After describing the casing or receptacle in which the registering mech- anism and indicator are mounted, the specification states as follows: "The registering mechanism consists of two sets—a primary mechanism for temporarily registering the fares collected on each separate trip or direction of travel ofthe car or vehicle, and a secondary mechanism,·to which a trans- fer of the record of the primary register is made at the terminus of each di- _ rection of travel, to obtain a permanent record of the fares collected, the _ transfer being accomplished during the act of resetting or moving the pri- mary mechanism back to the zero or starting point, in readiness to commence. the registry of fares to be collected on the return or back trip of the car or vehicle. " . · . The specification then `proceeds to a detailed description of an primary register consisting of two disksor dials provided with figures. so con-, structed and arranged as to record and display the number of fares cor- responding with the number of actuations of the registering mechanism, through an aperture Owineow in the face of the receptacle, actuating mechanism, alarm apparatus, the secondary or permanent registering mechanism, suitable means for transferring the record made by thepri- mary registering mechanism to the permanent registering mechanism,. and an indicator or sign which is displayed through apertures in the face ` of the receptacle to visually denote to the passengers the direction of travel of the car or vehicle. The specification continues as follows: " To prevent the indicator being changed or shifted to indicate*a’ different direction of travel, without first making a permanent recordof the fares col- lected, and without moving the primary registry back to zero or the starting point, (beyond which point the registering disks cannot be carried, as the disk, B', will be locked by a paul, b', mounted on a stud or arbor, b", on the casing,) I provide the indicator-plate with notches, s, with which engage the tooth or projecting end of one arm, T, of a three-pronged latch, the latch be- ing provided in this instance upon the arbor of the ratchet-wheel that actue ’ atesthe bell-hammer, and is acted upon by a string which tends to keep the arm, T, normally in engagement with one of the notches, s. The other arms,. ~ T I T 2, of this three-pronged latch are adapted, when the register is at zero,, to vibrate the arm, T', into a notch, tl, in the unit disk, B, of the primary registe1· and the arm, T 2, into a similar notch, t2, in the disk,]3 1, of said reg· i ister. This will permit the indicator to be turned so as to bring the sign de- sired, indicating the direction of travel, opposite the window in the casing, the locking-arm,;'I‘, riding out of the notch, s, of the plate, and the other arms vibrating into the notches in the registering disks. When, however, an oper·. ation of the register takes place, the notches in the primary disks areptaken out of line with the prongs, T', T, of the three-pronged latch, which will effectually prevent the indicator—plate from being turned, as an attempt to turn the plate, except when the register is at zero; only brings the arms, T 1, T 2, in contact with the curved edges of the disks, which is not sufncient to carry the arm, T,. out of the locking-notch." The patentee closes the description of his invention in the specifica- tion as follows: "Ido not intend to limit myself to the precise construction and organiza· tion of the various parts of my improved register, they being susceptible of considerable variation without departing from the spirit of my invention., I V.33r.no.1--3
