IMPROVEMENT IN LIFT-PUMPS.

Specification forming part of Letters Patent No. 178,624, dated J 11116 13, 1876 application filed April 11, 1876.

To all whom it may concern:

Be it known that I, CHRISTIAN Fox, of Gap, Salisbury township, Lancaster county, in the State of Pennsylvania, have invented certain Improvements in Preventing the Freezin g of Lifting-Pumps, of which the following is a specification:

The object of this invention is to apply a simple and efficient arrangement to prevent the splitting or damage of frost in wooden lifting-pumps during winter, as well as to draw 011 the warm water standing in the stock during summer.

The accompanying drawing, with the letters of reference marked thereon, and a brief explanation, will enable those skilled in the art to make and apply this device, in which- A is to represent one of the common or encumber pumps now in common use through the country; B, the pump-bed; P, the spout. The device consists in the combined spout and levered valve, attached below the frostline to one side of the pump, bored to open through the attached spout L, covered by a valve, M, connected with an arm, J, and held by a pivot-bolt in a pair of brackets attached to the base-plate H, with which the spout is also cast in one piece. The valve is provided with stuffing, as also the plate, to prevent leaking. Said valve is held firmly closed by a coiled spring, K, connecting the end of the lever J with the spout L. In order to open the valve at pleasure, a wire, E, is attached to said valve lever J at I, and carried up through an opening, 0, in the pump-bed, held by a keeper, I), and the upper end attached to a headed pin, f, on an eccentric lever, F, acting upon a fulcrum-plate, G, affixed to the pump-stock at a convenient height vertically over the lowerdevice.

The operation is easily understood. By-

turning the eccentric lever F the wire-connection with the lever J opens the valve M, with which the lever is connected, and the Water above the spout L is discharged, and preventin winter, and equally desirable in the hot season during summer. Instead of pumping off the warm water in the upper part of the stock, it is readily drawn off. i

The eccentric lever, as well as the valvelever and supports, is easily cast and galvanized, and put on sale as anew article to the trade, which will evidently findfavor by all who use wooden lifting-pumps, so common in the country.

I am aware that several arrangements have been made with the same object in view, as in Patents No. 174,688 and No. 174,725, both dated March 14, 1876, which are operated by a rod or connected with the pump-handle. The valve is also connected to a straight lever, operating against the outer end of the spout, variously inserted into the pump-stock; but my valve acts direct upon the seat in the bracket-plate, and has a right-angled leverconnection over a spout, (or, rather, tr0ugh,)

closed-above only in front. Therefore What I claim as my invention is- The combination of the cam-lever F, fulcrum-plate G, and wire E, attached to a horizontal lever-arm, J, having a vertical valve,

M, attached, to set againstthe opening in a supportingbracket, H, which also supports an open spout, L, closed above'only in front, the whole arranged and operated substantially as herein shown and set forth.
