I, JOSEF SCHULHOF, Engineer of 4 Nibelungengasse, Vienna in the Empire of
Austria, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements upon the subject matter of the
Specification of Letters Patent granted to me bearing date the 12th day of July 1886,
No. 9066.
These improvements consist in replacing the chain described in the said Specifi-
cation as the means for tightening the magazine feed spring (as the door of the
magazine is being opened) by a cogged segment pivoted upon the rear end of the
magazine. The cogs of this segment gear into corresponding cogs on the end of
the central feed drum in such manner that when the magazine door is being opened
a projection or shoulder of the said magazine door will engage with a pin attached to
said cog segment whereby the said segment is turned on its pivot and gives one
revolution to the central feed drum. This effects the tightening of the before
mentioned feed spring. When the door is entirely open the last tooth of the said
cogged segment acts as a stop to the feed drum until the door is being closed when
the feed drum and with it the feed spring are again released.
The improvements consist further in making the feeder of one solid piece rigidly
attached to the feed drum instead of it being pivoted thereupon and provided with a
spring as described in the Specification under the before mentioned Letters Patent.

page_text: I, JOSEF SCHULHOF, of No. 4 Nibelungen Strasse, Vienna, Austria, Gentleman,
do hereby declare the nature of my said invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement:-
This invention is an improvement of the magazine, Letters Patent for which were
granted to me on the 12th day of July 1886, No. 9066.
The improvements consist in the substituting for the chain employed in said Patent
for operating the magazine drum, of a more simple and reliable mechanism and in
substituting for the oscillating feeder described in above Patent, a stationary or rigid
cartridge feeder.
These improvements are represented on the accompanying drawings in which,
Figure 1 is a rear view of the magazine with door closed, detached from the rifle.
Figure 2 shows the same with door opened.
Figure 3 is a vertical cross section of a magazine filled with cartridges.
Figure 4 is a front view of the magazine.
Figure 5 is a longitudinal section of the same.
The one end, near the rear end of the magazine arbor h, is provided with teeth h¹
into which engages a correspondingly toothed piece or segment 2. This piece /²
turns upon a pivot upon the rear end of the magazine, which as here shown, may be
formed by one of the pivots g¹ upon which swings door g¹. Door gt is at its lower
part provided with a lug or an extension g', which when the door is pulled open
strikes against a pin ³ attached to cog segment h², whereby the latter is turned upon
its axis as the door is being opened.
Piece gearing into the teeth upon arbor h, the latter naturally receives a
revolution by the turning of the former h² upon g¹. By the revolution of arbor h,
spring which is attached to the other end of arbor h and of the magazino, is
tightened. When the door has been entirely opened, segment h² arrives in tho
position shown in Fig. 2, whereby the last tooth (to the left) of piece /² is placed in
such manner underneath one of the teeth of the arbor, that it acts as a stop to
the latter and prevents its being turned back by the tightened spring 2. For
preventing piece ² from being turned too far to the right a stop pin h¹ may be
attached to the magazine.
When the door is now closed, piece 2 being free upon pivot g¹ remains in its
position (Fig. 2) until the door is almost shut, when the edge of the latter or a pro-
jection attached thereto strikes the last tooth to the right of piece h², whereby the
latter is again thrown into proper gear with the teeth upon the arbor h. Now
spring will turn arbor / back into its original position, which revolution causes the
cartridges placed in the magazine around arbor h to be fed to the breech of the riflo
by feeder q attached to arbor h.

page_text: When the magazine is emptied, piece h² has arrived again in the position shown
in Fig. 1 and the operation can be repeated. The improvement in the cartridge
feeder is shown in Fig. 5 and simply consists in employing for this purpose a rigid
wing or web attached to arbor q instead of the oscillating feeder described in Patent
No. 9066.
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. In magazines for repeating firearms the employment of a toothed piece or cog
segment 2 turning upon pivot g' and gearing into teeth h¹ placed upon arbor h of
the magazine; piece 2 provided with a pin or projection against which strikes
door g by means of its projection or extension g6 when being opened, substantially as
described in the foregoing specification and shown in the accompanying drawings.
2. In magazines as described in claim 1, a rigid feeder q attached upon arbor h
substantially as described in the foregoing specification and shown in the accompanying
drawings.
