Year: 1884

page_text: I, SAMUEL LLOYD, junior, of Drayton Works, Sidney Street Wolverhampton,
in the County of Stafford, Japanner, do hereby declare the nature of my inven-
tion for, AN IMPROVED FASTENING FOR HINGED LIDS, SPECIALLY ADAPTED FOR
TRAVELLING TRUNKS, AND CASH, DEED, AND OTHER BOXES, to be as follows:-
case fixed
A fastening constructed according to this invention is carried within
inside the front of a trunk (or other article having a hinged lid), or within a
moulding on such front. Two links are fixed to the lid so that their lower ends
pass down through holes in the top edge of the case when the lid is closed. Bolts
are constructed to slide within the case, namely, one for each of the links. These
bolts are moved to and fro by means of a central disc-plate carried upon a stud
within the case, and having crank pins or studs thereon, motion being conveyed
from the disc-plate to the bolts by means of a connecting rod pivoted to the studs
upon the disc-plate and to studs upon the bolts. The studs project upon the
disc-plate backwards therefrom; and a central boss at the back of the plate is
bored to turn upon the stud within the case. The depth of this boss is regulated
to bring the disc-plate against the inside of the front of the trunk, or the moulding
thereon; and a flat thumb-piece, having its plane at right angles to that of the
disc-plate, and being itself of a length shorter than the diameter of the disc-plate,
stands forward through a circular hole in the front of the trunk (or other article
having a hinged lid) or of the moulding thereon. The disc-plate is thus prevented
from moving backwards or forwards upon its stud, but may be moved axially by
means of the projecting thumb piece. As it is turned in one direction the two
bolta, aforesaid, are drawn back and the links may be raised from the case and the
lid consequently opened; and when the disc is turned in the opposite direction the
bolts are shot out, and, if the lid is closed, these bolts engage with the links and
fasten the lid. The thumb-piece on the disc-plate is arranged to be in a vertical
position when the bolts are shot out; and the disc may be prevented from being
turned when in this position by means of a hinged hasp having a slot hole
therethrough to receive such thumb-piece when the hasp is closed down, or having
a narrow hollow cap to close completely down over the thumb piece. When the
hasp is closed down it may be fastened by means of a lock in the usual manner, or
by means of a small padlock passing through the projecting part of the thumb
piece or through such thumb-piece and the cap covering it; or the disc may be
locked in any suitable manner when the bolts are shot out.

I, SAMUEL LLOYD, Junior, of Drayton Works, Sidney Street, Wolverhampton,
in the County of Stafford, Japanner, do hereby declare the nature of my inven-
tion for AN IMPROVED FASTENING FOR HINGED LIDS SPECIALLY ADAPTED FOR
TRAVELLING TRUNKS AND CASH, DEED, AND OTHER BOXES and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement reference being had to the accompanying drawings and
the letters of reference marked thereon (that is to say) :-
My improved fastening for hinged lids is illustrated, by the accompanying
drawings, in its application to a sheet metal travelling trunk, and I will proceed
to describe the invention with reference to this special application after which its
adaptation for the purposes of hinged lids generally will be sufficiently obvious
without need for further description or illustration.
Figure 1 is a front view of my improved fastening, with the sheet metal forming
the front of the body of the trunk supposed to be removed; so as to shew the
mechanism. Figure 2 is a sectional plan of figure 1 taken on a line immediately
beneath the top of the moulding or case in which the mechanism is contained; and
figure 3 (placed for convenience of illustration in the place of a broken-away part
of figure 1) is a section taken on line" of figure 1, excepting that the lock
hereinafter described is shewn in side elevation and not in section. The same
letters of reference occurring upon two or more of these views indicate corre-
sponding parts. A is the top of a moulding running around the-upper part of the
body of the trunk on to which the lid B closes down. C is a vertical part forming
the top edge of the body of the trunk. D D is a plate carrying the mechanism ;
this plate is fixed along its upper side to the part C of the trunk and along its
lower side to the front of the trunk by means of rivets a a etc. E E are links
riveted or otherwise fixed inside the front edge of the lid so that their lower ends
pass down through holes formed therefor in the shoulder A, when the lid is closed.
FF' are bolts carried within guides G G¹. The back ends or tails of these bolts
are connected by means of rods to crank pins or studs b b carried in lugs upon a
central disc or plug J capable of turning upon a stud K. The disc or plug J is
hollow from the front face, and is provided with a cross bar L by which it may be
readily turned upon inserting the thumb and fore-finger within the hollow of the
disc. M is a plate riveted to the inside of the plate D; and N is a plate distanced
off from the plate M by means of the distance-pieces c c and part d, which latter
forms the fore-plate to the lock O, presently to be described. A rivet is formed at
each end of the distance-pieces c c, and one or more rivets are formed at the front
and back edges of the part d, by which the plates M and N are securely held
together. e is a collar around the disc J and bears around the inside of the plate N,
and fis a collar or washer at the back of the disc J and bears against the plate M,
so that the disc J is held in position between the plates M and N. g is a part of
the disc J passing through the plate N so as to assist in keeping the disc or plug J
in its proper central position and also. to produce a neat appearance and finish,
P¹ is a fillet upon the plate N, projecting through the front of the trunk so as to
assist in keeping the plate N in its proper central position and. to give a neat
appearance and finish.
It will be seen that upon turning the disc J in the direction of the arrow h, the
rods HH will be drawn backwards or towards the centre and thus draw the
bolts FF back from the links E E and allow the lid to be opened. Upon turning
the disc in the opposite direction, the bolts F F will be pushed outwards again to
retain the links E E, if the lid is closed; but in the arrangement illustrated the

page_text: shooting out of the bolts is made self-acting by means of a spiral spring around a
shank or pin Q upon the bolt F. A similar spring may be used for each of the
bolts, if desired, but one is sufficient for the purpose. As the lid is closed down,
the inclined faces ji on the links, striking against correspondingly inclined faces on
the bolts, force back the bolts until the lid is closed, when the bolts are forced
forwards again by the spring or springs to fasten the links. When it is desired to
open the lid the disc is simply turned in the direction of the arrow has before-
described.
S is a projection upon the disc J, and T a projection or stop upon the plate M, or
upon the part d, for the purpose of forming a stop to the movement of the disc J
in the direction in which it is moved by the spring P. O is a lock fitted with any
ordinary or convenient locking mechanism for shooting out and drawing back a
lock-bolt R. The fastening is locked by simply shooting out such bolt on the side
of the part S, as shewn by figure 1. V is a slotted opening through the tail of the
bolt F to allow clearance for one side of the spring. The end of the spring is
passed through a hole in the end of the guide G, as shewn at k, so as to keep the
spring and shank Q in position sideways. 7 is a stud projecting from the inside of
the guide Gin front of the tail of the bolt F¹ to keep such bolt in position
sideways. U is a convenient form of handle by which to lift the lid.
The fastening above described is very convenient in use, and allows of securely
fastening the lid against its being accidentally opened, without the necessity for
locking it, and has no projection in front of the trunk except for the heads of
screws or rivets and for any parts which may be projected for the sake of ornament
or appearance.
Two bolts F F and links E E are shewn in the illustration, and are very much
preferred, but of course one bolt and link only may be used if desired, such being
placed preferably central with the trunk and the disc or plug arranged below and
geared with lever mechanism to actuate the bolt, or the disc or plug may in such
case be arranged at one side.
The application of this invention for the purposes of fastening hinged lids of
cash, deed, and other boxes, and hinged lids generally, will now be sufficiently
obvious without need for further description or illustration.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The improved fastening for hinged lids specially adapted for travelling
trunks, and cash, deed, and other boxes, according to which a disc or plug carried
by a part to which a hinged lid is to be fastened, is turned on its axis to give
motion by means of suitable rods or connections to a bolt or bolts engaging with a
link or links fixed to such lid, substantially as and for the purpose herein described
and shewn by the drawings.
2. The improved fastening for hinged lids specially adapted for travelling
trunks, and cash, deed, and other boxes, consisting of the disc or plug J,
rods HH (or one of them) and the bolts F F and links E E (or one of such
bolts and links) substantially as and for the purpose herein described and shewn
by the drawings.
Dated this seventh day of November 1884.
