An Improved wood screw.
I, WILLIAM JOHN TAYLOR, of 7. Brunswick Square, Southampton, in the
County of Hampshire, Plumber, do hereby declare the nature of this invention to
be as follows:-
My invention relates to an improved wood screw, which consists of the forging
process of the point, by this said process threads are formed in place of the usual
plain point.
Hitherto the makers have not been able to discover a method of pointing large
wood screws by a forging process they have resorted to the mode of turning them
in the lathe, and in place of the turned point I adopt the process of forging threads
running up the point, thus saving expense and is an advantage to the screw.
This invention is constructed from iron, steel, bronze, copper, or of any other
metallic substance.
Dated this 28th day of February 1893.

COMPLETE SPECIFICATION.
An Improved Wood Screw.
I, WILLIAM JOHN TAYLOR, of 7 Brunswick Square, Southampton, in the
County of Hampshire, Accountant, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to an improved wood screw, which consists of forging the
point into the required shape by means of dies, by this process threads are formed
in place of the usual plain point as illustrated in the accompanying drawing.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, represents an elevation of the screw.
Fig. 2, is a plan of the top of bottom die.
Hitherto the makers have not been able to discover a method of pointing with a
thread large screws made of iron for uniting pieces of wood by forging, they have
resorted to the mode of turning them plain in the lathe. In place of the turned
plain point I adopt the process of forging threads 6 running up the point c by
means of a top and bottom die (or a pair of dies), thus saving expense, and a great
advantage to the screw.
The top die is constructed to correspond with the top of the bottom die d.
The forging of the thread on the point of the screw is performed by means of the
bottom die being fixed in the bed of a stamp and the top die fixed to a steam
hammer, the said hammer working up and down to strike a blow on the screw blank
whilst the aforesaid screw blank is red-hot.
The head a of the screw may be round, square or of any other shape as now in
common use.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a wood-screw, the forging of the threads on the point c, in a stamping-
press, substantially as herein described and according to the accompanying
drawing.
2. In a wood-screw of any shape, the forging of threads formed on the point,
substantially as described.
Dated this 28th day of November 1893.
