BOOKBINDER.

Application filed December 8, 1923. Serial No. 679,368.

To all whom it may concern:

Be it known that I, FRANCIS L. FISHER, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Bookbinder, of which the following is a specification, in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a book binder intended to provide a binding for loose leaf books which is capable of being subsequent- 1y made into a permanently bound book when the desired number of leaves has been assembled therein.

It will be understood by those skilled in the art that during the course of a month or several months, there may be an accumulation in a loose leaf book of a series of invoices or bills or ledger leaves,whicrh leaves are removed from time to time for changing or for having certain matter added thereto, but which leaves, after a certain period book in a permanent form. This book is intended to provide for both contingencies, that is, it is used in the first instance, for the binding of the loose-leaf-incompleted book. When the desired number of leaves has been placed in position, the covers and leaves are made into a permanent book from which the leaves cannot be easily removed unless they-are torn out, the binding posts being then bent down as shown in dotted lines inFig. 1.

Another object of the invention is to provide abinding'postfor the book which will be stiff enough to hold its proper position in the simplest possible manner.

Another object of the invention is to produce a binding post which will be very stiff in one plane, but very easily bent. over in a plane at right angles thereto when it is desired to produce a permanent book.

Another object of the invention is to provide the book binding with means for concealing the bent over ends of the post there by producing a neat binding with no rough edges projecting. i

A further object of the invention is to provide a lock for securing the binding in the locked position, said lock being capable of being made stiff'enough to be substanof time, are bound up in the tially permanent when once inserted in place, 1f that is desired.

Other objects of the invention will appear I r same portion throughout, but I am aware that there may be modifications thereof.

Fig. 1 is a perspective View of the completely bound permanent book,

Fig. 2 is an end view of the lower cover of the book,

Fig. 3 is an edge elevation of the lower cover of the book lookingat right angles to Fig. 2,

Fig. 4 is anedge elevation of the lower cover and the upper cover of the book, no leaves being shown in place, a portion of the cover and back being shown in section for purpose of illustration, this figure illustrating the way the book temporarily appears during the time the leaves may be inserted therein or removed therefrom.

Fig. .5 is an edge view of the back end of the upper cover of the book showing the binding post ready to be turned down,

Fig. 6 is an edge view of a portion of the upper cover of the book showing the bind- ,ing post turned down and the cover in the proper position for protecting the book leaves,

Fig. 7 is a plan view of a portion of the back of the book binding showing the manner of securing the binding post thereto,

Fig. 8 is a plan View of a portion of the upper cover of the book showing the binding post turned down preparatory to looking the back edges of the upper cover to gether, V V

Fig. 9 is a side elevation, and

Fig. 10 is a plan view of the locking member for securing the two back edges of the cover together. i

Fig. .11 is a perspective view of the looking device which may be applied to the loose cover to preventit from dropping off the binding posts.

The two covers consist of the ordinary pair of metal strips 3, 1 and 5 with edges inturned to form slotted-tubular members by suitable cloth strips 6 and 7, or by leather hinge material, if desired, which completely covers said metal elements and which is glued to the edges of binders board covers 1 and 2. r

The metal strips are all made substantially alike and consist of a flat piece of metal 8 with the inturned edges 9 spaced from each other and spaced from the middle of the strip far enough to leave room to insertaprong of. the sheet-metal lock 10.

This lock has a short prong-11 and a long prong 12 to facilitate its insertion into the two strips 4; and 5 of the upper cover. The prongs of the lock 14' have crimped portionsas indicated at 13 which may be arrangedtofit so tightly into the end of the metal strip as to substantially prevent'its removal, or it may be flat as to allow it to be removed at will.

The lock has a knob 1a, which may be made of a suitable material to prevent it from injuring desks or furniture, the metal strips being short enough to allow said knobfto come in alignment with each edge of the cover 2, as illustrated at 16, Fig. 1.

It will be seen that the upper cover has two of the metal strips 1 and 5 connected thereto and that they are hinged together at. 17 and are hinged to the cover at 18, the construction of said metal strips being such that when the cloth cover is put on there will'be a groove in eachstrip as shown at 19 and 20, in Fig. 8, the object being to allow the posts 21 and 22 to be locked in place, as shown in Fig. 8, by being hammered down into the groove produced in said metal strips and not increase the thick ness of the same.

The posts21, 22 consist of doubled lengths of. wire the ends of which, as shown at 23,. 24, are bent at right angles to the two wires insuch a manner as to stand'substantially parallel to each other, but adapted to be inserted at an angleof forty-live degrees to the length of the metal. strip to which they are secured the object being to hold saidposts as stitfly as may be.

In use a series of loose-leaves, such as bills or invoices are assembled in the book, when it is in the condition illustrated in Fig. 4,,and as longasit is desired to add leaves toor remove leaves from the book, the posts 21, 22 are allowed to remain in that, condition- However,- when all of the leaves have. been assembled in the book, that itis desired to place there, the top cover is then turned back with the member 5 free from the posts 21, 22. as shown in Fig. 5, whereupon the two posts 21 and 22 are hammered down tightly on the member l'to the position illustrated in Fig.8. The cover ofthe book is then turned over to the position shown in Fig. 6, whereupon one of the locks 10 may be inserted in each end of the two strips 4 and 5 to hold the book permanently in the shape shown in Fig. 1. It will be seen from the above that the posts 21, 22 for holding the leaves pass through holes in both ofthestrips a and 5 when the book is 'usednierely as a loose leaf book, as for example, when leaves are being'put in from day to day, but that when the book is full that the member 5 is removed from the posts and the posts then pass through only the member 1 and the book is changed .to a permanent formby having the posts bent down, whereupon the cover 2 may be closed inthe usual manner.

In Fig. 11 there is shown a formof locking device which is intended to secure a. loose cover in place while the book is being used as a detachable loose leaf book. In this figure the numeral 30 indicates the book cover, 31 the hinged portion of the book cover through which the binding posts pass, 32indicates one of the binding posts, and the locking device consists of a curvedwire 3 1 pivoted to the hingedtmember 31 at 3 1. This allows the locking device torotate in the plane of the binder cover and-its pointed end 38 is adapted to pass between the two wires of the binding post spreading them apart to prevent the cover from slipping off, offthem.

lVhatI claim is as follows, but modifications may be made in carrying out the in vention shown in the drawings andin the above particularly described form thereof, within the purview of the invention, as .defined by the annexed claims.
