BINDER-FRAME.

Specification of Letters Patent.

Patented Au 23, 1910.

Application filed. May 19, 1910. Serial No. 562,189.

To all whom it may concern:

Be it known that I, LAURENS P. DIXON, a citizen of the United States, and a resident of New York city, borough of Manhattan, in the county of New York and State of New York, have made and invented certain new and useful Improvements in Binder- Frames, of which the following is a specification.

My invention relates to an improvement in binder frames for use in connection with loose leaf ledgers, the object of the same being to provide a binder frame which shall be simple and economical to construct, durable, strong, and eflicient in use, neat and pleasing in appearance, and having its parts so constructed and assembled as will permit of the retention of a large number of leaves between the binding elements, and which leaves may be easily and readily inserted therein or removed therefrom.

A further object of the invention is to improve upon the construction of the frame shown and described in the Letters Patent granted to Anderson & Prigge, assignees of Frank Greiner, dated March 24:, 1908, and numbered 882,880, which improvements I have designed as a result of the manufacture of a large number of frames like that disclosed in said patent, and with these and other ends in view, the invention consists in certain novel features of construction and combinations of parts as will be hereinafter fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a binder frame constructed in accordance with my invention, the parts being in their open or separated positions to permit of the insertion of the leaves. Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1. Fig. 3 is a cross-sectional view taken on the line 3 3 of 1. Fig. at is a similar view showing the frame in its closed position.

Referring to the drawings, 5 represents the back, and 66 the binding plates or sections, the latter being curved or rounded in a cross section and provided with the ends 77 adapted to fit within the upwardly turned ends 8 of the back 5, these binding plates 66 adapted to travel transversely with relation to said back as hereinafter described. The side plates 6-6 are provided with the flanges 99 between which the leaves of the ledger are held and bound, said platesv being also provided with the telescopic tubes 1010, the foregoing elements being constructed and arranged as in the case of the binder shown and described in the patent above mentioned.

On the inner side of the back 5 are cast or otherwise formed integral therewith the lugs or projections 1l11 extending upwardly between the ribs or flanges 1212, the latter extending lengthwise of the back from end to end and tending to strengthen and stiffen the same and joining the plates l3l3 formed integrally with the upwardly turned ends 8 of the back 5, and on which plates 1313 slide the ends of the binder plates 6.6.

On the lugs or projections 11'11 are secured by means of the screws lllt the blocks 1515, held stationary with relation to the back 5 and plates 6, and as hereinafter explained, are adapted to guide the latter in their transverse movements. Within these blocks 1515 are secured the extreme ends of the guide rods 16l6, which assist in stiffening and strengthening the back. In the lugs 1lll is journaled the rod 17, the opposite ends of which are provided with right and left threads 18 19, the extreme upper end 20 of the rod extending within a Short distance of the upwardly turned end 8, and squared to receive a key for turning the same, and access to which is had through the opening 21 in said upwardly turned end 8. This rod 17 is held in place within the lugs 11 by means of the blocks 1515, but which permitof the free rotation of the same. On the threaded portions 1819 of the rod 17 are fitted the traveling nuts 2223, said rod passing through tapped openings in the same, and through which nuts 22 23 also pass the rods 16 in order to guide said nuts in their longitudinal movements. It will be understood that when the rod 17 is turned in one direction, the nuts 23 tapped thereon, will travel toward each other, and when the rod 17 is turned in the opposite direction, said nuts will be caused to travel in the opposite direction, that is, in a direction away from each other and toward the outer ends of said rod.

To the traveling nuts 2223 are pivoted the inner ends of the levers 24, the outer ends of the latter being pivoted to the plates 6, the result being that as the nuts are caused to travel toward each other, said plates 6 will be caused to travel inwardly toward each other, and when the nuts are caused to travel in the opposite direction, the binding frames will also be caused to separate. To assist in guiding these plates 6 in their transverse movements, I secure to the lugs' formed integrally with the plates 6, the outer end of the rods 26, the inner ends passing into and through openings formed in the blocks 15, the lugs 25 being provided with the recesses or openings 27 in order-that the free inner ends of said rods 26 may enter the same when the plates 6 are brought together as illustrated in Fig. 4. By means of this construction, it will be understood that the transverse guide rods 26 pass entirely through the blocks 15, the latter forming a long and substantial bearing for the rods and resulting in a strong and stiff structure, the plates 3 being permitted to freely travel transversely of the back 5, yet at the same time preventing it from twisting or binding during their transverse movements.

A binder frame constructed as above described contains many improvements over that described in the before mentioned patcut; it is far neater in appearance, as the rods 16 extend but part way the length of the back instead of from end to end. The blocks 15 provide a long or wide substantial bearing for the transverse guide rods and at the same time afford a substantial anchorage for the ends of the longitudinal guide rods 16, and finally the binder is much more economical to construct and assemble.

lVhat I claim is:

1. A binder frame comprising a back provided with lugs, a rod formed with right and left threads and journaled in said lugs, blocks secured to said lugs, binder plates moving transversely on said back-plate and provided with transverse guide rods moving in said blocks, nuts traveling 011 said threaded rod, and means connecting said nuts with said binder plates, substantially as described.

2. A binder frame comprisingaback-plate provided with lugs, a rod provided with right and left threads journaled in said lugs, blocks secured to said lugs, longitudinal guide rods having their ends anchored in said blocks, binder plates mounted on said back-plate and provided with transverse guide rods sliding in said blocks, nuts traveling on said threaded rod, and means connecting said nuts with said binding plates for moving the latter transversely with relation to said back-plate, substantially as described.

3. A. binder frame comprising aback-plate provided with upwardly turned ends and plates 1313 formed integrally therewith, said back-plate being also provided with ribs or flanges extending lengthwise of said backplate and connecting said plates 1318, lugs formed on said back-plate between said ribs, a rod provided with right and left threads journaled in said lugs, blocks secured to said lugs for retaining said threaded rod in place, binder plates provided with transverse guide rods moving in said blocks, nuts traveling on said threaded rod, means for connecting said nuts with said binder plates, and longitudinal guide rods passing through said. nuts and having their ends anchored in said blocks, substantially as described.

Signed at New York, borough of Manhattan, in the county of New York and State of llew York, this 18 day of May, A. D. 1910.
