I HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent Agents
Southampton Buildings in the County of Middlesex, 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 invention comprises improvements in that described in the Specification of
Letters Patent of the United States of America dated February 18 1879 No. 21,2400
and it consists, especially in an elastic strap for garments and other articles. The
improved strap comprises one or more springs, preferably wire coils, each of which
is covered by a fibrous jacket or covering braided upon the spring, and the ends of
which jacket or jackets, together with the ends of the spring or springs, are held in
or by a metal housing having prongs which extend through the fibrous jackets into
the springs and serve to firmly attach the ends of the springs and jackets to the metal
housings, and also to prevent the jackets or fibrous coverings from fraying or
unraveling.
In the accompanying drawing
Figures 1, 2 and 3 illustrate the manner of making or forming a metal holder or
housing for receiving and holding the ends of a number of jacketed springs of the
character specified.
Figure 4 represents the complete strap.
Figure 5 is a longitudinal section through one of the springs.
Figure 6 is a horizontal section upon the line, , of Figure 4.
Figure 7 is a view representing the invention as applied to a strap having one
jacketed spring only.
Figure 8 is a longitudinal section thereof.
Figure 9 is a horizontal section upon the line ". ". of Figure 7.

page_text: Referring to the drawings A represents springs of coiled wire, and a the fibrous
coverings or jackets thereof which are braided upon the springs.
In manufacturing the jacketed spring, the jacket is braided upon the spring in long
sections and the covered spring is then cut into the desired lengths. Each end of the
jacked spring is then covered by a metal sleeve or section of a sleeve, which has a
fastening prong which extends from the side of the sleeve through the jacket into the
spring and which is integral with the sleeve. Where several jacketed springs are used
in forming the strap as represented in Figure 4, the metal sleeves are connected with
each other, and, preferably, made from one metal plate cut or formed to the shape
represented in Figure 1, and then provided by suitable dies with half round depres-
sions b extending from the lower and upper edges thereof, and the prongs & punched
to extend inward into the sleeves.
The plate thus formed is then bent midway its width to bring the two partially
formed sections opposite each other as represented in Figure 3, and the two sections
are then united to each other by the wings which are caused to be folded or turned
about the ends of the holder or housing as represented in Figure 6. Before the two
parts of the plate are brought together, the ends of the jacketed springs to be fastened
thereto and thereby, are placed upon one part of the plate so as to be fastened thereto
upon the bringing together of its two sides, and the wire loop or other device used
for connecting the flexible strap with some other portion of the garment or article of
wear is also placed on the plate, so that when the two sections are folded together to
embrace the ends of the springs and jackets, the loop shall also be secured in place to
the plate, as represented in Figures 4 and 5.
In Figures 7 and 8 I have represented an adjusting strap having a single spring
and jacket and a metal holder or housing at each end of the character described.
I would say that the invention is not limited to an adjusting strap having jacketed
metal springs, as jacketed rubber springs, or springs of any other substance covered
with braided fibrous material, may also be used.
It will be seen that this manner of finishing ends of jacketed springs is very
desirable, in that it affords a cheap way of strongly securing the ends of the spring
and of the jacket to their metal housings, and at the same time holds the ends. of the
braided jacket in a manner that prevents them from giving at their ends and from
unraveling, and this is very essential, because the braided jackets not only serve to
cover or protect the springs, but also as stays for limiting the extent of their
movement.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
First. An elastic adjusting strap for garments and other articles consisting of one
or more springs, each of which is covered with a braided fibrous jacket, and a housing
for uniting the end or ends thereof by one or more prongs made integral therewith,
and extending into the jacket and spring, as and for the purposes described.
Second. The combination in an adjustable strap for garments and other articles, of
a plate having one or more sleeves, a prong, b¹, for each sleeve integral with the
plate, and a jacketed spring or springs, the end or ends of which are enclosed by
said sleeve, and are fastened thereto by said prong or prongs, as, and for the purposes,
described.
