FLUSH-TANK."

'srEcIrrcA'rI'oN forming part of' Letters Patent'No. 627,778, dated June 27, 189e. Application tiled November 2, 1898. Serial No; 695,263. (No model.)

To' @ZZ whom, t may concern.-

Beit known that I, WILLIAM MACKINTosH, of New York, (Brookly'm) in the countyof Kings and State of NewYork, have invented certain new and useful Improvements in y Flush-Tanks; and I do hereby declare that the tingly discharging into the sewer a quantity of Water to clean the same.

The invention relates more specifically to a construction and arrangement in devices of this character which is designed to permit the section of the sewer between the Yflush-tank and the next manhole to be readily inspected thoughout the length of the same and, if nec'- essary, to be cleansed of any substance lodged therein.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure l is a central vertical section of a flush-tank made'in accordance with my invention. Fig. 2 is a section taken on line 2 2 of Fig. l. Fig. 3 is a section taken on line 3 3 of Fig, l.

In said drawings, A designates the reser- Voir or tank proper, A a feed-pipe leading from any suitable source of watersupply,

, upwardly at its end remote from the receiving-limb to form `a deep seal C2.' Said discharge-limb opens at its end remote from the receiving-limb C into the bottom of the tank A and is in communication withv the sewer B, so that when the siphon is brought into op'- eration the water will be drawn out of the tank through said sewer. The connection between the discharge-limb of the sipho'n and the sewer consists in this instance of a short section of pipe D, into which the discharge-pipe opens and is arranged to discharge into the mounted over' the outer end of the dischargelimb, said section being provided in its under side with an opening, through which the outer end of the discharge-limb projects, and supportedupon the discharge-limb by means of an annular flange c thereon. The purpose of loosely mounting the section D upon the dis-` charge-limb is to enable the same to be rotated so as to be adjusted angularly thereon to provide for any inaccuracies of setting when the apparatus is being put in place. Said connecting-section is herein shown .as of oblong or pear shape in plan, withits smallerend projecting into the sewer-pipe, and a water-tight connection is provided between said parts'by cement or the like. Said connecting-pipe Dis provided in the end thereof opposite the sewer-pipe B with an opening,which is normally closed by means of a removable cap DEV Said opening is provided for the purpose of giving an inspector a clear range of vision through'Y said connecting-pipe and the sewer to the next manhole for the pur` the open end of' the connecting-pipe in any suitable manner permitting it to be readily removed.` As herein shown, the inner end of said pipe is provided with an enlarged annular recess, within which the, cap fits,

' sewer. Said section will preferably be loosely and the 'cap will be secured therein by the use of cement or the like. In order toV preventthe longer Inember of the dischargelimb from obstructing the View through the said connecting-pipeand the sewer, saidsi phon is arranged with the two members of said discharge-limb in a plane practically perpendicular to the central axis of the sewer- Ioo pipe or with the longer member thereof at one side of the connecting-pipe D. With this arrangement the intaking-limb of the siphon will be located at one side of the tank. The angular position of the siphon to the sewerpipe B need not be exactly as herein shown, it being only necessary that the inner member of the discharge-limb be swung laterally away from its usual position within the tank, so as to be out of line with the opening in said connecting-section D, and therefore will not obstruct the View thereof through said section. Preferably the tank willbe provided in the bottom thereof with a centrally-arranged trough-likedepression extending across the same, which is adapted to receive the end of the sewer-pipe and connecting-section D. The provision of this depression enables the siphon to be located in the tank, with the lower end of the receiving-limb closely adjacent to the bottom of the tank, so that the tank may be as nearly drained as in the ordinary construction, notwithstanding the fact that the dischargedimb vof the siphon projects into the tank. The depression will preferably be of such size as to entirely receive the sewer-pipe B andthe connecting-section D.

"In the operation of the siphon the tank will be emptied to the level of the lower end of theintaking-arm of said siphon, and when it is desired to inspect the section of sewer beyond the flush-tank and between the same and the next manhole the supply-pipe A will be cut ed from the tank and the cap D, removed from the connecting-section, and the water remainingin the tank will be discharged through said connecting-section and sewer B. `The inspector will then have a clear View through the connecting-section and the portion ofthe sewer betweenthe flush-tank and thenext manhole (or lamp hole or passage; incase the sewer be provided with the same) and will have suflicient room to insert a cleaning apparatus into the sewer to remove any obstructions therefrom.

Heretofore means for inspecting or cleaning a sewer in its part adjacent to the iiushtank has been afforded by providing a manhole located near the lushtank, by meansv of which access may be had to the end of the sewer nearestthe Hush-tank and that part of the sewer leading from the Hush-tank can be both inspected and cleaned. Such manhole permits the inspectionand cleaning of the part of the sewer between the flush-tank and the manhole located at some distance therefrom or between the Hush-tank and the main or receiving sewer into which the pipe from the hush-tank discharges. In other cases -a lamp hole or passage has been provided by means of a vertical pipe, which is tapped into the sewer adjacent to the flushtank and extends upwardly to the surface of therground. In the use of such lamp-hole a light` is lowered through the pipe into the sewer, so that the same may be inspected from the next adjacent manhole or from a main sewer, as the case may be. When a manhole is made near the hush-tank, it venables the part of the sewer leading from the tank to be both inspected and cleaned, and

.when a lamp-hole only is employed it perthe end ofthe sewer-pipe and the connec-V tions between the same and the siphon are located, together 'with the adjacent section of the sewer-pipe, this operation obviously involving a very considerable amount of work and expense.

An important advantage gained by the use ofthe improvements hereinbefore described is the avoidance of the necessity for such a manhole or lamp-hole "at a point near the flush-tank and the consequent saving of the cost of constructing such manhole or lamphole. In' other words, my improvement provides at a small cost a means by which is saved the much larger expense of providing a lamp-hole or manhole at the flush-tank. Moreover, my-improve'ment provides all the advantages gained by theuse of a manhole, because allowing the cleaning as well 4as the inspection of the end of the sewer nearest the iiush-tank, it being of course understood that the cheaper expedient of the lamp-hole provides for inspection only and does not afford means for readily cleaning the sewer.

It will be understood that my improvement may be employed in connection with other forms of flushing apparatus than that herein shown--as, for instance, the discharge-limb of the siphon may discharge directly into the sewer instead of a connecting-pipmas shown. In this event the rst sectionof the sewer-pipe will be provided with a removable cap and will be provided in its under side with an opening for the insertion of the discharge-limb of the siphon.

I claim as my inventionl. The combination with a tank or reservoir, of a siphon and a discharge-pipe leading from the interior of said tank and connected with the discharge-limb of said siphon, said pipe being closed by means of a removable closure at its end into which Vthe siphon discharges.

2. The combination with a tank or reservoir provided in its bottom with a trough-like depression, of a discharge-pipe leading from said tank and located in alinement with said lio depression, and a Siphon, the discharge-limb of which is connected with said pipe, Said pipe being closed by means of a removable closure at its end into which the Siphon dis charges. l 3. The combination with a tank or reservoir, of a Siphon, a discharge-pipe leading from the interior of said tank, and a removable Section for connecting the dischargelimb of the Siphon with the discharge-pipe, Said connecting-section being provided with a removable closure located opposite to or in alinement With thediSoharge-pipe.

4. The combination with a tank or reservoir, of a Siphon, a diScharge-pipe lleading from the interior of Said tank and a connecting-section rotatively mounted on the outer end of the discharge-limb of the Siphon and having a discharge-opening which is connected with said pipe, Said connecting-Section being provided with a removable closure forming its side or Wall opposite the dischargeopening therein. v

5. The combination With a tank or reservoir, of a Siphon and a discharge-pipe leading laterally from Said tank and connected with the discharge-limb of Said Siphon, said pipe being closed by a removable closure which iS located in alinement with the pipe and the tank being provided with an unoccupied Space which is also in alinement with Said pipe, affording -means by which the pipe may be visually inspected from the interior of the tank when Said closure iS removed.

1n testimony that I claim the foregoing as my invention I affix my Signature, in presence of two Witnesses, this 27th day of October, A. D. 1898.
