CHARLES H. ZEIVIKE, OF CHICAGO, ILLINOIS.

DEVICE FOR APPLYING PRINTED MATTER TO EDGES OF BOOKS AND THE LIKE.

Specification of Letters Patent.

Patented Nov. 2 5, 1919.

7 Application filed. March 19, 1918. Serial No. 223,343.

To all whom it may concern:

'Be it known that 1, CHARLES H. ZEMKE, a citizenof the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Devices for Applying Printed Matter to Edges of Books and the Like, of which the following is a specification.

My invention relates to improvements in devices and processes for applying printed matter to the edges of books and the like.

The application of printed matter to the edges of books and the like is effected, at the present time, by means of stamps or other impression devices, which are pressed against the edges of the books. The edges of the book however, are not smooth and even,'the same being grooved or channeled due to the non-alinement, no matter how slight, of the leaves comprising the book;

and for this reason it has been found that where printed matter is applied to the edges of the book through an impression element, only the high spots or lines on the surface engaged receive the ink or pigment, with the result that a pale or indistinct imprint is produced.

It is the object of this invention to provide a means and process for applying printed matter to the edges of books and the like which, notwithstanding the uneven or irregular character of the surface acted upon, as above mentioned, will at all times produce clear and distinct letters or characters upon the surface engaged. A further object is the production of a device of the character mentioned, which will be of durable and economical construction and highly efiicient in use.

Other objects will appear hereinafter.

The inventionconsists in the combinations and arrangements of parts hereinafter dcscribed and claimed.

The invention will belbest understood by reference to the accompanying drawings forming a part of this specification, and in which, V

Figure 1, is a sectional perspective view of a device embodying the 1invention,-and,

Fig. 2, a front elevation of one of the stencils of the device detached.

The form of the invention illustrated in the drawings is shown applied to the dis charge conveyer of a conventional book gatheringa ,.-n mmie mac ine th m comprising a table or platform 4: along which the books 5 or other articles to be acted upon are moved in the operation of the machine.

The mechanism forming the subject matter of this invention comprises a pair of stencils 6, which are arranged at opposite sides of the conveyer platform 4, said stencils being carried by swingingly mounted arms7 which are fulcrumed at 8. The arrangement is such that said stencils are adapted to move toward and from the 0pposite sides of the conveyer platform in order to engage with the opposite edges of a book positioned thereon, as seen in 1 of the drawings.

The outer side of each stencil is inclosed in ahood 9, into which projects a spraying device '10 held in fixed relation with the stencil by means of a rigid. supporting bracket 11. The ink or other pigment employed, is fed to the spraying devices 10 by means of flexible pipes or hose 12 which communicate with a common supply pipe 13 leading to any suitable source of ink or pigment supply under pressure. Discharge from the spraying devices 10 is controlled by normally V operating handles 15 which are positioned in the paths of'movement of the arms 7. The arrangement is such-that the valves.15 will. be closed, and hence discharge from the spraying devices 10 prevented, except when the stencils 6 are in operative relation with the edges of the book acted upon, the valve handles 15 being so arranged that as the arms 7 swing to operative position, carrying the stencils into engagement with the opposite edges-of the book, said handles will be rocked to open position. As said arms 7 move outwardly carrying the stencils away closed valves 14 having oscillatory U from the edges of the book, handles 15 will automatically swing to closed position.

The arms 7 and hence the stencils 6 are normally held in operative position by means of helical tension springs 16 which engage with said arms, as clearly seen in Fig. 1. Intermittent movement of the stencilstoward and from the opposite sides of theconveyer platform in'order to effect suca certain point in its travel along the platvalves 15 will be simultaneously opened,

causing the discharge of the ink or liquid pigmenttoward said stencils, with the result that the desired printed matter Which has previously been formed in the stencils, will. be applied to the opposite edges of the book. The operation will be practically instantaneous, the stencils, after the stenciling operation, as described, being moved outwardly by the cams 17 Each of the successive books will be thus engaged, the timing of the operations of'the various parts being such as to effect this purpose.

The force of the spray of ink or pigment directed against the edges of the books through the openings in the stencils, will insure the complete covering of the portions of the edges exposedor registering with the openings in the stencils, notwithstanding irregularities in said surfaces suchas may be due to non alinement oirthe leaves of a book, and the work produced will be distinct and clear-cut. 1

At the bottom of each hood 9 is provided a drain trough 19, into which the ink or liquid pigment not applied to the edges of the book engaged will flow. and be drained back through a suitable pipe or other pasto the source of ink or pigment The production of a pair of stencils engaging with opposite edges of the book is of special advantage in that with this arrange-- ment each stencil serves as a brace for the book against the pressure of the other stenoil, the book being held securely between the two stencils which engage simultaneously therewith. Although but a single hook is shownin the drawing and the stencils are designed to engage with only one book at a time, it is apparent that the stencils may be increased in width or height to form a multiplicity of stencils in order to cooperate with a plurality of books piled one upon the other, such as is frequently the case where the bookshandled in a machine of the character under consideration are comparatively narrow.

While I have illustrated and described the preferred form of construction and process 5 I claim as new and desire to secure by Letters Patentis:
