This invention relates to improvements in wire-drawing apparatus, and refers
more particularly to what is known as continuous drawing, that is, where two
or more (usually about four) operations are continuously performed from one block
to another.

Its objects are primarily to provide means whereby the wire, the blocks,, and
the plates are submerged in a lubricating solution; also that the transverse
strain upon the block vertical spindles is relieved; and also that in some cases
where the blocks and plates are dry, that is, the course of the wire is straight
and above the solution, the said wire is lubricated by means of lubricating rollers
whose lower parts pass through the solution and thus convey it to and distribute
it upon the wire in its travel.

According to this invention the vertical spindles. for driving, the blocks, and
the bolsters for supporting the draught plates, and other necessary brackets or
the like, together with the final drum (block) are all formed and carried upon
a suitable frame, or table, to which is attached in a suitable, manner the necessary
driving mechanism. The upper part of the frame is formed into one large trough
of a depth so that when charged with the, necessary, solution, the blocks, and
plates and the wire shall be submerged, the final block usually being preferred
to be elevated above it. Preferably also I provide what is practically a separated
part in such trough through which the wire in its first operation passes, so that
the dirt &c. from the wire at such stage is arrested and held in such compartment.
A small opening or communication is however made between such compartment
and the general trough, through which the wire may pass and through which
the common level may be maintained. By these means; a more perfect.lubrication
of the wire is effected, while, the wire, the. blocks, and the plates are kept icom-
paratively, cool.
In some cases I may effect the lubrication of the wire by making the trough
more shallow so as not to reach the line of wire, but which latter shall neverthe-
less travel in a straight line from block to plate &c., and further provide lubri-
cating rollers upon which the wire shall travel and by which they shall be revolved.
The lower part of such rollers however shall reach and pass through the solution,
and thus as they revolve shall carry the solution to their upper-sides. and thus
come in contact with the wire. These rollers may be of any suitable shape or
material which shall best effect their purpose.

Again: Upon the upper side of the frame or table and where the vertical
spindles are located I provide upstanding bosses through which are formed the
halda h

page_text: bearing holes for the said spindles. The exterior of these bosses are turned
and the blocks bored to fit them, so that the blocks may revolve thereon, thus
transferring the horizontal pulling strain from the spindle to the boss upon the
table. The said blocks are driven by means of a. dog, movably carried upon a
square formed upon the upper end of the spindle, which extends upwards above
the block.

Improvements in Wire Drawing Apparatus.
I, EDWARD SAMUEL BOND, of Crown Works, Booth Street, Handsworth, in
the County of Stafford, Mechanical 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:-
This invention relates to improvements in wire drawing apparatus, and refers
more particularly to what is known as continuous drawing, that is, where two
or more (usually about four) operations are continuously performed from one block
to another.
Its objects are primarily to provide means whereby the wire, the blocks, and
the plates are submerged in a lubricating solution; also that the transverse
strain upon the block vertical spindles is relieved, and also that in some cases
where the blocks and plates are dry, that is, the course of the wire is straight
and above the solution the said wire is lubricated by means of lubricating rollers
whose lower parts pass through the solution and thus convey it to and distribute
it upon the wire in its travel.
In order to more clearly explain this my invention, I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part, and
in which:-
Fig. 1, is a plan view of the apparatus.
Fig. 2, is a sectional side view of the apparatus on line A-B.
Fig. 3, is a sectional view on line C-D.
Fig. 4, comprises a side view and an inverted view of the driving (or dog)
plate.
Fig. 5, is a plan view in detail of a block.
Fig. 6, is a view. in sectional elevation showing the driving plate and spindle
device applied to a double block.

According to this invention the vertical spindles for driving the blocks, and
the bolsters for supporting the draught plates, and other necessary bracketsɗ
the like, together with the final drum (block) are all formed and carried un
a suitable frame, or table, to which is attached in a suitable manner the necessary
driving mechanism.
The class of machine to which these my improvements more particularly apply
may be readily understood by reference to Specification for Letters Patent No. 5221
of 1895, but it will also be understood that the spindles for the blocks may be driven
by any suitable means other than that shown, also that the disposition and number
of blocks may be varied if desired.

page_text: In this my invention, the upper part of the frame 10, is formed into one large
trough 11, of a depth so that when charged with the necessary solution, the
blocks 12, and plates 13, and the wire 14, shall be submerged, the final plate 15,
usually being preferred to be elevated above it. Preferably also I provide what
is practically a separated compartment 16, in the trough through which the wire
in its first operation passes, so that the dirt &c. from the wire at such stage is
arrested and held in such compartment, and thereby keeping the solution in the
general trough much cleaner than it otherwise would be. A small opening or
communication 17, is however made between such compartment and the general
trough, through which the wire may pass and through which the common level
of the solution may be maintained. By these means a more perfect lubrication
of the wire is effected, while the wire, the blocks, and the plates are kept com-
paratively cool, by reason of the large body of solution presenting a large exposed
cooling surface and the entire wire throughout the circuit being immersed.
In some cases as shown in Fig. 7, I may effect the lubrication of the wire by
making the trough shallow, so as not to reach the line of wire, but which latter
shall nevertheless travel in a straight line from block to plate &c. by providing
lubrication rollers 18, upon which the wire shall travel and by which they shall
be revolved. The lower part of such rollers however shall reach and pass through
the solution, and thus as they revolve shall carry the solution to their upper sides
and thus the solution is given on to the wire. These rollers may be of any suit-
able shape or material which shall best effect their purpose.
I will now describe the block 12, and the manner in which it is carried upon
the table. Upon the table is cast in one therewith the upstanding boss 19,
through which the driving spindles 20, pass, at the upper end of which latter is
formed the square portion 21. The block 12, is turned to revolvably fit the
boss 19. At the lower part of the block is the stationary collar 22, into which
the block 12, enters a short distance. This prevents the wire from getting
jammed into any joint which would take place if the bottom of the block were
not thus protected. At the upper part of the block is the depending flange 23,
which is secured thereto by screw pins 24. Through this flange and also pene-
trating the block, are driving holes 25. Upon the upper end of the spindle 20,
is now passed the dog (driving) plate 26, having the projecting studs 27, which
take into holes 25, so that thereby the particular block may be driven. It will
be seen that the said dog plate may be readily removed if desired.
In some cases a second tier or series of blocks may be arranged one above the
other as shown in Fig. 6, but I do not claim such except in so far as the insertion
collars 22, 23", studs 27 in combination therewith.
By these means the pulling strain of the wire is relieved from the spindle 20,
and transferred to the boss 19, which presents a larger surface for wear and is
also thereby less liable to create heat, besides forming a perfect wall to the
solution.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
ן!
1. A wire drawing machine having an entire trough in which the blocks, the
lates, and the whole circuit of wire are submerged in solution excepting the final
draw, substantially as set forth and shown.
2. In wire drawing machines, the employment of a preparatory or dirt solution
compartment 16, substantially as set forth and shown.
3. The method of carrying the revolving wire blocks 12, upon the fixed cast
Loss 19, through which centrally passes the driving spindle 20, as set forth
and .shown.
4. The combination with the blocks 12, of the collar 22, or 23, or both as
the case may be, into which the said block enters, as set forth and for the purposes
specified.
