HUGO P. FREAR, OF SAN FRANCISCO, CALIFORNIA.

STREET-ANNUNCIATOR.

SPECIFICATION forming part of Letters Patent No. 567,643,-dated September 15, 1896.

Application filed November 13, 1895. Serial No. 568,766. (No model.)

To roll whom, t may concern:

Be it known that I, HUGO P. FREAR, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Annunciators for Streetn Railway Cars or other Vehicles; and I hereby declare the following specification and the drawings therewith to be a complete description of my improvements.

My invention relates to apparatus for announcing the names of streets or stations as they are approached by street-railway cars or other vehicles, operated by means of an electrical current automatically or by act of an attendant, preferably by means of devices on the line that will close the electrical circuit at the proper points on the route of the car.

My improvements consist of an apparatus to be fixed in a passenger car or carriage in a conspicuous place and in aseries of tablets or cards marked with the names of stations or the streets crossed and mounted on a revolving drum or cylinder in such manner that they will successively expose tothe view of passengers as the streets are approached, the cylinder being turned successively the distance of one card or tablet as each street is crossed.

My improvements further consistin electrical apparatus to operate or turn the cylinder by means of an .electromagnet and armature that by a pawl turns the cylinder so as to expose the name of the next street to be crossed or a station approached, and at the same time a bell or other audible device calls the attention to the tablet and name of the street being exposed. To this purpose I employ devices as shown in the accompanying drawings, in which- Figure l is a front view of one of my improved annunciators with the name of a street exposed. Fig. 2 is a sectional end View of the same apparatus, taken on the line m in Figs. l and 3. Fig. 3 is a longitudinal section through the revolving drum or cylinder, showing the manner of arranging the actuating mechanism.

Similar letters of reference indicate corresponding partsin the different figures oi the drawings.

The main case A, which contains the various elements 0f the annunciator, consists of the ends B B2, preferably of wood, and an inelosing cover C, that can be made of sheet metal or thin wood.

A revoluble cylinder or drum D, preferably made of stiff paper, is mounted on pivots K K2, one having support in the bearing L2 and the other in a stud IV, projecting inward from the plate L, as seen in Fig. 3. This revolving cylinder or drum D consists of two metal end plates E' and E2, the latter being in this case indented to form a cl1amberE2, in which is placed the electric actuating devices to be hereinafter described.

Around the drum D, and supported in the 'heads or end plates E E2, are a series of parallel rods F, on which swing the hinged tablets G, on one side of which are printed the names of streets in the route, in the manner shown in Fig. l. These rods can be inserted and removed through a hole or slot Z in the end B of the case or through the plate L, so the tablets can be' removed, replaced, or changed as an alteration of the names or information thereon will require. These tablets G are preferably of stiff paper or thin sheet metal, reinforced at the ends by bands I-I of thin metal, bent so as to form hinges or eyes through which the rods F pass, a Icentral or supplementary hinge I-I2 bein-g provided to prevent the tablets Gr from bending at their center, or when the drums are made of a length to require such support a middle fiange around the drum D can loe provided, the rods F passing through the Iiange the same as in the heads E E2. As the drum D revolves, these tablets G, by reason of their gravity, take the4 position shown in Fig. 2, the preponderance of weight being on the inner side and tending to revolve the drum D backward, thus keeping it in contact with the detent I, that engages the teeth of the pawl ring or rack J, as shown in Fig. 2.

The teeth in the pawl-ring J correspond in number to the tablets G, and are attached to or integral with the indented end E2 of the drum D, as shown in Fig.

The drum D is supported on the trnnnions K K2, made integral with the removable plate L and the bearing L2, as seen in Figs. l and 3, the. plate L being large enough in diameter s0 that all the actuating mechanism Which is attached to the plate L can be removed intact through the side B2 of the main case. This is a convenience in assembling the apparatus, but is not required in changing the tablets G and the rods F, as has been before explained.

Referring to Fig. 2 it will be seen that one of the tablets G is exposed in an inclined position at M, its top resting against the front of the main case at N, so the face can be conveniently seen by the passengers Within a car in Which the annunciator is mounted, while the back of the preceding tablet is seen at O.

IVithin the indented head E2 of the drum D, and attached to the plate L', I tix an electromagnet P, energized by the conductingwires Q/ Q2.

Beneath the electromagnet P, I place a pivoted armature R, that when the electric circuit is closed rises to the position shown by dotted lines in Fig. 2, and by means of the pawl S, which engages the rack J, turns the drum D the distance of one notch, causing the front tablet at M to be released at N, so it will fall down into the position O, exposing a new tablet and the name of another street or station at M. 'Io regulate the stroke ofthe armature, an adjustable screw X is provided, on which the armature-bar R rests when the electric current is open.

The backs O of the tablets G can contain any printed information of interest to passengers, an advertisement, or may be left blank, as shown in Fig. l, and their number can be arranged for the required num ber of announcements, the tablets G being omitted when too many in number. At the end of a journey, or at the beginning, the attendent turns the drum D to correct the tablets G and adjust them to names to be announced. At the same time the electric circuit is closed and the armature R rises, a ham mer T thereon strikes the bell U, calling attention to the change of the tablets at M and the name of the next street.

The bell U is mounted on a stud V, projecting from and integral with the plate L, so that this, with all the electric elements, can be removed with the plate L from the chamber L3 for inspection or adjustment, the drum D being sustained by the tablets G, resting on the bottom of the containing` case A.

Attached to the stud V is a detent I, that prevents the rack J and drum D from turning` backward, a constant strain in this direction being provided by the Weight ot' the tablets G, which on the rear side stand farther out from the axis K K2, as seen in Fig. 2.

The Wires Q' Qin the case of an electricallyimpelled car can be connected With the motor or line-current in any suitable manner, or on cars impelled by other than electric apparat-us the Wires Q' Q2 can be connected to a battery conveyed on the car in Which my improved apparatus is mounted.

The circuit can be opened or closed by means of contact points or stops automatically, such contact-points being on the Ways, the wire overhead, or otherwise, or by a push-button. Such devices being Well known, capable of diiierent arrangement, and not forming a part of my present invention, I do not describe them here.

The position of the drum D and tablets G can also be adj usted by an attendant directly pulling or pushing the drum around the desi red amount, access being had from the front of the containing case.

The electric elements I inclose Within the intended chamber E3 for protection and to save room; but it is obvious that these can be placed on the outside of the main case A for example, attached to the outside of the plate L/-or so placed that the pawl S Will act on an outside rack J, but the arrangement shown is preferable.

Having thus described the nature and objects oi'` my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a street-annunciator, a main containing case, open at the front, therein a revoluble cylinder or drum provided with hinged tablets in the manner described, the drum indented or provided with a chamber at one end, and receiving Within its contour the electromagnetic actu-ating apparatus, in the manner substantially as described.
