SWING.

Speccation of Letters Patent.

Patented Oct. 18, 1921.

Application filed November 28, 1919. Serial No. 341,005.

To all whom it may concern.'

Be it known that I, JosErH F. GUSHMAN, a citizen of the United States, residin in Toledo, county of Lucas, and State of hio, have invented certain new and useful Improvements in Swings, of which the followin@ is a specification.

ly invention has reference more particularly to a swing which is of flexible construction so as to be operated by body pressure against the back thereof, and of collapsible form so that it may be readily folded in a compact condition.

The principal objects of my invention are to provide a swing, the parts of which are held together by the suspending ropes or cables, and having greater flexibility than swings of this character heretofore constructed; to provide a swing wherein the rocking movement is effected by body pressure against the back of the swing acting upon the rear suspending ropes or cables; to provide a construction in which the swinging of the back effects a displacement of the rear suspending ropes without a corresponding displacement of the front ropes; to provide a lateral bracing of the front portions of the swing, and in general, to provide an improved swing of this character which is inexpensive, easier to operate, and more comfortable than those heretofore provided.

On the drawings, Figure 1 is a perspective view of a swing embodying my improvements, and

Fig. 2 a sectional view taken on the line 2 2 of Fig. 1.

Referring to the drawings, the reference numeral 1 indicates the bottom or seat of the swing, which consists of side rails 2, having slats 3 extending therebetween and each rail 2 has a front and rear opening 4 Y and 5 respectively through which the supporting rope or cable 6 is passed. One of these supporting ropes 6 is provided at each side of the swing, and each is supported intermediate of its ends in the usual manner on hooks or hangers at a distance above the swing, and the opposite ends of each rope 6 are inserted down through the apertures 4 and 5 respectively and knotted thereunder as at 7, or otherwise arranged to prevent withdrawal of the ropes from the apertures 4 and 5 and support the swing seat thereon. The back of the swing is constructed in any suitable manner, as for example with top and bottom cross pieces 8 and 9 respectively, with slats 10 therebetween and end strips 11. Each end strip 11 has a post section 12 secured thereto or formed as a part thereof and extending only part way up the seat back as shown, and each post section 12 has a longitudinal opening 13 through which the rear length of the rope 6 is inserted. A similar post section 14 is inserted on the fr ont length of each rope 6, being provided with a longitudinal opening 15 for this purpose, and the two post sections 12l and 14 l are of suitable length to support an arm rest 16 on the upper ends thereof in the desired position. This arm rest has an aperture 17 at the rear end for the rope, and a notch 18 at the inner side of the arm which loosely embraces the side member 11 of the back for retaining the front end of the arm rest 16 inthe proper position with reference to the swing back and seat, and there is an elongated slot 19 at the forward end of each arm through which the front length of the supporting rope 6 is passed.

vWith the construction just described, the parts of the swing are held together by the ropes 6, and because of the termination of the connection of the rear lengths of the ropes with the back portions of the swing just above the tops of the post sections 12 at a point substantially midway between the top and bottom of the seat back, a leverage is affordedV on the rear lengths of the ropes sov so that the rear ropes are more easily displaced by pressure of the swing occupant against the back of the seat, to effect a swinging operation of the swing, and a more resilient or easily yielding' back provided than if the ropes were connected to the top of the back. When the occupant leans back the seat is pressed rearwardly, as for example to the position indicated at 2O in Fig. 2, thereby changing the center of gravity and moving the swing forwardly, and these operations when repeated give successive impulses which efl-ect the desired swinging movement of the swing. As the seat swings rearwardly the seat back oscillates forwardly to the position indicated by dotted lines at 21 in Fig. 2. The end strips 11v of the back are not secured to the arms 16, but are merely held enga-ged in the notches 1S of the arms 16 by reason of the rear lengths of the ropes 6 holding the aperture 17 of the arm substantially in alinement with the opening lof the arms 16 thus avoided.

13 through the post 12. This connection permits relative movement of the arms 16 and end strips 11 in a vertical plane, but on account of the length of the notch 18 and the width of the strip 11 engaged therein,

relative swinging movement in a horizontal,

planey is prevented and lateral displacement The front ends of the arms 16 rest loosely on the posts 14, and the slots 19 through which the front lengths of the ropes are passed are of sufficient length to permit the front ends of the arms 16 to slide forwardly and rearwardly over the tops of the posts 14, thus permitting swinging movement of the back portions of the swing without effecting a corresponding displacement of the front lengths of the ropes 6. As the back moves back to the position shown by the dotted lines at 20 in Fig. 2, the arms 16 move rearwardly therewith and the forward ends of the arms slide over the top of the posts 111 without affecting the position of the forward lengths of the ropes 6, on account of the slots 19, thus enabling the back to be more readily moved and affording an easier support for the back. When the entire swing moves rearwardly, however, the back is moved forwardly, as for example to the position shown at 21, but in so doing the rear end of the slot 19 immediately engages the forward length of the rope and causes a displacement thereof, thus offering a resistance to extreme forward swinging of the seat back and retaining same in a comfortable relative position with respect to the seat 1.

From the foregoing it will be observed that I have provided a swing in which the back is rendered more readily yielding and consequently more comfortable than in swings heretofore constructed, this being accomplished by extending the back up above the point of Aconnection of the rear lengths of the ropes with the rear of the swing, and also by the provision of the slots 19 which enable the back to be easily adjusted rearwardly without effecting a corresponding displacement of the front ropes.

For shipping or storing, the swing may be readily folded in a compact form by lifting the side arms 16 and folding the seat back over the seat 1, and folding the posts 14 under the folded back, after which the arms 16 are laid down on top of the folding swing. While I have shown and described myinvention in a particular form, I am aware that various changes and modifications may be made without departing from the principles of my invention, the scope of which is to be determined by the appended claims.

I claim as my invention: 1'. In a swing, the combination of a seat supported ,by fiexible members at the front and rear, a backhaving a fixed extension at ,each ,end telescoped on the rear flexible supporting members so as to be oscillatably held thereby at the rear edge of the seat, said extensions-being terminated below the middle of the back, and having arm rests loosely supported on the upper ends thereof, and held thereagainst by the forward inclination of the rear flexible members.

2. In a swing, the combination of a seat having flexible supporting members at the front and rear thereof, front and rear posts telescoped on said members above the seat, arm rests having apertures engaging said members, and loosely supported on the upper extremities of the front and rear posts, and a back support interposed'between the rear members and fixed to and extending up above the rear posts. i

3. In a swing, the combination of a seat hay/'ing flexible supporting members at the front and rear thereof, front and rear posts' telescoped on saidmembers above the seat, a back support fixed to and extending up above the rear posts,y arm rests engaging the front and rear postsA and loosely interlocked with end portions of the back support so as to be held thereby against late-ral oscillation.

4. In a swing, the combination of a seat having flexible supporting' members at the front and rear thereof, a back secured to therear members above the seat so as to oscillate at the rear edge of the seat, and arm rests loosely connecting the rear members adjacent the back support with the front members, so as topermit displacement of the rear members without correspondingly displacing thefront members.

5. In a swing, the combination of a seat having flexible supporting members at the front and rear thereof, front and rear posts telescoped on the respective members above the seat, aback support secured to and extending up above the rear posts, arm rests connected with the rear members atthe top of the rear supporting posts and supported at their forward ends on the front posts, said arm rests being provided with slots at their forward ends engaging the front members so as to permit swinging of the` back support and rearward displacement of the rear members ywithout effecting a corresponding` displacement of the front members. n

6. In a swing, the combination of a seat having an arm rest at each end extending from front to rear thereof, a spacer at each end of the varm restinterposed between the seat and arm rest for holding the latter at an elevation above the seat,'a.pair of flexible supporting members at each end of the seat, and connected respectively to the front and rear thereof, and having the spacers and arms engaged thereon and held thereby in superposedrelation, and a backextending @tween the rear'spacers and fixed thereto So vfront and rear members above the respective as to be oscillatably held at the rear edge of the seat by the engagement of the rear spacers with the flexible Supporting members.

7. In a swing, the combination of a seat having flexible supporting members at the front and rear thereof, a back extending between the rear supporting members and oscillatably held thereby at the rear edge of the seat, an arm rest at each end of the seat at an elevation th-ereabove, and extending between the front and rear flexible members, and having an elongated bearing engaging with the end of the back so as to be held thereby against lateral swinging movement with respect to the back.

8. In a swing, the combination of a seat having flexible supporting members at the iront and rear thereof, a back extending between and connected with the rear supporting members so as to be oscillatably held thereby at the rear edge of the seat, and an elevated arm rest at each end of the seat loosely connecting the front and rear supporting members so that the latter may be displaced rearwardly independently of the front supporting members.

9. In a swing, the combination of a seat having a pair of flexible supporting members at the front and rear thereof, a back extending between and connected with the rear supporting members so as to be oscillatably held thereby at the rear edge of the seat, an elevated armrest at each end of the seat having the opposite ends connected respectively with the front and rear supporting members, said connection comprising an elongated slot in the arm rest engaging one of the flexible supporting members so as to permit displacement of one of the supporting members forwardly or'rearwardly without effecting a corresponding displacement of the other supporting member.
