Fig. 7 is a cross-sectional view taken on line I-T of Fig. 1; and
Fig. 8 is a partial side elevational view of the device embodying the invention with parts broken away.
Referring now in detail to the drawing, I designates a tacker embodying the invention. The same comprises generally of a body |I, a depressable handle I2 pivoted thereto about pivot pin I3, a bracket I4 attached to the underside of the handle, a link I5 pivoted to the bracket as on pivot pin I3, a trigger I1 pivoted at its rear end to the lower end of the link as on pivot pin I8, and a plunger I9 adapted to be raised and abruptly released by the trigger when the handle is depressed, as will appear hereinafter.
The body comprises a pair of similar symmetrically disposed body portions 29. The body portions comprise parallel side walls 2| having lower end edges 2|a.. Extending inwardly from the side walls 2| are inwardly curved flanges 22 forming a hand hole 23. The flanges 22 have mutually contacting edges 22a as the meeting plane between said members 20. The side walls 2| have top inwardly curved portions 24 having meeting edges 24a in the plane of the edges 22a. The flanges 24 run along the top of the body members and are curved downwardly at their rear ends as at 25, and curved upwardly at their front end as at 2S. The rear ends of the body portions are cut away as at 21 for the purpose hereinafter appearing. The side walls 2|' have top edges 2S extending forwardly from the upper ends of the flanges 26. At the forward end of edges 28 are downwardly and forwardly curvedV edges 29 from which extend downwardly, straight edges 3Q.
Extending from the lower ends of edges 30 are horizontal shoulders 3|. At the forward ends of the side walls 2| are outwardly pressed U- shaped walls 32 having forward edges 33. The upper ends of the edges 33 extend to the rear ends of the edges 3|. Extending forwardly from the lower ends of edges 33 are horizontal edges 34. Extending downwardly from the forward ends of the horizontal edges 34 are front edges 35 which extend down to the underedges 2 Ia.
The side walls 2| (Fig. 8) are formed with horizontal slots 36 adjacent the front edges 35 and disposed below the outwardly pressed portions 32. Said side walls 2| are also formed with horizontal slots 38 (Fig. 4) disposed adjacent the edges 30 and above the outwardly pressed portions 32.
At the upper front corners of the body portions 20 are suitable openings to carry the transverse pivot pin or rivet I3. Fitted over 'the front of the body 20 is a front cover member 45. Said front cover member comprises a front Vwall'4ii` and parallel side walls 41. The side walls 41 are formed with suitable bearing openings through which the pivot pin I3 passes. Said side walls 41 and the side walls 2| of the body members 22 are formed with suitable registering openings to receive therethrough a bolt or screw 48. When the bolt 48 is removed the front cover member 45 may be swung forwardly and upwardly. The
`58 received in the slots 33.
4 front wall 45 has a forwardly recessed or pressed vertical portion 59 for the purpose hereinafter appearing.
Mounted on and between the side walls 2| is a bottom stop member 5| having outwardly extending lugs 52 received within the slots 3E. At its forward end, bottom stop 5| has a slot or groove 53 for the purpose hereinafter appearing. Riveted to the top of the bottom stop 5| by means of rivet 54 is a rubber-like shock absorbed 55.
Mounted on and between the side walls 2| of the body members 26 is a top stop 51 having lugs Slidably mounted for reciprocation between the body members 2G and located between the shock absorbing disc 55 and the top stop 51 is the plunger It. Said plunger I9 comprises a bottom wall 6B (Fig. 4), a front wall 6I extending upwardly therefrom, a rear wall 62 extending upwardly therefrom and parallel to the front wall, and side walls E3 extending upwardly from the bottom wall and parallel to each other.
Attached to the front wall 2| by means of rivet 64 is a driver blade 65 which moves through the groove 53 in the bottom stop 5|. The head of the rivet |54 moves through the outwardly above the recessed portion 52.
recessed portion 5&3 of the front wall 4e of cover or nose piece 45. At the upper end of the front wall il is a forwardly pressed portion S5 (Fig. 5) to contact the inner surface of the front wall The plunger is thus guided up and down as it is moved in the manner hereinafter appearing.
Disposed within the plunger and between the bottom wall 60 and the top stop 51 is a coil compression spring 61 which normally presses the plunger down against the shock absorber 65. Pressed outwardly from the side walls 63 of the plunger are raised lugs 68. The lugs 68 have krearwardly and upwardly inclined underedges 62, and rear vertical edges 1|).
It will now be understood that when the plunger I9 is raised the spring El will be compressed, and when the plunger is released the compressed spring will cause the plunger to descend forcefully to drive a staple, as will appear hereinafter.
Disposed within the bottom of the body and between the side walls 2| is a staple magazine 1|. The staple magazine 1| may be similar to the staple magazine shown in my copending application Serial No. 42,760, filed on August 6, 1948, for Tacker. Said staple magazine includes means to mount a staple strip, and means to push it forwardly to a throat 12 located at the forward end of the staple magazine and below the grooves 53, so that the driver blade may press the forwardmost staple in the staple strip down through said throat 12.
