Description
UNITEfi STATES FRANK M. BURTON, OF SAN ANTONIO, TEXAS.
FUSE CARRIER.
Application filed April 28,
i To all whom it may concern:
Be it known that I, FRANK BURTON, a citizen of the United States, residlng at San Antonio, in the county Bexar and State of Texas, have invented new and useful Improvements in Fuse Carriers, of which the following is a specification.
This invention relates to fuse holders and aims to provide a holder whloh carries a number of fuses, capable of being brought into proper position to provide a fresh fuse in the event of the burning or blowing out of one of the fuses.
Another object is the provision of a fuse holder having therein a removable fuse carrier, so that should all of the fuses become useless, the carrier may be removed and a new one substituted.
Another object is the provision of a fuse holder which carries a plurality of fuses held under strong tension, means being provided upon the casing whereby a fresh fuse may be moved into position after the one which has been in use has burned out.
Other objects and advantages of the 1nvention will appear as the following description is read in connection with the accompanying drawings.
In the drawings:
Figure l is a perspective view of a fuse holder embodying the present invention.
Figure 2 is a sectional view.
Figure 3 is a plan view.
Figure 4 is a sectional view on the line 4@ 4 of Figure 2.
Figure 5 is a similar View on the llne 55 of Figure 2.
Figure 6 is a sectional view with the top of the casing removed.
Figure 7 is a sectional view on the line 7 7 of Figure 3. v
Figure 8 is a detailed perspciitzre view of the fuse carrier or spool.
Referring to the drawings in detall, wherein like characters of reference denote corresponding parts, the fuse holder comprises a casing 10, formed of suitable insulating material, one end of the sald casing being provided with a threaded metallic thimble 11, by means of which the casing may be movably positioned for use. I
ne end of the casing is open, as shown and extending through its opposite end is a pin 12, the outer end of the pin serving as a contact terminal, which engages the rece1ving socket in the usual manner.
Specification of Letters Patent.
Patented J an. 31, 1922. 1919. Serial No. 293,078.
The pin 12 extends approximately the entire length of the interior of the casing and has slidably and rotatably mounted thereon a sleeve 13, which is provided with a finger 14 disposed parallel to thepin 12. Mounted upon the pin 12 between the sleeve and the bottom of the casing is a coiled spring 15, one end of this spring being secured to the sleeve and its opposite end to the pin, the casing or other permanent or stationary support. By this means the sleeve is capable of both yielding longitudinal and rotary movement upon the p1n.
slidably and rotatably mounted upon the pin 12 1s a spool 16, one end of the s 001 being formed of suitable insulation and indicated at 17. This end is provided with a notch 18, which is adapted to receive the finger 1 1 when the spool is placed upon the pin. The opposite end of the spool is formed of a metallic disc 19, which is connected to the insulated end 17 by means of a metallic connecting sleeve 20, the pin 12 being received within this sleeve.
The metallic connecting sleeve 20 extends through the disk 19 and extending radially from this sleeve to the outer edge of the disk is a strip of metal 21. The outer end of this strip is located adjacent one end of one of a plurality of fine wire fuses 22, the opposite ends of these wires being connected to the insulated end 17 of the spool. Positioned above the ends of the remaining fuse wires 22 are lugs 21 the purpose of which will be hereinafter explained.
Extending radially into the interior of the casing 10 is a metallic finger 23, the latter being connected to the sleeve 11 through the medium of a suitable conductor 24.
In assembling the device, the spool is positioned over the pin 12, so that the finger 14 enters the notch 18, the said spool being then rotated against the action of the spring 15 until the notch 18 is brought into register with the radial finger 23. The spool is then further depressed against the spring 15, so that the insulated end 17 of the spool will pass the radial finger 23, whereupon a further rotation of the spool will cause the said finger to engage the upper face of the said insulated end in a manner to permit of the rotation of the spool but to hold the same against outward movement. For the purpose of determining the proper position of the notch 18 for the depression of the spool, there is provided a notch 25 in the disc 19,
face of this disc.
the said notch registering with the notch 18 inthe opposite end of the spool. The face of the disc 19 may be numbered to distinguish the fuse strips'22 and the amperage of the fuses may be also imprinted upon the The upper end of the casing is removv ably covered by a lid or closure 26, which is the lugs 21 so as to act as a stop and prevent rotation of the fuse carrying spool, due to the action of the spring 15. Connected to the guide 31 is an insulated button 34, which serves as a means for moving the finger 33 inward, so as to disengage the latter from the lug of the burned fuse strip. Should this be necessary, both of the discs 27 and 28 are provided with registering openings 35, Which are closed by means 'of a mica disc whichis clamped between both of the insulated discs. This provides a sight opening, by means of which the fuse carrier may be seen to determine the condition of the fuses.
In the event of one of the fuses being blown or burned out, the tension of the spring 15 will cause a rotation of the fuse carrier after the finger 33 has been moved from engagement with the remains of the burned fuses, this rotation being stopped when the next perfect fuse engages the said finger, whereupon the circuit will be again established. a
The cover or lid is removably held in position by means of a spring arm 37, the inner ends of which are pivoted to the casing, as shown. The open end of the casing cover is provided with a lip 38, so that the lid will always be properly positioned upon the cas- 1n lfhe invention is susceptible of various changes in itsforms, proportions and minor details of construction and the right is here-- in reserved to make such changes as properly fall within the scope of the appended claims.
Having described the invention, what is claimed isa 1. A fuse holder embodying a casing formed of insulating material, a rotatably mounted spring actuated fuse carrier therein, a plurality of fuses carried thereby, a cap for said casing and movable means carried by the cap and engageable with the fuse carnor to hold the latter against rotation.

4. A fuse holder embodying a casing formed of insulating material, a rotatably mounted spring actuated fuse carrier therein, a plurality of fuses carried thereby, a stop for each fuse, a cap for the casing, movable means carried by the cap and located in the path of the fuse stops and capable of operation to permit of rotation of the carrier.
5. A fuse holder embodying a casing formed of insulating material, a rotatably mounted spring actuated fuse carrier therein, a plurality of fuses carried thereby, a cap for the casing, and movable means engageable With the fuse carrier to hold the latter in position.

7. A fuse holder embodying a casingformed of insulating material, a pin located therein, a spool mounted for rotation on said pin, fuses carried by the spool, a spring actuated slidab ly mounted rotatable collar carried by. the pin, means for detachably engaging the collar and spool and a stop projecting within the casing and engaging the spool to prevent sliding movement, a cap for said casing and movable means also projecting into the casing for engagement with the spool to hold the latter against rotation.
