Patented in the German Empire on June 22, 1907 .

The invention relates to a machine for washing and disinfecting hands by means of rotating roller brushes.

According to the invention, two roller brushes rotatable on parallel axes are of this type arranged that one brush against the other and press both brushes can rotate in the same sense.

The device is especially for doctors

ίο and nurses as well as for manual workers, in particular Lead workers, suitable, who * take special care to clean their hands have to.

An exemplary embodiment of the machine is shown in the drawing. Fig. 1 is a front view and FIG. 2 is a side view of the same. Fig. 3 shows an individual Part of the machine. '

The machine has two cylindrical brushes α and b, one of which is arranged in bearings of the machine frame c and the other is arranged on movable arms d, which in turn are attached to fixed arms c ^{1 of} the machine frame. The movable arms d are in their rest position on abutments, not shown in the drawing, which prevent the brush α from touching the other brush b. The arms d are provided with levers d ^l on which weights e are adjustably arranged in order to more or less compensate for the weight of the brush α. Rollers a ¹ and b ^{x are} attached to the axes of the brushes a and b , which are driven by drive belts α ^{4 and} i> ⁴ with two rolls 1 and 2 of a group of three connected rolls 1, 2, loosely arranged on the axis of rotation of the arms d. 3 are connected. The third roller 3 of this group is connected by a drive belt h ¹ to the pulley of a motor h , which starts the whole machine, i and k are two tubes with multiple holes along their length, which are connected to them by the two flexible tubes / ' Let the own line / supplied liquid flow onto the brushes. In this line ζ opens a Rohrw, which is connected to a container η containing a disinfecting liquid. Furthermore, a line 0 for warm water and such ρ for cold water are connected to the line I. The tubes m, ο and ρ are each provided with a tap, for the purpose of being able to regulate the composition and the temperature of the liquid flowing from the tubes i and k onto the brushes as required.

r and s (Fig. 2 and 3) are soap containers which are arranged parallel to the brushes α and b and are articulated by rods on sleeves / (Fig. 3) which sit loosely on the shaft carrying the arms d. On these sleeves, a sleeve is fastened by means of a clamping screw, which has an arm, at the free end of which a rod g ^{l is} articulated, which is connected at its lower end to a step g ^{1 lifted by a weight g · 3} . Due to the effect of the weight g ^z , the soap containers are kept away from the brushes in their rest position. If, on the other hand, the step g ^{2 is} pressed down, the rod g ^l also moves downwards

Claims (6)

(Fig. 3) and presses the soap container r and s against the brushes α and b, so that the bars of soap attached therein touch the brush. In order to collect the liquid dripping off the brushes, a trough t is attached below them, one edge t1 of which is designed in the form of a shield in order to prevent the liquid from splashing a person in front of the machine. For the same purpose there is a screen i2 above the brush α and a curtain t3 consisting of long bristles at the edge of the screen i2. To use the machine, the motor h is first started, whereby the brushes α and b are rotated in the direction indicated by arrows (FIG. 2). To clean the hands, the person concerned inserts them between the brushes so that the fingers get into the grooves. Since the brushes, as shown in FIG. 2, rotate in the same direction, the hands inserted between them are neither drawn in nor pushed outward. By stepping down the step g'2, the person washing himself can let the soap holders r and s touch the brushes and use the soap on them; hands can be rinsed and disinfected by adjusting the taps on lines m, ο and ρ. This disinfection takes place much faster and more thoroughly with the help of the brushes than without them. At their ends, the cylindrical brushes for washing and disinfecting the fingernails have bristles that are close to one another. Wide grooves a2, b'2 are provided on the brushes for washing the arms. In order to remove soap from hands and arms after using soap, there are also wide grooves a3, b3 on the brushes. To make the taps easier to use, they could also be moved using steps such as g2. The same step can be used to move the faucets and soap holders as well as a breaker controlling the motor circuit. Instead of using the soap in solid form, this could also be used as a solution which would be applied to the brushes through the tubes / or / 1 or similar devices. Instead of using weights, the brushes could also be moved relative to one another by springs or other devices. The counterweight gs could finally be replaced by a spring.
