SIGNAL-RECEIVER.

Specification of Letters Patent.

To all who 17bit may comer/1 Be it known that 1, CHARLES A. Bans, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Signal-Receivers, of

ploying centrally or intermediately pivoted armatures carrying the signal producing devices or clappers and operating switching devices for alternately including and excluding the operating coils of the signalreceivers in and from circuit. a

My invention has for its object the provision of an improved construction whereby the armatures may have better control over the switching devices whose operations they govern.

My invention is shown in the accompanying drawing illustrating the preferred embodiment thereof in which- Figure 1 is an elevation of my improved signal receiver. Fig. 2 is a plan viewof the structure shown in Fig. 1, Fig. 3 is a sec tional view on line 3-3 of Fig. 1, and Fig.

1 is a detailed view inelevation showing the armature and switching mechanism more plainly.

Like parts are indicatedby similar characters of reference throughout the different figures.

The signal. receiver illustrated is an electromagnetic bell including two gongs 1, mounted upon a board 2, and operated upon by a clapper 3 normally held midway be tween the gongs by means of the spring mechanism of my invention which readily adapts itself to this purpose. The stem 4.- upon which the clapper is mounted is carried upon a bent finger 5 that is preferably integrally formed with, and which projects outwardly from the armature 6 that is mounted to face the lower poles of the magnet spools 7 that are mounted upon the lower face of the board 2. The two cores of the spools 7 are included in magnetic circuits, the magnetic circuit of the left hand "spool comprising the horizontal branch of armature on the other side. lingers, say the finger 11, carries a plug or are brought together as illust Med and carry the pivot pin 10 located considerably above the armature and midway between its ends, this pin pivotally supporting the armature by passing into the finger projecting upwardl y from the arnlature on one side and the finger l1 projecting upwardly from the One of these body of insulating material 12 which is interposed between and normally engages two Patented Nov. 10, 1914. Application filed April 2 1, 1911. Serial No. 623,041.

springs 18 141: by which the stem 4: is held in central position when the signal receiver is normal. or idle. These springs also constitute terminals for the windings of the spools 7, one spring constituting a terminal for one spool winding and the other spring a terminal for the other spool winding. The remalning termlnals of these spool.

windings are in common connection with a key 15 adapted when actuated to become connected with one terminal of a battery 16, the other terminal of which is connected with a contact 17 through the frame of the bell. This contact 17 is carried by and pro jects below the armature 6 and is normally in engagement with the lower ends of the springs 1.3 1 1 so as to normally centrally position the clapper. By means of the circuit illustrated the battery 16 is brought into association with the two spools 7 by means of the keylii. The springs 13 and 14: are mounted at their upper ends and, as illustrated, are free to swing at their lower ends. When the bell is idle the contacts 13, 14, 17 are in electrical connection and when the key 15 is depressed one or the other of the spools will predominate in attracting the armature so as to swing it one way a limited distance, this movement culminating in a separation of the contacts that previously closed circuit through the spools toward which the armature moved, whereupon the companion spool will reverse the movement of the armature and bring the armature into the position in which the circuit through this latter spool will be opened, whereafter the first spool will again attract the armature, these operations continuing until the key 15 is released. NVhile one battery common to the two spools is shown I do not limit myself to this arrangement.

The pivot 10 is located between the body of insulating material 12 and the armature 6 and consequently the contact 17 is carried by the armature whereby wide relative movements, between the contact 17 and the two contacts 13 14 are assured. For example, assume that the armature is moving in a clockwise direction. The body of insulating material 12 will engage the spring 14 and move it to the right while at the same time the armature itself carries the contact 17 to the left. Upon the reverse movement of the armature the left hand spring 13 is moved to the left and the contact 17 is moved to the right. 7

The advantage of my improved mechanism will be appreciated by those skilled in the art.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent the following:

magnetic spools; an armature which is pivotally mounted between its ends; two springs 13 14 connected with terminals of the spools; an element 12 interposed besprings and carried by the armature; and a contact element 17 also carried by the armature and cooperating with the aforesaid springs for controlling the circuit arrangethe armature swings being located between the elements 12 and 17 while the springs are ment with the elements 12 and 17, the elemounting for the springs and the axis of movement of the armature.

In witness whereof, I hereunto subscribe my name this eighth day of April A. D.
