Abstract: 23,797. Justice, P. M., [Lamson Consolidated Store Service Co.]. Oct. 28. Elevators. - Relates to apparatus whereby a load may be automatically transferred from a central or departmental despatching- station to a central or selected departmental receiving- station, the central stations being located in the ground floor of a building and the departmental stations at the several floors. The apparatus comprises a sectional cable B connected by hooks B' on frames D which carry rollers D' running on guide-rails A and from which are suspended comblike carriers C. At corners the cable is guided by rollers A', and the hooks B<2> are kept clear of the rollers A<7> by bars A<9> engaging rollers B<3> formed on the frames. Guide rails and rollers are also provided for steadying the carrier when passing the stations. The despatching-stations are arranged on the ascending run. The departmental despatching- stations comprise comb-like platforms F<1>, on which the load is placed and through which the carrier C passes in its ascent to receive the load. The platform F<1> runs on rollers F<2> and is normally retained in the retracted position shown in Fig. 9 by a weight F<3>. The load beirg placed upon the platform, a pivoted cam-plate H', Fig. 16, is moved by a handle H<2> so that a notch formed in it, corresponding to the receiving-station to which the load is to be despatched, is caught by a catch formed in a lever H<6>. A lever E is then moved into the position shown in full lines when a spring catch E<3> pivoted to it engages a pin integral with the platform, while a second pivoted spring catch E<5> locks the lever by engaging a fixed abutment. The carriers C are provided with pivoted levers C<3> which are depressed when the carrier is loaded so as to retract arms C<5>. When the lever E has been operated as above described, the projecting arm C' of the next ascending unladen carrier engages a tappet E<8> connected by a cord to the catch E<5>. The catch is thereby released and the lever E is moved by the spring E<2> into the position shown in dotted lines, carrying with it the platform F<1>. As the carrier detaches the load, the projecting arm C<5> is retracted so that the carrier does not operate on any succeeding despatching-platform, and a pin G<2> carried on a spring-controlled sliding rod G is moved by the cam-plate H<1> into a position corresponding to the floor to which the load is to be taken and is retained by a spring pawl G<3>. A pin P then releases the catch E<3> and the platform is drawn back by the weight F<3>, Also a roller on the carrier engages the lever H<6>, and the cam-plate H<1> is released and rotates to and is retained in the normal position. At the central despatching-platform on the ground floor, the lever mechanism is omitted. The departmental receiving-stations, Fig. 6, comprise pivoted comb-like platforms K' adapted to be thrown into the path of the descending carriers. As a carrier approaches the floor to which it has been despatched, the pin G<2> engages a correspondingly-positioned pin mounted on a shaft L<1> so as to rotate the shaft and remove a stop L from a rod K<7>, which then moves upwards under the action of a spring K<9> and carries with it a rod K<4> ; this rod is connected to an arm integral with the platform K<2>, which is then thrown outward so that the load may be deposited upon it. At the same time, an arm U' forming part of a system of levers S, V is moved into the path of the rollers D<2> of the carrier C. Accordingly, as the carrier passes away, the roller D<2> engages the lever U' and the platform K<2> is restored to the position shown in full lines, and the rod K7 is caught under the catch L. The main receiving-platform consists of a fixed comb.
