, J. MARTINSON CABLE CLAMP Filed June 18 1923 Patented Feb. 5, 1924.
UNITED STATES JOHN- MARTINSON, or WRENSHALL, MINNESOTA.
CABLE CLAMP.
Application filed June 18, 1923. Serial No. 645,939.
To all whom 2'2 may concern:
Be it known that 1, JOHN MARTINSON, a citizen of the United States, residing at Wrenshall, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Cable Clamps, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to a cable take up and has special reference to a device of this kind in connection with the anchoring or pulling cable of a stump puller.
The principal object of the invention is to produce as simple a device of this character as possible, and one having the maximum strength with the least weight.
Another object is to provide a take up of this type which may be quickly and easily slacked off without diminishing the pull on the line to which it isapplied.
Still another object is to provide a device of this. kind which is most easily accessible respecting the application of the cable thereto.
Other objects and advantages of the invention will appear in the further description thereof.
Referring now to the accompanying drawing, forming part of this application, and in which like reference characters indicate like parts:
Figure 1 is a perspective view of one of the improved take ups as applied to a cable;
Figure 2 is a front edge view of the relative position of the cable gripping jaws; and
Figure 8 is an enlarged perspective View of the release lever.
The cable gripping portion of the take up comprises two pivotally united members 1 and 2, their pivotal connection existing at 3, they resting one against the other. Each of these members is provided with a widened central portion and flat upon their abutting faces so as to lie snugly together, the widened portion 4 of the member 2 having a reduced lug extension 5 thereupon for the reception of the operating chain 6, the opposite end of which is connected to the circumferential face of the hub 7 of the tension lever 8 pivoted at 9 upon the head 10 of the hollow spider 11 attached to the end of the holding cable 20.
Out of the shoulders of the spider 11 extends two short resilient branch cables 12 forming a bridle to the extreme ends of the gripping portion of the implement as above described, the ends of the bridle cables being permanently united by leading them in, as is common, or fastened otherwise, if desired.
The edge face 13 of the widened portion 4 of the member 2 forms one cable gripping jaw, while opposite to it and spaced therefrom is the jaw 14 pivotally mounted as at 15 upon the member 1.
Now it is evident that if the cable 16, which is represented as being held by the take up, is placed intermediate of the jaws 13 and 1 1 and stress put thereupon, it will tend to compress the jaws against the opposite sides of the cable and hold same, as the member 2 operates in a cam like motion upon its pivotal point 3. However, were it not for some other force it is also evident that the jaws might not engage the cable under all circumstances. To overcome this dif'iculty it will be observed that the axial lines of the sockets 17 and 18 upon the ends of the members 1 and 2 respectively are substantially parallel with that of the cable being pulled so that there is a decided tendency to spring the pivotal point of the two members 1 and 2 outwardly in the bridle, the cables trying to assume their normally straight position so that in order to place the cable 16 intermediate of the jaws 13 and 14: it becomes necessary to force their united portions towards the spider 11 which tends to open same, and when released they will naturally pinch the cable 16 therebetween.
When it becomes desirable to release the cable thus held, I provide the chain connection 6 to the hub crank of the lever 8 on the head of the spider, so that a turning of the lever 8 in either direction will by winding the chain upon the hub thereof tend to forcefully draw the spider and the gripping jaws together, which act will instantly release the hold of the take up on the cable. I prefer to place the lever 8 on the backside of the spider as shown so as to not be in the way of the loose end of the line 16 as it lies over the face of the spider.
From the foregoing it is evident that I have devised an exceedingly simple and efficient cable take up which may be used in connection with cables for varied purposes.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is:
1. A cable take up comprising in combination a holding cable, a spider permanently attached to the end of said cable havingresilient bridle arms extending therefrom, and two pivotally united cable gripping elements suspended upon the free termini of the bridle cables.
2. A cable take up comprising in combination a holding cable, a spider permanently attached to the end of said cable having resilient bridle arms extending therefrom, two pivotally united cable gripping elements suspended upon the free termini of the bridle cables, and means for manually retracting the position of the gripping elements to- 15 wards the spider for releasing same.
3. A cable take up comprising in combination a holding cable, a spider permanently attached to the end of said cable having resilient bridle arms extending therefrom, two pivotally united cable gripping elements suspended upon the free termini of the bridle cables, a lever pivotally mounted upon the head of the spider, a chain intermediate of the lever and one of the jaws and attached to same for releasing the grip.
In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
JOHN MARTINSON.
