Improvements in Squares.
I, FREDERICK FRELINGHUYSEN POOLE, of 26 Arch Street, Newark in the
County of Essex and State of New Jersey, United States of America, Carpenter,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a simple and durable square, which
can be easily taken apart and thus will occupy much less space in a tool box and
yet will be accurate in its work when in use.
The invention consists in the improved separable square, its locking mechanism,
and the arrangement and combination of the various parts thereof.
Referring to the accompanying drawings, in which like letters of reference
indicate corresponding parts in each of the several figures:
Fig. 1. is a plan view of my improved square, when ready for use,

each other,

and in a line parallel with said slot a locking pin a*.
The shorter or angle arm is provided with projections and 63, adapted to fit
in recesses a¹ and a³ respectively. Said projections, and recesses, are preferably
undercut.
In the arm is also arranged a recess or elongated slot 62, adapted to corre-
spond with slot a² of arm a and also an elongated slot 6, and a locking pin 6, in
reciprocate position to slot a³ and pin at of arm a, as clearly shown in the
drawings.

As clearly shown in the various figures, the arms a and b are at their joining
surfaces halved, so as to give, when in position and locked by the block
equal thickness and finished surface to the tool.
In Figs. 5 & 6 a modification is shown, whereby the two arms a and b are
pivotally connected to each other at m, and are provided with two locking blocks c,
arranged at right angles to the curved joints.
For said purpose each of the arms (a and b) is provided with two elongated
slots a and b, and with locking pins e and f and their corresponding recesses d
and g respectively.
In operation the halved portion of b is placed or laid on the halved portion,
of a, so that the pins a & 6 enter the enlarged portion of the elongated
slots & a.
The said parts are then slid together until the slot 6 of covers the slot or
recess a² of a, when the locking block c is moved over into position shown in
Dime 1 and 2

COMPLETE SPECIFICATION.
Improvements in Squares.
1, FREDERICK FRELINGHUYSEN POOLE, of Newark, County of Essex and
State of New Jersey, U.S.A., Carpenter, my Post Office address being 26 Arch
Street, Newark, New Jersey, U.S.A., do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of this invention is to provide a simple and durable square, which
can be easily taken apart and thus will occupy much less space in a tool box and
yet will be accurate in its work when in use.
The invention consists in the improved separable square, its locking mechanism,
and the arrangement and combination of the various parts thereof, substantially
as will be hereinafter more fully described and finally embodied in the clauses of
the claims.
Referring to the drawings filed with the Provisional Specification, in which
like letters of reference indicate corresponding parts in each of the several 'figures:
Fig. 1. is a plan view of my improved square, when ready for use,
Fig. 2. is a plan view of the same, the two parts being shown separated from
each other,
Fig. 3. shows in plan view a modification of the square,
Fig. 4. is a view similar to Fig. 2, illustrating the parts of the tool shown in
Fig. 3.
Figs. 5 & 6 are views of another modification and
Fig. 7. is a sectional view on line y, Fig. 1.
In said drawings a represents the longer arm of the square, provided with
recesses a¹, a² and a', as shown in Figs. 1 and 2. The recesses a¹ and a' are
preferably triangular shaped. In said arm a is also arranged an elongated slot a³
and in a line parallel with said slot a locking pin a*.
The shorter or angle arm is provided with projections 61 and 6, adapted to
fit in recesses a¹ and a respectively. Said projections, and recesses, are preferably
undercut.
In the arm is also arranged a recess or elongated slot 3, adapted to corre-
spond with slot at of arma, and also an elongated slot 6, and a locking pin b', in
reciprocate position to slot a' and pin at of arm a, as clearly shown in the
drawings.
In said slot or recess 6 is arranged a locking block c, adapted to slide in said
slot and also in slot a³ of arm a, when the tool is put together for use.
Instead of the recesses a¹ and a³ and the projections 6 and 6, a series of locking
pinster and with corresponding slots'd and 'g, may be used as in Figs. 3 & 4.
As clearly shown in the various figures, the arms a and b are at their joining
surfaces halved, so as to give, when in position and locked by the block c an
equal thickness and finished surface to the tool.
Un Figs. 5 & 6 a modification is shown, whereby the two arms a and b are
pivotally connected to each other at m, and are provided with two locking blocks c,
arranged at right angles to the curved joints.
For said purpose each of the arms (a and b) is provided with two elongated

page_text: slots a and b, and with locking pins e and ƒ and their corresponding recesses d
and 9 respectively.
g
In operation the halved portion of 6 is placed or laid on the halved portion
of a, so that the pins a & 64 enter the enlarged portion of the elongated
slots b & a.
The said parts are then slid together until the slot 6 of 6 covers the slot or
recess a of a, when the locking block c is moved over into position shown in
Figs. 1 and 3.
This method of placing and locking the two arms a and b together along with
the various undercut projections and their corresponding recesses, will give as
much rigidity to my square as a square made out of one piece of metal now
possesses.
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. The herein described square, one of the arms a being provided with a
triangular shaped recess a¹ at or near its center, and also provided with a triangular
shaped recess a³, the other arm b with projection band adapted to fit in said
recesses a¹ and a³ of arm a, slots a and b arranged parallel to each other in
arms a and b respectively, pins 6 and a secured to said arms, and adapted to fit
and slide in their respective slots, and a locking mechanism arranged at right
angles to said slots, substantially as described and for the purposes set forth.
2. The herein described square, one of the arms (a) being provided with a
series of locking pins e and at its outer edge with a series of recesses g, the other
arm b with recesses d and pins f, said recesses and pins being adapted to mesh
with the pins and recesses of arm a, elongated slots a and 66 arranged parallel to
each other in the arms a and b respectively, pins * and a secured to said arms
and adapted to fit and slide in their respective slots, and a locking mechanism
arranged at right angles to said slots, substantially as specified.
3. A square combining therein arms a and b of uniform shape and construction,
pins and grooves arranged alternately in each of said arms, a pivotal connection
arranged at or near the angle of said arms, and two locking devices arranged
alternately and when in normal position, at an obtuse angle to each other, all said
parts, substantially as described and for the purposes set forth.
