IMPROVEMENT IN ADJUSTABLE CLAMPS FOR PUMP-RODS.
Specification forming part of Letters Patent No. 215,030, dated May 6, 1879 application filed October 7, 1878.
To all whom it may concern:
Be it known that I, ALEmNnER WALLACE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Adjustable Clamps for Pump-Rods; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
My invention consists in providing the clamp for pump-rods with a gateway, whereby the pump-rod can be placed in the clamp and be removed from it by a lateral movement of the rod, said rod being held in the clamp by means of a wedge and a gib-key, the latter furnished with screw-threads and screw-nuts for drawing down the gib-key, thereby causing the wedge to be forced against the pump-rod for holding it firmly in the clamp, which is pivoted and suspended to the walkin -beam by means of a hanger.
To en able others skilledin the art with which my invention is most nearly connected to make and use it, I will proceed to describe its construction and operation.
In the accompanying drawings, Figure 1 is a top view of my improvement in adjustable clamps for pump-rods. Fig. 2 is a side elevation of the same, and Fig. 3 a front elevation of the same. Fig. 4 is a vertical section of the same at line y of Fig. l. Fig. 5 is an end view of the walking-beam with the adjustable clamp secured and pivoted thereto, and Fig. 6 is a side elevation of the same.
In'the accompanying drawings, A represents the clamp, which is provided with a gateway, B, the side walls of which are recessed for the reception of the wedge and gib-key D, the lower end of which is furnished with screw-threads e and screw-nuts f and g, for drawing downward the gib-key D,thereby forcing the wedge 0 against the pump-rod B, for holding it in the clamp A. The clamp A is provided with trunnions h h, which are fitted in bearingsi of the rods j j, which pass through openings in the cross-bar k, and are furnished with screw-threads and screw-nuts, as shown at l in Figs. 5 and 6, for drawing up the trunnions h h into the recesses min the under side of the walking-beam A.
The operation of my improvement is as follows: The pump-rod is placed in the clamp A by entering it sidewise through the gate B.
The wedge (l is then placed against the pumprod, and then the gib-keyD is placed in position in its recess, as shown in the drawings. The operator screws up the screw-nutf, which will draw down the gib-key, which will force the wedge 0 against the pump-rod B, and hold it in a fixed position at any desired point on the rod.
The advantage of a clamp constructed as hereinbefore described consists in the facility and ease of removing the rod from the clamp by a lateral movement of it through the gateway B, and in the efficiency of the means used for holding the rod in a fixed position in the clamp; also, in the means for pivoting and suspending the clamp to the walking-beam.
Having thus described my improvement, what I claim as of my invention is-- 1. The adjustable clamp A, having a gateway, B, in combination with a wedge, O, and gib-key D, furnished with a screw-nut, f, substantially as herein described, and for the purpose set forth.
2. The adjustable clamp A, having a gateway, B, and trunnions h h, in combination with a hanger consisting of the bar 7c and rods j j, furnished with bearings a 'i for the trunnions h h, and screw-nuts for drawing the said trunnions into recesses m m in the under side of the walking-beam A, substantially as herein described.
ALEXANDER WALLACE.
