Specification of Letters Patent.

Application led August 28, 1919. Serial No. 320,391.

To @ZZ whom it may concern: n

Be it known that I, ERNEST KoHLER, a citizen of the United States, residing at Denver, in the county of Denver land State of Colorado, have invented certain new and useful Improvements in Amusement Devices, (Revolving Talking Beam;) and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to amusement appa^ ratus and more particularly to that type of apparatus comprising a beam having arrangements for carrying passengers.

It is one of the objects of the present invention to provide a simple, practicable, substantial and attractive forni of amusement apparatus in which the traveling member or walking beam is given a movement subjecting the passenger to the sensation of a rolling or wave like movement.

Another object of the present invention is to provide a peculiar yet elicient and substantial carrying and guide structure for the traveling beam and to provide a substantial bearing or support about which the beam may swing on a vertical axis.

With the above and other objects in view as will present themselves to those versed in the art from the disclosure in the following specification the invention consists of the construction, combination, and in details and arrangements of the parts as more par ticularly described hereinafter relative to the embodiment of the invention illustrated in the accompanying drawing, in which:

Figure 1 a side elevation of the walking beam, a portion of its support being in section to indicate one form of structure..

Figure 2 is a plan view of an embodiment of the invention corresponding to that disclosed in Fig. 1.

Figure 3 is a plan view of a modified form of track structure and,

Figure 4 is a side elevation of a portion of the beam and a sectional view of a portion of the modified track structure as shown in Fig. 3.

The present apparatus in its illustrated embodiment comprises a passenger carrying beam like member of suitable form; being in the present case formed of a trussed frame 2 of suitable length and width having a diametrically extending passage-way or aisle 3 providing access to groups of seats 4 on the distal and swinging end of the beam 2. As shown the swinging ends are widened with respect to the passage-way 3 to provide the-desired floor area for the group of seats or chairs 4 which latter may obviously be of any suitable organization or arrangement and may be Xed or movable with respect to the beam 2. The beam is centrally pivoted to oscillate in a vertical plane on a trunnion or shaft 5 which may extend transversely across the beam above or below the Hoor.

lThis trunnion or pivot 5 formed or mounted on the upper part of a tubular journal or bearing member 6 fitting an upright column or post 7 between which journal 6, post 7 may be provided with anti-friction bearings 8 to reduce the resistance of turning forces whereby the beam 2 is swung about its vertical axis. This turning force may be derived from any suitable source and appropriate means and as here shown the bearing or journal sleeve 6 as secured or formed on it, bevel gear 9 engaging a pinion 10 and a jack shaft 11 carrying a reduced gear 12 driven b va pinion of the shaft of a motor 13. This mechanism obviously provides means for imparting rotary movements to the beam.

It is desirable to combine the rotary movement of the beam with vertical oscillations thereof and a feature of the present invention rests in means for accomplishing the desired vertical oscillations. In Fig. 1 the beam has suitably mounted on its underneath structure travelers or rollers 15 appropriately arranged in bearings 16 the rollers being adapted to travel on a. suitable track way in this Fig comprising track 17 having an undulating top surface on which the rollers 15 travel and, as, in this instance, the bearings 16 for the rollers are rigid with the beam it is necessary to arrange the track 17 with a peculiar contour to compensate for* the irregular path or movement of the rollers 15 due to the combination of a vertical movement of the rollers and a rotary movement of the beam carrying the rollers about the axis of the pivot element 7. This peculiar out-line of the track 17 is plainly shown in Fig. 2 wherein the outermost arcs 17* represent the higher levels of the track 17 supporting the upwardly tilted beam to the position shown in dotted lines in Fig. 1, whilst the diametrisoy cally opposite portion of the track 17 is contracted to the position 17" to engage the rollers 15 as they swing to the lowermost and innermost position with respect to the pivot 7. Obviously as many of the undulations as desired may be formed in the track 17 and thereby determine the number of vertical oscillations of the beam during one cycle about its vertical axis; and also the track may be provided with dissimilar cam-like surfaces of unlimited variety.

In Figs. 3 and 4L of the invention a somewhat modified form of the means for oscillating the beam is shown and comprises a track structure including channel irons 20 set back to back and having an undulating top surface but in this case the track structure is circular in plane this being made possible by so mounting the rollers 17 that they can swing with respect to the beam to compensate for the change of horizontal position of their connection to the beam and whilst still engaging the circular track way. The rollers are shown in Fig. 4 as disposed in spaced relation to each other in pairs, one roller on each side of the track structure 2Ol and interposed between the" upper and lower outturned flanges of the channel iron. The rollers are mounted on ayoke 21 straddling the track surface 2O and being pivoted on 22 on a link 23 which in turn is pivoted` at 24 to a suitable supporting bracket as 25 or other convenient place of attachment on the beam. Y

From .this it will be seen that as the beam oscillates the yokes 21'constantlyl travel in acircle while the links 23 swing on thevyokes to compensate for the relative horizontal change of position of their bearings 25 due to the oscillation of the beam.

It will be seen thatby arrangingy the rollers 17 in Fig. 4 underneath ofthe flanges of the rail structure 2O7 the rollers cannot be# come displaced therefrom as they are substantially interlocked against lateral movement. Y

What I desire to claim is:

1. In an amusement apparatus an upright revoluble bearing, a rigid beam-like member revoluble with said bearing and fulcrumed between its ends so as to oscillate vertically, passengerV accommodations at each end of the beam, and apassenger aisle extendingy along the beam, and means yto revolve and oscillate said beam.

2. In an amusement apparatus, a truss beam having passenger accommodations at each end, an upright rotary bearing there-y for, said beam being fulcrumed vtrans-1 versely on the said rotary bearings, a guarded aisle along the beam between the passenger accommodations, and means to re` volve and oscillate said beam.

3. In an amusement'apparatus, an upright revoluble lbearing member, a beam with passenger accommodationsV revoluble with said Abearing and fulcrumed thereon, an undulating circular track provided with lateral ianges, a yoke member astride the` flanges and carrying antifriction bearing de-V vices engaging under the flanges,.anda compensating connection between the yoke member and the beam and means for revolving thebeam. Y

In testimony whereof I aiiixmy signature.

ERNEST KOHLER'.
