or double helical springs arranged upon rods at the sides and ends of the
frame, or either the sides or ends, in such a manner that their bales or
ends-point upward and inward; they are connected together by means
of straps, cords, webbing, wires, or their equivalents interlaced; or they
may be connected by wooden slats or spring bars secured to the said
bales by slots, grooves, hooks, or otherwise, the whole forming an elastic
and easy seat or bed bottom, economical of construction, durable in
wear, and which affords no facilitics for harboring insects. The ends of
the spiral portions of the springs are secured to the frame by being let

"IMPROVEMENTS
IN SPRING SEATS AND BED BOTTOMS," a communication to me from abroad
by John Lorenzo Whipple, of Detroit, Michigan, United States of
America, upon the condition (amongst others) that I, the said William
Robert Lake, my executors or administrators, by an instrument in writing

page_text: under my, or Encir, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said 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 relates to an improved construction of carriage, chair,
and other spring scats and bed bottoms, and consists in the use of single
or double helical springs arranged upon rods at the sides and ends of the
frame, or on either the sides or ends, in such a manner that their bales
or onds point upward and inward, where they are connected together by
means of straps, cords, webbing, wires, or their equivalents interlaced,
or by wooden slats or spring bars secured to the said bales by slots,
grooves, hooks, or otherwise, the whole forming an elastic and easy seat
or bed bottom, economical of construction, durable in wear, and which
affords no facilities for harboring insects.
In adapting my Invention to the frame of a carriage seat the bales of
double helical springs are connected by means of the interlaced straps
or webbing. Upon the said frame are secured rods by means of eye
bolts, and upon these rods are placed the double helical springs, whose
bales are connected by the interlaced straps or webbing. The ends of
the spiral portions of these springs are secured to the frame by being let
or driven into the same. Where slats or spring bars are employed the
webbing or other article used to connect the bales is dispensed with.
Having thus described the said Invention as communicated to mo
by my foreign correspondent, I claim, the springs with upwardly and
inwardly pointing bales in spring seats or bed bottoms.
Also the connecting of such bales by means of straps, cords, webbing,
and wires, or their equivalents, either continuous or otherwise, or by
sluts or spring bars, for the purposo specified.
Also the rods upon which the said springs are secured in connection

page_text: with
any
suitable frame, and the eye bolts by means of which the springs
are secured to the said frame.
In witness whereof, I, the said William Robert Lake, have hereunto
set my hand and seal, this Eleventh day of August, in the year of
our Lord One thousand eight hundred and seventy.
Witness,
W. J. LOWE.
WILLIAM ROBERT LAKE. (L.S.)
