Specification of Letters Patent.
Y:Patented Oct. 22, 1907'.
` Application filed July 23. 1907. Serial No. 385.1474
To all 'whom` it 'may coni-.1m
lie it known .hai i \\'ii.i.i.\.\i J. Devixn. a ciizenof the United Stat-cs, residing at. Norwalk. in the county of Fairfield and Stute. ot' i'onnccticut. have invented new and useful improvements in insulators, of which the following is a speciiication. i
This invention relates to insulators and more especially to blocks with cooperative parts which may be built upon each other so as to carry a number of electric wires at certain pointsand locations which have been heretofore diiiicult to arrange and carry them as will be more fully described in the following specification, set forth in the claims and illustrated in the accompanying drawings where like reference letters are used in the various views io designate the same parts.
Figure l is a perspective view of several of the blocks located 'on the corner of a beam and carrying the wires of a circuit. Fig. 2 is a cross sectional view of several superimposmh blocks through the notches which contain the wires. Fig. 3 is a vertical longitudinal sectional view of a block. Figs. 4 and 5 are views of a modified form of insulating block. Fig. 6 is a view showing how the insulators carry a wire along the ceiling and the beams o a. building.
A very serious obstacle heretofore in the strinigng of electric wires has been the turning of angles and corners and the great source of danger in electric wiring for high voltage is where the wire comes in contact with the corners of posts or beams. the covering is worn off by chaiing and short circuiting through the woodwork follows and iire often results. In order to overcome these and other objections to the common form oi block7 which are designed and constructed 4for use on [iat surfaces only, the present invention consists of a block of porcelain. rubber, glassV or other insulating material of any desired length according to the number of wires to be strung and having along its under Vside a `groove itl with two ilat sides separated atan angle of preferably ninety degrees. This groove l() is formel in the block for the purpose of locating it on the corner of posts, joists or other timbers of a building where the wiring is to be strung and the block used. Transverse to the groove l() are grooves'li which carry the wires,
andthe upper face of the block is provided with a rib i2 whose sides correspond with those of the groove l() into which it is adapted to iit and this rill also has transverse grooves iii coinciding with the grooves ii and in these grooves the wires :ire contained and clamped.
Screw holes 14 are formed vertically in the block through which screws or spikes are passed to aline the blocks, secure them to the timber and at the same time clamp the wires in the grooves 1l and i3.
in practice, a series of two or more blocks is adapted to be used. The groove of one block of the series is adapted to receive the rib of the next adjacent block, thereby providing an interlocking connection between the blocks. The groove of one ofthe end blocks of the series is adapted to receive the corner of a timber or other support to which the series is secured.
Where it is desired to use these blocks on plane surfaces, the feet formed at each side of the groove serve as a ready support and the blocks may be built up and secured hy means oi screws or spikes.
These insulators are thus serviceable in stringing wires in all directions and readily overcome the question of turning corners. v
In Figs. 4 and 5 the modified form of the block there shown is one of the round type with a groove 15 in its lower side for the purpose of securing it to the corner of a post or beam and having Wire holding grooves 16 in its upper face,v a cap 17 with corresponding grooves i7 is provided to he secured on the block hy the screw or spike i8 which not only secures it to the woodwork but grips the wire. I
It is obvious that other modified forms may beadopt-4 ed with means for securing same to the corners or the plane face of woodwork without departing from the essential features above. described.
What I claim as new and desire to secure by Letters Patent is:
l. in insulating blocks. the combination with blocks of electric non-conductive material, of interlocking means for' in testimony whereof. i aliix nu' signature in presence oi' two witnesses.
