PROVISIONAL SPECIFICATION
Improvements in Surfacing, Glazing, and Polishing Machines.
I, ROBERT SUGDEN, of 2 Dunham Street, Hulme, Manchester, in the County of
Lancashire, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to that class of surfacing, glazing and polishing machines in
which one or more bands suitably rotated and covered with emery or other abrasive
material are employed, and has for its purpose to provide simple and effective means
whereby the object to be operated upon can be readily brought into contact with the
endless band and is acted upon uniformly at any desired angle.
The invention consists in the employment of an adjustable table or support on which
the said endless emery band, by suitable means, is caused to run, in conjunction with
an overhanging adjustable slide or rest against or on which the article to be operated
upon is held or placed.
In carrying out my invention I preferably employ two of the said endless bands of
various grits to rotate side by side on a suitable frame.
One end of the latter is furnished with two adjustable studs and the other end with
a sliding bracket in which is caused to rotate, a short shaft, by means of a pulley fixed
on the middle thereof.
On each end of the said shaft is fixed a pulley arranged to rotate in conjunction
with other pulleys mounted loosely on the said studs, and on which pulleys the endless
emery bands are placed and thereby caused to rotate.
By means of the said adjustable studs and sliding bracket, any desired tension can
be given to the said endless bands jointly or independently of each other.
Underneath the said emery bands I mount a vertically adjustable table or support
on which the said endless emery band is caused to run and over it a rest or slide
capable of vertical, horizontal, or inclined adjustment. The said table serves to give
a firm support to the endless emery band and resist the pressure exerted thereon by
the object under operation, which is held firmly against it by the said slide or rest,
so as to cause the object to be operated upon uniformly at any desired angle, as may
be required.
For holding very thin objects I binge to the said slide or rest an arm, the free end
of which is arranged to hold the object to be operated upon against the said endless
emery band, and to facilitate the object being more or less operated upon, I provide
the said arm with a set screw bearing against the said slide or rest, by means of which
the free end of the said arm, i.e. the object to be operated upon, can be brought
nearer to or further from the endless emery band.
For holding angular objects I pivot to the said slide or rest a radially adjustable
side rest.

Improvements in Surfacing, Glazing, and Polishing Machines.
I, ROBERT SUGDEN, of 2, Dunham Street, Hulme, Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention relates to that class of surfacing, glazing and polishing machines in
which one or more bands, suitably rotated and covered with emery or other abrasive;

page_text: material are employed, and has for its purpose to provide simple and effective means
whereby the object to be operated upon can be readily brought into contact with the
endless band and is acted upon uniformly at any desired angle.
The invention consists in the employment of an adjustable table or support on which
the said endless emery band, by suitable means, is caused to run, in conjunction with
an overhanging adjustable slide or rest, against or on which the article to be operated
upon is held or placed.
And in order that my invention may be more fully understood I have caused to be
appended hereunto two sheets of drawings marked with letters of reference indicating
like parts in the various figures.
Figs. 1 & 4 are end views, Fig. 2 a side view and Fig. 3, sheet I, a plan of a
complete machine. Fig. 5 a side view and Fig. 6 a plan, Figs. 7 & 8, sheet II,
respectively, an end view and side view enlarged, of the middle portion of the
machine.
In carrying out my invention and referring to the figures generally, I preferably
employ two of the said endless bands a of various grits to rotate side by side on a
suitable frame b.
One end of the latter is formed with slots c furnished with two adjustable studs c¹
and the other end with a sliding bracket d in which is caused to rotate a short shaft e,
by means of a pulley f fixed on the middle thereof. The sliding bracket d is made
adjustable on the frame by means of a screw spindle d' furnished with a hand wheel d³
mounted therein and passing through a nut d² formed on the bracket d.
On each end of the shaft e is fixed a pulley g arranged to rotate in conjunction
with other pulleys g¹ mounted loosely on the said studs c', and on which pulleys g, g¹
the endless emery bands a are placed and thereby caused to rotate.
By means of the said adjustable studs c and sliding bracket d, any desired tension
can be given to the said endless bands a jointly or independently of each other.
Underneath the said emery bands a I mount respectively a vertically adjustable
table or support a', on which the said endless emery band a is caused to run and
over it a slide or rest / capable of vertical, horizontal or inclined adjustment.
On each side of the frame b I form a socket or eye b', preferably split, in which is
made vertically adjustable, by means of a bolt i, a round shank On the said
shank, below the emery band a, I mount also vertically adjustable, by means of the
set screw a², the table or support a' aforesaid, over which the endless emery band a
passes. Near each extremity of the said shank is mounted vertically and radially
adjustable by means of a set screw a³ a bed h¹, on which is made horizontally
adjustable by suitable means, the slide or rest h. The said table or support a¹ serves
to give a firm support to the endless emery band a and resist the pressure exerted
thereon by the object under operation, which is held firmly against it by the said
slide or rest h, so as to cause the object to be operated upon uniformly, at any desired
angle as may be required. The said slide or rest h, I preferably form with a
projecting plate 2 formed either in the middle or at one side thereof. In lieu of
employing the said table or support a' and slide or rest in conjunction with the
upper part of the endless emery band a the same may also be applied in a similar
manner as described in conjunction with the lower part of the endless band a as
shown in the drawings.
For holding very thin objects I hinge to the projecting plate h² of the said slide
or rest h, see Figs. 5 & 7, an arm k, the free end of which serves to hold and press
the object to be operated upon against the said endless emery band a ; and to facilitate
the object being more or less operated upon, I provide the said arm & with a set
screw bearing against a projection ³ formed on the projecting plate h² of the said
slide or rest h, by means of which the free end of the said arm k, i.e. the object to be
operated upon, can be brought nearer to, or further away from the endless emery
band a, thus enabling to regulate the amount of surface to be worked off the object
under operation to a nicety and uniformity.
For holding and working angular objects I pivot to the said slide or rest h
a radially adjustable slide, rest or plate l, which can be circularly adjusted on the

page_text: slide or rest by means of the bolt l' running therein, which plate I also form with
a projecting plate 2 against which the article to be operated upon is placed.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is-
In surfacing, glazing and polishing machines.
1st. The general construction and combination of parts constituting my improve-
ments adapted and operating substantially as and for the purpose specified.
2nd. The table a made adjustable on the frame 6 and adapted to support the
endless band a, in conjunction with an overhanging slide or rest h, h', against which
the article to he operated upon is held or placed, substantially as and for the purpose
specified.
3rd. Providing the slide or rest h with an adjustable arm k, adapted to hold and
press the material under operation against the endless band a, substantially as and
for the purpose specified.
4th. Providing the slide or rest
with a radially or circularly adjustable plate or
rest h², adapted to hold and press the article to be operated upon against the endless
band a at a given angle, substantially as set forth.
