AUTOIVIATIC GATE FOR FLUSHING SEWERS.

SPECIFICATION forming part of Letters Patent No. 614,675, dated November 22, 1898.

Application filed January 1l, 1897.

Z'o @ZZ whom t may con/cern:

Be it known that I, STEPHEN S. TILTON, a citizen of the United States, and a resident of the city and county of San Francisco andv State of California, have invented certain new and useful Improvements in Automatic Gates for Flushing Sewers; and I do hereby declare that the following is a full, clear, and eXact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use,and practice the same.

Myinvention relates to that class of devices which are placed across sewers or flumes for holding back the water until a certain quantity is accumulated and the desired pressure is obtained and then released instantaneously through an automatic gate for the purpose of flushing away all debris which may have settled at the bottom of the sewer.

The object of my invention is to produce a device which is simple in construction, effective in operation, and convenient in manipulation, so arranged that its movements are automatically controlled by the iiow of water passing through the sewer; and it consists, first, of a rotating gate constructed in the shape of a fanning-wheel provided with a suitable frame mounted centrally upon a wooden frame placed across the sewer; secondly, of adjustable means by which both the wooden frame and the frame of the rotating gate can be made water-tight; thirdly, to provide adjustable means to stop and release the gate when desired.

In the accompanying drawings, which form a part of this specification, Figure 1 is a longitudinal section of an ordinary sewer broken away, showing a vertical section of my device. Fig. 2 is a vertical section of the sewer, taken from dotted line 1 1 of Fig. 1, showing a front elevation of my device. Fig. 3 is a section taken from line 2 2 of Fig. l, showing particularly the construction of one of the mitering corners of the wooden frame.

Similar letters of reference refer to similar parts throughout the several views of the drawings.

A represents the sewer, within which the wooden frame of my invention may be placed across it at any point desired for the purpose of flushing away all debris deposited therein.

Serial 'No` 618,879. (No model.)

This frame consists of two vertical side pieces B,whicl1 maybe conveniently called wings,77 hinging to a lower cross-piece C, as particularly shown in Fig. 3, and Ct are bolts by which the mitering ends of the wings and the crosspiece are secured together and rendered water-tight. The wings and the cross-piece are cut to fit the inner curve of the sewer and arearranged in such a manner as to form a central square aperture, within which my device rotates.

Between the outer edge of the wings and the crosspiece and the inner wall of the sewer a rubber strip b (or other elastic material may be used, if desired) is preferably placed within a depression or groove cut upon the wings and the cross-piece and project outwardly to form a iieXible joint for the purpose of rendering that part of the wooden frame and the inner wall of the sewer watertight. This feature is plainly shown in the drawings. In Fig. 2 a port-ion is broken away to show the rubber placed into the depression.

The inner upper end of the wings are cut inwardly to provide suitable shoulders for the toggle-joint D, which stands centrally above the square aperture previously described, and in a line above the wings and the toggle-joint is a beam E, rigidly secured across the sewer.

Between the beam and the upper ends of the wings just described I place wedges c for the purpose of forcing the wings downwardly, while wedges d, placed between the togglejoint and the beam, force them sidewise until the joint between the win gs B and the cross-piece C and the inner wall of the sewer become perfectly water-tight.

The cross-bars F are removably secured upon the upper sides of the wings by means of brackets e and serve to keep the wooden frame in position and likewise the togglejoint in proper place. AThe beamE is also provided withguiding-plate G for the purpose of keeping the wedges d in position.

'The various wedges, as shown in the drawings, are provided with the usual groove and sliding rib f between their mitering edges to prevent them from shift-ing away while forcing them toward each other. j

The frame H is mounted upon the front elevation of the wings B and the cross-piece ICO C and may be secured in any suitable manner; but I prefer to carry out this feature as shown in the drawings, where it 'will be seen that the frame is provided with outwardlyprojecting cars having notches g, through which bolt h, rigidly secured to the wings and the cross-piece, passes. These bolts are provided with a knuckle-joint, so that they can be quickly removed from the frame, and the thumb nuts t' serve to tighten the frame against the wings and the cross-piece. The bearing-faces of this frame are provided with suitable packing j, so that a water-tight joint can be obtained.

Suitably mounted within the frame II is the rotating gate I, which, acting as a dam, controls the iiow of water passing through the sewer. This gate is preferably constructed in the shape of a fanning-wheel with four rectangular blades.

Rigidly secured across the sewer and back of the gate is a beam J, upon which the angular plate K is ad justably secured crosswise by means of double-ended sliding bolt Zt'.

Pivoted to the forward end of the angular plate just described is lever Z, which serves as a stopper for the rotating gate and controls its movements, while lever m is pivoted to the rear end of the angular plate and is adapted to force downward the rear end of lever Z for the purpose of releasing the gate I when desired.

The rear end of lever lm. is provided with an adjustable iioat, which consists of ball L, provided with stem n., having a screw-threaded portion for the purpose of adjusting the same.

The guiding-pin o, secured to the angular plate K, prevents the lever Z from going beyond its intended position.

The operation of my invention may be described as follows: N'Vhen all the various parts of my invention are placed in position within the sewer across the water-course and the dierent screws and wedges forced within their respective places until the structure becomes water-tight, the rotating gate I is then held rigid in position by means of lever Z, thus forming a dam to that portion of the sewer. The course of the water being stopped, the same will naturally dam up against the gate and cause the float secured at the rear end of lever m to rise with it, thus forcing the forward end of the lever to press down-4 ward upon the rear end of the lever Z and cause thereby its forward end to swing upward, thus releasing the gate I. The gate being free from any obstruction, the pressure beyond forces the same to rotate, thus allowing a large volume of water to pass instantaneously through the central aperture of the wooden frame and removes by its natural force any debris which may be settled at the bottom of the sewer within the vicinity of my device. As soon as the water depresses the float, with lever m, will naturally drop downward and release thereby 1e ver Z. The forward end of this lever being heavier beyond its pivotal center will drop also downwardly to its normal position and slide upon the projections p of the other blades while the gate is being rotated until the former blade is reached. Thus the apparatus is ready for similar operation.

Believing l have produced a valuable improvement in automatic gate for iiushing sewers and having described the same,wl1at I claim, and desire to secure by United States Letters Patent, is-
