' One object of the present invention is the provision of an improved construction for folding the carriage assembly, seat arrangement, and seat moving features to accommodate smaller and larger riders, improvement for quicker and simpler collapsing or dismounting of other units for a ready out of the way storing, and to facilitate the packing of thedevice.

Another object is the provision of a device of the character described showingsubstantial improvements in the foot rest assembly, in the manual drive, in the wheel assembly and mount ing, in the guard cover for the drive, and in'the locking means for the sectional runway base.

A further object of the present-invention is the provision of a device of the character described having two rider carriages only one of which has a manual drive, the other being a trailer carriage.

These and other improvements embodying the present invention will now be described in some detail, references for this purpose being had to the accompanying drawings, in which:

Figure 1 is a plan view of a complete preferred embodiment of my invention.

Figure 2 is a side elevation of the embodiment of Figure 1.

Figure 3 is a sectional view on the line 3--3 of Figure 1 showing'a drive carriage with the chain guard removed.

Figure 4 is a perspective view of a foot rest assembly.

Figure 5 is a fractional front-view of the carriage folding hinge arrangement.

Figure 6 is a chain spanner front view.

Figure '7 is a perspective view of a swivel wheel with control means.

Figure 7a. is a perspective view of a swivel control bracket.

Figure 8 is a plan view of the carriage assembly as it appears when it is folded.

Figure 9 is a'iractional side view or the folded carriage assembly of Figure 8.

Figure 10 is a detailed side view of dismountviewof a seat rod 4. Claims. (01.272 33) 2. Figure 14 is a perspective view of a pair of lock sleeves for the runway base.

Similar reference characters refer to similar parts throughout the several views.

In the drawing the numerals 20 denote a pair of semi-circular runway sections 20, whose straight edges 23 are adjacent one another and which are connected to each other by any suitable locking means 22. A pair of lock sleeves, 2| (Figure 14) are attached to the peripheral portions of the runway sections 20 adjacent the straight edges 23. These sleeves are U-shaped and have flange portions 24-for embracing portions of the peripheral edges 25 of the runway sections 20. The sleeves 2| are secured to each section 20, and the web portions of the sleeves 2| onone section 20 have tongue portions 26, while the web portions of the sleeves 2| at the other section 20 have groove portions 21. Thus afterthe locking of the-two runway sections 28 by the locking means 22, a tongue portion 26 on one sleeve end will engage a fitting groove portion Zion the other sleeve end, with the result, that the sleeves 2| will hold therunway base against vertical displacement of the two sections .23. To the center of the runway'base there is secured an axle stud plate 30, from'which extends vertically, and to which is stationarily secured, an axle stud 3!, whose upper end is threaded and has screwed thereupon a knurled nut 32. The axle stud 3| is extended through a bearing hole 34 (Figure 8) of a horizontal arm or torque member 33, which is parallel to the top surface of the runway base sections 20. To the ends of the torque member 33 there are hingedly attached two carriages 35, each of which has a neck portion 35a. These carriages are flat. and substantiallyL-shaped, made preferably of plywood, and they normally extended upwardly from and right angularly disposed to the top surface of the torque member 33. The means of hinging of carriages 35 to torque member 33 are shown in Figures 3' and 5. Said hinging means comprise hinge brackets 36 attached to each carriage 35 by bolts'3l and nuts, and a hinge shoe 39, screwed to the torque member 33 at M]; the hinge pin 38 has a head 4| at one end, and a nut at the opposite end; this pin 3 8 extends through holes in the shoe. 39 and the brackets 36, and is secured in that manner by a nut 42. This: arrangement provides hinging means, to fold the carriage 35 parallel to'member 33, making the unit primarily flat. and easy to pack in a narrow space. A connecting rod 45 is hinged with one end to each carriage 35 at 46 and has at its other end a lug shaped portion through which extendsapin that secured to the torque memher 33 at 48 and is provided with a thumb nut 41. This arrangement provides the means for rigid erection, substantially vertical, of the carriages also may be set in this manner slightly inclined to the horizontal, toward the center of torque member 33, as a matter of counteracting the ensuing centrifugal force occurring upon the rider with the circular run of the carriages. This is accomplished by a predetermined length of rod 45.

That edge portion of the carriages 35 which is opposite the hinging means is provided with a plurality of equally spaced notches 53, which are adapted to be engaged by thecarriageseats 5I. Each seat 5| has a back 52, and a side support 53 and is provided with two brace members 54, one of which is to engage one side portion of a carriage 35, at the upper edge of the region of" knurled nuts 58 at their lower ends, serves as'a means to secure each seat 5| to'one of the carriages 35 and for holding the same in place. Since each pair of pins 55 can be inserted into various notches 50, and each pair of rods 56 can be insorted into various notches 59, the seat can'be shifted upon the carriage, providing comfort for a smaller or larger rider. Seat anchors 69 are secured to the carriage 35, one on each side of the carriage, by means of bolts and nuts, as at 6 I. 1 I

In Figures 1, 2, 3, 8 and 9 there are shown two carriages, one with a manual drive, namely the drive carriage, and one without drive, namely the trailer carriage. The left hand carriage in Figures 1 and 2 is th drive carriage.

means comprise two hand cranks 55, secured to an axle 66; a drive sprocket 61 (Figure 13) is secured with its hub to shaft 66. A bushing 68 is affixed to the carriage portion a by its integral flange 68a. Shaft 66 can be rotated in a bushin 58, by means of the cranks 65, manually operated. A chain '69 connects the upper drive 7 sprocket B1 to a lower sprocket III which is secured to one side of a wheel II. This wheel II is rotatable by means of its bearing on an axle I2 which is attached to the carriage 35 by means of screws as at I5. The wheel bracket I4 has a recessed portion, as at I8, a plate-like section I9 which is provided with a hole (not shown) for extending therethrough a bolt I6 of the fork I3. The wheel II, set at the proper angle, and held fixed in place by bolt and nut as at I6, is to follow a circular runway path 11 when the carrousel is in operation.

The rear wheel SI of this drive carriage is of a swivel type, as indicated at 92. The bracket 90 is the same type as bracket I4 and the mounting method of the wheel upon the bracket 90 is like that of the wheel II, namely by a fork 92, bolt and nut 19a.

The drive the sprocket 80 engaging the chain, and the The two wheels of the right hand carriage (Figthe runway path TI, however, they are limited in the range of their swivel action. This limitation is accomplished by interposing a swivel control bracket IIII (Figures 7 and 'I'a) between the upper portion 93 of the swivel wheel 9|, and th under side of the bracket 90. The swivel control bracket I BI is on L-shaped plate (Figure 7a). One of this plate portion has a hole 95 through which is extended the stud 99 of said bracket 90, and the other portion has a clearance 96 between fork members 91 and 98. The bracket IBI, after it has been mounted in place, can be turned about the axle stud 99; thereupon the stud nut is tightened. This enables a proper setting of the wheel 9| to the rear, within the scope of self-aligmnent of radial pathway 11. The clearance portion 96, in coaction with its fork members 91 and 58, will limit theswivel turn of the wheel 9| to the clearance distance of clearance 96. This arrangement will retain the wheel 5 set to the rear, and hold the wheels always close to th middle of the pathway 11, preventing their extending over the runway edge I'Ia (Figure 1). Furthermore, in setting the =work member 98 to hold the wheel 9| controlled'to a minimum clearance to runway l I, it will swivel toward the fork member 91, in the direction of the center of the carrousel, when the forward drive is reversed to backward. In that case a brake action will result from the wheel 9 I, since it is being forced to run out of radial alignment, backward; and the operator will be warned to discontinue an attempt to run the carrousel backward.

To adjust the tension of chain '69, a chain spanner (Figure 6) has a sprocket idling on a bolt, a spacing washer '83, and a screw 84,,threaded into the shoulder portion 82. Washers and 8B, interposed on both sides of the carriage portion 35a, serve to hold the. bolt 81 which is extended through a slot 81 (Figure 3) when said bolt 3 I is tightened by a thumb nut 88. In unscrewing the thumb nut -88, this assembly can be shifted in the slot 8! to either loosen or tighten chain 69;

thumbnut 88 are to be tightened again after an ap pr-opriate setting.

The foot rest assembly (Figure 4) comprises a socket I03 with two lug extensions I04, having screw holes I05, and a pocket I06 with a stop lug I01. This socket I03 is attached to the lower front portion of carriage 35, one on each side. A foot rest I II! with an integral socket plate III, and a foot brace portion H2, is inserted in said pocket I06. The foot rest, when inserted, will extend perpendicularly to the socket. In folding the carriage assembly said foot rest is removed by lifting it out of the socket.

Figure 10 shows a two-handle unit dismountably extended through a hole III] (Figure 8) on the portion 35a of the trailer carriage 35. To a bushing II! are firmly attached two handles H5 and I IS. The bushing I I1 is extended through the hole I Ill, and has a flange -I I8 which is secured to the portion 350; by means of bolts H3. Thumb nuts II 4 preferably are provided on the bolts I I3, so that by unscrewing said thumbnuts the handles can be dismounted.

Figure 12 shows a chain guard II5 with lugs I I6 and with a hole I". The chain guard is attached to the drive carriage 35 by screwing lugs I-I6to the carriage side.

Having thus disclosed the detailed structural description of this invention, the function of the 4 same is similar to that of my co-pending application previously referred to. A rider after placing himself upon the .seat and his feetupon the iootrests H0 can rotate manually the handles of cranks 65 for revolving the drive wheel, which in turn will circulate the carriage seats over the prescribed runway.

This carrousel, arranged for two riders, may be made for a larger number'of riders, according to the constructive principles disclosed in this invention. Likewise, a drive may be arranged jfor in each carriage employed.
