ATTACHMENT FOR PUMPS.
SPECIFICATION forming part of Letters Patent No. 614,681, dated November 22, 1898.
Application filed Tune 30, 1898. Serial No. 684,868. (No model.)
To all whom it may concern/.-
Be it known that we, CHRISTOPHER R. WEST and ROBERT COWAN, citizens of the United States, residing at Primghar, in the county of OBrien and State of Iowa, have i11- vented a new and useful Attachment for Pumps, of which the following is a specification.
Our invention relates to attachments for pumps, and particularly to the pump-rods of windmill pumping mechanisms and the like,
- the object in view being to provide an equalizing device whereby the downstroke of the pump-rod will exert approximately as much resistance to the movement of the operating mechanism as the upward movement of said rod to produce uniformity in the rotation of the Wind-wheel, and thus adapt the apparatus to be operated by a comparatively light wind.
Further objects and advantages of this invention will appear in the following description,and the novel features thereof will be particularly pointed out in the appended claims.
In the drawings, Figure l is a view of an equalizing device constructed in accordance with our invention applied in the operative position to a Windmill pump-rod. Fig. 2 is a detail view in perspective of the same. Fig. 3 is a detail view of one of the members of the adjustable collar. Fig. is a detail view of the stationary collar. Fig. 5 is a detail sectional View of the adjustable collar and the contiguous portions of the equalizin gspring and pump-rod.
Similar numerals of reference indicate corresponding parts in all the figures of the drawings.
The equalizer embodying our invention consists, essentially, of an expansion coiled spring l, arranged exteriorly Of and concentric with a pump-rod 2 of the ordinary or any preferred construction, said spring being interposed between a fixed collar 3, preferably bolted to a frame member at of the windmilltower, and an upper collar 5, which is adj ustably secured to the pump-rod. The stationary or lower collar 3 consists of a plate provided with suitable bolt-openings and an upstanding hub 3a, around which the lower end of the equalizin g-sprin g iits to prevent lateral displacement thereof and contact with the pump-rod, which obviously reciprocates in the bore of said collar. The upper collar is of sectional construction and comprises separable members, of which one is illustrated in detail in Fig. 3, having radial extensions or ears 6, provided with registering boltopenings engaged by adjusting-bolts 7, the contiguous faces of the collar members being normally spaced apart to allow for inward adjustment to secure the desired clamping action upon the pump-rod to lock the collar firmly at the desired adjustment thereon. In order to increase the efliciency of the engagement of said adjustable collar with the pump-rod, we preferably provide the members of the collar, on the bottoms of the registering channels 8 thereof, with transverse ribs or detents 9, which are adapted to engage transverse'depressions or grooves 10, formed in the opposite side surfaces of the pump-rod. In other Words, the adjustable collar and pump-rod are provided with interlocking faces, of which the collar members preferably carry the projections, while the pump-rod is provided with the depressions to enable the collar members to be adjusted upon the pump-rod to secure the desired tension of the equalizingspring and to be secured effectively at the desired adjustmentby the simple tightening of the bolts 7, which serve as the connection between the collar members. It will be understood that this adjustment of the equalizing-spring is designed to compensate for different weights of pump-rods and depths of wells, diameters` of cylinders, dac. Under ordinary circumstances the downstroke of a pump-rod, as when no load is being carried, is facilitated by the weight of the pump-rod, and hence little resistance is offered to the movement of the Wind-wheel, Whereas during the up- Ward stroke of the pump-rod the wind-wheel must overcome the resistance due not only to the Weight of the column of Water, oil, or other contents of the pump-cylinder, but the weight of the pump-rod and attachments. By employing an equaliZing-spring of sufficient tension to partly counterbalance the resistance during the upward movement of the pump-rod we not only assist the Windwheel in the elevation of the pump-rod and the column of liquid, but resist the down- IOO Ward movement thereof, and thus it is possible to accurately equalize the resistance offered during the up and down strokes of the pump-rod, (increasing the doWnstroke proportionately to the reduction of the upstroke,) and thus enable the wind-wheel to operate with a much less Wind-pressure than would be necessary under conditions wherein all the resistance is during the upstroke of the pump-rod.
The construction embodying our invention is simple and may be applied with facility to the pump-rod of any Windmill pumping mechanism now in common use Without altering the construction of the usual pumping mechanism.
Having described our invention, what we claim isl. The combination with a wind mill pumprod, of an equalizingspring coiled concentrically with the pump-rod, a stationary seat or collar for the lower end of the spring, a sectional upper collar fitted upon the pumprod to constitute a seat for the upper end of said spring, and having its members provided with faces interlocked with contiguous lfaces of the pump-rod, and means for relatively adjusting the members of said upper collar to cause the interlocking engagement of said faces, substantially as specified.
2. The combination With a Windmill pumprod, of an equalizing-spring coiled concentricallywith the pump-rod, a stationary seat or collar for the lower end 'of the spring, a sectional upper collar iitted upon the pumprod to receive the upper end of Athe spring, said upper collar comprising separable members, having registering channels provided at their bottoms with transverse projecting ribs,to engage opposite depressions or grooves in the side surfaces of the pump-rod, and ad` justing-bolts connecting the collar members to vary the relative positions thereof, substantially as specified.
3. The combination with a Windmill pump rod, of an equaliZing-spring coiled concentrically with the pump-rod, a Vlower stationary seat for the spring consisting oi' a plate pro vided With means for attachment to a supporting-frame, and having a centrally-bored hub of an exterior diameter to fit Within the contiguous end of said spring and hold the latter out of contact with the pump-rod, a sectional upper collar fitted upon the pump rod and engaged with the upper end of said spring, said upper collar having separable members arranged in contact With opposite side surfaces of the pump-rod, and adjusting devices connecting said members to secure them in frictional contact with the pumprod, substantially as speciied.
In testimony that We claim the foregoing as ourown we have hereto affixed our signatures in the presence of two Witnesses.
