Unused towel rolled up in a shell (4) is guided between a roller (38) and a tracer (40) for detecting the towel end and via a transport roller (6a), forms a loop and runs via a transport roller (6b) to a roller (13) guided in slots (14a,b) and intended for receiving used towel. To ascertain whether the loop is being used or not, there is a movement sensor (20) with a bar (22) which is suspended rotatably about a horizontal axis and to which is attached a batten (23) via which the towel (5) is guided. Clamped in the bar (22) is the upper end of a piezoelectric element which at its lower end is clamped between parts connected to a sensor housing (21). Since a distinction can be made between use and non-use, it is possible for released unused towel to be retracted again. Various programs can be selected for operating the towel dispenser, and in particular the loop can be formed from unused and used towel or only from unused towel.

Towel dispenser

Method for the sequential provision of portions of a towel web

The cloth towel dispenser appropriately comprises two towel units, whereof each unit is independently completely operational. The cloth towel (7) is guided over a delivery roller (20) into a draw-in roller (25). On pulling out the towel (7) for forming a towel loop (8), the delivery roller (20) is also rotated, as is the draw-in roller (25) via an envelope drive (32). In the draw-in shaft (30) is located a spring tension accumulator (36), which is tensioned on pulling out. By means of a cam wheel (43) and a catch (44), the length of the towel which can be pulled out is limited. As also a part of the used towel wound from the draw-in roller (25) can be retracted, the length of the clean towel to be pulled out can be kept smaller. After a certain interval a timer releases the catch (44), so that the spring tension accumulator rotates the draw-in roller (25) and the cloth loop (8) is wound up.

Cloth towel dispenser with two adjoining units

A cloth towel dispenser incorporates at least one towel unit. Each unit is provided with a first delivery station which supports a clean towel roll having a horizontal axis. The towel roll has a leading feed edge and is adapted to be freely unrolled in successive portions. The first station includes a delivery roller rotatable about a horizontal axis and disposed adjacent the roll for unrolling it. A second draw-in station is spaced below the first station and has a take-up roller freely rotatable about a horizontal axis. The second station includes a draw-in roller rotatable about a horizontal axis to retract the successive portions of the roll onto the take-up roller. The leading edge of the roll passes in a manually extractable loop from the first station to the second station along a path which extends downwardly from the first station to a position of use disposed below the second station and then extends upwardly to the second station. A drive arrangement includes gearing and a spring tension accumulator rotatably interconnecting the delivery roller and the draw-in roller whereby the delivery and draw-in rollers rotate in the same forward direction. The delivery roller, when rotating during and after the formation of the loop, rotates and tensions the accumulator.

Cloth towel dispenser and method for the operation thereof

In known textile towel dispensers the clean towel is manually pulled out at the front, the used towel is automatically drawn in at the rear, and the end of the towel hangs down vertically when the roll of clean toweling has been used up. The inventive towel retracting or retraction apparatus contains a towel loop loaded with a weighted roller and concealed by a cover which can be part of an enclosure. The used toweling or towel section is thereby pulled behind the cover where it can neither be seen nor reached by the user. A delay mechanism ensures that the towel loop, which is partially pulled out from the towel dispenser and partially pulled out from behind the cover, remains stationary for a few seconds before it is retracted behind the cover.

Method of, and apparatus for, retracting the loops and ends of towels

The room spray dispenser (1) holds a container (29) that is provided with a valve element (27) which also works simultaneously as a pump. Above the valve element (27) the operating end (25') of a pressure lever (25) is located. It is loaded in the direction of the valve element (27) with at least one spring (26,33). The blocking lever (14) has a raised contact surface (14'). This surface is pressed downward with the operating end (3') of a swivelling lever triggering mechanism, which is mounted on the door (5) or the door frame (6). This downward movement trips the blocking lever (14), which then allows the pressure lever (25) to press down upon the upper part of the valve element (27) due to the force of the tension spring (26). By the return movement of the swivelling lever (3) the blocking lever (14) is raised upwards to its original position and cocked by means of the cocking lever (15). The tension spring (26) is also stretched during this process. The advantage of this arrangement lies in its simple construction, positive operation, uniform dispensing of the mixture of deodorizing and/or scented liquid and air, and its general applicability to various kinds of door constructions or other elements which move relatively to each other. This arrangement requires no spray cans with propellent gas.

Room spray dispenser

The soap solution dispenser contains a reservoir into which opens an outlet or outflow opening of a container. In the reservoir there is present a float body or float which is pivotably mounted and provided with at least one indicator flag. Conjointly with the drop of the liquid level in the soap solution reservoir the float body also descends, which causes a displacement of the indicator flag. During the lowering of the surface of the soap solution the indicator flag moves along a viewing window formed in a cover or covering hood. There is thus signalled or indicated that the content of the soap solution in the reservoir is quite small or nearly consumed, so that the container now should be exchanged. One resulting advantage of the invention is that the indicator flag moves externally of the soap solution, so that the indicator flag cannot become stuck or bind, and thus, always remains readily visible.

Soap solution dispenser including indicator means for indicating the

An apparatus for forming and dispensing portions of soap foam or lather is provided with a double-acting compressed air membrane pump for generating compressed air and with a soap solution dosing pump. Both pumps are operated by means of a single lever which need only be pressed in a single direction, the return motion to the initial position being effected by a return spring. The forward actuation of the lever causes soap foam or lather to be formed in a mixing chamber. The return motion of the lever dispenses a dose of soap foam or lather through a dispensing aperture. In order to obtain a double-acting pump action of the membrane of the membrane pump, inlet valves and and outlet valves are employed. One of the outlet valves assists in the generation of the soap foam in the mixing chamber. The other outlet valve then assists in ejecting a portion of the soap foam through the dispensing aperture during the return motion of the lever.

Apparatus for forming portions of soap foam

An apparatus for forming lather or soap foam for washing and/or shaving purposes comprises an actuation lever which simultaneously serves to drive a piston, a liquid soap-dosing pump and a membrane pump for generating compressed air. A perforated wall of a conduit or line enables blowing the compressed air into a dosed quantity of liquid soap located within a mixing chamber, to thereby form a coarse bubble lather or soap foam which subsequently is blown through a porous body, homogenized and compacted. Different embodiments of the apparatus can be realized and it is particularly suitable for use as a foot actuated structure and for producing hot lather for shaving. A preferred construction contains an intermittently operated heater for preheating the compressed air, to thereby accomplish a particularly effective generation of hot lather. The apparatus has the advantage of increased economy owing to its reduced consumption of liquid soap and can be faultlessly hygienically operated and is especially environmentally protective.

Apparatus for dosing and forming soap foam

A soap solution dispenser for use in public and private lavatories, washrooms and so forth, has a refill cartridge for aqueous soap solution. This exchangeable refill or supply cartridge has a flexible connecting member mounted upon a hollow plug element of a solution level indicator. During use of the dispenser, first the cartridge is emptied, then the solution level indicator, and only then a reservoir within the dispenser. Thus, the contents of the cartridge can be used up completely, while the dispenser still remains operative because of the reservoir volume, until such time as the cartridge can be conveniently replaced. For higher contrast indication of the solution level, the indicator can contain an optical body or element which is immersed in the soap solution. The optical element only becomes totally internal reflecting when the refill cartridge is empty. Prisms can be provided so as to optimize the use of existing sources of light, and optical filters can be employed for an indication in color.
