TELEGRAPHIC APPARATUS.-

The object of our invention is to provide an electric telegraphic transmitting andreceiving apparatus, of extremely simple and cheap form of construction, adapted more especially for use in transmitting culinary and service orders in cafs, theatres, restaurants, hotels, factories, offices, dwellings, &c., and to that end my invention consists of the construction, combination and arrangement of the several parts thereof, shown and described in the following specification of which the'accompanying drawings form a part, wherein similar letters of reference designate like or equivalent parts wherever found throughout the several views, and in which Figure l is a front View of the dial of the transmitter, which is of similar form to the dial of the receiver also. Fig. 2 is a front view of the operating mechanism of the transmitter, located behind the dial shown in Fig. 1. Fig. 3 is a top View of the transmitter in central horizontal section of Fig. l, and Fig. 4 is a side view of such mechanism in central vertical section of Fig. 1. Fig. 5 desig-' nates the battery which operates theappara tus, and Fig. 6 is a front view (with the dial' removed) of the operating mechanism of the receiver. Fig.i7 is a side view of such re ceiver in central vertical section of Fig. 6 the magnets being omitted. Fig. 8 is a view of those portions of the device shown in Fig. 7 which operates the hands of the receiver, as seen from the top. Fig. 9 is a top plan view of the magnets shown in Fig. 6,-and the immediate adjacent mechanism operated thereby; and Figs. 10 to 15, inclusive, are various views of a modified form of receiving apparatus to receive and indicate orders received from more than one transmitting station.

As shown in Figs. 1,2, 3 and 4, the transmitter consists of a dial A, supported at a certain distance from a back plate B by means SPECIFICATION forming part of Letters Patent No. 540,899, dated June 11, 1 895.

Application filed October 20, 1894. Serial No. 526,451. (No model.)

of long screw bolts, and of a metallic frame a. The dial carries arranged .around the outer edge thereof a nu mber of skeleton cases I), provided with sliding ribs wherein are intro duced movable sliding cards or signs 1) provided with suitable lettering or marking, (not sh own,) that are held therein by fiat Springs 1;.

As an illustration We assume that the cards or signs are lettered as for use in a cafe. In a smaller circle of the dial and within the circle formed by the signs I) are arranged a' series of Roman or other figures as shown, and by means of the hands A and A which are manipulated by hand by means of the handles a. and a is indicated what refreshment is to be served and how many, so that the hand A indicates the refreshment and the hand A the number. On the largest diameter of the dial or at any other suitable point are also arranged in a circle figures 1 that may be used for any suitable purpose, and may for instance indicate the number of the table in a caf or restaurant, or any other thing.

Fig. 2 shows the operating mechanism arranged behind the dial A and the hands are connected therewith as follows: The large hand A is fixed on a hollow shaft 0, and the small hand A is fixed at the end of the shaft 0 which passes through the hollow shaft 0 as shown.

By moving one of the hands, for instance A in the direction of the arrow as shown in Fig. 1, the gear wheel 0 also mounted on the hollow shaft 0 is rotated. This wheel has twenty-four teeth and closes an electric circuit each time that one of these teeth is brought into contact with the projection 61 fixed to a vertical rod d that is kept in place by a suitable block d The other handA acts through its shaft 0' upon a wheel C with twelve teeth, corresponding with the figures of the dial A and brought into contact with aprojection e arranged on the blade a. The circuit being closed and broken by the action of the teeth of the rotating wheels the consequent electric pulsations are exactly reproduced at the hereinafter described receiver by passing through the tonguesf (which can be regulated as to their lengths), the posts f and the conducting blades 9 and g; the current of the blade g passing into the magnet D mounted on the pivot D and the current of the blade g passing directly to the receiver. The magnet D is equipped with two magnetized columns E and E, one on each side of one of the bobbins so as to cause the magnet to oscillate about half a revolution on apivot D, which carries a plate F with an appropriate inscription showing the receipt of the order. This signal is only visible when the current is established by means of the contact 0:, arranged at a suitable point of the receiver (see Fig. l), but always shows the other side when not acted upon by the current. (See Fig. 2. The positive and negative wires are connected with a suitable battery, placed in a box (Fig. 5); the positive wire being connected with the block (I by way of the conducting blade (Z and the negative wire having connection with the contact a: of the receiver and through that with the blade g of the transmitter. The pulsations of the electric current caused by the rotation of the wheel 0 pass through and energize the magnet G, and the pulsations caused by the rotation of the wheel 0' in like manner energize the wheel G, and in either case such pulsations pass through the actuating magnets of the bell J, and the two indicators arranged behind the windows m.

The receiver comprises, as above stated, a dial A similar to the dialA before described and supported in the same manner by screw bolts on a plate B, a frame a, the handles of the hands A and A being eliminated, the same being moved electrically.

The electric pulsations, caused by the movement of the hands of the transmitter, passiug through conducting blades j and thence into the magnets G and G, act each upon an oscillating lever H and H, fixed to the bases of forks E1 and H provided at their bifurcated ends with studs 11. The lever l-I connected to the fork H acts upon a ratchet wheel I with twenty-four teeth. This wheel corresponds to the wheel 0 of the transmitter. The lever H connected to the fork I'l acts upon the ratchet wheel I with twelve teeth,

which corresponds to the wheel 0 of the transmitter. The regulation of the oscillatory motion of the forks H 11 and the levers II and H, is effected by the blades 71., fixed to the latter and the flexibility of which is regulated by the screws h. The arrangement thus described, it will be easy to understand the working of the apparatus, which is essentially that of suitable gearing worked at a distance by means of electric pulsations governed by transmitting gear moved by hand and the receiving gear being moved electrically by means of forks with driving studs.

The receiver is provided at its upper end with a suitable signal bell J, arranged in the circuit formed by a blade j fixed to the two blades j, which rings when the needles are set in motion. The bottom plates B and B respectively of the transmitter and receiver are fixed at any convenient place by means of suitable hooks or clamps 7a.

The Figs. 10 to 15 show a modified form of receiver acted upon by two transmitters placed in dilferent localities. This arrangement is shown as an example, because it would be easy, by an appropriate change of the parts, to bring a receiver into communication with three, four or more transmitters.

The dial of the double receiver shown in Fig. 10 carries at its circumference a series of twenty-four skeleton cases Z, only dill'ering in form from those of the dials already described. In these cases are designated the names of the refreshments in the same order as in the two different halls No. l and No. 2. The large hand K indicates the kind of refreshment desired in hall No. 1 and the hand K those in hall No. 2. cle of this dial are arranged two small dials each carrying twelve figures. The one L designates the number of refreshments corresponding to the transmitter of ball No. 1, and the L accomplishes the same purpose for the transmitter ol' the hall No. 2. In two angles of the dial are placed windows m, the purpose of which will be described later on. The two large hands K and K are arranged as above stated, one on the central shaft 71 and the other on the hollow shaftn'. On each of these shafts is arranged a ratchet wheel 0 with twenty-four teeth (the number corresponding to the number of cases I) of the transmitters). Each wheel is driven by an oscillating fork p with studs 19', which forks swing on pivots 19 The hands of the small dials are also driven by a ratchet wheel r of twelve teeth, acted upon by a fork 0" provided with studs 4' and swinging on pivots The oscillatory movement of these forks is obtained by the contacts of the toothed wheels 0 G of the transmitters, these contacts being each repeated in the four magnets M. The oscillations of the forks are regulated by plate springs 15, fixed to oscillating pieces '6 which are adj usted. by set screws 1?.

Fig. 15 illustrates in elevation and in plan view the device indicating the place where the order is given. This arrangement consists of a table N divided in two parts. The upper part of this table is painted in any desired shade and when not in use is displayed before one of the windowsm provided in the dial of the receiver. The lower part shows the place from where the order is received. This table is kept at its upper end by an armature 'v of a magnet 11. This armature is pivoted at o to a vertical support 11 This apparatus, when brought in the electric circuit, causes the armature cto swing so as to display before the window at the designation given on the lower part of the table N. It comes back to its original position by pushing on the contact as, the purpose of which is to turn the \Vithin the inner cirplate F of the transmitter carrying the sign Served or any other desired motto as shown in Fig. 1.
