PROVISIONAL SPECIFICATION
Improvements in Power-tilted Machine Hammers.
CHARLES MARSHALL, of Church Vue, Sandal, Wakefield, in the County
of York, Machinist, do hereby declare the nature of this invention to be as
follows:-
This invention embraces and relates to improvements in power tilted machine
hammers, which is actuated by means of a belt and eccentric arrangement for the
purpose of imparting a reciprocating motion to tappit arrangement. Also, method
of $
of uniformally or differentially controlling the stroke or beater,-by means
treadle lever actuating a rocking or oscillating shaft, carrying levers connected by
means of links, to eccentric or reciprocating rod, in order to produce light or
heavy blows, in the process of welding, or in the manufacture of light forgings.
Fig. is a sectional side elevation. Figs. 2 and 3, are sectional elevations
shewing the method of or means employed in order to facilitate the setting or
adjustment of anvil V, to any required angle.
Fig. 4, is a plan of the machine.
In order to carry out my invention, I employ framework or supports A, carrying
cross shaft B, on which beating lever C oscillates.
Levers D', D, and E are keyed on shaft B.
Shaft Fon which is mounted or fixed eccentric G, driven by belt and pulley H
or similiar motive arrangement, revolves in suitable bearings attached to
frame A.
Tappit J, is retained in the end of reciprocating rod K, by means of pin L.
Links M', and M2 connects red K with levers D' and D. Rod N, connects treadle
lever O, with lever E of rocking shaft B. Springs P1 and P3, are arranged for
the purpose of steadying or poising beating lever Č. A wood shaft 2,-to which
is affixed hammer R, is fitted into socket S, and fastened by means of bolts. The
tappit nose J, and C¹ are faced with steel plates 3, in order that they may be
renewed when necessary.
Whenever the hammer R is required to be stationary, or at rest-spring T
acting under the treadle lever O, forces levers E, D' and D2 backwards, causing
reciprocating rod K carrying tappit J, to fall clear of tappit nose C¹. The
workman may, by depressing treadle lever O with his foot, actuate or otherwise
cause the levers E, D' and D', to move forward reciprocating rod K and tappit J,
in order to strike tappit nose C¹ according to the desired height hammer R is
required to be raised.
Au iron stand or pedestal U is arranged to hold anvil V, swage or any other
ordinary tools-is placed directly under hammer R. The upper part of U may
be formed in two parts as illustrated in Figs. 2 and 3, in order that anvil or
swage V, may be tilted to any required angle. X works on shaft Y and is secured
by means of set screws Z, as iudicated in Figs. 2 and 3.
Dated this 2nd day of March 1894.

CHARLES MARSHALL, of Church Vue, Sandal, near Wakefield, in the County
of York, Machinist 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 :-
This invention embraces and relates to improvements in power tilted machine
hammers, which is actuated by means of a belt and eccentric arrangement-for the
purpose of imparting a reciprocating. motion to tappit arrangement. Also, method
of uniformally or differentially controlling the stroke or beater-by means of a
treadle-lever, actuating a rocking or oscillating shaft-carrying levers connected
by means of links, to eccentric or reciprocating rod, in order to produce light or
heavy blows, in the process of welding, or in the manufacture of light forgings.
Fig. 1 is a side elevation. Fig. 2 illustrates the method of, or means employed,
in order to facilitate the setting or adjustment of anvil V:
Fig. 3 is a sectional illustration of my invention.
Fig. 4 is a plan.
Fig. 5 is a side elevation of anvil V.
In order to carry out my said invention, I employ framework or supports A, as
indicated in Figs. 1 3 and 4, carrying cross shaft B.
Shaft F, on which is mounted or fixed eccentric G, driven by means of belt
and pulley H, or similiar motive arrangement, revolves in suitable bearings I,
attached to frame A.
Tappit J is retained in the end of reciprocating rod K, by means of pin L.
Links M and M² connects rod K with levers D1 and D2. Rod N connects treadle-
lever with lever E of rocking shaft B. Springs P1 and P2 are arranged for the
purpose of steadying or poising of beating lever C.
A wood shaft 2, to which is attached or fixed hammer R, is fitted at the other
end into socket S, and fastened by means of bolts.
Tappit noses J¹ and Care faced with steel plates 3, in order that they may be
renewed when necessary.
Whenever the hammer R is required to be stationary or at rest, spring T, which
is connected at one end to a stud, and at the other end to treadle-lever O for the
purpose of, and as a means of forcing or actuating levers E, D1 and D2 backwards,
thereby causing reciprocating rod K carrying tappit J, to fall back, clear of the
tappit nose (of lever C.
The workman may, by depressing treadle-lever O with his foot, actuate or
otherwise cause the levers E, D' and D² to move forward reciprocating rod K and
tappit Jin order to strike tappit nose of lever C, according to the desired
height, or the weight of blow that hammer R is required to be raised, or
to strike.
An iron stand or frame U₁, which is fixed directly unler hammer R is arranged
to hold or retain anvil V, swage, or any other ordinary tools. The workman or
operator can move, or cause to be moved, by means of slide 2 and weight 7 and
lever 5 arrangement the anvil V longitudially across, in order to bring into
action, and to allow the hammer R to beat on any part of the !ace thereof.
The sleeve 1 is propelled on slide 2, by means of lever 3 keyed on shaft 4
actuating lever 5 to engage with pins or studs 61 and 62. A balance weight 7 may
be placed on lever 5 in order to assist materially the operator to move anvil V to
any part of slide 2.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. Power tilted machine hammers actuated by means of eccentric G, and
reciprocating rod K with tappit J acting in connection with oscilating lever C,
substantially as described for the purpose herein specified.
2. Means employed for the purpose of uniformally, or differentially controlling
the action and stroke of beating lever C, and hammer R, as herein shown,
substantially as described.
3. The method and means employed, for the purpose of moving anvil V, as
herein shown and as illustrated in Figs. 2 and 5.
4. The general construction and combination of parts, substantially as described,
illustrated, arranged and indicated, in Figs. 1, 2, 3, 4, and 5 of the accompanying
drawings.
Dated this 20th day of November 1894.
