PUMP.

Specification of Letters Patent.

Patented Jan. '7, 1913.

Application led November 6, 1909. Serial No. 526,585.

To all whom t may concern.'

Be it known that I, FRANK J. ZEC/HER, citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Pumps, of which the following is a specilication.

My invention relates to pumps and more particularly to that class of pumps known as suction pumps.

It has for its object, the provision of a pump which will be easily constructed, efficient in service, and more convenient than those of similar construction which have been heretofore in general use.

Ano-ther object of my invention is to provide a pump having an adjustable handle which may be disposed at an angle with the axis of the pump.

Still another object of my invention is to provide a pump adapted to permit the water remaining' in the suction chamber to flow back into the well in order to avoid freezinv.

fi still further object is, to provide means for obviating the usual leakage around the piston.

lith the above and other objects in view, my invention consists of such details of construction and combination of parts as will be hereinafter more fully described and speciiically pointed out in the claims.

In describing my invention in detail, reference will be had to the accompanying drawing in which like reference characters denote corresponding parts throughout the several views and in which,

Figure l is a view in side elevation of my improved pump, the dotted lines showing the position of the handle when in a raised posit-ion. Fig. 2 is a vertical section on the line A-A of Fig. l. Fig. 3 is a detail view showing the valve mechanism when the handle is in a lowered position, and, Fig. et is a detail view showing the valve mechanism when the handle is raised to its highest position.

l provide a base l, which is adapted to be suitably connected or mounted above the well or other source of supply. Erected upon this base and preferably in screwthreaded engagement therewith, is a cylinder 2, and suitably mounted upon the upper end of this cylinder is a water reservoir or chamber 3. This chamber has extending therefrom, a spout 4: of usual construction. Upon the upper closed end of the chamber 8, I provide an annular upwardly projecting flange 5, about which is received a collar 6, which is free to rotate around said annular flange. Screws 7 are provided, which are adapted to tighten the collar 6 so that itvmay be disposed in any position and prevented from rotating when such rotation is not desirable.

The flange 5 forms a cup-shaped chamber into which excess water from the main chamber of the pump is permitted to enter to constitute an overflow chamber for said main chamber 21, and thereby prevent splashing of the water out of the pump around the plunger rod. It also forms the support for the rotatably mounted collar 6, which as below described carries the standards supporting the operating mechanism for the pump.

Erected upon the top of the collar 6, are two standards 8, 8. 0n the rear edge of these standards suitable ears 9, 9 are provided within which is received a segmental gear 10, said gear being journaled in the outer ends of the aforesaid ears. Means are provided, such as a sleeve l1, formed on the segmental gear adapted to receive a handle 12 of usual construction. The gear is so j ournaled upon the upwardly projecting standards that when vthe handle is raised to its highest position, it will be beyond its center of gravity and will remain in the raised position as indicated in dotted lines at 12, instead of returning to its lowest position as is usual in pumps as formerly constructed. The purpose of this construction will be hereinafter more fully pointed out.

Extending through a suitable opening in the inclosed top of the collar 6, is the upper end of the piston rod 16, one side of which is provided with a rack 13 adapted to engage the teeth of the segmental gear. Bearing against the forward side of said piston is a friction roller 15 which is suitably journaled in outwardly projecting ears 14, formed on the standards 8.

ln the lower end of the cylinder 2, l provide an annular flange 22, which projects inwardly into said cylinder. A hole 23 is formed eccentrically of this flange. Hinged on one side of this hole is a valve 24, said valve being provided with an upwardly and outwardly projecting offset 25, which is adapted to be engaged by a stud 192l carried by the plunger 17 oli the piston 16.

0n the lower end of the piston 16 is provided the usual plunger 17, constructed with a cage or chamber 20, inclosing a suitable valve 19 adapted to open upwardly, said valve having-a downwardly projecting stud 19a.

16, 18 are annular packing rings provided for obvious reasons.

lThe operation of the valve system of my pump is as follows: `When the handle 12 is forced downwardly, the plunger 17 is drawn up, thus providing a partial vacuum in the chamber 21. This vacuum raises the valve 24:, which allows water to enter the aforesaid chamber 21. rl`he handle 12 is then raised forcing the plunger 17 downwardly. lfater enters the chamber 2O in said plunger, when the valve 19 is forced open and flows into that portion of the cylinder 2 which is above the plunger. lWhen the handle is again forced downward, the plunger raises the water above it and permits it to flow into the chamber 3 from whence it has its exit by means of the spout t. A continuation of this operation will give a steady flow of water from the spout, for the upwardly flared chamber 3 is sutliciently large and high above the outlet spout to provide a small head residue or accumulation of water, thus insuring an even flow, and also preventing the splash that usually occurs in open top pump constructions.

`When the pumping operation is stopped, the handle is raised to the position shown in dotted lines at 12. Because of the construction hereinbefore mentioned, the handle 12 will not return to its lowered position, but will remain in its raised position. `When so disposed, the piston rod 16 carrying plunger 17, is in its lowermost position, the lower end 19El of the valve thus engaging the offset portion 25 of the valve 23 forcing this valve open and permitting the surplus water in the chamber 21 to return to the well. Heretofore in pumps of this construction, the handle 12 would return to its normal position, thus permitting the valve 23 to return to its seat, where, in cold weather the valve would freeze, thus necessitating hot water being poured down the cylinder to thaw the valve from the seat. lt will be seen therefore that my construction has a great advantage over these former constructions inasmuch as the valves are all held open while the pump is not in use.

From the relation of the collar 6 to the annular flange, 5, it will be seen that l can turn the whole upper portion of my pump, including the handle, to any position without disturbing the location of the spout 4. ln other words, the handle 12 may be swung to either side or it may be disposed in frontof o-r in the rear of the body portion of said pump. The flange 5 also forms an overflow chamber for the main chamber 21 of the pump, since during the agitation of the water when pumping vigorously, that portion which would ordinarily splash around the piston rod 16 is accommodated in this auxiliary chamber formed by the flange 5 and collar 6.

From the foregoing, it will be seen that l provide a highly efficient pump, having several novel features of construction. The parts are few and simple and not likely to become broken or out of order. rlhe let back is an advantageous feature as will be readily appreciated and the same is true of the pivoted upper portion of the pump.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent is 1. ln a pump of the character described, a main water chamber, a plunger reciprocating therein, a fla-nge extending upwardly from the top of the main water chamber, a collar rotatably mounted on said flange and constituting therewith an overflow chamber for the main water chamber, a piston rod traversing both chambers and carrying at one end the plunger, standards supported by said collar and operating mechanism for the` piston rod supported by said standards above the flange of the main water chamber.

2. ln a pump of the character described, a main water chamber, a plunger and its valve, reciprocating in said chamber, a flange extending upwardly from the top of the main chamber, to form an overflow chamber therefor, a rack equipped piston rod traversing both chambers and carrying the plunger and plunger valve, a valve located at the bottom of the main chamber and controlling the inlet thereto, and a stud arranged on the bottom of the plunger valve and adapted to open the inlet valve to the main water chamber, when the plunger is in its downmost position in said chamber, an operating handle having a tooth quadrant at one end adapted to engage the rack of said rod, said quadrant being so mounted on the handle when in its highest position will be beyond its center of gravity whereby it is prevented from returning to its normal position, so adapting it to hold said plunger rod in its lowest position and the aforesaid valves open substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK J. ZECHER.
