CRIIVH. PROTECTOR.

Application filed January 15, 1924. Serial No. 686,358.

T 0 all whom it may concern:

Be it known that I, AUsUs'r EHRHARDT, a citizen of the United States, residing at San Benito, in the county of Cameron and State of Texas, have invented new and useful Improvements in Crimp Protectors, of which the following is a specification.

This invention relates to magazine guns and has particular reference to the spring pressed plunger or follower used in the magazine for the purpose of forcing the shells through the magazine to a position for use.

It has been observed that the crimp on the shell arranged next to the spring pressed plunger above referred to, becomes battered and swollen by the reaction of the spring each and every time a shell is extracted therefrom, and that fact is so regardless of the make of the magazine.

I have therefore contemplated the provision of means to prevent injury to the crimp on the shell above mentioned, so that the shells can be extracted in the usual manner from the magazine, without the spring pressed plunger having any detrimental effect upon the particular shell mentioned.

More specifically stated, I have proposed forming a boss or extension on one end of the spring pressed plunger, and giving this boss or extension a size to permit it to enter the adjacent end of the shell and bear againstthe wadding thereof, and in this manner either slightly space the plunger from said shell, or to relieve the latter of the force and detrimental effect of the spring pressed plunger as above described.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this ap plication, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a fragmentary view partly in section of a magazine gun.

Figure 2 is an enlarged view partl i section showing the boss or extension formed on one end of the plunger positioned within the adjacent end of the shell bearing against the wadding thereof.

Figure 3 is a detail view of the spring pressed plunger.

The invention is primarily intended to protect the crimp on all paper shot shells used in any magazine gun regardless of make, or gauge, and upon reference to the drawing, 10 indicates such shell. These shells are of course arranged in the magazine 11 of the gun and are adapted to be singly extracted therefrom for use in the usual well known manner. These shells are forced through the magazine for this purpose by means of a spring pressed plunger 12, the latter being usually of hollow forn1ation and receiving a spring 13 arranged in the manner illustrated in Figure 1.

In accordance with the present invention this spring pressed plunger has that end lying next to the shells 10, formed with a boss or extension l i, and the latter is of a size to fit 'within the end of the shell 10 lying next to the plunger as shown in Figures l and 2. Consequently, when the gun is operated to extract the shell from the magazine, the spring pressed plunger is not permitted to forcibly come into contact with the crimp 15 on said shell, which usually becomes battered and swollen by the reaction of the spring as above stated. On the contrary, the boss or extension contacts the wedding of the shell and the arrangement of the parts is such, that the spring pressed plunger can be either. held slightly spaced from said crimp or the latter can be relieved of the force and detrimental effect incident to the operation of the plunger. The boss or extension is preferably of a size, however, to prevent the spring pressed plunger from bearing or resting against the crimp of the shell as illustrated.

\Vhile it is believed that from the foregoing description, the nature and advantag -.s of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired. as fall within the scope of what is claimed.

Having thus described the invention, I claim:

In a magazine gun, aspring pressed plunger arranged for operation Within the 5 magazine to force the shells therefrom, a

disk-like element secured to one end of the plunger and having a diameter to permit said disk to enter the opening in the adja cent end of the shell and Contact the Wadding of said shell, said disk serving to prevent the plunger from contacting the crimp end of the shell for the purpose specified.

In testimony whereof I affix my signature.

AUGUST EHRHARDT.
