Improvements in the Manufacture of Railway Beater-picks and
other like Tools.
I FRANK SCOTT 255 St. Philips Road, Sheffield in the County of York Steel
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention has for its object to reduce the labour and thus cheapen the
production of Railway beater picks, ordinary picks and mattocks, and it consists in
casting in steel or iron the socket with the eye, and the whole or a portion of blades
or points in a metallic mould specially prepared for the purpose.
Thus for example, in the manufacture of a beater pick of the usual construction
having a T shaped end to one of the blades, I prepare a metal mould in two halves, the
division being made longitudinally.
"
I prefer to make the mould so that the molten steel may be poured in at one end,
and preferably at the "point" end; the centre of the mould is constructed to the
outside configuration of the head or socket and is prepared to receive a suitably
constructed core to form the " eve or shaft opening. The said core which is
supported and held in position at each end between the sides of the mould, in
recesses made for that purpose I prefer to make of sand or composition in the usual
manner, and protected at the part upon which the molten would fall by a steel plate,
but I do not bind myself to this arrangement.
"At the opposite end of the mould which is to form the T shaped end of the pick,
side recesses are formed in the mould of greater width than the intended arms of
the T, the ends nearest the centre of mould being filled up with sand, loam, or other
compressible material, which will give way under the pressure of contraction as the
metal cools in the mould.
In casting ordinary picks I propose to cast the blades short, and draw them out
to the desired length and point them under a hammer.

Improvements in the Manufacture of Railway Beater-picks and

I, FRANK SCOTT 25.) St. Philips Road Sheffield in the County of York, Steel
Manufacturer 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 :-
-J
This invention has for its object to reduce the labour, and thus cheapen the
production of Railway beater-picks, Miners Picks, and other Picks, Mattock's and the
like, and it consists in the method of casting in steel, the socket and the parts to
form the blades or points, constituting a mould or "mood," in a metallic mould
specially prepared for the purpose.
And in order that my invention may be clearly understood 1 annex a sheet
of drawings representing the metallic mould I prefer to use for ordinary picks.
Fig. 1, represents the outside of the mould.

page_text: In carrying out the invention in producing ordinary picks, I use a mould such
as is illustrated in the Figs. 1, 2, 3, the said mould being made of suitable metal, such
as cast iron.
I make the mould in longitudinally divided halves, for example the line A, B,
Fig. 3, shows the division of the mould described, the face of said division being seen
in Fig. 2.
I prefer to make one end C, of the mould closed, the other, D, being the top end, is
left open to receive the molten steel, but I may if thought desirable arrange for the
molten steel to enter the mould at the bottom end C, instead of at the top.
The interior of the mould is constructed to correspond with the outside
configuration of the pick mould, the blades being made stronger and shorter than
the finished article, so that they can be drawn and lengthened as well as pointed
under the hammer, which operation improves and solidifies the material.
The core to form the opening for the pick-shaft is made of some refractory com-
position; one of its ends fits into and closes the opening at E, the other end fits into
the opposite opening F, each end being held between the two parts of the mould. Or
I may employ an elastic or compressible metallic core that will contract, to avoid
breaking the casting as the metal cools.
The moulds may be used singly or in clusters, for which purpose the mould is
prepared with stop pieces G, to form bearing surfaces for the adjacent moulds when
they are to be cramped together.
In the manufacture of railway beater picks, having a T shaped end to one of the
blades, I make that end of the mould as shown in Fig. 4, having the side recesses H
of greater width than the required T, and I fill the extra space on each side with
refractory or friable material or composition I, so that when the metal forming the
blade J, contracts in cooling, the friable composition crushes and gives way instead of
causing a fracture in the casting.
I propose to cast the eye of the pick at F, longer than is required, and afterwards
to saw or otherwise cut off the excess of metal, so as to obtain a perfectly clean and
sound edge.
The usual process of manufacture being to stamp the steel into the form of the
mould or "
mood" and afterwards to finish them to shape, a mild or soft steel is
generally used, but by my process of casting such "moods," I am enabled to employ a
harder and superior quality of steel, and thus to produce a more durable tool.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
« mood" of
1. In the manufacture of Picks and Mattocks, casting the mould or
the pick or other article, in a metal mould, constructed substantially as hereinbefore
described and illustrated.
2. In the manufacture of beater picks, casting the pick "mood" in a metal mould,
the Tend of the mould being constructed and prepared, substantially as described, and
shown in Fig. 4.
