in the Republic of France, Engineer and Patent Agent, for an Invention
of "A METAL, DRESSING MACHINE HAVING AN OSCILLATING CUTTING TOOL."
A communication by Henri Pieper, of 33, Rue Bassenge, Liège, in the
Kingdom of Belgium.
COMPLETE SPECIFICATION filed by the said Raphael Hunter Brandon at
the Office of the Commissioners of Patents on the 28th October 1881.
RAPHAEL HUNTER BRANDON, of No. 1, Rue Laffitte, Paris, in the Republic of France,
Engineer and Patent Agent. "A METAL DRESSING MACHINE HAVING AN
OSCILLATING CUTTING TOOL." A communication by Henri Pieper, of 33, Rue
Bassenge, Liège, in the Kingdom of Belguim.
In this new metal dressing machine the cutting tool or cutter has only an
oscillating motion.
The machine is set in motion by a belt or otherwise, and the rotary motion of
the same is converted into an oscillating motion which is imparted to the cutter.
The object of this machine is to bore or cut holes, either rectangular or square,
with straight-sides and edges, or convex or concave.
Upon the driving pulley P is fixed a disc Q having a groove R in which works
a slide S. The slide S is connected by means of a rod W with a toothed
segment T, the axis V of which is secured to the frame of the machine. The
segment T actuates a pinion Z keyed on the shaft A of the cutter B. The
cutter B is secured on to the crank-shaped prolongation of the shaft A in such
manner that the centre of the cutter is in a line with the shaft A. The driving
pulley P being actuated, the notion is imparted to the toothed segment T, which
motion is converted into an oscillating motion by means of the slide S which
works in the groove R. The oscillations of the segment are transmitted by the
teeth of the same to the pinion Z, and thereby also to the shaft A and cutter B ;
a table D having an appropriate clamping device C for the object to be cut is

page_text: placed in a movable manner by means of the part E upon the frame below the
cutter B, and is made to be raised and lowered according to the requirements.
The clamping device C has two motions E, E', at right angles to each other,
allowing the object to be cut to travel in a horizontal plane.
The tool works as follows:-The object or metal part to be cut having
previously a hole bored in it, is secured in the clamping device C, which as well as
D is placed in the proper position. Motion is then imparted to the machine, and
the part is made to move forward by means of E¹, E³, E³, against the cutter B
oscillating on its centre M.
B1, B2, B3, show a few cutters on a multiple scale which can be used in this
machine. The teeth of the cutters should all be at the same distance from the
centre M of the cutter.
Having thus described the nature of the Invention, as well as the best means
known to me for carrying the same into practice, I claim,-
In cutting machines, the transformation of the rotary motion into an oscillating
motion transmitted to the cutter.
In witness whereof, I, the said Raphael Hunter Brandon, have hereunto set
- my hand and seal, this Twenty seventh day of October, One thousand
eight hundred and eighty one.
