SAMUEL GALLIE, of Birkenhead, in the County of Chester, Engineer. "IMPROVE-
MENTS IN BOLT MAKING MACHINES."
The said Invention relates to bolt making machinery or apparatus in which an
upsetting hammer or die is used in combination with side hammers or dies for
forming the head of the bolt. The object is to so construct, arrange, and operate
such machinery or apparatus that bolts shall be formed with a strong solid head,
free from arris or burrs and soundly and firmly joined to the shank, so that such
bolts shall be as strong and durable as the best hand forged bolts.
Under the first part of my Invention I construct bolt forging machines in
which an upsetting hammer or die and side hammers or dies act conjointly in
combination with apparatus or appliances for raising the bolt from its holder
whilst being acted on by the side hammers or dies.
Second. Apparatus for raising the said bolt mentioned under the above first
head consists of levers, cams, excentrics, or like appliances receiving motion at the
required times and to the requisite extent from any suitable moving part of the
apparatus, such as the mechanism for giving motion to the side hammers or dies.
Third. I combine together in machinery or apparatus for forging bolts an
upsetting hammer or die, side hammers or dies, and a rotating table provided with
a series of bolt holders, preferably six. The upsetting hammer or die and the side
hammers or dies are constructed, arranged, and operated in any ordinary or desired
manner. The table carrying the bolts is cansed to have an intermittent motion
at the desired times by means of ratchet or like gear.
Fourth. In bolt forging machinery or apparatus constructed under the above
third part the bolt holders are made free to swivel, and are provided with taper
grooves or slots through which the side hammers or dies pass to act on the bolt

page_text: head; the said hammers or dies also serve to adjust the position of the bolt holder
by means of the said taper grooves or slots.
Fifth. Machinery or apparatus constructed under the above third part of my
Invention is provided with any suitable or convenient apparatus for adjusting the
position of the table or bolt holders, or both, before being acted upon by the
hammers or dies.
Sixth. I combine together machinery or apparatus having a continuously
moving hammer or die, substantially as set forth in British Letters Patent,
No. 32597, or any apparatus similarly operating with side hammers and a rotating
table, arranged and operating substantially as above set forth. The side hammers
are operated by wedges, toggle joint, or any well known gear, and are by preference
two in number, shaped to fit the head of the bolt. Apparatus of any desired or
well known kind is used to eject the finished bolts from the holders. The
machinery or apparatus is driven by belting, toothed gear, steam, or bydraulic
power, as found most convenient.

SAMUEL GALLIE, of Birkenhead, in the County of Chester, Engineer. "IMPROVE-
MENTS IN BOLT MAKING MACHINES."
The said Invention relates to bolt making machinery or apparatus in which an
upsetting hammer or die is used in combination with side hammers or dies for
forming the head of the bolt. The object is to so construct, arrange, and operate
such machinery or apparatus that bolts shall be formed with a strong solid head
free from arris or burrs and soundly and firmly joined to the shank, so that such
bolts shall be as strong and durable as the best hand forged bolts.
Under the first part of my Invention I construct bolt forging machines in which
an upsetting hanımer or die and side hammers or dies act conjointly, in combi-
nation with apparatus or appliances for raising the bolt from its holder whilst
being acted on by the side hammers or dies.
Second. Apparatus for raising the said bolt mentioned under the above first head
consists of levers, cams, excentrics, or like appliances, receiving motion at the
required times and to the requisite extent from any suitable moving part of the
apparatus, such as the mechanism for giving motion to the said hammers or dies.
Third. I combine together in machinery or apparatus for forging bolts an
upsetting hammer or die, side hammers or dies, and a rotating table provided with
a series of bolt holders, preferably six. The upsetting hammer or die and the side
hammers or dies are constructed, arranged, and operated in any ordinary or desired
manner. The table carrying the bolts is caused to have an intermittent motion at
the desired times by means of ratchet or like gear.
Fourth. In bolt forging machinery or apparatus constructed under the above
third part the bolt holders are made free to swivel, and are provided with taper
grooves or slots through which the side hammers or dies pass to act on the bolt
head; the said hammers or dies also serve to adjust the position of the bolt holder
by means of the said taper grooves or slots.
Fifth. Machinery or apparatus constructed under the above third part of my
Invention is provided with any suitable or convenient apparatus for adjusting
the position of the table or bolt holders, or both, before being acted upon by the
hammers or dies.
Sixth. I combine together machinery or apparatus having a continuously
moving hammer or die, substantially as set forth in British Letters Patent,
No. 325978, or any apparatus similarly operating with side hammers and a rotating
table, arranged and operating substantially as above set forth. The side hammers
are opérated by wedges, toggle joint, or any well known gear, and are by preference
two in number, shaped to fit the head of the bolt. Apparatus of any desired or
well known kind is used to eject the finished bolts from the holders. The
machinery or apparatus is driven by belting, toothed gear, steam, or hydraulic
power, as found most convenient.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan view, Fig. 2 a side elevation, and Fig. 3 a sectional elevation of a
bolt making machine constructed with the improvements hereinbefore set forth;
Fig. 4 is a view of the rotating table and bolt holders.
Under the first and second parts of my Invention 1 is the upsetting hammer or
die, and 2 the side hammers or dies; 3 is the metal to be made into a bolt by
baving a head forged thereon. The said metal rests on the bearing piece 4 in the
table 5; 6, lever acted on at the required time by the bottom of the wedge piece 7
to raise the head of the bolt into position to be acted on by the side hammers
or dies.

page_text: Under the third head, 1, upsetting hammer; 2, side hammers; 5, table provided
with six bolt holders 8, and free to rotate on the central carrying pin or stem 9;
11, ratchet gear for giving intermittent rotary motion to the table 5.
Under the fourth part the bolt holders 8 are free to swivel on the table 5, and
are provided with taper grooves or slots 10, through which the side hammers 2, also
of taper form, pass to act on the head 12 of the bolt being forged. The taper form
of the slots and hammers ensures accurate adjustment of the parts before the said
hammers act on the head of the bolt.
Under the fifth part, 13 is a strap surrounding and bearing against the table 5,
and tightened by screws and nuts 14 for the purpose of keeping the table steady
and preventing it from being turned too far by the ratchet gear 11.
Under the sixth part, 15, driving pulley, and 16 shaft by which continuous up
and down motion is communicated to the upsetting hammer through the crank and
slide 17 and to the wedge pieces 18 through excentrics 19; 20, driving gear working
continuously, and giving a rising and falling motion to the whole of the frame 21,
carrying the upsetting hammer 1, wedge pieces 18, and driving gear 15, 16, by
means of the connecting rods 22, substantially as set forth in the Specification to
British Letters Patent, No. 325973, granted to me, so as to bring the said hammer
and wedge pieces into position to act on the bolt. The said driving gear 20 also
gives motion to the ratchet 11 which actuates the table 5.
The action of the apparatus is as follows:-The driving gears 15 and 20 are set
in motion. The driving gear 15 gives the upsetting hammer 1 and wedge pieces 18
a rapid up and down motion, at the same time the gear 20 causes the table to
rotate intermittently one sixth of a revolution so as to bring each of the bolt
holders 8 alternately beneath the hammer 1. As each bolt holder arrives beneath
the hammer 1 the table has a period of rest, during which the whole of the frame 21,
hammer 1, and wedge pieces 18 are caused to descend by the said gearing 20. The
upsetting hammer 1 and side wedges act alternately, so that when the said
hammer 1 is raised the wedge pieces 18 cause the side hammers 2 to give a blow
to the sides of the head of the bolt, and at the same time one of the said wedge
pieces strikes against the lever 6, so as to raise the upset portion of the metal 3
above the table 5 and allow it to be more advantageously acted on by the side
hammers 2. The hammer 1 then gives another blow on the head of the bolt and
the side hammers are withdrawn by the springs 23; 24, lever and trip piece for
ensuring the withdrawal of the side hammers if the springs fail to act; 25, cam
acting on the lever 26 to eject the finished bolt from the holder after it passes from
beneath the upsetting hammer. The metal from which the bolts are formed is cut
into the required lengths and placed in the holders by hand.
Having now described and illustrated the nature of the said Invention in such
manner that others will be enabled to carry the said Invention into practice, I
claim,―
The improvements in bolt making machines, substantially as herein set forth.
In witness whereof, I, the said Samuel Gallie, have hereunto set my hand
and seal, this Twelfth day of April, in the year of our Lord One thousand
eight hundred and eighty one.
