I AUGUSTO GUATTARI of 91 Shirland Gardens, Paddington in the County of
Middlesex,. Engineer, do hereby declare the nature of the said invention for
"AN IMPROVED MACHINE FOR CARVING, MILLING, DRILLING, CLEANING, AND
OTHER SIMILAR OPERATIONS to be as follows:--
"
This invention relates to an improved universal machine for drilling, milling
cutting shaping or carving and other operations the tool used being an ordinary
drill bit a milling cutting or shaping tool, or a wire or other brush according to the
nature of the operation to be performed and the kind of material operated on.
The invention consists first in mounting the work table or bed upon a ball and
socket universal joint whereby it may be inclined in any direction in order that the
work may be presented to the tool in any desired position the ball and socket being.
provided with means for clamping it so as to retain the table at any inclination at
which it may be placed, and secondly in combining with said ball and socket joint
a compound slide rest whereby the position of the table may be varied in any
direction horizontally and may also be raised and lowered in order to vary the
position of the work relatively to the tool as may be required.
The table is provided with dogs at opposite sides operated by a right and left
handed screw for clamping the work and the ball and socket joint is situated
immediately below the table and is supported upon the compound slide rest of
which the slides work at right angles to one another and are operated by screws,
said slide rest being supported by a bracket arm projecting from the pillar of the
drill and capable of being slid up and down thereon by a rack and pinion or screw
for adjusting the height of the table.
'
The drill spindle is mounted at the upper part of the machine and is driven by
a belt running on speed cones and may be raised or lowered in the ordinary way.
Dated this 4th day of February 1884.

Middlesex, Engineer, do hereby declare the nature of my invention for "AN
IMPROVED MACHINE FOR CARVING, MILLING, DRILLING, CLEANING AND OTHER
SIMILAR OPERATIONS" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—

This Invention relates to an improved universal machine for drilling, milling,
cutting, shaping or carving and other operations, the tool used being an ordinary
drill bit, a milling, cutting, or shaping tool, or a wire or other brush, according to
the nature of the operation to be performed, and the kind of material operated on.
The invention consists first in mounting the work table or bed upon a ball and
socket universal joint, whereby it may be inclined in any direction, in order that
the work may be presented to the tool in any desired position, the ball and socket
being provided with means for clamping it so as to retain the table at any
inclination at which it may be placed, and secondly, in combining with said ball
and socket joint, a compound slide rest, whereby the position of the table may be
varied in any direction horizontally and may also be raised and lowered, in order
to vary the position of the work relatively to the tool, as may be required.
In order that the invention may be more readily understood, I bave illustrated it
in the accompanying drawings, representing side and front elevations of the
machine, and I will proceed to describe it with reference thereto.
The work table a is provided with dogs b at opposite sides operated by a right
and left handed screw c for clamping the work, d, e is the ball and socket universal
joint situated immediately below the table, to the underside of which the ball d is
connected by a stem d¹. The socket is made in two parts united by flanges and
is supported upon the upper slide f of a compound slide-rest, of which the slides f, g
work at right angles to one another, and are respectively operated by screws h i,
said compound slide rest being supported by a bracket arm k projecting from the
pillar of the drill and fitted to slide up and down on ways m thereon, this
adjustment being effected by a rack and pinion or screw gear 1, for adjusting the
height of the table a.
The drill spindle n is mounted at the upper part of the machine, being journaled
on bracket arms o, o¹, and is driven by a belt running on speed cones p, q, of
which is fast on a sleever confined between arms o, o², through which sleeve the
spindle m passes and to which it is connected by screw studs 8 engaging in
longitudinal slots t in the spindle m, to permit of said spindle being raised or
lowered in the ordinary way by means of a lever u pivoted at vand connected to
the spindle m by a swivel w.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
'
1. In a machine for drilling and other similar operations, the combination with
the work table or bed and its support of a ball and socket universal joint for
enabling said table to be inclined in order to present the work in the desired
direction to the tool, substantially as desired.

page_text: 2. In a machine for drilling and other similar operations, the combination with
the work table or bed of a ball and socket universal joint and of a compound slide
rest for supporting the same, the universal joint being interposed between the slide
rest and table, whereby the inclination of the table and also its position both
horizontally and vertically, may be varied relatively to the tool, substantially as
shown and described.
