GEAR FOR MERRY-GO-ROUNDS.

which the following is a full, clear, and exact description.

The invention relates to merry-go-rounds in which crank-shafts are employed foriniparting an up-and-down movement to the horses or hther seats.

The object of the invention is to provide a new and improved gear for merry-go-rounds arranged to accommodate any desired number of crank-shafts and to drive the same directly and at the same speed from the mainv gear-wheel, thus obviating all compounding of the gear and rendering the merry-go-round simpler and more durable in construction and more effective in operation.

The invention consists of novel features and parts and'combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying (.lrawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the improvement. Fig. '2 is an enlarged plan view of part of the same. Fig. 3 is a cross section of the same on the line 3 3 of Fig. 2. Fig. 4 is'a section on the line 4 4 of Fig. 5. Fig. 5 is an end view of the head of one of the seat-supports in position on the crank-arm of the crank-sl'iaft, the crank-shaft being shown in section; and Fig. 6 is a section on the line 6 6 of Fig. 2.

On the central post A of the merr -goround is mounted. to turn a frame B, provided with the usual pin or lantern wheel C, in which meshes a pinion D, secured on the ve'rtically-disposed shaft. E, connected with and driven by an engine or'other motor for rotating the frame B in the usual manner. On the frame B are ar anged radially-disposed crank-shaits F, having at or near their outer ends the usual cranks F, on which are hung supports G for the horses or etherseats H. On the inner ends of the crank-shafts F are secured bevel-pinions I in mesh with a large bevel gear-wheel J, secured at its hub to the central post A, so that when the frame B Specification of Letters Patent. Application filed April ll),

l is turned the crank-shafts Fare carried bodily lalong and are rotated by their pinions I ines-hii'ig with the fixed gear-wheel'J. The rotary motion of the crank-shafts F causes seats H.

In order to permit of driving each crankshaft F directly from the fixed bevel gear wheel -J without the use of intermediate cumbersome gearing, it is necessary to make the face of the fixed bevel gear-wheel J sutliciently wide to accommodate adjacentpinions 1, the latter being arranged in staggered form and overlap )ing each other more or less, according to t e number of crank-shafts F employed.

.It is understood that for large-sized merry; go-rounds a large number of radial crankarnis F are necessary, and in order to drive all these crank-shafts directly from the gearwheel J by the pinion I it is necessary to overlap adjacent pinions considerably more than is required for sr-ialler-sized merry-gorounds having a less number 'of cranleslialts F. The inneri'nost pinions l are less in diameter than the outermost pinions to insure a proper meshing of the pinions with the fixed gear-wheel J and to maintain a uniform speed of all the crank-shafts F. Thus bv largest pitch diameter of an innermostpinion I is less than the smallest pitch diameter of the adjacent outermost pinion I but the same ratio of speed between the :tixed gear-, wheel J and the pinions I is maintained.

Any one of the crank-shafts F can be thrown out of action, and for this purpose the inner end of each crank-shaft is mount-ed to turn in an eccentric bushing K, journaled in a suitable bearing B, secured to the frame B, and on the said bushing K is secured an arm or handle K, adapted to be taken hold of by the operator to swing the same from a normal position over to a diametrically op 0- site position, so as to cause the bushing I to turn in its bearing B, and consequently lift the inner end of the crank-shaft F to move the corresponding pinion I out of mesh with the large gear-wheel J. i

On the crank-shaft F, adjacentto the bearing B, is secured a toothed wheel L, adapted to move in engagement with a locking-piir L, secured to or forming part of the bearing B. Normally the toothed wheel L is out of engagement with the locking-pin L-that is, at the time the pinion I is in mesh with the an up-and-donn or rocking movement of the" reference to Fig. 32 it willbe seen that tlie gear-wheel J but when the shaft F is raised by the action of the bushing K, as above explained, then the toothed gear-wheel L moves. 1n engagement with the locking-pin L, and consequently the crank-shaft F is locked against turning at the tinte its pinion I is out of mesh with the gear-wheel J.

Bf? thearrangentent described the crankshaft F can be rendered inactive whenever it is desired to do so, sot-hat the seats carried by the crank-shaft do not move up and down, but travel around with the frame B.v

If desired, every other crank-shaft may be thrown out of action, so that an up-anddown moving seat is followed bf a stationary seat and the latterfollowed b an up-anddown moving seat, and so on throughout the series. I v

In orderto permit a convenient connecting and disconnecting of the supports G withor from their crank-arni's F, the following device is provided, special reference being had to Figs. 4 and 5: The head G of a support G is in the shape of' a fork, provided at its 2 forked members with inwardly-extending lugsG adapted to engage recesses N,f01"l27l in the top of a box N, through which extends the crank arrn'F of a crank-shaft F. The box N is preferably made in two parts, hinged together at one endand having their opposite ends fastened together by a bolt, screw, ,or like means, as plainl indicated in Fig. 5. A button 0 is fulcrumed on top of the box N andisadapted to swing with its free ends -over the lugs G so as to hold the same against accidental displace-latent in the recesses N of the box N. f

On the crank-shaft F, *ithin the box N, is secured or formed a collar F fitting a correspondinglp shaped recess in the upper part of the box N, so as to hold the latter from sliding on the crank-arm F in the direction of the length of the crankeshaft F. The lower portion of-t-he box N is made hollow to form a well for the lubricant, which by the construction described is not liable to work 'ou of the box and drop down on the occupant of a seat. ."Whenever it is desired to disengage a sun- 5 p0 Gi'rom its corresponding crank-arm F, th it is only necessary for the operator to s iviilg the button 0 out of engagement with the lugs G and then the o1: crater, by lifting the support G a short distance, causes the disengagement of the lugs G from the recesses N, and then the support G can be dropped downward to disengage the head G completely from the crank-shaft F, as the distance between the inner ends of the lugs G is somewhatmore than the diameter of.the ank-shaft F. If it is desired to disconnect 2e box X from the crank-arm F, it. is only. pneces'sary to open -removal of the crank-arm.

From the foregoing it will'be seen that each the box for the convenient tn scenes crank-shaft F is directly driven from the up and down, it being understood that such inactive crankshaft is locked against turnmg movement by the device above described,

. and shown in the drawings.

It is understood that instead of having a single fixed gear-wheel J of a Wideface to accommodate two adjacent pinions I at the outer and inner face portions the main gearwhe'el J may be arranged in two or more concentric sect-ions; but in either case the same speed of the crank-shafts F is maintained.
