9 Claims.
This invention relates to plastic bindings, such as are disclosed in the United States Patent No, 1,970,285 to Douvry, issued August 14, 1934, and in my copending United States patent application, Serial No. 227,242 entitled Plastic binding, and led on August 29, 1938, and has for its principal object to provide a simple machine for opening bindings of this character to allow the pages to be bound to be inserted in the bind- Another object of this invention is to provide a machine for spreading open the rings of plastic bindings and for allowing the rings to curve back into their closed fcrrn one at a time so that, when a binding is being inserted into a group of sheets, the sheets may be manipulated so as to guide the end of each ring into its aperture in the sheets.
Another object of this invention is to provide a means for holding the rings of a plastic binding i".
above which shall be extremely simple in its construction and therefore low in cost and which shall be rugged and reliable in use.
One of the principal features of the present invention is the provision of a mandrel having a tapered end and a parallel sided body portion which is adapted to be forced through the rings of a plastic binding and to expand them to an i open position.
Another feature of the present invention is the provision of means adapted to engage the sides oi' the separate rings of the plastic binding to hold the rings in line while they are being opened so that they will be correctly spaced when the leaves or sheets to be bound are placed upon the rings.
Still another feature of the present invention is the provision of a guide or slide for holding the mandrel in line with the rings of the plastic binding so that it may readily enter them.
Other objects and features of the present invention are set forth with greater particularity in the following description and the accompanying drawings, in which:
Figure l is a front elevation of one of the preierred forms of the invention; Y l
Figure 2 is an end elevation of the machine shown in Figure 1; i
Figure 3 is a plan View, on an enlarged scale of the essential portion of the machine;
Figure 4 is a cross-sectional view taken on the line IV-IV of Figure 3 and looking in the direction of the arrows;
Figure 5 is a cross-sectional View taken on the line V-V of Figure 3 and looking in the direction of the arrows;
Figure 6 is a plan View of a portion of the machine;
Figure 7 is a cross section similar to Figure 4 but showing the mandrel in operative relation to a binding;
The form of the invention illustrated in Figures l to 7 comprises a pair of standards IIJ and li connected together by stringers I2 and I3 and tie rods I4 and I5. The top of the standards le and i l carry a p'air of guide rails I6 and I1 mounted upon spacer blocks I8 and I9.
At one end of the machine, the rear guide rail Il carries a holder 20 for a plastic binding 2| and the iront guide rail i6 carries a device 22 for maintaining the spacing of the rings 23 of the,
binding 2|. The holder 20 comprises a base 24 iiXed to studs 25 vertically slidable in holes in the rear guide rail Il. Setscrews 26 are provided in the guide rail I'I for gripping the studs 25 and holding the binding holder 20 at any desired height above the guide rail. A plurality of hooks 2l' formed of flat strips of metal bent to the shape shown in Figure 4 are mounted on top of the base 2l! with their stern portions 28 extending under and clamped by a cover plate 29. The front edges of the base 24 of the holder and the cover plate 29 are notched out between the hooks 2'! so that .the rings 23 of a binding 2| whose backbone 3l is held by the hooks 2'! can extend in back of the hooks.
The ring spacer 22 is formed of a metal plate having a plurality oi transverse grooves cut into its upper surface and extending out to the edge adjacent the binding holder 20. Both the grooves 32 the ring spacer 22 and the notches 3i! between the hooks 21 of the binding holder 2li are made with the same spacing as the rings or the binding, and the sides oi the grooves 32 are in Vline with the sides of the notches 30, as shown in Figure 6, so that the edges of the rings '23er the binding may bear simultaneously against the sides of the vgrooves 32 and notches 3e without any distortion of the rings. Thiswill hold the rings straight when any lateral force is applied to them. The guide rails i6 and I1 carry a slide 34 movable along the guide rails and prevented from coming off of the rails by a -rails I6 and i1.
and the body of the mandrel 36 is parallel sided and is wide enough to spread open the rings 23 of the binding as shown in Figure '1.
The slide 34 and the mandrel 35 are caused to slide from one end of the machine to the other by a foot pedal 3S journaled upon the lower frame tie rod I5, as shown in Figures 1 and 2. The pedal 38 is connected to a chain 3S which travels over a pulley or sprocket 4E! mounted upon the Stringer i3 and which is connected to a lever 4l. The lever 4! is fulcrumed upon a bracket 42 on the frame and extends up to near the guide rails I6 and l1 where its upper end is connected by a link 43 to a depending stud 44 on the slide 34. A spring 45 acts upon the lever 4| to swing it over to one side and resiliently hold the mandrel 36 withdrawn from the position in which it engages the binding 2 l.
The operation of the machine is as follows:
A binding 2l is placed in the machine as shown in Figure 4 with its backbone 3| inserted into the hooks 21 on the binding holder 2U. The holder 2U is then adjusted vertically for the particular size of binding so that the rings 23 of the binding rest slightly in the grooves 32 of the ring spacer 22. A mandrel or bayonet 36 of the proper width is then secured to the slide 34 by the screws 43, the machine being provided with a plurality of interchangeable bayonets 36 for use with bindings having rings of different sizes.
The operator then depresses the Vpedal 38 which swings the lever 4i to the left, in Figure 1, and moves the slide 34 to the left on the guide The mandrel 36 carried by the slide 34 thereupon enters the rings 23 of the binding 2 l, and the tapered end 31 of the mandrel spreads the rings apart as shown in Figure 7. During this operation, the sides of the grooves 32 in the ring spacer 22 prevent the rings 23 of the binding from being pushed over to the side by the mandrel 36.
The group of pages or leaves 46 to be bound is then taken and placed on edge on top of the mandrel 36 with the holes or apertures l1 in the pages opposite the ends of the individual rings 23 of the binding, as shown in Figure '7. rhe pedal 38 is then allowed to rise slowly, this movement being caused by the spring 45, and each ring 23 of the binding closes upon itself through the holes 41 in the sheets 46 as the mandrel 33 is withdrawn from it.
After the mandrel 35 is withdrawn from the entire binding 2l, the binding, together with the pages 45 which are now secured together. by the binding, may be removed from the machine by merely being slid out of the hooks 21, and the machine is ready to bind another book.
While I have shown only one embodiment of my invention, it will of course be understood that the machine which I have illustrated and described in this specication and the accompanying drawings embodies features which are useful, not only in combination, but also individually. For example, the ring spacer 22 may be used in other forms of machines for opening plastic bindings, such as are shown in U. S. Patent No. 2,108,-
136 issued to Nelson et al. on February 15, 1938, or in my copending application entitled Machine for applying plastic bindings and the like, Serial No. 226,032, iiled on August 22, 1938. The ring spacer 22 may be made with slots cut through its entire thickness instead of with grooves as shown, and it may then be possible to eliminate the vertical adjustment of the binding holder 20. It is also to be understood that the term plastic binding, as used in this specification is not to be limited to bindings made of plastic material but includes any other binding of the same type made of other materials such, as' for example, resilient metal, this term being used in the specication and claims because it is the term by which bindings of this general type are known in the trade. My invention, therefore, is not to be limited to the exact structure which I have shown but includes lanything' falling within the terms of the accompanying claims, these terms being, of course, given the broadest meaning which they will reasonabli7 support.
