My invention relates to apparatus for shearing metal and the object of my improvement is to perfect the operative construction, and to facilitate the presentation of the material to the ap- 5 paratus and its disposition after it has been acted upon.
'side view of an tion.
Figure 2 is an elevation the accompanying drawings, Figure 1 is a apparatus embodying my invenlooking from the right of Figure 1, the jaw being shown as closed down to cutting position.
Figure 3 is a sectional elevation on the line Figure 2, the frame 6| being shown turned down in position to receive the work 64, thereon.
Figure 4 is a detail ing the take-up perspective view, illustratconstruction of the bearing for the main shaft.
Figure 5 is a sectional elevation on the line Figure 1, looking in the direction of the arrows.
Figure dis a detail sectional view showing the connection of the actuating mechanism with the jaw.
Figure 7 is a detail 1-1,
Figure 8 is a detail elevation apparatus adjacent to sectional view on the line Figure 1.
of a portion of the the cutter edges looking swinging jaw secured to a oscillate in bearings in the members projecting from merals 66 (Figure 5) is a 3, to the jaw duits opening at the periphery of shaft 3, adapted to upper end of upright the frame 2. Nukey securing the shaft Numerals 9, 9 denote grease conthe ends of the shaft 3, and at said shaft within its bearings.
The ends of the shaft 3, are screw threaded, and caps 4, 4 internally screw-threaded engage the threads on the end wrench, for adjustment or of said shaft. are adapted at 65,
The caps to be engaged by a removal. The numeral 8 denotes a part shaped to form the lower portion of the bearing for the shaft 3. The lower surface of said part tapers inwardly and fits against and is adjustable along the corresponding Wall of the opening in the frame 2,
through which said shaft passes (Figures 4 and Numerals 5. 5 designate plates encircling the ends of the shaft 3, and adapted to bear against the surface of the frame 2, and outer ends of the portions 8, 8. Bolts 6, 6 pass through said plates and in screw-threaded apertures in the frame 2. Numerals l, 1 denote bronze plates interposed between the side surfaces of the jaw and the adjacent surfaces of the frame 2. The bolts 6, press the bronze plates 7 against jaw I thus serving to adjust the jaw laterally. The plates 1 have grease cups l0, and passages to supply grease to the contiguous surfaces of said jaw and plates. Numerals indicate wedges connected to the frame 2 by bolts l2, which serve to force said wedges between the plates 1 and adjacent surfaces of the frame 2 and to press said plates against the sides of the Jaw.
Power is communicated to the cutting apparatus by means of a belt 40 (Figure 9) passing over a pulley 69 upon the shaft 4|, mounted in bearings 4242. A spring 44, surrounding the shaft 4| between the bearings 42 presses collars 45-45 against said bearings and tends to keep the grease in said bearings. 22, 22 are flywheels on the shaft 4| 43, 43 are pinions on the shaft 4|. Numeral 38 denotes a shaft extending transversely across the frame 2 and adapted to turn in bearings 32 thereon. Numerals 2|, 2| designate gear wheels on the outer ends of said shaft with which the pinions 4343 mesh. Numerals 33, 33 (Figure 6) denote two arms, and 39 a connecting pin, of a crank upon the shaft 38. Numeral 29 indicates a connecting rod pivoted at its lower end upon the pin 39, and at its upper end upon a pin 36, extending transversely through the walls of a slot in the end 39, of the jaw Bronze plates 31 are interposed between the sides of the connecting rod 29, at its upper end and the side walls of said slot in the jaw Set screws 3|, 3| pass through the walls of said slot and engage the plates 31 to press the same against the connecting rod to adjust it laterally and thus obviate any lost action.
The jaw I has a knife 10, which shears past knife Illa on the frame 2 (Figures 1 and 2).
The gear wheels 2!, mesh with pinions 20 on a transverse shaft 23, fitted with a sprocket wheel 14, at its outer ends. The numeral l3 denotes a shaft parallel to the shaft 23, having sprocket wheel Bl at its outer ends. Numeral I9 designates a sprocket chain passing over and connecting the sprocket wheels l4 and 61.
Numeral l5 indicates a bevel gear on the shaft I3. Numeral l8 denotes a table at one side of the frame 2 at the delivery end of the apparatus. Numeral Z5 denotes a roller beneath the table l8, its shaft extending at right angles to the shaft I3, and having a bevel gear 24. Numeral l5 (Figures 2 and 9) designates a conveyor passing around, and actuated by a driving roller 25. The table l8 has slots 52 in its upper wall and the conveyor is provided with prongs l! which pass through said slots to engage any object on the table l8. Numeral 12 denotes a curved delivery surface extending from the cutter 10a to the table l8.
Numeral 4T designatesa table connected to the frame 2 by lugs 59 pivoted to the upper ends of vertical levers 48-which levers are secured to bolts 59 at their lower ends, that engage the frame 2. As said bolts are loosened levers 48 swing down lowering the table as illustrated in broken lines (Figure 8).
The following apparatus is used for handling large parts such as automobile frames. Numeral 54 (Figures 1 and 3) denotes a trough in the floor 68. Numeral 56 indicates a plate supported in the trough 54 by springs 55. Numeral 56a denotes a guide plate for the side of the carrier which may be adjusted laterally by hand screws 51. Numeral 58 designates a carrier provided with wheels 62, resting upon and adapted to travel longitudinally on the plate 56. The carrier 58 has a rigid fence 59 at one end and side to prevent work falling therefrom. Numeral Bl indicates a movable frame pivoted at 6!! to the the car 58, so as to swing in a vertical plane. The frame 5| is turned down and the work placed thereon as shown in Figure 3. The frame is then turned up dropping the work into side of "the carrier which is then manually pushed forward, and the work 64 is made to lean over to bring a. portion of it between the cutters (Figure 1). The fragments 13 slide down the incline 12 onto the table l8, from which they areremoved "by the prongs H on the conveyor l5.
Smaller articles are placed upon the table ET, and passed therefrom to the. cutters. With large parts there is apt to be lost motion between the work and the lower cutter as the work yields to the descending jaw l, the springs yield to the thrust.
What I claim is:
1. In an apparatus of the kind described, an oscillating jaw, two posts located opposite to each other adjacent to the sides of said jaw and spaced from the pivotal axis of. said jaw, and means for adjusting the distance apart of said posts.
2. In an apparatus of the kind described, an oscillating jaw, two posts located opposite to each other adjacent to the sides of said jaw and spaced from the pivotal axis of said jaw, and means for adjusting the distance apart of said posts, a plate interposed between one of said posts and the side of said jaw and means for adjusting said plate at right angles to the plane of oscillation of said jaw.
3. In an apparatus of. the kind described, the combination of a cutter, a trough-like structure passing transversely in front of said cutter, a
plate in said structure forming a Way for a car-- rier, springs supporting said plate, and a carrier adapted to travel upon said plate.
4. In an apparatus of the kind described, the combination of a cutter; a plate forming a way for a carrier and extending transversely in front of said cutter adjacent thereto; springs supporting said plate; and a carrier adapted to travel upon said plate, substantially I as and for the purpose described.
5. In a machine for shearing automobile frames, an oscillating jaw having a shaft; a bearing for said shaft, two posts located opposite each other adjacent to the sides of said jaw and means for adjusting and fixing the distance apart between said posts, said jaw having a shearing edge; a stationary shearing edge adapted to coact with said shearing edge upon said aw; and a spring-supported plate adapted to receive an automobile frame and hold a portion thereof adjacent to said stationary shearing edge and in the line of travel of said shearing edge on said jaw.
