Patented Dec. 4, 1923.
UNITED STATES SUMNER B. SARGENT, OF LOS ANGELES, CALIFORNIA.
' GRIP ron roLIsn RODS AND THE LIKE.
Application filed October 3, 1922. I Serial No. 592,081.
T 0 all 10 hom it may concern:
Be it known that I, SUMNER B. SARGENT, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Gripfor Polish Rods and the like, of which the following is a specification.
This invention relates to devices of the character employed for supporting a sucker line. 1
An object of the invention is to provide a device of this character that can be clamped very tightly on the polish rod or other member which is to be gripped.
Another object is to provide a grip in which relatively great leverage can be exerted upon the jaws.
A further object is to provide a grip of a construction that is operable to temporarily distort the polish rod transversely of its axis so as to more effectually prevent slippage thereof through the grip.
The accompanying drawings illustrate the invention:
Figure 1 is a side elevation of a grip constructed in accordance with the provisions of this invention, a polish rod being shown clamped in the grip.
Fig. 2 is a sectional elevation on the line indicated by 22, Figure 1.
Fig. 3 is an inverted plan view of Fig. 1.
There is provided a body 1 having a longitudinally extending channel or groove 5. The channel 5 provides alternately arranged concave faces 6 and straight faces 7, the same being shown to an exaggerated degree in Figure 2. Thus the channel 5 has alternating portions of larger and smaller diameter.
At its lower end the body 4 forms a pair of shoulders 8 at right angles to the longitudinal axis of said body, said shoulders'being defined by the upper face of laterally extending lugs 9 which are spaced to form an extension 10 of the channel 5 so that the channel 5 may be readily brought into engagement with the polish rod or like member, indicated at 11, that is to be clamped to the body 4.
A plurality of movable jaws 12 extend transversely of the channel 5 and are movably connected at one end with the body 1, in this instance the connection being a pivot 13 which passes transversely through the jaws and through spaced ears 14 of the body 4 interposed between each two adjacent jaws 12. The jaws 12 are channeled at 20 and are pivoted to the body inv alinement with the concavities 6, and the inner faces of the jaws are convex, as indicated at 15. Thus the channels 20 of the jaws 12 and the portions of the body channel registering with the jaws are correspondinglycurved longitudinally.
, lThebody 4 is provided transverselyof its longitudinal axiswith a series of bolt holes 16 in which are inserted bolts 17. The bolts 17 are adapted to project through bolt holes 18 which register with the bolt holes 16 when the jaws are closed upon the body 4, as indicated in the drawings. The nuts 19 of the bolts are adapted to be screwed against the clamps to independently force said clamps toward the body 4: and thus grip the polish rod 11 firmly between the body 1 and the jaws. Because of the particular concave faces of the body {1 and convex faces of the jaws 12, when the jaws are forced against the polish rod, by tightening the bolts, those portions of the polish rod alined with the jaws are sprung 0r deflected into the concavities 6 as indicated to an exaggerated degree in Figure 2, thus making it impossible for the polish rod to pull out of the grip.
It is important that the polish rod be very securely clamped since a reciprocating motion is imparted to the clamp to efi'ect the pumping operation and there is thus great danger of the polish rod becoming detached from the grip. The great weight of the sucker line suspended from the grip, and the weight of the pump plunger together with that of the column of liquid being pumped makes it difficult to prevent slippage between the polish rod and grips of prior construction, and it will be clear from the foregoing that this improved grip will accomplish this very efi'ectually by a comparatively simple construction.
When the lowermost jaw 12 is closed it rests on the shoulders 8 and thus the lugs 9 aid in supporting said jaw against the downward pull produced on it by the polish rod.
I claim:
1. In a grip for polish rods and the like, the combination of a body having a longitudinally extending channel, a plurality of channeled jaws movably connected at one end thereof with the body and extending transversely of the body channel, and means to independently'force the other end of each jaw toward the body.
channeled jaws movably connected at one;
end thereof withithe body and extending v transversely of the body oha'nnehthe chan nels' of the jaws and the portionsof the body channel registering with the jaws being correspondingly curved longitudinally, and, means to independently force the other end of each jaw toward the body.
' 3'. In a grip for polish rods and the like, the combination of a body having a longitudinally extending channel and having spaced ears, a plurality of spaced channeled jaws, a pivot passing transversely through e 1' we an ea d ean n p ently -foroe each of the jaws toward the body.
4. Ina grip for polish rods and the like, the combination of a body having a longitu dinally extending channel and bolt holes extendingtransvers'ely of the longitudinal axis of the body, a plurality of channeled jaws having bolt holes near one end, bolts extending through the bolt holes of the body and jaws, and means movably connecting the other end of each of the jaws to the body.
5. In a grip for polish rods and the like, the combination of a body having a channel along its median line and having spaced ears along one margin, spaced channeled jaws hingedat one end .to the ears, and means to force the other end of each jaw toward the body.
