E. BLACKBURN LOOSE LEAF BINDER F ile d Feb. 25. 1929 lllll INVENTOR Patented July 1, 1930 PATENT oFFifcE ERNEST BL CKBURN, or MOUNT LEBANON, PENNSYLVANIA LOOSE-LEAF BI DER Application filed February 23, 1929. Serial No. 341,909.

My invention relates to looseleaf binders and has for one of its objects, the provision of a binder wherein sheets may be readily placed, without the necessity of having such 6 sheets specially punched I or shaped to permit of their attachment to the binder.

Another object of my invention is, to provide a binder which will be convenient of manipulation when placing and removing sheets. 7 J 1 Still another object of my invention is to provide a binder of generally simplified and improved formbut which'will nevertheless securely hold the sheets against displacement. Someof the forms which my invention may take are sho'wn in the accompanying drawing, wherein Figure 1 is a view of the 9 binder taken on the line 1- 1 of Fig. 2; Fig. 2 is a sectional plan View of the binder; Fig. 3 is. a view thereof looking from the right handside of Fig. 2; Fig. 4 is a view showing the binder in open position to receive sheets; Figs. 5 and 6 are plan and edge views respectively, on an enlarged scale, of one of the clips; Fig. 7 shows one of the clips in operative position with respect to one of the posts; Fig. 8 is afragmentary View of the clamping bar and plate illustrating a clip used as a gauge and a punch to perforate the edge of the paper to be inserted in the binder, and Fig. 9 is a cross sectional view showmg -a modification of the base plate of Fig. 1.

Referring to Figs. 1 to 7, the binder is provided with side cover portions 10 and 11. which are shown as of flexible material such as cloth or leather, and as integral, they.

being-composed of a continuous sheet of material that extends between a back plate 12 and a-base or angle plate 13. Aback plate cover 14-is also shown as formed of flexible material which may be sewed to form a suitable sleeve enclosing the. plate 12 and whose ends are folded in between the cover sheet 10-11 and the plate as indicated at 15. The ends ofthe plat'e12 are bent over the ends ofthe plate otherwise 13 to securely hold the plates together and to clamp the cover sheets therebetween. The base plate 13 has a pair of cars 16' struck atright-angles to one'of its sides, for the reception of pivot pins or rivets 17 upon which a hinge bar 718.1is pivotally mounted. Screw-threaded binding posts 19 extendthrough the bar 18 andhave r0,- tatable movement therein, cotter pins 20 extending through the posts in order to prevent displacement thereof with respect to the bar 18. r I M j The flange 21 of the angle-plate'13 serves as a clamping plate and has slots.-22into which the outer end of the posts 19 may ti? be moved when the binder is closed, as shown in, Figs. 1 to 3. h

A clamping bar 24 has screw-threaded engagement with the posts 19 so that when; such posts are rotated as hereinafter ex- 7Q plained, the bar will. be moved longitudinally of the posts, to clamp or release sheets 25 thatthe binder is designed to hold.

A tool or clipthat serves as a wrench for turning the posts 19. and for punching key-hole slot 29, as shown more clearly in Fig. 5. The larger portion. of theslot permits the clip to be passed over the end of one of the posts 19, and-each of the posts is 0 undercut as shown more clearly in F igs. .4

and 7, toform fiat-sided slots 30 with which the slots .of the narrowed portion of the slot 29 may engage. The clip thus serves as a stop member for holding the plate 21 against outward movement through pressure of the bar, 24 against the sheetstha't are interposed between the bar. and the plate '21. With themember 27 and the post 19 in assembled position, the member 27 9 will therefore either serve as a locking clip or a wrench as heretofore indicated.

In order to gauge and punch holes in one edge of a paper to be inserted in the binder, 5 the punch device 28 of the clips will be opened and a sheet is brought into position between the sections 27 and 28 ot' the clips with its edge abutting the hinge of the clip, as shown in Fig. 8. In this position, the holes in the paper will be properly gauged from the edge of the sheet and a downward movement of the member 28 will forcethe sheet against the end of the'post and cause a hole to be punched in the sheet. When it is desired to place the punched sheets in the hinder, the parts are swung to the position as shown in Fig. i, and the sheets 25 are stacked on the posts 1.9 against the sheets 25. The plate 13 is then swung about the pivots to'cause the outer ends of the posts 19 to lie within the slots 22 of the plate. Thereupon, a tool 28 is placed upon each of the posts 19 in interlocking engagement with the slots 30 and the posts rotated to elevate the clamping bar 24: until the sheets arefirmly clasped between the clamping bar and the flange 21 of the plate 13, as shown more clearly in Figs. 1 and 3.

The portion 28 of the tool may be" exgb tended as shown in Fig. 7 to serve as a lever for operating the member 27 with sufiicient force to efiect such rigid clamping engagement as between the bar 24: and the member 21 that the posts and their associated memhere will be rigidly held in closcd position. The member 28 'may then be folded 7 down against. the member 27. i

In Fig. 9, the plate'12 corresponding to a the plate 12 of Fig. 1, is shown as corrugated 4 or ribbed to increase the stiffness thereof. 7

It will, of course, be understood that various changes in detail and general arrangement may be made without departing from y the spirit and scope of the invention as de- 4 fined in the accompanying claims, such, for instance, as the provision of other forms'of cover members 10 and'll and't he holding means therefor, etc.
