DEVICE FOR BINDING PAPER SHEETS.
Application filed October 15, 1927, Serial No. 226,492, and in Germany .Tune 25, 1925.
This invention relates to a device for binding together superposed sheets of paper by passing them between two inter-engaging members, preferably two interengaging wheels having tooth-like projections and correspondingly shaped tooth spaces thereon, both members being pressed together and acting with that pressure upon the superposed sheets to cause them to stick together 7 along a line.
It has now been ascertained that the capacity of such a device may be increased considerably if the toothlike' pro ections upon the wheels are provided with flat slopes or bevels extending from the crown or crest of the tooth towards both sides. According to another embodiment of the invention the flat slopes adjacent to the crown of the tooth are continued by steeper slopes adjacent to the sides of the wheel.
In the drawing afiixed hereto and forming part of the specification F lgure 1 is a binding machine with toothed wheels according to the invention in side-elevation, .c
Figure 2, the same in front-elevation, Figure 3, illustrates a binding wheel according to the invention on an enlarged scale, in side-elevation, Figure 4, a further design of such a wheel likewise in side-elevation,
Figure 5, shows a further design of a,
I binding wheel in side-elevation on an enlarged scale,
Figure 6, the front elevation of the wheel in Figure 5, and 4 a Figure 7 a cross-section through thls binding wheel along the line 7-7.
Referring to Figures 1 and 2 of the draw-,
ing 10 is the frame or standard of the machine in which are journaled the binding wheels 11 and 12 and which may be mounted on a table or bench by means of a screw clamp or in any other suitable manner.
The bindingwheel 11 is, for instance,ro--
tated by a handle 13 clamped to the spindle 21, the wheel belng mounted upon the free end of said spindle by means ofa key or of a split-pin 19 passing through its hub 15. The other of the pair of binding wheels12 is adapted to turn freely upon a shaft 26 and is secured against axial displacement by a collar 17 held in place by a split-pin 18. In the embodiment i lustrated in Figures 1 and 2 of the drawing the two binding wheels Well as counter or entrained wheel 12. two wheels may be identical as regards d1- are resiliently forced towards each other in such a way, for instance that the shaft 26 is mounted upon an eccentric disc 27 which by means of eccentric shaft 28 and the springy lever 29 is moved in such a manner that the pressure between bothwheels may vary resiliently. The pressure may be adjusted by a springs29 bearing against a set screw 30 mounted in an abutment 31. Adjacent tothe place of engagement of thetwo wheels there is located an operating table 14 through a slot 33 of which the binding wheels 11, 12 interengage and which serves to guide the superposed sheets of paper to be sticked together. I 1
The binding wheels according to the invention are shown on an enlarged scale in the Figures 3m 6 of the drawing. The wheel illustrated may serve as the driven wheel 11 of the Figures 1 and 2 or equalllly T e ameter, pitch and arrangement of the teeth or they may differ in diameter and arrangement of the teeth.
In the wheel illustrated in Figure 3 of the drawing the teeth are indicated by the reference numeral and themedial part or central portion of the crown of the tooth with the numeral 50. Towards the twofaces 51,
52 of the wheel the central portion of the y flat bevelments, slopes tooth is continued 53, 54. 1
In the design of the wheel illustrated in Figure 4 the teeth are indicated by the reference numeral 66, the medial part or. central portion of the tooth by the? numeral 60, the bevels or,slopes, continuing directly towards both sides with 61, 62. These comparatively fiat inclined bevelments or gentle slopes arecontinued by further steeper bevels\or slopes 63, 64:. By the action of these wedgelike acting bevels or slopes the material located between the upsetting and the counterwheel is compressed in the direction of the middle or central portion of the crown of the tooth ,so that the sheets up to a considerable numberare reliably bound together. It has been ascertained that with the new or improved shape or configuration of the teethas herein desc ribed' the upsetting or compressing pressure may be very considerably increased, for instance by employing very strong wheels together, without a cutting or tearing springs forcing the Figures 5 and 7 at 65.
of the sheets to be bound together. Al-
thou h itis suificient to provide a single beve ent, slope or incline 58, 54 or 61, 62 on each side of the tooth center line,,it is referable to carry out the bevelling or slopmg of the teeth in such a mannerthat t e pressure acting ortion of the tooth, for instance at igure 4, de-
at the central in creases gradually or in steps towards the.
root ofthe tooth.
on an enlarged scale in the Figure 5 in side elevation and Figure 7 in cross-section.
These roundings of the teeth 67 may be semicircular or substantially so, as shown in the This leads to a simple method of manufacturing these wheels, the wheel blank being first shaped along the circumference by means of a tool provided with a concave semi-circular'cutting edge, whereupon theteeth are milled or cut or otherwise produced in this profiled whee'l blank.
It will be understood that the invention is by no means limited to wheels with toothlike rojections only, but is equally well applicalile to other members which may take the place of wheels in the device specified, such as racks or suitably shaped punches and the Various modifications and-changes may be madewithout departing from the spirit and the scope of the invention, and I desire, therefore, that only such placed thereonas are imposed bythe prior art.
