MERRILL W. HARD, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF TO W. LEWIS MACK, OF CHICAGO, ILLINOIS.

CHAIR.

Application filed August 18, 1919. Serial No. 318,178

To all whom it may concern:

Be it known that I, MERRILL IV. HARD, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented certain new and useful Improvements in Chairs, of which the following is a specification.

This invention relates to improvements in chairs.

My improved chair is especially designed and adapted for use in theatres, auditoriums and the like where it is desirable to economize space or install the largest number of seats possible in any given area.

The main objects of this invention are:

First, to provide an improved chair, the seat of which may be easily moved back by the occupant thereof to permit the passing of persons between rows of chairs without compelling the occupants to stand.

Second, to provide animprovedchair having these advantages which is strong and durable in structure and at the same time comparatively light in weight and eco nomically produced and installed.

Further objects,'and objects relating to structural from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Fig. I is a side view of the chair embodying the features of my invention in normal position, a second chair being indicated in operative relation thereto by dotted lines.

Fig. II is a side elevation, with the seat in its retracted or rear position, the second chair being also here indicated by dotted lines.

Fig. III is a detail front view with the seat in its raised position.

Fig. IV is a vertical section from front to rear, the retracted position of the seat being indicated by dotted lines.

Fig. V is an enlarged detail section on a line corresponding to line 55 of Fig. VI showing structural details of the seat suport.

p Fig. VI is a sectional view through the seat and one of its ways, the seat being details, will definitely appear shown in its forward or normal position by y 1full lines and in its rear position by dotted ines.

Fig. VII is an enlarged detail view partially in section on a line corresponding to line 77 of Fig. VIII showing details of the end member mounting.

The seats 3 and the back 4 are shown more or less conventionally and may be upholstered or finished as desired. The back is rigidly mounted on the side members or plates 5 which'are carried by'the swinging standards 6 pivoted on the pedestals 1.

The upper endsof the 'standardsG are tapered to provide point bearings 7 which engage the V shaped bearing recesses 8 in the bearing plates 9 secured at the upper edges of the end members 5. These. end members, 5 are, in the structure illustrated, formed of sheet metal,'the same being provided with ears 10 folded over the bearing plates or blocks 9 which are retained by the rivets 11. The cars 10 have segmental slots 13 which are engaged by pins 14 for retaining the parts in their assembled relation.

The standards have forwardly projecting arms 15 having slots 16 therein engaged by the pins 17 on the pedestals to limit the swing of the standards and thereby limit the movement of the seat. The seat 3 is mounted on pivots 18 carried by the side members 5, the seat having U shaped brackets 19 on their under side to engage these pivots. See Fig. V. H

The seats are further supported by the rollers 20 mounted on the pedestals, the

seats having channel shaped ways 21" the chair tends to carry it forward. I

The pivots 18 are located in the lower a frame in the.

front corners of the side members and in advance of the vertical plane of the bearing for the side members on the supporting standards.

Links 22 are pivoted at 23 on the pedestals, their upper ends being mounted on the ivots 18.

Thus arranged, when the seat is pushed back. as shown by dotted lines in Fig. IV, the side members are rocked or tilted forwardly thereby swinging the back forwardly as shown by dotted lines in said figure.

The end pedestals are braced by means of the cross braces 24:. e

With this arrangement of parts, the seat may be swung up against the back as is shown in Fig. 111 and when in lowered position may be pushed back by the person occupyin the sane, to provide passage in front or the occupant thereby avoiding the necessity of his arising to permit persons to pass. lhe parts are arranged so that the weight of the occupant tends to carry the chair to its forward or normal position, little effort, however, being required to push it back, when desired.

I have illustrated and described my improvements in an embodiment which I have found very practical. I have not attempted to illustrate or describe other embodiments or adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The combination with side pedestals, of a seat and a back, standards pivotally mounted on said pedestals and having tapered bearing portions at their upper ends and forwardly projectingslotted arms, pins on said pedestals engaging the slots of said arms, side members on which said back is rigidly mounted, provided with hearing plates at their upper edges having bearing recesses coacting with said bearing portions of said standards, pins on said standards engaging segmental slots in said side members whereby said members are retained on said standards, pivots for said seats disposed on said side members in front of their hearing point on said standards, links pivoted on said pedestals in front of said standards and engaging said seat pivots, seat supporting rollers on said pedestals, and channeled ways on the under side of said seat traveling on said rollers, said ways being forwardly inclined so that weight on the seat tends to carry the seat forward, and a support for the forward end of the seat.

2. The combination with side pedestals, of a seat and a back, standards pivotally mounted on said pedestals and having tapered bearing portions at their upper ends, side members on which said back is rigidly mounted, provided with bearing plates at their upper edges having bearing. recesses coacting with said bearing portions of said standards, pins on said standards engaging segmental slots in said side members whereby said members are retained on said standards, pivots for said seats disposed on said side members in front of their bearing point on said standards, links pivoted on said pedestals in front of said standards and engaging said seat pivots, seat supporting rollers on said pedestals, and channeled ways on the under side of said seat traveling on said rollers, said ways being forwardly inclined so that weight on the seat tends to carry the seat forward, and a support for the forward end of the seat.

3. A chair comprising side pedestals, standards pivotally mounted on said pedestals, a seat having its rear portion suspended from the upper portion of said standards and its forward portion resting on guides on said pedestals, a back mounted on said seat, and links connecting said seat with said pedestals.

4. A chair comprising side pedestals, a seat provided with upwardly projecting side plates, standards pivotally mounted on said pedestals and having their upper extremity engaging said side plates above the level of said seat to form suspension support for the rear portion of said seat, rollers on said pedestal forming a support for the forward portion of said seat, a back mounted on said seat, and links connecting said seat and said pedestals.
