I THOMAS ROWE WESTON 131 St. Thomas Road Finsbury Park London Iron
Merchant do hereby declare the nature of this invention to be as follows :-
The object of this invention is to provide a steel iron or other metal screw for wood
of sufficient strength and character of thread that in addition to its being capable of
being screwed into wood in the ordinary way with a turn screw, the screw may also
be capable of being driven wholly or partially into wood by means of a hammer or
other tool without injuring the thread of the screw or in any way impairing the
efficacy of the screw. For this purpose I make the outside ridge or apex of the thread
of the screw slightly tapering towards the point of the screw and I also make the
thread of the screw stouter or thicker, than usually done, on the end ridge or apex of
the thread, and preferably more so as the thread gradually approaches towards the
point of the screw. I also make the point of the screw fluted inwards longitudinally
in order to allow the screw to enter into and be turned in the wood more easily. I
also chequer or otherwise roughen the head of the screw in order to prevent the
hammer stricking off when the screw is being driven into the wood, and in order
to give an additional holding or locking effect to the screw, 1 make if desired upon
the thread or near the thread of the screw (whether the screw is specially prepared for
driving with a hammer or otherwise) one or more jags undulations, contortions,
grooves or such like.

page_text: I, THOMAS ROWE WESTON, Iron Merchant, of 131 St. Thomas Road, Finsbury
Park, in the County of Middlesex, 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 consists of the contrivance of a screw for wood, constructed (of any
required size and section) in steel, iron or any other metal of sufficient strength with
a portion cut or stamped with a wood screw thread, but the lower portion is intended
to be drawn out to a point to be able to act as a nail, and to be driven into the wood
up to the bottom portion of the thread, cut, stamped or pressed on the metal to form
the screw, by means of a hammer, and then screwed into the wood by means of an
ordinary screw driver, wrench, or by any other tool used for this purpose.
The screw formed according to this invention may be driven wholly or partially into
wood by means of a hammer or any other hitting or pressing tool, without injury to
the thread of the screw or in any way impairing the efficacy of the screw in connection
with the wood it is driven into. I prefer to make the outside ridge or apex of the
thread of the screw slightly tapering towards the point of the screw, the thread being
stouter or thicker than the ordinary cut of a wood screw thread, on the end ridge or
apex of the thread, and preferably more so as the thread gradually approaches towards
the point of the screw, with the screw head square, octagon, round or any other shape
and the top surface of the head chequered or roughened, and slightly raised and
also construct
rounded towards the centre of the top of the head. When desired
the screw with an additional holding or locking effect by placing near or upon the
threads of the screw one or more waves, curves, burrs, or such like.
And in order that my invention may be thoroughly understood I now proceed to
describe the accompanying drawings thereof, reference being had to letters and figures
marked thereon.
Figure 1, represents the elevation of the wood screw with the point or nail portion
(grooved longitudinally) marked B, and the wood screw thread marked D, shank
marked A, and the countersunk head marked C, and the chequered or roughened top
of head marked F. Figure 2, represents the elevation of the wood screw with a longer
and more pointed nail end (more or less grooved longitudinally) marked B, with a lesser
number of threads to form the screw part D, and the square head marked C, with slightly
chamfered edges and rounded on the surface of the top marked F. Figure 3, repre-
sents the elevation of the wood screw with the nail portion marked B, circular in
section and tapering towards the point of screw, with screw thread D, and counter-
sunk head C, and chequered or roughened top of head F. Figure 4 shows the elevation
of a wood screw with two or more threads marked G, waved or undulated in order to
give an additional holding or locking effect to the screw after the screw is driven home
in the wood. Figures 5, 6, 7 and 8, are the different sections of the nail portion B

page_text: shewing the various longitudinal grooves, but these may be varied without departin
from the nature of my invention.
Like letters refer to like parts in each of the figures.
A, the shank or stem of the wood screw.
B, the spiked or nail portion of the wood screw.
C, the curved or cross cut head of the countersunk, square, octagonal or other shaped
head screw. D, the thread of the wood screw. E, the different sections of the point
of the nail portion of the screw. F, the chequered or roughed head of the screw.
G, the waved threads for locking purposes.
I do not particularly bind myself to make the screws or any part of them according
to the accompanying drawings, as it is evident they may vary without departing from
the nature and object of my invention.
Having now fully described the nature and object of my invention and the manner
in which the same is to be performed, I claim as new & novel the following:-
First. The combination of the wood screw thread D, with the shank or stem A,
with pointed or drawn spike or nail B, with the countersunk, round, square, curved,
octagonal or any other shaped head C, substantially herein described and according
to the accompanying drawings.
Secondly. The combination of a nail and screw together which may be driven into
the wood by means of a hammer without breaking or spliting the fibre of the wood
and be drawn out again by means of a screw driver or spanner, substantially herein
described and according to the accompanying drawings.
Thirdly. A nail or screw which has its drawn out spike or nail provided with a
wood screw thread, substantially herein described and according to the accompanying
drawings.
Fourthly. A nail screw or screw nail having the spike or lower end provided
with longitudinal grooves, substantially herein described and according to the
accompanying drawings.
Fifthly. The head of the nail screw to be either chequered, impressed, or otherwise
roughed, substantially herein described and according to the accompanying drawings.
Sixthly. I claim that a screw nail constructed on the principle herein before
mentioned will when driven into the wood, lock, or bind itself into the fibres of the
wood, but at the same time, the screw may be withdrawn by the means of a wrench
or screw driver, substantially herein described and according to the accompanying
drawings.
