This invention relates to merry-go-rounds and has for an important object thereof the provision of a device of this character which is propelled by the occupants thereof.

An important object of the invention is to so construct the, device that it may be readily propelled and that rotation thereof may be readily checked by anvoccupant.

A further object of the invention is to improve the construction of merryg'o-rounds of this type, as regards the placement of the necessary supporting seats and racestherefor to permit the seats to actto prevent displacement of the braces, due to the strains to which devices of this character are subjected- A further object of the invention" is the V provision of a device of this character of such construction that bearings about whichfthe device rotates are fully protected from the weather.

A further object of the invention is to provide a device of this character which will be readily and cheaply constructed and which willbe durable and eflicient'in service.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose offillustration is shown a preferred embodiment of my invention and wherein: p

Figure 1 is a plan viewof a merry-goround constructed in accordance with my invention; i Figure 2 is a section on the 1ine2+2 .Of-Figure 1;

Figure 3 1s a section on the line 33 of Figure 2; I v p V Figure 4 is a fragmentary side elevation showing the manner of connecting the seat boards to the arms and braces;

Figure 5 is a plan view of the endsof the seat boards and the plates applied thereto. Referring now more particularly to the drawings, the numeral 10 generally designates a base, at the center of which is arranged a casting 11 having a central upstanding circular flange 12. The body of this casting'is connected with the outer corners of the base by braces 13. Seated at its lower end upon ,is'a vertical shaft'14 anda tube 15 surrounds the lower end of this shaft and fits against and is threaded to the flange 12. The upper end of the tube provides a seat fora rotor base 16 which has an aperture 17 through which the 11' and fitting within bearing 11 n shaft 14 is directed and hasabout this aperture at ts lower "facea flange 18 into which the up- PATENT} OFFICE}:

per end of the tube isthreaded. The rotor base 16 is preferably connected withthe outer ends of. the braces 13 and with the base by braces 19. Upon theupper surface of the rotor base is formed a'circular flange, 20 which is spaced from the edges of the opening l'Z'to provide a'housing for a thrust 'beara 3 'ing 21. I o

' 'The numeral'22 designates a lower rotor casting having an axial opening 23 rotatably receiving the haft 14. The lower end of the hub of this-rotor casting abuts the upper surface of the thrust bearing 21 to be supported thereby and the lower surface of this castmg closely overlies theupper edge of the flange 20 and extends well outwardly there- 'fromQso that the entrance of rain, water and dust to the bearing housing is prevented. The under surface of the rotor casting 22 is formed with an ear 24 to which is secured one end of a brake band 25, the opposite end of which is connected by an adjustable link 26 A to a lever 27 pivotedto the ear. This band embraces the flange 20 of the rotor base. and provides a means, whentightened, for holding the'rotor against rotation withrelation to this base. V i

The lower rotor for engagementwith the lower end of a tube casting has a flange 28 upon 1 its upper surface, which is interiorly threaded 29 surrounding the shaft 14 in spaced relation thereto, this tube having an openingj30 in its'side wall throughfw'hich; lubricant may be introduced to the bearings ofthe lower rotor casting. The upper end of the tube is threaded into a flange31 on the hub, 31 of an I 1 upper rotor casting 32, which hub has an openlng 33 through which the shaft 14 is directed. The upper ends of the bores 23'1and 33 are counterbored, as at 34, for the reception of roller bearings 35. The upper surface of the hub is abutted by awasher 36 held in position upon the upper endof the shaft by a threaded sleeve v37, which provides means for connecting shaft a staff ormast 38. v

Bolted or otherwise secured ends to the lower rotor casting are a plurality of seat supportingarms;3 9;jw hich extend radially; from thecastingfand are approximately horizontally disposed. Secured at their inner ends. to the upper rotorca'sting tojthe upper end ofthe at their inner between in parallel relation tothe seats and,

are arm braces 40, which extend outwardly and downwardly from the upper casting and have their outer end's bolted to'the' associated seat supportingarins adjacent the outer ends thereof, as at l1. Seat boards 42 provided, each of these boards seating atits ends upon plates 43 secured to the ends of the associated seat supporting arms 39. -One ofthese bolts securing the plates in position is preferably the bolt 41" securing'the adjacent extending'through the seat board 4-2. 'In this 1nanner, the seats, seat arms and seat braces can be rigidly secured to one another and there is no tendency to twist betweer'rthe upper and lower castings of the rotor sections.

The braces 40' are further rigidly secured to one. another b'ybars '50 extending thereat such, 21} point that they provide backs for the seats; From one of the arms 49,21; lever 51 is pivot-ally mounted at a point convenient to the adjacent seat boardaLQ and this lever is conne'c'ted' with the lever 27', as at 52 ,t o'provide for operation of the brake". A platform 53 is preferably placed'i'ipon the upper surfaces of the arms 39', so as to preventany accidental contact with the base structure.

It, will beobvious that a construction of this character may be V'ery'readily and cheap- 1y produced and due to 'the'f'a'c't that the beanings thereof are h0us ed, will ive excellent service. While the rener" bearings 3 5 are preferably employed, these maybe omitted if gi l's cdesired that a cheaperstructure be pro- IICQ' i i i Since many; cha-nges are pessible in the con- J structio n' here-interns set for 1 without mate'- muy depar ing from the pirit of the inven- I tion; Iv do notlimit myssir w such specific structure eXcept. as hereinafter claimed.
