I, SALOMON SIMSON of Mettmann in the Kingdom of Prussia and Empire of Germany,
Manufacturer, do hereby declare the nature of this invention, to be as follows:-
This invention has for its chief purpose to produce a lock, in which the distance between
the key hole and the face plate may be varied so that locks made in one size may suit a
variety of purposes. This object is attained by disconnecting the face plate from the
body of the lock and forming it as a separate part and by enabling the bolt to be
extended or shortened according to the desired distance from the key hole to the
mortise board. For this purpose the lock casing is furnished in its upper and lower
extremity with guides, against which slide slotted bars, fastened at their outer ends
to the face plate. Through the slots pass set screws, by means of which the bars may
be fixed at any desired position relative to the guides so that the face plate may be
fixed within relatively large limits at the desired distance from the key hole.
The bolt must also admit of being correspondingly extended. For this purpose the
said bolt is made in two parts sliding over each other and enabled to be fixed together
at the desired position by a set screw. The cover plate may also be provided with a
slit, so as to allow the said set screw to be reached and therefore the bolt extended or
shortened, without requiring any part of the lock to be opened.
The face plate need not be fixed in the manner described, but may be left loose from
the lock and only screwed to the door or other object, the lock being also screwed, or
the set screw fixing its position may be set so as to clamp the guide bars in the casing
of the lock.
In "cut locks," that is to say those having a back plate which is recessed into the
wood so as to lie flush with the surface a second back lock plate is employed. The
lock mechanism is mounted in a case which may be fixed at the required position on
the back lock plate.
Also for lengthening the bolt, that is to say for moving and adjusting the two parts
thereof I may make use of a screw spindle guided in the one part and operating the
other, or I may use any convenient means.

page_text: 1,SALOMON SIMSON of Mettmann, in the Kingdom of Prussia and Empire of Germany,
Manufacturer, do hereby declare the nature of my invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention relates to locks and it consists in rendering the face plate from which
the bolt is protruded, together with said bolt, adjustable to or from the lock operating
mechanism, so that the said face plate may be fixed at a convenient distance (within
certain limits) from the operating mechanism, without impairing the operation of the
bolt for locking.
For this purpose, the face plate, is a separate part from the body of the lock, but
may be contrived with devices or means by which it may be guided thereon or thereby,
and to be fixed, if desired in the position to which it is adjusted. The bolt is also
made adjustable in length.
The accompanying drawings illustrate methods of performing this invention.
Fig. 1 is a section of a mortise lock having one bolt only-showing a method of
fixing the face plate a at the desired distance from the body of the lock, also of
rendering the length of the bolt adjustable.
Fig. 2 shows a lock on another system having adjustable bolt and independent
face plate, being guides for the bolt.
Fig. 3 is a modification of the lock shown in Fig. 1.
Fig. 4 is a cross section of the last, with bolt and mechanism removed.
Fig. 5 illustrates an adjustable slam and bolt lock.
Fig. 5 illustrates in cross section the method of rendering the slam bolt adjustable
in length.
Fig. 6 illustrates the application of the invention to case locks.
Fig. 7 shows a modification for rendering a slam lock bolt or other bolt adjustable
in length.
Referring to Fig. 1-In mortise locks, in order to enable the face plate a to be
secured in the position given to it with regard to the body of the lock, the said face
plate is provided with one or more arms a guided upon or by cross bars a fixed in
the body of the lock. Longitudinal slots a are cut in said arms, and through said
slots engage the set screws a' screwed into the bar or bars a nearest to the face of.
the lock. By partially loosening said screws a' the arms a' may be moved and the
face plate a set at the required distance from the body of the lock, it being thero fixed
by fastening down said screws.
The bolt c is rendered adjustable in length by being formed in two parts sliding upon
each other, the one part having a slot i through which a set screw engages capable of
a

page_text: securing the first part in the desired position to the second.
To enable this set screw
to be reached without opening any parts of the lock, the lock plate or case is provided
with a slit as illustrated in dotted lines in Fig. 1.
In place of providing slots in the arms a¹ the latter may be of sufficient width to be
held by clamping between the plates s and c of the lock, the latter being held by four
or more screws a³ (Figs. 3 and 4).
Furthermore the face plate may be screwed to the door or other object, the lock
body being also screwed thereto. In such case the arms a' or the fixing thereof may
bo omitted.
In the mortise slam lock shown by Fig. V the clamping as aforesaid is applied, both
by means of screws a', and screws a³.
The slam bolt is formed in two parts 6, 61, the part 6 forming the nose of the
bolt being socketted to slide over the part 6 (Fig. Va). In the face of said part b
are a series of recesses 1, 2, 3 in which engages the pin 60 screwed through the
wall of the nose b.
Fig. VII shows also a construction for rendering the slam or other bolt easily
adjustable and with great exactness, without requiring the lock plate to be opened.
The nose of the bolt carries a slotted extension into which engages the block 63
forming part with the rear portion 6 of the bolt.
It is further guided by the cheeks 6 on said rear portion of the bolt. A screw
spindle is journalled in the rear portion of the bolt but incapable of longitudinal
movement therein, the said spindle being provided with a suitable head so that it
may be turned, from outside by means of a suitable tool. The spindle passes through
the rear part of the aforesaid rearward extension of the nose of the bolt, whilst its
front end is journalled in the block 63 beforementioned. The spindle may be turned
and the nose of the bolt can be set forward or backward thereby without requiring
the lock to be opened.
In case-locks the back lock plate is formed in one part with the face plate a and
the lock mechanism is arranged on a plate S which may be fixed at the required position
on the back lock plate, the said plate S has slits S' through which set screws S' pass
into the lower case plate a, so as to connect the latter rigidly with the lock plate S in
the position given to the latter. The bolt is made adjustable as aforesaid.
Locks made in the described manner in one size can therefore be adjusted to replace
locks of different sizes. The above described arrangements may be employed for all
kinds of locks.
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. In a lock the combination with a lock mechanism having an extensible bolt or
bolts of a face or mortise plate as a part, separate from said mechanism.
2. In locks the combination with a lock mechanism of a face or mortise plate a,
connected to said lock mechanism by arms a' adapted to be secured with regard to said
lock mechanism substantially as set forth.
3. In a lock the combination with a lock mechanism of a face or mortise plate a
connected to said lock mechanism by slotted arms a' adapted to be secured by set
screws passing through the slots in said arms substantially as set forth.
4. In a lock the combination with a casing containing lock mechanism and
comprising plates s and c of a face or mortise plate a having arms a' a' adapted to be
secured between said plates s and c substantially as set forth.
5. In a lock the combination with a lock mechanism of a face or mortise plate
independent of said lock mechanism; said lock having guides u substantially as and
for the purpose set forth.
6. In a case lock a slotted plate carrying the lock mechanism said plate adapted to
be displaced upon the case plate and secured thereto by set screws.
7. In a lock, a bolt composed of two parts adapted to be extended with regard to
each other and secured together.

page_text: 8. An extensible bolt composed of two parts adapted to be extended with regard
to each other, one part being slotted with a set screw engaging through said slot
substantially as and for the purpose set forth.
9. A bolt composed of extensible parts one part being capable of sliding within the
other said inner part having a series of recessed, and said outer part having a set
screw adapted to engage into said recesses.
10. The combination with a bolt composed of two extensible parts, of a screw
spindle adapted to operate said parts substantially as and for the purpose set forth.
