COMBINED IMPLEMENT FOR DE'lACHlNG AND REPLACING THE PARTS OF SMALL-ARMS.

Specification forming part of Letters Patent No. 4.7,7l5, dated Ma-y 16, 1365; antedated May 1, 1865.

1'0 all whom, itmay concern:

Be it known that I, ALEXANDER GRILLET, of Philadelphia, Pennsylvania, have invented an Improved Gun Appendage; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My improved gun appendage consists of a compact instrument (fully described hereinafter) to be carried by a soldier and to be used by him for the purpose of operating on his fire-arm, the instrument being such that it can be used for withdrawing and replacing the mainspring, can be adjusted for use as a screwdriver, as a band or tumbler punch, a wrench for withdrawing and replacing the nipple, and as a medium for carrying the wiper and ballscrew.

In order to enable others skilled in the art to make and use my invention, I will now proceed todescribe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure 1 is a plan view of my gun appendage; Fig. 2, an edge view; Fig. 3, a plan view the reverse of that shown in Fig. l, and Fig. 4the same as Fig. 3 with the arms or plates open.

Similar letters refer to similar parts throughout the several views.

The instrument consists of two main plates or arms, A and B, which are hinged together at w, and which can be made toassume the two positions seen in Figs. 1 and 4.

On the outer end of the arm A is a projection, a, in which is a square opening adapted to the square portion of the cone or nipple, so that when the latter has to be screwed to or unscrewed from the gun the arm A acts as a wrench, of which thearm B forms the handle,

'the two arms being in the position shown in Fig. 4. A stud, b, is secured to and arranged to turn on the outer surface of the arm A, and from this stud project two pins, the long pin 6 consisting of a plain cylindrical rod of steel, and serving as a tumbler-punch, and the shorter pin having screw-threads adapted to similar threads in an opening in the neck of the wiper H, the ball-screw L being also screwed into the neck of the wiper.

The end or of the arm B serves as a large screw-driver, and when used as such the arm A, occupying the position seen in Fig. 4, forms the handle.

To a pin projecting from the outer face of the arm B are hinged the small screw-driver c and band-punch d, which together form, at

' the point where they are connected to the arm,

a hub or stud, 3, alluded to hereinafter.

It will be seen that two pins or studs, 1 and 4, project fronnthe outer face of the arm B, and that a stud, 2, projects from the arm A. The object of these studs and the duty they have to perform will be best observed on reference to Figs. 3 and 4, in which the main spring of the gun is shown in red lines.

When the mainspring has to be withdrawn from the lock, it is in the first instance com pressed by operating the hammer, so as to assume the form seen in Fig. 3. Theinstrument is then so applied to the lock that the studs 1, 2, 3, and 4 shall occupy the position in rela tion to the spring seen in the said Fig. 3. The hammer of the lock is then released, so that the spring may be distended and bear against and be controlled by the above-mentioned studs, when on moving the instrument away from the lock it will carry with it the mainspring, which can be readily detached from the instrument after the two arms have been moved to the position shown in Fig. 4, and the spring thereby permitted to become distended.

It will be understood withoutexplanation how the instrument can be manipulatedfor the purpose of restoringthe mainspringtothelock.

WVhen the two arms are folded together, as seen in Fig. 3, they are locked to each other, a pin, f, on one arm entering aholein the other. This lock is so light, however, and the arms are so thin that by wedging the end of the thumb between the arms near the end of the same one arm can be easily unlocked from the other.

When a ball has to be withdrawn from the barrel of a fire-arm, the ball-screw L is un-' screwed from the neck of the wiper H and attached to the ramrod, and when the wiper has to be used it can be readily unscrewed from the pin which projects from the stud b and attached to the ramrod.

When the instrument is not required for use,

the several parts occupy the relative position illustrated in Figs. 1, 2, and 3, and are con; tained in so small a space that the instrument can be carried in the pocket without incon- Venience.

The manner in which the instrument has to be adjusted to operate on the screws, band, nipple and tumbler of the fire-arm will be readily understood without further explanation.

- I claim as myinvention and desire to secure by Letters Patent- 1. The two arms A and B, hinged to each other and provided with the studs herein described, or the equivalents to the same, the whole being arranged for acting on the mainspring of afirearimsubstantially as described.
