"IMPROVEMENTS IN MEANS OR APPARATUS FOR USE IN PACKING
AND PRESERVING, POLISHING OR ABRASIVE PLATES OR DISCS IN PILES OR SERIES
DURING TRANSPORT OR OTHERWISE" (a communication to me from abroad by
Luther D. Shepard, of Boston, in the County of Suffolk in the State of
Massachusetts one of the United States of America Dentist)
This invention relates to means for packing and preserving in good condition
abrasive discs such as employed by dentists for cutting and polishing the teeth or
metal fillings therein, and also in means for holding assorted discs so that the
proper one can be selected and used
The invention consists in a package of flexible discs for dental purposes adapted
for shipment, the discs being held together between rigid plates or followers
pressed against the ends of the pile as will be described.
The invention also consists in an apparatus for holding and preserving assorted
piles of abrasive discs for dental purposes.
In the practice of dentistry small thin discs of paper covered with glass, emery,
or equivalent cutting material are employed to enter the space between adjacent
teeth and polish or abrade the same to remove more or less of the substance of the

teeth as may be desired, the said wheels when in use being connected at their
open centres with the mandril of a dental engine or lathe.
These discs are in many cases treated with shell-lac or other similar material to
give them the requisite stiffness.
Discs treated in this manner if left to themselves will become warped or bent
and consequently will not run true when rotated in the lathe or engine. Such
warping is obviated by the holder forming the subject of the present invention by
means of which the discs are retained perfectly flat and occupy the least possible
space, they forming a package that may be conveniently handled or packed for
shipment
The package or holder consists essentially of two rigid plates or followers prefer-
ably of the same shape and a trifle larger than the discs which are to be packed
between them combined with springs tending to draw the said plates towards one
another to compress the discs packed between them and thus retain them-perfectly
flat, and a central spindle to keep the said discs in co-incidence with one another.
The plates are provided with cars or lugs to receive the springs which extend
along the sides of the cylindrical pile of discs and the spindle or wire is run
through the central openings of the discs by which they are to be subsequently
applied to the mandril of the engine.
The abrasive discs are of various sizes, thickness and fineness and it frequently
happens that a dentist wants instantly to use a disc of a certain number or grade
and to enable the discs to be held in piles assorted according to number or sizo
and to be quickly taken from its pile, a holder is employed containing a series of
upright guides each to receive and direct, the discs of a given grade or size which
may be transferred thereto from the shipping package before mentioned and a
spring operated presser is provided to keep the discs down on the guides and the
dises of each pile closely together, the said presser being so held as to readily rock
or tip to make the presser self adapting or conformable to the face of the upper-
most disc of the pile of discs, so that the discs are subjected to equal pressure one
against the other at all points whereby it is impossible for the discs to warp or get
out of trueth
With such a holder a disc of any desired size or grade may be readily and
quickly taken from its pile and each disc will be found straight and true since the
pressure on the sides of the same is at all times uniform as it rests on the pile.

"IMPROVEMENTS IN MEANS OR APPARATUS, FOR USE IN PACKING
AND PRESERVING, POLISHING, OR ABRASIVE, PLATES, OR DISCS, IN PILES, OR SERIES,
DURING TRANSPORT OR OTHERWISE (A communication to me from abroad by

This invention relates to means for packing and preserving in good condition
abrasive discs, such as employed by Dentists for cutting and polishing the teeth or
metal fillings therein, and also in means for holding assorted discs so that the
proper one can be selected and used.
The invention consists in a package of flexible discs for dental purposes adapted'
for shipment, the discs being held together between rigid plates or followers pressed
ngainst the ends of the pile as will be described
The invention also consists in an apparatus for holding and preserving assorted
piles of abrasive discs for dental purposes
In the practice of dentistry small thin discs of paper covered with glass
emery or equivalent cutting material are employed to enter the space between.
adjacent teeth and polish or abrado the same to remove more or less of the
substance of the teeth as may be desired the said wheels when in uso being
connected at their open centres with the mandril of a dental engine or lathe.
These discs, are in many cases treated with shell-lac or other similar material to'
give them the requisite stiffness.
Discs treated in this manner if left to themselves will become warped or bent
and consequently will not run true when rotated in the lathe or engine. Such
warping is obviated by the holder forming the subject of the present invention, by
means of which the discs are retained perfectly flat and occupy the least possible
space, they forming a package that may be conveniently handled or packed for
shipment.
The package or holder consists essentially of two rigid plates or followers
preferably of the same shape and a trifle larger than the discs which are to be
packed between them combined with springs tending to draw the said plates
towards one another to compress the discs packed between them and thus retain
them perfectly flut, and a central spindle to keep the said discs in coincidence with
one another:
The plates are provided with cars or lugs to receive the springs which extend
along the sides of the cylindrical pile of discs and the spindle or wire is run through
the central openings of the discs by which they are to be subsequently applied to
the mandril of the engine
"
The abrasive discs are of various sizes, thickness and fineness, and it frequently
happens that a dentist wants instantly to use a disc of a certain number or grado
and to enable the discs to be held in piles assorted according to number or size
and to be quickly taken from its pile, a holder is employed containing a series of
upright guides each to receive and direct the discs of a given grade or size which
may be transferred thereto froin the shipping package before mentioned, and a
spring operated presser is provided to keep the discs down on the guides and the:
discs of each pile closely together, the said presser being so held as to readily rock
or tip to make the presser self adapting or conformable to the face of the uppermost
:

page_text: disc of the pile of discs, so that the discs are subjected to equal prossure one
against the other at all points whereby it is impossible for the discs to warp or get
out of truth.
Figuro 1 is a plan view and
Figure 2 a front elevation of a series of discs packed in a holder or package for
shipment in accordance with this invention.
Figure 3. is a front view of a disc holder for the graded or assorted discs
embodying this invention, it however showing but two piles of discs whereas in
practice the holder will contain from twelve to twenty four piles arranged in two or
more banks
Figure 4, is a side elevation of Figure 3.
Figure 5 a plan view of Figure 3, and
Figure 6, one of the discs.
The holder or package for shipment of the discs shown in Figures 1. and 2
consists of two rigid plates a, b, preferably a trifle larger in diameter than the
discs c, of a given size or grade to be packed and held between them
. The said plates a, b, are provided with ears or hooks d to receive the ends of
springs e shown in this instance as rubber bands by which the said plates are
drawn towards one another and compress the discs c between them preventing.
the said discs from warping and keeping them perfectly flat until they are
removed and transferred to the other holder shown in Figures 3. 4, and 5, or are
put in use.
The discs c are provided with the usual central opening for attaching them to
the mandril of the lathe or engine by which they are to be operated, and when.
the said dises are placed in coincidence with one another in a cylindrical pile the
said openings from a central tubular passage through the said pile, and in order to
keep the discs in coincidence with one another and prevent any of them from_being_
pushed laterally out from between the holding plates a. b. the package of discs is
provided with a central spindle or wire f passed through the central openings of the
discs and through oorresponding openings 2 in the plates a. b.
The said wire f is bent at one end as shown to engage the adjacent plate a and
the other and which projects through the central passage of the package may be
bent down upon the other plate to retain the wire in place until the discs are to be
used when it will be bent back into line with the axis of the package to enable
the discs to be removed.
When in this condition, as shown in the drawings the wire will be retained in
place or prevented from becoming disengaged from the package by its friction
therein, the said wire being substantially as large in diameter as the holes in the
discs.
The discs when held as herein described form a convenient package for
shipment or to be laid away or stored until the discs are desired for use when
they may be removed from the package and placed each size or grade by itself
on the guides h h of the holder shewn in Figures 3 to 5 thus forming piles A. B.
of discs of different assorted size or grade arranged side by side.
Upon a suitable part of the frame work are placed a series of arms with
springs denominated presser carriers they being herein shown as composed of
wire secured in position by screws . These spring arms which serve as carriers
for the pressers are extended beyond the guides and piles A. B of discs so that
their free ends may be readily engaged by the forefinger and lifted while the other
fingers turn back under the presser to pick up a disc-The spring arms or carriers
have eyes or bearing portions 20, to receive lugs or journals 3 of the pressers m
made as metal discs having central holes to fit over the guides, the said pressers
being thus held so that they are free to turn in the bearings 20 to enable the
pressers to conform to and closely press against the topmost disc no matter what
is the height of the pile of discs.
The coil in the wire serves to exert the pressure required
With a holder such as shown a disc of any desired size or grade may be readily

page_text: and quickly taken from its pile and each disc will be found straight and truo
since the pressure on the sides of the same is at all times uniform as it rests on
the pile.
Having thus described the said invention and means I adopt in carrying the
same into practical effect I would have it understood that what I claim, is
1. A Package of flexible abrasive discs for dental purposes adapted for shipment
the discs being held together between rigid plates or followers pressed against the
ends of the pile substantially as described
2. An apparatus operating substantially as described for holding and preserving
a series of assorted piles of abrasive discs for dental purposes.
In witness whereof I the said Alfred George Brookes have hereunto set my hand
and seal this twenty second day of January in the year of our Lord One thousand
eight hundred and eighty four.
ALFRED GEORGE BROOKES (L.S.)
