ZZZ? 72 017765. Z 255 72757" WW MW JOSEPH SALOMON, OF CHICAGO, ILLINOIS.
INDUSTRIAL CHAIR.
Specification of Letters Patent.
Patented May 1919..
Application filed May 18, 1918. Serial No. 235,222.
To all whom it may concern Be it known that I, Josnrrr SALOMON, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois,- have invented certain new and useful Improvements in Industrial Chairs, of which the following is a specification.
' My invention relates to chairs and stools,
and particularly to those which are of solid and substantial construction, and designed for the purpose of withstanding severe usage in ofiices, shops,-factories and the .like. To the legs of such a chair, preferably constructed of angle iron, I attach a back which is simple in construction, and which is resilient so as to conform itself to the movements of the occupant. I also provide means by which such back may be securely attached to the legs-of the chair and yet be readily. adjustable in height relatively to the seat.
My invention is illustrated in the drawings, in which- Figure 1 shows a perspective of my improved chair;
Fig. 2 is a section of a cross bar and clamping members on the line 22 of Fig. 1;
Fig. 3 is a section taken on line 3 of Fig. 1.
Describing my invention with reference to the drawings: The chair as shown in Fig. 1 has aseat 1, supported by diverging legs 2, which are attached to a ring 3. The said ring and legs are preferably made of angle iron and are connected by the braces 4. The
back consists of a cross piece 6 and the upright supports 7, which should be made of spring metal and curved outwardly at 8 to clearthe edge of the seat. The back is attached to the rear legs of the chair by means of a clamping device which comprises the cross bar 10, having slots 11, adjacent to its ends. A clamp 12 is provided with a bolt 13, which passes through the slots 11 and so as to be longitudinally adjustable thereon. The remaining portion of the clamping member is formed to embrace the two legs of the chair which support the back, and to also inclose the lower portions of the back supports 7. It will be noted that the shank of the clamp is turned slightly inward to provide a. bearing point at 12'; also that the ends of cross bar 10 are slightly curved toward the leg 2 to provide a bearing point at 10. The longitudinal adjustability of the clamps on the cross bar permits them to conform to the divergence of the legs. By means of the bolts 13 the back may be readily placed at any desired height relatively to the seat and firmly secured in the position desired.
A preferred constructionof the seat and attachment thereof to the supporting legs is illustrated in Fig. 3. The ring 3 has a vertical flange 15 and a horizontal flange 16. The leg 2 is made of angle iron or steel which is flattened for a distance from the upper end corresponding to the inside width of flange 15. The flattened end being thus depressed, a relative projection 17 is provided to receive the lower edge of flange 15, while the end 18 fits to the underside of flan 'e 16. Rivets 19 secure the flattened flanges 0 legs 2 to the vertical flange 15 of ring 3' thus affording a rigid support and secure attachment of the legs to the seat.
I claim: v
1. In a. chair; the combination with two adjacent legs thereof, of a back having uprights, a bar extending across said rear legs, and clamping'member adjustable on said bar, adapted to cooperate with the ends of said bar to clamp said uprights to said legs.
2. In a chair; the combination with two adjacent legs thereof, of a back having spring uprights, a bar extending across said rear legs, clamping members longitudinally adjustable on said bar, and means for causing said clamping members to cooperate with the ends of said bar to clamp said uprights to said'legs.
.3. In a chair; a seat, legs secured thereto and divergent downwardly therefrom, a bar extended between two adjacent legs, clamping members adjustably secured to the ends of said bar, a back, and supports therefor received by said clamping members to secure them to the said adjacent legs.
4:. In a chair; a seat, legs secured thereto and divergent downwardly therefrom, a hack comprising supports extended downwardly to two adjacent legs, a tie-bar extended between said adjacent legs, and clamping members longitudinally adjustable on said bar and co-acting with the ends thereof to clamp the back supports to said legs.
'5. In a. chair; a seat, legs secured thereto and extended downwardly therefrom, a bar extended between two adjacent legs and having the ends turned inwardly to bear on.
flanges of said legs, clamping members having shanks off-set to form points to bear on said bar adjustably secured thereto, aback, and supports therefor received by said clamping members to secure them to the said adjacent legs.
6. In a chair having a seat, legs secured thereto and downwardly divergent therefrom anda. back having uprights; the combination therewith of a tie bar to connect two adjacent legs, members at the ends of said bar cooperating therewith to connect said back uprights to said adjacent legs, and means for longitudinal adjustment of said members on said bars whereby the bar may have vertical adjustment on said legs.
7. In a chair; legs angular in cross section and spread at their upper ends so as to depress the external angles of said legs at the spread portions and cause the portions of said angles below said spread portion to form relatively projecting supports there'- below, a seat resting on said supports, and
means for securing the said ring to the spread portions of said legs.
8. In a chair; legs angular in cross section and spread at their upper ends so as to depress the external angles of the said legs at the spread portions and form relatively projecting supports therebelow, a seat ring provided with a vertical flange having the lower edge resting on said supports, a horizontal flange resting on the ends of said legs, and means for securing said ring to the spread portion of said legs.
9. A leg for metal chairs integrally formed from an angle bar and having an attachment end spread and depressed below the line of the external angle of said bar, whereby the adjacent portion of said external angle provides a support for a seat ring.
In witness whereof, I have hereunto subscribed my name this 16th day of May, 1918. at Chicago, Cook county, Illinois.
JOSEPH SALOMON.
