.COMPLETE SPECIFICATION.
Improvements in Reversing Mechanism applicable to Washing
and other Machines.
I, GEORGE VANDERGRIFT BLACKSTONE, Manufacturer, of Jamestown, in the
County of Chautauqua, and State of New York, United States of America, do
hereby declare the nature of my invention for improvements in reversing
mechanism applicable to washing and other machines, and in what manner the
same is to be performed, to be particularly described and ascertained in and by.
the following statement:-
The object of the invention is to provide a new or improved gearing for
washing and other machines, which is simple and durable in construction,
requiring but little power to operate the machine and arranged when applied to
La washing machine to insure a thorough washing of clothes, without injury to
the same.
:
A practical embodiment of my 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 figures.
Figure 1 is a side elevation of the improvements applied to a washing
machine;
:
Figure 2 is a transverse section of the gearing, for the washing machine, the
section being on the line 2-2 in Figure 1;
Figure 3 is a sectional plan view of the improvement, on the line 3-3 in
Figure 1;

Figure 4 is an enlarged sectional plan view of the reversing locking device
on the dasher shaft;
Figure 5 is a sectional side elevation of the same, on the line 5-5 in
Figure 4; and
Figure 6 is a plan view of one of the gear wheels, with parts broken away.
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, bolted or otherwise secured to the cover or lid E of the box A.
On the dasher shaft C above the lid E, is arranged a locking device F, having
a member F secured to the dasher shaft C, and a member F2 fitted to slide verti-
cally in the fixed member F¹. The movable member F is provided for this
purpose with a vertical elongated slot F3, through which extends a bolt F+
secured in the sides of the fixed member F, which is preferably fork-shaped, as
indicated in Figure 4,. for the.movable. member F2 to slide in the forked piece.
The movable member F is provided above and below the slot F3 with transverse
bores containing spiral springs G, pressing with their ends against the inner
surface of the forked arms of the fixed member F¹, as is plainly shown in
Figure 4, so as to hold the movable member F³, by the springs, in either an up
or down position, the springs permitting, however, a free up and down sliding
movement of the movable member in the manner hereinafter more fully
described.
The lower and upper ends of the movable member F3 are formed with cam

page_text: lugs F5, F6, adapted to engage recesses H2, H3 respectively, formed in the bevel
gear wheels H, H', mounted to rotate loosely on the shaft C, below and above
the locking device F, as is plainly indicated in Figures 1 and 2. The bevel
gear wheels H, H' are in mesh with opposite sides of a bevel pinion I, secured
on a shaft J, mounted to rotate in bearings on the bracket D, and on the outer
end of the shaft J, is secured a wheel K, having a handle K¹ for turning the
wheel K and the shaft J, to rotate the bevel pinion I, which in turn rotates the
gear wheels H, H¹ in opposite directions.
On the inner face of the pinion I, is secured or formed a cam I', adapted to
alternately engage the cam lugs F5 and F on the locking member F³, to slide
the latter either up or down, to bring the said lugs in or out of mesh with the
gear wheels H, H³, so that when the movable member F2 is, by its lug F³, in
mesh with the bevel gear wheel H, then the rotary motion of the gear wheel H
is transmitted by the locking device to the dasher shaft C, to rotate the dasher B
in one direction; but when the movable member F is shifted upward and the
lug F5 is moved out of mesh with the gear wheel H, and its lug F is moved
in mesh with the gear wheel H¹, then the rotary motion of the latter is trans-
mitted by the locking device F to the shaft and the dasher B, but in an
inverse direction to that previously given to the gear wheel H and clutch F.
It is evident from the foregoing, that when the shaft J is rotated 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 I to give one full turn to the gear wheels H and H¹,
and consequently, after every one and a half turn of the pinion I, the cam I'
stands in an opposite position to that which it had upon the previous shifting
of the movable member of the locking device, and as the wheels H, H', now
have each made a full revolution, the corresponding recesses H2, H3 are directly
or nearly opposite each other, and the shifting of the movable member can take
place, to move one of the lugs F5 and F6 out of mesh with the corresponding
recess and in mesh with the recess in the other wheel H' or H.
The device is very simple and durable in construction, is not liable to get out
of order, and requires but little power to run the same, to wash the clothes
properly by the action of the dasher B revolving alternately in opposite
directions.
Having now fully described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:-
In a reversing gear applicable to washing and other machines, the provision
of two bevel wheels loose on the driven shaft and adapted to be locked thereto,
one at a time, by a slide held to rotate with said shaft and moved longitudinally
thereof by a cam on the driving bevel pinion in mesh at all times with said
bevel wheels, substantially as shown and described.
