GLASS-CUTTI NG APPARATUS.
SPECIFICATION forming part of Letters Patent No. 295,603, dated March 25, 1884.
Application filed July 25, 1883. (N0 model.)
Iofacturers of photographic dry-plates for dividing and subdividing sheets of glass coated with sensitive material, but which may also be used for cutting glass designed for other purposes. Y t
My improved apparatus is fully described in the accompanying specification and drawings, and the novel features thereof specified in the claims annexed to the said specification.
My improved glass cutting apparatus is illustrated in the accompanying drawings, in
which Figure 1 is a plan view. Fig. 2 is a.
section on the line 00 as, Fig. 1. Fig. 3 is an inverted view. Fig. 4 is a transverse section through one of the sliding jaws and its support, on the line y y, Fig. 1. Fig. 5 isalongitudinal section through one of the sliding jaws on an enlarged scale. Fig. 6 is a transversesection through one side of the sliding frame on the line a z, Fig. 1.
In the accompanying drawings, rep resenting my improved glass-cutting apparatus, A is the base or bed of the machine. B B are suitable ribs or feet, which sustain the base a shortdis.
it tance above a table or other support. 0 O is 5 a movable frame, arranged to be adjusted to different positions on the base, to adapt the apparatus todifierent sizes of the sheet-glass.
D D are the sliding jaws, whichcenter the glass previous to andsustain its opposite edges during the cutting operation. E is the ruling bar or guide for the cutting-tool, F the centeringlever, and G G the connections for operating the centering-jaws. The base A may be of wood or metal, and of any suitable dimensions 4 5 adapted to the size of the largest glass sheets which it is designed to cut by the use of my improved apparatus 5 and it may be a part of or attached to a supporting-table in any preferred manner, so as to allow space underneath it for the action of the centering-lever F and the connections G G. The frame 0, which is made of a shape and size corresponding with the base, is arranged to slide thereon, as rep resented by the full and dotted lines in Fig. 1, being secured thereto by suitable ways or gibs, HH. At one side or end of the frame, and preferably next the operator when the device is in use, the frame 0 is provided with a ledge or rib, is, against which theedge of the glass plate I rests during the cutting operation. The ruling bar orguide E is attached to the sliding frame in such manner that it may be readily removed therefrom for the purpose of placing the glass sheets on or for taking them off from the machine, the bar being arranged so that when in place on the frame one of its edges comes accurately at right angles with the rib 7r. i
In the drawings hereto annexe-d I have represented the guideE as simplyplaced across the frame, its position thereonbeing determined by the pins Z Z,- but it may be attached thereto at one end by a hinge-joint. The pins may pass through openings in the guide, or it may be otherwise suitably connected with the frame, so. that it may be easily removed therefrom.
The apparatus may be used with the guide attached rigidly to the frame at one end only, the uncut glass sheets being slid under the free end of the guide; but I'prefe'r to make the guide freely removable, as herein shown? The sliding centering-jaws D D, which support opposite edges of the glass plate, are arranged to slide in suitable guides, at m, at right angles with the rule E and parallel to the ledge k. Into each of the sliding jaws is inserted a stud, 0 0, Figs. 2 and 3, passing through slots in the'bed, and pivoted to the outer ends of the connections G G, the inner ends of which are pivoted to the lever F at equal distances from and onoppositesides of its fulcrum p. A cord, q, runningover a suitable corner pulley, K, Fig. 3, is fastened to the end ofthe lever F and extends downward 9 5 to a suitable foot-treadle, by depressing which the jaws D D are caused to open or recede equally from the rule E. A spring, R, one end of which is fastened to the leverF and the other to the bed of the machine or the table on which it rests, serves to draw the jaws together and to center the glass plate between them. The positions of the lever and connections when the jaws are opened are represented by the dotted lines in Fig.3. A handlever may, if preferred, be employed to open the jaws when a plate is to be placed on the machine; but I prefer to usea foot-treadle, as above described, as thereby the operators hands are both left free to manipulate the plate. The jaws D D may be arranged so as to receive the glass directly, or the supplementary adjustable. jaws s 8 maybe attached to them for the purpose of adapting the device to different sizes of glass, in either case the jaws being provided with suitable lugs, it, which bear against the edges of the glass, and the upper surfaces of the jaws, inside these lugs, being beveled or rounded downward, as represented at n, Figs. 2 and 5,to avoid scratching the sensitive film on the glass plate,which is inserted into the machine with its film side downward, so that the cutting is done on the back or uncoated side of the plate. The supplementary sliding jaws s s are arranged to be adjusted on the jaws D D by means of thumb-screws a a, and plates or washers v 1; being fitted to a dovetail or other suitablyshaped groove in the jaws D D. By the use of a graduated scale thejaws s s are so adjusted in place on the jaws D D that the lugs t t come equidistant on each side of theguiding-edge of the rule E. Allowance should, however, be made for half of the thickness of the head of the diamond tool used in the cutting of the glass, in adjusting the relative positions of the guiding edge of the rule E and of the lugs t t.
' The practical operation of my improved apparatus for cutting glass will be readily understood from the foregoing description. The
position of the sliding frame 0 and the lugs t t on the centering-jaws having been suitably arranged with reference to the size of the plates to be cut, the rule E is removed or swung out of the way, if it be hinged to the frame, and the jaws being opened by the pressure of the operators foot on the treadle, and one edge of the glass plate being applied to the frame 0 against the ledge 70, the opposite end is placed so that its sides rest on the jaws, which are allowed to close together, so as to bring the center of the plate under the guiding-edge of the rule E, which is applied to the frame over the plate, and the operation of cutting is effected by the operator, who
produced in my improved glass-cutting apparatus, the plate being supported during the cutting operation by one of its edges, and near the opposite end at its two sides, the effect of which is that the sensitive film is entirely preserved from injury, and that any splinters or fragments of glass fall on the base, out of the way, where they cannot scratch or otherwise deface the films, and from which they are readily removed from time to time as they accumulate.
Any suitable device may be employed for connecting the centering-jaws, so that they may move equally on each side of and to and from the rule.
The ledge on the bed or sliding frame which supports the edge of the glass sheet should be beveled downward, so as to prevent injury to the sensitive film.
I claim 1. The combination, with the bed A,'provided with a suitable support for one edge of the glass plate, of the centering-jaws D D and the rule E, substantially as and for the purposes set forth.
2. The combination, with the bed A, of the movable frame 0, provided with a ledge or rest to support one edge of the glass plate, the centering-jaws D D, and the rule E, substantially as and for the purposes set forth.
3. The herein-described cutting apparatus for glass plates, having suitable supports, whereby the plates are sustained and centered under a suitable cutting-rule, out of contact with the bed or frame of. the apparatus, substantially as described.
4:. The combination, with the bed A, provided with a suitable support for one edge of the glass plate, of the centering-jaws D D, adjustable supplementary jaws s 8, having lugs 25 t, and the cutting-rule E, substantially as and for the purposes set forth.
