Application filed August 16,1900 Serial No. 27,024. (No model.)

To @ZZ whom t may concern:

Be it known that I, FRANCIS WAYLAND BRIGGS, a citizen of the United States, residing at Lewiston, in the county of Androscoggin, State of Maine, have invented certain new and useful Improvements in Ledger- Holders; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to binders especially adapted to the loose-leaf system of bookkeeping; and one object is to provide a loose-leaf binder which is simple in construction, certain and reliable in operation, and which may be manufactured at a moderate cost.

A further object is to provide a binder which when in its unlocked position preparatory to removing or inserting a leaf will always retain the loose leaves in their proper position.

A further object is to provide a binder which when separated for the purpose of removing or inserting a leaf the leaves of each part of the separated book will be retained in their proper position, thus preventing their accidental confusion and loss.

To these ends the invention consists in a binder for loose leaves constructed substantially as hereinafter illustrated and described, and defined in the appended claims. Referring to the drawings, in which similar letters of reference indicate similar parts, Figure l is a view in perspective of a binder constructed in accordance with this invention, the parts being in the position assumed when unlocked and preparatory to separating the leaves of the book. Fig. 2 is a similar View, the parts being in their locked position.4 Fig. 3 is a view in elevation of the binder separated from the covers and in the position shown in Fig. 1, parts being in section. Fig. 4 is a vertical transverse section through the middle portion of the binder shown by Fig. 3. Fig. 5 is a partial horizontal section on the line 5 5 of Fig. l3.

In the drawings, A represents a volume of any desired dimensions containing loose or separated and removable leaves a, which may be adapted for any particular purpose, as a ledger, duc., and having suitable covers A' and A, between which the loose leaves are held. The rear edge of each cover is reinforced by a` metal strip a' a2', which strips are secured to the covers in any suitable manner. In each of the strips a' and a2 are secured one or more pins ai and on, which are adapted to engage openings or perforations a5 and a6, formed, respectively, in the strips a' and a2, as clearly shown in Fig. 3. These pins may be secured to the binder-strips in any suitable way; but I prefer to pass each pin through a suitable opening. in one strip and to rivet or head the'pin against the strip, thereby firmly securing the parts together.

By reference to Fig. 3 of the drawings it will be noted that a series of two pins a* are The strip 0.2 is provided on opposite sides of the group of pins a4 with apertures a6, that o'n the strips d2, whereby the two strips may V be pressed toward each other for the pins of one strip to enter the openings of the other strip. It will thus be observed that each of the two strips is provided with a group of pins adapted to have engagement with the leaves of the book, which are likewise engaged with the pins of the other strip, and this engagement by the pins of the strips with the leaves aords a` means by which the leaves can be separated at the middle or end portions of the book, whereby this engagement of the strips a' a2 and their pins with the leaves permits the leaves to be taken apart in a way to permit each group to remain in engagement with certain pins when it is desired to separate the book at a particular point for the insertion or removal of one or more pagesthat is to say, a book containing, say, three hundred pages may be opened at, say, page 100. The rst one hundred pages may remain in engagement with IOO the pins @Sand the strip a' on the removal of the latter `from the book, while the remaining two hundred pages of the book will remainin engagement with thepins a4, attached n to the strip a2, whereby all the leaves will be an extension b, which is 'doubled under thei strip a2 and firmly riveted thereto, forming a strengthening for the corners of the cova ers, as clearly shown in Fig. 3. In a similar manner the other strip d' is provided with the locking-'bars B', which are folded around the ends'ff the strips d' and are attached tofby riveting or othersuitable means, so as to acrd reinforcements to said strip a'. v'lhedepending portions of these locking-bars B' areprovided with suitable perforations b5 and are adapted to fit slidably in the socketsl B on the strip a2, which is a companion 13,0 11h@ Strip ft', whereby the adjustment of th `l lcking-bars B' in the sockets B provides fplv I'rati'on in 'the width of the space between the companion strips a' a2.

haveprovided means for detachably lock- 3o ing-the bars B' at dierent points with reto the socket-pieces B, so that the comp'rauion strips a' d? may be separated or adju ted laterally at suitable intervals to accqniinodate an increased number of pages in thebook.` The ysockets B are provided at their enter sides with the latch-plates b', that Vdisposed ,coml pactly against the sockets, 'so as to be entirely out of the way.V Each latch-plate b' is attached at its lower end to "socket B by a rivet 0r screw,y as indicated clearlyat the left hand of Fig 3,; but th p Yte' is provided at a point intermediate Q ts'length with a latch-'stud b3, which passes gh transverse opening 0f the socket- B and is adapted to `it in either of the which is slidably fitted in the proper socketpiecle. By reason of the compact location of the latch-piece against the socketpiece I have found thatthe desired elasticity or spring cannot be given to the latch-plate. Hence I r, tte the employment of a leaf-spring be,

series of `apertures' in the locking-bar '13',

socket-piece B adjacent to the free end of each latch-plate, and this stop is provided with Aarhead that lies in the path of said free end of the latch-plate for the purpose of limiting the movement thereof in a direction to withdraw the stud b3 :from the perforated locking-bar B", wherebyA the latchplate is restrained against undue movement Awhich would tend to disengage the stud b3 from the transverse opening of the socket-piece B.

Upon the under side of the strip a' is secured Va spring-plate D by means of rivets passing through its central portion and the strip, as clearly shown in Fig. 3.

The ends of the spring-plate D extend to a point near the socketrpieces B and are bent downwardly, bearing upon the ends o f a guide-'bar D', which is provided with suitable perforations d, through which the pins CL3 and a4 are guided when the parts are being pressed together and locked.

It will be seen from the construction above described that by simply withdrawing the lugs b3 the strip d' will be forced up ed of the leaves a by the action of the spring-plate D. The hand may now be readily inserted between the leaves atv the desired point and the strips separated. The desired additions or alterations' can now be made and the parts again returned to their former position. It is of course understood that the leaves or pages d are provided with suitable perfora# tions for theV passage of the pins a3 and d4.

By reference to Fig. 3 of the drawings it will be noted that the guide-'bar D' is slidably fitted on the pins of the two series, Which are attached, respectively, to the companion strips d" a2; but this guide-bar is pressed normallyin one direction by the spring D, the end portions of which are slotted so ,asto play loosely on the pins 61,3 ofthe strip d'.'
