passenger carriers tnereof so that the latter are accessible for occupancy to counter balance the load, w iereby minimum power will be required by an operator for actuating the swing.

; Anoth object of the invention is the provision of a swing of this character wherein he carriers are moved in a prescribed course,

and such movement is effected by a hand power *angeinent operated by the occupants of one of the carriers, the swing being of novel construction to assure easy operation thereof, and also to give pleasure to the passon gers when the swing is in operation.

A further object of the invention is the provision of s "ing of this character wherein the hand power operating arrangement is in convenient reach of the occupants of one of the carriers of the swing so that the same can be successfully operated when the carriers are occupied. V H

A still further object of the invention is the provision of a swing of this character which is simple in construction, reliable and efficient in operation, stron durable, and inexpensive in manufacture.

In the drawings :Figure 1 is a top plan view of a swing constructed in accordance with the invention. Fig. 2 is a vertical transverse sectional view therethrough. Fig. 3 is a front elevation. Fig. l is a fragmentary vertical sectional elevation. Fig. 5 is a perspective view of the hanger frame for one of the carriers. Fig. 6 is a perspective view of one of the cranks.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, 10 designates the base sills, 11 the, spaced vertical uprights, 12 the upper horizontal side rails, 13 the back cross rail, and 14: the braces Specification of Letters Eatent.

which constitute the supporting frame for the swing.

Mounted on the back rail 13 at the top of the frame are spaced bearings 15 in which are pivoted swinging arms or levers 16, to pairs of which are pivoted carrier frames 17 having downwardly curved front ends 18 in which are pivoted hangers 19 supporting boat-shaped passenger carriers 20, each be-- ing provided with seats 21 to be occupied by passengers.

The front uprights 11 of the frame are extended above the latter, and journaled in suitable bearings 22, on the upper ends thereof, is a rotatable shaft 23 to which is fixed a guide pulley 24L, and over this pulley is trained a cable 25. One end of said cable is fixed to one of a plurality of brackets 26, which are secured to the side limbs of the supporting frames 17 and carry pivot shafts 27, on one of which is journaled a guide pulley 28 over which is trained the other end of said cable 25, which is also trained'over a series of guide pulleys 29 mounted at intervals on the frame 17. and fixed to a windlass 30, the journal 31 of which has its suitable bearing in the said frame, and is provided with a hand crank 32 so that the cable can be wound upon and unwound from the said Windlass 30 for the raising and lowering of the passenger carriers 20, thus it being seen that on the lowering of the carriers they will be accessible to passengers.

Journaled in the front uprights 11 of the frame near the top thereof are the stud axles 33 of substantially $-shaped cranks 3a, the

same being loosely connected to the shafts 27 so that on the turning of the said cranks the carrier frames will be moved in a prescribed course for the impelling of the carriers 20 hung therefrom, it being understood of course that the said axle 33 in the center upright 11 is rigidly connected to both of the adjacentcranks 3-1 and that the said cranks are disposed at an angle of one hundred and eighty degrees to each other.

Extending forwardly of the supporting frame at a point elevated above the prescribed course of movement of the frames 17 is a rearwardly inclined crane 35 in the free end of which is journaled a guide pulley 36 having trained thereover a hand impelling cable 37, one end of which is fixed to one of the hangers 19, while the opposite end has connected thereto handles 38 which extend in convenient reach of the occupants of one of the carriers 20 so that the same can be manipulatedfor imparting movement to the swing. a It will be apparent that when both the carriers 20 have been occupied the impelling mechanism therefor will be counterbalanced. so that minimum power will be required by the occupants of one of the carriers for actuating the handles 38 to impel the swing.

When both of the carriers 20 have occupants the handles 38 on the free ends of the impelling cable 37 are gripped and when the carrier at the righthand side of the swing is erates theraising and lowering cable 25, and

as one carrier descends the other is elevated sothat inthis manner the said carriers are accessible passen 'ers.

When the carriers have been occupied the cable 25Iis slaclrened so as not to interfere with the impellingof the swing. The particular contour of the cranks 3f afford resili-.

ency to the carrier frames during impelling action thereof so as to avoid undue shocks and jars incident to the working of the swing. Connected to the carrier 20 at the left hand side of the swing and also to the arm 17 supporting said carrier are brace cables 39 which prevent the swinging of the said carrier. V a

From the foregoing description, taken in connection with the accompanying drawurge, the construction and manner of opera- 7 tlon of the device will be clearly understood,

and therefore a more extended explanation 'hasbeen om1tted.

What is claimed is: I V I V 1. A swing comprismg' a supporting frame, levers. swingingly mounted in the the levers, carriers depending fromthe-free ends of the said carrier frames, cranks rotably mounted in the frame and connected W h the carrier frames, means forimpelling one of the carrier frames for the simultaneous actuation of both ofsaid car ier frames,

and means for raisingandlowering the carrier frames to permitaccess to the carriers. 3. Ina swing,'a supporting ,frame, car- *ier frames movably mounted in the supporting frame, carriers pivotally mounted in the carrier frames, means operable from one of the carriers raising and lowering the carrier frames,

cranks controlling the course of movement of the carrier frames, and levers pivotally connected to-the supportin frame and carrier frames for permitting swinging movement of the latter relative to the movements of the crank. v y
