8 Claims.

This invention relates to, improvements in stapling machines wherein are employed a staple clinching anvil, a member movable on the ma! chine frame toward and from the anvil, and having a work receiving opening and staple guiding means extending from above the opening to and through the side walls thereof, a staple driver operating within said member, and means operable to move said member and the staple driver relatively to each other and to the anvil to effect the staple driving and clinching operation.

An object of the present invention is to provide a stapling machine of the aforesaid general character with a novel and advantageous means whereby relatively wide, flat work of thin material, such, for example, as a flattened tube formed of thin material, may be crumpled upon itself and banded or surrounded by the staple to close a part of the tube.

Another object of the invention is to improve the construction and operation of the machine whereby, after the staple clinching operation, the staple guiding member will be raised from the anvil and moved upwardly with relation to the staple driver before the driver is moved upwardly with relation to the member, for the purpose of loosening the work within or ejecting it from the work embracing part of the member, to permit the easy removal of the stapled work from, the machine.

The invention resides in the elements and the combinations of them hereinafter described and claimed.

Figure 12 is a side view of a portion of work having a staple applied thereto by the machine, enlarged.

Figure 18 is a section line |2| 3 of Fig. 12.

Referring to the drawings, 2 designates the frame of the machine comprising a base 3, secured upon a suitable support 4, forward and rearward standards l0 and II, respectively, rising from the base 3, and an arch-like upper structure It connecting the standards It and II.

The forward standard ||l supports a staple clinching anvil l5 formed integral witha stem l6 which is set in a bore in the standard l0 and secured therein by a set screw ll, Fig. 5.

Pivoted, at I 8, on the rearward standard II is the rearward end portion of a member I! whose forward position is movable toward and from the anvil I5.

One side of the member I! is grooved and forms a magazine 20, for a row of staples 2|. The staples 2| slidably embrace a guiding rib 22 which extends longitudinally in th magazine 2|land is secured to the bottom thereof. The staples 2| are guided by the rib 22 and they are moved forwardly thereon and into a staple guiding channel 23 which extends up and down through the work, on

' transversely of the rib 22, and which is formed by the forward end wall ofthe rib and by and between two blocks 24 and 25 which are suitably secured within an opening in the member I! back of a front plate 26 which is secured to the member |9 by screws 21.

The staples 2| are fed forwardly on the guidthe member l3 in the usual manner.

' into registry with the ball.

secured thereto. the upper ends of two links 48, 45 on the respecing rib '22 toward and into contact with the front wall 23 of the channel 23 by a' suitable -follower 23 which embraces and is slidably fitted to the rib 22, and which is urged forwardly by a spring 30 which is connected thereto and to The space between the front end of the rib 22 and the wall 23 is equalto or slightly in excess of the thickness of a staple.

The lower portion of a staple driving plate 3| is fitted to slide in the channel 23 toward and from the anvil l5, and the lower end of the driving plate 3| is made concave in form, as shown,

for a purpose hereinafter described. The upper .end of the staple driver 3| is secured to a block 32 which is fitted to slide within an upwardly extending limb of the forward end portion of the member l3.

The block 32 is secured to the lower end of a stem 33 which extends upwardly from the block 32"through a sleeve 34 which is fitted to slide spring .36 encircles the stem 33 within the bore 35, between the block 32 andthe upper end of the bore, and urges the block and staple driver 3| downwardly with relation to the sleeve 34. The upper end portion of the stem 33 extends above the top of the sleeve 34 and carries a washer 31 and a nut 38, which engage the top of the sleeve 34 and limits the extent of the downward movement of the stem 33 and staple driver 3| with relation to the sleeve 34. The extent of the upward movement of the stem 33 and staple driver 3| with relation to the sleeve 34 is limited by'a shouldered portion 33 of the block 32 which is adapted to engage the bottom of the sleeve 34.

The staple driver 3|, block 32, stem 33 and sleeve 34 are adapted to be moved up and down as a unit within the member I3, and they are also adapted to be connected to and disconnected from the member by releasable means which causes them to be moved by and with the member, under certain conditions, and which permits the member to be moved independently of them, under certain other conditions, presently described. This releasable means comprises a I spring pressed ball 40 which is adapted to enter either of the two spaced sockets 4|, 4| in the sleeve 34, when either of the sockets is moved The ball 43 moves within the inner end portion of an opening or bore 42 in the member l3, and it is urged toward the sleeve by a spring 43 within the bore and acting between the ball 43 and a plug screwed into the outer threaded end portion of the bore.

The upper end portion of the sleeve 34 has a block or collar 45 surrounding the same and This collar 45 is connected to tive sides of the member Ill. The links 45, 43 extend downwardly from the collar 45, and the lower ends of the links are connected by pivot screws 4], 41 to the forward, bifurcated end of a lever 48 which is fulcrumed at 43, on the member l3, and which is pivotally connected to the upper end of an operating bar 50 which extends downwardly from the lever 48 and through suitable openings in the base 3 and table 4. The

the pins 5|, 5| being provided to move down and up within the slots 52, 52 and to engage the upper end walls thereof, Fig. 5.

A spring 53 is interposed between the member l3 and lever 48 which tends to raise the forward end portion of the lever with relation to the member, and which permits the lever to be moved downwardly with relation to the member from the position shown in Fig. 1 to the position shown in Fig. 2.

Upward movement of the member I3 with relation to the machine frame is stopped by the engagement of a projection 54 on the member with a lug 55 on the frame 2, and downward move ment of the member I3 is stopped by the engagement of a projection 58 on the member with an adjustable stop screw 51 carried by a boss on the machine frame 2.

Upward movement of the lever 43 with relation to the member I3 is stopped by the engagement of the stop pins 5|, 5| with the upper end walls of the slots 52, 52 and downward movement of the lever 48 with relation to the member I3 is stopped by the engagement of the 'collar 45 with the top of the upwardly extending limb of the member l3.

The machine is operated by lowering and raising the operating bar 53, and this may be accomplished by any suitable means. When the bar 53 is operated by a pedal connected thereto, the bar is held normally in the raised position, with the projection 54 in engagement with the lug 55, as shown in Fig. 1, by a spring 58, one end of vwhich is attached to the operating bar 50 and the other end of which is attached to the table 4, whereby the bar 53 may be lowered by the operation of the pedal and raised by the spring.

The staple driver 3| is operated, as hereinafter described, to drive the staples down through the staple guiding means or channel 23 which extends downwardly from the staple guiding rib 22 and between the blocks 24 and 25. These blocks and the channel 23 formed between them extend downwardly from the forward end of the member l3, and the blocks 24 and 25 have a work-receiving opening 53 therein which extends completely through the blocks transversely of the anvil l5, as shown in the drawings.

The opening 53 crosses and extends through the staple guiding channel 23, and the width of the opening 53 is equal to or slightly less than the space between the legs of a staple, and the sides of the channel 23 which guide the staple legs extend through the side walls of the opening 53 to the bottom thereof, as shown in Fig. 5.

The forward portion of the block 25 is provided with two laterally spaced arms 30, 63 which extend downwardly from the block forwardly of the anvil |5 on the respective sides of the for ward portion of the work receiving opening 53; and the rearward portion of the block 24 is provided with two laterally spaced arms 5 I, 6| which are located directly back of the arms 80, 33 and extend downwardly from the block 24 rearwardly of the anvil l5 on the respective sides of the rearward portion of the work receiving opening 53. v

These arms 60, 60 and 5|, 6| extend to and below the top of the anvil I5, when the member I3 is in the raised or normal position, as shown in Fig. 1, and the arms are curved, as shown, to permit them to move in close relation to the anvil when the member I3 is lowered and raised on its pivot Hi.

The opposing inner walls of the two pairs of arms 53, 50 and 6|, 5|. are tapered or flared downwardly and outwardly from the'lower ends of the sides of the work receiving opening 58 and constitute continuatlons of the forward and rearward portions of the side walls of the opening to receive work placed upon the anvil between the arms of the two pairs thereof and direct such work into the opening 59 when the parts 92, 82 are carried by a cylinder 98' which extends through and is fitted to turn in an opening in a part of the forward frame standard l9. The left hand end or work supporting portions of these pins extend from the cylinder 98, and they embrace the two pairs of arms 69, 99 and 9|, 8| and cross the space between the arms of each pair, one pin 62 being located forwardly of the arms and the other pin being located rearwardly of the arms. The top surfaces of the work supporting portions of the pins 52, 92 are above the top of the staple clinching anvil IS in the normal position of the pins, as shown in Figs. 1 and 5, and the pins are adapted to be depressed to move the work supporting and opposing portions thereof down to a position below the top of the anvil I5, as shown in Figs. 2 and 10. When the pins 62, 92 are thus depressed, their supporting cylinder 83 is turned in its bearing in the frame. The upward movement of the right hand end portions of the pins 52, 92 is stopped by the engagement of the top wall 54 of a slot 65 in the cylinder 63 with the upper end of a stop screw 99 which is screwed into a part of the machine frame and extends into the slot 55. The pins 52, 52 are held yieldably in the normal position shown in Fig. 5 by the pull of a spring 91 having its lower end attached to the table 4 and its upper end attached to a block 98. The block has a vertical rib 59, T-shaped in cross section, slidably fitted to a similarly shaped groove in a part of the machine frame, and it has two projections 19, I9 which extend outwardly over the free right hand end portions of the pins 62. 52 and engage and urge the same downwardly.

Extending upwardly from the space between the right hand portions of the pins 62, 52 is a plunger H fitted to slide vertically in a bore in a part of the machine frame. This plunger II has a transverse pin 12 extending through the same and outwardly through vertical slots in the machine frame to positions above the pins 52, 92. This transverse pin 12 rests upon the pins 52, 62, and, when the plunger H is depressed, the pin 12 will depress the pins 92, 82. The upper end of the plunger II is provided with an adjustable impact screw 13 which is arranged to be engaged by a lug 14 on the forward end of the lever 48 to depress the plunger and therewith the pins 52, 62 when the lever 48 is moved downwardly, as will be hereinafter described.

The forward portion of the machine is provided with an appropriately shaped funnel 15 for receiving the work to be acted on by the machine and directing the work into the opening 59 and into the spaces between arms of the two pairs thereof 59, 59 and 5|, 5| above the anvil I5 and above the work supporting pins 92, 52. This funnel 15 is formed on and supported by a bracket 16 which is secured to the forward standard l9 of the machine frame.

Secured to the member I9, and located rearwardly of the work supporting pins 92, 82, is a suitable stop plate or bracket 11 for limiting the ehxtuelnt of the insertion of the work into the mac e.

.The anvil II is provided with two adjacent grooves 19, I9 which extend side by side, as shown in Fig. 6, for receiving and guidingthe legs of a staple during the driving and clinching of the staple. These grooves have entrance openings I8, 19 in registry with the legs of a staple, as the staple descend through the channel 23. The

grooves 18, I8 are so relatively disposed that they will deflect the staple legs into lateral lapping relation during the staple driving and clinching operation, such lateral lapping relationship being clearly illustrated in the stapled work as shown in Figs. 12 and 13.

In Figs. 1, 2, 5, 9 and 19, I have shown by dotand-dash lines, indicated at 89, work in the form of a flattened tube of thin material, as acted upon by the machine.

The operation of the machine is as follows:

when the machine is in the raised or normal position, as shown in Figs. 1 and 5, the upward movement of the member I! under the urge of the spring 58 is stopped by the engagement of the projection 54 with the frame lug 55, the upward movement of the lever 48 with relation to the member I9 is stopped by the engagement of the pins 5|, 5| (Fig. 5) with the upper ends of the slots 52, 52, and the ball 49 is resting in the upper socket 4| in the sleeve 84, releasably holding the sleeve and the staple driver 3| in the raised position with relation to the member 9.

In this normal position of the parts, the work 89 to be acted upon by the machine is inserted into the machine through the funnel 15, as shown in Figs. 1 and 5. The operating bar 59 of the machine is then moved downwardly. During the initial downward movement of the bar 59, the bar moves the lever 48 and member l9 as a unit on the pivot l8 until the further downward movement of the member is stopped by the engagement of the projection 55 with the stop screw 51, with the bottom of the blocks 24 and 25 and the bottom of the staple guiding channel 23 and the bottom of the work receiving opening 59 in close relation to the top of the staple clinching anvil l5, as shown in Figs. 2, 3, 9 and 10.

During the downward movement of the member I9, the work 89 is crumpled between the arms of the two pairs thereof 59, 59 and 5|, GI and between the top of the work supporting and'opposing pins 62, 52 and the top wall of the work receiving opening 59, and, at the same time, the work 89 is directed by the arms 69, 69 and 6|, 5| into the opening 59 and between the guides for the staple legs in the side walls of the opening 59, as shown in Fig. 9, the pins 82, 92 opposing the downward movement of the bottom of the work 89, during the crumpling of the work between the top wall of the opening 59 and the pins.

During the continued downward movement of the operating bar 59, after the engagement of the projection 55 with the stop screw 51, and the crumpling of the work 89, as shown in Fig. 9, the bar 59 moves the lever 48 downwardly on its fulcrum 49 with relation to the member I9. During this downward movement of the lever 48, it causes the links 45, 45 to move the sleeve 34 and staple driver 3| downwardly. and, during the initial downward movement of the sleeve 34, the ball 49 is forced back against the action of the spring 43 and out of the lower socket 4| in the sleeve, releasing the sleeve from the member l9 and permitting the sleeve and staple driver 3| to be moved downwardly within the member.

downward movement of the staple is stopped by the staple crown engaging the work upon the anvil, after the staple clinching operation, as shown in Fig. 10, oruntil the collar 45 on the sleeve 34 engages the member l8, after the clinch-'- ing operation. As the sleeve 34 and driver 3| complete the downward movement thereof, as Just described, the ball enters the upper socket 4| in the sleeve 34, as shown inFig. 10.

During the staple driving and clinching opera- I tion, just described, the pins 52, 62 support and oppose the crumpled work 30 in the upper portion of the opening 59, as shown in Fig. 9, while the staple driver 3| moves the staple 2| downwardly and the staple legs straddle the work and extend below the same, and the staple crown contacts the work 80. At or about this stage of the operation, the lug 14 on the lever 43 engages the screw 13 and moves it and the plunger l| downwardly, causing the plunger pin I2 to depress the work supporting and opposing pins 62, 52, and thereby lower the work 80 with-the downwardly moving staple and staple driver 3| and deposit the work 30 upon the-anvil I5, while the driver is effecting the clinching of the'staple legs beneath the work, and the encirclement or bandingof the work by. the staple. The final clinching of the staple legs compresses the encircled work further and efiectively closes the tubular work acted upon; "and the concave lower end of the staple driver 3| permits the crown portion of the staple to be curved upwardly to conform to the encircled work.

During the downward movement of the sleeve 34 in driving the staple, as above described, the bottom of the sleeve moves down into engagement with the shoulder 39 of the block 32 when the resistance of the staple to the action of the staple driver 3| is suflicient to overcome the pressure of the spring 36, and, thereafter, the staple is driven and clinched by the positive action of the sleeve 34 upon the driver.

Now, after the staple has been driven and clinched, the operating bar 50 is raised by the spring 58 or other suitable means to return the parts of the machine to the raised or normal position, as shown in Figs. 1 and 5; and, during the initial upward movement of the bar 50, the bar raises the lever and member i9 as a unit.

thereby moving the member and sleeve 34 therein as a unit with relation to the staple driver 3| until the top of the washer 31 on the top of the sleeve 34 engages the nut 38 on the stem 33. This upward movement of the member l9 and sleeve 34 with relation to the staple driver 3| causes the work receiving opening 59 of the member Hi to move upwardly from the anvil l5 and also upwardly with relation to the staple driver 3| until the parts reach the position shown in Fig. 11. This upward movement of the opening 59 with relation to the driver 3| causes the latter to loosen the stapled work within or eject it from the opening 59 for the easy removal of the finished work from the machine.

After the stapled work has been thus ejected from the opening 5!, the movement ofthe lever 43 and member l9 as a unit is continued until 2,285,977 p the upwardmovement or the member is stopped by the engagement of the projection 54 with the frame lug 55, as shown in Fig. 1. This done the bar 50 moves the lever 48 upwardly with relation to the member I! to the position shown in Fig. 1;

and, at the beginning of such movement, the links 45, 46 raise the sleeve 34 within the member I! and force the ball 40 out of the upper socket 4| of the sleeve. As the upward movement of the lever 43 continues, the links 46, 45 raise the sleeve- 34 within the member I9 until the stop pins 5|, 5| engage the upper ends of the slots 52, 52 in the member l9 and the ball 40 enters the lower socket 4| in the sleeve, leaving the parts of the machine in the raised or normal position, shown in Figs. 1 and 5, for a succeeding staple driving and clinching operation. I

As the bar it raises the lever 48 to the normal position, the lug 14' is moved upwardly from the impact screw 13 and permits the spring 61 to return the work supporting and opposing pins 52, 62 and plunger to the normal position shown in Fig. 5.
