COMPLETE SPECIFICATION.
Rim Locks.
I, WARREN H. TAYLOR, a citizen of the United States, and residing at
26 Clinton Avenue in the City of Stamford, County of Fairfield, and State of
Connecticut, United States of America, Superintendent in the Lock Department
of The Yale & Towne Manufacturing Company, in said City of Stamford, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
My invention has for its object to produce a rim lock which shall have an
improved method of attachment to a door which will be more secure, and at the
same time, more convenient than the ordinary means, and invisible.
I have shown my invention as applied to that form of lock where the tumbler
mechanism is contained in a separate tumbler case or escutcheon which is attached
But while
to the door by being screwed to an attaching plate of the lock case.
my invention is very well adapted to this type of lock it should be understood that
it is not by any means confined to it, because many of its advantages may be
obtained in any type of lock by using a fastening plate which is secured to the
door in any convenient manner and fitted for engagement with the lock case.
My invention will be fully understood upon reference to the accompanying
drawing in which :-
. Figure 1 is a view of a lock and its keeper attached to a door by means of my
present invention.
Figure 2 is a section of the same on the line 2-2 Figs. 1, 3 and 4.
Figure 3 is a section on the line 3-3, Figs. 1, 2 and 4.
Figure 4 is a section on the line 4-4 Figs. 2 and 3, and
Figure 5 is a detail sectional view on the line 5-5 Fig. 4 showing the manner
of securing the spring abutment bar which holds the mechanism in place in the
lock case.
1 represents the lock case and 2 the keeper.
The keeper is secured by a screw 3 passing through an internal screw-hole 3*
into the jamb or door or other part to which the keeper is to be connected, and
said keeper may be additionally secured by means of a screw which passes through
a projection from said keeper into the edge of the door. This additional screw is
not necessary in all cases."
8 represents a plate which in the form of lock shown, serves as a back-plate for
holding the escutcheon in place on the front of the door, this being accomplished
by the screws 10 as shown in Fig. 2. The plate 8 also serves as an attaching
means for securing the case to the door. This is accomplished by forming the
lugs 9 on the plate and lugs 11 on the case which, when the case is in proper
position, are in engagement with each other. The case is further secured by
means of screws 7 which pass through suitable openings in the edge-plate 6 and
into the door. The manner of attaching the case is very simple it only being
necessary to place the case in proper position and then move it in a direction so as
to have the lugs 9 and 11 engage and have the plate 6 fit against the edge of the
door.
It will be understood that when the form of lock shown in the drawings is used
it is necessary to provide a means for holding the mechanism in the case. This I

page_text: accomplish by forming projections.125on the spring abutment bar 13 which fit in
notches 14 formed in the projections 15 of the lock case against which, in the
ordinary construction of locks of this class, the abutment bar 13 bears. Thus it
will be seen that when the case contains the locking mechanism and this form of
attaching means is used, the parts will be held in their proper positions. This
method of holding the operative parts in a case when the back is taken off, or if
there should be no back, will be found. useful, not only in cases where an attaching
plate is used, as provided in this device but also in all other cases where the back for
holding the parts in place is removed or is not used. For instance, in some cases
it is desirable to remove the back, and for reversing the latch bolt.
It will be observed that while the particular form of lock shown is especially
adapted for attachment by means of my present invention, the invention is by no
means inseparable therefrom, as the attaching part may be secured to the door in
any suitable way other than by forming it with the plate 8 which constitutes the
back of the lock, or the plate 8 forming the back of the lock may be secured in
any way other than by means of screws connecting the back to the external
escutcheon carrying the tumbler mechanism, and the locking mechanism may also
be carried by. the plate in which case the means for holding the mechanism in
proper position in the case above referred to may be dispensed with. I therefore
wish it to be understood that I do not limit myself to any particular form of parts
nor to any particular tumbler or locking mechanism, as this is not material to my
invention although there is an advantageous combination between the parts when
connected in the manner shown.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner. the same. is to be performed, I declare that what I
claim is :
1. The combination of an attaching plate, which is independently attached to
the door, a lock case fitted for engagement therewith, and suitable means for
holding the mechanism contained in the lock case in place consisting of a spring
abutment bar provided with projections which fit in notches formed in the lock
case, so that the case can be applied without disturbing the mechanism, as
"set forth.
2. The combination of an escutcheon inserted from the outside an attaching
plate located on the inside and secured to said escutcheon so as to bind both
securely to the door, and a lock case having projections or depressions which are
adapted to be slid into engagement with corresponding depressions or projections
upon said attaching plate, and suitable means for securing it in engaged position,
'as explained.
3. In a lock, the combination of an attaching plate which is independently
fastened to the door, an escutcheon containing the tumbler mechanism which is
attached to said plate and which extends to the exterior of the door on one side,
and the case containing the latching or locking mechanism which is attached: to
said plate upon the other side of the door, substantially as described.
4. In a lock, an attaching plate which is independently fastened to a door in
combination with the lock case, said plate being provided with lugs and said case
being provided with means adapted to be slid into engagement with the lugs on
the plate, so that when the case is placed over the attaching plate, said plate and
said means of engagement between the case and plate are inaccessible and
invisible, substantially as described.
5. In a lock, the combination of an attaching plate provided with. lugs,
independently fastened to the door and in combination with a lock case also
provided with lugs which are adapted to be slid into engagement with the lugs
on the plate, said case being provided with means for securing it to the edge of
the door, so that when secured in place the fastening plate and the means

page_text: whereby it is secured to the door and the means whereby the lock case is also
held in place are all inaccessible and invisible when the door is closed, substantially
as shown and described.
