PROVISIONAL SPECIFICATION.
Improvements in Machinery for Rolling Metal Forms.
I, CHARLES FREDERICK BROOKER, of Ansonia, in the State of Connecticut,
United States of America, do hereby declare the nature of this invention
to be as follows:-
My invention relates to a machine constructed to roll metal forms, and con-
sists essentially of a pair of facing rolls, a pair of edging rolls located in front
of the facing rolls, a guide situated between the edging rolls and the facing
rolls, and a guide situated behind the facing rolls.
My invention also relates to various details of construction of the machine
which I will now describe.
The object of my invention is more particularly a machine by means of
which bodies of copper may be given a definite shape by rolling instead of draw-
ing, as has heretofore been the practice.
In the drawings similar numerals indicate like parts in the several figures.
Fig. 1 is a front view of the machine with the small directing rolls shown
in Fig. 2 removed.
Fig. 2 is an end view and vertical section through the supporting bracket
and one of the adjusting screws for the housings which carry the edging rolls,
and also shows the main frame for the facing rolls, broken away at the bottom,
in order to illustrate the position of the adjusting screws for the lower of the
facing rolls.
Fig. 3 is a front view of the facing rolls with their supporting frame, with
one side of the supporting frame and also the ball bearings and driving shafts
shown in vertical section.
Fig. 4 is a side view of the guides in front and behind the facing rolls, with
the facing rolls in vertical section.
Fig.
is a front view of the guide located between the edging rolls and the
facing rolls.
In the drawings, 5 indicates the supporting frame for the facing rolls. This
frame consists of the base 6 and uprights 7. The uprights 7 are slotted verti-
cally, as shown at 8, Fig. 2; and in these slots are located the vertically mov-
able ball bearings 9 and 10. The bearings 9, on opposite sides of the machine,
are carried by the rods 11 and yoke 12 supported on, and vertically movable,
by means of the screws 13, which have their bearing in the top portions of the
uprights 7. The bearings 10, on opposite sides of the machine, are supported
and adjustable by means of the screws 14, which have their bearings in the
lower portion of the machine.
Located on and connected to the ends of the screws 13 and 14 are the concave
bearings 15, and carried in these bearings are the plano-concave bearings 16.
These bearings conform, on their plain surface, to the contracted portion of
the facing rolls 18.
In the drawings, Figs. 1 and 3, the facing rolls are angularly disposed as

page_text: regards each other; for instance, in the position they would be arranged to
roll a V-shaped copper form.
By means of the adjusting screws 13 and 14 the facing rolls may be arranged
with their axes parallel, or the angular inclination of the axes altered at will.
The ends 19 of the rolls 18 are hexagonal in shape and are connected through
couplings 20, also hexagonal on their interior, to the hexagonal driving shafts 21.
Located on the outer sides of the uprights 7 are the thrust-plates 22. These
plates prevent the lateral displacement of the vertically adjustable bearings 15,
but do not interfere with the rolling of the ball-bearings 16.
Located in front of the machine, and formed as a part of the machine by
asting, or connected thereto in any suitable manner, as by means of bolts,
is the bracket support 23. The top of this support is cut away to form the dove-
tail longitudinal slot 24 and the concave longitudinal opening 25. Mounted
on the top of the bracket support 23 are the housings 26 for the edging rolls.
The base of the housings have a dove-tail shaped projection 27, which fits into
the dove-tail slot 24 of the bracket 23, and they are also provided with depend-
ing portions 28, screw-threaded on their interior, and in which are located the
screw-threaded shafts 29, 29ª. These shafts have the same vertical axes and
act respectively on the housings to which they are connected to give thein
longitudinal motion along the bracket support 23.
The upper portion of the housings 26 are formed as bearings 30; and located
and supported in these bearings is the slotted shaft 31. Located upon this
shaft are the bevel gears 32. These gears are loose on the shaft and therefore
capable of longitudinal motion on the shaft and receive motion from the shaft
through the instrumentality of the keys 33. The gears 32 mesh with the
gears 34, which are carried in the bearings 35.
Connected to the gears 34 are the short hexagonal shafts 36. Mounted on
the shafts 37, which have their bearings in the dove-tail portion 27 of the
housings 26 and which are hexagonal on their upper end, are the edging rolls 38.
These rolls may be given any surface contour desired. That shown in the
drawings has two diameters, the greater diameter being at the bottom.
Mounted on the shaft 36 are the slotted clutches 39, having hexagonal open-
ings which correspond to the shape of the shafts 36 and 37. Vertical move-
ment is imparted to this clutch by means of the lever 40, which is pivoted
at 41 to the uprights 7. The inner end of this lever is forked as at 42 and
partially surrounds the clutch, to which it is loosely connected through pins 43,
which take in the slot 44 of the clutch 39. By means of the levers 40 the
edging rolls 38 can be thrown into and out of operation as desired.
45, 46, 47 and 48 represent gears intermediate of one of the main driving
shafts 21 and the shaft 31. The arrangement of these gears is such that the
speed of the facing rolls and edging rolls will be the same.
Mounted between the facing rolls and the edging rolls is the front guide 50,
and located behind the facing rolls is the back guide 51. These guides con-
sist of pairs of opposing guide-hoxes 52. The shape given to these boxes is
best shown in Fig. 5. That is, the boxes project at top and bottom toward
each other and have a cavity at or about their centres. The object of giving
them this shape is to cause them to direct the material passing through the
machine in a straight line. I do not limit myself to the particular shape given
to the faces of these guide-boxes as it may be varied without departing from
the intent of my invention.
The guide-boxes 52 are mounted upon the horizontal plate 53, which is sup-
ported by the vertical side frames 54 secured to the uprights of the machine.
The guide-boxes 52 are longitudinally adjustable upon the supporting plate 53,
and to or from the facing rolls 18, by means of the screws 55, and they are
also adjustable relatively to each other, i.e., transversely of the plate 53 by
means of the screws 56, so that the distance between them may be altered.
The side boxes 52 of the guide 50 project between the rolls 18 but are not

page_text: carried past the vertical axis of the rolls; whereas the side boxes of the guide 51
project past the vertical axis. This is the only difference of construction
between the guides 50 and 51 and this difference in construction is for the
purpose of preventing a strip when passing the rolls from following the curva-
ture of the rolls and turning upward. The shape of the side boxes projecting
through the rolls prevent this.
Located in front of the guide rolls 38, and supported upon the bracket 23,
are the vertically directing rolls 57 and horizontally adjustable directing rolls 58,
shown in Fig. 2.
The operation of my device is as follows:-The strip to be rolled and shaped
is introduced through the directing rolls 57 and 58 until it is caught by the
edging rolls 38, the edging rolls direct it into the guide 50, thence it passes
through the facing rolls 18 and finally out through the rear guide 51.
It will be observed that the path of movement of the strip through the
machine from the time it enters the directing rolls 38 is along a single hori-
zontal plane.
The result of the rolling is a copper body of definite and predetermined
shape, straight and with finished edges.
As has been explained the contour of the body may be changed by altering
the relation of the axes of the facing rolls and contour of the edging rolls;
and bodies of different width may also be obtained by changing the distance
between the pairs of facing rolls and the pairs of edging rolls, or one rela-
tively to the other.
I do not wish to limit myself to the precise details of construction set forth
in this specification, as many changes may be made without departing from
the intent of my invention.
I wish to have it understood that I consider myself to be the first to employ
an organised machine for rolling copper forms wherein two sets of rolls acting
conjointly give shape to the body passing through them.

Improvements in Machinery for Rolling Metal Forms.
I, CHARLES FREDERICK BROOKER, of Ansonia, in the State of Connecticut,
United States of America, 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 a machine constructed to roll metal forms, and con-
sists essentially of a pair of facing rolls, a pair of edging rolls located in front
of the facing rolls, a guide situated between the edging rolls and the facing
rolls, and a guide situated behind the facing rolls.
My invention also relates to various details of construction of the machine
which will first be described and then pointed out in the claims.
The object of my invention is more particularly a machine by means of
which bodies of copper may be given definite shape by rolling instead of draw-
ing, as has heretofore been the practice.
In the drawings filed with my Provisional Specification similar numerals
indicate like parts in the several figures.

page_text: Fig. 1 is a front view of the machine with the small directing rolls shown'
in Fig. 2 removed.
Fig. 2 is an end view and vertical section through the supporting bracket
and one of the adjusting screws for the housings which carry the edging rolls,
and also shows the main frame for the facing rolls, broken away at the bottom,
in order to illustrate the position of the adjusting screws for the lower of the
facing rolls.
Fig. 3 is a front view of the facing rolls with their supporting frame, with
one side of the supporting frame and also the ball bearings and driving shafts
shown in vertical section.
Fig. 4 is a side view of the guides in front and behind the facing rolls, with
the facing rolls in vertical section.
Fig. 5 is a front view of the guide located between the edging rolls and the
facing rolls.
In the drawings, 5 indicates the supporting frame for the facing rolls. This
frame consists of the base 6, and uprights 7. The uprights 7 are slotted verti-
cally, as shown at S, Fig. 2; and in these slots are located the vertically mov-
able ball bearings 9 and 10. The bearings 9, on opposite sides of the machine,
are carried by the rods 11 and yoke 12, supported on, and vertically movable,
by means of the screws 13, which have their bearing in the top portions of the
uprights 7. The bearings 10, on opposite sides of the machine, are supported
and adjustable by means of the screws 14 which have their bearings in the
lower portion of the machine.
Located on and connected to the ends of the screws 13 and 14 are the concave
bearings 15, and carried in these bearings are the plano-concave bearings 16.
These bearings conform, on their plain surface, to the contracted portion 17 of
the facing rolls 18.
In the drawings, Figs. 1 and 3, the facing rolls are angularly disposed as
regards each other; for instance, in the position they would be arranged to
roll a V-shaped copper form.
By means of the adjusting screws 13 and 14 the facing rolls may be arranged
with their axes parallel, or the angular inclination of the axes altered at will.
The ends 19 of the rolls 18 are hexagonal in shape and are connected through
couplings 20, also hexagonal on their interior, to the hexagonal driving shafts 21.
Located on the outer sides of the uprights 7 are the thrust-plates 22. These
plates prevent the lateral displacement of the vertically adjustable bearings 15,
but do not interfere with the rolling of the ball-bearings 16.
Located in front of the machine, and formed as a part of the machine by
casting, or connected thereto in. any suitable manner, as by means of bolts,
is the bracket support 23. The top of this support is cut away to form the dove-
tail longitudinal slot 24 and the concave longitudinal opening 25. Mounted
on the top of the bracket support 23 are the housings 26 for the edging rolls.
The base of the housings has a dove-tail shaped projection 27, which fits into
the dove-tail slot 24 of the bracket 23, and they are also provided with depend-
ing portions 28, screw-threaded on their interior, and in which are located the
screw-threaded shafts 29 29ª. These shafts have. the same horizontal axis and
act respectively on the housings to which they are connected to give them
longitudinal motion along the bracket support 23.
The upper portion of the housings 26 are formed as bearings 30, and located
and supported in these bearings is the slotted shaft 31. Located upon this
shaft are the bevel gears 32. These gears are loose on the shaft and therefore
capable of longitudinal motion on the shaft and receive motion from the shaft
through the instrumentality of the keys 33. The gears 32 mesh with the
gears 34, which are carried in the bearings 35.
Connected to the gears 34 are the short horizontal shafts 36. Mounted on
the shafts 37, which have their bearings in the dove-tail portion 27 of the
housings 26 and which are hexagonal on their upper end, are the edging rolls 38.

page_text: These rolls may be given any surface contour desired. That shown in the
drawings has two diameters, the greater diameter being at the bottom.
Mounted on the shaft 36 are the slotted clutches 39, having hexagonal open-
ings which correspond to the shape of the shafts 36 and 37. Vertical move-
ment is imparted to this clutch by means of the lever 40, which is pivoted
at 41 to the uprights 7. The inner end of this lever is forked as at 42 and
partially surrounds the clutch, to which it is loosely connected through pins 43,
which take in the slot 44 of the clutch 39. By means of the levers 40 the
edging rolls 38 can be thrown into and out of operation as desired.
45, 46, 47 and 48 represent gears intermediate of one of the main driving
shafts 21 and the shaft 31. The arrangement of these gears is such that the
speed of the facing rolls and edging rolls will be the same.
Mounted between the facing rolls and the edging rolls is the front guide 50,
and located behind the facing rolls is the back guide, 51. These guides con-
sist of pairs of opposing guide-boxes 52. The shape given to these boxes is
best shown in Fig. 5. That is, the boxes project at top and bottom toward
each other and have a cavity at or about their centres. The object of giving
them this shape is to cause them to direct the material passing through. the
machine in a straight line. I do not limit myself to the particular shape given
to the faces of these guide-boxes as it may be varied without departing from
the intent of my invention.
The guide-boxes 52 are mounted upon the horizontal plate 58, which is sup-
ported by the vertical side frames 54, secured to the uprights 7 of the machine.
The guide-boxes 52 are longitudinally adjustable upon the supporting plate 53,
and to or from the facing rolls 18, by means of the screws 55, and they are
also adjustable relatively to each other, i.e., transversely of the plate 53 by
means of the screws 56, so that the distance between them may be altered.
The side boxes 52 of the guide 50 project between the rolls 18" but are not
carried past the vertical axis of the rolls; whereas the side boxes of the guide 51
project past the vertical axis. This is the only difference of construction
between the guides 50 and 51, and this difference in construction is for the
purpose of preventing a strip when passing the rolls from following the curva-
ture of the rolls and turning upward. The shape of the side boxes projecting
through the rolls prevent this.
Located in front of the guide rolls 38, and supported upon the bracket 23,
are the vertically directing rolls 57 and horizontally adjustable directing rolls 58,
shown in Fig. 2.
The operation of my device is as follows:-The strip to be rolled and shaped
is introduced through the directing rolls 57 and 58 until it is caught by the
edging rolls 38, the edging rolls direct it into the guide 50, thence it passes
through the facing rolls 18 and finally out through the rear guide 51.
It will be observed that the path of movement of the strip through the
machine from the time it enters the directing rolls 38 is along a single hori-
zontal plane.
The result of the rolling is a copper body of definite and predetermined.
shape, straight and with finished edges.
As has been explained the contour of the body may be changed by altering
the relation of the axes of the facing rolls and contour of the edging rolls;
and bodies of different width may also be obtained by changing the distance
between the pairs of facing rolls and the pairs of edging rolls, or one rela-
tively to the other.
I do not wish to limit myself to the precise details of construction set forth
in this specification, as many changes may be made without departing from
the intent of my invention.
I wish to have it understood that I consider myself to be the first to employ
an organized machine for rolling copper forms wherein two sets of rolls acting
conjointly give shape to the body passing through them.
