COMPLETE SPECIFICATION.
Improvements in Metal Bedsteads.
I, THOMAS COLLERAN, residing at 123, McCaul Street, in the City of Toronto,
in the County of York, in the Province of Ontario, Canada, Blacksmith, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The object of this invention is to construct a coupling bracket, by means of
which the side and end rails can be rigidly united and fastened to the upright
posts; and the invention consists essentially of the device hereinafter more fully
set forth and more particularly pointed out in the claims.
In the drawings, Fig. 1, is a perspective view of a portion of a bed shewing a
coupling bracket with a section of an upright post and the end and side rails.
Fig. 2, is a perspective view of the female member of the coupling bracket.
Fig. 3, is a perspective view of the male member of the coupling bracket. Fig. 4,
is a perspective view of a section of the end rail looking at it from one end. Fig. 5,
is a perspective view of a section of a side rail. Fig. 6, is a perspective view of
a section of the clamping bar. Like letters of reference refer to like parts
throughout the specification and drawings.
A represents an upright post, and B represents the female member of the
coupling bracket, rigidly connected to the upright post A. The female member B
consists preferably of a forging of any suitable shape and size. Formed in the
forging is a frustro-conical slot b, adapted to receive a correspondingly shaped
plug C, integrally formed with the male member 1 of the coupling bracket. The
male member D consists of a vertical plate E and a horizontal plate F, extending
from the top of one side of the plate E. Formed integrally with the opposite side
of the plate E is an inverted frustro-conical plug C, which is adapted to enter
the inverted frustro-conical slot in the female member B of the coupling
bracket, and rigidly fasten the female member to the male member D.
G. re-
presents a horizontal stud extending outwardly from the plate E, and on the
same side of it as the horizontal plate F. That face f of the horizontal plate F
contiguous to the stud G is concaved, the concavity of which is concentric with
the perimeter of the stud G. The stud G is remote from the concaved face f
of the horizontal plate F, a distance equal to the thickness of the tubular side
rail H. Extending upwardly from the top of that side of the vertical plate E,
contiguous to the plug C is a flange c, the height of which is approximately equal
to the thickness of the end rail I. Formed in the top of the vertical plate E,
between the flange c and the opposite edge of the plate, is a channel J to receive
the depending flange K of the end rail I. The entry of the flange K into the
channel J prevents the lateral displacement of the end rail. Mounted on the top
of the end rail I is a clamping bar L, the purpose of which is to bind the bed
bottom M to. the end rails. Passing through the end of the clamping bar L, and
rail I, horizontal plate F side rail H and stud G, is a bolt N, one end of which is
provided with a head O, and the opposite end of which is fitted with a nut P.
