An Improved Cartridge Turnover Machine for Crimping or Turning
Over the Edges of Cartridges after they have been Loaded.
HENRY MONK 75 Foregate Street Chester in the County of Chester Gunsmith 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:-
Cartridge turnover machines as heretofore constructed are not automatic in their
action, they require the cartridges to be placed and held in position while they are
being turned over by hand.
The disadvantage of such machines is that they have to be worked by skilled
hands, are slow, and dont do their work with perfect regularity.
The object of my invention is to provide a machine which when it is filled will
bring the cartridges into position and turn the ends over automatically putting a
uniform pressure onto each without the aid of any skilled attention whatever. To
enable my invention to be clearly understood I will describe the same with reference
to the accompanying drawing which is a part sectional front elevation of a cartridge
machine constructed according to my invention.
a is the driving wheel.
b is a toothed spindle with an ordinary turnover disc c attached.
D is a large toothed wheel with a cam E attached to one side and an eccentric
groove fin the other side.
G is a cranked arm which as the toothed wheel d is turned by the toothed spindle b
the long slope of the cam E pressing against the small roller H draws the cranked
arm G forward, as it is drawn forward the flange end of the cartridge I gets jammed
in the tapered disc J which keeps it from turning round as the paper end of the
cartridge I is being turned over by being pressed against the revolving disc c. When
a sufficient number of turns have been given to the paper end of the cartridge I the
largo toothed wheel d will have made one turn, when the small roller H will run
down the short slope of the cam E¹ thus causing the cranked arm G to go back to its
place.
K is a piece of steel wire which as the cranked arm G goes back to its place the
end of the wire catches on the pin L and forces the flange end of the cartridge I out
of the tapered disc J and leaves it in position to be ejected by the next cartridge I'
coming into position. The dotted lines show the wire K in position when the
cartridge is pressed up.
M is a box into which the cartridges to be turned over are placed it has a sliding
bottom with a space into which a cartridge falls.
N is a pivoted arm the end of which working in the eccentric groove fis given a
backward and forward motion. As it comes forward it brings with it the sliding
bottom of the box M with the cartridge I' in the space which pushes away the
cartridge I that has just been turned over and falls into its place the sliding bottom O
is then taken back by the arm N and another cartridge falls into the space and is
brought forward in its turn.
P is a spiral spring which gives when sufficient pressure has been put on the
cartridge. The pressure can be regulated by the thumbscrew q.

page_text: 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. An automatic cartridge turnover machine which will turnover any number of
cartridges by simply placing them in the box without the aid of any skilled attention
whatever.
2. The manufacture and use of the machine hereinbefore described and illustrated
in the accompanying drawing.
