SWING.

Specification of Letters Patent.

Patented May 21, 191.6.

Application filed January 10, 1917. Serial No. 141,590.

To all whom it may concern:

Be it known that I, J OI-IN S.VWORZALLA, a citizen of the United States, and a resident of Stevens Point, in the county of Portage and State of Wisconsin, have invented a new and Improved Swing, of which the followin is a full, clear, and exact description.

y invention relates to a swing of the type in which the seat is supported on hangers mountedto swing in a foldable frame.

The general object of the invention is to provide a reversible seat formed of variously connected elements carried by the hangers and arranged so that the seat may be positioned at either side of the hangers.

Further objects of the invention are to provide in connection with the reversible seat, novel means to firmly sustain the same in either position; and to provide a construction that will permit of the seat elements being folded within the plane of the hangers so that the swing when folded will occupy the minimum space.

The invention will be particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming apart of this specification in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a perspective view of a swing embodying my invention;

Fig. 2 is a transverse vertical section of the folded swing;

Fig. 3 is a sectional side elevation of the seat and a portion of the hangers;

Fig. 4 is a view similar to Fig. 3 but showin the seat reversed;

ig. 5 is a face view of plates for the seat;

Fig. 6 is a detail in side elevation showing a novel buffer applicable to the legs at the one of the stop bottom thereof to prevent creeping of the form. The side frames or legs are pivotally connected at their upper ends by eye-bolts 14, whereby one side frame may swing within the other to lie in the same plane. Hanger bars 16 are suspended in the supporting frame preferably through the medium of eyes 15 engaging the eye-bolts 14. The hangers 16 may be connected by cross bars 17 near the top.

The numeral 18 indicates the bottom or seat proper and 19 the back thereof. The side bars 20 of the seat 18 are pivotally connected near their front ends with the lower ends of the hangers 16 by pins or bolts 22, and the rear ends of said side bars 20 are I pivotally connected as at 22 with the lower ends of the side posts 21 of the back. Arms 23 are pivotally connected at the forward ends with the hangers 16 above the pivots 22 of the seat 18, the said arms and said seat being disposed between the respective hangers. The rear ends of the arms 23 are pivotally connected with the upper ends of the to receive screws for securing the plate to the adjacent arm 23 to swing with the latter. ,The numeral 27 indicates the pivotal conner sides thereof below and approximately in alinement with the pivots 26. Said stops 28 may be in the form of screws as indicated.

By the described arrangement, the seat 18 and the arms 23 may have a pivotal movement fromone side of the hangers 16 to the other and their movements will carry the back 21. Thus, as shown in Figs. 3 and 4, the seat may be reversed and positioned at either side of the hangers and in either position the seat will be firmly supported by engagement of the lates' 24 with the stops 28. Moreover, the p ates 24 constitute friction elements between the arms 23 and the hangers 16. When the swing is not required for use the legs 10 may be folded one within the other and the hangers 16 Within the plane of the legs. Also, the complete seat may be folded into a vertical position within the plane of the legs as shown in Fig. 2 in which position the friction plates 24'will'sustam the seat.

As is well known the spread legs of the 7 swing constituting the supporting. frame tend to shift under the action of the swing,

there being a shifting force exerted on the forward legs by the forward movement of the swing and a similar ace-011011 the rear legs in the rearward movement of the swing.

To prevent shifting or creeping of the legs I provideresilient buffer blocks 29 preferably of rubber. The under side of each block is beveled or inclined so that one end of the block forms abearing terminal, and a clearance space is presented extending from said end toward the opposite end.

Usually, the beveled surface is produced by.

forming the blocks of reduced thickness at one end, the upper surface'being hor zontal to mate the horizontal under surface of the leg. The blocks are' reversed on the front 7 and back legs so that the bearing terminals thereof of the front legs w'illbe at the front and the bearing terminals of the rear legs will be at the rear. The shocks to'which the front legs are subjected by the swing by a forward movement thereof will'compress the front blocks, increasing the gripping action or the front ends thereof, the

front end thereof to swingto a position at eitherside of the hangers or afposition'betweenfthe' h'angers'and in the plane thereof, a back pivoted at its lowerend to the.

rear end of the said seat, arms pivoted at the front ends thereof to the hangers at the inner faces of the latter above the seat pivots, the said arms being adapted to swing to either side of the hangers or to an intermediate position in the plane of the hangers, the rear ends of said arms being pivoted to the upper end of the said back, saidback being swingable with the seat and arms to either side of the hangers or to a position in the plane of the hangers, stops on the hangers at the; inner surfaces thereof beneath'thepivots of the arms, and plates interp'osed between the outer faces of the arms and: the hangers and swingable with the arms withith'e adjacent pivot s' ofthe arms as axes, the said plates presenting ends proj ecting beyond the upper and lower'surfaces of the arms when the seat is in position for pivots, the said arms being adapted to use, the said projecting ends presenting edges either of which is engageable with thefiXBd stops on the hangers to sustain the seat at either side of the hangers.

2.111 a swing, hangers, means mounting the hangers for swinging movement, a sent between the hangers and pivoted near the front end thereof to swing to a position at either side of the hangers or a position between the hangers and in the plane thereof, a back pivoted at its lower end to the rear end of the said seat, arms pivoted at the front ends thereof to the hangers at the inner faces of the latter above the seat swing to either side of the hangers or to an interi'nediate position in the plane of the hangers, the rear ends of .said arms being pivoted to the upper endof the said back, said back being swingable with the seat and arms toeither side of the hangers or'to a position in the plane of the hangers, fiXed stops on the hangers adjacent to the pivots of the arms, and oppositely disposed stop members on each arm, one of the stop members of each arm being engageable with the fixed stop to sustain the seat positioned at either side of the hangers.

3. In a swing, a support, hangers swingable'on the support, a foldable seat struc tureiincluding a seat, side arms, and a back pivotally connected with the seat and arms, said seat and arms being pivoted to the hangers to be positioned at either side thereof,'a fixed stop on each hanger and a stop rigid with each side arm to turn therewith, each of said stops, when the seat is in position for use, presenting lateral surfaces above and below the adjacentpivot of the arm an'd'disposed toward the fixed stop $0 that either of the said surfaces ofeach stop will engage the adjacent fixed, stop as the seat is positioned at one side or the other ofthe hangers.

4:. In a swing, a support, hangers mounted' to swing on" the support, a seat between the hangers and pivoted near the front end thereto, side arms above the seat and pivoted near the front ends to the hangers, a

back pivotally connected at its lower end with the seat and at its upper end with the side arms, said seat, arms and back being swingable from one side of the hangers to the other, and co-acting stop elements'on the hangers and side arm s engageable with each other when the arms are disposed at either side of the hangers.

5, In a swing, a support, hangers mounted to swing on the support, a seat between the hangers and pivoted near the front end thereto, side arms above the seat and pivoted near the front ends to the hangers, a back pivotally connected at its lower end with the seat and at its upper end with the s1de arms, said seat, arms and back being swingable from one sideof the hangers to the other, a fixed stop on each hanger ben'eath the pivots of the side arms, plates between the side arms and hangers, the adjacent pivots of the arms passing through said plates, and means rigidly fastening the saidplates to the side arms, said plates preside of the hangers, either of said members 10 being adapted to engage the fixed stops on the hangers according to the position of the arms at either side of the hangers.
