Year: 1853

page_text: LETTERS PATENT to James Chadnor White, of Liverpool Street,
in the City of London, Harness Maker, for the Invention of
"IMPROVEMENTS IN FASTENINGS FOR HARNESS, AND WHICH ARE ALSO
Sealed the 19th August 1853, and dated the 19th February 1853.
PROVISIONAL SPECIFICATION left by the said James Chadnor.
White at the Office of the Commissioners of Patents, with his
Petition, on the 19th February 1853.
I, JAMES CHADNOR WHITE, of Liverpool Street, in the City of
London, Harness Maker, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN FASTENINGS POR HARNESS, AND WHICH ARE
ALSO APPLICABLE TO OTHER LIKE PURPOSES," to be as follows:-
Firstly, in an improved tug slide, for the better securing of
traces; secondly, in the application of a galvanized iron tube to
traces in connection with the said slide; and, thirdly, in a variation
of the principle of the slide, by means of which a buckle or clasp
of a peculiar construction is produced.
For the better understanding of my said Invention, I shall now
proceed to a particular description of the same, with reference to

page_text: the Drawings hereunto annexed, in which the same figures & letters
denote corresponding parts in each Drawing.
Fig. 1, a view of the top surface of an improved tug slide. A, B
is a metal frame, having an oblong square opening in its centre,
from C to D, and a groove within on each side, extending from
A to A¹, and from B to B'. In this groove slides the oblong square
metal piece E, F, with a feather edge at A", and another at B
corresponding with the grooves A, A', and B, B. The slide E, F,
carries a spring G, H, the latter part H being concealed under the
slide. This spring must be placed at the end E of the slide piece.
At I, is a square metal stud, so arranged that the face of it shall be
level with the main upper surface of the frame A, and the slide E,
and also exactly fill the corresponding aperture J, in the frame,
when the slide is pushed home, that is, when the end E of the
slide is brought in a line with A, B', thus forming a stop, and
venting its return until pressed down for the purpose of releasing
and pushing back the slide piece.
pre-
Fig. 2, is a longitudinal section through the centre of Fig. 1; A,
the external frame; C, the centre aperture; B¹, the groove; E, F,
the slide piece; G, H, the spring; I, the square stud, capable of
filling the aperture J, when pressed therein by the spring; K, K,
four pins or shanks, cast on one side underneath, there being also
an equal number on the opposite underneath side. These are passed
through the leather cover of the galvanized iron tube, and rivetted
over a brass or other metal plate placed inside the cover.
Fig. 3, is a plan of the metal plate, with K, K, eight holes
corresponding to the eight pins shewn in Fig. 2, and an aperture at
M, for a screw; C, the oblong square, opening as broad but not longer
than the same opening in the frame..
Fig. 4, No. 1, a top view of one end of a buckle or clasp con-
structed on the principle described in Fig. 1, but only made shorter,
and therefore dispensing with a portion of the centre frame A, is
the headpiece or frame with grooves A¹, B, and a square or other
shaped aperture at J, to receive the stud or stop shown in No..2;
the slide piece at I, attached to the spring G, fixed to the slide
piece F.

page_text: Fig. 5, a section through the centre of Fig. 4. No. 1, A, the
frame; J, the aperture. No. 2, F, the slide piece; G, the spring;
& I, the stud or stop..
I would here observe that the tug slide may in many instances
be made of the exact size given in the Drawing; but at the same
time may be varied in this respect, as also in regard to its orna-
mental character, without affecting the principle of my Invention.
The trace or other part where required, being furnished with a galva-
nized iron tube for the trace or strap to slide through the improved
tug slide before described, is next placed on the upper surface of
the leather cover, immediately over the plug of the galvanized iron
tube, for the purpose of keeping the plug in its proper place through
the trace or other part to which it is attached; & the tug slide
thus adapted facilitates the raising of the plug for the necessary
lengthening or shortening of the trace or strap. In adapting the
same Invention to the purpose of making buckles. or clasps, I have
described one mode of manufacturing the same; but I do not confine
myself to any particular size or figure, which may be varied to a
considerable extent in fastenings for harness, military accoutre-
ments, and other similar fastenings.
And having thus described the nature of my said improvements,
and how the same are to be carried into effect, I do declare my
claims to be,
First, for the peculiar construction of a tug slide with the place-
ment of the spring catch at the opening end for traces and other
parts of harness, as described:
Second, for the employment of a galvanized -iron tube in con-
nection with the tug slide: And,
Third, for the application of the principle of my improved tug
slide for the purposes of fastenings generally.

*
NOW KNOW YE, that I, the said James Chadnor White, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement:
My improvements consist, firstly, in an improved tug slide for
the better securing of traces; secondly, in the application of a
galvanized iron tube to traces, in connexion with the said tug slide;

page_text: and, thirdly, in a variation of the principle of the slide, by means of
which a buckle or clasp of a peculiar construction is produced.
For the better understanding of my said. Invention, I shall now.
proceed to give a particular description thereof, reference being had
to the Drawings hereunto annexed, in which the same letters and
figures denote corresponding parts throughout..
DESCRIPTION OF THE DRAWINGS. :
Figure 1, is a view of the face or top surface of one arrangement
of my improved tug slide for harness. A, B, is a metal frame
having an oblong square opening from C to D, and a groove cut
within it, on each side, extending from A to A¹, and from B to B'.
In this groove slides the oblong metal piece E, F, having a feather.
edge at A, and another at B", corresponding with the grooves
A, A', and B, B'. The slide E, F, carries a spring G, H, of which
the end H is concealed, and screwed underneath the slide. This.
spring must be placed underneath at the end E, of the slide piece;.
and to its other end is attached a square metal stud I, so arranged.
that the face of it shall be level with the main upper surface of the
frame A, and the slide E, and also exactly fill the corresponding.
aperture J, in the frame work when the slide is pushed home, that
is, when the end E of the slide is brought in a line with A, B, thus.
forming a stop, the spring preventing its return until pressed down:
for the purpose of releasing and pushing back the slide piece E, F.
Fig. 2, is a longitudinal section through the centre of Fig. 1.
A, B, the external frame; C, the centre aperture; B¹, the groove;
E, F, the slide piece; G, H, the spring; I, the square stud, capable
of filling the aperture J, when pressed therein by the spring; K, K,.
four pins or shanks cast on the underneath side of the frame, there
also being other four on the opposite margin of the frame. These:
are passed through the leather cover of the galvanized iron tube,
and rivetted over a brass or other metal plate (Fig. 5) placed inside.
the cover.
:
Fig. 3, is a top view of another arrangement of the tug slide;.
and Fig. 4, is a longitudinal section of the same, showing a mode of

page_text: dispensing with the aperture J, in Figs. 1, and 2; this part being
here represented a solid, and the stud I, being made to catch into a
notch on the underneath side J¹; and the under side plate N, of this
end of the tug side is soldered on, forming the box or end complete.
The end of the slide L, H, F, is cut through at the end L, from
a to b, by depressing which, the spring G, to which it is fastened, is
depressed, and the stud I released from the notch J. A boss is fixed
on the slide at C', to aid in withdrawing the slide; C, is a screwhole
in the lower plate of the frame.
Fig. 5, is a plan of the metal plate, with K³, K', eight holes corre-
sponding to the eight pins or shanks, Figs. 2, and 4, and having an
aperture at M, for a screw; C, the oblong square opening corre-
sponding to a similar opening in the frame.
Fig. 6, No. 1, is a top view of one end of a buckle or clasp con-
structed on the principle described in Fig. 1, but only made shorter,
and therefore dispensing with a portion of the centre frame. A, is
the head piece or frame, with grooves A', and B, and a square or
other shaped aperture at J, to receive the stud or stop shown in
No. 2, the slide piece at I, attached to the spring G, fixed to the
slide piece F.

Fig. 7, is a section through the centre of Fig. 6. No. 1, A, the
frame; J, the aperture. No. 2, F, the slide piece; G, the spring; I,
the stud or stop.
in many
instances
I would here observe, that the tug slide may
be made of the exact size given in the Drawings or as required, and
inay be variously constructed without affecting the principle of my
Invention; the trace or other part of harness where required
being furnished with a galvanized iron tube for the trace or strap
or other required part to slide through. The improved tug slide
before described is next placed on the upper surface of the leather
cover immediately over the plug of the galvanized iron tube, for
the purpose of keeping the plug in its proper place through the
trace or other part to which it is attached; and the tug slide thus
adapted facilitates the raising of the plug for the necessary length-
ening or shortening of the trace or strap.

page_text: In adapting my Invention to the purpose of making buckles or
clasps, I have described one mode of constructing the same, and I
have also described two arrangements of tug slides; but I do not
confine myself to any particular material, size, or figure, or number,
or situation of the respective parts, as my said improvements may
be varied to a considerable extent in forming harness fastenings, and
fastenings for military accoutrements, certain articles of jewellery,
and other like fastenings.
And having thus described the nature of my said improvements,
and how the same are to be carried into effect, I do declare that I
claim, namely,
First, the peculiar construction of a tug slide, with the particular
mode of placing the spring catch, as a fastening for traces and other
parts of harness:
Second, the employment of a galvanized iron tube in connexion
with the tug slide: And,
Third, the application of the principle of my improved tug slide
to the forming of buckles or clasps for the purposes of fastenings
generally, as described.
In witness whereof, I, the said James Chadnor White, have
hereto set my hand and seal, this Nineteenth day of August,
in the year of our Lord 1853.
