Abstract: 277,600. Rhodes-Rochriem Manufacturing Co., (Assignees of Hochriem), G. F.). Sept. 14, 1926, [Convention date]. Printed records, apparatus for giving.-A weighing and ticket printing machine having a weighing mechanism including a printing member responsive to weight is provided with an impression member co-operating with the printing member, a continuous strip of tickets, mechanism for feeding the tickets into printing position with relation to the printing mechanism, ticket cutting mechanism, coin-controlled means for actuating the impression member and manually-controlled means for actuating the ticket cutting and ticket feeding mechanism and for restoring the impression member to its printing position out of contact with the printing member. In the operation of the machine the person desiring to be weighed steps upon the scale platform and a printing wheel is automatically rotated in proportion to the weight. When the weighing mechanism is stationary, as indicated by a pointer, a coin is dropped down a coin shoot thereby releasing a printing hammer to print the weight together with the month, day and year, upon the foremost ticket. An instant later a knife is raised and the printing hammer is withdrawn from contact with the ticket. A knob or handle in front of the machine is then pulled down and released causing (1) the strip of tickets to advance (2) the printing hammer to be raised to its uppermost position (3) an inked ribbon to be appropriately fed (4) the printed ticket to be cut off, and (5) the various tripping devices to be restored to their original positions. The usual scale platform is connected by a draw rod 12, Fig. 2, and by an intermediate lever to a weighing spring 29 and to a printing wheel 45 which, is rotated in proportion to the weight. Adjacent the printing wheel are three small printing wheels 46 - - 48, Fig. 44, adapted to be set by hand for the purpose of printing the month, day and year. A printing arrow is also arranged between the large and the small wheels to print an arrow on the ticket as shown in Fig. 36. The ticket strip is fed from a roll 66<1>, Fig. 2, by a spiked feed drum 68 and is guided over the lower portion of an endless inked ribbon 52 arranged adjacent the printing wheels. When the person on the platform drops a coin down the coin slot a spring- pressed lever 99 is liberated and raises a vertical rod 100. The rod knocks up a tripping catch 101 and thus liberates the printing hammer 84 which, assisted by a spring, falls upon foremost ticket of the strip and makes a printed record as shown in Fig. 36. The upward movements of the tripping catch 101 and of the rod 100 are momentarily checked during the descent of the printing hammer by a catch 106 which is however immediately released by a pin projecting from the hub 84<1> of the hammer. This delay in the rise of the rod 100 allows the printed record to be completed without interference from the knifeelevating mechanism which is subsequently liberated by the further upward movement of the rod 100. A dog 109 on the rod 100 now trips a lever 110 and allows a spring 114, Fig. 44, to actuate a bell crank lever 113 and by means of a slotted rod 116 to raise a knife 87 into engagement with a catch 143. The knife, in rising, feeds forward the inked ribbon 52 and also slightly raises the hammer from contact with the printed ticket. An external knob or handle 130 is now pulled down thus (1) actuating links 112, 125 to rotate the spiked feed drum 68 and feed forward the strip of tickets (2) pulling down a link 152 to raise the hammer to its original position, and (3) restoring the coin-controlled mechanisms to their original positions. The return movement of the knob is effected by a spring and during this movement a pin moving with the knob rocks a lever 147 thus drawing back a link 145 connected to the knife-supporting catch 143. The knife now descends under spring action and cuts off the ticket which falls down a discharge shoot to a ticket pocket at the front of the machine. A complete downward and return movement of the knob is ensured by an horizontal pawl 161 engaging teeth 160. A meter 168, Fig. 2, indicates the number of weighings and ticket-printing operations. The coin, after insertion in a slot 90 passes down a shoot 91 and strikes the end of a lever 93 thus displacing a catch 97 and freeing a spring-pressed lever 99 to bring about a printing operation. The lever 99 is restored to engagement with the catch 97 by the depression of the rod 100 when the operating knob 130 its moved downwards. After dropping a coin into the machine and thus causing the printing hammer to fall the coin slot 90 is closed until the hammer is again raised, by a plug 163 carried by a pivoted plate 164 connected by a link 166 to the hub of the hammer. If the roll of tickets 66<1>, Fig. 2, is exhausted an arm 174 bearing on the roll liberates a sprinpressed slide 176 which thereupon rocks the plate 164 and causes the plug 163 to close the coin slot.
