CHILD S AEROPLANE SWING Application led November 5, 1928. Serial No. 317,284.

Our invention relates to a childs aeroplane swing, and itis an object of the invention to provide a device of this character which simulates an aeroplane in ap- 6 pearance, having a rotatable propeller with means for operating the same, which device may be suspended from -any suitable support, as for example a porch ceiling, tree or the like, all as will be hereinafter more specifically specified and claimed.

Referring to the accompan ing drawings, which are made a part hereo and on which similaireference characters indicate similar parts, Figure l'is a side elevation illustrating one application ofour invention,

Figure 2, an enlarged top plan view of the front end, and i Figure 3, a section on the line 3--3 of Fig. 2.

In the drawings reference character 10 indicates an elongated body having a substantially flat under surface and having its upper surface cut away at 11 to accommodate a childs seat 12, in order to locate the 'center of gravity below the `point of suspension of the body'10. The body is provided with a nose portion 13 which tapers forwardly to a point, and a rounded tail portion 14, the body being supported by chains 15 secured at the front and rear to the body by means of a bolt 16. and an 'screw 17. The bolt 16 is carried in upper end` of the lever 21 in order to dis pose the center. ofgravity below the point of suspensionof the device, it being obvious that if desired in order to increase `the distance of the center of gravity below the point of suspensiona rigid attachving member (not shown) might be fixed at the front or rear of the body 10. 4

"The lever 21 is pivoted on a pin 22 on the body 10, said lever being formed of a pair of spaced members disposed in parallel relation connected by means of pins 23,

24 and 25, the pins 23 forming handles to which the child may hold and the pins 24 and 25 forming foot rests, so that when the child is seated upon the seat 12 astride the body 10 he may exercise his legs and arms in oscillating .the lever 21. p

Across the forward portion of the body adjacent nose 13 isdisposed a plane 18 and across the rear of the body at the tail is f,

disposed a shorter member corresponding to the plane 18, said member giving the appearance of elevators on a conventional aeroplane and serving as a seat for a second child. The members 18 and 19 are formed 00 of pieces of board which may be lheld in place byA any suitable fastening means, as for example screws 20.

A propeller 26is mounted at the forward end of the body 1() upon a shaft or pivot 65 27, and a pulley28 isloosely mounted on said shaft or pivot 27 and is provided with ratchet means for 'engaging and rotating the propeller. At its rear side the propel-4 ler is provided with a circular depression 29 in which the pulley 28 is disposed, and the pulley is provided with a recess 30 in which is mounted a ratchet 31 adapted to engage the propeller and rotate it in one given direction as the pulley is oscillated. Phe lower forward portion of the body 10 has an extension 10 for the reception of screw eyes 32 which form guides for an operatingcable 33 which extends around andfrictionally engages the pulley 28, said operating cable having its extremities e?? attached to a transversely pivoted rocker-bar t e 35 by means of staples or otherfastening members 34. The transverse rocker-bar 35 isconsiderably shorter than the plane 18, S5

and is held in engagement with theunder side of the body 10 by means'of a screw or other fastening element 36. When the rocker-bar 35 is oscillated or rocked to and fro on its pivot 36 the cable 33 will bedrawn -90 back vand forth across the pulley 28 and will oscillate the pulley causing its ratchet 31 to engage the propeller and rotate the sameI continuously in one direction.

Means is provided for operating the rocka er-bar 35 which comprises a ,tog le lever connection with the handle 21, said toggle lever comprising a pair of links .or lever members 37 and 38 connected by means 'of E .a pivot 39 disposed in a subStantiallyve/rti- 1.60

the propelling operation -may be accomplished.

In order to make a noise to represent a motor, a bar 42 having a serrated surface is secured in longitudinal position beneath the body 10 and a resilient metal finger 43 mounted on the handle 21 enga-ges the serrations on the bi1-1242, so that when the handle is oscillated a noise will be produced.

It will be obvious to those skilled in the -art that various changes may be made in our device without departing from the spirit of the invention, and we, therefore, do not limit ourselves to what is shown in the drawings and described in the specification, but only as set forth in the appended claims.

Having thus fully described our said invention, what we claim as new and desire to secure by Letters Patent, is: y

1. An aeroplane swing comprising a elongated body, means for suspending the body from its ends, a handle, a rotary propeller, a pulley adjacent the propeller and aving a ratchet therein adapted to engage the propeller, and a cable connecting said handle and said pulley whereby o eration of the handle will rotate the propel er, substantially as set forth.

2. An `areoplane swing comprising an elongated body, means for supporting the body at each end in a manner to permit it to swing, a handle pivoted in upright position on said body, a propeller rotatably mounted at the front end of the body, a

" pulley associated with the propeller for rotating the same, a member pivoted transversely on the body, a cable having its ends lconnected to the transverse member and extending around and frictionally engaging the pulley for oscillating the same when the transverse member is oscillated, and a lever and link connection between the transverse member and the handle whereby when the handle is oscillated the pro eller will be rotated, substantially as set Orth.

3. An aeroplane swing comprising) an elongated body, means su porting said ody from its extremities an permittin it to swing, a handle extending above an below rotary member when the handles are oscillated, substantially as set forth.

4. An aeroplane swing comprising an elongated body, means for supporting the body at each end in a manner to 4permit it to swing, a. handle pivoted'in upright position on said body, a ropeller rotatably mounted 'at the front en of the bod a pulley associated with the propeller or rotating the same, a member pivoted transversely on the body, a cable having its ends connected to the transverse member and extending around and frictionally engaging the pulley for oscillating the same when the transverse member is oscillated, a leverand link connection between the transverse member and the handle whereby when the handle is oscillated the propeller will be rotated, and means for limiting the oscillatory movement of said handle, substantially as set forth.

5. A device of the class described comprising an elongated body cut out at its central portion to form a relatively narrow sup ort for a seat, a transverse member exten ing across the front of the plane to simulate aeroplanerwingsya handle pivotedin an u right position on the body, a rotatableV mem er mounted on the body and a ratchet connection between the handle and the rotatable member for impartingl continuous rotary movement to the rotar member upon the oscillatory movement of t e handle, substantially as set forth.

In witness whereof, we have hereunto set our hands at North Vernon, Indiana, this 27th day of October, A. D. nineteen hundred and twenty-eight. A
