prises an upwardly United States Patent 3,155,388 IVfERRY-GO-ROUND Orville E. Walden, Box 46, Nilwood, Ill. Filed Nov. 16, 1962, Ser. No. 233,173 20 Claims. ((31. 272-33) This invention relates to a novel rider-operated merrygo-round.
The primary object of the invention is the provision of a safe, etiicient, simple, and practical device of the kind indicated, which is devised to be made in different sizes, for home and playground use, and which affords children exercise and amusement greater than is obtainable from motor-driven devices of this kind.
Another object of the invention is the provision of a device of the character indicated above, which features resiliently mounted horses, whose upward and downward movements, produced by actions of the riders, operates ratchet and gear means for rotating the wheel of the device.
A further object of the invention is the provision, in a device of the character indicated above, of ratchet means for preventing retrograde rotation of the wheel, and of releasable clutch means for connecting and disconnecting the gear means, whereby the wheel can be disconnected from the gear means, so that operation of the ratchet means by children bouncing on the horses will not produce rotation of the wheel, when such is not desired.
Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.
In the drawings:
FIGURE 1 is a top plan view of a device of the present invention;
FIGURE 2 is a side elevation thereof, some of the horses being removed;
FIGURE 3- is an enlarged fragmentary vertical transverse section taken on the line 33 of FIGURE 2;
FIGURE 4 is a horizontal section taken on the line 4-4 of FIGURE 3;
FIGURE 5 is a fragmentary vertical section taken on the line 5-5 of FIGURE 4;
FIGURE 6 is a fragmentary vertical section taken on the line 6-6 of FIGURE 3;
FIGURES 7 through 10 are views like FIGURE 6, showing difierent forms of ratchet drives and flexible horse supports; and
FIGURE 11 is a perspective view of a further form of flexible horse support.
Referring in detail to the drawings, wherein like and related numerals designate like and related parts throughout the several views, and first to FIGURES 1 through 6, the device therein illustrated comprises a horizontal support 14, which can be a floor or a ground surface, upon which is fixedly mounted a base 16 having a reduced diameter upstanding externally threaded pedestal 18 thereon, on which is threaded a nut 20. A bearing ring 22 surrounds the pedestal 18 and bears upon the upper side of the nut 26. The upper surface of the bearing ring 22 is formed with laterally spaced chordal grooves 21, in which the horizontal arms 23 of a fork 25 slide. The arms 23 have shallow terminal portions 27 at whose inward ends are upwardly angled ramps 29 which merge into the upper surfaces of deep portions 31. The arms 23 have upstanding stops 33, at the inner ends of the deep portions 31. a
A closed vertical cylindrical gear housing 28 comopeningcuphaped lower section 26 having a bottom wall 24 which bears upon the fork 25,
normally resting upon the deep portions 31 of the fork arms 23, as shown in FIGURE 3. The lower housing section 26 has an upstanding sidewall 30 on the exterior of which is fixed an upwardly facing ratchet ring 32, with which is engaged a ratchet pawl 34 mounted on the lower part of the sidewall 36 of the inverted cup-shaped upper section 38 of the housing 28. The lower section of the housing 28 is slidably splined to the pedestal 18, as indicated at 19.
Whenever it is desired to disengage the ratchet ring 32 from the ratchet pawl 34 and the drive pinion 122 from a crown gear 82, to enable the upper gear housing section 36 to run free with respect to the lower housing section 26-, the lower housing section 26 can be lowered on the pedestal 18, to which it is keyed, as indicated at 19, by moving the fork 25, in an outward direction, so as to cause the deep portions 31 of the fork arms 23 to move out from under the lower housing section 26 and let the housing section 26 down upon the shallow terminal portions 27 of the arms 23. For this purpose, a horizontal push-pull rod 37 is provided, which is swivelly connected, at its inner end, as indicated at 39, to the outer end of the fork 25, and is pivoted, at its outer end, as indicated at 41, to the lower end of an operating lever 43. The lever 43 is pivoted, intermediate its ends, as indicated at 45, on the upper end of a stand 47, which rests upon the support 14, at the outer edge of the wheel 76 of the device.
The fork 25 is moved inwardly, by operating the lever 43, when it is desired to elevate the lower bearing housing section 26 for reen-gaging the ratchet ring 32 with the ratchet pawl 34, so that the ramps 29 engage the near side of the lower section 26 and elevate the same sufficiently to enable the deep fork arm portions 31 to move supportably under the lower section 26. The stops 33 engage the near side of the lower section 26 and prevent the fork from being moved too far inwardly.
The upper housing section 38 has a top wall 40 which is provided with a central opening 42, in which is suitably fixed the lower end of a vertically elongated tubular spindle housing 44, which spacedly encloses a spindle 46 which is fixed to and rises from the upper end of the pedestal 18. The spindle 46 is smaller in diameter than the pedestal 18 and therewith defines an annular shoulder 48, which is outwardly angled and is opposed to and parallel with an inwardly angled annular shoulder 50, in the lower end of the spindle housing 44. Balls 52 or other suitable anti-friction bearings are seatably confined in grooves 54 and 56, in the shoulders 48 and 5t), respectively.
The spindle 46 has a reduced upper end 53,,defining a shoulder 60, and an annular anti-friction bearing 62 is circumposed on the upper end 58 and rests upon the shoulder 60, and has its outer race 64 securably seated in a groove 66, within the upper end of the spindle housing 44. A nut 61 is threaded on the upper end 58 and holds the bearing 62 down in place.
The lower part of the spindle housing 44 has externally fixed thereon an annular horizontal plate 68 which rests upon and is fixed, as indicated at 72, to the top wall 40 of the upper section 38 of the gear housing 28. Diagonal brace bars 74 are suitably afiixed to the upper part of the spindle housing 44 and the plate 68, at the outer edge thereof. The plate 63 constitutes a part of a horizontal wheel 76, which includes an outer horizontal ring 78, which is fixed, as indicated at 80, at its inner edge, to the plate 68.
The gear housing 28 encloses, a suitable lubricant being contained therein, an upwardly facing crown gear 82 which has a central opening 34 receiving and splined to the pedestal'18. The crown gear 82'has upwardly facing Patented Nov. 3, 1964- bevel gear teeth 86, on its peripheral edge and which is fixed, at its lower end, to the lower housing section 26.
Horizontal radial, circumferentially spaced drive shafts 118 are. spaced beneath the wheel 76 and are supported, at their outer ends, in brackets 120 fixed to and extending downwardly from the Wheel ring 78, and are journaled, at their inner ends in bearings 124, in the side wall 36 of the upper housing section 38. The shafts 113 have pinions 122, on their inner ends, which are in mesh with the teeth 85 of the crown gear 32.
The drive shafts 118 are driven by means of ratchet wheels 126 fixed thereon, at the inner sides of the brackets 120, and engaged by ratchet pawlslZS, pivoted on the adjacent sides of pawl wheels 13%, which are journaled on the drive shafts, between the brackets 120 and the ratchet wheels 1126. The pawl wheels 136 have tangential levers 131 fixed thereto, as shown in FIGURE 6, which extend to and are pivoted, as indicated at 132, to the lower ends of vertical bars 134, which work freely through openings 136, provided in the wheel ring. The bars 134 are pivoted, at their upper ends, as indicated at 133, to brackets 14%, which are suitably fixed to the undersides of the bodies 142 of horses 144 or other animal figures. When the horses 144 are depressed by children riding thereon, the bars 134 move downwardly and rotate the pawl wheels 13%, in a direction to engage the ratchet pawls 128 with the ratchet wheels 12 6 and rotate the drive shafts 118, for rotating the wheel 76. When thereafter the bars 134 rise, the pawls 128 ratchet over the ratchet wheels 12-6 and do not produce rotation of the drive shafts.
The horses 144 are mounted upon the wheel ring 78, by means of resilient spring mountings 146, which comprise reclining U-shaped fiat springs, have lower arms 148 suitably fixed upon the wheel ring 78, in chordal position, and dual laterally spaced upper horizontal arms The upper arms 150, as shown in FIGURE 3, are disposed at opposite sides of and are spaced from the brackets 140, and are individually fixed, as indicated at 152, to the undersides of the bodies of the horses 144. This arrangement provides for limited lateral movements of the horses 144, relative to the wheel 76, as well as up and downmovements relative thereto, as produced by children riding upon the horses.
It will be understood from the foregoing that, upward and downward movements of the horses 144 produce rotation of the wheel 76, through rotation of the shafts 113, the pinions 122, and the crown gear 82.
Another form of ratchet mechanism is shown in FIG- URE 10, wherein the vertical bar 131 i works in a guide way 154 secured beneath the wheel ring, and has a rack 156 engaged with teeth 158 on the pawl wheel 126*, the upper end of the bar being pivoted, at 133, to the bracket 149 secured to the body of a horse 144.
FIGURE 7 shows a further form of ratchet mechanism and spring mounting for the horses 144, wherein a horizontal rock lever 16%) is pivoted, at one end, at 161, to the upper end of the vertical bar 134 and is pivotally sup: ported, between its ends, at 15.3, on an upstanding bracket 162, on a base plate 164, suitably fixed upon the wheel ring 78, beneath the body of a horse 144. The horse is fixed upon the lever 160. Rocking movements of the rock lever 16th are controlled by a first coil spring 166, stretched between a lower part of the bracket 162 and a part of the rock lever between the bracket and the vertical bar 134', and .by a second spring 163, on the opposite side of the bracket 162. The second spring 158 is stretched between the base plate 164 and the lower end of a vertical adjusting screw 179, which is threaded through the free end of the rock lever 160, and has thereon a lock nut 1'72, adapted to bear against the rock lever, for maintaining a tension adjustment of the springs, to accommodate horse riders of different weights.
FIGURE 8 shows an alternative form of spring mounting 146 for a horse 144-, which comprises an elongated S-curved leaf spring 174, occupying a declining position, relative to the wheel ring 78. The spring 174 has a lower arm 176 passing freely through an opening 178, provided in the wheel ring and extending below the ring, where it is traversed, at its free end by a vertical tension adjusting bolt 18%), which works upwardly through the wheel ring 78 and has a collar 182 fixed thereon above the ring 78. A look nut 184 on the bolt 180 engages the underside of the spring arm 17 6. A bracket 1S6, fixed on the upper side of the Wheel ring 78, has an arm 188 overlying the bolt 180, and a coil spring 19%), circumposed on the bolt, is compressed between the arm 188 and the collar 182. The spring 174 has an upper arm 19.2, spaced above the wheel ring '78, which is adapted to be fixed to the underside of the body of a horse 144.
FIGURE 9 shows a still further form of spring mounting 146 for a horse 144, which comprises an upstanding bracket 1% having a transverse shaft 1% journaled therethrough, having fixed thereon a pendant arm 1%. The bracket 19 has spaced ears 2% through which adjustable stop screws 20?. are threaded inwardly toward the opposite sides of the arm 198 for adjusting the rotary portion of the shaft 1%, in order to increase or decrease the tension of a spiral spring 2414, which surrounds the shaft 196, and has its inner end fixed thereto, as indicated at 2%. The outer end of the spring 204 is extended tangentially therefrom to provide a horizontal arm 2E8, adapted to be secured to the underside of the body of a horse A still further form of spring mounting is shown in FIGURE 11, which comprises an open horizontal ring 224, adapted to be secured upon the upper surface of the wheel ring 73, from whose spaced ends reclining J-shaped springs 226 extend and reach across the ring 224, and have straight horizontal portions 228 which are adapted to be secured to the underside of the body of a horse 144.
