LEO LEON SIMPSON, OF SEATTLE, WASHINGTON.

ANNUNCIATOR.

Specicaton of Letters Patent. Patented Sept. 17,1912.

Application led June 19, 1911. Serial No. 634,658.

To all whom 'it may concern Be it known that I, Luo LEON SIMPSON, a citizen of the United States,and a resident of Seattle, in the count-y of King and State of VVashingtcn, have invented a certain new and useful Improvement in Annunciators, of which the following is a specification.

The principal object of this invention is to provide an improved annunciator especially adapted for use in street cars, coaches and thelile which is operated by combined mechanical and electrical means-,and at all times under complete control of the driver. The invention will be fully described in the following specification and shown in the accompanying drawings-in which,

Figure 1 is a side elevationof the device with parts broken away; the parts broke-n away being identical with those shown. Fig. Y2 a plan view with parts broken away. Fig. 3 an endelevation. Fig. 4; a fragmentary View of an ordinary street car showing the manner of applying my device thereto. Fig. 5 a plan view of the-switchboard. l

Referring now more particularly to the drawings, 1 is a'nietal sheet bent at right angles, as shown in Fig. 1. 2 designates ,the side coverings of similar sheets, and having the ears- 3 bent over the edgesof the sheet 1 (Fig. 3) and secured thereto by the screws '4. This box like structure may be suspended for instance, ateither end ofthe car by means ofthe'hangers 5, and constitutes the lou'sing for the working mechanism which I will now describe. v

6 designates' a series of levers pivoted upon the rod 7 which runs through l.the loop .or eye 8 formed at the upper edge of thev sheet 1, and upon the free ends of which levers are the weights 9. To the inner end of each lof these levers is pivotally attached one end of the link 10, to the other end of this link is similarly attached the ear 11 of the card 12, 'which may be of ordinary paste-board reinforced with the metal. strip 13. The bottom of the housing is cut away directly beneath these cards 12 so that the same may drop therethrough when ree quired, as will be explained; `Parallel with the horizontal. portion ofthe sheet 1 is a similar sheet 14, passing through both' of which sheets are the binding posts 15 which are reduced andthreaded at their ends to receive-the nuts 16. Between the sheet 14 and the horizontal portion of the sheet l are the electromagnets 17. vSuspended from the levers 6, by means of the links 18, arel the metallic plungers 19. The magnets 17 are connected with the battery 2O by the wires 21.

22 is the switch-board, hav-ing the arm 23 pivoted .at- 24 so that the arm may be swung into any one of the divisions A, B, C, I), E, F, G, to .close the electrical circuit, as will be understood.

It will be appreciated that economy of space is of great importance in the use of this class of annunciators and that `such economy results from the use of my improved construct-ion, the working levers, magnets and their connections being ar .ranged side by side, and if necessary can be closed up together almost entirely, 'the spaces between the. magnets being separated only by a thin sheet of .card board or other insulating material sucht as indicated by the reference numeral 19a (Fig. 2).

From the foregoing it is believedA that the construction and operation of my device will be fully understood by those skilled in the art. l I

When the arm 23 is in the position shown in Fig. 5 the circuit is broken and the magnets 17 denergized, which causes the levers 6 to swing about their pivots 7, the weighted ends 9 descending by gravity and their ,opposite ends ascending carrying Vwith them the plungers 1.9 and their attached cards 12 which latterv are then obscured by the sides 2. Now, supposing that the deviceis attached to an ordinary street car, for exam- .ple, an occupant of the car such as the mo-l torman, upon the car reaching an intersecting street D swings the arm 23 around to the corresponding division D upon 'the switchboard 22, as shown in dotted lilies- (Fig. 5), thufsclosing the electrical circuit from the battery 20 thereby energizing the magnet- 17 which through -its connections controls the card 12niarked I) This enswitchboard to which..the arm 23 haspre' viously been moved. Thepartsare now in' their dotted positions thecard 12 marked as shown m Flg. il.,

D being exposed to view Hbelow the'bottom of the ^hgrizontal porti-on of the sheet l. After holding' the arm 23 in its dotted position for a suitable interval of time the same may then be re turned to its normal position, which causes all the magnets 17 to be denergized and the resultant return of the cards to their normal positions behind the sides2, until the na'me of the next street is desired to be announced when the operation just described is repeated.

I have shown but a limited number of cards' 12 but it is obvious that any desired number may be used With equal efiiciency,

vwithin reasonable limits, and while I have shown my device as applied to a street car it is'clear that the same may be successfully applied to many other analogous uses.

Many other changes as to construction and detail will readily suggest themselves to others skilled'in the art, without departing from the spirit and scope of my invention, and I do not, therefore, .desire to be limited to the exact form of construction herein shown and described except as set 25. lforth in the appended claims.

What I claim as new and desire to protect by Let-ters Patent of. the United States, is 1. The combination in an annunciator of housing and rods extending along two of its sides, levers pivoted upon said rods and 'arranged '1n oppositely disposed pairs, the

inner ends of the levers upon one ofrv the rods being inspaced relation-to the inner ends of the leversvuponthe other rod and all thelevers having their outer ends weighted;

display cards, the length of each of which substantially equals the space between the inner ends of each pair of levers; means for attaching one of said'cards between the i n Y levers at a time.

2. The combination inan annunciator of a housing having its bottom'formed of a' sheet of metal and two of its sides,- formed by upwardly bending each end of said sheet, eyes formed by rolling the upperedges of said sheet, rods extending through said eyes, a series of levers arranged in airsoppesitely disposed upon each side o said housing and pivoted upon said rods, a magnet k 'for each lever and means for energizing and denergizing the same, display cards,`m'eans for 'suspending said cards between the inner ends of said levers whereby the cards have a true and free vertical movement,.said means including links extending vertically from the u per corners of each card to the corre.

spon ing inner ends of a pair osaid levers.
