With reference to the drawings, the cuttlng
table herein provided i‘ncludes geneÿally a sta
tionary portion or section A and” a revolving
portion or section B. The station‘ary table sec
tion A comprises a fiat horizontal top la sup
4o ported by legs II braced in any desired manner.
The top H) is formed with a. relativelÿ large, sub
‘stantiaily U-shaped opening l2 facing to the
front of the table and into which ?ts 'the ?at
horizontal circular top I3 of the revolving table
45 section B. The top I3 of the revolving table
section B is positioned slightly above the level of
the top It! 01? stationary table section A and this'
arrangement constitutes a very important fea
turc of the invention.
The circular top I3 of the revolving table sec
tion B is carried at the upper end of a vertical
shaft M rotatably mounted in a hollow standard
Ili supported upon a suitable tramework I6. Pro
vision is made for moving the revolving table top
55 I3 back and forth in the U-shaped openin'g I2
In practice, the glass sheet 21 to be ont is laid
upon the top I3 of the revolving table section so'
that the forward edge thereof is substantiaily
?ush with the front edge of the top III et the
stationary table section and the revolving\ top I3 35
can be moved forward or backward in the U
shaped opèning I2 depending upon the size ot ._
glass sheet being out. When the glass
laid upon the revolving top la, it._ ovei‘hangs or
overlies the stationary top I0 but does not con- 43
tact therewith due to the fact that the top III 18
positioned slightly below the level of top I3.
After the sheet has been properly positioned
for cutting, a circular section or any other odd
shape may be cut.therefrom, and this cutting may 45
be accomplished by the use of any suitable cut
ting apparatus.
There is iilustrated ‘in the drawings, by way et
exemple. the cutting of a circular section or dise
from the glass sheet and the cutting means here- 50
in provided for this purpose includes a circular
base 28 providéd with a vertical stud 2Ii upon
which is revoivably mounted a block 30. This
block is formed with a horizontal opening through
which is inserted a horizontal radius bar 3l 39- 65
cured in proper position by a thumb :zcrew 33
and carrying at its outer end a conventional hand
cutter 32. The radius bar 3! can be adjusted
longitudinally within the block 30 depending upon
the size of disc to be eut.
In cuttlng the glass sheet 21, it is ?rst prop
erly positloned upon the revoiving table top l3
as explained above after which the base 23 of
the cutting means 15 placed upon the sheet at
10 approximately the center thereof and the opera

useful in discarding the cullet by permittlng the
operator to raise the loosened cullet at the front
of the table and push it back over the table into
the cullet box.‘ It has been found that with this
type of cutting table, it is possible for an operator'
to cut considerably more glass par unit of time
then on a solld top stationary table.
The cutting table herein provlded is of advan
tage not only in the cutting of dises or circular
sections but likewise in the cutting of large odd 10
shaped glass fox‘ mirrors.

other hand in a circle upon stud 29 to e?‘ect the
sc0ring of the indicated at 34. After the
15 circular cut 34 has been made, the cuttlng appa
ratus ls removed and the operator then makes
a lateral out 35 to the forward edge of the sheet.
The breaking of the sheet to remove the waste
or cullet is then e?ected by breaklng the glass ?rst
along the lateral score line 35 and in then exert

shapes, di?‘erent forms of cutting meana may be

a stationary section provided with a ?at station
upon breaking away from the sheet will be re
ceived and supported upon the stationary table
top la and the operator can then push the waste
glass rearwardly across the top into the cullet
box 26.
Due to the fact that the revolving table top l3
80 is positioned at a slightly higher level then the
stationary table top ICI eliminates the silding of
the glass over the table during the breaking
thereof as is necessary when using a solid top
stationary table and which sliding movement‘has
35 heretofore resulted in many ?ne scratches in the
glass. With the improved type of table herein
provided, the glass sheet is not moved relative
to the table until the cullet has been completely
broken away so that li: is impossible for the sheet
to be scratched. Among the advantages. to be
gained by the use of the statlonary table section
in conjunctîon with the rotatable table section
are that the stationary table section prevents the
weight of the cullet from falling and causing
45 chipping of the glass and, 1’urther, that it is also

invention herewith shown and described is to
be talten as the prei’erred embodïmen't 01' the
same, and that various changes in the shape, size
and arrangement of parts may be resorted to
without departing from the spirit of the inven
tion or the scope of the subJoined claims.
