TACKEIR AND METHOD OF SECURING A FOLLOWER WITHIN A MAGAZINE Filed May 24, 1963 SSheets-Sheet 3 /4 /7 4 H I? 4/ 42 ml 42 :11 53 E INVENTORS ELL/OTT J. LASH BY MENACHEM FUTTER United States Pater dice Patented Aug, ML, 3955 til SEQURiNG A xiii. i A MAGAZlNE "out, lvlenachem Fetter, Jamaica, io ine inc, Island (City,

'ew York This invention relates to a taclrer having a number of novel structural components. The structure of the ram, the ram spring, the follower, and the magazine are novel in and of themselves and are separately claimed in this application. However the novel components also comhide to produce a superior tacker to those heretofore manufactured.

The inve tion also relates to the method of securing a follower v do a magazine which is done simply, easily, and econon icaliy.

Conventionally a tacker consists of a spring loaded ram, a driver blade secured to the ram, a trigger actuating the ram, a magazine, a spring loaded follower within the ma .zine, a fastener driving opening at the forward end of the magazine. The magazine must contain some type of latching means to permit the insertion of fasteners in laterally ali .ed relationship therewithin and to secure iese fasteners in position after their insertion. innumerable structures have been devised including the above components and have performed in a satisfactory manner.

in the instant invention, one of the novel features in volved, resides in the fact that the spring which controls the trigger ulso controls the latching means for opening and closing the magazine. Thus one spring is made to perform two functions at a great saving cost, material,

assembly time.

Furt'; re, in the instant invention, the magazine and follower con'ibination is very simply assembled. The me e is provided with a longitudinal slot therealong having a transversely enlarged portion at the rear thereof and the follower i provided with a pair of spaced outwardly extending supports which project from the top thereof. The spaced outwardly extending supports are ted to pass through the transversely enlarged portion so that the outwardly extending supports are passed -1 the transversely enlarged portion. The follower n slid along the slot, and a stop member is then placed in position behind the follower which prevents the follower from m rearv/ardly far enough to abut the transversely enlarged portion thus providing a very simple and method for assembly of the components.

The ram or" the tacker of this invention is also of novel construction and is integral. it consists of a base, a pair of spaced upstanding substantially rigid members carried by the base, a pair of substantially rigid offset angularly (preferably right angularly) disposed members laterally extending from a upstanding member, with each of the angularly disposed members also being laterally interlocked with the other upstanding member. This provides a rigid strong construction but one which can be easily formed by automatic equipment,

The ram of the tacker of this invention has a driver lade secured thereto as in conventional structures.

The invention will now be described by reference to the accompanying drawings which are made a part of this specification.

The inventions of this application will now be further described by reference to the specific forms as shown in the drawings which represent the best modes known to the inventors of taking advantage of the same. However the reader is cautioned to note that the specific forms of these inventions as set forth in the foregoing specification are for illustrative purposes and for purposes of example only. Various changes and modifications could obvious- 1y be made within the spirit and scope of these inventions and would occur to those skilled in this art.

The taclter ll of this invention is formed with a frame 12 which is provided with a hand opening 13 therewithin. A magazine to is carried by frame 12 and is provided with a fastener driving opening 15 at its forward portion thereof. Magazine 14 also has a roof portion in which is provided with a longitudinal slot 17 therewithin. Slot 17 bears a pair of spaced transversely enlarged portions 18 and 280 at the rear thereof. A follower i9 is formed with a top ill and a pair of downwardly depending side portions 21. Top 2% of follower 19 carries a forward pair 22 and a rearward pair 23 of spaced outwardly eX- tending supports which project upwardly from top 2%. Supports 22 and 23 are partially and slidably disposed within slot 17 and are capable of passing through portions 15 and 18a respectively when adjacent such portions.

Magazine 14 bears a pivotally openable cover 24 which is f rmed with a fastener supporting rail 25 therewithin. A coil spring 25 is secured at one nod 28 to a downwardly depending hool; 27 carried by follower 19 The other end 29 of coil spring 25 is secured to book 30 which is carried by cover 2 5 of magazine 1 Cover 24 may optionally bear a staple remover 31 at its rear if desired. 1

Cover 24 also is formed with a pair of spaced lateral locking portions 3Zwnich bear hooks 33 at their ends. Cover 2 and magazine 14 are each provided with alignable holes 34. A pin 35 is disposed within aligned holes 34 thereby pivotally securing cover 2% to magazine 1-4. Aiirst arc'uately compressible coil spring Stris disposed about pin 35 and bears apair of outwardly extending arms 37 and 38. Arm 37 is disposed within hoiding portion 39 carried by cover 24 while arm 38 bears against he inner face 4-6 of frame 1.

Spring 36 normally holds cover 24 in position.

In assembled condition the rear portion of follower 19 is abuttable with pin 35 and supports 22 and 23 normally cannot move further rearwardly than the points in dicated in PEG. 4.

Latch 41 is formed with a pair of spaced arms :2

Hook are'adapted to mesh with hook portions 33 upon cover 24. Arms 42 are joined to one another by bar 44.

Each of arms .42 of latch 41 is provided with a hole therewithin (not shown) and frame 12 is also providedwith an additional hole (not shown). The holes within arm 42 and frame 12 are alignab-le with one another. rigger is formed with a pair of spaced arms 4-7 which in turn carry projections 45 (FIG. 2). Each of arms 2-7 is also provided with an aligned slot 48, of larger diameter than the hole within arms 42 and frame 12. A pin 49, of approximately equal diameter to the holes within arms 42 and frame 12 is disposed within said aligned holes and within slot 48.

A second arcuately compressible coil spring 52 is disposed about pin 4. Spring 52 is formed with a pair of outwardly extending arms 53 and 54. Arm 53 is secured within recess which is provided within an overlying portion 3d of bar Arm 54 of spring 52 is disposed within arcuate recess 57 provided within trigger 46. Thus trigger 46 is pivotaliy movable about frame 12 but also is slidably movable by reason of the larger size of slot 43.

Wheel is disposed between the upper portions of arms 47 of trigger 4s and is secured in position by pin 51.

Ram 59 is preferably of integral construction and comprises a base portion 6% a first upstanding substantially rigid portion 61, a second upstanding substantially rigid portion (:2. Portion 61 is provided with a pair'of spaced recesses 5% which are adapted to accommodate projections 45 of trigger 46. V

Portion s2 carries a pair of spaced projections as thereupon and also bears a pair of substantially right angled lateral portions 64. Each of portions 64 bear a tab 65 which in turn mesh with recesses 66 provided upon member 61. Therefore ram 59 is of substantially rectangular configuration having a closed base and an open top.

Driver blade 67 is provided with a pair of spaced recesses as which are adapted to accommodate projections 63 of ram 59.

Frame 12 carries a front portion 69. Front portion 69 is formed with a pair of spaced holes which are alignable with corresponding spaced holes located within framelZ. Operating handle iil is pivotally secured to frame 12. Operating handle Til overlies wheel Sit and is provided with a cut-out portion 72 and a hole. A pin 71 passes through the hole within operating handle in and the aligned holes in frame 12 and front portion 6h. .A pin '73 passes through the aligned holes within frame 12 and front portion 69. A latch 74- is pivotally secured topin 49 and may be locked in down position by projections '75.

Front portion 69 is formed with a roof 76. A coil spring 77 is disposed within ram 59 and abuts roof '76..

An additional coil spring 78 is disposed within spring 77. A bumper '7? is disposed within front portion 69.

.driverrblade 67 leaves recess 15.

The assembly of the tacker of this invention is obvious from the construction of one skilled in the art and need not be specifically set forth. However the positioning of the follower 1% within the magazine 14 will be specifically explained.

Frame 1.2 is obtained and the reader will note that slot 17 bears enlarged transverse slot portions 18 and 12a. The reader will also note that'follower If) bears projections 22 and 23 and that projections 22 and 23 pass through portions 1% and id a. Frojections 22 and .23 are pushed through slots and Eda and follower 19 then slid for- ".vardly along slot 17. Cover 24 is then obtained. Pin

35 is then passed through one hole within cover-24 and through one of the aligned holes within frame 12. Spring is then placed about pin 35 and pin 35 then passed through the'opposite aligned holes within frame 12 and cover 24. Pin 35 is then rivetted in position and arm 37 of spring 36 locked within holding portion 3?. Spring is then hooked into ho0k'27 of follower 19 and into hook 3% and cover A As can be seen from FIG. 2 of the drawings when follower 1% now moves rearwardly it will abut spring 3-5. The construction is so made that the rearwardmost permitted movement of follower 1Q will not permit projections and 23 to be aligned with slot portions 18 and not be removed therefrom without disassembly of the V taclier.

Cover 24 of magazine 14 is pivotally removed there- 7 from by movement of latch 41 in the direction of the arrow shown in FIG. 1. Movement of latch 41 is performed against the pressure of spring 52. The movement of latch 51 causes hooks 33 and hooks 43 to become disengaged from one another and arm 37 of spring 36 causes coverZd to pivot away from magazine id. Cover 24 is then moved manually in an arcuate direction as shown by the arrow in PK 2. Spring 25 then cause-s follower 19 to assume its most permitted rearward position. Frame 12 is then overturned bottom up and a strip of staples placed within magazine 14 bottom up. Cover 24 is then pivotally moved to its normal closed position while the tacker is in overturned position and books 33 and 43 then snapped together by reason of the construction of the parts. The tacker is then made available for use by movement of member .74 in a downward direction so as to clearrecess 72 and permit operating handle to assume theposition shown in FIG. 2. Trigger 46 then contacts recesses 53 within ram 59. As operating handle '70 is pushed downwardly trigger 46 lifts ram 59 until The forward pressure on follower 19 caused by spring 26 then causes a staple to intervene opening 15 and underlie driver blade 67. As operating handle '74? is depressed still further the pivotal movement of trigger as causes projections 45 to leave recesses 58 and thus causes ram 59 under pressure of springs 77 and 78 to move downwardly with considerable force driving'the intervening staple into the work. The force of the downward movement of ram 59 is absorbed by bumper 79.

As operating handle 7%) is released spring 52 causes trigger ddto assume its normal position. At the same time the rearward pressure exerted upon trigger 46 causes it to slide rearwardly through slot 48 so as to permit trig ger tdto slide along ram 59 andagain contact recesses 58 for another stroke. V

The foregoing description indicates the manner in which the objects of this invention are achieved.
