Stuffing Box Sheave Assembly With Retention Pad
US Patent:
6105939, Aug 22, 2000
Filed:
Apr 3, 1998
Appl. No.:
9/054841
Inventors:
Russell L. Vance - West Jordan UT
Derek D. Carlson - Bountiful UT

Abstract:
A stuffing box sheave assembly includes a brace having a tubular collar positioned at one end and a pair of spaced apart forked arms outwardly projecting from the opposing end. A nylon wheel is rotatably mounted between the forked arms. The wheel has an annular grooved recessed around the circumference thereof. The groove is configured to receive a wireline. An arcuate shroud is positioned over a portion of the circumference of the wheel. A pair of spaced apart retention pads are mounted to the shroud. Each of the pads are configured to be received within the groove of the wheel so as to prevent accidental jumping of the wireline out of the groove. A pair of tubular posts project from opposing sides of the shroud and are selectively received within the channel of a tubular member upwardly projecting from each forked arm.
