PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting Glass Tubes, Plates, and
other articles.
I, JONATHAN ODELL FOWLER Jr. Solicitor, of 165 Broadway New York,
County and State of New York, United States of America, do hereby declare the
nature of my said invention to be as follows:
My invention relates to appliances designed to incise articles-as for example
glass tubes or plates etc.-and has for its object the provision of two parallel jaws
or arms adapted to be held apart as by springs. In one form of my appliance
the rear portion of the lower jaw is provided with two standards which work in two
orifices formed in the rear part of the upper jaw, on which standards are placed
spiral springs. A handle is preferably fulcrumed to the top of the rear standard.
At or near the extremity of the upper jaw is located a cutting tool-as a steel
disc and at the corresponding end of the lower arm is preferably secured a clamp
or flange. A collar provided with a projecting annular flange works on the upper
arm which is ordinarily marked with graduations of the inch and fractions thereof.
In another article constructed according to my invention the jaws are provided
at their rear ends with grooves or threads adapted to engage with an interiorly
threaded handle so that by turning the handle around the jaws will approach each
other.
In other appliances it is obvious that either one of the arms or jaws may be
stationary, or both may have some movement, or the two jaws may normally lic
close together and be pulled apart to admit of the entrance of the glass.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Cutting Glass Tubes, Plates, and
other articles.
I, JONATHAN ODELL FOWLER Jr. of 165 Broadway New York, New York
State, United States of America, Manufacturer, do hereby declare the nature of
my said 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 appliances designed to incise articles-as for example
glass tubes or plates-& has for its object the provision of a device, simple in
construction, inexpensive in manufacture & efficient in practical use.
To attain the desired end my invention consists in the construction and arrange-
ment of parts first fully described & then pointed out in the claims.
In the drawings which form a part of this Specification Figures 1 & 2 represent
side elevations of articles constructed according to my invention & Figures 3, 4 & 5
are partial side elevations of other tools so constructed.
Like letters of reference wherever they occur indicate corresponding parts in all
the figures.

page_text: Referring again.to the drawings A, A' represent two practically parallel jaws or
arms adapted and preferably arranged to be normally held somewhat apart as by
springs B, B and upon manipulation, as by the use of a handle, as C, or H, to
approach each other ordinarily on opposite sides of the material to be operated
upons &to continue in a parallel, or approximately parallel relation while so
approaching each other or travelling away from one another.
It is obvious that many methods of construction & arrangement of parts may be
utilized to accomplish this action of. the two arms or jaws. A, A', but one of the
most simple & preferable instruments of this kind is made & operated in the
following manner:
The rear portion A³, of the arm or jaw A', is provided with two standards a, a²,
which work in two orifices a, a³, formed in the rear part A, of the arm A, on
which standards are placed spiral springs B, B1, which springs serve to separate
the parts.
The jaws A, A, may, by being grasped directly by the hand, be caused to
approach each other, but for convenience I prefer to use, in connection with the
same a handle or lever C, which controlling handle is fulcrumed at c, to the top. of
the standard or post a¹, and serves upon manipulation, to cause the arm A, to
. approach the jaw A¹.
At or near the extremity of the arm or jaw A, is placed a cutting tool as the
steel disk E, & at the corresponding end of the other arm A, is preferably located
a clamp, as a flange D, which serves as a rest for the glass & which when the parts
are closed together, abuts against the exterior of the glass to be cut, & together
with the cutting disk E, placed upon the opposite jaw or arm A, serves to hold
the glass steadily in position while the incision is being made. It is obvious that a
diamond or other cutting material may be inserted in the arm A, as a substitute for
the rotary cutter E.
A collar F, is bored or otherwise adapted to slide freely on one of the arms & is
preferably formed with a projecting annular flange. This collar serves as a guide
for the edge of the glass & may be provided with a set-screw, by which the collar
may be set & secured at any required point on the arm which is ordinarily marked
with graduations of the inch & fractions thereof as G, in order to show the distance
between the edge of the cutter E, & the collar F.
Although primarily designed for tubes, yet it is evident that my cutting
instrument may be used to operate upon glass plates, rods, bars, etc.
Another article constructed according to my invention is shown in Figure 3,
where the jaws A, A', are provided at their rear ends A', A', with inclines having
segmental spiral grooves or threads a, a, adapted & arranged to engage with
the controlling handle H, in such a manner that upon manipulation of the handle,
as by turning the same around, the springs B' B, are compressed. & the arms or
jaws A, A', will approach each other meanwhile maintaining their parallel relation.
In operating with my tool the collar is first adjusted at any required distance from
the cutter E, in cases, where a collar is used, & the instrument being held in one
hand & the glass to be cut being inserted between the parallel or approximately
parallel arms or jaws A, A, the latter are gently forced toward each other until
the glass is firmly grasped by the appliance. Then by moving the glass along
between the cutter E & the arm A, an incision will be produced on the surface of
the glass & a channel cut therein, whereupon by slightly knocking or jarring the
same, the portion of the glass desired to be removed will fall off, the separation
having occurred on the line previously marked by the rotary cutter E.
It is obvious that either one of the arms or jaws may be stationary as in
Figure 1, or that both of the same may have some movement as 'in' Figures 2, 3,
& 5, or that if preferred the 'two jaws may normally lie close together as in
Figure 4, & be pulled apart so as to admit of the entrance of the glass between the
same, in which case the two jaws will recede from each other & again approach one
another maintaining all the while an approximately parallel relation.

page_text: 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-A hand glass cutter consisting of two arms or jaws, one provided with a
cutter, & the other adapted to serve as a rest or clamp for the glass & arranged
to reciprocate, in combination with means for holding the same in a practically
parallel position, the two jaws being adapted & arranged upon manipulation to
maintain a substantially parallel relation while one arm is moving toward or from
another, or both arms are moving to and from each other.
2-In a hand glass cutter the combination with the two arms, one carrying a
cutter & the other a rest for the glass and arranged to reciprocate, of the vertical
guides for preventing the arms getting out of the same plane with one another.
3-In a hand glass cutter the combination with the two arms, one carrying a
cutter & the other a rest for the glass, & arranged to reciprocate, of the vertical
guides & springs.
4-In a hand glass cutter, the combination with the two arms, one carrying a
cutter & the other a rest for the glass & arranged to reciprocate & to approach
& recede from each other parallel or substantially parallel, of an auxiliary
mechanical device applied upon or connected to the aforesaid arm or arms for
operating an arm or arms.
5-In a hand glass cutter the combination with the two arms, one carrying a
cutter & the other a rest for the glass & arranged to reciprocate & to approach
each other parallel or substantially parallel, of the threaded inclines & the revolving
annular internally threaded handle.
6 A glass cutter comprising a bar with a cutter at one end, said bar being
attached at or near the other end to another bar carrying a suitable bearing
opposite the cutter of the first bar, the bars being so constructed as to permit
movement towards & from each other, & having an auxiliary connecting device
connected to or bearing upon each bar, & with a projecting lever handle whereby
the bars may be pressed toward each other during the cutting.
