SPECIFICATION forming partof Letters Patent No.r'i' 2ir52'=,v dated March 24, 1903.

Application-filedDecember'Z,1902i I Serial IIa-133,615. v(No model.)

To all whom it may concern,.-

Be it known that I, DAVID T.Y GOODMAN, a citizen of the'United States, residing at Altoona, in the county of Blair, State of Pennsylvania, have invented certain new and useful Improvements in Hooks; and I do herebyY declare the following to be a full,clear, and

exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wrecking-tackle tion being to provide a hook which may be easily and quickly engaged with the drawhead and which while retaining its place when subjected to strain may be readily disengagedVVV when desired. In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective viewshowing the hook engaged with the draw-head of a coupler. Fig. 2 is a perspective View of the hook disengaged from the coupler.

Referring now to the drawings, there is shown the draw-head 5 of the Well-known Janney coupler, having the slot 6 to receive acoupling-link when it is desired to connect with a common form of link-coupling and the perforations? to receive acoupling-pin, these perforations being formed through the laterally-projecting portions 8, upon the inner end portions of the rear faces of which are roundedlugs 9,while in the outer end portions of the rear faces are recesses 10, the lugs 9 of one draw-head being adapted for engagement with the recesses 10 of the cooperating draw-head in the manner well known to those skilled in the art.

The hook embodying the present invention comprises a stem 11, having the bill 12 at one end and the cross-bar 13 at the opposite end, the thickness of the stem being such as to permit engagement thereof in the slot 6 of 'the draw-head,at which time the ends of the cross-bar`13'which project vertically above Vand below the stem, lie against the rear faces of the portions S ofthe draw-head, and in the -frontflat faces Vof the vertically-projecting portions of the cross-bar are recesses 14, 4which receive the lugs 9, so that the crossybar is' held from slipping laterally from engagement with the draw-head. The cable for moving thecar is connected to the hook, and

'it will be seen that the greater the strain applied tothe hook the more rmly will the lug 9 engage the recess 14, while as soon as the strain ceases the hook may be pressed rearwardly and then moved laterally from engagement with the draw-head.

What is claimed is- Y 1. A wrecking-hook comprising a stem hav- Ling a bill at one end and a cross-bar at its opposite end projecting above and below the stem,s'aid projecting portions having'recesses therein.

n 2. A wrecking-hook comprising a stem having a bill at one end and a cross-bar at its opposite end projecting above and below the stem, said Yprojecting portions having flat front faces having recesses therein.

3. A wrecking-hook. co mprising a stem having a bill at one end and a cross-bar at its opposite end projecting above and below the stem, said projecting portions having flat front faces'having recesses therein adjacent to one edge of the stem.

4. A wreckingh'ook comprising a stem having a bill at one end' projecting laterally therefromLand a cross-bar at its opposite end projecting in opposite directions from the stem at right angles to the direction of projection of the bill, said projecting portions of the cross-bar having flat front faces having recesses therein adjacent to one edge of the stem.

In testimony whereof I afx nay-signature in presence of two witnesses.
