Definitions

  • This invention relates to an apparatus for inserting and withdrawing or extracting tacks and particularly those having relatively short prongs and iiat heads, and especially those known as thumb tacks.
  • 1t is an object of the invention to provide means aording stacking or disposing a plurality of the tacks in superposed relation for the successive insertion of the tacks into suitable penetrable material or surfaces.
  • FIG. 1 is a front elevation of the device, with the lower portion of the same in section, showing the first step in the act of extracting a previously-inserted tack;
  • Fig. 2 is a vertical sectional view through the device, showing the tack extracted and elevated in position within the device in readiness for re-insertion;
  • Fig. 3 is a view, somewhat similar to Fig. 1, showing the device with its parts in position for the removal of the lowermost tack in the magazine and its insertion;
  • Fig. 4 is a view similar to Fig. 3 but .showing the tack in the process of being inserted;
  • Fig. 5 shows the device in the position in which it appears after having inserted the tack
  • Fig. 6 is a sectional view, taken substantially on the line 5 6 of Fig. 5 and looking in the direction of the arrows;
  • Fig. '7 is a sectional view, taken substantially on the line l-'I of Fig. 5, and looking in the direction of the arrows;
  • Fig. 8 is a sectional view taken substantially on the line B-B of Fig. 5, looking in the direction of the arrows.
  • I indicates the magazine for holding a plurality of the'thumb tacks 2 in superimposed or stacked relation, and with their prongs 2b directed downwardly.
  • Said magazine is inthe form of a tube or cylinder constituting a casing open atthe top and bottom.
  • the internal diameter of the magazine I is such as to accommodate the heads of the tacks and vertically guide the same.
  • the magazine or casing I is provided with three leaf springs i equally'spaced around the circumference and formed with inward'protuberances 32 near their lower ends to engage under the heads of the stacks to retain the tacks in the magazine.
  • the lower open end of the magazine is also provided in its side wall with three longitudinally-extending slots 3 through which three pivotally mounted jaws Ill are moved.
  • a cup-shaped follower Ib Located within the tubular magazine I is a cup-shaped follower Ib, which is normally urged against the stack of tacks 2 in the magazine by means of a coil spring Ia, located within the magazine I and having one end disposed against the follower Ib and its other end contacting the closed end 5a of a housing or handle 5 Which fits around the tubular magazine I.
  • the tacks 2 are preferably those which are provided with at least three prongs 2b dependent from the head of the tack. This type of tack permits stacking of a number of the tacks within the magazine, with their points directed downwardly, as clearly seen in the drawings.
  • a ring 6 Surrounding the outside of the magazine I and rotatably mounted thereon adjacent to the lower open end of the magazine, is a ring 6 which is movable axially relative to the magazine, and said ring is provided with three slots 30 in its wall spaced equally around its circumference and in registry with the three slots 3 in the magazine I. Mounted vbetween the sides of each of the slots 30 is one of the jaws I0, each jaw being pivotal on a pivot pin Id. These jaws operate to both insert and extract the thumb tacks2 in a manner to be described. To enable the jaws to extract the tacks, each ofthe jaws is provided with aclaw-shaped or pointed end Illa, and with a rounded under surface Ib.
  • a ring I2 located above the ring 6, and said ring I2 is also slidable in an axial direction on the magazine I and within the handle or housing 5.
  • the ring I2 is under pressure of a coil spring II which surrounds the outside of the magazine I and holds the ring I2 against the ring 6.
  • the ring I2 is provided with a spiral slot SI into which a radially-projecting screw I3 on the magazine I projects.
  • the outside shape of the ring I2 is a hexagonal and the same fits within the housing or handle 5 which is internally shaped in hexagonal form to thus conform to the exterior shape of the ring I2 and thereby prevent rotative movement of the ring I2 within the housing 5.
  • the housing or handle 5 is provided with an attached cylindrical sleeve l, formed at its lower end with a bead 8 which is adapted for engagement with the surfaces Ilc of the jaws I during the operation of the device.
  • the engagement between the bead S and the surfaces IIlc of the jaws also limits the extent to which the ring can be urged out of the lower end of the sleeve I (as shown in Fig. 5).
  • the jaws I0 are disposed with their pointed ends Illa. just entering the slots 3 in the wall of the magazine I, or in the position shown in Figs. 3 and 5.
  • the device When it is desired to insert a tack, the device is held in the hands, with the lingers of one hand gripping the protruding portion of the ring 6 between the jaws I0, while the fingers of the other hand engage the housing 5 and turn it in a counterclockwise direction as viewed from the top end 5a of the housing, as far as it will go.
  • This relative movement between the housing or handle 5 and the ring S will cause the magazine I to have its lower end extended out beyond the end of the ring 6, to the extent seen in Fig. 3.
  • This projecting movement of the magazine I is attained through the travel of the screw I3 in the spiral slot 3
  • thumb tacks can be successively applied to any suitable penetrable material and can also be withdrawn, and when so withdrawn will be automatically replaced in or restored to the magazine for future use.
  • the thumb tacks are forced into inserted position and drawn out by direct and even pressure so that, as a result bending of the prongs will not occur and the tacks will not be wasted but can be re-used repeatedly.
  • a device for inserting and extracting tacks comprising a magazine in the form of a casing holding a stack of headed tacks, the casing having an open end through which the tacks are successively driven, a housing extending over the casing and axially movable relative to the casing, means operable on rotative movement of the housing in one direction to extend the open end of the casing out of one end of the housing and operable to retract the casing when the housing is rotated in the opposite direction, pivoted jaws arranged adjacent the open end of the casing, means on the housing to swing said jaws toward one another and in advance of the lowermost tack in the stack while the casing is in retracted position to remove a driven tack and to swing the jaws toward one another when the casing is in extended position to thereby cause said jaws to engage over the head of the lowermost tack in the stack and drive the same.
  • a device for inserting tacks into a penetrable surface comprising a magazine in the form of a tubular casing for holding a stack of headed tacks and having an open end, a springurged follower in the casing for application against the top oi said stack of tacks and tending to urge the tacks toward the open end of the casing, spring means disposed adjacent the open end of the casing for normally preventing emergence of the tacks therefrom, the casing being slotted at its open end, a ring member tted around the casing adjacent to its open end and carrying a plurality of pivoted .jaws movable through the slots in the casing toward the longitudinal axis of the casing, a housing mounted over the casing and movable axially thereof, means operable on relative rotative movement of the casing and housing with respect to one another for advancing the open end of the casing beyond an end of the yhousing to thereby locate the lowermost tack of the stack
