HARRY S. MOORE, OF BRIDGETON, NEW JERSEY, ASSIGNOR OF ONE-HALF TO STANTON B. COLE, OF SAME PLACE.

MERRY-GO-ROUND.

SPECIFICATION forming part of Letters Patent No. 504,886, dated September 12, 1893.

Application flled June 22, 1 892.

To aZZ whom it may concern:

Be it known that I, HARRY S. MOORE, a citizen of the United States, residing at Bridgeton, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Merry-Go-Rounds;

andd do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

My invention consists of an improvement in that class of devices known as merry-g0- rounds and contains certain novel features of construction fully shown in the accompanying drawings and described in the specification following. I r

In the drawings Figure 1 is a perspective view of my improved device. Fig. 2 is a plan view of the gearing. Fig. 3 is a partial sectional view of the same. Fig. 4 is a detail View of my preferred form of bearing for the central gear wheel, and Fig. 5 is a sectional View of the ball bearing support for the frame.

One of the principal objects of my invention is to provide a swinging merry-go-round or one having a swinging and circular movement simultaneously.

Referring to the drawings in which similar letters of reference indicate identical parts throughout, A represents the main supporting pole or standard extending upward from a base to which it is rigidly secured, the top of which is provided with a recess mm which is placed a suitable bearing to receive the lower half of a ball, leaving the upper half exposed. A cap B is provided and adapted to lit the upper half of said ball. 0 is a ring of metal or other suitable material to which arerigidly secured the arms D, which may be made jointed if desired so as to occupy the smallest possible space for packing. The outer ends of the arms D may be secured together in any desired manner. From the outer extremities of the arms D to the outer edge of the cap piece B are extended supports rom the arms D there are downwardly extending pieces d which serve to support the circular base E upon which are placed chairs, wooden horses or other analogous devices to be used Serial No. 437,612. (No model.)

by passengers. structed in such a manner as to permit lateral movement to the frame, its central portion being removed for that purpose. A railing F may be placed if desired upon the outer edge of this circular base E for the purpose of increasing the safety of the passengers. Upon the supporting pole A at a point between the circular base E and the ring 0, is revolubly mounted a large gear wheel G. To the upper side of this gear wheel G are attached brackets g at opposite points. In the outer end of this bracket is pivoted the pin g having a divided head or upper end; a like pin g is pivoted in two of the arms D. A link his pivoted in the'upper ends of the pins 9, g so that the motion given to the gear wheel G is communicated to the frame of the machine and the seats or horses carried thereby. This connection while providing for the proper revolution of the main frame admits of any lateral movement which may be communicated thereto. Motion is imparted to the gear wheel G by the spur gear H on a vertical shaft H provided with a beveled gear wheel at its lower extremity which meshes with a second beveled gear wheel mounted on a horizontal rod to which power is applied. Any form of gearing may however be used, and any mode of applying power, as these devices form no part of my invention. Above the gear wheel G upon the pole A there is revolubly mounted as shown in Fig. 4:, a cog wheel I. In Fig. 4 of the drawings, I have shown a'collar interposed between the wheels G and I. This collar may be loose and perform the function of asimple washer or it may be rigidly secured upon the standard and support the wheel I. Above the wheel I a bracket I is rigidly secured to the standard. I prefer to form the bracket integral with and projecting from a collar surrounding the standard, but it may be secured to the standard in any other way. In order to secure the wheel I to the standard and hold it stationary,

The circular base E is con- I a pin '6 movable in an opening in the bracket IOO in a groove in the standard within the wheels G and I as shown in the drawings. Thelower end of the shank may be pivoted to a lever,

said lever extending outwardly to some point easy of access. The pin may be manipulated in any manner however. Meshing with the wheel I and mounted upon the wheel G as shown, on opposite sides thereof, are cog wheelsI' 1. Similar cog wheels I Pare mounted in the same manner on the wheel G near its rim and gear with the wheels I I. To each of the gear wheels 1 1 is rigidly secured a crank arm K K, having pivoted to them or near their outer extremities, rods or their equivalentsL L which are pivotall y connected to two opposite arms D D of the frame of the machine.

In my preferred construction shown in Fig. 2, a spring is interposed at the point of connection of the rods L with the arms D to avoid anyjar which might otherwise occur. It. is obvious that the spring may be located with equally as good effect at the point where the rodLconnects with the crank arm K. Y

In Fig. 2, the wheels I are shownasbeing smaller than the wheel I. This will give the swinging movement at intervals, less than one entire revolution of the wheel- G and the frame. I prefer however, to formthe wheels 1 =of the same size as the wheels I and produce the swinging motion at opposite sides of the machine, or a to and fro motion .at each entire revolution of the wheel G.

The-mode of operation of my improved machine is obvious. Power being applied the. gear wheel H is set in motion which meshing with the large wheel G rotates the frame of the machine upon the ball bearing win the recess at the top of the pole A and upon which bearing the entire frame is supported. As soon as themachine hasacquired sufficient momentum in its circular motion, the pin i is depressed and made to engage the opening in the wheelI and forces the cog wheel Ito remain stationary. The stopping of the wheel I and the continued motion of the wheel G, sets in motion the gear wheels I I, I 1 and consequently the crank arms K K which being secured to themain frame of the machine by the intermediate arms L L give the machine a lateral motion at certain points in its rotation, thus making the frame and base swing simultaneously. The ring 0 is made of sufficient diameter to permit the swinging movement to equal the length of the crank arms K K, and the cap Bis mounted on its bearing in such a manner as shown in the drawings as will permit rotary movement in anydirection.

In using the machine as an ordinary merrygo-round the cog wheels G and I rotate to gether, and in order to insure their unity of rotation, I-provide a pin is bent at right augles as shown, the horizontal portion of which projects from a collar M mounted loosely upon the standard, and adapted to be engaged by the lugs i i provided on the .pin 1'. By this arrangement it will be observed that by raising the pin 1; the vertical part of the pin 70 will be thrust through suitable openings in the wheels G and I and the part '5 of the pin 11 be forced out of connection with the wheel I when thewheels G and I will rotate together. By lowering the pin 2' the part k of the pin 70 will be forced out of engagement with the wheel I and the part i of the pin 11 into engagement with said wheel, holding it in rigid connection with the standard.

Having described my invention, what I claim, and desire to secure by Letters Patent,
