WWI two JOHN DONALD WOODWORTH, OF EAST MOLINE, ILLINOIS.

AUTOMATIC DRAININ'G DEVICE.

Application filed January 11,1917.

To all whom it may concern:

Be it known that 1, JOHN DONALD Wooo- WORTH, a citizen of the United States, residing at East Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Automatic Draining Devices; and I do de clare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to draining devices to be used more particularly in draining cellars, sewers, and other excavations without attention by the user.

This invention has for one of its objects the provision of a float-operated injector mechanism which will become operative when the water lever in the cellar, sewer, or other excavation rises to a predetermined point.

Another object of the invention is to provide a device of this character in which the various parts are arranged in a very neat and compact form.

A further object of the invention is to generally improve upon devices of this character by the provision of a simple, strong, durable, and comparatively inexpensive construction, and one which will be eflicient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and numerous other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described andclaimed.

In the accompanying drawings forming a part of the application, and in which similar reference characters designate like parts throughout the several views:

In the embodiment illustrated, the reference numeral 1 designates a vertical suction pipe adapted to be disposed in a cellar, sewer, or other excavation wherein the water to be drained ofl collects. To the lower end of this suction pipe 1 there is connected a strainer 2', the latter being made in two separable sections 3 and 1, the section 3 being threaded to the pipe 1 as shown, while the section 4 is perforated as at 5 and provided with legs 6 to maintain said strainer in slightly spaced relation with respect to the bottom of the cellar or other excavation. The sections 3 and 4 are circular in configuration and are provided with angular flanges 7 and 8 respectively between which is clamped a substantially flat plate 9, the central portion of which is provided with an opening 10. Seated upon the plate 9 and slidably mounted with respect to the open ing 10 is a valve member 11. When this valve member 11 is in its lowermost posi tion no water will pass from the strainer into the suction pipe 1, but as soon as the member 11 ismoved upwardly under the suction created in the pipe 1, the Water is allowed to pass through the strainer into'the latter.

The upper end of the suction pipe 1 is threaded to the laterally projecting portion 12 of a hollow housing 13.- This housing 13 is very similar to: a T coupling, and has its vertically disposed portion 1a arranged out of vertical alinement with the pipe 1. Threaded to the upper end of the vertically extending portion 14 of the housing 13 is a discharge pipe 15, while similarly secured to the lower end of the portion 14 is the stem 16 of an injector nozzle 17. It may well be noted that the injector nozzle 17 is disposed in vertical alinen'i'ent with the dischargepipe l5,. and that the latter is disposed outv of alinement with the suction pipe 1 and has its low-er end arranged in a plane spaced a short distance above the plane of the upper end of the latter. The reference numeral 18 designates a short length of pipe which is threaded to the upper end of a vertically extending portion of the housing 13 and is arranged centrally with respect to the discharge pipe 15. This pipe 18 has its lower end flared and disposed adjacent the free end of the nozzle 17 to coact with the same tically through the lower end of the portion 14 of the housing 13 and is formed into a valve casing 19, one side of which is con nected to one end of a supply pipe 20, the, purpose of which will be hereinafter de scribed.

Mounted within the valve casing 19 is a vertically slid'able valve 21, which, when in its uppermost position, seats itself against the upper end of the casing and prevents the fluid supplied by the pipe 20 from passing up through the stem 16 and out through the nozzle 17. lVhen the valve 21 is in its lowermost position it is opened, and such fluid may then be allowed to pass through the nozzle.

The reference numeral 22 represents a vertically extending stem connected in any suitable manner to the valve 21. This stem 22 projects downwardly through a packing box 23 arranged in the lower end of the easing 19, and is arranged alongside of and parallel with the suction pipe 1 as shown.

Slidable vertically upon a portion of the suction pipe 1 disposed below the plane of the lower end of the valve stem 22 is a float 24. This float is preferably in the form of a hollow cylindrical casing having a centrally arranged vertically extending tubular opening 25 therein. The top of the float 24 on opposite sides of the pipe 1 is provided with pairs of pivot ears 26, to which are pivotally mounted the lower ends of a pair of links 27.

The upper end of the links 27 are similarly connected to the free ends of the arms 28 of a forked lever 29. The other end of the lever 29 is pivoted to the upper end of a bracket 30 which extends from the side of the valve casing 19 adjacent the pipe 1. This bracket 30 extends in a substantially vertical direction and has pivotally connected to its lower end a link 31, the free end of which is pivotally connected to the intermediate portion of a lever 82. One of the ends of this lever 32 is connected to the lower end of a link 33, the other end of which is similarly connected to the lever 29 at a point spaced a short distance inwardly of its connection with the bracket 30. The other end of the lever 32 is pivotally connected with the lower end of the valve stem 22. By this construction it may be seen that whenever the float 24: is raised, the valve stem 22 will be lowered and consequently the valve 21 will be opened, thereby permitting water, steam, or other fluid under pressure to pass upwardly through the stem 16 of the nozzle 17, then out of the nozzle into the pipe 18. This causes a suction in the housing 13 and also in the pipe 1 suflicient to raise the valve member 11 and allow the water contained in the excavation in which the device is placed to be drained away. The movement of the float 24 is obviously caused by the change in the water level in the excavation, and it therefore follows that when this level is lowered to an amount ,where no harm will be done, the valve is closed.

From the foregoing description, taken in a As various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit of the invention, I do not wish to be limited to the construction herein shown and described other than that set forth in the appended claims.
