W STEERS MACHINE FOR SAWING METAL.
Patented Nov. 25, 1890. I
UNITED STATES PATENT OFFICE.
\VILLIAM STEERS, OF BOSTON, MASSACHUSETTS.
MACHINE FOR SAWING METAL.
SPECIFICATION forming part of Letters Patent No. 441,597, dated November 25, 1890. Application filed September 4, 1890- Serial No. 363,907. (No model.)
To all whom. it may concern.-
Be it known that 1, WILLIAM STEERS, of the city of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Cutting Cold Metal, of which the following, taken in connection with the accompanying drawings, is a specification.
The object of my invention is to provide an automatic machine for cutting cold metals in a simple and expeditious manner. I attain this object by the mechanism shown in the accompanying drawings, in Which Figure 1 is a front elevation. Fig. 2 is a plan of the top of the same. Fig. 3 is a detail view in section to show the ball-bearing for the worm; Fig. 4, a section on line y y of Fig. 1; Fig. 5, a section on line a: 00 of Fig. 4.
Similarletters refer to similar parts throughout the several views.
Referring to the drawings, A, Fig. 1, shows the main column or standard with sleeve A, having brackets A and A with bearings O O for the saw-shaft C.
B, Fig. 1, is the actuating-shaft with its worm P and bevel-gears Z) and d".
B, Fig. 1, is a crank for operating the shaft G.
B and B are the ratchet-wheel and pawl.
B is a slotted arm to which the pawl is attachle d. b is a disk with slot 1) and crank- C, Fig. 1, is a shaft resting in bearings O O to which the gear a and the saw O are attached.
D, Fig. 1, is a shaft resting in bearings O O on a bracket 0 E, Fig. 1, is the driving-shaft.
E, Fig. 1, is the pulley or driving-Wheel.
F F and f f, Fig. 1, are screw-clamps for holding the work in position.
O is a guide for preventing the saw from springing out of position.
0, Fig. 1, is an ordinary oil-cup.
G, Figs. 1, 4, and 5, shows the rod for op erating the feed-motion.
H, Figs. 4 and 5, shows the nut, and I the feather moving in the spline of the stand ard A.
J J, Figs. 1, 4, and 5, show the setscreWs for keeping the feather in position.
upon which the worm P revolves.
The operation of the machine is as follows: The sleeve A, with its brackets A A shaft O, and bearings O 0 form acarriage for the saw. Said carriage, with the saw, is moved up and down on the standard A by the rod G and crank B, and is prevented from turning by the nut I-I moving in spline and feather I. The metal to be cut is placed in the receptacle at the base of the machine and clamped and held firmly by the screw-clamps F F and ff. The saw-carriage is then moved down until the saw touches the metal to be cut. The variable feed-motion is then adjusted by moving the crank-pin b in the slot in the disk b, from the center of the disk, making an eccentric feed-motion for the ratchet and pawl. The motion can be regulated to feed fast or slow by taking in more or less teeth at each revolution of the eccentric. Upon the bracket A of the saw-carriage A is the ball-bearing for the worm P. The worm P engages the gear-wheel c on shaft C. Said worm moves vertically on the actuating-rod B in the spline pibeing prevented from turning by the feather p. The anti-friction balls relieve the strain upon the bearing of the worm shown in section in Fig. 8. The actuating-rod B is revolved by the driving-wheel E, pinion c, and gear-wheel d and bevel gears b d. Thesaw-carriage, with the saw, can be raised very easily, after the metal has been cut, to a position to allow the work to be taken out. The rod G is prevented from reciprocating by a shoulder bearing against the under side of the cap on the top of the standard A. This shoulder prevents the rod from moving up the sleeve 'on the crank B, and the nut g prevents it from moving down.
This machine can be operated by poweror hand-crank motion.
I claim 1. In a machine for cutting cold iron, steel, and other metals, the combination of the movable saw-carriage and saw with the actuating device and variable-feed mechanism, substantially as described, and for the purpose set forth.
2. In a machine for cutting cold metals, the combination of a movable saw-carriage and p p, Fig. 3, show the anti-friction balls standard, the actuating-shaft having a slotted disk, with the non-reciprocating feed-motion rod, having an adjustable arm, ratchet, and pawl, substantially as described, and for the purpose set forth.
3. In a machine for cutting cold metals, the combination of the Worm P, arranged and adapted to revolve with and reciprocate upon the actuating-shaft B, with the anti-fricti0n balls 13 17, inserted in suitable grooves between the worm P and the bracket A substantially as described, and for the purpose set forth.
4. In a machine for cutting cold metals, the combination of the 11011-18Cl procating shaft B, disk Zahaving a slot and crank-pin, with the slotted arm 13', carrying pawl B ratchetwheel B and non-reciprocating shaft G, arranged and adapted to operate together, substantially as described, and for the purpose set forth.
In a machine for cutting cold metals, the
combination of the standard A, carriage A,
