I, BENJAMIN BAUGH, Manager of Thomas Clutton Salt's Enamel Works,
Bradford Street, Birmingham, in the County of Warwick, do hereby declare
the nature of my said Invention for "CERTAIN IMPROVED ARRANGEMENTS FOR
WORKING FLY PRESSES BY STEAM, WATER, OR OTHER POWER," to be as follows
(that is to say):
My Invention consists in arranging two fixed stays or guide rods in any
convenient way above the press, which may be of the ordinary construction,
with the exception that the barrel of the screw is made to extend, forming as
it were a vertical shaft, working vertically and centrally between the guido
rods before named. On this vertical shaft two reversed conical bosses are
formed. The guide rods are constructed with vertical slots or grooves in which
a top and bottom bar is made to traverse in the following way:-The top
pulley is bored to fit freely on the vertical shaft, but on the under side a socket
is formed to correspond with the top conical boss before described, so that
when the screw of the press rises, until the top boss is brought in contact with
its corresponding socket in the top pulley, which rests on the top traversing
bar, and motion being given to the pulley (by a band working around a
suitable drum), the contact of the conical boss of the shaft with the socket of
the pulley will be sufficient to impart a motion to the screw of the press,
which as it revolves, descends, and a heavy fly wheel being fixed on the

page_text: vertical shaft near that part where the screw terminates, a blow will be given
by the descending screw and momentum of the fly. The transverse bars being
regulated according to the distance the screw ascends and descends, or depth
of the work, and simultaneously with the striking of the blow a spring clutch
connected with the top bar passing over inclined planes, frees tho top pulley
from its corresponding conical friction clutch, and at that moment the lower
boss is by identically the same arrangement of spring clutch, inclines, and
other parts, brought in contact with the lower pulley, which working in a
contrary direction reverses the action of the screw and fly, causing it to rise
up for the next blow, when it will free itself from the shaft, which will continue
to rise by the momentum of the fly until the top boss is again brought in
working contact with the socket of the top pulley; thus we get a continuous
elevating and descending action of the press, screw, and tool, giving form to
metal or other material that may bo desired to be formed or finished in dies or
moulds by such means. In some instances where for want of room or other
convenience, I so arrange my pulleys that they shall always maintain the same
position, and in that case I prefer that my conical bosses shall be made to slide
on the shaft by having a projection on the clutches or bosses to work in a
parallel groove made in it for that purpose, so that instead of bringing the
pulley to the boss or friction clutch, I bring the reverse bosses to their respective
pulleys above and below, by which I obtain identically the same result.
Although I have described this arrangement as working vertically, nevertheless
it is capable of being worked in a slanting or horizontal direction, or the
whole arrangement may bo reversed, that is, the tool in connection with
the screw may be elevated to its die or work instead of working in the
reverse direction before described.
