BED-FRAME AND BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 402,903, dated May '7, 1889. Application filed October 24,1888. $eria1No. 283,995. (No model.) Patented in England January 1, 1887, N0. 21.

To all whom it may concern:

Be it known that We, ISAAC OHORLTON and GEORGE LAMB Scorr, subjects of the Queen of Great Britain. and Ireland, residing at Manchester, county of Lancaster, England, have invented certain Improvements in the Construction of Bed-Frames and Bedsteads, (for which we obtained a patent in Great Britain, No. 21, dated January 1, 1887,) of which the following is a specification.

Our said invention relates chiefly to the construction of iron bed-frames and bed steads, and has for its object to dispense with the usual dovetail attachments employed to connect together the members of the bedstead at the four corners, as is well understood. Owing to the difficulty of obtaining a perfect fit, the said dovetails are seldom sufficiently secure to prevent relative movements of the parts and to keep the ends of the bedstead exactly at right angles horizontally and vertically to the side members, while owing to variations arising in molding and casting, the parts intended to come together and which should be interchangeable are not always so. In addition to these defects, the dovetail is inherently weak, and is frequently broken. According to our invention we dispense with the said dovetails and unite the bedstead at the corners by means of fittings having fiat surfaces with interlocking projections and recesses, the parts being held together by bolts or studs.

In order that our said invention may be properly understood, we will now proceed more particularly to describe the same with reference to the annexed sheet of drawings.

Figure 1 is a side view of one corner of a bedstead fitted together in our improved manner. Fig. 2 is a view of the joint from the end of the bed. Fig. 3 is a plan of the upright end. pillar of the bedstead with its corner-fitting shown detached from the fitting. belonging to the side and end member of the bedstead, which latter is shown at Fig. i. Fig. 5 is a face view of the corner-fitting shown at Fig. 3. Fig. 6 is a face View of the corner-fitting shown in plan at Fig. 4. Fig.

7 is a perspective view showing detached the bracket provided with the plug.

As clearly indicated by these figures, the corner=piece a is cast on or secured to the upright end pillar, b. The face of the cornerpiece a is flat and carries a projection, a, from which a stud, 0, extends, the said stud having a square neck at c. The stud 0 passes through a slot, d, in the bracket d, and the said bracket is also recessed, as clearly shown at Fig. 4, to receive the projection it. (Seen in Fig. 3.) \Vhen the bracket d and cornerpiece a are placed together and secured by a nut, e, on the stud c, the flat faces thus held in contact prevent the bedstead from being twisted and secure absolute perpendicularity of the end pillar, b. The square neck of the stud c, fitting the slot cl, is an additional security for preventing movement of the parts. In the example illustrated only one fittingface on the corner-piece a is required, as the bracket (1 carries not only the tubular side member, f, but also the angle-iron end member, g. To receive the side member, f, the bracket (1 is cast with a plug, which enters the tubular side member, f, and is secured thereto by a bolt, 71, or other means. The bracket 61 is formed to receive the angle-iron end member, g, to which the elastic mattress i is attached. When the mattress is strained and secured to the end members in position, nothing remains but to bolt the brackets d to the corner-pieces a, and the bedstead carrying its mattress is complete, thus forming a simply-connected and strong bedstead, which is not liable to the weaknesses and distortions of similar bedsteads connected together by dovetail fittings.

We prefer, in the manufacture of our invention, to make the improved joint of constant proportions, so that the parts may be interchangeable, not only for the same size and class of bedstead, but also for bedsteads of different types of construction.

WVhat we claim isa In iron bedsteads, the brackets cl, carrying the tubular side members, f, and angle-iron ends g, said brackets d being formed with a recess, in combination with the corner-bracknames to this specification in the presence of ets a, formed with a projection, a, which two subscribing witnesses.

fits the recess in the brackets d, and a screwed ISAAC CHORLTON. stud, c, passing through the bracket cl, and GEORGE L. SCOTT. 5 secured by a nut, e, substantially as described Witnesscs:

and shown. DAVID FULTON, In testimony whereof we have signed our J. ENTWISLE.
