Specification of Letters Patent.

Patented Oct. *7, 1913.

declare the following to be a full, clear,

and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to furniture and it has for its object to provide a seat, chair or other body support for infants or children by means of which they can be supported in an upright sitting posture otherwise unobtainable because of weakness or a general disinclination on the part of the occupant to assume and retain such a.

position.

The invention further has particular reference for providing a device of this nature that can be conveniently and usefully employed in the studio of portrait photographers to assist them in gaining the desired poses of child subjects without necessitating the appearance of an attendant to the child in the photograph.

To these and other ends the invention consists in certain improvements and combi nations of art all as will be hereinafter more fully escribed, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a perspective view taken from a rearward point of a body support in the nature of a chair constructed in accordance with and illustrating one embodiment of m invention, a child being shown in positlon therein; Fig. 2 is a perspective view from a forward point with the parts in practically the same positions of adjustment; Fig. 3 is a central vertical section through the chair back and adjacent portion of the bottom, and Fig. 4: is an enlarged detail front elevation of the waist supporting clamps.

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

In the present exemplary embodiment of the invention a chair or seat is shown comprising, as to the general elements, a bottom 1 and back support 2 only, it being intended that the chair be placed upon the seat of a larger chair or table in lieu of providlng legs or other supporting parts. The chair should preferably be invisible and by this structure can be used as well when it 1s desired that the occupant be represented as sitting on the floor, for instance.

It is desirable that the chair'be of knockdown construction for convenience in packlng and shipping and to this end the lower portion of the back has an open slot 3 that sets within an opening 4 in the rear of the seat, being secured to the latter preferably by a bolt 5 and thumb screw or nut 6 that is received within the slot 3. Ext-ending vertically and preferably centrally, of the back, is a slot or guide 7 through which extends from front to rear a bolt or spindle 8 having a head 9 rigid therewith and disposed on the front face of the back, while the rearwardly projecting end has a threaded engagement with a clamping wheel or member 10. The head 9 is provided on its rear face with parallel transverse guides 11 to receive the shank portions 12 of waist supporting arms 13 disposed at either side of the chair. These arms are preferably curved inwardly approximately as shown to conform as nearly as possible with the body of the child and after being widened to receive the latter are pressed inwardly toward each other beneath the childs arms in the region of the waist and hold it against swaying movement, at the same time supporting it beneath the arm pits if so desired.

The shank portions 12 embody racks 14 meshing upon opposite sides of a pinion 15 loosely mounted on the spindle 8 between the guides 11 and are thereby connected for simultaneous movement during their lateral adjustments so that other than a symmetrical disposition thereof is impossible and the occupant is held centrally on the seat. To secure the arms in their various positions of adjustment the clampingmember 10, loosened during their adjusting movement is tightened to react against the rear of the back and thereby draw the head 9 rearwardly to clamp the shank portions 12 between it and the front face of the back, as will be readily seen from an inspection of Fig. 3. This same clamping action is also utilized to adjust the arms bodily and in utilizes: its clothing to! attach it to the back support. To this end an opening 16 is formed in; the latterwith which the slot 7 communicatesto form in. effect a restricted portion thereof and in use an end of the childs garment ispassedthrough such open-- ing and wedged. down within the slot. To

jmcludmg a back having a vertical slot orfurther insure its retention I prefer to provide an additional. securing member in the present form of'a preferably resilient plate or lever 17 which is pivotally mounted on; the spindle 8 between. the clamping member lOwand the back support- It is thus permitted to swing transversely of the slot 7' and to further wedge the rearwardly projec-ting portion: of the garment between itself and the rear face of the back support, as is clearly shown in Ifiig. 1, the cloth of the garment being indicated by the numeral 18; The clamping memberlO is also obviously common to this part, but to prevent too loose a movement thereof and also to allow its operation while sufficient clamping pressure is communicated to the-head 9 to prevent the attendant structure from slip-- ping down the slot 7, it is preferable to interpose a spring 19 between thesecuring and clampingmembers, as shown in Fig. 8, the same being housed within a recess 20- in the latter to exert its yielding pressure a little inadvance of'the ultimate rigid contact produced.

' It is obvious that my invention could be used apart from the exact combination shown with a chair or seat as the back sup port, suitably mounted, might clearly be used; alone with its; attachments to hold the child in a standing position. I also wish to make mention of the fact of itsbeing plain that the opening 16 in the back support: for 1' the initial insertion of the clothing need not be entirely inclosed, as shown, asit might be open at the top without destroying the function of the converging portion adjacent the slot 7 which directs the material within the latter.

I claim as my-invention:

1. A body support comprising'a back provided with an opening embodying an enlarged portion through which a part of the clothing of the occupant may be passed and a relatively restricted portion or communieating slot, adapted to subsequently receive and wedge the clothing, a pair of rigid waist sua ortin arms dis osed at o osite sides 1 p a F of the back and a carrying member therefor adjustable in the slot. 2. A body support comprising a back pro vided with an opening embodying an enlarged portion through which a part of the clothing of the occupant may be passed and a relatively restricted portion or communicating slot adapted to subsequently receive and Wedge the clothing, a pair of rigid waist supporting arms disposed at opposite sides 1 of the back and laterally thereof, a carrying member therefor adjustable in the slot in the back and-a securing member pivoted tov the carrier to move across the'back transversely of the slot to wedge. aprojectingportion of jsuchv clothing between it and: the back.

3. The combination with a body support gguid'e therein, of a vertically adjustable spindle extending throughv theslet and proivided with. a head on: one: side of the back,

a pair of waist supporting arms arranged at either side ofthe: support. having shank V portionsembodying rack bars guided in the head, a gear loosely mounted on the spindle I tocooperate-with. both rack bars and: insure l simultaneous lateral ad usting movements of the arms in opposite directions,- and a clamping member engaging the. spindle onjthe other side and reacting against the latter to lock the shank portions of the arms between the head and backagainst both vertical and lateral movement. 7

4. The combination with' a -body support through the back and provided; with a head the support having shank portions embodying rackbars guided-1n the head, a gear iloosely mounted on the spindle to cooperate g with both rack bars and insure simultaneous lateral adjusting movements of the arms in jopposite directions and a clamping member jengaging the'spindle on the other side of the'back and reacting against the latter-to lock the shank portions of; the: arms between the head and back in their different positionsof lateral adjustment. r V 5. The combination with a body support including a back, of a spindle extending on one-side of the latter, a pair of" Waist; supportlng arms arranged at either side of. V
