TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 404,210, dated May 28, 1889.

Application filed October 18, 1887. Serial No. 252,693. (No model.)

To all whom. t may concern.-

Beit known that l, WILLIAM LUMLEY, a subject of the Queen of Great Britain, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Temporary Binders,of which the following is a specification.

This invention relates to improvements in temporary binders in which letter-tile indices are kept for ready reference while in con- A stant use and prior to their storing or insertion into permanent files or cases-that is,

after the index has been used a certain length of time or become too full for convenient handling, and it also relates to that class of temporary binders that are provided with a yielding clamp or holder for maintaining the index in a smooth compact form, so as to obviate the accidental loss of papers therefrom.

In binders as heretofore constructed the pin for engaging the perforated tag attached to the index-sheets has been either rigidly secured to the index-frame or else removably attached thereto, in both of which cases a fastening device for protecting the free end of such pin against the accidental removal of the index sheets has beenl employed, and which device must necessarily be operated by hand whenever the index-sheets are removed from or inserted in position in the binder.

One of the objects of this invention is to hold the index-sheets by means of a pin pivoted to the base of the binder, so as to yield laterally from its uprightposition for the insertion or removal of said sheets, and to have said pin maintained in an upright position and the sheets prevented from accidental removal by means of a spring-catch which will engage and hold the pin when pushed against it; also, to have the laterally-yielding pin before referred to actuated so that when released after the insertion or removal of sheets the said pin will automatically engage and be locked in an upright position by its retaining-catch.

Another object is to provide a temporary binder with a yielding holder for retaining the index-sheets in position actuated by devices concealed within the binder-frame and which are adapted to yieldingly retain said holder in an elevated position away from the indices, whereby the least obstruction to the insertion of the index sheets or papers is prevented, the parts protected from injury, and a better finish given to the binder as a whole.

A further object is to simplify the construction by dispensing with a number of parts heretofore employed in temporary binders, and therefore materially lessening the cost of manufacture.

A further object is to so attach the indexframe to the index-holder that While `free -to assume a limited number of angles relative to the surface of the indexsheets it cannot rotate upon its support.

A still further object is to provide means for transferring the index-sheets from the temporary binder to a permanent file without the liability of disarrangement of said sheets, whereby the eyes thereof may be easily caught upon a pin in the permanent file without trouble or the employment of skill.

I attain these objects by devices illustrated in the accompanying drawings, in which- Figure l represents a plan view of a temporary binder embodying my invention; Fig. 2, a central vertical section thereof, showing the means employed for rendering the holding-pin laterally yielding; Fig. 3, a detail side elevation, partly in section, showing the construction of the yielding index-holder; Fig. 4, a detail perspective representing the preferred form of automatic catch; Fig. 5, a modification thereof, showing the catch secured to the binder-frame in a dierent manner; Fig. 6, a detail perspective of the holding-pin and device employed for removing the indexsheets; Fig. 7, a horizontal sectional view thereof; Fig. S, a detail view showing a modification of the means employed for preventing a rotation of the index-frame; Fig. 9, a similar view of a second modification; Fig. l0, a plan view thereof; Fig. ll, a detail view of a portion of an index-sheet, showing the perforated tag attached thereto for engaging the holding-pin.

Referring by letter to the accompanying drawings, A indicates the back, and B the sides, of an ordinary binder-frame attached to a base-board, C, as usual, so as to leave one end thereof open, no drop-cover being necessary in a binder of this class, in which an index-holder is employed, the construction and IOO operation of which will he hereinafter more fully described.

To the base-board C, about the center of length thereof, but near the back, is pivoted in an upright position an index-sheet holdingpin, D, the lower end of which is turned at substantially a right angle, so as to form. a foot,E, along the under side of which lies the free end of a ilat spring, F, the opposite end 1o of which. is secured to thebase C. This spring and the foot of the pin work inv a recess, G, formed in the base C", which recess is concealed from view, preferably, by metallic covering-plate ll, upon which is cast depending r 5 ears or lugs l, constituting the bearings in which the pin l) ispivoted. It is obvious that whenever the pin, or rather the uppcrfree end thereof, is pulled forward, seas to depress the foot thereof, the `tlat spring will yield un- 2o der tension; but when the pi n is released the spring which constitutes a yielding support therefor will cause the pin to immediately return to and remain in its normal upright position until again deflected by force.

ln order to prevent the weight of the indexsheets, or any other unintentional force, from laterally deileetin g the holdi iig-pin, and thereby endanger the accidental dislodgment of said sheets, l provide a springcateh, J, secured at one end to the hack of the binder and having its opposite free end projecting over the end of the holding-pin, which latter projects through a hole, K, formed in the end thereof.

The end ot the pin has a notch, D2, formed on the rear side thereof, which is designed to receive the catch when the end of the pin projects through the hole in said catch. The tension of the spring 'F operating' to canse the 4o end of the pin to bear against the rear edge of said hole, consequently the end of the pin hooks over the catch and prevents the upward pressure of a crowded le from accidentally releasing said catch. The automatic insertion of the end of the pin in the hole may be materially aided by slightly upturning the forward edge et the spring-catch, so-that the end of the pin will pass under and elevate the same by its own action. This spring-catch 5o may vary both in form and construction, the

simplest form preferably being` shown, consisting` of a tlat spring, which may either be twisted and secured to the inner :tace of the back or may be countersunk into the top edge 5 5 thereof, all as shown in Figs. 5 and (i.

For the purpose of holding the tiled papers [lat and in a compact body secure from accident-al loss, l. provide a yielding index-holder consisting of the tiat metallic bail L, upon 6o which is mounted a rectangular wire index2 l' rame, lll, for bearing directly upon the in dex sheets. This frame may, if desired, be rigidly secured te the bail; but it preferable to pivot the same thereto, in order that the said frame may adjust itself to the di'ilering planes of the imle;\sheets, which may vary according to the tuiantity of paper tiled hetween them; but it is not desirable that this frame should be free to rotate upon its pivot, as is common in this class of devices, because the frame often turns partially or completely over when elevated above the index-sheets, and unless reversed will come down on the papers upside down, causing considerable annoyance and loss of time by its frequent :recurrence. For this reason I have connected the frame with the bail by means of otlset portions N of said frame, the horizontal parts of which pass through the holes N', formed in the bail L above the center of width thereof, in such manner that the shoulders N2 at the conjunction ot' the offset portion with the main frame will engage the lower edge of the said bail and thereby prevent a rotation of said bail upon the frame, although permitting considerable vibration thereof, for the purpose hereiubetore stated.

In Figs. S, t), and l0 are illustrated modified means for accomplishing this same object, the indeyholder in both et' these eases consisting of side arms, n., connected at their outer ends by the cross-rod l), upon which is mounted, by loopingl or winding thereon, the rectangular frame c for holding the indexsheets.

The means shown in Fig. 8 for preventing a rotation of the imlex-franic are laterallyprojecting ears d d, formed on the side arms, c, between which the said frame is conlined, but is free to vibrate, while in Figs. 9 and l0 a projecting end, c, ot' the index-frame is shown as engaging a curved slot,f, termed in a depending portion, g, of the side arm, a, which also permits the same vibration out the frame upon its pivot, but prevents a rotation` thereof. llence it will be seen that I do not desire to limit myself to the particular means herein shown and described for preventing a rotation of said frame upon its pivot, for various devices may be employed for aecomplishing the same end.

rlhe ends of the bail li have secured thereto short pivotpins t), which pass through covering-plates l?, and have rigidly secured to the opposite ends thereof short crank-arms Q, working in recesses R, formedv in. the sides ll of the binder, in which recesses also work spiral springs S, secured at one end to the crank-arm Q, and at their opposite ends lo the covering-plates l?, which latter serve the double purpose of a hearing-plate for the pivots and sprin and as covering-plates for the recesses in the sides. The side and crank arms are so disposed relative to each other and the point of attachment of the springs that the tension of said springs acting upon the arms at an angle thereto operate to maintain the index-holder in close contact with the index-sheets by exerting a downward pressure upon said arms, which pressure will continue in force until the holder and consequently the crank-arms are sufficiently elevated to bring the ends of the springs and the pivot ot the holder to a dead-center, at which time the tension ot the springs e TOO IlO

i erted in a line parallel with the crank-arms;

but when the crank end of the spring passes beyond such center the tension of such spring will come into play to yieldingly maintain the holder in its elevated position until again depressed by force, as clearly shown in Fig. 2 of the drawings.

In practice, when the binder becomes sufficientlylled, it is transferred to a permanent iile, generally provided with a fixed holdingpin for engaging the eyes of the index-sheets, and it is desirable at such a time to hold the sheets in the act of transferring, so as to prevent a shifting thereof; otherwise difficulty may be encountered in causing the eyes to engage the pin. To this end is provided the t ansfer device shown in Fig. 6, consisting of a small disk or head, h, having two guidepins, i, depending therefrom for engaging corresponding peripheral grooves, j, formed longitudinally in the sides of the holding-pin D, the said device being designed to be passed through the eyes of the index-sheets while engaged by the holding-pin and to be stripped from said pin simultaneously with the indexsheets, thereby retaining said sheets in the same position with all the eyes in exact alignment, thus facilitating the engagement of said eyes with the pin on the permanent file.

It is obvious that the two pins being set apart a distance equal to the diameter of the holding-pin, the eyes which fit the latter must be held in exact alignment by said pins when withdrawn from said holder; and it is immaterial, so far as concerns this portion of my invention, whether the holding-pin be iiXed or yielding.

In a device constructed as just described there is embodied the three essential elements of a device of this character namely,

simplicity, durability, and econ omy-in addif tion to which the actuating mechanisms are concealed from view, and at the same time protected from injury or unnecessary wear 0ccasioned by the'lodgment therein of dust or other foreign substances.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The binder-frame, in combination with a holding-pin normally perpendicular to the bottom of said frame, and a pivot-connection between said frame and pin, whereby said pin may be deflected laterally to receive the index-sheets, substantially as and for the purpose described.

2. The binder-frame, in combination with a holding-pin normally perpendicular to thc bottom of said frame, a pivot-connection between said frame and pin, and a catch device on the arm of said frame for engaging the free end of said pin and locking the pin in its upright position, substantially as described.

3. The binder-frame, a holding-pin perpendicular to the bottom of said frame, and a pivot-connection between said frame and pin, in combination with a spring actuating the pin resisting a lateral deflection thereof, whereby said pin will be automatically returned to its normal position when released, substantially as described.

4. The binder-frame, a holding-pin normally perpendicular to the bottom of said frame, and a pivot-connection between said frame and pin, in combination with a spring engaging said pin, so as to resist a lateral deflection thereof, and a spring-catch secured to the rim of said frame and arranged to be automatically engaged by said pin, substantially as described.

5. In a temporary binder, the holding-pin providedwith longitudinalperipheralgrooves, in combination with a disk or head and pins secured to said head for engaging said grooves, substantially as described.

G. In a temporary binder, the index-holder, in combination with theindeX-frame, a pivotconnection between said frame and holder, and a stop device for preventing a reversal of the operative face 0f the index-frame with reference to the index-sheets, but permitting a vibration of said frame upon its pivots, substantially as described.

7. In a temporary binder, the index-holder consisting of a lat metallic bail provided with perforations therein, in combination with the index-frame and offset, portions of said frame passing through and working in said perforations and constituting a stop devicefor said index-frame, substantially as described.
