CAR SEAT.

Application filed March 18, 1921. Serial No. 453,459.

To all whom it may concern:

Be it known that I, ALBERT L. Listener, a cltlzen of the United States, reslding at Narbeth, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Car Seats, of which thefollowing is a specifica-, j the line 3.3 of F 1g. 2, and Fig. 4: 1s a hor My invention relates to reversible carseats 1 tion.

for railway carriages and the like and one of the objects of this invention is to provide for this typeof seat an improved seat end which posseses great strength, which can be manufactured at small cost, which is arranged to facilitate the application thereto of the seat-reversing mechanism, and one which permits of the concealment or covering of the parts of the seat which are attached thereto so as not to be in the way of a passenger moving down the aisle.

A further object of my invention applies particularly to thewell known reversible car seat construction wherein the back standards carry rollers mounted to travel back and forth in channel tracks carried on the seat'ends. Due to the vibration of the mov: ing train these rollers are aptto be joggled about between the upper and lower members of the channel track, particularly when the seat is unoccupied,-and such joggling occasions considerable noise and rattle. The particular object involved is to provide means to prevent the rollers from joggling or rattling about in the channel track and thus to eliminate the objectionable noise and rattle above referred to.

Other objects of this invention will be in.

part obvious andin part pointed out hereinafter. i r

I will now describe a reversible car seat of a well known type, confining my descrip- 7 a side elevation of a reversible car seat,em-

bodying my invention, the back being shown in one of its extreme positions; Fig. 2 is a plan view of the end plate of the car seat built according to my invention" and. inriudes, diagrammatically, the rollers carried by the back standard and my invention applied thereto; Fig. 3 is a. vertical section of my improved end plate taken on Similar reference characters designate similar parts throughout the several views of the drawings.

Referring to the drawings,the reference,

character 1 represents theusual aisle pedestal, 2 and 2 the cross members, supported on the aisle pedestal and the wall support for the seat, 3 the seat cushion (shown in dotted lines) supported on cross members 2 and 2, 4 the usual back provided on its edges with metallic standards, one of which is shown at o, carrying at its lower end rollers 6. and 7, which are mounted to be moved back and forth in curved channel tracks'carried on the seat ends, one of which is shown at 8, of the car seat, inthe well known manner.

Since my invention relates to the novel and improved end plate for the seat, sometimes called seat end, the seat end will now be described in detail. In accordance with my invention the seat end 8 is formed from. a single pieceof sheet metal of a weight and strength sufficient ,to give the required. strength. The channel track for the rollers 6 and '7 is formed on the inside surfaceof the seat end by pressingor otherwise shaping the piece of sheet metal in such away that it will present two parallel, spaced folds or flanges 9 and 10, extending inwardly and longitudinally acrossthe seatend and forming a channel track, comprising respectively lower track member 9 and upper track member 10, as shown. At each extremity of these track members a portion of the piece of sheet metal. is pressed inwardly to provide a flange 11 forming a stop for the rollers 6 and 7 when they reach the extremities of the track. Heretofore ithasbeen customary to form the channel track separately from the seat end and'to secure it to the inner tace of the seat end with rivets or by weld- 7 integraletherewith, considerable saving ot'expense and time-is effected in the manufacture of the seat end and considerable saving in naterial isefiiected, and at the same time space-fat the ends ofthe seat isconserved.

' As a further improvement. in seat end construction, the end plate may be formed to present integral portions suitable for the attachment thereto of parts of the seat mechanism. One of these portions, as illustrated, co'mprises'a boss12 below the channel'track formed integrally on the seat end,

at its centre, and has a perfoi ation 13 adapted to receive the "usual bushing 13. for

one end of a rocker rod. Boss 12 provides on the exterior of the scat end a-pocket of such depth that the end of the bushing 13' or the rocker rod, or aretainin'g nut thereon will not extend beyond the outer surface bolted thereto, as at 1 8, and to the cross member 2, as at 20, in the usual manner,

with the bolt head or nut on the bolt 18 toward the outside of the seat end seated in the pocket with no part extending beyond the outer surface thereof.

7 Thus it is apparent that a seat end of the above configlllltttlOll and construction maintains all the arts of the seat mechanism which are connectedthereto, out of the way of'a passenger traveling down the aisle and so masks these parts that they are not likely to catch desired.

against a grip carried by a. passenger nor to catch into and tear a passengers clothing. An nwardly extending peripheral flange 21 may be'formed about the seat end, and

a cover plate 22 provided with a correspondinglnwardly extending flange 23, may be applied to the outside of the seat endwith flange 23' overlapping flange 21, to further mask the parts of the seatmechanisni which are attached to the seat end for'the'pu'rpose The cover plate may be joined to the seat end by welding or the like and in this manner a smoothflat surface may be any "suitable design supplied thereto.

provided for the outside of the seat end, or The welding operation may be dispensed with by bending or pressing the flange 23 of cover plate 22 about the inner edge of flange 21 as shown at 24. vAt the extremities of the channel track the end plate and the flange 28 of the cover plate 22 may be brought together by continuing flange 11 of the end plate at right angles and until it abuts flange 23 as at 2 1. The surface of the seat end, even without the cover plate, is sufficiently flat for direct attachment to the car wall at the wall side of the seat.

drop into depression 26.

the full distance between the rollers when they are in normal position on the track, as is shown by dott-edllines in Fig. 2. Each end of this block 25 presents a sloping surface receding upwardly from the, adjacent roller. At each end of the lower channel track member? is'tormed a depression 26 and 26, respectively, into which the outside roller is adapted to fall as the roller approaches the end of the channel track and the seat reaches either extreme position. [is the outside roller drops into a depression the inner roller will ride upwards on the adjacent surface of member 25 so as to be firmly held against the upper channel track member 10, and while the seat is in an extreme position the inner roller will be so firmly held again t the'upper channel track that it will be prevented from vibrating or rattling, and 11121 not occasion objectionable noise by so doing.

In operation it has been found that the provision of member 25 in no way retards or hinders the easy reciprocation oi theback in the usual manner. As the back appreaches one extreme position, for instance,

the position illustrated in Figs. 1 and 2,

roller 7 will roll into depression 26 and member 25 will thereby be held against further horizontal movement, and as roller 7 drops further into the depression, roller 6 will ride up on the surface 27 of member 25 until it is firmly pressed against the upper channel track member 10, as at 28 by the weight of the back which causes roller 7 to Similarly when the back is reversed, roller 6 will drop into depression 26 and roller 7 will be held against vibratory movement in the channel track on account of its having ridden upward on surglace 29 of member 25 and is being firmly pressed against the upper; channel track member 10 by the weight of the back which causes roller 6 to sink into depression 26.

It is believed that applicants invention relating to means for avoiding the objectionable noise as above described is broadly new, and since many changes'c'ould be made inthe above construction and many apparently widely different embodiments o f'this invention may be made witho'ut'departing from the scope thereof, it is intended that all matter contained iir'the aboved escription or shown in the accompanying drawings shall be interpreted as illustrative and notin a limiting sense. i
