Definitions
- T his invention relates to improvements in staple setting machines wherein are employed a staple setting anvil, a member movable toward and from the anvil and provided with staple guiding means and a staple driver adapted to cooperate with the staple guiding means and the anvil to set a staple in work placed upon the anvil.
- An object of the invention is to provide a novel and advantageous means for con trolling and actuating the staple driver under a pressure which will yield during the staple setting operation to compensate for different thicknesses of work placed upon the anvil; and which may be adjusted to provide different degrees of light yielding pressure for line or thin or delicate work and different degrees of heavy yielding pressure for thick or coarse work to compensate for slight differences in thicknesses in work being stapled by staples having prongs of uniform length, and to provide the desired different yielding aressures for different staples having prongs of varying lengths for work of greater differences in thickness.
- Another object of the invention is to provide a novel arrangement of parts which will prevent more than one staple at a time from being presented from the staple magazine to the staple driver between it and the anvil; and a further object of the invention is to provide a novel and advantageous means for adjustably supporting the staple clenching anvil.

- the frame of the machine comprises a standard 2 provided on its upper portion with a forwardly extending arm 3 and on its lower portion with base projections 6 adapted to be secured to a suitable table 7 for supporting the machine.
- a memher 9 Pivoted at 8, to the standard 2 is a memher 9 which extends forwardly from its pivot laterally adjacent to but spaced from the frame arm 3.
- the outer side of the member 9 is grooved forming a magazine 10 for the staples, and the magazine 10 is provided with a longitudinally-extending guiding rib 12 embraced by the row of staples 13 which is adapted to be fed forwardly thereon toward a wall 1 1 which is opposite to and spaced from the forward end of the rib 12 a distance equal to the thickness of a staple.
- the row of staples 13 is fed toward the wall 14 by a suitable follower 15 which is slidably fitted to the magazine 10 and attached to one end of a spring 16 which extends around a pulley 17 and through an opening in the member 9 to a lug 18 on the opposite side of the memher 9 to which the other end of the spring 16 is attached, the spring 16 acting to move the follower 15 and row of staples 13 toward the wall 14.
- the space between the wall 14 and the forward end of the staple guiding rib 12 forms part of a channel 19 which extends up and down transversely to the rib 12 and through upwardly and downwardly extending projections 20 and 21, respectively, on the forward end of the member 9.
- the projection 21 is located above a staple setting anvil 22 which is carried by a bracket 23 secured to the forward end of the frame arm 3; and the member 9 is adapted to be moved on its pivot 8 to move the bottom of the projection 21 toward and from the anvil 22 to clamp the work to be stapled between the anvil 22 and the projection 21 during the stapling operation and to raise the projection 21 from the anvil 22 to permit the removal of the stapled work and the insertion of new work to be stapled.
- the pivoted member 9 When the pivoted member 9 is raised, its upward move ment is limited by a projection 24 thereon engaging an adjustable screw 25 which is carried by a lug 26 on the standard 2. By adjusting the screw 25 the extent of the upward movement of the member 9 may be nicely regulated.
- a staple driving plate 27 is fitted to slide in the channel 19 toward and from the anvil 22.
- the staple driver 27 is secured to and extends downwardly from a block 28 which is fitted to slide within the projection 20, and the sides of the block 28 are pivotally connected to the bifurcated end of the forward arm 29 of a lever 30 which embraces the upwardly extending projection 20 of the pivoted member 9.
- the lever 30 is fulcrumed, at 31, within the bifurcated upper end of a link 32 whose lower end is pivoted, at 33, to the standard 2.
- the end of rearward arm 34 of the lever 30 is bifurcated and embraces and is pivoted, at 50, to the forward portion of a lever 35 which is fulcrumed at 36 on the upper end of an arm 37 which is also embraced by the lever arm 34.
- the lower portion of the arm 37 surrounds and is fitted to an eccentric 38 forming part of a driving member 39 which is mounted to turn freely on a shaft 40 projecting fixedly from one side of the standard 2.
- One end of the shaft 40 is inserted into a split boss 41 on the standard and firmly clamped therein by a screw 42 which is arranged to draw the sides of the split boss 42 together.
- the lever 35 has an arm 43 which extends rearwardly from its fulcrum point 36 and which has a longitudinal slot 44 formed therein.
- the bottom wall of the slot 44 has spaced notches 45 for the reception of a pin 46 which extends transversely through the slot 44.
- the outer ends of the pin 46 enter the sides of a split adjusting member 47 which embraces the bottom por tion of the lever arm 43,
- the adjusting member 47 is connected to the upper end of a spring 48 whose lower end is connected to a projection 49 on the lower portion of the arm.37.
- the spring 48 tends to draw the lever arm 35 and its fulcrum 36 toward the eccentric 38 and thereby tends to raise the lever arm 34 which is pivoted to the lever 35 forwardly of its fulcrum 36, for a purpose hereinafter explained.
- a pulley 52 mounted to turn loosely on the shaft 40 between the driving member 39 and a collar 51, fixed on the outer end of the shaft, is a pulley 52 which is adapted to be constantly driven in the direction of the arrow in Fig. 1 from any suitable source of power.
- the inner end of the pulley hub 53 has circular cavity 54 formed therein into which one end of the driving member 39 extends.
- the pulley hub 53 is adapted to rotate around the end of the driving member 39, and the hub 53 has a series of spaced outwardly-extending notches 55 which interrupt the circular Wall of the cavity 54.
- the notches 55 are adapted to be entered by the free end of a dog 56 which is pivoted, at 57, to the driving member 39 and which is fitted to a slot 60 in the member 39 to move inwardly and outwardly on its pivot 57.
- a spring 61 which presses against the member 39 and dog 56 and tends to force the free end of the dog outwardly.
- the dog 56 is held in its innermost position, as shown in the drawings, against the spring 61 by a cam 62 formed on a controlling part 63 which is pivoted, at 64, to the standard 2. Vi" hen the part 63 is rocked on its pivot 64 in the direction of the arrow in Fig.
- the driving member 39 has an outwardly extending ring or flange 6 formed thereon and cut away to form a shoulder 66to be engaged by a projection 67 on the controlling part 63 to stop the rotation of the driving member 39 when the controlling part 63 is returned to its normal position.
- the controlling part 63 has an arm 68 formed thereon which is adapted to engage a lug 69 projecting from the standard 2 to stop the further movement of the part 63 after it has been moved in the direction of the arrow sufiiciently to cause the cam 62 and projection 67 to clear the dog 56 and tooth 66, respectively, and thereby permit the driving member 39 to be rotated by and with the pulley 52.
- the dog 71 and the adjacent wall of the opening 70 are made square in cross section to prevent the dog from turning; and the dog is provided wlth an inwardly projecting pin 72 which is encircled by a sprin 73 which presses the dog 71 against the frame boss 41.
- the outer end of the dog 71 is beveled as shown and enters a similarly shaped notch 74 in the frame boss all after each revolution of the driving member 39 and thereby prevents backward turning thereof.
- the driving membe 39 is turned forwardly by the pulley 52, the dog 71 is forced by its beveled end out of the notch 74 against the action of the spring 73.
- the pivoted member 9 is adapted to be lowered toward the anvil 22, and the controlling part 63 is adapted to be moved in the direction of the arrow to start the actuation of the driving member 39 by operating a link ?5 which is pivoted, at one end at 76, to the controlling part 63 and which extends forwardly therefrom.
- the forward end of the link 75 is pivoted, at 77, to the lower portion of a link 78 whose upper end is pivoted, at 80, to the member 9.
- the link 78 extends downwardly from its pivoted connection with the link 7 5 and into a guiding slot in a lug 81 on the standard 2.
- the link 75 is held normally elevated in the position shown in the drawings by a spring 82 the lower end of which is connected thereto and the upper end of which is connected to a lug on the standard 2.
- the spring 82 holds the pivoted member 9 elevated and holds the controlling part 63 in position to prevent the rotation of the driving member 39 by the pulley 52.
- the link 7 5 is adapted to be depressed by a suitable foot pedal, not shown, connected to a bar 83 whose upper end is pivoted to the link 7 5.
- a pin 84C Slidably fitted within an opening in the lever arm 29 is a pin 84C having a head 85 on the lower end thereof; and encircling the pin Bet and housed within a cavity in the lever arm 29 is a spring 86 which acts between the head 85 and the top wall of the cavity to force the pin 8% downwardly. The downward movement of the pin 8% is stopped by a nut 8'?
- the head 85 is arranged directly over an upwardly extending projection 89 on the pivot-ed arm 9 whereby when the lever arm 29 is lowcred, the head will engage the projec tion 87 and force it and the pivoted member 9 downwardly with a yielding pressure, for a purpose hereinafter explained.
- the head 85 may be adjusted toward or from the projection 87, as desired.
- a look nut 88 is provided on the upper end of the pin 84 to be screwed against the nut 87 to lock it in place after adjustment.
- the staple setting anvil 22 has a round pin like extension 90 formed thereon which enters a similarly shaped opening in the bracket 23 and which is firmly held therein by a set screw 91 screwed into the bracket 2% and engaging the extension 90.
- This construction provides a very convenient means for adjustably securing the anvil 22 to the bracket
- the extension 90 may be moved longitudinally within its opening in the bracket to adjust the anvil 22 laterally with 'es 'iert to the staple driver 27 and staple guiding channel 19; and by rocking the anvil 22 on the axis of the-extension 90 the grooved top of the anvil may be adjusted forward and back with respect to the staple driver the spring 16.
- the pulley 52 is driven constantly from a suitable source of power and the parts of the machine rest normally in the position shown in the drawings while the pulley 52 rotates idly on the shaft 410.
- the work to be stapled is placed upon the anvil 22 and the bar 83 is depressed against the action of the spring 82 by the aid of a foot pedal or other suitable device, and immediately after the depression thereof it is released.
- the bar 83 rocks the link 75 on its pivot 76 and thereby causes the link 75 to pull the pivoted member 9 down until its staple guiding projection 21 rests upon the work placed upon the anvil 22 and prevents further downward movement of the member 9.
- the bar 83 may be released practically immediately after it has been depressed sufficiently far to bring the controlling part 63 into engagement with the stop lug 69.
- the spring 82 in tending to raise the link 7 5 pulls the arm 67 into engagement with the periphery of the flange 65 of the member 39 and prevents the return of the controlling part 63 to its normal position until the driving member 39 makes a complete revolution, whereupon the spring 82 pulls the part 63 back to normal position and causes the arm 67 to engage the shoulder 66 and prevent further turning ofthe driving member 39 just as the dog 56 is moved by the cam 62 from engagement with a notch 55 in the driving pulley 52.
- the eccentric 38 depresses the staple driver 27 from the position illustrated, as the high part of the eccentric 38 passes over the shaft a0, then raises the staple driver to its highest position above that illustrated, as the high part of the eccentric 38 moves down to a position beneath the shaft 40, and then depresses the staple driver 27 to the position illustrated, as the eccentric 38 comes to rest with the driving member 39.
- the staple driver 27 drives the staple 13 down through the channel 19 and through the work upon the anvil 22 and into engagement with the anvil causing it to turn the staple prongs inwardly and clench the same.
- the pull of the spring d8 upon the lever 35 should be varied when the thickness of the work varies to any appreciable extent, and also staples having prongs of varying lengths should be used, for greatly varying thicknesses of work; the length of the prongs being consistent with the thickness of the work to provide the proper length o1 prongs which penetrate below the work for clenching and the pull of the spring 48 for stapling thick work being greater than for stapling thin or delicate work, so that the stapling pressure against the driver 2? will not yield before the thick work has been properly penetrated by the staple, and so that the yielding pressure of the staple driver will not be too great for thin or delicate work.
- This desired ieldin aressure or pull or the spring l8 may be varied or regulated by -moving the spring connecting member -7 toward and from the lever fulcrum 36, as previously explained.
- the spring 82 does not raise the pivoted member 9 to the position illustrated until the staple has been set in the work and the lever arm 29 is raised to elevate the staple driver 27 due to the friction between the staple drivingand the parts of the member 9 which guide them.
- the pivoted member 9 rises to the position illustrated with the lever arm 29 when it elevates the staple driver 2'? within the pivoted member 9, the upward movement of the staple driver 2'? within the member 9 causing it with the aid of the spring 82 to the member 9.

STAPLING-MACHINE.
Application filed November 1, 1919.
To all whom it may concern:
Be it known that I, ELwooD H. M1011- ENER, a citizen of the United States, residing at 1V oodlynne, in the county of Camden, State of New Jersey, have invented certain new and useful Improvements in Stapling- Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
T his invention relates to improvements in staple setting machines wherein are employed a staple setting anvil, a member movable toward and from the anvil and provided with staple guiding means and a staple driver adapted to cooperate with the staple guiding means and the anvil to set a staple in work placed upon the anvil.
An object of the invention is to provide a novel and advantageous means for con trolling and actuating the staple driver under a pressure which will yield during the staple setting operation to compensate for different thicknesses of work placed upon the anvil; and which may be adjusted to provide different degrees of light yielding pressure for line or thin or delicate work and different degrees of heavy yielding pressure for thick or coarse work to compensate for slight differences in thicknesses in work being stapled by staples having prongs of uniform length, and to provide the desired different yielding aressures for different staples having prongs of varying lengths for work of greater differences in thickness. Another object of the invention is to provide a novel arrangement of parts which will prevent more than one staple at a time from being presented from the staple magazine to the staple driver between it and the anvil; and a further object of the invention is to provide a novel and advantageous means for adjustably supporting the staple clenching anvil.
With the above and related objects in view the invention consists in the novel construction, combination and arrangement of parts hereinafter described and claimed.
In the accompanying drawings illustrating my invention,
Figure 1 is a. side view of a stapling machine embodying my invention.

Fig. 11 is a vertical section through the forward end of the pivoted member carrying the staple driver, on line 1l-11 of Fig. 3.
Fig. 12 is a detail in section of the staple setting anvil and a part of its supporting bracket.
Referring to the drawings, the frame of the machine comprises a standard 2 provided on its upper portion with a forwardly extending arm 3 and on its lower portion with base projections 6 adapted to be secured to a suitable table 7 for supporting the machine.
Pivoted at 8, to the standard 2 is a memher 9 which extends forwardly from its pivot laterally adjacent to but spaced from the frame arm 3. The outer side of the member 9 is grooved forming a magazine 10 for the staples, and the magazine 10 is provided with a longitudinally-extending guiding rib 12 embraced by the row of staples 13 which is adapted to be fed forwardly thereon toward a wall 1 1 which is opposite to and spaced from the forward end of the rib 12 a distance equal to the thickness of a staple. The row of staples 13 is fed toward the wall 14 by a suitable follower 15 which is slidably fitted to the magazine 10 and attached to one end of a spring 16 which extends around a pulley 17 and through an opening in the member 9 to a lug 18 on the opposite side of the memher 9 to which the other end of the spring 16 is attached, the spring 16 acting to move the follower 15 and row of staples 13 toward the wall 14.
The space between the wall 14 and the forward end of the staple guiding rib 12 forms part of a channel 19 which extends up and down transversely to the rib 12 and through upwardly and downwardly extending projections 20 and 21, respectively, on the forward end of the member 9. The projection 21 is located above a staple setting anvil 22 which is carried by a bracket 23 secured to the forward end of the frame arm 3; and the member 9 is adapted to be moved on its pivot 8 to move the bottom of the projection 21 toward and from the anvil 22 to clamp the work to be stapled between the anvil 22 and the projection 21 during the stapling operation and to raise the projection 21 from the anvil 22 to permit the removal of the stapled work and the insertion of new work to be stapled. When the pivoted member 9 is raised, its upward move ment is limited by a projection 24 thereon engaging an adjustable screw 25 which is carried by a lug 26 on the standard 2. By adjusting the screw 25 the extent of the upward movement of the member 9 may be nicely regulated.
A staple driving plate 27 is fitted to slide in the channel 19 toward and from the anvil 22. The staple driver 27 is secured to and extends downwardly from a block 28 which is fitted to slide within the projection 20, and the sides of the block 28 are pivotally connected to the bifurcated end of the forward arm 29 of a lever 30 which embraces the upwardly extending projection 20 of the pivoted member 9. The lever 30 is fulcrumed, at 31, within the bifurcated upper end of a link 32 whose lower end is pivoted, at 33, to the standard 2. The end of rearward arm 34 of the lever 30 is bifurcated and embraces and is pivoted, at 50, to the forward portion of a lever 35 which is fulcrumed at 36 on the upper end of an arm 37 which is also embraced by the lever arm 34. The lower portion of the arm 37 surrounds and is fitted to an eccentric 38 forming part of a driving member 39 which is mounted to turn freely on a shaft 40 projecting fixedly from one side of the standard 2. One end of the shaft 40 is inserted into a split boss 41 on the standard and firmly clamped therein by a screw 42 which is arranged to draw the sides of the split boss 42 together. The lever 35 has an arm 43 which extends rearwardly from its fulcrum point 36 and which has a longitudinal slot 44 formed therein. The bottom wall of the slot 44 has spaced notches 45 for the reception of a pin 46 which extends transversely through the slot 44. The outer ends of the pin 46 enter the sides of a split adjusting member 47 which embraces the bottom por tion of the lever arm 43, The adjusting member 47 is connected to the upper end of a spring 48 whose lower end is connected to a projection 49 on the lower portion of the arm.37. The spring 48 tends to draw the lever arm 35 and its fulcrum 36 toward the eccentric 38 and thereby tends to raise the lever arm 34 which is pivoted to the lever 35 forwardly of its fulcrum 36, for a purpose hereinafter explained.
From the construction just described, it will be understood that when the driving member 39 is rotated upon the shaft 40 the eccentric 38 will raise and lower the arm 37 and lever 35 and thereby rock the lever 30 and reciprocate the block 28 and staple driver 27.
Mounted to turn loosely on the shaft 40 between the driving member 39 and a collar 51, fixed on the outer end of the shaft, is a pulley 52 which is adapted to be constantly driven in the direction of the arrow in Fig. 1 from any suitable source of power. The inner end of the pulley hub 53 has circular cavity 54 formed therein into which one end of the driving member 39 extends. The pulley hub 53 is adapted to rotate around the end of the driving member 39, and the hub 53 has a series of spaced outwardly-extending notches 55 which interrupt the circular Wall of the cavity 54. The notches 55 are adapted to be entered by the free end of a dog 56 which is pivoted, at 57, to the driving member 39 and which is fitted to a slot 60 in the member 39 to move inwardly and outwardly on its pivot 57. Arranged within an opening in the dog 56 is a spring 61 which presses against the member 39 and dog 56 and tends to force the free end of the dog outwardly. Normally the dog 56 is held in its innermost position, as shown in the drawings, against the spring 61 by a cam 62 formed on a controlling part 63 which is pivoted, at 64, to the standard 2. Vi" hen the part 63 is rocked on its pivot 64 in the direction of the arrow in Fig. 4, to move the cam 62 from beneath the dog 56, the dog 56 will be freed and forced by the spring 61 against the circular wall of the cavity 54; and, thereafter, the dog 56 will be forced by the spring 61 into the first notch 55 of the constantly rotating pulley 52 which passes it. Immediately upon the entrance of the dog 56 into the notch 55, the driving member 39 will start to rotate with the pulley 52 and will continue to rotate therewith until the controlling part 63 is returned to the position shown in Fig. 4, as will be hereinafter explained. The driving member 39 has an outwardly extending ring or flange 6 formed thereon and cut away to form a shoulder 66to be engaged by a projection 67 on the controlling part 63 to stop the rotation of the driving member 39 when the controlling part 63 is returned to its normal position. The controlling part 63 has an arm 68 formed thereon which is adapted to engage a lug 69 projecting from the standard 2 to stop the further movement of the part 63 after it has been moved in the direction of the arrow sufiiciently to cause the cam 62 and projection 67 to clear the dog 56 and tooth 66, respectively, and thereby permit the driving member 39 to be rotated by and with the pulley 52. When the controlling part 63 is moved to permit this operation the projection 67 clears the shoulder 66 before the cam 62 clears the dog 56 and permits the dog to enter a notch 55 in the pulley hub 53, so that the driving member 39 will be free to rotate immediately the dog enters a notch 55.
To prevent the driving member 39 from being turned backward, I provide it with an opening or cavity 70 having a dog 71 slidably fitted therein. The dog 71 and the adjacent wall of the opening 70 are made square in cross section to prevent the dog from turning; and the dog is provided wlth an inwardly projecting pin 72 which is encircled by a sprin 73 which presses the dog 71 against the frame boss 41. The outer end of the dog 71 is beveled as shown and enters a similarly shaped notch 74 in the frame boss all after each revolution of the driving member 39 and thereby prevents backward turning thereof. lVhen the driving membe 39 is turned forwardly by the pulley 52, the dog 71 is forced by its beveled end out of the notch 74 against the action of the spring 73.
The pivoted member 9 is adapted to be lowered toward the anvil 22, and the controlling part 63 is adapted to be moved in the direction of the arrow to start the actuation of the driving member 39 by operating a link ?5 which is pivoted, at one end at 76, to the controlling part 63 and which extends forwardly therefrom. The forward end of the link 75 is pivoted, at 77, to the lower portion of a link 78 whose upper end is pivoted, at 80, to the member 9. The link 78 extends downwardly from its pivoted connection with the link 7 5 and into a guiding slot in a lug 81 on the standard 2. The link 75 is held normally elevated in the position shown in the drawings by a spring 82 the lower end of which is connected thereto and the upper end of which is connected to a lug on the standard 2. In holding the link 75 up in the position illustrated, the spring 82 holds the pivoted member 9 elevated and holds the controlling part 63 in position to prevent the rotation of the driving member 39 by the pulley 52. The link 7 5 is adapted to be depressed by a suitable foot pedal, not shown, connected to a bar 83 whose upper end is pivoted to the link 7 5. The relation of the connections just described is such that when the bar 83 is moved downwardly, the first operation effected thereby 'will be to rock the link 75 on its pivot 76, without moving the controlling part until the link 75 pulls the pivoted member 9 down to engage its projection 21 with the work upon the anvil 22 to be stapled and thereby stop further downward movement of the member 9. When the downward movement of the member 9 is thus stopped the further downward movement of the bar 83 will rock the link 75 on its pivot '77 and move the controlling part 63 in the direction of the arrow until it engages the stop lug 69 and prevents further downward movement of the bar 83 and releases the driving mem- 361' 39 and permits the dog 56 to enter a notch 55 of the driving pulley 52 to start the rotation of the driving member 89 by and with the pulley 52. If the bar 83 be depressed to effect the operations just described and released immediately after the member 39 starts to rotate, the spring 82 will return the controlling part to normal position and the controlling part will stop the rotation of the driving member 39 after the pulley 52 turns it a completerevolution.
Slidably fitted within an opening in the lever arm 29 is a pin 84C having a head 85 on the lower end thereof; and encircling the pin Bet and housed within a cavity in the lever arm 29 is a spring 86 which acts between the head 85 and the top wall of the cavity to force the pin 8% downwardly. The downward movement of the pin 8% is stopped by a nut 8'? which is screwed on to the upper end of the pin 84 and engages the top of the lever arm The head 85 is arranged directly over an upwardly extending projection 89 on the pivot-ed arm 9 whereby when the lever arm 29 is lowcred, the head will engage the projec tion 87 and force it and the pivoted member 9 downwardly with a yielding pressure, for a purpose hereinafter explained. By adjusting the nut 87 the head 85 may be adjusted toward or from the projection 87, as desired. A look nut 88 is provided on the upper end of the pin 84 to be screwed against the nut 87 to lock it in place after adjustment.
The staple setting anvil 22 has a round pin like extension 90 formed thereon which enters a similarly shaped opening in the bracket 23 and which is firmly held therein by a set screw 91 screwed into the bracket 2% and engaging the extension 90. This construction provides a very convenient means for adjustably securing the anvil 22 to the bracket By loosening the screw 91 the extension 90 may be moved longitudinally within its opening in the bracket to adjust the anvil 22 laterally with 'es 'iert to the staple driver 27 and staple guiding channel 19; and by rocking the anvil 22 on the axis of the-extension 90 the grooved top of the anvil may be adjusted forward and back with respect to the staple driver the spring 16. The pulley 52 is driven constantly from a suitable source of power and the parts of the machine rest normally in the position shown in the drawings while the pulley 52 rotates idly on the shaft 410. The work to be stapled is placed upon the anvil 22 and the bar 83 is depressed against the action of the spring 82 by the aid of a foot pedal or other suitable device, and immediately after the depression thereof it is released. During the initial downward movement of the bar 83 it rocks the link 75 on its pivot 76 and thereby causes the link 75 to pull the pivoted member 9 down until its staple guiding projection 21 rests upon the work placed upon the anvil 22 and prevents further downward movement of the member 9. The engagement of the projection 21 with thework also prevents further downward movement of the pivoted end 77 of the link 7 5; and, therefore, the continued downward movement of the bar 83 causes it to pull the pivoted end 76 of the link 7 5 downwardly and thereby rock the controlling member 63 on its pivot 64 in the direction of the arrow in Fig. 4 until it engages the stop lug 69 and prevents further downward movement of the bar 83. When the controlling part 63 is thus moved its arm 67 is first moved outwardly to clear the shoulder 66 to unlock or release the member 39; and, immediately thereafter the cam 62 clears the dog 56 and it enters one of the notches 55 in the hub of the rotating pulley 52, connecting the driving member 39 thereto and causing it to turn therewith. As the dog 56 enters a notch in the pulley 52 almost immediately upon being released by the cam 62, the bar 83 may be released practically immediately after it has been depressed sufficiently far to bring the controlling part 63 into engagement with the stop lug 69. As soon as the driving member 39 starts to turn with the pulley 52 and the bar 83 is released, the spring 82 in tending to raise the link 7 5 pulls the arm 67 into engagement with the periphery of the flange 65 of the member 39 and prevents the return of the controlling part 63 to its normal position until the driving member 39 makes a complete revolution, whereupon the spring 82 pulls the part 63 back to normal position and causes the arm 67 to engage the shoulder 66 and prevent further turning ofthe driving member 39 just as the dog 56 is moved by the cam 62 from engagement with a notch 55 in the driving pulley 52. It willbe observed that when the driving member 39 is at rest, the position of its eccentric 38 is such that the staple driver 27 is about midway of its stroke, crossing the feed line of the row of staples 13 in the magazine 10, and that a staple 13 is in the channel 19 beneath the driver 27 the staple 13 having been moved there from the row 13 by the driver 27 during its downward movement just before the completion of the turning of the driving member 39 of its last previous revolution. Now, when the driving member 39 turns a revolution, as above described, the eccentric 38, through the arm 37 and levers 35 and 30, depresses the staple driver 27 from the position illustrated, as the high part of the eccentric 38 passes over the shaft a0, then raises the staple driver to its highest position above that illustrated, as the high part of the eccentric 38 moves down to a position beneath the shaft 40, and then depresses the staple driver 27 to the position illustrated, as the eccentric 38 comes to rest with the driving member 39. During the downward movement of the staple driver 27 from the position illustrated, it drives the staple 13 down through the channel 19 and through the work upon the anvil 22 and into engagement with the anvil causing it to turn the staple prongs inwardly and clench the same. During the reverse or upward movement of the staple driver 27 to its highest point, its lower end passes the top of the rowof staples 13 in the staple magazine 10, permitting the spring 16 to feed the'foremost staple of the row 13 up against the wall 14 and beneath the bottom of the driver 27, so that whenthe driver 27 is moved down to the position illustrated it will move the foremost staple of the row 13 down to the position previously occupied by the staple 13 for a succeeding stapling operation. It will thus be seen that a staple will be set in work placed upon the anvil 22 each time the bar 83 is depressed to permit the driving member 39 to turn a complete revolution. During the setting of a staple, the downward movement of the staple driver 27 to effect the same is arrested when the top bar of the staple connecting its prongs engages the top of the work placed upon the anvil 22, and this takes place before the high part of the eccentric 38 reaches a position directly over the shaft 40 and before the eccentric arm 37 com pletes its upward movement. It will be understood, therefore, that as the arm 37 completes its upward movement it will raise the fulcrum 36 of the lever 35 while the staple driver 27 and its actuating lever 30 are thus arrested, causing the lever 35 to rock on its fulcrum 36 against the action of the spring 48 in a manner to cause the staple to be set by a yielding pressure and to compensate for varying thicknesses within limits in the work placed upon the anvil. To obtain the best results, the pull of the spring d8 upon the lever 35 should be varied when the thickness of the work varies to any appreciable extent, and also staples having prongs of varying lengths should be used, for greatly varying thicknesses of work; the length of the prongs being consistent with the thickness of the work to provide the proper length o1 prongs which penetrate below the work for clenching and the pull of the spring 48 for stapling thick work being greater than for stapling thin or delicate work, so that the stapling pressure against the driver 2? will not yield before the thick work has been properly penetrated by the staple, and so that the yielding pressure of the staple driver will not be too great for thin or delicate work.
This desired ieldin aressure or pull or the spring l8 may be varied or regulated by -moving the spring connecting member -7 toward and from the lever fulcrum 36, as previously explained.
/V hen the lever arm 29 is moved down to operate the staple driver 2'? to set a staple, the head 85 of the spring pressed pin 8% engages the projection on the pivoted memher 9 and holds the projection 21 of the member 9 down upon the work being stapled with a yielding pressure.
are? the bar 83 has been depressed and released to eii ect a stapling operation, as previously described, the spring 82 does not raise the pivoted member 9 to the position illustrated until the staple has been set in the work and the lever arm 29 is raised to elevate the staple driver 27 due to the friction between the staple drivingand the parts of the member 9 which guide them. After the staple has been set, the pivoted member 9 rises to the position illustrated with the lever arm 29 when it elevates the staple driver 2'? within the pivoted member 9, the upward movement of the staple driver 2'? within the member 9 causing it with the aid of the spring 82 to the member 9.
