leaves are so arranged within the binder that their lower and upper edges are staggered so that data on the upper portions ,of the leaves is Visible at all'times.

In thevisible record system of bookkeeping, it is frequently necessary to insert or remove leaves from the book,-'in which. case it is necessary" to shift some of the leaves to maintain their staggered relation. at all times. Numerous devices for accomplishing this result have been proposed which are eitherexpensive tomanufacture or do not permit of great flexibility in the insertion or removal of the leaves and this invention contemplates as an object the provision of an improved binder for use in connection with visible record. systemswhich hasgreat fleXi-' bility as to theabilitytoshift one ormorer leaves in either direction upontthe removal or IDSGIUOH-OfOlJhGI leaves. i

;.The base plate-10 has .a lazytong device mounted thereon which consists of a pair, of intersecting levers 12; and l3pivotally connected attheiri point of intersection by a, rivet or, pin; :14, passing therethrough and through the back plate, base plate and a slid; ably mounted latch or locking member 15,

tobe later described. The pin 141s riveted over the baclcplatfi and the, latch member 15 and j has a spacing collar 16 t he reon to.

maintain the lazy tongv members andqthe latch member ;in.;spacedrelation, the,apertu-re ITQfthl mBmbB i hrqughlwh the pin 14 passes being elongated to permit limited longitudinal movement of the memher, as will be later described.

A pair of smaller levers or links 18 and 19 having their outer ends pivotally connected, as at 20, is connected with the levers 12 and 13 at each side of their pivotal connection 14, by rivets 21 or the like, passing through the inner ends of the levers 18 and 19 and through the levers 12 and 13, at points equispaced from the pivot pin 14," the pivots 20 passing through elongated apertures 22 in the base plate 10 to guide their movements and insure the movement of the adjacent ends of levers 12 and 13 in the same plane, as will be readily apparent.

The ends of levers 12 and 13 are pivotally connected with a pair of sidewise, movable slide plates or members 23 and 24 by rivets 25 that pass through elongated apertures 26 in the levers 12 and 13 to accommodate the necessary play and the sidewise movements of the side plates, which are maintained parallel at all times by the lazy tong device. The ends of the members 23 and 24 are guided by upwardly and inwardly directed flanges 27 and 27 on the ends of the base plate 10, the slide members being provided with downwardly extended transverse beads or ribs 28 which space them from the mounting plate a distance equal to the combinedthickness of the levers 12 and 13 and insure the proper guiding of their extreme ends29 by the end flanges 27 and 27'.

Two series of cooperating impaling prongs or rings 30 and 31 are associated with the slide members 23 and 24, respectively, the series 30 being riveted, welded or otherwise secured, as at 32, to a mounting plate 33 secured, as at 34, to the slide member 23 and having its outer marginal edge flanged downwardly, as at 35, to provide a neat external appearance and to eliminate sharp, ungainly edges. The prongs of the series 31 are riveted or otherwise secured, as at 36, to prong mounting plates 37 pivotally secured to the slide member 24 by rivets or other means 38.

A cover and prong actuating plate 39 is disposed over the series of plates 37, being pivotally connected with each plate 37 at their ends opposite the pivots 39 by pivot pins or rivets 40, the plate 39 having apertures 41, through which the prongs 31 pass. The plate 39 is slidably secured to the slide member 24 for transverse movement therewith but longitudinal movement independently thereof by rivets 42 passed through elongated slots 43 in the plate 39, the plates 37 adjacent the pivot pins or rivets 42 being cut away, as at 44, sothat their pivotal or swivel movement is not interfered with.

The plates 24 and 33 have upwardly extending lugs or tongues 45 struck from their inner edge portions adjacent each end which are adapted to be engaged in looking recesses 46 formed in raised portions 47 of the locking member 15, the lugs 45 being of a height to permit the raised portion 47 to p ass thereover when the member 15 is moved to unlocking position. The member 15 in addition to being guided by the pivot pin 14 is guided at its ends by rivets 48 and 49, the rivet 48 being fast to the base plate 10 and having a sleeve 50 thereon to maintain the proper spaced relation between the member 15 and the binder mechanism thereunder. The rivet 49 is likewise fast to the base plate and has an expansive spring 51 coiled thereabout to normally maintain the adjacent end portion of the latch member, which is on a plane substantially even with the raised portions 47 against the head 52 of the rivet 49, the rivets 48 and 49 passing through elongated slots 53 in the member 15.

The opposite sides of slot 53 adjacent the rivet 49 have portionsstruck outwardly to provide upwardly curved projections or lugs 54 normally lying in the path of the rivet head 52 when the member 15 is in its locking position with the lugs 45 in the locking recesses 46. When it is desired to move the member 15 to unlocked position the linger-engaging portion 55 on the end of the member 15 adjacent the pin 49 is depressed to flex or bend the same suflicient to position the lugs 54 beneath the head 52 and permit movement of the member 15 to unlocked position.

The horizontal portion 56 of the guide flange 27 has notches or grooves 57 and 58 in its opposite ends in which studs or lugs 59 and 60 carried by the plates 33 and 39, respectively, are adapted to engage when the binder is closed with the ends of adjacent prongs in register so that the prongs of one series form continuations of the prongs of the other. The stud 59 and a stud 61, of which the stud 60 is a continuation, form means for facilitating the separation of the impaling prongs, and the stud 61 likewise provides means for. oscillating or pivoting the series of prongs 31 to stagger their ends with respect to the ends of the adjacent impaling prongs of the other series.

The alternate prongs of each series are provided with reduced extensions or projections 62 adapted to engage in sockets or recesses, not shown, in the ends of the adjacentprongs of the opposite series when the binder is in the normal position of use illustrated in Figure 1. hen the series of prongs 31 are diagonally disposed and the binder closed in the manner illustrated in Figure 3, the ends of the impaling prongs of one series overlap, with those of the other series, as their ends are cut on a bias, so that record sheets or leaves 63 on one series of impaling prongs may be readily slid thereover onto the impaling prongs of the other series without difliculty, the sheets in moving insertion or removal of one or more leaves.

When it is desired to elfect the shifting of one or more of the leaves, the binder is opened as illustrated in Figure land the latch member operated to release the mechanism by depressing its end and moving it to the right with reference to Figure 6. The studs 59 and 61 are then engaged and moved apart to separate the series of impaling prongs and disengage the studs 59 and 60 from their recesses 57 and 58. The stud 61 is then moved inwardly to slide the plate 39 longitudinally which oscillates or moves the members 37 on their pivots 38 to dispose the impaling prongs 31 angnlarly with respect to the impaling prongs 30,-as illustrated in Figure 2. a

a The studs59and 61 are then movedtoward each other so that the prongs of the series are disposed in staggered relation with their ends overlapping, as illustrated in Figure 3, when the transfer vof the leaves from one series of prongs to the other may be readily efiected. The binder may be locked in this position by moving the member '15. to the left with respect to Figure 6 as illustrated in Figure 3.

The stud 60 engages a finger 64: at its inner side when in the positionillustrated in Figure 2, so that the shifting of the plate 39 and consequently the prongs 31 is restrained until the parts have been unlocked by operation of, the member 15 and moved to the separated position. The horizontal portion 65 of the guide 27 has its side adjacent the plate39 cut away, asvat 66, to accommodate longitudinal sliding-movement of said plate, to angularly position the prongs 31 and the slide member 24.

After the sheets have been shifted, the

binder is unlocked, theprongs separated and the plate 39 moved to straighten the prongs 31, the binder being then closed 'to interlock the ends of adjacent prongs, as illustratedin Figure 1.

From the foregoingdescription, taken in connection with the accompanyingdrawings, it will'be readily apparent to those skilled .in the art to which an invention of the'character described apertains, that I provide a novel and improved binder specially adapted for use in connection with visible record systems'in which the impaling prongs are oscillated or rotated to effect the staggering of the prongs of one series with respect to the other for the purpose of shifting the record sheets; which may be readily locked in either normal closedposition or in closed position with theimpalingpron gs staggered, and one in whichthe binder must be unlocked and moved to full open position before the rotation of the prongs-can be efl'ected.
