HENRY SUTCLIFFE and WRIGHT SUTCLIFFE, both of Halifax, in the County of
York, Sanitary Engineers, Brass Founders, and Finishers. "IMPROVEMENTS IN
MACHINE REST AND TOOL HOLDERS FOR LATHES EMPLOYED FOR FACING,
Boring, Cutting, CHASING, OR TAPPING, AND SHAPING ARTICLES OF METAL,”
This Invention relates to improvements in machine rest and tool holders for
drilling, cutting, shaping, boring, and chasing or tapping taps or cocks for water,
steam, or other use, and for operating on other like articles of metal requiring
accuracy of fitting and finishing.
According to this our Invention we employ a stand resting upon and secured to
the gantry of the lathe, there being screw adjustment for setting the said stand.
The latter carries a sliding head having a series of spindles. One end of each
spindle is so constructed as to receive and hold a drill or other tool, the other end
of the spindle has thereon a spiral or other spring, and there are as many such
spindles as there are drills, cutting, chasing, or other tools required to be used. The
holding head has a lateral sliding or a rotary motion so as to bring the required
tool into position for work, and a catch and stop appliance ensures the true relative
position of the tool to the tap or other article to bo operated upon.
The action is as follows:-The tap or other article to be operated upon is secured
in a chuck of the fast or running head of the lathe. An arm of the sliding head
above referred to serves as an ordinary rest for use of a skimming or facing tool
The spindle of the loose head of the lathe is now employed for forcing forward
No. 1 spindle in the sliding head so as to advance and apply the drill or tool held
thereby, after which the reverse motion of lathe spindle will permit the spiral
spring to return the tool or drill holding spindle, whereon the catch and stop are
released, and the sliding or rotating head is moved until the next tool is in position
for work, and the catch and stop are again locked, and so on to the end, the
necessary tools being applied without removal and the work greatly expedited and
simplified, and also ensure more accurate fitting and finishing.
The spindles carrying the tools or drills are prevented from rotating by means of
keys fitted thereto.

MACHINE REST AND TOOL HOLDERS FOR LATHES EMPLOYED FOR FACING,
BORING, CUTTING, CHASING, OR TAPPING AND SHAPING ARTICLES OF METAL."
This Invention relates to improvements in machine rest and tool holders for
drilling, cutting, shaping, boring, and chasing taps or cocks for water, steam, or
other use, and for operating on other like articles of metal which require accuracy
of fitting and finishing.
According to this our Invention we employ a stand resting upon and secured to
the gantry of the lathe, there being screw adjustments for setting the said stand.
The latter carries a sliding head having a series of spindles. One end of each spindle
is so constructed as to receive and hold a drill or other tool. The other end of the
spindle has thereon a spiral or other spring, and there are as many such spindles as
there are drills, cutting, chasing or other tools required to be used. The holding
head has a lateral sliding or a rotary motion so as to bring the required tool into
position for work, and a catch and stop appliance insures the true relative position of
the tool to the tap or other article to be operated upon.
The action is as follows:-The tap or other article to be operated upon is secured
in a chuck of the fast or running head of the lathe. An arm of the sliding head
abovo referred to serves as an ordinary rest for use of a skimming or facing tool.
The spindle of the loose head of the lathe is now employed for forcing forward
Number 1 spindle in the sliding head so as to advance and apply the drill or tool
held thereby, after which the reverse motion of lathe spindle will permit the spiral
spring to return the tool or drill holding spindle, whereon the catch and stop are
released, and the sliding or rotating head is moved until the next tool is in position
for work, and the catch and stop are again locked, and so on to the end, the neces-
sary tools being applied without removal, and the work greatly expedited and
simplified, and also ensuring more accurate fitting and finishing.
The spindles carrying the tools or drills are prevented from rotating by means of
keys fitted thereto.
Such being the nature and object of this our said Invention, we will now
proceed to describe in detail the same, and have illustrated the same by Drawings
annexed, of which Fig. 1 is a front elevation, Fig. 2 a side clevation, Fig. 3 a plan,
Fig. 4 a general view of apparatus and the lathe employed in connection therewith,
as hereinafter described; Figs. 5, 6, 7, and 8, are details drawn about full size;
Figs. 9 and 10 shew rotary holders.
At 1 is a bed plate carrying the stand 2 and V slide 3, on which is the sliding
rest 4; at 5 is an ordinary tool rest; 6, 7, 8, 9, are spindles for carrying drills,
cutting or facing tool taps, or other tools required in facing, boring, chasing, or
screwing, and otherwise operating on the tap or cock under operation; the spindles
are carried in supports 10 and 11; in 10 is a key bed for key 10% for preventing
rotation of spindle and tool, the tools being received in the socketted ends 12,
which, as shewn, are provided with holding screws 13; the other ends of the spindles
have spiral springs thereon, 14; at 15 is a handle for withdrawing a holding
piece 16 from a notch 17 formed in the edge of the plates 3 and 4; it will be
understood that there is a like notch 17 for each spindle 6, 7, 8, 9, and that the
number of such spindle tool holders may be increased where greater variety of
tools are necessary.
The use and action of the apparatus is as follows:-The rest is placed upon a
lathe gauntry 16 (see Fig. 4) and by means of the levelling screws 17 17ª set or

page_text: levelled truly on the ordinary bed 18; the bolts 19 and plates 20 secure the whole
firmly in position; the tap or cock 21 is secured in its "chuck" or holding appliances
as ordinary, a hand tool being used on the rest 5 for removing any roughness, or
otherwise preparing the tap to be operated upon, as follows. The operative or
attendant will now by means of the handle 22 push and slide the part 4 until the
catch 16 enters a notch 17; this will bring the tool in the spindle 6 exactly central
to the tap 21, whereon the wheel 22 of the lathe will be turned, the spindle 24
forcing forward the spindle 6 and also the tool held therein so as to operate upon
and cut, bore, or screw the tap 21; the wheel 22 will now be reversed, and the
spiral spring 14 will push and draw back the spindle 6 and tool therein; the
handle 15 will now be turned and the worm 26 will cause the box 27 to press
against the screw 28 attached to the spindle 29, so pulling the catch piece 16 out
of its notch 17. The handle 22 will then be used for forcing the slide piece 4
along the surface of part 3 until the catch piece 16 comes opposite another
notch 17 (cut in edge of 18) opposite the spindle and tool 7, whereon the spiral
spring 30 contained in the box 31 of the boss 32 will, by pressing on the part 33,
force the holding piece 16 into notch 17, and so hold all in true position for the
advance of the spindle 24 of the lathe, as before described. 34 is a light sheet
metal cover for keeping spindles and bearings free from dust and metal turning
borings or cuttings. In the rotating holder is a disc 35 carrying tools 6, 7, 8, 9, a
holding catch 15, as described; the disc 35 rotates in frame or holder 36, and has
a movable cap 37, the tools being in all respects the like to those above described,
and operated by spindle of ordinary lathe. 15*, handle for turning disc 35 and
tools 6, 7, 8, 9.
Having thus fully described the nature and particulars of this our said
Invention, together with the manner in which the same is to be performed or
carried into practical effect, we would have it understood that what we claim as
our Invention is,-
Firstly. The use in combination of the V slide 3, slide rest 4, and spindle drill
and tool holders (such as 6, 7, 8, 9,) as herein described, and substantially as
illustrated by Drawings.
Secondly. The use in combination with spindle tool holders (such as 6, 7, 8, 9,)
of the spiral or other returning spring, herein described and illustrated, and
Thirdly. The application to and use in combination with the improved appliance
herein described of the adjusting screws 17*, as described and illustrated.
In witness whereof, I, the said Henry Sutcliffe, for and on behalf of myself
and the said Wright Sutcliffe, have bereunto set my hand and seal, this
Twenty ninth day of July, in the year of our Lord One thousand eight
hundred and eighty one.
Signed, sealed, and delivered by
the said Henry Sutcliffe in the
