3 Claims. 91-45) Our invention relates to apparatus for spraying or coating glassware including bottles, jars and other articles, with alubricating material such as water or other fluid containing a lubricant. The invention is useful for spraying such articles after they have passed through an'annealing leer but before handling or removal from the annealing leer conveyor.

The clean dry surfaces of the glassware as it emerges from the annealing leer are particularly a lubricating material so that the susceptibility to such injuries is greatly reduced.

A further object of the invention is to provide an apparatus by which the coating material may be uniformly applied to the entire surface of the articles under treatment in an economical and efllcient manner.

Other objects of the invention will appear hereinafter.

Referring to the accompanying drawings which illustrate an apparatus constructed in accordance with the principles of our invention:

Fig. 1 is an elevational view of-the apparatus in operative relation to an annealing leer; Fig. 2 is a cross-sectional elevation at the line :22onl'ig.1;-

Fig. 3 isasection at theline Honl 'igj; Fig. 4 is a part sectional plan view of the suction duct: and

rrhe booth 1: which is positioned over the leer conveyor II and extends transversely thereof, in-

cludes end walls I! (Fig. 2) mounted on channel irons II which may form part of the conveyor supporting frame, and side walls I! spaced above the apron l I to leave an open passageway for the 1 glassware. The spray guns II are mounted on a rod 20 carried on straps 2l which are bolted to the end walls .of the booth. The nozzles are positioned directly over the booth and arranged to direct a spray downwardly through the booth into contact with the bottles. The jet ofspray from each nozzle is flared or spread outwardly as indicated by broken lines 22 (Figs.- 2 and 5), to cover an area which is roughly indicated by the lines 23.

This distribution of the spray is such that each over its entire surface.

bottle or article while passing beneath the booth is completely enveloped in the spray and given a substantially uniform, coating of the lubricant In order to maintain a downward draft through the booth and thereby effectively apply the spray to the bottles, a suction apparatus is provided, including the suction fan or pump I4 and the duct 1'! leading therefrom The duct includes a cylindrical section 25 extending from the fan It along the side of the leer, a section 26 extending beneath and transversely of the leer conveyor, directly beneath the booth t2, and an intermediate tapered section 21.

Fig. 5 is a section through the booth at the line .l! on Fig. 2.

The annealing leer III which may be of conventional construction, includes a traveling endless belt or apron conveyor ll of wire mesh con- I struction which provides a foraminous support for the bottles B or other glass articles and by fan H and duct II for causing a downdraft of the spray through the booth, a tank or tanks It containing a supply of the spraying material, and a piping system together with valves, pressure reducing means, and pressure gauges.

The section 28 is provided with partition walls 2: extending lengthwise thereof and dividing it into a suction chamber 29 and channels 30. The chamber 2! is extended into the section 21 (Fig.

' as 4) and is provided with a damper ii for regulating the distribution or proportioning of the flow through the said chamber and the channels ill. The walls 28 are provided with

ports

32 and 33 at intervals therealong. The walls 28 also terminate at a point spaced inwardly from the end wall 34 of the chamber. The openings thus provided at intervals along the suction chamber serve to regulate the .distribution of the gases drawn through the conduit and .facilitate the even distribution of the spray to the surfaces of the bottles throughout the length of thebooth. The side-walls o the booth serve to protect from outside drafts, in its proper and uniform distribution.

to A damper u is provided in the duct for adiustably refl lating and controlling the force of- 1 the downward draft through the booth. The

damper is adjustable by means of a handle a and held in adjusted position by a ribbed holding ll strip 31.

ect the spray downwardly and aid The spraying fluid is supplied from a tank or tanks I6. Two tanks are preferably employed so that one may be in use while the other is being filled thus providing for continuous operation. Air under pressure, for example, 60 lbs., is supplied through a pressure pipe 38 and distributed to the tanks through a branch pipe 39 for maintaining a continuous pressure upon the liquid in the tanks. The pressure pipe 38 also supplies air through a pressure reducing device 40 to a pipe H leading to a manifold or header 42 through which the air is distributed to the spray guns l3. Air under pressure for agitating the liquid in the tanks may be supplied through a pipe 43 and header 44, the ends of the latter extending upwardly through the bottoms of the tanks. The spraying fluid is conducted to the spray guns through a header 45, pipe 46, manifold 41 and pipes 43.

The spray booth as shown is located a short distance beyond the discharge end of the leer tunnel, permitting the bottles to cool to a suitable temperature before the spray is applied. The bottles are taken off the leer conveyor after the spraying operation for the usual inspection and packing.

Modifications may be resorted to within the spirit and scope of our invention.

We claim:

1. Apparatus for applying a lubricant to the surfaces of articles, said apparatus comprising a support for the articles, a booth positioned over the said support and having side walls spaced above the support for the passage of said articles, spray nozzles above said support in position to direct the lubricant downward through the booth and spray it; on said articles, a suction chamber positioned beneath the support and booth, said 2. Apparatus for applying a lubricating fluid to the surfaces of articles, said apparatus comprising a horizontal support for the articles, a booth positioned over said support, spray nozzles above said support in position to direct the lubricating fluid downwardly through the booth and spray it on the articles on the support, a suction chamber positioned beneath the support and booth, said chamber having side walls provided with port openings at'intervals therealong, channels communicating with said openings, means for applying suction to said chamber and said channels, thereby causing and distributing a down draft through the booth and effecting a substantially uniform distribution of the lubricating fluid to the surfaces of the said articles, and a valve inmrposed between said chamber and the suction means and adjustable to adiustably vary the draft through said port openings.

3. Apparatus for applying a lubricating fluid to the surfaces of articles, said apparatus comprising a horizontal support for the articles, a booth positioned over said support, a row of spray nozzies positioned above the support and arranged to direct the lubricating fluid downwardly through the booth and spray it onto a row of articles on said support, a suction chamber positioned beneath the support and booth and extending lengthwise of said row of nozzles, said chamber being open at one end and having side walls provided with port openings at intervals therealong, channels extending alongsaid chamber at opposite sides thereof and open to said chamber through said port openings, a suction fan, a conduit extending from the fan to said channels and said open end of the chamber, said fan being operable to apply suction to said chamber and channels and thereby causing and distributing a down draft through the booth and distributing the spraying material to the surfaces of the said articles, and a valve in said open end of the chamber adjustable to regulate the distribution of the air flow through said. chamber and channels.
