Description

Patented Apr. 25, 1944 UNITED STAPLING MACHINE Josef Kunert, Nixdorf, Sudetenland, Germany; vested in the Alien Property Custodian Application August 7, 1940, Serial No. 351,747 In Germany July 11, 1939 1 Claim.
rIhis invention relates to a paper fastening device of the type comprising a base and a pivoted arm comprising a magazine and a magazine cover secured thereto at one end and kept at a distance therefrom by spring action when in inoperative position.
In order to permit inspection of the application of wire staples to the work and quick removal of trouble due possibly to the clogging of the staple guide it has been proposed to provide the staple magazine with a displaceable magazine cover. Devices in which the magazine and the magazine cover are interengageably constructed in such manner that the magazine cover may be readily detached or attached to the magazine are well known. All such devices are, however, open to the objection that the magazine cover or a portion thereof has to 'be taken out of its working position and returned thereto after elimination of the trouble, which opera tions are often dilicult to perform and always involve a loss of time.
My invention overcomes these diiculties by pivotally mounting the magazine cover upon the magazine and holding it in fixed operating position relative to the magazine by suitable clamping means, preferably by spring noses. According to the invention, the front portion of the staple channel or guide can be readily exposed to View by turning the pivoted arm backward until it strikes the base of the device. Continued backward movement of the pivoted arm severs the clamping connection between the magazine and the magazine cover which moves the latter away from the magazine and exposes both the magazine and the staple guide. After removal of the trouble the magazine cover and the magazine need only to be swung back until the magazine strikes the front part of the base and returns the magazine cover which is pivoted on the magazine into clamped connection with the magazine by the action of the spring noses carried by the magazine cover.
One form of the invention is illustrated in the accompanying drawing, which is a side view of the device.
The device comprises a base b provided at one end with an anvil a, and at the other end with a pair of upstanding ears b'. To the base b, with an interposed spring c, there is pivoted in the ears b a magazine d, and the base b is further provided with a longitudinally displaceable resilient work guide e. The staples g are forced in known manner by a spring-loaded slide h toward a driver i held in elevated position by a coil spring k. At the rear of the magazine d there are upwardly bent bearing ears d1 for a shaft l on which the trapezoidal shaped cover m is pivoted. The cover m has a front plate n secured thereto. The casing m is enclosed on all sides to prevent the entrance of foreign bodies. The side faces of the casing m have punched noses o which serve as stops when the casing is moved back about the shaft l. The lower longitudinal edges of the side walls of the casing m are partly bent inwardly to act as springy noses p which hold the pivoted magazine d in operating position in the casing m.
It lies within the scope of the invention to employ other means for temporarily connecting the casing and magazine. It is further possible, with out deviating from the principle of the invention, to impart a different form to the staple magazine and to suitably vary the arrangement of cover and magazine, the essential feature being only to permit temporary partial displacement between the cover and magazine.
I claim:
In a paper fastener of the type described, the combination of a base having an anvil at one end and a pair of upstanding ears at the other end; a magazine having one end pivotally mounted on the base ears, and having a pair of upstanding ears adjacent said pivoted end, and spaced forwardly of said rst mentioned ears; and a cover for said magazine having one end pivotally mounted on the magazine ears and provided at its other end with means for driving staples adapted to co-act with the anvil.
JOSEF KUNERT.
