ACCOUNT-FILE.

Application filed February 28, 1920.

of Ontario, Canada, have invented certain new and useful Improvements in Account- Files, of whlch the following is a specification.

This invention relates to improvements in account files of the type shown and described in my prior United States Patent No. 996197 dated June 27th, 1911, in which a series of frames hinged together in the form of a hook are supported in a casing so that they may be turned up or down on horizontal axes to expose either side of each leaf, and my object is to simplify the constructions for guiding and supporting the leaves, to provide simple, strong and easily operated means for introducing or removing the bookcof leaves, and to arrange the apparatus so that books containing any desired number of file leaves, within certain limits, may be employed in any one cabinet.

I attain m'y object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which- Figure 1 is a side elevation of my improved account file, partly in section, showing the book of leaves in an approximately vertical position and the restraining bars raised;

Fig. 2 a similar view from the opposite side of part of the apparatus showing the restraining bars in their normal operative position;

Fig. 3 1; and

Fig. 1 a detail in front elevation showing the-engagement of the leaves with the restraining bars and guides; and

Fig. 5 a detail showing particularly one of the links, and projection thereon, connected to the lower corner of the front leaf.

In the drawing like numerals of reference indicate corresponding parts in the different figures.

1 is the casing suitably shaped to support the different parts. 2 are the bill-holding leaves connected together by the hinges 3 in the form of a book. The last leaf of the book is supported, by the engagement of its upper part with some'stationary part, to prevent it ti ping backward. In the preferred form secure to the upper part of a section on the line a-a in Fig.

its sides the pivot pins 4, which, when the book of leaves is in position, lie in open bearngs at each side of the casing. These bearlngs are preferably formed in the following manner so that the casing is adapted to receive books containing a greater or lesser number of leaves as may be necessary.

Bars are suitably supported in a fore and aft posltion, one at each side of the casing near its upper end. To each bar is secured a plurality of short stops 6 at different distances from the front of the apparatus. A longer stop 7 is detachably secured to each bar 5 by means of bolts 8, a plurality of sets of bolt holes for said bolts being provided 1n each bar so that the longer stops 7 may be secured to the bar to cooperate with any one of the short stops 6. \Vhen theapparatus is in use, the pivot pins 4 lie in front of the stops 7 and behind one set of the stops 6 as shown, so that when the pivot pins are raised out of the open bearings as herein after described, the leaves of the book will not tilt backward but may tilt forward.

It will be noted that the bars 5 are of angle bar section, the flanges 38 thereof extending horizontally inward forming the bottoms of the open bearings. These flanges will hold up the back leaf, by engagement with the pins at if the book is overloaded with accounts so that the weight causes the spring supported table 9 to sag a little. The

leaves are supported on the table 9, which is resiliently supported to move vertically. While any suitable means may be provided for yieldingly supporting the table, I prefer the mechanism shown. A pair of bent levers 11 are pivoted on the sides of the casing and are connected by the cross bar 12 on which are journaled roller 13 engaging the underside of the table 9. One or more coil springs are provided, each connected at one end to the lower end of one of the levers 11, and .at the other end to the casing. A second pair of levers 14 are pivotally connected to the sides of the casing connected by a cross bar 15 provided with rollers 16 engaging the under side of the table at the oppothe cross bars 12 and 15. The table is guided vertically by means of suitable projections 18, preferably formed as rollers, which enthe projections 20.

gage opposite sides of the guide bars 19, one of which is secured to the casing at eachside thereof. y c V To prevent the leaves being forced up beyond their normal operative position when either horizontal or vertical, I provide each leafat each side of its hinge with a projection 20, preferably formed as a roller. These projections are adapted to engage the under sides of the restraining bars 21 which are supported one at each side of the casing in such a manner as to be vertically adjustable, or otherwise moved from engagement with When the restraining bars are in the position shown in Fig. 2, the projections 20, when the leaves are in the upright position, engage beneath the restraining bar, while as each leaf is drawn down to the horizontal position its'projeetions move downwardly and lie behind the vertical guide bars 19. As the leaves-are turned down pressure is exerted on the vertically movable table tending to depress it as much as may be necessary to accommodate the number of leaves vided with lateral projections which are adapted to engage in front of the uide bars 19. To facilitate the engagement of the projections 20 behind the guide bars 19, and the projections 23 in front of said bars, I

provide each of the vertical guide bars 19 with the forwardly inclined upward extension 24:.

It will be noted that when the restraining bars 21 are in their normal operativeposition, they substantially meet theupper ends of the vertical guide bars 19, and the book of leaves is held in position with its pivot pins 4; lying between the pair of stops 7 and one of the pairs of stops 6. The leaves may then readily be turned up or down as may benecessary. To remove the book of leaves, it is necessary to raise the restraining bars. The table will then lift sufliciently far to raise the pivots l above the tops of the lugs 6, behind which they have been engaged. The'book of leaves is then tipped forward and the projections 20 and 23 of the frontv leaf pulled Off the inclined extensions 24 of the vertical guides,when the book is free. By a reversal of the process a book is readily placed in position. 2

While any suitable means may be provided for adjusting the restraining bars, I prefer to arrange them to slide vertically on the guides 25 and 26, which are suitably sup- Pivoted near the forward end ofeach' restraining bar is a latch 30, which latch has a pin and slot connection with the slide 28 latch may be moved into or out of position to engage a shoulder 31 formed at the lower end of the front guide 25. A coil spring 32 is connected at one end to the restraining bar and at the other end to the pin 33 secured to the slide 28, so that the tension of the spring tends to move the slide to a position for its rear end to engage beneath the lug 29 and also to cause the slide to throw the latch 30 to the position in which it engages the shoulder 31. The slide is preferably formed of sheet metal and the outer end is bent to form an inclined lug 34 forming convenient means whereby the slide may be operated or used to push down the restraining bar when it is desired to restore it to its normal operative position.

As the use of the projections23 tends to raise the first leaf at its hinged edge above the top of the table 9,1 form at opposite sides of the table raised bosses 35 adapted to engage the outer part of the front leaf when it isturned down so that the saidleaf will be held substantially parallel to the top of the table. In order that the front edge of the leaves may remain. exposed when more or less of the book is in horizontal position, the front of the lower part of the casing is cut out. and as an opening would be left when the table is an raised position, I secure to the forward edge of the table a roller curtain 36 of ordinary type, which passes around the guides 37; r

It will be noted that, as the pivot pins 4 are held in substantially fixed position, when only one leaf is up the leaf is inclined somewhat rearwardly, whereas when all the leaves are up, the front leaves are inclined somewhat forwardly. I therefore prefer to extend the sides of the casing forwardly,

position, are thus all covered, while the sides of the casing do not overlap in any way the leaves when the latter are in horizontal position.

The apparatus as shown is adapted for use so thatby the operation of the slide, the V plurality of account holding leaves hingedtogether so that they may be turned to substantially vertical or horizontal position; a. resiliently supported, vertically movable table on which the leaves are supported; pins projecting from the hinges of the leaves at each side; a restraining bar at each side movable toand from its normal position in which it is engaged by the said pins to prevent their vertical movement; and supporting means engageable by the upper part of the back leaf to prevent said leaf falling backward.

2. In an account file, the combination of a plurality of account holding leaves hinged together so that they may be turned to substantially vertical or horizontal position; a resiliently supported, vertically movable table on which the leaves are supported; pins projecting from the hinges of the leaves at each side; a restraining bar at each side movable to and from its normal position in which it is engaged by the said pins to prevent their vertical movement; a projection at each side of the back leaf of the book adjacent its upper edge; and stops, the outer faces of which are engageable by said projections to prevent the back leaf falling backward.

3. In an account file, the combination of a plurality of account holding leaves hinged together so that they may be turned to substantially vertical or horizontal position; a resiliently supported, vertically movable table on which the leaves are supported; pins projecting from the hinges of the leaves at each side; a restraining bar at each side movable to and from its normal position in which it is engaged by the said pins to prevent their vertical movement; a projection at each side of the back leaf of the book adjacent its upper edge; and bearings for said projections open at their upper side whereby when the restraining bars are raised the projections may lift out of the bearings.

4. An account file constructed as set forth in claim 1 provided with a vertical guide bar at each side of the table extending up substantially to the restraining bars, when the latter are in normal position and provided with short forwardly inclined extensions at their upper ends, the projections from the hinges of said leaves lying behind'said guide bars when the leaves are horizontal; links pivotally connected with the front leaf, one

at each side at its hinges; and. a projection on each link engaging on the front side of v the adjacent guide bar.

5. An account file constructed as set forth in claim 3 in which the open bearings for the upper projections of the back leaf are adjustable to a plurality of positions at different distances from the front of the apparatus.

6. An account file constructed as set forth in claim 3 in which the bearin for the upper projections of the back lea comprise bars suitably supported in a fore-andaft position, and a plurality of short lugs secured to said bars at different distances from the front of the apparatus.

7 In an account file, the combination of a plurality of account holding leaves hinged together so that they may be turned to substantially vertical or horizontal position; a resiliently supported, vertically movable table on which the leaves are supported; pins projecting from the hinges of the leaves at each side; a restraining bar at each side adapted to be engaged by the said pins to prevent their vertical movement; and supporting means engageable by the upper part of the back leaf to prevent said leaf falling backward.
