CONVERTIBLE SPRING SEAT AND BED.
Specification of Letters Patent.
Patented Dec. 4. 1906.
Application filed September 10, 1906. Serial No. 333,968.
To all whom it may concern:
Be 'it known that I, EDGAR WEBSTER SUM- MERS, of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Convertible Spring Seats and Beds, of which improvement the following is a specification, reference being had to the accompanying drawings,forming part of this specification, in which' Figure 1 is a vertical's'ection taken in line 1 1 in Fig. 2, the fabric and padding portion of the seat removed. Fig. 2 is a plan view of the seat, showing the spring-supports and underframing only. Fig. tion taken in line 3 3 in Fig. 2, showing the springs partially compressed, as when used for a seat in a sleeping-car. Fig. 4 is 'a vertical section taken in the same line as Fig. 3, but with the support for apart of the springs removed, as whenused for a bed in a sleepingcar. Fig. 5 is an. enlarged sectional view through one pair of springs, showing an outer spiral spring and an inner spiral spring with metallic cap andbase lates. Fig. 6 is a top view of Fig. 5 with t e cap-plate removed. Fig. 7 is the same as Fig. 5, except havim the outer spring partially compressed and showing how one spring may be compressed independently of the other.
My invention relates to seats used-in sleeping-cars, clining chairs, &c.', the improveinent being mainly in the arran ement of the springs an spring-supports, w have their bottom support removed and become inactive when used as a bed, all of the springs being supported underneath and available when arranged for use as a seat.
In a reclining position apersonsweight is distributed over a comparatively large-area. Springs having the or ease that class of springproper resiliency with a person 111 "this. position do not offer sufficient resistance to prevent collapsing when the. ersons body is in a sitting position and t e weight imposed on a comparatively small area.
My invention wa the person when eit ting position.
In the drawings spring 1, the inner spiral s mon metallic cap-plate 3, te fined base-plate 4, which supports the outer spring, the floating base-plate 5, which with the-inner spring is suspended from the common cap-plate 3 devised to give ease to er in a reclining or sit-- I show the outer spiral ring 2. then com- 3 is a vertical sec bed-lounges, re-
ereby certain SPIHLgS by means of the common rivet 6, andwasher 7, which joins the inner and outer springs to the cap-plate through the common center of the springs 1 and 2, as shown in Fig. 6. I
I show the base-plate 4 in Figs. 1: and 2, the wooden end piece 8 of the underframing, and rear piece 9,attached thereto with screws;
The front channel-beam 10 is shown in Figs. 2, 3,.and 4. This channel extending along the front of the seat-base is attached at its ends to the wooden end pieces "8 and along its upper edge to the front edge of baseplate 4 by means of rivets 11. Under the front edge of base-plate 4 and above the lower flange of channel 10 I show awooden nailing-strip. Base-plate 4 has perforations 12 at each position of a spring 1. and the metal at the outer edge of said perforation is beaded ,or rolled outwardly over the lowerthereby locking Between the rows coil ofthe said spring 1, each spring 1 in position.
of springs and e ending from front to rear of base-plate 4 are pressed ribs 13,,which serve to stiffen the thin metallic baselate and transmit the spring load to the out and rear rails of the seat-frame. The baseplate 5 has perforations 14, which perforations 14 are located at each position of an inner spring 2, and the metal at the outer edge of said perforations 14 is beaded or rolled outwardly over the lower coil of the said springs 2, thereby locking each spring 2 in its position.
It will be noted in Fig. 1 that base-plate 5 does not extend to the wooden end pieces 8 and in Figs. 3 and 4 that it does nbt extend to the front and rear beams 9 and10,'b ut is suspended from the springs 2 and has pressed ribs 15, which register with ribs 13 in baseplate 4. In Figs. 3 and 4 I show a portion of the ordinary sleeping-car framing as the wooden partition 16 with its upper and lower portions broken away. This partition is that portion of the car-framing which is between theberths of'the ordinary sleepingcar or between the backs of the seats when made up as a day-coach. F also show a portion of the frame 17, which serves as a suport fo the spring-seats when used as a seat in Fig. 3 -and-when' used as abed with the spring-seat drawn out in Fig. 4. I show cross-bars 18, which are fixed on supports 17 and serve to hold up base-plate 6 when use as a seat. hen the seat is drawn out, as in Fig. 4, the base-plate '5 has no under support and is carried by means of the attachment of IIO 7 when ln-useasabedz I the ordinary upholstering materials 19,
