Fig. 2, pending from the same bar D at each end of shows the register case with one of the tablets the case is a hanger H; the hangers H support raised and with the money drawer open. Fig. three small rods 9, h, i, which extend across 3 is a front elevation of the register case a from one to the other, the rod h, being behind 3 5 part of the case being broken away to show the tablet rods, the rod i, being in front of the relative position of the tablet rods. Fig. them, and the rod 6, being beneath, the arm 4 shows in perspective and in detached form B of the key; these three rods all swing with a single tablet rod and key and those operatthe hangers H, and are swung by depressing ing parts of the register common to all the the arm 13,; the function of the rod e, is to 0 o rods and keys. swing the hangers II and to operate the lever A represents a case Within which are the F; the function of the rod h, is to hold the keys B, mounted on an arbor O, and extendlower end of the tablet rods R,when elevated, ing out through the walls of the case, and forward so as to keep the rack T, in mesh furnished on the outer end with numbered with the pinion t, and this rod will be called 5 45 fingered pieces 1; the inner end of the key B pressure rod 72,- the function of the rod'iis is turned upward, so that the entire key is in to push against the opposite side of the tabthe form of a bell crank lever, and the inner let rod and to force the lower end of the tabend is finished at its upper side in the form let rod backward,so as to throw the rack out of a Y, between whose arms, is the pinP proof engagement with the pinion, detach the I00 50 jecting from the side of the tablet rod R,; the tablet rod from the pinion and allow it to drop spread of the arms 19, p, is sufficient to prevent by gravity; this rod will be called hereinafter detaching rod tj inasmuch as both of these rods are fixed to the same hangers H they always move at the same time, and one moves out of operative contact with the tablet rod as the other moves into operative contact with it; both the pressure rod h and the detaching rod 1', are moved at the same time with the rod 6, whenever the end of the key B is depressed,inasmuch as this movement of the key B pushes the rod 6, downward and backward and swings the hanger H backward on the bar D. It also pushes downward one end of the lever F, and releases the double pawl Gfrom locking contact with the rack g. The lever F, is mounted on the case; the double pawl G,is mounted on the cover of the money drawer, and the rack g, is attached to the framework of the case, and is arranged to catch and hold either end of the double pawl G, that may be presented to it. The end of the lever F that is operated by the rod 8, is connected to that rod by a sliding joint, so that both the lever F and hanger H can move around their respective centers,while remaining in operative contact; the lower end of the tablet rod R,just above the fork, is of a width sufficienttonearly fill,the spacebetween pressure rod h and detaching rod i, and the rods 71, t, are so located with respect to the rod R, that when the rod R is pushed upward, and the hanger H is swung forward, as it will be by the rising of the rod R, the rod R, is held with considerable firmness in an upright position, with the teeth on the rack on the front side of the rod R, in contact with the teeth 25, on the pinion M, and the rack will remain in contact with the teeth t of the pinion M, and the tablet rod will be held in an elevated position after the bar E has been dropped back to the position shown in Fig. 1, but the depression of the end 1 of a key 13, throwing the hanger H backward and with the hanger H, the rod 2', forces the lower end of the tablet rod R, backward, and throws the rack T out of engagement with the teeth 25, and permits the tablet and rod, to drop by the force of gravity, to the position shown by dotted lines in Fig. 1; the swinging of the hanger forward is aided by the oblique under edge of the part against which the bar E comes in contact. Between the fork at the lower end of the rod R and the rack T, the stem of the rod R is narrowed so that when the tablet rod is down in the position indicated by the dotted lines in Fig. 1, the movement of the hangers II will not cause the detaching rod 6, to push against that part of the rod which is behind it, noron the other hand does the pressure bar It, act against that part of the rod which is then in front of it.
Above the rack T, is a bar N extending across the frame, and having a single tooth N or a rib on the side toward the pinion M, arranged to mesh in the pinion M; this barN is hung by a sliding joint to an arbor n, is
held forward into mesh by a spring a; the
space between the tooth on the forward side of the bar N, and the bottom edge of the bar N is equal to the pitch of the pinion M, or of the rack T and when the tablet rod is pushed upward so that the upper end of the rack T comes into contact with the lower side of the bar N, the tooth part of the bar N forms a continuation of the rack T, and causes the rack and pinion to intermesh accurately. The tablet rods are equal in number to the keys, while a single long pinion M, extending entirely across the case, receives motion from any one of the tablet rods, whenever that tablet rod is pushed upward.
The bar E extends across the case and is provided at either end with a cross head 6 movable vertically in ways or guides attached to the frame work; vertical motion is given to the bar E and the cross heads to which it is connected by means of a link or lever 5 hinged at one end by a pin 7 to the main frame work, and at the other end connected by a sliding joint to the cross-head 6.
The lever 5 is operated by the opening and closing of the money drawer in the following way; the money drawer is made in the form of a cylinder or part of a cylinder and turns on a journal or central arbor3; alink dhinged to the end of the money drawer eccentric to the journal 3 and reaching from the point of connection to the link or lever 5 is hinged to the lever 5; as the drawer is opened or closed by rotating it on the arbor 3, the lever 5 is lowered or raised and the cross head 6 carrying with it the bar E is moved downward or upward. On the end of the drawer is a double pawl G, and on the main case is a rack g, the pawl G engaging in the rack g, holds the drawer either in a closed position or in an open position or prevents itfrom being moved backward in either direction after the operator has commenced to move it either in opening or closing it. The pawl G is hung on a pin passing through its middle point and is held against the rack by a spring G; the side of the pawl next to the spring is fashioned in a double ogee curve; the two branches meeting at the middle point above [that is on the spring side] of the pin; the end of the spring is curved to fit the reverse curve or re-entering curve on either side of the meeting point just spoken of and the spring can be placed with this curved part pressing against either side of the meeting point of the double curve on the pawl, and when pressing on either side forces down the end of the pawl farthest from its point of pressure. A lever F is hinged to the case near the upper part of the travel of the pawl G, and when the drawer carrying the pawl is entirely closed, the end of the lever F rests against the end of the pawl G or a projection on the pawl G; the second end of the lever F is connected by a sliding joint to rod e, [see Fig. 2] and whenever the rod e is pushed downward by the key B, the end of the lever F is also pushed downward, and the end F is pushed upward against the pawl G, dis-engages the pawl at one end from the ratchet, forces the raised meeting part on the back of the pawl under the spring G and brings the opposite end of the pawl into engagement with the rack. It is evident that the drawer can be moved in a direction away from the holding end and toward the free end of the pawl, but that any attempt to move the drawer in the other direction will be prevented at once by the engagement between the pawl and the rack. A similar device at the opposite end of the travel of the pawl G,
is employed to throw the pawl over after the drawer has been opened and it is desired to close it.
It will be observed, that in a machine constructed according to my invention the movable parts are relatively few in number, and that most of the effective operations are brought about, by parts which act upon one or more tablet rods as may be desired; the principal object of the key is to set in position the tablet rod, and to operate the hanger H to release from the pinion t, tablet rods that have been previously thrown upward and caught upon that pinion; it will be further noticed that any tablet rod which is elevated, is in a position to be released by the movement of the rods 77., t', and that the rods h, 'i, are moved to release the tablet rod, Whenever the key lever is depressed. It will be further noticed that the form of the tablet rods is such that when they are dropped down and hang upon the rod D their lower ends are out of position to be caught and lifted by the lifting bar E, and that they normally hang in this position, and are only brought in position to be raised by the operation of the key proper to each individual tablet rod.
