BABY WALKER.

Specification of Letters Patent. Patented J an. 24, 1922.

Application filed April 28, 1920. Serial No. 377,276.

To all whom it may concern.

Be it known that I, EDWIN L. BOWMAN, a citizen of the United States, residing at Gardner, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Baby 'Walkers, of which the following is a specification.

This invention relates to baby walkers, and the primary object of the invention is to provide an improved baby walker which is so constructed that the same can be knocked down or collapsed so as to occupy a relatively small space in shipping or storage.

Another object ofthe invention is to provide an improved baby walker in which a made up lower frame is substituted for the costly hoop or guard member now used on baby walkers on the market, so as to reduce the cost and labor in making the walker.

7 A further object of the invention is to provide an improved baby walker having a novel upper frame for carrying the supporting seat and for forming marginal flanges for the food tray, so as to prevent articles from'being displaced from the tray.

A further object of the invention is to provide an improved means for associating the tray with the supporting structure so as to ermit crumbs or the like to be readily brushed off of the tray.

A still further object of the invention is to provide an improved baby walker of the above character, which is durable and efficient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

Other objects and advantages will appear in the following detailed description taken in connection with the accompanying drawings, forming a part of this specification, in which drawings:

Figure 1 is a perspective view of the improved baby walker.

Figure 2 is a fragmentary longitudinal section through the same.

Figure 3 is 'a bottom plan view of the upper supporting section, the legs bemg removed, and

Figure A is an enlarged fragmentary transverse section through the baby walker, showing the means of securing the tray to the upper supporting structure.

Referring to the drawings 1n deta ls, wherein similar reference characters designate corresponding parts throughout the sevtermediate cross bar 18.

eral views, the letter A indicates the improved baby walker which can be made out of wood, metal or any other desired material. The improved walker A includes the outwardly and downwardly inclined supporting legs 5, which have their upper terminals reduced as at 6 for insertion in the openings 7 formed in the longitudinally extending guide bars 8 of the upper supporting structuref), which will be hereinafter more fully described. The openings 7 are preferably at an incline to the perpendicular so as to permit the legs to extend outwardly at an angle to the upper supporting frame to forma relatively large supporting base for. the walker, so as to prevent the accidental tipping over of the same when in use. The lower terminals of the legs 5 are secured together by the longitudinally extending side bars 10 forming a portion of the lower frame 11. The outer terminals of the longitudinally extending side bars 10 are also reduced and tapered as at 12 for insertion in suitable openings formed in the legs 5. Transverse brace bars 13 are connected to the legs 5directly below the longitudinally extending brace bars 10 and the transverse bars 13 have their terminals reduced and fitted in suitable openin s formed in the legs 5. To prevent the accidental displacement of the longitudinal braces 10, and the transverse braces 13 from out of the sockets formed in the legs 5, and the legs against displacement from the openings or sockets 7 formed in the longitudinal brace bars 8 of the upper supporting frame 9, suitable screws 14 are provided for engaging the terminals of the brace bars and supporting legs as clearly shown in Figure 1 of the drawings.

The lower terminals of the legs 5 carry casters 15 which may be of any preferred form or type. The casters 15 permit the baby walker to be pushed around in any direction, by the baby.

The upper supporting frame 9 includes the oppositely extending side bars 8 and the end

transverse cross bars

16 and 17 and the in- The

transverse cross bars

16, 17 and 18 of the upper supporting structure 9 have their terminals tapered and fitted in suitable openings formed in the inner surface of thelongitudinally extending side bars 8. These brace bars are formed of material having a less diameter than the side bars 8 for a purpose which will be hereinafter more fully described.

The intermediate transverse brace bar 18 is arranged relatively near the forward transverse bar 17 so as to form end flanges for the tray 20 which will be hereinafter more fully described, and for forming a relativelylarge opening. inthe rear portion of the walker for the reception of the baby.

The tray includes a fiat rectangular plate 21 which is secured by suitable fastening elements 22 to the lower face of the longitudinally extending side bars 8, which form side flanges for the tray to prevent articles from being readily displaced off of the same. The

transverse brace bars

17 and 18 extend slightly above the upper surface of the plate 21 as clearly shown in Figure 40f the drawings,so as to permit crumbs or the like to be readily brushed off of the tray.

Directly in rear of the tray 20 and below the same is positioned a triangular shaped seat 23 on which the baby is adapted to sit. The triangular shaped seat 23 is supported by elastic straps 2e and 25 which are ar-' ranged respectively at the front and rear ends of the seat. The strap 24 is looped as at 26 and extended around the intermediate supporting transverse bar '18. The rear supporting straps 25 have their upper terminals looped as at 27 and extended around the rear transverse bar 16. The lower terminals of the supporting straps 24c and 25' are secured to. the seat 23 bysuitable fastening elements 28 as clearly shown in Figure 2 of the drawings; l/Vhen it is desired to toys, such as rattles, balls, rings and the like,

within easy reach of the baby so that the bab can play with the same when so desired. The 'rack 29 includes a pairof spaced uprights 30 and thecross bar 31 to which the toys are adapted to be tied by suitable strings or cords. The lowerends of the uprights 30 are reduced and fitted in sockets 32 formed in the longitudinally extending 'bars 8 and the reduced ends are held against displacement by the fastening elements 22. The rack 29 may also be used with high-chairs and the like, and the lower ends of the uprights 30 can be readily fitted in sockets formed in the upper surface of the tray or marginal flanges of the tray.

in shipping the improved baby walker, the legs 5 are removed from the upper frame 9 and laid on the upper surface of the same.

WV hen the legs?) have been removed from the upper section, the longitudinall extending side bars 10 and the transverse bars 13 forming the lower frame section 12 are also removed from the legs and placed upon the upper surface of the upper frame 9. The upri hts 30 of the rack 29 are removed from the sockets 32 and the rack is placed on the upper surface of the frame 9 with the other portions of the walker. This forms a relatively flat article which will occupy a minimum amount of space in shipping or storing.

From the foregoing description, it can be seen that an improved baby walker has been provided, which is exceptionally simple and durable in construction, and one which will effectively teach the baby how to walk.

Changes in details may be made without departing from the spirit or scope of the invention; but,

I claim:

1. baby walker comprising upper and lower frames, legs connecting the frames, caster wheels carried by the lower terminals of the legs, the upper frame including side bars and cross bars, a tray secured to the lower surface of the side bars, the side bars and certain of the cross bars forming -marginal flanges for the tray, the side bars being arrangedslightly above the upper surface ofthe tray.

2. A baby walker comprising an upper substantially rectangular frame, a lower substantially rectangular frame, diverging legs connecting the frames, rollers carried by the lower terminalsof the legs, the upper frame including longitudinally extending side bars, transversely extending end bars, and a transversely extending intermediate bar, the intermediate bar being arranged relatively near the forward end transverse bar, a .tray secured to the lower surface of the side bars adj acentto the forward'end thereof and disposed below the forward transverse bar, and the intermediate transverse bar, a seat arranged in rear of and below the tray, and straps connecting the seat with'the rear transverse bar and intermediate the transverse bar.
