EDWARD D. YATES, OF PHILADELPHIA, PENNSYLVANIA APPARATUS FOR PUMPl NG OIL-WELLS.

SPECIFICATION forming part of Letters Patent No. 226,948, dated April 27, 1880.

Application filed May 28, 1879.

To all whom it may concern:

Be it known that I, EDWARD D. YATES, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Pumping Oil-VVells and analogous uses, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a perspective view, showing my invention in operation; Fig. 2, a plan view, and Fig. 3 a mode of arranging my oscillating wheels.

The object of my invention is the economizing of the power requisite to pump non-flowing oil-wells.

Prior to my invention each well required an engine or water-wheel, or, at the most, two or more wells were connected with the same motor, either by connecting their walking-beams with the same line of reciprocating rods or by means of pulleys. The dead-weight of the pumping-rods and appliances of each well was by this method thrown directly on the motor, and its limit of practicability soon reached. There were, it is true, some devices extant by a proper adjustment of which a number of wells could be made to balance each other, but their expensive and complicated construction forbade their general use.

In my improved process I connect the motor not with the reciprocating rods directly, but with an oscillating wheel, which (reference being now had to the drawings) is marked B, the motor being represented at A. This connection is effected by means of the rods a a, in the manner shown.

To suitable projections on the wheel B, such as are shown at b b, I attach the lines of reciprocating rods 0 C, so that the dead-weight of the pumping apparatus attached thereto may be thrown upon the wheel B in such a manner that one half of it shall tend to pull the wheel in one direction and the other half tend to pull it in the other direction. The wheel being thus in equilibrium, the only work thrown upon the motor A, beyond overcoming the inertia and friction of the rods and their'supports, is the raising of the oil in half of the wells at a time. Thus a motor which, connected directly with the well in the old manner, would scarcely suffice for a single Well may thus provide ample power to pump from four to six.

Another advantage gained by my invention is, that after a well is bored the engine and heavy parts of the machinery may be at once removed and used for another boring, as it is no longer required, as in the old process a great part of it is.

When the number of wells to be pumped is too great to admit of their being all connected with the same wheel B, another similar oscillating wheel, such as B, may be erected and connected with the wheel B by means of rods 0," a, so that its motion shall be similar.

It is obvious that when the wheel B is properly balanced it will not aifect the equilibrium of the wheel B.

Fig. 3 shows another method of attaching numerous wells to a single motor, and may be advantageously used where the number of wells in connection is not too great for two wheels.

Where strokes of different lengths are required for the wells connected with the same wheel the object is attained by lengthening or shortening the arm to which the reciprocating rods are attached, or by setting the rods at an angle more or less oblique to the arm, the maximum stroke being when it is at right angles.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The combination, with the reciprocating pump-rods of numerous oil-wells, of an oscillating horizontal wheel or wheels connected directly thereto, substantially in the manner and for the purpose described.

EDWARD D. YATES.
