P. A. FRAZIER manna FOR PRESSING BOOKS Filed Nov. 1, 1928 4 Sheets-Sheet 4 jf zrenfol n PZZZZyJJZ. E?(6ZZ67 Patented July 21, 1931 UNITED "STATES PATENT OFFICE PHILIP A. FRAZIER, OF CHICAGO, ILLINOIS, ASSIGNOR TO B. R. DONNELLEY & SONS COMPANY, OF CHICAGO, (ILLINOIS, A. QORPORATION OF ILLINOIS MACHINE FOR ,rn'nssme BOOKS Application filed November When these books emerge from the binder,

the glue which is applied hot has not had time to become set, and the present machine for pressing these books is intended to thoroughly press and mold them for a short interval after leaving the binding machine so as to .hold them accurately in proper shape during the time when the glue is setting.

These and .,other objects, as will hereinafter appear, are accomplished by this inven tion which is fully described in the following specification and shown in the accompanying drawings, in which F gure l is a partial side elevation of a machine embodying the present invention;

Fig. 2 is a top plan view of the same showing the relation of this machine to the packer; Fig. 3 is a partially enlarged section on the line 3-3 of Fig. 2; v V t Fig. 4 is a partially enlarged detail of the chain links and plates carried thereby; Fig. 5 is a partially enlarged section on the line 5-5 of Fig. 1; and

Fig. 6 is a section on the line 66 of Fig. 5. The embodiment illustrated comprises a book pressing machine A shown in Fig. 1 as receiving a book B from a book binder C. Figs. 2 and 3 show the machine A for pressing books. and delivering them' to a. well known form of packer D by means of a plunger or pusher 'E.

The book pressing machine A consists essentiallyof two inner chains 10 which mesh with sprockets 11 and 12, these sprockets being journaled in bearings 13 which are sup ported in any suitable manner from the main frame of the machine. Each sprocket is double-ended, as shown in Fig. 5, and has a 1, 1928. sem No. 316,527.

longitudinal opening axially therethrough, which is tapered at its ends to receive a tapered portion 14 of the shaftsl5 and 15 of the sprockets 16 and 17. The meeting ends of the shafts 15 and 15 are provided with dental clutchteeth 18, as shown in Fig. 6, and the two portions are secured together by means of a cap screw 19. The shaft 15 is provided with an extension 15 by means of which it is driven from any suitable source of power in timed relation to the feeding of the book binder C.

The sprockets'16 and 17 carry sprocket chains 20 which lie outside the sprocket chains 10. The chains 20 have links with inwardly extending cars 21 to which are secured plates 22. Similarly formed plates 23 are secured to the chains 10. It willthus be seen that by loosening the screw 19 the sprockets 11 and 12 may be moved with respect to the sprockets 16 and 17 so as to vary the distance between the plates 22 and 23. To assist in this operation, I have provided openings 11 and- 16 in the sprockets 11 and 16, respectively, so that a small pinch bar or the like may be inserted for greater ease and accuracy in moving these sprockets with respect to each other for the purpose of ad-,

Justment. p

The book pressing machine A is timed with respect to the book binder C, so that each book B is released fromthe binder C by means of a cam 24 over which rides a cam follower'25 ofa plunger 26, which thereby forces a gripper 27 outwardly, thus releasing the book B which then falls to the dotted line position B in the machine A. At this time the plates 22 and 23 are separated, as shown on each side of the dotted line position B owing to the fact that the plates are held apart because of the curvature of the chain in passing around thesprocket. The upper portion of the chain moves to the right, asin'dicated by the arrows in Fig. 1, so that the two chains '10 and 20 become straightened. The book now in the position 13 is held and pressed by the plates 22 and 23,'and this pressing continues until'the books are discharged from the machi e as will now be described;

in contact with I The dischargingmechanism, as shown in Figs. 2 and 3, consists of a plunger 28 WhlCh reciprocates once for each four books carried by the plates 22 and 23 and has four v books already held under the finger 32 are pushed forward. The operator then removes the books from the far end of this pileof books which is not shown, or they may be disposed of in any other manner.

It is necessary that the plunger 28 be moved forward with the hooks B while these books are being forced from between the plates 22 and 23, thereby necessitating that the plunger 28 having a diagonal motion. This is accomplished by providing a cam roller 33 which is journaled upon a pin 3 on the bottom side of the plunger 28. This cam roller follows a cam groove 35, 36, 37 in a plate 38' suitably mounted upon standards 39. The plunger 28 is moved forward by means of a cam 40 on a shaft 41 which is driven in timed relation to the shaft 15 of the pressing machine A and makes one revolution for each four books.

The cam 40 acts through a cam follower 42 to move a lever 43 which is fulcrumed at 44 from the full line position of Fig. 3 to the dotted line position. In doing so, the cam roller 33 follows the diagonal groove 35 which is so formed that the plunger, fingers 29 press directly against the ends of the books B but travel' along with them. At the end of the stroke the cam roller 33 is caused to follow the return cam groove 36, and thence back to the groove 37 to the starting point by means of spring operated mechanism which will now be described.

Theoperating lever 43, together with the plunger 28, is also returned to the full line startlng position by means of a spring 45. A cam roller 46 is mounted upon a pin 47 on the upper side of the plunger 28 and engages a straight cam groove 48 in a bar 49 which is provided with a central pivot'50 slidably mounted in a transverse slot 51in a transverse member 52 carried by the plate 36. The bar 47 is normally held in the position shown at the right hand end against a stop 53 and the left hand end is held ahnost a stop 54 by means of; springs 55 and 56.

As the plunger 28 is pushed forward from the full line position shown, the cam roller 46 rides up along the groove 48, thereby tensioning the spring 56 and ensuring that the cam roller 33 will travel back along the cam groove 36. As the left end (Fig. 3) of the cam groove .36 is approached on the return stroke, the spring 55 is placed in tension, thereby causing the cam roller 33 to travel back along the cam groove 37 to the starting position shown. The plunger 28 is extended beyond the paper at the left and guided to' 7 ing also gives the book a more regular and compact form and even this short interval enables the glue to cool and set somewhat so as to provide a stronger and firmer book than would otherwise be obtained.

While I have shown and described but a single embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as covered by the appended claims. a
