THOMAS DOYLE, OF ELDORADO, ILLINOIS.
SAFETY SUPPLY-BOX AND POWDER-MAGAZINE.
Application filed December 19, 1911.
To all whom it may concern:
Be it known that I, THOMAS DOYLE, a citizen of the United States of America, residing at Eldorado, in the county of Saline and State of Illinois, have invented new and useful Improvements in Safety Supply- Boxes and Powder-Magazines, of which the following is a specification.
The present invention relates to safety powder magazines and supply boxes designed for use in mines.
In carrying out the present invention, it is my purpose to provide a safety powder magazine or supply box which shall be absolutely fire roof, and at the same time render the filling of the cartridges or shells, used in the mining industry, easy and safe in loading.
Furthermore, I aim to provide a device of this character which shall include among other features a powder magazine capable of containing a quantity of powder and adapted to feed or discharge the same into the cartridge or shell in such a manner as to prevent the ignition of the powder accldentally.
The invention has for another object the provision of a powder magazine which shall render the feeding of the powder automatic and direct the same into the cartridge or shell without permitting the powder contacting with the atmosphere.
With the above and other objects in view which shall appear as the description progresses, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the appended claims.
In the accompanying drawings wherein has been illustrated the preferred embodiment of the invention; Figure 1 is a front elevation of a safety supply box constructed in accordance with the present invention. Fig. 2 is a transverse section on the line 22 of Fig. 1. Fig. 3 is a broken perspective view showing the interior of the box. Fig. 4 is a detail perspective view of the powder magazine. Fig. 5 is a broken sectional view of a part of the magazine, and Fig. 6 is a perspective View of the detail of the invention.
The loss of life and limb and other disastrous results are often brought about in the mining industry in the filling of blasting cartridges. Heretofo-re, in the filling or Specification of Letters Patent.
Patented Feb. 18, 1913.
Serial No. 666,772.
charging of blasting cartridges, the powder has been poured into the same in an open manner thereby rendering the powder liable to explosion incident to the proximity of the miners lamp and electric spark or igniting devices which are at all times lying promiscuously about the mine shafts and levels where the charging of the cartridges is carried on by the miners for blasting purposes. By means of my invention, these dangers are eliminated and the powder is fed from the magazine into the cartridge or shell, in what may be termed, a closed condition, that is the charging of the cartridges may be carried on without permitting the powder passing through the atmosphere, or what is usually termed an air gap, previous to its entering the cartridge.
Referring to the drawings in detail in which similar reference characters designate like parts throughout the several views, the supply box, in the present instance, consists of a substantially rectangular receptacle 1 provided with hooks or other suitable fastening devices 2 so that the box may be sup ported in a convenient position within the mine. This box 1 may be constructed of steel or any other material suitable for the purpose and is preferably lined interiorly with asbestos to render the same fire proof. One side of the box 1 provides a magazine compartment in which is secured a powder magazine or container 3 which latter is also rendered fire proof by means of any suitable material and has its upper end flanged as at 4 to receive bolts or other fastening devices so that the powder magazine may be supported within the box 1 and suspended from the top wall thereof. The upper ends of the walls of the powder magazine 3 are preferably beveled inwardly of the powder magazine as at 5 so as to receive a correspondingly shaped cover 6 pivotally connected to the upper wall of the receptacle 1 through the medium of hinges 7 and designed to be fastened to the receptacle by means of a suitable locking mechanism so as to close the powder magazine, the cover 6 being rendered fire proof as are all other exposed parts of the box. The powder magazine 3 is provided with a tapering bottom 8 having a discharge opening controlled by a slide 9 which, in the present instance, is movable laterally of the powder magazine and adapted to slide in suitable guide ways 10 formed upon the opposite sides of the discharge opening of the said magazine. This slide 9 normally closes the discharge opening of the magazine and is designed to be operated manually to facilitate the discharging of' powder from the magazine. In the device illustrated, the slide 9 is actuated to its normal or closed position through the medium of a plurality of yieldable elements 11 which act upon the slide to close the discharge opening, the said slide being provided with a suitable handle 12 so that the same may be slid outwardly of the guides 10, to permit the flow of powder from the magazine, against the action of the yieldable elements 11. The lower extremity of the tapering bottom 8 of the magazine terminates a suitable distance above the lower wall of the receptacle 1 and is provided with a laterally projecting flange 13 adapted to slidably receive a plate 1 1 having a conveniently located opening 15 arranged in alinement with the discharge opening of the magazine and designed to have communication therewith in the outward movement of the slide. The edges of the plate 14 are bent upon themselves to provide grooves 16 adapted to receive the flange 13 so that the plate 14: may be operatively associated with the bottom of the magazine. Connected to the lower surface of the plate 1 1 and in open communication with the opening 15 therein, is a powder conveying tube 17 arranged at a downward inclination to the plate and terminating exteriorly of the receptacle 1 so that in the opening of the slide, powder may be discharged from the magazine and gravitate through the tube 17 and into a cartridge or shell. The free extremity of the tube 17, that is the end of the tube projecting beyond the casing 1, is of such diameter as to enable a cartridge or shell to be positioned thereon so that the powder is fed directly from the magazine into the cartridge thereby insuring safety and eliminating the passage of the powder through an air gap. The cartridge-receiving end of the tube 17 may be constructed of glass or other suitable transparent material, if such is desired, to enable the miner to gage the amount of powder being fed to thecartridge, or if it is deemed desirable, the slide 9 may be constructed in a manner to permit the feeding of a predetermined amount of powder from the magazine. By virtue of this structure, it will be seen that the powder is fed automatically to the cartridge and directly into the same thereby obviating dangers from miners lamps igniting devices and the like, in'the charging of the cartridge. The opposite side of the receptacle 1, that is the interior of the receptacle adjacent the powder magazine, is designed to hold paper, or other suitable material, used for retaining the powder within the cartridge, and as shown this side of the receptacle is provided with a depending bracket 18 between which and the end of the receptacle is supported a roll of paper 19.
Conveniently supported within the receptacle, in proximity to the roll of paper, is a knife 20 secured at one end to the bracket 18 and having its opposite end fastened to the end wall of the casing -1. An auxiliary roll of paper 21 may also be supported in suitable brackets within the receptacle, if such is deemed desirable.
The front wall of the receptacle 1, at one side of the magazine receiving portion of the said receptacle is provided with an enlarged opening 22 designed to permit access to the interior of the receptacle and through which the slide 9 may be operated for the purpose described. This opening 22 is preferably closed through the medium of a hinged door 23 adapted to be securely fastened in its closed position through the medium of a hasp 24 hingedly connected to the top of the receptacle 1 and extending the full height of one side thereof and around and on to the bottom of the receptacle where it is locked in any suitable manner, thus securely holding the door in closed position.
From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.
I claim:
1. A device of the class described comprising a receptacle, a powder magazine within the receptacle, an inclined powder conveying tube, a detachable connection between said conveying tube and powder magazine, means for controlling communication between the powder conveying tube and the powder magazine, said powder conveying tube extending outwardly of the receptacle and being provided with a cartridge receiving portion whereby the powder may be supplied to the cartridge in an air-tight condition.
