BEDSTEAO.

SPECIFICATION forming part of Letters Patent No. 567,731, dated September 15, 1896. Application filed January 16, 1896. Serial No. 575,707. (No model.)

To all whom it may concern;

Be it known that I, EDWARD J. BARCALO, a citizen of the United States, residing at Bu ffalo, in the county of Erie and State of New York, have invented a new and useful linproveinent in Bedsteads, of which the following is a specification.

This invention relates inore particularly to inetallic bedsteads in which the posts or pillars are secured in couplings which connect the side and end rails of the bedstead, and in which the rods or members that connect each pair of posts are united by separable couplings. A bedstead of this character is shown in Letters Patent of thel United States, No. 536,368, granted to me March 26, 1895.

One of the objects of' niy present invention is to so construct the corner-couplings of the bedstead that end and sideA rails having the forni of angle'iron can be reliably clamped to the couplings, ii' desired.

`The invention has the further objects to secure the posts in such couplings by simple and inexpensive means, to improve the construction of the feet of the posts in which the casters are swiveled and the bearings of the caster-spindles, and to simplify the couplings which connect the rods ofthe end frames of the bedstead.

In the accompanying drawings, Figure 1 is a vertical cross-section of the bedstead. Fig. 2 is a sectional elevation of one of the rait couplings and the adjacent rails on an enlarged scale. Fig. 3 is a horizontal section thereof in line 3 3, Fig. 2. Fig. t is a siinilar section in line a 4, Fig. i?. Fig. 5 is a side elevation of said coupling, showing1 the end rail in cross-section. Fig. 6 is a vertical sec tion of the sleeve of the rail-coupling at right angles to Fig. 2. Fig. 7 isa sectional. elevation of' the foot of one of the posts. Fig. 8 is a horizontal section thereof in line 8 S, Fig. 7. Fig. 9 is an enlarged vertical section of the caster-spindle and its bearingsleeve. Fig. 10 is an end view of one of the rod-couplings, showing the key whereby the saine is clamped to the rod. Fig. 11 isa similar view showing the locking-pin of the rod turned into register with the groove of the coupling. Fig. 12 is a vertical section in line 12 l2, Fig. 1l, showing the frame-rod by dotted lines. Fig. 13 is an enlarged fragmentary crosssec tion of the bedstead, showing the side rail reversed.

Like letters of reference refer to like parts in the several figures.

A represents the side rails of the bedstead which connect the end frames, and which are preferably constructed of angle-iron or flatsided tubing. Each of the end fraines is preferably composed of' the two posts or pillars B, the end rail or rod B connecting the saine, the transverse upper rod b, intermediate transverse rods b', and upright rods b2, which connect said intermediate rods.- The end rail B' is preferably constructed of round tubing'.

The end and side rails are detaehably connected by corner fastenings or couplings, each of which consists of an upright sleeve O, e1nbracing the adjacent post, and provided with two horizontal sockets O O2, projecting from said sleeve and arranged at right angles to each other. These sockets receive the end portions of the side and end rails, respectively, the transverse socket O of the coupling being roundv in cross-section to iit the correspondingly shaped end rail of the bedstead and the longitudinal socket O2 rectangular in cross-section to iit the fiat-sided side rail. The sockets of each coupling are provided with setscrews d, or other suitable clamping devices, for securing the end and side rails in the sockets, these set-screws being tightened and loosened by a suitable wrench D. By providing the couplings with rectangular sockets, side rails of angle-iron `can be firmly clamped in the same, if desired,

in which case the clamping-screws of the sockets impinge against the horizontal flange of the angle-iron. The angle-iron rails niay be arranged with the horizontal flange at the bottom of the vertical iiange, as shown in Figs. 1, 2, and 5, in whichV case said horizontal flanges forni ledges for the mattress; or the angle-iron rails may be reversed to locate the horizontal fiange at the top of the vertical fiange, as shown in Fig. 13, in which case the clamping-screws are lnade of sufficient length to bear against the under side of the horizontal flanges. Y

The sleeve of' each coupling is secured to the adjacent post by a locking-pin e, arranged on the post andVv engaging' in an L-shaped groove e', formed in the inner wall of the sleeve at or near one end thereof, and a key or pin f, which is driven into a longitudinal notch f', formed in the opposite end of the IOO les

sleeve, so as to clamp the sleeveto the post, as shown in Fig. 2. In applying the coupling to the post, after passing the sleeve over the post the pin of the latter is interlocked with the L-shaped groove of the sleeve and the key f is then driven into place.

G represents the feet or enlargements of the posts in which the swiveling casters 7L are journaled. Each of these feet is hollow or socketed to receive the lower end of the post and is provided at its upper end with a contracted neck g, which snugly embraces the post. In order to afford a longer bearing-surface for the post within the hollow foot, the latter is provided with an internal radial rib g, against which the adjacent side of the post rests, as shown in Figs. 7 and 8. The foot is secured to the post by driving` the same upon the post.

h/ is the upright cylindrical shank or spindle of the caster, which is journaled in an upright sleeve or bearing-tube l, secured at its lower end in an opening formed in the bottom of the foot and extending upwardly into the latter, as shown in Fig. 7. The caster is removably retained in its bearing-sleeve by a catch j, secured to its projecting upper end. This catch preferably consists of an upright spring, which is secured to the spindle at its lower end and provided with a shoulder or bulgej, adapted to bear against the upper end of the sleeve l, as shown in Fig. 9. Upon inserting the caster-spindle into the bearingsleeve, the springj fiattens out against the side of the spindle, the spindle being fitted in its bearing-sleeve with sufficientlooseness for this purpose, and as soon as the spindle projects beyond the upper end of the sleeve the spring resumes its normal form as shown in Fig. 9, thereby yieldingly retaining the spindle in the sleeve.

K represents the couplings whereby the upright and transverse rods b b2 of the end frames are connected together. Each of these couplings consists of a hollow body preferably of circular form, provided in opposite portions of its cylindrical wall with openings k for the passage of one of the transverse rods b' and with a radial socket or projecting collar 7c', which receives the end of one of the upright rods b2. The coupling is held against lateral displacement on the transverse rod by a locking-pin l, secured to said rod and interlocking with the vertical portion of an L- shaped groove k2, formed in the inner side of one of the fiat side Walls of the coupling, as shown in Fig. 12. The horizontal portion of this groove extends through the cylindrical wall of the casing, forming a notch in the edge of the adjacent opening 7c, as shown in Figs. lO and l1. Into this notch is driven a key or pin m, 'as shown in Fig. l0 and by dotted lines in Fig. l2, whereby the coupling is clamped upon the transverse rod and the pin of the latter is prevented from leaving the vertical portion of the L-shaped groove.

In securing the coupling to the transverse rod, the latter is turned so as to bring its locking-pin into register with the horizontal portion of the L-shaped groove of the coupling, as shown in Fig. l1, and the coupling is then shifted laterally to cause the pin to enter said groove, whereupon the rod is turned in the proper direction to cause its pin to interlock with the vertical portion of the groove. The keyis then driven into the horizontal portion oi the groove.

In assembling .the rods and couplings of the end frames, the couplings are first secured to the intermediate transverse rods, and the upright rods are then inserted in the sockets of opposing couplings.

lt will be noticed that the slot in the coupling and the pin on the post serve to position the coupling and rail in relation to the post and the key locks the coupling rigidly to the post after the position thereof has been determined.

I claim as my inventionl. The combination with the post, having a locking-pin and the adjacent side and end rails of a coupling having a vertical opening to receive said post, the lower end of the coupling having a bayonet-slot therein adapted to be engaged by said locking-pin for positioning said coupling on said post, and the key for locking said coupling rigidly to the post after the position thereof has been determined.

2. The combination with a post of a bedstead, of a foot or enlargement secured to said post and having a socket which receives the lower end of the post and an internal radial rib against which the adjacent side ofthe post bears, substantially as set forth.

The combination with an upright member of the bedstead-frame and a transverse member thereof having a locking-pin, of a coupling consisting of a hollow body provided in opposite sides with openings for the passage of said transverse member, a socket for the reception of the upright member and an internal L.shaped groove adapted to interlock with the locking-pin of said transverse member, substantially as set forth.

et. The combination with an upright member of the bedstead-irame and a transverse member thereof having a locking-pin, of a coupling consisting of a hollow body provided in opposite sides with openings for the passage of said transverse member, a socket for the reception of the upright member, an internal L-shaped groove adapted to interlock with the locking-pin of said transverse member, and a key whereby the coupling is clamped upon said transverse member, substantially as set forth.

Witness my hand this 13th. day of January, 1896.
