. The principal objectsof this invention are to facilitate the "handling ofthe accounting sheets in a loose leaf binder by providing a simple and effective means for shifting the 5 relative position of one'ormore sheetsinrelation to the remainder in the binder and to provide a device which maybe operated on any typeofprongibinder. l a A A=furtherimportant objeet is to materially :10 reduce the cost of accounting binderequipment and to enable the utilization of fixed prong bindersas shift binders. r Theprincipal feature of the invention consistsinproviding a supplementary set of prong-s adapted to be temporarily mounted on the permanent prongs of the binder in sliding relationthereto to effect theshifting of-theaccounting sheets.
In the accompanying drawings, Figure, 1 is a perspecti-ve view of a'binder shownopen' and illustrating the application of my attachmentto one set of the prongs; Figure-2 is a'viewsimila-rto Figure l-show ing the attachment shifted. A -3 Figure 3 is an enl'a rged "perspective view of-a portion of myimproved attachment shown mounted on the binder prongs.
Figure 4 is van end elevation-showings. portion ofa binder with my attachment housed therein. 4 I
Figure '5 is a detail plan view of the attachment. i
In, the handling of accounting sheets in loose "leaf binders it is frequently found necessary to shift groupsof accounting sheets in relation to other groups in order to'insert extra sheets orin rearranglngthe sheets upon the removal of any sheets. This "result-has been achieved in a crude manner by'the use of transfer forks consisting of a bar having a plurality *of short prongs thereon which is placed by hand into the prong" holes "of the sheets so that the. sheets maybe lifted out of the binder and transferred to a different position. Other means have been devised in the 1 form-of hinged members "forming a per- .manent partofthebinder back which may be shifted longitudinally by sliding on a hinge 1n. a L This invention COIlSlStS 1n providlng a prong device to be placed'upon the permanent prongs of the binder and so constructed and arranged as'to be capable ofbeing shifted longitudinallyin the binder back without removal by sliding on the permanent prongs to elfectthe necessary shifting in position .of the sheets. i 1 i a y In the form of the invention herein shown a strip 1 of sheet'metal is benttransversely to conformto the arch of the curvature'of the b nder'prongs 2 and one edge of the strip is bent back to form a slip 3so that a pocket is formed between the main portion of the strip land the'lip 3. Thispocket l is adapted to receive the pointed endsof one set of the prongs of the binder andit is capableofsliding in a longitudinal direction on the set of prongs. The edge of the pocket & formed by v the turned-back lip 3 of the metal strip is perforated at regular intervals in its length which intervals correspond with the spacing of the prongs of the binder and short curved prongs are inserted into the perforations andirigi'dlyisecured inplacecto project .outwardlyfrom the set of prongs'on which the 5 strip is placed;
A block 6 is secured within the pocket formed in the metal strip insuch a position that one end thereof will engage one of the permanent prongs 2 whenthe short prongs 5 register with oneset of holes in' the sheets"? and the distance between the other 'end of this block and the next adjacent permanent "prong 2 equal to the distance between the perforatlons in the sheets so thatwhen'. the r attachment is moved longitudinally on the ends of the permanent prongs, the other end of the block willlengage the nextadjacent prong to bring the supplementary prongs into proper alignment with another set of 0 holesin thesheetsp in r a It must be seen that in placing thisattachment on'a seto-f prengsof a binder the supplementaryprongs carried thereby will, when the block (i is moved to abutone of the K permanent prongs engage or register with one set of holes and as the supplementary prong s are formed to conform with the 'c'urvature of the other prong in the adjacent set, the sheets to be transferred or shifted willslip on to the temporary prongs. Then by moving the metal strip longitudinally the sheets are carried with the temporary prongs to the other position and the sheets may then be slipped back to the permanent prongs.
It will be noted that when my device is placed on one set of prongs the ends ofthe other set of permanent prongs may be swung close up to the rounded edge of the lip 3, consequently the supplementary prongs 5 will overlap these ends and there will be no danger of any sheet becoming misplaced and as the prongs are all rounded on' the ends, when a sheet or group of sheets have been moved on to the supplementary prongs, the shift device may be moved without the necessity ofspreading the binder prongs farther apart as they will, on the movement of the shift device, readily slip underthe rounded points. r r
If it is desired to move a sheet or'sheets from the binder when this'attachment is. in place, itfis merely necessaryto open the binder backin the usual manner and the points of the supplementary prongs will be carried clear of the ends of the permanent prongs ofrwhich the sheets are desired to be removed. V a
I have shown herein a means for holding my shift attachment housed in the binder back between the curved prongs 2 and vthe hinge, but the attachment is however readily detachableftIn the structure shown, I provide small metal clips 8 which-fit over the end-edges of the binder back andtheseclips are provided with smallhooks 9 over which the loop ends of an'elastic 10 are hooked. The other-ends of the elasticloop are secured to prongs l1 which'are formed in the sheet-metal strip. 7 r
I have shown my device of' sheet metal, but itwill be readily understood that thesliding member which is adapt- .ed to-be inserted on to the ends of the permanent prongs of the binder, may be readily formed of cast metal having the temporary prongs 5 cast therein, and it will be also understood that Imay without departing from the essential features of this invention, use other means for holding the device;;temporarily 'inYthe book, or the device may be used without such holding means and be transferred from book to book as it may be required. I p
It will be readily seen that the device is extremely simple and will bevery cheap to manufacture;
