CHARLES J. VINING, OF CLEVELAND, OHIO, ASSIGNOR TO FIELD AND HENRY J. FARWELL, BOTH OF SAME LEWIS C. MERRI- PLA CE.

ELECTRIC FIRE-ALARM AND NIGHT-CALL.

SPECIFICATION forming part of Letters Patent No. 433,584, dated August 5, 1890.

Application filed December 2,

To all whom it may concern:

Be it known that I, CHARLES J. VINING, a

time, as hereinafter shown.

That the said invention may be seen and fully understood, reference will be had to the following specification, and to the annexed drawings, making part of the same, in which- Figure 1 is a front view of the apparatus, A being the indicator, B the batteries, and C the alarm-bells. (Z d d and f are the wires of the return-current. e e e are the wires of the induced current. Fig. 2 is an interior view of the dial D of the indicator A, which dial, with its frame, is hinged to the indicator. Fig. 3 is also an interior view of Fig. 1, show- 0 ing the clock, which is directly back of the dial D, arranged to operate conjointly therewith, and the pins and lines. Figs. 4, 5, and 6 are detached sections of my improved apparatus.

Similar letters refer to similar partsthroughout the several views and specification.

The center portion of the dial D of the indicator A is made of hard rubberor the equivalents thereof. In the dial is a series of cono centric circles of holes, soplaced that they will correspond with the hours and half-hours of the clock E. Around the edge of the dial is anotherseries of holes. These holes last specified are numbered so as to correspond With the numbers of the rooms in which the alarms C, Fig. 1, are placed. On the back of the dial D and revolving on a pivot F is an arm G, Fig. 2, to which is attached a stem H, which is engaged by the hour-hand 7c of the clock E, and causes the arm G to revolve 1889. Serial No. 332,299- (No model.)

with the hour-hand until the arm G comes in contact with one of the pins J, which is attached to one of the induction-wires e and placed in the hole of the dial D to correspond Withthe hour on the clock E at which it is desired to sound the alarm in the room designated. Passing through the dial at K and brought in contact with the arm G is the return-circuit wiref. Therefore when the arm G, which is continually in contact with the return-Wire f, is brought in contact with one of the pins J the circuitis closed and the alarm is sounded in the room the number .of which corresponds to the number of the hole in which the pin L is placed. The pin L is connected with the same wire as the pin J. This pin L representsa series, all of the series being arranged over the plate M. Every returnwire on the end next the dial has two branches, as shown in Fig. 1, and also the pins L are al- Ways in position opposite the common switchplate M, hereinafter described. The other pin J is either in the marginal hole numbered to correspond with the number of the room or At the back of the dial D is a metallic switch-plate M, of the shape of Fig. 6, which is attached to the dial D by means of the pivots N, turning in the insulated supports 0 and forming an insulated pivotal switch-plate at 9, Figs. 4 and 5. Attached to the switchplate M at the point P is a stem R, which passes through the indicator A. On the end of the stem R is a knob S, of hard rubber or any other non-conductor of electricity. It will be seen that by pulling on the knob S the switch-plate M Will be brought in contact with all the pins in the holes in the edge of dial D, and by placing the holes so that it will come in contact withthe arm G a general and simultaneous alarm will be sounded in all the rooms having a connecting-bell.

the others the leaves or springs brought in contact with them will spring, as shown at 2', Fig. 4, and allow the remaining leaves to come in contact with their respective pins.

The alarm-bells may be of the ordinary kind with the common spools or coils, attached to which is the ordinary armature arranged to operate conjointly with the said apparatus.

If it is desired to ring thealarm in room No. 1 at four oclock, the pin L is placed in the hole No. 1 and the pin J is placed in the hole that corresponds with 4:? on the clock E. The arm G, being engaged by the hourhand of the clock, will'come in contact with the pin J at the same time that the hour-hand points to 4. The circuit .is thus closed through the following connections and the alarm is sounded: from battery B through wire D, branch cl, through the alarm, returning through wire 6 and branch y thereof to pin J, and thence through arm G and wire f to battery.

In givinga general alarm the pin J is placed in the hole corresponding to the desired time and the knob S is pulled to bring the plate M in contact with the pins L. The bells are in multiple are, as shown, and the course of the current for the general alarm is from the battery over the wire D-and its branches (1 to the bells, that portion of the current from the left-hand bell No. 1 going directly to the pin J over the return-wire e and its branch y, while the portions of the current from the other bells go to plate M over the several return-wires e and their respective branches as M. These currents unite on said plate, and thence pass through the branch 00 of the first return-wire e, and thence to the pin J, over branch y and to the battery through the arm G and wire f.

I claim as my invention- 1. In combination with a clock and an hourhand thereon, a perforated dial arranged in front thereof, an arm pivoted at the center of said dial, a projection upon said arm with which the hand engages, pins removably fitted in the perforations of said dial for making contact with said arm, and an electrical circuit including an alarm and having its terminals connected, respectively, with the pivoted arm and pins, for the purpose set forth.

2. In combination with a clock and an hourhand thereon, a perforated dial arranged in front thereof, an arm pivoted at the center of said dial, a projection upon said arm with which the hand engages, pins removably fitted in the perforations of said dial for making contact with said arm, and an electrical circuit including an alarm and having its terminals connected, respectively, with the pivoted arm and pins, a switch M on the said dial, and connections between said switch and the main circuit, substantially as described. In testimony whereof I affix my signature in presence of two witnesses.

CHARLES J. VINING.
