be it lmo Ythat we, lln FnnnnMAN and Flai u lid. l` t tu citizens 0f the llnited States, and residin at Chicago, in the county of Cook and` have invented certain new and useful linprovements in ed Structures for Davenports, of 'which the following is a specication.

flur present invention has special reference to the structure for` davenport beds and the mer of the assembly of the bed structure with the davenport 'lhe bed structure inust be capable of folding the seat portion of the davenport when the same is closed, and when folded should provide sumcient room intermediate the respective sections for ed'ectively accoodat the .desired t y and llhe special objects of our present invention are to perfect the instrumentalities by means of which the fol 1| 1 and unfolding of the sections may be eifected so as to secure a sterl and more rigid structure in both open and closed positions, so asto perfect its ease of operation and so as to Simp its anufacture and economize its cost.

other object of our invention is the provision of automatically operable legs, ple in structure and operation, which will support the outer ends of their respec- 'l sections When the same are in hiv@ l u ""1 their le or olded positions, said legs being adapted to fold back adjacent and substantially parallel to their respective sections when the same are in their closed or folded positions.

fn l another object of our invtion is the provision of such a fol bed structure ui a foot-rest or bracket, which may be et do upon the mattress and bedding for the pose of hol the same in position when not in use.

h i i it object is the provision of simple i uhby e out/er n section sp up when folded upon the intermediate son, lbe positively spaced therem and loclred in substantially parallel relaon thereto, andthat vvhenthe two sections so lare folded upon the third or rear section of sprl@ the same will again loch d all be spaced hom and in subd pel relation to the third or i section, and eA several sections so tate of ois, v

folded will be held posihively vvithin the body of the seat portion f the davenport, prlor to and during the revolving thereof.

A still further object of our invention the provision of means for the positive loclrmg of the rotatable seat portion of the davenport to the rigid bach and ends thereof during the process of folding or olding of the bed sections d after the revolving of the seat portion to fo the seat for the davenport. n

Similar reference characters refer respcctively to similar parts throughout the several views.

-Our improved. bed structure comprises three mattress sections, namely, an outer section 14, an intermediate section 13, and a rear section 0, the latter being suitably supported within the seat portion D of a davenport bed, as will hereinafter be more fullyv set forth.

The outer section A comprises a single end rail 1, being bent back at right angles to itself at each of its ends, to form side rails 2 2. This rail is preferably made from L- section angle-iron, with one flange or web thereof disposed horizontally and extendin inside of the frame, the other flange or we extending vertically as shown and to make the bends at the juncture of the end and side rails, the horizontal flange is notched, as at a1. The intermediate section B is comprised of two side rails 3 3 of angleiron of similar cross-section to the angleiron of the outer section, and the rear section C of the spring is constructed similar to the forward section 14, having its two side rails 4 4 corresponding to the side rails 2 2, and its head rail 5, corresponding to the foot rail 1. These three sections are hinged together, as will be described, and stretched between the members constituting the frame, namely 1, 2 2, 3 3, 4 4, and 5, is a suitable wire fabric or mesh S held to the frame through the instrumentalities of the helices Sa.

The bed structure as a unit is secured to the seat of the davenport by means of a stardard `comprising a longitudinally disposed brace 6, adapted to lie adjacent the seat structure D of the davenport and to extend transversely thereof, said brace 6 being bent upward at its ends (Fig. 14) and then back parallel to itself and being rigidly secured to the seat structure by means of brackets D1 (Figs. 13 and 14) secured to said seat structure and Supporting said brace 6 at its inclined ends. At the opposite ends of said brace and by means of pintles 6a 6, are pivotally mounted the rear ends of the side rails 3 3 ofthe intermediate section,

the horizontal flanges thereofv being cut away at their ends to permit the standards to come upon the inner surface of the vertical anges, as shown in detail in Fig. 10 of the drawings. t

To the vertical flanges 'ust referred to, and just in front of their pivotal connection 6", are pivoted hin e-plates 7 7 by means of suitable pintles -T, said plates bein sufliciently long to extend rearward beyond the connection between the rails 3 3 and the brace 6, and to this end and in line with the pintles just described, is pivoted at 7bb the forward ends of the side rails 4 4 of the rear section C.

Stops 8 8 are provided on the inner face of and in the upper part of the plates 7 7 to contact with the rails 3 3 when the rails have been swung to their fully open position, and headed pins 9 9 are provided upon the inner ends of the plates under the heads of which the vertical flanges ofthe forward ends of the rails 4 4 extend, these pins 9 9, coperate with the pivotal connection between the hinge plates and the rails, to resist the pull or tension of the wire fabric and also to form a double bearing for the rails 4 4.

The pivotal connections between the outer frame A, and the intermediate frame B, consist of links or plates 10, (Fig. 11) the ends 10a of which are at right angles to the tops thereof, and have their lower corners 10b, rounded, said rounded corners being adapted to permit the horizontal flanges of the said rails to swing about the pivotal connection. These plates extend between the rear ends of the rails 2 2 and the forward ends of the rails 3 3 and are pivotally bolted thereto at 11 and 12 as shown, and midway-between the pivotal points, is loosely mounted or journaled a cross-bar or rod 13, adapted to act as a brace and spacer for retaining a uniform distance between the pivot plates 10 10, and adding to the rigidity of the structure as a unit.

To positively support and secure the necessary movement of the rear section C, we provide a toggle comprising the links 14 15, pivoted together at one end, the other ends of which are respectively pivoted at 16 and 17 to the seat structureof the davenport and the rear of the end rails 4 4. Running from its pivoted connection between the links to a suitable point on the hinge-plate 7, is pivoted a link 18.

For the purpose of supporting the outer end of the intermediate section B, when in open or extended position, we pivot to the forward ends of the end rails 3 3, legs 19.

land just below this pivotal connection, and

to said leg, is pivoted a link, 20, the other end of which is pivoted to the forward depending end of the plate 7. For the purnaeaere pose of supporting the outer end of the outer section A, when in a like extended position, we provide similar legs 21 21, pivoted to the forward ends of the end rails 2 2; and at a point below this connection, and to said leg, is pivoted a link 22, forming one end of a toggle, the opposite end thereof, consisting of a link 24, is pivoted to approximately the center of the end rail 2 as shown; and running from the pivotal connection between the links 22 24 to a suitable point on the leg 19 to impart the necessary movement to the toggle, is a link 23.

Substantially.. parallel to the end rail- 1, of the outer bed section A is a head or foot rest, comprising a suitably braced U- shaped wire member 25, secured and journaled to pieces of angle iron 26 26, riveted to the rail 1, in (Fig. 12) one end of the U-shaped member 25, being bent at substantially right angles to the'plane thereof, and to this end 25 is secured one end of a coiled spring 27, the other end of which is connected with the horizontal flange of the rail 1.

1t will be seen that when the foot brace or member 25 (just described) is extended, the spring will hold the same in extended position, and that when closed, the rightangled arm 25aof' the member 25 will be carried across the dead center, and will therefore hold the foot member in closed position, so as to hold the bedding in position during the folding of the bed section.

1t will now be apparent from the foregoing detailed description of the bed sections, together with their manner of connection, and with reference to Fig. 1 of the draw.- ings, that as the folding operation is commenced, the sectionl A, first pivots at 11, as shown in dotted lines in Fig. 1, the link 23 breaking the toggle 22 2f1,l and causing the legs 21, to commence their fold. After reaching this position, the ends 10a of the links 10, 4abut against the horizontal flanges of the rails 2 2, and cause the hinge or plate members 10, to pivot at 12 on the rails 3 3, thus forming a square bend as shown completed in Fig. 2, the legs 21, being folded back substantially parallel tothe side rails 2 2, together with the links 22 and 24:. lBy this construction, the initial folding movement of the forward section causes im,-`

mediate sharp turning or folding movement of the leg 21, instead of a very slow initial folding movement such as would be produced if the leg were controlled` by a link extending from the leg to one of the sections.

1n order to hold the free end of section A in spacedk relation to the section B, and

the section litself in substantially parallel relation to the intermediate section, we provide spacing arms or brackets 28 28, rivstantially eted to the 21, at a' point below their pivotal connection with the raills 2, the

opposite ends of said brackets being grooved sirable to facilitate the comp ete foldi of the" structure and to assist in the retaining of the bedding in position, -we provide a lock comprisin a'substantiallly 1li-shaped bolt 30, the shangk of which is ada ted to be Journaled to the bracket 28, and t e ends thereof 30a adapted to rotate to positions adJacent under and over the respective lianges of the end rails 2 and 3 as clearly shown in detail in Fig. 8. A modified form of locking device is illustrated in Figs.V 5 and 6, the brackets 28, being similarly secured to the legs 21, the protruding ends of said arms, however, being somewhat spear shape in contour, and being notched on one side .of the spear-head en d to engagethe protrug lug 29 on the slidably mounted on ythe rai1 3 adjacent the 4in this position, the same bein found de-A l A sprlng actuated slide plate 31. isv l lug 29, and normally held m engagement therewith by means of a contraction spring 32, one end of which is secured to the rail,

and the other end to the pintle or bearing' of the plate 31, which is adapted to extend through and slide within a horizontal slot or guideway 3a in the rai1 as shown.

`llt will be seen with reference to Figs. 5 and 6, that when the head of the arm 28 is closed down upon the sliding member 31,

'the spearf striking the point of contact between the pin 29 and the sliding member 31, said member will be forced back, 'allowing the head to enter the passage-way thus formed, until the recess on the edge of the spear head engages the pin 29, then due to the action of the spring 32, the arm 28 is yieldingly held in engagement with the pin, and until a slight'upward pull is exerted by the operator upon either the rails 2, or preferably upon a convenient form of handle such as shown at 33, the two sections will remain firmly locked.

After locking the sections` A B as described, the structure thus formed is raised at its outer end, pivoting on the bolt 6 of the brace 6, to the position shown in dotted lines in Fig. 2, and after reaching this position, the sections just referred to pivot again, and this time upon the bolt 7a, of the plate 7,

ree

dropping down within the seat structure D and adjacent the rear section. C and subparallel thereto, as cllearly 'shown in Fig. 3, the legs 19, folding up adjacent and substantially arallel to the rails 3 3. The rear section is also dropped due to the action of the plate 7 and the toggle joint llt-15, this last a von, however, is more seat structure, and has itstop adapted to extend over the horizontal iange of the s ection B, as shown, and its lower end being pivoted to a transverse Slidable rod 35 (Flg.

'4) the other end of which is adapted to enter a recess in the wall vor stationary portion of the davenport, when the lock is open, for the purpose of locking it against the further rotation of the seat structure. The bolt 35 when the springs are folded and locked is withdrawn from engagement with the seat structure.

After the final folding and locking of the bed sections and the unloclng of the seat structure from the frame` of the davenport, as vjust described, the seat structure is revolved upon a system of pivots and levers, preferably as described and claimed in our application filed June 19, 1912, Serial No. 704,493, and which we do not deem it necessary to either describe or again claim in connection with our .present application. However, after the revolving of the seat structure to form a seat for a davenport, the same is locked in this position from further rotation by means of a spring lock as shown in Fig. 9, consisting of a back plate 36, adapted to be fastened to the upper rear corner of the rotating seat, said plate sup porting a catch or spring actuated engaging pawl 37, adapted to engage a pin 38 secured to and protruding from-the side arm of the stationary portion of the davenport, and said pawl being adaptedl to be drawn out of engagement with the pin and against the tension of the spring by means of a suitable preferably flexible handle 39, adapted to pass up from behind the seat structure and in front of the upholstery of the back of the davenport, and to beaccessible but not conspicuous.

It will now be apparent from'the foregoing speciiication that we -have provided a bed structurecomprising a three section mattress employed in the construction of ah davenport bed, embodying two sections adapted to fold upon themselves and then as a unit to be folded upon the third section, at all times allowing sufficient room for the necessary bedding, and providing ample means f or making it a complete rigid structure, simple in operation and. positive in its movements. v
