SEAT-SPRING FOR CUSl-llONED SEATS.
SPECIFICATION forming part of Letters Patent No. 447,142, dated February 24, 1891. Application fi ed September 13, 1890. Serial No- 364.896. (No model.
To aZZ whom it may concern..-
Be it known that I, \VIlILIAM WEs'rnRMA NN, acitizen of the United States, residing at Louisville, county of Jefferson, Sta of Kentucky, have invented tt. L-dlttll1 new and usei'ul Improvement in SeatS1in-ings l'or (lush- IonedSeats; and I 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 pertains to make and use the same, reference being bad to the accon'e partying drawings, which form a part of this specification.
This invention has for its object to provide a novel, simple, and el'licient spring-seat; and It consists in the combination, with a seatframe, of a series of springs overlapping and bearing upon each other for mutual support and each composed of a curved strip having botlrof its end portions formed with coils and bearing-arms, said coils located within the seat-frame flush with or below its top surface, and the bearing-arms resting on the latter and rigidly engagedwith the frame.
The invention also consists of other fea tures of construction and combination or an raugement of parts hereinafter desc' bcd and claimed, reference being made to the accompanying drawings, in which Figure l is a plan view of the frame of a chair illustrating my invention. Fig. 2 is a s de elevation of the same. Fig. 3 is a plan view illustrating a variation. Fig. 4. is a side elevation of the same.
In carrying out my invention, A represents a seat-bottom. This may, of course, be any seat-botto1nas, for instance, for a chair, sofa, carseat, 01' the like.
13, B, B &c., represent the springs. They are each coiled at each end, as shown at b, and the extreme ends 11 are carried outward and passed down into and preferably through the seat-frame, and there secured, and il passed through. the scat-frame, as shown, the extremity may be turned and clinched, as shown at The portions 11 form. horizontal. bearn'ig-arms, which rest upon the flat surface of the seat-frame, so that any downward pressure upon the spring is communicated directly to these portions 11', and hrough them transmitted direct LlUWllWZLlCl upon the seat-frame, the said frame itself serving as a resistance or fulcrum to prevent any downward movement of the coils 7) when the seat is in use. arranged, as shown, so that they shall. lie wholly beneath or llush with the upper surface of the seatt'rame. in the position shown they are out of the way of. the upholstery, and are where they are not liable to be inj urcd or distorted by any accidental means. It is manifest that these springs may be arranged in a yariety of ways so .long as they overlap each other for mutual support. As shown in Fig. .1, they may cross the seat from front to rear, the springsll and 13" turning toward. the center and overlapping the springs 13 and 13 which are arranged along the middle and turn'toward the ends. So, also, as shown in Fig. 3, sprii'igs arranged on opposite sides of the seat and projecting inwardly may overlap the springs which projeet inwardly from the two remaining sides.
It will be observed that in this contrivance but very lit-tie spring metal is employed, and that the device is wholly devoid of any other elements than. the plain scat-fran'ic and the said springs and does not require the pres.- ence of a rung or red a fulcrum for the springs. The complete structure is therefore exceedingly cheap and simple.
'What I claim is l. The combination, with a seat-frame, of a series of curved springs overlapping and bearing upon cachother for mutual support and having each end portion. formed with coils h and a bearing-arm I), said coils located llush with or below the top surface of the seat-frame, and the bearing-arms resting on the latter, extending through the frame, and clinched to the under, side of: the latter, substantially as described.
2. The combination, with a scat-frame, of a series of springs overlapping and bearing upon each other for mutual si'vpport, and each composed of a curved strip of wire having both of. its end portions formed with coils h and bearing-arms 71, said coils located within, the seatsframc ilush with or below its top surface, and said bearing-arms resting on. the latter and. rigidly engaged with. the frame, substantially as described.
In testimony whereof I sign this specification in the presence of two witnesses.
