Patented Apr. 22, 1952 @FICE FEEDING AND CUTTING MEANS FOR FORMING FASTENERS Andr Adler and Robert Adler, Paris, France Application September 22, 1947, Serial No. 775,550 In France November 7, 1946 Our present invention relates to a nailing device which is adapted to sever one by one a succession of uniform sections of a Wire or a metal strip and to drive them in as they are severed.
The apparatus is particularly applicable for thev 3 Claims. (Cl. 164-48) shears and secondly to feed a wire or strip feeding means as far as a stop arranged at a requisite spacing beyond the shears.
The accompanying drawings illustrate by way of example only, one embodimentl of our improved nailing device.
Fig. 1 is a longitudinal cross section intermediate plane of the device;
Fig. 2 is a transverse cross section on line II--II of Fig. 1;
Fig. 3 is a horizontal cross section on line III--III of Fig. l;
Fig. 4 is a separate perspective showing the fastener driver.
Figures 5 and 6 are perspective views showing the fixing of the cover for the strip magazine and illustrate the operation of the device.
Figure 7 is a perspective view of the device i1- lustrating the operation thereof.
As shown in the drawings, the operative mechanism of the nailing device is enclosed in a at along an casing formed of a juxtaposed pair of parts I and 2. Said casing is formed with wide perforations in its central portion` At its bottom it ares out to form a flat base.
One of the casing portions I carries at its rear a circular supply magazine 3 adapted to receive a provision of wire or metal strip stock wound into a fiat coil. Said magazine is provided with a cover (not shown) formed With a central aperture into which projects a boss 4 projecting from the bottom of the magazine. Said boss has pivoted thereon strip member 5 adapted to latch the cover in position.
The foremost end of the casing I-2 contains the movable member or blade 6 of the shear means which blade is adapted to cooperate through the rear cutting edge in its base with the forward upper edge of a xed anvil 1. The blade 6 is slidably guided by two spacers 8 9 of the casing. The blade is maintained against said spacers by means of a movable stop member I0 2 which is formed with a spring at its top andwhich in turn is held in position by a pair or pins II and I2. The pin l2 is adapted to cooperate with a pair of notches ia, I2b formed on the push member I3. The back of the movable stop member has a push-member i3 which projects outwards of the casing. Adjacent to its base the stop member is formed with a shoulder or step lli directed towards the shear means.
The shear means is actuated by means of a hand lever I5 accommodated in the central recess of the casing and pivoted thereto at I5a. Said lever is formed with an upper arm I6 and a lower arm Il. The arm IB has attached thereto a biassing spring I8 *accommodated in the upper part of the casing which forms a grasping handle and is anchored to a iixed projection I8-a. The arm Il has a pinV I9 extending therethrough which pin is connected to another pin 20 through links 2l', arranged at each lside of the member 6. The pin 20 extends through the member 6 through an angular slot 22 having an upwardly inclined portion followed by a longitudinally extending portion.
The ends of the pin Z extend on both sides of the links 2I and are guided in the longitudinal slides 20a of the casing.
The arm I l terminates in a nose adapted to engage the upper forward end of a dog 23a piv'oted at 23h to block 23 intermediate the lateral extent of said block. The block 23 is longitudinally guided by means of two rods 24 (Figures 2, 3 and 6) at the base of the casing. It is urged towards the arm Il by springs 25 surrounding the rods 24. A longitudinally extending groove 26a is formed in its bottom face and this groove receives one arm 26 of an L-shaped slide-block 2.5-21, the upstanding arm 2l of whi-ch projects behind the block 23. The slideblock 26, 27 is provided with a longitudinal rod 28 guided in a bore formed in a block 29 pivoted to the casing at 35. A spring 3| surrounds the rod 28 between the block 29 and the rslide-block 26-21 to urge the latter forwardly.
The top of the block 23 (Figures 1 and 2) is recessed in the portion thereof intermediate its 26-2'1 and the block 29 (Figures 1 and 2) are formed with longitudinal splits 32 and 33 respectively opening on the same side of said parts. The side wall of the casing and that of the magazine are each formed with 3 zspli; 33a, and 33h in alignment with the splits Each of slide blocks 26-27 and the block 29 (Figure 1) are formed with a hole extending from their front face below the splits 32 and 33 and extending into said split at an angle. 34-35 enclosed in said hole acts on a ball 36-31 to urge the latter towards the upper Wall of the slit.
Under the block 23 two transverse splits 38-38 (Fig. 2) are formed in a common plane. They are adapted to receive bent-back lugs 39e- 39a formed on a fastener driver 39 (Fig. 4) adapted to slide under the bottom face of the casing. The opposite end of said fastener driver has a notch 39h formed therein the width of which corresponds with that of the strip or wire fed to the device. The fastener driver 39 is held in engagement with the block 23 by means of a bottom plate 49 slidably mounted under the bottom of the casing i-ia. The bottom plate 49 is provided with rubber mountings il as shown in Figure 1.
To use the device, the end of the strip or wire contained in the magazine 3 is successively threaded into the slit formed in the block 29 then the slit in the slide-block 25-21 and over the anvil l, until it engages the stop member i see Figure 2. The balls 33--37 do not oppose the movement of the wire or strip in this direction.
If it is desired for instance, to secure a window pane in a wooden window frame, the base of the casing is laid against the pane and the forward 0i said base is applied against the transverse section of the window frame element A spring involved in the nailing operation. Grasping in one hand the upper part of the casing and at the same time the lever i5, the latter is rocked upwardly. The nose of the arm l1 starts pushing back the block 23 and the slide-block 25-27 which in this direction do not exert any pull upon the wire or strip. At the same time, said arm Il pulls the links 2| which in turn force the pin 26 along the angular slot 22 of the shear blade 6. This results in a downward movement of said blade which is effective to sever the strip or wire flush with the anvil 1. The severed section of the strip or wire drops into the terminal notch 39D of the driver 33. At the end of the shearing operation, the pini lies in the longitudinal arm of the slot 22 in the blade 6. The latter is therefore arrested from any further downward movement.
Finally, the arm I7 of the lever i3 releases the front edge of the dog 23a. The block 23 is then vigorously projected forward by the sudden re'- lease of the springs 25, which together with the fastener driver 39, drives the severed Wire or strip section to force it into the frame element worked on.
When the lever I5 is thereafter acted on by biassing spring I8, the arm I'! returns to itsposition in front of the dog 23a.. The dog 23a. pivots to allow arm lI to pass and is ultimately restored opposite to said arm l1 by the action of the spring 23e. At the same time, the slide-block 23--27 follows the block 23, because of the release of the block 3|, andrcarries with it the strip or wire until it abuts against the stop member lll.
When stop member I is in the position shown in Fig. 1 the severed section of strip or Wire is 'Til 4 shorter, by the full amount of the depth of the shoulder I4, and when said stop member l0 is in its raised position, the end of the strip or wire extends to the inner Wall of shoulder i4 so that it becomes longer by the amount of the depth of shoulder I4.
The apparatus instead of being controlled manually may be adapted for mechanical control as for instance with an electric motor or by pneumatic means.
