My invention relates'to alarm devices for baling presses and operating to indicate to an operator of a press that suflicient material has been fed into the press to form a bale,

and the object of my invention is to provide a device of this character, readily mountable upon a baling press, simple in construction and effective in operation.-

7 Referring to the drawings in which similar numerals indicate identical parts Figure 1 illustrates the application of my device to a baling press; 1

Figure 2 is an enlarged view of my invention showing the parts as set *for operation with part of the bell broken away; 1

Figure 3 is a front elevation of Figure 2 with part of the bell broken away; and, 1

Figures 4, 5, 6 and 7 illustrate the various positions assumed by the tripping lever in operation.

The part of a baling press shown,- to illustrate the application of my invention, is part of abaling chamber 1, of a well known type and constructed of angle steel bars 2, and flat 5 bars 3, and having sides sufficiently open to accommodate theoperation of tying the bale. Part of a finished bale 4c is shown and also part of a bale 5 in process of beingformed, and separating them is the division block ,6

provided with the usual grooves 7 through which the binding wire is fed. 7

My device comprises a support Shaving upper and lower horizontallydisposed parts a and b spaced apart to form a horizontal slot 9'to receive the horizontalflange of the angle frame bar 2 andthe flat bar 3 resting thereon. A bolt 10 secures the support rigidly in place. Extending upwardly from the support, and integral therewith, is an arm 11 the upper end of which isbent, as atf 12, to

form a seat for a bell 13 'rigidlysecured on the seat by a bolt-14 and a nut on the end of the bolt. A similar arm 16 extends upwardly from the support parallel withthe' arm '11 and of lesser length, and between the arms Hand 16 a clapper lZis pivotally supported on a bolt 18 which passes through'both arms and the clapper and is securedby a nut19.

A bolt 20 extendsfrom the closed end of'the slot 9 througha suitable opening" in a boss 21 integral with the support 8, and on this bolt a lever 22 is pivotally mounted, intermediate its ends, and held thereon by a nut 23. The lever is bent below its pivot and from the bend extends downwardly parallel with the side'of the press. Pivotally mounted on a bolt 24 in the upper end "of the lever 22 is a swinging dog 25 having-its upper end beveled downwardly toward the clapper l7 and in constant contact therewith. The dog 25 is elongated below its pivot into a narrow part 26 which is in normal contact-with the nut 23 on'the bolt 20.- A coiled spring 27 has one end attached to the end of the bolt 20 and the opposite end attached to an end of theclapper 17. The striking end of the clapper 17 projects slightly beyond thebell 13, as shown in Figure 3, and between that end of the clapper and the'pivot thereof is a bracket 28 riveted to the side of the clapper. A bolt 30 is adjustablyheld in a threaded aperture 31 in the support 8 and a boss 32 thereon and is held in any adjustment by a jam nut 33. A coiled spring 34 on the bolt 30 exerts its expansive force between the head of the bolt and a horizontal part 35 of the bracket 28 through which the bolt loosely extends.

Ba ling presses are provided with a device for retardingthe progress of a completed bale on its way to the end of the press where it is 1 e0 7 slowly longitudinally and takes up the slack v in the" wire with which the bale has been bound, as shown in dotted linesin'Figure 1.

The lower part of the lever 22 is close to the I bale so that theupper wire 36, as it is placed, encloses thelower part of the lever, as shown in Figure 1, and is tight enough to swin the lever in-the direction of movement of the ale. As th'e-lever swings onits pivot 20 the dog 25 operates against the adj acent endof the clapper 17 and rocks the latter on its pivot 18 on the arms 11 and 16 on the support 8. The clapper rides up on the beveled end of the dog 25 and against the expansion ofthe spring 27 until the clapper has been rocked to its limit, the lever 22 and the dog and clapper then being in the position as shown in Figure 5. Further movement of the lever disengages the dog and the clapper, so that the latter, by contraction of the spring 27 is instantly rocked on its pivot 18 causing the opposite end of the clapper to strike the bell 13 with suflicient force to ring and so warn the operator of the press that suflicient material has been fed into the baling chamber to form a bale as 5.

It will be noted that the action of the spring 27 is contractile, and the action of the spring 34 is expansive, so that the action of both springs is to hold the clapper 17 substantially horizontal and free from contact with the bell 13 until it is actuated by operation of the lever 22 and the dog 25. When the clapper 17 is rocked by swinging motion of the lever the spring 27 forcibly expands by the rise of that end of the lever to which it is attached, consequently its contractile power is materially increased, at the same time the normal expansive power of the spring 84 is very much decreased, it therefore follows that with the instant release of the clapper from the dog, the former, by the sudden contraction of the spring 27 snaps back with sufiicient force to cause its free end to strike the bell, then by the combined action of both springs the clapper is restored to its normal inoperative position.

After the dog 25 and clapper are disengaged the parts are as shown in Figure 6, the lever however is still being operated upon by the movement of the bale 4, the upper wire 36, holding the lever and actuating it, has been drawn taut. Dotted lines, in Figure 1, of the end of the lever indicate the limit of its movement by the bale. At this point the lever is free again and as it is loose on its pivot gravity swings it toward its normal position. As shown in Figure 6 the dog 25 has passed the clapper 17 and the latter is again in readiness for actuation; the dog however is on the side of the clapper opposite from its operative position, and its return to normal position to actuate the clapper is accomplished by the lever swinging a sufilcient distance to cause the dog to rock on its pivot on the lever so as to pass the clapper, as shown in Figure 7, after which movement the lever and the dog return to the normal operative position shown in Figures 1 to 4 inclusive.

What I claim is- 1. In an alarm device for baling presses adapted to be mounted on a press, the combination of a support, a bell on the support, a clapper pivotally mounted intermediate its ends on the support, a lever pivotally mounted intermediate its ends on the support and swingable by longitudinal movement of a bale, a dog pivotally supported intermediate its ends on the lever and operating to rock the clapper when the lever is swung a predetermined distance and to instantly release the clapper by continued swing of the lever whereby the clapper is caused to ring the bell.

In an alarm device for baling presses adapted to be mounted on a press, the combi nation of a support, a bell on the support, a clapper pivotally mounted intermediate its length on the support beneath the bell and extending transversely of the bell, a lever pivotally mounted intermediate its'ends on the support and swingable by longitudinal movement of a bale, a dog pivotally supported on the lever above the pivot of the latter and having its upper end inclined and in contact with the clapper, said inclined end adapted to rock the clapper as the lever is swung a predetermined distance and to instantly release the clapper by continued swing of the lever whereby the clapper operates to ring the bell.

3. In an alarm device for baling presses adapted to be mounted on a press, the combination of a support, a bell on the support, a horizontally disposed clapper located beneath the bell transversely thereof and pivotally mounted intermediate its ends on the support, a lever pivotally mounted intermediate its ends on the support and adapted to be swung by longitudinal movement of a bale, a dog pivotally mounted intermediate its ends on the upper end of the lever and having its end inclined transversely of the clapper and normally in operative contact with the under side thereof, said inclined end adapted to rock the clapper as the lever is swung a predetermined distance and to pass by and suddenly release said clapper by continued swing of the lever whereby the clapper operates to ring the bell.
