Application led September 6, 192'?. `Serial No. 217,738.

llhis invention relates to swings, and more particularly to a swing1 of simple construcf tion and portable nature, designed to afford healthful body developing` exercise, as well as amusement and pleasure.

itin` object of the invention is to provide a frame construction dispensing1 with the use of bolts and other-fastening devices and pro` vidinp,` a lmoclodown7 construction which may be easily assembled and which, when assembled provides a rigidlyinterloclied frame. in accordance with this object, a feature of the invention consists of a frame having side and cross members with uprights at their junctions, said members and uprights beingl interjoined by mortise and tenen. Addr tionally, and as a further feature, a wedgingj;l interlock is provided for a member so joined.

fl. further object ofthe invention is to provide a suspended swing which may be hung low for the use of children and which is provided with arm and feet inge'rating` means to provide healthful exercise and actuating,1 means for the swing.

A consideration in t-he manufacture and sale of all swings is their demountability, packing space and ease of assembly, since all these elements enter into the cost and market# ability of such devices. lt is therefore an object of my invention `to provide a complete demountable or knock-down swing, requin ing a minimum of work in assembly and dispensing., to a large extent, with the use of nuts and bolts whichjare often lost in transit and are often hard to replace in the particular size used.

The described and other features and advantages will be more fully apparent from the following detailed description when read in connection with the accompanying drawings forming part thereofand in which:

Figure l is a perspectiveview of the assembled swing,

Figure 2 is a longitudinal section on the line 2-2 of Figure l,

Figure 3 is a bottom plan view of the frame and corner uprights, only, assembled,

lfigure 4 is a detail of the mortise and tenon joint and interlocking1 wedge means of the frame members and uprights,

Figure 5 is a top plan view of the swing carriage proper, detached,

Figure 6 is a detailed view of the rear swing actuating` crank hanger. p

Referring` to the-drawings by numerals, l indicates the side members of a rectangw lar frame, and 2, the cross members `of this frame or base of the swing. From the junction ofthe side and `cross member of the swing, uprights 3 are provided, from the upper ends of which the swing proper is suspended by means of hangers journalled at their upper ends as will be later described.

The side and cross membersof the base frame of the swing.;r and the uprights attheir junction are interjoined into a rigid frame without the use of securingr devices such as screws or bolts as follows: The lower ends of the uprights are provided with vertical slots 4 therein substantially centrally thereof and have one edge formed with a wedgging bevel 5. The slots 4 of the uprights embrace short ribs 7, acting as tenons 7 and mortises 4, the ribs 7 being formed by mortisingj or chan` nelling the oppoiste sides of cross bars Q. forming mortises with which the lower ends of the uprights 3 at opposite sides of the slots 4 engage. The cross bars and uprights when thus-joined are seated on and locked to the side bars l by means of the following); structural. features. The side bars, adjacent to their ends are channelled on their inside faces as at 9 and are mortised at 8 on their outside edges to receive the tenons formed by the ribs 7 of the cross bars, these ribs beine' of a width equal to the thickness of uprights 3 and the channelled portions of the side frames; The channel 9 acts also as a mortise to receive thelower end of the uprights 3, one side of the channels being formed with bevelled or edging edges l0, which cooperate with the wedges of the uprigg'hts as the cross bars are forced down and seated on the side bars to `cause the uprights and cross bars wedgingly to'interlock with the side bars. The cross bars 2 are locked by the mortise and tenons 7-8 against looseningl movement lengthwise of the frame, and are rigidly held crosswise by theshoulders of the mortise 6 engaging; opposite sides of the side bars. rIhe uprights 3 are maintained in vertical position by the firm engagement of the lower slotted ends with the sides of the mortise 6 of the cross bar and bythe wedging interlock of its end edges with the sides of the mortise or channel 9 of the side bar 1. The described construction, While a knockdown provides for a rigid construction when assembled and interlocked as described. The upper ends of the uprights 3 are provided with vertical notches 7 therein to receive the rock arms l2 formed by offsets at the lil upper ends of the hanger for the swing itself. These 'hangers are, preferably, in the form ot' strong metal rods, theupper ends of which are laterally otl'set as .at 12 as described 'andV provided with enlarged heads 13 to retain them inthe slots 11. The hanger for the tor- Ward end of the swing is in the form, substantially otra U shaped bar ,L t'while the rhangerl for the rearV end ot the swing while o tfa ygenerally U-sha'pe 'is provided with a central crank portion i 16 bentupwardly from its lower ,end so that the portion 17 between the .crankl and .theside bars of the hanger 15 constitute rockshatts `or arms.

These hangers support a swingconstruction as follows: Runner bars 1S extending longitudinally. of the .base frame and' arranged in parallel, have notches 19 formed at alined points on .their lower edges in which the cross bar 2O of the front hanger 14 .journalto support the runners and in which the rock armsl? ofthe rear Ahangers 15 likewise i' seat and journal. Intermediate the ends ot the runners 1 8, there are formed upward eX- tensions 21 forming a seat base. The upper edgeof this base is provided with a pluralitgy7 Y of uniformly spaced sockets 22 into which seat studs23 projecting tromthe base of a bucket seat 24,adjustably to position this seat longitudinallyon the ibase 21. Pivoted at 25 on the inner sides of the seat base 21 are hand levers 26 connected by head. and nutat opposite ends of a cross rod 27 which .may be said to form a handle bar, andv having pivotally mounted thereon, kadjacent to their lower ends, connecting bars 28,v the lrear ends of whichl are split, as seen in Figures land 2 at 29,` andbored yto provide bearings Yfor the crank 16 ofV the hanger 15, bolts 30 retaining the cranks 16 in its' bearings atterthe same has been inserted Vthrough the split end 29. lTheV lower `ends Lot the handle bar levers 26 extend through slots 31 (Fig. 2) appropriately located in a foot board 32 which is hung from theseat'base 21 and corners 1S'by appropriate stirrups 33,. the lower end of the handle bar levers'thereby connecting this foot board with the `levers so that toot pressure applied through the suspended foot board 32 will cooperate with these levers and the crank bars128to Aoscillate the crank 16 and rock arm 1f? andcause the swing to move to and fro. The stirrups-BS are Vinserted from the n bottom of lthe foot board rthrough appropriate apertures and areretained therein by bends at their "lower ends, correspondingly bent cising device to develop their bodies. 'be no ted that vthe construction is such that scribed, it is to be noted that I have inclined the pairs of front and rear uprights 3 toward each. other and upwardly i'rom their .'base.. This, as will be seen from Figure 2 of the drawings, is for the purpose ot positioning-the side bars of the hangers perpendicular to the trame support or base with the swing section centered therein. The han gers for the swing section also act through their side bar and crank arms to .cross brace the runners 1S, these beingk additionally cross braced by the spanning seat 211 superimposed on the upward extensions 21 ot the runners.

The described construction provides a low hung swing, especially suital'ile l'or children, both for amusementpurposes an d as an exer- It will both arms and legs are conjointly exercised in operating the swing since the levers 2G are pushed forwardly and the toot board is pushed upwardly and baclnvardly by the seat occupant -lor actuation of the swing forwardly and the levers are pulled baclnvardly and the toot board downwardly and forwardly in the reverse movement of the swing, thereby naturally bracing the ieet and back lor the pull or thrust of the arms and giving complete muscular exercise. It will be obvious that the seat 24 can be easily adjusted on its base -to tit the child to the swing tor operating purposes, and that the thrust on 'the levers 26 or connecting handle bar 2T aided by foot pressure against the toot board or pedal 32 is effective to cause the swing to oscillate to and tro with its hangers in their supporting trame. It will also be evident that the described.construction may he disassembled and .packed piece-meal for shipment. This is true as to every portion ot the assembly, so that the minimum in the way oil nspace is required for packing. The simplicity olf the construction and the minimum ot bolts required makes its assembly a comparatively easy matter.
