GEORGE F. WATT, OF CHICAGO, ILLINOIS.
BINDER FOR LOOSE-LEAF BOOKS- SPECIFICATION forming part of Letters Patent No. 750,922, dated February 2, 1904.
I Application filed February 3, 1902. Serial No. 92,271. (No model.)
To all whom it may concern:
Be it known that I, GEORGE F. WVA'r'r, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Binders for Loose-Leaf Books, of which the following is a specification.
This invention relates to the construction of binders for loose-leaf lodgers and other similar books.
The main features of the invention concern the posts upon which the leaves are threaded and the manner of giving movement to the posts in expanding and contracting the book and to the manner of locking the actuating device by which the posts are operated.
The nature of my improvements, as well as their mode of operation, will be fully understood from the accompanying drawings, in which Figure 1 shows an inside view of my improved binder, partly in section. Figs. 2 and 3 are sections upon the lines 2 2 and 3 3, respectively, of Fig. 1. Fig. 4 is a section similar to Fig. 3, showing the book contracted. Fig. 5 is a view similar to Fig. 1 of a modified construction. Figs. 6 and 7 are sections on the lines 6 6 and 7 7, respectively, of Fig. 5. Fig. 8 is a detail section showing one of the sheets in conjunction with the retaining-posts.
My invention, as shown in the drawings, is applied to what is known as a three-piece-back binderthat is to say, it embodies the clamping- bars 10 and 11, to which the covers (not shown) are hinged, each being provided with an overhanging flange 12, forming part of the back of the book, and a plate 13, covering the open space between the flanges 12 and lapping over said flanges, so as to complete the back. This plate 13 forms a support for the devices by which the clamping-bars are opened and closed, and at its ends it is bent at right angles and then doubled upon itself, as plainly shown at 14 in Fig. 6, so as to inclose the end flanges 15 on the clamping-bars. The flanges 12 and 15 are preferably formed of sheet metal.
The posts upon which the paper is threaded are four in number, and each is composed of a male and a female section adapted to telescope and permit the clamping-bars to apposts are also both attached to the same bar as, for instance, to bar 11-and the male sections 19 of the same posts are both attached to the opposing bar, which in the construction shown is bar 10. With this number of posts and this construction all the leaves will be uniformly positioned, becasue all will be bearing against either the female sections 16 or 18, and both pairs of those sections are adapted to hold the leaves upon them in identical positions.
The two companion posts at the top of the book are arranged close together, as shown, so that both may enter the same notch or recess 40 in the leaves &1, and the same is true of the two companion posts at the bottom of the book, as will be understood from Fig. 8. The openings in the leaves are oblong or oval and larger than those customarily employed; but I deem this an advantage rather than a detriment, as the paper has a more extended bearing in front and rear of the posts and will be more firmly held thereby.
The female post-sections 16 and 18 are all provided with racks 20 upon their proximate sides, and between each pair of them is located a pinion 21, meshing with the racks of both sections and mounted upon shafts 22, secured to the back 13 by screws 23 in such a way as to permit the shafts to revolve. When the pinions turn, it will be noticed that the postsections 16 and 18 will move in opposite directions, so as to cause the clampin -bars to move toward or away from each other and the posts to lengthen or contract, according to the direction of the rotation of the pinions. The pinions 21 are caused to move in unison by racks 24L and 25 upon a sliding bar 26, meshing with pinions 42 on the shafts 22, and they may be operated either by power applied to the rack-bar or by power applied directly to the clamping-bars. Fig. 1 shows the device adapted to be operated in the latter way,
while the modification shown in Figs. 5, 6,
and 7 shows means for imparting the sliding movement to the rack-bar, and thus causing the expanding or contracting of the bars. Where the device is constructed as in Fig. 1, the rack-bar simply serves as a means of regulating and securing uniformity in the movement of the pinions, so that the book will be expanded and contracted to the same extent at top and bottom.
In order to hold the clamping-bars rigidly in any of their adjusted positions, I provide means for locking the rack-bar against movement. Any suitable means may be used for that purpose; but I have illustrated a pivoted dog 27, engaging teeth 28 on the rack-bar, a screw 29, operable through an opening 30 in the bottom end of plate 13, and a connecting-link 31, extending from the screw to the dog. This link has its end bent at right angles and threaded on the screw, so that by turning the screw thelink may be forced up- ,ward, and thereby cause the dog to release its hold on the rack-bar. /Vhen the link is turned down, it causes the locking of the rack-bar. The rack bars movements are guided by guides 32 and 33, and these guides preferably overlap the rack bar, so as to confine it against the plate 13. A stop 34 may be employed to limit the motion of the rack-bar in the expanding direction. The parts are shown in Fig. 1 as being fully expanded.
In the modified construction shown in Figs. 5, 6, and 7 I have not shown any means solely for locking the rack-bar, but instead thereof I actuate the rack-bar by means adapted to hold it against movement when at rest and consisting of a screw 35, accessible through the opening 30 in the bottom end of the plate 13. This screw is provided with shoulders 36 36 at opposite sides of a clip 37, through which it passes and is prevented from moving longitudinally. It passes through a projection 38 on the rack bar, as plainly shown, and is adapted to impart longitudinal movement to the rack-bar and through the rack-bar to actuate the postpinions 21. Except as described, the modified construction is like that illustrated in Figs. 1 to 1. This construction locks the rack-bar against longitudinal movement when such movement is not desired or is not produced by operating the screw 35 as effectually as does the locking-pawl of the other construction; but of course I do not wish to be understood as saying that no looking means can be employed with the construction of Figs. 5 to 7, as obviously means similar to those shown in the other figures might be used, if desired.
