Improvements relating to Supporting Tables for Machine Tools.
and the like.
We, PAUL RICHARD SCHUBERT, of 18, Uhlichstrasse, Chemnitz, Germany,
Manufacturer, and ANDREAS LUDWIG STELZENMULLER, of 8, Zollnerstr, Chemnitz,
Germany, Manufacturer, do hereby declare the nature of our said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
-
The object of the present invention is to provide a work holding table or support
for drilling, shaping and cutting machines which is adjustable in five ways and
the invention consists of the details of construction herein after set forth and
particularly described in the claims.
And in order to render the present specification more easily intelligible refer-
ence is had to the accompanying drawings in which similar letters of reference
denote similar parts throughout the several views.
Fig. 1 is a side elevation.
Fig. 2 a plan.
Fig. 3 an end elevation and
Fig. 4 a vertical central section partly in elevation of one form of embodying
the invention
An adjustable clamping sleeve a is adapted to be vertically adjusted on the
column and to this clamping sleeve is attached a horizontal bar b by any
suitable means such as a flange and studs c, c, or the like.
This bar is hollow and provided with a slot along its upper side through which
a stud f Fig. 4 projects upwardly. This stud is screwed into a nut h adjustable
on a horizontal screw spindle & mounted in suitable bearings in the hollow bar b.
The said screw spindle is provided with a handwheel by means of which the nut
and with the same the stud f may be horizontally adjusted on the spindle.
A collar d fits conveniently around the bar b and has an upper horizontal disc
formed thereon, on which fits a lower disc of a rotary table e said table being
centred on the stud f and adjustable thereon in any desired position by means
of a clamping screw g with handle bar, which screw fits or engages with its end
in an annular recess in the said stud f.
The screw spindle k may be turned by means of the hand wheel i.
In order to adjust the table or support e to any desired position, several series
of holes are provided around its periphery as shown at Figure 4 and an arm is
mounted on the collar d extending outwardly and being turned upwardly so as
to support in its upward end a spring bolt n, said bolt n being carried by a
sleeve m which is vertically adjustable in the end of said arm 7, any suitable means
being employed to adjust the said sleeve vertically.
Thus for instance notches may be made in the arm into which the pin of the
moveable part of the detent bolt m, n engages.
The bolt n, is horizontally moveable within the sleeve and is normally held
in engagement with one or other of the holes in the table disc by means of a
An adjustable clamping sleeve a is adapted to be vertically adjusted on the

suitable means such as a flange and studs c, c, or the like.
This bar is hollow and provided with a slot along its upper side through which
a stud f Fig. 4 projects upwardly. This stud is screwed into a nut h adjustable
on a horizontal screw spindle k mounted in suitable bearings in the hollow bar b.
The said screw spindle is provided with a handwheel by means of which the nut
and with the same the stud f may be horizontally adjusted on the spindle.
A collar d fits conveniently around the bar b and has an upper horizontal disc
formed thereon, on which fits a lower disc of a rotary table e said table being
centred on the stud f and adjustable thereon in any desired position by means
of a clamping screw g with handle bar, which screw fits or engages with its end
in an annular recess in the said stud f.
The screw spindle k may be turned by means of the hand wheel i.
is
In order to adjust the table or support e to any desired position, several series
of holes are provided around its periphery as shown at Figure 4 and an arm
mounted on the collar d extending outwardly and being turned upwardly so as
to support in its upward end a spring bolt n, said bolt n being carried by a
sleeve m which is vertically adjustable in the end of said arm 7, any suitable means
being employed to adjust the said sleeve vertically.
Thus for instance notches may be made in the arm into which the pin of the
moveable part of the detent bolt m, n engages.
The bolt n, is horizontally moveable within the sleeve and is normally held
in engagement with one or other of the holes in the table disc by means of a

page_text: spiral spring, not shown in the drawing, but arranged in the ordinary well known
manner.
When the head o of the detent bolt is drawn back by hand the forward end
of the same will be disengaged from the orifices of the disc, and on releasing
the bolt the same will be actuated forward by means of its spring and engage the
hole opposite its advancing end.
A similar detent arrangement is formed on the hollow bar b, as clearly shown
at Figures 1 and 2. The same arrangement may also be applied in connection with
the clamping sleeve a if desired.
The rows of holes in the edge of the disc are arranged so that the upper row
are closest together the next row below having holes somewhat wider apart and
se on, the holes of the lowest row being furthest apart.
From the above description it will be seen that the table or support may be
adjusted in five ways. vertically on the column a¹, 2 horizontally along the
hollow bar b, 3 partly around the said bar 6 4 on its own central pivot and 5
around the columm a¹.
The bar b is revolubly mounted in the clamp a said bar having a flange a² over
which washers of the studs c grip.
By loosening the said studs, the bar may be turned and then tightened in any
desired position.
A pointer and scale may be provided on the parts a, and a from which the
degree of adjustment may be read off.
Having now particularly described and ascertained the nature of our said
invention and the manner in which it is to be performed, we declare that what
we claim is :-
(1) The combination of a vertical column a clamping sleeve adjustable thereon,
a horizontal bar rotatably adjustable on said sleeve, a disc supporting collar
longitudinally adjustable on said horizontal bar and a disc or table revolubly
adjustable on said collar in the manner and for the purpose substantially as
described.
+
(2) The combination of a vertical column, a clamping sleeve adjustable thereon,
a hollow bar rotatably mounted and means for adjusting the same on said clamp,
a slot along the hollow bar, a screw spindle revolubly mounted within the same
and means for rotating the same, a nut to travel on said spindle having upwardly
extending stud, a table revolubly mounted on said stud and means for clamping
the same in position thereon, and means for adjusting the said table consisting
of a arm on the said collar having a horizontal spring pressed bolt at its end
and a series of holes arranged as specified into one of which said bolt may engage
and means for adjusting said bolt vertically in the end of the arm substantially
as described.
