Improvements in Grating Machines.
I, AMOS BARR HOSTETTER, a Citizen of the United States, residing at Lancaster,
in the County of Lancaster, and State of Pennsylvania, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described ad ascertained in and by the following state-
ment:-
My invention has relation to a machine for grating cheese, cocoanut, bread,
and the like; and in such connection it relates particularly to the construction
and arrangement of such a grater.
The principal objects of my invention are first, to provide in a grating machine,
a grater disk consisting of a plate of metal having a series of radially arranged
slits or slots, one edge of said slits being provided with inwardly projecting notches
or teeth; second, to provide in such a grater in connection with the disk, a semi-
circular holder at one end of which the grater-disk is adapted to rotate and a
feeding device adapted to traverse the holder to present the substance to be grated
to the teeth of the grater disk; and third, to provide a grating machine with a
movable grater disk, a holder for the substance to be grated, means for supporting
the same and a feeding device adapted to traverse the holder to present the
substance to be grated on the grater disk, said holder provided with front and
back stops for the feeding device to prevent possible contact of the same with the
teeth of said grater-disk during actuation thereof.
My invention stated in general terms, consists of a grating machine con-
structed and arranged in substantially the manner hereinafter described and
claimed.
The nature and scope of my invention will be more fully understood from the
following description taken in connection with the accompanying drawings form-
ing part hereof, in which
Figure 1, is a perspective view of a grating machine embodying main features
of my invention.
Fig. 2, is a front elevational view of the same; and
Fig. 3, is a sectional view on the line -, of the grater disk of Fig. 2.
Referring to the drawings a, represents the standard or base of the machine
preferably provided with lips a, a, adapted to fit the edge of a table or other
suitable support and having a set screw (³, adapted to clamp the standard to its
support. The standard a, supports a semicircular holder b, in which the article
to be grated is adapted to be mounted. This holder by preference is open at both
nds and has in its base a channel or guide-way 61, formed at the rear end portion
in enlargements 62, constituting back-stops, for a purpose to be presently described.
The channel or guide-way b', is adapted to receive and guide the lugs d', d¹, of
the feeding device d. This feeding device d, is provided with an arm or handle d³,
terminating in a semicircular plate or disk ³, and is supported by the handle d³,
in horizontal position and by the disk or plate d³, in vertical position through the
engagement of the lugs d, with the guide-way b₁, of said holder b.
the middle of the disk or plate d³, is provided a recess or offset d', adapted to be
At or about

page_text: brought into engagement with a lug to be presently explained. At the front end
of the holder b, is located a bridge or bracket e, suitably united to said holder
and having an ear e¹, constituting a bearing for a pin or stud e³, on which the
rotary grater disk f, is axially mounted. On the underside of the bridge or
bracket e, is provided a lug e, adapted to be brought into engagement with the
recess or offset d, of the feeding device d, to prevent contact of the said device
with the grater-disk, during the actuation of the same. The grater disk f, consists
of a thin sheet of metal having a series of radially arranged slits or slots f¹, one
edge of each of which slits or slots is provided with a series of notches or teeth fa.
The edges of the slots or slits f', on the front face of the disk are beveled or
countersunk as at f³, and the teeth f, preferably project from the inner face of
the disk on a plane with the bevel f, as clearly illustrated in Fig. 3. The
teeth f, of one slit are preferably in staggered relationship to the teeth f³, of a
succeeding slit, that is, a tooth of one slit is followed by an open space in the
next slit throughout the formation of the disk. By this preferred arrangement,
the surface to be grated is evenly pared or scraped. The disk is preferably
rotated by means of a button or handle k.
The mode of operation of the grating machine hereinbefore described, is as
follows:
The substance, such as cheese, cocoanut or the like, is placed in the holder
and then forced forward in the direction of the inner face of the grater-disk f,
by means of the feeding device d, and the disk, as illustrated, then rotated by
means of the button or handle k, and as the substance is gradually grated the
feeding device is moved forward in the holder b, with the lugs d', d', engaging
in the guide-way 61, until the substance is entirely grated and the recess or offset d',
in the top of the feeding device is brought into engagement with the lug e*, on the
underside of the bridge or bracket e, spanning the holder, and to the ear e', of which the
grater disk f, is journalled or pivoted, when the feeding device may then be
retracted to its normal position that is, to rest against the enlargement 68, of the
guide-way b, or released entirely from the holder b. When the feeding device
has been caused to engage with the lug d, the grater disk may still be rotated,
because the limit of the shifting movement of said device has been reached; and
moreover, without fear of any contact of the same with said disk, which would
tend to destroy the teeth thereof, if the feeding device should so contact, thereby
destroying the same for subsequent grating or similar purposes.
It will be manifestly obvious that as to details of my invention, modifications
may be made in the holder and in the particular arrangement of the disk thereto,
as well as in the feeding device for presenting the substance to be grated to the
disk, without departing from the spirit and scope of my saia invention as illustrated
and as herein before described, and hence
Having now particularly described and ascertained the nature and objects of my
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. In a grating machine, a grater-disk constructed and arranged substantially
as shown and for the purposes described.
2. In a grating machine, a grater disk consisting of a plate having a series of
slots, one edge of each of which is provided with a series of projecting teeth,
substantially as and for the purposes described.
3. In a grating machine, a grater-disk consisting of a thin plate having a
series of radially arranged slots, one edge of each of which is provided with a
series of inwardly projecting teeth, substantially as and for the purposes described.
4. In a grating machine, a grater-disk, consisting of a plate having a series
of slots, the edges of which on the front face are inwardly beveled, a series of
projecting teeth arranged on the rear face along one edge of each slot, said teeth
projecting in the plane of the bevel on the front face of the plate, substantially as
and for the purposes described.

page_text: 5. In a grating machine, a holder of substantially semicircular shape, a movable
grater disk connected with said holder and a feeding device adapted to be slid in
said holder, said feeding device provided with an arm and with a semicircular
disk or plate, substantially as and for the purpose described.
6. In a grating machine, a holder of substantially semicircular shape, a grater-
disk pivoted to said holder and having a lug and offset guide-way, a feeding device
provided with a handle and a semicircular plate or disk provided with a recess,
substantially as and for the purposes described.
7. In a grating machine, a holder of substantially semicircular shape provided
with a bridge or bracket, a grater disk pivotally connected with the bridge or bracket
of said holder, a feeding device provided with a semicircular disk or plate with
a handle and means connected with said holder and bridge for preventing in the
shifting of said feeding device of the same being brought into contact with said
disk, substantially as and for the purposes described.
