1, JAMES WEBSTER, of Fern House, Solihull Lodge, Holly Wood, near Birmingham,
in the County of Warwick, Engineer, do hereby declare the nature of this invention
to be as follows :-
My invention relates to an improved machine for removing the arriss or burr
from slit rods or the like, or the roughnesses from the brazed joints of tubes and
from similar surfaces and edges when the process of their production leaves a line
of projections or roughnesses of no utility.
"
In carrying my invention into effect, I arrange a suitable carrier from which
the material to be operated upon is fed to the machine which is the subject of
this invention.
According to my invention, I arrange, in series, a straightening device (when
necessary), a feeding device, a guiding device, the arriss or burr removing device,
and a coiling device or a despatching device.
The cutters I use are always rotary or milling cutters.
When it is required to operate upon the sides of a rectangular rod, I use a pair
of cutters to smooth the sides of the rod, whose width apart is adjustable by means
of the interposition of washers. The edges are taken off by milling cutters, the
cutting edges of which are in plan an internal U or V, each cutter being by
preference in two halves for convenience in sharpening or replacing. One of these
cutters is below and the other above the rod when four edges are to be operated upon.
When fewer surfaces are to be cut, the number of cutters is diminished accordingly,
and when the number of edges or surfaces to be cut is on one side only of an
axial plane of the rod or tube, suitable rollers are placed opposite the cutters to keep
the rod or tube up in line.
The aforesaid rotary devices are driven by suitable trains of gearing from the
driving pulley of the machine.

The drawings illustrate the application of my invention to the dressing of slit
rods of a rectangular cross section, although I wish it to be distinctly understood
that the invention is easily applicable to dressing lengths of metal of any cross
section, either tubular or solid, by simply modifying the operative parts of the
invention as the nature of the work require of it may demand.
A, A are standards supporting B, the bed of the driving gear and C, the shears
upon which are carried the operative devices of the invention.
The driving gear consists of the first motion shaft D fitted with the usual fast
and loose pulleys (of a proper diameter for driving the cutters at the required speed),
a spur wheel d, pinion d¹, and second shaft d.
The feeding gear consists of a pair of drums e, e rotated in a suitable frame E
which is capable of being moved backwards and forwards upon the shears C, and
is furnished with a proper fixing device after the manner of a slide rest. The axes
of the rollers carry equal pinions e¹, e¹. The top roller is raised by spiral springs e³, et
between the bushes, and depressed by a set screw acting upon a bar spring bearing

page_text: evenly upon the top bushes. A table et projects from the left hand side of the
frame E, and upon it are aligned straightening pins e and a hollow guide e
between and through which the slit rod e' is led in a right line to the cutters.
The cutters are three in number and are carried upon the respective outer ends
of three spindles f,f,f, rotatable in a frame F stationary upon the shears C. The
spindle is a linear continuation of the shaft &, and carries a pinion . The
two spindles, likewise respectively carry pinions f, f. The last mentioned
three pinions and the two, e¹, e¹ of the feeding gear are of the same diameter and
pitch, so that when the lower pinion of the feeding gear engages with the pinion ƒ³,
the whole five move at the same speed but in alternately opposite directions.
The bearings of the three spindles f, f, fare capable of vertical adjustment in
the standards of the frame F by means of set screws f*, and there are also provided
three adjustable guides for the purpose of keeping the rod in a truly horizontal
line, as it passes through the cutters, in spite of the strains to which their action
subjects it.
The first cutter, G, dresses the sides of the rod; the second one H operates
on the top angles, and the third, H', on the bottom angles of the rod.
The first one is illustrated in detail in Figs. 4, 5, and 6.
The end of the spindle is turned down, or shouldered, and screwed to receive
a collar against which bears a hollow half-cutter g¹. The distance between this
half-cutter and the second one g² is made up with washers g³. A second collar 9₁—a
duplicate of the former-holds the second half-cutter up to the packing washers.
A nut on the nose of the spindle completes the equipment of the spindle end. The
two half-cutters can therefore by means of the collars and washers be, and are,
adjusted upon the spindle end so that the space between them is truly aligned
with the tunnel of the hollow guide e.
The second and third cutters H, H¹ are of simpler construction, each consisting
of two half-cutters h, h held by nuts up against shoulders on the ends of their
respective spindles, and duly aligned with the guide e.
The diameter and circumferential velocity common to all three of the cutters are
adjusted according to the nature of the metal to be operated on.
The taking-off gear consists of a pair of drums i, i on the outer ends of two
spindles rotatable in a frame I stationary upon the shears C. Their bearings
are adjustable vertically by means of screws actuated by a hand wheel and
equal gears. The spindles i, receive their motion from a spur wheel it on
the upper spindle and which is driven by one of equal diameter therewith
on the shaft d'. A pair of equal spur pinions, on said spindles communicates
motion from the upper spindle to the lower one.
The lower of these spindles is continued through its drum to the front of the
machine, where it carries a reel K around which the end of the dressed rod is taken ;
the motion of the drum reeling the rod as the latter comes away from the drums.
It is self evident that the several contours of the guide e, the feed drums e, e, the
cutters, the guides and the taking-off drums may be modified to adapt them
to that of the length to be operated on.
The number of cutters, as well as of
the guides may also be modified for a like reason. Also, if the length is to
be delivered from the machine straight, the reel K will not be used.
L is a strap shifter of any convenient type fixed within reach of the attendant when
standing at his post in front of the machine.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. The combination with a train of equal spur pinions, of a movable frame carrying
a hollow guide and a pair of feed drums adjustable relatively to each other therein,
a stationary frame carrying one or a series of spindles each spindle carrying a cutter
and vertically adjustable therein and an adjustable guide or guides; substantially
as described with reference to the accompanying Figs. 1, 2, and 3.
2. The combination of a pair of feed drums, a series of cutters, and a pair of

page_text: taking-off drums, with a train of gearing operating the whole at a common
circumferential velocity; substantially as described with reference to the accompanying
drawings.
3. The combination of a hollow guide with a pair of feed drums, a series of cutters,
a set of adjustable guides and a pair of taking-off drums, the drums and cutters all
being rotated at the same circumferential velocity; substantially as and for the
purpose described with reference to the accompanying drawings.
4. The combination of a shouldered spindle end, a pair of collars, a pair of hollow
half-cutters between them, and an adjustable packing between the said half-cutters,
with a rotary feeding device actuated by the same train of gears from which the
rotary motion of the cutter is taken; substantially as described with reference
to the accompanying Figs. 4 to 6.
