IOST OR STAKE FULLER.

Application filed November 3, 1927. Serial No. 230,788.

This invention relates to certain new and useful improvements in post or stake pullers, and it has for its object, among others, to provide a simple, efficient, strong and durable device for quickly and easily extracting a post, stake, pipe, or any other device from the ground or other place where 1t be located. It will befound useful in lift ng a pipe from an oil well or lifting or raising any element by which lt'may be caused to grasp.

The invention has for an obJect, among others, to provide a post or stake puller, of a portable nature, capable of being set up in the desired position and readily applied to the post or rod, the latter being readily lifted and a new grip automatically obtained thereupon after each raising of the post or rod.

It has for a further object to provide a device of this character, quickly adjustable for use upon posts, rods or the like of different diameter and of any cross SGC-tlOIL,

The device embodies two parts, both capable of being manufactured at small cost,

possessing greatstrength, and not requiring skilled labor to apply or manipulate the same.

Other objects and advantages of thelnvention will. hereinafter appear and the novel features thereof willbe particularly out in the appended claims.

The invention, in its preferred form, is clearly illustrated in the accompanying drawing, which with the numerals of reference. marked thereon, form a part of this specification, and in which,

Fig. 1 is a front view showing the device applied to a rod.

Fig. 2 is a side elevation of the same, showing the operating lever and the gripping means in full and dotted line positions.

Fig. 3 is a top plan view of Fig. 2.

Fig. 4 is an enlarged top plan'view with the operating handle broken 01f showing the chain-holding member, which latter serves a further function, soon to be described.

Fig. 5 is a side elevation of the chain-holding member, the operating handle being broken away.

Fig. 6 is a face view of the chain-holdinn member, and

Fig. 7 is a side elevation with a portion in broken lines, showing a modified construction. 7

pointed new Like numerals pertain to like parts throughout the general views.

Referring to the drawings, 1 designates the upright or supporting member which I may vary in the form and construction, butin the present invention shown as being of substantial form, the base 2 of which is designed to rest upon the ground or other support, the side members at theirupper end being drawn parallel to each other and extended slightly above their bend to form the flanges 3 between which is mounted upon asuitable pivot 4,'an operating handle" 5.v

As seen in Figs. 2 and 5, the operating lever 5is extended beyond its pivot to form a short arm 6 to the free end of which is pivotally mounted the member 7. The construction and character of this member 7 will be best understood by reference to Figsia, 5 and 6,

in which it is shown as a combined dog and chain-receiving member, the same having the spaced-apart'jaws or the like 38'( see Fig. 4), between which is pivoted upon the pivot pin a) the 2nd of the short arm 6 of the operating ever The member .7 is formed upon opposite sides of the portion 8 with lugs or ribs 10 see Figs. 4, 5 and 7) to add strength to the same, and what may be termed the forward end of this member, is providedwith the substantially \l-shaped notch 11 and intermedi ate said notch and the rear end of such memher, are openings 12 a1l of which will be clearly seen from reference to Fig. 4-.

Theimember 7 is provided with the upwardly extending portions 13, having open' ings 14 extending transversely and whichserve for the reception of a cotter pin 15, as indicated by dotted lines in Fig. 4 and full lines in Fig. 3. In one form of the invention, soon to be described, the cotter pin forms 1 a double function. In the form shown in Figs. 2, 4. 5 and 6, it serves to prevent displacement of the chain, while in the form shown in 7, it serves not only this last mentioned function, but also serves as the means of pivotal connection between the ends of the short member 6 of the lever and the member 7. It is to. be understood that in this last connection or arrangement, that is, where the cotter pin serves the double purpose above mentioned, the pivot 9 heretofore described as being that upon which the operating lever had pivotal connection with the member 7, is omitted. Y I I bight of the chain depending, and the ends of the chain are then passed through the open ing 17 in the jaws of the member 7, resting upon the walls 18 tllOlGOll, and the cotter pm 15 is disposed above the chain in said open- 1 ings, the chain being first passed around the post or other object 19 to be lifted. V

The full line position of the lever or operating member 5, the member 7 and the chain 16,-is that of the parts prior to manipulation of the member 5. lVith the partsin this position the post or rod 19 is loosely received within the bightof the chain. As the lever is moved from the full line position to that shown in dotted lines in Fig. 2, the post or rod is held'in a tight grip between the bight of the chain and the angular walls of the notch 11, and the post or rod is lifted. The arm 5 then being again raised from the dotted to full line position, the chain is :automatically released. irom its hold on the member 19 andfalls to the full line position, when repetition of these 'n'iovements alternately. gripsand releases the member 19 until it is eventually pulled from the ground.

lVhen the cotter pin 15 is in position over the chain,'the latter is held fixedly in adjusted position. If it is desired to grasp a larger or smaller'post 19 the pin is moved in its bearings'until one end of the chain is disengaged when the same may be moved through its opening in one direction or the other to increaseor decrease the bight oi": the chain.

- In the construction shown in Fig, 7, the operation of the parts-is substantially the same as in the other form but the pin 15' serves both as the pivotal connection between the free end or" the short arm 6 of the operating member 5, and the portion 13 of the member 7.

his to-be noted that the member? is in both instances gravitatingly mounted upon 'the' arm 5, so as to automatically drop into llOlCllIlg'pOsltlOn' thief the lever is moved.

rModificat-ion in detail may be resorted to Without departing from the spirit of the invent-ion or sacrificing any of its advantages.

IVhat I claim is I 1. In a pulling implement, a member having vertical openings and a rod-engaging notch and jaws with openings for the recep tion of a rod-engaging element threaded ing vertical openings, a notch at one end in terspaced with said openings, and passages on the opposite sides 7 or" said openings, and strengthening ribs at said openings, and spaced-apart jaws between said passages.

. .5 A pulling implement comprising-a support, an operating lever pi'votally mounted thereon, a clutch member pivotally carried by said operating member and having a notched free end engage the object to be pulled, and a flexible gripping member carried by the clutch member tocooperate with the said notch form a grip onthe said object. 7

6. A pulling implement comprising support, an operating lever pivotally mounted thereon, a clutch member pivotally carried by said operating lever and having a notched free end to the object to be pulled, and a flexible gripping member carried by the clutch member to cooperate with and acting in opposition to said'notch to form a grip on the said object.

7. A pulling implement in accordance with claim 5 in which the clutch member has openmgs for the passage of said flexible member.

In testimony whereof ture.
