MECiif-iNiSh/l FOR OPERATENG FARE REGISTERS.

.SEEGEFICATION forming part of Letters Patent No. 718,867, dated January 20, 1903. Application filed August 12, 1901. Serial No. 71,678. (No model) To all whom, it may concern:

Be it known that we, JOHN F. OHMER and HIRAM TYLER, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Mechanism for Operating Fare-Registers; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make an d use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to an operating device through the means of which fare-registors are operated and other adjunctive devices cooperating with said operating device, all as hereinafter more fully described and claimed.

Preceding a detail description of the invention reference is made to the accompanying drawings, of which- Figure 1 is an elevation of the mechanism for operating fare-registers with the present improvement applied thereto. Figs. 2 and 3 are detail elevations showing the mechanism comprised in the present invention cooperating wit-h the reciprocating member to compel a complete operation of the latter before returning to its normal position. Fig. 4C is an edge view of Figs. 2 and 3. Fig. 5 is an elevation similar to Fig. 1, showing some modifications in the mechanism controlling the reciprocating member. Figs. 6, 7, 8 are detail views of the controlling mechanism shown in Fig. 5. Fig. 9 is a detail of the dog cooperating with the mechanism shown on Sheet 2.

In a detail description of our invention similar reference-fign res indicate corresponding parts.

1 designates a casing which is attachable to the rear of a fare-register, as illustrated in the patent hereinbefore referred to. WVithin this casing is mounted the mechanism by which the mechanism of the fare-register is operated. This mechanism consists of a reciprocating member or slide 2, which has integral end guide- pieces 3 and 1, that move on tracks or guide-strips 5 5, suitably secured to the casing 1.

The said reciprocating member has an upwardly extended portion 6, which terminates in a head 7.

8 8 designate two bell-crank levers, which are fulcrumed at 9 9 to the rear of the casing 1 in any suitable manner. The lower arms of these levers lie in positions below the head 7, and as said levers are actuated by the ropes or cables 10, which are connected to their upper ends, the said. reciprocating member 2 is elevated to operate the mechanism of the register, and as said ropes 10 are released the said bell-crank levers are permitted to drop to their lower positions under the influence of springs 11, thus permitting the reciprocatin g member to drop by gravity to its normal position, as shown in Figs. 1 and 5. This describes briefly the mechanism for operating a fare-register as disclosed in the patent hereinbefore referred to.

Referring to the present invention, one end 4 of the reciprocating member 2 is provided with a series of ratchet-teeth 12, above and below which are recesses 13.

14 designates a dog which is pivoted to shown in Fig. 1 the dog 14 is caused to assume an upwardly-pointing position by the upper surface 16 coming in contact therewith. In this position of the dog it enters the ratchetteeth 12, as shown in Fig. 3, as said member 2 is being moved upwardly, and the said dog freely rides in and out of said teeth during such movement; but in the event thatacomplete stroke or upward movement of said member is not made the said dog will engage the teeth, as shown in Fig. 3, and prevent a return movement of said member 2 until the complete elevation thereof has been made. The same conditions take place upon the lowering of the said reciprocating member 2. After said member has been moved to its upper limit the dog 14: enters the lower recess 13 and occupies a position similar to'that which it is shown to occupy in the upper recess 13, Fig. 1. Upon the lowering of said member 2 the lower surface 16 engages with the dog 14 the tension of spring 20.

normally in by a coil-spring 20.

and causes it to point downwardly or reverse its position, as shown in Fig. 2. The dog in such position rides freely over the ratchetteeth 12, permitting the slide or member 2 to drop to its lower or normal position, as in Fig. 1, after which the said dog again assumes a straight position in the upper recess 13.

Referring to the modifications shown on Sheet 2, the end of the reciprocating member 2 is devoid of the ratchet-teeth 12, as shown in Fig. 1. 1'7isataperinglugprojectingfrom one end of said member 2. 18 is a depending pawl pivoted at 19 to said member 2 and held In this position a projection 21 on the lower end of said depending pawl engages with the lug 1'7 and prevents the spring 20 from drawing said pawl too far inwardly. A similar projection 22 on the lower end of said depending pawl engages with the inner side of said lug 17 and prevents said pawl from moving too far outwardly under the control of dog 23, which will again be referred to. The depending pawl 18 has two sets of ratchet- teeth 24 and 25, which project in opposite directions,or one set of whichnamely, 2atprojects downwardly, while the outerset 25 projects upwardly. The dog 23 is pivoted to the guide-strip 5 at 26 and is pressed inwardly by a spring 27.

As shown in Fig. 9, the head 23 of said dog is provided with two engaging surfaces 28 and 29. Surface 28 engages with teeth 24 in the elevation of the member 2 and compels a completion of each operation of elevating said member. During the operation of elevating said member the surface 29 rides against the inner or straight side of the teeth 25, as shown in Fig. 5. When the operation of elevating said member is completed, as shown in Fig. 7, the inner side of the head of the dog 23 comes in contact with the upper tapering surface of the lug 17 and moves the depending pawl 18 outwardly a sufficient extent to allow the engaging surface 29 on said dog to assume an outer position, as shown in Fig. 7, after which said depending pawl assumes its normal or straight position, as shown in Fig. 8, under In this position,Fig.

8, the outer engaging surface 28 of said dog is entirely away from the ratchet-teeth 24, and the engaging surface 29 of said dog rides in the teeth 25 and prevents the member 2 from being elevated before it has reached its extreme lower or normal position. In other words, the engaging surface 28,- cooperating with the teeth 24, prevents the sliding member 2 from being lowered at any time during the upward movement thereof and until it has assumed its complete upper position, and then, as before stated, the dog 23 moves the depending pawl outwardly, as in Fig. 7, and thereby the engaging surface 29 is enabled to come into operative relation with the ratchetteeth 25, which controls the member 2 against upward movement while it is in the act of being lowered.

Having described our invention, we claim- In mechanism for operating fare-registers, a sliding member having vertical side extensions 3 and 4 movable on vertical stationary tracks 5 5, one of said side extensions being provided with ratchet-teeth, recesses above and below said ratchet-teeth, the outer walls of said recesses terminating in tapering surfaces, an upper extension 6 projecting from the center of said sliding member and terminating in a head 7, bell-crank levers engaging said head from opposite sides and by means of which the sliding member is actuated for the purposes specified, a reversible ratchet-pawl pivoted to one of the tracks 5 and engaging the ratchet-teeth on the extension 4, a spring attached to said ratchet-pawl and to one of the tracks 5, the said spring and the tapering surfaces of the recesses above and below the ratchet-teeth combining to change the position of the ratchet-pawl when the latter is out of engagement with said ratchet-teeth, substantially as set forth.

In testimony whereof we affix our signatures in presence of two signatures.
