An Improved Adjustable Scoring Tool for use in the Manufacture of
Harness, Boots and Shoes, and the like.
I, JOHN CHARLES PARKER, of No. 1, Fieldslea Terrace, Poole Road, Parkstone,
in the County of Dorset, Hardware, Leather and Grindery Dealer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement: —
This invention relates to an improved adjustable scoring tool for use in harness-
making, boot-making and the like, and has for its object to provide a tool of this
description which shall be capable of accurately scoring leather or similar
material with suitable patterns or marks, such as those required for indicating
the places where the stitches have to be sewn in the manufacture of harness,
boots and shoes and the like, such tool being provided with an adjustable guide
whereby the scoring or spacing marks are caused to follow perfectly parallel
lines with the edges of the material, the distance of the said scoring or spacing
marks from the edges of the material being regulated at will.
In order that this my said invention may be the more readily understood and
carried into practical effect, reference is hereby made to the accompanying sheet
of illustrative drawings, wherein :-
Fig. 1 is a side elevational view of the complete scoring tool.
Fig. 2 being an underside view thereof, while
Fig. 3 is a view of a detail.
Referring to the drawings, wherein like letters of reference indicate corres-
ponding parts throughout both figures, a represents an upwardly inclined wooden
or other handle in which is fitted a metal shank b.
The forward end of the shank b is bifurcated as at b, and between the jaws
formed by such bi-furcation is mounted a scoring-wheel c, the teeth of which
are pointed at their ends so that when the tool is passed over the surface of the
leather or like material, such pointed teeth will score or indent the material to
a sufficient depth.
The axle c carrying the scoring-wheel c is preferably in the form of a screw
having a smooth central portion and a slotted head 2, so as to allow of ready
removal of such axle from the bifurcated end of the shank b when it is desired to
substitute another scoring-wheel of a different size for the one previously used.
d represents a plate having a rectangular adjusting arm e at a right angle
thereto, such arm projecting from the upper side of the said plate and being
located at the rear end thereof.
The said arm e is provided with a lengthwise slot e¹ through which passes the
shank of a set-screw f which set-screw also passes through the shank of the tool
and is provided on its lower end with a head f
g is a winged nut working on the upper end of the set-screw, and by means of
which the slotted arm e is fixed in its adjusted position.
The forward end of the plate d is bi-furcated and has mounted therein a guide-
ED 077

page_text: roller h, said guide-roller being loosely mounted on a spindle i having rigid
bearings in the bi-furcated end of the plate d, or such roller may be rigidly
mounted on a spindle which is free to revolve in bearings in the said bifurcated
end of the plate.
It will be understood from the foregoing description, and as shewn by the
drawings, that the guide-roller is mounted at right angles to the scoring-wheel.
In operation the guide-roller travels along the edge of the leather or other
material to be scored, the distance of the scoring-wheel e from the edge of the
material, whose conformation it is desired such wheel shall follow, being regu-
lated by the adjusting means herein before described.
Sufficient pressure is brought to bear upon the tool in order that the pointed
teeth of the scoring-wheel c may penetrate or indent the surface of the material
over which such wheel is travelling, to a sufficient depth in order to indicate the
spaces where the stitches are to be inserted.
Although I may employ the tool for the purpose of punching the necessary
holes in the material to be sewn, yet I prefer to employ such tool simply for the
purpose of scoring such material, the necessary stitch-holes being subsequently.
made by an awl or other punching tool.
In addition to scoring leather and the like for sewing purposes, my invention is
applicable also for scoring ornamental patterns or designs on the surfaces of
suitable materials.
Having now particularly described and ascertained the nature of my said in-.
vention and in what manner the same is to be performed, I declare that what
I claim is:
1. The improved leather-scoring tool for use in the manufacture of harness,
hoots and shoes, and the like, consisting in a handle provided with a metal
shank having a bi-furcated end in which is removably mounted a scoring-wheel;
and a guide-roller mounted at right angles to said scoring-wheel in one end of
a plate carrying at its other end, upon the upper side thereof, a slotted arm
Through which, and the shank of the tool, passes a headed set-screw on which
works a winged nut and by means of which the relative distance of the roller
from the scoring-wheel can be adjusted, substantially as described and shewn.
2. In leather-scoring tools, the combination of an upwardly inclined handle a
having a shank , bifurcated at its free end in which bifurcated end a scoring-
wheel is removably mounted upon a headed axle c¹ having a screw-thread at each
end and a smooth central portion; with a guide roller mounted in the forward
end of a vertical plate 7, said plate having upon its other end an arm projecting
inwardly toward the said shank, said arm being slotted at e¹ for the reception of
a headed set-screw f which passes through said slotted arm and through the
shank b, the upper end of said set-screw being provided with a winged nut g,
all arranged, combined and operating substantially as and for the purpose herein-
before described and as illustrated by the drawings.
