ATENT JOHN A. WOOD, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN CAVILS.
Specification forming part of Letters Patent No.122,692, dated January 9, 1872.
To all-whom it may concern:
Beit known that I, JOHN A. WOOD, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Hollow Metallic Cavil for steamboats and other water-craft; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being' had to the accompanying drawing and to the letters of reference marked thereon.
The nature of my invention consists in making a new article of manufacture, viz., a hollow cast-iron cavil for steamboats and other water-craft, said cavil being so constructed that it may, through the medium of bolts or their equivalent, be attached to the deck or other part of the boat in a secure and perma nent manner.
To enable others skilled in the art to make and use my 'new article of manufacture, I will proceed to describe more fully its construction.
In the accompanying drawing, which forms part of my specifica-tion, Figure l is a side elevation of my improved hollow cast-iron cavil, and represents it secured to a section of the deck of a boat. Fig. 2 is a longitudinal section of the same. Fig. 3 is a transverse section of the same at line y of Figs. l and 2.
The cavil A may be of any form or size desired, but in every case is constructed of castiron or other suitable metal by casting. This is accomplished through the medium of suitable patterns so constructed as to have their own core of green sand, or by means of patterns and dry-sand core. The casting of the cavil and manner or `method of casting I leave to the judgment and skill ofthe molder. The base B of the cavil is provided with projections C, which are tted into cavities made in the part of the boat to which the `cavil is to be attached. These projections, in combination with the bolts D and plates indicated at e, are used for the purpose of holding the cavil in a iiXed and permanent manner to the deck or other part of the boat. The plate should be set into the part to which the cavil is attached, as shown in Figs. 2 and 3 and as indicated in Fig. 1 by dotted lines. By thus embedding the plate e it will prevent the many accidents and injury to boats which so often occur with boats which are provided with cavils secured to their gua-rds in the old and well-known manner. The projecting plates and nuts or bolt-heads, when projecting below the under surface ofthe guards of boats, have always been a source of trouble and cause of many accidents, all of which will be avoided by securing the cavil in the desired place and position in the manner here` in described and as shown in the accompany` ing drawing.
The advantage of my improvement in cavil consists in providing a cheap, strong, and durable article. This is accomplished by constructing it of cast-iron by casting and making it hollow, as shown in the drawing and hereinbefore described. Oavils of cast-iron will cause less friction and wear on the lines which work on or around them. The foregoing advantages, with others, it will be apparent to boat-builders, will not only demonstrate the usefulness, but also its great advantage as a new article of manufacture.
Having thus described my improvement, what I claim as of my invention is The hollow metallic cavil for steamboats and other water-craft, substantially as herein described, and for the purpose set forth.
Witnesses: JOHN A. WOOD.
A. C. JOHNSTON,
JAMES J. JOHNSTON.
