HORATIO BATEMAN AND DAVID OUMIVIING, JR., OF NEW YORK, N. Y.

IMPROVEMENT IN DRILLS FOR OIL AND OTHER WELLS.

Specification forming part of Letters Patent No. 52,@16, dated February 27, 1866.

To all whom t may concern:

Be it known that we, HoRA'rto BATEMAN and DAVID OUMMING, Jr., of the city, county, and State ot' New York, have invented a new and useful-Machine for Drilling and Pumping Oil and other Wells; and we do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being` had to the annexed drawings, making a part of this specification, in which- Figure l is a side view, Fig. 2 an end view, Fig. 3 a top View, and Fig. 4 a vertical sec tion.

The same letters refer to corresponding parts in thefdifferent figures, in which- A is the main frame, B the well, O the drilling-tool. and D the sliding frame. E is acam, having bearingsiii the ma'in frame. F is a Wheel7 having bearings in the sliding frame. G is a spring, one end of which is attached to the tools and the other end to a rope passing over a pulley on the top of the main frame. The other end ofthe rope is attached to the sliding frame by a rod which passes through the cross-head I-I. ,I isa spring secured to the main frame, haring arms the outer ends of which are attached to the lower end of the sliding frame. O is a bumper of any elastic material to deaden the blow of the sliding frame against the cross-head.

Mannerot'operation: The cam, being rotated by the crank X, comes in contact with the wheel F, thereby pressing,` down the sliding' frame and raising tl1e^tools. When the cani slips oli' from the wheel the tools fall, carrying up the'sliding frame, which is stopped by the bumper O/against the cross-head H. When the tools strike the bottom the jars N fall, with the velocity they obtain operating the spring G, which immediately recoils, therebyjarring the tools loose. The spring` I, being wound up to the necessary power by the lever t, draws down the sliding frame and assists in raising the/tools. In pumping, the pump-rods are substituted vfor the drilling-tools.

Vhat we claim,and desire to secure by Letters Patent, is

l. The cam E, in combination with the slidf ing frame D and the spring I, for the purposes specied.

2. In combination with the above,the spring Gr, for the purpose of operating the jars, substantially as described.

HORAIIO BATEMAN. ['L. s] DAVID OUMMING, JR. [L. s]
