A Combination Square, Mitre, and Bevel.
1, VALENTINE BROUGHTON, of 7 Sandwell's Place, Halfords Lane Smethwick, in
the County of Stafford, Railway Coach Builder, do hereby declare the nature of this
invention to be as follows:-
My invention relates to the manner in which I construct a combined square mitre
and bevel. The object being to combine in one tool the usual independent square, the
independent mitre and the ordinary separate bevel.
I construct a combined square, mitre, and bevel according to my present invention,
either in metal or wood by forming the stock with the right angled blade rigidly
attached to it, but having working within the same stock another blade which can be
set to any angle and which can be moved freely upon a pin, screw or rivet which
passes through the sides of the stock and which serves to connect the two sides
together in the case where the stock is formed by two separate pieces being attached
rigidly one each side of the right angled blade.
sometimes employ an ordinary thumb nut and screw, to clamp the sliding bevel
blade in any desired position, or I employ an ordinary screw to tighten up with a
screw driver and thus to make the blado fast.
I graduate one or both of the blades with any suitable divisions or scales, having
inches and degrees set out thereon.
The sliding or bevel blade I form either in metal or wood with a long slot or hole
along its length to admit of the screw or pin passing through, and to enable the blade
to be readily moved into any desired position in relation to the stock.
I sometimes make the stock of sufficient length to receive the sliding blade quite
within it and thus to form as it were a protecting case for the blade which in no way
interferes with the usefulness of the combined tool.
I do not limit the construction of my stock to metal plates which are rivetted
together or cut out but sometimes cast the same in any suitable metal with the slot
within it to receive the blade.
I also arrange a scriber marker or pencil to attach to the stock by causing it to fit
into a suitable recess or groove formed within the stock.

COMPLETE SPECIFICATION.
A Combination Square, Mitre, and Bevel.
1 VALENTINE BROUGHTON of 7 Sandwell's Place, Halfords Lane Smethwick in the
County of Stafford Railway Coach Builder 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:-
My invention relates to the manner in which I construct a combined square, mitre
and bevel. The object being to combine in one tool the usual independent square,
the independent mitre and the ordinary separate bevel. 1 construct a combined
square, mitre, and bevel according to my present invention either in metal or wood,
by forming the stock with the right angled blade rigidly attached to it but having
working within the same stock another blade which can be set to any angle and which
can be moved freely upon a pin screw or rivet which passes through the sides of the

page_text: stock and which serves to, connect the two sides together in the case where the stock
is formed by two separate pieces being attached rigidly one each side of the right
angled blade.
I sometimes employ an ordinary thumb nut and screw, to clamp the
sliding bevel blade in any desired position, or I employ an ordinary screw to tighten
up with a screw driver and thus to make the blade fast. I graduate one or both of
the blades with any suitable divisions or scales having inches and degrees set out
thereon. The sliding or bevel blade, I form either in metal or wood with a long slot
or hole along its length to admit of the screw or pin passing through, and to enable
the blade to be readily moved into any desired position in relation to the stock.
I sometimes make the stock of sufficient length to receive the sliding blade quite
within it and thus to form as it were a protecting case for the blade which in no way
interferes with the usefulness of the combined tool. I do not limit the construction
of my stock to metal plates which are rivetted together or cut out but sometimes cast.
the same in any suitable metal with the slot within it to receive the blade.
I also arrange a scriber marker or pencil to attach to the stock by causing it to fit
into a suitable recess or groove formed within the stock.
In order that my invention and the method of carrying the same into effect may be
more readily understood, I append hereunto one sheet of explanatory drawings to
he hereinafter referred to. Figure 1 is a front elevation, and Figure 2 an end
elevation of my combined square, mitre, and bevel, in which A is the stock to which
is rigidly attached, at a right angle to it, the blade B, in the ordinary manner to form
the square. The stock A is formed with a narrow centre space or slot E (Figure 2)
suitable for the reception of the sliding blade C, and this sliding blade C is also
provided with a slot F, to enable the blade to be set at any desired angle, or its
position altered. When it is desired to fix this blade C at any given angle, the
screw D is tightened up, and the blade thereby clamped securely to the stock. The
screw I may be either a thumb screw operated by the fingers or provided with a
slotted head for use with a screw driver. As shown in Figure 1, the sliding blade is
set as a mitro, or at an angle of 45 degrees with the stock, but it can readily be
converted into a bevel and set at any desired angle by releasing the screw D and
setting the blade as required, as shown in Figures 3 & 4. When I require to use my
combination square, mitre, and bevel, as a square, I may turn the blade (about the
pin D, until it enters the slot formed in the stock A, as shown by dotted lines in
Figure 1, a stop S being secured within the slot to keep the blade parallel, and to
prevent it from projecting beyond the under side of the stock, such stop consisting of
a small stud, plate, or other equivalent. I sometimes graduate one or both of the
blades and also the stock, with any suitable divisions or scales, having inches and
degrees set out thereon, as shown in Figures 3 and 4. In Figure 5 I show my
combined square, mitre and bevel having a second slot G formed in the stock, at right
angles to the slot or narrow centre spacé E (Figure 2). By means of this slot, the
sliding blade together with its securing screw or pin D may be moved along the stock
and thus the blades may be set at any desired distanco apart. The dotted lines in
Figure 5 represent the blade C brought into close contact with the fixed blade B. In
Figures 4 and 51 also show a scribor H, which I sometimes carry in the stock G of
my combined square, mitre, and bevel by forming a dovetailed recess in the stock,
suitable for carrying a flat steel or other scriber with bevelled edges. The scriber is
thus flush with the edge of the stock and is at the same time kept in position therein.
When required for use, the scriber is drawn out from the end.
Having now particularly described and ascertained the nature of this my said
invention and the manner in which the same is carried into effect; 1 declare that
what I claim is :-
I. The construction of a combined square, mitre, and bevel with a sliding blade
capable of being secured at any desired position in the stock of the combined
tool, substantially as herein before described and illustrated in the accompanying
drawings.

page_text: II. The combination and arrangement of a square with a moving adjustable blade
substantially as hereinbefore described and for the purposes set forth.
III. The construction and arrangement of a combined square and adjustable angle
blade having a scriber pencil or marker secured to the stock as herein before described
5 and illustrated in the accompanying drawings.
