APPARATUS FOR SORTING GLASS PLATES AND PIECES.

Specification of Letters Patent.

' Patented July 9, 1918.

Original application filed May 8, 1916, Serial No. 96,062. Divided and this application filed May 8, 1916, Serial No. 96.061. Renewed December 3, 1917. Serial No. 205,238.

To all whom it may concern:

Be it known that I, JOHN \VATERLoo, a citizen of the United States, residing at Iilouongahela. \Vashington county, Pennsylvania. have invented a new and useful Apparatus for Sorting Glass Plates and Pieces. of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part. of this specification, in which- Figure 1 is a plan view of one form of apparatus embodying my invention, and

Fig. 2 is a side View of the same.

My invention is designed to provide apparatus for sorting glass plates or pieces, such as photographic plates; and more particularly to providea method and apparatus of this character-by which this work may be done in a much more rapid and eflicient manner than has heretofore been possible.

Referring to the accompanying drawing, in which I have shown one form of apparatus for carrying out ,my invention, the numeral 2 designates a portion of a glass cutting table, which may be of any usual or suitable character; or which may be of the special character described and claimed in my co-pending application Serial No. 96,062, filed May 8, 1916.

In connection with this table, and having its receiving end in convenient relation to the delivery end of the cutting table, I provide a moving carrier or conveyer, which preferably consists of two parallel belts 3 in the form of relatively small endless cords or cables. These cables pass around the carrier wheels 4 on the shafts One of these shafts is driven by any suitable means. In the drawing I have shown this shaft as provided with a friction driving wheel 6 rotated by frictional engagement with the friction pinion 7 on the armature shaft of the electric motor 8.

The plates to be sorted are placed separately and successively by the operator onthe receiving end of this carrier or conveyor, which is well lighted from the under side,

either by natural or artificial light. As the plates move along on this carrier, the operator can readily inspect each of them by looking through and across them, and can thus at once detect any defective plates, or can otherwise assort them according to quality or condition.

This method is greatly superior to the usual method, which requires the operator to take each plate or sheet by the hands and hold it to the light for inspection. By my 7 improved method a single operator can handle a much larger amount of product than has heretofore been possible and can assort it much more efliciently.

I do not limit myself to the-use of the particular conveyer or carrier which I have herein shown and described, since any other suitable device may be employed for this purpose. Preferably, however, it is of such a character as to provide only a limited area. of support for the plates, so that practically the entire area of each plate will be open and unobstructed for its inspection.

I claim:

1. Apparatus of the character described,

comprising two separated movable supports supports having a free pen space between them, substantially as described.

3. Apparatus of the character described, comprising two separated movable supports having their inner edges separated. by a distance less than one dimension of the glass plates or sheets which are to be supported,

. being thereby adapted to support said plates or sheets by their edge'portlons only, said supports having a free open space between and'below them, and said space being later ally open for the admission of light, substantially as described. 4 I k 4. The combination with a glass cutting table, of glass inspecting and assorting means, comprising two horizontally sepabetween said conveyers, substantially as de- 1 rated relatively narrow movable conveyers scribed.

having their receiving portions adjacent to In testimonywhereof, Ihave hereunto set the delivery portion of said table, the dismy hand.

tance between said conveyers being less than the dimension of the glass plates or sheets JOHN WATERLOO' to be inspected, and being thereby adapted Witnesses: to support said plzr'es or sheets by their GEO. B. BLEMING,

edge portions only, tnere being a free space H. M. CORWIN.
