page_text: LETTERS PATENT to William Harrison, of Sheffield, in the County of York,
for an Invention of "IMPROVEMENTS IN OR CONNECTED WITH THE CON-
STRUCTION OF LOCKS, HANDLES, AND METHOD OF FIXING SUCH HANDLES TO
DOORS AND DRAWERS."
PROVISIONAL SPECIFICATION left by the said William Harrison at the
Office of the Commissioners of Patents on the 20th April 1880.
"
WILLIAM HARRISON, of Sheffield, in the County of York. IMPROVEMENTS IN
OR CONNECTED WITH THE CONSTRUCTION OF LOCKS, HANDLES, AND METHOD OF
FIXING SUCH HANDLES TO DOORS AND DRAWERS."
According to the first part of this Invention I clongate the "follower" of the
lock, so that it may extend through or nearly through the door or drawer to which
it is to bo attached. This may be done either by screwing a tube into or onto the
'follower," or the "follower" may be made extended in the first instance. For
mortise locks I prefer to adopt the former method for sake of convenience when
fixing the lock in a door or drawer.
"
The second part of this Invention relates to a method of constructing and fixing
handles to doors or drawers. To the back of the handle and immediately behind
the "rose" I attach a circular plate capable of revolving on the said handle; this
plate has holes therein near its outer edge in order to attach it to the door or
drawer. Now, according to this Invention, the "rose" (which is also fitted so as
to revolvo on the handle) has a hole or opening near its outer edge so that upon
turning the "rose" round the hole or opening therein shall come opposite to one
or other of the holes in the aforesaid plate, and thus enable a screw to be screwed
into each hole in the plate and thus bo fastened to the door or drawer. The holo
or opening in the "rose" must be sufficiently large to allow the head of the screw
to pass through same, and be flush with the surface of the aforosaid plate, so that
the "rose" may pass over it when being turned round to insert another screw.

"IMPROVEMENTS IN
OR CONNECTED WITH THE CONSTRUCTION OF LOCKS, HANDLES, AND METHOD OF
FIXING SUCH HANDLES TO DOORS AND DRAWERS."
According to the first part of this Invention I elongate the "follower" of the
lock so that it may extend through or nearly through the door or drawer to which
it is to be attached. This may be done either by screwing a tube into or on to
the "follower," or the "follower may be made extended in the first instance.
For mortice locks I prefer to adopt the former method for sake of convenience

The second part of this Invention relates to a method of constructing and fixing
handles to doors or drawers. To the back of the handle and immediately behind
the rose is a circular plate; this plate has boles therein near its outer edge in order
to attach it to the door or drawer.
Now, according to this part of my Invention, the rose (which is fitted so as to
revolve on the Landle) has a hole or opening near its outer edge, so that upon
turning the "rose" round the hole or opening therein shall come opposite to one or
other of the holes in the aforesaid plate, and thus enable a screw to be screwed
into each hole in the plate and thus be fastened to the door or drawer. The hole
or opening in the "rose" must be sufficiently large to allow the head of the screw to
pass through same, and be flush with the surface of the aforesaid plate, so that the
rose may pass over it when being turned round to insert another screw. And in
order to explain my said Invention more fully I will now proceed to describe the
same with reference to the accompanying Drawing.
"
"
Figure 1 is a cross section of a rim lock, shewing my improvements adapted
thereto and as it would appear when fitted to a door; a is the lock; b, the
follower extended as indicated by c. This follower is provided with internal
screw threads, as shewn, and the end b has a square hole to receive the square
spindle or cotter pin d, and is also provided with internal screw threads for a short
distance for the reception of the handle or knob e. This internally screwed and
extended partc of the follower b is for the reception of the screw f fixed to
the handle or knob g, said screw having a square hole through it corresponding
with the spindle or cotter pin d.
The lock a is with extended follower band handle e screwed to the the door a¹
the extended portion c of the follower passing through a hole in the door the
screw (with its knob g) is screwed into the extended part c of the follower b,
so as to adjust it to the thickness of the door; after this has been effected the
square spindle or cotter pin d is inserted through the square holes in the
follower band screw f, thus locking both handles to the follower b. After tho
insertion of the spindle d as above the hole in the knob or handle e is closed
by means of the screw plug h.
Figure 2 is a modification of the above, and in this case the follower 6 has a
loose extension piece c, having a square projection c' on one end thereof. This
square end c' fits into a corresponding recess formed in the follower b. An end
view of this extension piece c and projection c¹ is shewn detached at Figure 3. In
this case the lock is not first attached to the door, as in the former case, but is
attached in the following manner :-The square spindle or cotter pin d, which is
fixed to the knob or handle g by means of a screw x, is passed through the hole
in the door, the said spindle having a screw-thread cut throughout its entire length
on the angles thereof, the loose extension part c of the follower travels thereon,
and is screwed so far up the bar d until the disc c abuts against one side of the
door, thus adjusting the follower to the thickness of the said door. The lock a

page_text: with knob e screwed up to its position is then placed on the square spindle d,
the latter passing through the follower b. The square recess in the follower b
will receive the square projection c' of the loose extension piece of the follower,
whereby the locking of the handles and a firm bearing is effected.
Figure 4 is another modification, also for rim locks. In this case the extended
part c of the follower b has a male screw thereon to screw into a tube or sleeve k,
which is adjusted to the thickness of the door to which it is applied. The
square spindle or cotter pin d is inserted in the square hole formed in the part c
into the knob e, and the knob g is secured by a screw collar as shewn, and which
is already known.
Figure 5 shews my Invention as applied to mortice locks; a is the lock in the
mortice in the door a¹; b is the follower, which has a screw thread in it for a
short distance at each end for the reception of the follower extension pieces c, k,
both of which have screw threads thereon and a square hole through them. The
piece c has a collar for the attachment of the knob, a section of this picce is shown
at Figure 6. The disc has apertures m, so that the lugs n on the handle or
knob g may pass through same, and the plate on which these lugs are formed being
turned partly round clip the aforesaid disc, as shewn. The knob e is screwed onto
the piece a distance according to the thickness of the door, and the piece c is also
adjustable in its bearing in the follower b the square bar d is passed through,
whereby the whole is locked as aforesaid.
Figures 7 and 8 refer to the second part of my Invention for fixing handles or
knobs to doors and drawers; Figure 7 is an end view, and Figure 8 a side
elevation of knob; o is a grooved projection on the knob; p is the plate or disc
which screws to the door for attaching the handle or knob thereto. This plate or
disc has a hole p made excentrically therein and corresponding with the external
diameter of the projection o, the disc p is slipped over the projection, and by
bringing it central with the knob it is held in the groove o. In order to screw this
plate or disc, which is immediately behind the rose 2, to the door I form in the said
rose a hole or openings of sufficient size for the heads of the screws to pass
through, this holo is brought opposite to one of the screw holes q in the plate or
disc and the screw screwed therein, the head passing through the hole s so that
it may be flush with the surface of the plate, the roser is then turned round so as
to bring the hole or opening s opposite to another of the screw holes q in the
plate p, and so on, until all the screws have been put in. This part of my said
Invention is also shewn in section at Figure 5 and indicated by the letters 7, 8.
By this means the plate p is screwed to the door without in any way removing
the rose T.
Having thus described and ascertained the nature and object of my said
Invention, I would remark in conclusion that I do not intend to confine myself to
the precise arrangements herein described, as the saine may be varied without
departing from the principle of my Invention, which 1 declare to consist in, and
I claim, first, elongating the followers of locks so that they may extend
through or nearly through the door or drawer to which they are to be attached,
whether such followers be made in one or more pieces, substantially as set forth.
Second. Method of constructing and fixing handles or knobs of doors and drawers,
substantially as described and shewn.
In witness whereof, I, the said William Harrison, have hereunto set my
hand and seal, this Eighteenth day of October, in the year of our Lord
One thousand eight hundred and eighty
WILLIAM HARRISON. (L.S.)
