page_text: A communication from JAMES SAMUEL FOLEY and JOSEPH RUSE, both of the City of
Chicago, in the County of Cook, in the State of Illinois, one of the United States
of America, Manufacturers.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. 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 relates to a simple, cheap and durable device that is applicable for
use in the sharpening of tools and especially in the sharpening of engravers tools; the
object of the invention being to provide for the holding of the tool at any desired
angle and for an adjustment so that the tool may be sharpened with or across the
grain of the metal, all as will be hereinafter more fully described.
Reference is to be had to the accompanying drawings forming a part of this
specification in which similar figures of reference indicate corresponding parts in
all the views.
Fig. 1 is a plan view of the tool holder representing the parts as they appear when
adjusted to hold the tool at times when it is desired to sharpen it with the grain of the
metal.
Fig. 2 is a central sectional elevation the view being taken on line x-x of
figure 1.
Fig. 3 is a front elevation of the tool holder parts being shown in section.
Fig. 4 is a side view of the holder representing the parts as they appear when
adjusted to hold the tool at times when it is desired that the sharpening shall be done
across the grain of the metal of which the tool is made; and
Fig. 5 is a detail view of the clamp through which the tool is passed.
In the drawings 10 represents a plate which constitutes the main frame of the tool
holder said plate being mounted upon two castors 11 the shanks of which pass upward
through apertures formed in the plate to be engaged by thumb nuts 12 the arrange-
ment being such that when the thumb nuts are turned down the castors will be held
in rigid connection with the plate. The plate 10 is formed with a central projection 13
upon which there is mounted a central and vertically slotted post or standard 14 the
post being held to the plate by a screw 15 the shank of which passes through an
aperture formed in the plate to engage with a threaded socket formed in the post or
standard 14.

page_text: A tilting shaft 16 is carried by the post or standard 14 the shaft being formed with
an eye 17 which enters the slot of the post 14 and through the apertures of this eye 17
there is passed a clamping screw 18 the point of said screw engaging with a threaded
aperture that is formed with the post or standard 14 as shown best probably in
figure 3 the arrangement being such that the shaft 16 may be rocked upon its
connection with the standard and clamped in any desired position by turning home
the screw 18.
One side of the shaft 16 is slightly flattened as shown at 2 and extending inward
from this flattened side there is a slot that is entered by a clamping slide 20 said
slide being formed with an aperture 4 adapted to receive the tool to be sharpened.
This slide 20 has a threaded shank 19 which extends to the rear through an aperture
formed in the shaft 16 there to be engaged by a long nut 21 which has a milled
head 22.
When it is desired to sharpen a tool with the grain of the metal, the tool is inserted
in the aperture 4 of the sliding clamp 20 and the nut 21 is turned so that the
back of the tool will be clamped closely against the flattened face 2 of the shaft 16 the
shaft at this time being locked to its standard at the desired angle and the standard
being locked to the plate 10 by the screw 15 while the rollers of the casters 11 extend
at right angles to the length of the plate 10.
When the parts have been adjusted as described, the holder is placed upon the
upper surface of an oil stone or other sharpening device and the holder and the tool
carried thereby are moved back and forth over the face of the stone and it will be
seen that the tool may be brought to bear upon the stone surface at any desired
angle.
When it is desired to sharpen the tool across the grain of the metal the casters are
shifted so that they will run in lines parallel with the length of the plate 10 as
represented in figure 4 the shaft 16 is tilted to the position in which it is shown and
the tool is clamped to place extending downward between the casters 11 and the parts
being so adjusted that the tool and its holder are reciprocated above the surface of the
sharpening stone.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondents, and in what manner the same is
to be performed, I declare that what I claim is :-
1. The combination with a plate of casters connected there to a tilting shaft carried
thereby and a tool clamp arranged in connection with the shaft, substantially as
described.
2. The combination with a plate of casters carried thereby a tilting shaft supported
upon the plate and formed with a slot adapted to receive a tool clamp said tool clamp
and a clamping nut arranged in connection therewith, substantially as described.
3. The combination with a plate of casters adjustably connected thereto a standard
also adjustably connected to the plate a shaft adjustably connected to the standard and
a tool clamp carried by the shaft substantially as described.
4. The combination with a plate of casters 11, thumb nuts 12, arranged in connec-
tion with the casters, a standard 14, a screw 15 arranged in connection therewith, a
shaft 16 having a flattened face 2, and a recess 3, a thumb screw 18 by which the
shaft 16 is connected to the standard 14, a tool clamp 20 having an aperture 4 and a
shank 19 and a nut 21, arranged in connection with the tool clamp, substantially as
described.
