To all whom it may concern:

Be it known that l, FRANK A. MGGREGOR, a citizen of the United States, residing at Grafton, county of Allegheny, State of c Permsylvania, have invented a new and useful Improvement in Carriers for Percussion Caps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming partof this specification, in which- Figure 1 is a perspective view of an improved carrier constructed in accordance with the present invention, and I Figure 2 is an end elevation of the com is struction illustrated in Figure 1..

The present invention relates broadly to special receptacles and packagcs,'and more particularly to a carrier for crcussion or et/onating caps such as use by miners,

so quarrymen and the like, for setting ofi explosive charges.

At the present time the use by miners of caps of this nature is regulatcdvery strictly. A miner is not permitted to use, durin a as single day, more than five such caps, an is not permitted at an time to have on his person any more t an five caps, under penalty of a heavy fine. It is quite customary for miners to carry these caps loose- 80 ly in their ockets with the result that contact of the ody of the miner with electric conductors frequently sets ofi' thepaps, there being annually hundreds of deaths resulting from such explosions.

The present invention has for one of its objects the construction of a carrier'by means of which the number of caps allowed by regulations may ,be expeditiously carried without endangering the life of the miners.

- M In this manner the casualties may be materially decreased and inspection of miners equipment facilitated.

Referring more particularly to the drawin there is indicated a carrier comprising w a bid 2 of any desired material. I have found that wood is admirably adapted to this purpose, although it will be apparent that other materials may be employed. The upper (portion of the carrier is provided with a ovetailed groove 3extendin through one end of the carrier and adapted to slidably receive a cover 4. The dovetailed joint between the carrier and the cover prevents the entranceof moisture to the interior of the carrier, and the cover may be held firmly in closed latch 5.

Below the groove 3 a portion of the carrier is cut away to provide a chamber 6. Adjoining this chamber is a solid portion 7 of the carrier having formed therein a lurality of pockets 8, the number of poo sets preferably corresponding to the number of percussion caps which a miner may legally have in his possession. These pockets are preferably arran ed in. such manner as to communicate at t leir upper portions with a passage 9 forming a communicating con-v gection between the pockets and the chamer 6. I

Each of the pockets 8 is preferabl of a. depth slightly 1n excess of the lengt of a percussion cap, whereby, it demired a small amount of cushioning material, such as cotton, ma be placed in the bottom of each of the poo ets. The caps may then be slipped into the pockets with the lead-in Wires con= ncctcd thereto extending throu h the pas sage 9 and coiled in the chain or 6. The cover 4 is then slid into position to securely hold the caps in place and prevent any damage thereto. If the carrier is constructed of insulating material, contact of the body of the miner with current carrying conductors will not set ofi the caps. Where wood, or other similar material is used, it will preferably be protected with a. coating of such material as asphaltum to increase both its insulating and water-proofing properties llt will be understood that where the carrier is being used with percussion caps not provided with lead-in wircs, thc chamber 6* and the passage 9 may be omitted. It will also be apparent to those skilled in the art that changes may be made in the construction of the carrier without departing from the's irit of the invention or scope of my broa or claims.

The advantages of the present invention its arise from the provision of a carrier for controlling the number of caps being carried iii-accordance with the regulations and for protecting the caps against accidental ex losion.

claim:

1. As an article of manufacture, a carrier for percussion caps comprising a main body portlon having a pocket therein for the reception of a cap, and having" a chamber for no position by mcansof a suitable the reception of the cap wires, there being a communicating passage between the pocket and the chamber, substantially as described.

2. As an article of manufacture, a carrier for percussion caps comprising a main body portion having a pocket therein for the reception of a cap, and having a chamber for the reception of the cap wires, substantially as described.

3. As an article of-ma'nufacture, a carrier for percussion caps comprising a main body ortion having a plurality of pockets therein for the reception of caps, and having a chamber cooperating therewith for the reception of the lead-1n wires for said caps, there being a passage communicating with all of sai poo ets and with said chamber, substantia ly as described.

4. As an article of manufacture, a carrier for percussion caps comprising a main body ortlon having a plurahty of pockets therein for the reception of caps, and having a chamber cooperating therewith for the re ce tion of the lead-in wires for said caps,- su stantially' as described.

5. As an article of manufacture, a carrier for percussion caps comprising a main body portion having a pocket therein for the reception of a cap, and having a chamber for the reception of the cap wires, there being a communicating passa e between the pocket and the chamber, an a cover remcvably weenie cooperating with said body portion, sub- I stantially as described.

6. As an article of manufacture, a carrier for percussion caps comprising a main body portion having a pocket therein for the reception of a cap, and having a chamber for the reception of the cap wires, and a cover removably cooperating with said body portion, substantially as described.

7. As an article of manufacture, a carrier for percussion caps comprising a main body portion having a plurality of pockets therem for the reception of caps, and having a chamber coo crating therewith for the reception of t e lead-in wires for said caps, there being a assage communicating with all of said poc rets and with said chamber, and a'cover removably cooperating with said body ortion, substantially as described.

8. Es an article of manufacture, a carrier for percussion caps comprising a body ortion having a restricted number of poo ets therein for the reception of caps, there being a passage communicating with the u per portion of all of said pockets, said ody portion having a chamber communicating with said passage, a cover for said carrier,

and means for holding the cover in closed 00 position, substantially as described.

In testimony whereof I have hereunto set in hand.
