cylinder-heads fitted thereto, said cylinder-heads having
secured to them inlet and exhaust valve-boxes with valves
therein operated by fulcrumed levers, cams, and skew-gears
from a crank-shaft running in bearings mounted on a bed-
plate, said bedplate carrying columns which in turn support
the cylinder and guides for a crosshead formed at one end of
the piston-rod, said crosshead being connected to the crank
by means of a connecting-rod, the other end of the piston-rod
being extended some distance through said cylinder-head
and working in an oil chamber, and having a hole formed
through its core, said hole joining two diagonal holes formed
in the piston, said piston-rod working through glands and
stuffing-boxes fitted with split conical metal rings and metallic
ribbon-packing in the manner and for the purpose set forth,
as described and illustrated. (2.) In the double-impulse in-
ternal explosive engine covered by claim 1, the piston-rod
stuffing-boxes being fitted with a series of conically shaped
split metallic rings and intervening packing of shredded or

No. 23121.—8th July, 1907.—ANTON RAKY, of Erkelenz,
Rhine, German Empire, Manager (assignee of Wilhelm Schott,
of Erkelenz, Rhine, Germany, Foreman). Improvements in
deep-boring apparatus.

Claims.—(1.) A deep-boring apparatus, having the boring-
beam or swipe connected by means of connecting-links with
a second swipe which is counter-weighted in order to support
the boring swipe, thereby aiding and relieving the springs
carrying the boring-beam and the boring-rod, and avoiding
increase of spring-tension when the weight of the boring-rod
increases. (2.) A deep-boring apparatus, as claimed, in which
the fulcrum of the relieving-swipe is movable for the purpose
of rendering the stroke of the boring-swipe larger or smaller
without the necessity of changing the stroke of the driving
mechanism. (3.) The deep-boring apparatus, constructed
and operating substantially as described and illustrated.
