Patented Oct. 23,1906,
Application filed November 21, 1905. Serial No. 288,415.
. New Hampshire, have invented certain new and usefu Improvements in Seesaws, of which the following is a description, reference being had to the accompanying drawings and to the figures of reference marked thereon. p
This invention relates to seesaws, and while intended primarily for use as a toy it may also be employed to advantage as an amusement devlce and constructed on a large scale in order to carry passengers.
One of the principal objects of the invention is to provide a power-driven seesaw in which the center of gravity of the seesawarms is arranged below the fulcrum of the latter.
A further object of the invention is to provide a seesaw in which the movable member carries the, propelling mechanism.
, A still further object of the invention'is to provide a seesaw in which the motor mechanism is arranged below the fulcrum-point of the seesaw and is carried by a swinging pendulum that serves in part to regulate the speed of movement of the device.
A still further object of the invention is to provide a device of this character in which a swinging motor element carries an escape ment-wheel, the movement of which is timed by an anchor connected to a stationary portion of theframe and arranged to release the esca ement-wheel only on the completion of a fu l movement. a
A still further object of the invention is to provide a device of this type which may be chea ly constructed and which may be knocked down and packed in small space for shi ment or storage.
ith these and other objects in view the invention consists in the combination of elements hereinafter described, and referred to in the appended claims.
The invention is illustrated in the accom panying drawings, in which Figure 1 is a side elevation of a seesaw constructed in accordance with the invention. Fig. 2. is a transverse sectional view of the same on the line 2 2 of Fig. 1. Fig. 3 is an enlarged sectional perspective view of the upper portion of the frame and the central member of the seesaw, and Fig. 4 is an enlarged detail view of the motor mechanism.
Similar numerals of reference indicate corresponding parts throughout the description.
The main frame of the device comprises a pair of triangular or A frames 10, which are united by transverse plates 11, the latter being provided with small slits to receive tongues 13, projecting from the edges of the plates 10, said tongues being bent out to secure the lates firmly together.
To the plates 10 are fitted inclined legs 14, which preferably are provided withsimple slits for the rece tion of said plates and are readily removable to permit packing in the box or other shipping -receptacle. These legs are held from lateral displacement. on one side by the projecting ends of the plates 11 and in the. opposite side by tongues 16, bent inward from the edges of the plates.
. The two plates are .provided with openings for the reception of a transversely-extending shaft 17, on which is mounted a center iece 18, formed of sheet metal, the side wa ls of which are bent downward and thence inward to form pockets for the reception of the carrying-arms 18. These arms in a toy structure are preferably formed of wood and may be adjusted toward or from the fulcrum-point to obtain a perfect balance. On the outer ends of the arms are arranged dolls or other figures 00, which may be held in place by Wire I straps 20, the central portions of which are seated in end recesses 21 in the arms, while the ends of said straps enter openings 22, formed in the sides of the arms. The center piece is held midway between the plates 10 by suitable filling-blocks or sleeves 23, and secured to and depending from said center piece is a motor-carrying frame 25.
The frame 25 is formed of two spaced pieces of sheet metal, the upper portions of which are provided with side flanges 26 for strengthening purposes, and projecting from the up per ends of these side pieces are tongues 28, which enter slits in the center piece and are bent over to secure the parts firmly together. This structure is further strengthened. by a number of cross bars 30 and spacing-collars 31 between the members of the frame. The frame members 25 are provided with bearingopenings for the reception of a shaft 3,3, to
one endof which is rigidly secured a ratchetwheel 34 and a winding handle 35. The teeth of the wheel are engaged by a pawl 36, which prevents reverse movement of said wheel.
Mounted on the shaft and free to rotate independently thereof is an escapement-wheel 38, which is formed of two die-shaped disks of metal, the central portions of which are dished to form a centrally-disposed circular spring-barrel in which is arranged the motorspring 40, one end of the spring being secured to the shaft and the other to the escapementwheel.
In manufacturing the wheel the metal at one edge of each tooth is twined outward or flanged during the die-shaping of the disks, and as a result the teeth have broad bearingsurfaces for contact with the pallets 39 of the anchor. The anchor is pivoted on an arbor 41, and from its upper face extends an arm 42, the upper end of which has a loose pivotal connection with an arm 43, extending inward from one of the plates 11.
In operation, the spring being wound, it is merely necessary to overcome the inertia of the device, and after this start the spring, acting through the escapement-wheel and anchor, will keep the movable arms and center piece swinging until the spring runs down.
The device may be readily knocked down and packed in a small space for shipment or .storage.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a seesaw, a frame, a swinging member supported thereby, and a spring-motor mechanism carried by said member; substantially as described.
2. In a seesaw, a frame, a swinging member supported thereby, a motor carried by the swinging member, and a connecting means between said motor and frame; substantially as described.
3. In a seesaw, a frame, a swinging member supported thereby, a motor carried by the swinging member and including an escapement mechanism, one member of which is connected to the frame; substantially as described.
4. In a seesaw, a frame, a swinging member supported thereby, a motor carried by the swmging member, an escapement-wheel forming a part of the motor, an anchor engaging the wheel, and means for connecting said anchor to the frame; substantially as described.
' 5. In a seesaw, a frame, a swinging member supported thereby, a motor carried by said swinging member, an escapement-wheel driven by the motor, an anchor mounted on the swinging member and engaging the wheel,
and a rod extending from the anchor and conss4,14c
