, 1 Y This invention relates to a thumb tack extrao tor, and more particularly to a novel thumb-tackextracting device having provision for removing a thumb tack or the like and means for'restrain- "ing the removed tack in "a container.'

4 It is an object of this invention to provide'a thumb-tack-extracting device of the kind to be more particularly described hereinafter, having a receptacle for" containing thumb tacks before application for use and for collecting thumb tacks immediately upon removal from engagement with a board or the like. I

Still another object of this invention is to pro- ;vide a device of this kind-Which is 'formed'as a handy manual tool for both pressing thumb tacks into engagement with a board or the like and operable also as a hand tool for readily removing thethumb tacks; l

' A further object of this "invention "is to provide a combined thumb-tack-applying and removing "tool which is readily operable-byone hand of a 'user for pressing the'tack into a selected tackreceiving' work piece and also ior removing the tacks by manipulation of one handofthe user, thus preventing the customary use and breakage of fingernails or the necessity of separate driving and removing tools. With "the use of thistool in removing a thumb tack,- the tack is immediately confined within the collecting receptacle as it' is drawn from the member within which it had been penetratingly engaged. 7

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed'in the drawings, and specification, and then more' particularly pointed 'out'inthe appended claims.

In the drawings:

Figure 1 is a side elevation of a thumb tack tool constructed according to an embodiment ofmy invention, shown in its use as a hammer for'driving a thumb tack into a work piece;

Figure 2 is a top plan view; v Figure 3 is a side elevation, partly broken away and partly in section;

Figure 4 is a front elevation; partly broken away and partly in section; Figure 5 is a fragmentary longitudinal section showing, in detail, the hinged connection of the spring-pressed top or cover;

Figure 6 is a side elevation, partly broken away and partly in section, showing the tool applied as an extractor;

Figure 7 is a fragmentary, detail, perspective view of the tack-engaging edge of the front wall of the container. I

" Referring to the drawings, the numeral l0 designates generally a thumb-tack-applying and-re moving or extracting tool constructed according to an embodiment of 'my invention. The tool I0 is used as a-compo'site or combined tool to obviate the necessity for the use of separate tools in applying and removing thumb tacks, and obviously will preclude the possibility'of damaging or injuring-ones fingernails in removing thumb tacks and the like from a board or work piece with which the thumb tack T has been penetratingly engaged. e

The tool H is formed with asubstantia'llycubi cal receptacle .H open at the upper endthereof having a handle 12 fixed on one end wall thereof. The receptacle H is formed witha bottom rectangular floor or wall M, a rear end wall 15 extending perpendicularly upwardly from the rear edge of the bottom wall I4, and a front end wall l6 extending perpendicularly upwardly from the front .edge'of thebottom Wall l4 substantially parallel to-the rearend wall I5. A pair of longitudinally-extending side walls I! are fixed to or formed on the bottom wall I 4 and engage at their opposite ends with the respective side edges of the front and rear transverse Walls IE and I5, respectively. The bottom, side and end walls definea substantially cubical receptacle ll open on the upper side thereof.

The handle 12 is fixedly secured to the rea .end wall. [5 adjacent the upper transverse edge thereofin'amanner whereby the'receptacle may constitute a hammer head or mallet for driving thumbtacks T into a drawing board B, or other suitable member adapted to penetratinglyre 'ceive theth'umb' tacks; Generally; however, the tack 'I wiljl be pressed into the work piece by the finger pressure of an-operator *on the top of the receptacle 1 l.

(For removably securing the thumb tack T on the receptacle I L'a suitable magnet -l8"is fixedly secured on the forward end of the bottom wall icon the lower side thereof. The magnet I8 is formed with a concave lower side!!! for smoothly engaging the conventional convex headIHof the thumb tack T. When 'thetack T is drawn intoengagement withthev face 19 of the magnet l8, theengagement of the convex head H with the concave face 19 will providefor the ready positioning of the tack T at a selected angle to be engaged into the work piece B. When the point P of the tack is penetratingly engaged in the board B, the tool I0 may be readily disengaged from the tack by the application of an upward spaced apart at their upper ends defining a tackreceiving passage within which the shank of the tack will be received when it is desired to remove the tack from the board B. The jaws 2| and 22 Iclaim:

1. A tack tool comprising a hollow receptacle having a bottom wall, opposing upstanding side walls and an upstanding front and rear wall, a handle projecting outwardly from the rear wall for swinging said receptable, an upwardly divergent V-shaped notch formed on the upper edge of the front wall thereof for extracting a tack from a workpiece, the lower edge of the front wall forming a fulcrum about which the receptable is swung by the handle to extract a tack from a workpiece and a spring urged closure pivotally mounted at one end on the upper edge of the will be slidably engaged between the lower'side of the tack head H and the board B, with the shank disposed downwardly alongfthe cut-out as far as possible. pivotal movement of the handle I2 about the rear bottom corner of the container II as a fulcrum will lift the jaws upwardly and pull the tack T from the board B.

V -A cover plate 24 ispivotally mounted on the rear end of the container I I for closing the upper open side thereof. The closure 24 is formed with a horizontal, top, flat plate 25 overlying th upper edges of the side and end walls. A flange 26 depends from the front and side edges of the plate 25 and overlies the outside surface of those walls in the closed position of the cover 24. The flange overlying the front wall I6 partially closes the notch 20 and completely closes the upper open end thereof, in the closed position. A transverse pivot or hinge pin 21 is engaged through the rear ends of. the flange 26 and through the upper rear ends of the sidewalls H for hingedly mounting the cover for swinging from an open to a closed position. A spring 28 is coiled about the pin 21 and one end of the spring engages the upper edge of the rear wall I5, while the other end engages the lower side of the plate 25 rearwardly of the pin for biasing the cover to a closed position.

- When the extractor I I] is used as such, the cover is initially opened, as noted in Figure 6 of the drawings, while the jaws 2| and 22 are engaged under the tack to be pulled. As the cover is biased to the closed position when the tackis drawn from the board B, the cover will confine the snapping 'or suddenly-released movement of the tack to the interior of the receptacle, thus limiting the uncontrolled flying of the tack'and precluding the necessity for a search for the drawn'tack after it has been removed from 'a board'B." Y

A handle bar 29 is fixed on the closure plate 25 and extends rearwardly and normally upwardly inclined over the handle I2. The bar 29 extends upwardly and rearwardly from the hinge pin'21, whereby, upon swinging the bar 29 into overlying, abutting, or closely-overlying relation to the handle I2, the cover II will be swung to the open position. The spring 28 will normally bias the cover I I closed and the handle bar 29 to rearwardly-divergent relation to the handle I2.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims. V I
