J. P. PERKOWSKI POLE SHIFTING DEVICE Filed Oct. .29, 194Q 3 Sheets-Sheet 3 fl gaf Inventor J54 2Z4 274m Attorney Patented July 22, 1941 UNETEI STATES OFFICE 3 Claims.

This invention relates to a pole shifting device, the general object of the invention being to provide an attachment for a truck or the like whereby poles can be shifted from one place to another or poles easily handled in placing them in holes and removing them from the holes, the invention being mainly designed for shifting high tension line poles without danger of the pole kicking out at the butt as the pole is being shifted.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts tobe hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an elevational view showing the device on a truck and in use for moving a pole.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a top plan View of the rear part of the truck and showing parts of the device in plan, parts omitted and parts in section.

Figure 4 is a View of the outer end of one of the ring supporting arms.

Figure 5 is a section on the line 55 of Figure 3.

Figure 6 is a detail sectional view showing how a brace of the boom engages a bracket at the lower end thereof.

Figure '7 is a View showing the ratchet means for the drum with the shaft in section.

Figure 8 is a section on the line 8-8 of Figure 2.

In these views the numeral I indicates a bracket connected to the floor of a body of a truck T and the numeral 2 indicates a bar pivoted to the bracket and having a row of holes 3 therein. A tubular bar a telescopes the bar 2 and has a pin 5 therein for engaging anyone of the holes 3 so that the length of the boom formed by the parts 2 and 4 can be adjusted. The upper end of the boom is forked and has rotatably supported in the space between the prongs of the fork a pulley 6 and braces l have their upper ends pivoted to the upper end of the boom preferably by the shaft 8 which rotatably supports the pulley in the upper end of the boom. These braces I extend downwardly and outwardly toward the sides of the truck at the rear end thereof and these braces have fiat ends provided with notches 9 which fit over the horizontally extending rod or bar It which is connected by the brackets H to an angle plate l2 attached to the rear of the truck body as shown more clearly in Figure 1.

The flattened ends of the braces I extend into U- shaped brackets but the bar or rod I!) is further supported by the brackets II and a central bracket II. The brackets H are placed inwardly from the brackets I and tubular sections it of telescopic arms M are pivoted to these brackets H as shown at H5. The outer sections of the arms 14 are shown at 16 and have holes I! therein for receiving pins l8 carried by the sections I3 so that these arms can be adjusted as to the length. A sectional ring [9 has ears 2!] on one of its sections to which the sections l6 are pivoted as shown at 2| and the ring is composed of the sections 19 and I9" and the two sections are connected together by the bolts 22.

A drum 23 is rotatably supported in the truck body adjacent the front thereof by a supporting member 25 and this drum is provided with a ratchet mechanism 25 as shown more clearly in Figure 7 and it may be turned in any suitable manner either by handles 26 or power means or from a power driving part of the truck. A cable 21 is wound upon the drum and extends upwardly over the pulley 6 and then downwardly where it receives a loop 29 to fit around the pole P as shown in Figure 1.

Brace members 31 are pivotally connected to the lower ends of the brace members 1 by rings 32 clamping the members 1 and to which the front ends of the members 3| are pivoted as shown at 33 and clamping devices 34 are pivoted to the front ends of the members 3| as shown at 35 in Figure 5 and these clamping devices clamp the arms l3 so that the arms [3 are supported from the braces I as well as from the bar II]. In using the device the section I9" of the ring I9 is removed and then the truck is backed up against the pole to partly place the pole in the section l9 of the ring. Then the section I9" is bolted in place but in such a manner as to have the ring loosely fit the pole so that the pole can slide free. The cable is then looped around the upper portion of the pole as shown at 29 in Figure 1 and then the drum is started to wind the cable thereon so that the pole will be lifted from one hole and can be placed in another. However, in placing the pole in the new hole the two sections of the ring should be tightened to prevent free swinging movement of the pole.

As will be seen the parts are detachably connected together so that they can be separated and th entire device placed in the truck for transportation purposes when not in use. While the invention is mainly designed for shifting poles it can be also used for handling poles of various kinds and other large pieces of material.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall Within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A pole handling device comprising a boom, means for pivotally connecting one end of the boom to the body of a vehicle, a pulley at the other end of the boom, supporting means adapted to be attached to the rear of the body of the vehicle, braces extending upwardly from the supporting means and pivotally connected with the boom, arms extending from the supporting means, a sectional ring carried by the arms, braces connecting the arms with the lower ends of the braces of the boom, a drum, a cable thereon passing upwardly over the pulley and adapted to be connected to an object which is engaged by the ring.

2. A pole handling attachment for a truck comprising a boom adjustable as to its length, means for pivotally connecting the lower end of the boom to the body of a truck, a pulley carried by the other end of the boom, a rod, means for supporting the rod at the rear end of the truck in horizontal position, brackets connected with the rod, braces for th boom extending downwardly and engaging the rod and the brackets, a pair of sectional arms pivotally connected with some of the supporting means, a sectional ring carried by the arms, braces connecting the arms with the lower part of the braces extending from the boom, means for fastening the sections together, a drum in the body, a cable thereon passing upwardly over the pulley on th boom and means for fastening the cable to the pole which is engaged by the ring.

3. In a pole handling attachment for a truck comprising a boom having one end pivotally connected with the body of the truck, a pulley at the upper end of the boom, supporting means at the rear of the body, an arm connected with said supporting means for pivotal movement, a pole clamping ring connected with the outer end of the arm, a member connecting the other end of the boom with the supporting means at the rear of the truck, means for connecting the lower end of said member with the arm, a drum in the truck, a cable thereon passing over the pulley at the upper end of the boom and connected with the pole which is also encircled by the ring.
