Description

UNITE srarns @FICE LAUNCHING FLAT-BOATS.

Speccaton of Letters Patent No. 26,168, dated November 22, 1859.

To all whom 'it may concern:

Be it known that we, JOHN DAVIS and EBENEZER DAVIS, of Matildaville, in the county of Clarion and State of Pennsylvania, have invented a new and useful ImproVement in the Mode of Launching Flat- Boats; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, forming a part of this speciication, in which- Figure l is a top View of the staging with the boat on it. Fig. 2 is vertical section on line m, showing the boat in position to be lowered. Fig. 3 is a view showing the position of the boat during the different stages of launching.

Similar characters of reference in the several figures denote the same part.

The nature of the invention consists in constructing a fixed staging on which the boat is built, with its top beams arranged in pairs, and between them are hinged beams, projecting the side of the staging, having shoulders on the projecting ends, and on the other end pulleys, also ropes attached the shoulder ends, and passing across lthe boat into the pulleys on the other end of beams, so as to allow the gradual descent of boat from the staging in launching it, as will be set forth.

In the drawing S is the staging, B, B, the top beam, c, the hinged beams between them,

having on their projecting end the shoulders 35 a, and at the other ends the pulleys p.

D, is the boat, and el the rope going across the boat from shoulders a, to the pulleys 29. lVhen the boat is ready to launch, it is pushed to the end of the projecting beams 40 c, against the shoulders a. These beams being hinged between the top beams B, can be easily turned in a vertical position, the boat being held in position against the shoulders a, and by ropes d, and after the 45 purpose herein set forth, when used in con- 55 nection with the permanent staging S.

In testimony whereof we have hereunto signed our names before two subscribing witnesses.

JOHN DAVIS. EBENEZER DAVIS.

Vitnesses WILLIAM BosTAPH, HENRY FULMER.
