1 Claim.
This invention relates to clamps especially adapted for use on pumping equipment of oil wells and the like and has for the primary object the provision of a device of this character which may be easily and quickly adapted to a rod or like device of pump equipment and which will increase its gripping action on said rod as the load increases .and is provided with a yoke having a quick releasable part so that the application of the device to a pump jack or similar device will be greatly facilitated.
With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation illustrating a clamp constructed in accordance with my invention.
Figure 2 is a sectional view taken on the line 2-2 of Figure 1.
Figure 3 is a perspective view illustrating a split sleeve and showing a wedge forming an integral part thereof.
Figure 4 is a side elevation illustrating the split sleeve.
Figure 5 is a transverse sectional View taken o n the line 5--5 of Figure l.
Figure 6 is a transverse sectional view taken on the line 6-6 of Figure 1.
Referring in detail to the drawing, the numeral I indicates a body having formed therein a bore 2 opening outwardly through opposite ends of the body and also has one end beveled to form a seat 3. The body I has formed in one side thereof a slot 4 which communicates with the bore. The bore and slot taper towards one 4,0 end of the body. A split sleeve 5 tapers towards one end and is adapted to t in the bore 2. 'I'he split sleeve 5 before entering the bore 2 is adapted to a rod 6, as shown in Figure 3. The diameter of the rod is less than the diameter of the bore 2 so that the body can be readily adapted to the rod and then moved endwise thereof to bring the split sleeve 5 into seating engagement with the bo-re 2. A wedge-shaped rib 'l is formed on the split sleeve to enter the slot 4 as the split 5 sleeve 5 enters the bore 2. The reduced end of the split sleeve has formed therein an annular groove 8 to receive a split ring El which projects out of the groove to abut one end of the body I to prevent the body I from moving end- 10 wise of the sleeve in one direction. The split ring can be easily removed from the groove 8 when desiring to remove the split sleeve from the bore of the body I. The rod 6 forms a part of a pump equipment and the body has formed there- 15 on a yoke IU which may be adapted or connected with a pump jack or similar device and includes a removable section I I in the form of a link having both ends bifurcated and provided with aligned apertures to receive removable pins 20 E2. When one of the pins I2 is removed the link II may be swung on the other pin .as a pivot. By having the link I I removable or pivotal when desired will permit easy application of the yoke to a pump jack. 25
As the load increases on the clamp or rod greater wedging action will be established between the sleeve and the bore 2 and said sleeve being split will be caused to contract and create a tighter grip upon the rod 6. 30
What is claimed is:
A clamp comprising a body including means for connecting the same to pump equipment and having a tapered bore, a split sleeve to receive a rod and tapering towards one end and positioned 35 in the tapered bore to have a wedging action therewith and thereby bring about contraction of said sleeve on the rod, said sleeve having a groove in one end, a split ring mounted in said groove to engage with one end of the body, said body having a wedge-shaped slot communicating with the bore, and an elongated wedge-shaped rib formed on said sleeve and fitting in the slot.
