around these and frames provided between .the longitudinal bars and made of angleiron or other similar material. These frames carry notches or recesses into which the longitudinal bars are pressed by means of clips. By the frames the longitudinal bars' are directly adjusted to the exactly calculated position and are immovably retained therein during the stamping process.

The new pole is represented in the accom- ',refer to similar parts throu bout the several views, in one form ofemb iment.

. The Figures 1 and 2'show the pole in front and side view. Fig. 3 is a scenograph of a part of the pole with the concrete broken away here-and there in order to show the reinforcement. Fig. 4 is a section taken on. the direction of the line A to B of Fig." 1.

In the shown construction, the pole a has a rectangular cross-section and it is fitted at zthe broadside in the neutral sphere with the openings 6. These latter are sufficiently big as to allow j to put therein a foot, and to .climb' up to the top of the poles without -special expedients. .The openingspresent still the further advantage that'a saving in material isinsured without affecting in the least the strain-resisting "uality of the pole; they also allow the Win to pass through, thus reducing the wind-pressure.

In the'corners of the pole thereare -ar-: ranged the iron-rods 0 passed longitudinally through it.
