PROVISIONAL SPECIFICATION.
Improvements in Cutters for Cutting and Shaping Metal Rods.
I, JOHN BRIERLEY HOWARD of Penny Bank Chambers, Halifax in the County
of York Patent Agent, do hereby declare that I am in possession of an invention
which has been communicated to me by Robert Filecek, Technical Locksmith and
Stephan Schwab, Technical Locksmith both of Nuremberg, in the Empire of
Germany, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in appliances for shaping cutting or
reducing the end of metal rods, by which it is possible to work the rods as they are
cut off a length, whilst hitherto it was necessary to first point the end of a
rod until it was reduced to the thickness desired, in order to be then able to
shape it.
The appliance is formed so that it can be inserted in the head of a drilling frame
or shaping machine or in a lathe, and it is possible to shape or cut any diameter of
rod by the application of corresponding knives and guides.
The accompanying drawings serve to illustrate the shaping appliance.
Fig. 3 is a front view in elevation.
Fig. 1 a longitudinal section parallel to the knife and Fig. 2 is a section diagonal
to the knife, the remaining figs. being plan and underside views, and cross section
on the dotted line of Fig. 3.
The appliance is made of metal and consists of a shaft a with the square piece b
which fits into the drilling frame or the lathe and a head c serving for the reception
of knife d and the necessary grease cups e as well as of the guide or guage f.
Knives d and guide or guage f are of various sizes and may be inserted in any
manner.
The knife d is passed into the slit, provided in the head c and fixed thereon by a
wedge or key h, which latter will render impossible a falling out of the knife whilst
flanges i will centre the knife and secure it against lateral movement.
The guide
or guage serves to guide the rods to be shaped and is fixed by screws k. As
in shaping it is requisite to lubricate the knives for the purpose of protecting them,
grease cups e are provided from which the grease is conducted to the edges of the
knives. The edges of the knives are somewhat farther from each other at the tops
than the points in order to prevent wedging. The cuttings fall through the holes
in the head c when the metal rod enters the hole m.

improvements in Cutters for Cutting and Drains
I, JOHN BRIERLEY HOWARD, of Penny Bank Chambers, Halifax, in the
County of York, Patent Agent, do hereby declare the nature of this invention,
which has been communicated to me by Robert Filecek, Technical Locksmith, and
Stephan Schwab, Technical Locksmith, both of Nuremberg, in the Empire of

page_text: Germany, 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 appliances for shaping, cutting, or
reducing the ends of metal rods, by which it is possible. to work the rods as they
are cut off a length, whilst hitherto it was necessary to first point the end of a
rod until it was reduced to the thickness desired, in order to be then able to
shape it.
The appliance is formed so that it can be inserted in the head of a drilling
frame or shaping machine, or in a lathe, and it is possible to shape or cut any
diameter of rod by the application of corresponding knives and guides.
Such being the nature and object of my said invention, the following is. a
complete description of same, reference being had to the annexed drawings,
in which
Fig. 1 is a sectional elevation of the improved cutter..
Fig. 2 is a longitudinal section of the cutter..
Fig. 3 is an elevation of the cutter.
Fig. 1 is an end or underside view. of Fig. 1.
Fig. 2 is a plan view of Fig. 2.
Fig. 3 is a sectional view of the underside of Fig. 3.
According to this invention, the cutter or tool is made of metal, and consists of
a shaft or stem a with the square or key piece to fit into the head of the drilling
frame or the lathe, and a head c serving for the reception of the cutters d, and the
grease or oil cups e as well as the guiding cap or gauge f. Knives or cutters d and
cap or gauge fare made in various sizes, and may be fixed in the tool as required,'
and by any of the well known methods.
The knife or cutter d is passed into the slot provided in the head c, and fixed
by a wedge h, which latter renders falling out of the knife impossible, while the
flanges or projections i will centre the knife or cutter d and prevent it moving
sideways.
.
The guide or guage f which serves to guide the rods to be shaped, is fixed by
little screws k. As in shaping and cutting it is necessary to lubricate the knives
or cutters, little grease or oil cups e are provided, from which the lubricant is
discharged onto the edges of the knives or cutters. The edges of the knives or
cutters are somewhat further from each other at the tops than at the points,
in order that any "binding" cannot take place. The turnings will fall through
the holes in the head c.
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
The head c in which is inserted the knives or cutters d having flanges or
projections i, wedge h, and guiding cap or guage f, all in combination, as and
for the purpose herein described, and ás illustrated by the annexed drawings.
Dated this 9th day of May 1895.
