Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
For apparatus for Tightening Rigging; David Stackpole, Portland, Cumberland county, Maine, October 10.
This machine is intended for setting up, or tightening, the shrouds and other rigging on board of vessels. It consists of an iron screw that plays into nuts, supported in an iron frame. The screw has a hole through the head of it, in which to insert the lever by which it is to be turned; its length must be regulated by the nature of the service it is to perform. One of these instruments is to be fixed to every shroud, or stay. The bottom end of the frame is to be attached to the chain plates, and the head of the screw to the shroud, or rigging, by means of a swivel in the form of a stirrup, and a thimble.
The foregoing contains the whole description, and nearly in the words of the patentee.
