SPECIFICATION forming part of Letters Patent No. 256,126, dated April 11, 1882.

Application filed August 17, 1881. (No model.)

To all whom it may concern Be it known that I, WILLIAM H. GLoUn, of Detroit, county of Wayne, State of Michigan,

have invented a new and useful Improvement in Pumps; and I declare the following to be a full, clear and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference beinghad to theaccompanyingdrawings,which form a part of this specification.

My invention consists of the combinations of devices and appliances hereinafter set forth, and more particularly pointed outin the claims.

In the drawings, Figure l is a longitudinal section of a well, showing my device in position. Fig. 2 is a separate sectional view of the pump. Fig. 3 is a separate view, illustrating my outlet-valve mechanism and spring.

This invention is designed as an improvement upon the pump patented to me February My improvement consists, first, iu the com bination, with the plunger-rod of a double-acting pump, of a pivoted cross-bar, from the piv-- otal point of which depends a rigidly-attached pendulum lever, a similar pivoted cross-bar nearer the pump, and having one end connected with the plunger-rod, and .rods connecting the ends of the two pivoted cross-bars, so that each may turn on its pivot. By vibrating the pendulum-lever the outer cross-bar is caused topull alternately upon the rods connecting its ends to the inner crossbar, and an equalforce may be conveniently exerted by hand for operating the plunger-rod in both directions.

The invention consists, secondly, in the combination, with the pendulum-lever, of a handle pivoted to its lower end, and provided with a weight at one end for causing said handle to stand in a vertical position when not in use, as will be hereinafter fully described.

It consists, thirdly, in the combination,with the twooutlet-valves of adouble-actin g pump, of a single strip-spring confined at its middle portion, and having its opposite ends bearin g upon said valves, respectively, to hold them closed. By this construction I decrease the number of separate parts and lessen the manipulation necessary in setting up and taking apart the pump.

The invention consists, also, in anovel manner of supporting the spring in position to act properly upon the valves.

In carrying out my invention, A represents apum p cylinder or case divided by a close partition, A, through which passes with a close (it the cylindrical plunger B.

O representsinwardly-opening valve s,wl1ich I term the inlet-valves. A stem or stems, 0, project out through the case, and upon the exterior are provided with spiral springs Oflwhich serve to hold the valves snugly upon their seats when closed, but permit them to yield whenever a vacuum is produced within by movement of the plunger.

D represents the outlet-valves.

I) is a bridge, and D a strip-spring resting across and secured to the bridge, so that one of its ends will bear upon one of the valves and the other end upon the other valve, so as by its retraction to hold the valves snugly upon their seats when closed. I [ind the employ- .ment of a valve-spring in these cases to be of great advantage, since it prevents any leakage back from the discharge-pipe into the space back of the plunger as it is moving forward. I also deem the construction which enables me to use a single spring to govern both valves as very advantageous in the matter of simplicity and economy of structure.

E is the base-plate, which forms the lower end of the pump-chamber, and is provided with legs, by which the structure may be secured to a board located in the bottom of the well or cistern, yet be raised sufficiently high to enable the pump to take its water directly through the bottom of the chamber. This construction is ofvalue, inasmuch as it raises the pump high enough to avoid danger ofdrawingin sediment or grit from the bottom of the well, and makes also is provided with a pintle, upon which swings the pendulum-lever H. This lever is provided at its upper end with a cross-bar, H, which is rigidly secured thereto.

1 isarod or strap, which may extend down and be connected directly with the pump-shaft B, and thus communicate motion to the plungerB as the pendulum is swung to and fro. I prefer, however, to provide another pivoted crossbar, H preferably near the pump-chamber, and connect the respective ends of the said cross-bars with each other by straps or rods I I, which, if the well is deep, may he stayed at one or more intermediate points bystay braces or guides 1 through which the rods or straps may loosely pass, and thus be steadied. By

employing the two cross-pieces H and H thestrains upon therods I and I are always strains of extension. They do not therefore have to be so stiff and strong as would be required if they were obliged, as in the'case of a single rod, to sustain alternately a pull and a thrust. The rods may be secured to the cross-pieces either by rivets or by bolts, as may be desired.

J is a handle-pivoted to the lower end ofthe pendulunrlever, by which the same can be readily operated, and I prefer to provide a connterpoise-weight, J, at the opposite sides of the pivot, which shall be suffioiently heavy to lilt the handle to a vertical position when it is not in use. By this means the handle is always in the best place for convenience, and yet is always up out of the way when not in use.

K is an air-chamber, which, if closed, puts the apparatus in condition for use as a forcepump by which to throw water to a distance as, forinstance, through a hose; but when open it simply serves to give a little head to the water above the discharge-point, thus causing it to discharge with a regular stream.

The plunger B may, if desired, be made hollow and be filled with a wooden plug, thus reducing its weight; or, instead of filling it with wood, it may simply be cast hollow, but closed at all points but its point of attachment to the pump-shaft 13, thus accomplishing the same end.

Instead of a rigid slotted stay, 1?, there may be, if desired, located at this point simply an intermediate pivoted bar, like the bar E the ends of which may be connected with the straps I and I.

L is a shelf, attached in any suitable manner to the pump; but I prefer to attach it by means of a clamp, L, for the reception of a vessel. This shelfis perforated, that water may not be retained on it, and I also prefer to make it a swinging shelf, that it may be out of the way when not in use.

What I claim is- 1. The combination, with the plunger-rod of a double-acting pump, of the upper pivoted cross-bar, having the pendulum-lever rigidly secured to its pivotal portion, thelower pivoted cross-bar, having one end connected with the plunger-rod, and the rods connecting the ends of said pivoted cross-bars, substantially as described. ,7

2. The combination, with the pendulum-lever, of a handle pivoted to its lower end and provided with a counterpoise-weight for causing the handle to stand vertical when not in use, substantially as described.

3. The combination, with the two outletvalves, of the single strip-spring confined at its middle portion, and having its opposite ends bearing upon said valves, respectively, to hold them closed, substantially as described.

4. The combination, with the two outletvalves of a double-acting pump and the intermediate bridge, I), of the fiat strip-spring D having its middle portion secured to said bridge and its opposite ends bearing upon said valves to hold them normallyclosed, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

WILLIAM H. CLOUD.
