CORPORATION F NEW JERSEY ELECTRICAL CUT-OUT Application filed January E), 1932.
This invention relates to an electrical cutout such as is ordinarily used on or in c onnection with generators used for charging storage batteries, and is especially adapted for use in connection with generators used on automotive vehicles.
A cut-out for use on automotive vehicles should be of as few parts as possible and rigidly constructed to withstand the vibrations and shocks to which the device is subjected.
My improvedform of cuteout is depicted in the attached drawing, wherein Figure 1 is a part-sectional and part-elevational view through the device attached to a pair of mounting lugs.
Figure 2 is a top plan View of the device shown in Figure 1.
Figure 3 is a part-sectional and part-plan View looking down on the top of the cutout, but with the armature removed and without the mounting lugs.
Figure 4 is a view looking from right to left in Figure 1.
Figure 5 is a fragmentary view looking at the bottom of the base carrying the cutout. l
Figure 6 is a plan view of a modified unitary terminal strip.
Figure 7 is a side-vievw of Figure 6.
Figure 8 is a perspective View of a modified form of mounting plate which may be used in place of the mounting lugs shown in Figure 1.
Figure 9 shows a further modified form of mounting plate.
In the several views, the same numbers refer to corresponding parts.
The cut-out comprises a yoke 1 of magnetic material, having arms 2 and 3, and a core 4. The yoke 1 is supported on a base member 5 but insulated therefrom by an insulator 6 which is doweled by dowels 51 on the base 5 so as to prevent its turning thereon. Furthermore, the yoke itself is doweled to the base 5 by insulated doweling means, one of which, 52, is shown, the other being hidden by the auxiliary extension member 48.
The arm 3 of the yoke has a portion 7 bent Serial No. 585,653.
over in a direction away from the core, and at a point adjacent the bend, is provided with a slot through which one end of the armature 8 extends. The armature 8 has a portion 9 bent downwardly immediately after it passes through the slot in the yoke arm 3. This downwardly-bent portion 9 is provided with a stop-rivet 10 of non-magnetic material, and the lower end 11 of the armature is bent outwardly in a direction transverse to the axis of an adjusting screw 13 carried by the bent portion 7. Positioned between the screw 13 and the portion 11, is a tension spring 12.
Fastened to the outwardly-bent portion 7, as by screws or rivets 14, is a thin flat spring 15, the other end of which is riveted by rivets 16 to the armature 8 intermediate the leg portions 2 and 3 of the yoke 1. The free end of the armature 8 overlaps the leg portion 2 and is provided with a contact 17. A cooperating contact 18 is carried on a metal strip 19 which is positioned around the end of the core 4, but insulated therefrom by insulators 20, 21, and 54. The contact plate 19 is provided with a slotted lug 22 within which is positioned and soldered thereto, one end 23 of the series winding 24. The other end 25 of the series winding passes through the yoke 1, but is insulated therefrom and is soldered to the terminal strip 26 at the point 27. The shunt winding 28 is placed between the series winding and the core and has one end connected to the yoke 1 and the other end brought out through a terminal 29 fastened to the base 5.
One end of the core 4 is threaded at 30 and the nut 31 serves to clamp the terminal 26, together with the terminal 32, with their associated insulators, into position on the base 5. It will be noted that the base 5 has downwardly-extending lianges, the opposite flanges of which are slotted or notched out at to receive the terminal strips 26 and 32 with their associated insulators. These flanges on opposite sides of the notches 33 are provided with screw-holes whereby mounting lugs and 35 may be attached as shown in Figures 1 and 4, Each lug is provided with a slot 36 for attachment to the bow of the generator on which the cut-out is adapted to be mounted. The arms 2 and 3 of the yoke 1 are provided with slots 37 for receiving projections 53 on the insulator 54, thereby anchoring this insulator. The insulator 54 also has a lug 56 to engage a slot in the core to prevent the core from shifting. The slot 37 in the arm 2 allows the contacts 17 and 18 to be exposed to view from the end of the cut-out.
In Figures 6 and 7, I have shown a unitary form of terminal strip comprising the terminal 32 and a forked end, and with the insulators 38 and 39 riveted thereto by the rivet 40. This form of terminal is adapted Yto take the place of the unitary form shown in Figure 1, wherein the insulators 41 and 42 are riveted by the same rivet 40 to the terminal strip 32.
In Figures 8 and 9, I have shown different styles of mounting plates which may be quickly substituted for the mounting lugs 34 and 35. These different designs of mountings may be furnished with the cut-out so that the cut-out can be applied to various styles of generators now on the market. The-,plates are provided with flanges 43 and 44 to fit the flanges on the base 5. Notches 45 are provided in these flanges in order to clear the terminal strips 26 and 32 with their associated insulators. Screw-holes 46 are used to fasten these mounting plates to the base 5 by screws 47, as shown in Figures 1 and 4.
l In Figure 5,41 have illustrated an auxiliary terminal 48 carried on the end of the core-stud 30 beneath the lock nut 31. The end of this terminal is provided with a screw 49 under which a wire may be fastened.
It sometimes happens t at the generator has a very short terminal not long enough to extend out to the terminal 32, in which case it may be connected to the auxiliary terminal 49.
In the assembly of the cut-out, when the amature 8 is assembled, the contacts 17 and 18 just come together when the stop 10 engages the yoke-arm 3. Then the armature 8 1s bent about the pivot point at the slot in the yoke-arm 3 to give the required gap between the contacts 17 and 18. After this adjustment is made, the final setting is given when the current is passed through the cutout, by means of the adjusting screw 13 and tension spring 12, a nut 50 being provided to lock the screw 13 into adjusted position.
From what has been said, it will be ob served that the manner of insulating the terminal strips 26 and 32, and positioning these, with their respective insulators, in
' slots in the flange base, obviates any danger whatever of these terminals becoming loose and swinging out of position whereby they might become grounded. Furthermore, by
providing interchangeable mounting lugs or plates, the eut-out can be quickly adapted for use on various styles of generators. Thus, the cut-out itself may be termed a universal one which can be used in any generator b merely changing the mounting lugs of t e plates. It will also be observed that the various connections are securely anchored so as to withstand the vibrations to which the cut-out is subjected.
Having thus described my invention, what I claim is:

In a device of the class described, a base, a U-shaped yoke of magnetic material supported on the base but insulated therefrom, a core positioned between the arms of the yoke and acting to clamp the yoke to the base, a Winding on said core, one arm of the yoke being bent over and away from the core and having a transverse slot therein adjacentthe bent-over portion, an armature positioned adjacent the free end of the core and extending between the arms of the yoke and having one end extending through the said slot in the yoke arm, said armature 90 end lfeing bentdownwardl toward the base after passing through said7 slot, said downwardly-bent armature portion being turned outwardly at its extremity in a direction the saine as said bent-over end of the yoke, 9,5 an adjusting screw carried by said yoke bent-over end, a tension spring positioned between the sci-ew and the bent extremity of said armature, and a flat spring positioned in said slot and fastened at one end to the armature between the yoke legs, and at the other end to the bent-over yoke end.y
