page_text: I, JOHN MILEY, of the Worth Side Works, Keighley, in the County of York,
Machine Tool Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in fast head stocks of lathes, and
has for its object the arrangement, mounting and combining of what is termed
the back gear of the head stock in a manner that, the belt driving the cone on
the head stock spindle may be conducted thereto from either side of the head
stock at any required angle from the horizontal to the vertical; also by the
novel arrangement of back gear, to be enabled to completely protect the same,
and thus reduce the liability of injury to the attendant; and also to more readily
change the speed of the lathe from fast to slow gear, that is from single to double
gear.
In carrying out my improvement, I construct the spindle bearings in the head.
stock as hitherto, and upon the spindle mount the driving cone, one end of
which is in revolving contact with the spindle, and the opposite end keyed to
a socket in a manner that the socket will slide in the cone, and the said socket
free to rotate upon the spindle when required.
The socket is formed with a spur pinion thereon, and the end of the socket
is extended in diameter and cut so as to form one portion of a clutch box which
is made to slide along with the socket on the lathe spindle.
The lathe head stock at this end is formed with a trough to receive what is
commonly termed the back gear and front wheel, the latter is keyed to the
spindle as usual, and in addition, is prepared with the fast portion of the clutch
box which when in gear with sliding portion, the lathe spindle is driven direct by
the cone.
When desired to run the lathe spindle slower through the back gear, the slid-
ing clutch is moved out of gear with the clutch on the front wheel, the before
mentioned pinion on the socket is then in position to receive the wheel of the
back gear, and the back pinion to gear with the front wheel. The socket of the
back gear is mounted upon an eccentric shaft and operated in the usual manner.
By forming the head stock with a trough to receive the gearing in the manner
described, the gearing is more compact, and can be completely covered, thus
reducing the danger of accident to the attendant, and affording facilities for
changing the gear from single to double without the aid of screw and nut as
is now the common practice, and in addition, by arranging and combining the
spur driving gear at the front end of the head stock as described, the whole of
the cone above the base of the head stock is clear, allowing the belt to be con-

Improvements in the Fast Head Stocks of Lathes.
I, JOHN MILEY, of the 'Worth Side Works, Keighley, in the County of York,
Machine Tool Maker, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement: -
“This invention relates to certain improvements in fast head stocks of, lathes, and
has for its object the arrangement, mounting and combining of what. is, iermed
the back gear of the head stock in a manner that, the belt driving the cone on
the head stock spindle may be conducted thereto from either side of the head
stock at any required angle from the horizontal to the vertical; also by the
novel arrangement of back gear, to be enabled to completely protect the same,
and thus reduce the liability of injury to the attendant; and also to more readily
change the speed of the lathe from fast to slow gear, that is from single to double
gear or vice versa.
In describing my invention in detail, reference is made to the accompanying
drawings in which Fig. 1 represents an end view of a fast head stock constructed
in accordance with my invention, showing the spur driving gear protected by
a trough and cover.
Fig. 2 is a side elevation of the fast head stock with the gear cover removed,
and
Fig. 3 a plan of the same, the gear cover being also removed.
In carrying out my improvement I construct the spindle bearings in the head
stock A, as hitherto, and upon the main spindle B, is mounted the driving
cone C, one end of which at C, is in revolving contact with the spindle B, and
the opposite end of the cone, that of larger diameter, is keyed to a socket D,
by a feather key in a manner that the socket D, will slide in the cone C, and
is free to rotate along with the said cone on the spindle B, when required.
The socket D, is formed with a spur pinion E, thereon, and the outer end of
the said socket is extended in diameter and cut so as to form one portion F, of
a clutch box which will slide with the socket D, on the main spindle B, when
operated by the lever G, which engages with the groove D¹, cut in the enlarged
or extended portion of the socket.
The lathe head stock A, at the clutch and back gear end, is formed with a
trough A, to receive the lower portion of the back gear wheel H, and pinion H',
also front wheel K, which is keyed on the main spindle B, as usual, and in addi-
tion the said wheel is prepared with suitable claws or the like L, forming the
fast portion of the clutch, which when in gear with the sliding portion F, the
main spindle B, is driven by the cone C, through the said clutch.
When it is desired to run the main spindle B, of the lathe head slower
through the back gear wheel and pinion H, and H¹, the socket D, and sliding
portion F, of the clutch is moved out of gear with the fast portion L, on front
wheel K, on the operation of the handle G¹, and lever G, engaging with the
groove D¹, the before mentioned pinion E, on socket D, is in position to gear

page_text: with the back gear wheel H, and the pinion H', to gear with the front wheel K,
the back gear wheel and pinion H and H', being mounted upon an eccentric
shaft S, and operated in the usual manner.
By forming the head stock A, with a trough A¹, to receive the gearing in
the manner described, the gearing E, H, H', and K, is more compact, and can
be completely protected by cover M, made to fit over the top of trough A¹, thus
reducing the danger of accident to the attendant, and by the sliding clutch
arrangement affording facilities for changing the gear from single to double or
vice versa without the aid of screw and nut as is now the common practice:
and in addition, by arranging and combining the spur driving gear E, H, H¹,
and K, at the front end of the head stock A, as described, the whole of the
cone C, above the base of said head stock is clear, allowing a driving belt to be
conducted thereto at any angle from the horizontal to the vertical as may be
required according to the relative positions of the lathe and driving shaft.
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:-
1. The fast head stock of a lathe arranged with the main spindle driving gear
at one end of the head stock, substantially in the manner as shown and described
and for the purpose as hereinbefore set forth.
2. The fast head stock of a lathe in which the cone C, is combined with a
sliding socket D, and clutch on front wheel K, arranged substantially in the
manner shown and for the purpose as hereinbefore described.
