ADJUSTABLE CHAIR.

Specification of Letters Patent.

Patented May 29, 191 7.

Application filed April 8, 1916. Serial No. 89,951.

To aZZ whom it may concern Be it known that I, GEORGE HENRY SAU'rmu, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented a new and useful Improvement in Adjustable Chairs, of which the following is a specifi cation.

The object of my invention is tomake an inexpensive serviceable chair that may easily be adjusted to vary the height of the seat to suit the requirements of diiferent sized persons and particularly to be valuable as a high chair for children in which case the seat may easily be adjusted downward as the child grows. The common high chair soon becomes too high for the child and then the ordinary chair is too low, during a period of a childs development. With my invention a single chair will answer for the child as it grows. Further hotels and restaurants can use my invention and meet all requirements of children with a single design of chair which is a desideratum.

Various different designs of adjustable chairs have been made but none of them of which I am aware meet the requirements as well as mine.

Reference will be made to the accompanying drawings in which Figure 1 is a side elevation of my chair. Fig. 2 is a plan View at the level of the top of the chair seat, the back being in section.

. Fig. 3 is a section of one front leg on line e e of Fig. i.

Fig. 4; is a side sectional elevation through the top portion of one of the front legs.

Fig. 5 is a front elevation of the top of one of the front legs.

Fig. 6 is a view on theopposite side from that of Fig. 5.

In the drawings 1 indicates any ordinary chair seat here shown as being made of wood. 2 indicates the back rails similar to many chair designs but in my case I provide central straight vertical portions 3 on the back rails where the seat joins them.

4 indicates the front legs on top of which there are telescoping sockets 5' sliding over the tops of the legs l and secured to the seat 1.

Fastened to the chair seat at the corners at the back are two clips 6 which embrace the back rails 2 in sliding contact with the vertical portions 3.

The straight portions 3 are provided with holes 7 adapted to be engaged by locking bolts 8 passing through suitable holes in the inside flange portion 9 of the clips 6.

-On the locking bolts 8 there are secured linger clips 10. The bolts 8 are hinged at 11 to levers 12 hinged at 18 to lugs 1i on the sockets 5 and the lower ends 15 of the levers 12 pass through slots in the back of the socket 5 and engage notches 16 in the front legs 4. Springs 17 hold the levers 12 normally in a locked position and at the same time hold the bolts 8 in a locked position in the holes 7 of the back rails.

Slots 18 in front of sockets 5 engage screws 19 in the legs and thus prevent the pockets 5 from being lifted clear off the front egs 4t.

In adjusting the chair seat downward to a lower position as indicated by dotted lines in Fig. l the operator stands in front and places his hands on the edges of the seat. at the middle of the sides and over the clips 10 and with the ends of his fingers on the clips 10 he unlocksthe bolts and levers and holds them unlocked while he pushes the seat down to a new desired position.

In adjusting the chair'upward the operator stands at the back and leans his body over the back and in that way holds the chair down while with his hands he releases the bolts and levers as before described and lifts the seat as desired to new positions.

The adjustments are easily and quickly made and may be accomplished when the chair is occupied by a child which is a desideratum.

What I claim is:

1. In a device of the class described an adjustableseat adapted to be raised and lowered and locked in different positions, and guided on the chair legs by sockets tglescoping the front legs and clips embracing the rear legs; with means on each side of the chair for simultaneously locking the sockets and clips to the legs.

2. In an adjustable chair a seat provided with sockets that telescope over the tops of the front legs and clips that embrace the back legs, notches in the legs adapted to re ceive locking members, locking levers hinged to the sockets of the front legs and held into engagement with the notches by springs,

locking bolts hinged to the levers and adapted to be actuated in locking the seat to the rear legs simultaneously with the action of the locking levers.

3. In an adjustable chair an adjustable seat adapted to be raised or lowered by sliding contact With the chair frame, clips and sockets secured to the seat and embracing the chair frame, locking devices mounted under the chair seat at the sides thereof and adapted to lock simultaneously the front and rear of the seat on the, same side.

4. In a chair of the class described an adjustable seat held in position in the chair frame by sockets and clips adapted to permit vertical sliding contact With the chair frame, locking levers mounted at one set of legs and locking bolts at the other set of legs and connected to operate together in releasing or securing the seat in the chair frame.

5. In a chair of the class described, an adjustable seat adapted to be adjusted in vertical sliding contact in relation to the V chair frame and back, and held at all four corners of the seat, sockets or clips secured to the seat and adapted to engage the chair from all four corners, the back legs of the chair forming the back frame as Well as the legs and having inclined portions at the top and bottom and straight portions at the middle Where the seat is secured, With means for locking the seat in different positions for height.

Signed at Chicago, county of Cook, and State of Illinois, this 6th day of April 1916.

GEORGE HENRY SAUTIER.
