1 '0 all whom it may concern:

Be it known that I, GUSTAF LEANDER HAL- VARDSON, a subject of theKing of Sweden, residing at Roslagsgatan 59, in the city of Stockholm, Sweden, have invented Means for Driving (Ringing) of Church-Bells and the Like, of which the following is a specification.

Means for mechanical ringing of church bells and the like with the aid of electric current are already known. But the arrangements of this kind hitherto used or proposed are encumbered with serious disadvantages being bulky, heavy, expensive, little economic and liable to fail or get out of order, thus needing frequent repairs or changes of parts. By my invention all these disadvantages are removed. I have attained this result by driving the bell by means of an electric motor, the brush-rocker of which partakes in the movement of the rotor within suitable limits and by using a resistance which by means of a centrifugal regulator or the like is automatically in creased and decreased so as to correspond with the actual want of current. A movable magnetically actuated stopper is used for locking the brush-rocker in the starting position when the current ceases.

In the accompanying drawings, Figure 1 is a schematic side view of the bell rung by an electric motor. Fig. 2 is a schematic view of the motor on a larger scale. Fig. 3 shows the automatic resistance on a larger scale. Figs. 4:, 5, 6 are diagrams of motor and resistance, the former being series wound in Fig. 4, shunt wound in Fig. 5 and compound wound in Fig. 6.

concentrically with the pivots 2 of the bell 7c is fastened a grooved-wheel 3 or the like, to which power is transmitted from an electric motor m by means of a chain-wheel 1 and a flexible member 1, consisting partly of a chain, partly of wire rope. At the point farthest from the motor the rope may be fastened to the grooved-wheel 3 so as to absolutely prevent sliding. An extra gearing 9 may be used as shown in Fig. 1 if there is not space enough for a wheel 3 of large diameter. In Fig. 2 I have shown a motor with four poles. This number of poles is suitable, but other numbers may be used.

The brush-rocker 6 with brush holders 7 and brushes 8 is free to partake in the rotation of the commutator 9 and rotor 10,but for only about 1/4. turn. Its movement in both directions is stopped by a fixed stopper 12, which projects in the path of two lugs 13, 14 on the brush-rocker.

A pivoted stopper 15 (hook or the like) is actuated by a spring 17 or by gravity or both so as to catch the brush-rocker 6 and retain it in the starting position (shown in Fig. 2), when the current is shut oil, a hook 16 on the brush-rocker being used for engaging the stopper 15 in the form shown. when the current is let on, the stopper 15 is automatically attracted by one of the magnets 11 so as to release the brush-rocker.

Referring to Fig. 2 when closing the circuit (by means of the switch 67, Figs. 4, 5, 6,) the rotor 10 will first rotate some turns counter-clockwise and thus cause the bell to make a short movement in one direction. The increasing resistance of the bell will soon force the rotor to stop and to rotate clockwise. As the brush-rocker 6 then automatically shifts its position about 90 from the position shown on the drawing (so as to bringing 14 to rest upon the underside of stopper 12), the motor will be able to cause the bell to make a larger movement to the other side and after again having been stopped and returned a still larger movement to the first side and so on until the bell has reached its ordinary amplitude of swinging.

If the motor is correctly proportioned with relation to the weight of the bell or wound with sufficient inner resistance and no great changes of pressure in the circuit are occurring, the device now described is all that is necessary for driving the bell. WVhen the ringing shall cease, the switch 67 must be actuated again so as to shut 011' the' current. The hook 15 thus released from the magnet will catch the hook l6 and lock the brush rocker in the osition shown in Fig. 2.

I will now dcscri e the automatic resistance 1' shown separately in Fig. 3, the use of which, though not always necessary, will involve great advantages. Fastened to the rotating shaft 5 of the motor or adapted to be driven by it is a tubular shaft 51 or the like in which is guided a sliding piece 52 having lugs 58 projecting through longitudinal'slots and pivotally connected to arms 54, ending with weights 55, which by forked links 56 are pivotally connected to the shaft 51. A spring 57 passed into the tubular shaft tends to force the piece 52 outward so as to keep the weights 55 pressed toward the outside of shaft 51. The inner support 58 for the spring may be fastened at different points along a slot 59 so as to adjust the tension of the spring. By means of a link 60 the piece 52 is connected to an arm 62 pivoted at 61 the free end of which slides along a series of contact pieces 63, connected to a series of resistances 64.

In the drawing I have shown a series of twenty-five contact pieces and a series of 12 resistances, thelatter being connected to the first thirteen contact pieces as shown while the twelve last contact pieces are connected to the twelve first contact pieces and thus to e the resistances but in reverse order so that the fourteenth piece connects with the twelfth, the fifteenth with the eleventh, the sixteenth with the tenth and so on. The thirteenth contact piece is connected to the binding screw 66. The other binding screw connects with the contact arm 62 which is insulated from link 60. The parts 62, 63, 64k, 65, 66 are insulated from the frame of the apparatus. By means of the binding screws 65, 66 the apparatus is inserted in the cir cuit.

WVhen the motor stands still and the sliding piece 52 thus is in its outmost aosition, the arm 62 is in contact with the rst contact piece (the outmost to the right) and the current has to pass through the whole resistance series so that only a weak current passes through the motor. The latter thus will run with low speed and the weights 55 will swing out but a short distance from the shaft 51 so as to move the arm 62 to the next contact piece. A part of the resistance being thereby excluded the current increases and the motor gets a greater speed so that the weights are removed farther from the shaft 51 and the arm 62 is pulled farther to the left and the resistance is thus again decreased and the speed of the motor increased. In this way the current increases successively to its normal strength. The arm 62 is then in contact with the intermediate (thirteenth) contact piece and the whole resistance is excluded. If on account of accidentally increased tension the current exceeds the normal strength and the motor thus runs still faster so that the arm 62 reaches the fourteenth or a following contact piece, resistance is again out in automatically so that the current is decreased until the motor runs again with normal speed.
