Improvements in Apparatus for Use in the Manufacture of
Metal Plates.
1, GEORGE ALBERT DEAN, of Mingo Junction, in the County of Jefferson,
State of Ohio, United States of America, Manufacturer, 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:-
Figure 1 indicates a plan view of my improved apparatus for conveying to and
maintaining plate in a bosh.
Figure 2 is a side elevation of the same.
Figure 3 is an enlarged view of the clutch mechanism, rack-bar, carriages
connected thereto, and means of operating the same.
Figure 4 is a side elevation of cogs 'meshing with rack-bars; also sectional end
view showing manner of connecting carriages.
Figure 5 is a plan view of shaft 31 and pulleys thereon.
Heretofore, so far as I am aware, it has been impossible to handle or convey
large tonnage of bars intended for the manufacture of tin and terne to the bosh,
and to mauipulate the same therein without causing buckling or bending up.
The object of my invention, is, first, to produce an apparatus for conveying
large tonnage of plate or sheet, especially intended for the manufacture of tin
and terne plate, to the bosh, and maintaining the same therein in such manner as
to prevent the before mentioned buckling or bending; secondly, the production of
an apparatus by the use of which the operation of rolling the plates or sheets,
boshing, and shearing the same, is performed substantially without interruption,
heretofore unavoidable-that is to say, the rolls, bosh-tank, and shears are arranged
in such manner with relation to the carriages which convey the plates or sheets
from the rolls to the shears and support the plates or sheets while being boshed,
that during the time either of said carriages is opposite the rolls receiving plates
or sheets, and with its contents in the bosh-tank, the other carriage is opposite one
of the shears and the plates or sheets thereon being reduced to suitable lengths,
whereby, as before stated, the threefold operation of rolling, boshing, and shearing
is practically continuous, thus economizing time and labor and greatly increasing
the product of the mill.
I will now describe my invention, reference being had to the accompanying
drawings, forming part hereof, in which like letters and figures indicate like parts
wherever they occur.
Referring to said drawings, 1 and 1' indicate, respectively, shears located at one
end and on each side of a bosh-tank 2, and adapted to be operated in any usual
At the opposite end of said bosh-tank and immediately opposite the end
thereof, are located finishing-rolls 3, which likewise may be driven in any usual
manner.
manner.
4 and 4' are carriages mounted on wheels and adapted to be moved on ways or
tracks 5-5, as hereinafter specified, whereby long bars A of tin and terne plate,
when passed through and finished on said rolls 3, are received and supported upon
a series of rollers 6 and 6', respectively, journaled in the sides of said carriages 4
and 4', respectively, and after being boshed, as hereinafter specified, conveyed to
the shears 1 and 1', respectively, for the purpose of being cut into suitable lengths.
Said carriages are, as heretofore stated, mounted on ways or tracks and are capable

page_text: of being moved laterally thereon simultaneously by bars 7-7, to the inner ends,
respectively, of which are bolted or otherwise suitably secured the rods 8-8, which
project downwardly therefrom on each side of the carriages parallel with the sides
thereof through orifices formed in lugs 9-9, which are bolted upon the top of the
sides of said carriages and project at right angles therefrom, as shown in Figure 4.
The lower ends of the rods 8-8, which project downwardly between the carriages,
are connected by bars 91, the rods 8 on the opposite side, respectively, of said
carriages being made rigid and firm by the brace-bars 10-10, the ends of which,
respectively, are secured to the lower ends of said rods 8 and to bars 7-7, as shown
in Figure 4. The rods 8-8 fit loosely in holes formed in the lugs 9-9 to permit
either of said carriages when being lowered into the bosh-tank and elevated there-
from to slide freely on said rods, whereby either of said carriages with the plate
thereon can be lowered into the bosh-tank (when immediately over the same) by
the hydraulic lifts, as hereinafter specified, without being disconnected or uncoupled
from the other, as shown in Figure 4, and also to admit of said carriages being,
when out of the bosh-tank and on the same horizontal plane, moved laterally
simultaneously, as hereinafter specified. The outer lower ends of said bars 7-7,
are respectively provided with racks 11-11, which engage cogs 12-12, mounted
on the shaft 13, between the standards 14 and 14', which carry bearings for said
shaft. Said shaft is provided with a cog 15, which meshes with and receives power
from a similar cog. 16, mounted on the end of the horizontal shaft 17, which is
journaled in bearings 18, formed in the standards 14, 14¹. The end of said shaft
opposite that on which the cog 16 is mounted, is provided with a bevel or miter
wheel 19, adapted to mesh with and receive power alternately from the miter-
wheels 20 and 21, which are loosely mounted on the shaft 22, which is journaled in
bearings formed in the standards 23, accordingly as either of said wheels 20 and 21
are rigidly secured on said shaft 22, by the clutch 24, located on said shaft 22,
between said bevel-wheels 20 and 21, loosely secured thereon, whereby power
transmitted through the belt-pulley 25, mounted on said shaft 22, transmits power
thereto, and to whichever of the said miter-wheels 20 and 21 that is made rigid on
said shaft by said clutch, thence to the beveled wheel 19 and the cog 16, thence to
the large cog 15, mounted on shaft 13, and to the cogs 12-12, mounted on said
shaft, which mesh with the racks 11-11 on the ends of said bars 7-7, respectively,
whereby said carriages are moved from and towards the bosh alternately,
accordingly as either of said beveled wheels 20 and 21 are fixed rigid upon said
shaft 22, whereby the carriages are moved alternately into a position opposite the
rolls and over the bosh-tank, and are adapted to be lowered when in such position
into said tank by the hydraulic lifts 26-26, located in the bottom of the same
.without being disconnected from the other carriage, then opposite one of the pairs
of shears, being coupled, as heretofore stated, in the manner shown in Figure 4, to
admit of this.
27 is a pair of tongs connected to the chain 28, adapted to be coiled around a
drum or spool 29, which projects from the side and is integral with the loose
pulley 30 on shaft 31, whereby when power is applied to the belt 32, the bar or
sheet seized by said tongs is caused to move towards and into the jaws of the
shears and cut into suitable lengths.
33-33 are small rolls mounted on the short shafts 34, journaled in the top of
the standards 14 and 14', and impinges upon the top of the rack-bars immediately
above the cog-wheel which engages the rack on the under side of the same, for
the purpose of guiding said rack-bars and maintaining the same in mesh with
the cogs.
The shaft 31, on which is mounted the loose pulley 30, is provided with a
pulley 35, rigidly secured upon the same, for the purpose of enabling the belt 32 to
be shifted from said pulley 30 to the pulley 35, when it is necessary to uncoil the
chain after each successive sheet has been sheared, and to enable another sheet
resting on either of the carriages, to be seized by the tongs, as shown in
Figure 2.

page_text: The operation of my device is as follows, viz. :
The carriages standing in the position shown in Figure 1, carriage 4 being
opposite the rolls and over the bosh-tank, is loaded with plates or sheets from said
rolls, lowered into the bosh, as before described, elevated therefrom, and, the
bevel-wheel 20 being thrown in clutch with the miter or bevel-wheel 19, power
applied to the belt-pulley in any usual manner, moves the rack-bars and the
carriages connected therewith aud coupled together by the rods which project
downwardly therefrom through openings in lugs secured to the top of the sides of
said carriages in the direction of shears 1, thus bringing the carriage 4 opposite
shears 1, as indicated by dotted lines, Figure 1, and carriage 4' into the position
just vacated by carriage 4. Carriage 41 is loaded with plates or sheets, as hereto-
fore specified, and lowered into the bosh-tank. The contents of carriage 4 mean-
while being sheared, carriage 4' is raised out of the tank and the mechanism which
operates the rack-bars reversed, causing the carriages to be moved into their
original position, carriage 41, however, being loaded with sheets or plates to be cut.
into suitable lengths by shears 1', and this operation is continued successively
without interruption.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim, is-
