P031 13) 01 ALBERT F. IDAUM AND E. ii
LQIOQSSE,
To an whom it may concern:
Be it knownthat we, PAUL 11 GOLDMANN and ALBERT F. DAUM, citizens of the United gntates of America, residing at Pittsburgh, 21 the county of Allegheny and State of .rennsylvanis, have invented certain new end useful Improvements in Fuses, of which the following is a specification, reference being had therein to the accompanying drsw- 111g. I
Our invent-ion relates to improvement in fuses and more particularly to structures capable of bein refilled. v I;
Among the o jccts of our invention {1) to provide a structure in which the fuse element ufey act as a. retaining device for plugs prior to the placing of the end cap in position; (2) toprovide a structure in which the seating of the end cap acts to pro ide e Wiping contact with the fuse element; (3}
to provide a structure in which the fuse ele ment is held in contact with the end cap gardless. of the expansion and contraction can be readily refilled, and which of the shell cerryirigthe fuse; (4) to pro-- vide a, structure in which metallic contact other than that provided by the fuse element is substantially eliminated; (5) to pro" vide a structure in which it is substantially impossible to provide a cutting (ill of the fuse at the point of contact.
Further objects are to provide svstructure which is simple and eilicient in operation, employs s minimum number of parts, which can be manufactured and installed at e relatively low cost. I
To these end other ends, the natur of which will be readily understood as the invention is hereinafter disclosed, our invention cousists in the improved construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims.
In the accompanying drawings in which similar reference characters indicate similar parts in each of the views ll igure is central, longitudinal sectional view taken through one form of our fuse, one oi the plugs being shown. in elevation. Fig. 2 is on end View of the fuse with the cup re moved. Fig. 3 is a side elevation of one of the plugs. Fig 4 is a perspective view of the same. Fig.

modified form of plug.
The fuse carrier or cartridge forming the sub ect matter of our present invention comprises s tubular member 10, preferably of insulating material, such as fiber, glass, or
material, said member being preferably screw-threaded exteriorly at its ends, end being relatively smooth interiorly throughout its length.
11 designates an end plug, two of which are "preferably employed, being substantial duplicstes. The preferred form of plug is that shown in l to 6 inclusive, in which scoped, sud provided with radial slits 12, extending from the rear to the opposite end of cone-shaped portion, these slits Serving to divide this portion into parts which, under pressure, may yield slightly inwardly member 10 preferably having its ends slightly reamed out to permit a closer fit at this point, although this is not absolutely eutly appear. The remaining portion of the plug is preferably-tapered in the opposite direction, as at 13,-siid is provided intermediste the ends of such tapered portion with an annular groove 14 of less depth thee normal thickness of the fuse Wire to be employed in connection with the fuse, seid plug is also provided with an" axial diametrically of the plug and leads in werdly from the outer end thereof to .a point in proximity to the inner Wall of the groove terior configuration approximating that of the tapered portion. of the plug, with the exccptionbf the groove and kerf, said cap being intcriorly screw-threaded. us at 18, to permit it to be secured to the threaded portion of the member or shell 10, the parts being preferably arranged so that when the end cap is in position, the interior tapered Wall of the cap will be spaced from the tapered exterior oi the )lug to present a metsllic contsct'between t e plug and cap.
