' specification.

Similar numerals refer to similar parts in the several figures.

My invention comprises a separable hook the members of which are adapted to be sepa rated from each other for convenience in at taching the same to a suitable support and are adapted to be connected together in position for use when attached to either a V61? tical or a horizontal support.

Figure 1 of the drawings is a view in side elevation of my improved separable hook with the parts connected in position to be attached to a vertical support. Fig. 2 is a similar view of the same with the parts connected in position for attachment to a horizontal support. Fig. 3 is a top plan view of the head of the supporting and attaching member. Fig. 4 is a bottom plan View of the same. Fig. 5 is a view inside elevation of thehead portion of the same, showing the open end of the screw-driver slot. Fig. 6 is a similar view of the opposite side. Fig. 7 is a central longitudinal section of the same taken on the broken line 7 7 in Fig. 3. Fig. Sis a viewin side elevation of the hook-prong. Fig. 9 is a' front view of the same.

The device consists of two members, one of which comprises the hook-prong and the other the means whereby the hook-prong is.

attached and supported. The attaching and supporting member comprises the shank 1', which is preferably in the form of a screwthreaded stem adapted for insertion in a wall or ceiling or other supporting medium, and the head 2 integral with the shank. The head is fixed upon the end of the shank eccenlrically and is provided on its top with a screw-driver slot 3, adapted to receive a screwdriver for insertion of the screw in the usual manner. The screw-threaded stem or shank preferably underlies the slotted portion of the head, the screw-driver slot extending only slightly past the center of the head and opening at one side of the head only, as shown in Figs. 3 and 7. The'head is provided on one side with a groove 4, which intersects the screw-driver slot at its open end. The head is further provided with two apertures extending centrally thereof and intersecting each other at right angles. One of these apertures 5 extends from the bottom of the screw-driver slot to the side of the head opposite the open end of said slot, said aperture being in line with said slot and forming a continuation of the same covered by the overlying portion 6 of the head. The other aperture 7 extends axially through the head.

The hook-prong 9 comprises a'hook-shaped piece of wire having one end 10 offset in T- form, as shown in Fig. 9.

When it is desired to attach my improved hook to avertical support, the screw-shank is first inserted in such support in the usual manner of-inserting a screw and in such a manner that the cross slot or groove 4 shall be at the top of the head. The point of the hookprong is then inserted in the screwdriver slot and down through the aperture 5 in line withsuoh slot until the oppositelyprojecting T-arms on the other end of the wire enter the cross-groove 4 in the positionshown in Fig. 1. The hook-prong will thus be supported by inclosing portions of the head in such a manner that it'cau neither rotate in the head nor slip down through the same and isadapted for use as a hook for supporting garments or other articles.

When it is desired to attach the hook to a horizontal support, the screw-shank is inserted therein in the same manner, the hookprong having first been inserted through the central aperture 7 from the back side of the head, the screw being forced into the horizontal support until the offsetting T-arms on the end of the wire are engaged by such horizontal support and forced thereby tightly against the back surface oi the head and against the shank of the screw, which is slightly flattened, as at 8, to .l'orni a bearing therefor. The parts will thus occupy the position shown in Fig. 2, in which the hookprong is adapted to serve as a hook for supporting various articles.

The hook-prong can be turned to occupy either the position shown by solid lines or that indicated by dotted lines in Fig. 2 before the screw is driven fully to its seat.

The shank of the Supporting and attaching member may he of any known form adapted to be, attached to the wall or ceiling.

What I claim as new, and desire to secure by Letters Patent, is-

1. A separable hook comprising in combination a shank adapted to be inserted in a suitable supporting-body, and provided with an enlarged eccentric head having an aperture located centrally of the head and outside the body of the shank and a hook-prong inserted through said central head'apertnre and detachablysecu red therein, substantially as described.

2. The combination with a screw-threaded shank having an enlarged head and provided with a screw-driver slot extending, from one side of the head approximately to the center thereof; and a hook aperture extending through the unslotted part of the head; of a hook inserted and detachably secured in said hook-aperture, substantially as described.

A separable hook comprising, a supporting-shank, a head provided with two hookapertures one at right angles to the other; and a hook adapted to he detachably secured in either of said apertures, substantially as described.

4-. A separable hook comprising in combination a screw-shank and head, said head being provided With a screw-driver slot opening at one side only of the head, a cross-groove in the side of the head intersecting the screwdriver slot at its open end, and an aperture extending centrally through the nnslotted portion of the head from the inner end of the screw-driver slot to the side of the head oppo site said cross-groove and a hook-prong adapted to be inserted in the bottom of said screw driver slot and in said aperture and having an offset end adapted to enter and fit said eross-gr0ove, substantially as described.

In testimony whereof I have hereunto set my hand this 7th day of April, 1899.
