Improvements in Size Sticks or Measures.
Year: 1896

page_text: I, WILLIAM BEADLE DAY, of 70, Hanley Road, Stroud Green, in the County
of Middlesex, Manager, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in the construction of size sticks or
measures.
In size sticks or measures as hitherto constructed the movable or sliding part
or foot soon becomes loose and fails to give accurate measurements in consequence
of the sliding foot not maintaining a perfectly perpendicular position with relation
to the graduated rod or rule.
The object of my invention is to ensure the sliding foot always keeping at a
right angle to the graduated rod or quite parallel with the fixed part or foot and
to be firmly held in the position to which it is adjusted. For this purpose I
provide it with a trigger or lever carrying a projection which projection is normally
pressed by a spring against the rod or measure, thereby keeping the sliding foot
in an absolutely perpendicular position at any part of the rod to which the sliding
foot is placed. To move the said foot it is simply necessary to press the trigger
lever so as to compress the spring and so relieve the rod from the pressure of the
projection on the trigger. When the foot has been adjusted to the required
position on the rod or measure the trigger is released and the projection pressing
on 'the rod will firmly hold the foot in position.

Improvements in Size Sticks or Measures.
I, WILLIAM BEADLE DAY, of 70, Hanley Road, Stroud Green, in, the County
of Middlesex, Manager, 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:-

to the graduated rod or rule.
The object of my invention is to ensure the sliding foot always keeping at a right
angle to the graduated rod or quite parallel with the fixed part or foot and to be
firmly held in the position to which it is adjusted. For this purpose I provide it
with a trigger or lever carrying a projection, which projection is normally pressed
by a spring against the rod or measure, thereby keeping the sliding foot in an
absolutely perpendicular position at any part of the rod to which the sliding foot
is placed. To move the said foot it is simply necessary to press the trigger lever
so as to compress the spring and so relieve the rod from the pressure of the projec-
tion on the trigger. When the foot has been adjusted to the required position
on the rod or measure the trigger is released and the projection pressing on the
rod will firmly hold the foot in position.
To enable my invention to be fully understood I will describe it by reference
to the accompanying drawing, in which:-
Figure 1 is a sectional elevation of a size stick made according to my invention;
Figure 2 is a plan of the size stick; and
Figure 3 is a section on the line 3-3 Figure 1.
a is the ordinary graduated rod and b is the fixed foot thereof. c is my sliding
foot, made hollow as shewn in Figure 1, and d is the trigger or lever, the said lever
being pivoted at e to the sliding foot and having at the end of its shorter arm,
which extends into the sliding foot, the projection or recessed disc f provided with
an elastic pad f. g is the spring which is arranged in the hollow sliding foot and
bears at its upper end against the upper part of the sliding foot and at its lower
end against the recessed portion of the disc f.
With this construction it will be obvious that the sliding foot c is normally held
in position on the graduated rod a by the spring pressing the pad f against one
rod. To move the said foot it is simply necessary, as above stated, to press the
lever so as to compress the spring 9 and relieve the rod a from the pressure of
the pad f¹. When the sliding foot 6 has been adjusted to the required position on
the rod a it can be firmly held in this position by relieving the lever d from
pressure thereby allowing the spring g to press the pad f¹ into contact with the
rod. The foot is also provided with a guide h which assists in keeping the foot at
right angles to the rod a.
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. A size stick having a recessed sliding foot g and a trigger or lever pivoted
thereto, one arm of the said lever extending into the sliding foot and being
normally pressed into contact with the graduated rod of the size stick by a spring
arranged in the recessed sliding foot, substantially as hereinbefore described and
illustrated.
2. The manufacture and use of the improved size stick or measure herein before
described and illustrated in the accompanying drawing.
