POWER-TRANSMITTING DEVICE FOR HAND-DRIVEN MECHANISMS.
SPECIFICATION forming part of Letters Patent No. 708,286, dated September 2, 1902;.
' Application filed May 6.1902. Serial IIo. 106,115. (No model.)
To @ZZ whom, it' may concern:
Be it known that I, FREDERICK XV. IVILD, Jr., of the city of Baltimore and State of Maryland, have invented certain Improvements in Power-Transmitting Devices forIIand-Driven Machines, of which the following is a specification.
In labeling and other machines which are operated by hand and in which the drivingshaft thereof has to be rotated in one direction only the constant turning of the crankhandie becomes monotonous and irksome, and it is usual for the operator to turn first with one hand and then vwith the other for relief; butsuch change affords but a partial relief for the reason that the direction of motion is not altered.
The object of the present invention is therefore the construction of a mechanism which is interposed between the crank-handle and the driving-shaft of the machine -or is applied to some driven portion of the machine, whereby the direction of turning of the crank-handle may be reversed without affecting that of the driving-shaft, which will still rotate as before.
In the description of the said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in Which- Figure lis an exterior front view of the improved apparatus, and Fig. 2 a central Vertical section of the same. Fig. 3 is a section of Fig. 2 taken on the irregular dotted line A A and looking in the direction of the straight arrow. Figs. 4, 5, 6, and 7 are details of the mechanism, the last named being on an enlarged scale.
Referring now to the drawings, 1 is a spindle adapted for application to the drivingshaft of the machine to be operated, and itis bored to iit thesaid driving-shaft, which is not shown. The direction of the rotation of lthe said spindle when the same is seen from the front of the apparatus in the present case is the reverse of that ofthe hands of a clock. The bored end of the spindle 1 rotatesv within a bearing formed in one side of a casing :3, and the other rests loosely within the hul;I 3 of a spur gear-wheel 4, which hub passes loosely `through and is sustained by tlm-side of the said casing. l
20, which is loose on the spindle 5 is a crank-handle fastened in any suitable manner to the exposed or outer end of the hub 3 of the spur gear-wheel 4. The inner end of the said hub is bored, and into the cavity thereby formed is forced tightly the ring 7, having the internal ratchet-teeth 9 and the channel 10, which extends entirely through the hub 3 for a purpose hereinafter described. A face view of the wheel 3 is shown in Fig. 4:.
Seated loosely in a transverse slot 12 in the spindle 1 is a sliding bolt 13, having its ends beveled in the same direction.` This bolt, two views of which on an enlarged scale are shown in Fig. 7, has a length which is slightly less than the distance from the root of one of the ratchet-teeth 9 to the circumference of the spindle diametrically opposite. This construction admits of the one end of the sliding bolt being-in contact with the root of one of the ratchet-teeth while its other end is clear of the points of the said teeth. l/Vhen the crank-handle is turned in the direction indicated by the curved arrow in full lines in Fig. 1, which direction is indicated also by the curved arrow in full lines in Fig. 3, one end of the sliding bolt 13 is forced into locking contact with one of the ratchet-teeth lby the inclined surface of another tooth riding over the other end of the said bolt, and the rotary motion of the spur gear-wheel 4 is therefore communicated directly to the spindle through the agency of the sliding bolt 13. Should the crank-handle be turned in the opposite direction, the sliding bolt 13 becomes inoperative and ceases to be a driver, and should no other mechanism be employed the spindle would remain stationary. i
I will now describe the mechanism whereby in the backward rotation of the crank-handle or that in the direction indicated by the dotted curved arrows in Figs. 1 and 3 the spindle 1 is caused to continue its rotation in the same direction or that before specified.
15 is a fixed shaft secured to the casing 2 in any appropriate manner and preferably by means of screws 16. On this shaft'is the loose spur gear-wheel 17, in mesh with the one 4 and also the loose spur gear-wheel 19, whichis locked to the one 17 and imparts rotary motionlo the corresponding gear-wheel 1, through IOO the medium of the idle gear-wheel 21, which rotates about the stud 23, projecting inward from the side of the casing 2. The spur gear-wheel 2O is provided with a ring 24 like the one 7, having the ratchet-teeth 25 similar to the ones 9.
27 is a bolt with beveled ends, which like the one 13 slides in a slot in the spindle 1, and its position relatively to the ratchetteeth 25 Within the wheel 20 is the same as that of the one 13 to the teeth 9 within the wheel 4.
Fig. 5 is an exterior view of the spindle l, showing the slots for the bolts 13 and 27, and Fig. 6 is a cross-section of Fig. 5.
With the construction described when the crank-handle is reversed or moved in the direction indicated by the dotted curved arrows the gear-wheel 2O is caused to rotate in an opposite direction to that of the crankhandle (or in the direction first described with respect to the spindle) through the medium of the sliding bolt 27, the other bolt at the time being inoperative.
For convenience in putting together and taking apart the apparatus the casing, which serves to protect the mechanism from dirt, is made in two parts or sections held t0- gether by screws, and the said casing is provided with a lug 30, whereby it is supported from some xed device, which may be a part of the machine to which the apparatus is applied.
The slot 10, before referred to as extending radially from the interior of the hub 3 of the gear-wheel 4 and longitudinally the full length of the hub, including the ring 7, is to allow of the withdrawal of the said Wheel from the spindle l when the two sections of the casing are separated, theV projecting end of the sliding bolt 13 passing through the said channel.
I claim as my invention- In a power-transmitting mechanism for the purpose described, a spindle which has to be rotated in a certain direction, a gear-wheel loose on the said spindle and to which power is applied, a ratchet mechanism constructed to transmit rotary movement from the said gear-wheel to the spindle when the said gear- Vwheel is rotated in one direction only, or that to be taken by the spindle, a second gear- Wheel loose on the said spindle with ratchet mechanism which in etect is the same as the iirst, combined with a train of gearing driven from the first gear-wheel, whereby in the reversal in direction of the first gear-Wheel, the second gear-Wheel is caused to rotate in an opposite direction to that ot' the first, thereby continuing the rotation of the spindle in the first-described and required direction, substantially as specified.
