IMPROVEMENTS IN SCARBOROUGH TRUNK LOCKS
Year: 1884

page_text: We, JOSEPH LEGGE, of Little London, Willenhall, in the county of Stafford,
brass lock manufacturer, and WILLIAM SLATER, of Lower Lichfield Street,
Willenhall, aforesaid, brass finisher, do hereby declare the nature of our invention
for IMPROVEMENTS IN SCARBOROUGH TRUNK LOCKS, to be as follows:-
A. Scarborough trunk lock, as ordinarily constructed, has the back-cap soldered
into the front cap of the lock. This is a troublesome operation, and (when the back
cap is of iron, as it usually is) the chemical or spirit employed in connection with
the soldering operation corrodes the surface of the plate and gives it a rusty
appearance; and moreover the back-cap, being usually soldered (as a matter of
convenience) somewhat inwards from the back face of the front cap, instead of
being flush therewith so as to bear against the trunk to which the lock is attached,
may be readily broken out of place by anything striking or pressing the key
heavily whilst inserted in the lock.
Now the object of this invention is to avoid the soldering of the back-cap, and
this is effected, according to this invention, by forming the back-cap with ears, and
producing corresponding sinkings in the inner face of the front cap so that the ears
may lie therein sufficiently for the back cap to be flush with the back of the front
cap. The small bolts for fixing the lock to the trunk pass through the ears and
are made preferably to fit tightly therein so as to retain the back cap in place.
whilst the lock is unfixed. The back-cap thus constructed and fixed cannot possibly
be knocked out of place and the appearance of the front cap is very much improved
by the embossed parts on the outer face which result from the sinkings on the
inner face:

We JOSEPH LEGGE of Little London, Willenhall in the County of Stafford,
Brass Lock Manufacturer, and WILLIAM SLATER, of Lower Lichfield Street,
Willenhall aforesaid, Brass Finisher do hereby declare the nature of our said
Invention for IMPROVEMENTS IN SCARBOROUGH TRUNK LOCKS 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
drawing forming a part of this specification:***
Our invention relates to an improved method of securing the lock in its case.
Hitherto such locks have been secured in their cases by soldering the back-plate of
the lock to the case.
Our invention consists in providing the back-plate of the lock with two or more
ears or projections of any suitable form and in providing the case of the lock with
suitably formed recesses to receive the said ears or projections formed on the
back-plate. Square or other suitably shaped corresponding holes or perforations
are formed in the recesses of the case and in the ears on the back-plate. The bolts
by which the lock is secured to the trunk have their shanks of a form corresponding
to that of the said holes or perforations in the case and back-plate. The said bolts
are stamped through the perforations in the back-plate of the lock thus uniting the
back-plate to the case of the lock.
Figure 1 is a view of the back of one of our improved locks.
Figure 2 is a section of the back-plate and case through the line x. x. of Figure 1,
one bolt being removed.
Like letters indicate like parts in both figures.
The back-plate a of the lock is provided with two or more ears or projections b
of any suitable form. Recesses c₁ are formed in the back of the case c the said
recesses corresponding in number position and form with the ears b on the back-
plate so that when the said back plate is fixed in position the said ears or
projections b fit snugly into the recesses c¹ of the case, the back-plate a and its
ears or projections being flush with the back of the case c. Square or other
suitably shaped holes or perforations d are formed in the recesses of the case and
holes or perforations d¹ are formed in the ears b of the back-plate corresponding in
form and position with those in the recesses of the lock-case. The bolts e by
means of which the lock is secured to the trunk have their shanks e¹ of a form
corresponding with that of the holes or perforations d and d'. The lock is secured
within the case by passing the bolts e through the perforations d of the case and
stamping the shanks e¹ of the bolts e through the perforations d' of the back plate
thus uniting the back-plate of the lock to the case, so that when the lock is
attached to the trunk it is impossible for the back-plate to be forced out of
position.
By our improvements the lock is more readily and cheaply secured in its case, the
outward appearance of the lock-case is improved, and corrosion, from the soldering
of the back plate in position, and the danger of the displacement of the lock in its
case are avoided.

page_text: 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—
First In a Scarborough trunk lock the combination of the back-plate a
having two or more ears or projections b with the lock-case e provided with two or
more recesses c¹ adapted to contain the said ears or projections 6 substantially as
set forth.
or
Second-In a Scarborough trunk lock the combination of the back-plate a,
having two or more ears or projections b and perforations d; the lock-case c
provided with two or more recesses c¹, adapted to contain the said ears
projections b, and with perforations d; and the bolts e having shanks e¹ of
corresponding form to the perforations d and d¹ in the case and back-plate
substantially as set forth.
