1 Application filed. December 6, 1907. Serial No. 405,398.

To all whom it may concern:

Be it known that I, JAMES E. Buizen, a citizen of the United States, residing in Lincoln, in the county of Lancaster and State of Nebraska, have invented a new and useful Improvement in Ringing-Machines, of which the following is a specification.

My invention relates to improvements in rotary pole changers of that type comprising a motor, a motor circuit, a circuit maker and breaker mounted upon the armature shaft of the motor7 a bell circuit7 and brushes included in the bell circuit and contacting with the circuit maker and breaker.

The object of my invention is the provision of a simple. durable and efficient frame structure for a rotary pole changer of the above stated character.

The invention consists of the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, wherein z- Figure 1 is a view in side elevation of a rotary pole changer embodying my invention. Fig. 2 is a view in side elevation thereof. Fig. 3 is a top plan view thereof. Fig. t is a detail side elevational view of the circuitbreaker and maker. Fig. 5 is a sectional view of one of the bell circuit brushes.

My improved frame structure comprises a circular base. 1, and an inverted U-shaped member 1 secured at its ends to the base 1 by bolts 1b. A bearing member 6 (see Fig. 4 of the drawing) is provided with a screw threaded stem 6a through the medium of which it is secured to the base 1. To permit of its application and removal and to permit of its adjustment by means of a wrench7 the bearing member 6 is provided with an angular portion 6b. 1n its upper surface the bearing member 6 is provided with a socket for the reception of a jewel bearing 6. The lower end of an armature shaft is journaled in the bearing 6 and the upper end of the shaft is recessed as at 6d for the recept-ion of the lower end of a bolt 7 which is threadedly mounted in the cross bar of the member 1a. To permitv of its adjustment the bolt 7 is provided with a milled operating head 77 and the bolt is secured in its adjusted position through the medium of a jam nut 7 I The drum armature 8 of a motor is secured to the shaft 5 and is located within a easing 2. The motor casing 2 carries the field coils t and is secured to the sides of the member 1a through the medium of arms 2a. The arms are formed integrally with the motor casing 2 and project in opposite directions therefrom. The arms 2 are provided with enlarged attaching flanges 2b, bolts 2C passing through the sides of the frame 1a and engaging the attaching flanges 2l. An arm 8 extends downwardly and forwardly from the cross bar of the member 1a and carries the brushes Q of the commutator 10. The motor is supplied with current froin a battery 21, wires 22 leading from the battery to the armature brushes 9. and wires 23 lead from the wires 22 to the tield coils 4. The motor is of the usual construction and mounted upon the armature shaft 5 thereof is a circuit breaker and maker of the usual construction.

By reference to Fig. 4 it will be seen that the circuit breaker and maker comprises metallic contact cylinders 1Q, and metallic contact lingers 13 separated by insulation 11. The brushes 16 and 18 of a bell circuit contact with the cylindersl 12 and are con; nected to the bell battery by wires '24. The brushes 17 and 19 of the bell circuit contact with the lingers 13 and are connected to the bell by wires Q5. The brushes 16, 17 and 1S are carried by a vertical standard 15 which is provided at its lower end with a horizontally disposed attaching flange 15u. The standard 15 is secured to the base 1 through the medium of a bolt 15" which passes through the base and through the `flange 15a. The brush 19 is carried by a` vertically disposed standard 2O which is provided at its lower end with a horizontally disposed attaching flange 20, this standard being secured to the base by a bolt 20" which passes through the base and through the flange. Each of the brushes 16, 17, 1S and 19 comprise a cylinder a. mounted in the sleeve of insulation which is located in an opening 15 formed in the standard. The sleeve a. carries a brush (l and a threaded bolt 15d. and mounted between the brush and the bolt is a coiled expansion spring 16. The bolt 15d retains the spring 16 in applied position and provides means by which the tension of the spring may be adjusted. The bolt is held against movement by a jam nut 15e. The pole changer is adapted to be secured in applied position through the medium of bolts l passing through the base 1 and engaging a suitable support.

From the foregoing description, taken in connection with the accompanying drawings, it should be apparent that I provide a iframe structure Which Will permit the parts of a rotary pole changer to be compactly assembled, and which is simple, durable and ehcient.

Having thus described the invention, what I claim is A frame structure for pole changers, co1n ment with the bearing, a motor casing, arms secured to the ends of the motor casing and extending in opposite directions therefrom, attaching lianges secured to the ends of the arms and secured to the sides of the U- shaped member, and vertically disposed brush supporting standards, each standard being` provided with a horizontally disposed attaching ange secured to the base.
