GAITERS, PURSES, PORTMANTEAUS, AND OTHER ARTICLES, AND CHUCK USED IN
MANUFACTURING SUCH FASTENERS AND OTHER ARTICLES."

COMPLETE SPECIFICATION filed by the said Edmund Wright at the Office
of the Commissioners of Patents on the 9th June 1879.
"AN IMPROVED
EDMUND WRIGHT, of Birmingham, in the County of Warwick.
FASTENER FOR GLOVES, GAITERS, PURSES, PORTMANTEAUS, AND OTHER ARTICLES,
AND CHUCK USED IN MANUFACTURING SUCH FASTENERS AND OTHER ARTICLES."
The first part of my Invention relates to an improved fastener, consisting of two
parts, the one constructed of a cylindrical shell (or it may be a solid head) fitted
to rotate within another similar "shell," for the purpose of interlocking with a stud
or pin constituting the other part of the fastener whereby great strength, simplicity,
and efficiency of action are secured. The second part of my Invention relates to an
improved lathe chuck in which the several parts of the said studs are securely held
during their manufacture, and in and from which they may be inserted and released
with great ease and rapidity.
In order that the Invention may be more readily understood I have illustrated
it in the accompanying Drawings, and will proceed to describe it with reference
thereto.
The same letters correspond to like parts in each Figure.
Figure 1 is an elevation of the front portion or head of the fastener, and Figures
2 and 3 are elevations of the two parts of which it is composed; Fig. 4 is a central
vertical section of the entire fastener, and Fig. 5 is a horizontal section thereof on
line 1-1, Fig. 4. All these Figures are drawn to an enlarged scale.
A is a covered cylindrical shell (or it may be a solid head) fitted to revolve
freely in an outer cylinder or shell B, the two shells being connected together by
the inner shell A, being slotted or grooved for rather more than a quarter of its
circumference on opposite sides, as seen at a, in which slots or grooves work nibs b
formed by piercing the outer cylinder as shown, and bending down the nibs so
formed into the groove a.
These nibs thus answer the triple purpose of holding
the inner shell in its place in the outer one, as stops to prevent the inner shell from
Di C31

page_text: turning more than the required distance, and as a brake to prevent the inner shell
revolving too freely. The outer shell is provided with a tubular neck C to receive
the stud or pin D shown in Fig. 8, and constituting the other portion of the
fastener. This neck C is passed through one part of the garment or article it is
intended to fasten, and securely fixed therein by being clinched, rivetted, by having
a screw or thread cut on its exterior for a clamping disc to screw upon it, or by
other suitable means. The pin D is attached to the other part of the garment or
article to be fastened in a similar manner.
The pin or stud D has a flat or oblong head d with notches d¹ just beneath, and
the bottom of the inner shell or cylinder A has a corresponding oblong slot e for
the head & to pass through, and on turning the inner shell A. one quarter round
the head & is imprisoned in the slot e by the sides of the latter engaging in the
notches d', as seen in Fig. 5.
.
The portions of the fastener being attached to the two parts of the article to be
fastened, as above mentioned, if the shell A be turned until its slot e coincides in
position with the head d of stud D, the former can be slipped freely onto the
latter and the two secured together by turning the shell A a quarter round, so that
the slot e will be at right angles to the head d as before mentioned. The nibs b
working in the grooves a limit the rotation of the head A and prevent it turning
too easily.
Fig. 6 shows a vertical section on line 2-2, Fig. 7, which shows a horizontal
section on line 3-3, Fig. 6, of a modified arrangement, in which the two parts of
the fastener are locked together by a spring F engaging with a notch dat one
side of the stud D, which in this case is of cylindrical forn with a conical point, as
shown in Fig. 9, the aperture e in the bottom of the inner shell A being likewise
circular to allow of it rotating on the stud D. The spring is preferably of the S
form shown, its two ends having upwardly turned lugs f,f, which enter holes in
the bottom of the shell A. The middle portion of the spring lies partly across the
aperture e, as shown, so that when the stud D is inserted the spring will be pushed
to one side by the conical point of the stud and afterwards fall into the notch d³,
when the inner shell A is turned round to bring the spring opposite said notch.
The motion of the inner shell is limited by the nibs b as before, except that in this
case it should be about 1/3rd of a revolution. On turning it the reverse way the
spring leaves the notch and bears against the plain part of the stud which is then
free to be withdrawn. The top of the shell A may be plain or set with jewels or
other ornaments, as desired.
The lathe chuck, forming the subject of the second part of my Invention, is
shown in longitudinal elevation in Figure 10, in end or face view in Figure 11,
and in central longitudinal section in Figure 12. These Figures are about half size,
but the size of the chuck may be varied according to the work. The chuck consists
of a pair of jaws G, G, jointed on a pivot H, fixed in a cylindrical boss I, screwing
on the lathe mandrel . The jaws a lio and work in longitudinal slots formed in
the boss I, and they are pushed apart by a spiral spring L confined between the
jaws, as shown, so that they project slightly beyond the circumference of the boss I,
and are closed together by a flanged collar M sliding on the boss I, and caused to
turn therewith by a longitudinal feather i on the boss working in a groove in the
collar. The collar is embraced and slid along the boss by a forked lever N received
between the flanges of the collar, said lever being jointed at n to a stud fixed to
the lathe head stock. The jaws are preferably fitted with interchangable faces or
gripping picces g of any desired shape, according to that of the work to be held in
them. They are made of steel and attached by set screws. For round work they
can be bored accurately when in their places. If the work be round like the
studs D, or the other parts of the fastener before described, it is not necessary with
this chuck to stop the lathe to insert and release it.
This chuck may be also made suitable for a hollow spindle lathe by having
separate joints for the jaws G and two springs to force them open, and leaving

page_text: sufficient room between the springs and jaws to form an uninterrupted communi-
cation with the lathe spindle.
Having thus described the nature of the said Invention, and the manner of per-
forming the same, I would have it understood that what I claim as new and desire
to secure by Letters Patent is,―
1st. A fastener, of which the one portion is constructed of a cylindrical "shell"
(or solid head) revolving within another shell, and adapted to thereby interlock
with a notch or notches in the stud constituting the other portion of the fastener,
and to retain or release the said stud as desired, substantially as shown and
described.
2nd. In a fastener constructed as above specified, the inwardly turned nibs made
from the outer shell and working in slots in the inner one, substantially as shown
and described, whereby the inner is retained within the outer shell, and its move-
ment therein limited and regulated.
3rd. In a fastener constructed as above specified, and shown in Figures 6 and 7,
the peculiar S form and arrangement of the spring F in combination with an inner
shell rotating within an outer one, each having a central aperture to receive a
stud having a notch at one side to engage with said spring, substantially as shown
and described.
4th. The improved fastener, constructed, combined, and operating substantially
as shown and described.
5th. The lathe chuck, consisting of a pair of jaws pivoted in a cylindrical boss
and opened by a spring or springs and closed by a sliding collar actuated by a hand
lever, substantially as shown and described.
In witness whereof, 1, the said Edmund Wright, have hereunto set my hand
and seal, this Sixth day of June, in the year of our Lord One thousand
eight hundred and seventy nine.
