Definitions

  • This invention relates to an improved magazine for feeding staples, nails, hog rings, tacks and/or brads, and the like, into position before a suitable driver, and more specifically, to such an improved magazine which is loaded from the rear end rather than from the front, top, or bottom and difiers, in part, from other known rear end loading magazines in that there are no parts which must be removed from the magazine when it is loaded.
  • staple magazine of this invention may be used with many types of fastening devices, it has great and particular utility in conjunction with portable pneumatic staplers adapted to drive relatively long heavy duty staples and nails.
  • portable pneumatic staplers adapted to drive relatively long heavy duty staples and nails.
  • the following description and discussion are primarily in terms of pneumatic stapling guns, it is to be understood that this is not to be construed as a limitation on the invention.
  • the handle portion and trigger are generally parallel to and overlie the staple magazine. Therefore, in conventional top loading magazines, it is necessary to provide sufficient space above the magazine and below the handle and trigger so that a staple may be placed into the magazine. It will immediately be apparent that as the staple guns are improved so that they can adequately drive larger and longer staples and nails, more and more such space must be provided. This, of course, will have a direct influence on increasing the height, size and Weight of the staple gun.
  • top loading staple magazine Another disadvantage of the conventional, top loading staple magazine is that it can be loaded only with the stapler in the upright position.
  • a door or closure member In such a magazine, a door or closure member is opened, and a plurality of staples are dropped into position on a staple track. The door or closure member is then closed, and the gun is ready for operation.
  • Still another object of this invention is the provision of a staple magazine which does not require an outer housing. While the magazine of this invention can of course be shielded with an outer housing as is conventional in most presently available magazines, elimination of such a housing will reduce the total weight of the magazine assembly by as much as as well as reducing its overall bulkiness. Also, by eliminating the outer housing, the supply of staples in the magazine is visible at all times, and an operator can readily note his supply of staples before starting on any given job. This construction which does away with the outer housing also eliminates the necessity for periodically cleaning out dirt or foreign matter which in conventional stapling devices, accumulates in the magazine.
  • Another advantage of this staple magazine is the convenience of being able to partially load this magazine at any time during operation. It is not necessary to cock the staple feeder at the time of loading. The operator may wait until it is convenient for him to stop and cock the staple feeder behind the newly inserted staples.
  • Another advantage of this staple magazine is the fact that is can be very easily unloaded at any time during operation or with any quantity of staples in the magazine.
  • FIGURE 1 is basically a center, vertical sectional view of the staple magazine of this invention, also showing the basic elements of a stapling machine to which it maybe attached, with, however, some parts shown in full and other part broken away;
  • FIGURE 2 is a cross-sectional view taken along the line 22 of FIGURE 1;
  • FIGURE 3 is a cross-sectional view taken along the line 3-3 of FIGURE 1.
  • the magazine of this invention is adapted to be mounted at the base .of a stapling machine including a handle portion 10, a body portion which includes a cylinder 11, piston 12, staple driver 13, and a nose portion 14.
  • the nose portion 14 includes a staple drive track 15 into which the magazine of this invention is adapted to successively feed a plurality of staples and in which the staple driver 13 is reciprocated at the urging of the iston 12.
  • the magazine of this invention includes a staple support rail indicated generally in FIG. 1 at 16.
  • the staple support rail can behollow in construction, including a top surface 17, side walls 18 and 19, and a bottom plate 20, If desired, the staple support rail could be made out of a solid piece of stock, but the construction shown is to be preferred in view of the significantly lighter weight.
  • the staple support rail 16 will be of a width substantially equal to the inside dimension-of the crown of the staple the magazine is designed to accommodate, and the side walls 18 and 19 must be suflicient size to' accommodate the length of the staples being used.
  • the magazine of this invention can be made to a'cc o'nunodate a wide variety of staples.
  • the outer end of t-he'hollow staple support rail may be closed by means of 515mg 21 (see FIGS. 1 and 2) secured in place by any spimue'rasenin such as screws, pins or welding.
  • the end of the plug 21 will be beveled as at 22 to faeili'tate' the loading of staples thereon.
  • the nose portion 14 is provided withfain inverted U shaped opening 23 leading into the stapledr'ive track 15.
  • the front end of the staple support rjailf lfi'm'ust be aecurately aligned with this opening, so
  • the nose portion 14 is provided with a rearwardly extending tongue 25, which is adapted to bef received within the open end of the staple support rants? i
  • the rear or right hand end of the staple support rail as vilewed in FIG. must be supported below the handle portien'mef the stapling machine.
  • bracket a (shown for purposes bf illustration in FIGURE 3in practice it would be llocatied at the rear or right hand end of FIG- URE 'l as earlier mentioned) extending between the handle portionlt) and the bottom member 29 of the se ia support rail so as to leave ample room between bracket and the staple support rail so that the staplefeeder carriage may clear when drawn to its rearwas radi u,
  • FIG. 1 Parallel to overlying the staple support rail 16 is a track indicated in FIG. 1 at 26, As seen in FIG. 3, the guide, traclg 2 6 is provided with a central depending' channel 261.

  • the bottom surface of the ohannel'2 6a must be to the stapling machine; in FIGURE 1, the
  • a strip of staples is simply placed over the staple support rail 16 from the rear (the right hand side as viewed in FIG. 1) and under the guide track 26, and slid over the staple detainer spring 37; this spring 37 normally prevents the staples from falling off the staple support rail 16.
  • the staple detainer spring 37 may be formed as shown in FIG. 2, and secured to the inside of the staple support rail 16 by means of the pin 38, or other suitable means.
  • the forward end of the spring 37 is provided with a bent portion 37a extending out through the wall 18 of the staple support rail 16, and this is the member which serves to temporarily hold the staples in position until the staple feeder carriage is cocked behind them as will now be explained. (It will of course be understood that two such detainer springs can be provided if desired.)
  • Cocking the magazine is accomplished simply by grasping the staple feeder carriage 28 and moving it to the rear or right when viewed as in FIG. 1. This will tend to move any staples under the staple feeder arms 31 rearwardly until they encounter the projection 37a on the staple detainer spring. At this point, the staples will be restrained in the position indicated at 24a and the staple feeder arms 31 will be moved outwardly against theresistance of the small torsion springs 33, while the staple feeder carriage continues its rearward movement. The staple feeder carriage 28 is drawn back to the very end of the track 26,, or until the staple feeder arms 31 are beyond the end of the staples24a temporarily engaged by.
  • the staple detainer spring 37 at which pointv the staple feeder arms 31 will snap back against the sides of the staple support rail, and when the staplefeeder carriage 28. is released, will serve to feed the staples toward the nose of the stapling machine by virtue of the clock spring. 34and tape. 35.
