page_text: LETTERS PATENT to Charles Frank Conway Morris and Frank Howard
Bennett, both of Number 175, Blackfriars. Road, London, S.E., for an
Invention of "IMPROVED APPARATUS TO BE USED AS A MEANS FOR
READILY AND INSTANTLY SLIPPING, RELEASING, DETACHING, DISENGAGING,
OR UNCOUPLING."
COMPLETE SPECIFICATION filed by the said Charles Frank Conway Morris
and Frank Howard Bennett at the Office of the Commissioners of Patents
on the 11th November 1881.
CHARLES FRANK CONWAY MORRIS and FRANK HOWARD BENNETT, both of
Number 175, Blackfriars Road, London, S.E. "IMPROVED APPARATUS TO BE
USED AS A MEANS FOR READILY AND INSTANTLY SLIPPING, RELEASING,
DETACHING, DISENGAGING, OR UNCOUPLING."
Our Invention consists in improvements upon the arrangements of apparatus and
parts for the above mentioned purpose, described and claimed in the Patent of the
said Charles Frank Conway Morris in his Specification Number 1389, bearing
date the Eighth day of April 1879, and with especial reference to that portion
whereof wherein is described the "slip" itself, and reference made to some of its
special applications (as distinguished from its "combination" application for the
purpose of skidding wheels); as also in improvements upon the joint Invention of
the said Charles Frank Conway Morris and Frank Howard Bennett, bearing date
the Twenty second day of March 1881, numbered 1265.
According to the present Invention we embody the following essential features
in applying our said Invention to such and similar uses as those indicated
in the Provisional Specification of the said Charles Frank Conway Morris,
Number 1389/79, lives 18 to 23 (printed copy of Specification), and as also indi-
cated in our joint Invention, Number 1265, dated the Twenty second day of March,
One thousand eight hundred and eighty one, that is to say, under one arrangement
of "slip" according to our present Invention the two separate levers or pivotted
side and cross pieces, shewn in the Drawing accompanying Specification,

page_text: Number 1389/79, are now combined as one member or part, with an eye formed
in the locking part thereof, taking into a spring locking and unlocking bolt
or pin, with ring releasing attachment or suitable mechanical equivalent therefor ;
and according to another and more simple arrangement of our said Invention, in
addition to the two levers before mentioned being combined in one, this combined
limb or member (being the locking and unlocking or releasing portion thereof) is
also caused to form one half of the actual framing when the "slip" is " locked."
In each of the said arrangements according to our present Invention, as in our
previous joint Invention (Number 1265/81), a distinctive feature is that of the
plane of the centre of the pivot at the lower end of the "slipping" apparatus being
out of the plane of the centre of the releasing spring pin or bolt at the head or top
of the apparatus. We find that this is indispensably necessary to obviate the
adoption of the compound arrangement of levers and moving parts under the Patent
of Charles Frank Conway Morris, hereinbefore referred to, and of other compound
arrangements used in other apparatus to be used for similar purposes to those for
which the apparatus according to our present Invention is intended to be employed.
And we have stated in the Specification of our joint Invention, Number 1265/81,
that the extent of the difference between the lines of centres to bo a nominal one
of, say, of an inch; but according to our present Invention, so as to ensure the
production of an apparatus to be relied upon under all circumstances when subjected
to any great strain or pull required to be "slipped," disengaged, or released from
the said apparatus, we make the releasing pin or bolt of a tapered or slightly
conical shape, and which takes into a corresponding tapered recess, cavity, or hole
at the head or top of the apparatus. This arrangement is shewn at Figure 13,
Sheet-2..

In the accompanying two Sheets of Drawings the same letters of reference denote
like or corresponding parts throughout the several views. Referring to Sheet 1,
Figures 1, 2, and 3 are merely given in outline, and are included for the purpose of
more clearly defining the distinctive features of the present Invention, as compared
with the two Inventions hereinbefore referred to; Figures 4 and 5 illustrate the
slipping apparatus according to our Invention as it appears when "locked" or
secured, and Figure 6 is a view corresponding with Figure 4, but shewing the
apparatus unlocked or unsecured, or "slipped;" A, A', is the enclosing framing;
B, B', the moveable member or locking and unlocking part pivotted at C. The
portion A of A, A¹, is recessed sufficiently (as indicated by the dotted line a, in
Figure 6) to allow of the part B of B, B', taking thereinto when the apparatus
is "locked;" the shorter portion A' of the enclosing framing is slotted right
through, as shewn; D is the eye or hole formed in the longer part B of B, B¹.
The arrangement of spring locking and unlocking pin or bolt is shewn at E,
and (which, as being adapted for ordinary strains, is here shewn as a parallel
sided pin or bolt) e is an eye or hole formed in the said pin or bolt for passing
therethrough a ring and line, chain or cord, as the operating or other releasing
attachment. The upper end or head F of the apparatus is provided with an
eye f, for shackle or other suitable connection, according to the purpose to which
the said apparatus is applied. The limb or member B of B, B', is formed with a
slight recess at d, to facilitate the operations of locking and unlocking at the point
where the spring pin E takes into the eye or hole D. The modus operandi. will
be readily understood on reference to the accompanying Drawings, as on the spring
pin E being pulled outwardly at c, the said pin is caused to leave the eye D.in B,
and the chain, hook, or other attachment previously held securely at B' is
immediately freed or released from the apparatus. Figures 7, 8, and 9 illustrate an
arrangement of " slipping" apparatus according to our present Invention, as
specially designed for contractors' "tipping waggons," the head F of the apparatus
being formed as a cross piece with recessed portion or jaw for attachment to the
spring bar." Figures 10 and 11 illustrate (to a reduced scale) the modification of
our said Invention bereinbefore referred to, wherein the locking and unlocking or
releasing portion of the apparatus is also caused to form one half of the actual
"

page_text: framing when the apparatus is "locked;" this applies also to the arrangement shewn
at Figures 7, 8, and 9, referring to which last named illustrations it will be noticed
that provision is made at E' whereby the releasing arrangement may be applied to
either the right or left hand side of the apparatus. The modifications of our said
Invention as shewn, Figures 4 to 6 and 10 to 11, are applied with great advantage
to vehicles and vehicular traffic when used as collar chain slips, so as to afford a
ready means of relieving the collar chains of horses when fallen down, and as a
detaching arrangement for harness generally; as also for lowering boats and for a
variety of purposes on board ship, such, for instance, as the working of the sails,
and so forth, and other marine uses. In connection with railway traffic, the
modifications of our Invention last referred to may be used with great advantage
for "slipping" railway carriages; the said modifications may also be adopted with
great advantage for the cages in mines, and as a detaching gear in connection with
cranes, and for similar uses. The modifications shewn at Figures 10 and 11
specially illustrate an adaptation of our said Invention as designed for a "pole
chain slip," and though we have therein shewn the head F of the same, as adapted
for an independent attachment, it may be modified so as to form an actual part of the
pole lead itself. Figure 12, Sheet 2, is a detached view of the taper releasing spring
pin or bolt hereinbefore referred to, and Figure 13, Sheet 2, shews an arrangement
of our apparatus in which the moveable part B is so formed that when in use it
assumes the form or shape of the ring as used at present in connection with the
harness of carriages and other vehicles, and which is adaptable also when pole
chains or straps are used; this arrangement ensures also that when the apparatus
is released or un-locked," the said chain or the straps in harnessing will readily
glide away from the moveable momber or drop piece B, without any chance of
fouling or of injury to the straps or chain.

Having now described and illustrated our said Invention, we wish it to be
understood that we do not confine ourselves to the exact details herein shewn and
described, as modifications may be made therein without departing from the main
or essential features of our said Invention, and similarly, though we have herein
recited some of the purposes to which our said Invention may be applied, we do
not confine ourselves thereto, but what we claim is,--
First. The construction and arrangement generally of the apparatus, substantially
as herein described and shewn in the accompanying Drawings, and irrespective of
the purposes or of applications to which the said apparatus in its various modifi-
cations according to this our said Invention may be put.
Second. The special feature hereinbefore referred to of the centre of the pivot
at C (at the lower end of the apparatus) being out of the centre of the spring pin
or bolt E (at the top of the apparatus), so that the strain is actually thrown upon
the said pivot at C, and thereby taking the strain off the spring pin or bolt E at
the top of the apparatus.
In witness whereof, we, the said Charles Frank Conway Morris and Frank
Howard Bennett, have hereunto set our hands and seals, this Tenth day
of November, in the year of our Lord One thousand eight hundred and
