Specification of Letters Patent.
Application med Augut s, 1917. seal mi. 185,107.
To all whom 'it may concern:
Be it known that I, 'GEORGE Column., a citizen of the United States of America residing at Kearney, in the county of lay and State of Missouri, have invented new and useful Improvements in Periscope AtfV tachments for Rifles, of which the following is a specification.
or user concealed 1n a trench and without causing the soldier to expose himself to the fire of the enemy when firing the rifie.
It is an equally important object of this invention to provide a deviceof the above mentioned character wherein the construction is novel and permits of a quick application and removal of the attachment to a frame of a rifle and is capable of being folded into a compact -form when not in use so that it can be conveniently carried by a soldier, etc.
More particularly this invention embraces the provision of a periscope attachment for ries wherein an auxiliary or secondary stock and trigger are employed in conjunction with the periscope proper while suitable means connects the secondary trigger with the main trigger so that the operator or soldier may aim the barrel of the riie without exposing himself to the enemy and Iire the rifie when holding the secondary stock by merely pulling the secondary trigger.
As a further improvement the present invention includes the provision of a device of the above character wherein improved means is employed for assuring of an effective attachment of the device to a riiie so that the periscope proper will be positioned to reiect the sight of the gun barrel to the operator or soldier in the trench enabling the soldier to accurately aim and fire the riiie.
Among the other aims and objects of this invention may be recited the provision of a device of the character described with a view to compactness, and in which the numperl of parts are few, the construction simple,
`the oost of production low and the eliiciency high.
Other improvements and novel details in the construction and arrangement of the various parts of the apparatus will be brought out more in detailinrthe accompanying description which for a clear understanding of the invention should be considered in connection with'the drawings forming a part hereof, and wherein is disclosed for the purpose of illustration a convenient and satisfactory embodiment of the invention. It is to be noted in this connection that minor changes inthe construction and arra rement of the parts may be made without eparting from the principle of operation of the various parts.
The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the device attached to a riiie, the dotted lines showing the position assumed by the attaching arms and the secondary stock with respect to the periscope proper, when the device is in a folded position;
Fig. 2 is a front elevation of the invention;
Fig. 3 is an enlarged vertical sectional detail of the periscope proper;
Fig. 4 is a detail `of the trigger clamp;
Fig. 5 is a fragmentary elevational detai of the secondary 'stock and trigger.
Similar characters of reference are employed in all the above described views, to indicate corresponding parts.
Referring now, more particularly to the accompanying drawings, there is provided a rifle indicated in its entirety by the numeral l, being preferably of a conventional type and including generally a barrel 2 in the upper surface of which is mounted a sight 3. A stock 4 serves to support the barrel while a trigger 5 is mounted inthe riie to assure of the firing thereof. It is to be appreciated that this invention is not to be limited to the particular form or construction of the rifle, the latter being merely illustrated that a comprehensive understanding of the invention may be obtained.
Removably mounted on the stock 4 is the improved periscope attachment which in the present instance may be said to consist of a periscope proper, indicated in its entirety by the numeral 6 and consisting of a tube 7 on the upper and lower ends of which are respectively feras@ .Sight bares s and,

9. Pieces of plainv glass'lO are mounted in the outer ends of the sight boxes for protecting the diagonally arranged mirrors 11 removably insertible through openings 12 in 'I the tube in position on the stock 4, a socket 14 is carried by one face of the tube in proximity to the upper end thereof, the outer end being flared as at, 15 to facilitate the application of the free end of the stock 4, while suitable fasteningdevices such as set screws 16 are employed for removably maintaining the stock within the socket. The socket is formed at a suitable point beneath the upper sight box 8 so as to maintain the latter in substantial alinement with the sight 3 to assure of the reflecting of the sight through the tube to the lower sight box for a purpose ,that will hereinafter become apparent.
Bracing arms 17 are arranged on opposite sidesI of the tube 7 and have their upper ends A connected to the tube and to the socket through the instrumentality of suitable fastening devices 18 to increase the rigidity of the vtube in the socket while suitable fastening devices 19 are also employed for fasten- -ing vthe lower portions of the arms to the ears 13. rI "he extreme lower portions of the arms terminate below. the lower sight box 9 to facilitate the supporting of the periscope. Spaced' attaching and bracing arms 20 are now employed and are arranged adjacent the lower ends upon the outer surfaces of the lower portions of the arms 17 being pivotally connected thereto through the instrumentality of a suitable pintle 21. The attaching` armsfare bent upwardly as indicated by the numeral 22 and have their upper ends arranged upon opposite sides of the forward ,portion of the stock 4 of the riie. Bolts 23 and 24 are extended through thesections at points adjacent the upper and lower edges of the stock 4 while suitable adjusting elements, such as wing nuts 25, are threaded upon the projecting extremities of the bolts and serve as a means for clamping the upper portions of the arms 20 upon opposite sides of the stock 4.
A secondary or auxiliary stock 26 is now employed while bars 27 are connected on opposite sides and longitudinally of the stock by means of suitable fastenin devices 2,8 thejinner ends of the bars 27 bemg pivotally connected -through the instrumentality of suitable fastening devices 29 to the extreme lower ends of the arms 20 so as to dispose the stock 26 below and in the rear of the lower slght box 9. In this connection it will be observed that the downward'movement of the stock is limited when the inner end thereof abuts the adjacent side edges of the bracing rod 17. A. set screw 29 is mounted through the angularly bent portion of one of the arms 20 Iand is designed to be frictionally4 engaged against 'the end of the secondary stock 26 so as to removably hold the latter in the position indicated in full lines in' Fig. 1. A secondary trigger 30 is pivotally mounted as at 31 on the secondary rifle stock while a trigger guard 32 depends from the under edge of the stock adjacent the inner end as indicated, Y
As intimated, improved means have been provided for operably connecting the triggers 5 and 30 so that upon actuation of the secondary trigger the main trigger will be simultaneously actuated-to fire the rifle, subsequent, of course, to the correct sighting of the riiie. In reducing this feature of the invention toA practice a cable/33 formed of wire has one end connectedl to an eye 34 formed on the trigger 30 and is trained about guide pulley wheels 35 and 36 journaled transversely of the arms 2O respectively at points adjacent the bend v22 and adjacent the upper .ends of the arms while the opposite end of the cable is connected'to an extension 37 formed on the clamp 38 which in turn is removably connected to the trigger 5 through the instrumentality'of a fastening screw 39. Y
The mode of operation of the present in-u vention may be reviewed as follows Assuming that the parts .have been assembled in the manner described andas indicated in the drawings, the operator of the device by merely holding the'stock 26 against his shoulder in the manner of the usual gun stock by looking through" the lowerv sight `box will be able to see the reflection of the sight 3 and roperly adjust the rifle barrel 2. Subsequent y, of course, it is only. necessary to pull the trigger 30.and by reason o the flexible cable 33 between the trigger A3 0 and' the trigger 5 'of the vrifle the latter will be ired. Since the barrelof the rifle is adapted to rest on the topof the' trench, not shown,l
the operator or soldier may aim and re the rie in the bottomy of the trench without exposing himself tothe fire :of the enemy.
Whens it is not desired to use the device.
it is only necessary to loosen the set screws 16, the wing nuts 24 and the screw 39 in the clam) 38 to consequently respectively allow for t e removal of the stock 4 from the socket and the clamp 38 from engagement with the trigger 4. After detaching the device it is only necessary to swing the attaching arms 14, the arms from engagement with the stock the folding of the parts into compact form so that it can be readily and convenientlyy be interpreted as illustrative and not in a limited sense. It is also to be understood 'that the language usedin the following claims is intended to cover all the generic and specific features of the invention herein described and all statements' of the scope of the invention which, as a matter of language, might be said to fall therebetween.
Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is l. An attachment for rifles including a periscope, means carried by the periscope for receiving the rifle stock, bracing rods connected to the periscope and to the receiving means and terminating beneath the lower edge of the periscope, attaching arms pivotally connected to the bracing rods and removably clamped upon the rifle stock, a secondary frifle stock removably connected to the attaching arms and positioned beneath the periscope, a secondary trigger pivotally mounted on the secondary stock, and flexible means operably connecting the secondary trigger with the trigger of the rifle.
