CE ILIN G-HOOK.

Specification of Letters Patent.

Application filed January 28, 1909.

Patented July 13, 1909.

Serial No. 474,727.

To all whom it may concern:

Be it known that I, HENRY L. BRADLEY, a citizen of the United States, residing at New Haven, county of New Haven, State of Connecticut, have invented a new and useful Ceiling-Hook, of which the following is a specification.

This invention has for its object to provide a strong, durable and symmetrical ceiling hook, which shall be simple and inexpensive to produce, shall comprise double parallel strands throughout and shall be formed complete from a single blank of wire formed to shape and rigidly locked in place by a sheet metal clamp.

With these and other objects in view I have devised the novel ceiling hook which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to in dicate the several parts.

Figure 1 is a perspective of my novel hook complete and ready for attachment; Fig. 2 a plan view of the blank of wire formed to shape; Fig. 3 a perspective of the clamp detached; and Fig. 4 is a section on the line 4-4 in Fig. 1, looking in the direction of the arrows.

My novel hook comprises a base, two hooks depending therefrom and an attaching screw all formed integral from a single blank of wire and a sheet metal clamp by which the ends of the formed blank are securely retained in place and the hook as a whole is made rigid.

10 indicates the base, 11 the hooks which depend therefrom and 12 the attaching screw. The base is formed from the mid-length and the ends of the blank, one of the ends being left longer than the other, bent outward at a right angle to the base and pointed and threaded to form the attaching screw. The base in use lies parallel with the ceiling, stud or strip to which the hook is attached and both the base and the hooks are double throughout, the strands lying parallel. Starting with the base, for convenience in description, the parallel strands of wire which form the hooks are bent downward and then curved outward away from each other and then upward, the two strands forming each hook being joined at the outer ends of the hooks, that is the wire is bent upon itself as at 13.

It is of course wholly immaterial by what succession of steps the blank is formed to shape orwhat portion of the completed blank is formed first. The blanks may be formed to shape either mechanically or by hand. In practice I form them mechanically at great speed and at trifling cost beyond the cost of the wire. As already stated, one end of the blank is left longer than the other and is pointed and threaded to form the attaching screw. This pointing and threading operation may be performed upon the blank before the forming operation or it may be part of the forming operation, the special process of pointing, threading and forming the blank of wire being wholly unimportant so far as the present invention is concerned. The end of the blank opposite to the attaching screw is preferably chamfered off, as at 20, and partly overlaps the other end at the intersection of the attaching screw with the portion of the base formed by said other end of the blank of wire, as indicated in Fig. 2.

The clamp, indicated by 14, is formed from a blank of sheet metal. It is bent to inverted U-shape in cross section and comprises a top, indicated by 15, and depending side pieces, indicated by 16. The top is provided with a hole 17 at one side of the center, transversely, through which the attaching screw is passed.

In assembling, the clamp is placed over the base, the attaching screw passing through the hole. The clamp is then closed upon the base by means of suitable dies or a blow of a drop hammer, the top being depressed inward between the strands of wire which form the base, as at 18, and the side pieces being curved about the under side of the strands as at 19, thereby locking the overlapping ends of the blank tightly together and making the hook as a whole perfectly firm and rigid. The top of the clamp forms an ample bearing for the completed hook on the ceiling, stud or strip to which it is attached, and the grip of the clamp on the strands forming the base renders it impossible for the strands of the base to work loose under the strains of longcontinued use.

Having thus described my invention I claim:

1. A ceiling hook conr rising a base and two hooks formed from a lank of wire and a clamp formed from a blank of sheet metal, the base being formed from the mid-length and the ends of the blank of wire and the hooks depending threfrom, one of the ends being bent outward and threaded to form an attaching screw, and the clamp having a hole through which the attaching screwi s passed and being closed about the strands of the base to lock them in place.

2. A ceiling hook comprising a base and two hooks formed "from a blank 01" wire and a clamp formed from a blank of sheet metal, the base being formed from the mid-length and the ends of the blank of wire and the hooks depending therefrom, one of the ends being bent outward and threaded to form an attaching screw, and the clamp having a hole at one side of the center transversely through which the attaching screw is passed, the clamp being depressed between the strands of the base and curved about them to lock said strands in place.

3. A ceiling hook comprising a base and two hooks formed from a blank of wire, the

base being formed from the mid-length and the ends of the blank and the hooks consisting of parallel strands oined at the outer ends depending therefrom, one of the ends being bent outward and threaded to form an attaching screw and the other end being cham'fered oil and overlapping, and a sheet metal clamp consisting of a top having a hole at one side through which the attaching screw is passed and side pieces, the top being depressed between the strands of the base and the side pieces being curved about said strands to lock them in )lace.

In testimony whereol' I afliX my signature, in presence of two witnesses.
