SWING.

Application filed September 4, 1925. Serial No. 54,448.

My invention relates to swings and hasto do more particularly with swings of the character ordinarily employed onporches or lawns and which may be suspended from the ceiling of a porch or from :a frame set in lBl1GQ aICl. i

An object of my invention is tOPIOVIClG an improved structure of the above character and which may be more easily operated by in foot pressure.

Another feature of my invention is a simplified and more positive construction, whereby the swing moves in the direction of the operating force or foot pressure.

For a better understanding of my invention reference is to be had to the accompanying drawings, in which Fig. 1 is aside elevation of a single-seat swing of my invention suspended from a ceils;

Fig. 2 is a perspective view of a removable table;

vFig. 3 is a right end elevation of Fig. 1;

Fig. 4 is a detail view showing the connection between the upper and lower sections of the hangers;

Fig. 5 is a side elevation of theswing of Fig. 1 in the position assumed by the swing when the foot pressure is first applied to start the swing; it v v Fig. 6 is a view showing the double-seat swing; and

Fig. 7- is a perspective view of the frames work and suspending structure alongside the seat of Fig. 6.

Referring now more in detail to the form of my invention as shown in Figs. 1 to 5, I will first refer in general to its operation. That is with the swing in normal position as shown in Fig. 1, the occupant places his feet against the foot boards, and presses forwardly, applying pressure with each for ward movement of the swing, the swing traveling in the direction of the applied force.

Now as to the construction, I provide a seat comprising end rails 10 having seat boards attached thereto and a back 11, preferably rigidly connected to the seat and haw ing arm rests 12 suitably attached,

To the seat frame I attach the propelling and suspending means, consisting of a similar structure at each end of the seat and including intermediately pivoted I suspending members. preferably rigid strips each including an up These suspending members are .per strip13 pivotally suspended at its upper end and a lower striplel: pivotally attached to the'seat frame at an intermediate pointwas 15, the lower end of the lower SGCtlOlT being pivotallyattached to the foot-board frame at 16 and to the upper section 18 at 17.

Therear one of the suspending members is similar to the front one justdescribed.

In Fig-,4: I show a detail view ofthe suspending or hangingmembers and their pivotal connections, the lower section 14: carrying an inneripiece 18 with the seat end rail 10 pivotally supported between thetwo. The section .14 also carries ,at its upper end an outer strip 19 so that the upper suspending member may be pivotallysupported between the two.

I preferably arrange the suspending members so that they are adqustable andswhereloy In the, operation of the swing ofFigs. 1

to 5, and assuming it is suspended and hanging in its normal position as indicated in Fig. 1, the occupant is seated in the rigid seat and places the feet upon the foot-rest 22. The feet are now pushed forward and this throws the parts into the position indicated in Fig. 5, that is with their central pivot moved back of the suspending points 23 at the top. This movement throws the seat forward of its normal position and beyond the center of gravity, so that as soon as the pressure on the foot-board 22 is released the suspension members assume their straight position and the seat starts to move back. As it reaches its rear position the operator again applies forward pressure on the footboards22, thereby again forcing theseat upwardly, this movement being repeated so that in a few pushes the swing is moving back and forth to a suitable degree. When once started it requires but the slightest push to keep it going, each applicationof power or push. being made as the f g is moving forward, so that it might be said that the direction of application of power and the movement of the swing coincide.

To stop the swing it is only necessary to apply the foot pressure in a reverse order, that is as the swing is traveling backward, which brings it to an immediate stop.

In Figs. 6 and 7 I haveshown a doubleseat swing which operates the same as the single-seat swing, that is by power applied in the direction of movement. That is as the swing is moving toward the left, the occupant of the seat at the right pushes forwardly onthe foot-board and the-opposite person does nothing. hen the swing is moving toward the right, the occupant-of the left seat pushes forward.

y In the double-seat swing of Figs. 6 and 7 the side rail 21' for the foot-rest 22 is attached across the two suspending members, which instead of being attached to a single seatare each attached to a separate seat. The two seats are then rigidly connected together by a link 23 and braces 2%, 25 and 26.

What I claimas new and desire to secure by United States Letters Patentis:

1. In a suspended swing of the character described a substantially horizontal rectangular scat frame, an upright back frame secured to the seat, an intermediately pivoted but otherwise rigid suspension member extending from the point of suspension to a point below the seat and pivotally attached to the side of the seat, said suspension member being pivoted between the point of suspension at its upper end and pivotal point of attachment to the seat, and a horizontally maintained foot-rest pivotally connected to the lower end of the suspension member, whereby forward pressure on the foot rest will move the seat in a like direction.

2. A, suspended swing of the character described comprising a substantially horizontal rectangular seat frame, a foot-rest positioned beneath the seat frame, and intermediately pivoted suspension members pivotally connected to each end of the seat frame and to the foot-rest, said suspension members being rigid downwardly from the intermediate pivot, the intermediate pivotal point of said suspension members being above the pivotal connection between the suspension members and seat frame, whereby intermittent application of pressure forwardly upon the foot rest will break the suspending members at said intern'u-rdiate pivotal point and cflect a swinging action of the seat having, a more ment coincident with the direction of pressure.

3. A suspended swing of the character described including a substantially horizontal seat frame, a baclc frame rigidly connected to the seat frame. a foot-rest, and suspension members pivotally connected to the scat frame and to the foot--rest and interlnediaieiy pivot-ally connected above the seat frame connection whereby the intermittent application of pressure forwardly upon the foot-rest will effect a swinging action having a movement coincident with the direction of pressure.

4. In a suspended swing, a seat, a foot-rest below and in front of the seat, having an extension under the seat, a pair of connecting members at each side of the scat pivoted to the seat and to the foot rest extension under the seat, and a pair ofsuspension members pivoted at one end to a suitable overhead support and at the other end to the upper portion of said connecting members above said seat.

In witness whereof, I hereunto subscribe my name this 13th day of April, 1952?.
