LINE-WIRE CONNECTOR.

Specification of Letters iatent.

Patented Aug. 20, 1918.

Application filed September 11, 1917. Serial N 0. 190,859.

To all whom it may concern:

Be it known that we, JAMns OoNDoN KEENAN and MICHAEL HENRY KEENAN, both of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Line-Wire Connectors, of which the following is the specification.

Our invention relates to improvements in line wire connectors and the object of the invention is to devise a connector by which a line wire may be connected to an insulator, which will have a maximum strength and to which the line wire is connected without the use of any tool thereby obviating any danger of abrading the line wire and thereby weakening it and it consists essentially of the following arrangement and construction of parts as hereinafter more particularly explained.

Figure 1, is a perspective view of our connector showing a portion of a line wire connected thereby to an insulator.

Fig. 2, is a similar view to Fig. 1, looking at the reverse side.

Fig. 3, is a plan view.

Fig. 4, is a perspective detail of our connector.

In the drawings like letters of reference indicate corresponding parts in the various figures.

1 indicates an ordinary insulator by which the line wire 2 is carried, the insulator 1 being provided with the usual annular groove 1. 3 indicates our connector which is formed by a central band portion 4 curved longitudinally so as to fit into the groove 1*. Each end of the band is provided with a wing extension 5, which are bent longitudinally into the form of a split sleeve 6, the approaching edges of the sleeves being turned outwardly into lips 6 and 6, the inner end of the uppermost lip being curved upwardly at 6 to form a V- shaped leading-in opening leading into the split of the sleeve. V

A reinforcing web 8 is formed extend-la between the lower edge of the end of the band 4 and the lower edge of each sleeve 6.

When it is desired to put our connector in place it will, of course, be understood that the line wire 2 is stretched taut and extends past the insulator l opposite the Copies of this patent may be obtained for groove 1". The band 4 is placed around the insulator and the line wire 2 carried into the V-shaped space formed by the upturned lip portion 6 thereby separating the split of the sleeve 6 and allowing the line wire to enter the split and spring into place within the sleeve, which then closes tight therearound. When this portion of the line wire is in place the line wire is drawn into the groove 1 by hand and carried over the sleeve on the opposite side of the insulator and into the V-shaped recess of the sleeve upon the corresponding side of the insulator. It is then released and the tension of the wire then serves to force the split of this sleeve apart and allow the wire to enter into the sleeve, which then springs together thereby gripping the line wire on that side of the insulator, 7

It will be understood that in the ordinary way of connecting a linewire to an insulator a Wire is wrapped around the line wire at each side of the insulator by a tool, such as pliers. This operation tends to injure the line wire by being abraded or cut into by'the tool and thereby weakened so that when the wire is subjected to unusual strain, such as when carrying ice or snow, it is liable to snap at this point.

In placing our device in position no tool is necessary and, therefore, the wire remains uninjured.

It will also be seen that our connector will be of maximum strength, the band 4 giving increased width to that part going around the insulator. The webs 8 prevent any danger of the sleeve-like portions splitting away from the ends of the band.

What we claim as our invention is.

In combination with an insulator a line wire connector comprising a pair of split sleeve-like portions having the split edges of the sleeves formed into out-turned lips having their inner ends turned up to form an entering recess, and an interconnecting band extending between the inner ends of the sleeves and adapted to fit into the groove of the insulator.
