I, FREDERICK TAYLOR, of 14a St. Petersgate, Stockport, in the County of Cheshire,
Photographer, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in doors bolts and has for its object to
produce a door bolt, which when actuated will simultaneously fasten or release the
leaves of a folding door, or retain one leaf fastened while the other is permitted to
swing.
The improvements consist in suitably forming an ordinary straight door bolt, near
its free end, with a radial branch bolt, which latter when the main bolt is turned by
means of a small handle formed thereon, rotates concentrically with the main bolt, and
can be turned backwards or forwards so as to fasten either only one or both leaves
of the folding door simultaneously by pushing the bolts into holes formed in the door
post or plate attached thereto.
This double door bolt is suitably secured to the leaf of the door which is generally
kept fast, and is provided on its end with a loose catch arranged to engage a
projection or equivalent by means of which the bolt can be retained in a raised
position.

Photographer, 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 relates to improvements in door bolts and has principally for its
object to produce a door bolt, which when actuated, will simultaneously fasten or
release both leaves of a folding door, or retain one leaf fastened while the other is
permitted to swing.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a front view, Fig. 2 a plan of the whole and Fig. 3 a side view of the
lower part of my improved door-bolt. Fig. 4 shows the same applied to a folding
door.
Referring to the figures generally, the improvements consist in suitably forming or
providing an ordinary straight door bolt A, near its free end, with a radial branch
bolt a, which latter when the main bolt A is turned by means of a small handle a¹
formed thereon, rotates concentrically with the main bolt A, and can be turned back-
wards or forwards, so as to fasten either only one or both leaves of the folding door
simultaneously, by pushing the bolts A and a into respective holes formed in the door
post or plate b, attached thereto.
This door bolt A, a, is as usual arranged to be slid up or down and partially rotated
on a plate B, suitably secured to the leaf of the door which is generally kept fast,
and is provided on its end with a loose catch c arranged to engage a projection d,
by means of which the bolt A, a, can be retained in a raised position.
The dotted lines in Figs. 1 and 2, represent the door holt A withdrawn, so as
to permit the opening of both leaves, and the full lines, when both leaves are bolted.
To retain the leaf fastened, to which the bolt A is secured, the radial branch a is
turned against the same, so as to give the door to be opened, free play.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. In bolts for folding doors, forming or providing the bolt A with a radial
branch bolt a, for the purpose of fastening both leaves simultaneously, substantially
as set forth.
2nd. In door bolts, providing the bolt A with a loose catch c capable of swivelling
thereon, in combination with a projection d, for the purpose of retaining the bolt A in
position, when raised, substantially as set forth.

Attaching Door Knobs and Handles to their Spindles.
1, FREDERICK TAYLOR, of 14ª St. Petersgate Stockport in the County of Cheshire,
Photographer, do hereby declare the nature of this invention to be as follows:-
My invention relates in the first place to improvements in latches or locks for doors
and the like, and in attaching door knobs and handles to their spindles, and has for
its object to simplify the action of such by bringing the latch bolt in connection with
the door spindle or knob in such a manner that on pushing and pulling the latter, the
latch bolt will be drawn back, while by the action of a spring the same is forced
forwards again on releasing the knob.
The improvements consist in forming the latch bolt in or about the middle, with a
horizontal incline which is actuated upon by means of another corresponding incline
formed on the spindle of the latch, which is mounted in holes formed in the casing of
the same.
In order to minimize friction between these two inclines, and also between the
bolt and staple box I provide one of the said inclines and the staple box where the
bolt touches, with an anti-friction pulley.
The second part of my invention relates further to improvements in an invention
for which Letters Patent were granted to Alfred Overfield dated April 29th 1884,
and numbered 6960, and has for its object to render the action of the same more easy,
and facilitate an easy fixing of the latches or locks to the door.
To this end I employ on the side of the latch bolt upon which the push-pin
actuates, an anti-friction pulley, thus facilitating an easier sliding of the latch bolt.
The hole, through which the push-pin passes, on the side of the latch casing which
comes to lie next to the door, I form with a small flange, which when pressing the
latch in its proper position against the door, will embed itself into the same and thus
indicate the position of the hole to be bored through the door for the reception of the
push-pin, thus facilitating the fixing of the latch lock.
In order to facilitate the use of only one size of push pins, for the various thick-
nesses of doors I make the same so as to be lengthened or shortened at leisure, by

page_text: forming it in two parts, one screwing into the other and locking the same to a certain
length by means of a lock nut.
The invention relates in the last place to improvements in the attachment of door
knobs or handles to their spindles & has for its object to facilitate a quick and
durable attachment of the same.
The improvement consists in forming the ends of the door spindles with a thread
onto which I screw the door knob or handle and lock the same in position by means
of a lock nut placed behind and between the door knob or handle and the door itself,
which retains the knob or handle always in any desired position and also facilitates
the use of one length of spindles for different thicknesses of doors.

Attaching Door Knobs and Handles to their Spindles.
I, FREDERICK TAYLOR of 14ª St. Petersgate, Stockport in the County of Cheshire,.
Photographer, 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 :-
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a front elevation, Fig. 2 a side elevation, Figs. 3 and 4 sectional plans
of my improvements.
My invention relates in the first place to improvements in latches or locks, and has
for its object to simplify the action of such by bringing the latch bolt in connection
with the door spindle or knob in such a manner that on pushing and pulling the latter,
the latch bolt will be drawn back, while by the action of a spring the same is forced
forwards again on releasing the knob.
In carrying out this part of my invention and referring to Figs. 1. 2. & 3 the
improvements consist in forming the latch bolt A, in or about the middle, with a
horizontal incline a, which is actuated upon by means of another corresponding
incline 6 formed on the spindle or pin B of the latch, which is mounted in holes
formed in the casing C of the same.
In order to minimize friction between these two inclines a & b and also between the
bolt A and staple box A' I provide one of the said inclines, preferably b, and the
staple box, where the bolt A touches, with anti-friction pullies 6' & c', respectively.
The bolt A being under the action of a spring D pressing against the end of the
same is caused to enter the staple box A', when the door E is closed, and on a push
or pull being exerted on the spindle or pin B the bolt A will get withdrawn by reason
of the inclines a & b.
The second part of my invention relates further to improvements in an invention
for which Letters Patent were granted to Alfred Overfield, dated April 29th 1884,
and numbered 6960, and has for its object to render the action of the same more easy,
and facilitate an easy fixing of the latches or locks to the door.
To this end and referring to Fig. 4, I employ on the side of the latch bolt A,
upon which the push-pin B acts, an anti-friction pulley 6', thus facilitating an easier
sliding of the latch bolt.
The hole through which the push-pin B passes, on the side of the latch casing C,
which comes to lie next to the door E, I form with a small flange c, which when
pressing the latch in its proper position against the door E will embed itself into the
same, and thus indicate the position of the hole to be bored through the door E, for
the reception of the push-pin B, thus facilitating the fixing of the latch lock.
In order to facilitate the use of only one size of push-pins B, for the various

page_text: thicknesses of doors E, I make the same so as to be lengthened or shortened at
leisure, by, forming it in two parts 6' & 6³, one screwing into the other, and locking
the same to a certain length by means of lock-nut F.
The invention relates in the last place to improvements in the attachment of door
knobs or handles to their spindles, and has for its object to facilitate a quick and
durable attachment of the same.
In carrying out this part of my invention, & referring most particularly to
Figs. 2 & 3, the improvement consists in forming the ends of the door spindle or
pin B with a thread, onto which I screw the door knob G or handle, and lock the
same in position by means of a lock nut F placed behind, and between the door knob G
or handle, and the lock or door E itself, which retains the knob G or handle always
in any desired position and also facilitates the use of one length of spindle B for
different thicknesses of doors E.
This lock-nut F I form with a small boss f, and thread thereon, to screw into a
corresponding recess g, formed in the knob G or handle of the door, so as to obtain
a double grip, and very secure locking of the knob G or handle.
The said lock nut may be circumferentially milled or formed with one or more holes
to facilitate the setting of the same.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is :-
In latches or locks, the use of a spindle or pin B projecting through the lock or
latch and door, on each side respectively, formed in or about the middle with an
incline 6, in combination with an incline a, formed on the bolt A under the control
of a spring, which inclines a &b cause the bolt A to be withdrawn on a pull or push
being exerted onto the spindle or pin B, substantially as set forth.
2nd. Providing the inclines a &b and staple box A', with anti-friction pulleys,
substantially as set forth.
3rd. Forming the push pin B, in the class of latches or locks as illustrated in
Fig. 4, in two parts so as to be capable of being shortened or lengthened as required,
and suitably locking the same, substantially as set forth.
4th. In the class of locks or latches named in the preceding claim, forming the
push pin hole in the casing of the latch or lock, with a flange, for the purpose and
substantially as set forth.
5th. Fixing door knobs or handles to their spindles or pins by locking the knob
or handle in the required position by means of a nut F, Fig. 3 bearing against the
inner side of the same, substantially as set forth.
