PATENT OFFICE- FRANKLIN W. KREMER, OF AKRON, OHIO.
SPEOIFIGATI EON forming part of Letters Patent No. 728,246, dated May 19, 1903.
Application filed September 24,1902. Serial No. 124,682. (No model.)
To aZZ whom it may concern:
Be it known that I, FRANKLIN W. KREMER, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and use-.
ful Improvementin Exhibition Apparatus, of which the following is a complete-specifi cation.
My invention has a relation to improvements in that class of devices provided for spectacular exhibitions for, public amusement; and the object of my invention is to produce a new and improved device of the class named.
To the accomplishment of the aforesaid object my invention consistsin the peculiar and novel construction, arrangement, and 'com-- bination of parts hereinafter described and then specifically pointed out in the claims, reference being had to the accompanying drawings, which form a partof this specification. In theaccompanying drawings, in which similar reference-nu merals indicate like parts in the different figures; Figure 1 is an elevation of the fixed portion of niy apparatus with two of the balls, hereinafter described, in connection therewith; and Fig. 2, asection of the track and ball on a greatly-enlarged scale, the ball beingin central section.
Referring to the figures, 1 is a metallic track consisting of parallel tubes 2, united at intervals by cross-rods 3, which are curved to avoid contact with the ball, to be described. One end of this track starts at an elevated platform 4, whence it projects outward and thence is curved to an inclined length to the.
v floor 5, whence it bends spirally witha gradually-decreasing diameter until it terminates erably be twenty-eight inches; but this may be varied with the taste or needs of the user or as experience may determine is safest and most effective. The car to run on this track is a hollow ball 10, having in some part of its periphery an opening by which it may be entered, closed by a door 11, hung by hinges.
where he enters the ball: and closes and secures the door and seatshimself on the seat 17, grasping the upper end of the bars 15 to steady himself. The ball is then pushed onto the inclined portion ofthe track, in the descent of which it acquires such momentum as to" follow the first ascent of the spiral porends of the track, as shown in the drawings,
or by other means to prevent shock to the occupant. The occupant then unlocks thedoor and emerges onto the stage 6, whence he can descend to the floor by a stair.
I do not intend by this description to limit the convolutions of the trackto a tapering spiral, as the convolutions may have the same diameter, but to present this asla preferred form of construction. A 7
Having thus described my invention, what I claim,-and desire to secure by Letters Patof the convolutions of the spiral gradually decreasing toward one end; with landings at either end, and means for communicating an initial velocity to the car, substantially as shown and described.
3. An improved exhibition apparatus consisting of a spiral two-rail track with a substantially horizontal axis of equal gage throughout, with one terminal extended upward at a slight inclination from a perpendicular, and the other terminal in a horizontal plane, said track being arranged to receive a spherical car, substantially as shown and described.
4. An improved exhibition apparatus consisting of a spiral two-rail track of equal gage throughout, with a substantially, horizontal axis, to receive a spherical car, one of the terminals of said track extended at a slight inclination from a perpendicular, with a platform at its upper terminal, and a second platform at its opposite terminal, with means for arresting the momentum of the car at the latter platform, substantially as shown and described. 7
5. An improved exhibition apparatus consisting of a spiral two-rail track of equal gage throughout with a substantially horizontal axis, to receive a spherical car, the convolutions of the spiral gradually decreasing toward one end, the terminal of said track at its greatest diameter extended at a slight inclination from a perpendicular with a platform at its upper terminal, and a landing at its opposite terminal, substantially as shown and described.
6. An improved car for exhibition purposes, consisting of a hollow sphere with a diametric cross-bar having pivotally mounted thereon two arms extended above and below it, with a seat between the oppositely-disposed ends of said arm, and the other ends conformed to form convenient handles for the hands to grasp, and a door by which said car can be entered, substantially as shown and described.
7. The herein-described exhibition apparatus consisting of a spiral two-rail track of even gage throughout, the convolutions of said spiral gradually decreasing in diameter from one end, with an extension at one end slightly'inclined from a perpendicular to a platform; the opposite end terminating at a landing with means for arresting the momentum of the car, in combination with a car consisting of a hollow sphere with a diametric cross bar and two arms pivotally mounted thereon extending above and below said bar, a seat between the oppositely-disposed ends of said bars, the opposite ends of said bars being molded to form convenient handles for the hands, and a door by which said car may be entered, all constructed and arranged substantially as shown and described and for the purpose specified.
In testimony that I claim the above I hereunto set my hand in the presence of two subscribing witnesses.
