CHARLES K. PIOKLES, OF ST. LOUIS, MISSOURI, ASSIGNOR TO SAMUEL M. DODD, OF SAME PLACE.
STEP-OVER CAR-S EAT.
SPECIFICATION forming part of Letters Patent No. 613,423, dated November 1, 1898.
Application filed December 13,1897. Serial No. 661,722. (No model.)
To a/ZZ whom t may concern:
Be it known that I, CHARLES K. PIoKLns, a citizen of the United States, residing at St.
Louis, in the State of Missouri, have invented certain new and useful Improvements in Step- Over Oar-Seats; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had tol the accompanying drawings, forming apart of this specification.
The present invention relates to car-seats, and more especially to that type of car-seats in which the seat-back has a step-over movement in its reversal action over the seat por# tion, While said seat portion has a movement in unison with the seat-back, but in an opposite direction, to afford in each position full seating capacity and a proper slope of the seat with relation to the back, an example of which may be found in'my former application for Letters Patent, Serial No. 655,815, filed October 20, 1897.
The objects of the present improvements are to provide a simple, durable, and effective connecting mechanism between the seat or chair parts, whereby the shifting movement that is imparted to the seat proper is amplified to an extentthat will expose for effective use the full width of the seat from front to back and with which the relative movements of the parts are attained in a certain and positive manner, as will hereinafter more fully appear. I attain such objects by the construction illustrated in the accompanying drawings, in which- Figure 1 is an end elevation of a step-over car-seat embodying the present invention,
one position of the step -over back being shown in full lines and the 'other position in dotted lines; Fig. 2', a detaillongitudinalsection at line cc @Figs 3 and 6; Figs. 3 and 4, detail sectional elevations at lines fc and m2 m2, Fig. 6; Fig. 5, a side view of one of the shaft-hangers of the intermediate gearinglin a detached condition; Fig. 6, a detail plan view of the mechanism atone end of the carseat, the back-arms being shown in section at line x3 w3, Fig. 3. l
Similar numerals of reference indicate like parts in the several views.
Referring to the drawings, 1 represents the seat portion, of any usual construction and provided at each end with end plates 2, each of said plates being formed with a horizontal toothed rack 3, preferably of a rectilinear form, and with a horizontal supporting slot or recess 4, preferably of a curved or segmental nature, as shown.
The chair base or support will be of any usual and approved construction and in the ypresent invention will be provided with end plates 5, each of which,- is provided with a toothed `rack 6, preferably of a curved or segmentalV nature, with a horizontal conning slot or recess 7, preferably of a curved nature and concentric with the toothed rack 6, and with supporting projections or studs 8, that have engagement in the supporting slot or recess of the seat-plate 2 to support and limit the seat in its shifting movement. Such shifting movement of the seat portion is a combined sliding and tilting movement in a directionopposite to that in which the seatback 9 has movement. The amount of such tilting movement of the seat will depend upon the amount of curvature given to the supporting slot or recess 4.- in the end plate 'of the seat portion, so that by modifying the form of said slot or recess a corresponding change Will be made in the movement of such seat portion.
9'is the step-over seat-back, preferably of the straight form shown, and finished or upholstered on both side'sor surfaces.
10 are the supportingarms of the seatback 9 and which, as in my -aforesaid prior application, may be of a substantially counterpart formation, with their upper ends having pivotal connection with the arms of across-head 11, attached to the respective ends of the seat-back 9, as shown, while their lower ends are provided with guide studs or projections 12 andwith sector-shaped ends 13, concen`V tric with the guide studs or projections 12 and preferably of a toothed nature, as shown, and adapted to engage and move upon the corre-l spondingly-formed track on toothed rack 6 on the end plate of the chair standard or base in a manner similar tothe construction as shown and claimed in my aforesaid prior-aptoo plication, the engagement of the parts being such that the lower ends of the back-supporting arms will move in the same direction as the upper ends thereof, so that the arms may be of a shorter nature than the arms heretofore employed in the present class of stepover ear-seats.
In the present improvement the slidingr movement of the seat portion 1 in a direction opposite to that of the seat-back, as heretofore described, is attained in an indirect manner by the following mechanism:
14 is a shaft-hanger formed with eyes ororiflces 15 at each end, that have engagement with the studs or projections 12 on the supporting-arms 10 of the seat-back and with an intermediate orifice 16, that forms a bearing for the shaft 1'7, extending from end to end of the seat and supported at the end by a counterpart arrangement. 18 are pinions at the respective ends of said shaft, that have engagement with the respective toothed sector-shaped ends 13 of the back-supporting arms 10 to receive motion therefrom and at the same time connect the same together, so as to move in unison in a positive manner. 19 are gear-wheels of a larger diameter than the pinions 18, also secured to the respective ends of the shaft 17 and adapted to engage with the toothed racks 3 upon the seat portion l. With this construction the shaft 17, with its gear-wheels and pinions 19 and 18, moves from side to side with the sector-shaped ends of the supporting-arms 10 in a reversal of the car-seat, and the dierence in the relative diameters of the pinions 18 and gearwheel 19 governs the amount of shifting movement imparted to the seat portion 1, so that by a relative change in such diameters a corresponding change can be attained in the amount of the shifting movement of said seat portion 1.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-
