I Application filed May 27, 1897. Serial No. 638,356- (No model.)

To aZZ whom it may concern.- tion and a sectional view of a modified form Be it known that I, JOSEPH J. KWIS, of of pin used in connection with the drive- Findlay,in the county of Hancock and State wheel. Fig. 11 is aside elevation of the pin of Ohio, have invented a new and Improved usually employed in connection with said 55 Power Device for Pumping WVells and for drive-wheel. Fig. 12 is a side elevation of a Similar Purposes, of which the following is a further modification of the pin, and Fig. 13 full, clear, and exact description. is a section on the line 13 13 of Fig. 12.

The object of the invention is to provide a A represents a beam which constitutes a power device especially adaptable for pumpbed for an engine B, the type shown being 60 1o ing'oil-wells, but which may be employed for the ordinary oil-field engine. The poweranalogous purposes, the construction of said shaft of the engine is shown as provided power device being such that a practically atone of its ends with a. pinion 11, and this direct connection can be made between the pinion meshes with the teeth of a powerengine or other motor used and the mechantransmitting wheel 12, shaft 13 of which is 65 I 5 ism employed for operating the surface-rods journaled in suitable bearings 14, one of in oil-pumping machinery, the motion being whichis shown on the beam or foundation A' so communicated through the said drivingand the other upon a suitable sill A", near wheel as to prevent any twisting strain whatthe main foundation A.

In

Fig. 5 I have illustrated a pin 22 as projecting above and below the rim of the drivewheel, so that one surface rod may be pivoted on the pin at the channel 18 in the wheel, another above the rim, and a third below the rim. In Fig. 4 the rim of the wheel is enlarged and is provided with teeth 24, intermediate of the top and bottom teeth, and in this construction of the rim of the wheel two annular recesses 25 are formed. It is evident that under this latter construction a1 larger number of surface rods may be con I nected with each pin than under the construction illustrated in Fig. 5. The pitman 15, connected with the power-transmitting wheel 2, is likewise connected by means of the ball wrist-pin 16 with a horizontal extension 21 from the rim of said drive-wheel, as shown particularly in Figs. 1, 2, and 3. The drivewheel, through the action of the power-transmitting wheel, is given alternately a forward and a backward movement. The pins are connected to the drive-wheel through the medium of bolts or clips 23, which are shown as U-shaped, but may be otherwise shaped, as desired. These bolts or clips after passing around the pin are carried through the rim of the wheel.

In Figs. 6 and 7 I have shown brackets which may be utilized to provide for surface rods being attached to the drive-wheel at points beyond the rim proper. The bracket shown in Figs. (5 and 7 consists of a top and bottom plate 26, connected by two pins or posts 27, said plates being attached to a curved body 28, extending above and below the plates and provided with teeth 29, which are of such formation that they may enter the spaces between the teeth 011 the outer surface of the rim of said drive-wheel. I11 Figs. 8 and 9 I have shown a modified form of the bracket illustrated in Figs. (3 and '7. This modification of the bracket consists of a curved body 30, and from the concaved surface of the body teeth 32 are projected, which may enter the spaces between the teeth on the rim of the drive-wheel, and upon the outer or conveXed face of the body upper and lower horizontal plates 31 are formed, having recesses therein forming teeth, and the teeth formed in the plates 31 correspond to the teeth which are formed on the rim of the drive-wheel and reeeive between them pins similar to the pins 22, heretofore described, and upon which the surface rods are pivoted.

In Fig. 10 I have illustrated a modified form of the pin. This pin is provided with projections 33, so shaped that they will enter and fit into the recesses or spaces between the teeth on the rim of the drive-wheel or the teeth upon a bracket extension.

It will be understood that instead of the pinion 11, driy'en by the engine 13, meshing directly with the power-transmitting wheel 12 the motion may be communicated from the drive-shaft 10 of the engine to the shaft upon which the power-transmitting wheel 12 is placed or to the wheel direct in any other suitable manner, and that any desired motor may be employed.

It will be understood that bolts similar to the bolts 22 are utilized for securing the brackets to the drive-wheel and the pivot-pins in the brackets, and also that the recesses 20 on the inner face of the rim may be utilized for securing a bracket or any extension from the drive-wheel to said wheel. In Fig. 2 the extension from the drive-wheel to which the pitman 15 is attached is illustrated as connected in such manner.

I do not confine myself to either form of the driving-wheel 0 shown. The straps used for attaching the surface rods to the pins 22 may be of any desired length, and any necessary number of bolts may be employed for securing the straps. Each strap Si is provided with a half-box 35, having an opening to receive the bolt, thus permitting any lost motion caused by wear to be taken up. \Vhen the surface rods are of wood, they abut against the boxes 35; but whenever any other material than wood is used a block of wood or any other suitable material may be bolted in between the straps to fit against a box In Figs. 12 and 13 I have shown another modified form of a pin 22, which is turned from round bar iron or steel and is of enlarged diameter at each side of the center or where the pin does not connect with the surface rods, as shown at 36. Those portions of the enlargements 36 adapted to fit into the drivewheel are planed olf upon two sides, giving these portions of the pin an angular formation, as shown at 37 in Fig. 13. Grooves 38 are produced near the plain surfaces 37 to receive the U-bolts 23.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a power device for pumping wells and for similar purposes, the combination, with a drive-wheel having a toothed rim, brackets attached to said rims and pivot-pins adapted to receive surface rods or like devices, secured in the spaces between the teeth on the rim of said wheel and in the said brackets, for the purpose set forth.

2.. Ina power device for pumps, the combination of a drive-wheel having a toothed periphery, a bracket having teeth adapted to mesh with the teeth of the drive-wheel, a pin held by the bracket, and a surface rod having pivotal connection with the pin.
