525,031 able shafts which may be driven synchronously by the worm gearing, N, from a central power shaft, n.

The base of the tower is embedded in ,the e ground to a desired depth and from a distance above the base extend anchoring bars or rods, 0, connected to plates, o, embedded in the ground, while the base is further anchored by a series of cross bars, O', extending through i o the base portion of the tower beneath an inner horizontally disposed ring, o', held in position against the same by bolts, o², extending through a plate, o³, placed on the. surface of the ground and forming a bed plate for the i j hoisting machinery.

The passenger platform, J, is annular in form and is provided at each edge with inclosing hand rails,/, and on its underside has supporting wheels, h', adapted to thecir2o cular tracks, h, of the hoisting platform, H;

in order to prevent any lateral movement of the passenger platform the hoisting platform carries at points just below it upper guiding rollers, m, a circular track, P, against which 25 the antifriction rollers,p,‘ carried by the passenger platform may travel, these rollers and the track, P, serve to keep the rollers, h', upon their tracks, li, so that it is unnecessary to emplov flanged rollers for the purpose.

₃o The mechanism for revolving the passenger platform is of any suitable character, a preferable form being that illustrated wherein the hoisting platform, H, is extended out at diametrically opposite points to form, on one side a support, Q, for an electric motor, R, and on the opposite side to form a support, q, ?for a grooved idler, r, the motor being g’eared down and adapted to revolve a pulley, τ' from which extends a wire cable belt, S, 40 adapted to a groove, s, in the edge of the platform, J, the cable or belt extending also around the idler, r,so that the pulling strain of the cable will be equalized and the passenger platform will not be pulled over to45 ward the motor. The motor may, however, be carried by the passenger platform and drive a rolle/or cable operatively connected to the passenger platform or tower, or a gas engine or other motor may be employed for co thepurpose. In some cases the vertical move³ ment of the . platform may be transformed into a revolving motion and the platform be revolved without any auxiliary motor power as^!will be readily understood. The necessary e e electric current for the motor may be trans³³ mitted through a flexible cable, such as is ordinarily used for lighting purposes in passenger elevators, or it may preferably be sup-: plied by a trolley wire, T, provided vertically: 60 upon the outer walls of. the tower and against which may bear a trolley wheel, t, carried by an arm, t', pivoted to the under side of the platform, H, and held in contact by a spring or other suitable device. In operation the 6c passengers are assembled on the platform, J, at the base of the tower and after the hoisting drums have been started in motion the.

electric motor upon the platform, H, is set in operation and as the hoisting platform is raised to the top of the tower and with it the 70 passenger platform, the latter is revolved at any desired speed by means of the motor and its cable, S, so that the passengers while ascending or descending will at the same time also be rotated horizontally and during the 75 ascent and descent of the platform may have an uninterrupted view from all sides of. the tower; the platform at the extreme top of the tower may be employed when the passengers desire to remain at the top, and there may, if 80 necessary, be intervening platforms at various heights within the tower proper when the latter is of any great height.

For the convenience of passengers I may provide a number of revoluble or other seats, 85 and the platform may be stepped, as illustrated in Fig. 1.
