To @Z310/tom z' may concern:
Re it known that we, JOHN L; FAY and Fnnonrcn BIELHEN, citizens of the United States, residing at St. Louis, Missouri, have invented a certain new and useful improvement in Pole-Erectors, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
Our invention relates to an apparatus for erecting poles which carry the overhead wires and cables utilized in telegraph, telephone and electric-light service, the principal object of our invention being to provide a comparatively simple apparatus which will be eective in eliminating much of the time, labor and consequent expense now involved in the erection ot poles, said apparatus being mounted on a truck in order that it may be readily moved to and Jfrom the points of use and the operating parts of the apparatus being adjustable upon the bed of the truck in order to facilitate the work involved in the erection of poles. j
Further objects of our invention are to provide an improved pole erecting device which includes a gin pole, the same being equipped with a suitable block and tackle which is utilized in lifting the poles which are to be erected to mount the gin pole and its operating mechanism upon a base and to mount the latter for transverse sliding movement upon the rear portion of the bed or platform of the truck utilized for transporting the erecting device, and Vfurther toV provide means preferably cooperating racks, pinions and worm gearing for readily shifting the gin ole from an approximate horizontalposition on the bed of the truck to a vertical position or vice versa and for raising or lowering the gin pole for a limited distance after it has been swung into a vertical position. By utilizing coperating racks,` pinions and worm gearing as the means for raising and lowering the gin pole,
weare able to dispense with cables, winding drums, clutches and like parts usually em-.
ployed for raising and lowering the gin ole. j
With the foregoing and other objects in view, our invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which- Figure 1 is an elevational view or' a truck, the same being equipped with a pole erectfig device et our improved construction.
Fig. 2 is an enlarged side elevational view or" the rear portion of the bed 01"' the truck and showing the operating parts of the erecting device.
Fig. 3 is a vertical section taken approximately on the line 3--3 of F ig. 2.
Fig. a is an elevational view partly in section and showing the gin pole in vertical position. j
Fig. 5 is an elevational view looking in the direction indicated by the arrow 5 in Fig. t, and showing the lower end of the gin pole in section.
Fig. 6 is an enlarged horizontal section taken approximately on the line 6--6 of Fig. 4. Y i
Referring by numerals to the accompanying drawings, 10 designates the bed of a truck, either horse-drawn or motor-driven and fixed to the rear ond of said bed and extending the entire width thereof is an angle rail 11.
VFixed on top of the bed a short distance in front of this angle rail `and occupying a position parallel therewith is a Z-bar 12, and xed to the bed immediately adjacent to said angle and Z-bar are straps 18.
Arranged for sliding movement upon these straps and between thel members 11 and 12 is a plate 111: which serves as a base for the operating mechanism of our improved device.
Fixed to plate 1d are pairs of upwardly j projecting brackets 15, the upper ends of which are provided with journal boxes 16 which receive the ends of a shaft 17 and mounted on this shaft between the journal box is a quadrant plate 1S, the same being provided with teeth 19.
Formed integral with or xed to this quadrant plate is a pair or rack bars 20, with the ends of which are formed integral blocks 20a, the same having sliding connec` tion, Vpreferably with a rib 21, which latter is formed integral with a plate 22, the latter being rigidly lixed in any suitable manner to the lower portion of a gin pole 23.
`Asillustrated, the blocks 20L have dovetailed joint connections with the rib 21, al-
though-1 any other fol-ln of sliding eonneetion may be utilized as desired.
Fixed to the bottom ot the gin pole23 is a plate 24 with which is formed integral one 5 or more prongs 25, the saine being adapted to enter the ground on which the gin pole is positioned, thereby assisting in maintaining said pole in a rigid and substantial upright position. The upper end oiitlfie' gin pole is 10 provided with a sheave 26 around which passestlie cable 27 of a bloeit and' tackle (not sli-own). Fixed to thenpper end of thegiir pole are rings or eesQS, "Wl'iiclr'are adapted to" receive guy ropesor the likeutilfi-Zcd for l5' stajf'ing" the gin pole When the's'aine is in op;
Positioned between' rib :'21 and the `rack barsQ' is a fnielnloer comprising a centrally arranged Worin Wheel 29 and a `pfair" of pin! 2o' ions 20, which latter are constantly 'inL inesh Wlfjlitli'teetl'lpf tllclfbirs 20.

sult that the gin pole is swung downward into a substantially horizontal position as illustrated in Fig. l.
1t will be understood that the weightl of the gin pole while in a vertical position and before its lower end rests upon the ground, ist 1ansmitted through worm 33, worm wheel 29 and pinions 30 to rack bars 20, from thence through shaft 17 and brackets supporting the same to plate le, which latter rests upon the bed of the truck, and further that this arrangement of parts particularly the worm and worm wheel practically locks the gin pole against downward movement by reason of its weight, after said gin pole has been swung into a vertical position and before it has been lowered into contact with It will be noted that we employ means, preferably a pinion and toothed. quadrant plate, for shifting the gin pole from a horizontal to a vertical position and vice versa, and that we provide a Vdifferent means which preferably includes coperating racks, pinions and worm gearing for raising or lowering the gin pole after it has been swung into a vertical position. By virtue of these mechanisms, all cables, winding drums, clutches and the like usually employed for the gin pole raising and lowering means are eliminated and the raising and lowering operations can be effected quickly and with comparatively little effort on the part of the operators.
A pole erecting apparatus of our improved construction is comparatively simple, can be easily and quickly shifted into and out of operative position, can be readily -moved from one side of the truck to the other, and by its use a material saving of the time, labor and consequent expense now involved in the setting of wire carrying poles is eifected.
It will be readily understood that minor changes in the size, form and construction of the various parts of our improvedpole erecting apparatus can be made and substituted for those herein shown and described, without departing from the spirit of our invention, the scope of which is set forth in the appended claims.
