`BABY-WALKER.

SPECIFICATION forming part of Letters Patent No. 517,403, dated March 27, 1894.

Application filed J une 29, 1893. Serial No. 479,189- (No model.)

T all whom t may concern,.-

Be it known that we, NELSON P. BRADISH and JAMES H. WILOOX, of Kansas City, Jackson county, MissourL'have invented certain new and useful Improvements in Baby Walkers and Tenders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

`accommodate children of various sizes and also to provide a yielding support therefor, and finally to produce a baby walker which 1s simple, strong, durable and inexpensive of construction.

With these objects in view, our invention consists 1n certain peculiar and novel features of construction and combination of parts as will be hereinafter described and pointed out in the claims.

In order that our invention may be readily understood, we will proceed to describe it wlth reference to the accompanying drawings, in which Figure l, is a vertical sectional view of a baby Walker constructed in accordance with our lnven'tion. Fig. 2, is a top plan View of the same. Fig. 3,is a detail perspective view of the seat portion of the device folded, and Flg. 4, is a detail perspective view of the table or stand also folded. Figs. 5 and 6, are detail perspective views respectively of the sections or links composing the upper/and lower rings of the device, and showing them in their folded position. Fig. 7, is a vertical sectional View of one of the telescopic legs and showing the spring having a right and left hand thread secured thereon in operative position.

In the said drawings, 1 designates a pair of horizontal and parallel side bars, these bars being of any ordinary .figuration desired, andv fitting at their opposite ends in couplings 2, and these couplings 2 are mounted upon caster rollers 3 of the usual construction and arrangement, so that the tread of the rollers may be presented in any direction desired.

A circular guard ring is composed preferably of four segmental sections, these sections being designated by numerals 4-5-6 and 7, and sections 4 and 5 at their adjacent ends are pivotally connected by a bolt 4a, the sections 5 and 6 are pivotally connected by a bolt 5a and the

sections

6 and 7 are pivotally connected by a bolt 6a, these several bolts being retained in position by retainernuts upon their inner ends. The free end of the section 7 carries a pivotal loop 7a which is adapted to engage and hold securely the adjacent end of the section 4. When desired as hereinafter referred to, the sections 4 and 7 may be disconnected by the operation of the loop 7a in the proper direction. In order to support these sections so that their upper surfaces shall be in the same horizontal plane, the section 4 carries an outwardly projecting ear or plate 4b which rests upon the upper edge of the section 5, and the section 5 carries an outwardly projecting plate or ear 5b which rests upon the upper edge of the section 6, and the section 6l carries an outwardly projecting ear or plate 6b which rests upon the upper y edge of the section 7, and the section 7 carries an outwardly projecting plate or ear 7b which rests upon the upper edge of the adjacent end of the section 4. It will thus be seen that these several sections carrying the plates or ears litting against the upper edges of the adjacent sections a suitable distance from their pivotal point, prevent any pivotal movement of any of the sections and hold them so that their upper surfaces shall b e iiush with each other,

and their lower surfaces shall be flush with each other, respectively. The several sections are engaged respectively in the recesses or notches 2a formed in the outer ends of the couplings 2, and being thus supported in a horizontal position near the oor,for1n a guard which, should the device be tilted sufficiently, would come in contact with the floor and prevent its entire overthrow. The section 4 is then brought against the outer edge of the adjacent end of the section 7, so that the loop 7 f thereof may be engaged therewith'so as to clamp the sections 4 and 7 firmly together. In order to brace this frame thus constructed,

IOO

i side b y a hinge 2l.

a pair of rods 8 are arranged horizontally and parallel with each ot-her, and are connected each to a pair of couplings 2--2 in any suitable manner, preferably by engaging tubular off sets 2c projecting from the inner sides of said couplings. These rods may be of hollow gas-pipe or simply solid rods as desired. The couplings 2 are also formed with the upwardly converging tubular projections or studs 2b which are preferably internally screw-th readed to receive the externally screw-threaded ends of the gas-pipes 9, and fitting telescopically in said gas-pipes and extending upwardly in the same direction for a suitable distance are the cylindrical rods or pipes 10. In order to adjust these rods longitudinally a rod of spring wire is bent at 11, and then has its opposite ends turned to form oppositely disposed or rightand

left hand screws

12 and 13 respectively, the right-hand threads 12 spirally encircling the lower portions of the rods 10, and the left-hand portions spirally encircling the upper portion of the gaspipes 9. rlheright-hand portion also engages shoulders 14 iixed upon the rods 10, and the left-hand portions engage shoulders 15 fixed upon the gaspipes 9. It will thus be seen by grasping the middle portions 1l of these springs they may be revolubly operated. to raise the rods 10 or to lower them as desired, and the object of this will be hereinafter referred to.

The upper or body-ring of the device is formed ot' a series of segmental sections 16- 17-18-19, and a section which is composed of a pair of similar segmental plates 20-20 secured together at their middle and under rlhe rear end of the section 16 is reduced in its upper and lower sides to form a circular tongue or projection 16, and concave shoulders 16, at the inner end of said tongue, and is also formed at the inner side and about centrally of said tongue or projection with a shoulder 16', this shoul` der being arranged radially toward the center of said body-ring. The tongue or projection 16b is pivoted upon the vertical pin 16c between the semi-circular and forwardly projecting ears 17, these ears 17 being arranged at their outer ends to lit snugly againstthe inner ends of the concave shoulders 16 of the section 16, and the section17is also formed with a radial shoulder 17b which is adapted to abut against the shoulder v161 of the section 16. rlhe section 17 is formed at its rear end in its upper and lower sides with recesses, the inner ends or shoulders 17a of which are concaved to form a circular and outwardly projecting tongue 17bl and at the inner side and about centrally of said tongue the section 17 is formed with a radially arranged shoulder 17". This tongue 17" is fitted between a pair ot' semi-circular projections 22 at the outer end of the section 2O and is piv- Aotally connected thereto by a vertical pivot pin 22, so that the outer margins of the projections 22 shall rest against the concave shoulders 17 of the recesses of the section 17. The section 2() is also formed at its inner side with the radially arranged shoulder 23 which abuis against the shoulder 17" of the section 17. The outer end ot the section 20is recessed in its upper side to form the concave shoulder2et and the forwardlyprojecting and circular tongue 25, and is also formed at itsinner side with a shoulder 26, this shoulderbeing arranged to extend radially toward the center of the body-ring. This tongue 25 engages acircular recess formed between the projecting ears 18, and is pivotally connected thereto by the Vertical pivot pin 18', of section 18,and arranged so that the segmental ends of said projections 18a shall lie snuglyagainst the inner concave shoulders 24. This section 18 is also formed at its innerside with the radially arranged shoulder 18b which ahuts against the shoulder 26 of the section 20, The outer end of the section 18 is reduced in its upper and lower sides to form a circular tongue 18, and concave shoulders 18d at the inner ends of said tongue and at its upper and lower sides, and is also formed about midway ot' said tongue and at its inner side with the radial shoulders 18, The tongue 18c tits in a circular recess formed between the projec tions 19 of section 19, and. is pivotally connected thereto by the vertical pivot pin 19t", and arranged so that the segmental end ot' said projections 1li shall fit snugly against the shoulders 1860i' sections 18. The section lf) is also forlnetl with a radially arranged shoulder 1f)r which abuts against the radial shoulder 18o of the section 18. The opposite end of the section 19 is recessed at its upper and lower sides to form the tongue orprojcction 19', and at the inner end of said tongue the segmental shoulders 19h, and about midway of said tongue the radially arranged shoulder 19'1. This tongue 19g is adapted to engage the circular recess formed between the projections 16l of the sections 16, and is pivotally connected thereto upon the vertical pivot pin 16c so that the segmental ends of said projections 16d shall lie snugly against the concave shoulders 19Il of section 19, and so that the shoulder 16f formed at the inner side of said section shall abut against the shoulder 19'101' section 19. It will thus be seen that these several sections pivotally connected together as described form a complete circle or body-ring,and that the radial shoulders thereot' bearing against each other pre vent any twisting movement oi said bodyring. The

front sections

16 and 19 and the

side sections

17 and 18 adjacent to their rear ends are formed with diverging and downwardly projecting tubularstuds 30, and these studs are preferably internally threaded to receive the upper threaded ends ot' the rods or pipes 10. It will thus be seen that when desired, by operating the springs the bodyring may be raised or lowered in a horizontal plane when desired. Depending from said body-ring are a suitable number of hooks IOO 31, and these hooks are adaptedV to engage one of a series of openings 32 formed in a corresponding number of straps 33, these straps being secured at their lower ends to a pair of segmental brackets or plates 34, these brackets or plates being hinged together at their middle at 35 and forming together at their inner margins approximately a semicircle, the open side of which is toward the front or diametrically opposite to the hinge 21 of sections 20 and 2Oa of the body-ring. A flexible seat 36 of leather preferably filled with hair or other suitable cushioning material is securedtto the brackets or plates 34. It will thus be seen, that we have provided a seat in which the child may twist or turn to acertain degree and at the same time a seat the position of which may be changed relative to the body-ring when desired, by means of a series of openings or holes 32. In order to provide a table or stand in front of the child two segmental plates or boards 37 are provided, each of which is provided at its outer and curved vertical edge with the upwardly projecting flange or retainer wall 38. These sections are adapted to fit and are hinged at 37a closely together at their under side upon a line radial to the center of the body-ring. The inner edges of these plates are formed concave at 39-39 to correspond with and lit against the outer curved edges of the

sections

16 and 19, and in order to secure the table or stand rmlyin position a pairof horizontal and rearwardly projecting pins 40 are provided, one of these pins 40 projecting from the concaved edge 39 of each plate 37 and fitting in a bearing or loop 41 secured to the under sides of the

sections

16 and 19.

It will be seen from the foregoing, that the child upon the seat'36 by pressing or pushing with its feet upon the door may move the device in any direction desired, and that by operating the springs referred to the seat may be raised higher or lower to accommodate children of various sizes, and that by providing the stand or table the device may be used as a support for the child during meals and other times. v

When it is desired to move this chair from place to place or upon a trip, the table or stand may be det-ached from the body-ring and folded to the position shown in Fig. 4.

The seat may now be detached from the hooks 31 and folded also to the position shown in Fig. 3, the iiexible body-portion 36 allowing said operation to take place, and the straps 33 of course may be folded up against the bodyportion. The body-ring may now be disconnected from the upper ends of the rods 10, and the pivot pin 16e connecting the

sections

16 and 19 removed. The portion composed of the sections 18-19 and 2Oa may now be swung upon the hinge 21 up against the under sides of the portions composed of the sections 16-17 and 20, and these semi-circular portions may then be straightened out to a certain extent, the peculiar pivotal connection allowing said movement to take place, as shown in Fig. 5. The loop '7a may now be swung in the direction of the arrow, Fig. 2,'to clear the end of the section Llso that thelower ring may be disconnected from the recesses 2iL of the couplings 2. The sections 5 and 6 are now swung downward upon thev pivot 5a until the section 5 lies snugly within the section 6. Section 7 is now swung downwardly upon pivot 6%until it lies snugly against the outer side of section 6, and section t is pivotally operated upon pivot 4 until it lies snugly against the inner side of section 5, as clearly shown in Fig. 6. The couplings may now be removed from the cross barsl and the cross bars 8, and if desired the pipes 9and 10 may also be disconnected. It will thus be seen that the device may be taken quickly and easily apart, and folded into a package or bundle so small that it may easily be carriedfrom place to place with very little inconvenience, and may if desired be placed in a large hand grip; thus obviating the necessity of sendinga device of this character by eX- press, where it would be liable to be broken, and also inconvenient to reach until the journey was ended.

From the above description it will be seen that we have produced a baby walker, which is simple, strong, durable and inexpensive of construction, which is easily portable and which may be adjusted to accommodate children of various sizes, and which nally by means of` the springs encircling the pipes 9 and l0 provides a yielding support for the'occupant. It will also be seen that the lower or guard-ring will prevent the device being overthrown or knocked over. n

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

` 1. In a baby walker, the combination with a suitable framework, of a guard-ring carried by said framework, and consisting of a series of segmental plates pivotally connected together, and provided with ears or lugs to hold said plates in the same plane, one of said plates being detachably connected to the adjacent end of another section, substantially as set forth.

2. In a baby-walker, the combination with a frame, and a body-ring carried thereby, of a series of upwardly converging pipes carried by said frame, and a series of downwardly diverging pipes carried by the body-ring and IIO fitting telescopically within the first named pipes, and collars rigidly carried by each series of pipes, and springs each bent to form a right and left hand screw, the right hand screws spirally encircling one series of pipes and their collars, and the left-hand screws spirally encircling the other series of pipes and their collars, substantially as set forth.
