Definitions

  • This invention relates to machines for inserting such fastenings as nails and especially those in which the nails are driven for attaching heels to shoes.
  • the head cannot readily accommodate itself to this movement because it is held against outward displacement by the outwardly and upwardly inclined surface of the driver.
  • the shank is therefore heavily bent, throwing upon the heel near the curved portion of the nail a strain which has a splitting effect.
  • the nail-head wears the inner side of the wall and changes its form.
  • the pressure applied by the heel-engaging abutment should be sufiicient to hold the work firmly down to the jack-top, it should not be such as to crush the heel or wrinkle its covering.
  • I provide a nail-driver or each of a plurality of such drivers, with means contacting with a nail to be driven for normally separating from the nail-driving surfacethe head of said nail. Then, if dirt gathers upon the end of the driver, it may be within the space produced by this separation, leaving the nail-head free to take its desired position. To avoid interference with the driving of the nail, this separation from the driver-end is caused by a yieldable portion thereof, as a spring-plunger, and to insure the inclination of the nail in the definite, chosen direction, this portion is located at one side of the driver-axis.
  • the separating means or spring-plunger is preferably at the opposite side of the driver-axis from the axis of the jack, with its end lying normally outside the nailengaging surface of the driver, so the invariable toeing-in ,of the nail is obtained.
  • the driverend need not be inclined downwardly and inwardly but may be square, or even inclined downwardly and outwardly. When thus formed, the driver will fully sink the nail-head. Since the spring-plunger offers no material resistance to the outward movementof the head of the nail during its driving, this is left free to shift laterally away from the inner side of the passage, tending to aline itself with the point.
  • a sleeve is movable in each driver-passage, the end of this sleeve being held at all times outside the work-supporting surface of the jack by a spring.
  • the sleeve is depressed upon application of the work, and then, if there is insuflicient clamping pressure to hold the insole upon the jack-top, the sleeve will follow it as it moves away and will offer uninterrupted lateral support to the nail.
  • the upper extremity ofthe sleeve furnishes about the opening of the driver-passage a barrier against the entrance of dirt. There may be upon the upper edge of the sleeve a reduced edge, which by its engagement with the insole will prevent the shoe from slipping upon the jack-top when clamping pressure is applied.
  • Fig. 1 is a central, vertical section through a jack in which the invention is embodied, with a co-operating pressure-abutment in side elevation;
  • Fig. 2 an enlarged, sectional detail through the driver and its associated sleeve
  • Fig. 3 a top, plan view of the jack
  • FIGs. 4, 5 and 6 broken, sectional details showing, together with Fig. 1, successive steps in the insertion of a nail by a square-ended driver, while Figs. 7 and 8 are similar views with a driver having a downwardly and outwardly inclined end.
  • a work-supporting jack J including a hollow body Ill with an upper section l2 carrying a top-plate I4.
  • the jack is mounted upon an unillustrated frame, on which is movable toward and from the work-supporting surface [5 of the jack the customary abutment P arranged to force a heel H against the heel-seat of a shoe S resting upon the jack-top.
  • Reciprocating vertically in the jack is a plunger l6 having at its upper end a plate IS in which is secured a gang of drivers 20. These drivers operate in passages 22 extending through the section l2 of the jack and through the top-plate l4.
  • Each driver has at its upper extremity, in the arrangement now being considered, a nail-engaging surface 24 substantially at right-angles to the axis. Extending from this surface along the driver, outside the axis thereof with respect to the axis of the jack, is a passage 26 in which is movable a plunger 28. The lower extremity of the plunger is reduced at 30, furnishing a shank about which is secured, as by soldering, a helical spring 32. The length of the plunger and spring is such that normally the upper extremity of said plunger, when the spring is bottomed in the passage, lies'above the surface 24 of the jack, where it has a conical or pointed end 34.
  • each jack-passage 22 is preferably of substantially greater diameter than the driver 20, and in the intermediate space is a sleeve 36 by which the driver is guided in its nail-inserting reciprocation.
  • the sleeve has a flange 38, which is forced against a shoulder 40 upon the jack-top by a helical spring 42 interposed between the sleeve and the upper face of the jack-section I 2, The flange and spring lie in an enlarged portion 44 of the driver-passage.
  • the upper end of the sleeve 36 lies above the surface I5 of the jack-top, where it is shown as provided with a downwardly and inwardly beveled surface, furnishing a sharp circumferential edge 46.
  • the edge 46 still remains somewhat above the surface l5 of the jack forced into the insole of the supported shoe. It therefore slightly penetrates the surface and holds the work against lateral displacement. Since the upper portion of the sleeve is always above the jack-top, it bars the entrance to the driverpassage of dirt which might clog the plunger 28.
  • Fig. 1 shows a shoe S, having a heel I-I applied to its heel-seat, in place upon the jack J and clamped by the abutment P for the nail-inserting operation.
  • the sleeve 36 will have been depressed by the contact of the insole of the shoe, but the edge 46 still remains sufficiently above the surface l5 to hold the shoe against displacement. If dirt has entered the driver-passage, this will usually be in such quantities that it will lie well below the nail-supporting point of the plunger 28, so the position of the nail will be unaffected. But much of the foreign matter which may have fallen upon the surface l5 of the jack will be kept out of the passage by the elevated end of the sleeve.
  • the outer surface of the nail-head may be caused to conform closely to the surface of the insole, even if this is deeply concaved. This is effected by inclining the nail-engaging surface of the driver 20 downwardly and outwardly from the axis of the jack, as shown at 50 in Figs. '7 and 8. The nail is inclined by the plunger 28 and inserted by the driver 20 as before (Fig. '7).
  • a nail-driver provided with means contacting with a nail to be driven for normally separating from its driving surface the head of said nail.
  • a nail-driver having at its end a yieldable portion for engagement in the passage with a nail to be driven.
  • a nail-driver having at its end a yieldable portion located at one side of the driver-axis and upon which the head of a nail to be driven may rest.
  • a nail-driver having at its nail-engaging surface a yieldable portion located at one side of the driver-axis for contact with a nail, the nail-engaging surface of the driver being inclined downwardly toward the yieldable portion from the other side of the axis from said portion.
  • a nailing machine a Work-support, and a nail-driver movable therein and provided at its nail-engaging surface with a spring-plunger situated at the opposite side of the driver-axis from the axis of the work-support.
  • a nailing machine a work-support, and a nail-driver movable therein and provided at its end with a spring-plunger situated at the opposite side of the driver-axis from the axis of the work-support and having a conical nail-engaging portion.

  • a jack In a heel-attaching machine, a jack, a driver movable in the jack and provided with a longitudinal passage opening through its nail-engaging end and situated at the opposite side of the axis of the driver from the axis of the jack, and a spring-plunger movable in the passage and having its end lying normally outside said passa e.

  • a nail-driver provided with a longitudinal passage, a nail-engaging member having a reduced end-portion, and a spring secured about the end-portion, the spring contacting with the inner end of the driver-passage and the nail-engaging member normally extending outside the passage.
