Complete Specification Left, 8th Dec., 1899-Accepted, 27th Jan., 1900
I, NORMAN TAILBY, of 76, Summer Row, in the City of Birmingham, Timber
Merchant, do hereby declare the nature of this invention to be as follows:-
My invention has for its object the production of a simple and reliable circular
saw guard that can be readily fixed in such a position as will not obstruct the
saw line and be adjustable to any size of saw for which a bench is suitable.
In the application of my invention I pivot a guard or supporting rod or stem,
preferably of wrought iron, upon a plate or base piece which is bolted on the
led or table of the saw bench near the rear or leaving end but away from the
saw line and the fence. The said pivotted rod or stem can be adjusted to any
required angle and secured thereat by means of a clamping bolt passing through
a slotted semicircular or sector like arm or bracket.
Upon the pivotted supporting rod or stem I place a sliding bracket or holder
which can be secured in any desired position on the rod by means of a clamping
screw. The said bracket or holder is bored to receive a sliding guard arm, prefer-
ably of circular section, which can be secured at any desired position by a clamping
and which is slotted transversely in a suitable position to receive a
rectangular or other shaped wrought iron. guard bar which projects towards the
front end of the bench near to the face of the saw for the purpose of preventing
a workman or other person from falling across the teeth of the same.
screw,
I also secure upon the guard arm a bracket or holder, adjustable in position,
for receiving the upper end of the riving knife, the lower end of such knife
being made to enter a purposely formed slot in the bench when using a saw of
large diameter or to project through the ordinary saw slot or aperture when a
smaller saw is in use.
In the event of the rising of a piece of wood with the rotation of the saw before
reaching the riving knife, the guard arm herein before described, will serve to
arrest its motion and prevent it from being flung back on to the operator.
The whole of the main parts forming my improved circular saw guards, com-
prising the main supporting rod or stem, the guard arm with the guard bar,
and the riving knife can be readily adjusted to suit saws of the different diameters
that can be used with any bench, and the said parts are all preferably formed
of wrought iron.

page_text: I, NORMAN TAILBY, of 76, Summer Row, in the City of Birmingham, Timber
Merchant, 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 has for its object the production of a simple and reliable circular
saw guard that can be readily fixed in such a position as will not obstruct the
saw line and be adjustable to any size of saw for which a bench is suitable.
The accompanying sheet of explanatory drawings, to be hereinafter referred
to, illustrate a saw guard as constructed and arranged in accordance with my
invention.
Figure 1 is a side elevation and Figure 2 an end elevation of the apparatus,
the same reference letters in the two views indicating the same parts.
In the application of my invention I pivot a guard supporting rod or stem
as A, preferably of wrought iron, and of a square section, upon a plate or base piece
which is bolted on the bed or table B of the saw bench near the rear or leaving end
but away from the saw line C and the fence D. The said pivoted rod or stem A
can be adjusted to any required angle and secured thereat by means of a clamping
bolt a passing through a slotted semicircular or sector like arm or bracket A¹.
Upon the pivoted supporting rod or stem A. I place a sliding bracket or holder E
which can be secured in any desired position on the rod by means of a clamping
screw c. The said bracket or holder is bored to receive a sliding guard arm F,
preferably of circular section, which can be secured at any desired position by
a clamping screw f, and which supports a rectangular or other shaped wrought
iron guard bar G. The said bar projects towards the front end of the bench
near to the face of the saw for the purpose of preventing a workman or other
person from falling across the teeth of the same.
I also secure upon the guard arm F a bracket or holder H, adjustable in
position, for receiving the upper end of the riving knife J, the lower end of such
knife being made to enter a purposely formed slot in the bench when using a
saw of large diameter, or to project through the ordinary saw slot or aperture
when a smaller saw is in use.
In the event of the rising of a piece of wood with the rotation of the saw before
reaching the riving knife J, the guard arm. F, will serve to arrest its motion
and prevent it from being flung back on to the operator.
The whole of the main parts forming my improved circular saw guards, com-
prising the main supporting rod or stem A, the guard arm F with the guard
bar G, and the riving knife J, can be readily adjusted to suit saws of the different
diameters that can be used with any bench, and the said parts are all preferably
formed of wrought iron.
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 circular saw guards, the combination with adjustable supports of a
guard arm as G at the side of the saw and a pivoted riving knife as J arranged
substantially as described and as illustrated.
2. In circular saw guards, the combination with a vertically adjustable
bracket or holder as E with a pivoted stem A and arm A¹ to which the said stem

substantially as and for the purposes described and as illustrated.
3. An improved circular saw guard constructed and arranged substantially
as described and as illustrated.
ated this 7th day of December 1899.
