Year: 1872

page_text: LETTERS PATENT to Henry Chancellor, of Birmingham, in the
County of Warwick, Machinist, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR THE MANUFACTURE OF HINGES AND OTHER JOINTED
METALLIC ARTICLES, AND FOR OTHER LIKE PURPOSES."
Sealed the 25th March 1873, and dated the 12th October 1872.
PROVISIONAL SPECIFICATION left by the said Henry Chancellor at the
Office of the Commissioners of Patents, with his Petition, on the
12th October 1872.
I, HENRY CHANCELLOR, of Birmingham, in the County of Warwick,
Machinest, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF HINGES AND OTHER
JOINTED METALLIC ARTICLES, AND FOR OTHER LIKE PURPOSES," to be as follows:-
My Invention consists of the construction and combinations of parts
herein-after described of machinery for slotting the flaps of hinges, that
is, forming or finishing the openings in the knuckles of the said flaps,

page_text: flaps for receiving the joint pin.
Although my Invention is especially useful for slotting and drilling
hinges, yet it may also be applied to the slotting and drilling of the
parts of other jointed articles, such, for example, as the joints of banner
screens and the horns of castors, and for other like purposes.
I will describe my Invention as applied to the manufacture of
hinges.
The machine for slotting the flaps of hinges, or for finishing or
dressing the openings in the said flaps, consists essentially of a pair of
rotating files or cutters, under which a travelling bed or table carrying
the hinge flaps to be operated upon slowly passes. The said files or
cutters are mounted upon a horizontal driving shaft, to which a rapid
rotatory motion is given. The distance between the files or cutters is
adjusted by filling up discs. The travelling bed or table works upon a
dovetail on an adjustable bed plate, and the upper side of the said bed
or table is of a box form. A series of hinge flaps placed face to face is
so arranged that the slots or openings in the knuckles of the several
flaps are opposite one another or in the same line. The flaps packed
together in this way are placed in the travelling bed or table, and
clamped therein by set screws, or otherwise secured, the slots or openings
in the several flaps being opposite the rotating files or cutters. By the
rotation of the files or cutters and the motion of the travelling bed or
table the hinge flaps are brought under the operation of the said files or
cutters, and the slots or openings in the flaps are dressed or finished.
Great uniformity in the size of the openings in the flaps is thus obtained,
and the flaps are ready without further preparation to be fitted together
for the drilling process herein-after described. Instead of dressing or
finishing the openings in the flaps the openings themselves may be made
by the operation of the rotating files or cutters.
By means of the adjustable bed plate carrying the travelling table and
by set screws the height of the said table may be adjusted to suit hinges.
of different sizes.
The slow motion of the travelling table is taken from the shaft of the
-On the said shaft are
rotating files or cutters in the following manner :—
two worms which gear with and communicate motion to two worm

page_text: wheels mounted on vertical shafts. The lower ends of these vertical
shafts carry toothed pinions which respectively gear with toothed racks
on the longitudinal edges of the travelling bed or table, and thereby give
to the said table the motion necessary to carry it slowly under the
rotating files or cutters.
The machine for drilling the holes in the knuckles of hinge flaps for
the joint pin of the hinge consists essentially of a vertical drill point
uppermost, having only a rotatory motion and a vertical slide supporting
the hinge flaps to be drilled, the said slide by a descending motion
carrying the knuckles of the flaps against the rotating drill. The slide
is furnished with a bed or holder having a depression in it of a shape
proper to receive a partly made hinge, the flaps of which have been
fitted together by the engaging of their solid knuckles with the openings
in their respective flaps. The knuckles of the combined flaps are so
situated that they are coincident with the axis of the drill. The com-
bined flaps are firmly secured in the bed or holder by a jointed cover or
lever, having on its inner side a V shaped projection which fits between
the two flaps laid in the bed or holder. Other means however may be
used for securing the combined flaps in the bed or holder.
By the rotation of the drill and the descending motion of the slide the
knuckles of the combined flaps in the bed or holder are carried against
the drill and a hole drilled through the knuckles of the two flaps at one
operation. During the operation of the drill the drillings fall from the
drilled hole, and clogging is thereby obviated. After the hole has been
drilled the slide is raised, and the drilled hinge thereby withdrawn from
the drill. The slide is worked by a vertical screw having a rising and
falling motion given to it by a worm wheel, in the bush of which worm
wheel is a screw box into which the screw takes. The screw is prevented
from rotating by a key or feather carried by a handle or lever, the said
key taking into a longitudinal key way in the screw. On the rotation
of the worm wheel the screw rises and falls in the screw box of the
worm wheel, and the slide and parts carried by it are raised and lowered.
After the hole has been drilled and it is wished rapidly to give the back
or return 'motion to the slide, in order to withdraw the hinge from the
drill, the key lever or handle is turned aside, and the key or feather
removed from the key way in the screw. The screw can now be rotated
by means of a hand wheel on its top, and the slide rapidly brought back
without stopping the machine.

page_text: The worm wheel described is driven by a worm on a horizontal shaft,
and the drill is worked by bevil gearing driven by the driving
shaft of the machine. Motion is transmitted from the driving shaft to
the worm shaft by means of a band passing over speed pulleys on the
said shafts.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Chancellor in the Great Seal Patent Office
on the 9th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
CHANCELLOR, of Birmingham, in the County of Warwick, Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

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 Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Henry Chancellor, do hereby
Jaalame the natuan of the ooid Invaation and in what
the
mannau
COMO

page_text: is to be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say:-
My Invention consists of the construction and combinations of parts
herein-after described of machinery for slotting the flaps of hinges, that
is forming or finishing the openings in the knuckles of the said flaps,
and also of machinery for drilling the holes in the knuckles of the said
flaps for receiving the joint pin.
Although my Invention is especially useful for slotting and drilling
hinges, yet it may also be applied to the slotting and drilling of the
parts of other jointed articles, such for example as the joints of banner
scrcons and the horns of castors, and for other like purposes.
I will describe my Invention as applied to the manufacture of hinges.
The machine for slotting the flaps of hinges or for finishing or
dressing the openings in the said flaps consists essentially of one, two, or
more rotating files or cutters under which a travelling bed or table
carrying the hinged flaps to be operated upon slowly passes. The said
files or cutters are mounted upon a horizontal driving shaft to which a
rapid rotatory motion is given. The distance between the files or cutters
is adjusted by filling up dises. The travelling bed or table works upon
a dovetail on an adjustable bed plate, and the upper side of the said bed
or table is of a box form. A series of hinge flaps placed face to
back is so arranged that the slots or openings in the knuckles of the
several flaps are opposite one another or in the same line. The flaps
packed together in this way are clamped in the travelling bed or table
by set screws or otherwise secured, the slots or openings in the several
flaps being opposite the rotating files or cutters. By the rotation of the
files or cutters and the motion of the travelling bed or table the hinge
flaps are brought under the operation of the said files or cutters, and the
slots or openings in the flaps are dressed or finished. Great uniformity
in the size of the openings in the flaps is thus obtained, and the flaps are
ready without further preparation to be fitted together for the drilling
process herein-after described. Instead of dressing or finishing the
openings in the flaps, the openings themselves may be made by the
operation of the rotating files or cutters from solid blanks.
By means of the adjustable bed plate carrying the travelling table and
by set screws, the height of the said table may be adjusted to suit binges
of different sizes.

page_text: The slow motion of the travelling table is taken from the shaft of the
rotating files or cutters by means of worm gearing, a worm wheel
gearing with a toothed rack on the longitudinal side of the bed or table,
giving to it the motion necessary to carry it slowly under the rotating
files or cutters.
The machine for drilling the holes in the knuckles of hinge flaps for
the joint pin of the hingo consists essentially of a vertical drill, point
upwards, having only a rotatory motion and a vertical slide supporting the
hinge flaps to be drilled, the said slide by a descending motion carrying
the knuckles of the flaps against the rotating drill. The slide is
furnished with a bed or holder having a depression in it of a shape to
receive a partly made hinge, the flaps of which have been fitted together
by the engaging of their solid knuckles with the openings in their
respective flaps. The knuckles of the combined flaps are so situated
that they are coincident with the axis of the drill. The combined flaps
are firmly secured in the bed or holder by a jointed cover or lever.
Other means may however be used for securing the combined flaps in
the bed or holder.
By the rotation of the drill and the descending motion of the slide, the
knuckles of the combined flaps in the bed or holder are carried against
the drill, and a hole is drilled through the knuckles of the two flaps at
one or two operations. During the working of the drill the drillings fall
from the drilled hole, and clogging is thereby obviated. After the hole
has been drilled the slide is raised, and the drilled hinge thereby with.
drawn from the drill. The slide is worked by a vertical screw having a
rising and falling motion given to it by a worm wheel, in the bush of
which worm wheel is a screw box into which the screw takes. Tho
screw is prevented from rotating by a key or feather carried by a handle
or lever, the said key taking into a longitudinal key way in the screw.
On the rotation of the worm wheel the screw riscs and falls in the screw
box of the worm wheel, and the slide and parts carried by it are raised and
lowered. After the hole has been drilled and it is wished rapidly to give
the back or return motion to the slide in order to withdraw the hinge
from the drill, the key lever or handle is turned aside, and the key or
feather removed from the key way in the screw; the screw can now bo
rotated by means of a hand wheel on its top, and the slide rapidly
brought back without stopping the machine.

page_text: The worm wheel described is driven by a worm on a horizontal shaft,
and the drill is worked by bevil gearing driven by the driving shaft of
the machine. Motion is transmitted from the driving shaft to the worm
shaft by means of a band passing over speed pulleys on the said shafts.
Having explained the nature of my Invention, I will proceed to
describe with reference to the accompanying Drawings the manner in
which the same is to be performed.
Figure 1 represents in front elevation; Figure 2, the same partly in
longitudinal vertical section; Figure 3, in side elevation; and, Figure 4,
in plan a machine for slotting or dressing or finishing the slots or
openings in the flaps of hinges, the parts of the said machine being con-
structed and combined according to my Invention; Figure 5 represents
in side elevation; Figure 6, in front elevation; Figure 7, in longitudinal
section; Figure 8, in cross section; and, Figure 9, in plan drawn to a
larger scale, the travelling bed or table of the machine in which the
flaps are held while being operated upon. The same letters of reference
indicate the same parts in Figures 1 to 9, both inclusive.
a, a, are the rotating files or cutters mounted on the horizontal
shaft b, the distance between the said cutters being adjusted by packing
or filling up discs c, c, which are fixed by the screw nuts i, i; d is a
packing piece; and d², a coupling. The screw nuts i, i, work respectively
upon right and left handed screws on the shaft b. By means of a
feather and key way on the shaft b and cutters a, a, and the screw
nuts i, i, the said cutters and packing pieces are fixed firmly on the said
shaft b; e is the travelling bed or table having a slow motion under the
rotating files or cutters a, a. The said bed or table works in the dove-
tail on the adjustable bed plate g, the moveable clicek f* of the said
dovetail being pressed against the bevilled edge of the table by the bow
spring hand studs * carried by the said spring. The fixing screws of
the check f permit the said check to have the required play. The bed
or table e is of a box form, and in the said box hinge flaps of the kind
represented in Figure 10 are packed and held.
The construction of the travelling bed or table e will be best under-
stood by referring to the enlarged views, Figures 5, 6, 7, 8, and 9. In
the said table three supporting bars k, l, m, are fixed, the said bars having
in them inclined slots of a size proper to receive the flaps of the hinges.
The said bars k, l, m, can be adjusted at the required distance apart to

page_text: suit different sized hinges. The flaps of the hinges are so placed in the
slots of the bars that the knuckles of the several flaps are opposite one
another or in the same line as represented in Figures 2 and 4, where the
flaps are marked n, n. The supporting bars k, l, m, are fixed in their
places in the bed or table by means of the clamping bar m² acted upon ♬
by the set screws p, p.
When the flaps of the hinges are packed in the
the several flaps are situated
The bed or plate e is capable
from the bed plate of the
table or bed e, the slots or openings in
opposite the rotating files or cutters a, a.
of being readily placed in and removed
machine by a sliding motion.
Several of the tables may be employed so that while the machine is
operating upon the flaps in one table, another table may be packed with
other flaps ready to be placed in the machine.

The height of the travelling bed or table is adjusted to suit hinges of
different sizes by raising or lowering the bed plate 9 by means of the set 1
screws 9, 9, (see Figure 2). The adjustable bed plate y carries the
bearings of the gearing by which the said bed or table e is worked.
Motion is given to the several parts of the machine in the following
manner is the driving shaft; and the driving pulley. On the
shaft is a pinion s which gears with the toothed wheel on the shaft b, 2
carrying the rotating files or cutters a, a. A rotatory motion is thereby
given to the said files or cutters. The slow motion of the travelling bed
or table e is effected by the worm u on the shaft ², gearing with the

on the said shafts and at, as represented in Figure 4.
Instead of driving the shaft x by means of a driving band from the
cutter shaft as represented, the two shafts a and b may be geared
together by toothed gearing. In this arrangement I place the shaft a*
nearer to the shaft as indicated in dotted lines in Figure 4, the said
shafts and being geared together by the toothed wheels 2 and a' as
indicated in dotted lines. The shaft x at the position indicated in
dotted lines transmits its motion to the shaft by a worm and worm
wheel as in the arrangement represented. When the two shafts a

page_text: and o are geared together by toothed gearing as fast described, the speed
pulleys y, y, are omitted.
By the rotation of the files or cutters a, a, and the slow motion of the
travelling bed or table e under them," the hinge flaps in the said table
are operated upon by the said files or cutters, and the slots or openings
in the said flaps are dressed or finished.
The machine described and represented may be employed for forming
the openings in the flaps instead of finishing or dressing the openings
formed in the flaps by the casting process.
Figure 11 represents in front elevation, and Figure 12 in side
elevation a machine for drilling the holes in the knuckles of hinge flaps,
the parts of the said machine being constructed and combined according
to my Invention; Figure 13 represents the same view as Figure 12 after
a hinge has been partly drilled by the machine; Figures 14, 15, 16,
and 17 are portions of the machine as hercin-after describod. The same
letters of reference indicate the same parts in Figures 11 to 17, both
inclusive.
a is the vertical drill, point upwards, and b is the drill spindle working
in bearings and supported in the manner represented. The said drill
has only a rotatory motion, the said motion being given to it by the bevil
gearing c driven by the shaft d and speed pulleys e. The shaft d is the
driving shaft of the machine, and has upon its end the speed driving
pulleys f. The engaged hinge flaps to be drilled are supported in the
vertical slide 9, working upon a dovetail on the fixed framing of the
machine; i is an adjustable dovetail check pressed upon by the bow
spring represented for bearing against the dovetail slide 9. The said
slide g has a descending motion given to it in the manner herein-after
described for the purpose of carrying the knuckles of the flaps fixed in
the said slide against the rotating drill a. Across the slide g is a plate k,
to which a cover or lever is jointed at *. To the plate ka guide
plate is fixed for guiding the drill, the guide plate having in it a
hole, the size of the drill, which when the slide descends advances upon
the drill. The guide plate 1, &, is represented on a larger scale in
Figure 16. In the slide g is a bed or holder m, between which and the
cover or lever the engaged flaps of the hinge are held during the
drilling process. In the said bed m is a groove m in which the knuckles
of the flaps take. After the flaps have been placed in the bed m the

page_text: jointed cover or lever is closed upon the plate k, the packing piece k
inside the said cover bearing with great force upon the flat side of the
engaged hinge flaps, which are thus firmly held in the bed m.
When so
held the knuckles of the flaps are coincident with or in a line with the
guide eye of the plate 1, and with drill a. The jointed cover is
fastened in its place by a lever catch P, the arm of which passes
through an eye on the fixed plate k. The plate k, slide g, lever or
cover, and bed mare represented in horizontal section in Figure 14.
The cyc
on the fixed plate k is capable of adjustment to permit of the
holding of hinges of different thicknesses. This is effected by providing
the said cyc with a screwed shank which passes through the plate k, and
is fixed by lock nuts on either side the said plate k (see Figure 14).
The slide g is worked by the vertical screw n, the bottom of which is con-
nected to the bearing at the top of the slide 9. The said screw n has
a rising and falling motion given to it by means of a screw box in the
bush of the worm wheel 1 (sec Figure 11). The screw is prevented
from rotating by a key or feather 9 carried by the lever or handle r, tho
said key taking into a longitudinal key ways in the spindle of the said
screw. The said lever and key q, r, are best seen in the plan view,
Figure 15.
On the rotation of the worm wheel the screw » rises and
falls in the screw box of the said worm wheel, and the slide g and parts
carried by it are raised and lowered. The worm wheel p is driven by
the worm on the shaft u. Motion is given to the shaft u by a band
from the driving shaft d, the said band working on the speed pulleys e
and, as represented. By the descending motion of the slide 7 and the
rotation of the drill a, the knuckles of the combined flaps in the bed or
holder mare carried against the said drill, and a hole drilled about half
way through the said knuckles, as illustrated in Figure 13. During the
operation of the drill the drillings fall from the drilled hole, and clogging
is thereby prevented. When the drill has passed through about one
half of the knuckles, the screw n ungears itself from the screw box of the
wheel p by the passing of the screw out of the said screw box, and the
slide g and parts carried by it come to rest.
In order to withdraw the partly drilled hinge from off the drill, a back
or retiring motion is given to the slide g. This is effected by first
turning aside the key lever so as to lift the key q from the key ways of
the screw n. The said screw being thus liberated may now be rotated by
the hand wheel n³, and the slide g rapidly brought back without stopping

page_text: the machine. The partly drilled hinge being released from the bed m
it is inverted and refixed in the said bed, and on re-engaging the key q
with the screw n, the slide g again descends and carries the knuckles
against the drill, by which they are completely drilled.
Instead of drilling the knuckles at two operations as described, the
said knuckles may be drilled at one operation. In this case the screw n
is made of such a length that it is not ungeared from the screw box of
the wheel p until the slide 9 has descended far enough for the drill to
have passed completely through the knuckles of the combined flaps of
the hinge.
g
In order to facilitate the re-engaging of the screw n with the screw
box of the wheel p, when the screw is rotated to effect the return or back
motion of the slide, a spring x bears against the said slide and presses
the screw m in contact with its screw box.
The machines described and represented may be used for slotting and
dressing and drilling the joints of other metallic articles besides hinge
flaps, and for other analogous purposes.
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 illustrated,
as the same may be varied without departing from the nature of my In-
vention; but I claim as my Invention,―
