DANIEL J. ALLEN, OF LISBONVILLE, MISSOURI.
SPECIFICATION forming part of Letters Patent No. 341,306, dated May 4, 1886.
Application filed December 2, 1885. Serial No. 184,419.
v vented certain new and useful Improvements in lVashing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
rIhis invention relates to certain improvements in machines that may be adapted to be used either as a washing-,machine or a churn; and it maybe Said to consist in the devices and combination of devices hereinafter set forth, and pointed out in the claim. n
In the drawings, Figure l represents a sectional elevation of the upper part of a Washing-machine tank having the driving mechanism of my machine attached thereto. Fig. 2 is a side view of the driving mechanism from the left hand in Fig. l. Fig. 3 represents several detail views of the vibrating crosshead used in making up the machine. Fig. 4 is a perspective view of a portion ofthe cover ofthe machine and the slide which carries the shaft of the dasher or plunger. Fig. 5 is a detail elevation and an inverted view ofthe dasher. Fig.6 is a side view of the driving mechanism from the left hand in Fig. 1, the cross-head and one of the driving-wheels being removed from the driving-shaft; and Fig. 7 is a section through Fig. G on line g g.
It will be seen that the machine is of that class in which a reverse motion is imparted to the agitating device.
The lettersAA represent a pair of driving wheels or disks having formed upon one ol' their respective sides a segmental row of teeth. B, and a small segmental cam-surface, C, said cam-surface being located dametrically opposite the teeth. Upon the outer side of each of the wheels A and A', and extending about half-way around, as do the teeth B and the smaller cams O, a camsurface, D, is formed. This latter cam-surface is located diametricall y opposite the before-mentioned cam C.
A pair of standards, AN, are affixed to the cover of the Washing-machine tank lVI by any suitable means, and they are formed with laterally-projecting brace-arms N', by means of which the standards may be connected securely together. The outer ends of said brace- (No model.)
arms have eyes formed in them for the reception of transverse brace-rods d, which extend from the arms of one standard to those of the other, and so tend to form a strong and substantial framing for the driving mechanism of the machine. u
A driving-shaft, b, carrying a hand-crank, a, upon one end, is journaled in lthe upper portion of the standards, and the wheels A A are securely fixed thereon at such a distance apart as will correspond to the diameter, or a little more than the diameter, of the pinion F, located on the vertical dasher-shaft P. Said dasher-shaft P carries the dasher H upon its lower end, and it carries a vibrating crosshead, E, on its upper end; but said shaft is not rigidly xed in such cross-head; on the contrary, it should be free to revolve in its bearing in the cross-head.
The cross-head E is loosely mounted upon the driving-shaft b between the drivingwheels, and by contact of its respective sides with the small cams C as the driving-wheels are revolved it is adapted to carry the upper end of the dasher-shaft first alittle to one side and then to the other side, as will be explained farther on.
In the upper surface of the cover of the tank M a guiding-slot, e', is formed for the reception of the pinion-carrying slide J. A tongue, e, is formed upon the lower side of said slide, and when the slide is in place engages said slot, and during its vibratory movement holds it in proper position upon the cover of the machine.
The dasher-shaft l? passes through the pinn ion F, to which it is rigidly attached, and it passes downward through a hole, f, in the slide J, and through au oblong aperture, f, in the cover of the tank M. Upon each end of the slide J vertical projections J are formed, and are adapted to be respectively engaged by the cam-surfaces D upon the outer faces of the drivingwheels.
It is evident, then, that when the parts are arranged and located as regards each other as I have shown and described them the dashershaft I will be vibrated in a vertical line when the hand-crank a is rotated. For instance, it
will be observed that the small cams O move and guide the upper end of the dasher-shaft independently of the slide J and the cams D, which move and guide the lower end, thereby retaining said shaft in a vertical position during every part of its operation.
Anti-friction rollers-such as Lcan be located in or applied to the projections J of the slide J, so as to be engaged by the cams D, as may be desired.
Upon a continuous rotation of the handcrank a the pinion F will rst engage the teeth Having thus described my invention, what I claini is The combination of the standards N, located upon the tank, the driving-shaft b, journaled therein and carrying the driving-WheelsAAQ which are provided with a segmental row of teeth on their inner sides, a cross-head located between said wheels, cams C on the inner sides of the Wheels, for reciprocating said crosshead, dasher-shaft P, having its upper end journaled in said cross-head and carrying the pinion F and the dasher H and slide J, and cams D upon the outer sides of the drivewheels for reciprocating said slide, substantially as described and shown.
In testimony WhereofI afx my signature in presence of two Witnesses.
