HIGH CHAIR.

Specification of Letters Patent.

Patented J 11118 20, 1916.

Application filed July 2, 1914. Serial No. 848,649.

To all whom it may concern:

Be it known that I, GEORGE H. BARSCHOW, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certainsnew and useful High Chair; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to folding chairs, and particularly to a high-chair, but is not restricted to such use as it may be used in any connection for which it may be adapted or appropriate.

The primary object of my invention is the provision'of ahigh chair of the character described, which is easy and inexpensive to manufacture, light, strong and durable in its construction and capable of being folded or collapsed into compact form to facilitate a packing or storing thereof.

Further objects and advantages of the invention will be apparent from the following detailed description thereof.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of a'chair embodying the invention in set-up form. Fig. 2 is a side view of the chair partly col lapsed, and Fig; 3 is a similar view of thechair completely collapsed.

Referring to the drawings, 1 and 2 designate forwardly extending base members or bars which coiiperate' with front and rear cross-bars 3 and 4,, respectively, to form a base frame of rectangular form. Pivotally rising from the base members or bars 1 and 2, adjacent to the front and rear ends thereof, are upright bars 5 and 6, respectively, which, in the present instance, are of the same length and have their lower ends formed with outwardly projecting feet 7 for resting on a floor or other subjacent support when the chair is in set-up position. The front corner bars 5, 5 are carried, in

the present instance, at the outer ends of the cross-bar 3 and are connected, substantially midway of their upper and lower ends by a cross-bar 8, while the rear corner bars 6, 6 are pivoted to the respective bars 1 and 2 1n advance of the cross-bar 4:, as at 9, and are connected intermediate their ends by a cross-bar 10.

An upper frame is collapsingly carried by the corner uprights or bars 5 and 6 of the lower frame, and comprises the front corner uprights or bars 11, 11 and the rear corner uprights or bars 12, 12, which pivotally rise from the upper ends of the respective uprights 5 and 6. The pivots 13, which connect the respective front uprights 5 and 11, are disposed above the lower ends of the uprights 11 to provide such uprights with the downward extensions 14, which lap the sides of the lower uprights 5 and have their free ends notched to coact with pins 15 on the respective bars 5 to permit the bars 5 and 11 to have folding or collapsing movements in a rearward but not in a forward direction from upright or vertical position. A crossbar 16 forms the connecting pivot for each pair of rear uprights 6, 12. A seat frame 17 has side-bars 18 which are pivotally connected at their front and rear ends to the respective front and rear bars 11, 12, such seat being disposed intermediate the lower and upper ends of the bars 11, 12. Arm rests 19 are disposed in parallel relation to the seat 17 and are pivotally connected at their rear ends to the respective uprights 12 below the upper ends thereof, and are pivotally connected at their forward ends to the upper ends of the respective uprights 11, as shown. A back 20 extends downward from the upper portion of the rear uprights 12 being pivotally connected at its lower end to the seat'bars 18, by links 21 and at its upper end to the upper end portions of the rear uprights 12, as at 22. The rear uprights 12, 12 are connected at their upper ends by a cross-bar or member 23, which is preferably integral therewith.

24; designates a tray, which is carried by A foot-rest 26 is provided below the seat 17 and is carried, in the present instance,at

the forward ends of horizontally-disposed side bars 2727 in advance of the uprights 11, said side bars being pivotally carried at their rear ends. by the cross-bars 16 and adjacent to their forward ends by the pivots 13. c t H i A diagonally-disposed bracing link 28 is disposed at each side of the chair and has its forward end pivotally carried by the seat pivot 29 of the respective front upright 11, and has its rear end pivotally connected to the rear upright 6 below the crossbar 16, as at 30, thus causing the lower and upper frames of the chair to have uniform folding and unfolding movements, and preventing an independent folding or unfolding of one relative to the other.

A jointed brace 31, having a knee-joint 32, is disposed at each side of the lower frame of the chair and has its forward end pivotally connected to the respective end of the cross-bar 8 and its rear end pivotally connected'by thepivot 9 to the respective frame u'pright 6. When the chair is in upright position the brace-bars 31 are in straight bracing relation and prevent a collapsing of the chair until the knee-joint 32 of each bar is broken for such purpose.

33, 33 designate small wheels, which are carried by the cross-bar 4 near the ends thereof and are so disposed that they are free from contact with the floor or, other subjacent support when the feet 7 V of the lower chair frame are resting on the floor. A slight rearward tilting of the chair will, however, move the wheels 33 into rolling contact with the floor. It frequently happens that a baby, when sitting in a highchair, will push its feet against a table or other stationary means adjacent to which 7 the chair is placed and cause a rearward tilting of the chair, which tipping sometimes results in injury to the baby. By the provision of the wheel 33 it is impossible. to tip the chair over in this manner, for as soon as it is tipped slightly to the rear, the

wheels 33 will be brought into rolling con tact with the floor so that the chair will roll outwardin upright position from the object against which the baby is pushing.

It is preferable to make the frame parts of strap metal, as shown, as a chair of light and strong construction is thereby provided.

It is evident with this construction of'chair that it is composed of few parts, and it is .foldable into compact form for shipping or storing, as shown in Fig. 3, or may be quickly and easily unfolded toset-up position, thus admirably adapting it for use by hotels, restaurants, and the like, as well as in private houses. 7 W

I wish it understood that my invention is not limited to any specific construction, form or arrangement of the parts, as numerous .modificationsmay be made without depart-.

ing from the spirit of the invention.
