CHARLES C. MALTBY, OF CINCINNATI, OHIO, ASSIG-NOR TO THE TWINLOCK COMPANY, OF. CINCINNATI, OHIO, A CORPORATION OF OHIO.

LOOSE-LEAF BINDER.

To all whom it may concern:

Be it known that I, CHARLES C. MALTBY, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification.

This invention relates to certain improvements in loose-leaf binders and has for its objectto provide a device of this general character of a simple and inexpensive nature and of a compact, strong and durable structure which shall be adapted for securely holding the leaves or sheets while being capable of convenient and ready operation to detach such leaves or sheets to permit their removal substitution or replacement and being also capable of a wide degree of adjustability to accommodate the improved binder for holding a greater or lesser number or thickness of the loose leaves or sheets.

The invention consists in certain novel features of the construction, combination and arrangement of the several parts of the improved loose-leaf binder whereby certain important advantages are attained and the device is rendered simpler, cheaper and stronger and is otherwise better adapted and made more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings which serve to illustrate my inventionFigure l is a perspective View showing a binder constructed according to my invention. (This view is drawn upon a small scale.) Fig. 2 is a fragmentary view showing the interior of the back of the improved binder, its sides or covers being thrown flat or open and partially broken away for lack of space. This view is upon a larger scale and illustrates those portions of the mechanism of the binder which are visible when the device is opened in the way shown. Fig. 3 is a trans verse section taken through the back and sides or covers of the binder in the plane indicated by line aa in Fig. 2. Fig. at is a partial section taken longitudinally through one end portion of the back of the binder and showing certain features of the adjusting and locking means carried thereby. Fig. 5 is a detached detail view showing one of the metal hinge-strips employed in the con- Specification of Letters Patent. Patented Sept. 21, 1909.

the back of the binder detached, and Fig.

8 is an edge view of the same with one end portion in central section. Fig. 9 is an enlarged partial inside view of the back part of the improved binder at one end thereof and illustrating the construction and arrangement of the adjusting means for holding the sides or covers in relation, certain portions of the device being broken out and shown in section for purposes of illustration. Fig. 10 is a'fragmentary end elevation, also partly in section and illustrating the parts shown in Fig. 9.

As seen in these views, the back of the binder is made in sectional form and comprises a central body portion 1 herein shown as produced from a metal plate 2 covered over with leather or other suitable material and bent or curved in transverse cross-section so that its rear surface shall present the convexity commonly present in the backs of bound volumes. The back of the improved binder also comprises lateral members formed from metal plates adjustably held upon opposite edges of the main or body portion 1 and extended longitudinally along the same and provided with hinging-strips with which the sides or covers of the binder have hinge connection as will be hereinafter explained. The metal plates of which said lateral members of the back of the binder are formed are centrally bent to produce portions at right-angles so that each lateral member has an angular or L-shape in cross-section, and one of the angular wings of each of said lateral members is extended upon the inner surface of the main or body portion 1 of the binder-back as shown at 3 on the drawings and has means for guiding it and adjusting it upon said main or body portion, while the other angular wing or portion 4 of each of said lateral members is extended forwardly from the plane of said main or body portion and is provided with means for detachably holding the loose leaves or sheets of the binder and also for connection of the sides or covers of the binder thereto.

At opposite ends of the binder-back, the lateral members thereof are provided with telescoping members of rectangular crosssection forming guides or gages for position- Cir ing the loose leaves or sheets held between the sides or covers, one of the telescoping parts as shown at 6 being carried upon one of the lateral members of the back and playing endwise within the other part which, as

shown at 7 is carried upon the other lateral member of the back, and the rear walls of said telescoping members or parts 6 and 7 at the opposite ends of the binder-back are provided with longitudinally-extended slots or channels 8 which, when the parts are assembled, are caused to extend transversely of the binder-back and are adapted to receive guide pins or studs 9 carried upon guide- plates 10, 10, at opposite ends of the main or body portion of the back. The pins or projecting studs 9 are headed at their forward ends to prevent them from being disengaged from the slots or channels 8 of the parts 6 and 7.

At the opposite ends of the main or body portion 1 of the binder-back are erected bracket-supports 2 upon the forward surface of said body portion and these brackets 2 have supporting surfaces 12 extended along their outer edge portions on which the outer ends of the guide-plates 10 are rested flush, screws 11 being provided for the secure attachment of said guide-plates to said bracket-supports, as shown in Figs. 2 and 9. Adjacent to the supporti11gsurfaces 12 of the brackets 2 the forward sides of said brackets are provided with side bearings 1%, extended transversely of the binder-back and separated from said surfaces 12 by offsets or shoulders 13. The plane in which each bearing-surface 14 is extended is at the rear of the plane in which the adjacent surface 12 is produced so that in this way there are produced in the rear of the respective guideplates 10, 10, slide-bearings between the same and said bearing-surfaces lt and in these slide-bearings are adapted to be received the end edge portions 15 of the rear angular wings or portions 3, 3 of the lateral members of the binder-back, which edge portions 15 abut on the offsets or shoulders 13 and are thereby guided for lateral movement toward curely in position upon said body portion of the back. The opposite sides of the plates 16 are also provided with rearwardly .directed lugs or projections 20, 20 engaged outside the lugs 19, 19 on the body portion 1 for preventing damage of the screw-connections in case of rough handling of the binder. The arran ement of said ltws or projections 19 and 20 is clearly shown in Fig. 3 and in dotted lines in Fig. 10. The bearing-plates 16 are also provided, upon their front surfaces, with perforated lugs 22 in which screws 21, passed through the guide-plates 10, have screw-engagement for the secure attachment of each plate 16 to the inner edge portion of the adjacent guideplate 10. The edges of the wings 3, 3 of the lateral members of the binder-back are cut or notched out as seen at 23 to receive the lug 22.

Upon the bearing-plates 16 are produced shaftbearings 2d alined with each other and located at the opposite ends of the binderback and in said bearings is held to turn a shaft 25 extended longitudinally of the binder-back in the space between the main portion and the wings 3, 3, of the lateral members of said back. One end of, said shaft 25 is provided with a square 23 to receive a key (as shown in dotted lines in Fig. at) whereby the shaft may be turned in reverse directions for adjusting the lateral members toward and from each other and, adjacent to its opposite ends, the shaft 25 is provided with reverse screw- threads 26, 26, which have engagement with nuts 27 located at opposite ends of the binder-back and adapted, when the shaft is turned, to be adjusted lengthwise of said back, toward and from each other being provided with oppositely-directed wings 28, 28, which are adapted, by engagement with the part 2 of the back to prevent turning or twisting movement of said nuts when the shaft is turned. To the opposite wings or extensions 28, 28, of each nut 27 are pivotally adapted the inner ends of links 30, 30, the outer ends of which have pivotal-connection as'shown at 31 with the outer ends of other links 32, the inner ends of which are pivotally-connected with the adjacent bearing-plate 16 as clearly shown in Figs. 6 and 9. At the point-s'of pivotal-connection 31, of the oppositely arranged links 30 and 32 at each end of the binder-back are pivotally connected the inner 7 ends of other auxiliary links 33, the outer ends of which have pivotal-connection as shown at 3 1 with the adjacent portions of the flanges or wings 3 of the respective lateral members of the binderback. By this arrangement, it will be uns derstood that when the key is applied to the squared end 28 of shaft 25 and manipulated to turn said shaft in one direction, whereby the nuts 27 are moved toward each other from the position shown in Fig. 6, the links 30 and 32 at the opposite sides of each end I portion of the shaft will be moved from the angular position shown insaid figure to a position in which they are more nearly alined with the shaft whereby draft will be exerted upon the auxiliary links 33 and,

through said auxiliary links, movement will be imparted to the lateral members of the binder-back to cause them to be approached toward one another. W hen the shaft 25 is reversely turned by reverse manipulation of the key. it is evident that a reverse movement of the parts is effected. he engagement of the end edge portions 15 of the flanges or wings 3, 3, of the lateral members inthe guide-ways intervening the plates 10 and bearings ll serves to effectively guide the late :11 members in their movement so that uniform movement is imparted to the opposite ends of the members. The engagement of the headed pins or studs 9 with the slots 8 of the telescoping parts 6 and T at opposite ends of the lateral members also serves to guide said members in their movement toward and from each other.

Upon the forwardly-extended wings or portions 4, r, of the lateral members of the binder-back are carried the sheet-holding devices which as shown in F 2, 3, 4 and 9 areproduced from lengths or sections and 36 of metal tubing, the sections being carried on one lateral member and being arranged to slide telescopically within the bores of the sections 36 which are carried on the other lateral member of the binderback. The leaves or sheets as seen in Fig. r in dotted lines have rounded openings [0 in which the telescoping sections 35 and 36 are engaged and at the ends of the bindingedges of said leaves or sheets 00 are produced angular cut out or notched portions w which fit against the inner and front faces of the parts or members 6 and T. For the attachment of the sections 35 and 36 to the respective lateral members of the binderback, the means shown in Fig. 9 is preferably employed, said means comprising lugs 37 having heads bearing on the outer faces of the flanges or wings of said lateral members and provided with reduced portions which are passed through perforations in said wings or flanges t and are engaged in the bores of the sections and 36, being traversed by pins or rivets 38, the ends of which are passed through the walls of sections 35 and 36 whereby secure attachment of said sections to the flanges or wings r is effected.

39 indicates hingestrips which are extended lengthwise upon the outer surface of the flanges t of the lateral members of the binder-back, being pressed or otherwise formed up from sheet-metal or the like with transverse braces or reinforces as at their end port-ions and also at suitable intermediate points, the reinforces l0 at the extremities of these hinge-strips being provided with threaded openings all for the reception of screws 42 by means of which the hinge-strips are attached to the ends of the flanges l. The screws 42 are also passed through flanges on the ends of casings or parts 6 and 7 for the attachment of said parts or casings to the flanges l of the lateral members as clearly shown in Fig. 9. The hinge-strips 39 are also provided with central screw sockets or lugs l?) in which are engaged short screws 44 passed through the central portions of the respective flanges at for further attachment of the hingestrips thereto. The screws 4 are indicated in dotted lines in Fig. 2. The hinge-strips 39 are covered over with leather or other material as herein shown although, of course, this is in no way essential to the present invention, and the metal from which said strips are produced have openings punched or otherwise formed in them as indicated at 45, the portions of metal removed in the production of said openings being pressed outwardly as shown at e6 to produce hingelugs which are perforated for the passage of pins or wires 47 which form pintles whereon the sides or covers are adapted for pivotal-movement in opening and closing of the binder. The hinge-lugs d6 are suit ably spaced apart as shown in Fig. 2 and in the hinged edge portion of each cover or side 50 of the improved binder is embedded a steel or other metal plate 49, the edge portion of which is bent to produce eyes 48 engaged on the wire or pin 4C7 between the hinge-lugs 46 for the secure attachmentof the sides or covers 50 to the hinge-strips 39. The leather or other binding-material of the sides or covers 50 is, of course, extended over the plates 4L9 and around the eyes 48 so as to cover and obscure the hingeconnection without interference with a full extent of movement of said sides or covers upon their hinged-connection.

From the above description it will be evident that the improved device is of an extremely simple and lHGXJQIlSlVB nature and of a very compact, strong and durable construction and by reason of its ready adj ustability is especially well adapted for use particularly in ledger-s and similar loose-leaf books, the arrangement of the screw shaft and the linkconnections of its nuts with the lateral members of the binder-back serving for convenient removal of the leaves or sheets when desired. It will also be obvious from the above description of my invention that the improved binder is capable of considerable modification without material departure from the principles and spirit of the invention and for this reason I do not wish to be understood as limiting myself to the precise form and arrai'igement of the several parts of the device as herein set forth in carrying out my invention in practice.
