1, 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 :-
This Invention particularly relates to Improvements in machines for constructing
corrugated metallic Weather-Strips for doors, windows &c. having its several parts
so constructed and arranged that the thin metallic strip is first formed into shape
having longitudinal corrugations or ribs the entire length thereof; and having the
two edges underturned, one of the edges having a large under lap or curve than the
other to receive the corded lapped edges of the rounded hollow rubber cushion, and
rigidly hold the same with-in its coiled recess, while the opposite or smaller lapped
edge of the metallic binding strip is closely folded under to form a rounded smooth
bearing edge at the base of the hollow cushion when nailed upon the sill of the
window or jam of the door.
In order that the public may fully understand the nature of my Improvement,
and those who are skilled in the mechanic arts may be enabled to construct and use
the same, I will describe it as follows to wit:-
Referring to the accompanying Drawings, which form a part of this application
in which

plate. o. o are guide plates a. is the entering roll, b. is tho male and female first
rotary former or feeding rolls, c. is the upper forming roll, or male die, d. is the
horizontal top plate of the inside former more clearly shown at figures 7 and 9.
e. e is the metal guide to direct the rubber strip into the beveled forming rolls n. n'
(from the outside) f. represents the upper or male clamping die, g. and n. are arbors,
i. is the crank, j. j. are lugs to secure the machine to the table or bench; k. k. are the
caps to hold the adjusting screws I; the set screws are shown at m³.

and rotary former b. guide plate o.

Figs. 4, and 5, are end views of fig. 3, showing the face or plan of the guide
plate o. o¹.

regulate the pressure of the forming and clasping rolls; p. p¹ are driving gears,
g. is the connecting gear; r. are auxiliary gearing.

cap-plate d. fig. 1.
Fig. 8, is the reverse or under side of plate d.
Fig. 9, is the plan of the horizontal forming rolls m. m' operating under plate d.
(which is removed to more clearly show the rotary formers m. m³.
Fig. 10, is a vertical- view of the beveled forming rolls n. n¹ operating in com-
bination with vertical rotary former t. See fig. 1.
Fig. 11, shows the rubber guiding device e. e¹ to be attached to fig. 10. at 2. 2¹.
Figs. 12 and 13, are male and female rotary formers or dies.
Figs. 14 and 15, are clasping or finishing rotary dies ready to be placed on the
arbors for use.
I will next proceed to describe the operation of making a metallic Weather-Strip
ready for use.
Take a narrow strip of zinc or copper of the required width and introduce the end
thereof through the guide plate o. of the machine fig. 1, over the entering roll a.
between the forming feed rolls b. which conducts it the strip through the guide
plate o from whence it passes into the forming rotary dies, the top or male die of
which is shown at c. fig. 1, then the rotary action of the working parts of the
machine causes the metal strip to enter and pass through the horizontal formers
under plate d. from thence the strip passes through the combined device n. n¹ and t.
more clearly shown at fig. 10. I would here state that the rubber strip is now
entered from the (out-side) into the guide at e. from whence it the rubber is passed
into the larger curved recess of the metallic strip or binder at n. n. from which
point the rubber becomes securely clasped within the larger coil of the metallic
binding strip, and when thus united is carried through the clasping or forming rolls,
or dies, the top one of which is shown at f. fig. 1, which finishes the operation.
After having set-forth the several parts of my Invention, I would here state that
its novelty consists in the construction of a machine that will automatically form
into shape a beaded or corrugated rigid thin metal strip, that will grasp and hold
within its coiled recess the corded lapped edges of a rounded hollow flexiblo
cushion, and complete the same ready for use by one continuous rotary movement of
the several parts thereof.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent 1 declare that what I claim is :—
First: A machine that will antomatically produce by a single operation a corru-
gated metallic binding strip, and firmly secure the same to the lapped corded edges
of a flexible hollow rubber cushion, when drawn within the coiled recess of said metallic
binding strip; so that the opposite or free edge of said metallic strip is formed into

page_text: a smooth rounded edge by being under-lapped to firmly press down upon the base
of the thin hollow cushion when the same is nailed to the sill of window, or jams of
the door, substantially as above described.
Second What is claimed in this application as an Improvement in machines for
making corrugated metallic Weather-Strips, is the horizontal forming device shown
at m. m² and v. (under plate d.) also the beveled rollers n. n' and t. operating with
the (metallic) rubber guide e. e¹ constructed as shown and described and operating
in combination with a. b. c. o. o¹ and f. The whole constructed, arranged and
operating, for the specific purpose set forth.
