AN IMPROVED MACHINE FOR DRILLING, MILLING, BORING AND OTHER LIKE OR ANALOGOUS OPERATIONS
Year: 1885

page_text: I, RICHARD CRIDLAND MOLLON of 2 Lansdowne Terrace, in the City and County
of Exeter, Mechanical Engineer, do hereby declare the nature of said invention
for "AN IMPROVED MACHINE FOR DRILLING, MILLING, BORING AND OTHER LIKE OR
ANALOGOUS OPERATIONS" to be as follows:-
The improved machine for drilling, boring and other like or analogous operations
which constitutes this invention is constructed and arranged in the manner
following.
The main frame is vertically arranged. Towards the top of the main frame and
bolted or otherwise secured thereto is a secondary frame. This latter frame which
is surmounted by the drill head or bracket in which is supported the vertically
placed spindle of the drilling, boring or other tool, is fitted with a vertical feeding
screw on which is a slide block free to work vertically up and down on the screw.
The revolution of the screw is effected by a worn, worm wheel and bevel gearing
situated towards the upper end of the screw and driven from a pulley or pulleys
connected by a belt or belts with a pulley or pulleys carried on the shaft of the
fly wheel. In connection with the gearing by which the feeding screw is turned
is an eccentric sleeve or equivalent device for putting the gearing into or out
of gear.
The fly wheel is placed towards the bottom of the main frame at the back
thereof. It is driven by counterbalanced treadles or by other means.
The table on which the work is placed is supported on a slide bracket which is
free to slide horizontally along the face of the slide block above referred to as
capable of vertical motion on the feeding screw. The horizontally sliding bracket
may be connected to the block by means of T shaped slots, or in any other
convenient manner.
The table is thus capable of being moved either vertically horizontally or
transversely. It is also free to rotate on its centre. The spindle of the drilling,
boring or other tool has rotary motion only.

page_text: Towards the lower end of the secondary frame aforesaid is secured a bracket in
which is a socket for the reception of the lower end of the boring bar when the
machine is being used for boring.
Above the fly wheel and driven therefrom by a belt is an emery grinding wheel
or other suitable device for grinding or shaping the tools used in the various
operations for which the machine is adapted.
The features of novelty consist in the use of the table on which the work is
carried and which is capable of being moved as aforesaid, the adoption of a non-
traversing spindle, the combination of the various parts and the general arrangement
and construction of the machine.

I, RICHARD CRIDLAND MOLLON, of 2, Lansdowne Terrace, in the city and county
of Exeter, mechanical engineer, 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:-
-
The main frame is vertically arranged, and, towards the top thereof, a secondary
frame is bolted or otherwise secured thereto. This second frame is surmounted by
the drill head or bracket in which is carried the vertically placed spindle of the
drilling, boring, milling or other tools. The secondary frame carries a vertical
feeding screw which passes through a slide block free to work vertically up and ´
down on the screw. The screw is driven by means of a worm, worm wheel and
bevel gearing situated towards the upper end of the screw, and actuated either
from pulleys or by a hand wheel. The driving gear of the screw is capable of
being disengaged by means of an eccentric sleeve or other suitable device.
The fly wheel is situated towards the bottom of the main frame at the back
thereof. It may be driven by means of counterbalanced treadles, or by pulleys
and belting.
The table on which the work is placed is supported on a slide bracket which is
free to slide horizontally along the face of the slide block above referred to as
capable of vertical motion on the feeding screw. The ways on which the bracket
slides may be connected to the block by means of T-shaped slots, or in any other
convenient manner. The table is thus capable of being moved vertically and
horizontally. It is also capable of turning on its centre. Towards the lower end
of the secondary frame aforesaid is secured a bracket in which is a socket for the
reception of the lower end of the boring bar when the machine is being used for
boring. Above the fly-wheel, and driven conveniently therefrom by means of a
belt, is an emery or other grinding wheel for grinding or shaping the tools used in
the various operations to which the machine is adapted.
Referring to the annexed sheet of illustrative drawings, Fig. 1 thereon represents
in side elevation a machine constructed and arranged according to this invention.
Fig. 2 represents a front view of the machine.
Towards the top of the main frame A, there is bolted thereto the secondary
frame B to which, in turn, is secured the drill head or bracket C in which is
supported the vertical spindle E which carries the drilling, boring, milling or other
tools to be used. In the frame B is fitted a screw D passing through the slide
block F arranged to work upward or downwards on the said screw D which is
caused to turn by the bevel wheels G actuated by the worm i and worm wheel i¹-
see Fig. 2-which are capable of being thrown out of gear by an eccentric sleeve
or equivalent device. The worm and worm wheel may be actuated from the
pulleys H carried on the front end of the shaft-h of the flywheel L, and by which
and the pulleys H¹ the spindle E is driven; or they may be driven by hand.
The machine represented in the annexed sheet of drawings is arranged to be
driven through the counterbalanced treadles K and levers k. It may, however, be

page_text: driven otherwise, as, for instance, from shafting to which it may be connected by
belting. The table N on which is placed the work to be operated upon, is supported
on the bracket O which is free to slide horizontally on the face of the block F, to
the ways of which it may be connected by T-shaped slots, or by other means.
It will be thus understood that the table N may be moved vertically and
horizontally.
It is also capable of being turned on its centre. At the lower end of the
secondary frame B is fitted the bracket P into a socket in which fits the lower
end of a boring bar when the machine is being used for boring. At the back of
the main frame A, and over the fly-wheel, is situated a bracket R fitted with a
spindle on the outer end of which is an emery or other kind of grinding wheel S
in which the tools used in the various operations to which the machine is applicable
may be ground or shaped. The grinding wheel may be conveniently driven by
means of a belt passed over the pulley T and the fly wheel L.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:
1st. The combination, in a machine, for drilling, milling, boring and other like
operations, of a vertically arranged feeding screw such as D, and table N capable
of motion vertically, horizontally, and on its own centre, arranged and operated
substantially as herein above described and shown on the annexed sheet of
drawings.
.
2nd. The combination, in a machine for drilling, milling, boring and other like
operations, of a feeding screw such as D, table N and means for actuating the same
and the tool spindle E, substantially as described and shown on the accompanying
sheet of drawings.
3rd. The combination in a machine for drilling, milling, boring and other like
operations, of the parts and features mentioned in the second claim with a grinding
or shaping wheel such as S, carried and actuated substantially as herein before
described and shown on the accompanying sheet of drawings.
