AUTOMATIC sror inconsistent.

To all whom. it may concern Be it known that I, Josnrn PEDERY, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Automatic Stop Mechanisms, of which the following is a specification.

This invention has reference to automatic mechanisms arranged for use as a stopping means on wire drawing machines, and which i is especially designed for throwing out the wire winding or take up devices in case that the wire becomes tangled on the coil or breaks when passing through the reducing die through which the wire is drawn.

My invention has for its object to provide 1 a mechanism of the general character stated of a simple and economical construction, and in which the several parts are cooperatively so combined that the drawing machine is stopped or shut down automatically, in case the wire strand being drawn becomes tangled-or knotted, or broken.

Another object of my invention is to provide a simple and effective means for stopping or throwing out the wire take up or winding mechanism, and which is automatically set into operation through lever mech- :inism that is arrangedfor being set into action either by reason of the wire tangling or knottiiig before it reaches the reducing die or when the said wire breaks at such die.

lVith other objects in View that will hereinafter appear, my invention consists of the peculiar combination and novel arrange-v ment of the parts hereinafter 'tully explained, specifically pointed out in the apand the shiit'table lever devices that actuate the stopping lever controlled devices, and Fig. 4 is a"similar view of the means for and the wire in pulling out between t Specification of Letters Patent.

lifting the wire take up cone roller out of rotative connection with the driving shaft.

in the drawing, 1 designates a reducing die through which the wire strand, to be reduced, passes to the take up or winding means which in the present showing is acone pulley 8, vertically slidable on the driving shaft 80, provided with a clutch 81 for engaging the cone clutch face 82, of the, pulley 8, it being understood that under normal conditions the cone pulley 8 rotates with the driving shaft 80. 4

Die "1, before referred to, is slidably mounted on the table or frame, and it has a pendent arm 2 provided with an elongated slot 2 that receives the lateral stud 28 m one end of a bell crank lever 28, the other end of which pivotally joins with the upper end of a plunger rod 22 that moves through and is guided in a slotted frame portion 23 and normally rests on the inner end or a lever 20, pivot-ally mounted on a stud 20*, to swing in the vertical plane and with its outer end pivotally connected to the lower end of a lifting lever 19.

- Lifting lever'l9 carries a bifurcated head block 19 at the upper end, in which is journaled a grooved roller 12, which. in my" censtrnction serves as a guide for the wire strand 29, the latter passing through the head block 19 and under the roller 12, which latter, as is clearly-shown in the drawing, is in a plane below that of the reducing die 1, the reasons for which will presently appear, it being understood that the wire 29 that passest-hrough the head block extends from the wire reel.

By reason of cooperative arrangement of the parts so. far described and as shown in the drawing, the operation thereof in case the wire strand 29 becomes tangled on the coil, causes pressure on the guide wheel 1% he said wheel12 and the die 1 littsthe lever it? to the dotted position on Fig. Q, and in consequence swings the lever 30 down to the dotted position, the said downward move mentof which operates the lever mechanism that shifts the wire take pulley out of operative connection with the driving shaft, in the manner presently fully explained.

18 is a spring that is engaged by the lever 20, which is comp-ressed when the lever is swung down as before mentioned and throws the said lever 'up or back to normal when the drawing machine is again set into operative condition. y

When the wire breaks at the die and the 5 normal pull strain on the die 1, in the direction of the arrow X, is thereby released, a spring 27 quickly slides the die 1 forwardly in the direction of'the arrow y, and in doing so, rocks the bell crank lever 28, and since the outer arm 28 of the said lever 28 is swung down it shoves the plunger rod or lever 22, down, to cause it to swing the'lever 20 down for. operating the means that automatically releases the winding cone pulley stood thatthe same operations of the parts, now tobe described, take place under the downward thrust of the lever 20, no matter whether it'is swung down b vertical pull of the lifting lever 19 or the s iding motion of the die;

25 designates a plunger rod that slides in the frame 23, and it is normally projected to its upper position by a spring 23 attached to a collar 24,-.clamped onthe rod 25, and to a guide block 23, of the frame 23,.as shown. Rod 25 is adapted 'to be engaged by and pushed down, by the lever 20 whenever it is moved down to its lowermost position, see

30 dotted lines Fig.2, in either of the ways hereinbefore described. Rod 25'is joined to a bell crank lever 21, mounted on a support 16, and said crank lever is pivotally connected with a linkbar 13 that pivotally joins with guide arms '15, pivoted on a base support 30, whoseupper or free ends engage the sides'of a beam 3, pivotally mounted on a standard 32 that- 'is pivotally supported at the lower end on the base support 30 to swing lengthwise of the machine, whereby to shift the beam 3'longitudinally, and at the same time, permit ofits being vertically tilted, in the manner presently stated, to the dotted position'shown. The pivoted standard 32 and 'the'beam 3 are held to their backward or normal positions, see full lines Fig. 2, by a coiled spring 34. 4 designates-a constantly revolving crank on a driven shaft. 40 and the'said crank, when the beam 3 is shifted forwardly by the link bar 13, engages the beam and tilts it to the dotted position shown.

5 designates a third plunger rod or lever,

5 the lower end of which rides in a bearing 16,

in a support 16*, and its lower end is held on the rear end of the beam 3, so that, as the beam 3 is tilted, the's'aid rod 5 is pushed upward. The upper end of rod 5 is pivotally connected with a rocking lever 6, the forwardend of which rests on the free end 70 of'a iocker frame 7 flexibly hung from the tableor'bed of the machine, and provided with angle arms 71, that carry friction rollers 72, which in turn engage the under face of the flanged end of the cone 8 from the driving shaft, it being underpulley 8 out of \clutched engagement with the drive shaft. Rod 5 has a rack tooth 50 for engaging and interlocking with a bev eled latch tooth 18 on a spring arm pendent from the table.

17 designates a hand lever connected to the spring latch lever for releasin it from the tooth 50, it being understood t at when the mechanism described is actuated to automatically throwthe drawing and winding devices out of operation The operating lever devices which shift the lever 6 are held so that they do not perform their function at this time since the lever 5 is not held out of the position where it would be engaged by the beam 3, it being understood that said devices are restored to their normal or operative position by pushing the lever 17 in the direction of the arrow 2 to return the latch tooth 18 to its locked engagement with the tooth 50.

As is best shown in Fig. 1, the lever 3 is provided with side flanges 90 which form stop members .for engaging inwardly projected studs 91 on the guide arms 15 and which have for their purpose to limit the up-thrust of the lever 3.
