TEMPORARY BINDER MEBIBER.

Application filed November 3, 1923. Serial No. 672,486.

This invention relates to temporary book binders and some of its objects are the provision of a new and improved binder post and retainer members therefor that are simple in construction, cheap to manufacture,-

eliicient in operation, composed of a minimum of parts and that may be easily and readily assembled without the use of tools or other mechanical devices.

Another object of the invention is the pro vision of a binder post and a retainer member therefor so constructed that when the retainer member is applied to said post the 'two will automatically interlock and when it is moved to unlocked position it will be retained on said post.

Other and further objects and advantages of the invention will. appear from the following description taken in connection with the accompanying drawings, in which Fig. 1 is an end elevation of a temporary binder showing the invention in position therein;

Fig. 2 is a section on line 22 of Fig. 1 showing the retainer in position on the post;

Fig. 3 is a section on line 3-3 of Fig. 2;

Fig. 4 is a plan view of the post and retainer showing the retainer in partially removed position; and

Fig. 5 is a fragmentary view showing the post in position in the binder and with the retainer in partially removed position.

On the drawing the reference character designates a temporary binder comprising the back 11 and covers 12 and 13. A retainer strip 14 is secured to the back 11 in any suitable manner as by the stitches 15 and 16 adjacent to the covers 12 and 13 at each side of said back. The retainer strip is provided with side wings or flaps 1'7 and 18 which are adapted to extend outwardly from said back within said covers. The flaps are provided'with openings 19 which mav, if desired, be provided with eyelets 20.

The loose leaves, pamphlets and the like are adapted to be secured to said flaps 17 and 18 by means of posts 21 which are adapted to extend through openings in said leaves and through the openings in said flaps.

Suitable means are provided for retaining the posts in operative position. shown on the drawing, retainer members 22 which are provided with means for interlooking with the ends of the posts 21 are employed for this purpose. It is desirable that the retainer members be automatically locked to the posts when they are applied thereto and it is also desirable that they be applied to the posts or removed therefrom without the aid of tools or by the manipulation of additional mechanism.

As shown, each retainer member comprlses two portions 23 and 24, each of which is provided with a concave seat portion 25 which is adapted to engage the reduced por-- tion 26 at each end of said post. The reduced portions 26 may be formed by a pe ripheral groove extending about each end of said post. The portions 23 and 24 are resiliently connected together. Preferably the retaining member 22 is in the form of a disk having a diametrical slot 27 extending from one side of said disk adjacent to the opposite side thereof, the parts being united by the connecting portion 28. The distance between the seat portions 25 is slightly less tl an the diameter of the reduced portion 26 of the post whereby the resilient connecting portion 28 will resiliently hold the portions 23 and 24. in clamping position on said post. The slot 27 is enlarged at its inner endin order to increase the length of the resilient portion 28.

Due to the smallness of the size of the retaining members, they are likely to slip out of the fingers and become lost when being; removed from the posts. In order to overcome this difficulty the retainer members 22 are provided with inwardly eXtendinc; cusps or points 29 and 30 adjacent to the outer end of the slot 27. These points are preferably arranged on the periphery of the disk and the distance between the same is less than the diameter of the reduced portion 26 of the binder post. The slot is enlarged adjacent to the cusps or points 29 and 30 as at 31. The diameter of the enlarge ment 31 is greater than that of the post 21 so that the retainer may be applied to said post by first passing the upper end thereof through said enlargement 31 and then moving said retainer laterally until the seats 25 engage the reduced portion 26.

Assuming that the binder is full of leaves. the retainer members are removed by first moving them laterally so that the post 21 will register with the opening 31. The resiliency of the leaves or their tendency to spread apart will cause the flaps to move the retainer member slightly toward the end or the post whereby the outer end 32 thereot will engage the enlargement 31 as shown in Fig. l. The diameter of the end 32 ot the post being greater than the di tance between the cusps or points 29 and 30, the retainer member can not be moved further laterally and consequently is prevented from falling from the binder and becoming lost. 7

In order to remove the retainer from the position shown in Fig. t it is necessary to move the same longitudinally of said post, and since this is usually in a vertical direc tion it is necessary to firmly grasp the retainer in order to remove the same, and

consequently it is not likely to slip through the fingers and become lost.

It is thought from the foregoing taken in connection with the accompanying drawings that the construction and operation of my device will be apparent to those slrilled in the art, and that various changes in size, shape, proportion and details of construction may be made without departing from the spirit and scope of the appended claims.

I claim my invention:

1. A temporary hinder member. comprising a post having a reduced portion at one end thereof and a retainer having slot with a portion thereof formed to provide a seat for resiliently engaging said reduced portion, said seat being disengageable from. said reduced portion by a lateral movement of said retainer.

2. A temporary binder device. comprising a post having a reduced portion adjacent one end thereof, a retainer member provided with a slot extending across the same to a point adjacent to the opposite side thereof, said slot having a portion thereof formed to provide a seat for resiliently engaging said reduced portion, and cusps extending inwardly at the outer end or" said slot for preventing the loss of said member on releasing the same.

3. A retainer member for a temporary hinder post comprising a plate having a slot therein with a portion thereof tormed to provide a concave seat at each side of said slot, the outer end of said slot being provided with inwardly extending portions and with an enlargement inwardly of said por tions.

4. In combination, a binder post provided with a groove about one end thereof. a retainer member having seat portions "for engaging said groove. means for resiliently connecting said seat portions together. and means preventing the disengagement of said member from said post by lateral movement of said member.

5. In combination, a binding post member and an individual loose leal retainer member for one end of said post member, said retainer member being provided with means for resiliently clamping said post member, said means being provided with a slot having an enlarged portion whereby said retainer member may be removed from said post by first moving the same laterally in said slot and then longitudinally of said post member.

6. A post clamp in disc form, having a diametrical slot entering through one margin and terminating adjacent tile other margin, the inner end of the slot being widened to form lengthened elastic connecting ele ment for uniting the two halves of the disc, and being widened intermediate of its ends to form a post clamping seat.

7. In combination, a binder post having two diameters, a retainer comprising a disc transversely slotted through one of its margins, the slot having two enlargements of different diameters for receiving the portions of the post of different diameters.

8. In a loose lea-t binder, a plurality of posts provided with reduced portions adjacent the ones thereof, and clips provided with opposed curved seats of less distance apart than the diameter of said reduced portions, for engaging said reduced portions, said clips being provided with resilient con necting portions between said seats. said clips bei provided with slots leading to said seat whereby when said reduced portions of said posts engage in said slots they ma be made to engage seats by lateral pressure causing said seats to spread apart anl snap about .7 aid reduced portions.

9. In a loose leat bindr. a plurality of posts provided wi h reduced portions adjacent their ends, and detachable clips for resiliently engaging said reduced portions, each clip comprising a member having an open slot dividing said member into two parts connected by resilient portion. said slot being provided with an enlargement of: greater diameter ian said posts and being reduced intermediate its ends forming opposed seats of less distance apart than the diameter of said reduced portion. whereby said clips may be attached to said. posts by first moving the same lor itudinAlb. (it said posts and then by exerting later l pressure to cause said parts to separate and said seats to snap about said reduced port' "tor siliently gripping the same.
