' Specification of Letters Patent.
Patented 13cc. 3, 1907.
Application filed August 9. 1907. Serial No, 387.328.
To all whom it may concern:
Be it known that I, CHARLES C. KEEN,-a citizen of theUnited States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Amusement Device, of which the following is a s ecification in such full and clear terms as Wlll enable those skilled in the art to construct anduse the same.
This invention relates to devices used for the urpose of amusing large numbers of peo ple y means of a device which will give them the sensation of traveling and at the same time providing movable scenery which will make the sensation of traveling more vivid by reason of the fact that the moving scenery gives the effect of motion forward. It is common with such machines to move the platform on which the persons areseated up and down and sidewise, but if too much modifliculty that some persons do not like the device and a moderate motion is therefore the best, where it is intended to have scenery in addition to that fixed to the walls of the structure in which the platform is placed.
In the drawings, in which the same numerals are applied to the same parts throughout, Figure 1 is a vertical longitudinal sectional view of the device, Fig. 2 is a plan view of the same, Fig. 3 is a vertical cross sectional view of the device on the dotted line X, Fig. 1, and Fig. 4 is a detail showing the means used to give the vertical motion and vibration to the platfrom.
The invention is intended to be placed in a tank 1, or it may be placed in an ordinary store room, the sea being imitated by the canvas 2 which is painted a sea green and secured to the walls of the tank or room, and to the sides of the platform or boat 3. The tank is in reality simply a room in which the device is placed, said room being near enough air tight below the canvas to cause the canvas to move up and down in imitation of Waves'as the boat moves up and down, and in order to increase the illusion of motion the platform is provided with antifriction rolls 15 which give it a vibration to increase the illusion of motion.
The boat or platform is provided with a series of seats 4, of which only two are shown in Fig. 3, and it is supported by means of the A frame 5 at the rear, the shaft 6 permitting the boat to be moved in the vertical plane.
At the front the boat is supported by means of the two-cams 13 which are in turn carried by the two A frames 7 in which the shaft 9 is journaled, said shaft carrying the cams 13, a gear wheel 12, and a small pulley 16. The two frames 77 also carry a shaft 8 beloW the shaft 9 on which is a small pinion 11 and the large pulley 10, which latter is driven from the motor M by means of the belt B.
The cams 13 operate in a channel iron 14 in which there is a series of small antifriction rolls 15, said rolls performing two functions, viz; to reduce the friction of the cams against the channel iron and also to give the boat a certain amount of vibration, due to the movement from one roll to another which increases the illusion of motion.
It will be understood that the boat and tank is placed in an inclosed room on the walls of which are various painted scenes, but it is necessary to increase this effect by means of moving scenery. This is done by having an endless curtain, shown in dotted lines at 24, supported by means of two vertically journaled rollers 22 and 23, said rollers being so placed as to support the curtain at an acute angle to the length of the boat. The roller 22 is supported by means of the shaft 19 carried by the step bearing 20 and the side bearing 21, said shaft also having the pulley 18. The shaft 9 has a pulley 16 on one end and around which the rope 17 is passed, said rope driving the roller 22 through its pulley 18. The roller 23 is supported by means of the vertical shaft 25 which is in its turn carried by the step hearing 27, and the side bearing 26.
The operation of the device is as follows: The persons are allowed to go on the boat by means of any suitable bridge which will prevent them from stepping on the canvas 2, and when they are seated the motor is started and the boat begins to pitch up and down at the front end, the air in the tank causing the canvas to rise and fall like the waves at sea, and the curtain begins to move around the rolls 22, 23. The illumination of the apparatus is arranged so that the movement of the curtain is about all that is clearly seen and it gives the effect of movement in a longitudinal direction as well as the actual movement in the vertical plane, the illusion of movement being also heightened by means Having thus described my invention what I claim is as follows, modifications within the scope of the claims being expressly reserved.
1. The combination of a tight compartment, a flexible cover attached to the sides of the compartment, a movable platform to which the cover is attached, and a movable endless curtain placed in front of and at an acute angle with the longitude of the platform.
2. The combination of a tight compartment, a flexible cover secured to the sides of the same, a platform adapted to be moved in a vertical plane and to which the cover is also secured, a movable endless curtain placed in front of the platform and at an acute angle with the longitude of the same, and means to move the platform and curtain.
3. The combination of a tight compartment, a flexible cover secured thereto, a vertically movable platform to which the cover is also secured, two vertically journaled curtain rollers one placed in the front of and the other at the side of-the platform, a curtain carried thereby, and means to move the platform and curtain.
4. The combination of a tight compartment, a flexible cover for the same and attached to the sides thereof, a platform placed near the center of the compartment and to which the cover is secured, a shaft below and near the rear of the platform and on which it is journaled, a shaft having cams which support the platform at its front end, a movable curtain placed at an acute angle with the longitude of the platform, and means to drive the curtain and platform.
5. The combination of a tight compartment, a flexible cover therefor and attached to the sides thereof, a platform placed near the center of the compartment, a shaft adapted to oscillate supporting the platform near the rear thereof, a shaft having two cams which support the platform near the front thereof, a series of antifriction rolls with which said cams come into direct contact whereby the friction of the cams in moving the platform is decreased and a slight vibration imparted to the platform, a vertically placed endless curtain in front of the platform, and means to move the platform and curtain.
6. The combination of a tight compartment, a flexible cover therefor and attached to the sides of the compartment, a platform placed near the center of the compartment, a frame supporting a horizontal shaft to which said platform is secured near the rear thereof, a pair of frames supporting a second horizontal shaft near the front end of the platform, a pair of cams carried thereby and supporting the platform, a vertically placed curtain in front of and at the side of the platform, and means to move the platform and curtain.
7. The combination of a tight compartment, a flexible cover therefor and secured to the sides thereof, a platform carrying a series of seats placed near the center of the compartment, a frame having a horizontal shaft placed near the rear of the platform and below the same, a pair of frames having a horizontal shaft which carries a pair of cams supporting the front end of the platform, a vertical roller placed in front of the platform, a second vertical roller placed at the side of the platform, a curtain carried by said rollers, and means to drive the rollers and platform.
In testimony whereof I have set my hand this 3d day of August A. D. 1907, in the presence of the two subscribed witnesses.
