Improvements in Automatic Locks.
CARLO ANGELO DAINESI of Milan in the Kingdom of Italy Mechanical
Engineer, at present residing at 35 and 37 Warner Street Clerkenwell E.C. do
hereby declare the nature of this invention to be as follows:-
Figure 1. Front plate having a hole A which may take any form suitable to-
receive and hold a bolt lock, which has at its extremity a holdfast tooth so made
that by another hold fast tooth entering from the exterior slip or slide, it cannot.
liberate itself without the raising or pulling of the slip internally of the apparatus.
This system of enclosure may also be applied to hold at the doors or other places,.
milk cans, or other recipients and to impede the opening of the lids or covers, I fix
a catch on the external part of the apparatus.
Figure 2. Automatic inclosure or lock, the action of the oldfast is created by a.
spring or springs, by the gravity of its own weight or even with balance weight..
The raising of the oldfast tooth is created through B upon pulling which it raises
the holdfast tooth releasing and pushing outwards the bolt or lock.
Figure 3. Automatic inclosure or lock, the piece C. is lengthened so as to project.
or to overhang sufficiently and obtain by pressure or pulling the lifting of the
holdfast tooth releasing the bolt or lock.
Figure 4. Automatic inclosure or lock, the slip or slide D may function or
operate through the gravity of its own weight or by a spring or springs and the
raising or lifting of the holdfast of the slip or slide, by a branch or arm ending
with a projection or overhang to be lifted or pressed, or even by a puller in a.
downward position to the axis of the slip piece.

Improvements in Automatic Locks.
I CARLO ANGELO DAINESI of Milan in the Kingdom of Italy, Artisan, at
present residing at No. 35 and 37, Warner Street, Clerkenwell in the County of
Middlesex, 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 :-
One of the object of this my invention is: for to have a simple and effective
means of fixing or locking at the door-house or other places milk-cans or any other
suitable articles, by fixing to them by any means and in any suitable part of the
same one or more "bolt" (l.) said bolt or bolts when are introduced in hole G. of
the frontal lock-plate A. are locked automatily, or open in the mode shown and.
described in Fig. 2. and Fig. 4.
Another object is: when have any kind of articles with cover, locked at any
suitable place, and said cover is wanted keep shutted till the body of the article is
unlocked, I obtain the locking of said cover or covers, by fixing or formoming
with the same lock-plate a lug. H. Fig. 1. and H. Fig. 2.
:
Another object is to obtain with locks of all kind and for all suitable purposes,
the expulsion automatily of the bolt (locked in the lock or locks from outside),

page_text: by doing said bolt-lock of locks in the manner shown and described in Fig. 4, and
for certain particular purposes, also in Fig. 2.
Another object is to obtain the expulsion automatily of the bolt in every
kind of suitable locks, when the bolt-lock is open, and this by means of spring or
springs, applied in a manner, such as not to impeded the function of running of
said bolt-lock when in use, and also shown and described in Fig. 3. of drawings.
Fig. 1. The front plate having a suitable cavity G., which will receive and hold
any suitable form, above cavity I fix lug H., which will prevent the opening of
covers of milk-cans or other receivers till they are taken off or unlocked; in Fig. 2
I can make lug H., by bending end of front plate A., or by fixing lug on to it, or
on to door if wanted.
Fig. 2. In locks the use of an internal bolt-lock, which is either a combination
lock, or can be made not so, whichever should be wanted when made by pulling
rod of wire B., having attachment in U., it raises cam D., having circular motion
on pivot P., and pushes bolt (., out, therefore releasing lock; cam D., is held in
the shutted position, by the gravity of his own weight, or by balance weight or
.even by spring or springs, applied in any suitable point.
Fig. 3. The bolt of locks of all kind, is pushed out by a spring or springs C.,
Fig. 4. The bolt is pushed out-when lock is being opened, by a taper surface E.,
..which releases bolt from the lug F.
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 I
claim is:
Firstly. It prevent the opening stealing or otherwise tampering with whatever
the locks are holding milk-cans or other receiver, and to do so "the use of lugs" H.,
Fig. 1. & 2.
Secondly. In locks Fig. 2. it is a special form of an internally opening lock, a
circular motion cam D., on pivot P., which acts doubly, by raising cam D., it
pushes out bolt 1., and therefore fully releasing lock and anything it should be
holding.
Thirdly. In every kind of locks the bolt ., of the locks obtains its expulsion or
release by a propelling power of a spring C., or springs.
Fourthly. The locks by having an inclinated surface E., at the end of bolt l.,
make a slide cam action to force bolt l., out.
