AN IMPROVED ROTARY KNIFE CLEANER
Year: 1878

page_text: LETTERS PATENT to Joseph Trecziok, of No. 13, Mount Pleasant, Clerkenwell,
in the County of Middlesex, and Albert Hunter Bower, of No. 6, Vernon St.,
in the said County of Middlesex, for the Invention of "AN IMPROVED ROTARY
KNIFE CLEANER."
Sealed the 28th January 1879, and dated the 29th July 1878.
PROVISIONAL SPECIFICATION left by the said Joseph Trecziok and Albert
Hunter Bower at the Office of the Commissioners of Patents on the 29th July
1878.
JOSEPH TRECZIOK, of No. 13, Mount Pleasant, Clerkenwell, in the County of
Middlesex, and ALBERT HUNTER BOWER, of No. 6, Vernon St., in the said County
of Middlesex. "AN IMPROVED ROTARY KNIFE CLEANER."
An improved stay for the better support of the knives, with ends turned towards
the handles, lined with lather or other material.
Instead of nuts on the shaft to adjust the discs, we have springs in metal or
other material suitable for the purpose inside.
The machines often want cleaning and entail a good deal of trouble, to avoid
which we have an opening at the bottom of drum for a slide or fall, thus making
the machines self-cleaning.

Office on the 29th January 1879.
JOSEPH TRECZIOK, of No. 13, Mount Pleasant, Clerkenwell, in the County of
Middlesex, and ALBERT HUNTER BOWER, of 6, Vernon Street, in the said County of
Middlesex. "AN IMPROVED ROTARY KNIFE CLEANER."
Figure 1 is a front elevation of a knife cleaner constructed according to our
Invention, with one of the standards and one side plate of the outer casing removed
to shew the interior; Figure 2, a plan of same with the upper half of case removed;
Figures 3 and 5, front and side elevations, and Figure 4, a plan of our improved rest
for the knife handles; and Figures 6 and 7, side elevation and sectional plan of our
improved method of setting or adjusting the revolving discs.
Our Invention relates, firstly, to the knife stay. This is shown at A, Figures 3, 4,
and 5. It projects at the top as shown at a, in Figure 2, sufficiently to allow a
good bearing for the knife handle. This part is also hollowed out, as shown in plan,
making the hold on the handle firm. It is also lined with india-rubber, leather, or
other material to prevent injury to the handle, and to avoid slipping by additional
bite.
An additional advantage is in having this portion in one piece with the frame B
attached to the outer casing, and with the tail C projecting within for the lower
part of the knife to bear against, to resist the friction of the revolving discs. This
gives great firmness and steadiness to the knife, and prevents injury by vibration or
twisting so often experienced in ordinary machines.
Our Invention relates, secondly, to improvements in adjusting the revolving discs
on the spindle.
Instead of nuts as ordinarily employed, and which give no security that the
discs will be maintained in the centre of the spindle when they are adjusted by the
ordinary attendant for wear, we do away with the nuts, and instead, employ helical,
volute, or other springs, one on the outside of each disc, the two springs bearing
one on each disc, and pressing them together face to face, the springs being adjusted
on the shaft, and in strength by bearing against adjustable screw nuts. This part
of our Invention is illustrated by Figures 6 and 7 of the accompanying Drawings.
D, D, are the revolving discs; E is a ring fixed to each by screws so as to make
the two as one and to turn together. These rings carry each two hollow arms F,
and attached to them a hollow cup G, and in the centre of the ring the boss fitting
the spindle H, and to which it is keyed so that it may slide thereon, and the two
turn together. The volute spring I is placed in the cup G, and set up to the
required position and strength by the nut J. The same arrangement is employed
at the back of the other disc; and by means of the two adjustable nuts the discs
may be set in the middle of the spindle and pressed together with the required
degree of strength. As the contiguous and rubbing surfaces wear by use, the
springs give out and keep them closely in contact and in the centre of the spindle,
and consequently insures the discs being always properly placed in reference to
openings in the rim through which the knives are introduced between the faces of
the discs.
The hollow arms F are provided at their extremities each with one or more
feeders, which, as the discs revolve, dip into the loose cleaning powder at the bottom
of the casing of the machine, and during the continued revolution pass it down the
said hollow arms F to the centre of the discs where it enters between them, and
again works out by the circumference.
Our Invention relates, thirdly, to the employment of a slide or flap at the bottom
of the casing, to let out the cleaning powder when it is desired to clean the
machine. In other machines this is effected through the opening by which the
powder is introduced, necessitating the tilting up of the machine, which in the
larger ones, they being very heavy, is a process of considerable inconvenience.

page_text: We claim as our Invention to be secured by the herein-before in part recited
Letters Patent,―
Firstly. The improved knife rest, substantially as described and illustrated.
Secondly. The adjustment of the discs by spring and nuts, and the method of
feeding the cleaning material, substantially as described and illustrated.
Thirdly. The employment of the slide or flap for cleaning the machine, substan-
tially as described and illustrated.
In witness whereof, I, the said Joseph Trecziok, on behalf of myself and the
said Albert Hunter Bower, have hereunto set my hand and seal, the
Twenty-ninth day of January, in the year of our Lord One thousand
eight hundred and seventy-nine.
