CUNTERBALANCING DEVICE FOR PUMPS. I
Specification of Letters Patent'.
Patented June 9, 1908.
To all whomfit 'may concern: l
Be it known that I, GEORGE C. WERNER, a citizen of the United States, residing at Beatrice, in the county of Gage andState of Nebraska, have invented a new and useful Counterbalancing Device for Pumps, of which the following is a specification.
This invention relates to counterbalancing devices for pumps and has for its principal object to provide a novel form of cushioning return spring for equalizing the operation of the pump and preventing damage from unnecessary jar where the device is employed in connection with a wind mill or similar operatin means.
A furt er object of the invention is to relieve the wind mill of all strain in the working of the pump, and to so arrange the structure that asupply of water can be had when a very light or fitful wind is blowing.
A still further object is to provide an improved mounting for the springs, and to employ springs which will permit full range of stroke.
. With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the s i'rit or sacrificing any of the adfthe invention.
In t e accompanying drawings :*Figure 1 is a sectional elevation of a pump attachment constructed in accordance with the invention. Fig. 2 is a plan view of the same, partly in section. Fig. 3 is a detail perspective 'view of one of the springs and its connections.
Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.
In carrying out the invention, two plates 10 and 11 are placed over the piston rod, these plates being provided with openings which will accommodate a rod ofc hndrical or flat form in cross section. T e lower plate 10 rests on and may be bolted to the pump head while the up er plate is suitably secured to the piston rodl.)
Secured to and extending u ward from the lower plate 10 are a number o vertically disposed posts 15, three of which are shown in the present instance, -thesev posts. passing through guiding openings formed in the u per plate 11 and serving as supports for he ical springs 16 which in practice will lift about twenty per cent. of the weight of the piston, piston rod, and column of water, and the springs are of suflicient length to accommodate the full stroke of the pump.
At suitable intervals the u per and lower plates are-connected by suitalble springs 20, each spring being preferably formed of spring wire centrally ent to form a loop 21, and thence extended outward, the two arms of the 'spring being coiled, and the arms thence turning at an angle to the former bend to the point where they are to be fastened to the upper plate 11, and at the upper ends are turned to form fiat hooks 22, the extreme ends of the hooks being bent into parallel relation with the* arms. The lower loop 21 passes through an eye formed in a keeper 25 that is held in place against the lower plate 10 by one of vthe hooks 15, the latter passing through an opening that is formed in the keeper, and said keeper is further confined by means of a suitable clamping bolt 27. The upper hooked ends of the spring are secured in place by pivoted cli s 30 which are connected to the u per p ate 11 by means of bolts 31, the bo ts forming pivots on which said clips may swing in order to accommodate the variation in angle of the springs when the latter are compressed and 'expanded.
One of the principal difficulties experienced in pump attachments of this nature is that the springs are either rigidly confined to the carrying plates and thus break at the oint of connection, or are so loosely confinedp that they become displaced during heavy and rapid work. In the present instance the springs are provided vwith hinged connections of such nature that there i-s no bending strain on the springs at the points where they are attached to the plates, there being sufficient freedom of movement to accommodate the slight variations in angle of the springs during the stroke of the piston.4
It is preferred in practice to em spring cushion which will lift a load o fifteen per cent. more than the whole weight of the piston and the column of water, so that no strain will be imposed on the wind mill during the up stroke, and during the down stroke the springs will act to graduloy a ten or all cushion the movement of the plunger ro and thus prevent the jar and noise incident to the operation of devices of this character as ordinarily constructed.
I claim 1. In 'a pump attachment of the class described, upper and lower plates, each provided with a centrally disposed opening for the passage of the plunger' rod 'of the pump, equ1distant vertically disposed standards carried by one of the plates, the other plate having equi-distantly spaced o enings for the passage of said standards, he ical springs surrounding the standards at points between the lates, and a lurality of sets of equi-dis tant f spaced coi ed springs having their termina arms secured to the outer portions of said lates.
2. n a pump attachment of the class described, the combination with a pair of plates, of a plurality of spaced standards carried by one of said plates, the opposite plate having openings for the passage of said standards, coiled compression springs mounted onthe standards between the plates, a series of keepers having openings for the passage of the standards, securing bolts for the keepers, a double spring having a central loop assing through the keeper, said spring being ent to form a pair of spaced coils, the terminal arms belng bent to form lat hooks, and a pair of spaced pivoted clips carried by the other plate and to which said hooks are connecte In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
GEORGE C. WERNER.
