Improvements in Means for Planing, Filing, or otherwise Reducing
the Thickness of Wood Cuts and Electro-plates.
I, MICHAEL PATRIC KENNA, a citizen of the United States, residing at the City
and County of Dubuque, and State of Iowa, United States of America, Press-man,
do hereby declare the nature of this invention, and in what manner the same is to
he performed, to be particularly described and ascertained in and by the following
statement:-
It is the object of my invention to provide a simple, convenient and inexpensive
planer or shaving machine for planing off the under surface of cuts, electro-types
and the like, to make them of uniform thickness and the thickness of the length of
the type with which they are set for printing.
To aid in more fully understanding my invention, attention is invited to the
accompanying drawings which form a part hereof, and in which,
Fig. 1, is a perspective of the planer,
Fig. 2, is a view of the underside of the type-high gauge or frame for holding the
cut for planing, and
Fig. 3, is a cross section of one form of a knife or cutter.
Like letters of reference denote corresponding parts in all of the drawings.
In the drawings. A, represents the base of the planer, to which is cast integral
therewith the side pieces B. The upper surface of the pieces B, are in the same hori-
zontal plane and are preferably smoothed or polished. Within the upper surface of each
side piece B, is a recess a, into which a knife presently to be described, is secured by
the screws b. The cutting blade C, may be made of steel with its upper surface c,
level with the side pieces B, and its under surface beveled as shown in section in
Fig. 3, and set diagonally in the sides of the bed. The ends d, are preferably square
to fit into the recess a, in the side pieces B, and hold the cutter blade firmly.
To the bed A, of the planer, and just in front of the cutter edge of the blade 0,
adjustably secured the gauge D, by the screws e, for the purpose of determining
the thickness of the chip which the cutter will remove at any one time or at any one
If the cutter C, be a file or a sand paper bar, then the gauge D, may be
dispensed with..
cut.
In Fig. 2, is shown the underside of the type-high gauge and the holder in which
is set the cut or electro-plate about to be planed. This consists of an iron plate E,
having the type-high gauge, and the side strips g. The type-high gauges, are
of the thickness of the length of ordinary type and their lower surfaces are in the
same plane with each other and also either polished or made smooth, to adapt them
to slide along upon the upper surface of the side pieces B. The projecting strips 9,
are adapted to slide on the outside of the side pieces B, to guide its movements.
Through one side of the gauge f, are set a series of set screws H, which project
through the bed of the holder and are used for the purpose of holding the cut firmly
in the holder. To the upper side of the holder are handles G, for the purpose of
operating the same.
A convenient mode of operating my device is as follows. The cut K, is placed
in the upper part of the holder E, with one of its sides resting against a side of the
gauge, and its end against the end of the gauge or holder. A key h, is inserted
between the cut K, and the gauge if the cut is smaller than the gauge. Then the set

crew H, is turned until the cut is firmly held in position. The upper portion of the
holder is then turned over and the article to be planed rests upon the gauge D. The
operator then grasps the handle G, and pushes the gauge across the knife, taking off a
thin shaving and so on until the gauge will pass along over the knife and along on the
upper surface of B. When this occurs the cut is just type-high, from the fact that
the gauges f, are of the same depth as the length of the type. The same process
would be gone through with if the blade C, were a file or a sanded bar.
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:
1. In a machine of the character described, a gauge for holding electro-plates to
be planed or shaved, having a plate E, one or more type-high gauges secured to said
plate, means for rigidly securing an electro-plate on said plate, and a cutter for
shaving said electro-plate, for the purposes shown.
2. A machine of the character described, consisting of a bed A, having sides B,
cutter C, gauges D, and a holder with a handle for operating the same and having
one or more type-high gauges f, projection g, and set screw H, all combined to
operate as and for the purposes shown.
3. A machine of the character described, consisting of a bed plate with parallel sides,
a cutter set in said sides flush with the same, a gauge for said cutter, a holder for the
electro-plate, having one or more type-high gauges adapted to be moved along on
the sides of the bed, and means for holding the electro-plate in said holder, as and
for the purposes shown.
4. A machine of the character described, consisting of a bed with parallel sides, a
cutter set with its upper edge flush with the top of said sides and at an angle to said
sides, a gauge for said cutter, adjustably set in the bed, a holder provided with a
type-high gauge having projections adapted to compass the side pieces of the bed,
means for adjustably holding the electro-plate within the holder and handles for
driving the holder with the electro-plate secured therein over said cutter, whereby
the cut is shaved or planed to the thickness of said gauge, for the purposes shown.
