                          Corner




                             By William Fischer


         Thank you as always, for your interest in Inventor’s
         Corner, and our publication. As we recover from a
         surprise April snowstorm here on the east coast,
         and spring is finally in the air, hopefully we can look
         forward to a burgeoning of industry along with
         the spring flowers. American industry has always
         been blessed with the most inventive and creative
         individuals, and it is our pleasure as always, to present to our readers, a smattering of the
         entrepreneurial spirit that we believe will lead our economy in the years ahead.

           An elevator installation with an elevator car and a counter-
         weight, a suspension cable suspending the elevator car and
         the counterweight, and a compensating cable compensating
         the effect of the weight of the suspension cable, is equipped
         with a compensating cable guide which for the purpose of
         guiding the compensating cable has at least one brush.
           Figures 1 and 2 each show an elevator installation accord-
         ing to the present invention. Shown in both drawings are an
         elevator car 1 and a counterweight 2 which are installed in
         an elevator hoistway 3. The elevator car 1 and the counter-
         weight 2 hang on a suspension means 4 via which they are
         moved vertically by a drive unit 5 having a traction sheave
         6 along guide rails which are not shown. Hanging between
         the elevator car 1 and the counterweight 2 respectively is
         a compensating means 7 in the form of a loop which is fas-
         tened by one of its ends to the elevator car 1 and fastened by
         an opposite end to the counterweight 2.
           Visible in figures 1 and 2 are two variants of a compensat-
         ing-means guide 8.1, 8.2. In each case, these have a number
         of brushes 12.1, 12.2 which guide the compensating means
         7 in the area of its reversal 7.1 perpendicular to the direc-
