FLUSHING TANK.

Original application filed June 6, 1922, Serial No. 566,338. Patent No. 1,556,100, dated October 6, 1925.

Divided and this application filed December 1, 1924. Serial No. 753,285.

This invention relates to flushing tanks, and more particularly to water controlling means therefor.

The invention forming the subject matter ofthis application is an improvement over the construction illustrated in my several prior patents as well as a division of my application Serial No. 566,338, which was patented October 6, 1925, No. 1,556,100, and is especially designed for successful opera tion in places where the water pressure is low. However, the invention is also designed for operation in connection with high as well as low pressure systems.

Also the invention aims to provide a flushing device which is extremely quiet in its operation and which may be installed after the tank is set, without elaborate alterations.

A further object is to provide a flushing device having novel means whereby the same will operate when the pressure returns to a predetermined point, so that if the. pressure temporarily drops below a predetermlned point, the device will be operated as soon as the pressure returns.

A further object is to provide a flushing device which is of highly simplified'construction, durable in use, and cheap to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like partsthroughout the same.

Figure 1 is a side elevation of the improved flushing device, parts being shown 1n section,

Figure 2 is a fragmentary perspective illustrating a portion of the improved fiushing device.

Figure 3 is a. fragmentary perspective illustrating a slight modification of the invention,

Figure 4: is a similar view illustrating a further modification of the invention.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the inlet valve is designated by the numeral 80 and is provided with an attaching stem or branch 81 which is extended through the bottom of the tank. The branch 80 may be provided on I one side of the tank 82 with a flange 83 and on the other side with a nut 8 1 by means of which the valve may be securely held in position.

In carrying out the invention, the upper side of the valve casing 80 is provided with a long upstanding branch 86 to receive the valve 87 adapted to engage a seat 88 within the casing. I

Figure 1 illustrates that the upper portion of the valve 87 is arranged exteriorly of the branch 86 and is provided with a slotted head 89 which freely receives a lever 90 connected to a stationary bracket 91 as indicated at 92. The link 93 is also connected to a main actuating lever or float arm 94 pivoted as indicated at 95 to a bracket 96. The float arm 94 is in turn connected to a float 98 through the medium of an adjustable connecting member 97 which permits the float 98 to be adjusted with relation to the arm 94 whereby the supply of water may be cut ofi early or late. It is believed to be obvious that when the float arm 94 is forced downwardly, as will be later described, the lever 90 is forced upwardly so' as to permit waterto enter the tank. On the other hand, as the level of the water in the tank raises the float 98 will elevate thefloat arm 94 and thereby gradually close the valve 87 The discharge of water from the valve casing 80 is controlled by means of a secondary valve 100 slidable through upper and lower ports 101 and 102, the port 101 having communication with a priming jet 103 which directs the priming water into the siphon 104.

The lower port 102 supplies the water to fill the tank and when the valve 100 is in its lowermost position as illustrated in Figure 1, the transverse port 106 in the valve 100 is in communication with the port or passage 102 so as to allow the water to pass directly into the tank. On the other hand, when the valve 100 is in its elevated position as illustrated in dotted lines in Figure 1, the port 106 is in communication with the priming port 101 so that water will be passed through the priming jet 103. It will be observed that when the valve 100 is elevated the lower portion of'the same will completely close the port 102 so that all the water is directed through the jet. the priming of the siphon. During, the till ing of the tank a quantity of water is passed through the after till pipe 1129 for providing a water seal in the bowl.

The valve 100 which is weighted as indirated at 108 is pivotally connected to links 1119 which are in turn pivoted to a lever 110. The lever 110 is connected to a link 111 which includes upper and lower sections slidably connected in the manner illustrated in Figure 2.

The upper section of the link 111 is desig-. nated by the nuiineral 112 and is of lJ-shaped formation and has its bight portion formed with an opening to receive the lower portion oi the link. it. nut 113 is threaded onto the link 111 and regulates the ciiective length of the link.

The upper portion 01 the section 112 is pivotally connected to a main actuating lever 11 1 through the medium oil a pivot bolt 115 and with reference toFigure 1, it will he observed that the main actuating lever 111 is pivoted intermediate its ends as indicated at 118 to the bracket 91. A llenible element IQOlis connected to the main lever 11st, and when the llexible element is drawn u wardly the link 111 will be moved downwardly so as to. elevate the valve 101) and as previously stated, when the valve 100 is elevated to occupythe dotted line position in Figure 1, the prin'iingg oi the siphon is started.

Figures 1 and 2 illustrate'that. the pivot bolt 115 engages the float arni 9-1 as the float arnpis confined between the sides of the U shaped section 112.

In operation. the flexible element 120 is operated so as to swing the main actuating lever 11 1 in a counter clockwise direction. \Vhen the lever 1151 is thus operated, the link 111 is forced downwardly so as to swing the valve 100 upwardly and thereby permit the water to pass into the siphon by way of the jet 103. lever 1141, is swung about the axis 118 the pivot bolt 115 will engage the float arnill-l and fithcrebvswingr the same downwardly against the buoyancy of the ball 98. As the float arm {)1 is swung downwardly the pivot belt 115 will ridenlonn' the inclined upper edge 350 of the tloat arm and the pivot bolt will then engage a locking shoulder 121 formed on the heat arm. lVhen the pivot bolt 115 is locked in engagement with the shoulder 121. the Heat arm will be locked dmvnwnrdly and consequently the valve 87 will he held in an elevated position even while the water in the tank is at a hi eh level.

llou'ever. as the ater is discharged from the. tank and the level. drops, the float arm 91 will drop below the point at which it was locked and the link 111 will therefore he released. Vi hen the link 111 is thus released.

the weight 108 will return the valve 100 to This occurs only during However, when the main o iieratin its seated position so that the water which is supplied through the valve casing 80 will relill the tank.

in use, the parts normally occupy the position illustrated in full lines in Figure 1. and when the flexible element 120 is operated the valve cl? will he unsealed and. the valve 100 will be simultaneously elevated so that all the water will be directed into the siphon :tor priming the same and when the water drops to the level. at which 1 the float is locked. the link 111 will be released so as to permit the valve 100 to return to: its original position, and thereby cause the tank to reiill. As the level of the water in the tankiis again raised the final: 98 will of course be elevated for returning; the valve 87 to itsscated position.

in carrying out the invention the utter hll pipe ltli) is extended into the top otthe vent. pipe 110 and discharges the water for =the at'ter till into the pipe 170. in the form 01 the invention illustrated in Flour-e3 the outlet ports are designated by the numerals 150 and .151 and are provided with a rotate able valve 152 having ports 153 in C0l1']1l"ll1. nication with the ports 150 and. 151. The valve 152 is provided with a crank which is adapted for connectionwith a. link 1156.

by means of which it is operated. If de sired, a suitable vent pipe 158 is connected to the port 151 and the vent pipe will inithah case be joined with the siphon.

in the 'lorln ol" the invention illustrated in liiguro t there is provided a singleoutlet port 161) tl'iroughwhich a valve 1151 ex--- tends and the alvc 1111 is provided with a radial crank 162 which is connected to an operating link.
