STAPLING DEVICE Filed April 21. 1961- 4 Sheets-Sheet 4 INVENTORS HENRY RUSK/N BY SHELDON K KOHE/V A T TORNEY 3,103,012 STAPLING DEVICE Sheldon I. Kellen, Flushing, and Henry Ruskin, Bayside, N.Y., assignol's to Swingline Inc, Long Island City, N.Y., a corporation of New York Filed Apr. 21, 1961, Ser. No. 115,062 12 Claims. (Cl. 1-3) This invention relates to a stapling device having a number of novel features. The novel features of this invention when collectively employed, are particularly applicable to that type of stapling device known as a stapling plier. These features, however, may also be individually employed.

The stapling device of this invention 'has "a number of specific advantages over conventional devices, some of which will be briefly enumerated below: i

(1) The magazine of the device is formed with an openable cover so that the staples may be conveniently dropped directly into the magazine and the follow block is automatically retractable,

(2) The actuator member of the stapling device of this invention is pivotally connected to the magazine and normally overlies the cover, which in turn is also pivotally connected to the magazine. Therefore, the device may be very easily loaded by simplyswinging the actuator away from the cover and thereafter swinging the cover away from the magazine.

(3) The coverof the magazine is of novel construction and is formed with a support portion and a driving portion downwardly movable with respect to said support portion. Between the support portion and the driving portion a wire spring member is disposed whichis in turn formed with a pair of'reverse acute angular-bends therein so as to permit proper action of the parts and, at the same time, permit proper employment-of the space provided.

(4) The staple driver of'the instant invention is formed with a holding portion and an operating portion. These portions are angularly disposed with respect to one another at an angle less than 180 degrees but more than 90 degrees so as to permit proper employment of space and effective operation of the device.

Effective means are further provided to secure the stapling driver to the remainder of the device so as to permit proper employment of the parts.

(6) The construction of the instant application is simple and economical and can be manufactured with the employment of relatively unskilled labor.

Other objects and advantages of the instant invention will become apparent by a reading of the specification.

The invention may be briefly described as a stapling machine comprising staple holding rneans, staple advancing means therewithin, staple driving means overlying the staple holding means and actuatnig means operatively connected to the staple driving means.

In the preferred modification of this invention the staple holding means comprise a magazine which is preferably manufactured with a longitudinally disposed rail therewithin, the staple advancing means consist of -a follower and spring means connected to the follower and to the cover. With this construction raising ofthe .cover will cause the follower to move rearwardly and permit simple loading of the device. A cover is *pivotally connected to the magazine and normally overlies the same and bears a staple driver at one end thereof. The actuating means, in the preferred modification, consist of an actuator member which is pivotally connected to the magazine and normally overlies the cover. The actuator and the cover are further provided with complementary latching means. The actuator may be pivoted away from the cover and 'United States Patent 0 volved in proper relationship.

3,103,012 Patented Sept. 10, 1963 the cover thereafter pivoted away from the magazine in order to permit simple loading of the device.

Where the device of the instant invention is made in the form of a stapling plier, 'a base and an anvil thereupon are provided. The magazine is normally spaced from the base. A spring is secured to said base and intervenes the magazine and base.

Referring :now to the specific form of the invention herein as set forth in the accompanyingdrawings for a detailed description thereof the stapling device '11 is formed with .a :base 12 having an anvil r 3 0 thereupon. Base 12 also bears a pair of upwardly-extending lateral magazine supporting portions 13 and the forward portions 14-ofmagazine support portions 13 are fuurther up wardly extending. A-leaf spring 31 is secured to base 12 by rivet 32. 1

A magazine :15 -is -journaled at "the rear of magazine support portions 13 of -base I2 and is secured thereto by pin 33. Magazine 15 is open and'has a longitudinally disposedrail :lfiitherewithin. A follower 17is-disposed=upon rail '16 and bears a hook portion 18 thereupon. A coil spring bears an eyelet 19 at one end thereof which is secured to portion 18 of follower 117. A cover 24 normally overlies magazine 15 and is also pivotally disposed withrespect to-rnag-azine 15. Pin 33 holds'the parts in- Cover 24 is formed with a support portion 25 and a driving portion '26. A spring 27 is formed with a pair of bifurcated lateral portions 28 which are connected to one another by transverse connecting portion 29 located at one end of spring 27. Spring 27 bears reverse angular I portions 34,35 and 36 which are located intermediate the end portions of spring 27. Connecting portion 29 of spring 27 bears against the underside driving portion 26 bears laterally disposed extensions 42. Operating portion 1 39 and holding portion 40 of staple driver 38 are angularly disposed with respect to one another at an angle of less than 180 degrees but more than 90 degrees.

. Extensions 42 of staple driver blade 38 are disposed in slots 43 which are formed within the forward portion of the driving portion 26 of cover 24-. These slots 43 are formed by providing spaced'overhanging portions 66 about driving portion 26.

In order to permit driver 38 to be inserted into slots 43 and to be held in position the upper part of portion 26 adjacent slots 43 is provided with an additional slot 44.

Support portion 25 of cover 24 bears an arcuate portion 68 which constitutes one portion of latching means. Actuator 46 also has lateral portions 67 at its forward end thereof and is pivotally connected to portions 14 of base12. Actuator 46 also bears pin 47 to which roller 45 is rotatably connected. Roller 45 constitutes the other portion of the latching means and normally bears against arcuate portion 68 as shown in FIG. 8.

Cover 24 bears a pair of projections 48 at'itsrear portion thereof which in turn are adaptedto abut against separable flanges 49 at the rear of magazine 15.

the instant invention may now be explained.

The device is loaded with staples by moving cover 24 downwardly in the direction of the arrow 69 (FIG. 1). This movement causes roller 45 to clear-arcuate portion 68 since arcuate portion 68 moves arcuately and down wardly as shown in FIG. 8 in the direction of the arrow 70.

Actuator 46 can then be moved pivotally in the direc tion of the arrow 71 shown in FIG. 6 to the position shown therein. Cover 24 can then be pivotally moved in the direction of the arrow 72 shovm in FIG. 6 so as to expose magazine 15. The movement of cover 24 to its limit of travel causes projections 48 to bear against flanges 49 which, since flanges 49 are springable, holds cover 24 in openposition. As can be seen from the instant specification, the pivotal movement of cover 24 also causes follower 17 to be moved rearwardly against spring 20. Staples are thereafter loaded upon rail 16 and cover 24 pivotally moved to its normal position above magazine 15, thus disengaging projections 48 from flanges 49. It will be noted that this movement causes follower 17 to move forwardly until stopped by the staples (not shown) now disposed over rail 16. Actuator 46 is then moved to its normal position over cover 24- whereby the complementary portions 47 and 45 mesh together and cause a latching action to occur.

The device'may now be used to apply staples to articles which are placed between anvil 30 and the forward portion 50 of magazine 15. Downward pressure on actuator 46 causes corresponding pressure on spring 31 and thereby brings the forward portion 50 of magazine 15 as close to anvil 30 as the material (not shown) disposed between said parts will permit. Further downward pres sure of actuator 46 causes driving portion 26 of cover 24 to move downwardly in the direction of the arrow'shown in FIG. 2. This downward movement compresses spring 27 and causes operating portion 39 of driving blade 38 to propel a staple (not shown) through staple discharge opening 51 in magazine 15, causing stapling to occur. During the downward movement of driving portion 26 of cover 24 support portion remains in fixed position a-fter magazine 15 abuts anvil a The release of pressure on actuator 46 causes pressure to be released on springs 31 and 27, thereby causing the parts to assume their'normal position. As is well known inthe art, since follower 17 is spring loaded, an additional staple is then placed in position forfurther driving.

The parts of the instant invention are'preferably assembled as follows:

Anvil 30 is staked to base 12 at its forward portion thereon. Rivet 32 is applied to spring 31 and base 12 so as to rivet the parts into position. Pin 47 is placed into position on actuator 46 and actuator 46 is thereafter riveted to portions 14 of base '12 by extrusions 52. Follower 17 is then slid on to rail 16. Magazine 15 is then placed into position between portions 13 of base 12. Driving portion 26 of cover 24 is thereafter obtained and holding portion of staple driver 38 is slid into position into slots 43. Spring roller 21 is then assembled to portion 26. Spring 27 is then dropped through opening 53 in portion 26 with connected portion 29 dropped through first so that connected portion 29 bears, against the inside of portion 26' Driving portion 26 is then slid within support portion 25 and end portion 37 of spring 27 is then snapped into position over the upper portion of support portion 25 so as to hold the parts in place. The entire assembly of the cover is then placed between the side portions of magazine 15 and all parts secured together by pin 33. Spring 20 is then disposed over roller 21 and secured into position upon hook 23.

The foregoing specific embod-iments of the instant invention as set forth in the specification herein are for illustrative purposes and for purposes of example only.

Various changes and modifications may obviously be made within the spirit and scope of this invention and would occur to those skilled in this art.
