`To all whom 'it may concern:

Be it -known that I, WILLIAM W. Hor- Kms, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Davenports, of 'which vthe following is `a full, clear, and exact description, such as will enable 'others skilled inthe art to lwhich it ap- .pertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Y Y Figure 1 is an elevational view of m improved davenport, the near side wall eing removed to more clearly show the construction of the moving parts. Fig. Q is a similar view showing the parts in changed positions. Fig. 3 is a similar view showing the prarts in still another position. Fig. ltis a ont elevational view showing the parts in the position illustrated in Fig. 1, the middle i portion of the davenport being broken away.

This invention relates to a newxand useful improvement in foldingl davenports of that character wherein the seat portion can beA folded over and the back portion folded down, so that a bed maybe formed, said porositively connected together, and' constituting what is known as a one movement reversible davenport.V The under side of the seat portion and the rear side of the back portion are provided vwith mattresses, such for instance, as woven wire mattresses, so that whenthe parts are moved in to' position to forma bed, the mattresses w1ll e uppermost.V rIhe opposite faces of the seat and'back port-ions are upholstered in the usual way, so that lwhen, the partsl are- -in theposition shownin Fig. 1, andthe device used as a davenport, 'the upholstered portions will be in use. A In the drawing there are two end walls V 1, connectedy by a bottom wall 2, and front and back rails 3, said bottom wall and rails.

forming a trough or box in which bedclothes, pillows and the like may be kept. The end walls maybe connected by a back wall or tie-rod if desired, but this is not essential. 4 and 5 are bearing plates secured to the end framel into which are trunnioned the seat and back frames 6 and 7 respectively, the trunnions being held in position by hooks 4a and 5a as shown, said hooks preventing the trunnions being lifted out of the bearing plates when the parts are in the position toform a davenport as shown in Fig. 1. The free edge of the seat portion is supported by a projection 7a extending 'fromthe back frame. To this projection is' secured a spring 8 for counterbalancing the ak when the same is swung down upon a 9 isan l.shaped link pivot-ally connected to the end plates of the seat and back frames, there being a link at each end of the davenort. p Indescribing the operation of this link, l will assume that the dotted line a-b indicates the axial line of the seat portion, while the line c-d indicates the axial line of the back portion. The pivial point of connection of the link 9 to the s at portion, is below the axial line a-b as shown in Fig. 1, so that when the strap 10 connected with the free edge of the seat portion is grasped to lift the seat as shown by dotted line in Fig. 1,

said pivotal point moves in the are of a cirl cle indicated by the line e, and as the pivotal point of connection of the link 9 to the back portion moves in the arc of.a circle indicated by the line f, the back portion is caused to be tilted to the rea-r as shown by the dotted lilies. This is a desirable feature of my invention and follows from the fixed relation of the pivotal points of link 9.to each other. By tilting the back portion rearwardly, the upholstering thereon is not rubbed by the upward movement of the free edge of the seat portion. In the opposite movementbf tlie'parts,.when the seat is being restored home, the back portion is tilted rearwardly to admit of the downward movenient of the seat, and when the seat is home,

the link 9 draws it forwardly so as to cause the upholstering to Afit over the seat snugly. The 'link 9 holds the back firmly in its vertical position. ln addition to the act-ion of the `link 9, the free edge of the seat engages the stops 7a and tends to tilt the back portion forwardly.

W'hen the seat portion is lifted to the positio'n in Fig. 2, access is had to the box thereunder, which,'las before described, may be used for the storage of bed-clothes, pillows, etc., when not inuse. Further movement of the seat portion causes the parts to assume the position shown in Fig. 3 in which position, a pivoted leg 11 swings downwardly to support theI free edge of the sea-t. When theA seat portion reaches a vhorizontal position, that is, when the leg 11 1s on the ioor, the pivotal point of link 9 to the seat portion becomes av fixed point or ulcrum. The trunnion or pivotal point of support of the back portion is also fixed.

The pivotal pointof connection of link 9 -to the 'back portion'is movable, and in order Ito prevent the back portion from slamtion occupied by the back portion'when thev seat portion is extended outwardly, and rests upon its leg 11. In this osition the dotted line g--t indicates thev ine of centers between the two fixed fulcrums to-wit; the pivotal point of connection between the link 9 and the seat portion, and pivotal point of the back portion.

Swinging from the irst mentioned lixed fulcrum, the movable pivotal points of connection between link 9 and the back ortion,

y tends to move in the arc of a circ e indicated by the line d, while the same movable pivotal point swing-ing in the arc of a circle 7, described from the second mentioned` pivotal point to-wit; the pivotaly point of the back portion. The rigidity of the end frame of the back portion will cause. the pivotal point to move in the arc of a clrcle described by the line j, while the link 9 will be strained in its effort to follow the line z', the link 9 thus acting as a spring and being under compressionuntil the line g--al is passed, when the sprin in link 9 restores the link r'to normal, an tends to hold the back portion down. 'This snap of the toggle is preferably)7 caused by a yielding link 9A but it is o vious that lost motion could be provided at the pivotal points in which event link 9 could berigid. When the parts are worn, lost motion thereof, will detract from the spring action of link 9.

In the position of the 1t is impossible to raisethe seat portion by lifting itl at the free edge thereof, because to do so would place the link 9 in com ression-the arcs of movement described, rom

the pivotal point of the seat and the pivotal point of connection between link 9 and the back portion, being diierent. It is therefore necessary to llft the front edge of the lback ortion by means of a strap 13 breakin t e to ejoint which has acted as a lox to hoIfIthe seat and back frames .in horizontalNalin'ement. A

IWhen theback portion lies in its horizontal position, the spring 8 is under tension, and acts as a counterbalance. The free edge ofthe back portion issupported in its horizontal position by the pin 14, which rests parts shown in Fig. 3

on the top of a post 15, as shown in Fig. 3. This post 15 also coperates with thc end of link 9 when the seat portion assumes its horizontal position. v

l16 indicates a lever pivotally mounted on the end framing of the davenport, there being preferably a lever at each end of the davenport, the lower end of said lever projecting outwardly slightly beyond the end of the davenport, and the upper end terminating under a pin 16a on the end frame of the back portion when in its horizontal position. A spring. 16b holds the lower end of the lever up. This lever enables the operator to break the toggle and lift the back portion upwardly to the position shown by dotted lines in Fig. 3, without necessitating the use ofthe straps 13. When-the back portion is raised to the position shown in dotted' lines,l where it is sustained by the links 9, the operator can then lift the back .portion to its vert-ical position by reversing the seat portion. Thus it is unnecessary by the use of the lever 16 to attach the back -portion in changing from a bed to a davenport.

I claim:

'1. In a davenport, a supporting frame, seat and back portions' pivotally mounted therein, and' a link connected tothe back portion in front of its center line, and to said seat portion below its center line, when the parts are in position to form a davenport,-whcreby said seat and back portions are alternately placed in control of each other in changing from a davenport to a bed and vice versa.

2. In a davenport, a 4supporting frame, scat and back portions pivotally supported thereby, and a inkconnecting said portions in such manner that when the seat portion is lifted to be swung upwardly and outwardly, the back portion is caused to be tilted rearwardly, wardly by said link.

. 3. In a davenport, a supporting frame, seat and back ortions pivotally mounted `therein, means or of said seat portion when in its outer position, means for supporting the free edge position, and a link pivotally connected 'to said seat and back' portions at relatively fixed pivotal points, the oint of attachment of said link to said-back ortion being below the line of centers of t e pivotal points ofv said seat and back ortions when said parts are in horizontal aIineinent.

4. In a davenport, the combination of the supporting -frame, back and seat portions plvotall arranged therein, a link connecting sal portions, whereby when the parts are in a position to form a daven ort, the rear ed of the v'seat may be li swung orwardly and outwardly, the .piv-

and then swungA forsupporting the free edge d and v 1lb of saidv back portion when 1n its horizontal i tilt backwa'rdly before swinging forwardly to a horizont-al position, and counterbalaneng devicesfor said parts.

5. In a one movement reversible davenport, a supporting frame, seat and back portions pivotally mounted therein, and a link connecting said portions whereby in moving the parts to form a bed, the seat constitutes the operating medium for the back portion, tilting the same rearwardly before moving it forwardly, and when moving said parts to form a davenport, the back portion consti-I tutes the operating medium for the seat.

6. In a davenport, pivotally mounted seat and back portions, a link connecting said portions and serving to lock them -in horizontal alinement, anda foot lever coperating with the back portion to raise itto a position where it can be operated by the seat portion through the mediumof said link.

In testimony whereof I hereunto aiX my signature in the resence of two witnesses, this 16th day of ctober, 1909.
