Detachable Ladder Hooks
The illustrations herewith show a detachable ladder hook invented by Herbert S. Tompkins, of Watertown, N. Y. The single, or scaling hook, can be applied to any short ladder by attaching it in the center. During the tests to which it was subjected it operated without a hitch. The double hook is especially designed for use in connection with fire work. It may also be used on ladders employed in building and other construction. It is a novel, simple, convenient and inexpensive attachment for ladders which may be converted into a root ladder without any delay or trouble. It can also be applied where ladders are too short. One of the tests of a double book was on a 30-foot ladder off the ground and with a weight of 1,157 pounds, with the hook placed on a tile cornice, when it proved most reliable. One of the cuts shows this test with the men scaling a building to the fourth story, on the 30-foot ladder, and another shows where it is used to good advantage with a life line.
