6 Claims.
This invention relates to cutting machines, and it is particularly applicable to machines for cutting pieces from stock that is in the form of rods, tubes, etc.
General objects of the invention are to provide a cutting machine having compactness, having high operating speed, having a high degree of safety. and having a high degree of operating ease and convenience.
Various additional and specific objects of the invention will be apparent to those skilled in the art from the following disclosure of forms of theinvention which are at present preferred by me.
Fig. 1 of the drawings is a perspective view of the machine with the cover open and with part of the cover broken away.
Fig. 2 is a side elevation with parts broken away, looking from the right-hand side of the machine.
Fi 3 is a top plan view of the machine with the cover closed.
Fig. 4.15 an elevation of th upper portion of the machine, looking from the right-hand side of the machine, with the cover closed.
Fig. shows a modification. The view is an elevation looking from the right-hand side of the machine, with the cover open and part of it broken away.
Reference will first be had to Figs. 1, 2, 3, and 4. The dangerous parts of the machine are sub-' stantially completely enclosed by an enclosure which includes a housing I and a hollow cover 2 that is hinged to the housing. A shaft 4 traverses the housing i and swingably supports a frame 5 (Fig. 2) which is adapted to swing back and forth. The upper portion of the frame 5 projects above the top of the housing I and has Journalled therein a cutter shaft 5 on which is mounted a cutting disc I. The disc I ma be a suitable saw, or it may be an abrasive disc such as, for example, a molded phenolic disc having abrasive incorporated therein. Mounted on the is a second rod '20 which can be adjusted forwardly and backwardly oi the machine and be held in adjusted position by thumb screw 2| which engages a fiat on rod 20. The free end of rod 20 is provided with a screw 22 on the end of which is mounted a stop 22. The stop 22' can be ad- Justed laterally of the machine by turning screw 22, and can be locked inplace by winged lock-nut 2.4. In operation stock 25 in the form of a tube, rod or the like, is supported at one point by V- block l4 and clamped at another point by vise I5. By suitable adjustment of rod I5, block ll, rod 20, and stop 22, the stop 22' may be aligned with the end of the rod-like stock 25 from which pieces are to be cut. Thus stop 22' is an adjustable one against which the end ofthe stock 25 can be pushed; and it fixes the length of successive pieces which it may be desired to cut oil.
Vise l5 includes fixed lower Jaws 39 and it which are aligned, and which are separated by a slot 32 (Fig. 1) which runs forwardly and backwardly of the machine. The vise also includes a movable upper member 34 having aligned laws 35 I and 35 which are separated by slot 31 that 001'- lower portion of frame 5 is an electric motor 8 which, through a plurality of V-belts 9, is adapted to drive cutter shaft *6 and thereby rotate the cutting disc 1.
At the top of the housing i there is a table l2 on which is mounted a stationary V-support l4 and a vise designated as a whole as l5. Projecting laterally from the vise I5 is a rod i6 adapted to be adjusted in position and be clamped in any adiusted position by a clamp bolt il. Rod l6 carries a block i8 which is adapted to be adjusted lengthwise and rotatably of rod i6 and be held in any adjusted position by thumb screw l9. Proletting from block l8, perpendicularly of rod 16,
responds to and is directly over the slot 32. The upper vise member 34 is mounted on a vertically reciprocatable rod 40 which is connected by transverse pin 4i with the upper end of a tension link designated as a whole by 42. The lower end of the tension link 42 is connected by a transverse pin 44 with a treadle 45. A tension spring 45 (Fig. 2)
biases the treadle in upper (non-operated) position. A bolt 41 (Fig. 1) may have a nose that enters a longitudinal groove (not shown) in rod 40, to prevent any rotation of the rod as it is reciprocated.
In operation the cover 2 of the housing is closed, as shown in Figs. 3 and 4. This cover is provided with aligned openings at 2' and 2' (Figs. 3 and 4) so that the rod-like stock 25 can be inserted from ating link 49. Clamped to link 49 by bolt 59 is a hand lever 5|; and interfitting serrations at 52 (Fig. 1) prevent any angular slippage between link 49 and hand lever 51. Nevertheless, the angle between hand lever 5i and link 43 can be adjusted by loosening bolt 50. Link ll is pivotally forwardly, bringing the cutting disc 1 into cutting relationship with the stock 25 held'in vise II and. thereby cutting off the desired piece from the stock As the cutting disc 10 moves forwardly,
it passes into slots 31 and 32 between the respective pairs of upper and lower jaws of the vise. When the lever ii is released, the frame F swings back to its rearward position due to the unbalanced weight applied to the frame 5 by motor 8. For convenience of illustration, the forward position of frame 5 and associated parts is shown in full lines in Fig. 2, and the rear position of the frame 6 and the cutter I is shown in dot-dash lines. a
The housing may be ventilated by various sets of louvers such as the set shown at Bl in Fig. 1. An adjustable stop, preferably rubber -tipped, is provided at 62 (Fig. 2) to limit the backward movement of swinging frame I. A second adjustable stop, also preferably rubber tipped, is provided at 64 to limit the forward movement of swinging frame 5. At the front of the housing a hand wheel 66 may be provided to adjust stop 64. Included in the treadle operated tension link 42 there is preferably a turn buckle element such as 86 to adjust the length of link 42 to thereby adapt the vise l5 for handling stock of different diameters. The electric motor 8 which drives the cutting disc may be controlled by start and stop push buttons 61 and 68 respectively. To aid in unscrewing nut 69 when it is desired to replace cutter 1 means may be provided to temporarily lock the cutter shaft 6 against rotation. In Fig. 1 there is shown a plunger III which is biased upwardly by a spring (not shown). This plunger is adapted to be temporarily depressed by hand, its lower end engaging a flat on, or a hollow in, shaft 6 to hold the shaft against rotation when a wrench is applied to nut.
In operating the form of invention shown in Figs. 1 through 4, the stock 25 is advanced by hand after each piece is out off. After the stock has been advanced, treadle 45 is operated to clamp it in the vise l5, and then the hand lever 5| is operated to swing the cutting disc 1 forward to cut oil the piece. In the modification shown in Fig. 5 the stock is also advanced by hand, but the operation of both the vise and the cutting disc are under the control of a single hand lever. In Fig. 5 the hand lever 5i operates through links 49 and 55 to advance the swinging frame in the same manner as in Figs. 1 through 4. For the sake of illustration, hand lever ii is shown in Fig. 5 as having been adjusted, through the loosening ofnut 59, to a different angular relationship with respect to link 49.
At 10 there is an air valve assembly having a plunger I I that is biased outwardly and is adapted to be pressed inwardly by lever I2. The valve is of known type and its construction is such that with the plunger II in outward position, air line H is vented. However, with the plunger II indepressed position, the venting of line I4 is closed and air pressure is delivered to line I4 from air' supply line 15. Lever I2 is biased in non-operated position by spring 16, the tension of which is adjustable by turn buckle 11. A second spring 18, which is stronger than spring 16, is adjustably connected by turn buckle 18 with the pivot pin 56 of the swinging frame 5 (see Fig. 2). At I 5a the machine is provided with a vise having fixed jaws at 80 and movable Jaws at 8]. These jaws are slotted after the fashion of the jaws shown in Fig. 1 to permit the cutter I to advance. The 5 movable jaw 8| is mounted for reciprocation forwardly and 'backwardly of the machine and is biased into'vise-opeir position by tension spring 82. A pneumatic cylinder assembly at 83 is connected to jaw 8! to advance the Jaw into viseclosed position upon air pressure being delivered to the cylinder at 83.
Stock having been put in place in the vise "a, hand lever II is operated. During the initial movement of hand lever Ii air valve lever. 12 is operated causing air pressure to be delivered to line 14 and cylinder 83. This advances the movable jaws at 8| and clamps the stock in the vise lid. The continued movement of hand lever II brings the cutting disc 1 into cutting relationship with the stock clamped in the vise, just as in the case of Figs. 1 through 4. Upon completion of the cut, hand lever ii is merely released. The unbalanced weight applied by motor I (Fig. 2) returns the cutter to the position shown in Fig. 5: and spring 16 retracts lever 12, thereby permitting the closing of air valve Ill and the venting of air line 14. Thus the vise is restored to open position.
In compliance with the patent statutes, I have disclosed the best form in which I have contemplated applying my invention, but it will be realized that the disclosure is illustrative of the invention rather than limiting the scope of the same. 4
