BACK-SUPPORTING STANDARD FOR CAR-SEATS.

Application filed August 10, 1915.

To all whom t may concern:

Be it known that I, RICHARD B. MARSH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State oi Pennsylvania, have invented certain new and useful Improvements in BaclrStippo1'ting Standards for Car-Seats, of which the following is a specification.

My invention relates to standards by which the backs of railway car-seats of the walk-over type are supported.

By my invention, standards are made of pressed steel in two pieces which are formed up and welded together; the outer piece overlies the inner at the lower portion of the standard, and extends above the inner at the offset portion formed in both. The oli'set portion of the outer piece has a projection on each side, `formed over and welded to the offset portion of the inner piece, to make a box formation at the oiifset of the standard,the offset being provided to enable the standard to extend around the end of the car-seat, which is of a length greater than that of the back. By this means a very strong construction is provided, combined with light weight. The construction illustrated herewith is also provided with a pivot-pin integral with or secured to a box construction secured to the lower end of the standard, to enable the pivot-pin to extend some distance beneath the seat, as described in the application of Clarence L. Thompson, Serial No. 50,7 22, filed Sept. 15, 1915, the box construction being secured to the inner piece or sheet of the standard. Rollers adapted to travel on the channel .track of an end-plate, when the back is reversed, are mounted on pins extending into the standard on the side opposite to the pivot-pin, below an inwardly extending offset, formed by contacting portions of both sheets or pieces. My invention, however, is not limited in its applicability to a car-seat movement of the character described in the said rThompson application, but in its essential form may be used with any car-seat to which a steel standard may be adapted.

In order that a clearer understanding of my invention may be had, attention is hereby directed to the accompanying drawings, forming part of this application, and illustrating certain embodiments of my invention.

In the drawings, Figure 1 is an end ele- Specification of Letters Patent.

vation of a ear-seat and back provided with my improved standard; Fig. 2 is an enlarged front elevation of the standard; Fig. 3 1s a vertical section on line 3-3 of Fig. 2; Figs. l and 5 are transverse sections taken respectively on lines 4. l and 5-5 of Fig. 2; and Fig. 6 is a section on line 6-6 of Fig. 3.

Referring to the drawings, the standard represented generally by the reference character 1 is secured to one end oi' the back cushion 2, the rollers 3 carried by the standard being mounted on the channel-tracl 4- of the end-plate 5, either the aisle or wall plate, and movable thereover as the back is reversed. The seating angle of the seat 6 is reversed by connection between the stands, one at each end of the back and the rockers 7 by which the seat is supported, such a connection being established, for eX- ample, by the engagement of the pivot-pin 8 on each standard within a slot of the lever or connection 9, having an eccentric connec` tion with the rocker, as described, in said Thompson application.

Each standard comprises outer and inner sheets of pressed steel, 10 and 11, the sheets respectively being bent outwardly or offset, as shown at 12 and 13. The outer sheet 10 terminates a short distance above the oifset portion in a vertical portion 14E, while the inner sheet or piece extends upwardly a considerable distance, asv shown at 15, to form the arm which is secured to the end of the baclccushion 2. The offset portion 12, 13, of the standard, is provided to enable the standard to pass around the upper edge of the seat 6. Beneath the seat, the sheets 10 and 11 may be bent inwardly a slight distance, as shown at 16 and 17, to form a shoulder beneath which the rollers 3 are mounted, the pins on which the rollers are mounted extending through the vertical portions 18 and 19 of sheets 10 and 11, below the shoulder 16, 17.

The vertical portions of the two sheets below the ol'set 12, 13, and also below the` shoulder 16, 17, are welded in contact with each other, the vertical upper end portion of sheet 10, above offset 12, also beingwelded to the upwardly extending portion 15 of sheet 11. The o'set portion 12 of sheet 10 is 'formed with projections on each side, which are formed over as shown at 20 and welded to the edges of offset portion 18 of sheet 11 to make a 'box formation at` the offset. The pivot-pin 8 extends inwardly from the web 21 of the channel or box-formation member 22, the inner flanges 23 of which are secured to the portion 19 of sheet 11 beneath shoulder 17.

Upwardly extending arm of sheet 1() has its side edges bent inwardly as shown at24, this armpreferablybeing given an Yarched formation,r as shown in Fig. 5, for

'the purpose of strengthening the same. Arm 15 p is f secured by screws, extending through ysorew-lioles in the ari'n 15, into the end of theseat-cushion. A reinforcing channel member 26 Amay be secured on member 15, inside fthe edge flanges thereof, to stiffen y'the Y same.

It is obvious that theconstruction de- "scribed strong, light in weight andV ecoiio-ini'calt'omanufact'ureQtheprovision of the vspz'rcedpffset members 12 Aand =13, together "with the sideportions lof offset vnieniber 12, :welded to member 13, effecting astrong `and rigid box formation at the offset, `at

which point the greatest strains are encountered theY standard. It should lbe understood thatthe standard is applicable for use y with 'various types of seats, and that the design and Vproportions ofthe offsetwill vary in accordance with the Construction 'of the seat;

,fHaving now particularly described my invention, what I claim and desire to proteet by Ije'tters Patent is as follows:

1..In a back-supporting standard, the

combination of a sheet of metal pressed to shape with an upper portion having screwho'les therethrough for attachment to a seatback, a horizontally offset portion, and 4a lower verticalportionbelow the oifset portion, and a second sheet of metal having a Alower vertical portion welded tothe lower vertical portion 'of said first sheet, an olfset portion spaced from the said` first offset portion and a short vertical portion above 'Contact and offset portions between said parallel portions, substantially parallel but spaced apart, oneof said oii'set portions having side portions formed over and welded to fsjaid other offset portion to forni a closed box-'sectiom said offset portions being adapte'dfto permitsaid standard to extend around 'the lend of a projecting seat-cushion, substantially as set forth.

3. In -a back-supporting standard, the combination of a sheet of nietal pressed to shape -with an upper portion having screwlioles therethrough for attachment to a seatback, a horizontally offset portion, and a lower vertical portion below the offset portion, and-a second sheet of metal having a lower vertical portion welded to the lower vertical portion ofvsaid first sheet, an offset portion spaced from the said lirst olfset por- "tion anda short vertical portion above said offset portion weldedto the upper -portion of said first sheet, said second offset portion hai/'ing side projections formed over and welded to said first oli'set portion, the lower vertical vportions-of said sheets being bent inwardly, adjacent their lower ends, to

forni a shoulder, and thence downwardly in Contact to their lower ends and rollers ymounted beneath said shoulder, substan- Itially as set forth.
