ALBERT BUTZER, OF DEER PARK, WASHINGTON.

EXTENSlO N-BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 573,390, dated December 15, 1896.

Application filed March 6, 1896.

To all whom it may concern.-

Be it known that I, ALBERT BUTZER, a citizen of the United States, residing at Deer Park, in the county of Spokane and State of WVashington, have invented certain new and useful Improvements in Extension-Bedsteads; and I do hereby declare the following sents a detail central vertical section through one of the corner-posts. Fig. 3 represents a front elevation of one of the rack-bars. Fig. 4 represents a side elevation of the bed in its closed position, one of the head corner-posts being broken away to expose the rack. Fig. 5 represents a detail central vertical section through one of the corner-posts, showing a modified form of adjusting devices for adj usting the ends of the lazy-tongs. Fig 5 represents a top plan view, partly in section, of the device for throwing the rack-bar back out of its normal position. Fig. 6 represents a similar view of the key for operating the same. Fig. Trepresents a side elevation of another form of my bed in its opened position. Fig. 8 represents a side elevation of the same closed. Fig. 9 represents a side elevation of yet an- Fig. 10 represents a front elevation of the same. Fig. 11 represents a detail central vertical section through the upper portion of the head of the construction shown in Fig. 9 and Fig. 12 represents a side elevation of my improved mattress.

A in the drawings represents the head of the bedstead; B, the foot; 0, the sides, and D the spring-supporting slats or bars.

In the constructions shown in Figs. 1 to 5, inclusive, I have shown my invention applied Serial No. 582,108. (No model.)

to an iron bedstead. The head and foot portions in this form of my invention are of any usual ornamental construction ordesign and are put together in the usual manner, with the exception that the corner-posts a a b b are each hollow and provided with a vertical slot at a b b in their respective inner sides. These slots are for the accommodation of the ends of the bars a of the lazy-tongs sides 0, which will be hereinafter more particularly described. Each of the head corner-posts is provided with a rack-bar f, supported therein by a lateral pin f, that passes loosely through the upper part of the same and prevents all vertical movement of said bar, but permits of horizontal movement back and forth. The

said rack-bar f is approximately semioylindrical in cross-section and has the upper and lower portions of its straight vertical edges formed with rack projections f Vertical slots f f are also formed in the wall of each of said racks to permit full play of the ends of the bars of the lazy-tongs. Cross-bars f f are set in said rack-bar across the upper end of one of the slots f 3 and across the lower end of the other. These bars brace the rack and form firm seats, against which the notches 0, formed in bars 0, rest when the lazy-tongs are fully extended. The said rack-bars are each held normally forward against an adjusting-piece H by bowed springs f f, attached to the rear of the rack-bar and bearin g with their free ends against the rear inner wall of the hollow post.

The adj ustin g-piece H,that is adapted when.

rotated to throw the rack-bars back against the action of the springs, consists of a disk h, mounted on a pin it, that is journaled. in the sides of the hollow post and provided with a squared aperture 72. at one end. The pin h is rotated to operate the disk h and throw the rack-bar back against the action of the springs by a key I, having an operatinghandle 2' and a squared end i, that is adapted to engage the recess in the end of the pin h. A pin f projects across through the lower part of each post to prevent the lower end of the rack-bar swinging too far forward.

The slides O of the bed, as before explained, are formed of the ordinary construction of lazy-ton gs composed of pivoted bars 0. Each bar at each end of each side is slightly longer than the bars composing the remainder of the side, and the head-bars are each provided with a lateral pin 0 that is adapted to en gage the projections of the rack-bar in the post and thus hold the lazy-tongs in any adj usted position and regulate the length of the bed.

The hollow foot-posts are provided with cross-pins f f against which the ends of the lazy-tongs levers rest when in their open and closed positions, respectively. The end of each lever that enters the foot-posts is provided with a cross-pin f to prevent its pulling out of the post.

Brackets (Z are pendent from the pivots of the bars of the lazy-tongs and support the slats D, upon which the spring-mattress is supported. Each of these brackets comprises an arm extending from the pivot-point cl of each pair of levers of the lazy-tongs. Two arms extend from each pivot-pin. One of said arms is loosely mounted on the pin, but rigidly connected to one of the tongs levers, while the other is rigidly mounted on the pivot-pin, which is in turn rigidly connected to the other of said pair of lazy-tongs levers. The result of this construction is that as the levers of the tongs open and close each pair of brackets does the same. Each bracket always follows and occupies the same relative position to the lever to which it is attached. By providing two brackets to each pivot of the lazy-tongs the slats can be placed closer together than would otherwise be the case. The brackets by moving with the levers do not interfere in any manner with the folding of the bedstead. By forming the end bars of the series composing the lazy-tongs longer than the remainder of said bars a greater amount of leverage and consequential strength is secured at the ends of the sides, where it is most desired.

In Fig. 5 I have shown a modified form of adjustment for the ends of the rack-bars,consisting of sliding blocks P, mounted in said hollow head-posts and communicating with the ends of the tongs by thumb-bolts p,passing through vertical slots in the walls of the posts.

'Said thumb-bolts are tightened against washersp interposed between the heads of said bolts and the posts and the ends of the tongs thus held in position.

It will be observed from the above that the bed can be adjusted to any length desired at will and locked in such adjusted position by means of the rack-bars or the devices shown in Fig. 5. The folding spring-mattress shown in Fig. 12 consists of two half-mattresses .I J of any well-known construction. These are hinged together bysuitable hinges j, and one of said sections is provided with a handlej, by means of which the mattress can be lifted at the middle, the two halves naturally falling together into a compact bundle, which can be stored away into any convenient corner. The head and foot portions of the bedstead are provided with pivoted catches 7' that are adapted to engage suitable projecting studs j on the sides of the mattress.

In the construction shown in Figs. 7 and S I have applied my invention to an ornamented form of folding bed, representing a wood mantel. The head portion in this case is provided with a hinged mantel-top K and hinged front K, and with side ornamental panels k, and W. The foot portion is provided with a panel 70 \Vhen the bed is closed, as shown in Fig. 8, all of the panels fit snugly together, forming a very ornamental panel. When the bed is to be used, it is first extended, the panel 70 removed, and the top K and front K turned up into the position shown in Fig. 7. In all other respects this form of my invention is the same as that illustrated in Figs. 1 to 5, inclusive, suitable slots being cut in the wooden end posts to accommodate the rack-bars.

I'Iooks M are provided on the head and foot portions of the bedstead and are adapted when the bed is extended to engage suitable eyes or studs m on the mattress-supporting slats, and thus hold the bed together.

In Figs. 9, 1.0, and 11 I have shown still another form of my invention, comprising an extensible bedstead adapted to be folded into another form of ornamental mantel. This form of my invention consists of head and foot portions N N and hinged top, front, and side pieces 01, n, and 91 respectively. The top a is hinged to the top of the head of the bedstead and the front or to the free edge of the top. The sides 07. are hinged to the respective ends of the top and are each provided on each side with a headed projection 41 These headed projections fit into T- shaped or dovetail grooves n a formed in the head portion and the front n, respectively, and thus when the bed is closed all of said parts are held firmly together. A block D is secured to the inner side of the front at andfits into a suitable recess in the foot portion when the bed is closed, whereby the head and foot portions are caused to register one wit-h the other. Then the bed is opened, the top, front, and sides fit snugly against the wall, lapping over each other, as shown in dotted lines in the drawings.

lVith any of my forms of bedstead the bedclothes and mattress can be stored away i11- side, between the foot and head portions, in a very convenient manner.

My bedstead is also very desirable in form and construction, and when closed occupies very little space and can be stored away in any convenient corner.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an extensiombedstead, the combination of head and foot portions, sides formed of lazy-tongs said head and footportions being provided with vertical slots for guiding and bracing the ends of the lazy-tongs and permitting of their adjustment up and down to lengthen or shorten the sides of the bed to different degrees, and means for locking the ends of the lazy-tongs at diiferent points in said slots, substantially as described.

2. In an extension-bedstead, the combination of head and foot portions, sides formed of lazy-ton gs, and rackbars in the head and foot portions adapted to be engaged by the ends of the lazy-tongs whereby the length of the sides may be adjusted at will and said sides locked in their adjusted positions, substantially as described.
