FOLDING COUCH.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed Juiy 16, 1906. Serial No. 326,316.

To all whom it may concern:

Be it known that I, J ACOB' FELDMAN, a citizen of the United States, and a resident of Chelsea, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Folding Couches, of which the following is a specification.

My invention relates to folding couches,

, and consists in sundry structural improvements whereby I attain my object, which is the production of a simple, strong, durable, economically-constructed, and easily-operated folding couch.

While my improved couch is composed of a number of articulated parts, it is nevertheless susceptible of being constructed of the simplest material, such as may be obtained from any ironmongers stock-namely, tubular iron, angle-iron, flat bars, and ordinary rivets. Vithout exception all of the articulated parts of my improved couch are made without the necessity of accurate and expensive machine fitting and can be assembled from made-up stock by a workman of ordinary skill.

In the drawings hereto annexed, wherein like letters are uniformly employed to designate like parts, Figure 1 is an end view of my improved couch, showing the head end thereof in elevation and one of the swinging frames or side extensions in its extended position. Fig. 2 is a section of the couch, taken along the line 2 2 of Fig. 3 looking toward the foot end thereof. Fig. 3 is a longitudinal vertical section along the line 3 3 of Fig. 4, and Fig. 4 is a plan view of the head end of the couch whereon certain portions are broken away to show other parts more clearly.

My improved couch comprises a main frame and swinging frames articulately joined or pivoted at the sides of the main frame, the main frame being provided with suitable head and foot standards, which give attractive and substantial finish to the entire structure and serve as the supports which sustain the couch at a convenient level above the floor.

, The main frame consists of top end bars B and lower end bars B, these being constructed, preferably, of iron-angle. The top and bottom end bars B B .are secured together and braced by vertical metallic slats b, b, N, and b on the head end of the couch and b I) b on the foot end thereof. The slats b b are placed close together with a narrow space between them, which forms a guiding-slot for certain movable members hereinafter to be described. The structure of the couch is symmetrical with respect to a vertical middle plane extending lengthwise thereof, and the movable and articulated parts are duplicated on one side and the other. The two end parts of the main frame, composed of the angle-irons B B and the vertical slats above mentioned, are secured to the head and foot standards A A by means of blocks a and bolts which pass through the blocks, frames, and standards. Each standard A A is formed, preferably, of a single piece of iron tubing bent, as shown in the drawings, to supply upright portions, whereto the blocks a a are secured, a transverse head and foot, and outwardly offset or spreading legs, to which the usual casters may be applied. The outervertical slats b on both the head and foot frames are made referably of angle-iron both for the sake o greater stiffness and strength and also to provide for the movement and securement of sundry articulate and moving parts, to be described. At either side of the main frame side rails C, of angle-iron, extend from the head-frame to the foot-frame, being secured by rivets or bolts to the angle-iron vertical slats b and being further braced by the braces H, which extend from the upper por tion of the vertical slat b in each instance downward to the outer web of the side rails C, to which the said braces are riveted. Cross-braces of angleiron C are provided for the further stiffening of the structure and for proper support for portions of the operating mechanism.

The upper transverse end bars B extend laterally a short distance beyond the blocks a, so as to provide a support for the swinging side frames. These side frames are made with a side rail D, which in the form preferred by me are lengths of iron pipe slightly offset or dropped, as shown in Figs. 1 and 2, and secured by rivets to the angle-iron end bars D. means of pivot-bolts, at cl to the overhanging ends of the end bars B of the main section.

The end bars B of the main frame and end bars D of the swinging side frames are provided with proper means for the seourement of a mattress supporting fabric, such as E, which is stretched under proper tension between the end bars of the couch. I have shown in the drawings a mattress-supportingfabric of These end bars D are pivoted, by

the well-known wire-link construction and for the reason that I believe it to be better adapted than woven wire to the structural peculiarities of a folding couch.

When the folding couch is folded, the side frame swings down to a vertical position, as seen at the right-hand side of Figs. 1 and 2.

In order to elevate and sustain the swinging side frames, I provide the following mechanism: Bars F F are pivoted together at f the bar F being pivotally joined to the end bar D and the bar F being pivotally joined to the vertical slat 6 At its inner end the bar F is bent down, the downwardly-inclined portion being shown at F. Treadles Gare employed to operate the toggle formed by the bars F F. These treadles G are formed by twisting a pair of iron straps into a spiral, as shown best in Fig. 3, and the pair of straps extend from the spiral treadle portion G inward, forming the lever portion G G. Between the two members G of this lever portion there is secured the stirrup G which surrounds by its loop the inclined end F of the toggle-bar F. At the inner end the lever-straps G straddle and are pivoted to the end of the bracket H, which is composed of a short piece of strap-iron riveted to the cross-brace C and bent a quarterturn on itself and then slightly upward, as seen in Fig. 3. Props L, which consist of bent strap-irons, are pivotally secured at Z to the end bars D of therswinging frames, and notches Z are filed at a proper point in the props L. The lateral webs of the vertical iron slats b are slotted at M, so as to form passages for the props L, the lower lips m of these slots serving as catches wherewith the notches Z engage. The toggle-bars F and F are bent or offset, the bar F passing inside the guiding-bar b, which is suitably offset for the purpose.

When it is desired to elevate one of the swinging side frames of the folding couch, the operator places a foot upon the treadle G and bears down upon it, whereupon the stirrup G moving in the space between the upright slats b b, pulls down the portion F of the toggle-bar F and by the action of the toggle throws the side frame upward and outward. The prop L is carried upward by this movement until the notch Z drops over the lip m. The elevating treadles and toggles are lccated only at one end of the folding couch, which I have termed the "head end, although in the couch herein shown there is no substantial difference between the frames and standards at the respective ends of the couch. The props L are provided at both ends of the swinging frames, so that these derive support from the props at both the head and foot ends. As the swing-frames and operating mechanisms are duplicated on either side of the couch-frame, either one side frame or the other, orboth, may be elevated, and the couch may thus be used with these side frames folded or hanging down as a narrow couch or single cot, may be extended to threequarter-bed width by the elevation of one swing-frame, or to double-bed width by the elevation of the other. If, therefore, it be desired to move the couch against a wall an :i keep it there, the outer swing frame may be operated without necessitating the moving of the couch as a whole from the wall.

When it is desired to lower either of the side frames, the tripping mechanism is brought into requisition. This consists of a strap-iron tripper K, which extends from end to end of the couch and has its ends K bent at a right angle and pivoted to the vertical angle-slats at Ir. At the operating end of the couch there is placed the trip-lever J, pivoted to the short strap y" and provided at its outer end with a tread J and at its inner end with a loop J which surrounds the tripper-bar K. Now when the foot of the operator presses down the tread J the loop J is raised, and with it the tripper-bar K, which strikes smartly against the inner end of the prop L at either end of the couch, lifts the notch Z out of engagement with the lip m, and allows the swinging frame to fall to its vertical position.

An ordinary mattress may be laid upon the wire fabric E and, provided it is thin enough for the purpose, will bend of itself so as to hang down at the sides when the swing frames are in folded or in vertical position. If a thicker mattress is desired, this may be made like a book-mattress namely, with sections of sufficient width to cover the swinging frames, said mattress-sections stitched to the binding of the main mattress along the juncture of their lower edges.

What I claim, and desire to secure by Letters Patent, is
