooable in the stuiting box, there is a long :trictional resistance against the movement ot the rod by the packing in the stutling box and it the packing is too dense or tight more force is required to shiit the valve rod, and it the packing is loose to reduce the trictional resistance there is leakage between the packing and the valve rod. lt is therefore evident that the stuiiing bonr of the reciprocable valve rod requires repeated packing and greater attention than that of a rock shaft in a stuiiing box, tor the reason that a roch shaft has a smaller degree of movement in the packing and the packing is maintained more uniform my constructive arrangementt partsthe stutling box Bil cooperates with the combined guide and bearing in preventing leakage. lt is practically impossible Jr'or the motive iiuid or liquid, as steam or Water, to enter the guide 24 and pass between the valve'rod-26 and the bearing 23, lout should any motive Huid enter the transverse housing 32, then there is the stutting boi; 34; to prevent leakage. Comparing my improvement With the construction disclosed byi the prior lPribil patents, it will be noted that my structure is more compact the operating mechanism enclosed to a greater degree, besides ythe structure is more durable and rigid throughout.
