W. PITT PERMANENT BINDING POST Filed May 24, 1959 Patented July 16, 1940 UNITED STATES I 2,208,196 PERMANENT BINDING POST William Pitt, Elizabeth, N. J assignor to Wilson- Jones Company, Chicago, 111., a corporation of Massachusetts Application May 24, 1939, Serial No. 275,378
3 Claims. (01. 85---4) This invention relates to a permanent binding post particularly adapted for use in connection with loose leaf binders.
It is an object of this'invention to provide a simple and eificient means for permanently binding a plurality of loose sheets.' Other objects of this invention will become apparent upon reading the following description, taken in conjunction with the accompanying drawing, in which Figure 1 shows one embodiment of the invention, partly in elevation and partly in section,
with the post-members ready'to be teleseoped.
together;
Figure 2 is a view similar to Figure 1 with the post members telescoped;
Figure 3 is a view similar to Figure 1 showing another embodiment of the invention;
Figure 4 shows the embodiment of Figure 3 o with the post members telescoped.
In the drawing, the reference numeral 2 indicates a female post member into which a male post member 3 is adapted to be telescoped. Both post members are provided with suitable heads 4 and 5 adapted to bear against sheets impaled on the post. A stiff resilient wire 6 is rigidly secured to the male post member 3 and projects beyond the end of the member 3 which is adapted to enter the open end of the female post member 2. The preferred manner of securing the I wire to the member 3 is to provide a longitudinal groove along the outer surface of the member. The wire is positioned in the groove and the sides of the groove are then peened over the wire to hold it securely. The wire 6 is bent at an acute angle 1 so that its free end 8 is positioned outside the area defined by the cross section of the male post member 3 at a point between the bend 1 and the entering end of the post member 3. The end 8 is cut so as to provide a sharp surface. The wire 6 is sufficiently resilient so that when the post sections are telescoped the bent end will freely enter thetubular portion of the female post member. The sharp edge of the end 8 will bite into the wall of the female post member to prevent movement of the post members in the opposite direction.
The embodiment of the invention shown in Figures 3 and 4functions in the same manner as that described in connection with Figures 1 and 2, and differs therefrom only in the shape of the wire and the manner of securing it to the post. In this embodiment the entering end of the male post member 3' is slotted across the diameter to provide an inclined surface 9 upon which a stiff resilient wire [0 is positioned. A
longitudinal groove ll provided in the circum- .3
ferential surface of the member 3 extends from the end of the inclined surface 9 towards the headed end of the member 3'.to provide the necessary clearance for the free end I2 of the wire it. After the wire I0 is properly positioned the 10 ends of the male post member 3' are pressed together, as indicated at l3- to hold the wire In securely. As in the previously described embodiment the resilience of the wire ill will' permit telescoping movement of the post sections and the sharp end of the wire willprevent movement in the opposite direction.
Although I have described two embodiments of my invention in detail, it will be understood that the description thereof is illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of the invention. Accordingly, I do not desire to berestricted to the exact details of construction described, except as limited by the appended claims.
I claim: e
1. In a permanent binding post comprising a male section and a female section adapted to telescope together, a resilient wire secured lon- 30 gitudinally to said male section and projecting beyond the end thereof, the projecting portion of said wire being bent at an acute angle whereby its end is positioned outside the area defined by the cross section of said male section. 35
2. In a permanent binding post, amale sec tion, a longitudinally extending groove in said male section, and awire secured in said groove and projecting beyond the end of said male section, said wire being bent so as to position its free end outside the area defined by the cross section of said male section at a point between said bend and the end of said male section.
3. A permanent binding post comprising a male and a female member adapted to telescope together, and a resilient wire projecting from the
