Speciication of Letters Patent.
' Patented Mar. 20, 1917.
Application filed May 17, 1916. Serial No. 98,041.
To all whom t may concern.'
Bc it known that I, Orino D. REISINGER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Car-Seats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in car seats, and particularly to such seats having shftable backs for changing the direction in which the seat faces. To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.
In the accompanying drawings, which illustrate the invention, like characters iiidicate like parts throughout the several views.
Referring to the drawings,
Figure 1 is an end elevation of the improved car seat, some parts being diagrammatically indicated by means of broken lines, with some` parts broken away .and some of the exposed parts shown in section;
Fig. 2 is a front elevation of the invention, as illustrated in Fig. 1, with a portion of the car structure diagrammatically illustrated 'by means of broken lines,
Fig. 3 is a view, principally in transverse vertical section taken on the line m3 w3 of Fig. 2; and U t Fig. 4 is a fragmentary d etail view, with some parts sectioned on the line m4 of Fig. 1, on an enlarged scale.
The numerals 1, 2, 3 and 4 diagrammatically illustrate partly by Ibroken lines, the floor, side, window sill and heating pipes of a railway passenger coach.
The numeral 5 indicates a pair of laterally spaced leg castings screwed or otherwise rigidly secured in position to the car floor 1. Integrally formed with the upper extremity of each leg casting 5, is a horizontal flange 6. These horizontal flanges 6 5o are turned outward in opposite directions and have integrally formed with their outer edge portions vertical flanges 7. The upper extremities of the leg castings 5 are rigidly secured against lateral movement by a pair of angle bars 8, having their horizontal flanges turned toward each other and their vertical flanges turned downward. (See Fig. 3). The vertical flanges of the bars 8 rest directly upon the horizontal flanges 6 and their horizontal flanges rest upon 60 lugs 9, integrally formed with the vertical flanges 7 of the leg castings 5. The ends of the bars 8 abut against the inner faces of the flanges 7 and machine screws 10 detachably connect the bars 8 to the lugs 9. A seat 65 proper 11 closely fits between the flanges 7 and is detachably and removably supported on the bars 8.
A shiftable back 12 is supported by and between a pair of brackets 13 having, at 70 their lower extremities, a pair of axially alined trunnions 14 journaled in the vertical flanges 7 and bearings 15, integrally formed with the horizontal flanges 6. These trunnions 14, as shown, are preferably made independent from the brackets 13 and have angular interlocking engagement therewith at 16, to connect the vsaine for common oscillatory movement. The outer ends of the trunnions 14l are provided with heads 17 to 80 prevent axial displacement of the trunnions 14 from the brackets 13 by an inward movement. The back-supporting brackets .13 are supported in their two extreme positions on stop lugs 18 integrally formed 85 with the flanges 7. These stop lugs 18 have upturned flanges v 19 with inner Vbeveled. surfaces, with which the brackets 13 engage to crowd the same toward the flanges 7 and prevent lateral movement of the said 90 brackets 13.
The upper extremity of each bracket 13 is bifurcated tovform an open seat V2O t0 receive by a vertical movement headed gudgeons 21 on the upper extremities of flat 95 bars 22 screwed or otherwise rigidly secured to the end of the back 12. Y On the lower extremities of these bars 22, is a pair of axially alined studs 23, which work in segmental slots 24 formed in the brackets 13, the radii 10o of these slots 24 extending from the axis of the seat 20. Each bracket 13 has, above its slot 24, a pair of oppositely extended surfaces from each of which extends a pair of horizontal outturned lugs 25. A pair of arm rests 26 is secured by screws to each pair of lugs 25, on the outer bracket 13. These arm rests 26 are arranged to be brought alternately into operative positions, under the oscillatory movement of the ilo bracket 13 in the movement of the back 12 from one extreme position to the other, to change the direction in which the seat faces.
rilhe back 12 may be removed from the brackets 13 by turning the same into an intermediate position to carry the studs 23 into alinement with channels 2T, formed in the inner faces of the brackets 13 and arm rests 2G, and then lifting the same. (See Figs. 3 and Obviously, the gudgeons 21 support the back 12 from the bracket 13, with freedom for horizontal swinging movement, and the studs 23 limit the oscillatory movement thereof. The gudgeons 21 and studs 23 support the back 12 in an inclined position and the studs 23 are held in the lower extremities of the slots 24, under the action of gravity.
1n the shifting of the back 12 to change the direction in which the seat faces, a foot rest 2S is automatically shifted thereby from one extreme position to the other. This foot rest 2S is in the form of a horizontal bar secured to a pair of arms 29 Aby forming in said arms sockets to receive the ends of the foot rest. Integrally formed with the other end of each arm 29, is a sprocket wheel 30 and a disk-like guard 31 therefor. The sprocket wheels 30 and their guards 31 are journaled on a pair of axially alined trunnions 32. One of these trunnions 32 is secured to each leg` casting 5, has angular interlocking engagement therewith to hold it against rotary movement, and is held against axial movement by a shoulder 33 and a nut 34. rThe shoulders 33 are formed on the trunnions 32 and engage the inner faces of the leg castings 5 and the nuts 34 have screw-threaded engagement with the outer ends of said trunnions and bear against the outer faces of the leg castings 5. A nut has screw-threaded engagement with the inner end of each trunnion 32. y Oscillator-y movement is simultaneously imparted to the arms 29 by a pair of sprocket chains 36, the intermediate portions of which run over the sprocket wheels 30. The end of each sprocket chain 3G is anchored to a two-part arm 37. One of these arms 37 is pinned to the inner end of each trunnion 14. Horizontal stops 38, integrally formed with the inner faces of the leg castings 5, limit the oscillatory movement of the arms 29 and afford supports for the foot rest 28 in its two extreme positions.
Among the many advantages of the improved car seat are the simplicity of construction, few parts to get out of order and the ease with which the back and foot rest may be shifted. By setting the leg castings inward from the ends of the seat, a relatively wide aisle is obtained between the outer leg castings of opposite seats and a good clearance is obtained between the inner leg casting and adjacent side of the car body for the heating pipes. The construction of the seat and arrangement of the foot rest afford a large amount of room under the seat, where grips and other luggage may be stored. In cleaning a car, equipped with my improved seats, the backs thereof may be set in intermediate positions, in which positions the foot rests are at their highest points making it extremely easy to scrub or clean the car under the seats.
1n some instances, it might be desirable to use a train of three gears as a connection between the brackets 13 and arms 29 in place of the sprocket wheels and chains.
