PROVISIONAL SPECIFICATION.
New or Improved Manufacture of Dog Spikes and other Spikes,
Holdfasts, Nosekeys, and the like.
We, WILLIAM HORNCY, Nail Manufacturer, and WILLIAM JOHNSON, Iron Merchant,
both of Easington Lane, in the County of Durham, do hereby declare the nature of
this Invention, to be as follows:-
Hitherto dog spikes and other spikes have been manufactured out of rod iron, the
usual mode being first by hand to form the point and then the head or turned up
part.
Pressed nails have been made by cutting from bands of a wedge section and
the heads afterwards formed.
Now according to our invention we make dog spikes and other spikes, nosekeys for
shafting, and the like entirely by machinery all as hereinafter described whereby we
materially cheapen the cost of production and at the same time improve the quality of
the goods.
We roll iron into bands of the section required for the article to be produced, that
is to say, with a rib or head along one edge of the band and that either with a rib
projecting on one side only (for dog spikes and the like having one sided heads) or
with a rib projecting on both sides (for spikes and the like having double sided
heads.) The body of the band may, for dog spikes, be kept parallel for a distance
and then taper off to the point edge. The body of the band may also be rolled with
serrations or grooves lengthwise on one or both sides so that the spikes cut there-
from would have cross serrations as is sometimes required for giving greater holding
power and used for instance for fastening down railway chairs.
From the section bands made as described and reheated as required we cut the
spikes or the like by shears or shearing machines constructed with feeding device for
ensuring accurate work.
In case of spikes nosekeys and the like requiring greater finish we pass them
through finishing dies as they come from the shears and while still hot.

COMPLETE SPECIFICATION.
New or Improved Manufacture of Dog Spikes and other Spikes,
Hold fasts, Nosekeys, and the like.
WILLIAM HORNCY, Nai! Manufacturer, and WILLIAM JOHNSON, Iron Merchant,
both of Easington Lane in the County of Durham 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:—
Hitherto dog spikes and other spikes have been manufactured out of rod iron, the
usual mode being first by hand to form the point and then the head or turned up part.
We are aware that pressed nails have heretofore been made by cutting from bands
of a wedge section and the heads afterwards formed.
Now according to this invention dog spikes and other spikes, holdfasts, nosekeys
for shafting and the like are made entirely by machinery all as hereinafter described,
whereby we materially cheapen the cost of production and at the same time improve
the quality of the goods.
We roll iron or steel of the section required for the article to be produced,
that is to say, with a rib projecting on one side only (for dog spikes and the like
having one-sided heads) as for instance as shewn in Fig. 1, where A represents

page_text: a bar of dog spike section. Or we roll the iron and steel with a rib projecting
on both sides (for spikes and the like having double sided heads.) The body of the
band or bar inay, for dog spikes, be kept parallel for a distance and then taper
off to the point edge, as shewn. A bar of such a section is then cut up into spikes by
means of shears of a suitable form. For this purpose we provide a shearing machine
having a plate B of a form corresponding to one side of the bar, that is to say, con-
forming to the rib A¹ and to the tapered odge A. Fig. 2 is an end view of the
plate B and the top shear C, the latter having a tapered cutting edge as shewn in the
sectional view Fig. 3. The rolled bar A is passed along over the groovel plate B, at
the end of which is fitted a shear blade C made from the best steel and of a section
as shewn in Fig. 3. This shear blade is fitted to an ordinary nail making machine or
by preference in a specially made strong shearing machine worked by eccentric and
cuts off a dog spike at each stroke. The dotted lines in Fig. 1. indicate the way the
bar A is cut up into spikes. A guide or stop rest is provided behind the shear in
order to get all the spikes of exactly the same width. After each stroke of the
shear the bar A is by the workman or automatically fed forward against the guide,
the shear then descends again and cuts off a spike and so on until the bar A is cut
up. In this manner dog spikes, of the form shewn in Fig. 4, are made. The spikes
or other objects may be cut either cold or hot.
The body of the bar or band A may be rolled of various sections to produce spikes
of various forms such for instance as shown with double sided head in Fig. 5. The
body of the bar or band A may also be roiled with surrations or grooves on one or
both sides lengthwise so that the dog spikes would have cross serrations as shewn in
Fig. 6. or the double sided head from Fig 7. as is sometimes required for giving
greater holding power, and used for instance for holding down railway ehairs.
In case of spikes, nosekeys and the like requiring greater finish we pass then
through finishing dies as they come from the shears and while still hot.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the saine is to be performed we declare that what we
claim is :-
1. The manufacture of dog spikes and other spikes, holdfasts, nosekeys, and te
like by rolling iron or steel to the section of the article to be made and then sheating
off pieces of the required for substantially as shewn forth.
2. As improved articles of manufacture dog spikes and other spikes, holdfasts,
nosekeys, and the like made by shearing off from bars of the section of the article to
be made and finished in dies or not.
3. The plate Bas a bed for the sectioned bar which is to be cut up into dog and
other spikes holdfasts, nosekeys, and the like, in combination with a shear sub-
stantially as set forth.
