GILBERT M. COLE, OF FOLSOM CITY, CALIFORNIA.

Specification forming part of Letters Patent No. 33,294, dated September 17, 1 861.

,To a/ZZ whom, it may concern:

Be it known that I, GILBERT M. COLE, of Folsom City, in the county of Sacramento and State of California, have invented a new and Improved Mode of Turning Locomotives on Turn-Tables; and I do hereby declare that the following is a full and exact description of the said invention, reference being had to the accompanying drawings, making part of this specification, in Which- Figure l is a plan of a turn-table illustrating my said invention. Fig. 2 is a plan of the bed with the table proper removed.

The nature of my invention consists in attaching to the turn-table a small pair of steam-cylinders C C, Fig. 1, and the accompanying steam-chests, whose connecting-rods are to operate the crank-shaft S, which, in con-` nection with the cog-work A and A', will cause the table to revolve. Steam is to be communicated to said steam -cylinders from the locomotive, when on the turn-table ready to be turned, by means of a pipe leading from the dome or steam-chamber of the locomotive to point at the rear end of the locomotive, hich will then be at a central part of the `rn-table and convenient to be attached to ne pipe leading to said cylinders at the points P and P. The branch pipes leading from P arf? P to said cylinders uniting are cach fur-` nished with valves at V and V,so that when steam from the locomotive is thrown into one branch pipe at P the valve V closes andprevents the steam from escaping' at P', and when steam is thrown into the other branch pipe at P the valve V closes, confining the steam to the pipe leading to the cylinders, a portion of the branch pipes at P and P being jointed or flexible to facilitate attaching it to the pipe from the locomotive, one pipe only being required to conduct steam from the locomotive to either of said branch pipes, as the locomotive shall go on the turn-table at one end or the other. By my plan the large segment cog-wheel A is to be cast on the edge of the cast-iron track upon which the wheels of the turn-table roll round, thereby combining two sets of large castings, and is fastened to the foundation, (see Fig. 3,) the Wheels of the turn-table rolling between the dotted lines.

I am informed and believe that the work of turning turn-tables is done by other power, and principally by 'man-power.

I That I claim is- The application of steam from the locomotive in the manner described to do the Work of turning turn-tables, thereby saving a vast amount of labor and time, and in this connection the combination of the great segment cog-wheel and the track upon which the wheels of the turn-table roll by casting the said track with the cogs on the edge of it, thereby dispensing with one heavy set of castings and fastenings, all substantially in the manner and for the purposes set forth.

GILBERT M. COLE.
