To @ZZ rofl/077i, 'it wtfty concern:

Be it known that I, FRIEDRICH VVEULE, a citizen of Germany, residing at Bockenemon-the-Harz, Germany, have invented an lmprovemcnt in Bell-Ringing Apparatus, of which the following is a specification.

My invention relates to means for automatically ringing church or alarm bells; and more particularly it consists in an arrangement and combination of mechanism designed to be operated by an electric motor.

One of the advantages of my invention resides in the fact that the ringing' of the bell may be controlled from any convenient point, which may be at a considerable distance from the bell itself, since all that is necessary to start or stop the ringing of the bell is the manipulation of electric switches.

Means are provided, as will hereinafter more particularly appear', to derive the oscillatory movement required for the ringing of the bell from the continuous rotation in one direction of the motor, and provision is made to cushion the impulses delivered to the bell by the motor, such provision comprising what I term a compressed-air coupling.

The various novel features and combinations of my invention will now be more specifically described, reference being had to the accompanying two sheets of drawings,in which the same numerals are used throughout the different views to indicate like parts, and will be iinally pointed out and speciiically stated in the annexed claims.

1n the drawings, Figure 1 represents in side elevation a bell connected to my improved electrically-driven mechanism for ringing the same. Fig. 2 is an end elevation and partial section of said mechanism. Fig. 3 is a detail sectional View 0f one of the clutches. Fig. 4 is a detail sectional view of the automatic means for preventing the amplitude of the swinging movements of the bell from materially increasing, taken on the line 4 4, Fig. 2. Fig. 5 is a section through the compressed-air coupling, taken on the line 5 5, Fig. 2.

ln the iigures, 1 represents an electric motor the armatureshaft of which is operatively connected to a shaft 4 by means of a worm 3 and worm-wheel or other suitable gearing. The shaft 4 carries loosely the drum 18, on which is wound the rope leading' to the bell, as shown in Fig. 1, said drum having formed integral therewith or attached thereto a gear 15.

In Fig. 2 I have shown diagrammatically a circuit and switch 2, by means of which the motor can be started or stopped from any convenient point. The shaft 4 also carries the compressed-air coupling' 38, which has a yielding connection with the drum 18, as will be hereinafter described, the sliding clutch member 35, the pinion 23, and the gear 5, said last three elements being keyed to said shaft 4. Gear 5 meshes wi'th a gear 6, fast on a shaft 7, on which is loosely mounted a gear 9, meshing with gear 15 of the rope-drum 18. Gear 9 has a clutch 8 connected therewith, and keyed to shaft 7 is a sliding clutchsleeve 43, adapted to engage the clutch 8. Said clutch 8 carries a cam or cams 19, with which operate cams 20, formed on the yoke 50, which actuates said sleeve 43. The yoke 5() is pivoted by its shank 21, Fig. 1, to a rod 13, supported on the frame, from which rod an arm 53, carrying a weight 14, projects.

The weight 14 is normally maintained in an elevated position by means of a lever 22, one end of which is connected thereto by a link 47 and the other end of which is normally prevented from rising by a catch 12, .formed on the armature of an electromagnet 10, the circuit of which is controlled by a switch 11, located adjacent to the motor-switch 2.

The pinion 23 meshes with a gear 25, fast on a shaft 24, which carries two cam-

disks

26 and 27, the latter being fast to the shaft and the former being adapted to be clutched thereto by a sliding clutch-sleeve 29. rlhis clutch is operated by a yoke 51, similar to the yoke 50 of the clutch 43, the shank of which is loosely pivoted on the rod 13.

The sleeve 29 is operated, through its yoke 51, to engage the cam-disk 26 by a lever 30, pivoted on a post 63, the opposite ends of said lever lying directly behind the vertical arms of the shanks 21 and 52 of the yokes 50 and 51, respectively. When, therefore, the weight 14 is released to move the sleeve 43 (by means of the yoke 50, shank 21, rod 13, and arm 53) into engagement with the clutch 8 on the gear 9, the sleeve 29 is moved in the opposite direction by means of the yoke 51 and shank 52, with which lcver-30 contacts to engage with the clutch on the cam-disk 2G. The electromagnet 10 only comes into use when the ringing is started, the operation of the mechanism so far described being' as follows:

Closing the switch 2 starts the motor and closing switch 11 releases the weight 14, and

IIO

clutch 43 thereuponengages clutch 8. The drum 18 is therefore rotated by the motor th rough shaft 4, gears 5 and 6, shaft 7,

clutches

43 and 8, gear 9, and gear 15, and the bell is pulled. The cams 19 and 2O come into contact after approximately a half-revolution of gear 9, and sleeve 43 is thereby cammed back out of engagement with clutch 8. This raises weight 14 again, and the switch 11 having been opened immediately after the drum is started said weight is again maintained in its elevated position by the catch 12, a suitable spring, as 54, (see Fig. 2,) being provided t0 hold said catch away from its magnet. Then the clutch-sleeve 43 was slid into engagement with the clutch 8 of gear 9, clutch-sleeve 29 was also slid into engagement with the clutchhub of cam-disk 26 by the action of the lever 30. Shaft 4, through pinion 23 and gear 25, drives shaft 24, and consequently cam-

disks

26 and 27. Cam 31 on the disk 26 acts on roller 32 of lever 34, piveted at 33 (see Fig. 2) to slide clutch 35 into engagement with compressed-air coupling 38. The drum 18, which has been returned by the weight of the bell, is accordingly now again rotated in the same direction as that in which it was first rotated by gear 9. Cam 36 on disk 27 acts on roller 37 to throw lever 34 and ciutch 35 in the opposite direction, and then the weight of the bell returns the drum again. The continued rotation of shaft 24 brings cam 31 round again, and the clutch 35 is thrown in again, and this cycle of operations is repeated as long as the motor continues to run.

There remains to be described the structure of the compressed-air coupling' and the means to prevent the amplitude of the oscillations of the drum 18 from materially increasing.

The coupling' consists of a cup-shaped casing 38, (see Figs. 2 and 5,) mounted loosely on shaft 4 adjacent to the closed end of the drum 18 and having a circular flange engaging a groove in said drum, making a. substantially air-tight joint therewith. The end of said drum is provided with two radial ribs 18, and the casing 38 is provided with two pairs of radial ribs 68, each pair occupying a position intermediate of the ribs 18. Between each rib 18 and one rib 68 of each pair is arranged a coil-spring 39, the space between the other ribs 68 and the ribs 18 forming closed airchambers 69. Vhen, therefore, an impulse is delivered te the casing 38, the first effect is to compress the air in chambers 69, and therefore no objectionable jerk is delivered to the drum and bell. out of engagement, the springs 39 act t0 return the casing 38 to its original position rel-y atively to the drum 18. To provide an adjustment for this coupling, so that the aircushioning effect may be regulated, each chamber 69 is provided with a lug having a longitudinal aperture 4() and lateral passages 42, which latter may be more or less closed Then the clutch 35 is drawn by a cap 41, screw-threaded onto the aforesaid iugs. As repeated impulses of equal force will cause the oscillations of the bell to gradually increase, T have provided automatic means to prevent this, comprising a bracket 44, mounted to slide longitudinally in the lever 34, which bracket carries the rollers 32 and 37. This bracket has a lateral projection, preferably in the form of an antifrictionroller 48, (see Fig. 4,) which when the amplitude of the oscillations of the bell, and consequently also of shaft 24 and cam-disk 26, increases beyond a certain point is acted upon by a cam 28, carried by or attached to said cam-disk 26, the bracket 44 being thereby raised and the rollers 32 and 37 being carried in radially of the cam-

disks

26 and 27, cam 31 of the former disk being cut away en its inner edge, as shown in dotted lines in Fig. 1. The roller 32 is therefore not acted on as soon or even not .at all, and consequently the impulse given to the drum 18 through clutch 35 and coupling 38 has less or no effect. To maintain the bracket 44 when it has been raised by caln 28, it is provided with a springpawl '45, arranged to engage with ratchetteeth 46, formed on lever 34. Cam 36 on disk 27 is so shaped at one end, as shown in dotted lines in Fig. 1, that as it comes around it will strike the free end of the pawl 45, release the same from the ratchet-teeth 46, and permit the bracket 44 to fall toits former position relatively to lever 34.
