Application filed May 9, 1922. Serial N0. 559,509.

Be it known that l, Online lil. llisri'onnn, a citizen oi' the United States, and a resident of the city of l proved Swing, ci which the following` is a full, clear, and exact description.

This invention relates to lawn swings and has particular reference to lawn swings ot the oscillatory type.

Ais an object thev invention contemplates in a lawn swing` of the character ldescribed a swing body, a base, and means for mountingfand supporting` said swing boay upon the base to cause said body to move in an arcuate path upon reciprocations ci the saine whereby to simulate a swinging action.

As a 'further object theinvention contemplates in a lawn swing ot the character set forth, means operableby the occupants oi? theswing for eiiecting reciprocaticns or" the saine.

Furthermore the invention contemplates a lawn swing which is extremely simple in i its/construction, inexpensive to manufacture `and which is highly amusing andattractive in its use and operation.

TWith the above recited and other objects in view, the inventionresides in the novel construction set liorth in the following specification, particularly pointed `out in the appended claims and illustrated in the acconipanyingv drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning ci the terms in which the claims are expressed.

ln the drawings-- lligure 1 is a perspective view ci a lawn swing constructed in accordance with the invention.

Fig. 2 is a longitudinal sectional view therethrough illustrating the body in its normal intermediate position.

llig. 3 is a similar view illustrating thev swing` body in its oscillated position with respect to the supporting base.

Fig. 4L is a transverse sectional view taken approximately on the line M of Fig. 2.

Fig. '5 is a similar view taken approximately on the line 5-5 of Fig. 2.

Fig. 6 is a horizontal sectional view through the top, takenl approximately on the line 6-6 of Fig. 2. f

l ew York, borough ci lrook` lyn, in the county oi Kings and State of New York, have invented a new and lfm-` Reiperring to the drawings by characters of reference, the swing comprises a base A, a swing` body or car B mounted on said base for oscillatory niovement,and a top C de- `f'tach`ably associated with and carried by the swing` body or carB, rlhe base A consists oi a rectangular frame including side rails 10, end rails 11, and intermediate cross rails 12 spaced from the opposite ends of the trame. il pairof arcuate tracks 13 are sup! ported longitudinally within the frame A with one track of each `pair arranged in parallel spaced relation to the side rails and disposed between the end and interme# lfinte rails 1 1 and 12. Preferably the traclrs 13 are supported from blocks 1li secured to the side rails and interposedk inthe entrantA angle iorined at the juncture oit the end and `intermediate railswith the side rails. Suit` able yangular braces or trusses 15 connect the end rails with the side rails at the corners thereof 4for the purpose of strengthening the structure of the base. The swing body or car B embodies a rectangular :trame consisting of side rails 16 and end rails 17 upon which longitudinally spaced transversely disposed seats 18 arer arranged facing one another. longitudinally spaced pairs of arcuate'traclrs 19 are supported 4by bloclts 2O attached to the side rails 1G and the individual tracks or each pair are spaced `from the siderails in parallel relation thereto.

The means for supporting the car or swing bocyB 'troni the base for oscillatory moi/'enient consists of a truck` or platform D `which includes parallel transversely spaced longitudinal stringere 21 trom the opposite `.entremities oi which bea-ring arms`22 depend and within the lower -tree extremities of which bearing arms, transverse shafts 23 are mounted.

prevent disassociation of the truck or plat- A pair ci peripherally; grooved rollers or wheels 24: are carried by form D from the car or swing body and serve as a means for lifting the truck with the car or swing body when the same is lifted from the base, without permitting of the retraction of the tracks 19 from the grooves in the platform wheels 9A. The brace rods 27 further coact with the under side of the stringers 21 to limit the oscillatory movement of the car body B and tiuck orplatform D with respect to each other and witlirespect to the `base A. Preferably the sidel and

end rails

16 and 17 of the frame of the car or swing body are braced by angular corner braces or trusses 28 which brates are connected respectively at their opposite extremities to the side and end rails thereof. The arcuate track rails 13 and obvious that the truck Din its entirety moves in an oscillatorypath with the car or swing body B, but it will be observed that said truck moves at approximatelyone-half the rate of speed ofthe car or swing bodyv and approximately one-half of the distance of said car or swing body. Normally the. truck D and the car or swing body B are disposed in an intermediate position with the upper and lower peripheral edges of the rollers or wheels 2&1 in engagement with the lowermost portion of the lower tracks 13 and thevuppermost portion of the upper tracks 19, said position being assumed dueto gravity. The movement of the swing body is accomplished manually by the occupants of /theseats by pushing the feet against the slats 26 of the truck, while seated on the seats18, which results in relative longitudinal movement of the car body` B with respect to the truck. After `the car or swing bodyl is initially set in motion, the. operation due to momentum effects the partial climbing of the rollers from one elevated end of the lower tracks 13 to the opposite elevated ends thereof.

Thev top or cover C comprises ya. stripfof canvas or other suitable material 30 of rec-- tangular formation having depending side flaps or curtains 31 which is detachably supported from the car body B by means of the B. The top or cover C is maintained inl distended vcondition Athrough thev medium of cross slats 35 which extend diagonally of the strip 30 and which are notched at their opposite extremities as at 36 to coact and engage with the bights 33 of the bails for the purpose of holding the hails in place. A

lf desired a table 38 is adapted to be associated with the car or swing body B in transverse position between the seats 18. The table is associated with the swing body by insertingthe vlower extremities of the pivoted legs 39 in apertures a() in the side rails 16. When not in use the legs 39 are adapted to be folded upwardly and under the table to lie parallel with the bottom thereof.

Iclaim: f 1. A swing embodying a base, a` swing body, means for supporting said body from ythe base. for oscillatory movement with respect thereto, a connection between said means and the 'swing body constituting means for limiting the oscillations of the swing, and means for lifting the supporting means from the` base with the swing body.

2. A swing including a base having up wardly curved arcuate tracks, a platform having wheels supported on said tracks for longitudinal oscillatory movement, a swing body having downwardly curved arcuate tracks coacting with said platform wheels for supporting the swing body therefrom for independent relative movement with and in the same direction as the platform at a higher rateof speed, and means on the car body adapted to coact with the platform for limiting the oscillation of the platform with respect to the car body and of the car body with respect to the base. y .s

`3. A swingincluding a base havinglupwardly curved arcuate tracks, a'platfor'in lhaving wheels supported on said tracks for vlongitudinal oscillatory movement,V a swing body having downwardly curved arcuateA tracks coacting with said platform wheels forpsupporting the swing body therefrom. for independent relative4 movement with and in the same direction as the platform at al higher rate of speed, and meanson the car body adapted to coact with the platform for limiting the oscillation of the platform with respect to the car body and of the car body* with respect to the base, said'means also serving as a means for lifting he platform with the car body from the base.

e. A swing including a base having upwardly curved arcuate tracks, a platform having peripherally grooved supporting wheels engaging said tracks for kmounting the platform from the base for longitudinal oscillatory movement, a swing body having downwardly ycurved arcuate tracks mounted on said platform, wheels for supporting the swing body therefrom for independentrelative oscillatory movement with respect to and in the saine direction as the platform and at a higher rate of speed, and transverse brace bars on said swing body disposed beneath the 5 platform and adapted to coact therewith to constitute means for limiting the oscillation of the platform With respect to the base and the car body with respect to the platform, said bars also constituting` means for lifting the platform with the car body from the base Without permitting the retraction of the arcuate tracks of the body from the peripheral grooves of the platform Wheels.
