page_text: We, RICHARD FAIRWEATHER, Gentleman, GEORGE FENWICK BOYD, Solicitor, and
WILLIAM THOMAS ALLEN, Agent, all of 14 The Arcade Newcastle on Tyne in the
county of Northumberland do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to improvements connected with cartridge turning-down
machines the improvements consisting in the novel combination or arrangement of
certain well known mechanical parts with cartridge turning down machines so that
the latter shall be capable of accomplishing in a given time a relatively increased
amount of work as compared with former practice in the turning down of cartridges.
Hitherto these machines have been arranged and constructed so as to turn down one
cartridge at a time the operator in order to perform this operation having to exert
substantially the same amount of work in the turning over of the open paper end of
one cartridge as (as will be hereinafter shown) will suffice to turn down two three
or more cartridges arranged within our improved machine.
In order to fully describe our invention we will now refer to the accompanying
drawings in which Fig. 1 shows partly in plan and partly in sectional plan a machine
constructed to deal with the turning down of three cartridges at a time, Figs. 2 and 3
showing respectively a front end and side elevation of the same and throughout the
following description similar letters of reference in the specification and in the
drawings designate corresponding parts.
Referring to the Figs. A is a frame which may by preference be constructed of
brass iron or steel cast or wrought and fitted with a transverse front plate A¹ and
two other transverse plates or bridges A' A³. Between the plates A2 A3 we mount
three equally geared toothed wheels A* A* A* on spindles A' A' A' which pass
through and have their bearings in the bridges A' A². The bosses of the geared
wheels are preferably constructed of a length very slightly less than the length
between the bridges A' A' so as to form distance pieces between the same and thus
prevent any longitudinal sliding either of the bosses or of the spindles on which they
are mounted and to which they are keyed by transverse taper keys passing through
the bosses and the spindles. On the projecting ends (between the bridges A' A') of
the spindles A and keyed thereto by taper keys as hereinabove described with
reference to the bosses of the geared wheels we mount the cartridge turning down
cylinders A shown in plan section and end elevation in the drawings and arranged
in respect of their position and in relation to the fixed cartridge chambers A' in the
usual way and as shown in the drawings.

page_text: It will however be observed that as the direction of revolution of the turning
down cylinders A° changes in accordance with the changes of direction produced by
the geared wheels A* so do we find it advisable to arrange the stops A1 therein in
such a manner that the turning down surfaces thereon shall always face or point
towards the direction of revolution (caused or produced by the geared wheels afore-
said) of the turning down cylinder in which they are situated. A is a handle
connected preferably to the central spindle A. for giving revolutionary motion to the
geared wheels A spindles A and the turning down cylinders A and A10 is a curved
jaw attached to the frame A by screws A" and fitted at its lower end with a powerful
adjustment screw A" and clamping piece A¹³ for clamping the machine to a table
bench or chair in the usual way.
The operation of pressing the end of the cartridge to be turned down into the
circular grooves and against the stops A19 of the turning down cylinders A* is per-
formed substantially in the usual way but instead of the single lever as hitherto used
we arrange three T-headed levers A1 A1 A1 on a common axle A" mounted at its
extremities in bearings A¹ formed in lugs A projecting from the upper corners of
the transverse front plate A¹ the motions of the several levers being snychronous and
identical by means of the handle A 18 attached preferably to the central point of the
axle A as shown in the drawings. In the Figs. the T-headed levers are shown in
the position they occupy before the cartridges to be turned down, are inserted into the
respective chambers A but in Fig. 3 is shown in dotted lines the position which these
levers and their handle occupy when in the act of pushing the cartridges into the
grooves of the turning down apparatus.
The operation of our invention is thus as follows:-
Firstly having clamped the machine to any convenient point of support thrust three
cartridges A requiring turning down into the chambers A7 A7 A bring down the
pushing in levers A" into the position shown in dotted lines in Fig. 3 and while
turning handle A' with one hand keep pressing the cartridges into the grooves and
against the stops A19 of the turning cylinders A with the other hand by the aid of
handle A18. The usual number of revolutions will suffice to perform the operation
when the handle A18 can be thrown back into the position shown in full lines in the
drawings and the turned down cartridges removed to be replaced by another set of
three unturned cartridges and thus the operations may be repeated.
We do not confine our invention to the application of machines adapted to deal
with three cartridges at one time, as it is evident that the same principle can be
applied and in a variety of ways to machines adapted to deal with two three four
five six or even more cartridges at one time nor do we confine ourselves to the
specific combination or arrangement of parts as herein before set forth for it is evident
that similar results can be attained by a variety of modifications both in the number
and arrangement or disposition of the toothed wheels and therefore having now
particularly described and ascertained the nature of our said invention and in what
manner the same is to be performed we declare that what we claim is
(1) In cartridge turning down machines the combination of parts consisting of
the provision in one machine of duplex or multiple cartridges chambers (A').arranged
so that while each such cartridge chamber has a separate turning down cylinder (A)
and pushing in lever (A") the operation of turning: down the cartridges in the
several chambers is synchronous and identical substantially as hereinbefore set forth.
