OIERA'I'ORS CHAIR.

Specification of Letters Patent.

Patented Oct. 1a, 1919. 7

Application filed February 4, 1918. Serial No. 215,318.

To all 071,017]. it may concern.

Be it known that I, HARRISON H. EATON, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Operators Chairs, of wh ch the following description, in connectlon with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to chairs. The invention is illustrated as embodied in a folding chair especially designed for the use of machine operators.

The invention aims generally to produce a chair which, while inexpensive, will be more durable and safer than chairs of this type now generally used and which will still be convenient and comfortable for the operator.

Another object of the invention is to provide a chair of the general type referred to, which, without sacrifice of other advantages, will be so constructed and arranged as to avoid objectionable blocking of or encroachment upon factory aisle space.

The illustrated construction and arrangement requires only a minimum of aisle space when the chair is occupied, thus facilitating keeping the factory aisles clear, and at the same time is such that whenever the occupant leaves the chair, without special attention onthe part of the occupant, the chair immediately assumes a position such as materially to increase the aisle space, thereby facilitating aisle movements either of factory employees or of merchandise. This lastnamed characteristic is of conspicuous value in the event of any sudden emergency resulting in a general exodus of. employees, particularly in case of panic from other cause.

With this object in view, an important feature of the invention consists in providing a chair which can be secured to the floor in proper position relatively to the bench and which, when unoccupied, will assume a position immediately adjacent to the bench, preferably so that the seat will be partially under the bench and the back partially over it. In order that the rear legs of a chair so placed will not project into the aisle, arrother feature of the invention consists in providing means for causing the rear legs normally to approach the front legs and aissuIne a substantially vertical position near: the bench and thus leave the aisle clear when the chair is unoccupied.

Other objects and features of the invention will be apparent when the following description and claims are considered in connection with the accompanying drawings.

In the drawings Figure 1 shows, in full lines, a side elevation of the chair in position to be occupied and also shows, in dotted lines, the chair tipped forward with the rear legs folded up toward the front legs;

F g. 2 1s a rear elevation of'the chair in the position indicated in full lines in Fig. 1;

Fig. 3 is a cross section of the back showing the means for securing the back-rest in adjusted position; and

Fig. 4: is a detail of the base showing, in cross section, the means provided for adj usting the chair either toward or from the bench.

Referring to the drawings in detail, 10 is the frame having front legs 12 and a back 14 projecting therefrom. This frame, in-

cluding the extensions, is made, in the preferred c-onstruction,-of angle iron or other suitable structural material bent at a plurality-of points to give it the desired shape and, for convenience in manufacture, is made of two similar but oppositely shaped pieces secured together at the topby means of the plate 16 and rivets 18. The front legs are 4 pivotally supported to the base 20, the pivots being shown at 22. When in position for occupancy, the frame is supported by the rear legs 24 pivotally connected to the frame at 26. The upper portion of the rear legs forms one member of a toggle and a connect ing rod 28, pivotally connected to the rearlegs at 30 and to the base at32, forms the other member of the toggle. Thistoggle, when straightened, will cause the chair to pivot about the pivots 22and move forward into the dotted line position shown in Fig. l; at the same time the rear legs 24 approach the front legs so as to clear theaisle'for the purpose specified. A spring 34 secured at one end to the frame and at the other end to the rear'leg's causes the toggle to straighten and the chair to assume the folded position, when the occupant rises from the chair. The base 20 is composed of two members 20 and20", the member 20 being secured to the floor and the member 20 being mounted upon the member 20 for adjustm nt toward and from the bench, being locked in posit on by the b 3. an wing nut 38, as shown in-Fig; 4.

In the construction shown in the drawings, a seat 40 is secured to the frame 10 by means of two pieces of angleiron 4E2 bent as shown, and by a plurality of suitable fasteners 4d and 46, the scat A0 being secured to the angle irons 4:2 in any suitable manner. V a a 1 The seat and frame are constructed and arranged to be secured together in any one of a plurality of relative locations in order to provide a vertical-adjustment of the seat. A plurality of holes L8 are made in the ex ensi-on '14 of the frame, and corresponding holes 50 are made in the extensions 12 forming the front legs. The fasteners 44 and 46 pass through holesin the ends of the angle irons .42 and through any selected set of holes 48 and ,50 to adjust the seat to the desired height.

T o the extension 14 which forms the back of itrhQ chair, aback rest 52 is adjustably securedby the clamping plate 54:, the bolts 56 g and wing nuts'58, as shown in Fig. 3.

Having thus described-the invention, what is claimed as new and desired'to be secured by Letters Patent of the United States is 1.- A folding chair having, in combina.-' tion, a frame, front legs fixedly pro ecting rom the f ame, supporting mea s to w ich the front "legs are pivoted, .rearlegs pivotally connected to the frame, a pivotal connection between said suppcrting'means and th ear legs, a seat carried by the frame.

2, A folding chair having, in combination, a frame, front legs fixed-1y projecting from the frame, supporting means to which the ryint legs are pivoted, rear legs pivotally connected to theframe, means for causing the rear legs normally to approach the front legs, seat carried by the frame.

3. A folding chair having, in combination, a base, a frame having extensions form.- ing front legs pivotally connected to the base, rear legs pivotally connected to the frame, a connecting rod pivotally connected to the ba e. and the rear legs, means. for ausing he rear l gs n rm lly to a proach the front legs, and a seat carried by the ame n fixed relation theret 41 A folding chair, having, in combination, a frame, front legs projecting from the frame, supporting means to which the front legs are pivoted, rear legs pivotally con.- nected to the frame, a toggle, means for em nts! ret s may he wa ted tor frame and forming one member of a toggle,

a second toggle member connected to the rear legs and to the base, means for causing the toggle formed by said members to become straightened, and 'a seat carried by the" frame in fixed relation to the front legs.

:6. A folding chair, having, in combination, a frame composed of structural metal bent at a plurality of points to form the front legs, seat support and back of the chair, supporting means to which said front legs are pivoted, rear legs pivotally con.- nected to said frame and a seat carried by the frame. a w

7. A folding chair, having, in combina-r tion, a frame composed of structural metal bent at a plurality of points to form the front legs, seat support and back restof the chair, supporting means to which said front legs are pivoted, rear legs pivotally con-' neoted to'said frame, a seat, a plurality of fasteners for securing the seat tothe frame, the seat and frame being constructed and arranged to receive such fasteners in a pluralitylof relative locations.

I 8.'A folding chair having, in combination, a T-slotted piece provided with means for securingit to a floor, a base portion, a slot in said base portion, means passing through the -T-slot and the slot in the base portion for clamping the base portion in adjusted location, a frame, front legs projecting from the frame and pivota-lly mount ed on the base portion, rear legs pivotally connectedto said frame, and a seat carried by the frame in fixed relation to the front legs;

,9. An adjustable base for a chair having,

, on the base portion for securing a chair thereto. r

In testimony whereof I have signed my A name to this specification.
