WEDGE-G RIP.
SPECIFICATION forming part of Letters Patent No. 739,511, dated September 22, 1903.
Serial No. 148,917. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM E. SPENcEE, a citizen of the United States, residing at \Vexford, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wedge-Grips; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to certain new and useful improvements in a wedge or grip for holding polish-rods for oil or Artesian wells; and my object 'is to provide a means for securing a polish-rod to the usual form of walking-beam or the like. The device may also he used in connecting suction-rods of pumps to the source of power. A
Other objects and advantages will be hereinafter referred to in the specification and pointed out in the claims.
In the drawings, Figure l is a perspective View of my deviceas applied to use. Fig. 2 is a central vertical sectional view thereof. Fig. 3 is a central horizontal sectional view of the same. Fig. 4 is a similar view of a slightly-modified form, and Fig. 5 is a perspective view of the wedge proper.
Referring to the drawings, in which simi-,
tube 3,- to which it is securely attached, the
opposite end of said shaft being threaded and adapted to enter a threaded socket in one end of the body portion of the gripping memher 4.
ber 4, a slot 7 is cut transversely in said member, said slot terminating at one end in an orifice 8. -Adapted to be seated in the slot 7 is a wedge-shaped member 9, which terminates in a stud-section 10, adapted to enter the orifice 8 of the slot 7, said stud being threaded and provided with a bur 11 for a purpose hereinafter more clearly set forth.
When it is desired to clamp the rod 6 within the member 4, the bur 11 is turned out-.
wardly upon the stud 10 until the wedgeshaped member 9 passes out of the path of the bore 5, when the rod 6, is inserted into said bore and the bur 11 again turned onto the stud 10, which operation draws the member 9 inwardly, one edge thereof contacting the rod 6, and thus firmly clamping said ro within the member 4. I 1
In order to present a flat surface for the bur 11 to take against the face of the member 4, that part immediately adjacent to the orifice 8 is cut away, as shown more clearly in Figs. 3 and 4. Theedge of the member 9 designed to engage the rod 6 is provided with longitudinal teeth or corrugations 12, so that when the member 9 is drawn inwardly the teeth will take slightly into the material comprising. the rod 6, so that any longitudinal movement of the said rod is impossible.
While I have described my invention as applied to use in connection with oil and Artesian well appliances, I desire it to be understood that it maybe used in various ways and for divers purposes.
.In Fig. 4 of the drawings I have shown a slightly-modified formof bore. 5 in the gripping member in that said bore is octagonal instead 'of being round, as shown in the other views, in which case the rod 6 is held more firmly in position by being brought into contact with the uneven surfaces thus formed and prevented from turning therein. I have also shown the bore 5 as being in the center of the member 4; but it is clearly apparent that the same result may be attained by placing the bore 5 to one side of the center of said member and correspondingly changing the location of the slot 7, in which case the orifice 8 and'stud 10 will be centrally located with respect to the member 4, thus providing a bearing-surface for the bur 11 without cutting away anyportion of the face of the member 4.
While I have described the preferred construction and combination of parts deemed necessary in carrying out my invention, I desire to comprehend such substantial equiva lents and substitutes as may be considered as falling fairly within the scope of my invention.
What I claim as new, and desire to secure by Letters Patent, is
1. In a gripping device, the combination with a polishing-rod, or the like, of a member 4 having a bore throughout its length, a tube 3 secured to one end of said member, a slot transversely disposed in said member and adapted to intersect said bore, a wedgeshaped member adapted to enter said slot, means upon one edge of said wedge-shaped member adapted to take into said polishingrod and prevent lateral movement and additional means for moving said Wedge into engagement with said rod, substantially as set forth.
2. In a gripping device, the combination with a polishing-rod, or the like, of a member 4c having a bore throughout its length, said bore being octagonal in cross section, a shaft 3 secured to one end of said member, a slot transversely disposed in said member and adapted to intersect said bore, a Wedgeshaped member adapted to enter said slot, corrugations upon one edge of said Wedge adapted to take into said rod, and means for moving said wedge into engagement with said rod substantially as set forth.
In testimony whereof I affix my signature in presence of two Witnesses.
WILLIAM E. SPENCER.
