Application fled Aprll 1!, 1917, serial Io. 181,098. mowed October 9, 1918, Serial 10. 880,641.
To all w'hom'it may concern:
Be it known that I, Ronmrr P. YOUNG, a subject of the King of Great Britain, residing at Montreal, rovince of Quebec, Canada, have invented certain new and useful Improvements in Refillable Fuses; and I do hereby declare that the following is a full,
clear, and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same.
The present "invention relates to fuses and an object of the, resent invention is to provide a casing or older for fuses which may be readily assembled or disassembled in placing and removing the fusible wires therefrom. a 4 v With the above and other objects in view which will hereinafter appear as the description continues, the invention consists of the novel features of construction combination and formation of parts as will be hereinafter more fully .described and particu-- larly pointed out in the appended claims.
In the accompan rawin Figure 1 is a vertica longitu a1 section through the fuse embodying thgresent invention; Y
Fig. 2 is a cross section through the same taken on the line 22 of Fig. 1;
Fig. 3 is a dibled perspective view I of the casing; and,
Fig. 4- is a'detail perspective view of the.
cover for the casing.
The invention will be best understood from a consideration of the following detailed descriptiomtaken in connection with the accompanying'drawin forming part of this specification, with t e further understanding that while the drawings show a partial form of the invention, the 'latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departurefrom the salient features of the invention.
Like and corresponding parts are indicated by similar reference characters throughout the several views.
The casing comprises an elongated tube 1 of preferably cylindrical configuration having its opposite ends opfned and being preferably made of fiber, ut, of course, it can be made of any other suitable insulating disassembled so that the fuse wire 10 may replaced thereby increasing the life of the to the inner face of the cover plate 2 is a' mica sheet 3- preferably arcuate in cross section having its opposite sides projecting be- Patented Nov. 23, 1920. 7-.
yond the cover plate 2 and these projections are adapted to rest within the casing 1 forsecuring the cover plate in place. In placing the cover plate upon the casing the same is inserted at one end thereof and moved along until the ends of the cover lie flush with the ends of the casing and the mica plate 3 prevents the cover plate from being withdrawn. The opposite ends of the easing are adapted to be closed and incased by means of the caps 4 preferably made of brass. Secured to the o posite ends of the cover plate 2 by means 0 the bolts 5 are the brackets 6. The shank portions of these bolts 5 project beyondwthe cover late and are provided with the nuts 7. he caps 4 are provided with the slots 8'for rewiving the shank portions of the bolts 5, thereby preventing. the cap;
the casing 1. xtending through the medial portion of the caps 4 and adapted to be brou ht into threaded engagement with the brac ets 6 are the set screws 9. When the cover plate is inserted into position, the caps are placed upon the ends of the casing and the set screws 9 secured in position the caps will be prevented from being removed and the cover plate locked in position. The bolts 5' also secure the brackets 6 upon the cover plate 2 and each of the shank portions of these bolts are provided with openings through which projectthe opposite ends of the fuse wire 10 and these bolts 5 are pro vided with T ends which are'adapted to rest upon the opposite ends of the wire 10 for securely locking the same into position.
"From the foregoing it is obvious that by providin a sectional casin such .as described, t e same may be readi y assembled 8:
fuse. \Vhen the fuse has been assembled as shown in Fig. 1 and it is desired to replace the fusible wire 10 one of the set screws 9 and a cap 4 may be removed and the cover plate slidably removed from the casing, thereby presenting the fuse wire to ready access so from being rotated upon that it may be removed and a new one substituted therefor. The cover plate may then again be inserted in place and the set screws tightened so as to connect one of the caps a to one of the brackets 6, thereby securely locking the same into position and, again presenting the fuse for use.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A. fuse comprising a casing, a longitudinally slidable member arranged in said casing and forming a part thereof, means for connecting said slidable member to said casing and a fuse wire detachably connected to said slidable member.
2. A fuse comprising a casing, a plate slidab y mounted in said casing and forming a section thereof, means for connecting said plate to said casing and a fuse wire detachably connected-to said plate.
3. A fuse comprising a casing, a longitudinally slidable element adapted for location within said casing, and closing one side thereof, means connected to said slidable element for retaining the latter within said casing and a fuse wire detachably connected to said slidable element.
4. A fuse comprising a tubular casing, a
longitudinally slidable member connected to said casing and closing one side thereof, brackets. secured to said member, means for detachably connecting said member to said casing, a fuse wire detachably connected to said brackets and means for securing said brackets to said slidable member.
' 5. A device of the class described comprising an elongated casing, a longitudinally slidable segmental member connected to said casing and forming a side closure therefor, brackets secured to said segmental member, 'a fuse Wire 'detachably connected to said brackets, end caps for inclosing the opposite ends of said casing and segmental member and means whereby upon the removal of one of said end caps, the said segmental membermay be adjusted to expose said fuse. 7
6. A device of the class described comprising a tubular easing, a se anental member adjustably connected to said casing and forming a side closure therefor, brackets secured to the opposite ends of said segmental member, fuse detachably connected to said brackets, caps inclosing the ends of said casing and adapted for preventing the movement of said adjustable member, and means whereby upon the removal of one of said caps, the said segmental member may be adjusted to expose said fuse.
7. A device the class described comprising a tubular casing, a segmental member capable of longitudinal adjustment within said casing and forming a closure from one side thereof, brackets secured to a fuse detachably connected to said brackets, caps arranged upon the opposite ends of said casing and segmental member, means for connecting said brackets to the segmental member, means for securing the fuse to said brackets, and means for detachably connecting said segmental member to said casing.
