Allorwy UNITED STATES PATENT OFFICE.
GEORGE D. AIKEN, or SALT LAKE CITY, UTAH.
PORTABLE POLE-STEP.
SPECIFICATION forming part of Letters lateht No. 601,849, dated April 5, 1898.
Application filed June 12, 1897- Serial No. 640,556. (No model.)
To all whom it may concern: 4
Be it known that I, GEORGE D. AIKEN, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake, State of Utah, have invented certain new and useful Improvements in Portable Pole-Steps, of which the following is a description, reference being had to the accompanying drawings and to the letters of reference marked thereon. I The invention relates to a portable step for telegraph and other poles.
The objects of the invention are to provide a pole-step which may be readily removed from and inserted in its holder, to so construct the step as to prevent the operators foot from slipping, and to form the step-holder so that it cannot be used by unauthorized persons as a step when the proper step has been removed. My invention consists in the construction and combination of parts hereinafter described and claimed.
Referring to the drawings, Figure 1 shows a portion of a pole with my step applied. Fig. 2 shows the step, in plan and side elevation, removed from its holder. Fig. 3 shows the step-holder in plan and side elevation, and Fig. 4. is a front elevation of the step-holder.
A is the portable step, comprising the horizontal tread a. and the vertical depending at taching shank a. This step is preferably formed of a single casting, and the top of its tread is slightly concave and formed with transverse teeth a which incline toward the inner end, so as to better prevent slipping of the foot.
Bis the step-holder or fixed member of the step and comprises aspike B, provided with a vertical plate B to limit its inward movement, said plate being provided at its lower corners with forwardly-projecting lugs 17 b and an aperture b therebetween to receive of the spike is provided with a vertical angular socket b to receive the shank a of the step A, while the-lower end'of the shank extends between the two lugs 1) b so that all loose movement of the step is prevented and its rigidity assured. The side edges of the head B are connected with the upper portion of the plate B by means of the inclined flanges b. These flanges receive the inner end of the tread a between them and brace the head of the spike; but they also effectually prevent the holders from being used in the absence of the stepsA by presenting an inclined surface, from which the foot will slip. The steps A maybe easily carried in the belt of the lineman and readily applied to the sockets b and after use the steps may be removed and access to the top of the pole prevented.
The two parts of my improved step may be cast or swaged, require no boring or drilling, and maytherefore be very economically manufactured.
What I claim is- 1. A holder for pole-steps and the like comprising'a spike having a head provided with an opening therethrough, and a plate at the inner end of said head extending in the direction of the-opening, whereby a shank upon a pole-step can be inserted through the opening and rest against the plate; substantially as described. V 2. A holder for'pole-steps and the likecomprising a vertical plate, ahead upon said plate below its upper edge and extending at an angle to the plate, said head being provided with an opening for receiving a suitable portion of the step, an inclined wall between the vertical plate and the outer end of the head, and means for securing the holder to a pole or other member; substantially as described. 3. A holder for pole-steps and the like comprising a spike having a head provided With a vertical socket, a vertical plate to bear on the pole, forwardly-projecting lugs on the plate below the head and inclined flanges connecting the plate and head at opposite sides of the socket; substantially as described. the nail G, as shown in Fig. 1. The head B GEORGE D. AIKEN.
