Application filed April 14, 1919. Serial No. 289,808.
To all whom it may concern:
Be it known that I, REX KENTLING, a citizen of the United States, and resident of Mohler, in the county of Tillamook and State of'Oregon, have invented a new and useful Safety-Hook, of which the following is a specification.
My invention relates to improvements in hoisting hooks in which two members interlock in such a fashion that a complete slackening of the hoisting chain must take place before the two members can be separated and the load removed.
One object of my invention is to provide a safe means for hoisting boiler plates and other such structural members, as are perforated near one edge. 1
Another object is to avoid the waste of time incident to the usual method of tying chains or cables around such plates or members or inserting ,clevises preliminary to the hoisting.
A further object is to provide a hook which is simple in construction and effective in application.
I attain these objects with the mechanism illustrated in the accompanying drawings in which Figure I is a side elevation of the entire hook.
Fig. II is a front elevation of Fig. I.
Similar numerals refer to similar parts throughout the several views.
The main member of my safety hook comprises a flat shank 1, an eye 2 at the upper end to connect with the hoisting chain, a hook 3 at the lower end, and a slot 4 in the shank about midway between the two ends.
The secondary member is bent of round steel in such a manner that, in front elevation, it presents the three sides in a rectangular frame of which the fourth side is formed by the main member.
Of this secondary member the upper limb 5 is pivoted slidingly within the slot 4. of the main member; being secured therein by the shoulder 6 on one side and a suitable locknut 7 on the other side. The lower limb 8, after having been inserted into one of the apertures 9 in the boiler plate 10, is laid to rest .in the hook 3 of the main member. As a further precautionary measure to make accidental disconnectionwell-nigh impossible, the limb 8 is secured against lateral slip by the end 11 being bent downward and resting against the side of hook 3. It will be evident that there is no possibility for the boiler plate to escape involuntarily.
To release the plate same must come to rest on a firm support. Then a slackening of the hoisting chain permits the main member to slide downward until the upper edge of the slot lrests on the limb 5, the secondary member at the same time being held in a more or less perpendicular position. Further slackening of the chain will cause the main member to assume the position indicated by the dotted line 12 in Fig. I, after that the secondary member may be withdrawn from the aperture 9.
For attaching the safety hook the above process is reversed, 'z'. e. the main member is brought to a right angle with the secondary member, limb 8 inserted into a suitable opening, the main member rotated to a vertical position, and a tension in the hoisting chain will interlock hook 3 with the limb 8.
Having described my invention it will be seen that my objects have been accomplished and, though I have shown the preferred form of construction, I reserve to myself the 7 right to make minor changes providing I do not violate the spirit and principle of my invention.
I claim:
2. A safety hook comprising a main member having a flat, vertical shank, an eye at the upper end, a hook at the lower end pro-' jecting upwardly from the edge of the shank, and a slot within the shank, with a secondary member having a shank disposed in a vertical plane parallel to the main member, having an upper limb pivoted slidably within the slot of the main member, and having a lower limb adapted to enter a per-- foration in a steel plate and capable of being interlockingly supported by the hook of the main member.
3. A safety hook comprising a main member having a flat shank, an eye at the upper end, a hook extending upwardly from the lower edge of the shank, and a slot in the shank about midway between the two ends, said slot penetrating the shank at right angles to the hook, with a secondary member having a round shank, an upper limb at right angles to the round shank, a 100k nut and shoulder at the end of the upper limb to secure the latter slidably and pivotally within the slot of the main member, a lower limb at right angles to the round shank particularly adapted to enter a perforation in a steel plate and having the free end interlockingly supported by the hook of said main member.
