2,733,895 Patented Feb. 7, 1956 2 of the forward end of the peavey With respect to a peavey Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the different views of the drawings.

Referring now to Figures 1 through 4, inclusive, it is seen that there is illustrated a modified form of support which is referred to in general by the reference numeral 10. The support 10 includes a front member 12 which is formed of a plate and which has a forwardly'sloping lower portion 14. The upper portion thereof is adapted to extend substantially vertical and is integral with the lower portion 14, the upper portion being referred to by the reference numeral 16.

Extending rearwardly from the front member 12 at the intersection between the lower portion 14am the upper portion 16 is a centrally located rearwardly projecting horizontal member 18. The horizontal member 18 is in the fornrof a generally rectangular bar and has secured thereto adjacent the forward and rear ends thereof transversely extending bars 20 and ZZfrespeC- tively. The bars 29 and 22 have centrally located re- It will be understood that the horizontal member 18,

and the elements thereon form a peavey socket and are adapted to receive the forward end of a peaveyl Inasmuch as the forward end of a peavey is tapered, the recess portion 24 and the bolt 28 are ofpa smaller diameter than the recess portion 25 and the bolt 30, respectively.

In order that the forward end of a peavey maybe partially supported by the front member 12, the upper portion 16 thereof is provided with an opening' iiti. The ope in 36 is generally diamond shapedand is in alignment with the peavey socket.

In order that the horizontal member 18 may resist bending stresses, the rear end thereof has connected thereto a horizontal portion 38 of a diagonal "bracelgltl The diagonal brace 40 slopes downwardly and forwardly from the rear end of thehorizo-ntalmember 13 and ,is secured to the lower portion 14 of the'fron t member 12 adjacent its lower edge and intermediate the side edges thereof. i Referring now to Figures 2 and 3 inparticular, it be seen that there is'illustrated a peavey which ,is referred to in general by the reference numeral 42. The peavey 42 includes an elongated handle 44iw ich terminates at its forward end in a pointed pick member fi-S. The forward end of the handle and a, portion of the pick member are enclosed in a conical sleeve 46 secured to the handle. Carried by the sleeve intermediate its ends is a mounting bracket 48. Pivotally connected to the mounting bracket 48 bya pivot pin 50 is a longitudinally extending log hook 52'. i i

When it is desired to utilize the timber jack, which is the subject of this invention and which is forrnediof the support it) and the peavey 4 2, the support 10 is secured on the forward end of the peavey42 by sliding the sleeve 46 through the inverted U-shaped bolts 28 and 3t) and the opening 36. Then by tightening down on the nuts 3} and 34, the same is rigidly clamped to the support 10.

:When it is desired to elevate a log, such as the log 54 for cuttingthe same into shorter lengths, the point of the peavey 42 is rested upon the ground whilerthe hook 52 is engaged with the log54. Then by rotating the handle 44 of the peavey 42 in a counter-clockwise direction, as viewed in Figure 2, to the position illustrated in Figure 3 it will be seen that the log 54 is raised .to an elevated pesitign with respect to thegroundandthat the sanie -is supported on the timber jack. When so positioned, the rear end of the handle 44 of the peavey and the bottom of the front member 12 rests upon the ground to form asatisfactory support for the log 54.

Referring now to Figures through 8, inclusive, it will be seen that there is illustrated a form of support which is referred to in general by the reference numeral 56. The support 56 includes a front member which is referred to in general by the reference numeral 58 and a rearwardly extendingpeavey socket whichis referred to in general by the reference numeral 60;

The front member 58 is intended to be disposed in substantially a vertical plane and includes a transversely extending base member 62 which is formed by an angle member. Extending upwardly in converging relation from the base 62 intermediate its ends is a pair of leg members 64. The leg members 64 are connected together intermediate their ends by a strap 66 and their upper ends are separated with the portion above the strap 66 forming an open space 68 whose purpose will be explained in more detail hereinafter.

The peavey socket 60 includes a pair of rearwardly extending horizontal angle members 70 which open upwardly and towards each other. The angle members 70 have their forward ends secured to the legs 64 above the strap 66 by suitable fastening means including welding. Extending between the angle members 70 adjacent the front member 58 is a transverse strap 72. The transverse strap 72 is secured to the underside of the angle members 70 and has secured thereto an upwardly extending inverted U- shaped bolt 74. It will be understood that the bolt 74 is provided with nuts 76 adjustably secured thereon to produce a clamping action.

Extending between the rear ends of the angle members 70 and secured to the undersides thereof is a rear strap 78. The strap 78 also has connected thereto an upstanding inverted U-shaped bolt 80. In order that a clamping action may be produced with the bolt 80, it has threadedly engaged on the lower ends thereof a pair of nuts 82.

In order that the peavey socket 60 may resist bending with respect to the front member 58, there is provided a pair of rearwardly extending upwardly directed diagonal bases 84. The diagonal bases 84 each extend from one of the legs 64 adjacent the intersection with the base 62 to the lower side of an associated angle member 70 adjacent its connection to the strap 78.

When it is desired to clamp the support 56 of a peavey, such as the peavey 86, a conical sleeve 88 thereof which is mounted on the forward end of a handle 90 is passed within the peavey socket 60. The length of the conical sleeve 88 is such that it passes through the U-shaped

bolts

74 and 80 with the pointed pick 91 thereof passing into the open space 68. When the forward end of the peavey 86 is so positioned, it is securely clamped to the support 56 by the inverted

U-bolts

74 and 80.

It will be noted that the conical sleeve 88 has secured thereto intermediate its ends a mounting bracket 92. Pivotally connected to the mounting bracket 92 by a transverse pivot pin 94 is an arcuate hook member 96, the hook member 96 extending longitudinally of the peavey 86.

Referring now to Figure 6 in particular, it will be seen that the pointed end of the conical sleeve member 88 is in engagement with the ground and that the hook member 96 is engaged with a log 98. When so positioned, the handle of the peavey 86 is rotated in a counter-clockwise direction, as viewed in Figure 6, to the position illustrated in Figure 7. When the timber jack which consists of the suport 56 and the peavey 86, is so rotated, the log 98 is raised to the position ilustrated in Figure 7 whereby the same may be readily sawed into shorter lengths. It will be seen that the engagement of the peavey 86 and the support 56 with the ground is such that the log 98 will be rigidly supported.

While the peavies 42 and 86 have been illustrated and 4 t described as being clamped to their respective supports, it will be understood that the supports need not be permanently secured to the peavies. When it is desired to utilize the peavies without the support, the supports are removed by merely loosening up On the nuts of their respective U-bolts and the peavies pulled rearwardly therefrom. r

The operation of this device will be understood from the foregoing description of the details thereof, taken in connection with the above recited objects and the drawings. Further description would appear to be unnecessary. a
