Description
P. J. HARRAH Feb. 5, 1924i POLE PUSHER Filed June 28. 1922 @www Patented Feb. 5, 1924.
POLE PUSHER.
Application filed June 28,
To all 'Lo/wm t may concern:
Be it known that I, PHrLir J. Hannan, oBloomield, in the county of Greene and State of Indiana, have invented certain new and useful Improvements in Pole Pushers; and I do hereby declare the following to be a Jfull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention provides improved means for raising posts and poles and especially for correcting the position of wire supporting poles which are leaning or out of proper alinement.
Figure 1 shows the pusher in operative position. Figure 2 is a cross section on line 2 2, Figure 1. Figure 3 is a detail.
The invention comprehends two telescoping sections, a lower section anchored to the ground, and an upper section to engage the pole, the lower section having means Jfor advancing the upper one.
The lower section is made in accordance with the disclosures of Letters Patent 1,374,- 653 issued to me April 12, 1921, for lifting jack. As there shown, as well as in the accompanying drawing, it comprises a bar or standard 1 having a longitudinal series lof holes 2 extending entirely through its thickness. These holes are to receive pins 12 and 18 carried, respectively, by runners 3, 4, movable on the bar 1. A lever 5 is pivoted to runner 4 and has a pitman 7 pivotally connected with runner 3, whereby the two runners are alternately movable on the bar, the pins 12 and 18 being alternately pressed into holes 2 of bar 1 by springs coiled upon them, as the runners move lon-V gitudinally of the bar consequent upon the action of lever 5.
In the present case VI have shown the bar terminating at its lower end in a channel iron 22 having its flanges to the ground and formed in its bodyportion with al hole large enough to engage the end ofthe bar but not large enough to permit it to pass entirely through.
The bar 1 is I-shape in cross section. The runner 4 encloses the bar and at its 1922. Serial No. 571,486.
top projects laterally well beyond the bar and forms an eiective seat .23.
24 is the upper section of the device. It is shown as a cylinder telescoping the bar and resting upon the seat aorded by the runner 4. At its outer end this cylinder has a head 25 formed with a plurality of points, Figure 3, to prevent the pike entering the pole 26 too far.
The operation is obvious. The advantages are that the tube or cylinder 24 is in exact longitudinal alinement with the bar 1 so that there is no tendency to lateral strain; that the cylinder acts as a guide for the bar and prevents any tendency to buckle at the joint; and that the bar may be turned axially'at any time so that the lever 5 may be operated from any angle.
It will be noted that no extra parts are needed and that the sections may be separated or assembled without removingV a single screw or bolt.
l claim as my invention:
1. ln a pole pusher, two telescoping sections in longitudinal alinement, the upper section to engage a pole and consisting of a cylinder, and the lower section to be anchored tothe ground and comprising abar projecting into said cylinder, and a runner movable on said bar and constituting a seat for said cylinder.
2. A pole pusher comprising a bar,v a runner movable on said bar, a seat carriedA by the upper end of the runner, and a cylin drical member resting on said seat and into which said bar projects.
3. A pole pusher comprising a bar, a runner movable on the said bar, means moving said runner step by step on said bar, the upper end of the runner having a seat, a cylindrical member removably supported in the seat and into which extends the upper end of the bar. y
4. A pole pusher comprising a bar, a runner movable on said bar, means for moving the runner step by step on said bar, a foot Jfor the lower end of the bar, and a cylindrical member having a pointed up per end, and a seat carried by the upper end of the runner adapted to removably support the lower end of the cylindrical n'lelnber yand. said bar extending into said cylindrical member.
5. A pole pusher, comprising an I-bzu', L runner movable 011 said bar, means for moving the runner step by step on said bar, a foot for the lower end of the bar, a cup-shaped seat carried by the upper end of the runner, und u cylindrical tube ol an interior diameter to receive the -bur whereby the tube s held against any twisting action on the bur and is free to move longitudinally thereof,
In testimony whereof l have signed this speeiicaton.
PHILP J. HARRAH.
