Patented Aug. 1 5, 1933 UNITED STATES PATENT ()FFICE DOUBLE horror: SWING A Marie liartinan, SflLOlliS, o. Application rem-nary s; 1932. Serial No. 591,552 1 Claim. j(c1.'f155--e5) The object of invention is to make a "double acting swing, particularly of the type to be A further object is to make a swing'having a combined. foot rest and swing propelling means. In the swing of the type described, it is desirable that when the infant is placed in the swing that it cannot raise itself sufiiciently to fall out of the swing. It is likewise desirable to have a foot rest to support the feet of the infant. The foot rest must be movable in order to prevent the infant from standing on the foot rest andthereby sufficiently elevating its body to attempt to get out of the swing. i It is likewise desirable that the infant be enabled to propel or swing. the swing when it is seated in it and to do this propelling with its legs-1. Whenthe swingispropelled, it

keeps the childsihterest, and when the propels ling is accomplished by means of the childs legs,

1 the movement of the legs provides sufficient exercise for them.

By the means described herein, thepressure of the childs legs, when seated in the swing, against the combined foot rest and propelling f means elevates the swing rearwardly a slight amount. .When the pressure ofthe legs is removed, the swing passes to its normal position and due to the momentum proceeds forwardly in the are of a circle.

cuately forwardly and rearwardly increases, since theswing and its occupant is swinging to the desired extent. The process of propulsion is a natural one and is rapidly learned by thein My device provides further a tray for the reception of the childs toys. The swing may be cheaplyand easily manufactured.

With these and other objects in view, my invention has relation to certain novelfeatures of construction and arrangement of parts as will be hereinafter more fully described, pointed out which Fig. 1 is a plan view of my device. Fig. 2 is aside elevation of my device showing the swing in its normal position at rest. 7 Fig. 3 is a fragmental elevationof a portion of the seat frame and a. portion of the foot rest frame, showing the method of oscillatory juncture between them, when the swing is in the position shown in Fig.2. i Fig. 4 is a front elevation of .my device.

Numeral 7 designates the seat frame, which is formed of a singlepiece of wire or rod, bent-as shown in Fig. land 2. The ends arejoined to- The frame is whichare parallel are bent, as shown at 9. Numeral 10 designates the front of the frame, and, numeral 11 the back of the frame. Numeral 12 designates a rod, parallel to the front of the frame 10 and the back of the frame'll, and secured to the sides 8 at 13, at a point between the front of the frame 10 and the bend at 9 in the sides 8. The rod 12 has its ends bent so, as to hook over the sides 8'.

Numeral 14 designates the fabric seat, which is secured to the back ofjthe frame 11 and to the sides 8 of the frame, in conventional manner, that is by having the edges of the fabric pass around the rods, and having the edges stitched to the body of the fabric seat 14. -The fabric seat 14 extends beyond the bend 9 in the side frames 8 up to the rod 12. v

Numerals 15 designate leg holes in the fabric seat 14. Numerals 16 designate a fabric tray, which is secured to the front of the frame 10 to the sides 8, and to the rod 12, by the same means that the fabric seat 14- was secured to the back of the frame 11 and to the sides 8. The adjoining edgesof the fabric tray 16 and the fabric seat 14 are preferably stitched together. Numeral 17 designates a combined footrest andpropelling means. The foot rest and propelling means consists of the frame 18, which is a rod or wire bent so as to have the outer or lower end 19, and the sides 20. r

Numeral 21 designates a rod having one end the outer or lower end 19. Numeral 22 designates afabric, which is secured to the sides 20, to theouter or lower end 19 and to the rod 21, v The sides 20 of the frame 18 are bent, as shown in Figs. 2 and 5 at 23. Numerals 24 designate loops or eyes formed in the sides 20 above the rod 21. These loops or eyes 24. are formed by bending the sides i'no 20 completely around, that is 360 degrees. The

The ends of the sides 20above the loops or eyes 24, are secured to the front of the frame 10 by looping the ends.

Near the ends of the sides 20 adjacent the joining means or loop for attachment to the front of the frame 10, the sides 20 are bent at right angles inwardly as shown at 26. It will be seen that by these means the combined foot rest and propelling means 17 are pivotally secured to the front of the frame 10 and furthermore that due to the right angle bend in the sides 20 at 26, the movement of the combined foot rest and propellling means 1'7 rotated rearwardly is limited.

Numerals 2'7 designate webbing supports, which are secured at one end in the loops or eyes 24. Obviously there are two such webbing supports as 2'7. Numerals 28 designate webbing supports, which are secured at one end to the back 11 of the frame, near the sides 8. Obviously there are two such webbing supports 28. Ihe free ends of thewebbing supports 27 are secured together by means of the rivets 29, forming the webbing loop 30. Numeral 31 designates a metal hook having one end secured in the webbing loop 30. Obviously there are two such metal hooks 31, employed, one for eachof the webbing loops 30. Numerals 32 designate 2 hook supports, which are secured to the ceiling or door frame, from which the swing is to be suspended. Obviously there are two such hooks 32, and one metallic hook 31 is hooked into one of the hooke 32 and the other is hooked into the other of the hooks 32.

The webbing supports 27 and 28 are of such relative length that the swing will normally hang in the position shown in Fig. 2. The seat frame '7, the fabric seat 14, and the frame 18, are of such relative size that when the child is seated in the fabric seat 14, its feet will come in contact with the combined foot rest and propelling means 17. When the child exerts a pressure on the combined foot rest and propelling means 17 and pushes the foot rest in the direction of the arrow in Fig. 5, the swing will be brought to the position shown in Fig. 5, that is since the webbing supports 27 are secured to the loops or eyes 24, the seat will be elevated to the position shown in Fig. 5. When the pressure on the foot rest and propelling means 17 is removed, by the child ceasing to press on the combined foot rest and propelling means 17, the swing will move to the position shown in Fig. 2, that is, its normal position, but the momentum of the swing with the child occupant is sufficient to swing the child and swing forwardly beyond the normal position. A repetition of this process of applying and relieving pressure on the combined foot rest and propelling means 17, causes the swing to oscillate more and more. The longer this process is continued the greater the amplitude of oscillation. Therefore, by these means, the objects of this device are attained.

What I claim is:

In combination with a swing comprising a horizontally arranged swing frame, to which is secured a fabric seat, a combined foot rest and propelling means comprising a propeller frame rotatively secured to the front end of said swing frame and extending downwardly and rearwardly therefrom, said propeller frame being provided with loops intermediate its ends, swing supports secured to said loops, and swing supports secured to the rear of said swing frame, so that a foot pressure applied to said propeller means will cause said swing and propeller means to move in'an oscillatory manner about a fixed point.
