MOTOR.

SPECIFICATION forming part of Letters Patent No. 503,878, dated August 22, 1893.

Application iiled January 12, 1893. Serial No. 458,141. (No model.)

To @ZZ whom it may concern:

Be it known that I, FRANK SCHRAM, a citizen of the United States, residing at South Bethlehem, in the county of Northampton and State of Pennsylvania, have invented a new and useful Improvement in Motors for Roundabouts, 0f which the following is a specification.

My invention relates to improvements in motors; and the objects in view are to produce a motor of cheap and simple construction, that is especially designed for use in connection with roundabouts or carrousels employed for the amusement of small children, and which is noiseless in its operation, may be readily wound, and is strong, durable and cheap.

Various other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings: Figure lis a perspective view of a roundabout constructed in accordance with my invention. Fig. 2 is a similar view with the canopy removed. Fig. 3 is an elevation of the motor, the door covering the same being open. Fig. 4 is a vertical transverse section of the motor.

Like numerals of reference indicate like parts in all the views.

1 designates a circular metal base, perforated for the reception of bolts or screws, whereby it may be secured to the door or other support, and into the same there is screwed or otherwise secured, a hollow cylindrical standard 2, which is provided near its upper end With a bearing-collar 3. Mounted for rotation upon the standard 2,and adapted to bear upon the bearing-collar 3, is a casting 4, the same having a general X shape, each of its branches forming rectangular sockets 5, for the reception of the inner ends of the series of sweep-arms 6. v

Journaled in the upper end of the standard 2 is a vertical shaft 7, which carries a small grooved pulley S, and a larger grooved pulley 9 both of which are fixed and adapted to rotate with said shaft. A ratchet-wheel 10, is fixedly mounted upon the shaft 7, immediately above the casting 4, anda pawl 11 is pivoted upon the casting and spring pressed into engagement with the said ratchet wheel.

From each of the sweep-arms 6 there depends a pair of hanger-rods 12, and the same support, at their lowerends, seats or cars 13, of anydesired design,one or more of which may have secured to their under sides a horizontal rod 14, forthe reception of one or more Weights 15, to be employed upon those cars that are unoccupied.

16 designates a vertically-disposed oblong casing, which is mounted at its lower end within a rectangular metal-frame 17, constituting a base, the said base having openings for the reception of screws orbolts, whereby the structure may be secured rigidly to the floor. The casing is situated a convenient distance from the roundabout, and is designed to support and contain the motor through the medium of which said roundabout is operated, and which I Will now proceed to describe in detail.

Within the casing, at the upper end thereof, a transverse shaft 18 is located, and the saine accommodates and loosely supports a series of grooved pulleys 19. A metal frame 20, is located below the series of pulleys 19, and is provided with a depending U-shaped hanger-frame 2l, by which are suspended one or more Weights 22. A horizontal shaft 23, is located in the frame 20, and accommodates a series of loose grooved pulleys 24, corresponding with the pulleys 19, located thereabove. A suspension bail 25, supports the frame 20, through the medium of an unwinding rope 26, which has one end secured thereto and rises therefrom, passes over apulley 27, secured to one of the walls of the casing, and thence laterally over a second pulley 28, which is secured to the wall of the casing. It is then continued down to the series of pulleys 24, under the same, up over a corresponding pulley 19, over the same, and again down under one of the pulleys 24, and so on throughout the series of pulleys, and after reaching the end of the series has its free or advanced end through the casing and secured to the large pulley 9, located on the vertical shaft 7, and which I shall term the unwinding pulley. From the exteriorl of the casing projects a couple of bearing-brackets 29, in which is journaled a crank-shaft 30, a small Windingdrum 31 being located on the shaft between the bearing brackets. A small guide-pulley ICO 32, projects fromthe casing above the bearing-brackets.

33 designates the Winding-rope, one end of which is secured to the small pulley 8, and the opposite end of which is Wound upon the drum 31, said rope having been passed through and` 34 designates acanopyor cover, that is sup- Q ported upon the upper end of the shaft 7, by

a capped pin 35, seated in the upper endy of said shaft. This cover may or may not be used, as preferred;` and, in fact, I may mention at this point, that I do not limit l,my invention to all the precise details of construetion herein set forth and shown by the drawiugs,but hold that I may vary the same Within the skill of those conversant with this class of machines.

The operation of my invention may be briefly stated as follows: By rotating manually the `crank-shaft 30, it will be seen that the rope 33 will be Wound upon the drum of said shaft, and unwound from the small pul-v ley 8. As the rope is unWound from the small pulley 8., the vertical shaft 7,v together with its pulley 9, is rotated, and `inasmuch as the unwinding-ropel 26 is reversely wound upon the pulley 9, to `that of the rope 33 upon the pulley 8, said rope 26 will therefore, be wound upon the pulley 9, and in so doing will elevate the weights 22, to the top of the casing, the rope 26 readily running over the series of' pullleys 19 and 2,4, and being made continually shorter will accomplish this function. During theY Winding the pawl rides loosely over and does not engage lwith the ratchet wheel lO, and thu/s the vapparatus is not operated.

When the crank-shaft is released,or not further operated, the Weights will begin to act,

-and as they descend Aserve to draw 0E or they `may be readily re-elevated by a subse-l quent winding up of the crank-shaft. It w=ill of course be understood that'duri-ng the operation of the motor` the Winding-drum 3l is free to rotate.v

Having described the invention, what I claim is i l. The combination with the vertical shaft `of a roundabout and the4 pulleys, fast upon thesame, of a casing located at one side of 5 said roundabout, a transverse shaft located in thefupper end of the casing, grooved pulleys mounted thereon, a frame located below the shaft, a shaft located in the frame, grooved pulleys mounted thereon and corresponding with those of the uppershaft, weights carried by the frame, an unWinding-rope secured to said Weighted frame and passed alternately over the pulleys of the upper and lower series, and finally connected to one of the pulleys of the roundabout, a drum, and crank-shaft, a rope connected to the same, and having its opposite end connected to and reversely wound upon the second pulley ofthe roundabout, substantially as specified.

2. The combination with the shaft and pulleys of a roundabout, said pulleys diering in size, of a casing located at one side of the roundabout, a shaft transversely disposed in the upper end of the casing, a series of loose 1 g-rooved Vpulleys located on the shaft, atransversely-disposed frame located below said upper shaft and provided with a horizontal shaft, and a depending Weight-supporting frame, a series of grooved pulleys mounted on the' shaft of the frame, a suspension bail connected tothe frame, a ropesecured to the suspension bail and alternately passed about the upper and lowerseries'of pulleys, and iinally secured to the large pulley of the vertical shaft of the roundabout, a pair of bearing-brackets extending from the wall of the casing, a crank-shaft'journaledin the brackets and carrying a drum, and a Winding-rope secured to and Wound upon the drum, and aty its opposite end secured to .the small puel ley of theroundabout and reversely Wound thereupon to that rope connected to thelarge vpulley,'substantially as specified.

r3. The combination Wit-h the rotatable shaft, and the roundaboutcar-ried therebyand large and small pulleyscar-ried by and secured rigidly to the shaft, of a weight motor, a rope operated thereby and leading therefrom to the said large pulleys, a W-iudlass, and a winding rope leading therefrom to the said small pulley and reversely Wound thereon W-ithrelation to the weight-operated ropeupon its pulley, substantially as specified.

4:. The combination with aV roundabout,

comprising a vertical rotating-operating-shaft, `and a pair of pulleys located and secured upon the shaft, of a Weight-operated motor, an unweinding rope operated Vby the motor and secured to one of the pulleys, a Windlass,

and a Winding rope secured at one end to the Windl-ass and at its opposite end to the remaining pulley of the roundabout and Wound thereon reversely to thatrwhich leads from the Weight motor is wound upon the pulley, substantiallyas specified.

I n testimonyv that I claim the foregoing as -my own I have hereto affixed my signature in 1 the presence of tWowit-nesses.
