The rifle is cocked and loaded ready for firing by pressure on the trigger« Note the shape and position of the powerful ejector whose rear end is cammed down as the bolt is pulled to the rear, thereby lifting the front point of the ejector sharply to knock the empty case out the top of the rifle.
the drawings which form part and parcel of it. As regards the patents awarded in other countries, not requiring an identification of the inventor, we quote here abstracts from Austrian Patents 17864 XIX0 and XIX26 which are in German, and will therefore be clear to the reader. These patents, representing the fruit of the work of the Mauser brothers (in particular of the practical labor of Paul Mauser), show beyond the shadow of a doubt that the weapon covered by these patents, and which became known to the general public as the "Mauser-Norris rifle," or simply as the "Norris rifle," actually embodies the principal technical features of the Mauser lock, wherefore it is of utmost importance not only from the historical point of view, but also practically in the development of Mauser rifles, and of portable firearms in general.
2nd Model: Some time after the completion of the weapon known as "Mauser-Norris rifle," another model rifle was perfected; as regards its lock arrangement, this later model is identical with the single-loader described above, but it embodies certain detail improvements, and it represents in fact the intermediate stage between the "Mauser-Norris rifle" and the German M. 71 rifle. As far as it can still be ascertained, this rifle shows the following changes:
The mainspring (attached to the handle in the previous model) is dispensed with, and replaced by the strong spiral spring, lodged in the chamber and surrounding the striker.
A guide-rib is provided for the chamber; this guide-rib is joined to the foot of the handle, and it forms the breech base. Its forward part, protruding over the end of the chamber, has a transverse groove or notch, and when the breech mechanism is opened, this groove or notch extends with a shoulder over a nose of the bolt-head (which is inserted into the chamber end without any coupling, i.e. without any stop to prevent its longitudinal displacement, although it does not share the turning movement of the chamber), carrying the bolt-head along when the chamber is pulled back.
The snap is pushed on the rear end of the striker, as a separate part, and is kept in its place by the separate striker nut, screwed onto the striker behind the snap.
The self-cocking is effected as follows: A projection is provided on the forward end of the snap, and a chamfering or recess on the rear end of the chamber, so that they engage each other when the locking is effected. When the chamber is turned up, the projection and the recess slide along each other, whereby the snap is forced back, and the spiral spring, surrounding the striker and serving as mainspring, is cocked.
Furthermore, this rifle was the first to have a safety device of the cocked lock, in connection with the snap; this safety device consists of an adjustable retaining piece which takes up a position between the chamber and the snap when the handle is pointing upward, thus preventing the snap from flying forward.
Patents: The financial backer who had applied for a patent for the first "Mauser-Norris design" for his own account and in his own name, neglected to have the above improvements patented. The Mauser brothers were not in the position to apply for the necessary patents, for at that time whatever modest financial resources they possessed were needed primarily for the expenses of the production of the various test and trial rifles. Moreover, it was anyway impossible to acquire a sufficiently ample patent protection in the German States, for it is a well known historical fact that in the absence of a universal German Reich patent law, there was no patent protection available in those days for the entire territory of the Reich."
