. hooks, and has as .a particular object the provision of a simple and handy tool tia lly reduces the time, bother, and uncertainty ordinarily required and suffered in driving such screws. My invention works with equal facility to drive screw-hooks or any-other type of screw having a thin head in extension of the threaded portion of the screw, and its advantages for such operations as driv-ing c'up-hooks in the underside of apantry shelf will be hereinafter obvious.

further object of invention a tool .for the 'above-stat edpurposes which may in litssimplest orm bef tt'ed .to a screw-driver,

either of the simple rigid typeor of the .rathet or quick-acting type so that may be used advantageously by professional carpenters as well as by housewives and less skilled persons.

Still {another *obieot :oi myin-vention is to provide a tool tor driving 'eye screws withattached hooks which receives and guards the hooks so that an unwary person is not injured thereby.

Another =dbject is to provide a tool which holds an ye-screw firm-1y in rolong tion of the axis or the tool, so that the eye-screwfmay be started by tapping or -applying pressure to the tool. I

. its broad-characteristics,my ihvention 'comprises anelongated body in one end "a pair of transverse grooves, a-t aright angle one to another and forming a recessed cross at the center pf the body end. one of the grooves is shilow'er than the other andhas av bottom, the V being" deeper and more acute towards the "center of the body so as to grip'firmly the extension of a screw such as an eye or a cup-hook. The other groove may be broader and rounder, to form a recess for receiving the eye of a hook engaged with the eye of a screw. The end of the body opposite to said grooves may have a slot to receive the end of a screw-driver, or the body itself may serve as a handle to provide twisting leverage. If the body is enlarged for the last named purpose, the second mentioned deeper groove may be extended along one side of the body to receive the hook-portion of a driven article.

In the accompanying drawings, illustrative of preferred and modified embodiments of my invention,

7 Having reference now to the details of the drawing, {I have shown Figs. ;1 to 6 a driving tool having an elongated body .H and having its baseyend l2 cleft by .a slot 13 suitable tor receiving 9 the blade of ascrewedriver. The bifiurcated portions of the base end I2 forming the slot l3 preferably have small v-iianges 4, shown in Fig. 4, to prevent .a, screwdriver blade from slipping out of the-slot. The opposite end A5 of the-body H .is

preferably flattened to be substantially oblong in cross-section as shown in the end view of Fi 3, and ai s-doubly .forked'. .A-deep groove [6 traverses the end :15 in its lesser dimension to form one fork-. flheagroove l6 is'of su-fiicient width to hold a body attached -to ;an-eye=screw such as the eye of a hook, without ;binding thereon, and as it is not intended to bind it -may have a rounded or flat bottom Ii. Centrally traversing the end l5 inits longer dimension to vform {a. second fork and crossing the groove "5, is a shallower groove I8,

which may be somewhat narrower than the groove 16 so as to hold the eye of a screw slidably but without material play. The grooves l6 and I8 jointly form a deeply recessed cross in the end 0 IS. The bottom of the groove I8 is sloped so as to be deepest at its intersection with the groove 16 and is formed with V-notches I9 which are widest at the exterior ends of the groove and narrowest at the points where the groove I8 is 5 intersected by the deeper groove [6.

To drive an'eye-screw with this tool, the eye of the screw is placed in the shallow groove l8 and pressed firmly so that the V-notches l9 may grip the rim of the eye. If a, hook, also having 5 an eye, is interlocked with the eye-screw, the eye of the hook is placed in the deeper groove 16, permitting the hook to extend laterally from the body II. With the blade of a screw-driver inserted in the slot I3, the screw-driver may be Fig. 3 is a top, end view, in the orientation of tapped or pressed to start the eye-screw and may then be rotated to drive the screw. Because the V-notches l9 engage spaced points on the rim of the eye of the screw and the threaded body of the screw is in axial prolongation of the body ll, both torque and end-pressure are evenly applied and there is little tendency for the screw to tilt while it is being started. Instead of having to guide and support the screw with one hand while applying torque with the other, the operator handles only the screw-driver and may have one hand free. Obviously the groove |6 may hold the hook of a cup-hook as Well as it holds the eye of a latch hook.

In the modified form of my invention shown in Figs. 7 to 10, the body 2| has the general form and dimensions of an ordinary screw driver handle, so that it may be used without an auxiliary tool if desired, although its base end 22 may also be provided with a slot 23 for receiving an auxiliary tool such as a screw-driver. Starting near the end 22 and extending to-the opposite end 25, is a groove 24, which becomes progressively deeper as it approaches the end 25 until it connects with the bottom 27 of a deep diametrical transverse groove 26 at the end 25, corresponding in function to the groove l6 heretofore described. Preferably the body 2| has sufiicient thickness at the end 25 to permit the groove 26 to receive the eye of an attachment to the eye-screw-such as the eye of a latch-hook-without emerging through the Wall of the body 2| opposite to the groove 24, thus afiording wall strength to the forked end 25. A shallow diametrical groove 28 in the end 25 crosses the groove 26 at a right angle, and is bottomed in V-notches 29, the groove 28 and notches 29 corresponding in form and function to the hitherto described groove l8 and notches 9, and likewise forming a deeply recessed cross in the end 25. Near the end of the groove 24 nearest the base end 22 is a hole 30 extending radially inwardly from the bottom of the groove.

In view of the described operation of the preferred form of my invention, the operation of this modified form will be obvious. The groove 24 and hole 30 permit the shank 3| of a hook 32 to be placed in the groove 24 in parallel relationship to the body 2|, rather than radially, and to be held there conveniently by placing the point 33 of the hook in the hole 30. Thus the hook is never in the way, and the operators hands are protected from possible injury by the hook. The eye 34 of an eye-screw 35 will be firmly engaged in the notches 29 of the groove 28, to hold the screw in axial prolongation of the body 2|. The

eye 34 interlocks with the eye 36 of the hook 32 at the intersection of the bottom of the groove 28 with the groove 26, but the hook is so held by the grooves 26 and 24 that it exerts no disturbing torque upon the eye-screw.

As further modified body forms of my invention may be developed without departure from the spirit of my invention, I do not wish to be limited to the precise examples herein described, but desire the scope of my invention to be interpreted as commensurate with the appended claims.

I claim:

1. In a tool for driving eye-screws and like articles, a body having a groove bifurcating a portion of said body and having a second and deeper groove intersecting said first-mentioned groove; the walls of said first-mentioned groove being convergent adjacent the bottom of said groove to grip an article disposed in said groove at positions on opposite sides of said second groove, the bottoms of said first-mentioned groove at said positions being substantially normal to radii of a circle having its center within said first-mentioned groove in the plane of said intersecting groove.

2. In a tool for driving eye-screws and like articles, a body having a groove bifurcating a portion of said body for receiving the eye portion of a screw, and having a second groove intersecting said first-mentioned groove at substantially a right angle so as to form a deeply recessed cross, said second groove being deeper than said first-mentioned groove to receive an attachment to said eye portion and extending away from said recessed cross along a side of said body to receive a shank of said attachment.
