Referring more particularly to the drawings, 10 designates a tank having a sloping bottom 1l leading to the outlet pipe l2, which descends to the bowl, and 13 designates the cover of the tank which is removable to give access to theinterior. A screened breathing opening 14 is shown in the upper portion of the tank above the water level. Within the tank is a tumbling or oscillating drum constructed with one side 15 of smaller radius than the opposed side 16, the difference in radius being indicated at the joining point 17 between these two parts. The drum is adapted to oscillate about the pivot point 18 and is provided with an open end 19 for receiving water when in the uprightposition shovvn in Figure 2 and for discharging the water when in the inverted position shown in Figure 4. l

rFhe tank receives water from the spout 20 from a supply pipe 2l that is connected with the city service mains or other source of water supply. The pipe 21 connects Witha valve casing 22 shown more particularly in Figures 7', 8 and 9 and within the valve casing is a valve seat 23 cooperating with a reciprocating valve 24 having the stem 25 which is guided for movement in the socket 26 of the casing.` `A slot 27 in the stem 25 provides for receiving the upstanding finger 2S on the rock shaft 29 which is disposed transversely through the valve casing and on the exterior thereof carries a dependingA pin 30.` This pin is more particularly shown in Figures 6 and 7.

A sleeve 31 surrounds the pin 30 and is .slidable thereon, the sleeve being provided with a lower conical or tapered end 32 for cooperating with a trip linger 33 carried by the drum. This trip linger 33 is pivoted at 34 to the bracket arms 35 and 36. .The upper ends of these bracket arms are provided with a bridge piece 37 against Which the finger 33 is adapted to rest in one position. The bracket arms 35 and 36 are provided with the :feet 38 and. te which are riveted er etherwise secured to a plate which spans the opening 19 in the drum and is secured to the side walls ot the druln in any appropriate manner.

The valve casing 22 is secured upon a bracket arm 41 and this bracket arm is in turn carried by a bridge piece 42 which ex tends across the tank above the drum and is secured to the side walls of the tank as indicated. The sliding sleeve 31 is affixed to a block 43 having a socket 44 to receive the cres cent-shaped cam 45 and a cut away end wall 46 to receive therethrough the shat't 47 to which the cam 45 is aixed. As indicated in Figure 7 the cam 45 carries a pin 48 for contact with the wall of the socket 44 to eliminate friction and to rest in the posit-ion shown in Figure 7 against the wall of the socket 44 whereby to resist movementof the cam.

The shaft 47 extends upon the exterior' ot the tank where it is provided with the hand lever 49 for rotating the shaft and the cam. A weight 50 on the shaft 47 wit-hin the casing is adapted to hold the parts in the normal position Yand to restore these parts to such position after each actuation.

'Within the drum is a vacuum breaking pipe 51 which has one leg extending into the drum and opening near the center of the tank, While the other leg 52 extends upon the exterior of lthe drum and lies along the eXterior wall, whereby its open end may lie above the water level as shown in Figure 4. The open end of the leg 52 may be protected with a baille or otherwise as desired.

A float 53 is shown in the upper portion of the drum, such float being on a lever 54 fulcrumed at 55 to` a bracket 56 carried by the drum. Fulcrumed at 57 on the other end of the lever 54 is a pin 58 projecting up through an opening 59 in the drum wall and adapted to cooperate with a projection 60 on a locking dog 61 pivoted at 62 to a fixed arm 63. The arm 63 may be aliixed to the bridge piece 42 or to any7 other appropriate part. An abutment 64 is carried on the arm 63 to restrict the movement of the dog or d etent 61.

A ballast cup 65 is carried within the drum to one side of the drum center 18 and preferably near the bottom of the drum. This cup `is cut away and open at its upper portion 66 and its pivot 67 is off center and displaced upwardly, whereby the cup 65 which is al vays full of water will, by virtue of the weight of the water it contains, always remain in the upright position. In this connection compare Figures v2 and 4.

A second ballasting cup 68 is mounted in the drum to the opposite side of the pivotal center 1,8. This cup is ofv larger capacity than the cup 65 and it is mounted 1n the smaller half oft-he drum. The upper portion 69 of this cup 68 is cutaway and open to rereive wat-er from the tank and the pivot l 70 is also displaced upwardly so as to at all times maintain the cup 68 in the upright position.

Compare Figure 2 and 4. One or more portorations 71 are formed in the lower portion of the cup 68 to permit of the slow discharge of the water, as indicated in Figure 4.

In the use of the device, the parts may be said to'be initially in the position shown in Figure 2, where the d rum is uprightand water is entering through the spout 20, the valve in. the casing being in the open position. It will be noted that this valve is positioned so that it will open automatically by the pressure of the water thereafwiinst. This open position of the valve causes the pin il() and the sleeve 31 to swing to the. position shown in Figure 2 and the block 4?) has a corresponding movement on the surface of the crescent-shaped cam 45. In this position the piu 58 of the float device engages the pin 60 on the dog 61 and the parts are by this means held in the position, shown in Fig-ure 2, until such time as the water level having risen to a predetermined height, the float 53 acts to y'ithdraw the pin 58 downwardly below the companion pin 60: whereupon the drum is released. Due to the greater volume of water held in the right hand larger portion 16 of the drum, the drum is over-balanced and will tend to rotate about its center 18 in a clockwise direction viewed in Figures 2 and 4. However, it will only be permitted to move a very short angular distance before the trip linger 33 engages the lower end of the sleeve 31.

This arrangement is shown in Figure 7 in which the linger has moved the sleeve 31 and consequently the finger 30 over a sufi'- cient distance to close the valve 24 and prevent the further admission ot the water. The trip finger will be held by the bridge piece 37 and by the angular toot piece 72 from backing oil' the sleeve 31. The parts will now remain in this position, with the drum 'full of water and in readiness Jfor the flushing operation. until the handle 49 is mtated. By rotating the handle, the shaft 47 is rotated together with the cam 45 and the high point of the cam will raise the block 43 and with it the sleeve 31, withdrawing this sleeve from the path of the finger 33. The drum is thus releaf-icd so that the over-balancing weight of.' water may topple the drum from the poliition shown in Figure 2 to that shown in Figure 4. The water will be discl'larged. through the inverted opening 19 into the tank 10. The oi'ienirrgr 19. it will be observed, is of greater diameter than .the pipe 12 whereby the discharge of wat-er from the drum and into the tank will take place at a greater rate of speed than the departure of the water from the tank 10 and into the pipe 12.

The ballaseing device will revolve with the drum and they will also rotate about their Cil oivii axes to the position shown in Figure Ll. Ihe device 68 being ot greater capacity than the device 65 and being situated at a greater distance from the center 18 when the parts are in the inverted position, such ballasting device 68 will assure that the drinn remains in the inverted position, until all, or subl stantially all of the water is discharged into the upright position. Now it will be understood that as soon as the drinn is released from the upright position that the Water valve 24:

will again be opened by the pressure of Water, and as indicated 1n Figure 4 the Water Will continue to lioiv on the closed bottom of the Adrum and about the drum into the tank thus providing additional Water for the relill operation. This continued flow of Water from `the spout is also advantageous that such Water catches beneath the vane 73 carried by the bottom o'f the tank and being so shaped and disposed as to react with the discharging Water whereby to propel the drinn back to initial position.

Stops 7 4 and 75 are provided to restrict the toppliiig movement ot the drinn, the stop being carried by the drinn bottom and the stop 7 4 by the tank. When in the position shown in Figure 4, the interior of the inverted drinn above the Water column is placed in coinmiinication with the upper air space of the tank 10 by means ot the pipes 51 and and the 11iterior of such drinn may breathe freely through the breather opening 14e ot the tank thus preventing` the formation ot the vacuum I which Would prevent the ready discharge of the Water from the drinn and result in the ineiiicient action in the iiushing operation.

Uien the drum returns to initial position, the pin 58 vvill strike the pin GO and liit the detent 61 up to the dotted line position permitting 'the pin 58 to pass the pin 60; whereupon ,trip finger 33 Will serve to restore it to npl right position in readiness to engage the sleeve l 31 on the return movement of the dinni in a clockwise direction. I

Due to the arrangement, the drum in falling y to the inverted position Will do so quickly but it yWill be checked bythe action of the Water and by momentary vacuum formed in the drinn whereby the stops 74; and 75 'iviil come o'gethelr only gently and Without noise.

drum to the upright position.

As shown in Figures 6, 10 and 11, the block 43 carries a strip 77 Which loosely hangs from the block 43, the strip being hingedly secured to the block as by a screw 76. A seat or ledge 78 for the strip 77 is fastened to the part 3S vertically beneath the pivot point 76. The object of the strip is to keep the block in an elevated position when the handle t9 is turned either to the right or lett and the drinn at that instant has not been filled to predetermined capacity.

The block being in an elevated position will keep the part 32 out ot' the Way of the part 33 and When the drinn has iilled Will topple over and discharge automatically. On returning to filling position the drum Will leave the strip 77 in the position shown in Figures 10 and 11. The advantage of this device is that if the drum is not full when one tries to make it dis- Y charge it Will not discharge but Will leave the parts Vin such condition that subsequently when the predetermined capacity of the drum is reached it will discharge automatically.
