BED DAVENPORT.

Application filed July 7 25,

This invention relates to davenports and especially to that class thereof which are adapted to be extended to form a bed.

The objects of the invention are, first, to provide such a bed davenport which is as strong in its framing as the usual davenport; second, to provide such a davenport which is, in no way, distinguishable in appearance from the usual davenport; third, to provide means whereby the spring parts of the davenport bed lie in the same plane with and are alternated with the corresponding parts of the fixed portion of the davenport; fourth, to pro vide means for bridging the space between the spring portions of the bed extension; lifth, to provide means for bridging the space between the spring parts of the fixed portion of the daven port, when the bed part thereof is extended; sixth, to provide improved guiding means bet-ween the fixed part and the extension whereby the motion of the extension is controlled and whereby it is prevented from binding, even if it is pulled or pushed from one of its corners; and seventh, to provide means adapted to hold the bed portion in extended position until it is desired to return it to its normal or closed position. A further object is to provide a n'ieans for mounting the springs of the davenport and its extension, whereby they form integral groups or cushions. Another object is to provide automatic legs for the bed extension whereby, when the bed is in extended position, the legs automatically assume a supporting position and whereby, when the bed is being returned to its closed position, the said legs are withdrawn and stowed away automatically. A further object is to provide a bed davenport which 'is simple and economical to manufacture, easy to operate, and which provides ample spring supporteit-her as a spring mattress for the bed or as a spring seat for the davenport.

I attain these and other objects by the devices, mechanisms, and arrangements illustrated in the accompanying drawings, in which- Fig. 1 is a front elevation of the bed davenport, in its closed position; Fig. 2 is a side elevation of a portion of the end of the extension frame and the supporting fixed frame, in extended position, to illustrate the automatic latch between the parts; Fig. 3 is a cross-section of the rear canvas apron roll, showing it in partly extended position and in relation to two adjacent spring e' ilshions Fig.

1927. Serial No. 208,200.

Similar numerals of reference refer to similar parts throughout the several views.

The fixed portion of my improved bed davenport is made with a frame which is very similar to the usual construction of a davenport ineapableoi' extension andisin every way as strong thereas. This frame comprises a front lower rail 1, supported on three front legs 2; a parallel rear lower rail 3, supported on two legs 4, which extend upward to form the ends 5 of the back framing, indicated by the parts 6 extending between the said end posts 5 together with two side or end frames, formed of the lower horizontal rails 7, joining the above described front rail 1 with the rear rail 3, the front arm posts 8 and the arm frame rails 9, joining the

posts

5 and 8. Besides the above, there is a central rail 10, positioned at a lower level than the rails l and 3, to which it is secured, and forming a guide for the bed extension, as hereinafter described. The fixed frame is also provided with means for supporting the fixed portion of the spring seat and bed. The lower rear rail 3 of the fixed frame is best illustrated in Figs. 4, 10 and 11, that form shown in Figs. 5 and 6 being a variation thereof. The lower rail 3 is preferably provided with a rabbet 11 extending from end to end thereof and positioned on a level with the upper side of the front rail. 1. A series of parallel spring cushion-supporting slats 12 are secured in said rahbet 11. and extend. therefrom to the front rail 1. on which they restand to which they are suitably secured. These slats 12 are spaced apart a sufficient distance to permit a similar series of slats on the bed extension to lie between them as hereinafter describet.

The bed or extension frame comprises a rear rail 13, positioned on the same level the above-described front rail 1 of the fixed frame, and lying above the above-described central rail 10; with two end rails 14 and a front rail 15. The level of the front rail 15 is above the upper surface of the front lixed rail 1, as clearly seen in Figs. 8 and 10. The extension frame is also provided with a central rail 16, extending from the rear rail 13 to the front rail 15, and lying inunediately above the level of the fixed front rail 1 (Fig. 4:). This extension frame is also provided with a series of parallel spring cushion-supporting slats 17, secured to the front and

rear rails

15 and 13 thereof, and lying between the slats 12 of the fixed frame, as above described.

The extension frame is supported, at its rear, by the fixed frame, especially at the ends and center by the

rails

7 and, 10, and at its front, by means of two retractable legs, illustrated in Figs. 7 and 8. These logs comprise suitably shaped bodies 18, pivoted at 19 to the end rails 14 ofthe bed extension, near the "rent thereof, and each having their upper surfaces curved substantially as shown in the drawings, and a helical spring 20. one end of which is secured to the uppcrpart of the leg, above the pivot 19 and the other end of which is secured to the said rail 141-, said Sl ')l'l11g being always under tension. Thus, when there is nothing to hold the lower end of the leg 18 up, the spring 20 turns it on its pivot 19 and brings its lower end down into contact with the floor. A stop 21 is provided in such posi tion as to limit the motion of said leg to such vertical position. When, however, the extension frame is moved rearward to close it, the leg 18 first slides along the floor and then engages the front rail 1 of the fixed. frame, at a point below the pivot 19, and is thus turned thereby on its pivot into its retracted position, as shown in Fig. 8, against the action of the spring 20. The leg 18 remains in this position, resting on top of the front rail 1, until the extension frame is drawn out again, when it again turns vertical as soon as it is removed from contactwith the said front rail 1 of the fixed frame.

I prefer to place metal gliders 22 between the several moving parts in order to cause a free and smooth motion therebetween, with but little friction. In Fig. 2 I have shown a glider 22 mounted on the upper side of the fixed supporting end rail 7, at the front end thereof, and a similar glider 22, in reversed position, on the lower side of the rear end of the end rail 14: of the extension frame. Also, in said view, it will be seen that I have provided notches 23 in the said

several parts

7 and 14, adapted to receive the gliders 22 of the other part when the extension frame is at its extended position, said notches 23 bein quite shallow in depth and with an easy incline. These notches, cooperating with the said gliders 22, tend to hold or latch the extension frame in its extended position. However, when it is desired to close the frame from its extended position, it is only necessary to raise slightly thereon or, indeed, to push inward thereon with sufficient force to cause the said gliders to slide up out of the said notches 23, and the extension frame will then slide easily and smoothly back into its closed position.

Referring now particularly to Fig. 1 of the drawings, wherein the means for guiding the movement of the extension frame on the fixed frame is illustrated, it will be seen that the central guide rail 16 of the extension frame liesimmediately over the coresponding guide rail 10 of the fixed frame. The front rail 1, of the fixed frame, is provided with two guiding flanges 24L which extend upward therefrom and which engage the two sides of the said extension guide rail 16. Also the roar rail 13 and the rear end of the said guide rail 16, of the extension frame, are provided with guiding lugs or flanges 25, which extend downward therefrom and which engage the two sides of the said fixed guide rail 10. Thus it will be seen that the extension frame is guided at its center by the interaction of the guiding lugs 2% and 25 on the respective guiding

rails

16 and 10, and that they prevent any jamming of the extension frame in relation to the fixed frame as they engage the respective parts at well separated positions.

Referring now to F ig. 9 of the drawings, in which I have particularly illustrated the construction of one of the spring cushions which form an important part of my invention. This springcushion consists of a rectangular casing of fabric in which the series of springs for the seat or bed are mounted, and which forms a long spring body, flexible in all directions, which groups the set of springs therein into an alined spring cushion, which is self-contained and which is of reasonable stiffness longitudinally thereof. Each cushion, then, comprises one of the above described slats 12 on which are fastened a row or series of helical springs 26, and to which the fabric container 27 is secured. This cushion. then, consists of a fabric box, extending substantially the length of the slat on which itis formed, and enclosing a group of springs 26, said springs being under an initial compression, and being secured to the said fabric box at convenient points therein. In practice I prefer to form the springs 26 with rectangular upper and lower coils or loops, as shown in Fig. 9, so that two adjacent springs will have their upper and lower coils close together and they may be fastened to the supporting LOO 12, or to the fabric 27 at the same place, and so that the said rectangular upper coils will shape the fabric box 27 with substantially straight upper edges. Thus it will be seen that each slat 12 is provided with a spring cushion of rectangular form, whose sides are in tension under the action of the springs contained therein.

It will be seen by the drawings, as Figs. 5 and G, that there are two sets of these spring cushions, the cushions 28 being mounted on the slats 12 of the fixed frame, and the simi lar cushions 29 which are mounted on the slats 17 of the extension frame and that, when the dm'enport is closed (Figs. 1, 6 and 10), these two series of

cushions

28 and 29 alternate in position to form the spring seat thereof and, when it is extended, each set of

spring cushions

28 and 29 form a portion of the bed thus formed.

The fabric spring cushions29, which are mounted on the slats 17 of the bed extension frame, are elevated very slightly above the spring cushions 28 on the slats 12, of the fixed frame, as clearly shown in Figs. 3, 5, 6, 10 and 11. All the said spring cushions 29 of the extension frame are secured together by means of two, or more, flexible connections such as wires 30, which are secured thereto and which stretch across and bridge the tops of all the said series of spring cushions 29, and which are secured to the end rails 14 of the extension frame through the interposition of coiled springs 31. Thus, althougheach said spring cushion 29 is fairly rigid or sti'tt' longitudinally, on account of the fact that the springs are alined in that direction, they are stiffened transversely of the said slats by being connected together by the said wires 30. Since the said spring cushions 29 are higher than those on the fixed frame, it is evident that the said bracing wires 30 pass over the tops of the said other spring cushions 28 on the fixed frame. However, the said lower spring cushions 28, 011 the fixed frame, are also attached together along their rear upper edges by means of the wire 32 (Figs. 3, 5, 10 and 11) which is stretched between the ends of the fixed frame, and which has a spring connection thereto, not shown.

lVhen the davenport is closed, therefore, the spring cushions 29, of the extension frame, are alternated with the spring cushions 28, of the fixed frame. The two sets of spring cushions are not in any way attached together but each set is secured together into a single resilient structure, as above described. The one resilient structure is interpositioned in the other resilient structm'e. Thus the whole seat formed by the alternating spring cushions 28 and 29 forms a stiff spring body of great resiliency.

A roller 33 is mounted in the rear framing of the fixed portion of the clavenport, at a point below the spring cushions forming the back thereof, said roller having an internal torsion spring 34 (Fig. 3) mounted therein and tending to resist its rotation in an unwinding direction, as hereinafter outlined. An apron 35 is rolled on the said roller 33 and is attached thereto at its inner end and to the rear upper edges of all the spring cushions 29, of the extension frame, at its outer end. This apron is made of heavy fabric, such as canvas. lVires 36 are secured to said canvas apron 35, on'e such wire being positioned at the outer edge thereof and to the several spring cushions 29, the other wires 36 being parallel therewith and spaced at short intervals apart, all said wires being parallel to the axis of said roller 33 and at right-angles to the axes of the several spring cushions forming the davenport. lVhen the extension frame is drawn outward, the spring cushions 29 pull the canvas apron 35 and unwind it from the roller 33, against the action of the spring 34-. therein, and said canvas apron slides over the fixed spring cushions 28, as the extension moves outward, said apron and its wires 36 bridging across said fixed cushions and therefore reenforcing them laterally and distributing the weight applied thereto among the several cushions 28. The spring 34: always tends to draw said extension frame inward and it is held outward by the above described latch formed by the gliders 22 and the notches 23. WVhen the extension frame is returned into its closed position, by being pushed inward manually and by the action of said spring 34, the said apron 35'is removed from over the cushions 28 and is rolled on the roller 33, under the action of said spring 3-4. Having, therefore, described my invention,
