JAMES B. ALLEN AND HARRY D. MORTON, OF DETROIT, MICHIGAN.

BINDING APPARATUS.

To all whom it may concern Be it known that we, JAMES B. ALLEN and HARRY- D. MORTON, citizens of the United States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Binding Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to apparatus for threading flexible cords through apertured bodies, being more particularly designed for use in connection with the binding of pamphlets.

In the present state of the art, pamphlets are frequently bound by loops of cord passed through a series of apertures in the leaves and tied to form a bow-knot. This work is usually performed by hand and is a slow and tedious operation.

It is the object of the invention to provide means for threading the cords through the entire series of apertures in a single operation so that the only hand work required is the tying of the bow.

It is a further object to associate this threading device with the punching machine for forming the apertures so that the work delivered from the punching device is in position for engagement with the threading device.

In the drawings,Figure 1 is a section through the threading device; Fig. 2 is a sectional perspective view showing one of the jaws of the threading device; Fig. 3 is a section similar to Fig. 1 showing the parts in a difierent position; Fig. 4 is a perspective View of the complete work; Fig. 5 is a side elevation of the machine having a punching and threading device associated.

Generally described, the improved device comprises a channel member adapted for registration with the apertured work to form a continuous passage between a plurality of the apertures and pneumatic means for forcing the string or cord through said apertures and connecting channel. Preferably the stringing is efl'ected by suction and by simultaneously drawing in the opposite ends of the string or cord to form a loop.

In the specific construction shown, A is a suction head, B is a bed or support for the work which is provided with channels C therein for connecting pairs of apertures through which the cord is to be looped.

Specification of Letters Patent.

Serial No. 699,621.

These channels C are preferably in the form eration the bed B is preferably formed in H separable sections and the channels 0 are formed in the adjacent face of said sections so that when the latter are separated the loop may be readily disengaged.

As shown in Fig. 2, the pamphlet to be bound is provided with three apertures, the binding cord having its opposite ends drawn through the outer apertures and together passed through the central aperture. The supporting bed B is in the form of an angle guide upon which the open book or pamphlet is placed, and the suction head is provided with corresponding angling faces having a yieldable resilient gasket D thereon which when pressed against the work upon the guide D will form an air tight joint.

gasket D as indicated at F, which prevents the accidental drawing of the cord completely through one of the apertures and into the suction head.

The supporting bed or guide member B has one of the sections thereof fixed while the other section is hinged and is movable preferably by a foot lever G and cooperating spring G into and out of contact with the fixed member. The same movement lowers the suction head and clamps the work previously registered with the channels in the guide. The work may be fed into registration directly from the punching machine by providing a continuous guide H therebetween so that after the completion of the punching operation the work may be slid along and into registration with the channels in the guide. Thus one operator can punch the leaves and another operator can thread the cords, the work being carried on continuously without interruption.

What we claim as our invention is:

1. The combination with a member having a channel therein for registration with separate apertures in the work, of pneumatic means for stringing a cord through said apertures and connecting channel.

2. The combination with a channeled member having the opposite ends of the channel registerable with separate apertures in the work, of a suction head for covering one of said apertures to draw a string through the other aperture and connecting channel and out through the first mentioned aperture.

3. The combination with a member having a channel therein, the opposite ends of which are registerable with separate apertures in the work, of a presser foot for holding the work in contact with said member, and suction means carried by said foot registering with one of said apertures.

4. The combination of a work support formed of separable members having a channel formed in their adjacent faces, the ends of which are registerable with separate apertures in the work, of pneumatic means for threading the cord through one of said apertures and connecting channel out through the other aperture, when said sections of the work support are together, the thread loop being detachable from said work support upon the separation of the members thereof.

5. The combination of a work support in the form of a saddle comprising two separable members having channeled adjacent faces with the ends of the channel registerable with separate apertures in the work, a movable head for clamping the work upon said support, and pneumatic means carried by said head and registerable with one of the apertures in the work for threading a string through said apertures and connecting channel.

6. The combination of a work support comprising a saddle formed of members separable in the plane through the apex of said saddle and having their adjacent faces channeled to form a loop registerable with separated apertures in the Work, a clamping head for the work upon said support movable into and out of engagement therewith and having a suction head registerable with one of said apertures, means for moving said head, and co-acting means for separating the sections of said bed when said head is raised.

7. A work support having a plurality of loop channels therein for registration with a plurality of separated apertures in the work and provided with a common aperture therein, a work clamp having a suction head registerable with said common aperture and constituting a holder for a loop of cord, said suction head being adapted to draw the opposite ends of the cord through said separated apertures, and connecting channels into said common aperture and suction head in through said separated apertures and connecting channels into said common aperture and suction head.

In testimony whereof we affix our signatures in presence of two witnesses.
