COMPLETE SPECIFICATION.
Improvements in Riming Tools.
We, NATHANIEL ELSWARD SMITH of 24 Magnolia Avenue, Jersey City in the
County of Hudson and State of New Jersey United States of America, Real
Estate Agent, and JOHN RHODERIC MCPHERSON of Taylor's Hotel, Jersey City,
in the County of Hudson and State of New Jersey United States of America, a
Senator of the United States, 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 :-
The object of the invention is to produce a simple, cheap, light, and easily-
manipulated rimer, capable of ready attachment and detachment, whereby the ends
of pipes particularly those of lead pipes, may be given a flaring and enlarged form
as shown in the Specification of British Patent No. 12823 of 1891.
In the accompanying drawings,
Figure 1 is a perspective view of a rimer constructed in accordance with our
invention, the same being shewn in an operative position, and
Figure 2 is a corresponding view, the holder or clamp being shown open and the
removable sections whereby the size of the opening in the clamp or holder is
regulated, being shown removable.
In these drawings A represents the frame of the device which has formed with or
attached to one end, the lower jaw A of the holder or clamp and is provided at
the other end with a socket 12 in which the tool is held, and is free to slide.
Hinged to the lower jaw A2 of the holder or clamp is the upper jaw A³ this
jaw A being provided at the end opposite to that at which it is hinged with an
indentation a designed to receive the screw-rod C, which, when the screw C
occupies the opening a in the upper jaw, is turned upon the upper surface of the
jaw A and serves to retain the pipe which is held in the opening u³ formed by
indentations in the meeting faces of the jaws, firmly in position to be operated
upon.
The indentations in the jaws are of a size to receive the largest pipe commonly
operated upon, and to allow the use of the device on smaller pipes we provide the
sections D of different thicknesses. These are to be applied in the indentations to
render the opening smaller and for this purpose are provided with pins or pro-
jections entering holes as in the indentations of the jaws..
E represents the riming tool which is provided with cutting edges e of such form
as to rime out, and enlarge the end of the pipe worked upon the inner edges of the
jaws A and A being provided with the indentations a' permitting such enlargement
of the pipe while being held by the clamp.
The shank E of the riming tool is threaded for nearly its entire length and is
provided with a square end 3 for the reception of a handle whereby the tool is
turned.
Between the portion B of the frame and the riming tool is placed the nut e³
screw-threaded on its interior and engaging the screw-thread of the shank of the
tool.
In the use of the tool the pipe to be worked upon is placed between the clamping
edges and the same are then firmly locked together. When this is done the tool is
then slid from its socket until the cutting faces rest upon the end of the pipe, and
then the nut is turned until it bears against the inner face of the socket. When
the parts are in this position turning of the shank of the tool to the right will
result in cutting the end of the pipe, and giving the desired form thereto, and will
also result in the automatic forward feeding of the tool as the cutting edges enter
the pipe.

page_text: Should it advance too rapidly, it is only necessary to turn the nut forward to a
position away from the socket when pressure which the tool exerts against the end
of the pipe may be regulated by hand.
may
The tool may ordinarily be held in the hand or in a vice but if necessary it
be provided on its lower face with a dovetailed groove designed to receive a dove-
tail attached to a board or plate, whereby it will be held firmly in position for
use.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is--
1. A. rimer consisting essentially of a clamp or holder for retaining the pipe-ends,
a riming tool mounted and free to slide in a frame to which the clamp or holder is
attached the rimer being placed in a line with the clamp or holder and a nut placed
upon the shank of the tool and bearing against the portion in which the tool slides
substantially as described.
2. A rimer consisting of a clamp or holder composed of two hinged portions
provided with a central opening for the reception of the pipe, a locking device
whereby the parts of the clamp or holder may be speedily joined together or
released from each other a riming tool having a screw-threaded shank arranged in
line with the pipe to be worked upon, a nut placed on the shank of the tool and
bearing against an abutment substantially as described.
3. A rimer consisting of a clamp or holder composed of hinged parts provided
with a locking device, and with a central opening for the reception of the pipe,
removable sections provided with projections designed to be placed in the opening
in the clamp or holder and to regulate the size of the opening for the reception of
the pipe and a riming tool arranged in line with the opening in the clamp or holder
and provided with a screw-threaded shank passing through a nut whereby by
turning the tool the same will be advanced substantially as described.
