Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed February 6, 1907. Serial No. 355,976..

To all whom it may concern:

Be it known that I, HoRA'rr'o B. HoLLIrmLn, a citizen of the United States, residing at Washington, in the District of Qolumbia, have invented certain new and useful Improvements in Attachments for Small-Arms, of which the following is a specification.

The long practice requisite for becoming an expert marksman usually involves a heavy expense for ammunition,'and further necessitates using much time in going to and from suitable places for practice and in noting carefully the result of each shot at a distant target.

The general object of this invention is to save much of the time and money thus expended, although it is notsupposed that all actual practice on the range or in the gallery can be dispensed .with. b

The invention involves the use of inexpensive apparatus that can be readilyattached, temporarily, to ordinary small arms to enable the marksman to practice at home and thereby to acquire certain of the primary requisites of a good marksman.

More specifically, the apparatus involves the use of a needle or other target-marking device which is projected beyond themuzzle of the weapon by the force of the firing pin, or the like, when the trigger of the unloaded weapon is pulled, the target to be marked usually being a miniature one fixed alittle in front of the weapon.

In the accompanying drawingaFigure 1 is a side struction of the attachments shown in connection with the barrel in Fig. 3. Fig. 7 shows another modification freely in the'shell and in case therod should move so far forward as to pass out of the aperture in the shell,

. of the devices to be used at the muzzle end of the barrel.

Inthese views, A represents the barrel of a common army rifle, A the front sight upon the same, and B the firing pin actuated in the usual way by means not shown, when the trigger O is pulled. In the cartridge chamber of the barrel is placed an unloaded shell D, of usual form, having fixed in the place of the ordinary projectile an:axially perforated plug D which may be of wood or other suitable material; Inthe plug, slides a small ibd E which extends rearward a short distance through the rear end of the ,shell in line with the firing pin. Upon the rod, near the rearend of the shell, is fixed a guiding disk and stop E- which slides guides it again into the perforation-upon itsreturn. Between his disk and the plug D isa light spring F which resists the advance of the ,rod. The rod extends forward nearly to the muzzle of the gun and at its end it is provided with a block E which moves freely in the barrel. Obviously when, by pulling the trigger, the firing pin is shot forward, it strikes the rear end of the rod and impels the latter suddenly forward, the spring returning it to position an instant later- Over the. muzzle of the gun is slipped a closely fitting cup-like member G which is slotted on its upper side to receive the front sight A, the latter thus fixing accurately the angular or rotary adjustment of the cup. I

- The bottom of the cup is centrally perforated for the extends downward and then forward in a direction parallel to thebarrel. The rod E on passing through the bottom of the cup turns downward to apoint below the barrel, then extends rearward, parallel to the barrel,

for some distance, then doubles upon itself and passes forward again parallel to the barrel,- through the arm H,

and finally terminates a little in the rear ofthe free end of the arm, in a sharp point E which the arm prevents from doing or receiving injury. The cup may be removably .secured to the barrel, if desired, by any suitable means fixing it to the barrel or the sight. The block E being normally in contact with the block E when the latter is shot forward by the firing pin, as already described, the block E and the rod E are impelled forward positively to the same extentlahd are then carried forward by momentum through nearly the whole distance allowed by the bend in the rod, the

any suitable support. The sub-target is so placed that when the gun is properly aimed at a more distant target, the point E alincs with the center of the sub-target; whence it follows that error in the aim will cause a corresponding deviation from such alinemcnt.

From the construction, it is evident that the whole apparatus may be quickly attached to or removed from the rifle without in any Way disfiguring the latter.

Fig. 5 shows the rod E, corresponding to the rod E as unbent, thearm H being omitted. This construction'has the disadvantage of compelling the use of a very small sub-target, in order that the line' of sight to the main target may not be obstructed.

Fig. 6 shows a construction in which the shell D is omitted, a disk E corresponding to the disk E being made to fit the cartridge chamber, and the two parts E E 'ot the rod being detachabiy connected, by a. threaded sleeve or otherwise.

Fig. 7 showsa detached block K provided with-a point K, to be used instead of the devices shown in Figs. 1, 2, 3 as borne by the muzzle end of the gun. In this case, the block is shot forward by the impact of the block'E and is replaced by hand. I I

Other modifications in construction may be made without passing beyond the proper limits of my invention.

What I claimis:

1. The combination with a rigidrou adapted to be- 2. The combination with a sliding rod adapted to be' slidingly mounted in the rear portion of the bore of a gun in the path of the firing pin, of a spring to resist the forward sliding of the rod under the-impact of the firing pin, asecond' rod adapted to besiidingly mounted in the forward portion of the bore in alinement with the first rod and provided with a target piercing point at the muzzle end of the gun, and a spring yieldingly resisting the forward movement of the second rod.

3. The combination with a gun and a siiding.rod mounted in the rear portion-of the bore in the path of the firing pin, a second rod mounted in the front portion of. the bore, normally abutting the first rod and provided with a target piercing point oifset laterally from the axis of the rod, and a spring yieldlngly resisting the advance of the second rod.

4. The combination with a gun, of an unloaded shell fitting the cartridge chamber and provided with a longitudinally perforated plug fitting the bore in front of said chamber, a rigid rod sliding in said plug and extendrated cup detachably secured over the muzzle of the gun and provided with a forwardly extending arm beloyv the bore, of a sliding rod lying in the perforation inthe cup, extending rearwardly in the barrel, and having a forwardly projecting offset portion in front of the gun,

a spring resisting forward movement of said rod, and means whereby the advance of the firing pin lmpeis said rod forward. I

6. In target practice attachments for small arms, the

combination with a gun, of a rigid lateral projection detachablyfixed to the barrel between its ends and adapted to engage a suitable rigid support and ,hold the muzzle of the gun at a substantially constant. distance from a sub-target while leaving the -'gun free to be aimed, substantially as set forth. V

.In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
