Specification of Letters Patent.
Patented Jan. 16, 1906.
Application filed December 16,1903. Serial No. 185,357.
To all whom it may concern:
Be it known that I, FREDERICK W. Sons, a citizen of the United States, and a resident of Englewood, in the county of Bergen and State of New Jersey, have invented. a certain new and useful Improvement in Cable-Hangers, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.
This invention relates to cable-hangers such as are used to suspend electric cables.
In the accompanying drawings, in which the same reference-numerals refer to similar parts in the several figures, Figure l is a perspective view showing the application of an Fig. 2 is a plan of the hanger before being applied to a cable. Fig. 3 is a longitudinal section of the same. Figs. 4, 5, and 6 are details.
In the embodiment of this invention shown in the drawings the hanger is shown as being in the form of a strap and may be composed of a suitable strip 1 of metal or other material. Preferably sheet-zinc is used for this purpose. Suitable grips may be formed. on the hanger to more securely engage the cable, and these grips may be in the form of projections 7, formed on that portion of the hanger which when in operative position engages the cable, as indicated in Fig. 1.'
A headed stud is preferably employed to hold the parts of the hanger in position, and this stud may be formed of similar material to the hanger-strap and may be securely riveted to the strap 1. The head 14 may be formed upon this stud to securely clamp together the collar 12 on the stud and the washer 13, these parts engaging either side of the hanger strap 1 and firmly holding the stud thereto. Suitable slots are preferably formed in either end of the hanger to cooperate With the stud, and these slots may be given the keyhole form indicated, the slot 9 being formed with the enlarged opening indicated and with the smaller opening 10 at the other end of the slot, the slot 4 being preferably formed in the same manner at the other end of the hanger. Suitable lockingfianges are preferably employed in connec tion with these slots to securely lock the hanger in adjusted position, these flanges when in looking position substantially closing the intermediate portions of the keyholeslots. Fig. 6 indicates a single locking-flange 8, cooperating with one of these keyhole-slots, while in Figs. 2, 4, and 5 the locking-fianges 5 are formed on either side of the slot to cooperate therewith.
In using the hanger the head 2 of the stud is inserted through the larger opening at one end of the keyhole-slot 9 and is then moved along to the reduced opening 10, so that in this way the hanger is secured to the supporting wire or cable 15. Then when the cable 16 has been brought into position the end of 0 the hanger is brought around the same, the
headed stud inserted through the larger opening in the keyhole-slot 4 and passes up this slot to restin final position in the reduced opening 6 at the end of this slot. stud is being moved along the slot the locking-flanges are of course pressed aside to allow for the passage of the stud, and when the stud is in final position the locking-flanges are restored to their original position, so as to 7 5 prevent the accidental release of the stud, this operation being indicated clearly in Figs. 4 and 5. By rigidly and permanently securing the head of the stud to the hanger-strap a more reliable connection is secured, and, fur- 8o ther, by having the whole of the hanger formed to one metal, such as Zinc, destructive electrolytic action is avoided and a permanent, cheap, and reliable hanger is. secured.
It will be further noted that when in oper 8 ative position the weight of the cable draws upon the closed loops of the hanger, so that the headed stud is kept in the reduced openings at the ends of the keyhole-slots.
It is of course understood by those familiar with this art that many changes in the form, proportion, and number of parts of this device may be made, and, furthermore, parts may be used without employing all of the same, and parts may be used in connection 9 5 with grips and with keyhole-slots adjacent the ends of the same, a headed zinc-stud rigidly riveted to said strap intermediate said slots, there being yieldable integral lockingflangcs adjacent said slots to cooperate therewith and to prevent the accidental displace- 1 10 ment of said stud in said slots.
