FOOT FOR SAN D-LEVERS.

SPECIFICATION forming part of Letters Patent No. 401,611, dated April 16, 1889.

Application filed May 7, 1888. Serial No. 273,071- (No model.)

To all 101 2 0772 in may concern:

Be it known that I, CHARLES VEZIE, a citizen of the United States, and a resident of Deuison, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in Feet or Castings for Sand-Levers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my improved casting or foot for sand-levers, show ing the same secured in operative position to the lower end of a sand-lever and in proximity to several of the parts of the mechanism employed in well-boring. Fig. 2 is a perspective view of the casting removed from the lever, and Fig. 3 is a view of several modifications of the shoe or casting removed from the sand-lever.

Similar letters of reference denote corresponding parts in the several figures.

My invention has relation to that class of devices known as castings or feet for the lower ends of sand-levers, and which are adapted to rock in suitable bearings secured to the main sill of a derrick employed in the boring of oil or other wells, whereby mechanism, substantially as hereinafter described, is thrown in and out of gear when desired.

To this end my invention consists in the improved construction and combination of such a device, as will be more clearly set forth in the following description.

In the accompanying drawings, the letter A denotes the main sill of a derrick employed in well-boring, and which is formed with a bearing, 13, having an aperture, 5, formed in its center.

C denotes the sand-lever, of the usual construction, to the lower end of which is secured my improved foot or casting D, consisting of the solid cylindrical body E and the upwardly-proj ecting wings F, formed at right angles to each other, thereby producing a two-sided socket. The intermediate portion of this cylindrical body E, which forms a base for the two-sided socket, is preferably cast square, as shown at G, which square part forms a solid bearing for the lower end of the sand-lever. This casting is secured to the lower end of the lever by means of bolts H, inserted through the holes I in the wings. The foot or casting is now journaled in the bearing B of the main sill of the derrick, so as to rock back and forth.

J indicates the drive-wheel journaled in suitable bearings, and from which motion is imparted to the drill-reel K by means of the belt L. This drill-reel acts directly upon the drill mechanism, a further description of which is deemed not necessary. Journaled with one end of its shaft Min a rocking bearing, N, and with the other end of its shaft in a bearing, 0, in the side of the sand-lever, is a sand-reel, P, which,by the rocking of the said sand-lever, may be brought into and thrown out of gear with the drive-wheel by means of the frictional gearing Q, one wheel of which is upon the shaft of the drive-wheel, while the other wheel is upon the shaft of the sand-reel.

A chain or rope, R, is secured to the sandreel and passes 'over a pulley near the mouth of the well, and to that end is secured to the sand-pump. After the boring has gone on for a considerable length of time the drill is removed and the sand-pump is dropped into the well and becomes filled with the borings. Now the sand-lever is rocked forward by the workman pulling upon the rope R, which throws the friction-wheels into contact or gear and causes the sand-reel to be revolved, which, in winding the rope or chain around it, raises the sand-pump.

I would have it understood that I do not claim the mechanism herein set forth as part of my invention, and have only shown those parts as was thought necessary to illustrate the object of my invention, the well, derrick, and sand-pump not being shown, as it is thought the device will be readily understood when taken in connection with those parts now illustrated.

If desired, the cylindrical body may be cast with only one wing, or, on the other hand, with three or four, as shown in Fig. 3. In

either case the operation of the invention will be the same, as the cylindrical body portion is really the essential part of the invention.

It will be seen that my invention is employed instead of a knuckle post, which is objectionable for many reasons, and particularly for the reason that the parts are apt to become Worn and to work loosely or to become clogged in its joints with dust, 850., which will accumulate and adhere to the joints, which are usually lubricated, thus preventing a free and easy movement of the sandlever.

This invention is not necessarily limited to Well-boring mechanism, as it can be employed in any class of machinery wherein a rocking lever is employed with the same result as herein set forth.

From the foregoing description, taken in connection with the accompanying drawings,

the operation and advantages of my invention will be readily understood without requiring an extended explanation. It Will be seen that it is simple in construction, formed of but a few parts, and that it is exceedingly useful for the purpose for which it is designed.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- In a foot or casting for sand-levers, the combination of the semi-cylindrical bearing having an aperture formed in its center, a cylindrical body working in the said bearing and having a square intermediate portion adapted to fit in the said aperture, upward-extending- Wings made integral with the body and forming a socket, and a lever fitting in the said socket, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

CHARLES VEZIE.
