JOHN DONALD GIBSON, F SWAIQTHMORE, PENNSYLVANIA, ASSIGNOR, BY MESNE AS- SIGNMENTS, TO BRYANT SERVICE, INC.
EXPLOSIVE MARKING DEVICE.
Application filed November 1, 1923.
The object of my invention is to provide a device for projecting dies by means ofan explosive force so as to cause the dies to mark steel and other hard metallic parts.
The invention is especially adapted for use in permanently marking metallic parts of' automobiles with the makers number, or that of an insurance company, so as to make it difficult to obliterate a number in case of theft.
By my invention, the dies are arranged in series and are driven into the metal simuftaneously.
In the accompanying drawings:
Fig. 1 is a side view of my improved device for projecting dies into objects to be marked;
Fig. 2 is a plan view;
Fig. 3 is a longitudinal sectional view;
Fig. 4 is a transverse sectional view on the line 4-4, Fig. 3;
F ig. 5 is a detached perspective view of the stock frame;
Fig. 6 is a detached perspective view of the barrel frame;
Fig. 7 is a perspective view ofone of the dies;
Fig. 8 is a detached one of the cartridges;
Fig. 9 is a plan view of a modification of the invention;
Fig; 10 is a side view of the same; and
Fig. 11 is a view of one of the dies used in the modification.
Referring to the drawings, 1 is a stock frame having a hand hold 2 and an extension 3, to which the barrel carrying the frame 4 is pivoted. Mounted in the breach piece of the stock frame 1 is a series of firing pins 5, shaped as shown in Fig. 3. Piv otally mounted in the frame is a hammer 6, which has lateral projections 7 that act upon all of the firing pins.
8--8 designate heavy springs for actuating th hammer when released by the trigger 9, which is pivoted to the frame at 10! perspective view of Serial No. 672,112.
11-11 designatea series of barrels that are mounted in the barrel frame 4, as shown. Each barrel has an opening 12 some distance from its outer end to release the gases. In each barrel is a rib 13 that is held in place in any suitable manner. The die 14 has a groove 15 to receive the rib 13, which prevents the die turning in the barrel. As the dies are designed for use in numbering objects, it is essential that they be arranged so that the number will be properly positioned.
The barrel frame 4 is attached to the stock frame 1 by a pivot pin 16 and a draw pin 17. On removing the draw pin 17, the device can be broken and the barrel frame can be turned on the pivot to expose the breach of the barrel. allowing for the insertion of he cartridges 18 and the removal of t e shells.
()n the barrel frame 14 is a pivoted yoke 19. which is. arranged to be passed over and to engage a projection 20 on the stock frame 1. This yoke holds the upper portion of the barrel frame iii-position. 1
Each d e 14 has a head 21 and istapered at the opposite end 22. as shown. in this end. the numeral. or other character. that is tobe impressed in an object-is located. as shown in ig. 7.
Inorder to hold the dies in place in the barrels before firing. spring-pressed plungers 23 are located in the frame 4 and project into each barrel a sufficient distance to engage the tapered portion of each die.
lVhen a die is projected, the plunger is de-' pressed.
24 designates a safety rod. which pro ects bevond the ends of the barrels. A spring 25 is located between a shoulder 26 on the rod and the barrel frame 4. This rod entra es a lever 27. which locks the trigger. I Vhen the rod is pushed in. so that the ends a of the barrels rest upon the object. the lever 27 is disenga ed from the trigger and the device can be fired.
In the present instance. the barrel frame 4 has two extensions 28. which are shaped to engage standard articles to be impressed, such as the front and rear axles of an automobile. By providing these extensions. the device can be held rigidly 1n P S tlQ hi e be ng fired.
The operation is simple. The dies, having the predetermined numerals thereon, are placed in the device, as shown in Fig. 4. The cartridges are also located, one in each barrel. WVhen the two frames are locked together, the barrels are brought in contact with the object to be numbered. The extensions of the frame hold the barrels in position. The safety rod 2 1 is pushed back, releasing the trigger, which is pulled thereby releasing the hammer, which fires all of the cartridges simultaneously, causing the dies to be projected into the article. As soon as the dies pass the openings in the barrel, the spent gases escape. In the present instance, each die makes a recess in the object and the numeral is raised within the recess. 1
Figs. 9 and 10 illustrate a modification, in which a single cartridge is used in connection with a series of dies. 1 is the stock frame, 46* is the barrel frame, which is pivoted to the stock frame at 16. In the barrel frame is a single chamber 30 for a. cartridge 18 and a series of chambers 31 for the heads 21 of the dies 1 1 which are made as shown in Fig. 11. Back of the series of chambers is a transverse explosion chamber 32, which communicates with the cartridge chamber 30.
Pivoted at 33 to the frame 4? is a barrel block 11, which has a series of chambers 11 in line with the chamber 31. This block is held in position by pins 34. Between the block 11 and the barrel frame is a space 12*. The dies 1 f are of a length to bridge this space, as shown in Fig. 9-. The chambers 11 in the barrel block 11 are less in diameter than the chambers 21 so that the heads 21 of the dies will come in contact with the block and will limit the movement of the dies. Each die has a groove 15" therein. Extending into each chamber 11 is a pin 13 which acts as a guide for the die.
In this instance, the cartridge is preferably charged with nitro-cellulose as the explosive. When the cartridge is fired, the dies are projected simultaneously. When the heads of the dies pass into the space 12, the spent gases escape into the space.
From the foregoing description it will be clear that each barrel 11 may be considered as constituting a cylinder carried by the frame 4. The spaces in communication with the respective barrels for holding the passages 18 may be considered as receivers in communication with the barrels and the same may be said of the space for the cartridge 18. as shown in Figs. 9 and 10. The rear ends of each tool member 14, as shown in Figs. 3 and 7 and the heads 21, as shown in Figs. 9 to 11, may be considered as pistons movable in the aforementioned cylinders and adapted to be acted upon by the explosive force of the cartridge in the cooperating re ceiver. Each cylinder has an opening or port between its ends, which is so located as to be uncovered by the piston as it moves out.

18. The method herein described of marking objects which consists in placing an explosive charge adjacent a die formed with a definite predetermined configuration at its operative end, and .exploding said charge to force said die against the object to be marked.
19. The method herein described of marking objects by explosive action, said method consisting in arranging a series of dies having numerals or other symbols, placing an explosive charge back of the dies, and exploding the charge to cause the dies to penetrate the object and impress the numbers or othersymbols thereon.
