rmany June 15, 1938 16 Claims. (Cl. 1-49) The present invention relates to a plier-like stapling machine, and has for its purpo to simply and rapidly free the clamp or staple channel, so that the staple feed exit point will be easily accessible from all sides. It is an obiect of the present invention to produce a plier- Iike device in which the arm operating the stamper and the member in which the staple channel is provided can be adjusted from the normal or stapling position to the open position, or vice versa; by merely overcoming wedging action without removing any part or parts, so that in this way the staple exit end of the staple carrier is easily accessible from the-front and sides.
Further objects will be apparent from the following description, taken in connection with the accompanying drawing, in which:
Figure 1 is a longitudinal sectional view of the stapling machine or tool, and
Figs. 2 to 8 are all perspective views, of which, Fig. 2 is the frame-like lower arm of the tool, Fig. 3 the upper arm, Fig. 4 the staple carrier or channel, Fig. 5 the base or anvil, Fig. 6 the stamper or rammer, Fig. 7 the staple feeder or slide, and Fig. 8 the staple rod.
The plier-like stapling tool consists of three main parts, namely, the housing'or frame-like lower arm 2 carrying or having secured therein the anvil l, the channel-like staple carrier 3 in which the staples 4 are fed by a staple feeder or slide member 5, and the upper arm 6 to which the stamper or rammer 8 is hung or mounted preferably by stamped-out lugs i, so that the stamper may swing a certain extent. The stamper 8 has one end of a tension spring 9 connected thereto at cut-out edge portions l0 (Fig. 6) and the other end of the spring is secured to a pin I2 secured in perforations I2 (Fig. 2) of the lower arm 2 and perforations l2" (Fig.3) of the upper arm 6. The stamper 8 is provided with a bent portion H (Figs. 1 and 6), which acts as a stop against the back portion H of the upper arm 6, so that the stamper. will, at. all times, be urged in correct position by the spring 9.
The pin or axle I2 interconnects the upper and lower arms 6 and 2 together, so'that one pivots on theother. A spring 13 (Fig. 1) may be provided around the pin l2 with its ends bearing on the arms 6 and 2 to urge the arm 6 counterclockwise relative to the arm 2 limited by the two projections Iii (Fig. 2) stamped into the sides of the arm 2, which'cooperate with the"cut-out portions I'I (Fig. 3) in the side parts of the arm 6 to bring the arm 6 to the full line position shown in Fig. 1. The spring is bears by one end on a projection IS in the arm 2 and the other end of this spring bears against the back portion M of the upper arm 6.
The upper arm 6 can, after overcoming the frictional clamping action of the projections IE, be swung counterclockwise around the pin l2 into the dot and dash line position 6' (Fig. 1). The stamper 8 follows every movement of the arm 6 and thus when the arm 6 is sung into the raised position 6' the stamper 8 is lifted completely out of the housing-like arm 2.
The staple carrier 3 is pivotally connected to the arm 2 by means of the pin or pivot l8 which passes through the perforations IB' (Fig. 2) in the arm 2 and the perforations l8" (Fig. 4) in the carrier 3. By means of a compression spring l9, which is preferably secured in place at one end to lug 20 (Fig. 1), stamped out from the bottom part of the arm 2, the carrier 3 is urged clockwise around the pin i8 until it contacts the stamped out projections 2! (Fig. 2) in the side walls of the arm 2. If it is desired to' move the carrier 3 to the dot and dash line position 3' (Fig. 1), frictional resistance of the carrier over the projections 2i must be overcome. Thus in the position 3! of the carrier 3 it is possible to easily reach the channel in the carrier from all sides and ends.
As seen in Fig. 1, the arm 6 is pivoted to the arm 2 at one end of the latter, and the carrier 3 is pivoted at the other end thereof.
The feed of the staples is accomplished by means of the compression spring 22 mounted on a guide rod 23 (Fig. l). The guide rod 23 is mounted in the channel of the carrier, and the staple slide 5 (Figs. 1 and 7) slides in the channel on the rod 23 which passes through a perforation in the end wall 24. The rod 23 has an enlarged end 21 (Fig. 1) at one end thereof to prevent the slide 5 from passing off or beyond its guide rod 23. At the other end of the rod 23, a bent portion 29' is provided terminating in a hook which latter engages, through the bottom of the carrier 3, against the cross-piece or bar 30.
Two upright guide lugs or plates 29 (Figs. 1 and 4) are provided on the staple feed end 28 of the carrier 3 in order to guide the stamper 8 down directly on the end staple and for this purpose the lugs 29 have outwardly bent portions arms 2 and 8 are moved toward each other around the pivot I2, the stamper 8 is guided along the inner surface of the portions 30-, and along the side surfaces of the lugs 29, and pivots around the lugs ,1 under the influence of the tension During the stapling operation, when the spring 9 during such movement. Before the stamper 8 enters the channel of the carrier 3, the latter is forced down on the papers or other matter to be stapled by means of the compression spring 32 (Fig. 1), against the operation of the compression spring l9, so that the stapling end of the carrier 3 will be adjacent the anvil I to carry out the actual stapling operation upon further movement of the arms 2 and 6. The spring 32 is preferably secured at one endon the carrier 3 by means of bent lugs 32' (Fig. 4), which grip the spring, and the other end contacts against come to permit swinging the arm 6 and carrier 3 upwardly to the dot and dash line positions 6' and 3' (Fig. 1).
It is also possible to provide the plier-like stapling tool with a base plate from which the tool is removably mounted so that the tool may be used as a hand tool, or as a table or desk appliance.
