3 Claims.

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

The present application i a division of my pending application, Serial No. 209,591, filed May 23, 1938, entitled Apparatus for setting poles.

The primary object of this invention is to provide a method whereby poles may be readily and quickly erected.

This and other objects and advantages will be apparent from the following description and annexed drawings, which describe and illustrate a preferred embodiment of the present invention, 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 along 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 with the butt end down.

Referring to the drawings, a number of lengths of steel tubing ll], of suitable size and strength, are assembled through the agency of T-unions l I, elbow joints I2, and welded joints 13 to form a rigid base. Mounted in T-unions H in the base and projecting upwardly therefrom, are a pair of tubular legs l4, which are connected at their upper ends by elbow joints IE to a horizontal cross member 16. A saddle I1 is pivotally supported by cross member l6. Two sections of chain indicated by reference numeral l8 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 2i i in the horizontal cross member 16. A similar set of braces 22 is attached by bolts 23 and 24 to the base forelegs and tubular legs 14, 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 connected to 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 3i. Rotation of the drum is attained through a crank 32, a pinion 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 operationof 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 ll. The pole is then placed along the side of the base frame opposite the winch crank 32 with the butt extending in front 5 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 l1 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 hereinthe 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 4| are next detached from block 40 and placed on hook 391. 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.

While the instant invention comprises the several steps and the relation of one or more of such steps to each of the other enumerated steps, it is to be clearly understood that various changes in a method of procedure may be resorted to Without departing from the spirit of the invention as defined. by the subjoined claims.

I claim:

1. In the method of setting a pole, the steps comprising elevating the butt end of the pole by means of a suitable block and tackle system, resting the pole on a support intermediate its ends, rearranging the block and tackle system, and actuating the rearranged block and tackle system to apply a downward pull on the butt end of the poleto tilt the same to a substantially vertical position.

2. In the method of setting a pole, the steps comprising pulling upwardly the butt end of the pole by means of a suitable block and tackle system, resting the pole on a support intermediate its ends, securing the pole to the support, rearranging the block and tackle system, and actuating the rearranged block and tackle system to apply a downward pull on the butt end of the pole to tilt the same to a substantially vertical position.

3. In the method of setting a pole, the steps comprising raising the butt end .of the pole by means of a suitable block and tackle system, resting the pole on a support intermediate its ends, rearranging the block and tackle system, securing the pole to the support, and actuating 1e rearranged block and tackle system to apply a downward pull on the butt end of the pole to tilt the same to a substantially vertical position.
