MERRY-GO-ROUND.

SPECIFICATION forming part of Letters Patent No. 571,626, dated November 17', 1896.

Application filed November 30,1895. Serial No. 570,597. No model.)

.To @ZZ whom' t may concern.-

ie it known that I, lViLLL-in X. SIMPsoN, of Aurora, in the county of Kane and State of Illinois, have invented a new and useful Improvement in l\:[erryGo-Rounds, of which the following is a full, clear, and exact de scription.

Illy invention relates to an improvement in nierrygo-rounds or carousels and the object of the invention is to combine the motion obtainable in an ordinary nierry-go-round with a seesaw motion, whereby the dizzy sensation experienced by many persons when riding in a nierry-go-round will be obviated by reason of the rotary motion being in a measure int-errupted.

A further object of the invention is to provide a machine of the above description which will be exceedingly simple, durable, and economie in its construction.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a vertical section through the base portion of the machine, the arms adapted to carry the seats or carriages being in side elevation and in two positions. Fig. 2 is a plan view of the machine. Fig. 3 is a horizontal section taken substantially on the line 3 of Fig. l. at is a vertical section through one of the carriages or cars, and Fig. 5 is a side elevation of the same.

In carrying out the invention a framework A is erected, which may be and preferably is in the form of a tower, and in the bottom of the said framework or tower the lower c nd of a vertical shaft l1 is journaled, the upper end of the shaft being journaled in a partition l2, preferably of a spider-like construction, as shown in Fig. 3, the said partition being secured to the framework or tower. The shaft 11 extends some distance beyond the upper end of the tower or framework, and upon the upper face of the partition i2 a bed l is constructed which may be of metahwood, or other material. This bed is of ring-like construction and is preferably of circular contour, fitting at its outer edge to the upper portion of the framework or tower. The bed is provided with a circular opening 1i at its center, exposing a portion of the partition 12, and the upper face of the bed is given an upward inclination or bei/'ehwhereby it is lowest at its inner margin, and in this bed a series of cam grooves or recesses l5 is produced, the recesses or grooves having the saine inclination as the bed. Preferably three of these cam grooves or recesses are used, and they are also preferably of somewhat segmental form and their members, which commence at the inner margin of the bed, are made to join at the upper or outer margin at substantially an acute angle, forming a point o, as shown best in Fig.

A sleeve or hub 1U is secured firmly to the upper end of the shaft 1.1,and from this sleeve or hub a number of arms 17 is made to radiate, the said arms being arranged in pairs. In the drawings two pairs only of such arms are shown, arranged diainetrically opposite each other. Each pair of arms is adapt ed to pivot the inner end of a carrying-arm B, and each carrying-arm preferably consists of a bodybar i8, having a shoe lll secured to its inner end, and the said shoe extends beyond the sides and top and bottom of the bar, and the inner ends of a series of truss-rods 2l are attached to the shoe, the said rods being pref erably located one above, one below, and one at each side of the body-bar 1S, as shown in Figs. l and 2.. These truss-rods are secured directly to the body-bar at their outer ends and are projected from the body-bar between their ends by spokes 20, attached to the said bar.

A pivot-pin is secured to the shoe 19 of each carrying-arm, and these pins serve to pivot the carrying-arms in the hub-arms 1T, as shown best in Fig. 2. The carrying-arms are adapted to balance one another, being 0f equal weight, and at the shoe portion of each carrying-arm a vertical bar 2l is firmly secured, and the lower end of each of the said bars is provided with a friction roller adapted to travel in. the cam grooves or reeesses l5. The bars 24; maybe termed guidebars, since they serve directly to guide the carrying-arms in their vertical or seesaw movements, and the guide-arms 2i of a pair IOO of carrying-arms are pivotally connected at their upper ends above the shaft ll by means of a link or links 2G.

A car C is pivoted at each side of each carrying-arm B at the outer end of the said arm, l(he outer end of each carrying-arm being provided with a weight 22. The cars @,as shown in Fig. 4, are placed, preferably, one slightly below the other, and one or more seats 27 are located in each car; but the arrangement of the cars relative to one another may be varied if found desirable and the two cars may be connected at their outer ends by a partition 2S, as is likewise shown in Fig. 4.

The shaft ll may be rotated in any suitable or approved manner; as, for example, a beveled gear 29 may be secured to the shaft and made to mesh with a like gear 30, located upon a short shaft 3l,the said shaft being provided with a pulley 32 for connection with a motor, and the pulley maybe located within the tower A, as may also the motor.

The arrangement of the guide-bars 24 is such that as the shaft ll is rotated and the rollers 25 of the guide-bars are brought into action the rollers on one of the guide-bars of a pair of carrying-arms will be ascending one nieinber of the cam-groove, while the roller connected with the opposite arm will be descending the member of another cam-groove, and when the ascending roller reaches the apex of the cani-groove in which it is travely ing the opposite roller will be departing from the cam-groove in which it has been traveling, and in. the slight further rotation of the shaft the roller that is still in its cam-groove will commence to descend, thus drawing the opposing roller downward to meet the next groove by reason of the link connection 2G between the guide -bars 24, carrying these rollers. Thus it will be observed that the carrying-arms I3 will be given not only rotary motion, but likewise an up-and-down or seesaw motion at the same time.

Any desired number of carrying-arms may be employed, but the said arms must be in pairs; and if, for example, six are used but three cam-grooves will be necessary, and the connecting-links 2G of each pair of carryingarms will be arranged one above the other.

If in practice it is found desirable, frictionrollers may be placed at the bottom of the guide-arms 24, so as to overcome friction as much as possible.

I'Iaving thus described my invention, I claim as new and desire to secure by Letters Patentl. In a merry-go-round or like machine, a vertically-arranged shaft mounted to rotate, means for driving the same, carrying-arms pivoted in supports connected with the said shaft, the said arms being arranged in pairs, a bed surrounding the shaft and having its upper surface inclined or beveled and provided with cam grooves or recesses having substantially the saine inclination as the bed, a guide-bar secured to each carrying-arm near itspivotpoint and adapted to travel at its lower end in the inclined camegrooves or the bed, a connection between the guide-bars of each pair of carrying-arms, and cars pivotally connected with the outer ends of said carryingvarms, as and for the purpose specified.
