PLATE-GLASS WASHING AND CLEANING APPARATUS. 4

Application filed April 17, 1922. Serial No. 553 ,488.

To all whom it may concern:

5 State of Ohio. have made an Invention Appertaining to a Plate-Glass Washing and Cleaning Apparatus; and I dohereby leclare the following to be a full, clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon. which form apart of this specification. i

This invention relates to the manufacture of plate glass and particularly to an apparatus for cleaning the glass after apolishing or grinding operation.

In the grinding or polishing of plate glass it is customary to secure-the glass toa table by the application of a cementitious material to the under surface of the sheets. or the surface thereof next to the table. and when the glass is removed fro-m the table a large part of this material adheres thereto. To remove such material an acid is usually applied to loosen the same and the glass surface is then washed free of the material.

The object of the invention is the provision of a simple apparatus for handling the glass sheets during thecleaning operation and adapted to wash and dry the same -in a rapid and efficient manner.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms. a preferred embodiment thereof is illustrated in the accompaning drawings, in which,-

Fig. 1 is a front elevation of an apparatus embodying the invention with the opposite end portions thereof broken away. Figs. 2 and'3 are vertical cross sections thereof on the lines 22 and 33, respectively, in Fig. 4. Fig. 4 is a fragmentary rear elevation of a part of the apparatus, and Fig. 5 is a fragmentary sectional plan View of a portion thereof together with the driving means for the operating part-s.

Referring to the drawings, 1 designates a, skeleton form of frame, which is disposed in slightly inclined upright position and comprises a longitudinally extending base or sill member 2. a plurality of spaced upright members. and a plurality of spaced horizontal members 4 connecting the uprights 3. In the present instance two of the frames 1 are employed in longitudinally aligned relation and slightly spaced apart at their adjacent ends. the frames being mounted in any suit-able manner in slightly inclined upright position. 2 of the frames are provided at their front sides with a plurality of spaced glass plate supporting rolls 5, which are fixed to the The sill strips shafts 6 that project through the respective sill strips and are mounted at their rear ends in supporting bearings 7. The rolls are fixed to the shafts for rotation therewith and each shaft or any desired number of the shafts has a sprocket-wheel 8 thereon at the rear of the frame and. in engagement with a sprocket-chain 9, which extends the entire length of the apparatus in driving engagement with all of the sprocket wheels.

8 thereof. One ofthe shafts 6 has a rear ward extension 10 in driven connection. through a set of gears 11, with a drive shaft 12 disposed at the rear of the apparatus and journaled in bearings 13, and this shaft, in the present instance, is in belt and pulley connection 14: with, a motor 15, or other suitable driving source.

Successive plates of glass 16 are intended to rest at their lower edges on the rolls 5 and to be moved by rotation of such rolls from one end to the other of the apparatus,

the plates taking substantially the incline of the frames and resting freely at their rear sides against guide members 17 projecting from the horizontal frame strips 4 at a predetermined point in a movement of the plates along the frames 1.

A post or upright 18 rises from the foundation 19 in advance of the frames 1, v

and in the present instance, adjacent to their inner ends and carries a.- plurality of brackets 20 in which shafts 21 are ournaled. Each shaft 21 carries a. rotary brush 21 at its inner end in position for the brush. to have scrubbing engagement with the front surface of a sheet 16 as it passes along the frames 1. instance, are three in number and arranged in vertically spaced staggered relation. The

The brushes 22 in the present several shafts 21 have chain and sp-rocket wheel connections 23 to cause them to rotate in unison, and one of the shafts has chain and sprocket wheel connection 24 with the forwardly extended end of one of the shafts 6. It. is thus evident that thebrushes are driven by the same driving means as the rolls '5.

Water or other cleaning liquid is discharged against the front surface of the glass plate 16 above the brushes 22 from a nozzle 25, which is in communication with a suitable source of supply through a pipe 26. The foundation 19 is provided with a drainage passage 27 below the" brushes or point of application of water to the glass plates.

The glass plates 16, after passing beyond the scrubbing members 22 are engaged at the front sides thereof and also preferably at the rear sides by sets of wiper strips 28 carried by screws 29 for adjustment inward and outward with respect to the plates. The screws of the front set of wiper strips thread through a front standard 30, and those for the. rear set of wipers extend through an upright member 31 of the frame. The wipers 28 of each set preferably lap each other at their ends so that the entire surface of a glass plate as it passes along the frame is wiped by the wiper strips.

It is intended to apply an acid to the cemented surfaces of the glass plates before the plates reach the scrubbing members 22, and it is preferable to havea pool or basin 32 provided in the foundation 19 be low the point of application of the acid to the sheets to catch the acid flowing down from the sheets, thereby enabling such acid to be used over. and over. The abid may be applied to the sheets by a brush or in any.

other suitable manner, as well understood in the art."

In the use of my apparatus, glass sheets to be cleaned are successively-placed on the rolls 5 at-the left end of the apparatus and fed slowly forward to the right end of the apparatus by the rotation of the rolls.-

When a sheet is over the acid bath 32 the acid is applied to the front surface thereof scrubbing action'ofthe brushes 22 and the thereon. The rear set of wipers is intended merely to wlpe the rear sides of the sheets of water or other li uid which may have been accidentally applied thereto.

I wish it understood that my invention is not limited to any specific construction, arrang'ement or form of the parts, as it is capable of embodiment in numerous forms without departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,-
