OF PHILADELPHIA, PENNSYL- METAL COMPANY, OF PHILADEL- PHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

CAR-SEAT., j

.To r/,ZZ whom, t mel/y concern:

Be it known that we,- EDWARD G. BUDD and CHARLES A. CoND, both citizens ofthe United States and both residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Car-Seats, (Case C,) of, which the following is a specification. i

The object of the present invention is to provide a car-seat of the reversible type employing referably a walk-over back reversible om one edge of the seat-cushion to the other, such back being supported by means of the'Seat-frame and guided by means of connections between the same and said seat-frame, so as to automatically effect the proper inclination of the back in its movement of reversal.

A further object is to provide such structure with a supporting and guiding mechanism comprising parts so correlated as to insure positive and reliable coaction in the operation of said mechanism due to the reversal of theseat-back from one facing direction to lthe other.

In carrying out the invention we employ at one or both ends of the structure a sectional frame, preferably of pressed steel, upon which are secured the connecting rails or sills for the seat-rockers and an end plate upon which are 'movably Supported levers coacting with Ithe back or with an arm depending therefrom to afford adequate sup-- port for said back. Carried also plate, preferably upon a revoluble tie-rod extending therefrom to the other end plate, are stationary pinions, with which formed on guide-bars whose other ends are pivotedto said back or to an appurtenance thereof. In the movement of the seat-back from one to theother facing 'direction the weight thereof may be borne either wholly or partly by the bac -supporting levers, and

by the coaction of said pinions with said racks the same is given its proper inclination .in either of the ultimate directions to which.

the backmay be moved.

The invention is illustrated in panying drawings, in which* igure 1 isa central cross-section of a carseat embodying our improvement, the back the accom- Specication of Letters Patent. Application nea may 25, 1905. seau No. 262,190.

Fig. A2 is an enlarged central vertical section of a portion of the mechanism illustrated in Fig. 1, the back-supporting arms bein midway between their two operative posltions, and therefore vertically dlsposed. Fig. 3 is an enlarged cross-section on the line 3 3, Fig. 1. Fig. 4 is an enlarged detail illustrating a portion of the back-supporting arm at lone or Fig. 5 is a plan view both ends of theseat. illustrating the sectional supporting fixture similar view illusor pedestal. Fig. 6 is a trating one of the feet of said fixture. Fig. 7 is a section on the line 7 7, Fig. 6 and Fig. 8 is a similar section on the line 8 8, Fig. 6. leferring to the drawings, in which similar letters denote corresponding parts, A designates .the supporting fixture or pedestal, of which there may be but one, located at the aisle end of the seat, (the inner end of the Seat mechanism being mounted -upon the .carwall,) or two, as desired. As here shown,

this fixture or pedestal is formed in two secf tions a a of pressed or stamped sheet-Steel. The adjacent edges of these sections may be overlapped and riveted or otherwise secured together, or such edges may be inwardly flanged and secured to an intermediate tiepiece, as clearly shown in Fig. 5. The u per portion of said fixture or pedestal is forlied 2 at a2 a3, one or both of such portions being provided with a flan e a4 or a5, adapted to support the T-iron sill or connectin -rail a", which may be secured to one or botlai of said flanges by the yokes a7, plates a8, and nuts a9.

G designates a footfor each of the fixture- 9o sections, the same being preferably of malleable iron. Said foot is preferablyhollow and provided with the ledge ga and the raised portion g, of such size as to snugly fit Within the end of the leg of the fixture, as shown in section in Fig. 1. Said foot is also provided with orifices g5, cored down therethrough to receive tangs g", preferably formed integral l with and extending downwardly from the fixture-leg. Said tangs after being assed into Said orifices are pressedoutwar ly, as Shown in Fi 1, to effect a firm union with said foot. sired, be riveted in position as shown at gl.

Mounted in suitable rocker-runs in`the 5 sills or connecting-'rails a are rockers B, supporting the cushion-frame C. Said cushionframe and its rockers may be stationary or may have lateral shifting movement governed by the reversal of the back, as hereinafter 1o described more in detail. We shall-describe the seat supporting and reversing mechanism at but one endv of the seatfor instance, the aisle may be duplicated at the otherfor 1nstance, the wall end-or such mechanism employed at the latter end as not to interferJ with the operation of that at the Aaisle en D designatesan end plate forming part of zo the seat-frame and secured to the supporting ixture or pedestal ori to the sills or connect- 'ing-rails in any suitable vmannen Carried by said end plate is a trunnion E, a part whereof, e, is preferably square in cross-section, adapting it tocoact with and'securely hold a pinion e. On one side of said part e (to the left in Fig. 2) said trunnion is circumferentially recessed at e, and beyond that it is provided with anannular extension e, go engaging with the end plate D. Outside said end plate said trunnion is provided with a washer e4, over which the head e5 of said trunnion is crimped or otherwi'seexpanded to hold said trunnon in position.V Within 3 5 said trunnon E is .journaled the end of the tie-rod F, extending between and connecting A the end plates at both ends of the seat, and secured to said tie-rod in any suitable manner-as, for instance, by a pin or key-is a 4o block f, carrying a pin f projecting inwardly toward the center of the seat and coacting with arecess f 2, formed upon the rocker B. As will realdily be seen, the movement of said tie-rod involves also the movement of said block f and pin f', and said pin coacting with said recess transmits sliding movement in lateral direction to the rocker B, and therefore to the seat-cushion C, supported thereby. It will be understood that said 5o trunnion E is rigidly secured to the end plate D and that, therefore, neither said trunnion nor the pinion e', carried thereby, is moved by the reversal of either the seat I back or cushion. G designates the seat-back, here shown as of the walk-over type and provided with` an edge-socket with which engages a backarm g', the lower end whereof isprovided with a head g2.

H' designates a back-supporting lever pivoted at h to' the head g2 in a position corresponding with the longitudinal center of the back-arm g and at its other end to the seat-frame. Said backsupporting lever H '65 is preferably formed in two parts h h2, as

end--since this 'said pinion e. sheaves formed integral wit orsecured to shown in Figs. 2 and 4, riveted or otherwise secured together at their ends, as shown at h3, and interlnediate of their ends, as shown at h4. It desired, however, the upper ends of the sections may be slightly separated, so as to extend Aon either side of the head g2, the pivot extending through said head. Adjacent to its oint of coaction with the seat-frame the sectlons h h2 of said back -supporting lever H are se arated, as shown in the figures last name ,extending on either'. side of the pinion e', the section h being provided with an orifice through which thetrunnion E extends and .the section h-Z being provided with a hub h5, through which extends the squared tie-rod F. Eachof said sections h h2 of said hack-supporting lever H is provided with laterally-extending ears h 71,7, one on either side of the pivotal point of said arm, and in addition said members are provided with lips h, of such width or inward extension from said lparts as to permit coaction of said lips, as s own in detail in Fig. 4this construction permitting the housing between saidparts h h2 of the pinion ve and of the racks coacting therewith, as presently described. I I designate ide-racks coacting with the back and with said pinion e. Each of said gnid e-racks is pivoted at its ulper end to the head g2, depending from t e hack-arm g', the pivotal points bein lr on either side ofthe pivotal point h and arranged in a direction at a right angle to the longitude of said back-arm g. The adjacent edges of said 'de-racks I I .are toothed, as shown-at fi., t e teeth thereof'coacting with i2 'i3 desi ate studs or the member h of the back-supporting lever H and coacting with said guide-racks to maintain the same in coaction with said Any suitable stop may be employed for determining the extreme movement of the reversible back G. In the present instance we have shown the end plate D as provided with angular forward and rear edges d d and, secured-to these, stops d2, so arranged as to coact with the lower edge of the head g2 when said head is' in either of its two ultimate positions. If desired, the angularlyshaped edges d d of the end plate D may be utilized for the attachment of a cover-plate (not shown) llying parallel with the plate D, the mechanism above described whereby the back is supported and guided in its movement from oneposition to the other being arranged between such cover-plate and the plate D. This, however, is not regarded as essential in view of the fact that the pinion e and its coacting guide-racks I I are covered almost wholly and adequately protected by the inner section h2 of the backsupporting lever H.

said head and A `through a section of said armon each side of IIO being the same in eitherof substantially as` described.

back-supporting levers H carry the weight .of l

p efiaes lAs will be readily understood, the sectional theseat-back in-its movement of reversal from one facing direction to the other and are well adapted to meet this demand upon them by reason of their sectional construction, adequate strength being furnished thereby. As the back is so moved the guide-racks I I are bron ht into coaction with the pinion-e', so that uring such movement this coaction -results in changing the inclinationV of the back, such inclination the ultimate positions of such back. This -coaction between said lpinion. and the guide-racks isa 4f positive. coaction,

there being no lost motion, and therefore the movement ofthe back from onefacing direction to' the other is smooth and continuous. Additionally the vcovering of the pinion e andthe toothed portions of the guide-racks II not onlya excludes these from sight, but also precludes the catching of the clothing therein. i
