' FIREARM LOCK u Filed Sept. 3, 1941 2 Sheets-Sheet 2 Inventar Camille Parker Attori/e] Patented Aug. 17, 1943 UNITED STATES PATENT 0I-Fl FIREARM LOCK v Camille Parker, Montague City, Mass. Application September 3, 1941, Serial No. 409,410 4 Claims. (Cl. 42-1) 'I'he present invention relates to new and useful improvements in rearm locks particularly for guns, revolvers, automatic pistols, etc., and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which will positively prevent loading of the firearm.

Another very important object of the invention is to provide a lock of the aforementioned character comprising novel means for maintaining the bore of the barrel of the firearm in a clean, well-lubricated condition.

Other objects of the invention are to provide a rearm lock of the character described which will be comparatively simple in construction, strong, durable, highly eilicient and reliable in use, compact and which may be manufactured,

at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in vertical longitudinal section through a lock constructed in accordance with the present invention, showing the device in use on a revolver, portions of the latter being broken away in longitudinal section to reveal the invention.

Figure 2 is a view in side elevation of the lock.

Figure 3 is a top plan view.

Figure 4 is a view in front elevation of the device. y

Figure 5 is a view in rear elevation of the block or body which is mounted on the forward end portion of the firearm barrel.

Figure 6 is a perspective view of the rear end portion of the rod constitutlnga portion of the device. Y

Figure 7 is a view in longitudinal section through a modification.

Referring now to the drawings in detail, it will be seen that reference numeral I designates a body or block of suitable metal, said body being substantially oval in cross-section, as shown to advantage in Figures 4 and 5 of the drawings. The body I has formed in its rear end portion a socket 2 for the reception of the forward end portion of the barrel 3 of a revolver 4. A longitudinal slot 5 in the upper portion of the body I communicates with the socket 2 and accommodates the sight 6 of the revolver Ii. Thus, the

body I is positively secured against rotation on the barrel 3. Y

Extending longitudinally through the upper portion of the body I and slidably adjustable therein is a bolt or rod 1 of suitable metal. The rod I is adapted to extend through the barrel 3 into the chamber 8 of the cylinder 9 of the revolver 4 which is aligned with said barrel. An oiled cover I 0 of felt or other suitable absorbent material is provided on the rod 1 for keeping the bore of the barrel clean and for preventing rust. Qn the forward end of the rod 'I is a roughened head I I.

The head II is removable.

Mounted on the rear` end portion of the rod 'I is a thimble I2 which is engageable in the chamber 8. Extending into the thimble I2 from the rear end thereof are slots I3 for the reception of a cross-pin I i which is mounted on the rear end portion of the rod 1. Thus. the rod 'I is connected to the thimble I2. Stop flanges I5 on the rear end of the thimble I2 are engageable with the corresponding end of the revolver cylinder 9.

The forward end portion of the rod 'I has milled therein a series of notches or recesses I8.. Mounted in the forward end portion of the body I is a cylinder lock VI'l which is operable by-a key I8. 'I'he bolt I9 ofthe lock I1 is engageable selectively in the notches, or recesses It, for positively securing the rod 1 against longitudinal movement relative to the body I.

It is thought that the manner in which the device functions will be readily apparent from a consideration of the foregoing. Briefly, the rod l positively prevents rotation of the revolver cylinder 9 and also renders it impossible to load the chamber of said cylinder which is-aligned with the barrel 3. When the device is used on -other types of firearms loading of the breech is prevented by the presence of the thimble I2 therein. To remove thelock the bolt I9 of the cylinder lock Il is disengaged from the rod 1 and head II is removed. 'I'his permits the body I to be slipped forwardly off the rod 'I, after which the thimble I2 withdrawn rearwardly from the gun. 'I'he con-V struction and arrangement is such as to substantially prevent dirt, water, etc., from getting into the barrel 3 of the iirearm. Further, as hereinbefore indicated, the oiled cover I 0 keeps the bore of the gun barrel thoroughly lubricated.

Inthe modification illustrated in Figure 7 of the drawings, an adapter sleeve 20 has a thimble 2l pressed thereinto. Therear end portion of the thimble 2I is longitudinally slotted. as at with the rod 1 may be ldevice may be successfully 22, to accommodate the pin Il. Then, the rear end portion ot the sleeve 20 is provided with an external stop flange 23. By the use of thimbles of various thicknesses or external diameters the used on guns of different calibres.

It is believed that the many advantages of a rearm lock constructed in accordance with the present invention will be readily understood and although preferred embodiments o! the device are illustrated and described. it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

l. A rearm lock comprising a rod for insertion through the barrel of a, ilrearm, a thimble on one end portion of said rod engageable in the ring chamber of the rearm, said thimble having slots extending thereinto from its rear end, a cross-pin on the rod engaged in the slots for connecting said rod t0 said thimble, and means for anchoring the rod in the barrel. A

2. A firearm lock comprising a rod for insertion through the barrel of a rearm, means for anchoring one end portion of said rod in the tiring chamber of the nrearm, a body having a socket therein for the reception or the torward end portion of the barrel, th rod extending slidably through said body, and means in the body for locking the rod thereto against relative sliding movement.

3. A rearm lock comprising a rod for insertion through the barrel oi a rearm, means on one end of the rod for anchoring said rod in the firing chamber of the rearm, means for anchoring said rod in` the barrel, and an absorbent lubricating sleeve on the rod for insertion in the barrel.

4. A firearm lock of the character described comprising a body having a socket therein forthe reception of the forward end portion of a rearm barrel. said body further having a slot therein communicating with the socket for the reception of a sight on the barrel, a rod insertible through the barrel and extending through the body, means for anchoring one end of the rod in the firing chamber of the firearm, and means for locking the other end portion of the rod to the body.

CALDLLE PARKER.
