IMPROVEMENT IN PIPE-CUTTERS
Year: 1884

page_text: I, HERMANN MÜNZING of 1 & 2 Playhouse Yard, Golden Lane in the county of
Middlesex American Merchant do hereby declare the nature of my invention for
AN IMPROVEMENT IN PIPE-CUTTERS to be as follows:-
The invention consists in the construction & application of a detachable sliding
Wheel-block" which is in two pieces & so constructed as to clasp round & slide
up & down the wrought iron bar or body of an ordinary wheel cutting-tool &
operated upon by the handle-rod passing through the lower part of the iron body.
The "Block" contains the cast-steel wheel & pin loosely but securely fitted into
recesses on the inside of the two halves of the Block which are held together by
screws-The wheel projecting outwards is so located as to be directly opposite the
centre of the jaw holding the object to be cut-By this method the following
advantages are gained.
1) The "Block" being detachable allows of being taken to pieces for cleaning or
renewing the wheel or pin.
2) The oil applied to the cutting-wheel is retained in the recesses of the "Block"
& does not run down the rod or tube on to the hands of the operator, nor clog the
screws so as to impair the smooth working of the tool.
3) That the "Block" is so constructed that when using the tool the strain is
being received by it & thrown on to the bar & not on the handle-rod, thus
imparting strength & durability to the whole.

page_text: I, HERMANN MÜNZING of Nos 1 & 2 Playhouse Yard, Golden Lane in the county
of Middlesex, American Merchant, do hereby declare the nature of my invention
for "AN IMPROVEMENT IN PIPE-CUTTERS" and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
The invention consists in the construction & application of a detachable, sliding
"Wheel-block" (a & a 1) fitted to the "Body" (e. b. h) of an ordinary wheel cutting-
tool This "Wheel-block" is in two halves (a & a 1) & so constructed as to clasp
round & slide up & down the wrought-iron bar (b) or "Body," & operated upon by
turning the round "Wooden-handle" (c) fixed to one end of the wrought-iron
"Handle-rod" (d) in the shape of a T. The "Handle-rod" is fitted at the other
end with a nut or head, (f) from which point it is threaded, & screwing through
the lower end of the "Body" (9) is connected to the "Wheel-block" by the nut or
head being received & held loosely in a recess in the "Wheel-block" so as to allow
of a rotary action; by this means the Wheel-block" is moved up & down the
Body as the "Handle-rod" is turned. The Wheel-block' contains the
Cutting-wheel" (1) & "Pin" (i) upon which the "Wheel" revolves loosely,
but securely fitted into recesses on the inside of the two halves of the "Block
which are held together round the "Body" by screws (k & k 1).

The "Cutting-wheel" projecting outwards from the "Block" is so located as to
be directly against the "Jaw" (1) holding the object to be cut.
To perform with the tool, place the pipe, or other round body to bo cut in the
"Jaw" & by screwing the "Handle-rod" to the right the " Cutting-wheel" is
brought into contact with the object to be cut; revolvo the whole tool round &
round, tightening the wheel as the cutting proceeds.
Having now particularly described & ascertained the nature of my said
invention & in what manner the same is to be performed, I declare that what
I claim is:-
1st An improvement in Pipe-cutters resulting from the application of a newly
constructed detachable, sliding "Wheel-block" to the Body of an ordinary Pipe-
cutter as described.
:
2nd The construction of the block as described so that when using the tool the
strain is being thrown by it on to the bar or "Body" & not on the "Handle-rod,"
thus imparting strength & durability to the whole.
