TENSIONING- A 'ND PULLING DEVICE.

Appncaticn inea aamiary 2e, 192i.

To all whom it may concern Be it known that 1,. JEPTHA M. NEWTON, a

4citizen ot the United States,'l residing at Dothan, in the county oli' Houston and State of Alabama, have invented certain new and useful Improvements in Tension'ing and Pulling Devices; and I do hereby declare the following to Vbe a full, clear, and exact description of the invention, such as willeir able others skilled inthe art to which it appertains to make and use the same.

This invention relates to an improved device-1used for pulling stalled automobiles or other vehicles out ofa mud hole, lor stretching fence wires orifences of the woven wire type, orV ior any other similar use.

One object of the invention is to provide a puller or stretcher of the type specified which is so constructed .that the'pulling or stretching may be done with a minimum amount ot labor and without. danger ot vthe grapple slipping `and releasing they fence wires or article being pulled.

Another object of the invention `is to so construct this device thatthe amount of pullv or stretch accomplished at one setting up oi the device may bel controlled.

Another object of the invention is to so construct this device that `it will be very simple in operation andveryeasy to set up.

Another object of the invention is toV so construct this device that it maybe easily and cheaply produced and to further so con struct it .that it may be strong yand durable and not liable to break. i

This invention is illustratedin the accompanying vdrawings wherein :i

VFigure 1 is a side elevation of .the improved device. f

Figs 2 is a 'longitudinalalong the line 2-2 of Fig. 1.

Fig. 3 is an enlargedview showing one of the ladder sections inside elevation.

This device is provided with an actuating lever 10 which will be engaged by a pivot bar or hook 11 extending* from and conlsection taken Specification of Letters Patent'f Patented Dee. 113, 1921.

nected with an anchoring post 12.y f The pivot" rod or bar is detachably secured to the lever 10 thus permitting the lever to be released from this bar when it is desired'todetach the device until again used. Openings 13 lare formed in this lever above and below the openings through which'the hooked yend of the pivot bar passes thus permitting the hooks 14- to be pivotally connected with the lever and' said. hooks areheaded tov prevent them fromvbeing detached from said lever.

These hooks `will each bev provided with a head 15 having an inclined cam edge 16 and a straight cut rear edge '17 so that the hooks may have the proper action as will-be hereinaiter brought out. rk ladder element isy provided for engagement by the hooks 14 vand will he formed'of plurality ofsections 187.7each of which will he.` .provided with upper and lowerrows of openings 19 and 20,

the openings'ot the upper row 19 being' poi sitioned in staggered relationto the openings of the lower row.: 20. Grooves 21 are formed in the sections v18 longitudinally thereof and .extend from one opening to another in each line of openings. It should be noted that grooves are so vcut that they will start from the lower portion of one of the Vopenings and Aterminate at theupper portion oit the adjoining or following opening vor` in other words that these grooves decrease in depth from one opening to another. Since the grooves decrease in depth from one openingtothe other the straight cut edge 17 of the head 15 may Obtain a rni grip upon the ladder sections when the head is vresting in one of openings `but may-move easily out of the openings to a second open-l ing through engagement of the inclined or cam 'edge`16 with the' sloping grooves. By

having the openings positioned, in staggered.'`

relation the lever may be swung .upon its pivot and one of the hooks 14. moved to exert a strainupon the ladder structure `or element while the second hook fis moving through the groove :trom one openingV to another.4 These sections 18l which` constitute the ladder are connectedby links 22" which are formed of heavy rod'metal aiidhaving larmsA passing 4through*openings' 28 formed inthe ladder sections.` It will thus beseen that any number of ladder sections may be provided according to the amountv of pull it is thought it will be necessary. This ladder element has a chain element connected with it, the chain element being formed of a plu rality of links 24C each or' which is Vprovided with large ends 25 having openings 26 formed therein thus permitting the links tol be connected by lil-shaped fasteners 27. @ne

, of these fasteners 27 will be used for connecting the inner links of the chain elements with the ladder element. Y As' many links may be used as will berliound desirable according to the length oit, the chain required. This chain element will have a suitable engaging element connected with its `obvious that if desired Vor convenient a tree could be made use of and a chain or ieiiible cable passed about the tree and connectedV with the .pivot bar. The chain element will beconnected with the automobile orother object upon which `it is desired to exert a pulling force and the hooks 14 will then be Y positioned to engage the openings of one ot been extracted from the mud or y ystretchedas tight as desired the device may `the links or sections forming the ladder.V The lever may now be rocked upon the pivot bar and in doing so the hooks will move `from` one opening toanotherthrough the groovesofthe ladder sections.` It will thus be seen that the ladder element and chain element may be drawn tight and held tight by one hook vwhile the second is moving from one opening"k to another to obtain a new grip `-upon the :ladder element. It is therefore only necessary to oscillate thek lever in order to exert a pulling force to withdraw an automobile from a mud'hole, stretch a fence wire, or woven Wire fencing or toV exertV a pulling action upon an obj ect if it is-desired to pull or stretch.v After the automobileor other object has been moved as far as per- -mittedloy the vhooks reaching the end ofthe Y ladder section the anchor post may be removed and again driven intothe ground at a.

point removed from the automobile and the operation repeated. Afterthe automobile has the fence bevtaken apart and packed away in a small space;

ThereV has therefore been provided a device of the character described Whichis very eicient in operation and very easy to operate. V 1

' t wat is claimed is l. A device of the character described com- `prising'ananchoring element, an actuating .f

Licda/1 lever pivotally connected with the anchoring element, a ladder element having'longitudinally extending rows of openings with the openings of one row positioned in stepped relation to the openings of the second ro-w,hooks pivotally connected 'With the actuating lever' upon'opposite sidesof the pivot point thereof and having heads Vfor fitting into the openings of the ladder elements, the ladder elements provided with longitudinally extending grooves connecting the openings and decreasing the depth from one opening to another,the free ends oi the hooks being cut at an incline to provide camedges causing the hooksto ride easily :tromone opening to another, and a f chain element connected with the ladder element.

2. A device ofthe character described including a pivotally mounted actuating lever, hooks loosely connected with the actuating lever upon opposite sides of the pivot point thereof, and article engaging means including a ladder structure lprovided with longitudinally Iextending rows oi openings posi-A tioned in st-aggeredrelation, the ladder struc- Yture being Vprovided with grooves leading from one-opening to another and decreasing in depthV from oneopening to another.
