CAR-SEAT.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed May 8, 1913. Serial No. 766,265.

To all whom it may concern Be it known that I, ALBERT LESLIE LAM- BERT, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in* vented certain new and useful Improvements in Car-Seats, of which the following is a specification.

This invention relates to car-seats and particularly to the portion of such a seat located at the aisle end of the seat including the seat end, the arm-rest and the end-plate to which certain of the operating or supporting mechanism of the seat is secured.

The invention is directed to the provision of an improved construction to be employed at the aisle ends of car-seats, the improvements being of special value in that by the use of them the seat structure is made very rigid and may be made of very attractive design at a manufacturing cost which is comparatively low.

The invention involves the provision of a seat-end consisting of two parallel sheetmetal posts on the upper ends of which an arm-rest is secured. To the lower ends of these posts is secured a metallic end-plate which extends between the posts and has its ends overlapping and secured to the inner sides of the posts at the lower ends thereof. A sheet-metal panel is provided extending between the lower ends of the posts and secured to the adjacent sides thereof, this panel overlying the end-plate between the posts so as to conceal the latter. Each of the posts is preferably made of two sheetmetal plates having their edges flanged and secured together and the inner plate of each post is cut away at its lower end to provide space for the reception of the end-plate of the-seat, thereby making the structure much more compact. This end-plate is secured to the outer plates of the two sheet-metal posts and in order to make the structure rigid and strong at the joints between these parts, suitable metallic stiffeners are applied to the outer plates of the posts in position to coact with the securing means for uniting the posts and the end-plate.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a front view of the seat-end and arm-rest broken away and sectioned in part, F1g. 2 is a section through one of the posts on line 22 of Fig. 1, and Figs. 3 and 4 are horizontal sectional views on lines 33 and H of Fig. 1.'

Referring to these drawings, the seat-end comprises two parallel vertical posts each of which is formed from two sheet- metal plates 5 and 6. Each of these two plates is prov ded with flanges 7 at its lateral edges and slmllar flanges 8 at its upper end so-that the two plates 5 and 6 for a post may be brought together with they flanges of the plate 6 overlapping those of-the plate 5 to produce a hollow post of substantially rectangular cross-section as shown in Fig. 4. With the two parts for a post thus assembled, the coacting flanges 7 are secured together in any sultable manner, as for instance, by welding or brazing. In this manner a sheet-metal post is provided of box section throughout so that it possesses great strength and at the same time is of attractive appearance. The outer plates 6 of the posts may be given such shape as is desired in order that the comcompleted seat-end may present an attract1ve appearance. Also a sheet-metal panel 9 is provided extending between the lower ends of the two posts and secured at its ends to the adjacent faces of the posts. This panel 9 is also pressed into form so as to embody an attractive design. In the drawings, the panel 9 is shown as having its edges flanged inwardly and the flanges 10 at the ends of the panel 9 are secured to the adjacent faces of the posts by welding, brazing or riveting them thereto.

The seat-end consisting of the two posts and the panel 9 extending between them is sired form. Preferably the upper edge of plate 11 is flanged as shown at 12 so as to provide an edge portion adapted to overlie the lower ends of the inner plates 5 of the posts and the flange on the upper edge of the panel 9. The plate 11 is secured to the two vertical posts by means of bolts 13. In

order to permit of the use of metal of comparatively light weight in the posts of the seat-end, stiffening pieces are applied to the posts at the points where these securing devices coaet therewith. These stiffening pieces are shown as consisting of sheet-metal strips 14 of channel-section and they are applied to the posts by having their body portions lying against plates 6 of the posts along the lower ends of those plates projecting below the ends or the plates 5. Two or more spacers 15 are interposed between the endplate 11 and the plates 6 of the two vertical posts in order that these parts will be held at the requisite distance apart. If desired these spacers may be secured to the stiileners 1 1 and the latter may be secured to the plates 6 of the posts before assembling all of the parts in their final form. In either case, however, the bolts 13 are inserted through openings in the plates 6, the stilfeners Ll, the spacers l5 and the endplate 11 and nuts 16 are screwed up on the ends of these bolts so as to secure the parts rigidly together. When the parts are so secured together, the stifl'eners 14 reinforce the plates 6 of the posts so as to prevent distortion thereof and at the same time permit of securing the posts and the parts se cured thereto to the seat-end with such rigidity that danger of the parts becoming loosened or displaced from position is practically eliminated.

An arm-rest is mounted upon the upper ends of the posts. In the present instance, this arm-rest is shown as consisting of an upper portion 17 of wood combined with a lower portion 18 of sheet-metal, these two parts being secured together in any suit-able manner, as for instance, by screws 19. In order to secure the arm-rest upon the upper ends of the posts, I employ bolts 20 passing through openings in the coacting flanges on the upper ends of the parts 5 and 6 of the posts and also through openings in the lower metallic portion 18 of the arm-rest. By means of such boltscoacting with the bottom portion of the arm-rest and the closed upper ends of the posts, the arm-rest and posts may be secured together quite rigidly.

It will be seen that the panel 9 extending between and secured to the lower ends of the posts overlies the portion of the endplate 11 extending between the posts so that the end-plate and other parts of the seat mechanism are concealed by this panel. its a result of this and the shaping of the exterior surfaces of the posts and the panel 9, the seat-end structure may be so made as to present an attractive appearance in addition to possessing great strength and rigidity. Furthermore the structure is of such simplicity as to permit of manufacturing it at comparatively low cost.

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 two parallel posts each formed from two sheetmetal plates secured together at their edges, the inner plates terminating a substantial distance above the lower ends of the outer plates, an end plate extending bet-ween the posts on the inner sides thereof, overlying the lower ends of the inner plates of the posts, means securing the end plate to the outer plates of the posts, and a sheet metal panel secured to the outer plates of the posts and overlying said end plate, substantially as set forth.

2. In a car-seat, the combination of two parallel posts each formed from two sheet metal plates secured together at their edges, a sheet-metal panel having flanged ends, secured to the adjacent sides of the oute plates of said posts near the lower ends thereof, and an end plate extending between and overlapping said posts on the inner side thereof, and secured to said posts, substantially as set forth.

This specification signed and witnessed this 2nd day of May, 1913.

ALBERT LESLIE LAMBERT.
