Improvements in Pneumatic and other Hammers and Stamps.
I, ERNEST SAMUELSON of Banbury, Oxon, Engineer do hereby declare the nature
of this invention to be as follows:-
My invention relates to improvements in pneumatic and other hammers and
stamps of the class described in the Specification of former Letters Patent granted
to Daniel Longworth on the 14th July 1890, No. 10963, and consists in the
following modification; whilst retaining the general design and principle as therein
set forth in the above Letters Patent, I arrange the moveable actuating air
cylinder, so that it works partially inside the controlling cylinder, and is guide |
therein by means of a trunk, or other extension, sliding in the top cover of the
controlling cylinder, or in that cylinder itself.

COMPLETE SPECIFICATION.
Improvements in Pneumatic and other Hammers and Stamps.
I, ERNEST SAMUELSON of Banbury, Oxon, Engineer do hereby declare the nature
of this invention and in what manner the same is to he performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates to improvements in pneumatic and other hammers and
stamps of the class described in the Specification of former Letters Patent granted
to Daniel Longworth on the 14th of July 1890, No. 10963, and consists in the
following modification: whilst retaining the general design and principle as therein
set forth in the above Letters Patent, I arrange the moveable actuating air
cylinder, so that it works partially inside the controlling cylinder, and is guided
therein by means of a trunk or other extension, sliding in the top cover of the
controlling cylinder, or in that cylinder itsolf; and in order that my invention
may be more readily understood, I annex the following drawings with description
of same.
Fig. 1 shows general front elevation of hammer complete, whilst
Fig. 2 shows the side elevation of same.
Fig. 3 shows a separate enlarged view in section of the controlling cylinder and
actuating cylinder, whilst
Fig. 4 shows plan of same.
Figs. 5 and 6 show an alternative plan for giving motion to the actuating
cylinder.
The general description and working of the hammer is the same as described in
the Complete Specification No. 10963-1890 granted to Daniel Longworth, and the

page_text: same letters refer to the same parts in the different figures, as well as to the
corresponding parts in above mentioned specification.
In my improvement, as shown in the accompanying drawings, I fit the actuating
air cylinder with a long trunk and cause it to work up and down inside, or
through, the cover S³ of the controlling cylinder S, the upper end of which is in
communication with the atmosphere through the openings S, S.
The actuating cylinder is moved up and down by means of the long links h, h,
which are pivotally attached to it, in the present instance, as shown in the drawing,
to a pair of pins P, P, cast on, or fixed to the top cover; motion is given to these
links, and thereby to the top air cylinder, by connecting them to one end of a
rocking lever E which is driven at the other by a crank shaft B through a
connecting rod.
I do not however confine myself to driving the actuating cylinder through the
intervention of these side links and crank etc. as shown, as the top or actuating
cylinder may be driven by means of a crank motion working in a slide block, as
shown in Figs. 5, and 6, or any other well known means may be employed to
give the actuating cylinder its up and down motion, the bottom or controlling
cylinder remaining fixed.
The controlling arrangement of, the bottom cylinder S and the air holes in the
top or actuating cylinder / are substantially as described in Longworth's Specification
No. 10963-1890.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In a pneumatic or other power driven hammer or stamp, an actuating air cylinder
such as working up and down inside, and guided by, the top cylinder cover of a
fixed controlling cylinder such as S, and driven by any well known mechanical means,
such as shown and described in the accompanying figures.
