Complete Specification Left, 29th May, 1893-Accepted, 1st July, 1893
PROVISIONAL SPECIFICATION.
Improvements in Vertical and Horizontal Planing Machines.
I, JOSEPH BARROW, of the firm of Thomas Shanks and Company, of the
Union Iron Works, Johnstone, in the County of Renfrew, North Britain, Engineer,
do hereby declare the nature of this invention to be as follows, that is to say:-
My said invention relates to a class of planing machine constructed for moving
one or more tools in either a vertical or a horizontal direction upon fixed work;
and it comprises improvements admitting of the tool holders being very easily
fixed at any part of the tool plate or saddle, or piece or pieces which carry them,
and of two or more tool holders being fixed at different distances apart, in a manner
securing rigidity without possibility of displacement and consequently insuring
accuracy in the work done.
My invention consists in forming on the tool plate and other parts, preferably
by planing, serrations, or corrugations, or a series of comparatively narrow and
shallow grooves, the contact faces of the tool holders, tool holding bars, or other
parts having counterpart serrations, corrugations, or grooves formed on them.
Each tool-holder, or tool-holding bar is secured in any desired position on the tool
plate or on one or more brackets by one or more buckles or frames encompassing
them and movable in T-grooves, through the outer part of each of which buckles
screw pins are tapped to clamp the tool-holder or bar in position with its serrations
or corrugations engaging with those of the part on which it is fixed. The brackets
when used may be secured in position on the tool plate in a similar manner, or such
brackets may be simply bolted to the tool-plate.
The tool-holders or tool-holding
bars are by preference formed with the serrations or corrugations on two of their
faces at right angles to each other.

COMPLETE SPECIFICATION.
Improvements in Vertical and Horizontal Planing Machines.
I, JOSEPH BARROW, of the firm of Thomas Shanks and Company, of the Union
Iron Works, Johnstone, in the County of Renfrew, North Britain, Engineer, 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, that is to say :-
My said invention relates to a class of planing machine constructed for moving
one or more tools in either a vertical or a horizontal direction upon fixed work;
and it comprises improvements admitting of the tool holders being very easily fixed
at any part of the tool plate or saddle, or piece or pieces which carry them, and
of two or more tool holders being fixed at different distances apart, in a manner
securing rigidity without possibility of displacement, and consequently insuring
accuracy in the work done.
My invention consists in forming on the tool plate and other parts, serrations
or corrugations, the contact faces of the tool-holders or other parts being formed
with counterpart serrations. Each tool holder is secured on the tool plate or on
brackets by buckles the serrations of the parts engaging with each other; and the
tool holders are by preference formed with serrations on two of their faces at
right angles to each other.

page_text: And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing parts of a vertical and horizontal planing
machine as made with my improvements.
Figure, 1, of the drawings is a plan and Figures, 2, and 3, are elevations as at
right angles to each other.
Figure, 4, is an enlarged section showing the form of grooves which I prefer.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In carrying out my invention I form on the tool plate, A, and other parts,
preferably by planing, serrations or corrugations or a series of comparatively
narrow and shallow grooves, B, the contact faces, C, of the tool-holders or tool-
holding bars, D, having counterpart serrations, corrugations or grooves formed on
them. Each tool-holder or tool-holding bar, D, can be secured in any desired
position directly on the tool plate, A, but is by preference fixed on brackets, E, on
the tool plate by means of buckles or frames, F, encompassing them and movable
in T-grooves, G, formed in the brackets, E, and through the outer part of cach of
which buckles, screw pins, H, are tapped to clamp the tool-holder or bar, D, in:
position with its serrations or corrugations or grooves, B, engaging with those of
the bracket on which it is fixed. The brackets, E, might be secured in position on
the tool plate, A, in a similar manner, but they are preferably adjustably bolted.
to the tool plate which has T-grooves, K, formed in it so that the bolts, L, fixing the
parts together can be moved up and down. The tool plate, A, has several of these
T-grooves, K, formed in it so that the distance between the brackets, E, can be
varied for different work. The tool-holders or tool-holding bars, D, are by
preference formed with serrations or corrugations, B, on two of their faces, C, at
right angles to each other, to allow of their being secured in either of two positions,
and they are fixed at some distance from each other the one being near the top of
the brackets, E, and the other on the bottom of the brackets which are preferably
of a modified right-angle triangular form.
The tools or cutters, M, may be fixed to the bars, D, in various ways. In the
drawings they are shown as fixed in blocks, N, bolted to the ends of the bars.
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 :-
:―
In planing machines of the kind hereinbefore indicated, forming the tool plate
and tool-holding bars with serrations, corrugations, or grooves, the tool-holding
bars being adjustably clamped by buckles either directly on the tool plate or on
brackets which are also formed with serrations, corrugations or grooves and are
adjustably secured to the tool plate substantially as and for the purposes herein-
before described.
