Improvements in Bolts for Doors and the like.
I, SAM MENDEL, of 150, Marlborough Road, Hightown, Manchester, Watch-
maker, do hereby declare the nature of this invention to be as follows ;—
My invention has for its object improvements in bolts whereby bolts can be
mado to answer the double purpose of a spring catch and an ordinary lock.
1 form my bolt in the ordinary manner of spring bolts .e. with a spring at
the rear of the bolt with a casing, but in this outer casing 1 make a double slot
into which a pin, having, a suitable head or handle slides the top slot is much
shorter than the bottom one, in this top slot the pin on the bolt works ordinarily,
that is, when the door is required to simply fasten or "catch to," can be opened
by a push" but when it is desired to practically lock the door with the bolt,
the pin is pulled back and allowed to drop into the lower and longer slot which
allows the bolt to shoot forward a longer distance into the staple or recess into
which it takes. This staple or recess, is slightly tapered at the part which
meets the bolt to allow the bolt to easily slip in and out when not locked, or in
its normal position.

Improvements in Bolts for Doors and the like.
I, SAM MENDEL, of 150, Marlborough Road, Hightown, Manchester, Watch-
maker, 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 improvements in bolts whereby a bolt can be
made to answer the double purpose of a spring catch, and an ordinary lock.
I form my bolt in the ordinary manner of spring bolts, .e., with a spring at
the rear of the bolt within a casing, but in the outer casing I make a double
Blot in which a pin having a suitable head or handle slides. The top slot is
shorter than the bottom one, and in this top slot the pin in the slot works ordi-
narily, that is, when the door is required to simply fasten or 'catch to," and can
be opened by a "push," but when it is desired to practically lock the door the
pin is pulled back and allowed to drop into the lower and longer slot, which

takes. This staple or recess is slightly tapered at the part which meets the bolt
to allow the bolt to easily slip in and out when not locked or in its normal posi-
tion.
On the accompanying drawing Fig. 1 represents a front view partly broken
away of my improved bolt fastening in the position it occupies when used as a
catch. Fig. 2 represents a similar view of the bolt fastening in the position it
occupies when used as a lock. Fig. 3 represents a transverse section. Fig. 4
represents the application of the fastening to a mortice.
Referring to Figs. 1, 2 and 3, (A) is a tubular casing provided with lugs (B)
and holes for securing the fastening by screws (U) to the door, casement or othor
object to which it is applied. Within the said casing I mount a bolt (D) which
is an easy fit, and also within such casing and behind the bolt I place a spiral or
other spring (E).
In the wall of the casing I form two parallel slots (F), (F) of unequal length
and joined by a transverse slot (F). To the bolt (I)) I connect a stem or.
shank (G) which passes through the slot (F), or (¹), and upon the outside of
the casing carries a knob (H).
By the manipulation of the knob the bolt (D) may be caused to slide in the
casing and the stem (G) caused to play in the slot (F), or slot (F¹); so that by
reason of the stem connection with the bolt (D) lying in the slot (F) the bolt pro-
jects only slightly beyond the casing (A), as illustrated in Fig. 1, and in relation
to the fixed staple (1) acts as a catch, whilst lying in the slot (F) the end of the
bolt projects well into the staple (1), and thus acts as a lock, as shown in Fig. 2.
In Fig. 4 I shew how the fastening is adapted for use with a mortice, a lateral
opening being formed in the wood to allow of the movements of the stem (G),
and covered by a plate (J), having slots (F), (FI) and (Fª²) for regulating the
positions of the bolt.
To humor the fixing of the bolt (D), or plate (J) in relation to the staple, the
screw holes may be slightly elongated.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what
I claim is:-
1: In bolt fastenings for doors, casements and the like, a tubular casing,
a spring-pressed bolt within the casing, two parallel slots joined by a transverse
slot in the wall of said casing, a stem or stud on the bolt passing through, and
capable of playing in, the said slots, substantially as and for the purposes set
forth.
2:-In mortice fastenings, a spring-pressed bolt within the mortice, a lateral
projecting stem on the bolt, an opening in the door, and a plate over said opening
with parallel and transverse slots, substantially as and for the purposes set
forth.
Dated this in day of October Tovy.
