IMPROVEMENTS IN LOCKS FOR FASTENING HINGED' LIDS AND OTHER HINGED PARTS, SPECIALLY APPLICABLE FOR SCARBOROUGH TRUNKS
Year: 1884

page_text: We, ISAAC LOFTUS, and SAMUEL MARTIN BAKER, both of 67 Stafford Street,
Willenhall in the County of Stafford, lock manufacturers, do hereby declare the
nature of our invention for, IMPROVEMENTS IN LOCKS FOR FASTENING HINGED'
LIDS AND OTHER HINGED PARTS, SPECIALLY APPLICABLE FOR SCARBOROUGH TRUNKS,
to be as follows:-
The chief object of this invention is to dispense with the usual hasp employed
for hinged lids as a separate part from the lock, and to construct a hasp, in lieu
thereof, in one piece with or rigidly fixed to the lock itself.
According to one modification of this invention, the lock case itself is hinged to
the body of the trunk or similar article to which it is applied, and a hasp is formed
as a projection from the lock and is provided at its upper or outer extremity with
a projection to take over the lid, or to enter an opening in the face of the lid so as
to fasten it. The locking mechanism may be of any convenient construction, and
may be formed self-locking, if desired. A convenient locking mechanism for the
purpose consists of a lever having an opening therethrough which, as the lock is
closed, takes over a stud projecting from a plate fixed against the front of the
trunk or similar article and forming one flap of the hinge of which the lock case
forms the other flap. The stud is provided with a niche into which one edge of
the opening through the lever, aforesaid, springs, and thus locks the lock. The
opposite side also of this stud may be niched so that, if a key is used with a longer
bit than that of the proper key, the opposite side of the opening through the lever
will be moved into such second niche and prevent the lock from being opened.
The outer face of the stud is, in this case, preferably, bevelled to allow of the lock
being simply closed in to lock it. In the case of a Scarborough trunk the hasp is
of course formed to pass around the usual bead at the front of such trunk.
According to another modification of this invention, the lock may be employed
for fastening doors, and other parts hinged to close in a similar manner, either
vertically or horizontally, or in any intermediate position, by forming the hasp
before described simply as a projection to come in front of the door or corresponding
part, when locked. In this case the lock itself is hinged to the door jamb,. or to
other convenient part at the side of the door or similar article to be locked.

page_text: We, ISAAC LOFTUS, and SAMUEL MARTIN BAKER, both of 67 Stafford Street,
Willenball in the County of Stafford, lock manufacturers, do hereby declare the
nature of our invention for IMPROVEMENTS IN LOCKS FOR FASTENING HINGED
LIDS AND OTHER HINGED PARTS, SPECIALLY APPLICABLE FOR SCARBOROUGH TRUNKS,
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) :—
The chief object of this invention is to dispense with the usual hasp employed
for hinged lids of trunks and similar articles as a separate part from the case of
the lock; and to construct such case in one piece with, or rigidly fixed to, a hasp.
One modification of this invention is shewn by figures 1, 2, and 3 of the
accompanying drawings, of which figure 1 is a side elevation of a lock attached to
a Scarborough trunk, the upper part of the front of the body and lower part of
the front of the lid of which is shewn in vertical section. The lock is shewn ]
closed, its position when open being indicated by broken lines. Figure 2 is a plan
of the lock when open; and figure 3 is a sectional plan on line xx of figure 1.
Similar letters of reference in these views indicate corresponding parts.
A is the lid, and B the body of the Scarborough trunk having the usual bead C
in front. D is a plate (shewn partly by a broken line, figure 1) fixed to the body
of the trunk below the bead, by means of screws and nuts a a. E is the lock case,
and F a projection from its upper side forming the hasp. This lock case is hinged
at its lower end to the lower part of the plate D, by the hinge c. The hasp F is
formed so as to pass around the bead C of the trunk, and is furnished at its upper
end with a projection d which enters a corresponding opening in the face of the lid,
to fasten the lid, as shewn by figure 1; or, if preferred, the top of the hasp may be
made to take over the top of the lid. The locking mechanism may be of any con-
venient construction, and may be formed self-locking, if desired. A convenient
locking mechanism for the purpose consists of a stud e, figure 2, projecting from the
plate D, so as to enter a corresponding aperture through the cap-plate of the lock
case, and of a lever or bolt within the case which locks into a niche g in the
stud e.
The outer face of the stud e may be bevelled, if desired, to make the lock
self-locking.
On reference to figures 2 and 3, it will be seen that the plate D is somewhat
shorter than the lock case E. n n are flanges projecting from the inner face of the
lock case, and close in the side edges of the plate D when the trunk is fastened;
the purpose of this special arrangement being simply for appearance.
The cap-plate of the case is of course fixed in the usual manner.
A second modification of this invention is shewn by figures 4 and 5, of which
figure 4 is a front elevation of a lock attached to a Scarborough trunk, sufficiont
only of the trunk being shown to make the application of the invention clear.

page_text: Figure 5 is a side elevation of figure 4, and corresponds to the elevation figure 1,
except that the vertical section through the body and lid is on the centre line
thereof, so as to shew more clearly the holes in the body through which the links,
hereinafter described, project when the lid is fastened.
Similar letters of reference occurring on both these views indicate corresponding
parts.
A, B, and C indicate, as before, the lower part of the lid, the upper part of the
body, and the bead, respectively, of a Scarborough trunk. G is a plate fixed by
the screws and nuts jj to the front of the lid of the trunk. E is the lock case,
and F the hasp formed (as in the first-described modification) as a projection from
the upper part thereof. This hasp is formed to pass around the bead O of the
trunk, and is hinged at its upper end to the plate G by the hinge l. m m are
links projecting from the lock-bolt, which, as the lock is closed, pass through
corresponding holes in the front of the trunk, as shewn; and as the bolt is locked, the
links are moved therewith to take over the edges of the holes through which they
project, and thus firmly hold the hasp from being unhinged. kk etc. are simply
ornamental heads, so as to give the appearance of bolts or rivets.
The lock is
shewn by broken lines, figure 5, in position as if unfastened and raised up.
The application of this invention to locks for hinged lids, and other hinged parts,
generally, will now be readily understood without need for special description.
When, however, the invention is applied to a lock for fastening a door, or other
part hinged to close in a similar manner, either vertically, or horizontally, or in any
intermediate position, it is preferred to use the first-described modification altered
in proportions and details as may be necessary, and dispense with the projection d,
so that the hasp simply comes in front of the door or corresponding part. In this
case, of course, the lock is hinged to the door jamb, or to other convenient part at
the side of the door or similar article to be locked.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. Constructing the lock case of a lock for fastening a hinged lid, or other hinged
part, in one piece with, or rigidly fixed to, a hasp, substantially as herein described
and shewn by the drawings herewith.
2. The modification of a lock case constructed in one piece with, or rigidly fixed
to, a hasp, such combined lock caso and hasp being hinged to the body of a trunk
or other part to which a hinged lid is to be fastened, substantially as and for the
purpose herein described, and shown by figures 1, 2, and 3 of the drawings
herewith.
3. The modification of a lock case constructed in one piece with, or rigidly fixed
to, a hasp, such combined lock caso and hasp being hinged to the hinged lid of a
trunk or other hinged part to be fastened, substantially as and for the purpose
herein described, and shewn by figures 4 and 5 of the drawings herewith.
