Improvements in and relating to the Jointing Seams of Waterproof
Garments, and Appliances connected therewith.
I, JOHN BURNETT, of 110 John Street, Glasgow, Lanarkshire, Waterproof
Manufacturer, do hereby declare the nature of my invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement in writing reference being had to the accompanying
drawings, that is to say :-
This invention has reference to improvements in and relating to waterproof
garments, and comprises a new or improved method of waterproofing and rendering
more pliable the jointing seams of the cloth, and dispensing with the overlay or
waterproof cloth taping heretofore used where double thickness, or tape and sewn
seams are formed on these garments and enable said seams to be made by
inexperienced workpeople.
And in order that my said invention, and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended two explanatory sheets of drawings, in which the same reference letters
are used to indicate corresponding parts in all the figures where shown.
Figures 1 and 2 on Sheet 1 are edge and plan views respectively of part of a
waterproof garment showing a double thickness sewn seam as formed and cemented
in accordance with my improvements.
Figures 3 and 4, are a sectional elevation and plan view respectively and
Figure 5 an edge elevation at right angles to Figure 3 of an improved hand
operated solution retaining and spreading device for carrying my improvements
into practice. While
Figure 6 is a sectional elevation of another arrangement of solution retaining,
and spreading device suitable for coating and rendering waterproof the parallel
lines of thread stitching on the garment seams.
Figures 7 and 8 are a sectional elevation and plan view respectively of part of
a bench over which the garment seam is placed when spreading the waterproof
solution on it. While
Figures 9, 10 and 11 are an end view and side elevation partly in section and a
plan view respectively of a roller apparatus through which the seam is travelled to
get pressed and bound together.
Referring to Figures 1 and 2 of these drawings.-The improvements essentially
consist in dispensing with the usual overlay or waterproof cloth taping and in
making the double thickness sewn scams a of garments A waterproof by coating
said seams a on the inside surface of the garment A with a waterproof solution
consisting of indiarubber, dissolved in petroleum, naphtha, or other solvent, in
admixture with coloring basic substances such as zinc oxide or carbon or other like
substances which preferably makes the coating resemble the color of the proofing
used on the inside surface of the cloth, and this coating is then preferably dried or
coated over with a thin layer of the colored material used, in a dry powdered state.
This seam may also be proofed by the application of seini cured adhesive tissue
cut by a guillotine knife to the width necessary to cover the stitching. This tissue
may consist of very fine demi "Indiana zephyr" covered on one side with rubber
of any color necessary to resemble the proofing of the garment to which it is to be
applied. The tissue on the other side may consist of a fine coat of prepared
india-rubber solution of an adhesive nature which being left in a semi cured state
immediately adheres to the seam. The solution is applied over the jointing surface
of these seams a by hand operated devices, and one arrangement of mechanism for
effecting this as shown in Figures 3 to 5 consists in forming a thin rectangular box
.

page_text: casing B open at top B and bottom B³, and in having a portable sliding shutter
bottom b, preferably of a curved segmental shape as shown extending from the
top B of the one end of the casing B between the side plates B3, B4, to the
bottom B' near the other end of casing, where a transverse vertical adjustable
plate would be fitted to slide on edge in grooves formed in the side plates B, B,
and be operated by a hand screw carried on a bracket support 68, or other
equivalent actuating device. One of the sides B4 of casing B would preferably be
formed at top B₁ of a bulged out semi-hopper shape B to receive and hold the
waterproof solution, which would preferably, be of a viscous consistency. The
adjusting of the sliding or movable bottom b would regulate the opening and
quantity of solution to be passed and breadth of seam to be spread over, while the
adjusting or raising or lowering of the vertical transverse sliding plate b¹ by the
screw 6s would regulate the thickness of the waterproof coating to be placed on
the jointing seam a of the garment A, as the device is drawn by hand over it.
Under another arrangement the waterproof coating would only be applied to
cover and render waterproof the parallel lines of thread stitching shown dotted
at a' a' in Figure 2 on these scams a. This would be effected as shown in Figure 6
by making the vessel which contains the solution in the form of a vertical cylinder C,
having a movable piston or plunger C₁ at its upper end prossed down by the tension
or pressure of indiarubber spring bands C2, C3, attached to clips c on the sides of
cylinder C and to similar clips on a crosshead e' attached to upper end of piston
rod C³, and sliding in slots C in the cylinder C but it might be by the tension of
spiral or other springs or spring rods. A valve or opening d is fitted at the lower
or bottom end of cylinder C leading into a delivery shoot or tube d. This valved
would be opened when the device is to be used, by pressing the finger against a
spring shutter or spring recoil spindle d working through a stuffing box at d³, which
would admit the solution to the lower delivery tube and this would be drawn by
hand along the line or lines of stitching a, a, Figure 2, so as to spread the
solution over same, and on the withdrawal of the finger the recoil of the spring
shutter would close the valve d over the opening to the shoot d', and shut off the
supply of coating solution.
In spreading the solution over the garment seam with the devices shown in
Figures 3 to 5 and 6, the seam would be placed over the frame block D shown
in Figures 7 and 8 and the spreading devices drawn over it. This frame block D
is hinged at D' to the bench D', so that it can be folded over and down to the
dotted position shown in these figures. After the solution has been applied to the
seam, the latter is passed through between the rollers E E, in the apparatus shown
in Figures to 11. This apparatus consists of a hinged over hung frame F, in
which is mounted a spindle carrying a roller E' in a hollow head F³, at its one
end and having a pulley F³ at its other end driven by a band from any prime
moving shaft or it might be driven by hand. The roller E drives by stiff friction
the roller E which is mounted loosely by end journals in the cheeks of the hollow
head frame F. The lower roller E is mounted loosely by end journals in a movable
or adjustable hollow frame G carried on lower pins or spindles G' and capable of
moving adjustably on same by the recoil springs G. The frame G is covered in
by a cap or cover g and the ends of the pins Gare passed through an under-hung
bracket or sole g sunk below the basement Z. The garment seam after being
solutionised is thus passed through between rollers E E', to get pressed and finished,
and the lower roller E is rendered adjustable by having its frame G carried on the
spring compensating pins G¹, G³.
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.-
First. The herein described method of waterproof coating, finishing and rendering
more pliable the double thickness jointing seams of waterproof garments, and
dispensing with the waterproof cloth taning substantially as set forth

page_text: Second. A device for holding and adjustably spreading layers of waterproof
solution on garment seams, substantially as described in reference to and shown in
Figures 3 to 5 of the accompanying drawings.
Third. A device for holding and spreading waterproof solution on lines of thread
stitching on garment seams, substantially as described in reference to and shown in
Figure 6 of the accompanying drawings.
Fourth. A device for rolling, pressing and finishing the solutionized jointing
seams of waterproof garments, substantially as described in reference to and shown
in Figures 9 to 11 of the accompanying drawings.
Fifth. A device consisting of a hinged turn-over frame block, for laying the
garment seam on while spreading the waterproof solution, substantially as herein
described in reference to and shown in Figures 7 and 8 of the accompanying
drawings.
