' may also differ as to its `mechanical embodiment
`provided that the action .ofthe'greater part» of
55 the elements be simultaneous, or almost so, with-'-

of the two blast elements are not very far apart.
The two frames supporting‘the wires are like-`

together as soon as the sheet has penetrated in
‘between the two blasts.
A driving shaft'k, with pulley k' and two
crank shafts vI are carried in bearings y and z,
5 respectively, in the main frame i. The shafts l
are drivenfrom the shaft Ic by gear wheels Ic2
from or nearer tothe sheet. This shifting, even
when continuous, combined with the other
movements of the cooling elements, enables the
varying ofthe intensity of the jet of air or other
fluid. They contribute, furthermore, to the rapid 5
formation of the outer compressed layers, when `

betweenl the periods and amplitudes is such that
every point on the framework r describes a con
tinuous line ofmovement forming interlooping `

with the radii of a circle describing the-move
ment of the first frame as indicated clearly in
Figure 7. This complex movement allows the jet
not to strike the sheet at the> same point, but' to`
glass or other materials, `Ywhiclfrmethod consists
in directing jets of cooling medium thereon so
that the iets sweep _the surface of theglass Aalong

glass or other materials, which method consists
in sweeping the surface of the glass with a series
of jets of cooling l»medium along predetermined
paths, each thereof following a continuous line
jets affords a regular and perfect intermixture
of the air intended to be directed against the
sheet, or to be aspirated bythe latter. In the
35 figure there is represented the line created by
each nozzle, but in point of fact, as the `lines of
the neighbouringnozzles interloop at this point,
the interlooping is ystill more lintricate. Evi
