.1. seven, or
LOOSE-LEAF BINDER.
Application filed November 30, 1928. Serial 1T0. 822,825.
The present invention has to do with the binding of loose sheets and relates particularly to the'binding of such sheets in a book, having a coil spring as the binding post.
5 The obj cots-of the invention include, among others, the following:.
An improved means for attaching a binding post to a binder.
An improved means for providing an end section upon a binding post.
Unique means for associating a binding post withthe ends or ca member therefor.
. Means for availing t e flexibility and resiliency of a coil spring binding post for the purpose of securing thereto an end member.
A unique binding post.
An end member adapted to be secured to a bindingpost by friction and possessing improved means for effecting a secure joinder therebetween.
These, and such other objects as may hereinafter appear, are obtained by the construction of parts, combination of elements, and arrangement of the structural members of the device forming the subject matter of this application.
Only one form of the invention is illustrated in the accompanying single ,sheet of drawing, and in said drawing.
Figure 1 is a vertical section through a binder, the ends of the binding post bein broken away to show difierent details 0 structure;
Figure 2 is a perspective view of one of the gndmembers which is employed in the present evice;
Figure 3 is a transverse section of the post on the line 33 of Figure 1; and
Figure 4 is a transverse section ofthe post on the line 4-4 of Figure 1.
Like reference characters are used to desi nate similar parts in the drawing and in t e description of the invention hereinafter given.
ing is so popular and so highly eflicient, many firms are adopting plans or the keeping of correspondence in which they employ what ma be termed a loose-leaf binder. 'Natura y, these-binders must be of relatively low cost, sturdy, easily put together, of good mechanical structure, and not prone to pull pe- At the present time when loose-leaf binda fiat edge is provided against which the binder parts are adapted to be aligned. This edge will be considered as the back of the bound file.
Such a file is illustrated in Figure 1 where it is designated by the numeral 10. Perfora-' tions are made through such file of sheets, these being marked 11.
To bind this sheaf of sheets, a top and a bottom member or hinder, called covers, are provided. The top cover is designated 12 and the bottom cover 13.
Each of these members comprises a main body portion, and a bindin section there being a hinge therebetween, t e body bein designated 15, the binding section 16, an the huge 17. I
'lhrough the covers and particularly the binding sections thereof 16, perforations are provided.
Coil-spring binders such as are herein described may be attached to covers 12 and 13 in two ways, the difference being whether there are small erforations, or large perforations, through t ebinding section 16.
In theievent that there are small perforations through the binding section16, a stud hereinafter to be described (see Figure 2),
is driven through the binder and into the center of the coil spring. If a large perforation, namely, one such as would Permit the entire body of the sprin to be inserted thereinto, is used, the stud is riven into the sprin binding". ost much deeper than ctherwise, an so that t e head of the stud at its under surface'is adapted to impinge the end of: the coil spring.
For purposes of illustration, the binder shown in Figure 1 shows both forms of connection, one format the top and the other at the bottom.
The coil spring which comprises the binding post is designated 20, and'it comprises a plurality of convolutions of wire of considerable thickness whereby suflicient strength is obtained. Through the center of such post is an axial aperture, and which" is desi ated by the numeral 21. The shank 25 a jacent the head 24 is not barbed for a numberof 105 reasons to be later explained.
1 are of less diameter than the parts 20 and only sufliciently large to admit the oint of a stud 23, which stud comprises a ead 24 and a shank 25 having a swedged barbed portion 26. The aperture 22 in the top cover 12 may be so small that it does not freely receive the shank 25 of the stud 23, making it necessary to drive the stud therethrough against severe frictional resistance.
The lower cover 12 is attached to the spring or binding post 20 by a similar stud 23 As will be noticed, the spring 20 passes through lower section 16 and extends to the under surface of stud head 24, the stud 23 being driven into the part 20 substantially its full length.
In either instance, the spring part 20 comes into contact with the swedged barbed section 26 uaon the stud 23 and there is a frictional joinder between the stud 23 and the spring 24 brought about in the following manner:
The swedged barbs 26 are either regular or irregular projections obtained in a nail swedging barbing machine, and in which the machine is so set that concurrently upon the pressing of the barbs therein, the shank 25 of the stud 23 is deformed until it becomes elliptical, that is, somewhat flattened. Its diameter in one direction is perceptibly less than its diameter in a direction 90 degrees thereto. The swedged barbs whether regular or irregularly arranged may be in ser1es, for example, in three or four rows.
The larger diameter of the stud 23 is greater than the diameter of the aperture 21 in post 20, while the lesser diameter of the stud 23 is slightly less than the diameter of the post 20.
When the stud 23 is driven into the post 20, it forces the convolutions of the spring 20 into distorted arrangement, that is, in-
stead of being truly round or circular, some of the convolutions become elliptical because the material of the stud 23 is sufficiently hard that it will not be seriously deformed during the driving of the stud 23 into part 20. In
inserted position, the pro'ecting barbs 26 prevent rotation of the stu 23 in any direction and, of course, prevent its removal from the post 20' except by employing powerful pulling means. 1
The portion of the shank 25 between the head 24 and the swedged barbed section 26 is not necessarily deformed by the barbing machine but may remain truly circular. This permits the convolution of the post 20 above the barbed section 26 to resume their normal'position after the stud has been driven thereinto, the barbed portion 26 being several convolutions below the extremity ofthe spring 20 as is shown in the .lower part of Figure 1. This is added insurance against the removal of the stud 23 from the spring 20 for there is a frictional resistance to such removal brought about by this arrangement which, under all normal circumstances, prevents the removal of the stud 23.
