SPECIFICATION forming part of Letters Patent No. 435,285, dated August 26, 1890.

Application filed December 23,1889. Serial No. 334,740. (No model.)

have invented a certain new and useful Improvement in Wire-Straighteners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improved device for straightening and cutting wire; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Fig. XVI is a section taken on lineXVI XVI of Fig. XV. Fig. XVII is an edge view of the lever 66.

Referring to the drawings, 1 represents a suitable bed-plate 'or base, upon which rest standards 2, 8, 4, and 5.

6 represents an operating-shaft journaled in the standards 2, 3, 4, and 5, and upon which is a driving-pulley carrying a belt 7.

8 represents a flier journaled on the upper 7 ends of the standards 4 5 by means of boxes 9. The wire to be straightened passes through the flier from a guide 10. (See Figs. Iand II.)

and are located on shafts 20 and 21.

The construction of the flier is represented in Figs. IV, V, and VI. It is provided with end journals 11, (see Fig.'IV,) fitting in the boxes 9, and which have perforations 12 and and open center 13, through which the wire passes from the holder 10.

14. represents straightening-dies located in openings or sockets 15, extending transversely through the flier.

16 represents set-screws by which the dies may be individually adjusted in or out. Each die has an inclined bearing-surface 17, (shown plainly inFigs. V, VI, and VII,) and against which the wire bears as it passes through the flier. I have shown four of these dies, and they are so placed that their inclined bearingsurfaces 17 will be presented alternately in opposite directions, as plainly shown in Fig. IV. I am of course aware that adjustable straightening-dies in this class of machines, broadly considered, are not new. My invention, so far as it relates to this part of the machine, consists in providing the dies with the inclined surfaces 17 so that by adjusting the dies theirbearing-surfaces for the wire are moved not only inward or outward, but also upward or downward, according to the direction in which the dies are inoved-that is to say, by moving the die shown in Fig. V, for instance, inward, its bearing-surface for the wire is moved both inwardly and upwardly, and by shifting the die in the other direction this bearing-surface is moved both outwardly and downwardly, and thusIam enabled,with the use of dies which are all arranged parallel, to get the same result that would be obtained' by dies arranged at right angles to each other, resulting materially both in the cheapness and usefulness of the machine. As the wire leaves the flier, it passes between feed-rollers 18 19. (See Figs. XIII and XIV.) These rollers are grooved to receive the wire The shafts are journaled in boxes 22 and 23, which are held adjustably in a frame 24.. The frame 2. is provided with lugs 25, (see Figs. I and XIV,) extending in a direction away from the feed-rollers 18 and 19. These lugs form the j ournal-bearingof ashaf t 26, and with the shaft 26 form a pivot for the shafts 20 and 21, the boxes 22 and 23 .of the shafts having perfo- IOO rated extensions 27, through which the shaft 26 also passes. The frame 24 is provided with upper set-screws 28 and lower set-screws 29, and it will be observed that by tightening on these screws the feed-rollers 18 19 will be forced toward each other to increase their tension on the wire, and by loosening on the set-screws the friction between the rollers and the wire will be diminished. I am thus with a very simple contrivance enabled to regulate the size of the opening between the feed-rollers at will.

On the shaft 26 is a worm 30, (see Fig. 11,) and on the outer ends'of the shafts 20 and 21 are wheels 31, which engage the worm 30. The shaft 26 is also provided with a pulley 32, to receive a belt 33, which passes also around a pulley 34 on the shaft 6. It will thus be seen that the feed-rollers 18 19 will be operated from the shaft 6, and that the adjustment of them, as stated, will not interfere with their driving mechanism. From the feed -rollers the wire passes into and through a cutting-die 35, located in the upper end of the standard 3. This die is shown plainly in Fig. VIII. It is held in place by a set-screw 36.

37 (see Figs. III and VIII) represents a knife or cutter formed on the end of .a lever 39, which is pivoted at 40 to the standard 3. 41 represents a plate screwed or bolted to the standard 3, and between which and the standard the knife 37 and the upper end of the lever 39 fits. This plate holds the knife firmly against the face of the standard and against the end of the cutting-die 35. The lever 39 extends downwardly to or past a shaft 6. On the shaft 6 is a loose collar 42, carrying a cam 43, which at the proper time bears against the lower end of the lever 39, and by forcing this end of the lever outwardly moves the knife 37 in a downward direction, causing it to traverse the opening of the cutting-die 35 to sever the wire. When the cam leaves the lever, the latter, with the knife,of course, is restored to its normal position by a spring 44. The collar 42 is operated intermittently, as hereinafter explained. Leaving the cutting-die the wire passes into a receiving-tube 45, supported on the upper end of the standard 2 and on the upper end of a standard 46. (See Fig. II.) In this tube is located a rod 47. (See Figs. Iand IX,) On this rod, beyond the end of the tube 45, is a collar 48, held adj ustably to the rods by means of a set-screw 49. Now itwill be seen that when the Wire passing through the receiving-tube strikes the inner end of the rod 47 the latter will be forced outwardly, and in doing so carries the collar 48 and set-screw 49 in the direction in which the wire is moving.

The outeriend of the set-screw 49 is connected by means of arod 50 to the upper end of a bell-crank lever 51, (see Fig. II,) which is pivoted at 52 to the standard 2. The lower end or arm of the bell-crank lever 51 is connected by means of a link 53 to a lever 54,

(see Fig. III,) the connection being. made to the lever 54 at 5 5. The lever 54 is pivoted at 56 to the standard 3, and it is held in its lower or normal position by means of a spring 57, and when in its lower or normal dog 59 is then thrust forward by the spring. 60 into engagement with the teeth of the clutch 61, which causes the collar 42 to be revolved with the shaft and causes the cam 43 to come against the lever 39, as described, and produces the cutting of the wire. As soon as the wire is cutofi, the portion of it within the receiving-tube 45 is discharged by the opening of the tube, which, as shown in Figs. XI and XII, is provided with a remov-" able side 62. This side is capable of being moved from the position shown in Fig. XI to the position shown in Fig. XII, and when it is thus moved the wire drops freely and automatically from the tube. It is thus moved by being supported on a rock-shaft 63, journaled in the upper ends of the standards 2 and 46, and to which the side 62 is connected by arms 64. After the wire is cut off, as stated, the shaft 63 is rocked to open the tube 45 by means of a cam 65 on the collar 42, (see Fig. XVI,) which, before the collar ceases to turn, comes against a lever 66, pivoted at 67, and connected at its free end by means of a rod 68 and crank 69 to the rockshaft 63. (See Fig. II.) Thus after the wire is cut off the shaft 63 is rocked, and the side 62 of the tube 45 drops down,.allowing the wire which has been straightened and severed to fall from the receiving-tube. As soon as the cam 65 leaves the lever 66, the shaft 63 is moved back to its normal position by'a spring 70, (see Figs. I and II,) and the portion of the wire which was contained in the tube and which produced the movement of the rod 47 and its accompanying parts having dropped out, it will be seen that under the influence of the spring 57 the lever 54 and the rod 47 will be returned to their normal positions. The collar 42 has not yet made a complete revolution, and before it does the lever 54 is thrust back to its normal position, and the head 58 of the dog 59 comes against an incline 71 on the lever 54, which causes the dog to be forced inward against the pressure of the spring 60 and out of engagement with the clutch 61, and thus the collar 42 is automatically disengagedfrom the shaft 6, which revolves continuously.

To prevent the collar 42 from being carried around by its momentum after the dog 59 is disengagedfrom the collar 61, I form a cir cumferential groove 72 therein and pack it with a rubber or other suitable ring, upon which bears friction bars or plates 73, (see Figs. XV and XVL) which are supported by lugsor projections 74 on the standard 2. (See Fig. II.) These bars are connected by bolts 75, (see Fig. XVI,) and it will be seen that by tightening on the nuts of these bolts the bars will be forced toward each other, thus tightening in the groove 7 2 of the collar 42 and producing the required friction to prevent the collar 42 from turning under the momentum imparted to it by its connection with the shaft 6. p

An edge view of the lever 66 is shown in Fig. XVII.

A machine thus constructed is entirely automatic in its operations, is cheap and durable, and is not liable to get out of order.
