DRILL-ROD CLAMP.

Specication of Letters Patent.

Patented Feb. 25, 1919.

Application led J une 24, 1918. Serial No. 241,625.

`To all whom t may concern Be it known that I, HERMAN Bunsnwnron, a citizen of the United States, residing at Kaukauna, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Drill-Rod Clamps, of which the following is a specification.

This invention relates to improvements in drill rod clamps and its object is to provide means for supporting pipes, rods, posts or the like. The device is adapted more particularly for application to pump rods to facilitate raising or lowering of the same into wells or drill holes. A further object is to provide a device of this type that when applied to the pipe or rod'will sustain itself in such engagement, that is readily adjustable longitudinally7 of such pipe or rod, that can be made to grip the same at one or two points as desired and that can be instantly released from such engagement. A further object is to provide a device of this type adapted to operate with the maximum etliciency, that is simple in construction, of few parts, and that is cheap to manufacture.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawing which forms a part of this specification and in which- Figure 1 is a view of Vmy improved drill rod clamp in side elevation illustrating its application.

Fig. 2 is a top plan view of Fig. 1.

Like reference characters denote corresponding parts in both views.

The device comprises a frame or body portion having one closed rounded end 1 and the diverging sides 2, 3, the side 2 terminating in the curved stationary j aw 4 and the side 3 at its free end having the outwardly bent extensiony 5, said extension being disposed substantially at rightl angles to the side proper and termina-ting in the guide-shoe 6 adapted to engage with the pipe or rod under operation. I provide a movable jaw 7 having the handle or finger-piece S and formed with the perforations 9 to receive the bolt 10 whereby it may be adjustably secured to the frame side 2 for coperation with the stationary jaw 4.

A bracket 11 is adjustably secured by the screw bolt 12 to the outer side of the frame side 3, said bracket being formed with the guide lips 13 adapted to embrace said frame side, said bracket having one portion bent parallel to the extension 5, said bent portion carrying the set screw 14 adapted for engagement with the work. VA brace 15 is secured to the. bracket 11 to give rigidity to the same. In operation the stationary jaw 4 and movable jaw 7 are applied to the pipe or rod 15a, the rod being rmly clamped between said members, likewise the shoe 6 is applied to the rod and the set screw 14 may be moved into frictional engagement with the rod. A firm purchase at two points is now had upon the rod and the operator may raise or lower the same by using the frame sides 2, 3 as a handle. The clamp may be rested upon the ground with the rod in the drill hole, if desired, without danger of the rod slipping or dropping to the bottom of the hole.y The clamp and rod may be readily disengaged by manual rotation of the screw 14 and by movement of the jaw 7 out of engagement with the rod.

What is claimed is l. In a drill rod clamp, a frame having one closed end and sides diverging from said end, one of said sides terminating in a stationary j aw, a movable jaw adjustably pivoted to said frame side for cooperation with said stationary jaw, the other of said frame sides having an outwardly bent extension, a guide shoe terminating said extension, a bracket adjustably secured to the last named frame side, and work-engaging means carried by said bracket.

2. In a drill rod clamp, a frame having one closed end and sides diverging from said end, one of said sides terminating in a stationary jaw disposed in the plane of said side, a movable jaw adjustably pivoted to said frame side for cooperation with said stationary jaw, the other of said frame sides my own I have hereto affixed my signature in hzlwng an outwardly belnt eztenson, a guide the presence of tWo subscribing Witnesses. s oe terminating saic sic e extension a y bracket adjustably secured to the last named HERMAN BURSEWEIDE' 5 :Emme side, and a`set Screw carried by said I/Vitnesses:

bracket. PETER WEYENBERG,

In testimony that I claim the foregoing as NICHOLAS DERCKS.
