SOAP-DISPENSING DEVICE.

To all whom it may concern:

Be it known that I, EVERETT F. TAWNEY, a citizen of the United States, residing at Winona, in the county of Winona and State of Minnesotarhave invented new and useful Improvements in Soap-Dispensing Devices, of which the following is a specification.

This invention relates to soap dispensers, and it has particular reference to a device for dispensing so-called soft soap as distinguished from liquid soap, the latter being in the nature of an easy runnin fluid, while soft soap is of viscous or ge atinous substance.

The principal object of the invention is to produce a device ofsimple and improved con struction whereby a predetermined charge may be delivered at each operation.

With this and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the dra\ving,I igure 1. is a vertical sectional view partly in elevation of a dis pensing device constructed in accordance with the invention, and showing the operating parts in normal or initial position. Fig. 2 is a sectional detail view showing the operating parts in discharging position. Fig. 3 is a sectional view partly-in elevation of the iston or plunger which constitutes a part 0 the invention.

Corresponding parts in the several figures are denoted by like characters of reference.

A cylinder 15 is provided intermediate its ends with an obstructing head or closure 16, said cylinder having also at its inner end a supporting flange 17, whereby it may be attached to the wall of a lavatory or in some other convenient position. The front end of the cylinder is provided with a cap 18 which is threaded thereon and which is axially apertured for the passage of a stem 19 carrying a piston P, said stem being also pro- Specification of Letters Patent.

thumb piece 20. The piston P is provided intermediate its ends with an annular recess 21, the reduced portion formed by said recess being provided with a transverse aperture 22. The inner end of the piston has a recess or socket 23 which communicates with the transverse aperture 22 through a bore 24. A spring 25 situated in the socket 23 abuts on the closure 16 and serves to project the piston in an outward direction. The outer'portion of the piston is bisected transversely to form two parts or

members

26, 27 which are connected together by a threadedstem 28 and between which there is interposed one or more packing washers 29. The stem 28 is engaged with the outer end of the bore 24 which is threaded for the reception of said stem, and the outer end of which is thereby obstructed.

The cylinder 15 supports a hopper or container 30 which has been shown as being provided with a nipple 31 that is threaded into the upper portion of the wall of the cylinder. The cylinder is also provided with a downwardly extending discharge nipple 32, the latter being out of alinement with the nipple 31, said discharge nipple being postioned relatively near the outer end of the cylinder.

It will be observed that the washer 29 will snugly engage the inner wall of the cylinder, constituting a packing member whereby, when the piston moves in an outward direction, suction is set up in the rearward end of the cylinder, creating a partial vacuum whereby a portion of the viscous or pasty soap substance placed in the container 30 will be positively sucked or drawn through the nipple 31 which constitutes the inlet port into the cylinder. It will also be observed that the partsare so proportioned that when the piston is forced inward against the tension of the spring 23 to the limit of its movement, it will practically abut on the member 16 which constitutes the inner end or head of the cylinder, while when the piston moves outward under the tension of the spring, its inner end portion will partly overlap the inlet port formed by the nipple 31, the extent of the overlap being governed by the number or the thick ness of the washers 29. It follows that when the piston is forced outward, the amount of soap entering the cylinder to the rearward pared for use in connection with this device is of such pasty consistency that while amenable to the action of the suction device,

it will not of itself flow or gravitate through the port 31. It will also be seen that the extent of the charge is not governed by the length of the stroke of the piston, said stroke being limited by the piston member 27 in one direction and by the button 20 in the other direction. When the piston is projected outwardly, the bore 24, the space formed by the annular recess 21, the trans- .verse aperture 22 and the socket 23 will be filled with soap, while the space of the cylinder to the rearward of the piston will contain only the relatively small quantity of soap required to form a single charge which has been sucked or withdrawn from the container through the port 31 by the forward movement of the piston.

\Vhen the parts are assembled, as shown in Fig. 1, and the cylinder is projected to its full extent in an outward direction by the action of the spring 25, the outlet nipple 32 will be obstructed, but communication will be establishe d between the cylinder 15 and the container 30 through the port formed by the nipple 31. By each operation of the piston or plunger (each operation being taken to mean the pushing inward of the piston against the tension of the spring and its subsequent projection in an outward direction by the action of the spring) will cause a portion of the contents of the hopper 30 to be drawn partly by gravity and partly by the suction created by the plunger into the cylinder. After the operation has been repeated a few times the recess or socket 23, as well as the bore 2-1, the transverse aperture 22 and the annular space 21 will become filled with the soft soap and a charge of soap will be contained in the cylinder to the rearward of the plunger, so that by the next inward movement of the plunger against the tension of the spring,

the inlet port being obstructed by the inner portion of the piston, a portion of the soap contained in the socket23, bore 24, perforation 22 and recess 21 will be projected through the nipple 32 with whichthe annular recess 21 will be in registry when'the piston or plunger is moved in an inward direction. By the subsequent outward movement of the plunger under the tension of the spring the next charge is drawn into the cylinder to the rearward of the plunger.

It will be seen from the foregoing description that I have produced a soap dispensing device adapted peculiarly for dispensing soft or viscous soap, a predetermined charge at each operation, and in which the working parts are simple and not liable to get out of working order. The soap in itself constitutes a lubricant whereby the parts are maintained in good working condition.

Having thus described the invention, what is claimed as new, is

1. In a device of the class described, a cylinder having non-registering inlet and outlet ports, a hollow piston having an annular reduced portion and a transverse passage establishing continuous communication between the reduced portionof the piston and the cylinder, and a spring seated within the piston to normally project the latter, said piston having means tive length for the purpose of varying the area of the inlet port, as set forth.

2. In a device of the class described, a cylinder having min-registering inlet and \outlet ports, a hollow piston having an annular reduced portion and a transverse passage establishing continuous communication between the reduced portion of the piston and the cylinder, and a spring seated within the piston to normally project the latter; the inlet port being partly overlapped by the piston when the latter is in-normally projected position, said piston being pro- .vided with means whereby "the amount of the overlap may be varied.

'3. In a' device of the class described, a cylinder having non-registering inlet and outlet ports, a hollow piston having an annular reduced portion and a transverse passage establishing continuous communication between the reduced portion of the piston and the cylinder, and a spring'seated within the piston to normally project the latter; the inlet port being partly overlapped by the piston when the latter is in normally projected position, said piston being provided with detachable washers, whereby the amount of the overlap may be varied by varying. the thickness of the washer, said washer operating to create a suction upon the return stroke of the piston.

In testimony whereof I afiix my signature in presence of two witnesses.

EVERETT TAWNEY.
