4 Claims.
This invention relates generally to attaching devices and more specifically to devices for securing ground wires and other electrical conductors o wood poles and other supporting structures, the predominant object of the invention being to provide an improved attaching device of this type which is of such improved construction and arrangement that it is capable of performing its intended function in an improved and highly efiicient manner.
Fig 1 is a perspective of the improved attaching device.
Fig. 2 is a perspective illustrating the improved attaching device as it appears when it has a conductor associated therewith and is being driven into a pole or other structure.
Fig. 3 is a cross-section taken through a part of a pole into which one of the improved attaching devices has been driven with a conductor associated with the attaching device, the attaching device being in the condition it assumes when the associated conductor has been seated against the pole but before the final operation of bending parts of the attaching device about the conductor.
Fig. 4 is a view similar to Fig. 3 but showing the attaching device and the conductor associated therewith as they appear when the operation of securing the conductor to a pole with the aid of the attaching device has been completed, in this view also a fragment only of the pole being shown.
In the drawing, wherein is shown for the purpose of illustration, merely, one embodiment of the invention, A designates the improved attaching device generally. The attaching device A is formed from a section of flat material, metal, for instance, and said section of material is shaped as shown in Fig. 1. In other words, the section of material of which the attaching device is formed includes a portion I of slightly tapered shape, said portion I being of slightly less width at its outer end than at its opposite portion, and formed integral with the portion I and extended from the wider portion thereof is a portion 2 which is pointed so as to facilitate the operation of driving the attaching device into a pole P or other structure. At the junction of the portions l and 2 of the device A the section of material of which said device is made in oppositely notched, as designated by the reference character 3 in Figs. 1 and 2, and portions of said section of material at opposite side edges of the device are bent outwardly slightly in opposite directions, in the direction of the thickness of the section of material, to provide prongs 4. The prongs 4 perform the obvious function of preventing outward displacement of the device when it has been driven into a pole or other structure (see Figs. 3 and 4).
The portion I of the device A is provided with a tongue 5 which is formed integral with the section of material of which the device A is formed, said tongue being formed by slitting said section of material to provide an opening 6 of the appropriate size and shape, as shown in Figs. 1 and 2, and then displacing from said opening the material encompassed therein to provide a tongue which is integral at its lower end with the section of material of which the device A is formed. The tongue 5 is so shaped that it includes an outwardly, inclined portion 5a which extends from the point at which said tongue is integrally connected to the section of material of which the device A is formed, a curved portion 5b at the outer end of said inclined portion 5a, and a straight extension 50 which extends from said curved portion 51).
In the use of the improved attaching device A disclosed herein the tongue 5 may be sprung outwardly to permit the conductor 0 to be introduced into place between the tongue and the portion I of the device A, either before commencement of the operation of driving the device into a pole P or other support, or after said device has been driven a slight distance into the pole or other support as shown in Fig. 2. The outer edge la of the portion I of the device is then subjected to hammer blows to drive the device into the pole or other support until the conductor C is seated against the outer face of the pole or other support as shown in Fig. 3. As the device A moves into the pole, as a result of the hammer blows applied thereto, a camming action is set up because of sliding movement of the outer face of the inclined portion 5a of the tongue relative to a portion of the pole or other support, and this camming action causes the conductor to be gripped between the tongue and the portion l of the device A when said conductor has been seated against the outer face of the pole or other support as shown in Fig. 3. Hammer blows are then applied to the extension 50 of the tongue and to the outwardly extended end portion lb of the portion l of the device A to bend and shape said portions 50 and lb in opposite directions about the conductor C as shown in Fig. 4 to securely attach the conductor C to the pole P or other support. When the free end portion of the tongue 5 is cammed toward the flat section of material I as described above the outer end portion of the extension 50 of the tongue is extended into the opening 6 of said flat section of material I, as shown in Fig. 3, and when the outer end portion lb and the extension 50 of the tongue 5 are bent about the conductor, as described, the bent tongue extension is seated in the opening 6 of the flat section of material I.
I claim:
1. An attaching device adapted to be driven into a support to secure an electrical conductor thereto, said attaching device comprising a flat section of material, a tongue struck from said flat section of material and formed integral therewith at an end of said tongue, said tongue including a portion of angular disposition providing a cam face which slidingly engages a portion of a support into which the attachin device is driven to move the free end portion of the tongue toward said fiat section of material of the attaching device, and an angular extension extended from the free end of said angular tongue portion, and a pointed end portion formed on said flat section of material to facilitate the operation of driving the attaching device into a support.
