Abstract: 20,788. Feeny, V. F., [Holden, A. P., and Copeland, R. J.]. Sept. 15. Cleaners for tobacco pipcs.-In a coin-freed apparatus for cleaning tobacco pipes, an aircompressor is set in motion by the operation of the coin mechanism after prepayment and is automatically stopped when the compressed air (which may be contained in a storage tank) has attained a predetermined pressure. After prepayment, the operator rocks a hand-lever y, Fig. 4, which, by means of a hinged arm b<11> thrusts a spring- controlled rod a<11> to the right, thereby throwing the contact arm v<1> of a rocking switch v into engagement with the contact blades z<1> and closing the circuit of an electro-motor d<11>, Fig. 2, the rocking switch being maintained in this position by the engagement of a detent y'. The hand-lever y simultaneously moves forward a coin-carriage c, Fig. 5, which is solid with lateral plates v<3>, the carriage being retained in the extreme position by the engagement of the nose w of a lever t with a projection x on the framework, Fig. 4. The motor d<11>, Fig. 2, drives an air compressor h<3>,which forces air into a tank j<11> connected by a duct m<1> to a valve chamber k<1>, Fig. 5, having an open port q<1> communicating with a hollow flexible blade s<1>. When the air has attained a certain pressure (indicated by a gauge j<6>), the blade s<1> engages an adjustable screw t<1> on the arm u<1> of the rocking switch, turns the switch about its pivot, and opens the motor circuit. During the forward movement of the coin carriage a rack r<5>, Figs. 4 and 5, on one of the lateral plates v<3> rotates delivery rollers g through ratchet gear h, j, thereby feeding forward a length of paper from a storage roll. The operator next inserts the nozzle r<6>, Fig. 2, of a flexible tube r<5> into the bowl of the pipe, wraps the piece of paper around the pipe stem, inserts the mouthpiece into a nicotine carriage k, Fig. 8, and moves the carriage inwardly. This movement of the carriage effects the opening of the supply valve j<1>, Fig. 5, permitting the compressed air to pass by a duct r<1> to the flexible tube r<5> and thence into the pipe, forcing the nicotine through the paper surrounding the stem into a removable vessel k<4> , Fig. 8. The valve j<1> is opened (a coin being in position on a stop g<1> in a shoot d) by the movement of a sliding rod h<1> to which is attached a pivoted lever k<9> adjustably connected to the nicotine carriage by screws o<9>, Fig. 8. An arm k<8>, Fig. 5, on the rod h<1> simultaneously trips the lever t from engagement with the projection x permitting a spring r to return the coin carriage. A spring-controller lever (not shown) engages a collar i<5> on the valve-rod and retains the valve in the open position, the lever being tripped by a member on the rod h<1> during the return movement of the nicotine carriage. To ensure the complete opening of the delivery valve the nicotine carriage is provided with a yielding arm l<9>, Fig. 8, which must be forced past a projection l<7> fixed to the casing.
