MECHANICAL MOVEMENT.
SPECIFICATION forming part of Letters Patent Nol. 795,189, dated July 18, 1905,
Application filed February 27, 1905. Serial No. 247.421.
To all whom/if; may concern:
.Be it known that we, ROBERT T. BELL and CHARLES H. VEITE, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.
Our invention relates to improvements for producing reciprocatory motion of a member simultaneously revolving about an aXis disposed at an angle to the line of such reciprocatory motion.
The object of our invention is to provide a machine of this character of the simplest possible construction.
Our invention consists of a shaft journaled in a suitable frame and having -an endless spiral groove or track and a longitudinal groove or track, a block mounted on the shaft to slide lengthwise thereof, a pin mounted within the block adapted to be engaged b y the spiral track, a gear housed in the block adapted to be turned with the shaft by the longitudinal track or to slide lengthwise of the shaft with the block, an additional shaft mounted in the block at an angle to its line of motion, a member mounted on the additional shaft adapted to be rotated by the gear housed in the block, and means for preventing the block from turning with the shaft.
Our invention also consists in the parts and combination and arrangement of parts as herein described.
ln the drawings, Figure l is a side elevation of our invention connected by a chuck to a iexible shaft, a portion of which is shown. Fig. 2 is a plan of Fig. 1, excepting that a portion of the frame is broken away. Fig. 3 is a section on the line fu fu of Fig. 2. Fig. 4 is a section on the line w lo of Fig. 2. Fig. 5 is a section on the line .fc a' of Fig. 2. Fig. 6 is a longitudinal section of the block on the line y y of Eig. 2 and also showing a portion of the grooved shaft, the pin, and retainingscrew and a portion of the guide-rod in elevation. Fig. 7 is a longitudinal section of the block and portions of the angularly-dsposed members on the line e, Fig. 1, also showing a portion of the grooved shaft and pin and portions of the angularly-disposed shafts in elevation. Fig. Sis a perspective view of the pin. Fig. 9 is an elevation of one of the angularly-disposed members. Fig. 10 is an elevation of one of the angularly-disposed shafts.
The construction of our invention is as follows, reference being had to the drawings:
The frame 1, preferably constructed so as to form a convenient handle for the entire machine, has the shaft 2 journaled in the bearings 3 and 4 near its ends. The bearing 3 is preferably a removable one, while the bearing 4 may be adjusted to take up the wear of the shaft 2, so as to effectively prevent end play of the latter. Also mounted in the frame 1 parallel with the shaft2 is the guiderod 5. Mounted to slide on the shaft 2 and the guide 5 are the blocks 6 and 7. These blocks are recessed to form housings for the double bevel-gears 8 and 9. respectively. The shaft 2 has a longitudinal groove or keyway 10, and the bevel-gears 8 and 9 have feathers projecting into the groove 10, so that the bevelgears are compelled to revolve with the shaft and may also slide longitudinallythereof with the blocks 6 and 7. To produce the reciprocatory motion of the blocks, the shaft 2 is provided with endless spiral grooves 11 and 12, and the pins 13 and 14 are housed in the blocks 6 and 7, respectively, so as to bear in the endless spiral grooves 11 and 12, respectively. These grooves are so disposed on the shaft 2 that the blocks will move in opposite directions relative to each other. They are represented in the drawings in their' positions nearest to each other-that is, when the pins 13 and 14 are at the adjacent reversing-points of their respective grooves.
The pin 13 or 111 is composed of the cylindrical portion 15 and widened portion 16. The block 6 or 7 is provided with a recess 17 to receive'the widened portion 16 of the pin and a smaller opening' 18 to receive the cylindrical portion l5 of the pin, whereby a pivotal.bearing is formed for the pin inthe block. The recess 17 extends far enough upward into the block to permit the pin to be raised above the opening provided for the grooved shaft 2. After the grooved shaft 2 has been inserted through the openings provided for it and through the bevel-gears 8 and 9 the pins 13 and 14 may drop into their grooves in the shaft. The smaller opening 18 is threaded to receive a screw 19, which is adapted to bear on the upper end of the pin 13 or 14 and hold it in the spiral groove.
Each block 6 or 7 is provided with the studs 20, which form shafts for the members 21 at right angles to the grooved shaft 2. The ends of the members 21 are provided with bevel-gears meshing with the bevel-gears 8 and 9, slidably mounted on the grooved shaft 2. Upon these members are mounted the cylinders 22, of any suitable material. Preferably the studs 2O are braced by the yokes 23 near their outer ends.
The operation of the machine is as follows: The shaft 2 is rotated by a convenient means, such as the flexible shaft here shown, whereupon the blocks 6 and 7 will be made to traverse the shaft by the spiral grooves. The pin 13 or 14 being oblong in cross-section where it bears in the grooves will not change its direction at the crossing-places 24 of the grooves, but only at the final turning-point 25, therefore the blocks will continuously and with uniform speed reciprocate and carry the bevel-gears 8 and 9 lwith them; but at the same time these bevel-gears will be rotated because of their feathered connection with the shaft 2 and will rotate the members 21 and the cylinders mounted thereon by means of the bevel -gears These cylinders, it is obvious, will be caused to rotate in opposite directions, so that their effect upon the movement of the machine as a whole will be m'l. Likewise the movements of the blocks 6 and 7 are opposite, so that they will not disturb the equilibrium of the machine. Obviously these features would be necessary in a portable machine such as the one here illustrated, because the application of power to the machine would otherwise place it beyond the control of the operator.
It will be readily seen that our machine is applicable toan extended variety of abradin gmachines-such as grinders, polishers, or lathes as well as to many other kinds of machines, among which might be mentioned winding and spinning machines.
