PUMP-VENT CONTROL.

Application led pril 3,

To all whom t may concern.'

Be it known that l, IVAN GoNDnn, a citizen of the United States of America, residing at Bendon, in the county of Benzie and State of Michigan, have invented certain new and useful Improvements in Pump-Vent Controls; and l do hereby declare the following to be a full, clear, and exact description of t-he invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a pump vent control by means of which the water in a pump may be drained oii' above a certain level in the pump to guard against freezing and injury to the pump in cold weather, means being provided for opening the vent for such drainage and for closing the same when it is not needed as in warmer weather. My invention is directed to novel, simple and effective means for attaining this end, together with means for allowing such vent to be placed at different levels in different pumps, as may be required by different climatic conditions in diiferent latitudes where pumps are used.

With these and other objects in view, I have made the invention described in the following description, and illustrated in the accompanying drawing, in which,

Fig. l is a side elevation of a pump equipped with my invention.

Fig. 2 is an enlarged transverse horizontal section through the pump at y"the vent opening therein.

Fig. 3 is a fragmentary enlarged vertical Section through the vent control means, and

Fig. 4 is a fragmentary partial side elevation and vertical section of the manually loperable means for operating the vent control means.

Like reference characters refer to like parts in the different figures of the drawing.

In the construction shown, a pipe 1 depends from the upper port-ion 2 of the pump and in one side of said pipe above the pump valve shown, a vent opening 3 is made out through which water maydrain when the vent is open. A clamp comprised of twoparts 4 and 5 is located around the pipe 1 at the'opening 3,each half of the clamp having outwardly extendingears 6 through which bolts 7 may be passed to secure the clamp in place. Thepart 5 at one side has an eX-tension 8 with an enlarged recess 1() therein,

and a gasket 9 is located around such recess 'and bears against the pipe 1, preventing threaded extension thereto at one side," as i .indicated at 12 is attached to the projectingportion 8 of theclamp member 5, the extension threading into saidportion 8, as shown in Fig. 3. The casing at its opposite side has anoutlet extension 13, there being an opening 14 lthrough the casing 11 to let the water out when the passage is open. Avalve 15 with anopening 16 transversely through it is rotatably mounted in casing 11 said opening'l in one position, that shown in Fig. 2 alining with thepassage 14, while when turned to another position, thepassage 14 is obstructed. When open, the water may freely drain from'the pipe 1 from above the level of vent opening 3.

Thevalve 15 has a handle 17 at its upper end for turning the valve to different positions. Atube 18 passes over the handle and is connected therewith by acotter pin 19. The tube extends upwardly for a distance and at its upper end receives the lower end or" atubular rod 20 which may be adjustably connected at different positions to thetube 18. To do this,openings 21 are made at spaced apart points in opposite sides of thetube 18 and likeopenings 22 through thetubular rod 20, acotter pin 23 being passed through both the tube and rod whereopenings 21 and 22 come into conjunction. The change of position of the rod so as to have itsopenings 22 register withdifferent openings 21 eifects a different adjustment to correspond with requirements. The tubular rod extends upwardly throughplatform 24 on which the pump is mounted, and is formed with a., handle portion 201l at its upper end as shown.

It is evident that the pet cock may be closed or opened by turning therod 20 on grasping handle 20a thereof. The vent opening may be placed at any desired place in the length of pipe 1, the adjustability of the operating mechanism for the pet cock permitting this. It will be noted that the pet cock is tilted downwardly at an angle permitting a complete drainage'thereof and it is further apparent that by reason of the enlarged recess at 10, it is not necessary that pains be taken to bring the vent opening 3 and thepassage 14 in nice alinement.

The construction is simple, practical and etieient. The pump may be readily drained in cold weather, closed when any pumping is to be done and afterward opened, or lett closed all of the time after any danger of freezing is past.

The claims appended hereto define the invention and it is to be considered that any variations from the specific 'detail vshown that tall within the claims are compre- Ihended by said invention.

I claim:

l. In combination a pipe having a vent opening in one side, a clamp surrounding the pipe at said opening, one side of the clamp having a relatively large recess therein at the vent opening and having an youtlet opening in its side communicating with the recess, a pet cook attached tothe clamp in said outlet opening, said pet cock .including a rotatably mounted valve, a tube attached to the valve and extending upwardly therefrom, a rod telescoping into the upper yend o1" the tube and provided with an operating handle at its upper end, and means for connecting the rod tothe tube at a number of diflerent places to thereby adjust the combined length of the tube and rod, substantially as described;

2. In combination -with a pipe having a vent opening in one side, a clamp surrounding the pipe at said opening, there being a relatively large recess made on the inner side of the Clamp adjacent said vent opening, and said clamp having an outlet opening in its side communicating with the recess at the lower side thereof, a pet cook including a rotatably mounted valve attached at the opening in the side of the clampand extending outwardly and downwardly therefrom, a tube connected at its klower end k.to the upper end of said valve, a

rod telescopically received in the Lipper portion of the tube and Jformed at its upper end with a handle member, said rod having an opening therethrough near its lower end, and said tube having alned openings in its opposite sides at a plurality of spaced apart `points in its upper portion, and a pin for upper end of the tube and formed at itsr upper end with a handle member, andmeans to connect the tube and rod together at a number of dii'erent points to 'adjust the combined length of the rod and tube.

In testimony whereof I afiX my signature IVAN GONDER,v
