INSERT FOR TIMERS.
This invention aims to kprovide novel means whereby a new set of contact terminals may be assembled readily with a timer, the device being of peculiar utility in repairing a worn timer, although the structure byno means is confined to repair work. i Figure 1 shows in elevation, a timer wherein the device forming"y the subject matter of this application has been mounted; Figure 2 is a section on the line 2-2 of Figure 1, the line 1-7-1, in Figure 2 indicating the view point in Figure 1; Figure 3 is a section on the linel 3-3 of Figure 2, remote parts being omitted.
The numeral 1 designates a timer carried by a supporting bracket 10. An insulating 'track 2, which may be denominated a main track, is located within the casing 1. Terminals 3 are embedded in the track 2 and carry connecting elements 4, extended outwardly through the track 2 and through insulating thimbles 5 seated in the rim of the casing 1,.nuts 6 being threaded on the connecting elements 4 and cooperating with the thimbles 5. A cam shaft 11 extends into the casing 1.
In carrying out the invention, there is provided an annular auxiliary track 7 which is made of insulating material. The track 7 may comprise an inner ring member 8, an outer ring member 9, and an annular spacer f 12 therebetween, the spacer' having seats or notches 14 in its outer edge. n
Annular resilient retainers 15 are supplied, ea'ch retainer comprising a body 16 having an inwardly extended flange 17 at one end, and having a short outstanding finger 18 at the other end. The flanges 17 are received in the seats 14 of the spacer 12, between the members 8 and 9 of the track 7. Securing elements 19 (which may be copper rivets) pass through the members 8 and 9 of the auxiliary track 7, and through the flanges 17 of t-he retainers 15, the resilient body por- 2, 1923. semaine. 616,582.
tions 16 of the retainers being engaged with the main track 12, in electrical contact with the terminals 3, the fingers 18 coacting with the terminals 3 to hold the auxiliary track 7 in the posit-ion shown in Figure 2.
A socket 20 is secured at 21 to the cam shaft 11 and has an outstanding arm 22 provided with a tubularguide 23 disposed parallel to the cam shaft 11. A brush 24 (which may be made of carbon) is mounted for reciprocation in the guide 23. A compression spring 25 is located in the guide 2S and advances the brush 24, so that the brush bears against the auxiliary track 7 and traverses the auxiliary terminals 19. A cir cuit is established through the connecting element 4, the terminal 3, the retainer 15, the auxiliary terminal 19, and the brush 24.
We claim As an article of manufacture, an auxiliary timer-track, comprising an inner ring, an outer ring, an annular spacer between the rings and having notches in its outer edge, the notches extending entirely through the spacer, a plurality of retainers each com" prising a straight body disposed parallel to the axis of the track and bearing at one end upon kthe periphery of the outer ring, said end of the body being provided with a rectangularly disposed flange received in one of the notches of the spacer and engaged by the adjacent faces of the rings, securing elements passing through'the rings and the flanges of the retainers, the securing` elements constituting terminals for the track, and the bodies of the retainers being supplied at their opposite ends with fingers which extend away from the axis of the track.
In testimony that we claim the foregoing y as our own, we have hereto 'affixed our signatures.
