Description

p., 25 1956 L, A, MacEACHmQN STAPLER ACCESSORY Filed July 30, i955 United States Patent O" STAPLER ACCESSORY Landrum A. MacEachron, West DesMoines, Iowa Application July 30, 1953, Serial No. 371,300
Claims. (Cl. 1-49) My invention is a separate staple end bending anvil, hereafter referred to simply as an anvil, and a guide associated or associated with the anvil for positioning the staple driving mechanism of a magazine type stapler of the type that can be used for tacking over the separate anvil.
It is the principal object of my invention to provide an accessory for use with a magazine type stapler that can be used for tacking which will increase the scope of the work that can be accomplished with the stapler.
It is a further object of my invention to provide an accessory for use with a tacking magazine type stapler to clinch staples driven by it.
It is a further object of my invention to provide an accessory for use with Staplers that can be opened for tacking that in combination with a magazine type stapler of the type described comprises a stapling machine that will drive staples with their lengths parallel to the length of the throat of the machine.
It is a further object of my invention to provide an accessory for Staplers that can be used for tacking that will accomplish all of the foregoing objects without the need for any structural change in the magazine type stapler used.
These and other objects will be clear to those skilled in the art of Staplers.
My invention is inherent in the conception embodied in the structures recited in the claims and illustratively disclosed in the following speciiications and accompanying drawings; the latter being briefly described as follows:
Fig. l is a perspective view of my stapler accessory.
Fig. 2 is a reduced perspective view of my stapler accessory, a stapler and a pamphlet with the various units shown as arranged for use in stapling the pages of the pamphlet together.
Fig. 3 is a cross sectional view of my stapler accessory, stapler and the pamphlet shown in Fig. 2 and taken on the line 3 3 of Fig. 2. The scale used in Fig. 3 is between those used in Figs. l and 2.
Fig. 4 is an exploded perspective view of a modified form of my accessory.
Fig. 5 is an exploded perspective view of a second moditied form of my stapler accessory.
Referring to the drawings, I have used the numeral to designate the base of my accessory which may be made from any suitable material and is shown in the drawings as being of metal. Secured to the base is an anvil designated 12 having staple end bending grooves 14 which clinch the ends of the Staple after the ends have pierced the material being stapled. Above the base is the arm 16 which has a stapler guide means 18 formed at its free end. l have shown this guide means as a channel into which the end of the stapler is slipped to position it over the anvil. Staples are then driven in the customary manner. In effect what is created by the combination of my accessory and a stapler that can be used for tacking is a stapler that drives and clinches staples arranged parallel to length of the throat of the machine.
2,763,862 Patented Sept. 25, 1956 The form shown in Fig. 1 is. considered the preferred form in that the stapler is stabilized over the anvil, but asimple pointer indicating where the staple driving mech* anism of the stapler should be placed to put it over the anvil, will be operable for adult use, at least. The arm 16 may be secured to the `base in any suitable manner, spot welds being shown at 20. The arm 16 is preferably rigid with respect to lateral movement but should be flexible vertically so that it can either be forced open to insert paper if it is normally sprung closed or clamped down on the material to be stapled if it isnormally sprung open as it is shown in the accompanying illustrations, either form of construction is equally satisfactory as far as aligning the stapler is concerned. The arm may be hinged to the base if that form of construction is preferred, the spring construction being shown merely by way of illustration. It is also possible to have a. thin strip connecting the bottom of the free leg of the guide 18 to the main body of the arm 16 for greater strength. In. any event the anvil should be raised to insure tight stapling and particularly so if the strengthening strip is used under the stapler.
To use the device to staple the pages of a pamphlet such as the one designated 21 together, my accessory is slipped over the pages from either the top or the bottom near the fold that marks the center of the pamphlet. The magazine type stapler 23 is then inserted in the guide and a staple or several of them are driven in the usual manner. Obviously with my accessory a stapling machine has unlimited throat capacity. Furthermore, tubes and other inaccessible places can be stapled with the ordinary otice stapler with my accessory. Furthermore, deep Staplers, that is ones with a deep throat, are very expensive while my accessory could be manufactured and retailed for a small sum. My device may also be made much smaller than a deep throat stapler that will accomplish the same work.
The modified form of my stapler Shown :in Fig. 4 has the base 22 carrying the anvil 24 with the staple bending grooves 26 made as an entirely independent piece. Two holes 28 are provided in the base. These holes receive the pin points 30 of the guide 32 so that the guide may be properly aligned with the anvil. This form of the device is practical except for the fact that eXtra holes are made in the material to be stapled, and the Separate pieces are apt to get lost. The stapler is inserted in the guide the same :as with the form shown in Figs. l, 2, and 3..
The alternate form of the device Shown in Fig. 5 employs magnets to hold the anvil and guide in alignment. The guide 34 is provided with the magnet 36 having a north pole 38 and a south pole 40. The base 42 is provided with the usual anvil 44 having staple end bending grooves 46. A magnet 48 is secured in the base, and it has the north pole S0 and the south pole 52. The magnets are positioned so that the poles of opposite polarity are arranged over each other so the attraction will be strong. The anvil and guide each has a complementary portion of a complete magnetic circuit mounted on it. It will also be clear that one magnet and a keeper bar can be used to achieve the same end. The base and the guide should be of some non-magnetic substance such as aluminum or plastic. The magnetic unit has the adavntages of not making eXtra holes in the material to be stapled and also being self aligning. For most purposes, furthermore, it is my opinion that the form shown in Fig. l will be found to be most satisfactory.
Clearly I have invented a stapler accessory that fulfills the objects of my invention in a most ecient and ineX- pensive structure.
I claim:
1. In an accessory for use with a magazine type stapling machine that can be used for tacking; a base; an anvil on said base; an arm secured to said base at a point spaced from said anvil; said arm having a free end that extends over said anvil; and a magazine type stapling machine positioning guide formed in the free end of said arm; said arm and said base together forming a throat that extends approximately parallel to the length of said anvil, said magazine type stapling machine guide comprising a channel in said arm at least the width of a magazine type stapling machine commencing near said anvil and extending horizontally and transversely of the length of said arm undiminished in size to the periphery of said arm.
