GEORGE FREUND, OF DURANGO, COLORADO.
KNIFE FOR MINERS.
:JPBCIFICATION forming part of Letters Patent No. 313.41%, dated March 8, 1885.
(No model.)
To all 211710727, it may concern:
Be it known that I, GEORGE FREUND, of Durango, in the county of La Plata and State of-Oolorado, have invented a new and Improved Miners Knife, of which the following is a full, clear, and exact description.
The object of my invention is to provide a new and improved knife for niiners use for facilitating the cutting and capping of fuses, opening cans, and for other similar purposes.
This invention',which is an improveinenton the miners knifefor which Letters Patent No. 297,375 were issued to me on the 22d day of April, 1884., consists inthe combination, with a knife-casing. of a can'opener, a cork-screw held in the blade for splitting or cutting the fuse, and in "arious details and parts of construction and combinations of the same, as will be fully described and set forth hereinafter.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a longitudinal elevation of my improved knife, showing all the blades closed. Fig. 2 isasimilar view showingthecan-opener blade opened. Fig. 3 is a view of the opposite side, showing the main blade and the fuse cutter or splitter open. Fig. 4 is a like view showing all the blades closed. Fig. 5 is a longitudinalelevation of the fuse-cutter blade, showing the same provided with aeork-screw.
A blade, A, is pivoted in a casing, 13, and is provided with a notch, O, the bottom of The easing B is provided with a corresponding notch,
' D, the bottom of which is also designed to be screw-threaded. The end of a fuse is placed in the notch D, the blade A is pressed down ward, and thereby a screw-thread is formed on the end of the fuse, thus adapting the fuse to be screwed into the cap. If desired, the fuse can be passed into the cap, and the fuse and cap placed in the notch D, and the blade A pressed down to form the screw-thread in the cap and fuse, and thus prevent the cap from slipping oii' the fuse. One end of the casing is provided with a notch, E, for receiving the end of the fuse to be split longitudinally. A blade, F, pivoted inthe casing, has a projection beyond the pivot, which projection forms the blade G for splitting the fuse.
The blade F is adapted to be folded in a recess, H, in the side ofv the casing, in the bottom of which recess a how-shaped spring, J, is held,whichis provided withaprojection, K, held in a notch in the side of the casing, thus leaving both ends of the spring J free. The end J of the spring is provided with a slight recess or groove for receiving the edge of the blade F, and theopposite end is providedwith a head, J, provided with transverse grooves and with a longitudinal groove for receiving the point of the blade F. When the blade F is folded in the recess H, it presses back the head J and passes under the same. If the blade F is to be opened, the thumb-nail is placed in one of the small transverse grooves in the head J and the said head pressed against or toward the end of the recess H, whereby the said head is moved from the end of the blade F, which is thus released, permitting the opposite end, J, of the spring J to throw the said blade outward. thus acts as a lock to keep the bladein place, and as a spring for throwing it out when re leased. Notches are formed in the blade F and in the case for cuttingthreads on smaller fuses. If desired, the blade F may consist/of a corkscrew, I, over which a casing, L, isscrewed, forming the blade. If the corkscrew is to be used, the casing L must be removed. The casing L or the blade F can be used as a spoon for digging out giant-powder candles to insert the fuse with cap.
In that end of the casing B opposite the one in which the blade A is pivoted, and at the same end as that in which the blade F is pivoted, a can-opener, M. is pivotedgvhich is pro vided. with a point, a sharp edge, and with a curved roughened part, N, to prevent the blade from slipping on the can. The part 0 of the end of the casing is also roughened, notched, or serrated to prevent the handle from slipping on the can. The can-opener blade M is pivoted by a pivot, P, passing through a slot, O, in one end of the blade M, which is also provided with an L-shaped or like slot, R, extending to the edge, through which slot a pivot or screw, S, passes. In
one side of the blade M a notch, T, is formed, which is adapted to receivea pin, U, formed on the end of a springflV, secured on the easing. WVhen the can-opener blade M is folded The spring I TOO within the casing. the pin U snaps into the notlt h T in the blade. .thus locking, the blade in place. Alter the blade M has been swung out to open it, it is pressed toward the end oftlie casing to cause thepin S to be at the upper end of the slot R for the purpose of holding the can-opener in position. ll'the can-opener blade is to he closed. it is first pulled in the direction from the end of the casing to release it, and is then folded in the casing, in which it is locked by the spring W. The can-opener blade is provided with a groove, 0, for receivin; the thumb or finger nuil for opening it.
Having thus dest-rihed my invention, what I cluin as new, and desire to secure by Letters Patent, is
1. ln a knife, the combination, with the case B. oftlte blndc llLimving the slots Q and R. and of the pins P and S in the knife ease. substantially as herein shown and described. I
2. in n knile, the combination, with the case B, having its end portion, 0, serrated or roughened, of the can-opener blade M, having part of its back edge roughened, substantially as herein shown and described.
3. iii a knife, the combination. with a handle-case having a recess in oneside, of ablade adapted to be folded within the said recess, and ot' a spring secured in the bottom of the recess and having both ends free, one end being, provided with a head having a longitudinal groove to receive the point of the blade, substantially as herein shown and described.
4. In a knife, the combination, with the case B, having a recess, H, of the spring J, having both ends tree, and provided with a projection,
K, for holding it in place, and the blade F,
pivoted in the case, substantially as herein shown and described.
GEORGE FREUND.
