IN VEN TOR. Jil/755 .7. OUJSCIN/ 4/ ,ad Arm/@Amy United States Patent Office 3,0%,53 Patented dan.. 7.6, i962 3,016,538 JULTIPLE STAPLER .lames J. (lussani, 777 th Ave., Brooklyn 32, Nfl. Filed Sept. 16, 1960, Ser. N0. 56,391 7 Claims. (Cl. 1 3) This invention relates to a powerized stapling device7 and more particularly to a multiple stapling device for driving a plurality of staples in a single operating cycle.

Still more particularly this invention relates to an irnproved powerized device wherein a plurality of stapling units in side by side relation are operated from a single impeller member, said stapler units being adjustably positioned with respect to each other.

It is known to me to provide a multiple stapler device having two or more staple driving units operated by a singie source of motive power. Such devices usually take the form of a housing having individual stapling units secured to the base thereof, and having a ixed impeller including a fixed cross bar disposed in spaced relation to and in a plane vertically above the units. When the impeller of such known units is activated, as by closing a switch, the cross bar descends, striking the driver arms of the stapler units and forcing the latter through a staple clinching cycle.

Such multiple staple driving units are faulty in one or more aspects, which faults are remedied in the improved device herein described and claimed. A problem often encountered in known multiple fastening units is a very high noise level occasioned by the fixed cross bar slamming against the plural stapler units. A further problem encountered in the use of such known devices is that the individual stapler units may operate effectively when spaced apart in one manner, yet may be ineffective and furnish inequality of clinching of staples when differently positioned.

For example, a known device employing three stapling units may operate satisfactorily where the three units are equally spaced from each other, but unsatisfactorily where two units are arranged close together and the third unit spaced apart from the other two.

Further problems in known devices relate to the relative difficulty of adjusting the spacing of the individual units.

It is accordingly an object of this invention to provide a multiple stapler device having a reduced noise level as compared with powerized multiple stapling units heretofore known.

Still a further object of this invention is to provide an improved multiple stapler having novel adjustment mechanism whereby the point of application of the effective force of the impeller may, in a measure, be varied so as to provide efficient uniform driving force for each stapling unit, not withstanding uneven or unbalanced orientation of the units with respect to each other, and assuring an equalized clinching of the work at spaced points to which multiple staples are simultaneously applied.

Still a further object of this invention is to provide a multiple stapler unit having the aforesaid advantages and which, in addition, permits facile adjustment of the spacing of the staple driving units with respect to each other.

To attain these objects and such further objects as may appear herein or be hereinafter pointed out, I make reference to the accompanying drawings, forming a part hereof, in which:

FIGURE 1 is a front elevational view of a multiple stapling device in accordance with the invention, with parts of the housing broken away to show detail;

FIGURE 2 is a magnified section taken on the line 2-2 of FIGURE l;

FIGURE 3 is a magniiied vertical section taken on the line 3 3 of FIGURE l;

FIGURE 4 is a further magnified fragmentary section taken on the line 4 4 of FIGURE 2;

FGURE 5 is a reduced plan View of the stapler device.

In accordance with the invention, there is provided a housing Iii including a base Il, side walls 12, 13 and top wall I4. The base il is provided with a laterally directed slot l5, substantially parallel with the front edge I6 of the base Il. rIhe top wall i4 is similarly formed with a lateral slot 17 (see FIGURE 5) paralleling the edge 16.

A solenoid 2.@ carried by U-shaped bracket 21 is adjustably secured to the housing lil through the medium of depending bracket 22. Brackets 22 and 2i are secured together by bolts 23, 24, the upper end of bracket 22 being formed into a flange 25 which is slidably clamped against the top wall 14 by bolts 26, 26 which pass through washers 27, 27 and slot t7 and are then threaded into complementally formed apertures 28 in iiange 2S of bracket 22.

Solenoid 2t) carries an armature or plunger Sil which extends through the core of the solenoid and is slidably journalled in legs 21a, 2lb of bracket 2.1. A cap member 3l is secured to the Lipper end 32 of plunger 3d, as by bolt 33, and expansion coil spring 34 is biased between said cap and upper leg 21a of the bracket 21, thereby serving to maintain plunger Sil normally in the elevated position in FIGURES l and 3. The lower end of plunger 30 is apertured at 3S and a rounded cross bar or yoke 36 is slidably and rotatably fitted in said aperture.

A plurality of stapler units 4d, ila, which may basically comprise standard manual Staplers, are secured to the base il in a manner to provide widthwise relative adjustment. For this purpose, bolts di are sleeved through washers 42, passed upwardly through slot i5 and secured in apertures 43 provided in the base 44 of stapler dan. End stapler 4d is similarly mounted with bolts d5 and washers 46 threaded into a cooperative aperture 47 in the anvil carrying base, except that said bolts pass through separate spaced apertures i8 formed in base il to secure end stapler dit non-slidably to the base.

It will be understood, however, that slot i5 may be extended and bolts 45 pass therethrough, if adjustahility of the end stapler it) is desired.

The driver arms 5G, 50a of Staplers 4t-tl, 40a are optionally but preferably provided with operating pads 5l, Sia. rIhe pads 5I, 51a are recessed to form longitudinal troughs 52, 52a, preferably having vertical side walls 53, 54; 53a, 54a, respectively. Rollers 55, 55a are slidably and rotatably carried on cross bar 36 and are seated in the troughs S2, 52a, respectively. The rollers 55, 55a are removably retained in the troughs 52 and 52a by U- shaped wire springs 56, 56a, secured at the center branch by bolts 57, 57a to the driver arms Se, Sa, respectively.

The end branches S8, 59, 58a, 59a of springs 56, 56a, respectively, are passed over cross bar 36 in straddling relation to rollers 55, 55a, respectively, and serve to bias the rollers tightly into troughs 52, 52a, and to provide a block against the rollers becoming unseated from said troughs.

Where adjustment of the stapler di) is desired, the bar 36 may be formed with spaced annular grooves et?, 5I (see FIGURE 1) within which end branches 5S, 5E of spring 56 may be seated.

The solenoid inipeller Ztl is actuated by temporarily connecting leads A, B thereof to a suitable source of current, to effect stapling. Any of a variety of switching devices may be employed for this purpose, the operation of such devices being well known to those skilled in the art. The solenoid in the instant device employs a switching mechanism SW, which is closed by the insertion of articles to be stapled and which may be adjusted forwardly or rearwardly with respect to the front edge lr6 of the Staplers, by manipulation of knob K, so as to permit the staples to be driven selectively at various distances from the edge of the work.

While the device has been described in connection with two Staplers 4), 40a, it will be recognized that three (as shown in phantom, FIGURE l) or more units may be employed, depending only upon the space within the housing and the size of the solenoid utilized.

When a voltage is applied across leads A, B, plunger 3i) carrying cross bar 36 is thrust downwardly. Unlike multiple Staplers heretofore known, the cross bar 36, being linked directly to the driver arms 5d, Sila of the staplers, provides quiet operation by eliminating any impact of 'the parts which is encountered in known units having a cross spaced from the driver arms.

The noise level of the device may optionally but preferably be further reduced by interposing thin pads or cushions 7d, 'lla in the base of troughs 52, 52a, respectively.

Notwithstanding the intimate association of driver arm Sila with cross bar 36, stapler 40a may be easily laterally adjusted with respect to stationary unit 40. This adjustment is accomplished by loosening bolts 4l, 4l, sliding stapler alla to the desired position, and again tightening the bolts. In the course of such movement, rollers 55a and spring lingers or branches 53a, 59a slide freely along bar 36. The constant biasing inuence of the said lingers maintains driver arm Sil biased upwardly toward bar 36 and assures that roller 55a will remain captive within the trough 52a. v

In a device employing plural stapler units, I have found that notwithstanding the positive connection of the cross bar with the individual units, it is desirable to vary the point of application of impelling torce of the plunger 30 to the cross bar 36 to assure uniform staple clinching by all units and to minimize wear. Such adjustment is provided in the illustrated embodiment by bolts 26, slot 17 and the slidable connection of plunger 3) to cross bar 36.

Thus, as seen in FlGURE l, the solenoid and plunger assembly may be adjusted from the unbalanced location (solid lines) to the balanced or centered location by merely loosening bolts 26, shifting the solenoid unit in slot 17 to the desired centered position, and subsequently retighterling the bolts. lt an unbalanced location of staples is desired, as for example if two stapler units are 'to be located near one end of bar 36 and one unit near Ythe other end, the plunger 30 should be adjusted so as to be nearer the two units, preferably at a position on the bar where the sum of the movements of upward force o the two units is exactly counterbalanced by the upward movement of the single unit, so that there is no substantial tendency for cross bar 36 to tilt with respect to plunger Sil in the course of a driving stroke.

The above described multiple stapler unit will be found to operate at a noise level far below multiple units heretoore known, due primarily to the novel connection between the cross bar and the individual units. Moreover, the noise reduction ellected by such connection is accomplished without any loss in adjustability of the stapler units to each other, to provide a variety of spacings of staples driven by the unit.

By providing an impeller assembly which is adjustable with respect to the cross bar, each stapler unit is permitted to operate at maximum efliciency and with a minimum of wear, notwithstanding unequal spacing or unbalanced .orientation of the stapler units.

Having thus described the invention and illustrated its use, what l claim as new and desire to secure by Letters Patent is:
