To all whom it may concern: 7

Be it known that 1, JOHN EDWIN KIL- BURN, a citizen of the United States, residing at Philadelphia, in the county of Phila of a. car-seat of this type of an improved construction, the improvements being such that seatand back-cushions of the maximum length can be employed, that the backsupporting member may be set in from the end of the back-cushion, that the back-supporting member will possess ample strength but will be of such size as not to encroach upon the space in rear of the back and obstruct the freedom of entrance to the next seat in the rear, and that the."seat-structure as a whole may be manufactured at comparatively low cost.

The invention involves the provision of a standard for supporting the seatand backcushions which standard'has a horizontallydisposed portion for supporting the seatcushion and a back-supportingarm extending upwardly from the rear end of this member and adapted to support the back-cushion. This upwardly extending member is so formed that it will enter and lie within.

the back-cushion, it being preferably disposed between parallel slats of the cushion which may support rows of springs. In this way the standard may be set in from the end of the seat asfar as is desired; this is of importance in some cases as for instance,

.when the standard is mounted upon or formed integral with a pedestal and it is necessary to set the pedestal in from the end of the seat in order to clear and permit the removal of a trap-door in the floor of the car. The standard for supporting the cushion is preferably formed separately from the pedestal and is of sheet-metal pressed to a particular form so as to afford great strength. The construction of the standard includes the provision of a reinforcing member at the junction of the horizontally disposed member andthe upwardly-extending arm, for it is at this polnt that the drawings in which greatest strain is thrown on the standard and at this point also that small size is necessary in order that the arm will not objectionably limit the freedom of entrance to the space directly in rear of the seat. The upwardly extending arm which supports the back-cushion is hollow and of rectangular cross-section as in this way ample strength is secured. Whetherthe standard for supporting the cushions be formed'in- .tegral with the. support therefor which is mounted on the floor of the car or is formed separately and mounted on a supporting pedestal, the horizontally-disposed member of the standard extends under the seatcushion, the end of which preferably projects beyond the standard. In this way the cushion may be made of maximum length. Preferably, the end of the seat-cushion extends slightly beyond the end of the backcushion, so that not only is the seat-cushion made of-maximum length but also the aisle I at the end ofthe seat is made of slightly greater width above the level of the seatcushion where greater width is necessary.

When a separate pedestal is employed for supporting the standard this is preferably made from sheet-metal by pressing pieces thereof into the desired configuration' In accordance with the invention this pedestal is made in a particular manner whereby great strength is obtained in astructure of marked simplicity. j v

Referring to these drawings, 10 indicates the pedestal on the upper end of which 'is mounted a standard having a horizontallydisposed member 11 and an upwardly extending back-supporting arm 12. This member 11 supports the seat-cushion 13 and the back-cushion 14- of the seat is secured upon the arm 12. The construction of the standard will be understood by reference to Figs. 4, 7, 8 and 9. The horizontally-disposed member 11 is formed of sheet-metal and is provided with flanges 15 at its edges disposed at a right angle to the body-portion of the standard so as to stiffen the construction and give greater strength. A plurality of gussets'or braces 16 are also provided for bracing one or both of these flanges relatively to the body-portion of the standard. The upper flange 15 is provided with a'pin 17 adapted to be received in an opening in the frame of the seat-cushion 13.

' The upwardly extending arm 12 is formed integral with the horizontally-disposed member 11; furthermore, the standard is reinforced at the junction of the members 11 and 12 in such a manner as to provide great strength at this joint without unduly enlarging the dimensions of the standard.

The arm 12'is of rectangular cross-section, shown in Fig. 9, and preferably it tapers slightly toward its upper end. The rectangular construction is obtained by providin'g flanges 18 upon the strip from which the arm 12 is formed and then securing a sheet-metal plate 19 to theseflanges. The ercss ectiona1 shape of the standard at the junction of the two members thereof is shown in Fig. 8 wherein it will be seen that at thispoint the standard is of box-section. The standard as thus constructed has the back-cushion let secured thereto with the arm 12 extending within the cushion. For this purpose the frame of the cushion is provided with a groove to receive the arm 12 and the major portion of the arm is arranged to lie between two adjacent slats of the cushion which support rows of springs. Referring to Figs. 5 and 6, it will be seen that the baclecushion 14L is provided with a rectangular frame 20 consisting of four wooden frame-members secured together at their ends. A plurality of slats 21 extending' acrossthis frame are secured at their ends to opposite frame-members. Each of these slats supports a row of springs 22 and a flat spring 23 extends over the springs of a roW' and is secured to the upper ends thereof. The covering material of the cushion overlies and is yieldingly supported by these fiat springs. The bottom fra1nemember of the back-cushion is provided with a groove, shown at 24: in Fig. 6, this groove being located in alinement with a space between two adjacent slats 21. The arm '12 of the standard is inserted into this slot with the upper portion thereof lying between the slats 21 in the manner shown in Figs. 5 and 6 and is then secured to the back-cushion by screws 25 passing through the flanges "18 and entering the bottom frame-member and the slats 21. The standard is then mounted upon the pedestal 10. The construction which I prefer to employ in this pedestal is illustrated in Figs. 1, 2 and 3. The pedestal has a base portion pref erably of oval cross-section and pressed from a single piece of sheet-1netal. This base portion flares at its lower end into a flange which is secured to the floor. On the upper end of this base-portion is secured a top-piece'26 also pressed into form from a single piece of sheet-metal and so shaped as to provide forwardly and rearwardly extending arms 27. These arms are of U shape cross-section and are open on the upper sides thereof. Into this open side of the top-piece 26, a plate of sheet-metal 27 is inserted, this plate being first cut out to a configuration corresponding to the upper side of the top-piece 26. Plate 27 having been thus inserted, as shown in Fig. 3, it is secured to the abutting walls of the toppiece 26 by welding, brazing or a similar operation, The lower contracted end of the top-piece 26 is secured to the base of the pedestal preferably by welding their abutting edges together as indicated by the dot and dash line. A pedestal constructed in this manner is of simple design and may be manufactured at low cost and it possesses great strength as compared with pedestals of this character heretofore employed. The standard 11 is secured upon the upper end of the pedestal by bolts 28 passing through openings formed in the arms of the pedestal and in the lower flange 15 of the standard. As the strain of the bolts is taken by the side walls of the arms of the pedestal, that is, by metal set on edge, no reinforcement is required within the arms of the pedestal. The standard supporting the two cushions of the seat is of such great strength by reason of the use of sheet-metal therein the employment of a box-section in the arm 12 and the provision of a reinforce at the angle in the standard that danger ofbreakage of the arm under the strains to which it is subjected in use, is eliminated. By reference to Fig. 1, it will be seen that this strength is secured without so increasing the size of the standard at and adjacent to the angle therein as would obstruct the freedom of entrance to the seat directly in rear. When the back-cushion is mounted upon the standard, the latter lies within the cushion and this permits of the use of a back-supporting arm 12 in a seat of this type which arm is hollow and of rectangular cross-section. If such an arm were used at the end of the back-cushion andexterior thereto it would require an undesirable reduction in the length of the back-cushion, but with the construction shown, the back-supporting arm 12 lies in space which, or most of which, would not otherwise be utilized.

A further advantage incident to the use of the construction illustrated is that the standard can be set in from the ends of the backand seat-cushions as far as is desirable. This is of importance in connection with standards which are mounted adjacent to trap doors in the floor of the car; in such case, the standard and the pedestal on which it is mounted may be set in so far that the pedestal will clear the edge of the trap door. Furthermore, the construction illustrated permits of obtaining the maximum length in the seatand back-cushions.

The construction of the back-cushion herein shown and described may be modi fied by omitting the springs which yieldingly sustain the surface material of the cushion, as is done in some cases. When no springs are employed, the back-arm may be secured to the frame of the back-cushion and, if desired, two slats may be incorporated in the frame of the cushion, which slats do not support springs but have the back-arm secured thereto.

Having described my invention, what I claim as new therein and desire to secure by Letters Patent of the United States is:

1. In a car-seat, the combination of a horizontally disposed cushion-supporting member extending from front to rear, adapted to receive a seat-cushion upon its upper surface, a back-supporting arm extending upwardly from the rear end of said member, and a back-cushion having a frame and a plurality of vertical slats intermediate the ends of the frame, said cushion being mount- 7 ed upon said arm with the arm extending between and secured to two of said slats, substantially as set forth.

2.131 a car-seat, the combination of a pair of horizontally disposed seat-cushion supporting members extending from front to rear, adapted to receive an overlapping seatcushion upon their upper surfaces, back-supporting arms extending upwardly from the rear ends of said members, and a backcushion having a frame and a plurality of vertical slats intermediate the ends of the frame, said cushion being mounted upon' said arms with the arms extending within the frame of the cushion intermediate the ends thereof, and each lying between two of said slats, and plates secured to the rear surfaces of said arms and to the rear surfaces of the adjacent slats, substantially as set forth.

3. In a'canseat the combination of a horizontally disposed cushion-supporting member extending from front to rear, adapted to receive a seat-cushion upon its upper surface, a back-supporting arm extending upwardly from the rear end of said member, and having flanges extending laterally from the rear portion thereof, and a back-cushion having a frame and a plurality of vertical slats intermediate the ends of the frame, said cushion being mounted upon said arm with the arm lying in a slot inv the frame and between two of said slats, and said flanges secured to the adjacent slats, sub stantially as set forth.

4. The combination, in a car-seat, of a back-cushion having a frame and a plurality of vertical spring-supporting slats extending across said frame and secured at their ends thereto, the bottom frame-member having a vertical groove therein on the rear side thereof, and a back-supporting arm lying in said groove and between two of said slats, said arm having laterally-extending flanges at the rear edge thereof, lying against and secured to the rear surfaces of the adjacent slats, substantially as set forth.
