page_text: I, LEWIS STEIN, of 83 Nassau Street, in the City of New York, State of New
York, United States of America, 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 :--
My invention relates especially to that class of elastic adjusting straps in which
the desired elasticity is afforded by means of spiral springs, and it consists of the
novel features of construction hereinafter described for producing a cheap, strong,
and durable connection of the spiral springs with their attaching devices.
In the acompanying drawing, Figure 1, represents a front view partly in section,
of an adjusting strap embodying my invention, the attaching devices being buckles.
Figure 2, represents a side view partiy in section, thereof. Figure 3, represents a cross
section thereof. Figure 4, represents a front view corresponding to figure 1, the
attaching devices being plain links.
Similar letters of reference indicate similar parts.
The letter A indicates the spiral springs, which may be round, oval, or of any other
selected shape, in cross section, and may or may not be covered with braid or similar
material. The free ends of each of said springs A are bent substantially at right
angles, to form coils B, projecting longitudinally from the springs and into said end
coils of the series of springs at the opposite ends thereof, are inserted wire links C,
each of which is formed with a plain straight bar or member C to receive the end
coils, so that the springs are connected to said links by means of the end coils engaging
said plain members of the links, the springs lying in a corresponding plane to eaclí
other. To permit. the introduction of either link C in said end coils B of the springs,
it is left open, and in the example shown in figs. 1 and 2, the free ends of the link
wire are arranged to form the pin tongues of a buckle, of which C is the frame, while
in the example shown in fig. 4 said ends of the link wire are simply brought together
as at 3, said link in either event being a medium for attaching the elastic strap to
the desired article, as to the back band of a vest or trousers, or to a trousers suspender.
At each end of the series of spiral springs A is a housing, D of sheet metal, which is
folded in a proper manner to embrace said member C₁ of either link, together with the

page_text: end coils thereupon as at D¹ and also to embrace the adjacent end portions of the
springs, as at D, so that these housings are connected to the links by engaging said
bar while they conceal and protect the ends of the springs.
By this construction, therefore a direct connection is effected of both the springs A
and their end-protecting housings D with the strap attaching links C, producing a
very strong and durable strap with economy of labor and material and at a compara-
tively low cost of manufacture.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In an elastic adjusting strap for garments a series of spiral springs each having its
free ends formed into coils at right angles to the springs, combined with wire links
having plain straight members inserted in said end coils at opposite ends of the springs
thereby preserving the full clasticity of the springs and sheet metal housings folded
to embrace said members of the links and the end portions of the springs for producing
a direct connection of both the springs and the housings with said links, substantially
as shown and described for the purpose set forth.
Dated this 26th day of March 1889.
