Specification of Letters Patent. Patented May 16, 1911. Application filed November 25, 1910. Serial No. 594,238.

To all whom it may concern:

Be it known that I, ADoLPH C. KLorrmo,

a citizen of the United States, and a resident of Toledo, in the'county of Lucas and State of Ohio, have invented a certain new and useful Sofa-Davenport; and I do hereby declare the following to be afull, 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to sofa or bed-davenports of the reversible seat type and has reference in part at least to improvements upon the forms of davenports of this character described and claimed in my former applications for United States Letters Patent Serial Nos. 572,233 and 587,331, filed July 16, 1910, and October 15, 1910, respectively.

The object of my invention is to improve upon the construction and operation of the apparatus described in my said former applications whereby to enhance the practicability and commercial value thereof, and also to provide a construction of foldable bed frame, which has an'inner frame section carrying afabric bed bottom and capable of removal from the remainder of the bed frame without destroying the efficiency thereof to permit the substitution therefor of a coiled spring section.

A further object of my invention is the provision of simple and efiicient means for acting on the seats of apparatus of this class v to assist a manual turning of the same, thereby lessening or minimizing the labor incident to a turning of such seats.

The invention is fully described in the following specification,- and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,- I i Figures 1 and 2 are vertical transverse sections of a davenport frame withthe bedframe folded therein and a portion of the seat frame of each broken away with the latter inverted. Figs. 3 and 4: are crosssections of the seat-frame in inverted position, with thebed-frame thereof in folded and unfolded posit-ions, respectively. Fig. 5

is aosimilar section of .the seat frame, with the bed-frame folded therein, the inner section thereof removed, and a set of coiled springs substituted for such section and its fabric. Fig. 6 is a plan of an end portion of a seat-frame and bed-frame, with the latter in unfolded position. Fig. 7 is a similar view thereof with the inner section of the bed-frame removed and a set of coiled springs substituted therefor. Figs. 8 and .9 are different enlarged details of the. pivotal seat supporting parts. Fig. 10 is an enlarged section on the line a? w in .Fig. 6, and Figsull and 12 are details of the intermediate bed-frame sections.

Referring. to the drawings, 1 designates the ends of a davenport, and 2 the back thereof, which parts may be of any suitable construction. The usual seat frame, having the end pieces 3, 3, and the front and rear side pieces 4 and 5, respectively, is mountedbetween the ends 1, 1, of the davenport, frame in a suitable manner to permit it to be turned or inverted as is common in davenports of this class.

While the seat frame may be pivot-ed in any suitable manner within the davenport frame, a preferable manner of mounting the same for such purpose is as follows: Plates 6 are secured to the outer sides ofthe seat frame ends '3, and each of such plates has a pivot stud 7 projecting therefrom and shown in the present instance as being provided the davenport frame. The stud 11 is so displate 6 is also proposed relative to the stud 7 that when the associated seat frame is in normal or closed position, as shown in Fig. 1,the stud 11 is positioned in advance of the stud 7 in substantially a horizontal plane therewith, and when the seat is inverted the two studsstill stand in a horizontal plane with the stud -11 to the rear of the stud 7, as shown in Fig. 2.-

Upon swinging the seat frame from normal to inverted position, the operator raises the front side thereof, thus causlng the stud 11 to rise in its guide slot 12 and the pivot stud 7 to move to a vertical plane with the stud 11. Upon a continued turning of the seat frame-the stud 7 continues its forward movement and the stud 11 moves downward in its slot until the two studs assume the position shown in Fig. 2. To permit a raising of the stud 11 from normal position the plate 10 is provided in its upper portion with a centrally disposed opening 14 leading to the race 9. The upper end of the guide slot or race 12 is enlarged, as at 15, above the normal limit of raising movement of the stud 11 whereby upon a bodily raising of the plate 6 a slight distance when in upright position, the flange of the roller 8 is disengaged from the lower coacting edge of the plate 10 and the enlarged inner end of the stud 11 stands in register with the opening 15, thus permitting a disengagement of the plate 6 and its studs from the cooperating guide plates 10 and 13.

To facilitate a raising of the stud 11 and the associated end of the plate 6 from reclining position, a coiled compression spring 16 is mounted beneath the enlarged end 11 of such stud\ with its upper end thrust thereagainst, as best indicated in Figs. 8 and 9. The spring 16 is disposed in the lower portion of the space provided between the two uprights or posts 17, which are secured to the inner sides of the associated davenport frame ends 1 and have the plates 10 and 13 secured thereto. A plate-18 is secured to the uprights 17 to close the open side of said space without the spring 16, and a plate 19 is secured to the lower ends of the uprights 17 to support and receive the lower end thrust of said spring. The springs 16 are not of themselves of sufficient power to alone raise the studs 11 and the weight of the associated portion of the seat frame to which such studs are subjected, but are intended to assist very materially in such raising operation, as it is only necessary, with the use of such springs, to exert a very slight raising pressure on the forward edge 4 of the seat frame when in normal position, as shown in Fig. 1, to invert such seat, or to exert a very slight lowering pressure on the rear edge 5 of the seat frame when in inverted position, as shown in Fig. 2, to return the seatframe to its normal closed position, for in either case the springs exert a raising pressure upon the studs 11. Vhile it is preferable to employ the springs 16, to assist in turning the seat-frame, they may be eliminated from the construction without eflecting the operation thereof other than to render a turning of the seat frame more difficult.

Rising from the upper edge of the rear piece 5 of the seat frame, when in inverted position, adjacent each end thereof, are the spaced standards 20, 20, the outer ones of which standards are shown 'in the present instance as being bent upwardly from the ends of an angle-iron bar 21, which is secured to the seat frame piece 5, .while the inner ones of such standards fixedly rise from said bar but are not integral therewith. A brace 22 is attached to the bar 21 and to each of the uprights 20 of a set to brace said uprights and bar against relative movements. A pivot bolt 23 is shown as connecting the upper ends of the uprights 20 of each set, and pivoted at their inner ends to each of these bars are two substantially duplicate bed-frame parts or sections 24 which are of broadened channel form with their flanges disposed upwardly and the inner or contiguous ends thereof projected beyond the bodies of the respective parts and lapping each other to receive the pivot bolt 23, with the flange ends of the part 24 preferably projected within the other. \Vhen the parts 24, 24 are in longitudinal register their contiguous body ends abut and stand in a common plane. To the outer or free ends of the inwardly projecting parts or sections 24 are pivoted the side bars 25 of the inner section of the bed-frame, which bars are connected at their inner ends by the cross bar 26, while the outer or free ends of the parts or sections 24 are pivoted to the inner ends of the side bars 27 of the outer bed frame section, said side bars 27 being connected at their outer ends by a cross-bar 28. The bars of the inner and outer bed frame sections are preferably, but not necessarily, of angleiron form with their outer flanges projecting upwardly and those of the side bars 25 and 27 pivoted, as at 29, to the outer flanges of the respective frame parts 24, 24. The purpose of axially broadening the pivotal bearings or inner ends of the parts 24, 24 is to resist an inward collapsing of their outer ends due to strain exerted thereon, or on the inner ends of the attached bars 25, 27, by the bedbottom fabric.

The bed frame parts 24, 24', have the outer ends of their outer vertical flanges lapping the inner sides of the vertical flanges of the respective bars 25 and 27 with the outer ends of their bodies or horizontal flanges positioned to abut against the respective horizontal flanges of the bars 25 and 27 when the bed-frame is in horizontal or unfolded position, as shown in Fig. 4, thus serving to limit the unfolding movements of the frame sections. The outwardly projecting sets of sections 24' of the bed-frame have the outer ends of their outer vertical flanges cut on a bevel, as indicated at 30. Figs. 4 and 12, to adapt them to coact with the horizontal flanges of the attached bars to limit the relative folding movements of such bars, as shown in Figs. 3 and 5.

In order that the relative pivotal movements of the intermediate bed- frame sections 24, 24, may be limited, the inwardly -projecting ones thereof have the inner or bed-frame, have turned a predetermined dis tance relativeto the sections 24, their bodies or horizontal portions will coact with the beveled ends 31 of the sections 24 to cause such latter sections to turn therewith during the remainder of their folding or pivotal movements. When the sections 24, 24 have turned suificiently to place the inner ones thereof in vertical position, such inner sections coact with the associated braces 22 to limit their movements, while the outer ones of such sections are tilted inwardly toward the opposite or front side 4 of the seat frame. as shown in Figs. 2, 3 and 5.

Upon a folding of the bed-frame the inner section 25-26 thereof lowers within the seat frame due to its pivoted end being carried downward by the folding action of the frame sections 24 and its free or outer end traveling down the incline tracks 32, as described in my former application, Serial No. 572,233, filed July 16,1910. The outer bed-frame section 2728 has supporting legs 33 pivoted to the outer end portions thereof, which legs fold up with said sections in substantial parallelism with the inner bed-frame section 2526 upon a folding of the bed-frame, as indicated in Figs. 3 and 5.

34 designates an angled locking member, which may be carried at one or both ends of the seat frame and coacts with the outer bed-frame section 27-28, when folded, to retain it in such position, as shown in Fig. 3. This locking means is fully described in the application above referred to.

The bed-frame is provided with a suitable fabric or netting 35 which is attached to the horizontal flanges of the bed-frame bars in any suitable manner, as is apparent. In the use of beds of this character it is frequently desirable to substitute a set of coiled springs for the portion of the bed-frame and fabric 35 disposed over the seatrfram'e, as

the fabric is apt to sag, especially when subjected to heavy weight, to such an extent as to strike the subjacent frame parts."

With the construction of bed-frame above described, the bed-frame sections 24 and attached sections 2526, with the attached fabric, can be removed for the purpose of substituting a set of coiled springs 36, therefor, by simply disengaging the sections 24 from the pivot 23 and separating the fabric 35 along its central longitudinal portion. This belng done the frame parts 24 and 25-26 with the attached portion of the fabric 35, are removed and a set of coiled springs 36 mounted in a suitable manner within the seat frame, as upon cross-bars 37 secured thereto, as shown in Figs. 5 and 7. It is thus apparent that it is possible with my improved bed-frame to either use an entire fabric bed-bottom or to easily and quickly remove a portion of the bed-frame and fabric and substitute therefor a set of coiled springs, so as to provide a combina- 1 'tion coiled spring and fabric bed-bottom. l/Vhen the inner bed-frame sections 24 and,

2526 are removed the inward tilting of the sections 24 when the bed-frame is folded, as shown in Fig. 5, is limitedby reason of the beveled edges 38 of the inner ends of their flanges striking the braces 22.

It is apparent with my improveddavenport-bed that to invert the seat to permit an unfolding of the bed-frame it is only necessary to exert a slight raising pressure upon the front side 4 of the seat frame so as to cooperate with the raising springs 16 to raise the seat frame to vertical position, and that when the seat frame has been turned past such vertical position a sufficient downward pressure must be exerted on the front side 4 thereof to cotiperate withthe weight of such side to lower the frame to horizontal posi-c tion against the tension of the raising springs 16. The seat having been inverted, the bed-frame is easily unfolded by grasping the section 2728 thereof and lifting it upwardly and outwardly. WVhen the outer section 2728 and intermediate sections 24, 24, upon an opening of the frame, move into longitudinal alining position, such sections, upon a continued opening movement of the bed-frame, act on the inner section 25-26 to raise it to its normal position in a horizontal plane with the other bed sections. It is also apparent that the .broadening of the inner ends of the sections 24, 24, gives them a broad bearing surface longitudinally of the frame upon the pivots 23 so as to brace such sections against inward collapsing movements due to an inward pressure being exerted on their outer ends by the attaching of the fabric 35 to such sections and to the frame bars 25, 27.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what I claim as new anddesire to secure by Letters Patent, is,-
