page_text: LETTERS PATENT to Robert Simpkin Piercy of Blackburn in the County of,
Lancaster Mechanic for an Invention of AN IMPROVED FEED FOR ROLLERS,
AND PURIFIERS, ALSO
PURPOSES
APPLICABLE
AS A FEED FOR OTHER MILLING -
COMPLETE SPECIFICATION filed by the said Robert Simpkin Piercy at
the Office of the Commissioners of Patents on the 28th July 1883.
ROBERT SIMPKIN PIERCY of Blackburn in the county of Lancaster. Mechanic.
AN IMPROVED AUTOMATIC FEED FOR ROLLERS AND PURIFIERS, ALSO APPLICABLE
AS A FEED FOR OTHER MILLING PURPOSES.
The object of my invention is to automatically regulate the feed from the,
hoppers to the rollers, so that however unevenly the hoppers are fed, by my
arrangement the feed to the rollers, is regulated and self-adjusting, and so evenly
distributes the substance to the rollers, along the entire length.
Instead of the feed board or regulator board being attached in the form of a
slide and adjusted by a thumb screw, I pivot the feed or regulator board and
adjust it by a thumb screw, so as to limit the feed so that no flush can take place,
whatever quantity of substance there is in the hopper but I automatically regulate
it by a screwed stud or lever attached and standing out below its pivot, upon this
stud is a weight preferably tapped or screwed on to it, the weight I make circular
but tap it out of the centre, so that it is eccentric to the stud and so will not move
or alter its position with the jarring and sbake of the machine, the amount of
leverage can at the same time be regulated at will, the above arrangement is
applicable to purifiers, or other feeds used in milling purposes.
Such being the nature and object of this my said invention in in order that
the same may be fully understood, I have hereunto annexed one sheet of drawings
illustrative thereof and have marked the same with figures and letters of reference
similar letters referring to similar parts throughout the several views

page_text: DESCRIPTION OF DRAWINGS
Fig. 1 is an elevation in section of part of hopper and rollers with my
automatic regulating feed attached.
Fig. 2 is a front elevation of Fig 1
A is the hopper, G is the feed roller, B the feed or regulator board pivotted
at C, D is the thumb screw for regulating or limiting the feed so that no flush can
take place whatever quantity of substance there is in the hopper, the thumb screw D
is carried in a suitable bracket E, the quantity of substance passing from the
hopper is regulated by a lever or screwed stud F, attached and standing below the
pivot C, of the regulator board B; this stud carries a circular weight or weights H, H,
preferably screwed or tapped upon the stud or lever, eccentric to it, so that the
jarring or shake of the machinery does not move or displace the same, the amount
of leverage can be regulated at will either by the-weights. or. by altering the
position of the stud or lever, near to or further from the pivot of the regulator
board, or by altering the angle of the same (or a spring may be used) by the above
arrangement the feed is automatically regulated from the hopper to the rollers,
and however unevenly the hoppers are fed, the feed to the rollers is even and
steady, and distributed throughout their entire length, the above arrangement is
also applicable to purifiers or other feeds used in milling purposes; if required two
or more studs and regulating screws may be used.
Having thus fully described and particularly ascertain the nature and object
of this my said invention and the manner in which the same is to be performed
or carried in to practical effect, I would have it understood that what I claim
as the invention to be secured to me by the heroinbefore in part recited Letters
Patent is.
1. The combination of the pivotted regulater board B, and the adjustable
regulating weighted lever F constructed and operating-as-shewn and described -
2 The combination of the pivotted regulater board B, and the adjusting or
limiting screw D constructed and operating as shewn and described
In witness whereof I tho said Robert Simpkin Piercy have hereunto set my
hand and scal this twenty fifth day of July in the year of our Lord one thousand
eight hundred and eight [sic] three.
