(Cl. 3 -r-3 1 2 Claims. My present invention relatesgenerally to appliances employed in cutting sheets of material, and more specifically to an improved two-man glass-cutting board or table, or duplicate table having double working ends for use by two men or operators in cutting sheets of hard glass.
The primaryobl'ect of the invention is the provision of a manually operated appliance by means oi which lots, or multiple sheets orglass may be quickly and successively out to the same sizes, and with precision and accuracy.
In carrying out my invention I utilize a mini! mum number of parts that may with facility be manufactured at low cost or production, the parts may with convenience be assembled, and the equipment in the form of a supporting table, or board, maybe made of various sizes, and adjusted for different shapes andsiaes. The inven tion consists in certain. novel features of construction and combinations and arrangements of parts as will hereinafter be described and more specifically set forth in the appended claims.
In the accompanying drawings I have illustrated one complete example of a physical embodlment of. my invention in a, duplex machinev or appliance, in which the parts are combined and arranged in accord with a'mode I have devised for the practical application of the principles of my invention. It will however be understood that changes and alterations are contemplated and may be made in these exemplifying drawings, within the scope of my claims, without departing from the principles of my invention;
Figure l is a perspective viewshowing a duplex appliance or glass cutting device in which the principles of my invention are embodied.
Figure 2 is a view in side elevation, as seen from the left in Fig. 1.
Figure 3 is a view in elevation at one of the duplicate working ends of the appliance.
Figure 4 is an enlarged longitudinal vertical sectional view at line ld of Fig. 3.
Figure 5 is an enlarged fragmentary View in elevation showing the supporting tracks for the cutter.
In Fig. 4 the use of the duplex appliance is illustrated where the sheetof glass S haspeen cut at one Workin end 015 the applia n t sheet of glass G is in position for the cutting operation; both sheets being supported upon a rectangular table or board I that is preferably fashioned of wood to the desired size and shape.
The inner ends of both of the glass sheets G and S are backed up against an adjustable workguide of general L-shape, or double T-shape, consisting of a transversely arranged block 2 and two right-angle heads or blocks 3 and 4, which form guides forv the oppositely arranged sheets G and S, as they are being out. These transverse and longitudinal blocks are rigidly held together in their precise right-angle or perpendicular positions bymeans of a complementary holder, of metal that includes the transverse bar 5 resting on the block 2 and the two longitudinal angle iron plates 6 and 1 integral with the center bar.
The metal holder maintains the blocks in rigid relation on the base board I, and by means of pairs of vertically extending bolts 8 which are adjustably mounted in the base board, as will be later described, and extending up through holes in the blocks and wing nuts 9, the work guide and holder are fixed in adjusted position on the baseboard.
For duplicate or duplex work guide and the double worklholder are centrally mounted on the board I, in order that the two sheets, at opposite ends of the base board, may be cut to the same size, as indicated in Fig. 4.
A glass cutting device of the rolling Wheel type is mounted transversely of the base board at each end thereof and these devices are adjustable over the upper face of the base board for cutting different lengths or glass sheets. Each cutting device includes a straight edge Ill having a liner ll of wood or other suitable material for con-.
tact with the glass sheet, and the straight edge is provided with a handle [2 for use in manipulating the straight edge, as it is depressed to cutting position, as indicated in Fig. 4, and resilient means are provided for elevating or retracting the straight edge.
The circular cutter or rolling cutting Wheel for each straight edge is designated as 83', and it is journaled in a carriage it that is adapted to travel longitudinally of the straight edge. A cutter handle I5 is grasped in the hand for depressing the Wheel on the upper face of the glass sheet, and this handle passes down through a. slot Id of the carriage or carrier, a retainer plate for the wheel being shown at IT. The straight edge is depressed by one hand grasping the handle 12 while the other hand manipulates the travelling carrier and wheel for cutting the lass sheet.
For adjusting and limiting the length of the cut a slotted gage plate [8 is mounted on the outer face of the straight edge or ruler by means of a pair of bolts [9 and wing nuts 26, and the gage plate may be clamped in adjusted position to limit the travel of the carrier and its cutting wheel.
For cutting diiferent lengths of sheets, each of the straight edge devices is adjustable longitudinally of the base board, toward, and away from the central I-shaped work holder, and means are provided for retaining the adjusted straight edges in position. To accomplish this purpose each straight edge is equipped with a pair of upright bolts 2|, 21, which pass downwardly through holes near the respective ends of the straight edge, and the lower ends of the bolts are each rigidly attached to a slide shoe 22. As best seen in Fig. 5 the bolt passes down through a hole in the shoe, and a nut 23 is threaded on the projecting end of the bolt, which nut is welded to the shoe to provide a substantial support for the upright bolt. A compressible spring 24 is coiled about the bolt and interposed between the straight edge and the shoe, and the pair of bolts and springs provide a resilient support for each straight edge. The sliding shoe is fashioned with an outwardlyextending and overhanging flange 25, and a flanged clip 26 or sliding guide is fastened by screw 27 to the shoe.
To provide an outside track at each side of the base board on which the straight edge may be adjusted an angle plate 28 is attached to the underside of the lateral edge of the board, and these flanged plates 28 are spaced laterally of the edges of the board to provide a groove through which the shoes travel for adjustment and to permit the straight edge to be depressed against the upper face of the glass sheet.
On the exterior face of the flange of the plate 28 an angle iron rail 29 is secured, as by welding, and the guiding clips 26 are slidable on these outside rails of the base board.
To aid in holding down the straight edges at the opposite ends of the baseboard, an angle iron strip 30 is rigidly mounted upon each lateral edge of the board, and the upper face-of the board is grooved or channeled so that the plate is flush with the upper face of the board, and the flange of the plate 36 co-acts with an upturned flange 3| of the slide shoe.
In addition to the plate 30, another plate, as 32 is inset in the grooved edge at each side of the board, and these two plates 30, 32 are spaced apart to form a slotted inside track, one at each side of the board, for a pair of oppositely arranged presser blocks 33, 33, preferably of wood that hold down the sheet of glass while it is being cut.
The hold-down blocks, like the double work guide 2, 3, 4, are adjustable longitudinally of the board or table, and for this purpose the board is grooved or channeled at 34, 34, near the opposite lateral edges of the board and the clamp bolts 8 of the double work guide are adapted to move in the slots when adjusting the double work guide to a desired size for the sheet of glass.
The hold-down blocks, which clamp down on the top face of the sheet of glass, are each provided with a clamp bolt 35 having a head 36 retained in the groove 34, and the bolt has a wing nut 37 for clamping the block on the plate or sheet of glass.
From this description taken in connection with my drawings it will be apparent that the glass sheets or plates G and S may be mounted in correct position by means of the double work guide, clamped by the hold down blocks, and then the straight edges may be depressed to the sheet of glass for a working stroke of the roller or wheelcutter to quickly and with precision cut the desired size of sheet.
While the drawings illustrate and the specification describes a duplex appliance, it will of course be understood that the invention may be embodied in a single appliance.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a manually operated glass cutting appliance, the combination with a base board having an I-shaped work guide including a transversely arranged block and two right angle heads one at each end of the block, a similarly shaped holder having a transverse bar resting on the block and angle iron plates resting on the heads for maintaining the block and heads in rigid relation to each other, means passing through said block, heads and holder to retain the same in longitudinal adjusted relation to the base board, a hold down block located adjacent said work guide, means for securing said block in adjusted relation to said work guide, a straight edge having spaced resilient supports, means for adjusting the supports with relation to the work guide, a carrier mounted to travel on the straight edge and a glass cutting tool mounted in the carrier.
2. In a manually operated glass cutting appliance, the combination with a rectangular shaped base board, having a pair of parallel spaced rails,
mounted on the base board longitudinally thereof, and a pair of parallel spaced tracks intermediate the rails, of a depressible straight edge arranged transversely of the base board, resilient supports for the straight edge mounted for adjustment on the rails, a reciprocable cutting tool mounted on the straight edge, a hold down block mounted on one of the spaced tracks and means for securing the block in adjusted position on said one track.
