reissue filed October 27,

To all whom it may concern M Be it known that 1, JOHN er 31.00, a' United States, residing at New Eagle, Washington. county, Pennsylvania, have invented a new and useful Glass-Cuttin Machine, of which the following is a fuli clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification, in wh1ch- Figure 1 is a plan view of a glass cutting my cutting attachment aptable having plied thereto.

ig. 8 is a detail viewshowing one of the gages in side elevation' y invention has relation to glass cuta p ratus, and has been more particu- (iesigned to provide an attachment for esby'means of which glass sheets may be accurately and rapidlv cut into strips of the desired width. invention rovides an attachment of this character which can be readily applied to a glass cutting table; which is simple in its construction and operation, and which provides means whereby a plurality of cuts be simultaneously made.

will be best understood reference to the accompanying drawings in which I have shown a preferred embodiment of the, invention, and which will now be described, it'being premised, however that various changes can be made in the details of constructions, arrangement and combination of the several parts without departingfrom the spirit and scope of my invention as defined in the appended claims.

, In these drawings the numeral 2 designates a glass cutting table which may be of any usual or suitab e character, and which partly in vertical-section elevation of a portion of plan view showing. certain decutter carrying parts. detail view of one of the spring ting larly Specification or Reissued Letters Patent.

may be provided with a plurality of transverse rollers 3 for facilitating movement of the glass sheets thereon.

Secured to the forward end portion of the table is a frame of a cutting attachment, this frame comprising the end plates 4, one at each side of the table, the twoparallel connecting and transverse guide rods 5, and

the rod or bar 6 which also connects theend plates 4 adjacent to the forward guide rod 5. The end plates 4 support the guide rods 5 above the surface ofthe table. 7 designates gage stops which are secured to the rodor bar 6.-

9 designates a frame portion carries an elongated sleeve 10 adapt ed to slide on one of the guide rods 5. This frame is provided with portions 11 in which are mounted bearing pins or screws 12 (best shown in Fig. 6), and whose pointed ends form the bearings for the transverse cutter shafts 13. In the construction shown there are two of these shafts arranged end to end in axial alinement, each shaft having a bearing on one of the end screws or pins and upon one of the center 12*.at the opposite end. Adj ustably clamped on each of the shafts 13 is a forwardly and downwardly extending cutter carrier. In

12 at one end, pins or screws the construction shown, each of these cuttercarriers consists (see Figs. 5 and 6) of the clamping portion 14 carrying the clamping screw 14; the intermediate member 15 secured to the member 14 by a clamping screw 16 seated in a ing member 18. The member 18 has a socket 19 in its rear end portion which rotatably engages a stud 20 carried by the member 15. The member 18 is secured in the proper ad'- justmentby' means of the clamping screws Rotatably mounted in the forward end portion of the "member 18 is atransverse pin or short shaft 22 havin an opening therethrou pin or she tool by means ofthe" By the construction" carryin arm can be of its s aft .13;an'd can beturned on said arm to vary its angular .position.

the depending lug slot 17; and the cutter hold- 30 tion' stud 20'; each tool shaft 22 can be rotated in its bearing; and each tool 23 can be advertically in its seat in the shaft 22. hese adjustments provide for any desired wcurate setting of the tools. 1

Furthermore, it will be noted thatthe members and 18 form a detachable, universally adjustable self-containing unit. .This unit can be laced on a testing ma- 10 chine, similar to -t e regular machine and all neoessar adjustments made, after which it can be p need on the regular machine in a fixedposition like that which'it occupied on the testing machine.

25 designate oil cups whichare mounted on the end portions of the frame 9, and each of which has a bottom delivery pipe 25' carrying a wick 26 placed immediately in advance of the adjacent tool 23 forthe urpose of conveying lubricant tothe survace of the glass immediately in advance 'of the'tool. Rigidly secured to each shaft member I 13 is a projecting. arm 27, which is arranged 5. to, be engaged by a spring pressed pin 28 (best shown in Figs. 4 and 7). Each of these'pins is seated .in asleeve nut 29'liaving a. threaded bearing in the frame 9, the ring 30 being seated between the head por- 'f the pin28 and the lower end of said sleeve nut. These spring 'pins exert the requisite amount of pressure upon the V cutters during their cutting movements.

Rigidly connectedto the inner end por- 86' tion of each shaft 13 is a projecting arm 31. These two arms converge toward each other at their free ends, the latter being provided with the vertically adjustable stop screws 31. 32 is a hand operated lever arm hinged 4 0 or pivoted to the frame 9 at. 33, and which bears against the headed upper ends of the stoykscrews 31' when in the position shown in ig. 3. I

The operation is as follows The sheets to be cut in strips are placed upon the table 2, as indicated in Fig. 3 and are pushed forward] under the cutters, thereby raismg the utter somewhat and putting the.

springs 30 under slighttension. If neces- .50 sary, at the first cut the leading edge of the sheet may be squared up on the table without reference to the stops 7. For sub-. sequent cuts, the leading edge of the sheet is'advanced until it'engages the stop shoulder 8.- The operator grasps the handle of .the lever 32 and pulls the frame 9 (which with its sleeves 10 forms acarriage) across the width of the table, thereby making two cuts simultaneously and severing a complete strip at each operation. The strip is, of

course, fed forwardly between successive cuts In moving the carriage back to its initial position for a new cut, the lever 32 :is depressed. thereby engaging the heads of screws 31 and rocking the. shafts 13 to lift the cutter carriers and cutters free of the surface of the table.- v

The advantages of my invention will be apparent to those skilled in the art, since it provides a simple, convenient and accurate strip cutter of the multiple cut type capable ofbeing applied to existing tables.
