BELL NIECHANISNI FOR EGISTEFZS.

Specicaton of Letters Patent.

Patented. Nov. '7, 1905.

Original application filed September 27, 1901, Serial No. 76,746. Divided and this application iiled April 23, 1908. Serial No. 153,904.

To cir/ZZ wto'm, t may concern:

Beit known that I, ARTHUR H.WooDwARD, a citizenot' the United States, residing at Chicago.v in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Bell Mechanism for Registers, of which the following is a specitication.

My invention relates to bell mechanisms for registers, and has for its object to provide a new and improved mechanism ot' this description.

My present application is a division ot' my prior application, tiled September 27, 1901, Serial No. 76,746.

My invention is illustrated in the accompanying drawings, wherein# s Figure 1 is a view of aregister embodying my invention with the face-plate removed. Fig. 2 is a sect-ion on line 2 2, Fig. l. Fig. 3 is a view of bell-operating mechanism. Fig. 4 is a view of the safety-dog located between the two bell-operating mechanisms. Fig. 5 is a side view of said dog apart from the mechanism. Fig. 6 is a view of Fig. 5 as seen from below. 7 is a view ot the bell-operating mechanism, showing the parts when the bell-hammer has been released. Fig. 8 is a view similar to Fig. 7 just prior to the release of the bell-liammer.

Like letters refer to like parts throughout the several figures.

I have illustrated my invention in connection with fare-registers adapted to registerv two classes of fares. rThe register mechanism proper is contained within the case A,

' provided with a suitable cover and adapted to be connected to a removable back. I/Vithin the case A are provided the two trip-registers and the two permanent registers. Two operating-levers F and G are pivotally connected to the register-case and ai'e provided with projecting pins or parts Y, which project beyond the register-case and which are actuated by the mechanism associated with the removable back. These operating-levers are connected with the mechanism of the register, so as to operate such mechanism when moved. As illustrated in the drawings, the

tripregister B and the permanent register D and associated partsform one mechanism tor registering one kind of fares and the trip-reg-A ister C and permanent register E and associated parts t'orm another mechanism for regof the mechanism associated with the back ot c the register either of these register mechanisms can be operated from any given point in the car.

As indicated in the drawings, the two tripregisters are arranged to indicate cash fares and transfers, although ot course it is evident that they could indicate any other kind ot' `fares desired. I provide two different bells having ditferenttonesone adapted to be rung when one class oi' fares is registered and the other adapted to be rung when the other class of fares is registered. In the construction illustrated in the drawings I place these bells outside of the register-case proper, providing an exterior chamber inclosed by the exterior bell-casing` O, attached to the main registercase by screws, which are inserted from the inside, so that they cannot be tampered with except by taking ott the top of the registercase.

The bells P and Q, as herein shown, are mounted one within the other to economize space, the inner bell Q being loosely mounted upon the supportR. The bell-hammers P/ and Q are located in the bell-casing and are provided with the hammer-arms P2 and Q2, which are contained within the casing and which may be integral with the bell-liammers or connected thereto in any other desired manner. These hammers are connected to the posts P3 and Q3 and may be integral with said posts or attached thereto in any desired manner. Mounted concentric with the hammer-arms are the hammer-levers P1L and Q", provided with notched ends, as shown in Figs. l and 3. These hammer-levers are connected by the connecting-rods P5 and Q5 to the operatinglevers F and G, as shown in Fig. 1. Pivotally connected with the hammer-levers are the hammer -dogs P and QG.` These dogs have a limited movement about their pivotal connection with the hammer levers, such movement being' obtained by the pins PT and Q7, attached to the hammer-levers, working in enlarged holes in the hammer-dogs. (See Fig.

Located between the two hammer-levers is a safety-dog S,adaptcd to cooperate with both of said levers and to engage the notches Sl in the face of the levers, so as to prevent them from beingl moved back before ringing the bell IOO after they have been started in motion. This safety -dog is illustrated in detail in Figs. 4, 5, and 6 and is pivotally connected to the base of the register-case and the holding-piece S2. The dog works about its center as a pivot and is connected to a controlling-spring S3 by means of a link S1. This spring besides controlling this dog has other functions and aids in the control of the hammer-dogs P6 Q15. lt will be noted that in this mechanism for ringing the two bells the mechanism is arranged so that a partial stroke of either is im possible, and yet there is used only three springs, the safety-dog springs S3 and the two bell-hammer springs Si.

Each of the hammer-dogs P2 Q11 has a series of working faces adapted to perform a separate function. The faces P2 Q8 engage the hammer-arms, so as to lift the hammers when the hammer-levers are moved. The inclined faces P'J Q1 engage the stationary parts or posts P10 Q10, so as to move the hammer-dogs to release the hammer-arms. The faces P11 Q11 engage the safety-dog and release it simultaneously with the release of the hammer-that is, simultaneously with the disengagement of the faces PS QS with the hammerarms P2 Q2. The faces P12 Q12 engage the stationary parts P12 Q11 when the dogs are moved back to their initial position and move said dogs from their released to their operative position-that is, the position where they engage the hammer-arms P2 Q2. Said dogs also have the projections or faces P11 Q11, which are engaged by the safety-dog as the hammer-dogs are moved forward, so as to insure the engagement of the hammer-dogs with the hammer-arms and prevent them from missing the hammer-arms due to jarring or the like during the first part of their forward movement. It will thus be seen that these hammer-dogs have no separate springs of their own, and yet perform a series of functions necessitating their being' held in different relative positions at different times.

It will be seen that in this construction there is a bell-hammer and a hammer-lever for operating the bell-hammer oscillating around the same center and a hammer-dog carried by the hammer-lever adapted to lift the bellhammer and release it at the end of the stroke, the release being a positive release at a predetermined point. There is also asafety-dog freely engaging the notched end of the hammer-lever when it is being moved forward, but which positively7 engages said level' if it is attempted to move it backward at any point between its initial and final positions. This safety-dog to be effective is released simultaneously with the ringing of the bell. This feature is necessary to the satisfactory operation of the device, for if the safety-dog is released an instant too soon the parts may be moved to their initial position without ringrelease of the safety-dog and the operator ceases moving the lever the mechanism does not return to its initial position. If, for example, it is desired to registera transfer fare, the operating-lever G is moved. The motion of the operating-lever G is communicated to the hammer-lever by the rod Q1, and said hammer-lever is moved forward. The hammer-dog Q, being attached to said lever, is moved forward and released from the post Q13. The projection or face Q1'1 is then engaged by the safety-dog S, so as to insure the engagement of the face Qs with the hammerarm Q2. The hammer-arm is then moved so as to move the bell-hammer away from the bell. As the parts approach the end of the stroke the beveled face Q" engages the stop Q10 and the hammer-dogis moved so as to release the arm Q2. The spring S2 then returns the bell-hammer and rings the bell. Simultaneously with this release and the ringing of the bell occurs the release of the safetydog. The parts are shown just prior to the release of the hammer-arm in Fig. 8. In Fig. 7 the parts are shown after the hammer-arm has been released and before the parts are returned to their initial position. When the bell has been rung, the handle is released by the operator and the spring in the back of the register moves the parts to their initial position.
