:BABY WALKER.

Application led February 23, 1927. Serial No. 170,285.

This invention relates to an improved device which is commonly known in the trade as a baby walker.

My primary aim is to generally improve upon-devices of this class by providing one of comparative simplicity and durability, wherein they parts are improved, are arranged in a new organization and wherein the parts interact in a manner to insure etticiency in operation and to facilitate walking of the occupant.

One feature of the construction is the formation of the support which includes an annular base ring, and supporting uprights which are made up of adjustably connecting sections to permit the elevation of the seat, which is supported thereon, to be changed to accommodate the occupant.

A primary feature of importance is the head or top member which is swivelly mounted to allow easy turning with respect to the support, whereby to enable the child occupant to readily face the direction in which the main support might accidentally travel, thus serving to facilitate comfortable walking.

Other feautres and advantages of the invention will become apparent from the following description and drawings.

In the drawings Figure 1 is a top plan view of a structure constructed in accordance with the present invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is an enlarged cross section through a portion of the head construction.

Referring to the drawings in detail, it will be seen that the reference character 1 designates a base ring which is here shown as being made up of two semi-circular sections 2 having their ends arranged and connected together in overlapping relation. This ring carries suitable swivelly mounted casters 3.

Rising from this base ring at circumferentially spaced points are the uprights or supporting legs 4, each of which is composed of upper and

lower sections

5 and 6 respectively connected together by pin and slot connections 7. The sections are of the proper curvature, and constructed .as shown. and can be adj usted vertically to vary the elevation of the head 8 which is supported on the upper inturned ends thereof.

It will be of interest to note that the lower ends of two of the legs are connected to the overlapped ends of the sections 2 of the base ring, a single fastening bolt being employed in both instances. The seat 9 which is of Ordinary construction, is suspended by elastic r yieldable suspension elements of any suitable construction.

Particular emphasis is to be laid on the construction of the head which includes a main wooden annulus 11 having a downturned inner edge portion 12 cooperating with a supplemental annulus 12. The last named annulus is bolted by fastening bolts 13 to he inturned ends of the upper sections of the legs.

Attention however, is called to a keeper strip 14 which is fastened to the downturned flange 12 and which has one edge projecting beneath and in overlapping engagement with the under side of the supplemental annulus 12. The section 11 is freely rotatable with respect to the section 12 and in order to facilitate this, I provide anti-friction balls 15 which roll in grooves formed in the metal facing plates or

runners

16 and 17 respectively.

The plate 17 is provided with an upstanding marginal iiange 18 which operates as a spacer and confining element.

It is thought that by considering these details of description in connection with the accompanying drawings, a clear understanding of the construction and advantages as well as operation will be had. Therefore, a more lengthy description is thought unnecf essary.

W'hile the preferred embodiment of the invention has been shown and described, i is to be understood that minor changes coming within the field of invention claimed, may be resorted to if desired.

Having thus described my invention, what I claim as new is In a baby walker of the class described, a base ring, casters connected to said ring at circumferentially spaced points, supporting legs connected with the ring at circumferentially spaced points and composed of upper and lower slidably connected sections, the upper ends of the upper sections being directed laterally and inwardly toward each other, an annulus rigidly fastened to said inturned ends, a second annulus superimposed upon the irst annulus, and relatively rotatable with respect to the latter, the second named annulus having` its inner edge downtnrned. a keepei1 sti-ip Carried by said down turned edge and engaged beneath said iist named annulus, facing plates carried by the opposed faces of said annuli, one of said plates having its outer edge formed With an upstanding flange providing conining means and spacingl means, and anti-friction balls disposed bel0 tween said facing plates.

In testimony whereof I afiiX my signature.
