IMPROVEMENT IN RAILROAD WATER-CRANES.

Specification forming part of Letters Patent No. 142,150, dated August 26, 1873 application filed June 14,1873.

To all whom it may concern:

Be it known that we, HENRY S. OUBBER- LEY and DAVID MANN, of Bloomington, in the county of McLean and State of Illinois, have invented a new and useful Improvement in Railroad Water-Cranes, of which the following is a specification:

The object of this invention is to improve the cranes used at stations for supplying locomotive-tenders with water for their boilers at a distance from the water tank or reservoir, and connected with the same by means of a pipe laid under ground; and the invention consists in the improvement of railroad watercranes, as hereinafter described and claimed.

The accompanying drawing represents a vertical section of the crane, showing the parts in their proper position.

Similar letters of reference indicate corresponding parts. I

A is a frost-proof pit underneath the surface of the ground, upon the top of which the crane is supported. B is the supporting column, the base 0 of which is attached to the pit. D is an interior tube, to which the movable head E and discharge-pipe F are attached. This head rests on the top of the column, and can be turned thereon so as to deliver the water at any point. G is the valve-rod. H is the valve. I is the valve-chamber Within the pit. The seat of the valve is on the under side of the valve-chamber. J is the water-openin g to the valve-chamber. Across this opening is a bridge-tree, K, and around the valve-rod (below the valve) is a spiral spring, L, which rests on the bridge-tree, and bears upward with a constant pressure against the nut M, and holds the valve to its seat. The upper part of the valve-rod is a rack, N, the end of which extends up into the head, as seen at O. P is a pinion on a horizontal shaft, which shaft extends through the head, to the end of which (outside the head) the arm Q is attached. R is a screw by means of which the valve is operated. This screw is supported on the outside of the delivery-pipe by means of the lugs 12 'v. S is a bar which connects the screw with the arm Q. The bar S is connected with the screw by means of a stud-nut, T, attached to its end, through which the screw works and operates the pinion in the rack, and thereby opens and closes the valve. U represents a hand-wheel on the end of the screw, by means of which the screw is turned. By this means the valve is kept under perfect control, or opened more or less, as may be desired.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1 A railroad water-crane consisting of the column B, interior tube D, rack N, pinion P, arm Q, bar S, screw R, valve-chamber I, valve H, and valve-rod Gr, arranged to operate substantially as shown and described.

2. The screw It, in combination with the rack and pinion H 1?, rod G, and valve H, for the purposes described.
