Year: 1875

page_text: LETTERS PATENT to Benjamin William Rogers, of Stourport, in the
County of Worcester, Machinist, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR THE MANUFACTURE OF SCREWS AND BOLTS AND
OTHER LIKE ARTICLES."
Scaled the 4th June 1875, and dated the 26th January 1875.
PROVISIONAL SPECIFICATION left by the said Benjamin William
Rogers at the Office of the Commissioners of Patents, with his
Petition, on the 26th January 1875.
I, BENJAMIN WILLIAM ROGERS, of Stourport, in the County of
Worcester, Machinist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF SCREWS AND BOLTS
AND OTHER LIKE ARTICLES," to be as follows:-
:-
My Invention has reference to those portions of machinery used in
the manufacture of screws, bolts, pins, and other like articles, which
have for their function the feeding of the blanks or partially made
articles into those portions of the machinery in which the blanks or

page_text: partiany made articles are worme, I us
upon.
For convenience of description I will describe my Invention in con-
nection with screw-making machinery:-A feeding rail of the ordinary
kind is employed down which the blanks pass. The said rail is situated
vertically but is bent at its bottom at an angle of about forty-five
degrees. The blanks are removed one at a time and transferred to the
clams by which they are seized and held while being operated upon by
mechanism constructed as follows:--An arm or lever working in a
vertical plane and operated as herein-after explained carries at its end a
finger so inclined and having such a curvature on its outer side that
when the lever turns upon its centre the curved outside of the said
finger during its motion bears against and closes the opening at the
bottom of the rail and prevents the descent of the column of blanks.
This finger being fixed to the said lever and having no independent
motion I will call the fixed finger. To the said fixed finger a second or
sliding finger is connected by a pin in the former taking into an oblong
hole in the latter. The bottom end of the fixed finger is cut away at its
middle so as to give it a fork shape, and the lower end of the sliding
finger is turned nearly at right angles under the end of the fixed finger
so that a blank introduced between them is on the raising of the sliding
finger held by the end of the sliding finger in the fork of the fixed
finger. A spring acting on the sliding finger tends to keep it in its.
raised position.
When the lever carrying the fingers is in its raised position the forked
end of the fixed finger is just above the opening in the feeding rail,
while the sliding finger having been just before brought into contact
with a fixed stop was arrested in its motion before the fixed finger had
risen to the position last described. The result of the action described
is that the ends of the fingers are sufficiently separated to permit a
blank to pass from the feeding rail between the ends of the said fingers.
On the descent of the lever the fixed finger first advances, seizing the
blank between it and the end of the sliding finger, the two fingers now
descend together holding the blank between them. The clams close
upon and retain the blank. The lever now ascends and the sliding
finger yielding permits the escape of the blank from the fingers. When
the lever arrives at the top of its stroke the opening of the fingers and
the reception of another blank takes place.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Benjamin William Rogers in the Great Seal Patent
Office on the 30th June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
WILLIAM ROGERS, of Stourport, in the County of Worcester, Machinist,

Britain and Ireland, the. Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF SCREWS AND
Bolts and cther LIKE_ARTICLES," upon the condition (amongst others) that
I, the said Benjamin William Rogcis, my exccutors or administrators,
by an instrument in writing under my, or their, or one of their hands
and scals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Datont

page_text: NOW KNOW YE, that I, the said Benjamin William Rogers, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :—
My Invention has reference to those portions of machinery used in
the manufacture of screws and bolts and other like articles, which have
for their function the feeding of the blanks or partially made articles
into those portions of the machinery in which the blanks or partially
made articles are wormed, nicked, turned, or otherwise operated upon.
For convenience of description I will describe my Invention in con-
nection with screw-making machinery. A feeding rail of the ordinary
kind is employed down which the blanks pass, the said rail is situated
vertically but is bent at its bottom at an angle of about forty-five
degrees. The blanks are removed one at a time and transferred to the
clams, by which they are seized and held while being operated upon by
mechanism constructed as follows:-An arm or lever working in a
vertical plane and operated as herein-after explained carries at its end a
finger so inclined and having such a curvature on its outer side that
when the lever turns upon its centre the curved outer side of the said
finger during its motion bears against and closes the opening at the
bottom of the rail and prevents the descent of the column of blanks.
This finger being fixed to the said lever and having no independent
motion I will call the fixed finger. To the said fixed finger a second or
sliding finger is connected by a pin in the former taking into an oblong
hole in the latter. The bottom end of the fixed finger is cut away so as
to give it a fork shape, and the lower end of the sliding finger is turned
nearly at right angles under the end of the fixed finger, so that a blank
introduced between them is on the raising of the sliding finger held by
the end of the sliding finger in the fork of the fixed finger. A spring
acting on the sliding finger tends to keep it in its raised position.
When the lever carrying the fingers is in its raised position the forked
end of the fixed finger is just above the opening in the feeding rail,
while the sliding finger having been just before brought into contact
with a fixed stop was arrested in its motion before the fixed finger had
risen to the position last described. . The result of the action described is
that the ends of the fingers are sufficiently separated to permit a blank
to pass from the feeding rail between the ends of the said fingers. On

page_text: the descent of the lever the fixed finger first advances, seizing the blank
between it and the end of the sliding finger; the two fingers now
descend together holding the blank between them. A horizontal motion
is then imparted to the lever carrying the fingers by a spring acting
upon the axis of the lever, thereby carrying the blank between the clams
which close upon and retain it. The lever now ascends, and the sliding
finger yielding permits the escape of the blank from the fingers. When
the lever arrives at the top of its stroke the opening of the fingers and
the reception of another blank takes place.
During the descending and ascending motions of the fingers, the
curved side of the fixed finger closes the bottom of the feeding rail and
prevents the descent of the blanks.
The ascending motion of the lever is effected by a cam on the cam
shaft of the machine, and its descending motion by a coiled or other
spring, or by its own weight.
Having explained the nature of my Invention, I will proceed to
describe with reference to the accompanying Drawing, the manner in
which the same is to be performed.
Figure 1 represents in side elevation, and Figure 2 in plan, a machine
for turning the heads of screw blanks provided with feeding mechanism
constructed according to my Invention.
Figures 3 and 4 represent cross sections of the machine taken on
the line A, A, of Figure 2, Figure 3 representing the feeding mechanism
in its lowest position in the act of feeding a screw blank to the clams,
5 and Figure 4 representing the feeding mechanism in its highest position
in the act of receiving a screw blank from the feeding rail.
Figure 5 represents in front and side elevation the fixed and moveable
fingers of the feeding mechanism detached.
The same letters of reference indicate the same parts in the several
Figures of the Drawing.
a is the feeding rail down which the column of blanks or partially
made articles pass to the feeding mechanism. The bent lower end of
the feeding rail is open, and from the said open end the blanks are
removed one at a time, and transferred to the clams p by the action of
5 the fingers c and d, carried by the arm or lever b. The said arm or.

page_text: lever has a rocking motion as well as a horizontal sliding motion given
to it in the manner herein-after described. The shaft or spindle i of the
arm or lever oscillates and slides in the fixed bearings k, k, (see Figure 2).
The finger c of the feeder is fixed to the lever b, but the finger d has a
limited sliding motion upon the said fixed finger c. The said sliding
finger d is connected to the fixed finger c, by a pin c³, in the said fixed
finger c working in an oblong slot d³, in the said moveable finger the extent
to which the said sliding finger can have motion upon the fixed finger
being limited by the said slot d³. A coiled spring e connected to the
head of the sliding finger d tends to raise it to its highest position, or
the position represented in Figures 3 and 5. The outer side of the fixed
finger c is curved as represented, the curve of the said outer side being
struck from the centre i, on which the arm or lever & turns.
By means of the said curvature of the outer side of the fixed finger c
it closes the opening in the bottom of the feeding rail a during the
ascending and descending motions of the lever b, as seen in Figure 3, so
as to prevent the descent of the column of blanks in the said feeding
rail. The bottom end of the fixed finger c is forked at c and the lower
end of the sliding finger d is hooked at d', or is turned nearly at right
angles under the end of the fixed finger c, as best seen in Figure 5. It
is between the hooked end d of the sliding finger d and the fork c² of
the fixed finger c that the blank q is held for feeding it to the clams p;
f is a fixed stop for arresting the rising motion of the sliding finger d
preparatory to the feeding of a blank between the fixed and sliding
fingers c, d.
By an examination of Figures 4 and 3 the respective positions of the
several parts of the feeder when a blank is being fed to the fingers c, d,
and the blank held between the said fingers and carried down and trans-
ferred to the clams will be readily understood. In Figure 4 the lever b
carrying the fingers c, d, is represented in its highest position, the fixed
finger e being raised just above the opening in the bottom of the feeding
rail a, the sliding finger d having been arrested in the position represented
in the said Figure 4 by coming against the stop f. The ends of the
fingers c, d, are thus sufficiently separated to permit the blank q to pass
from the feeding rail a between the ends of the said fingers. This
having taken place the lever descends, carrying the feeder to the
position represented in Figure 3, the curved outer side of the finger c
closing the opening in the bottom of the feeding rail a. On the descent

page_text: the opposite end of the lever 12 bearing against a collar on the spindle i
to which the lever 6 is fixed.
As the other parts of the head turning machine which I have not
described are not of my Invention I do not think it necessary to describe
the same.
Although I have only described my improved feeder in combination
with a head turning machine, yet the said feeder is equally applicable
to the feeding of blanks or partially made articles into other machines,
such as worming and nicking machines.
Having now described the nature of my Invention, and the manner
in which the same is to be performed, I wish it to be understood that
I do not limit myself to the precise details herein described and illus-
trated, as the same may be varied without departing from the nature of
my Invention; but I claim as my Invention, the improvements in
machinery for the manufacture of screws and bolts and other like
articles herein-before described and illustrated in the accompanying
Drawing, that is to say, constructing the feeding mechanism of the
said machinery of two fingers carried by an oscillating and sliding
lever, one of the said fingers being fixed to the said lever, and the
other finger having a limited sliding motion upon the said fixed finger,
the several parts of the said feeding mechanism being constructed,
combined, and worked substantially as and for the purposes described
and illustrated.
In witness whereof, I, the said Benjamin William Rogers, have
hereunto set my hand and seal, this Twenty-eighth day of June,
in the year of our Lord One thousand eight hundred and soventy
