Improvements in Mattress Frames.
We, ALPHONSO EUGENE KENNEY and WINFIELD HERRISON TABER, both
of No. 98 Merrimac Street, Boston, Massachusetts, United States of America,
Merchants, 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 :-
This invention has for its object to construct a metallic mattress frame especially
designed for woven wire or kindred mattresses, and consists in the combination of
cylindrical tubular side rails, and cylindrical tubular end rails, and grooved blocks
interposed between said rails at the corners, and bolts or equivalent fastenings
for securing said side and end rails together.
Also in the combination of the side rails slotted at the ends, and end rails and
grooved blocks interposed between said rails at the corners, means for securing one
of said end rails to the side rails, and bolts for securing the other end rail to the
side rails, movable in the slots thereof, nuts on said bolts, and eye-bolts, the eyes of
which engage the shanks of the securing bolts, and nuts therefor for the purposes
of adjustment.
Also in the combination of the side rails and end rails, one of said end rails being
slotted from end to end, to receive the end of the mattress, means for contracting
said slotted end rail to thereby firmly clamp and hold the end of the mattress.
Also in the combination of the side rails and end rails, one of said end rails being
slotted from end to end, to receive the end of the mattress, and means for contract-
ing said end rail to thereby firmly clamp and hold the end of the mattress, and
straps which embrace said end rail the ends of which are connected with the side
rails, whereby said end rail may be rotated by a spanner or other suitable
implement when said straps are loosened for the purpose of adjustment.
In the accompanying drawing
Figure 1 shows in plan view, a mattress frame embodying this invention,
supporting a woven wire mattress.
Figure 2 is an enlarged sectional detail of one of the corners taken on the dotted
line Figure 1.
Figure 3 is an enlarged sectional detail of another corner taken on the dotted
line
yy Figure 1.
Figure 4 is a cross section of one of the end rails with the mattress removed.
Figure 5 is a similar cross section of one of the end rails with the mattress
engaged and held by it and
Figure 6 is a perspective view of one of the corner blocks, which are placed
between the side and end rails.
Similar letters of reference indicate corresponding parts in the several figures of
the drawing.
The side rails a, b, are made alike consisting of cylindrical tubular metallic rods
or bars, and the end rails c, d, are also made alike consisting of cylindrical tubular
metallic rods or bars, slitted as at c', see Figure 4, from end to end.
The side rails and end rails are arranged at right angles with relation to each
other to form a quadrangular frame, and to prevent said rails twisting or turning
one with relation to another when secured together, blocks e see Figure 6, are
interposed between the side and end rails at the corners where said rails cross one
another, said blocks having each two grooves formed in it, one upon its upper and
the other upon its under side, and arranged at right angles with relation to each
other, and shaped to receive the side and end rails.

page_text: At one corner of the mattress frame, a bolt c³ passes down through holes made in
the end rail c, also through a hole made in the interposed block e and through slots a¹
made in the side rail a, said bolt being supplied with a nut c³.
This bolt csecures one end of the end rail c to one end of the side rail a.
The other end of the end rail c is secured to the side rail b in the same manner.
The open ends of the side rails a, b, adjacent the end rail c are closed by caps c*,
having externally projecting squared ends c adapted to receive a wrench,.and
having screw threaded holes through them which receive the shanks of the eye-
bolts, the eyes of which embrace or are connected with the shanks of the
bolts c³.
Said closing caps therefore serve as nuts and by turning them in one or the other
direction, the bolts will be correspondingly moved in the slots in the side rails,
thereby adjusting the end rail c with relation to the end rail d.
Thin metallic plates fare or may be placed upon each side of the side rails to
cover the slots a¹ therein.
At the opposite end of the mattress frame the end rail d is embraced at points
near the ends by straps d', the ends of which pass down through the side rails, a, b,
see Figure 3, and are supplied with nuts d, thereby firmly securing the said end
rail with the block e interposed between it and the side rails.
The strap d', it will be seen, may be loosened and thereby permit the end rail d
to be turned by means of a spanner or wrench, to tighten the mattress if desired,
after which said strap may be tightened, or in lieu of adjusting the mattress at this
end of the frame in this manner, it may be adjusted similarly to the opposite end of
the frame.
When a spanner is used for turning the end rail d it may be made to engage the
head of a short bolt 2, as represented by dotted lines Figure 5.
In securing the mattress to the end rails c, d, the ends h of the mattress are
inserted in the slots c¹ and short bolts 2, pass through said end rails supplied with
nuts 3, so that by turning said nuts the end rails are contracted thereby firmly
clamping and holding the ends of the mattress.
The short bolts 2, may and preferably will pass through the meshes of the
mattress as represented in Figure 5.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The mattress frame herein described consisting of the combination of the
cylindrical tubular side rails a, b, and the cylindrical tubular end rails c, d, and
interposed grooved blocks e made as shown, and bolts or equivalent fastenings
securing said side and end rails together.
2. The mattress frame herein described consisting of the combination of the side
rails a, b, slotted at the ends as at a', the end rails c, d, and interposed grooved
blocks e as shown, means for securing the end rail d to the side rails, and the bolts c
for securing the end rail c to the side rails, movable in the slots a¹ thereof, nuts co
and eye-bolts c' engaging the bolts c³, and nuts therefor, substantially as described.
3. In a mattress frame, the combination of the side rails a, b, and end rails c, d,
one of which is slotted from end to end to receive the end of the mattress, and
means for contracting said slotted end rail to thereby firmly clamp and hold the end
of the mattress.
4. In a mattress frame, the combination of the side rails a, b, and end rails C, d,
one of which is slotted from end to end to receive the end of the mattress, and
means for contracting said slotted end rail to thereby firmly clamp and hold the end
of the mattress, and straps d' embracing said end rail, the ends of which are
connected with the side rails, and means for turning said end rail when the straps
are loosened.
5. The mattress frame herein described consisting of the combination of the

page_text: tubular side rails a, b, and tubular end rails c, d, and means for securing them
together at the corners.
6. In a mattress frame the combination of the side rails a, b, and end rails c, d,
oe of which is slotted from end to end to receive the end of the mattress.
