Specification of Letters Patent.

Patented July 2, 1912.

Application filed August 5, 1909. Serial No. 511,319.

To all whom it may concern:

Be it known that I, LOUIS E. WEINMANN, a subject of the Emperor of Germany, and a resident of the city of New York, borough ofManhattan, in the county and State of New York, have invented a new and Improved Convertible Bed and Davenport, of which the following is a full, clear, and exact description.

The invention relates to the known article of furniture that normally has the eneral form of a davenport, but which may e converted into a bed.

It is my object to provide a new article of this general character greatly improved in various particulars as regards both the mechanical features and the esthetic appearance of the structure. Important desiderata in articles of the character referred to are the possibility of converting the structure from davenport to bed form, and vice versa, with a minimum expenditure of physical energy; effecting the conversion conveniently without bodily moving the whole structure from its normal position near the wall of the room, and the prevention of any damaging contact with the wall; these I obtain very effectively with my improved structure.

A distinguishing feature of my invention is that my improved article of furniture when adjusted as a davenport, presents the conventional appearance of an ordinary davenport; the bed features are well disguised; the operative devices and mechanism employed are normally concealed, and the convertible character of the structure is not apparent.

In the referred form of my invention the three mam elements of the seat, back and mattress, with their individual appurtenances, are mounted to be moved bodily inward and outward on a relatively fixed base, and are then shifted relatively to one another to so dispose the parts as to constitute a bed. In converting the structure into a bed, after the whole superstructure is moved outward on the base, the back is lowered and then occupies the position on the base that the seat occupies when the parts are arranged as a davenport, the movement of the back from an approximately vertical to a horizontal position serving to move also a mattress section.

The individual elements of the seat, back and mattress of my improved article embody distinctive features, alone and in their novel correlation, which will best be pointed out in detail in explaining the structural embodiment elected by me for the illustrated example of the invention. It is desirable to here mention, however, that my improved seat comprises a mattress that folds together in two folds onto the seat frame, the upper layer or fold when the structure is adjusted as a davenport, forming the seat cushion; this upper fold of the mattress presents on said upper surface an upholstered cushion; its opposite side constitutes one section of a mattress surface; the line of folding of the mattress is at the inside; that is, at the angle formed by the seat and back, the opening between the mattress folds or layers being at the outer edge of the seat. Moreover, the combined seat cushion and mattress fold includes an interior frame which serves to give permanent form and firmness to the seat cushion as effectively as does the fixed seat frame of the ordinary davenport. In form this cushion frame is such that the element of comfort afforded by theseat is fully maintained, and the parts of the cushion frame are so disposed that no unyielding surface or rigid member is presented at the front angle of the seat surface to cause discomfort. The cushion frame, furthermore, constitutes a carrier for the top fold forming the seat cushion and mattress section, and I may advantageously, as in the preferred form, establish a mutually cooperative lever-connection between the movable davenport back and the cushion frame; thus the lifting of the mattress frame enables the back to gravitationally assume the horizontal ositlon, and this downward movement of the back gives continued movement to the mattress.

The preferred mode of mounting the superstructure movably on the base is through the medium of a sliding carrier means to which the back, the seat, and the mattress are secured, together with their operative appurtenances. The seat and the mattress are mounted to be raised, if desired, to afford access to the box-like base without disturbing the back.

A further special feature of my invention is an auxiliary supporting devicefor preerence indicate corresponding parts in all the views.

Figure 1 is a general perspective view of the frames of which my davenport and bed are composed, with'the mattresses and cushions removed to expose the operative mechanism: Fig. 2 is a side view partially broken away, showing the parts in a davenport position; Fig. 3 1s a side view showing the davenport converted into a bed; Fig. 1 is a cross section showing the frames with cushions and mattresses removed for clearness of illustration, with the suitable seat frame and parts carried thereby withdrawn, in the first step of converting the davenport into a bed;

Fig. 5 is a cross section of the frames with cushions and mattresses removed, showing .the davenport converted into a bed; Fig. 6 is a top plan view which shows a detail of construction, the view representing a roller carried upon the stationary under frame and serving to reduce'the friction of a certain sliding member to be hereinafter more fully described; Fig. 7 is a side view of the same roller; Fig. 8 is a side view of the end of a channel iron carried upon the sliding member, the view showin two friction rollers; Fig. 9 is a section on t e line mm of Fig. 4; Fig. 10 is a section on the line y-y of Fig. 4; Fig. 11 is a cross section of a slight modification showing an automatically-swinging support for holding the seat when access is desired to the under frame, certain friction rollers for the seat section being omitted from this View; Fig. 12 is a similar view 5 of the form illustrated in Fig. 11, showing the parts in another position; and Fig. 13 is a detail of a rocking arm which serves to support the davenport back in certain positions.

My improved convertible davenport and bed comprises in general, in the form illustrated, a stationary base frame or box-frame A, having mounted thereon for bodily movement in unison a seat-frame B, a swinging mattress frame C, and a swinging davenport back D. In converting the davenport into a bed the mattress-frame C, and with it the back and the seat-frame are slid outward on the base frame A by pulling frontward the mattress frame C, then the mattress-frame C bottom member 12 and front board 12 'is lifted and'the davenport back lowers into a horizontal position and the mattress-frame is carried over onto the new hdrizontal back D.

It will be observed that in its outer and lowered posit-ion, the back D occupies the position on the base A that is occupied by seat frame A when the structure is arranged as a davenport.

The under frame or box-frame A comprises suitable side members I, front and back members 2 and 2 and a bottom 3. If so desired, the box-frame A may be employed for the storing of bedding.

The seat frame B is shown as comprising a bottom front member 12* anda bottom rear member 12, a front board 12 attached to the bottom member 12*, and sides 10 connecting the bottom= rear member 12 and the front In connection with the back, mattress frame and seat frame, a sliding carriage may advantageously be employed preferably in the form of channel irons 9, from which the said back, mattress frame and seat frame receive support through suitable connections hereinafter described. The tops of the sides 10 I may be higher than the top of the front board 12*, as clearly shown in Fig. 1.

The davenport back D comprises upper and lower members 15 and 15 and side members 16 and 16*, connecting the members 15 and 15 The sliding seat frame B may contain springs 17 (Fig. 2), which may be box springs or any other springs suitable for the purpose of supporting an overlying mattress resiliently. I prefer to use a double mattress 18 the parts being folded upon each other when the bed is converted into a davenport, as shown in Fig. 2, and spread apart to form an open bed surface, as shown in Fig. 3. The line of folding of the mattress,

it will be observed, is at the back, atthe angle of the seat and back, the mattress thus opening at the outer edge of the seat. The upper section of the foldable mattress 18 is suitably fastened to the normally under side of the swinging mattress frame C, by attachment to the side members 19 of the said frame. The upper surface of the top mattress fold carried by frame C is in the form of a seatcushion 50. The davenport back D is provided with a pad 21 which is secured to the frame members 15, 15 16, 16 in any suitable manner, and made resilient by means of springs (not shown) in any approved manner.

A carrier means for the superstructure is shown in the form of slides composed each of channel irons 9 on which the seat frame, back and mattressare mounted in a manner hereinafter described. The channel irons 9 are supported and guided in the following manner: Each of the side members 1 of the base or under frame A is provided at its top with a groove 4. A system of friction rollers, separately shown in Figs. 6, 7, 8, 9 and 10 are provided. There are two sets of these rollers, consisting each of two pairs, two pairs being attached to the under frame A, the other two pairs to the slides 9. Each pair of rollers comprises one roller rotating horizontally and another roller'rotating vertically. The two pairs .of rollers 5 and 5 of the under frame are mounted, each pair on an angle plate 7 which is fastened to the side member 1 of frame A, by means of screws 8 (Fig. 6). The roller 5 turns on a horizontal axis and is journaled in the vertical member 7 of the angle plate 7. The roller 5 turns on a vertical spindle secured to the horizontal member of the plate 7 The two pairs of rollers 5 and 5 are received in the channel irons-9. The inner end of each channel iron 9, as shown in Fig. 8, carries a pair of rollers 13 and 14, the roller 13 turning on a horizontal axis, and the roller 14 on a vertical axis, both being received in a groove 4 of the under frame A. The rollers 13 and 14 may be conveniently carried upon a plate 15 riveted to the channel iron. As a result of this double system of rollers, it is evident that the slides 9 carrying the superstructure can be drawn forward upon the under frame A or pushed back with ease. As the slides 9 travel forwardthe rollers'13 and 14 travel with them in the groove 4, the roller 13 absorbingthe vertical friction and the roller 14 the horizontal friction. Similarly, the rollers 5 and 5 secured to the stationary under frame absorb the-vertical and horlzontal friction of the slides as they travel back and forth.

To the inner end of each channel iron 9 a post 20'is'fastened, as shown in Figs. 4, 5 and 10. Upon the post 20 the seat frame B, the mattress "frame C and the davenport ,back D- all swing. To the inner face of each side member 10 of the frame B, a metal strap 21? is fastened near the top, the inner end of the strap 21* being-pivotally connected with the post 20 as at 22. The frame B has a limited'swinging movement around this pivot 22 in order that access may be had to 'the'st-ationary under frame or boxframe A to remove the bedding therein contained, as shown in Fig. 12. The upper end of the post 20 is offset rearwardly. To the offset- 20 of each post 20a lever 23 is fulcrumed to the side members 19 of the mattress frame C, as at 24. The lever 23 is articulated for a purpose that presently will appear, the end 26 being pivoted at 27 and the downward movementof the end 26 being limited by a stop pin 25. To the side members 16, 16 of the davenport back frame D metal straps 28 are secured; each metal strap 28 is provided with a roller 29 adapted to rest against the end 26 of lever '23 and to swing said lever 23 on'its fulcrum and thus raise frame C when the back D is thrown down into horizontal position. The lower end of each strap 28 is bent to form a curvedarm 29 which is connected with the post 20 by a pivotal connection 30. One end of a bent link 31 is connected with each lever 23 by a pivot 32, and at the other end with a leg'33 by means-of a pivot 34. Each leg 33 is formed with a short angularly-disposed member 33 which swings on a block 33" attached to the side member 10 of the seat frame B, around the pivot 35.

In converting the davenport into a bed, the mattress frame C is drawn forward by hand, thereby carrying with it the davenport back D and the seat frame B. Simultaneously with this forward movement the mattress frame C is lifted, so that the back drops into horizontal position by its own weight into the position previously occupied by the seat frame B, the mattress frame C at the same time dropping on the lowered back. In this position of the parts, it will be observed that the seat cushion 50 is completely reversed in position and lies on the back cushion 21, and that the two sections of the mat-tress 18 are spread apart and lie in the same horizontal plane, thereby presenting a bed surface. As the davenport back thus swings downward and backward, the rollers 29 on straps 28 of back D press downward on the end 26 of the lever 23. Hence, as the back D s'win s downward and backward, the mattress rame C is simultaneously caused to swing upward to the position shown in dotted lines in Fig. 5. The mattress frame C is thus elevated without undue muscular effort upon the operators part, inasmuch as the davenport back and the mattress frame C are in effect counterbalanced during the entire downward movement of the davenport back, because it will be observed that the weight of back D is on the shorter arm of lever 23, while the weight of the mattress frame C.and the mattress fold carried thereby act on the longer arm of said lever. When the mattress frame C reaches the position which is shown in Fig. 5 in dotted lines, the force of momentum usually carries it over the verticalline sot-hat it falls onto the davenport back 'D, and the mattress 18 is spread open in the position shown in Fig. 3. As the davenport back swings downward, the bent link 31 is thrust forward and rocked on the pivot 32; as it does so, the leg is caused to rotate upon the pivot 35 so that the legs are thrown outward and downward until they assume the supporting position shown in Fig. 5.

' In converting the bed into a davenport, in other words, to throw the parts from the posltion shown in Figs. 3 and 5 to the position shown in Fig. 2, the series of operations 18 reversed. The mattress frame C is first lifted to the position shown in dotted lines in Fig. 5, an operation which is compara tively easy because of the light weight of the said mat-tress frame C. When the mattress frame C is in the position shown in dotted. lines in Fig. 5, the ends 26 of levers 23 are brought against the rollers 29. By now swinging the mattress frame C forward and downward the back D is simultaneously raised, the leverage and weight of the mattress frame C assisting in this elevation of the davenport back D, by counterbalancing same. As the davenport back D rises into the position shown in Figs. 2 and 4, the link 31 is drawn backward, thereby causing the leg 33 to be drawn up into the position shown in Fig. 4.

When the seat frame B is lifted upward to give access to the box A underneath, it is desirable that some means be provided to support the back D in the position shown in Fig. 4, because it will be observed that the mentioned articulation between the body of lever 23 and its end 26, causes the lever to flex at its joint, as in Fig. 12, thereby withdrawing fromthe seat back the support afforded by the rollers 29 hearing on the unyielding lever arm 26. Accordingly I employ an extensible support which consists of two pairs of links 36 and 37, each pair connected by a pivot 38, the link 36 of each pair being connected with the under frame or box frame A by a pivot 39 on the outer end of a metal strap 40 secured to the back board 2 of the under frame. Each link 37 is in turn connected with the member 15* of the davenport back frame by means of a pivot 41. A transverse rod 16*, connecting the sides 16 and 16 of the davenport back frame, is adapted to press outward against the links 37, and upon the return movement, to be pressed against by said links. When the parts are in the position shown in Figs. 1 and 12, the bar 16 rests against the links 37, and then supports the back in an approximately upright position, and from said figures it will be understood that with the back D in its rearward, approximately up right position, said back if tending to swing downward, must bear through rod 16 on the folded extensible support 36, 37, so that said back cannot move downward until it is first moved outward on the fixed base. Thus the back cannot fall backward to contact with the wall. It is evident that as the seat back D slides forward upon the base frame A, the links 36 and 37 will spread apart and permit the back to lower, for as the back D is swung down to assume the positioi'f shown in Fig. 5, the links- 36 and 37 will spread still apart, swinging as they do so around their pivots 39 and 41. In'converting the bed-into a davenport, the links 36 and 37 assume the position shown in Fig. 4, after the davenport back D has reached its raised position. As the seat frame D is slid back on the under frame, the links 36 and 37 close up as shown in Figs. 1 and 12.

By referring to Figs. 1, 4 and 5, it will be observed that to the outer end of each side member 19 of the mattress section C an angle iron 42 is fastened, the angle irons 42 being connected by the board 11. It will be observed from Fig. 1 that the top of the board 11 lies below the side members 19 of the mattress frame C. The free space left between the two side members 19 and the board 11, is filled by a downward extension 50 on the front of the seat cushion 50, as appears clearly in Fig. 2. As a result of this construction there is no rigid or unyielding member at the top outer angle of the seat cushion.

In order to support the seat frame and mattress section in the raised position shown in Fig. 12, I may employ any form of brace suitable for the purpose. In Fig. 12, I have 1 shown a preferred form of such brace. This preferred form of brace comprises a long member or leg 43, and a short, doubly bent member 44, the brace being pivoted at 45 to a block secured to the front board 12 of the seat frame B. A link 46 is loosely attached to the end of the short member 44, and a handle 47 is loosely secured to the outer end of the link 46. A slot 48 is cut into the front board 12 of the sliding seat frame B to permit the passage of the chain ,or link 46, and a space is left between the seat frame and the front extension 50 of the mattress frame. When the parts are in their normal position, a pin 49, protruding from the front member 12 'of the seat frame (Fig. 1),

passes through a hole 50 in the link 46 to retain the handle. A recessed block 49, is fastened to the inner surface of the front board 2 of the under frame or box frame A, which block serves as a rest for the member 43 of the brace. When it is desired to lift the seat frame B and the mattress frame 0 in order to gain access to the under frame or box frame A, the handle 47 is pulled a little down and upward to detach the link 46 from the pin 49. By means of the handle 47, the seat frame B and the mattress frame C are then swung up into the position shown in Fig. 12, and the long member 43 of the brace is simultaneously swung outward and made to rest on the block 49 When it is desired to restore the mattress frame C and the seat frame B to the position shown in Fig. 11, the operator lifts the seat frame B slightly by means of its front member 12, so that the long arm 43 is lifted from the block 49". The seat frame B and the mattress frame are then lowered, and simultaneously the long member 43 of the brace 1s swung upward by pulling on the handle 47 and link 46, and is then secured by engagement of the link 46 with the pin 49.

In Figs. 5 and 11 I have shown a pillow support. This support consists of the mem ber 61 hinged at 60 to the mattress frame C, the member 62 hinged at 64 to the link 65 which is hinged at 68 to the seat frame B, and the member 63 carried by the hinged end of the mattress frame, the parts 61, 62 and 63 being pivotally connected as shown at 63, 66 and 67. This support is not claimed in the present application.
