Specification of Letters Patent. Pateilted sept. 29, 1914:.
- Application filed June 19, 1912. Serial No. 704,662.
Majesty the King of Great Britaimresiding' at Imperial Buildings, 3 Dowling street, Dunedin, in the British Dominion of New Zealand, have invented certain new and useful Improvements in Automatic Electrical Announcers, and do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i
This invention hasreference to route in dicating apparatus, and it comprehends, briefly, certain hereinafter described improvements in or relating to the mechanisms for effecting the requisite movements of the indicator proper, for stopping and reversing such movements, and for announcing each alteration in thesaid indicator con sequent upon its movements.
An embodiment of the invention is indicated in the accompanying drawing, whereof I Figure 1 is a front elevation of the apparatus, with the cover of the casing, wherein it is disposed, removed Fig. 2 is a transverse section taken on line AB, Fig. 1; Fig. 3 is a plan view of Fig. 1;Fig. 4 and a are respectively, a plan view of one of the winding rollers, and a detail sectional view of one of the bearings for said roller; Fig. 5 is a transverse section taken on line C-D, Fig. 1; Fig. 6 is a diagrammatic view of the wiring of the apparatus; Fig. 7 is a diagrammatic view of the wiring of the annunciator; Figs. 8 and 9 are side elevations showing two positions assumed by the armature included in the electro magnetic reversing mechanism; Fig. 10 is a perspective view of the apparatus, Fig. 11 is a fragmental front elevation of a modilied form of the invention; Fig. 12 is a transverse section taken on line EF, Fig. 11; Fig. 13 is a plan view of the armature shown in Figs. 11 and 12; and Fig. 11 is a diagrammatic view of the wiring for the aforesaid modification.
For the purpose of indicating the stopping places, there is employed a band 1, as in other inventions of the sameclass, and this band may be made of any thin, flexible material, and may have holes 2 punched therein, adjacent to one edge and at equal distances apart, to receive the studs 3 affixed to the central roller 4, whereby motion is imparted by the band to the roller, regularity in the travel of the band is insured, and puckering of the hand is prevented.
Said band is mounted upon winding rollers 5 and 6. Each of the rollers 5 and 6 may be provided at one end, for convenience of mounting, with a movable spring bearing, such bearing consisting, in the construction illustrated, of'a cap 8, and a plunger 7 whose stem works in saidrcap and is encircled by a spring 9 that bears against a flange 10 on saidstem. The end ofeachplunger is thus held in engagement with the end of the corresponding roller 5m- 6, to assist in supporting the same and in preventing spinning when thecurrent is cut oil. The said rollers 5 and 6 are preferably demountable, so as to facilitate the changing of the band to suit different routes, and to accomplish this, they are provided at the opposite ends from those engaged by the plungers 7 with tongues 5 and 6 designed .to fit in slots formed In the corresponding bearings 5 and 6 these tongues are provided, in turn,
with small lugs 5 andG which project therefrom intosaid hearings, to center the rollers with respect to. the driving gear; When the plungers 7 are forced inwardlyof their caps, againstthetension of springs 9, the opposite ends of the rollers 5 and 6 are released, whereupon the band may be lifted clear of the apparatus.
The apparatus necessary to effect the movementbf the band comprises, briefly, a battery 11 to supply the electric current, conducting wires 12, a circuit closer or closers 13,-and a motor 11 to actuatethe roller mechanism. The automatic stop apparatus, Fig. 2, consists of a pair of electromagnets 15, a platinum-pointedcontact screw 16, a pivoted armature 18, and awire 17,-the saidlwire being connected to the magnets and forming a circuit with the motor through the said screw to said armature'by means of a spring 19 attached to the armature. In the construction shown, the armature is in the form of a lever pivotally mounted at one end and pro vided at its other end with an insulated detent'QO, which latter is designed to en- I The circuit closers 13 may be simple push-buttons, and when one of them is actuated, the magnets 15 attract armature 18, thus releasing detent from engagement in seat 23 in roller 4 and making a contact with screw 16, which simultaneously completes the motor circuit. The closing of the latter circuit actuates the roller 5 or 6, and transmits motion to band 1 and to roller 4. On releasing the push-button, the current is cut off from the electro-magnets 15, and the armature 18 is pulled back, under the influence of an adjustable tension spring 22, into position to engage its detent20 in the other seat 23 in roller 4, which latter continues to revolve until that seat is opposite saiddetent. Further movement is prevented by the disengagement of spring 19 from screw 16, which breaks the motor circuit until the button is again pressed. The resistance of the magnets 15 mut be slightly greater than that of the reversing magnets 24, Fig. 5, which latter attract the pivoted armature 46, so that when once the connection is made by armature 18, the greater part of the current is shuntedth-rough the reversing magnets, thereby immediately energizing them, sufficient magnetism being retained in the mag- I as nets 15tohold armature 18 in position until released.
In the modified construction shown in Figs- 11 and-12, the indicating band 1 travels over a'pair of guide rollers 5 and 6 and is connected at its ends to a pair of winding rollers: 5 and 6 the rollers 5 and 5 being located at the top of the ease wherein the. apparatus is disposed, and the rollers 6 and 6 at the bottom of such case. During its passage between the two guide rollers, the band crosses a small metal .plate 25 having an aperture 26 therein, with which aperture a series of equally spaced apertures 2 in said band successively register. In this form of the invention, the armature lever 18, which coacts with the magnets15, has one end 27 extended laterally and provided with a roller 28, the other end 290i said armature being connected toa tension sping 22, so that when the magnets are deenergized, the said spring will force roller 28 through one of the apertures 2 into the aperture 26. This movement of said roller is suflicient to release spring 19 from contact with screw 16 and thusabreak the motor circuit, whereupon the band is instantly stopped and is retained in position by the engagement of the roller teration in the indicator by means of a suitable circuit closer 83, here shown as constituted by a spring whose free end projects into the path of a cam 32 on the adjacent end of roller at. When said spring is engaged by said cam, it will be pressed against a contact 33, thus completing the circuit. In the modified construction, the circuit closer is constituted by a contact finger 33 which is connected to the end 29 of the armature lever 18 (Figs. 12 and 14:), and is moved, consequent upon the attraction of said armature, into contact with a finger 33 included in the bell circuit. Means is provided for reversing the direction of travel of the band, such means being common to both forms and consisting, by pref erence, of a gear t 'ain, (Fig. 5), comprising a pair of gears -13 and ll: secured, respectively, to the winding rollers 5 and 6, (or 5 and 5), a gear fast on a spindle 47 carried by the armature 16 of the reversing magnets 24., and a second gear 48 also fast on said spindle and meshing with a driving gear 4-9, (Fig. 1), on the motor shaft 50. Armature 46 is normally held in neutral position through the agency of springs L6 which engage an extension 11-6 on said armature. The gear 45 is designed to mesh alternately with the gears 4:3 and 44-, consequent upon the rocking of armature l6, as will be understood, while the gear 48 is constantly in mesh with the driving gear 49. To control the reversing gearing, a suitable switch 51, attached to the case, may be employed. The hell, or other amiunciator 30, may also be mounted upon said case, as represented in Fig. 10.
The operation of the appa'atus is believed to be apparent from the foregoing, and, hence, to require no separate explanation.
