To all whom it may concern:

Be it known that we, ROBERT V. SU'rHnR- LAND and STANLEY G. SMITH,.citizens of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Davenports; and we 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.

This invention relates to a davenport and has for its objectand purpose the provision in a device of this kind of many new and useful features ofconstruotion and operation through which the davenport may when folded be used as a couch or settee or, when unfolded, as a bed or the like, the invention consisting in novel constructions for the operation of the folding and unfolding of the davenport sections, the raising and lowerlng of the under section as the device is made to serve the purpose of a bed or settee, and in a novel mechanism which looks and holds the parts frictionally in place to whatever position moved, the frictional locking means being included in the mechanism for the operation of the davenport. Many other features of novelty not specifically enumerated will be disclosed in the following description of our invention, reference being hadto the accompanying drawingsin which, Figure 1 is a partial sectional and plan view of the davenport in unfolded position when it is used as a bed.

Fig. 2 is an end view, certain of'parts being broken away and shown in section to better disclose the invention.

Fig. 3 is a front elevation of the davenport in its unfolded condition parts at one end being brokenaway and shown in section.

Fig. 4 is an end view of the construction shown in Fig. 3 with parts again broken away and inlseotion to disclose the structure.

'Fig. 5 is a fragmentary elevation similar to Fig.4: illustrating a slight modification in structure. a

Fig. 6 is a side view of a stirrup comprising a detail of construction and,

Fig.7 is a partial sectional and side view of another stirrup which is also used.

Like reference characters refer to like parts throughout the several views of the drawings.

The davenport includes a back 1 and ends 2 supported by the usual legs and casters. The back 1 at its upper front portion is provided with the usual cushion 8. Each of the sides 2 adjacent its front end carries a vertical rack a with which a gear 5 meshes, this gear being of a combined spur and worm type. The gears are mounted loosely at the ends of a rod 6 which extends the full length of the davenport and is bent clownwardly at its central portion as shown. A lower frame 7 is located between the ends 2 from the under side of which adjacent its rear side at each end a diagonal brace 8 extends downwardly and forwardly, said braces connecting at their front ends to the lower ends of posts 9 slidahly mounted adjacent the front end of each side 2 and at their upper ends hung on the ends of the rod 6. In the normal positionof the frame 7 its rear side may rest upon shoulders 10 formed in the back 1. This frame at its upper side carries a mattress section 11 which is supported bycoil springs 12. Plates 13 are secured at the upper front corners on the ends of the frame 7 and may be connected to the rod 6 adjacent its ends for the support ofthe front end of the frame. A second frame li carrying a mattress on its under side with a plurality of coil springs 16 interposed between the mattress and the outer and upper cover is connected at its lower front corners to plates 17 cast integral withthe gears 5. Two stirrups 18 are loosely mounted and depend from the ends of the rod 6 each being formed with spaced apart journals 19 between which a worm 20 is located, each worm being fixed on the end of a shaft 21 which has bearing in the j ournals 19. These shafts, one at each end of the davenport, extend upwardly and rear- Wardly to a point above a shaft 22 suitably mounted, in the modification shown in Figs. 1 and 2, and 4, between brackets 23 fixed at each end of the davenport, the shaft extending the full length of and through the back section 1. Spiral gears are secured at the ends of shaft 22 and a stirrup 25 is likewise loosely mounted at each end of the shaft 22 having spaced apart journals 26 through which the upper and rear end of shaft 21 passes. A spiral gear 27 is splined on the shaft between the journals 26 and meshes with gear 23. The rear end of each shaft 21 is squared, adapting it to receive a crank 28 for the operation thereof and to eliminate friction as much as possible one of the journals 26 has rollers 29 therein as shown in 27 against which shaft 21 bears.

In 7 the slightly modified construction shown in Fig. 5 the shaft 22 is movable with respect to the back 1 or what may be termed floating and the stirrups 25 are fixed thereon, the spiral gears 27 between the journals 26 of the stirrups also being fixed to the shaft. The rear end of the shaft 21 rests upon rollers 30 as shown.

With the parts as shown in Figs. 3 and 4:, to unfold the davenport, the shaft 21 at either end of the davenport is turned by the crank 28 or in any other suitable manner whereupon gears 5 are rotated and simultaneously climb the racks 4. As the upper frame 14 is permanently connected to the gears it swings about the rod 6 as an aXis through an angle of substantially 180 degrees and to the position shown in Fig. 2. The lower frame 7 at the same time is elevated by reason of the elevation of rod 6, and the connection of the frame as described to said rod, and in whatever position the shaft 21 is left the friction between the worms 20 and the gears 5 serve to lock the parts against free return movement. The

davenport unfolded presents the mattresses 11 and 15 in the same horizontal plane and on the upper side of frames 7 and 1st. On account of the elevation of the front ends of shaft 21 it will be clear that the rear ends of these shafts are moved rearwardly and in the modification shown in Fig. 5 the entire construction consisting of shaft 22 stirrups 25 and the various spiral gears moves rearwardly with the shafts 21 while in the modifications shown in Figs. 2 and 4 shafts 21 move to the rear through the journals 26 and the spiral gears 27.

To support the frame 14: when it is turned into the position shown in Figs. -1 and 2, a leg 30 is provided at each end ofthe frame and pivotally connected thereto. A coil spring 31 is interposed between each standard and the frame the tendency of which is to fold the leg upwardly in the position against the end of said frame. A link 32 is connected to each leg 30 a short distance from its pivot and lies along side the end of the frame at its rear end connecting to a short link 33, which as it passes over a stop 3 1 formed in the end 2 of the davenportby cutting away portion of the end above the top is forced to occupy the position shown in Fig. 2 automatically throwing the leg at each end to its upright position. When the upper frame or section of the davenport is returned to its original position after the link 33 passes the stop it may and easy in its action. By this construction it is possible to use regular coiled springs for the support of the mattresses and as the cushioning means for the seat of the davenport. Our invention as described is a practical embodiment thereof but we wish it understood that it is not the only embodiment of the invention and we consider ourselves entitled to all modifications which fall within the spirit of the appended claims defining the invention.
