operators remove the articles of glassware from the conveyor for packing. The heat within the tunnel at and in flproximity to the {)eceiving end thereof is en ciently great to rin structure are removed. From this zone (commonly called the heating zone) rearwardly, the temperature in the tunnel gradually decreases, the temperature gradient being such that strains and stresses of an ap reciable degree, do not reappear in t e g ass, and the articles therefore leave the leer in condition to withstand the hard usage to which they are subjected. Below a predetermined point rapid cooling of the glassware does not detrimentally affect the character and strength of the glassware. Accordingly, artificial cooling is frequently, and in fact generally, employed to bring the temperature of the glassware down to a point at which the operators may readily handle the were for packing.

An object of the present invention is the provision of novel means for cooling the leer tunnel and therewith means by which the effectiveness of the cooling means may be controlled and regulated both as to the zone affected and degree of cooling obtained. To this end the invention comprises the provision of a series of chambers or compartments extending across the leer roof and in fact forming said roof, and the further rovision of means whereby a cooling medium may be introduced into any or all of the chambers or compartments in regulable quantities.

Another object is the provision of novel means for controlling the effectiveness of the cooling medium in any or all of'the chambers the temperature of the ware to a point at which any strains or stresses in the glass part apparent and In thedrawings:

In the illustrated embodiment of the invention, the leer comprises an elongated tun-' nel 10 supported on wheels 11 so that the entire leer may be moved as a unit relative to a ware forming machine (not shown). The tunnel may include sheet metal bottom and side walls 12 and 13 respectively entirely encased in suitable insulating material 14. An endless reticulated conveyor 15 has a ware bearing reach extending through the leer tunnel and supported in spaced relation to through the heating and cooling zones A and B respectively, in the leer. Any suitable heating means (not shown) may be employed to heat the tunnel. 7

According to the present invention the cooling zone includes a roof composed of a series of chambers 19 extending transversely of the leer and at least partially, 11? not completely, encased in insulating material. These chambers (Fig. are

supported directly on the upper ends of the side walls 13.

Each chamber is provide dwith a pair of opposed inlet ports 20 at its ends connected to headers 21 through branch pi headers extending rearwardly a on leer tunnel and connected to a b motor 24. A cooling which is operated by a cs 22, said side the ower 23- medium is forced into the headers 21by the the opposed inletports blower 23 and enters the chambers through 20. Dampers 25 in the branch pipes22 are adjustable to regulably control the volume entering the chambers.

of cooling medium Each pair of dampers are adjusted by means including a shaft 26 extending transversely above the leer tunnel (Fig. 5), said shaft'having beveled gears 27 on its ends,

running in mesh with gears 28 at the upper ends of spindles 29 which carry said dampers pair (Figs. 1 and 5) 25. One shaft 29 of each carries a beveled gear 30 at its lower end just below the corresponding branch pipe 22, times to mesh with a said gear adapted at beveled gear 31 on a control shaft 32. This control shaft 32 extunnel and is journaled bearings 33.

tends lengthwise along one Coil springs side of the leer spaced points in 34 encircling the shaft 32 between said gears 31 and adjacent bearings 3 operate to y gears out of mesh the operator may angular positions of the ieldingly hold said with the gears 30 so that individually adjust the dampers 25. Thus the dampers regulating the inflow of cooling medium to the chambers may be adjusted as required by operating conditions, to obtain varying degrees of cooling. Further, after a predetermined coolin curve has been established, all points 0 this curve may be raised or lowered corresponding degrees,

wise, causing the gears merely by moving the control shaft 32 length- 30 and 31 to mesh with one another and then rotating the control shaft so that the angular positions of the dampers 25 are changed.

Exhaust of the cooling air from each chamber 19 takes place through an outlet port 35 (Fig. 5) arranged of the chamber midway in the up r wall between t e inlet orts 20. Exhaust of the cooling air is reguated by a damper 36 to further control its effectiveness in cooling the leer tunnel. Each damper comprises two plates 37 hinged at their lower ends to a. shaft 38 extending transversely c9 its center.

of the chamber substantially at This shaft (Fig. 6) may be journaled at its opposite ends in bearings 39 at tached to the side walls of the chambers.

These damper plates 37 extend upwardly through the exhaust port 35 and are connected at their upper en ds through links 40 to a lever 41, the latter pivoted to a hinge pin 42 on a bracket 43 risin from the roof of the leer. The outer end 0% this lever 41 is connected through a cable 44 to a counterweight 45 whose weight is sufiicient to substantially balance that of the damper plates. Thus the counterweight holds the damper 36 in any adjustedposition.

In order to substantially balance temperature: conditions transversely of the leer in the cooling zone, the lower walls 46 (Fig.
