SWIiNG SPECIFICATION forming part of Letters Patent No. 294,983, dated March 11, 1884. l

Application filed August 18, 1533.

,1 "xi: v Q ZbWaZZ whom it 12710.1; concern.- .Bej iit known thatI, Isaac N. Fonnnsrnn, of the city and county'of Camden, State of New Jersey, have invented a new and useful Improvement in Swings, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure l is a vertical section in line a: 00, Fig. 2, of a swing embodying my invention. Fig. 2 is an end view thereof.

A Similar letters of reference indicate corresponding parts in the two figures.

My invention consists of a swing, which may be engaged by the occupant thereof with mechanism operated by power.

Referring to the drawings, A A represent a suitable frame, on the upper end of which is mounted a horizontally-arranged shaft, B, to which is keyed or otherwisesecured a pin ion, 0.

D represents a toothed segment, which is secured to an oscillating frame, D, the axis whereof is on the base-piece of the frame A, as at a, said segment meshing with the pinion G.

To the frame D is attached one end of a pitman or rod, E, the opposite end being connected with a crank-wheel, F, with which gears a pinion, G, the shafts F F of said wheel and pinion having their bearings on the frame A, the shaft F carrying a pulley or having a crankhandle,-whereby power maybe communicated to the gearing G F, the segment D, and the pinion O, and rocking mo tions imparted to the shaft B.

Depending from and loosely fitted to the shaft .6 is the swing H, and fixed to said shaft is a cylindrical head or pulley, J, which is loosely encircled by a strap, K, formed of metal or other suitable material of an elastic nature, said strap being firmly secured to a casting or piece, K, on the upper portion of the frame of the swing.

L represents a lever, which is pivoted to one end of the strap K, and has also connected with it at another point the other end of said strap K. To said lever is secured a cord or connection, M, the lower end whereof is within convenient reach of the occupant of the swing.

It will be seen that when the shaft F is operated motion in opposite directions is con (No model.)

tinuously imparted to the head J, the swing, however, remaining inactit e, owing to the: freedom of the strap K from the head J.

WVhen the swing is occupied, the occupant depresses the lever L by means of the cord M,

whereby the strap K is clamped tightly on the head J and the motion of the latter is communicated to the swing. XVhen it is desired to stop the swing, the cord M is let go, and the strap K, owing to its expansion, separates from the periphery of the head J, whereby the swing is relieved of the power of said head, and

thus again becomes inactive. The motion of 6 thestrap raises the lever L, and the parts are in position to repeat the operation of clamping or clutching the swing with the head or pulley on the shaft B, it being noticed that the power imparted to the shaft B continues, so that the swing may be set in motion at any time simply by operating the friction or clamping strap and keeping it against the head by means of the cord or connection M and lever L.

If desired,means may be provided for se curing the cord to the swing during the operation of the latter, so as to relieve the occupant of holding the same while clamping the strap and head.

The wheel F has a radial slot, 1), in which is fitted the connecting pin or stud of the pitman or rod E, whereby the latter may be set nearer to or farther from the center of the axis of said wheel F, and the throw of the segment D and consequently of the swing thus 8 5 regulated.

' The'shaft B may be extended and supported so as to be adapted for a number of swings, properly arranged thereon at intervals, and

corresponding numbers of heads or pulleys J,

friction-straps K, and levers L will be employed to cause the operation of the swings, similar to that hereinbefore stated for a single swing, without interfering with each other.

If desired, the pinionC and segmentD may 5 be of the form of frictioirgearing, the object in which case being to impart rotary reciprocating motion to the shaft B.

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

1. A swing hung loosely on a shaft which is adapted to rock or be continuously rotated in reverse directions, in combination with devices for coupling said swing and shaft,whereby the swing maybe set in motion by the operation of said devices and stopped by the release of the same without stopping the rock-v ing shaft, substantially as and for the purpose set forth. I v 1 2. A swing hung loosely on a shaft, and means for clamping the swing'and shaft, in combination with ineans for rotating said shaft in reverse directions, whereby the swing and shaft may be continuously coupled and the swing receive motions in both directions from the shaft, substantially as and for the purpose set forth;

3. A swing, in combination with a shaft from which itdepends, a pinion on said shaft, a toothed segment attached to an oscillating frame and engaging with said pinion, and

mechanism for eoupling'said swing and shaft,

substantially as and for the purpose set forth.

4. A swing hung loosely ona rocking shaft and means for rotating said shaft in reverse directions, in combination with a head or pulley on said shaft, a coupling or clutching device connected with the swing, adapted to engage with said head, and a lever for operating said device, combined and operating substantially as set forth. 7

5. A swing, in combination with a reverselyrotating shaft and means for operating the same, a head onsaid shaft, a friction-strap connected with the swing, freely encircling said head, and a lever for compressing said strap on the head, the lever being connected with both ends of the friction-strap, substantially as and for the purpose set forth. v

o. A swing, rocking shaft, and connected gearing, in combination with a pitman or rod and a crank-wheel, said rod being adj ustably v v connected with vsaid wheel, substantially as and for the purpose set forth.
