CARD-WIRING MACHINE. a

SPECIFICATION forming part of Letters Patent No. 674,369, dated May 21, 1901.

Application filed September l, 1900. Serial N o. 28,812. (No model.)

To @ZZ whom it may concern.-

Be it known thatI, WALLACE W. FULLER, a citizen of the United States, residing at Charleston, in the county of Charleston and State of South Carolina, have invented new and usefullmprovements in Card-Wiring Machines, of which the following is a specification.

This invention relates to new and useful improvements in card-wiring machines; and its primary object is to provide a simple and durable device formed of but few parts and which will effectively threadl wire through tags, doc., and twist the same.

To this end the invention consists in providing a suitable frame, within one end of which is mounted a vertically-movable tubular plunger, tothe lower end of which is secured a tubular needle. This plunger is provided with mechanism of peculiar construction, whereby when the same moves downward the wire which is passed therethrough .will be carriedtherewith; but the upward movement of said plunger will have no effect upon said wire. Motion is imparted to this plunger from a shaft upon which is mounted a cam of peculiar contour. A pin projects from the face of this cam into an eccentric slot formed within a cam which is mounted in a slide, the upper end thereofA being connected to the end of a pivoted lever, said lever engaging the plunger at its forward end. The cam upon the shaft also operates suitable shearing mechanism, whereby the wire is severed after the same has been inserted through a card. Suitable means are also provided for twisting the wire.

device. Eig. 2 is a longitudinal section therethrough. Fig. 3 is a section on the line o: of Fig. 2. Fig. 4 is an enlarged vertical section through the upper portion of the plunger. Fig. 5 is a bottom plan View of the shearing mechanism. Fig. 6 is an enlarged longitudinal section through the worm. Fig. 7 is a view of a portion of a card, showing the wire therein after the same has been twisted.

The frame of the machine is formed, preferably, of a single casting, which comprises a base 1, a standard2, and a hollow forwardlyprojecting arm 3. This base is provided at its forward end with an upright 4, the upper end of which is provided with a horizontal platform 5, said platform having an inwardlybent inner edge 6, as shown. Astandard 7 extends upward from the base at a point between the front and rear edges thereof and is provided at the top with an aperture 8 for the reception of a worm, which will be hereinafter more fully described. A stud or projection 9 is arranged upon Ithe base at a point adjacent to the standard 7 and receives a sliding rod 10, which is connected at its forward end to a jaw 11, having transversely-extending teeth upon the working face thereof. This jaw is in alinement with a second jaw 12, which extends rearward from the upright 4, heretofore referred to, and is also provided with teeth upon its working face. A coil-spring 13 is mounted upon the rod 7 and is secured at its opposite ends to the stud or projection 9 and to the lower end of a lever 14, which is pivoted to the end of said rod and rocks upon the end of a bracket 15, which is preferably formed with and extends upward from the base. It is obvious that as this spring will have a tendency to contract at all times it will normally hold the jaw 11 in contact` with the fixed jaw 12. The standard 2, aswell as the arm 3, whic extends forward from the upper end thereof, is hollow, and a shaft 16 extends transversely therethrough. A-cam 17 is secured to this shaft, and the front and rear edges thereof project through slots 18, formed within the standard. This cam is provided upon its periphery at proper intervals with projections or shoulders 19 and 20, and a pin or stud 21 extends from opposite faces thereof at a point adjacent to the shoulder 20. One end of this stud is preferably provided with a revoluble sleeve 22 and travels within an eccentric slot 23, formed within a cam 24 of peculiar contour. This slot is formed by inner and outer concentric portions, the inner portion 25 being connected to the outer rim of the cam by IOO means of connecting-strips 26. A circular opening is formed within the inner portion for the reception of the shaft 16, said opening being of sufficient size to permit of an upand-down as well as a rocking movement of the cam upon said shaft.

Extending from the lower edge of the cam 24 is an arm 27, which is slidably mounted within an aperture 28, formed within a rocking pin 29, which pin is journaled at opposite ends within the sides of the standard 2. Extending from the upper edge of the cam 24 is a second arm 30, which is pivoted at its upper end to the short arm of a lever 31. This lever is fulcru med within the arm 3 at a point adjacent to said end and is provided at its free or forward end with a longitudinally-eX tending slot 32. It will be seen that the arm 3 is provided upon its upper and lower surfaces with longitudinally-extending slots 33, whereby the movement of the lever 31 will be unobstructed. The slot 32 of the lever receives a stud 34, which projects from the side of a hollow plunger 35. This plunger slides within a vertical passage 36, which is formed within a head 37, provided at the front end of the arm 3. A tubular needle is detachably secured to the lower end of this plunger, and clutch mechanism of peculiar construction is provided near the upper end thereof. This mechanism, as shown in Fig. 4, comprises a Wedge-shaped slide 39,which is mounted within a recess 40, formed at one side of the passage within the plunger. That edge of the slide which is adjacent to the passage is toothed, as shown, and the inner inclined edge thereof bears upon the inclined face 41 of the recess. A coil spring 42 is seated within the recess and bears upon the lower edge of the wedge 39 and obviously holds the same normally projected into the passage within the plunger. It will be seen, however, that when the plunger moves upward upon the wire it will be forced downward upon the inclined face 41, compressing' the spring 42. This will obviously withdraw the toothed face of the plunger from engagement with the wire. When, however, the movement of the plunger is reversed, these teeth will engage the wire and draw the same downward therewith.

The bottom of the head 37 is provided with a flange 43, at opposite sides of the lower face of which are secured guides 44. These guides support sliding cutting-

blades

45 and 46, to one of which, 45, is secured a forwardly-extending arm 47. This arm is pivoted at its forward end to a lever 48, which is fulcrumed upon one of the guides 44 and engages at its opposite end a stud 49, projecting from the lower face of the sliding blade 46. The blade 45 is formed with a bar 50, which extends rearwardly from the head and is supported by and secured to the upper end of the pivoted lever 14, heretofore referred to. This bar is held in engagement therewith by means of a stud 51, which engages a slot 52, formed within the lever 14. A roller53is journaled within the lever 14 at a point between the ends thereof and normally bears upon the periphery of the cam 17, the same being held in contact therewith by the spring 13, heretofore referred to.

The rear end of the base 1 is provided with an upright 54, having an aperture therein for the reception of a sliding rod 55. This rod is also slidably mounted within the standard 7, heretofore referred to, and is provided at a point adjacent to the cam 17 with a stud or pin 56, which is shown in dotted lines in Figs. 1 and 2. Arms 57 and 5S project upward from this sliding rod, and the forward arm 58 has a downward extension 59, which rides upon the rod 10, before described. A spring 60 incloses this rod and bears at opposite ends upon this extension and upon the projection 9 of the base.' This spring will obviously retain the sliding rod and its arms normally removed from the rear of the frame. Each of the arms 57 is provided at its upper end with an aperture 61, having balls 62 therein, upon each series of which bears a cone 63. This cone is secured to a threaded stem 64, which projects from one end of a worm 65, heretofore mentioned. This stem passes through the aperture 61 and is engaged bya nut 66, which extends into the arm 57 and is provided with a flange which bears upon the face of said arm and limits the inward movement of the nut. Both ends of the worm are mounted in the same manner. A groove 67 is formed within the face of the worm and extends longitudinally from the forward end thereof to a point adjacent to the center. Said groove then encircles the worm a desired n umber of times and terminates in a second longitudinally-emending portion 68, which runs to the rear end thereof. This groove receives a pin 69, which extends thereinto from the standard 7, before referred to. The forward end of the worm is provided with two parallel arms 70, each of which has an aperture 71 therein of sufficient size to receive the needle 38. When the worm is in its normal position, which is shown in Fig. 2, the arms will extend above and below the rear edge of the platform 5 and the apertures therein will be in alinement with the needle 38.

As shown in dotted lines in Fig. 6, the platform 5 is provided with a recess`74, which is in alinement with the needle 3S and permits the same to travel down ward therethrough.

The base 1 is mounted upon suitable guiderods 75, and it will be understood that two or more machines similar in construction to that heretofore described may be arranged upon these rods, so as to permit two or more cards to be wired at the same time. In such case the cams 17 of the machines would all be mounted upon the single shaft 16 and a screw 76 (shown in dotted lines in Fig. 3) would be used for adjusting the machines from or toward each other. To do this, it would be necessary to provide the screw with threads IOO IIO

of varying pitch, the threads of one pitch engaging one machine, while the threads of another pitch engage a vsecond machine. In lieu of this means for adjusting the machines from and toward each other, however, any suitable mechanism may be employed.

When it is desired to wire a card, the plunger is raised into the position shown in Fig. 1 by revolving the cam 17 until the stud 21 thereof has traveled to the lowest portion of the slot 23, thereby forcing the cam 24 downward and raising the slotted end of the lever 31. The edge of the card will be placed under the inwardly-turned edge of the platform and between the arms of the worm. Wire is threaded through the plunger 35 and the needle 3S until the same projects ashort distance from the lower end thereof. The shaft 16 is then revolved, and the pin upon one face of the cam 17 will contact with the projection 56, forcing the same, together with the rod 55, rearward and compressing the spring 60. The pin continuing its travel within the slot 23 will gradually raise the cam 24 and force the plunger and its needle 38 downward. When the needle approaches the limit of its downward movement, the shoulder 19 upon the cam 17 will contact with the roller 53 and force the lever 14 forward upon its fulcrum. This movement, however,- will not be sufficient to bring the edges of the cutting-blades45 and 46 into contact with the needle. The movement will, however, be sufficient to slide the jaw 11 backward, and as the needle continues downward in its movement the end of the wire will be inserted lbetween the jaws. As soon as the projection 19 passes the roller 5.3 the jaws will be sprung together, clamping the wire in position. The pin will then continue in its travel within the slot 23 and will force the cam 24 downward, raising the plunger and its needle and permitting the slide 39 within said plunger to slip over the wire. As soon as the needle has been withdrawn into the head 37 at the limit of the upward movement of thev lever 31 the large shoulder 20 upon the cam will contact with the roller 53 and release the lower end of the wire from the jaws and at the same time force the cutting edges of the

blades

45 and 46 together, severing the wire. Shortly after this operation one of the pins 21 will' contact with the projection 56 upon the slide 55 and force the same rearward. This will obviously draw the worm through the aperture within the standard 7, and as the wire has previously been passed through the openings within the arms 70 said wi re will be carried over the edge of the platform 5 for a distance equal to the length of the groove 68. The worm will then be revolved within the standard 7 by reason of the pin 69, which engages therewith, and after said pin has traveled through the several coils of the groove it will enter the slot 67 and permit the free ends ot' the wire to slip through the openings 71. It is obvious that as the worm is being revolved when the pin is engaging with the coiled groove the two part-s of the wire will be twisted. The card is then removed from the platform and another replaced, and the cam continuing in its revolution will cause the device to repeat the operation heretofore described.

The wire may be fed to the plunger from any suitable source, as a reel. (Not shown.)

It will be understood that the slide 39 within the plunger will firmly graspthe Wire when said plunger is moving downward and will carry the same therewith, but that it will slip over the wire when moving upward and again engage therewith at the limit of th'e upward movement of said plunger.

The device is simple in construction, and as it is constructed of but few parts the same can be cheaply manufactured and is extremely durable in use.
