r This invention relates to `'steps for vtelephone or other. poles, and more particularly to steps'of the detachable type.
One o ftlieobjecfts of the invention istlie provision of apole-step that lmay be readily inserted in and removed from a base-plate vwhich may .be permanently secured to a pole, and-to forni the base-plate Vso that it cannotbe usedby unauthorized persons for climbing Vthe pole when the pole-step is will be .apparent from the `following/"description, when considered in .connection with the' accompanying drawingiii which one embodiment thereof is illustrated.
In `the drawing, Figure 1 illustrates a ypole having `a baseJplate secured thereto,
f vspectively, provided at either' end of the y dimension and a number of these steps may. 1 V9i? with the detachable step in position; Fig. 2 is a front view of thebase-plate lying in a horizontal position ;.'Fi`g. 3 is a view of the step which is adapted to'pbe attacliably positioned intlie base-plate, and Fig. 11 is a` sectional view of the step taken on the Vline 4 4 of Fig. 3.
Referringfto the drawing, the numeral 5A indicates a pole'pivliicli 'is illustrated for. the purpose of showing the applicationv oftlie improved arrangement.. The base-plate 6 may be `permanently attached to the poleV 5 by nieansof bolts or screws andS, which pass through transverse holes 9 and 10 rebase-plate 6. The upper vertical portion 11 of the basefplate 6 rests flatly-against the surface of the pole 5 for a suiiicient distance to 4 perinittlie seating;- ofthe flat inner surface vof the head of the bolt or screw 7. The plate 6 is bent slightly atthis point so that, the portion 12 extends outwardly therefrom in a sloping direction .to a lateral shoulder, which projects Vhorizontally from the lower vertical portion 13. The portion 13 is formedsimilar tothe portion 11 of the plate 6, and likewise rests. flatly against the pole 5 for a sufficient` distance to permit the seating' of tlie flat surface of tlie head` of the bolt or screw 8. f
The portionV 12 of thel plate is provided Witli a transverse opening 14, which is substantially circular, and a longitudinal Vslot- 15 extends downwardly therefrom. The opening and slot are provided forl tliezre- Vception of the step 16, which isv adapted to be` detachably associated therewith.
