Specification of Letters Patent.
Iatented March 20, 1906.
Application filed July 20,1904. Serial No. 217,324.
, vide an improved terminal clamp for holding the end of the fuse, one which is compact, strong, and inexpensive, which enables the fuse to be quickly replaced Without moving the cover of the box, and is located well back in the field of the blow-out magnet to insure the extinguishment of the arc in case the fuse I should burn up entirely.
In the accompanying drawings, Figure 1 is a perspective view of a fuse-box with the cover removed, showing my improved terminal clamps; and Fig. 2 is a section of one of said clamps.
The box 1 is made of sheets and strips of insulation, such as fiber suitably fastened together. Its bottom is open to permit the escape of the arc when the fuse blows. At each end of'the box in theupper corner is secured a terminal clamp consisting of a block 2, having a transverse hole 3 to receive the conducting-lead and cut away at one side to form jaws 4, which cooperate with a wedge 5, operated, preferably, by a screw 6. The wedge preferably constitutes the nut with which the screw meshes, the screw having a smooth shank 7, rotatable in a bearing in the block. A handle 8, of insulation, is secured to the shank outside of the box and has a large cylindrical body 9, rotatable in a somewhat larger opening in the end of the box. A loose washer 10, of insulation, surrounds the shank 7 between the body 9 and the block 2. A detent is provided to prevent the screw from becoming accidentally loosened. This is plunger 11, sliding radially to t e screw in a socket in the lower part of the block. The plunger is bored out to receive a helical spring 12, which, abuts against a screw plug 13, forming the bottom of the socket. The head of the plunger is square to engage with flattened faces 14 on the shank of the screw. A fixed collar 15 on the screw stands inside of the plunger and prevents the screw from preferably a moving outwardly when the wedge is being backed out of the jaws.
Below each block 2 is a guard of insulation 16, fastened to the end of the box and covering the lower end of the block. This guard assists in su porting the block and also protects the block and the screw-plug in case of an excessive arc.
The fuse 17 is a strip of copper or the like turning the handles so as todraw the wedge into the jaws.
When a fuse blows, the magnetic field bends its ends backward and downward. If the fuse burns clear to the terminal, the arc will then be in a strong field and short-circuiting is prevented. The position of the pole-piece on the cover is indicated by dotted lines in Fig. 1. \A new fuse can be-inserted without taking off the cover of the box, since the wedges are operated from outside the box. This enables the cover to be permanently f astened on in the shop, so that the joint between the box and its cover can be made tight enough to prevent the escape of an are through said joint, a precaution which is necessary in using heavy currents to prevent short-circuiting.
What I claim as new, and desire to secure by Letters Patent of the United States, is-
1. The combination with a fuse-box of insulation, of two clamping terminals, each comprising a block of metal having jaws, a wedge cooperating therewith, an operating device for said wedge extending to the outside of the box, and locking means for said operating device. j
2. A clamping-terminal for a fuse, comprising a metal block provided with jaws, a wedge entering between said jaws, a screw engaging with said wedge and having a smooth shank rotatable in a bearing in said block, a shoulder on said screw, and a' projection carried by the block adapted to engage said shoulder.
3. Aclampin -terminal for afuse, comprising a metal bloc provided with jaws, a wedge entering between said jaws, a screw engaging with said wedge and having a smooth shank rotatable in a bearing in said block, and a detent engaging with said screw.
4. A clamping-terminal for a fuse, comprising a metal block provid ed with jaws, a wedge entering between said jaws, a screw engaging whose ends are inserted between the lower jaw and the wedge and clamped tightly byto 5 with said wed e andhaving a smooth shank rotatable in a eanng in sa1d block,.flattened faees on said screw, and-a spring-plunger engaginiwith said faces.
