UNITED STATES AUGUST A. KLANN, or WAYNESBORO, VIRGINIA.
ELECTROMAGNETIC RELAY.
Application filed July 24, 1925. Serial No. 45,898.
This invention relates to improvements in electromagnetic relays, and it consists of the constructions, combinations and arrangements herein described and claimed.
An object of the invention is to provide an electro-magnetic relay which is particularly adaptable to uses in pipe organs, one 01 the improvements residing in the provision 01 a removable contactor, the removal of which may be effected when required without disturbing any other part of the relay.
Another object of the invention is to provide an electro-magnetic relay in which the stationary contacts are mounted in a novel manner thereby making the work of connecting the necessary wires'much easier than at present.
Other objects and advantages will appear in the following specification, reference being had to the accompanying drawing, in which Figure 1 an elevation of the improved electro-magnetic relay, an associated electrical circuit being illustrated diagrammatically.
Figure the relay.
Figure 3 is an inverted plan view of the relay, the guard plate being omitted.
Figure 4 is a detail perspective: view of the removable contactor.
While the el-ectro-magnetic relay is capa ble of employment inconnection with uses other than the one herein mentioned the particular purpose is to relay electrical current from the contacts 1 and 2 of, a key 3 to an electro-magnet 4, which, for example,
is a centralvertical section of may be regarded as cont-rolling the air supply to certain organ pipes (not shown).
\Vires 5 and 6 connect the source of current 7 with one end of the winding of the electro-magnet 8 and with the contact 2 respectively. The wire9 connects the other end of the magnet winding with the contact .1. Upon depression of the key 3 the pull wire 10 draws the contact 2 into engagement with the contact 1, closing the relay circult and attracting the armature 11. The armature 11 and base 12 are cast of an alu minum alloy. The armature has inserts 13 Fig. 2) of magnetic metal so that the arma ture is attracted by the electro-magnet. A
wire 1 1 connects one side of the eleetro-magnet 4 with the source of current 15, a wire 16 connecting the other side of the source of current to a screw 17 on the base 12. A wire 18 connects the other side of the electromagnet with one of a plurality of contacts 19. The remaining fixed contacts will be connected to other and similar magnets (not shown). I
' A bar 20 rocking in recesses 21 in pendant bosses 22 upon the base 12 furnishes the pivotal mounting of the armature 11. A spring 23, connected at its ends to a projection 2 1 of the armature and a pin 25 on the base,'serves to hold the pivot bar 20 in place but more particularly provides a positive currentconductor from the screw 17 to the armature.
A contactor .26 is engageable with the fixed contacts 19 when the armature 11 is attracted by the relay magnet S, as stated. The free extremity of the contactor is slotted at 27 to provide a plurality of cont-actor fingers equal in number to the fixed contacts. The contactor is bent as shown so that the contacts 19 may be reached. The contactor is easily removable from the arma ture 11 by loosening the screws 28 and clamp 29. This clamp holds the contactor in place upon the armature, but by loosening the screws, as stated, the cont-actor is readily removed and replaced by another without dis-- turbing any other parts of the relay. This feature is of considerable importance in a device of this kind.
A'smallpiece of felt attached to the free extremity of the armature 1.1 is contactible with the base 12 when the armature is attracted and serves to deaden any sound. A felt or other washer 31 upon a fixed but adjustable screw 32 limits the downward movement of the armature 11 under the influences of gravity and the spring Jaws 33- carry strips of insulation 34. through which the fixed contacts 19 are thrust and by which they are rigidly held. The lower extremities of the strips of insulation are fast .upon a short bar of wood 35 to which bar a guide plate 36 is secured bynieans of screws or the like.
The operation is doubtless understood already, but may be briefly reviewed to admagnet 4 the aforesaid engagement of the contacts will cause current to flow from the source 15 over wires 16 and 17, over spring 23 to the armature 11 and to the contactor 26, contact 19, wire 18, elect'ro-magnet 4 and over wire 14 to the other side of the source of current 15.
The particular manner of mounting the,
contacts 19 makes a more rigid yet simple construction. Again the particular manner of mounting the contactor 26 adds efficiency to the relay. It may happen that one of the contactor fingers breaks. In suchevent it becomes necessary to remove the entire contactor, andin the-improved relay this is done by simply loosening the screws 28 and the clamp 29 so that the contactor is readily taken out and replacedby another.
The electro-magnetic relay takes up but a small amount of space making it possible to assemble a complete set of. relays in any easily accessible space which may not be utilized by other parts of the organ in which the relays are used. The base '12 has a right angled portion 37 which is readily applicable to a wood bar 38 for the support of the relays. The relay is further designed to work on a minimum amount of current, taking no more than the ordinary chest magnet. The simplicity of the relay is self-evident because it has only one moving part, namely the armature 11.
