RISER FOR STAPLING MACHINES Original Filed July 1, 1940 uuuiliiniimmin'm INVENTOR MAL/Hm 6% PAM/ram! may - AT TO RN EY.
Patented Feb. 3, 1942 Original application July 1, 1940, Serial No. 343,380. Divided and this application April 5, 194-1, Serial No. 387,005
Application April 5, 1941, Serial No. 387,005
3 Claims.
This invention relates generally to improvements in stapling machines.
This application is a division of thecopending application of William G. Pankonin, applicant herein, Serial No. 343,380, filed July 1, 1940, for Stapling machines.
The object of the invention is to provide a riser for urging the stapling arm away from the anvil arm, which is simple in construction, easy to assemble, and which will eliminate wear due to the relative sliding reaction between the various parts.
The novel features, which are considered characteristic of the invention, are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawing, in which:
Figure 1 is a view in side elevation showing a stapling machine embodying the present invention;
Figures 2 and 3 are fragmentary views in perspective showing the notches in the base to accommodate the novel riser;
Figure 4 is a fragmentary sectional view of the I novel riser;
Figure 5 is an enlarged perspective view of the riser; and
Figure 6 is an enlarged perspective view of the foot-plate associated with the riser.
Referring now to the drawing, the stapling machine generally comprises an operating or presser arm I overlying and interrelated with a magazine arm 2 and a base arm 3, which latter is adapted to support the stapling machine. These arms are all pivoted about the same axis.
The base arm 3 comprises an elongated, inverted, channel-like member. At the rearward end of the base member 3 there are provided twoparallel spaced slots piercing the upper surface thereof. A supporting bracket I2 has a web portion I3 positioned below the surface of the base arm 3 and two upwardly extending flanges extending through the slots. The web portion is spot-Welded or otherwise fastened to the base arm 3 to secure the bracket I2 in position. At the upper ends of the flanges there are alined apertures which receive the nutted pintle 4b.
The web I3 of the supporting bracket 12 is provided with an aperture. I6, the outline of which is substantially H shape, as is shown in Figure 3. The upper surface of the base arm 3 is provided with an aperture H, which is crossshaped in outline, as shown in Figure 2, and is in substantial alinement with the aperture I6. A riser housing having a crown top l8 and foot portions I9 (only one of which is shown) fits within the apertures I6 and I l and extends above the surface of the base arm 3. The foot portions I 9 engage the under side of the corners of the aperture I! in the base 3 to prevent the riser from passing completely through both apertures. Inside the riser housing there is positioned a compression spring 26 which bears against a foot plate 2|. The foot plate 2| fits within the sides of the riser housing and has offsets which engage the supper surface of the irregular edges ofthe aperture IS on the web portion of the bracket I2. The foot plate 2| is assembled by inserting one end upwardly through the apertures l6 and I1, compressing the spring 20 sufiiciently to permit the other or following end of the foot plate 2| to enter through the apertures I6, whereupon the entering end may be partially withdrawn so that the foot plate assumes the position illustrated in Figure 4. This riser has a pivoted motion permitting fore and aft movement of the crown top I8 thereof as it is compressed by the operation of the stapling machine. This prevents a frictional wear arising between the crown top l8 and the bottom of the magazine arm 2. The riser can be disassembled by moving the foot plate upwardly, compressing the spring 26, withdrawing one end of the foot plate out through the aperture I6, and permitting the other end to follow therethrough, whereupon both the riser and the spring 20 may be removed downwardly through both apertures.
Although thereare shown and described certain specific embodiments of the invention, many modifications thereof are possible. The invention is not to be restricted except in so far as is necessitated by the prior art and by the spirit of the appended claims.
I claim:
l. A stapling machine Comprising a base arm,
an operating arm and magazine arm pivoted to said base arm, and a riser member for resiliently maintaining said operating and magazine arms at a predetermined distance from said base arm, said member including a, crown topped riser housing, a compression spring in said housing, and a detachable floor plate, said housing and floor plate adapted to interlock with a notched aperture in said base arm.
2. A stapling machine comprising a base arm having slots, asupporting bracket having a web below the surface of said arm and upright flanges extending through said slots, said web having an aperture of H shape outline, said arm having an aperture of cross shape outline in alinement with said first-named aperture, a riser housing having foot portions adapted to enter into said firstnamed aperture and engage the corner edges of said second-named aperture, a compression spring in said housing, and a floor plate engageable with said spring, and housing offsets adapted to engage the edges of said first-named aperture.
3. A stapling machine comprising, a magazine arm, an operating arm and a base arm pivoted at one end of each, and spacing means positioned on said base arm and comprising a housing member mounted upon said base arm and adapted to contact said magazine arm at a specified point, said housing member being loosely associated With said base member so that upon movement between said magazine arm and said base arm said housing member will be depressed with respect to said base arm Without altering its contact point with said magazine arm.
