Application December 21, B946 Serial No; 717391 3 Glaims.
invention is concerned withimprovements in a t'acker or staple driving device of the type employing U shaped staples.
Fastener or staple driving devi'cesof the general type which include avertical reciprocatin staple driving blade and a staple feeding mechanism for positioning the staples in driving positionbeneath the bladefrequently become-jammed or clogged due to the staples being too large or too small on of incorrect formtobe properly positioned for driving" in the guideway beneath the driving blade. In order'to-remove the jammed staple andclear the device for subsequent operations, it isgenerally necessary to disassemble at least aportion of the mechanism.
The object of my invention is'to provide in a fastener driving deviceimproved means for efifectingquick and easy removal'of ajammed or damaged staple without any disassembly of the staple driving mechanism.
Other objectsand advantages ofmy invention will be apparent to those skilled in the art from a descriptionlof the preferrediembodiment of my invention which is shown by'way of illustration in the accompanying-drawings; wherein:
Fig. l is a perspective view of a fastener driving device embodying thepri'nciples of my'invention;
Fig. 2 is a sideelevation of the device; to an enlargedscale; withportionsbroken away;
Fig. 3 is a; front; end elevation of the device;
Fig. 4 is. a sideelevationlof. the front portion of the device. with parts broken. away; and.
Fig. 5 is a perspective viewof a-removable front wall section of the device.
My invention is applicable to all kinds of fastener driving devices such as stapling machines, compression tackers, magazine hammers, etc., and I have illustrated only one application thereof. For convenience, I have shown my invention embodied'in a tacker used for driving U-shaped staples into wood, cardboard or other surfaces. A tacker of this type is shown and described in my copending application Serial No. 626,675, filed November 5, 1945, to which reference is made for a detailed description of those features which it is not deemed necessary to describe in detail in this application.
The tacker' comprises a generally U-shaped frame I having a forward chamber or driving head I I formed by the spaced vertical fram side plates I2 and I3. The forward ends of side plates I2 and I3 are turned inwardly at I4 and I to form part of the front face of the tacker and the forward side of a guideway for the driving 2 plunger I61 The driving: plunger I6'is vertically reciprocal in the guideway'formedin thef onward portion of the-head I=I'.
The driving plunger It is actuated bya compression spring Hwhich is seated: in a recess- I8 in the top of the plunger I6 and extends to the cap I9 at the top of theguideway. Astaple'driving plate or blade 20 is secured to: the frontof the plunger I6 by a pin 2 I'.
The driving plunger H5 is elevated-to compress the spring I] and then re1eased forthe-driving stroke by pivotaloperation ofalever or handle 22 and a: trip mechanism: (not shown) within the driving head II whichicoope'r atestherewith.
A bumper block 23 is secured immediately beneath the driving plunger Ifiand a shock-absorb inggbum-permechanism 24 is provided'in the forward portion: thereof for engagement with the lower end ofthe-driving'plunger I 6 to cushion the shock at the end of the driving stroke;
A staple supply and, delivery mechanism 25'is arranged beneath the bumper block 23' in the horizontal chamber or magazine 26- formed by side frame members I2, I3: and bottom frame member 2-]. The chamber 26' extends'rearwardly from thedriving; head- I I and'the staple delivery mechanism 254s removable atthe rear to reload the "mechanism with-a supply'of staples 28-;
The front flanges I4 and I5 are cut away at their lower portions, terminating at 29 and30 (Fig; 3). A- removable front'wall section 3| is provided which forms the lower front portion of the-guidewa'y for the staple driving blade 20. The front wall .sectionvor' memberi3l 1 (Fig. 5) is provided: with I rearwardly. extending side flanges: 32 and 33 which are adapted to embrace the lower portions of side walls I2, I3 of the head II. The flanges 32 and 33 are provided with aligned apertures 34 for receiving a removable locking pin 35 to secure the member 3! in locked position on the front of the head portion II. The locking pin 35 is retained in a recess 36 which is formed by aligned apertures in the bumper block 23 and the frame side walls I2 and I3, the locking pin being held therein so that it may be removed by a force driving it in an axial direction.
The front wall member 3| is provided with an aperture 31 which (Figs. 2 and 4) is in alignment with the forward delivery end of the staple supply chamber 26. The aperture 31 is narrower than the width of the staple being used so that the legs of the first staple in the magazine '26 engage with the rear face of the front wall section 3| adjacent the side edges of the aperture 31 to position the staple beneath the blade 20 for the 3 driving operation. The height of the aperture 31 is sufficient to provide access to the top of the staple magazine 26 in which the bightrportion of the staple moves. 7
With this arrangement when the blade 20 is elevated for the driving operation as in Fig. 4 the forward staple is projected into driving position below the same by the staple feeding mechanism 25 and thereafter the driving plunger 16 is released to drive the staple. If there is any failure of the staple resulting in a clogging or jam ming of the mechanism the aperture 3"! permits the insertion of a pointed tool, or the like, by means of which the jammed or defective staple may be withdrawn or removed and the mechanism may be freed for operating on the succeeding staples in the magazine without the removal of the staple feeding mechanism 25, the front wall section 3| or any of the other parts of the device.
While I have referred to particular details of construction in describing the device illustrating the principles of my invention, it will be understood that other details of construction may be resorted to within the spirit of my invention.
I claim:
1. In a device for driving U-shaped staples comprising a forward chamber having a generally vertical guideway therein, a generally horizontal staple supply chamber communicating with the lower portion of said vertical guideway, a reciprocal staple driving member operable in said guideway, staple feeding means to deliver successive staples from said staple supply chamber into said vertical guideway beneath said staple driving member, and means for actuating said staple driving member to drive said staples, said vertical guideway being formed at the lower end thereof by a forward wall member having an aperture therein, said aperture being located above the lower edge of the forward wall member with the top edge of the aperture above the forward path of the staple as it is fed forward from the horizontal supply chamber and with the side edges of the aperture inwardly of the path of the side edges of the staple whereby a jammed staple may be readily removed from said device without disassembly of any of the parts of said device.
2.

3. In a stapling machine, comprising a forward chamber having a generally vertical guideway therein, a laterally extending staple supply chamber communicating with the lower portion of said guideway, a reciprocable staple driving member in said vertical guideway, means for feeding staples successively from said supply chamber into driving position in said vertical guideway, and means for actuating said staple driving member to drive successive staples, the forward side of said guideway being defined by a forward wall portion having an aperture therein, said aperture being arranged in spaced relation to the bottom edge of said forward wall portion and in alignment with the forward end of said staple supply chamber, and said aperture being narrower than said supply chamber and approximately the height of the same whereby to permit removal of a jammed staple from said vertical guideway and said staple supply chamber.
