HIRAM B. HARDING, OF LOS ANGELES, CALIFORNIA.
TUG SHEAVE-CLUTCH.
SPECIFICATION forming part of Letters Patent No. 707,321, dated August 19, 1902.
Application filed October 19, 1901. Serial No. 79,230. (No model.)
To all whom it may concern:
Be it known that I, HIRAM B. HARDING, 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 Tug Sheave-Olutch, of which the following is a specification.
This invention relates generally to drill-rig appliances,and more particularly to a sheaveclutch for a tug-rope pulley, the objects of the invention being to secure perfect control of the tools while they are being raised'and lowered, to save the time of placing the tugrope on the bull-wheel when it is desired to pullithe tools, and also to save the time of removing the said rope when the bull-wheel is not in use.
Another object of the invention is to provide a device which will prevent the wear upon the tug-rope which occurs in the present form of rig by the rope remaining upon the tug-sheave while the rig is in action.
With these objects in view the invention consists in the novel features of construction and combination hereinafter fully described, and pointedout in the claims In the drawings formingapart of this speci fication, Figure 1 is an enlarged view showing in elevation a portion of the band-wheel and tug-rope sheave. Fig. 2 is a sectional view of the band-wheel, tug-sheave, and the clutch mechanism, the shaft and the operating-lever being shown in plan. Fig. 3 is a perspectiveview showing a portion of the tug-sheave. Fig. 4 is a view showing aportion of the bandwheel and clutch-section. Fig. 5 is a detail view illustrating the manner of connecting the sheave-spokes to the rim, the spokes being shown in dotted lines; and Fig. 6 is a section taken on the line 8 8 of Fig. 4c.
In carrying out my invention I make no change whatever in the general construction of the rig; but to the inner face of the bandwheel A, I securely fasten a circular toothed rim B, said rim being securely bolted to a spacing-rig 0, attached to the face of the band-wheel, and in practice I prefer to employ a reinforcing-plate 0 upon the opposite face of the band-wheel, and I also prefer to employ the central reinforcing and bearing plates 0 The band-wheel is mounted upon the shaft D, and loosely mounted upon this projecting ears or lugs E to which the outer ends of the spokes are secured, parallel flanges E connecting the said ears or lugs E with the rim E, thereby providing sockets into which the outer ends of the spokes fit, and by referring to Fig. 4 it will be noted that the outer side of the rim E is beveled or cut away, as shown at E and that the outer ends of the spokesare shouldered, as
shown at E in order to embrace the inner edge of the rim snugly.
The hub E is formed with a broad collar E to which the inner ends of the spokes are attached, a circular ring or plate E 9 being arranged upon the opposite side and through which the bolts are passed, thereby securely clamping the spokes between the collar E and circular plate or ring E The outer end of the hub is formed with a circumferential groove, in which fits the bifurcated end I of the shifting-leverl, "saidlever being fulcrumed upon the upper endof a post K, car rying a pin K, a strap Ed -being secured to the side of the lever for me ur ese of embracing the said pin, thereby securely pivoting the lever upon the end of the post. The lover I extends to a point where it is within easy reach of the operator, and by shifting the lever the tug-sheave can be thrown toward the band-wheel, and the moment the clutch-teeth E engage the toothed rim B the tug-sheave will virtually become a part of the band-wheel and will move in unison therewith, and consequently operate the tug-rope, which in turn will operate the bull-wheel. When it is-desired to check the operation of the bull-wheel, the rope or lever is reversed, drawing the tug-sheave away from the bandwheel, and it will thus quickly come to a state of rest, while the band-wheel is permitted to rotate without operating the rug-rope or the bull-wheel.
It will thus be seen that I provide a very simple but highly efficient device which can cessity of removing and replacing the bullrope, and it will also be noted that I also avoid all unnecessary wear upon the tug-rope.
The tug-sheave although extremely light in construction is also built up in a manner insuring its durability.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is,
1. Atug-sheave comprising in combination a rim having a circumferential groove and provided with clutch teeth at regular intervals, said rim having sockets, the spokes having their outer ends secured in said sockets thehub to which the inner ends of said spokes are attached, said hub having a circumferential groove, a shifting-lever adapted to fit said groove and the band-wheel provided with clutch-teeth, substantially as described.
2. Atug-sheave comprising in combination a rim having a circumferential groove and provided with clutch-teeth upon the inner face of said rim at regular intervals, the inwardly-projecting ears or lugs integral with the rim and in alinement with the clutchteeth, the parallel flanges connecting the rim and ears or lugs thereby providing sockets, the spokes shouldered at theirouter ends and fitting into the said sockets and embracing the edge of the rim, the hub formed with a collar to which the innerends of the spokes are secured, and the band-wheel provided with clutch-teeth, substantially as shown and described.
