DRIVING MECHANISM FOR ROUNDABOUTS.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed. February 23, 1909. Serial No. 479,525.

To all whom it may concern:

citizen of the United States, residing at South Omaha, in the county of Douglas and 1 State of Nebraska, have invented certain new and useful Improvements in Driving Mechanism for Roundabouts, of which the following is a specification.

The present invention relates to improve ments in driving mechanism for roundabouts, particularly as applied to amuse-; ment devices, and in this connection the mechanism may be utilized with advertising or sign exhibiting devices.

In the followingspecification I have illustrated the mechanism as applied to an' amusement device in which a plurality of revoluble turntables are simultaneously rotated, and a vehicle or carriage is caused to pursue a circuitous path around the periphery of these rotating turntables. In its course, the vehicle is guided through a series of curves, loops, etc., beginning at a predetermined starting point, traversing the circle or loop of each rotating member, and returning to a finishing point. In its career the moving vehicle is automatically switched from one turning member to another, without interruption and is guided in a continuous movement from start to finish.

I have illustrated the turntables as of circular construction, but other outlines may be introduced if desired. In the use of circular turntables the vehicle is sometimes caused to pursue a path in the lines of the figure 8, being transferred from one turntable to another by its automatic switch.

One of the special features of the present:

device is the assurance that the vehicle will not depart from its proper path of movement, nor be transferred at an improper point, thus avoiding accidents or collisions,

as it will be understood that a number of' v I .another, as will be more fully described and Be it known that I, ALLEN W. JONES, a

claimed hereinafter.

In the accompanying drawings I have illustrated one example of the physical embodiment of my invention according to the best mode I have so far devised for the practical application of the principles. I have illustrated four turntables, actuated from a master member, but it will be understood that the number may be increased by extending the rotating members in the direction of the four points of the compass to any extent, within the power of the master turning member to rotate.

In the drawings, Figure 1 is a plan View of an amusement device or merry-goround constructed according to my invention. Fig. 2, is a side elevation of the device, the pit and platform being cut away on the line 22 of Fig. 1, and the front turn-table and supporting mechanism being removed. Fig. 3 is an enlarged detail view of a portion of adjoining turntables, showing a vehicle impelling member in the act of transferring from one turntable to another. Fig. 4 is a cross section of Fig. 3 on line 44.' Fig. 5 is a face view of a switch. Fig. 6 is a plan view of one of the impelling members, and Fig. 7 illustrates an impelling member in side elevation, carried by one of the turntables and in the act of being transferred fromone turntable to another, as in Fig. 3.

In adapting my invention as an amusement or pleasure apparatus I usually employ an elevated platform 1 having an entrance 2 thereto and an exit 3 therefrom. The turntables or rotating members 4, 5, 6, 7 8, are preferably flush with the floor of the platform 1 and are supported upon vertical posts or shafts 9, the platform being elevated as desired and supported by posts 10. Each of the turntables is provided with a rack wheel 11, secured at its underside, the teeth of the wheels being in mesh, and the master wheel 11 of the turntable 5, actuates the remaining wheels, as will be understood, imparting to them a reverse motion.

The master wheel is actuated by the pinion 12 which is mounted on an upright shaft 13, and shaft 13 is rotated from the counter shaft 14 through bevel gears 15 and 16. Shaft 14 may be revolved by suitable mechanism not shown. From this construction and arrangement of parts it will be evident that the turntables are rotated from. the master wheel in directions as illustrated by the arrows in Fig. 1. .A series of circular openings 17 are provided iii the platform, in which the tables rotate, the openings being complementary to the tables and neatly surrounding them. U M

A's illuetrated in 1 each turntable is provided with eight metallic bracliets, 18*, preferably countersunk and their tops flush with thelioor of the turntables and platform. These brackets are spaced at regular intervals around th'eperipheri'es of the turntables in positions complementary to each other, so that, as all the turntables revolve in unison due to their connection through the rack wheels, a bracket on each of two turntables is brought into close proximity.

If desired, anumber of vehicles, as designated by the numeral 19, equal to the number of brackets 18 less the number of points of intersection of the various circular tracks, may be employed, but the number may be varied within the aggregate, as will be understood.

The vehicles are operatively connected, each individually and independently, to the rotating turntables, by means of an impeller in the form of a' shoe, or shunt piece.

1 Referring particularly to Figs. 3 4 6 and 7 the. construction and adaptation of the impeller 20 will be more readily understood. A number of these impellers, as great as, or less than the number of brackets 18.1ess the number of points at which they are brought into proximity with each other may be empl'oyed to impel the series of carriages or vehicles. The impellers are situated in the pocket'formed between the'top aortion 21 of the bracket 18. and the upper ace of the rack wheels attached to the underside of the turn tables, the impeller resting on the rack wheel, and movable thereon, in manner to bedescribed. I

Theim'peller 20 is formed .of a triangular shaped frame or base 22 which is provided with perforated bosses or lugs 23 and 24 at the respective front and rear ends in which are secured, respectively, the stud shafts 25 and. 26 ,.by means of set screws 27 The stud shaft 25 h'as journaled thereon an anti-friction roller 28, and a second anti-friction roller 29 is. located at .the rear end of the impeller, being mounted on a pin secured in the plate 30 which is connected rigidly with theibase 22 through the medium of the stud shafts. r t

The brackets 18 are each provided with a pair of semiscircular openings 31 and 32 cut into the edge of thetop flange 21,.to accommodate the rbller':28 and "shaft 26' respectively. "In assembling the parts the .impeller is first placedv upon the exposed face oflthe"ra-ck wheel and then the bracket 18 is bolted thereto, the semi-circular openings accommodating themselves to the roller and shaft.

g The antifriction roller 28 extends upwardly about flush with the surface of the platform and turntables, but the stud shaft 26 is prolonged and extends sufhciently high to afford a pivotal bearing for the vehicle 19 which is attached thereto and adapted to swing lateially thereon. With the parts thus assembled the master wheel is actuated as described, imparting a reverse circular motion to the series (if turntables. The turntables carry the impellers which are held in the pockets as described, and the impellers impel the vehicles forward. A ledge or rib 33 may be placed at the underside of the platform to prevent actual displacement of the impeller, but must be located a sufficient distance from the turntables to allow the passage of the roller 29 and the rear end of the base 22 which projects laterally into the slot '17.

The vehicle is transferred from one turntable to another by means of a stationary switch, indicated at 3st,.there being four switches shown in dotted lines Fig. 1. These switches are essentially metallic wedge shaped pieces secured to the platform and provided with a downwardly projecting portion 85 formed with two inclined faces 36.

The projecting portion 35 is elevated so that I the base 22 may clear it, but is in the path of movement of the antifriction roller 29 at the rear of the impeller and the roller contacts therewith in passing.

An inspection of Fig. 3 will disclose the fact that the impeller illustrated therein has been carried by the rotation of the turntable 5 to its present position and the impeller is being transferred to the turntable 7. The contact of the wheel or roller 29 has swung the impeller, on the shaft 26 as a pivot, and the roller 28 has left the opening 31 of the bracket on turntable 5 and moved into the complementary opening in the bracket on table 7. It being remembered that the two tables are rotating in unison it will be apparent that the impeller will now be carried by the table 7 and the shaft 26 will glide in the direction of the arrow on turntable 7. By reference to Fig. 1 it will be apparent that this switching or transferring movement will take place again at the opposite side of the switch 34 after the vehicle has traversed the outline of the turntable 7 and is returning. The operation of all other switches is similar to that just described.

Now assuming the start to be made at point S, Fig. 1, the vehicle 19 travels around table 4 to the right, is transferred to table 5 and moves around through an arc of ninety degrees; is switched to table 6 and makes the entire loop'thereabout; is switched to table 5 and traverses an arc of ninety degrees, transfers to table 7 and makes a complete turn; is switched again to table 5 and after traversing a curve of ninety degrees thereon is switched to table 8 around which it passes and is transferred to the master table again and traverses the remaining ninety degrees of its outline where it is again shifted to table 4 and returns to the finishing point F; the vehicle is then emptied and brought around to the starting point for another load of passengers, and has made a complete circuit of the turntables.

When it is remembered that the apparatus accommodates a number of vehicles, it will be understood that the carriages travel in a stream or string, and the independent vehicles cross and reoross the path of the moving cars, apparently cutting 011" each other and affording a degree of excitement, but with absolute safety, because of the presence of the positively operating mechanism. The apparatus thus afiords an exhilerating and novel sport which is altogether pleasant and safe.

As before stated, the number of turntables may be increased, within the limits of the ower of the master wheel, and inferentia ly the number of vehicles may be increased accordingly.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1.
