1 claim. (critter-tmf This invention relates to asurgeons 4soap dispenser andis designedas'an improvement over the construction shown in `applicants copending appl-itionlserial No. 51f0057, now Pate' No. 253,8"7;359,l The principal l Listo providea-highly efcient `cie'vioe of this harof Ithe us'r without it A"being necessary" for [the hands `or any Vother portion Yof the users body oniingincontact with the device orany part yA-neither object V`of theinv'ention is to {sojconstruct the 'device so that Aall of the exposed `parts will be smooth and rounded so that there will be no corners, pockets, or obstacles in which dirt or germs may collect.

A further object is to provide an electronicallyoperated soap dispenser in which all operating parts will be completely protected and yet will be readily accessible for replacement and repairs, and in which the soap container can be quickly and easily replaced or removed without disturbing the operating mechanism of the device.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and eiciency. These will become more apparent from the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views `of the drawing and throughout the description.

In the drawing:

Fig. 1 is a perspective View of the improved soap dispenser as it would appear in use.

Fig. 2 is enlarged longitudinal section therethrough.

Fig. 3 is a cross-section taken on the line 3-3, Fig. 2.

The improved dispenser is mounted on a backboard I0, and is completely enclosed within a water-proof cover Il. The cover is formed with an open back for receiving the backboard Il] and with an open bottom and is secured to the backboard IIJ by means of suitable angle clips I 2. The central portion of the housing is depressed as shown at I3 to form two side shoulders I4, between which is a depressed portion I3 provided with a perforated drain I5.

A soap pan I6 is positioned below the depressed portion I3 and is supported on two angle corner clips I'I secured to the backboard ID and extending beneath the two rear corners of the pan I6. The rear wall of the pan I6 is held against the ohjectfof the in en ion l i n lego; .A, r' les-imp in, pan IBupori a bracket arm 20. The braci garan .tQfthabaCkPOM-- mit Iubo me ns .of,.sx, szr, .t B faut 9, .a 3f. 3,# ,e .w are pump cyli r is through la suitable check valve 23. The tube 22 extends upwardly through the housing II, thence forwardly and downwardly to a position over the perforated drain I5.

A pump lpiston 24 is reciprocally mounted within the cylinder I9. The piston 24 is preferably of the cup-washer type-that is, when .it moves downwardly it spreads, to force soap into the tube 22, and when it moves upwardly it allows soap from the pan I6 to flow past the piston into the cylinder I 9.

The piston 24 is reciprocated from a piston rod 25 which is suspended from one extremity of a rocking lever 26. The rocking lever 26 is pivoted intermediate its extremities, as shown at 21, from suitable years on the bracket arm 20. The remaining extremity of the lever 26 is connected to an armature 2l of an electric so-lenoid 28 secured to the backboard I0. A tension spring 29 is stretched between the extremity of the lever 26 and a spring arm 30, secured to one of the clips I'I, so as to constantly urge the piston 24 upwardly in the cylinder I9. The piston is forced downwardly by the action of the solenoid 28 in attracting the armature 2'I.

The current supply to the solenoid is controlled by a photo-electric relay set 3| of any of the standard commercial types. Such a set contains a window which admits light to a photo-electric cell which is responsive to light changes. The set also contains suitable amplifying apparatus and a relay controlled thereby which in turn controis the current supply to the solenoid 28 through suitable conductors 32. The detail construction of the photo-electric set is not illustrated, since these are standard pieces of apparatus which may be purchased on the open market.

The set 3| is supported upon a suitable bracket from the backboard Il) in one of the side shoulders I4 so that its light-receiving window will` be positioned behind a transparent window 34 sealed in the housing II. A light-emitting opening covered by a suitable lens 35 is alsoy positioned in the inner wall of the opposite side shoulder I4 so that the window 34, the lens 35, and the discharge from the spout of the tube 22 will be in alignment with each other over the perforated drain I5.

An electric light source 36 is mounted in a receiving socket 31 on the backboard I0 with its filament in alignment with the opening 35 and the window 34. .This causes a, beam of light to be transmitted through the lens 35 into the window 34 to energize the photo-electric cell in the photo-electric set 3|, causing the relay therein.

they win interrupt the iight beam controlling Athe` set 3l, causing the latter to energize the solenoid- 28. This actuates the-pump piston 24 to discharge a predetermined quantity of soap yfrom the-cylinder I9 Vthrough the spout 22 onto the hands of the user. It can beV readily seen that the hands contact nothing butthe light beam when using the device. f f
