WIRE-MEASURING DEVICE.

Application filed Gctober 28, 1915.

To all whom it may concern:

Be it known that l, LEONARD llnannn, a citizen of the llnited States, residing at Ashland, in the county of Boyd and State of Kentucky, have invented certain new and useful Improvements in l/Vire-lvleasuring Devices, of which the following is a specification.

My invention relates to a wire measuring device to be used in connection with wire making machinery to serve as a convenience in positively determining the uniform length or weight of wire to be wound in reels when given the weight per unit of a given size wire either by calculation or by experiment. The weight of a reel of this wire may be very readily calculated when it is known what length of wire is in this reel. This Wire is usually sold by weight, since the easiest method of measuring it in feet or in rods is by weight and my inven tion is, therefore, directed to the provision of mechanism whereby the driving power is automatically stopped when a predetermined length of wire has been passed through the measuring device. In this way, I am assured of the correct weights of each succeeding spool of wire without going through the operation of weighing each one of these spools individually.

The mechanism for carrying forth this end is shown in the accompanying sheets of drawings, in which similar characters of reference designate corresponding parts, and in which:

Figure 1 is an end elevation of my wire measuring device, 3

Fig. 2 is a side elevation of the structure shown in Fig. 1 looking from the left,

Fig. 3 is a top plan view of a portion of the structure shown in Fig. 2, and,

Fig. 4; is an end View of a portion of the structure shown to the left of Fig. 2.

In these several views, the framework of a portion of the wire making machine proper is shown at 1 and this portion of the supporting frame carries an attachment in the form of a measuring device comprising a supporting plate designated 2, which lat- Specificaticn of Letters Patent.

ter is held in position thereon by means of the screws shown at 'iown rd the left of this plate 2 as shown in Fig. 2, is calim? a supporting bracket etalso held in position by means of the screws 3, the iqistandiug leg of this bracket being designed to support a yoke 5 by means of too screws (3 and within this yoke there is rotatably mounted a disk or measuring wheel 7 haw ing a groove 8 in its periphery. Cooperating with this disk is a friction wheel, 9 mounted upon a shaft '10 rotatably journaled in the slide bearings 1.1, these slide bearings being mounted within. the slots 1'12 formed in the outstanding legs of the yoke 5. In order to force the friction wheel into engagement with the measuring wheel to thereby hold the wire in gripping Contact with the disk 7, I have provided the slotted ends of each of the legs of the yoke 5 with vith a tie plate 13 through which adjusting bolts 14: pass. Each of these bolts bears against the underside of a spring 15 whichwill in turn bear upon the undersides of the bearings 11. it will be understood that the wire passing to the wire machine proper is pulled by it between the wheels and 9 to turn them by frictional engagement as is illustrated in Fig. 1. The wheel 7 is carried by the shaft 16 which is journzned in the legs of the yoke and also in the lwaring portion 17 at the upper end of the bracket 4. At its extreme outer end this shaft carries a pinion 18 designed to co operate with a gear 19, which gear is mounted upon the shaft shown at 20. This shaft is journaled at one end in the bracket 1- aud at its opposite end in the bearin'r port 21. At its opposite end this sln. also carries a pinion 22-, which iinion meshes with a gear 23 mounted upon the shaft 24. This shaft 2a is rotatably supported in the bearing members and 26 and is further provided with a drum having a spiral groove formed in its periphery and a collar 28 rigidly held in con-- nection with the shaft by means of the adjusting screw or set screw 29. A cable 30 of proper length is secured at one end to [ill the drum 27 and is designed to be wound about the same to follow the convolutions of the spiral cut therein, while its opposite end is free and adjustably carries a stop collar 31 by means of a tightening bolt 32 cooperating with an internal washer 33. A lever 34: is pivoted intermediate its ends to a pair of depending ears 35 and is further bent at right angles at one end and slotted as is shown at 36 in Fig. 3, the cable 30 being designed to pass through this slotted opening. At its opposite end this lever 3 is pivotally connected with a dog 37 slidably operating through a lug 38 formed on the underside of the plate 2, the dog 37 projecting above the upper surface of the plate, as is shown more clearly in Fig. 1. This end of the dog is designed to cooperate with a trip lever 39 pivoted intermediate its ends by means of the bolt shown at 40. One end of this trip lever is designed to cooperate with the dog, while the other end is designed to cooperate with the lever 4.1 which is the lever which controls the driving power to the machine proper. The lower end of this lever may be connected to directly operate belt shifting mechanism on tight and loose pulleys, or it may be con nected with an electrical regulating apparatus, or any other that may be desired. This lever is drawn toward the right, .as shown in Fig. 1, by means of the spring 42 to effect this stoppage of power and, therefore, as soon as the collar 31 has moved the lever 34: a distance suflicient to cause a withdrawal of the dog 37 to permit the escape of the trip lever 39, the power will be automatically stopped.

It will thus be seen that by adjusting the collar 31 to the correct position upon the cable 30, the machine will be automatically stopped each time a proper length of wire has passed through it, which length will bear a direct ratio to the length of the cable from its secured end to the stop collar 31. The length of this wire is, of course, governed by the number of revolutions of the measuring wheel 7, but because of the great reduction effected by the train of gearing, a slight shift of the stop collar 31 on the cable 30 will mean a considerable length of wire through the machine as a whole. 7

In order to start the machine at a given point after it has already measured one or more lengths of wire, I have provided the collar 28 with an indicating finger l3 designed to play over a plate 44 carried by the upper end of the bearing support 25. By means of this indicator finger, the operator is assured of starting the machine at the proper point by properly locating the finger with respect to the plate 44. Thus, when starting, the cable may be practically completely unwound so that the indicator finger registers with the proper graduation on the scale shown. on the plate 44. The wire is then drawn between the wheels 7 and 9 by the wire working machine proper and the frictional engagement of this wire with the wheel 7 causes its rotation, which rotation is in turn transmitted through the train of gearing to the drum 27. Continued rotation of this drum causes a winding of the cable until the stop collar 31 comes into contact with the pivoted lever 34:. A slight additional movement will trip this lever to retract the dog 37, whichreleases the trip lever 39. It will be noted that the dog 37 bears on one end of this trip lever, while the power controlling lever 41 bears on the other. This power controlling lever is also attached to the spring 42 and, therefore,the withdrawal of the dog 37 causes the power lever to shift under the influence of the spring 42 to automatically shut off the power to the wire working machine.
