Year: 1884

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & Co, Patent
Agents Southampton Buildings in the County of Middlesex do hereby declare the
nature of my invention for "IMPROVEMENTS IN MACHINES FOR BEVELLING GLASS
to be as follows:-
:-
"
This invention relates to machines for bevelling glass, and comprises a new
arrangement of the wheel turning with a horizontal shaft and capable of roughing,
cutting and polishing the edges of the glasses according to the quality of the wheel
employed, which may be of wood, cast-iron, emery or the like according to the
work to be done.
It also comprises a new arrangement of the frame for receiving the pieces of
glass to be roughened, cut, or polished by the wheel.
The cutting or polishing wheel is mounted upon a horizontal shaft supported by
a pedestal. Upon this shaft is also fixed a stepped speed cone for varying the
velocity of the wheel according to the nature of the latter, its dimensions, and the
work to be performed.
This wheel turns to the right or left and is supplied with water or sand from a
funnel fixed above. The material ground from the surface falls into a cemented
pit.
For supporting and holding the glass a frame is employed the construction of
which is very simple notwithstanding all the requirements. The said frame slides
upon guide bars and consists of two U-shaped irons forming uprights which are
connected by plates some of which are provided with slots so as to enable the
uprights to be adjusted. These slots can be substituted by series of holes very
near each other, by which the same effect is produced.
The glass is supported above and below by strips having grooves, Into these
grooves the edges of the glass to be bevelled are fastened. The lower strips have
lateral projections for carrying the glass. These supporting strips are attached to
the U-shaped bars forming the uprights, and carry bolts with thumb-screws
designed to enter holes formed along the entire length of the said U-shaped bars.
These strips can thus be placed at any height varying according to the height of
the glass to be operated upon. These uprights moreover carry rollers to the axes

page_text: of which are attached hooks connected to a rope wound upon a roller by means of
which it is driven. Two rollers rolling in contact with the guide bars produce an
exceedingly smooth motion.
In order to effect the automatic alternating movements of the glass-carrying
frame, two fixed pulleys and one loose pulley are employed over which two belts
pass, the one crossed and the other open, which cause the rope-driving roller to
turn to the right or to the left.
The rope-driving roller, when turning from right to left, winds up the driving
cord, and the latter pulls the glass upon the glass-carrying frame against the
cutting wheel. A finger fastened by a bolt upon a disengaging bar, at the end of
each travel, permits the automatic return of the frame.
The inclination of the frame is regulated by means of hand-wheels and screws
which carry nuts supporting the said guide-bara
The constant pressure of the glass against the cutting wheel is obtained through
the medium of a spring acted upon by a cam whose position is regulated by a hand-
wheel and pinions.

I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent
Agents, Southampton Buildings, in the County of Middlesex do hereby declare the
nature of my invention for "IMPROVEMENTS IN MACHINES FOR BEVELLING GLASS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to machines for bevelling glass and comprises the
improvements hereinafter described.
The machine constructed according to this invention is characterized 1st by the
arrangement upon a horizontal shaft, of a wheel capable of roughing, cutting or
polishing the edges of the glass according to the nature of the wheel employed,
which may be of wood, cast-iron, emery or the like according to the work to be
done, and 2nd by the arrangement of the frame for carrying easily any kind of
pieces of glass to be roughened, cut or polished by the said wheel.
In the accompanying drawing
Figure 1 is a front view of the improved machine.
Figure 2 is an end view of the same and
Figure 3 shows part of the frame serving for carrying the glass.
The roughing, cutting or polishing wheel A is mounted upon a horizontal shaft
supported by a standard or frame B. Upon this shaft is also fixed a stepped speed
cone a for varying the velocity of the wheel according to the nature of the latter,
its dimensions, and the work to be performed.
This wheel turns to the right or left and is supplied with water and sand from
a funnel, not shown in the drawing, fixed above the said wheel.
The material ground from the surface of the glass together with the water and
the like, fall into a cemented pit F.
For supporting and holding the glass against the wheel A a frame is employed
the construction of which is very simple notwithstanding all the requirements.
The said frame slides upon guide bars J J1 J1 and consists of two U-shaped bars
forming uprights which are connected by a plate E and two other plates G. In
each of the plates G a slot g is formed so as to enable the frame to be adjusted to
suit sheets of glass of various dimensions.
Instead of slots g a series of holes very near each other may be employed by
which the same result is obtained.
The glass is supported at the top and bottom by strips H having grooves in
their inner sides. Into these grooves the edges of the glass to be bevelled are
fastened. The lower strips have lateral projections h for carrying the glass. The
supporting strips H are attached to bars sliding in the channels of the U-shaped
bars V forming the uprights, and are provided with bolts having thumb-nuts K,
the said bolts being designed to enter holes formed along the entire length of the
the said U-shaped bars. The strips H can thus be placed at any height, varying
according to the height of the glass L to be operated upon.
The uprights V each carry a roller C which run upon the guide bar J and
support the glass-carrying frame. To the axis of the rollers C are attached hooks D

page_text: connected to a rope d, by means of which the glass-carrying frame is driven. The
said rope runs around guide pulleys at each end of the frame of the machine and
around the rollers M N (Figure 1). Two guide rollers I rolling in contact with
the guide bar J¹ cause an exceedingly smooth motion of the glass-carrying frame.
In order to effect the automatic alternating movements of the glass-carrying
frame; two fixed pulleys and one loose pulley R are employed, upon which two
belts run, the one being crossed and the other open in a well known manner; the
roller being caused to turn to the right or to the left according as it is driven by
the crossed or open belt.
The roller M when turning from right to left winds up the cord d and draws the
glass-carrying frame towards the wheel A.
A finger O fastened by a bolt upon a bar P (Figure 2) causes the belts to change
pulleys at the end of each reciprocation of the glass-carrying frame, thereby
causing its automatic return.
The inclination of the glass-carrying frame is regulated by means of the hand-
wheels and screws j¹¹¹.
When the machine is in operation the work is accomplished automatically the
workman having only to attend to the discharge of the sand and water.
The constant pressure of the wheel A against the glass is obtained through the
medium of the spring R¹ the pressure of which is regulated by a cam S by means
of the hand-wheel X and pinions Z.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign Correspondent, I declare that what I claim is
First. The machine for bevelling glass constructed substantially as hereinbefore
described and as illustrated in the accompanying drawing.
Second. The arrangement of the roughing, cutting or polishing wheel upon a
horizontal shaft.
Third. The frame carrying the glass to be bevelled, which frame is capable of
assuming any desired inclination, thereby enabling a more or less acute bevel to be
obtained.
Fourth. The employment, with this machine, of wheels of various materials,
forms and dimensions.
