REVERSING MECHANISM.
SPECIFICATION forming part of Letters Patent No. 688,123, dated December 3, 190i Application filed February 26, 1901. Serial No. 48,952. (No model.)
To all whom it may concern:
Beit known that I, FRANK CLARENCE RICE, a citizen of the United States, and a resident of Jamestown, in the county of Chautauqua and State of New York, have invented a new and Improved Reversing Mechanism,of which the following is a full, clear, and exact description.
The invention relates to reversing m echanism such as shown and described in the Letters Patent of the United States No. 633,783, granted to George V. Blackstone on September 26, 1899.
The object of the present invention is to provide a new and improved reversing mechanism for use on washing-machines, churns, and other machines and devices to rotate the dasher or other part alternately in opposite directions and arranged to reduce friction to a minimum and to allow of running the machine with comparatively little power.
The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a side elevation of the improvement as applied toa washing-machine. Fig. 2 is an enlarged plan view of part of the improvement. Fig. 3 is a perspective view of the same. Fig. 4t is a plan view'of one of the loose gear-wheels. Fig. 5 is a sectional side elevation of a modified form of driving gearwheel, and Fig. 6 is a face view of the same.
The washing-machine on which the improvement is applied is provided with a suitable box A, in which is mounted to revolve a dasher B, mounted to slide on and to turn' with a dasher-shaft C, journaled in suitable bearings arranged in a bracket D, secured to the cover or lid E of the box A. In the bracket D is journaled, at a right angle to the shaft C, a driving-shaft F, having a suitable crank-arm F', under the control of the operator,for turning the shaft F in either direction.
On the inner end of the shaft F is secured a bevel-pinion G, in mesh at opposite sides with bevel gear-wheels H H', mounted to rotate loosely on the shaft C. On the latter is secured a locking device consisting of a member I, secured to said shaft C and carrying a bolt I', on which is mounted to slide vertically a movable member I2, carrying at its upper and lower ends friction-rollers I3 I4, adapted to be engaged by a projection in the form of a cam J, held on the face of the pinion G and arranged in such a manner that when the pinion G is turned and the two gearwheels H and H' are rotated then the cam alternately moves in engagement with the friction-rollers I3 I4 to impart an up-and-down sliding motion to the member I2 to engage the friction-rollers I3 Itl with recesses H2 H3, formed in the webs of the gear-wheels H H', respectively. The said friction-rollers I3 I4 are also adapted to travel on cam-surfaces H4, formed on the webs of the bevel gear-Wheels H H' and leading from the recesses H2 H3, so that when the cam J has engaged,say, the friction-roller IB and moved the member I2 in an upward direction then the other frictionroller I1 in moving out of its recess H2 is brought to the cam-surface H4 to push the slidable member I2 into a final uppermost position on a further rotation of the pinion G and the gear-wheels H H'. In a similar manner the friction-roller I3 engages the cam-surface H4 on the under side of the web of the gear-wheel H' at the time the cam J acts on the friction-roller I4 and pushes the member I2 in a downward direction.
From the foregoing it will be seen that by having the friction-rollers I3 I4 traveling on the cam J the incident friction is reduced to a minimum,and consequentlyit requirescomparatively little power on the part of the operator to rotate the shaft F. It will further be seen that by having the cam-surfaces H4 the movable member I2 is thrown far enough during each stroke to insure a positive engagement of the corresponding friction-roller l3 or I4 with the recess H2 or H3 in the gearwheels H H. v In order to still further decrease the friction, the projection on cam J is preferably made in the form of a friction-roller J', journaled on a stud J 2, secured to the driving-pinion G eccentrically to the shaft F, so that the IOO friction-rollers l Ii travel With their peripheral surfaces on the peripheral surface of the friction-roller J,When the latter alternately engages the said friction-rollers upon rotating the pinion G, as above described.
It is evident from the foregoing that when the shaft F is rot-ated in one direction the shaft C and the dasher B are alternately revolved in opposite directions, the gearing being so proportioned that it requires one and one-half revolutions of the pinion G to give one full turn to the gear-wheels H H', and consequently after another one and one-half turn of the pinion G the cam or friction-roller J stands in an opposite position to that which it had upon the previous shifting of the movable, member I2 of the locking device, and as the gear-wheels H H now have-each made a full revolution the corresponding recesses are directly or nearly opposite each other, and the shifting ofthe movable member I2 can now take place to move the friction-rollers I3 or I4 out of mesh with the corresponding recess and` in mesh with the'recess in the other gearwheel H or H.
Havingthus fully described my invention, I claiml as neviT and desire to secure by Letters Patent* 1. A reversing mechanism, comprising a driving-pinion, a projection on said pinion, gear-.wheels in mesh with said pinion at opposite sides thereof, anda locking device on the shaft to be driven and having a fixed member secured to the shaft anda locking member mounted to slide on the Xed member, and antifriction-rollers on the ends of said movable member, and adapted to be engaged by said projection-on the pinion, to throwthe movable locking member alternately into engagement with` lthe said gear-wheels, as set forth.
2. Areversing mechanism comprising bevel gear-wheels having shoulders and inclines, a
' driving-pinion, for-driving said gear-Wheelsin opposite directions, a locking member adapted to be shifted, to alternately engage the shoulgear-Wheels having shoulders and inclines, a driving-pinion,for driving said gear-Wheelsin v opposite directions,a lookin g member adapted to be shifted, to alternately engage the shoulders and inclines of the gear-Wheels, means moving with said pinion for shifting said locking member, and antifriction-rollers at the ends of 'said locking member, to engage the shoulders and inclines of the gear-wheels alternately upon shifting the member, as set forth.
4. A reversing mechanism, comprising a drivingpinion,a stu'd projecting from the free end of the drivin g-pinion eccentric to the shaft of the pinion a friction-roller journaled on the said stud, gear-wheels in mesh With the driving-pinion at opposite sides thereof, and a 'locking device on the shaft to be driven and having a movable locking member adapted to engage said friction-roller and throw the locking member alternately into engagement with saidgear-Wheels, as set forth.
5. A reversing mechanism, comprising a driving-pinion, a frictionroller journaledV on the free end of said pinion, gear-Wheels in mesh with the driving-pinion at opposite sides thereof, the said gear-Wheels having recesses formed in their Webs and cam-surfaces leading from the recesses a locking device on the shaft to be driven and having a movablelocking member, and friction-rollers journaled on the locking member and adapted to engage the said friction-roller and throw the locking member alternatelyT into engagement with said recesses in the gear-Wheels, as set forth.
6. A reversing mechanism, comprising a driving-pinion, a projection on said pinion,
gear-Wheels in mesh with said pinion at opposite sides thereof, the saidgear-Wheels having recesses in their Webs and cam-surfaces l leading from the recesses, and a lockingmember adapted to be engaged and shifted by the said projection on the pinion to alternately engage the recesses in the gear-Wheels, the said locking device when moving out of the recess of one gear-Wheel engaging the camsurface of said gear-Wheel, for the purposeset forth.
In testimony whereof I have signed my name to this specification inthe presence of two subscribing. witnesses.
