page_text: LETTERS PATENT to Stephen Massey, of Openshaw, in the County, of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN STEAM AND

PROVISIONAL SPECIFICATION left by the said Stephen Massey at the
Office of the Commissioners of Patents on the 4th September 1879.
STEPHEN MASSEY, of Openshaw, in the County of Lancaster, Engineer.
IMPROVEMENTS IN STEAM AND OTHER POWER HAMMERS."
My Invention relates to a method of constructing the framing or standards of
power hammers.
:
Instead of adopting the ordinary methods I form each standard or member of
the framing of two or more plates of iron or steel placed parallel to each other and
at convenient distances apart, but with blocks or filling pieces placed at intervals
between them, with bolts, studs, rivets, or other such apparatus to secure the whole
together. The framing or portion of framing thus made may consist of plates
extending through the whole length required, or each plate may be lengthened by
other plates rivetted thereto.
Bolts for securing the frame to the cylinder and base plate may be passed
vertically through the blocks which are fixed between the plates at the top and
bottom thereof.
In overhanging hammers with slides the slide piece (of cast iron, steel, or
malleable iron) is bolted or rivetted against the side of one of the plates, but in
hammers of the arch form between the two plates, and sometimes continued upward
with a flange at top upon which the cylinder is fixed.
In arch hammers of large size the plates are sometimes of the channel or double
T section.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Stephen Massey in the Great Seal Patent Office on the 4th March
1880.

"IMPROVEMENTS IN STEAM OR OTHER POWER HAMMERS."
My Invention consists in a method of constructing the framing or standards of
power hammers. Instead of adopting the ordinary methods I form each standard

page_text: or member of the framing of two or more plates of iron or steel placed parallel to
each other, and.at convenient distances apart,, with blocks or filling pieces placed
between them, with bolts, rivets, or other such apparatus to secure them together.
In the accompanying Drawing Fig. 1 represents my Invention as applied to an
over hanging hammer in side elevation, and Fig. 2 is an end view thereof. At
A, B, are two standards, each of which is formed by two plates k, l, of iron or
steel sawed or otherwise cut out to the required configuration, the boundaries
thereof being represented by a, b, c, d. Between the lower ends d of these plates
are placed blocks e secured to the said plates by rivets, and the blocks e are bolted
to the foundation plate g by the bolts h, which is secured to the foundation in any
ordinary manner, and at i is the anvil. Between each pair of plates k, l, are
thimbles and bolts m for securing the two plates together, and also for carrying
blocks m*, each of which is provided with a projecting part n constituting the slide
for the hammer o, and between the upper parts of each pair of the said plates is
secured a block p to which is bolted the base q of the cylinder and valve boxes 8.
It will thus be seen that by my Invention the framing or standards are obtained
by separate but united plates of wrought iron or steel, cach of such plates con-
tinuously extending from the foundation plate to the cylinder, or part connected
therewith; Fig. 3 shews my Invention as applied to an arch haminer. The standards
A, B, are compounded of plates, as above described, with intervening blocks at
bottom to secure them to the base plate, and between their upper ends are com-
pound blocks p, one of which is shewn detached upon an enlarged scale at Fig. 4,
and to these the cylinder casting is secured, such blocks carrying the slides n;
Figs. 5, 6, shew a similar arrangement, the only difference being the form of the
blocks for the slides, and for supporting the cylinder; Fig. 7 shews another form,
in which the intervening blocks p on which the slides are formed and those for
carrying the cylinder are in separate parts; Fig. 8 shews another method of
constructing my improved aming or standards, especially for hammers of large
sizes. In this case each standard is composed of two plates k, l, provided with
outside flanges, as seen at Fig. 9, so that the whole is channel formed, and upon the
faces of such flanges are bolted the filling blocks p on which the slides n are
formed, and the upper ends of which carry the cylinder casting; Figs. 10 and 11
shew a similar arrangement, excepting that the channel formed standards are
formed in two parts transversely united together by flanges at t; Figs. 12 and 13
shew my Invention applied to an over hanging hammer without slides, the cylinder
being secured to the faces of the top filling blocks. In the above description I have
spoken of my improved framing or standards as comprised of two plates for each
member, but it will be evident that three or more plates may in like manner be
united.
Having thus described and ascertained the nature of my said Invention, and the
manner in which the same is to be performed, I desire it to be understood that I
claim as secured to me under the above in part recited Letters Patent, and for the
purpose above set forth, constructing the framing of steam or other power hammers
so that each member is composed of two or more plates of wrought iron or steel,
each one extending in one piece from the bed plate to the cylinder without
intervening joints.
In witness whereof, I, the said Stephen Massey, have hereunto set my hand
and seal, this Third day of March, in the year of our Lord One thousand
