Application June 15, 1953, Serial No. 361,751

6 Claims. (Cl. 11-1) This invention relates to a method of and apparatus for bookbinding, and more particularly to a continuous method of bookbinding performed by automatic machinery with the object of reducing the cost of the binding operation and obtaining a greatly increased output per operator as compared with known methods.

Another object is to provide suitable apparatus for carrying out the above method.

A further object is to provide a jaw assembly for use in the apparatus just referred to.

Further objects and advantages of the method and apparatus will be evident from the following specification in which is disclosed a preferred form of apparatus for practicing the method. It will be noted, however, that the disclosure made herein is merely illustrative and not limitative of the invention and that changes can be made in the apparatus without departing from the appended claims.

In the accompanying drawings:

Figure 6 is a side view of the jaw assembly in open position, Figure 5, and

Figure 7 is a detail view of the adjustment cams used in the machine Figures 3 and 4.

Heretofore it has been customary in one of the operations connected with the binding of a book to perform what is commonly known as casing in. This operation is usually performed by hand and consists of putting the leaves constituting the book proper within the cover of the book and pasting the first and last leaf to the inside surfaces of the cover. Some paste or glue may also be applied to the back edges of the book and the inside of the cover contacting the same.

The next operation is commonly referred to as building in, and consists of placing the covered books within a tray as shown in Figure 1, in which the books project as shown in Figure 2, so that the metal edges of the tray will form or lie within creases in the cover along the sides of the book. Such creases are commonly called the joint of the book. Pressure is now applied to a stack of books, usually for a period of about eight hours, and the glue or paste is allowed to dry for this period.

It will be noted that this is a batch operation and is performed entirely by hand, the books being loaded into the trays and the trays assembled into a pile so that they can be placed in a bookbinders press. Sufficient time must be allowed for the paste to dry under normal conditions (room temperature).

The improved method herein disclosed comprises the States Patent following steps and greatly increases the speed at which books may be bound.

First, the book cover is applied to the sheets comprising the body of the book in the usual manner, and the cover may or may not have the usual joint extending inwardly from the outside surfaces of the cover and adjacent the back of the book. It will be assumed, for the sake of illustration, that the covers are applied to the books without being jointed.

The second step of the method comprises individually clamping the pages and covers of each book, and the clamping means may form the joint in the covers. These clamps or carriers may be mounted upon a suitable conveyor, as hereinafter described, and any desired member of clamps can be used; only two are herein shown.

The third step consists of applying heat to the exposed cover and leaves of each book while the same are clamped together, as above described.

It will be noted that the leaves of the book are more or less open, thereby permitting the heat to pass upward through the leaves and to the glue holding the cover to the book pages.

The fourth step consists of unclamping the completed book with cover in place.

It will be noted that the above method may be continuous, and a suitable apparatus for carrying out the method will now be described.

Referring to Figure 3, a suitable framework, indicated by the numeral 10, is provided having inwardly extending supports or guide rails 11, for carrying any suitable conveyor such as chains 12, 12a.

The chains 12, 12a, are carried on four sprockets, two of which are shown in Figure 3 at 13, 14; the other two are at the right hand end of the chain in Figure 4, and one of them is shown at 15.

The sprockets 13 and '14 are driven by a shaft 16 in any suitable manner, as by gears 17 and driving shaft 18 connected to a suitable source of power.

It will be seen from the foregoing that the chains 12, 12a, may be driven at any suitable speed, and as best seen in Figure 4 the bottom chain may be made to travel from left to right.

The chains carry a plurality of carriers or jaw assemblies, shown in Figure 4 and in perspective in Figure 5, same being denoted as a whole by the numeral 19 wherever so referred to.

Each carrier comprises a main frame 20 which has at each end the upstanding ears 21 and 22 having

apertures

23, 24, therein to permit the ears' to be bolted to chains 12, 12a, by bolts 25 so that each assembly lies transverse the chains.

One or both of the

apertures

23, 24, can be made slightly oval, or otherwise suitably formed so as to permit the carriers 19 to pass around the sprocket. Any other suitable arrangement for mounting the jaw assemblies on the chains to move therewith can be used.

The main frame 20 of each carrier has two horizontally extending guide pins 26 upon which is mounted in slidable relation the sub-frame 27 which carries at its center portion an upstanding yoke 28 pivoted thereto at 29.

Extending outwardly from the main frame 20 is a laterally extending portion 30 in which is mounted an outwardly projecting rod 31 provided at its outer end with a collar or nut 32 which retains a spring 33 on the rod, the outer end of the spring resting against the collar or nut 32 and the inner end against the upturned extension 34 on the sub-frame 27.

A cam arm 35 is bifurcated at its inner end and is pivoted to the extension 30 of the main frame 20 at 36. This arm carries at its outer end a roller 37 for a purpose hereinafter referred to. V

A bifurcated lever 38 is pivotally connected to the cam arm 35 at 39 and the outer end of this lever is operatively connected to yoke 28 to push outwardly on same when 35 is depressed.

The suband

main frames

20 and 27 of each carrier have outwardly projecting

guide members

40 and 41 to guide the book into and between the jaws 42, 43, immediately adjacent these guides, which form an opening 44 between the jaws, which are adapted to grasp a book with its cover thereon. It will be noted that jaw 42 is on the sub-frame 27, and jaw 43 on the main frame 20.

Referring to Figure 4, the drive shaft 18 being in motion, the chains 12, 12a, are driven by the

sprockets

13, 14, in the direction of the arrow 45; and the chains carry a plurality of the jaw assemblies 19 spaced at desirable intervals therealong.

A cam 46 is provided, pivoted at 47 on the framework and provided with an adjusting cam 48, by means of which the camming surface 49 of cam 46 may be raised and lowered by turning the shaft 50.

The adjustment of the cam 46 may be accomplished in any suitable manner, and Figure 7 shows the arrangement just described. Here the shaft 50, to which the link member 43 is attached (carrying pin 51 engaging the cam 46) passes through a side frame and on the outside of the frame slidably keyed to the shaft 50 is a collar 52 having a handle 53, which when moved radially moves the shaft 50 and its associated link 48, thereby adjusting the cam 46.

The shaft 50 is provided with a lock nut 54 which may have a handle 55 so that when the handle 53 is set at the proper adjustment, the lock nut is screwed up against the assembly locking the shaft 50 in place.

The cam 46 is positioned in connection with the carriers near what may be called a loading station L, and as the chains travel from left to right over the bottom of the sprockets, the carriers pass under cam 46 and the roller 37 on cam arm 35 encounters the cam arm 47 and cam arm 35 is depressed thereby. When so depressed the arm 35, being pivoted at 36 to the main frame 20 of the carrier, pushes the lever 38 forwardly, and said lever pushes against the yoke 28 which carries with it the subframe 27 of the carrier pushing same outwardly against the compression spring 33 thereby forcing the sub-frame 27 outwardly on the guide pins 26, and thus opening the jaws 42, 43, so that these open jaws assume the position shown in Figure 6.

The operator now shoves a book with a cover thereon into the open jaws of the carrier into which the book is guided by means of the

members

40, 41, so that the back of the book fits into the opening 44 between the jaws, where it is tightly held by the spring 33 when the roller 37 is released at the point 56 of cam 46.

The opposed edges of the jaws 42, 43, where they grip the book cover-these edges being shown at 57 and 57a, Figure 6serve, if desired, to make the usual joint in the book cover, forcing the joint inwardly to tightly grip the pages of the book.

It will now be noted, that as seen in Figure 4 the book hangs downwardly in the jaws of the carrier 19 with the pages more or less open, and the book is thus conveyed through a heated chamber 58 in Figure 4, which may comprise an oven equipped with any suitable heater, electrical or otherwise, such as the infra-red lamps 59 which may be positioned in any manner to secure an application of heat up through the partially open pages of the book and toward the back for the purposes of drying the paste between the book and the cover. It has been found that this drying can be accomplished in approximately 45 seconds for the average book, whereas heretofore the books when clamped as shown in Figures 1 and 2 require eight hours for drying.

The books, after passing through the. heat zone 58, are conveyed to what may be termed an unloading station, at which is located a cam 46-2 with its associated adjustment exactly as described in connection with the cam 46. It will be obvious that when a carrier 19 runs under the cam 46-2 that the lever 35 will be depressed and the jaws 42, 43, released to permit the removal of the book cover from the jaw assembly.

The carrier 19 then continues up and around the sprockets 15 at the right-hand end of the machine, Figure 4, and is conveyed to the left, and the operation just described repeated, thus permitting the feeding of the books to be bound in a continuous operation.
