CORNER-FASTENING FOR BEDSTEADS.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed February 7,1907. Serial No. 356,153.

To aZZ whom it may concern.-

Be it known that I, CHARLES VALLONE, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Oorner-Fastenings for Bedsteads, of which the following is a specification.

This invention relates more particularly to corner fastenings for metallic bedsteads, and the objects of the invention are to produce a fastening which will rigidly hold the end frames in proper position perpendicularly to the bottom frame or side rails to .which'they are connected, but which nevertheless will admit of the parts being connected and disconnected with ease and facility; also to make the construction of the fastening such that inaccuracies in the position of the fastening members in a three-piece bed, that is, a bed in Which the bottom frame is attached directly to the end frames without employing bedstead side rails, will not defeat the easy operation of the fastening; also to cheapen the cost of manufacture of the fastenings by making their construction such that they can be accurately made and finished with the least possible hand and machine work; also to provide a reversible fastening which enables the side rails to be secured to the end frames in either of two positions.

In the accompanying drawings: Figure 1 is a plan view of a reversible corner fastening embodying the invention. Fig. 2 is a side elevation thereof. Figs. 3 and 4 are perspective views of the two members of the fastening disconnected. Figs. 5 and 6 are sectional elevations of the fastening, the former showing the side rail in one position, and the latter in the reversed position. Fig. 7 is a horizontal cross-section thereof. Figs. 8 and 9 are respectively vertical and horizontal sections of a modified construction especially suitable for a three-piece bed.

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

The corner fastening comprises two members, one attached to the end frame and the other to the bedstead side rail or bottom frame. One member has a horizontally-proj ecting headed stud and the other member is slotted vertically to receive the headed stud. In the reversible fastening shown in Figs. 17 of the drawings, the fastening member A,

which is attached to the bedstead side rail (1., carries the headed stud, and the other member B, which is attached to the end frame 6, is slotted to receive the stud. The stud could, however, be provided on the end frame member and the slot in the side rail or bottom member, as shown in Figs. 8 and 9. The form of the bodies of the members A and B is dependent upon the shape of the end frame and side rail or bottom frame to which they are to be attached and the manner of securing them in place. In the construction shown, in which the member Ais secured to an angle-bar side rail, it has horizontal and vertical webs a a respectively, which are riveted to the corresponding flanges of the side rail.

C represents the headed stud which proj ects fi'om the vertical bearing wall or end of. the member A. The stud has a transversely narrow shank and a large head, the inner face 0 of which at opposite sides of the shank is vertical and flat or plane.- The bearing wall from Which the stud projects, see Figs. 2 and 3, has four inclined surfaces, d d d d, which face toward the head of the stud, the alternate surfaces (1 (1 being preferably inclined in one direction and the other two surfaces d and d being inclined in the same direction with respect to each other but in the opposite direction to said first two surfaces (1 and (P. The bearing wall thus has two salient bearing parts separated by a depression. The vertical end or wall of the stud member also preferably has holes e through it at opposite sides of the stud shank to facilitate finishing the inner face of the stud, as.

will be explained later.

The slotted fastening member B, in the construction shown in Fi s. 17, has a tubular attaching portion which surrounds and is secured on the side post of the end frame in theusual or any suitable manner, and a projecting body or part f which is vertically slotted to receive the head and shank of the stud C and has a vertical bearing wall or end to co-operate with the bearing wall of the stud member. The bearing end or wall has fiat upright inside faces f at opposite sides of the slot, for the flat faces of the head of the stud to bear against, and the upper end of this bearing wall is preferably beveled or reduced to facilitate the engagement of the stud in the slot. The vertical end or wall also has outside upper and lower surfaces 9 9 against which the bearing surfaces of the stud member bear and which incline both in the same direction and are separated by an intervening depression or hollow 9 see Figs. 2 and 4.

To couple the two members of the fastening one or both of them is or are tilted slightly from the vertical and the stud engaged in the slot and the one member then shoved down on the other until it finds a firm bearing. In the position of the stud member shown in Figs. 2, 3 and 5, its inclined bearing surfaces (1 and (i will engage theginclined bearing surfaces of the slotted member and when it is shoved downwardly they will force it laterally until arrested by the wedging of the slotted wall between the head of the stud and the bearing wall of the stud member. If the stud member were inverted as shown in Fig. 6, the members would be wedged together in a similar manner, but by the action of the other two bearing surfaces (1 and d of the stud member on the inclined bearing surfaces of the slotted member. The members have a three-point bearing upon each other with the two bearing points between the inclined faces above and below the third bearing point formed by the head of the stud on the opposing surface. This relation of the inclined bearing surfaces prevents any possibility of one member rocking on the other about the stud as a center, either longitudinally or transversely of the fastening members, and thus a much firmer and more rigid connection of the members is secured than in constructions having an oppositely ta-' pered stud head forming the center bearing and fiat faces for the other hearing or bearings. In this construction also the inclined or wedging surfaces are exposed or on the outsides of the members where they can be readily finished or trued up by the blow of a die in a stamping press if they are left rough or imperfect in casting. On the other hand, the internal bearing faces of the slotted member are straight and can be easily smoothed and trued up by a tool inserted in the chamber of said member, which would be a more difficult operation if the chamber were tapered. If the flat bearing faces of the stud head are left rough or uneven in casting, they can be finished by a blow in a press by employing a die having parts adapted to extend through the holes (2 in the vertical wall of the stud member and bear against the flat face of the head of the stud. These are important considerations in the manufacture of the fastenings enabling them to be made perfectly, so that they will operate nicely, at small expense. The slot is made wide enough for the stud to have some lateral play therein and this enables the fastenings to properly engage although there may the members on the end and bottom frames in a three-piece bedstead.

Figs. 8 and 9 show a fastening especially adapted for three-piece cribs or bedsteads, in which the stud member A is attached to the end frame and the slotted member B to the bottom frame or side rails. In this fastening the shape of the bodies of the members differs from the corresponding parts in the fastening first described but the same relation of the interlocking or bearing parts is retained. In bothfastenings, one member has a headed stud and opposite inclined bearing surfaces or projections above and below its center, and the other member has exterior inclined bearing surfaces to co-operate with the bearing surfaces of the first member, and a slot with straight upright faces at opposite sides thereof on which the head of the stud bears.

I claim as my invention:
