4 Claims.

This invention relates to apparatus for handling poles and more particularly to apparatus for raising and setting poles of the types generally used tov support telephone and telegraph lines.

The primary object of this invention is to provide pole setting apparatus which is adaptable to being operated by one man. I

Another important object of this invention is to provide pole setting apparatus which one man can readily and quickly dismantle, load into a conveyance for transportation from place to place, and reassemble.

A further important object of this invention is to provide pole setting apparatus which is simple in design, rugged in construction, and inexpensive to manufacture.

-A still further important object of this invention is to provide pole setting apparatus which is light in weight but is adapted to withstand rough usage.

These and additional objects and advantages will be apparent from the following description and annexed drawings, which describe and illustrate a preferred embodiment of the present in-' vention, and wherein:

Figure 1 is a rear elevation view of the apparatus constituting my invention,

Figure 2 is a side elevation view,

Figure 3 is a plan view,

Figure 4 is an enlarged vertical section view.

taken about a long line 4-4 in Figure 1.

Figure 5 is a perspective view of the saddle and illustrates one type of boomer which is suitable for the purposes of this invention.

Figure 6 is an elevation view of the block and tackle system used to raise the butt end of a pole and dispose the pole at, a point intermediate its ends on the saddle.

Figure 7 is an elevation view depicting the block and tackle system illustrated in Figures 1 and 6 in a rearranged form for operating on the butt end of a pole to tilt the same about the pivoted saddle into a substantially vertical position 45 with the butt end down.

Referring to the drawings, a number of lengths of steel tubing III, of suitable size and strength,

are assembled through the agency of T-unionsll, elbow joints l2, and welded joints Hi to form a rigid base. It is to be clearly understood that although I prefer to use tubing in the'practice of this invention, various other structural shapes, such as angle,'channe1, or T iron may be employed if desired. Mounted in T-unions H in the base and projecting upwardly therefrom, are

a pair of, tubular legs H, which are connected at their upper ends by elbow joints l5 to a horizontal cross member It. A saddle I1 is pivotally supported by cross member "5. Two sections of chain indicated by reference numeral I8 and a conventional type of clamp l9 constitute a boomer for firmly holding a pole on the saddle.

A pair of tubular braces 20 extend from T- unions II at the rear of the base to T-unions 2| in the horizontal cross member 16. A similar set of braces 22 is attached by

bolts

23 and 24 to the base forelegs and tubularlegs I4, respectively. The lower end of a mast, such as tubular gin pole 25, fits over a positioning pin 26 and rests upon the base tubing. The gin pole is also removably connectedto one of the braces 20 by a bolt 21. It is apparent that with this arrangement, a sturdy type of construction is obtained. Furthermore, by means of couplings 28 and

bolts

23, 24 and 21, the framework and gin pole can be easily and quickly dismantled and folded compactly.

Secured to the braces 20, at a convenient height above the base is a pair of brackets 29 which journal shaft 30 of a winch drum 3|. Rotation of the drum is attained through a crank 32, a pin- -ion'33 connected to the crank, and a gear 34 which is mounted on shaft 30 and is in engagement with pinion 33. The winch operates a block and tackle system, consisting of a rope, chain, or cable 35, a single sheave block 36 which is fastened to an eye 31 in the frame base, a double sheave block 38 which is shown suspended from the mast by a hook 39, and a single sheave block 40. A pair of log hooks 4| is carried by block 40.

'Proper design of the winch mechanism, together with the block and tackle system disclosed, obviously provide the necessary mechanical advantage to enable one man to readily raise various sizes of poles, including heavy poles, such as creosoted long leaf yellow pine.

In the operation of the instant invention, the apparatus is first set up as shown in Figures 1, 2, 3 and 6 of the drawings so that the pole hole is within the open front end of the base and directly below the saddle H. The pole is then placed along the side of the base frame opposite the winch crank 32 with the butt extending in front of the apparatus, a distance approximately equal to the distance from the top of the gin pole 25 to the ground. The log hooks 4| are lowered and fastened to the pole near the butt end. The crank is then turned in a clock-wise direction with the result that the force exerted thereon will be transmitted through the pinion, gear, and

drum mechanism to the block and'tackle system; and the pole is thus raised until the butt is above the framework and the pole is seated in the saddle. The pole is next securely strapped to the saddle by means of the boomer.

-The pole is now in a position for tilting the same about the axis of the pivotally supported saddle I1 until the pole is in a substantially vertical position above the hole with its butt end down and its top end up. There are several methods of procedure for accomplishing this objective with the equipment described herein-the following covers one method:

This method contemplates utilizing my apparatus to pull downwardly on the butt end of the pole. The block and tackle system is first rearranged as shown in Figure '7. This is done by removing hook 39, together with double sheave block 38 which is attached thereto, from the top of mast 25. Log hooks M are next detached from block 40 and placed on hook 39. The log hooks are then fastened to the butt end of the pole so as to securely grip the same. Single sheave block 40 is connected to eye 31. It is to be noted that eye 31 in the base structure now has the two single sheave blocks, namely 36 and 40, fastened thereto. With the above described rearrangement of the block and tackle system, winch crank 32 is again turned in a clock-wise direction. It will be evident that a downward pull is thus imparted to the double sheave block, the log hooks, and finally to the pole. When the pole is swung to a vertical position, the boomer is loosened and the pole is permitted to slide downwardly into the hole.

It is to be understood that the form of my invention, herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention as defined by the appended claims.

I claim:

1. In pole setting apparatus, the combination comprising a saddle, a support therefor, said saddle being pivotally connected to said support, means for securing a pole to said saddle, and means for raising the butt end of said pole to seat said pole at a point intermediate its ends on said saddle and for thereupon pulling downwardly on the butt end of said pole to pivotally actuate said saddle and tilt said pole to a substantially vertical position with its butt end down.

2. In pole setting apparatus, the combination comprising a, saddle, a support therefor, said saddle being pivotally connected to said support, means for pulling upwardly the butt end of said pole and seating said pole at a point intermediate its ends on said saddle, means for securing said pole to said saddle, and means for pulling downwardly said butt end of said pole to pivotally actuate said saddle and tilt said pole to a substantially vertical position.

3. In pole setting apparatus, the combination comprising a saddle, a support therefor, said saddle being pivotally connected to said support, means for pulling upwardly the butt end of said pole and seating said pole at a point intermediate its ends on said saddle, means forsecuring said pole to said saddle, and means for pulling downwardly said butt end of said pole to pivotally actuate said saddle and tilt said pole to a substantially vertical position, said flrst and third men tioned means including a common winch and a common tackle.

4. In pole setting apparatus, the combination comprising a frame; means carried by said frame including a tackle, a plurality of blocks and means for engaging the butt end of a pole; said first mentioned means being so arranged that upon actuation of said tackle said engaging means is moved upwardly toraise the butt end of said pole and place said pole at a point intermediate its ends on said frame; said tackle, blocks and engaging means being adaptable at will to be rearranged with respect to each other so that upon actuation of said tackle said engaging means is moved in the opposite direction to pull the butt end of said pole downwardly.
