COMPLETE SPECIFICATION.
Improvements in Bed Bottoms.
I, JOSEPH EDWIN TOWNSHEND, of the City of Montreal, District of Montreal,
Province of Quebec, Canada, Manufacturer, 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 reference to an improved construction in spring bed-bottoms
to render the same strong in construction, easy of being cleaned on account of their
open formation and lightness of weight, and having but a small amount of surface
between which dirt and vermin can be lodged.
The particular features which form my present invention will be hereinafter fully
set forth, described, and claimed.
In the drawings hereunto annexed similar letters of referenco indicate like parts;
and figure 1 is a plan of a bed bottom embodying my invention. Figure 2 is a
side elevation of the bed-bottom. Figure 3 is an end elevation of the bed bottom.
A are two side rails, being the length of the bed bottom desired. B are two end
rails, being in length the width of the bed bottom desired. These rails A and B form the
frame of the bed bottom, being united therefor in an ordinary manner in the positions
shewn, that is to say, with the top edes of the rails A in the same plane with the two top
surfaces of the rails B. Into the lower edge of the rails A, 1 mortise cross-rails(); three
being shewn, but a greater or less number may be used, if desired. Care ordinary knoes
at the ends of each rail C to strengthen the connections with the rails A. On the
upper surface of the frame formed by the rails A and B, 1 work a cane webbing D
similar to that used for what are called "cane-seated" chairs, but it is not necessary
to be of the same pattern as used for chairs because other patterns may also be used.
The webbing D is preferably brought round over the edges and secured in the sides
of the rails A and in the upper surfaces of the rails B. The outer upper edges of
the rails A may, if desired, be rounded off to prevent the cane webbing being cut
by a sharp square edge. On the rails Care secured a number of spiral springs E;
five being shewn on each, but a greater or less number may be used, as desired, depend-
ing on the amount of elasticity desired and the width given to the bed bottom.
These springs are preferably of what may be called the "tapered spiral" form although
other forms of spiral or other spring may be used. The springs E cause the cane
webbing to bulge upwards, as indicated by the lines 1 and 2 in figures 2, and 3.
In these figures, I have not attempted to shew the cane webbing, except where it
comes round over the sides of the rails A, because if truly illustrated the lines would
e so numerous and close that unless they were made extremely fine they would
educe the portions above the rails A in these figures to black surfaces or patches.
are connections formed of strips of hoop iron, chain, or straps, etc., etc., as desired,
ttached to and between the tops of the springs and the tops of the rails A
nd B to hold the tops of the springs E and prevent them from working out of proper
osition.
The bed-bottoms formed as above described are placed in the bedsteads in the
sual manner and receive upon them the bedding desired to be used.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;
The combination of the rails A, B, C; cane webbing D; and springs E; the
whole constructed and arranged substantially as described.
