Lambrix, Cleveland, hio, assigner to Allll/latic Cor-poration, Hudson, Ghia, a corporation of (Ehio Filed Sept. l, 1963, Ser. No. 53,519 2 Claims. (ill. 'M9-MH?) This invention relates to improvements .in paper ling devices of the type commonly referred to as the swung out arch type, constituting a mounting adapted to be afiixed to a suitable board or other carrier, and having a pair of separated impaling pins adapted to pass through perforations in papers for convenient temporary binding or storage, and whereby such papers or documents may be held in order while being readily raised and slid upwardly and around the transfer arch portions for convenient access to papers beneath.

in filing devices of this character, it is desirable that the arch elements are adapted to revolve about vertical axes and have their forward downwardly pointed ends coacting with the upper ends of the impaling pins, while being enabled to he swung simultaneously outwardly from the impaling pins, and to be similarly returned to securing position engaging the pins.

The general object of the present invention is to so construct such a device that it may be cheaply manufactured, durable in use, and convenient to operate.

A more specific object of the invention is to provide in such a filing device a novel form of connecting and actuating mechanism for elfecting simultaneous swinging or partial rotation of the arch members, and which likewise shall be simple, effective, and be capable of being.

cheaply manufactured and not likely to get out of order.

A further specific object is to so construct an interconnecting operating element engaging gear-like teeth rigid with each arch member and which shall constitute a single flat strip easily mounted in position, and so interconnected with elements at the lower stationary axis ends of the arches as to be self-guiding, and be provided with means for limiting the outward swinging movement of the arch members.

A still further object is to provide the yielding means so coacting with said interconnecting elements for operating the arches that the arches may be rmly but yieldingly held in normal securing position, and likewise be held in the spread or o-pen position by the same means, and particularly it is desired that such means shall be extremely simple and effective in operation and may be readily assembled with the coacting parts.

A still further specific object is to so design the base or carrier portion of the tiling device that it may be economically manufactured of sheet-like pressed `metal or be cast of suitable light weight and easily die cast material.

Advantageous details of my improved tiling device will become apparent in the following description which relates to the drawings, in which:

FIG. 1 is a plan view of a tiling device constructed in accordance with the present invention;

FIG. 2 is a front or edge elevation of the same;

FIG. 3 is a sectional view through the base portion taken on a plane indicated by the line 3-3 of FIG. l, and showing an impaling pin and transfer arch in elevation;

teeth and guide slot-at one end of the interconnecting slide.

Describing the present illustrative embodiment by the use of reference numerals, the base portion as shown comprises a substantially at plate 1 having its perimeter shaped to conform to a cover, as appears in FIG. 1, and having an ear 2 with a supporting opening or eye 3. Above this plate l is the top plate 5 having separated raised boss portions 6 and '7 formed to receive the lower ends of the rigidly supporting impaling pins l0 and 11. These pins may be made of hollow tubing with an enlarged bead for engaging the top of the boss and a cylindrical portion. The lower end of each pin tube is fitted tightly into an inturned socket 12, below which the tube is spread, as indicated in FIG. 3, for rmly securing these impaling pins.

The upper and lower plates may be secured together by any suitable means, such as rivets 15, and likewise may be aiixed by screws or the like to the carrier board. Holes for this purpose are indicated at 16.

The shape of both the plates of the base is elongated, and the upper or rear portion of each is offset upwardly, and the rear portion of the top plate is offset upwardly to form a housing for the operating parts and mounting of the transfer arches. The lower plate 1 is offset slightly at 3.7 1for a portion conforming to the area of the offset 18 forming said housing part of the upper plate.

-The transfer arch elements 20 and 2l have straight vertical portions, the lower ends of which are fitted into bearings 22 and 23 in the housing 18, and pass through the bearings and are fitted with the toothed partial gears and guiding elements within the housing between the portions 17 and 1S, as will presently be described.

The arch members are curved forwardly from the vertical portions and then downwardly where reduced end portions, as at 25, lit into the cutaway upper ends of the tubular impaling pins. Here, it will be seen that approximately one-half of the tubular portion is cut downwardly a short distance from the end, as at 26, to form a sto-p and receptacle for the forward swingable ends of the transfer arches.

The means for swinging the arches simultaneously from the storing portions, shown in FIGS. l, 2, and 3, to the open or tiling position, each being swung outwardly away from its companion, is indicated in the detail of FIG. 4, and 4the means for retaining the arches in `the closed and open position, respectively, will now be described.

A segmental gear and guide element, shown as having two full teeth and a side of a third, is formed rigid with the lower end of each transfer arch member. Referring to FlGS. 5 and 6, the parts shown correspond to the left end of FG. 1. On the segmental gear and guide element of the arch 2li, such teeth are shown at 3G, and the cylindrical portion is indicated at 31.

The teeth 3l? fit and coact with two or more teeth 34 formed on the end of an interconnecting flat bar 3S. vIt will be noted that there are two arms extending from the body of the bar, as indicated at 36, on which the teeth 34 are formed, and at 37 spaced therefrom and parallel to the sides, and hence to the longitudinal movement of the bar. The space between these two arms leaves a fla-t surface 3d which normally remains in contact with the cylindrical surface 3i as the attached arch makes its partial turn from closed to open position and back again. This `forms a guide for the bar, maintaining the teeth 30 and 34 in proper engaging position. This characteristic simplies the construction and avoids the difficulty of attempting to closely lit and guide a reciprocating interconnecting rack bar by guides formed on housing parts to attain the proper meshing of the actuating gear teeth.

As indicated at the left in FIG. l, the rack teeth 34 l amena? tb engage the gear teeth 3sat the side of the gear and guide 'elements toward the arch and pin 10, while at the other end of the bar 35 the teeth are at the side of the element away from the arch 21 and pin 11.

The inner end of the space between the :two arms 36 and 37, indicated at 39, forms a stop limiting the longitudinal movement of the bar and correspondingly limiting the opening movement of the arches.

The interconnecting Ioperating mechanism described i'cnds4 itself to a simple eiective resilient means -for holding the arches in the closed or open position. Spring members formed of iiat spring metal, each having au intermediate loop 40, and outwardly extending end portions 41 and 42, may engage notches formed in the ends of the housing portions and iit loosely between the portions 17 arid 18 forming the housing, while the outer end engages a notch, as at 44, in the vertical iiange at the end portion of the housing, and the other end of the spring engages a notch, such as at 45, adjacent to the teeth 3d. In fact, as shown, the end 41 is engaging the side of one of the teeth 30, while the adjacent portion provides a clearance permitting the parts to assume the position shown in FlG. 4.

The pivoting notch 44 is in longitudinal alignment with the movement of the interconnecting rack bar 35 and actually on a line passing through the axes of both of the gear and guide members and vertical parts of the arches. Thus, when the parts are in the closed positions, the spring end 41 is below the center or axis of the arch members, and the gears, and is tending to swing the for ward extensions of the arches and hold them into tight engagement with their receiving notches at the upper ends of the impaling posts 10 and 11. When the arches are swung to open position, as indicated in solid lines in FIG. 4, the portion 41 of the spring is at the other side of the line passing through Aboth the arch axes and gears, 'and thus exerts a pressure holding the arches outwardly.

It will be noted by comparing FIG. 1 and FIG. 4 that the interconnecting rack bar 35, when the arches are closed, is in a position at the right of that indicated in FIG. 4. When the arches are swung open, it will be seen that the gear teeth 34, having swung the arch 20 to the left aided by the springs, will have brought the surface 39 of the bar 35 into contact with the cylindrical portion 31 of the gear and guide element at the lower end of the member 20. When the arches are swung to closed position, engaging the posts 1u and 11., a stop is not heeded, but it would be apparent that the shoulder 39a may then contact the cylindrical part 31a (FIG. 4), as

appears in broken lines at the right in FIG. 1.

s previously indicated, the inner surface 38 of the hrm 37 'and the corresponding surface 38a at the right of FIG. 4 may each slide along the cylindrical surface of the partial gear member, assuring the proper tight engagement of the gear teeth at each end of the bar.

It will be apparent that the base and housing portions may be designed for artistic eiect as well as strength by being appropriately ribbed, and it will also be seen that the raised portion 18 of the top plate 5 and the corresponding area of the bottom plate may form a housing closely fitting the simple ilat rack bar 35, as well as conning the springs. This arrangement lends itself to most convenient construction and assemblage of the parts in the course of manufacture, as well as assuring retaining the parts in operative position, thus held against displacemeut throughout all sorts of motions to which the device may be subjected in use, shipping, etc.

It will also be seen that the mounting for the rigid impaling or paper-holding pins, as well as the bearing for the arches, may be formed with a minimum of expense, while suitable ribbing at the top portion, indicated at R, may add to the attractive appearance, and support the impaled ends of the papers.

It is to be understood that modications of details may be employed without departing from the spirit and scope of the invention as deiined in the appended claims.

Having thus described my invention, what I claim is:
