FLUSHING APPARATUS.

Specification of Letters Patent.

Patented Sept. 8, 1914.

Application filed March 6, 1913. Serial No. 752,323.

To all whom it may concern Be it known that 1, JOHN Dnnron, a citizen of the United States, residing at Paterson, in the county of Passaie and State of New Jersey, have invented certain new and useful Improvements in Flushing Appara tus, of which the following is specification.

This invention relates to flushing appara tus of that type in which means is employed for mechanically lifting the body of water in the short leg of a siphon up over the bend and into the long leg of the siphon for the purpose of starting the siphoning action.

It is desired that the operating handle or lover in such apparatus shall have little throw or range of movement but that the means for transmitting the motion there-' from to the siphon starting means shall be such that the latter may have a throw suflicient always to insure starting of the siphon.

One object of the invention is therefore to provide a transmitting lever system which will impart the desired throw and yet be compact, i. 6., not only with respect to its over-all length, whereby to be adapted to the smallest tanks, and its over-all thickness, whereby to afford clearance for reaching down into the tank for access to the apparatus in assembling or efiecting repairs, but with respect to its over-all dimension when extendedv Another object is to improve the waterlifting means with a view to obtain a complete or exhaustive discharge of the water from the short leg of the siphon, while permitting the prompt reestablishment of the water in the short leg of the siphon upon the parts assuming their rest positions.

Another object is so to construct the siphon as to make unnecessary the packing of the opening therein through which the lifting means projects so as to cut off the inrush of air during the siphoning action.

In the accompanying drawing, Figure 1 is a side elevation. partly broken away, of the improved flushing apparatus; Fig. 2 is a fragmentary view illustrating the transmission means whereby the operating handle or the like is connected with the lifting means and also showing in section. that part of the siphon through which the lifting means projects; Fig. 3 is a vertical sectional view on the line a2m of Fig. 2; Fig. 4 is a vertical sectional view on the line @/j/ of Fig. 5 (and partly broken away) of the lifting means and the short leg of the siphon; and,

Fig. 5 is a horizontal sectional View through the short leg of the siphon in a plane above the lifting means.

As in my Patents Nos. 7 68215 and 833681 the siphon includes with the long leg a, penetrating and suitably secured in the bottom wall of the tank 6, a short leg 0 which is appreciably greater in diameter than the leg at and in the present instance consists of a cylinder which is screwed into the neck or bend-member (Z of the siphon, in turn screwed upon the upper end of the leg a.

The part of the member (Z into which the cylinder 0 is screwed is a relatively offset portion (1 of member d forming a top wall or cap for the cylinder 0 of such form that the longitudinal axis of the cylinder passes through the cap exteriorly of the body part of the member cl.

Axially of the cylinder there is screwed into the threaded hole 6 formed in the cap (Z a downwardly dependin tube f. lhrough this tube extends the stem 9 of the lifting means also including a. piston h attached to the lower end of the stem and to be described in detail. 2' is a handle (in this case a short lever fulcrumed in a bracket 7' attached to the tank) for imparting the upward or starting stroke to the water-lifting means. For transmitting the motion from the handle 21 to the lifting means in a manner calculated to produce a material amplification of the movement effected I employ the following mechanism A triangular bracket 70 is secured flat against the inside of one of the walls of the tank and has an overhang Z resting upon and suitably secured to said wall. On a stud m in the bracket is fulcrumed between its ends a lever a. The long arm a of this lever, which is connected with the handle i by the link 0, stands normally approximately horizontal and is joined with the short arm n of the lever by the vertical portion 02. the arm 12 also extends substantially horizontally, and it is formed at its extremity with the teeth a The lever n is arranged in a vertical plane close to the inner face of the bracket 7c and hence to one vertical wall of the tank (Fig. 3).

p is a lever arranged side by side with and close to lever 72 and fulcrumed on a stud in bracket l2 horizontally alined with the stud m. On the side of lever 79 adjoining lever 01 it has a boss formed with the peripheral teeth 1, the same meshing with the teeth n of lever 12.. (I cast the lever 79 with an opening s opposite the toothed portion. of the boss so as to admit a file or other tool for finishing off the teeth of the boss.) The free end of the lever has a longitudinal slot 7, receiving the bent-off upper end 9 of the stem g, which has a nut g to retain said end in the slot.

In view of the foregoing it will be ap parent that although the handle i is allowed but comparatively little movement, still the motion transmitted thereby through the lever system is su'lliciently amplified so that a quick and considerable movement of the lifting means will occur. In the rest position of the lever it stainls downwardly inclined from its fulcrum, and as the angular lever n has its part at" elevated and its part wk iile 'iressed, part a can rise without projecting above the top of the tank, and part a can descend without interfering with the bent-oil end 5/ of stem 5 to an extent perfectly ample for insuring the needed extent of movement to the lifting means it.

The piston h is constructed as follows: a is a disk which is fixed on the lower reduced end of the stem r by the nut e and has on both sid is of the diametrical rib w the relatively large openings :0. In the pairs of upstanding lugs 3 formed on the disk close to the rib w are arranged pintles .2 fm'i'ning fulera for the pivoted valves 2 each having pairs of upstanding lugs 15 penetrated by the pintles and so arranged that when the valve is in the closed position its inner edge 2' underlies and may bear flat against the rib u.- while its outer edge overlies and may lie flat against the edge of the disk to at the outer side of the corresponding opening In the working stroke of the piston, there fore, the latter willv be substantially closed at all points. In the return stroke, inas n'nich as the part of each valve at the outer side of its fulcrum. is of materially greater area than the part at the inner side thereof. the valve will be turned on its fulcrinn until it is stopped by the stem 9. In this position it will remain, however, only so long as the pressure of the water passing through the siphon is su'l'lieient to maintain it there, upon which gravity will return it toward the closing position. I'Vhen the lifting means is fully depressed (as in Fig. 1) it is desirable that the valve should be partly open, so that the shorter leg of the siphon may be duly supplied with the water necessary to start the siphon. I therefore provide the stops or detents l which are engaged by the undersides of the valves and tilt them slightly as the disk it approaches its downward limit of movement, such stops or detents being angular pins in the present case projecting inwardly from the cylindrical wall of the leg 0.

The tube f limits the upward movement of the lifting means, it being abutted by the disk u at the end of the lifting stroke.

Any suitable inlet means, such as the nip ple having a valve 6 controlled by a float carrying lever 7 all of well-known construction, may be employed.

In apparatus of this character it is important to prevent as far as possible the admission of air into the siphon during the siphoning action, and especially during the first part thereof. In the present case, by therefore extending downwardly the part of the cap (1 through which the stem y passes an appreciable distance as a tube, 7, air is prevented from entering the siphon where it is penetrated by the stem until the siphon.- ing action is well under way, the tube forming in the meanwhile a perfect water seal and making it unnecessary to provide packing around the stem.

It will be understood that in the present instance the weight of the lifting means, lever 7) and the short arm 11% of: lever a sutliciently neponderates over the weight of the long arm n of said lever 7?, always to return the parts to the position shown in. Fig. 1 after each working stroke of the lifting means.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is The herein described mechanism for actuating the siphon-starting means of a flushing apparatus including, in combination, a vertical supporting wall, a pair of levers arranged parallel with and close to one vertical surface of said wall and side by side, close to each other, and a bracket secured to said wall and ailording a fulcrum support for the levers, one lever being ful crumed at one end and projecting downwardly at an incline and being adapted to be connected with said startii'ig means at its other end, and the other lever having a short arm. projecting substantially horizon tally in one direction from the fulcrum of said other leve and coupled with the fulcrum portion of the first lever and also having an angular power-applying arm projecting from the fulcrum of said otaer lever first up ardly and then in a direction relatively opposite to that in which the short arm projects, substantially as described.

In testimony whereof I allix my signature in presence of two witnesses.
