cross-bar d' fit the latter being mounted upon
a small shaft cV supported by its ends in a 55 frame or hanger cl' secured to the pipe h or to the frame or casing A. Upon this small shaft d` outside of the bar is secured a le-
ver consisting of a long arm K' and short arm K2. By this arrangement the valve c and 6o its stem will be left free to move endwise in-dependent of the lever K' K2 while at the same time by means of the ends of the cross-bar cl' fitting into the slots in the ends of the bar cl" the valve-stem will be oscillated 65 by the upward and downward movement of the lever to open and close the valve c'. This is a very important feature of my invention as it prevents the friction or weight of the lever from preventing the perfect seating 70 of the valve. Upon the end of the long arm K' of the lever is a small disk or trough e and upon the other or short arm is secured by a piston-rod g' a piston-head y' moving up and down with a cylinder M filled with wa- 75 ter or other liquid. The trough e when the long arm K' is raised upward as shown in Figs. 1 and 2 will come directly beneath the
inner end of a small chute leading from
the slot a' so that a coin dropped through 8o the slot will be carried by the chute into the trough e as hereinafter shown. The valve c will be so constructed that when the long arm K' is at its highest point the valve will be closed and will be wide open when the same S3 arm is at or near itslowest point and the ports b' b' will be so graduated as to size that enough liquid will pass through them to fill the vesselE while the lever K' K' is moving down-ward and upward again one full stroke within 90 a certain time as hereinafter explained. Small movable weights y' will be attached to the piston-rod g' to regulate the movement of the lever it being necessary to the proper action of the lever that the short arm K2 and its 95 attached parts should be heavier than the long arm K' when the trough e is empty while at the same time it must be so delicately poised that the weight of a small coin will overcome
the extra weight of the short arm and move ioo the long arm downward until the inclination of the trough will cause the coin to slide off.

Be it known that I WILLIAM HENRY 1 FRUEN a citizen of the United States and a 1 resident of Minneapolis in the county of Hen- 1 nepin in the State of Minnesota have invented certain new and useful Improvements in Automatic Liquid-Drawing Devices of which the following specification is a full clear and exact description reference being also had to the accompanying drawings in which
Figure 1 is a semi-sectional side view and Fig. 2 is a semi-sectional front view. Fig. 3 is an enlarged perspective view of the valve casing. Fig. 4 is an enlarged perspective view of the valve. Fig. 5 is an enlarged sectional side view and Fig. 6 is an enlarged plan view of the valve -casing and its actuating mechanism. Fig. 7 shows detached perspective views of the valve and its actuating mechanism. Fig. 8 is a sectional side view of a portion of the casing and reservoir illustrating the manner of arranging and constructing the automatic coin-chute-closing mechanism. Fig. 9 is a view of the coin-chute-closing slide.
A is an outer casing or frame made in the form of a building with the top or roof B adapted to be removed and with two recesses
C' C' in the form of "doorways" or "vestibules " formed in its front as shown. In the lower part of each of the vestibules steps D'
D' are arranged the step D' having a recess in its top to receive a drinking glass or cup E and the back part of the vestibule C' provided with a slot through which small coin may be passed as hereinafter shown. F is a tank or reservoir suspended in the upper part of the casing A and having a long tube G leading downward therefrom the latter supplied with a smaller tube H at right angles to it near its lower end.
h is a still smaller tube leading from the under side of the tube H out through the back of the vestibule C' and ending above the vessel E' as shown. The inner end of the tube H is provided with radiating ports b' adapted to be covered with a disk-valve c having corresponding ports b'. A valve-stem d' leads from the valve c through the center of the inner end of
the same. Upon the outer end of the valve-stem d' is secured a cross-bar J2 having slots
may be used in drawing nearly any kind of liquids.
The lever K' K2 may be adjusted by the small weights y' to adapt it to be operated by
5 any desired value of coin but usually adapted to be operated by one single cent. Being thus adjusted when a cent is dropped through the slot a' it will fall into the trough e and cause the lever K' to fall. The lever will fall until
io the inclination of the trough is sufficient to cause the cent to drop off and thus open the valve c and allow the liquid to run into the glass E. Then the short arm K2 being heavier without the cent. than the long arm will fall
15 again and close the valve.
In Figs. 8 and 9 is shown the mechanism for automatically closing the slot a' when the liquid in the reservoir is exhausted so that no coins can be passed through the slot except
20 when the reservoir is supplied with liquid. This mechanism consists of a float N resting in the liquid in the reservoir F and having a cord ' attached to it and passing up over a pulley on the top of the reservoir and down
25 outside the reservoir through an eye in one end of a small lever IF pivoted to the casing A and ending in a ball or enlargement as shown. The other end of the lever P is connected by a rod t to a slide R adapted to rise and fall be-
3o hind the slot a' to open or close it. The cord i' runs freely up and down through the eye on the lever IF when the float N rises and falls with the varying height of the liquid in the reservoir without affecting the lever except
35 when the liquid in the reservoir is so nearly exhausted as to' cause the float to fall so low as to raise the ball or enlargement i' far enough to strike the lever P and close the slide the lever P thus being actuated only when the liq-
40 uid is exhausted from the reservoir. By this means the coin-slide will be closed when the liquid is exhausted from the reservoir there-by avoiding the danger of the dropping of coins into the slot when no returns of liquid
45 can be had for it.
I do not wish to confine myself to this pre-
cise'method of connecting the float N and slide
or door B as I am aware that many simple
devices may be used for that purpose. The
50 piston gz rising and falling in the liquid in the
cylinder acts as a brake to the lever and
causes it to move slowly up and down and
thereby hold the valve c open much longer
than it would be held otherwise. By increas-
55 ing or decreasing the diameter of the piston-
head so as to leave a greater or less space be-
tween its edges and the sides of the cylinder
it will move with greater or less speed through
the liquid. The less space there is between
6o the piston-head and the cylinder the more
slowly will the piston-head pass through the liquid and vice versa. This is a very important feature of my invention as I am thereby enabled to very easily and perfectly regulate the flow of the liquid into the vessel E 65 as the more slowly the piston moves up and down the longer the valve c will be held open and the larger quantity of liquid be drawn from the reservoir F within a given time.
As before stated the mechanism will be so 70 adjusted that the vessel E will be filled while the lever K' K2 is making one full stroke or during the time the cent in the trough is moving the arm K downward and until the lever returns to its former position.
Another important feature of my invention 75
is the long tube G by which I am enabled to always secure a nearly uniform "head" of liquid above the valve c and thereby secure a more even flow than could be otherwise ob- 8o tained.
Having described my invention and set forth its merits what I claim is-
1. The combination of the reservoir F having the discharge-tubes G H and h valve c 85 lever K' K' pivoted to and adapted to open and close said valve trough e piston-rod y' piston-head g' and cylinder M substantially as and for the purpose set forth.
2. A easing A having recess C' adapted 90 to support a drinking-vessel recess C2 provided with coin-slot a' a reservoir for holding liquids discharge-tubes G H and h leading from said reservoir and provided with valve c and means substantially as described for 95 opening and closing said valve.
3. A reservoir for holding liquids a discharge-pipe leading from said reservoir and provided with a valve a lever adapted to open and close said valve means for moving said roo lever and a piston attached to said lever and moving in liquid simultaneously with said valve and lever substantially as and for the purpose set forth.
4. In an automatic liquid-drawing device 1o5 and in connection with the co-operative parts thereof the combination of a casing A provided with a coin-slot a' a reservoir F a float N within said reservoir a slide R and means for connecting said float with said slide r Io whereby the exhaustion of the liquid in said reservoir will cause said slide to cover and close said coin-slot substantially as set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. r r5
