Constructions, of which the following is a specification.

The present lnvention relates to the con struction' and arrangement'of certain portions of a car seat such as is commonly employed in railway passenger coaches, etc., and deals particularly with'certain portions of the mechanism comprising the means for permittlng the back of the seat to assume a reverse position with respect to the cush on. The objects of the invention are to provide members in the form of rods, which rods will be of the character of a crank and will serve the double function of connecting the mechanism 011 the wall and aisle sides of the seat, so that one side of theback will not move in advance of the other, which would; cause a binding; and to also utilize these rods as an actuating means for the rocker plates.

A further I object of the invention is to provide a connection between these rods and certain links connected to the'back, wh ch will be of a freelyjdetachable character, eliminating'the use of bolts and other similarse'curing means now employed fon'connecting such parts, which jexpedites their assembly.

Afurther object of the invention isto" provide a bearing for these links intherocker plate, jthus insuring "a 7 connection between thes'e'plates which will'not'become loose and thereby result in aloose nd ir'nprop merit onthe part of the back. y

' furtherobject of the invention is toprovide a sifnple means 'forj ourna ling the connettin rods to maintain them in proper relation to the links.

" "Th invention further; consists-"in the features of construction combination of parts hereinafter described and claimed.

Application filed. July 9, 1918; Serial No. 244,066.

In the art to, which the present invention relates, carseats are constructedwith movable backsfwhich can be swung from one edge of the seat cushion to the other, thus reversingthe position oftheseat in accordance with the direction'of movementof the car. i In such constructions, it has'been customary to form a connection between the parts which enables the back to be moved, and whereby all portions of the back Will move in unisoin so that no matter'whether the, force for moving the b ack be applied to the back at the aisle side, thereof or thelwall side thereof, a free and easy'movei rient' will always be maintained. M e I It has been; customary to jointhis connection to the other portions of the, mechanism by means of bolts, nuts, or similar. attaching devices. This, however, is adifiic'ultI'opera tion requiring "considerable e ria ctiti'ide 1n, getting the various openings in line, so that the bolts can readilybe inserted andfthe partsproperly assembledl 7 It has also been cu stoinary'to. attac ng),

comprising a back 8," arms :9 "and "a" cushion 10, all of which mayb'e'of any suitable and desired construction. At the aisleend of theappliance, a plate 11 is employed, sef cured by" suitable. fastening means 12' to the arm; and at the oppo'site'e'nd ofthe se'at is a similar plate '(not shown) attachedtothe wall of the car, which constitutes "the wall plate. The use of the foregoing plates: is well known in car seat constructions;

Both at the wall and aisle sides of the seat are rocker plates; 13 'for the purpose of changing the angular" disposition of the cushionwhen the back ismoved. The use of these rocker plates is well known, and although the particular plate shown in the drawings is deemed to be'new and novel, it does not have any bearing upon the subject matter of the present invention and will not are rods 17, which form aportion-of the 7 subject matter of thepresent invention.

These rods extend from side to side of the seat and are formed with-an offset 18 .located-just outside of the rocker plates, as will be understoodfrom i g. 6," although the offsets may be placed a greater or less dis- ,tance from the rocker plates if desired.

The rods are further formed with a bend 19 and a bend 20 adjacent their ends; and the portion 21 lying between said bends is, in the construction shown, of flattened formation, the function of which will herein-' after appear. The rods terminate in an end 22, about which they turn;

Engaging with these rods are links 23, each of which is pivotally connected to a plate 24 joined to the seat back. The ends of each of these links is in the form of a slotted lug 25,having a slot 26 therein, the Walls of which overlie and engage the flattened portions. 21 of the rods 17; and each of the links is formed with a base 27 which is journaled in a recess 28 formed in the aisle or wall plates, depending upon whether the links on the wall or aisle side are referred to. By this construction, the slotted ends of the links act in the manner of a jaw to engage with the rods in the manner of a wrench, so that when the links are moved, they will, by reason of their connection to the rods, turn the latter. 7

There is a similar arrangement of the plates and links for boththe, wall and aisle sides of the seat, but since they both are exactly similar in nature, only a detailed disclosure of the aisle side has been set forth.

It -will be understood fromthe drawings and the foregoing description that the connection described between the links and rods is of a freely detachablecharacter and does not require the use of'bolts, rivets, or like fastening devices, for the purpose of securing them together, and thereby eliminates the necessity of the careful assembly operation which is required when bolts or similar devicesare used for this purpose.

The rods 17,.extending as they do from the aisle plate to the wall plate of the car seat, form a connection'between the operating parts on the aisle side and the operating parts on the wall side, so that such 'parts are moved completelyfin unison. Therefore,-

when the pressure is applied to move the back, it will make no difference whether the.

opposite side through the medium of the. rods 17; and the seatrwill move in a proper manner to eliminate the binding or jamming which would occur if the aisle side moved" seen that these jaws contact and engage theportions 21 of the arms, and thus there is provided an elongated surface connection between said lugs and the arms, so that the V lugs have a firm and efficient grip upon the rods, which grippage is augmented by the flattening of the" portions 21.

When the.

back is moved, one end of the link 23 iscarried bythe plate 24 and the other end of the link turns about its seat in the recess 28 in the end plate. The links in so turning about their mounting in said recess will swingthe jaws 25 and by the grippage of said jaws on the portion 21 of the rods 17, said rods will be turned. i

These rods are offset as'described, at 18, so that they are of crank formation, and when turned, the portions 29'thereof, which lie in the slots 16 of the rocker plates, will exert a pressure against the walls of the slots 16, causing the'plate to shift inac cordance with the swinging of the back. These rockerplates have-to do with the changing of'the angular disposition of the cushion, as is wellknown in the art.

:The rods as thusformed perform the double function of a connecting part be-; tween the mechanism on the aisle and wall sides of the seat and constitute cranks for the purpose of causing a movement of the mechanism over what, so: far as I 'am aware,

has existed in the. prior art.

By forming the lugs with the boss 27 and:

j ournaling .said boss directly in 'the end plates, a firmand efficient bearing'is providedfor the links, so that they do not become loose, causing a wabblymovement "of the back, which is undesirable, and, moreover, the hollow boss 27 provides a'joiirnal bearing for the end 22 of the rods 17, thus making a very simple and compact mounting for both the rods and the links.

Although the device has been described with considerable particularity, it is not deemed to be limited other than may be by the terms of the appendedclaims. 3 Iclaim: 1. In a car seat, the combination of a movable back, a pivoted link connectedtosaid back, said link being formed with a slot to provide a jaw member thereon, a rod in th form of a crank, said jaw member engaging said rod to turn the same as the link is moved, a cushion, rocker mechanism for changing the angular position of the cushion as the back is moved, and a connection between said rod and rocker mechanism, substantially as described.
