SWING.

Specification of Letters Patent.

Patented May 21, 1912.

as that disclosed in my application for Let-' ters Patent, filed September 7, 1909, Serial No. 516,550, in which'an embodiment of my present invention is illustrated and briefly described, and it consists of improved means for starting and stopping a swing of such character.

It further consists of improved means for controlling the speed of such a swing at various points of its operation.

It further consists of improved means for controlling the starting and stopping of the swing.

It further consists of. other novel features of construction all as will be hereinafter fully set fort-h.

The annexed drawings and the following description set forth in detail, one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

Figure 1 represents a side elevation of as much of a swing and its supports as will. illustrate the application of my invention. Fig. 2represents a front elevation of parts of the supporting frame and of the arms for the swing, illustrating my invention applied thereto. Fig. 3 represents an enlarged sectional view of the eccentric device for the swing-arms. Figs. 4 and 5 represent perspective detail views of two elements of the clutch.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, the numerals 1 indicate the inclined props which, together with the top-bar, 2, form the supporting frame of the swing. A rock-shaft, 3, is

journaled to rock in bearings 4, upon the pending from the topbar, and eccentric disks, 12, are keyed upon the ends of said rock-shaft. tric strap, 14, and diverging sockets, 15. The straps fit upon the eccentric disks, and the diverging arms, 16, which support the swing, 17, have their ends, secured in the sockets. The heads are each formed with a radial, tubular neck, 18, preferably between the diverging sockets, and a brakeshoe, 19, fits in the inner end of such neck to frictionally engage the eccentric disk, and has a spring, 20, hearing against it, the tension of which spring is adjusted by a screw, 21, bearing against the other end of the spring and threaded into theneck. An arm, 22, is secured to project from the up per rock-shaft 3, and has a connecting rod, 23, pivotally connected to it, the lower end of which is connected. to an arm, 24, projecting from a clutch-collar, 25, free to turn upon the swing-supporting rock-shaft and secured against longitudinal displacement upon said shaft by a collar, 26, secured upon the same. i

A clutch-sleeve, 27 slides upon a spline,

draw the rod to compress the spring, and

around another pulley, 36, whence it depends at the side of one of the frame props, having an eye, 37, at its end by means of which it may be secured to one of a number of pegs,

Heads, 13, form each an eccen- 42, or similar projections upon the prop.

The ends of the sliding clutch-sleeve are cut away to form semi-annular clutch-lugs, 38 and 39, and the end of the clutch-collar is similarly cut away to form a clutch-lug, 40, to engage the cut-away space in the end of the clutch-sleeve and the space in the collar being engaged by the clutch-lug 38 of the sleeve. The face of the hangeris formed with a semi-annular clutch-lug, 41 to fit with and engage the clutch-lug 39 upon the clutchsleeve.

In practice, the drive-shaft is continuously rotated and the upper rock-shaft rocked thereby. When the clutch-sleeve is shifted by means of the fork, sliding rod and cord toward the clutch-collar upon the rocking arm or, viewing Fig. 2, from right to left, the lugs upon said sleeve and collar will engage and the swing-supporting shaft will be rocked. Owing to the friction between the eccentric disks and the straps and brakes, the arms and the swing will be oscillated and, after the swing has acquired sufiicient momentum, the arms may swing beyond the swing of the eccentrics, owing to the straps turning upon the latter. The friction of the straps and brakes will, however, retard such further swing, so that the reverse movement at the end of each oscillation will not be too abrupt. hen the swing has acquired the desired momentum, the clutch-sleeve is shifted to its middle and disengaged position, and the swing will continue oscillating by its acquired momentum. hen it is desired to stop the swing, the clutch-sleeve is shifted to engage the semi-annular clutchlug upon the bracket, when the rock-shaft will be stopped. As, however, the swingarms are movably suspended by the straps upon the eccentrics, the stopping of the rockshaft will not cause the swing tosuddenly stop, but the straps continue oscillating upon the now rigid disks, and the friction of the former and of their brakes will gently stop the swing. The three pegs upon the inclined prop will admit of the eye of the cord being secured to hold the clutch sleeve in its three operative positions, and the spring upon the sliding rod will throw the sleeve into stop position when the cord is released.

Other modes of applying the principle of my invention may be employed for the mode herein explained. Change may therefore be made as regards the mechanism thus dis closed, provided the principles of construction respectively in the following claims are employed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a device of the character stated, a rock-shaft, means for rocking the same, an eccentric disk upon said shaft, a swing having arms, and a strap around said eccentric disk and having the swing-arms secured to it.

2. In a device of the character stated, a rock-shaft, means for rocking the same, an eccentric disk upon said shaft, a swing having arms, a strap around said eccentric disk and having the swing-arms secured to it, and

ally connected to one of said arms and to the crank-pin, a swing-supporting rock-shaft, a

clutch-collar loose to turn on said latter shaft and having an arm, a eonnecting rod pivotally connected to said arm and to an arm upon the first-recited rock-shaft, a rigid clutch-member, a clutch-sleeve slidable upon and rotatable with the swing-supporting shaft between the clutch-collar and the clutch-member, means for sliding said sleeve, eccentric disks upon the swing-supporting shaft, and swing-supporting straps around said disks.

5. In a device of the character stated, a rock-shaft, a clutch-collar loose to turn on said rock-shaft, means for rocking said col lar, a rigid clutch-member, a clutch-sleeve slidable upon and rotatable with the rockshaft between said clutch-collar and clutchmember to engage either of them, a spring connected to slide the clutch-sleeve against the rigid clutch-member, means for positively sliding the clutch-sleeve in the opposite direction, eccentric disks upon the rockshaft, and swing-supporting straps upon said disks.

6. In a device of the character stated, a rock-shaft, eccentric disks secured upon said shaft, straps upon such disks, a swing suspended from said straps, means for rocking said shaft, means for connecting and disconnecting said rocking means to and from said shaft, and means for positively stopping said shaft.
