JOHN S. LYON, OF ROCHESTER, NEW YORK, ASSIGNOR 0F ONE-HALF T0 TRAUGO'I'T C. UHLEN, OF ROCHESTER, NEW YORK.

BABY-WALKER.

Specification of Letters Patent.

Patented Apr. 2d, 1917.

Application filed Qctober 24, 1914. Serial No. 868,526.

To all whom it may concern:

Be it known that 1, JOHN S. LYON, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Baby- Walkers; and I do hereby declare the following to be a full, clear, and exact description. of the same, reference being bad to the accompanying drawings, forming a part of 1 this specification, and to the reference-nus merals marked thereon.

My invention relates to baby walkers, baby jumpers, or similar devices for bold ing babies, particularly of the form which generally employ a pair of annular frames or rings arranged one above the other, the upper ring being the smaller and forming a rest for the baby, while the lower ring is larger, and constitutes a base for the device, and the object of the improvement is to provide a novel construction that enables the apparatus to be folded or collapsed by the provision of connections between the pair of rings, whereby one can be moved relatively to the other so that they lie in coincident or adjacent planes. To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Figure 1 is a plan view of a device constructed in accordance with my invention, and showing the parts in operative position;

Fig. 2 is a side elevation of the same;

Fig. 3 is a plan view showing the parts folded;

Fig. 4 is a detail elevation of a portion of one of the connections between the rings;

Fig. 5 is a sectional view on the line 5 5 of Fig. 4;

Fig. 6 is a sectional view on the line (S -6 of Fig. 4, showing the parts in-a position, which they assume while being adjusted and,

Fig. 7 is a sectional view on the line T -7' of Fig. 4.

Similar reference numerals in the several figures indicate the same parts.

The invention is shown as applied to a well known type of baby walker, although it will be understood it is not to be limited to this particular construction, as it may be 'ing frame B applied with equal facility to other forms of baby supporting devices. In the present embodiment, A designates a base frame preferably in the form of a ring or annular member adapted to rest upon a floor, and mounted upon casters a, whereby it may be readily moved about. B designates a supporting frame, preferably in the form of a ring or annular member of less area than the base frame, and adapted to be arranged above the latter when the parts are in operative position. as shown in Fig. 2. The supporting frame 13 is mounted on the base frame by means of a plurality of extensible connections, which permit the supporting frame to be folded upon the base frame in a manner that will presently be described. C designates a seat carried by the supportand suspended by yieldable comprising springs o and straps 0 Also mounted on the supporting frame B is a tray D.

When the device is not in use, it is highly desirable that theparts be folded, so that it can be stored in a minimum amount of space and present less likelihood of the parts being damaged or broken. To this end I employ extensible connections between the frames, consisting of relatively movable members, and means for holding them in adjusted relation. Each of the extensible connections consists of a pair of relatively slidable members, designated at E and E, and pivoted to the base frame and supporting frame respectively. These members may comprise rods bent upon themselves to form parallel bars, one of said members having an end portion 6 for a purpose that will appear presently. The member E is fixedly connected to a guide or plate 6 having flanges c and e at opposite ends. The flange e is provided with openings to receive the bars of the member E, which also pass through elongated openings 6 formed in a flange c that is suitably secured on the guide, permitting the member E to be moved from the position shown in Figs. 4

connections and 5 to that illustrated in Figs. 3 and 6.

the position shown in Fig. 4 to that shown in Fig. 6. When the keeper is in the position illustrated in Fig. 4:, the member E is held against relative movement, and by moving the keeper to the opposite end of the guide, the connection can be collapsed by first moving the member E within the slots 6 until the end portion 6 clears the flange 6 The members can then be moved slidably on each other, and the supporting frame depressed until the parts assume the position shown in Fig. 3.

I claim as my invention:

1. A device for holding babies comprising in combination a base frame, and a supporting frame of less area than the base frame and mounted thereon by means of a plurality of extensible connections permitting the supporting frame to be arranged in spaced relation above the base frame or folded upon the latter, said extensible connections each comprising a pair of members pivoted to the base frame and supporting frame respectively, a guide connected to one of said members, the other of said members being slidable through openings of the guide, the guide having a recess to receive one end of the relatively slidable member when the members keeper movable on the guide and co6perat- Copies of this patent may be obtained for five are extended, and a ing, when in one position, with said relatively slidable member to hold the end referred to in said recess, and in its other position to release said relatively slidable member and permit the connection to be collapsed.

2. A device for holding babies comprising in combination a base frame, and a supporting frame of less area than the base frame and mounted thereon by means of a plurality of extensible connections permitting the supporting frame to be arranged in spaced relation above the base frame or folded upon the latter, said extensible connections each comprising a pair of members pivoted to the base frame and supporting frame respectively, a guide attached to one of said members and having a flange thereon, the other member embodying a pair of bars movable through openings in said flange, said guide having a recess within which the end of the last mentioned member may be located to hold the connection extended, and a keeper slidable on the guide and cooperatmg with said member to hold said end within the recess.
