MAGAZINE ATTACHMENT FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 764,243, dated July 5, 1904.

Application filed March 7, 1904. Serial No. 197,029. (No model.)

To all w/zmn zit nuty concern:

Be it known that I, THOMAS C. J OHNSON, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Wrench Attachments for Tubular Magazines for Guns; and I do hereby declare the following, when taken in connection with the accompanying drawings and the figures of reference marked thereon,

to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a broken view, partly in side elevation and partly in vertical longitudinal section, of a gun the tubular magazine of which is provided with one form which my improved wrench attachment may assume; Fig. 2, a detached broken view of the front end of the magazine, which is shown in vertical section with the wrench attachment in elevation and in its operative position; Fig. 3, a View in front elevation of the magazine and wrench attachment, which latter is shown in its operative position; Fig. 4, a detached View, in side elevation, of the wrench attachment; Fig. 5, a detached reverse plan view thereof; Fig. 6, a detached view of the wrench attachment, partly in central longitudinal section and partly in elevation; Fig. 7, a detached view of the wrench attachment in front elevation.

My invention relates to an improvement in attachments for use in screwing tubular magazines into and unscrewing them from gunframes, the object being to permanently provide tubular magazine-guns with simple and convenient means for removing and replacing their magazine as required.

With these ends in view my invention consists in the combination, with the front end of a tubular magazine, of a wrench attachment mounted in the said end of the magazine for endwise movement therein in line therewith, whereby it may be normally retired thereinto and when required for use pulled out therefrom and swung on its inner end as on a pivot and brought into position at a right angle to the magazine and then used as a wrench for turning the magazine one way or the other.

My invention further consists in a wrench attachment for tubular magazines having certain details of construction, as will be hereinafter described, and pointed out in the claims. In carrying out my invention as herein shown-I employ a wrench attachment in the form. as may be said, of a spanner-wrench. This consists of a straight shank 2, furnished at its outer end with a hollow operating-button 3 and at its inner end withatrunnion-like arm 4:, arranged at a right angle to it, round in cross-section, and formed with a transverse perforation 5 for the reception of a retaining pin 6. At its outer end the shank is formed with a locking-shoulder 7, which is placed directly opposite a retaining-spring 8, located in part in a longitudinal slot 9, formed in the shank, the outer end of the spring extending into a hole 10, formed in the button 3, and its inner end being bent at a right angle and inserted into a hole 11, leading out of the bottom of the recess 9. A locking-notch 7 isformed between the shoulder 7 and the innenna; face of the button 3, the shoulder and button..

holding the attachment against endwise movement in either direction when the wrench is not in use. Midway of its length and upon its under face the shank 2 is providedwith a clutch'or spanner pin 12, forming an operating projection.

As shown, the wrench is mounted for free endwise movement in a cap 13, having at its inner end an externally-threaded sleeve 14, adapting it to be screwed into the internallythreaded front end of the tubular magazine 15, which it closes and for which it forms a finish. The said cap 13 is formed with a central opening 16 for the reception of the wrench attachment, which is movable freely endwise back and forth through it, the retaining-pin 6 being passed through the perforation 5 in. the trunnion 4 after the trunnion end of the attachment has been passed through the hole 16 in the cap. The button 3 then prevents the wrench attachment from being disconnected from the magazine when the attachment is moved inward, while the pin 6 prevents the attachment from being disconnected from the magazine when it is moved outward. Spannerpin holes 17 formed in the face of the cap 13, provide for screwing the cap into and unscrewing it from the magazine by means of an ordinary spanner wrench, which is not shown.

The front end of the magazine is furnished with an integral or fixed tip 18 in the form of a radial flange, the front face of which is furnished with spanner or clutch pin holes 19 for the reception of the spanner or clutch pin 12 of the wrench attachment, the rear face of the tip 18 being formed with an annular groove 20 for the reception of a tenon 21, located upon the forward end of the forestoek 22, the rear end of which is formed with a tenon 23, entering a groove 24, formed in the front face of the lower portion of the gun-frame 25, which is furnished with an internally-threaded socket 26 for the reception of the threaded rear end of the magazine 15. The magazine is also formed with an integral stop-shoulder 27, engaged by a buffer 28, engaged with the forward edge of a guidering 29, depending from the reeoiling barrel 30 and having its rear edge engaged by the forward end of the barrel-closing spring 31, encircling the magazine and abutted at its rear end on the front face of the lower portion of the gun-frame.

Normally the Wrench attachment is retired into and housed in the front end of the magazine, at which'time its longitudinal axis is parallel with the longitudinal axis thereof, as shown in Fig. 1, the attachment being held in this position by its retaining-spring 9, which engages with the wall of the opening 16 and forces, the attachment in the opposite direction, so as to cause its locking-notch 7 to be engaged with the Wall of the opening 16 at a point just opposite the point engaged by the said spring, whereby the attachment is firmly held in place. When, however, it is desired to use the attachment, the button is pushed, against the tension of the spring 8,, the position of which is always disclosed by the hole 10 in the button. This sidewise movement of the attachment enables the shoulder 7 to be cleared from the wall of the Opening 16, through which the attachment may now be pulled endwise and outward by its button until its arm 4 is engaged with the inner face of the cap 13, after which the attachment is swung at a right angle to the axis of the barrel, as shown in Figs. 2 and 3, turning upon its trunnion-like arm 1 as upon a pivot. When in this position, the attachment is prevented from becoming detached by the retaining-pin, which engages with the inner face of the cap 13. The attachment may now be swung in the plane of the cap 13 and tip 18, turning very freely upon the circular portion of the arm 4:. Now by carrying the attachment slightly outward away from the cap 13 and tip 18 its spanner-pin 21 may be engaged with any one of the spanner-pin holes 19 and readily shifted from one hole to another in the usual way of using a common spanner-wrench. When so engaged with the tip 18, the attachment constitutes a powerful wrench for screwing the magazine into the gun frame and unscrewing it therefrom. When this has been done, it is a simple matter to swing the attachment out into alinement with the magazine and then push it inwardly by endwise pressure upon its button 3 until the spring 8 acts to shift it sidewise, and so look it in place inits retired or housed position, as shown in Fig. 1.

It is apparent that in carrying out my invention some changes from the construction herein shown and described may be made. I would therefore have it understood that I do not limit myself thereto, but hold myself at liberty to make such departures therefrom as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the front end of a tubular magazine, of a wrench lil(e attachment mounted for endwise movement therein in line therewith.

2. The combination with the front end of a tubular magazine, of a wrench attachment mounted for endwise movementtherein in line therewith and provided at its inner end with a trunnion-like arm on which it turns as upon a pivot when extended and adapted at its outer end to be grasped and drawn out into its extended position.

3. The combination with the front end of a tubular magazine, of a Wrench attachment mounted for endwise movement therein in line therewith and provided at its inner end with a trunnion-like arm on which it is turned as upon a pivot when in its operating position and at its outer end with an operating-button, and means for retaining it in its retired position in which it is housed within the front end of the magazine.

4. The combination with the front end of a tubular magazine, of a wrench attachment mounted for endwise movement therein in line therewith and adapted at its ends to prevent its being disconnected therefrom and provided with a projection for operative engagement with the magazine when in its extended and operating position.

5. The combination with the front end of a tubular magazine, of a wrench attachment mounted for endwise movement in line there- 'with, and provided at its inner end with 'a trunnion-like arm, at its outer end with an operating-button, with a locking-spring for holding it 1n its retired position in which it is IIO angle to the magazine to be engaged therewith for screwing and unscrewing the same. 7. The combination with a tubular magazine formed at its front end with a collar-like tip, of a Wrench attachment mounted in the front end of the magazine for endwise movement therein in line therewith and adapted When extended and turned downward at a right angle to the magazine to be engaged with the said tip for turning the magazine in either direction.

In testimony whereof I have signed this specification in'the presence of two subscrib- 1ng Witnesses.
