'PUMP-RODIGRIP.

SPECIFICATION forming part of Letters Patent No. 673,679, dated May 7, 1901.

Application filed January 28, 1901. Serial No. 45,046. (No model.)

T at whom it may concern:

Be it known that we, JAMES ELMER FOSTER and CHARLES FLETCHER RIoHEY, citizens of the United States, and residents of Franklin, in the county of Venango and State of Pennsylvania, have invented a new and Improved Pump-Rod Grip, of which the following is a full, clear, and exact description.

This invention relates to improvements in devices for gripping pump-rods or other rods or pipes; and the object is to provide a device of this character of simple construction and so arranged that it may be easily attached to a rod or pipe and operated without danger of bending the rodor pipe.

We will describe a pump-rod grip embodying our invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a partof this specification,

in which similar characters of reference indicate corresponding parts in all the figures. Figure 1 is a side view, partly in section,of a grip embodying our invention. Fig. 2 is a top view thereof. Fig. 3 is a plan view, partly in section, of the grip-frame; and Fig. 4 is a side view of one of the gripping-jaws.

The frame of the gripping device consists of two side pieces 1 and 2, from one of which a pin 3 extends through an opening in the other side piece and is held by means of a cross-pin 4 through said pin 3 and engaging with the outer surface of the side piece. Mounted to swing on the pin 3 between the side pieces is a clamping-jaw 5, having a camshaped inner end to engage with a rod or pipe and having an outwardly-extended stem 6, provided with an eye in which is engaged a section of a chain 7, the upper end of said chain-section being connected toa ring 8, with which a tackle is designed to be engaged. Coacting with the .jaw 5 is a removable jaw 9, having a cam-shaped inner end and provided with a stem 10, through the eye of which a chain-section 11 extends to the ring 8. The removable jaw 9 is mounted to swing on lugs 12 and 13, extended inward from the side pieces 1 and 2. These lugs are designed to engage in channels 14, formed in the opposite sides of the jaw 9 and opening downward and outward. The outer edges of these channels are provided with inwardly-extended flanges 15 to engage against the inner sides of the heads 16, formed on the lugs. This, while permitting the jaw to swing freely onthe lugs, will prevent the side pieces of the frame from spreading outward relatively to the jaw.

This device is intended mainly to make connections between tackle-boxes and oilwell rod lines. When there is more than one oil-well on a lease, it is necessary to stretch iron rods from the well to the pumping power, which is located at some central point on the lease. The lines are given a backward-andforward motion, which works the rods up and down in the well, and the rods sometimes break, allowing the rods or lines to sag down between the carriers, which .are about thirty feet apart, and in order to repair a rod it is necessary to pull the two ends together and hold them until repaired. This operation not only takes up all the slack of the iron, but must lift the rods in the well, which cannot be done with a rod or chain hitch on the rod,

lugs 12 and 13, and then the framemembers passed along the opposite sides of the pipeand the jaw9 replaced.

Having thus described our invention, we

claim as new and desire to secure by Letters.

Patent 1. A rod or pipe gripping device, comprisinga frame having side members, a grippingjaw pivoted between said side members, headed lugs extended inward from said side members, the jaw having channels in its opposite sides to receive said lugs, and flanges extended from the sides of the channels for engaging the heads of the lugs, substantially as specified.

2. A gripping device, comprisinga frame having opposite side members, a jaw pivoted between said side members, lugs extended inward from said side members near one end, the ends of said lugs being headed, a jaw having outwardly-opening channels in its 0p posite sides for receiving said lugs, and flanges extended inward from said channels for engaging with the heads of the lugs, substantially as specified.

3. A gripping device, comprising a frame having opposite side members, a jaw pivoted between said side members and having an outwardly-extended stem, headed lugs extended inward from said side members, a jaw having channels in its opposite sides to receive said lugs, and flanges on the walls of said channels for engaging with the heads of 1
