CABLE GRIP; APPLICATION FILED JULY 3' l9l5.

g v MM HUGH r. ELLARD, or MISSOULA, MONTANA.

CABLE-GRIP.

Application filed July 8, 1915.

To all whom it may concern:

Be it known that I, HUGH F. ELLARD, of Missoula, in the county of Missoula and State of Montana, have invented certain new and useful Improvements in Cable-Grips; and I do hereby declare the following to 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.

The object of my invention is to produce a simple and highly eificient cable or rope grip for use in moving loads such as logs, etc, from place to place by a transmission rope or cable.

In the accompanying drawing, Figure 1 is a side elevation the full lines showing the position of the parts when closed, the dotted lines indicating their open position. Fig. 2 is a detail view of one of the gripping jaws. Fig. 3 is a detail of the link. Figs. 1 and 5 show a slight modification of the jaws.

Referring to the drawing, 1 designates the bar constituting the main frame of the device, and adapted to be made fast as at 2 to a load, while the jaws 3 at its other end are for attachment to the moving rope or cable by which the load is to be transported.

One of the essential features of my invention is to provide means for opening and closing the jaws which will insure the maxi- Q mum grlpplng actlon upon the cable, and at the same time permit 'of varying the grip according to the size of the cable. I also arrange the parts so that when locked they do not project outward unnecessarily, and hence are unlikely to catch in tree branches or other obstructions. I have shown the bar 1 formed near its forward end with a pair of laterally projecting ears or lugs 4, and a gripping jaw 5. The bar has a second pair of cars or lugs 6 shown at about its central portion, and below these the bar is channeled as at 7 to constitute a receptacle for the main operating lever when the device is locked.

The jaw S is carried on a lever 9 fulcrumed on the lugs 4 and the main operating lever 10 is fulcrumed 0n the lugs 6. Levers 9 and 10 are connected by the link 12. This link is of peculiar formation. It comprises a sleeve Specification of Letters Patent. Patented Feb. 2? 191'7.

Serial No. 38,831.

13 shown fulcrumed on the lever 9 and intercrumed on the short arm of the lever 10 and is received by the sleeve. This bar has spaced apart lateral portions to receive the short arm of the lever 10 and through these lateral portions extends a bolt 15 having a cotter-pin 16. By this means the bar may be removed from the lever and turned to project it inward -or outward relatively to the sleeve to enable the jaws to accommodate rarious sized cables and to vary the tension of the aws on the cable as the weight of the load may require. I

In order to insure the jaws meeting squarely, that is, to avoid any lateral play between them I have shown the meeting face of one of the jaws provided with alinement pins 17 to be received by corresponding recesses 18 in the meeting face of the opposite aw.

'It is sometimes desirable, in order to avoid pinching or biting the cable when the relative position of the load and the rope is variable, to have the jaws disposed at varying angles to the position of the gripping device.

To meet this requirement the'jaws may be pivotally mounted on their respective bar and lever, as shown in Figs. 4: and 5, where bolts 19 allow the machine proper to swing relatively to the jaws.

I claim as my invention:

1. In a cable grip, a bar having a jaw, a levercarrying a j aw and fulcrumed on said bar, a second lever fulcrumed on said bar, and means for adjustably connecting said levers.

2. In a cable grip, a bar having a jaw, a lever carrying a jaw and fulcrumed on said bar,a second lever'fulcrumed on said bar, a.

link connecting said levers, and means for adjusting said link toregulate the movement 7 of the jaw carrying lever.

3. In a cable grip, a bar lever carrying a jaw and fulcrumed on. said bar, a second lever fulcrumed on said bar, a link connecting said levers, and means for adjusting said link to regulate the movement of the jaw carrying lever, said link comprising a threaded sleeve fulcrumed to one of having a jaw, a
