RICHARD WILLIAM TAYLER, Avenue Villa, Fornham Road, Bury St. Edmunds,
in the County of Suffolk, Engineer, do hereby declare the nature of this inven-
tion to be as follows;-
The said improvements have for their object to guard or fence circular saws of
varying diameters when such saws are used interchangeably in one and the same
saw bench.
to
For this purpose a
combination of levers and two or' more metal
plates or shields forming segments of circle corresponding to the
diameter of the largest saw, are employed and pivoted and arranged
in relation one to another in such a manner that they may be closed
guard or fence each saw from the largest to the smallest and by the reverse action
opened to return to the former position in the following manner. A pedestal or
bracket is constructed to be fixed to the top or table of a saw-bench having an arm
extended to carry a head and moveable slide to the vertical plane of the circular
saw the said slide being operated by a suitable set bolt. To the said slide arcs
of the same circle are pivoted in such a manner as to form a moveable or
pivoted X the two upper halves of which are connected by two levers to the head
suspended in the plane of the saw and the two lower halves of the pivoted X
receive the metal segments or shields in the following manner. The, metal
segment or shield intended to guard the back of the largest saw is attached to the
left hand lower half of the arc in the moveable X so as to fall in the plane of
the saw and the metal segment or shield intended to guard the front of the saw
is attached to the right hand of the lower half of the arc in the moveable X in a
similar manner so that when the moveable slide is released from the position which
holds both shields in the plane of the saw and allowed to descend the metal shields
are closed by the action of the levers which are connected to the head operating
the pivoted X so as to enclose or guard saws of a lesser diameter and vica versa
l'art of the metal shield guarding the back of the saw decends beneath the table.
And the part of the metal shield guarding the front of the saw is subject to regula-
tion and adjustment by means of suitable quadrant and set bolt.

I, RICHARD WILLIAM TAYLER, of Avenue Villa, Fornham Road, Bury St.
Edmunds, in the County of Suffolk, Engineer, do hereby declare the nature of this
[Price 8d.]

page_text: 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 improvements in guards or fences for circular saws
and has for its object to provide a guard or fence which can be used. with circular
saws of different diameters when such saws are used interchangeably in one and
the same saw bench.
To this end I provide an arrangement of levers and two or more metal plates or
shields forming segments of a circle corresponding to the diameter of the largest
saw to be used in. the bench, the said levers being so arranged and pivoted to a
slide working in a fixed head to which the levers are connected that the shields
can be closed to guard or fence saws of different diameters by adjusting the
position of the slide as hereinafter described.
In the accompanying drawing,
Figure 1 is a side elevation of a saw bench having my improved guard or fence
applied thereto; and,
Figure 2 is a front elevation thereof:
Figure 3 is a section on the line 3-3 Figure 1.
a is the saw bench and b, b1 represent two saws of different diameters to illus-
trate the method by which my gear can be employed for fencing saws of different
diameters as hereinafter more particularly described. c is a pedestal or bracket
which is adapted to be fixed (by bolts or other suitable means) to the table of the
saw bench a, and d is an arm with which the said pedestal c is provided, the said
arm d carrying at its free end a head e which is pivoted thereto by the bolt e¹.
The head e carries a slide f which is movable in a vertical plane and can be secured
in any desired position in the said head e by means of a set screw f¹ which passes
through a slot in the said slide f. To the slide f there are pivoted
two levers g, g in such a manner that they form a cross and the upper ends of
these two levers g, g are connected by levers or links h, h to the head e upon the
arm d. i, are the metal segments or shields which are secured to the lower ends
of the two pivoted levers g, the dimensions and the position of the parts being
such that these two shields i, are held in the plane of the circular saw.
The shield which is intended to guard the back of the saw, is rigidly secured
to its lever g whilst the metal segment or shield i which is adapted to fence the
front of the saw, is adjustably secured to its lever g by means of a slide g¹ and set
screw. The shield passes through the slot in the table of the saw bench
when the guard is to be employed for a small saw as hereinafter described.
are
With this arrangement, to adapt the guard to saws of different diameters it is
only necessary to suitably adjust the slide f in the head a By placing the said
slide f in the position shown in full lines in the drawing, the guards,
opened out so as to receive the largest saw band by lowering the slide f in the
head e, the guards are regulated so as to gradually take saws of diminishing
diameter until the smallest saw b can be suitably guarded as illustrated by the
broken lines. The guard for the back of the saw passes, as above mentioned,
through the slot in the table a, whilst the guard i for the front of the saw must be
slid upwards in its guide gas indicated in the dotted lines.
When the saw is to be changed or sharpened the device, can be swung out of the
way upon the pivot e¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is-
1. In guards or fences for circular saws, the employment of an adjustable head
carrying a slide to which are pivoted two levers carrying at one end front and
back guards for the saw and being connected at the other end to the fixed head
by links substantially as, and for the purpose, herein before described.
2. In circular saw guards of the kind described in Claim 1, the arrangement of

described and illustrated.
3. The combination and arrangement of parts forming the improved adjustable
guard or fence for circular saws hereinbefore described and illustrated in the
accompanying drawing.
