Specification of Letters Patent.

Patented Dec. 17, 1907.

Application iiled Julyl 8| 1907. Serial llo. 382,582.

To all whom it Imay concern:

1, LEE KIBLINGER, a citizen of the UnitedStates, and a resident of Jackson, in the parish of East Feliciana and State of Louisiana, have invented a new and Improved Pole-Changer, of which the full, clear, and exact description.

My invention relates to pole changers, my ymore particular. object being to provide a form oi pole changer in which vthe momentumoii the vibrating hammer is employed. in such a way as to increase the abruptne'ss of the inalie-and-break.

My invention i'urther relates to' improving the magnet used in the pole changer so as to enable this magnet to exert a greater attraction for the portion serving as an armature.

My invention relates still further to certain details of construction for improving jthe general eiiiciency oi' the instrument.

Reference is to be had to the accompanying drawings forming a part oi this specification, in which snnllar characters oi reference indicate',corresponding parts in all the iigures..

Figure 1 is a plan view showing one form yof my ole changer, in which the hammer horizontal plane and lin which attracted. by the 2 is a vertical 1, looking in the direction olf the arrow, and showing the special l'orin oi magnet with broad pole ieces both acting the same time upon theswinging hammer or armature; Fig. 3 is a view partly in section and partly in side elevation, of another iorin ol my pole changer in which the armature swings in a vertical plane; and Fig. 4 is a plan view ol the conthe hammer is powerfully special iorin oiv magnet, Fig.

arrangement ci' the contacts and the parts associated therewith.

Mounted upon a base 5 is an electromagnet 6L ol horse-shoe i'orin and provided with flattened cores 7 terminating in flattened pole pieces 7 a el opposite polarity. An

upon a rod 9 and is pro- 10 adapted to register This rod 9 is provided with a resilient portion 11 constituting a spring and held in a post 12 which is bifurcated for the purpose.A Encircling 'the rod 9 is a sleeve 13 of insulating material pref-- section is mounted vided with poles with the poles 7 1.

erably hard rubber, and encircling this of metal provided with sleeve is a ring 14' 16 oi' metal, preferably contact points 15,

latinum.

Contact pointsv 17, 1 rectly upon the rod 9. Stationary contact springs 19, 2O are dis'osed oppositely to each ,otherl so as to be engaged by the contact points 15, 16, and similarly contact springs 21, 22 are disposed opposite the contact members 17, 1S.

Froma batt-ery binding post 25, the latter being connected by a wire 26-with the magnet 6. From this magnet a wire 27 leads to a binding .post 28, and this ost is connected by a wire 29 with the meta lic sleeve 14.

From the battery 23 a wire 80 leads to `a switch 31, andfrom the latter a wire 32 leads to a binding post 33. Connecting this binding post with the post 12 is a wire 34 A service wire 35 is connected with the contact spring 21, and from this spring a'wire 36 leadsrto the contact spring 20. Another service wire 37 leads to the Contact spring 22, which is connected by a wire 38 with the contact spring 19.

The operation of 1 and 2 is as follows: The spring 11 is curved slightly so that the rod 9 is normally held in such position that thecontact point 1S engages the contact spring 8 are mounted di- A 22. Suppose, now, that the service wires 35, -37 are connected up with an instrument through which the direction of the current isvk to bealternated. Suppose, now, that the operator closes the handV switch 31. A. circuit is completed as follows: battery 23, wire 25, wire 26, magnet 6, wire 27, binding post 28, wire 29, metallic sleeve 1.4, contact point 16, contact spring 20, wire 36, service wire 35, through instrument in which the current is to be alternated, then returning through wire 37, contact spring 22, contact point 18, rod 9, wire 34, binding post switch 31, and wire 30, back to battery 23.

his energizes the of its poles to attract the corresponding poles 10 ci the armature 8. This causes the banirner to be swung violently toward the lpole pieces and this movement breaks contact between the contact points 16, 18 and their respective contactsprings 20, 22, so as to momentarily open the circuit. The momentum oi the-armature carries it into its extreme position, thereby causing contact point 17 to engage thef contact'spring 21,

the form shown in Figs.v

3B, wire 32 23 a wire 24 leads to a 24, binding post magnet 6 and causes both CJi and similarly causes the contact point I5 to l and engage the contact spring 1Q. The circuiti is therefore again completed as follows: l battery 23, wire 24, binding post 25, wire 26, magnet 6, wire 27, binding post 2S, wire Il 29, metallic sleeve 14, contact member 15, l contact spring 19, wire 38, service wire 37, through instrument (not shown) in which 1 the current is to be reversed, returning by i wire 35, contact spring 21, Contact member 17, rofl- 9, spring 11, wire 34, binding )ost 33,

.wire 32, switch 31, wire 30, back to attery 23. Contrasting this circuit with tlie'onel previously traced, it will be seen that the j current passes through 4wires 35 37 in a direction contrary to that which it pursued ,l in the circuit lirst traced, l Owing to the curvature or set of the spring l 11, the instrument must always start when Il the switch 31 is closed, for the reason that l the current has a free escape through the l contact point 18 and spring l It will be seen. that cach successive pull of l the magnet 6 causes the rod 9 to be thrown iirst in one direction-ami then in the other, l the rod being always in rapid motion at the time when Contact is made and broken.

Iteierring to Figs. 3 and 4, most of the working parts are inclosed within a casing 39. A magnet 40 is suspended from the top ot' this casing and a hammer 41 is mounted rigidly upon the lower end of an armature lever 42. The latter is hung from a ivot 43. A plate 44 is rigidly connected Wit the armature lever 42 through a slot 45 contact points are and projects upwardly in the casing 39. The shown at 45a, 46, 47, 48, the two contacts last mentioned being insulated from the plate 44 by a sleeve 49 of insulating material preferably hard rubber. Contact springs 50, 51, 52, 53 are engaged by the movable contact points 46, 45, 48, 47, l in a manner which will be well understood by l reference to the contact mechanism shown in Fig. 1.

A wire 54 connects the contact spring 52 with the contact spring 51. A wire 55 con- I nects together the contact springs 50 and 53. ,l A wire 56 is connected with the contact spring l 51 and with the wire 54. lA wire 57`is con'- nec-ted with the contact spring 50 and with the wire 55. VThe magnet 4() is connected l with wires 58, 59. A wire 6l) connects the l magnet with a wire 61 leading to the contact point 4S, and a wire 62 connects the member 44 with a wire 58.

' The resiliency of the contact springs 50, 51, 52, 53 is alone sufficient to throw the plate 44,

eoi'isequ'ently the armature lever 42, i-n either direction after the completion of the stroke in that direction. In the form shown in Figs. 3 and 4, as well as in the forni shown in the other figures, the momentum of the hammer carries it past the magnet poles, the movement necessary for this purpose serving to break the circuit at the exact instant when the hammer is closest to the magnet poles.

The armature lever is maintained in such position as to enable the machine to start by virtue of a weight 42n which always insures a contact suiiicient to enable the current to iiow as soon as turned on.

The operation of the form shown in Figs. 3 and 4 will be readily understood. The contacts are made and broken substantially above described with reference to the other figures, and the direction of the current changed accordingly.

While for convenience I show m invention as applied to pole changers, it s ould be noted that I do not limit myself thereby, for the reason that various changes-may be made in the construction of the device and in the uses to which it .is applicable, without departing from the spirit of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. The combination of a magnet provided with a flat pole, an armature provided likewise with a flat pole adapted to revister with said flat pole of said magnet, meansIor mounting saidarmature so that the same can swine in a plane crossing the short diameter of said fiat poles, and a cont-act connected with Said magnet, said contact-being so disposed that the swing ci said armature o ens said Contact.

2. The combination of a ipolar magnet a single suf-inging member disposed adjacent thereto, a substansially U-sha-ped armature mounted upon said Swinginor member and provided udth poles adapted to mate the poles of said bi-polar magnet, said armature being mounted to swing back and forth across the poles ofsaid magnet without touching .the same, and contact mechanism to be opened and closed by movements of said swinging member.'

In testimony whereof I have signed my name. to this specification in the presence of two subscribing witnesses.

LEE KIBLINGER.
