CATCH-BASIN TRAP.

SPECIFICATION forming part of Letters Patent No. 788,721, dated May 2, 1905. Application filed November 21, 1904. Serial No. 233,712.

To all whom it In/ Ly concern.-

Be it known that 1, SYLvnsTER A. JOHNSON, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented a new and useful Catch-Basin Trap, of which the following is a specification.

This invention relates to catch-basins connected into drain-piping systems of various kinds, and has for its object to simplify and improve the construction and increase the efficiency of the traps employed in connection With apparatus of this character and to provide means whereby obstructions or clogs in the pipes maybe readily removed and without thenecessity of detaching any of the parts or excavating the earth above the pipes or the destruction of portions of the same.

With these and otherobjects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood thatthe invention is not necessarily limited thereto, as various changes in the shape, proportion, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacrificing any of its advantages.

In the drawings thus employed, Figurel is a sectional elevation of a catch-basin of approved forrn together with portions of the drain-piping with the improved trap in position thereon. Fig. 2 is an enlarged sectional View, and Fig. 3 is an enlarged front view, of the improved trap.

The improved device may be applied to any of the ordinary forms of catch-basins, represented at 10 with one section of the drainpiping 11 leading thereinto at one side and the other or discharge pipe, as at 12,1eadingtherefrom at another side, the catch-basin and drain-pipes being of the usual form.

At the catch-basin end of the discharge-pipe a trap-elbow 13 is coupled for annular rotation thereon, as by an annularsocket 1 1 on the pipe in which an annular flange 15 on the elbow is held by aclamp-ringlo. Formed upon the elbow adjacent to the flange 15 is another flange, 17 having spaced transverse apertures 18 for receiving an operating-hook 19 on the end of a rod 20, the latter being inserted therein through the opening into the catch-basin. By this simple means the elbow can be rotated to turn the discharge end of the elbow upward. The elbow can be rotated from the ground or from above the catch-basin to turn it into an upright position, as represented by dotted lines in Fig. 2, and afford easy access to the drain-pipe 12 for the removal of obstructions or clogs.

Any of the usual implements or devices employed for the removal of obstructions may thus be readily employed and without the ne eessity of removing any parts or the destruction of a portion of the piping, as frequently occurs when obstinate obstructions are encountered in drain-piping not having the improved attachment herein shown. If the obstruction will not yield to implements inserted through the inverted elbow, then the elbow can be readily detached by removing the clamping-collar 16 to expose the whole interior area of the drain-pipe for the introduction of stronger and more vigorously acting means, as will be obvious.

The device is simple in construction, may be readily applied and operated, and will be found very eflicient in practice and operative entirely from outside the catch-basin.

A tubular branch pipe 21 is inserted into the drain-pipe 12 adjacent to the basin 10, said branch pipe leading outwardly through the ground and being provided with a cap 22 for closing the outer end thereof, the inner end of the tube or pipe being bent at an angle to enter the drain-pipe at an incline toward the elbow 13. By this means if the elbow becomes clogged the obstruction can be readily removed by forcing a stream of water through the tube or inserting a suitable implement therethrough, as will be obvious.

As the majority of obstructions in sewerpipes occur at the trap-elbows and as most of them can be removed through the tubular member 21, it will be obvious that the tubular branch is an important feature of the invention and adds materially to its value and efliciency, and by providing a close-fitting cap for the upper end of the tube there can be no escape of gases therethrough.

Having thus fully described the invention, what is claimed is 1. A catch-basin having drain-pipes entering at one side and discharging at another side, and a trap-elbow mounted for rotation upon said discharge-pipe and extending into the basin, said trap elbow being provided with an annular flange having a plurality of transverse apertures whereby means are provided for operating said elbow from above the catch-basin entrance.

2. A catch-basin having drain-pipes entering at one side and discharging from another side, a depending trap-elbow mounted for rotation upon said discharge-pipe and provided with a terminal flange, a retaining-ring secured to the discharge-pipe and engaging said flange, a flush-pipe communicating with said discharge-pipe adjacent to said elbow and leading above the ground, and a closure for the intake end of said flush-pipe.

3. A catch-basin having drain-pipes entering at one side and discharging at another side, a trap-elbow mounted for rotation upon said discharge-pipe and extending into the basin, and a flush-pipe communicating with said discharge-pipe adjacent to said elbow and inclined to the longitudinal plane of the discharge-pipe, said flush-pipe extending above the surface of the ground and provided with a detachable closing-cap.

41:. A catch-basin having a drain-pipe entering at one side thereof and having a dischargepipe provided with a terminal socket communicating with the basin at the opposite side thereof, a trap-elbow rotata bly mounted in the socket of said discharge-pipe and extending into the basin, and a flushing-pipe communicating with said discharge-pipe adjacent to said elbow at an incline to the discharge-pipe and extending above the ground, and detachable means for closing said flush-pipe.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
