Application filed May 19, 1905. Serial No. 261,181.

To (LU whom it may concern:

.Be it known that I, EDWARD G. Bonn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Car- Seats, of which the following is a specificatron.

The object of the present invention is to provide a seat,'preferably of the walk-over type, in which the movable parts whereby the back is supported and guided in its reversal movement'from one facing direction be of great strength and durability, the several'elements thereofbeing positively mechanically interrelated, so as to avoid loose connections and permitthe back to be reversed with a uniform and continuous movement from one edge of the seatcushion to the other.

In carrying out the invention I employ a back, preferably of the walk-over ty e, having at each end a depending arm to w 'ch are secured the outer ends of two levers, the in.- ner ends whereof are pivoted to the frameplate'preferably in a vertical plane. Said levers are provided near. the pivotal points at which they are connected to the frame with ears,'and extending between and connecting these is a link so arranged and o crating as to' synchronize the movement 0 the inner ends of said levers. Coacting with said levers or with the back-arrns are suitable stops whereby the movement of the seat-back m h one or the other direction is determined. Also, if desired, a shifting seat-cushion may be employed mounted upon rockers connected with the back movement, so that the reversal of the back will through such connectionefi'ect the shifting of such rockers and the seat-cushion carried thereby.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a central section of a car-seat constructed in accordance with my invention,

the cushion-carrying rockers being removed and the back and seat cushions being shown in-dotted lines. Fig. 2 is a view similar to Fig. 1, but showing the back in the opposite position and in addition one of the cushionrockers and mechanism for actuating the same. Fig. 3 is an enlarged detail view illus trating the connection between the levers car .tends a screw (1 rying the back-supporting arms. Fig. 4-is a front elevation, partly in section; and Fig. 5 is an enlarged sectional detail on the line 5 5, Fi 2.

Referrin to the drawings, in which similar letters denote corresponding parts, I premise with the statement that inasmuch as the mechanism at both ends of the seat may be of similar construction I shall describe that at one end of the seat only- The frame includes the support A, the end plate B carried thereby, and the connecting rails or sills 6, upon which are mounted the rockers b, carrying the seat-cushion b Said rockers b have sliding movement in runs or ways If, formed in said sills or connectingrails by C, designates the seat-back, here shown as of the reversible type and carried detachably or otherwise upon a back-arm c at each end.

Said back-arm 0 depends below the lower ed e of the seat-back and is preferably provi ed with a shoulder c, the back-cushion in practice being of less width than the seatcushion, outside which the back-arms c operate.

D E designate levers pivoted at the points d e to the back-arms c in the longitude thereof and at their other ends to the end plate B of the frame. The preferred method of pivoting the inner ends of each of said levers 1s shown in detail inFigs. 4 and 5. The pivot of the upper lever D comprises the studd, aving the head d said stud projecting through an orifice in the end plate B. d designates a disk or Washer througl'i whlch exengaging with a threaded orifice in the stud d and also, if desired, in the head a of said stud. Said stud 1 furnishes a wearing-surface of considerable size and adequate strength for coaction with the lever D. Thelower lever E'is here shown as pivoted upon the tie-rod F, extending be tween and connecting the two end plates B of the seatframe. Adjacent to each of said end plates said tie-rod is square in cross-secs tion', as shown at f, to coact with the correspondingly-shapedoriflce near the inner end of thelower lever E and with an orifice also correspondingly sha fed in a plate f having socket f Sai plate fmeans of rivetsf to the inner face of the lever E. The movement of said lever, thereis secured, by

- There are no loose 40 out of adjustment fore, is transmitted to said tie-rod extreme end (round in cross-sectionl of said tie-rod is carried in a suitable bearing-formed in the headed stud f, the head f whereof may be flattened out over the washer ffl-aiid both may be countersunk in the end plate B, as may also the head d of the stud (1. Such countersinking and in addition the paneling of said end plate, as shown in Figs. 4 and 5, 1o contribute-strength thereto, said end plate being preferably made of pressed steel.

The lever D, is rovided with the angularly-disposed ear (i about a right angle to the longitude of its respecti'velever 1) E. Coacting with these ears is a link g, preferably pivoted to one of v said ears and having slot-and-pin connection with the other. In: the drawings I have illustrated said link 9 as having pivotal connection at g with the ear G, its other end beingprovided with a pin or stud g coacting with the slot 9 formed in the ear G, said pin or 2 5 stud'being preferably provided with. the head g Preferably said pin or stud 9 and its coacting slot g will be of ample size to reduce the effect of wear.

It will at once be seen that by means of the 0 construction herein described the levers D E,

fixedly pivoted at their outer ends in the longitudeof the back-arm c and at their inner ,nds to the end plate B, are positively and mechanically correlated not only in their ulti- 3 5 mate positions corresponding with the two facing directions of the seat-back, but also at all times during the movement of such seatback from one of such positions to the other.

arts to wear or be thrown of the mechanism, and lost motion of the back is avoided, the movement thereof from one facing direction to the otherv being smooth and continuous and the inclination 1; automatically effected as part of such movement through the guiding effect of the levers D E. Moreover, the coaction between the inner ends of said levers is substantially uniform during the entire throw of the back from one iposition to the other, there being no possib ty eitherof the evil of dead-centers or of lost or jerky movement in-the operation of reversal.

all-car-seat structures it is essential that 5 a suitable stop device be employed to limit the movement of the back in either'direction,

such stop devices coacting either with'the back-supporting arms or with the levers connected, therewith. To secure adequate 66- strength and also to dead'en impact, I pre er to em 10 the stops shown in the drawings, and w ic .consists each of a cup-shaped re ceptacle H, having a flange h, whereby said cup may be secured by rivets h to the-inner face-of the end plate B. Within said cup I and the lever E with the similarlyrdisposed ear G, each of these ears t5 being in the present instance arranged at uring continued operation place a block b of wood or of several connected thicknesses of leather or other material 1norder that when the up er lever D coacts therewith the shock of impact may be reduced to a minimum. Any desired provision may be made for shifting the seat-cushion and its supportingrockers by the reversal of the bac The provision of this character illustrated in the drawings comprises an. arm I, keyed or other- "wise secured upon the tie-rod F at either end of the seat and carrying" a pin 11. coacting with a slot 2'', formed in' the rocker b. This for-ms no part of the present invention, the essential feature whereof resides in the mechanism for connecting and correlating the inner ends of the levers D E in the manner and for the urpose herein set forth.

aving now described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

1. In a seat, the combination with a frame, a back and a back-supporting arm, of two levers pivoted to said arm in the longitude thereof and at their other ends to said frame,
