SCULLING HOOK.

Application filed November 15, 1926. Serial No. 148,510.

This invention relates to sculling hooks, such as are secured to the hoisting cable of a crane and used to pull or break out sculls formed in hot metal ladles, and has for its object the provision of a novel hook construction in which removable points are provided so that a' sharp cutting edge may be maintained without the expense of forging new points on the hook.

The sculling hooks of the class to which this invention pertains are steel castings weighing several hundred pounds and have heretofore been made with integral points on the hook arms. l Vhen the integral points become dull it is necessary to handle the entire hook and forge new points, which op eration was costly due to the labor necessary to handle such a cumbersome article.

The present invention provides removable points which may he slipped loosely over the arms of the old hooks after the integral points have been cut away, thus providing a renewable structure which provides a sharp point at less cost than heretofore and in materially less time.

In the drawings:

Figure 1 is a sectional view through a ladle showing a hook constructed in accord ance with my invention engaged against a scull in a ladle. V

Figure 2 is an elevation on a larger scale of a hook embodying my invention.

Figure 3 is a top plan of the hook.

Referring more particularly to the drawings, the numeral 2 designates a ladle which has a scull 3 formed therein, with which asculling hook A, suspended by cables 4 from a hoisting element such as a crane (not shown), is engaged in the operation of breaking out the scull.

The hook A comprises a shank 5 having an eye 6 at its upper end and tapering from a point 7 intermediate its ends toward its lower end, so that the lower end is substantially twice the diameter of the upper portion.

Four hook arms 8 are formed integral with and extend radially from the lower end of the shank 5 and have a substantially equal rectangular cross-section throughout their length.

Hook-shaped point members comprising hollow sleeve-like body portions 9 and upwardly projecting hook points 10, have their sleeve-like body portions mounted over the ends of the arms 8 and are secured against misplacement by pins 11.

The forward faces of the point members are inclined outwardly and upwardly, and the rear faces 12 of the points 10 are inclined rearwardly and downwardlv so as to provide a sharpened point with a thickened base. The upper wall 14 of the body portion 9 is thickened from the rear end forwardly toward the point 10, and the bottom wall 15 is thickened from the forward end rearwardly so as to reinforce the body at the points of greatest stress when the hook is in use.

Sculling hooks to which this invention pertains are subjected to enormous strains in use and, therefore, must be made very heavy. The particular hook illustrated in the present drawings has a shank substantially siX (6) inches in diameter at its upper portion, and twelve (12) inches at its lower end, and the hook arms are substantially eight- (8) inches in length, six 6) inches high, and four l) inches wide. The point members are correspondingly heavy.

It will be readily appreciated that hooks of the size set forth above would require considerable labor and time to sharpen the points when the points are formed integral with the arms 8 as heretofore. Therefore,

the advantages resulting from the present telescopically substantially the same cross-section throughout their length, point members provided With sleeve portions adapted to slip loosely over said arms, and a pin for removably securing said point members on said arms. In testimonv whereof, I have hereunto PAUL D. WRIGHT.

signed my name.
