' proved means for mounting and operating a hinged member, such as a cover, as by a rocking movement imparted to an associated member, such as a receptacle or a platen served by the Referring at first to Figs. 1 to 4 inclusive, iii is a'rectangular flat base on which is plvotally’ mounted a rocking platen lí. Said platen con sists of a frame which may be stamped out of cover. sheet metal and is formed with a table or plat ' - ' A further/object is to hingedly associate one or more leaves with such a hinged member or form I2, sides i3 provided with iulcrum points it `supporting it on the base and located nearer to cover and its operating means in such manner that a leaf or leaves may be selected for swinging 15 movement with the cover, or for exposure by the cover or byan overlying leaf, through the appli the front than to the rear end of the platen, a ‘ downwardly extending lip‘ i5 substantially in the plane of the fulcrum points, leaving a trans- ` versely elongated aperture i6 in the table, and . ilexibly or hingedly anchored to the base by a glued .strip l1 of fabric, an elevated transverse edge member I8 at the rear end of the platen cation of pressure at a selected point. An additional object is to provide an improved hinge connection or binding of an accordion type between adjacent edges of a platen and cover, or adapted to act as a cover stop and separated from u ' the forward edge of the table I2 by a transverse of a stack 'of leaves, or one or more leaves and aperture i8, and a pair of short leg members 2li a cover, together with a suitable mounting, in order that said cover or an outermost leaf or leaves may separate from adjacent ones at the for supporting the rear end of said platen upon the base. Glued to the upper side of the table l2 is a u hinged edge when swung to an open position. Another object is to provide a suitable form or v lowermost leaf or card ‘2l whose area is substan forms of movable back.' stop for arresting a hinged cover or a stack of leaves at an intermedi ate stage of opening, and to permit a further 30 opening when the stop ls withdrawn.

At their front or free edge, the cards 22e, 22h o Of the accompanying drawing, Fig. l is a top ,and 22c are laterally notched or cut away in suc plan view of closed apparatus embodying my in cessively increasing widths as seen in Fig. l, to vention in a preferred form, with a portion of> vexpose the leaf or card below and to provide an a hand/in broken lines, positioned‘ior applying index, such es a group of letters of the alphabet, pressure to the rocking platen on the index of the lowermost one of a stack oi cards or leaves, to , open the overlying ones ci said stack. Fig. 2 is a front edge view. Fig. 3 is a longitudinal vertical section on the 45 line 3--3 of Fig. l. . Fig. 4 is aview corresponding to Fig, 3, illus trating the mode of operation, with hinged cover on the exposed portion, relating to information which may be marked yupon the particular card. These exposed index portions constitute areas tor applying downward, ñnger pressure on a se lected card to open the stack at a desired place, as‘ hereinafter set forth, , , The described stacis of indexed leaves hingedly connected in stepped fashion and adapted to he opened at selected points by properly applied force, embodies the broad principle of the leai’ed article disclosed in my prior Patent No. ,1,420,324, 56) and leaves arrested hy the movable stop in an in termediate open position, and with a further open` position illustrated in broken lines, following re , traction of the stop, all Vmovable leaves being ‘of June 20, 1922, and is here combined ln a novely manner with operating devices and provided with raised by‘pressure applied as in Fig. 1. ‘ Fig. 5 vis a semi-diagrammatic view corres- l a 'novel hinge connection appropriate thereto, as Bonding toFig. 3, on a smaller scale, illustrating ist a modlfication.î , p will further appear; ' ’ » ' The hinge- connection or binding at the rear es s 2 2,105,696 edges of the leaves is conveniently formed by a continuous strip 24 of fabric folded into a num ber of pleats 25E, 25h, 25C, 25d respectively receiv ing the edges of the individual leaves, and each 5 glued to an upper marginal side of its corre sponding leaf so as collectively to form a stepped accordion binding which will permit a limited rearward spacing movement of any overlying card from the margin of the one below it when the stack is opened as shown in Fig. 4, this spacing movement being greatest in the case of the cover 23 and the next leaf 22a It is not essential that the strip 24 shall be continuous in the portions thereof which are glued to the leaves. 15 The rear or heel margin of the cover leaf 23 is anchored to the base I0 by a restraining strip 26 of fabric hingedly attached to said margin be tween the free and heel edg'es of the leaf‘so as to unfold away from the leaf like the side of an ac cordion pleat as seen in Fig. 4, this anchoring member being either a continuation of the strip 24 or a separate strip. Being hinged at each end, the strip 26 constitutes a double hinge binding, and each inter-leaf portion of the strip 24 is 25 similarly connected with the underlying leaf and acts therefor in a like manner. ' In the operation of this form of my invention, assuming the stack is to be opened between the lowermost card 2| or facing of the table and the 30 `one above it, so as to expose the information on said facing card or permit writing thereon, the operator presses his finger on the corner of said card as indicated in Figs. 1 and 4, thereby de pressing the forward 'end of the rocker platen 5 II and elevating its rear end. During the first part of this movement, the action of the rear corner edge 21 of the table I2, or the facing card 2l superposed thereon, pushes upwardly on the overlying'stack through the lower leaf 22“, and 40 since the rear end is restrained-by the anchor ing strip 26, the stack is caused to turn toward a vertical position around said corner edge 21 until the strip 26À has straightened out in line with the cover 23. A continuation of the tilt 45 ing movement then causes the st-rip 26 to exert a relative rearward and downward pull on the lower edge of- said coverr23 and therethrough upon the lower edges of the underlying leaves 22“, 22b and 22a, further moving said cover and leaves angularly to a more open position and spacing stack may be closed by directly handling the open portion like an open book. It will be evi dent that the stack may, in like manner, be opened between any other pair of the cards or leaves 22a, 22h, 22C, or the cover 23 alone may be opened, by pressing at the appropriate place on the indexed forward edge and holding down the lower leaf of the pair, as well as those be low it. If it is not desired to arrest the stack in an intermediate open position as indicated in full lines in Fig. 4, the back stop I8 may be omitted. When such a -stop is present, it is preferred to have it automatically retractable as by mount ing it on the rocking platen II, but that is not broadly essential and said stop may be mounted in other ways. It could also be differently at tached to the rocking platen. In the modification illustrated in Fig. 5, where in, as in >the succeeding views, the thickness of 20 parts excepting the base, >is indicated by solid lines, a certain portion of the card stack consti tuting a filler is made removable vand detachably connected with the table I2 and cover 23 re spectively by a flap 28 attached by its rear mar- ` gin to the under side of the lower leaf 22A and extending forwardly under the table through the aperture I6, and by another flap 29 flexibly con nected with the rear edge of the upper leaf 22c and adapted to be slipped into a sheath or pocket 30 on the under side of the cover 23, when said cover is opened out rearwardly to bring said pock et on top. In the modification illustrated in Fig. 6, the structure is the same as in Figs. 1 to 4 except for the omission of leaves between the table I2 and the cover 23 and omission of the bindings for said leaves. In this case a flexible binding or hinge member 24“, such as a fabric strip, di rectly connects the rear margin of cover 23 with A that of the table I2, and said cover is actuated by the rear corner edge 21 of the table to swing said cover, whose rear edge is restrained by the anchoring member 26, into an open position when the rear end of the rocking platen II is raised by depression of its forward end, as before. In or separating them at their lower edges as seen this case the upper portion of the platen is a shallow receptacle having the table I2 as its floor and-the cover 23 as its lid, adapted to receive a writing pad or other contents, and capable of ‘à variation in shape as desired. in Fig. 4. This movement is arrested by the cover 23 coming against the stop edge I8, at In the further modification shown in Fig. '7, the rocking platen is replaced by a stiff plate _ which time said cover is in an upright position 3| forming the lowermost one of a stack of leaves and cover connected and operating as previ 60 and the adjacent leaves are leaning against it. A removal of finger pressure upon the forward edge of the device will then allow the rocking platen to fall to a horizontal position and the stack to close by gravity. By applying the opening pressure forcefully and quickly removing it, the stack may be caused to flop over backwardly to a prone or substan ously described, said plate being fastened by a flexible hinge strip 32 upon the upper surface of a horizontally movable member or slide 33, upon whose forward corner edge 34 the plate 3l and superposed leaves are fulcrumed for rock ing motion. The extended rear edge of the cover sheet 23, shown in open position by a broken line in this view, coacts with a stiff strip 36 which is mounted in a. vertical plane on the rear edge of the slide 33 and flexibly connected there with at its lower edge, said strip acting as a stop gate which is rigid in one direction, causing the tially horizontal position with the platen in nor mal position as indicated in broken lines in Fig. 65 4, or, after said stack has reached the upright position shown in full lines, its upper part may be manually engaged and moved over to the broken-line position on removal of finger pres slide 33 to be pushed forwardly to the broken sure at the front. This permits writing to be 70 done on what was originally the lower side ofv line position when cover 23 is further opened ~out horizontally from the broken-line position, l the opened-out card. 'I'he stack may, if desired, the lower edge of said cover escaping past the then be closed by again pressing on the forward gate 36 at the completion of that movement.
