Improvements in connection with Stocks and Dies.
WILLIAM CARTY 4 Rhos Cottages Gyffin Rond Conway N. Wales Plumber
do hereby declare the nature of this invention to be as follows:-
After cutting a gas or other pipe it is now necessary to file the end of the pipe
before using the solid screwing dies, & to obviate such filing, this improvement is
for the purpose of converting the present bed of the screwing die into a female
rimer, which will be made to expand and allow the solid die to cut as at present.
Dated this 12th day of October 1895.
I, WILLIAM CARTY of 4 Rhos Cottages, Gyflin Road Conway North Wales,
Plumber, 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 :-
After cutting a gas or other pipe it is now necessary to file the end of the pipe
before using the solid screwing dies and to obviate such filing this improvement is
for the purpose of converting the present bed of the screwing die into a female
rimer which is to be made to expand and allow the solid die to cut as at present.
In order that my invention may be fully understood will now refer to the
annexed drawings in which :-
Figure 1. is a side elevation of my invention.
Figure 2. longitudinal section.
Figure 3. plan view of rimer in position on stock.
Figure 4. elevation of two halfs of rimer.
Referring to Figures 1, 2 & 3. a is the pipe, band bare the two parts or sections
forming the rimer which carry the cutters c which are secured in dovetail grooves
by means of the screws d (Figure 2) e is a ring which holds the two sections
together when in use, and the whole is secured in the stock e' by the nuts or
screws, the flanges g & g' being provided with simicircular indentations and
for the passage of the stem of the bolts or screws, the screw-cutting dies being
inserted in the stock in the ordinary manner. In Figure 4 are pins upon the
section b which engage in holes or apertures in the section b. k, kare springs
which are attached to the section b which engage or euter slots or recesses 1, 1, in
the section ¹.
It will be seen that when the device is operated upon the end of the pipe a any
burr will be removed and the surface of the pipe prepared for being screwed.
By removing the ring e the two sections can be separated and the end of the pipe
can then be screw threaded in the ordinary way. It will be seen that the rimer
may be formed in two or more sections.

page_text: Having now particularly described and ascertained the unture of my aid inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination construction and arrangement of a rimer for use with a
stock for preparing pipes for the cutting of screw threads upon same.
2. In rimers, in combination, two or more sections or parts carrying cutters in
grooves, secured therein by means of screws or the like, said sections having flanges
which have indentations and engage in a recess in the stock being secured therein
by bolts screws or the like, a ring or sheath which encircles said sections when in
operation upon a pipe, said sections being provided with springs and corresponding
recesses for the reception of same; and having also pius engaging in corresponding
apertures or holes for the purpose of maintaining the sections in their relative
positions when encircled by the ring or sheath.
