ELECTRICAL/FUSE BLOCK.
Application filed August 31, 1926', Serial No. 132,7177 and in Australia October 2, 1925.
This invention relates to electrical fuse blocks and has tor its object to provide a block whereby the binding means for the electrical fuse wire will be insulated Vtrom each other and whereby also the electric lead wire connectors will be insulated from each other and from said binding means, and whereby turn ther the block may be used for the purpose of allowing ready inspection ot the fuse wires, and for permitting ready replacement ot same without damage to a workman attending to such replacement.
r1"he fuse block is constructed ot insulating material; it is made in three separable parts adapted to be placed together to torni a unitary structure, and providing' means tor attachment to the fuse bloclr of lead wires, binding means, and fuse wire.
Referring to the accompanying drawings in which the invention is illustrated, Fig. 1 is a perspective view ot the fuse block; Fig. 2 longitudinal section on plane 2 2 of Fig. 1; Fig. 3 view showing the separate parts of the fuse block segregated; and Figs. 4, 5, 6 and 7 respectively transverse sections on lines 4 4, 5 5, 6 6, and 7- 7, Fig. 2.
The base 1 of the fuse block is constructed oi suitable insulating material. 1t may be provided with openings 2 and recesses 3 whereby itmay be appropriately connected to any approved support. One side ot the base 1 may be furnished with a rib or flange 4 and on opposite sides of said rib or tiango are situated the metal conductive members 5 and 6 adapted to have secured thereto the binding screws 7 and 8 whereby electric conductive wires may be attached thereto. The members 5 and 6 are secured to the base 1 by means of electric conductive screws 9 and 10', such screws being in electric conductive relation to the conductor plates 11 and 12 which are respectively suitably attached to the U or like springy conductors 13 and 14 which are arranged in conductive relation to the tapped conductive sleeves 15 and 16 of the respective binding screws 17 and 18 for the fuse wire 19.
Said base 1 is provided with three separate chambers 20, 21 and 22. The conductor plate 11, binding screw 17, the sleeve and the spring conductor 13 are located in the chamber 20, whilst the conductor plate 12, the binding screw 18, the sleeve 16, and the spring conductor 14 are located in the chamber 21.
Adapted to lit on the base 1 is the cover 23 provided with recesses whereby the fuse wire 19 may be passed from the binding screw 17 in the chamber 2() to the chamber 22 and t'rom thence to the chamber 21 and the binding screw 18. Said cover has formed integrally therewith a projection which is capable of entering the chamber 22 of the block 1 in such manner that the fuse wire 19 will be below such projection 25 when the cover 23 is set on the block 1 (see Fig. 2).
An inspection plug 26 is adapted to tit within a recess in the cover 23, said plug carrying a sprmgy member 24 capable of fitting an opening 27 in the projection 25. The member 24 may consist ot a split pin.
Associated with the respective sleeves 15 and 16 are screws 28 and 29 whereby the said sleeves with their associated binding screws 17 and 18 for the fuse wire 19 are attached to the cover 23. The heads ot' such screws 28 and 29 are countersunk in the cover 23 and the countersunk portions of said cover may be filled with electric non-conductive sealing material.
When the parts ot' the fuse block described and shown in the drawings are assembled they make a unitary structure, the cover 23 being removable from the base 1 and the plug 26 being removable from the cover 23. Upon current lead wires being connected to the screws 7 and 8, current is tree to pass to the elements 5 and 6 and from thence through the screws 9 or 10 and thence to either of the plates 11 or 12 and from thence to the respective U-connectors 13 or 14, trom whence the current may flow either to the sleeve 15 or 16, to either the binding screw 17 or the binding screw 18, the fuse wire 19 being connected to both screws 17 and 18. i
Should the wire 19 become fused the plug 26 may be removed from the cover 23 and the said fusing may then be inspected. Should it be desired to replace a wire 19 which has become fused it is only necessary to remove the cover 23 from the base 1, and in such removal the fuse wire 19, the screws 17 and 18, sleeres 15 and 16, and screws 28 and 29 will be withdrawn with the cover 23. A person may then replace a fused wire 19byanew fuse wire without it being necessary to disconnect the electrical lead connections to the binding screws 7 or 8 or disturbing the current switch connections for said lead connections.
What I claim as my invention and desire to secure by Letters Patent is 1. An electrical fuse block, comprising a base having three separate compartments, a removable Cover for the base having a proj ection disposed in one of said compartments and an opening communicating with the spaces on opposite sides of the said projection, a removable inspection plug for said opening` binding means carried by the cover and projecting into the other two compartments, and
10 a fuse element attached at its ends to the binding means and projected into the compartment occupied by the said projection.
2. An electrical fuse block, as claimed in claim 1, in which the inspection plug is removably attached to the projection by means of a spindle split at one end to expand in the projection and threaded at the other to screw into the plug.
In testimony whereof I affix my signature.
