8 Claims.
Our invention relates to improvements in book folding machines, and more particularly to that type of book folding machine adapted for use in the manufacture of blank books and note books,
similar to those in use extensively in our public schools, as well as private schools and colleges.
An object of our invention is to provide a book folding machine which will automatically fold the book, and press, or set, the fold, after the book has been folded, so that the folded books may be stacked, or piled, conveniently, without tipping, or sliding.
A further object of our invention is to provide such a machine, which may be used efficiently, as
' an individual unit, or in co-operation with book stitching or stapling machines, and also, in cooperation with book binding, or taping machines.
This invention is also an improvement in the folding unit of the book stitching and folding machine disclosed in Patent #l,937,979, issued to Wellington George Reynolds, dated December 5, 1933.
It has been customary, in the trade, to use a separate machine for folding the books and a separate, or different machine, for pressing the books, after folding, requiring manual handling from one machine to the other, between these operations. It-is an object of this invention to combine the operations of folding and pressing in a single machine.
These, and other objects and advantages of our invention, will be more completely disclosed and described in the specification, the accompanying drawings, and the appended claims.
Broadly, our invention comprises a machine having a folding table, provided with a folding slot, carrier belts for conveying the leaves of a book to be folded onto the folding table, a folding blade, means for operating the blade for forcing the leaves of a book through the folding slot and thereby folding thesame, adjustable and movable press blocks below the folding table, 'means for positioning the folded book between the press blocks, feed rolls for moving the folded book from 5 the folding slot to the positioning means, means for operating one of the press blocks for pressing the folded book, and carrier belt for removing the folded and pressed book from the machine.
A preferred embodiment of our invention is illustrated in the accompanying drawings, in
which:
Fig. 1 is a plan view of the machine. ,Fig. 2 is a rear elevational view.
Fig. 3 is a sectional view on the line 33 of 55. Fig.2.
Fig. 4 is a sectional view on the line 4'4 of Fig. 2. V
Fig. 5 is a detail view, illustrating the mechanism for holding the leaves and cover of a book stationary on the carrier belts, until the proper 6.. time formoving the book onto the folding tabla Fig. 6 is a sectional view on the line 6-6 of Fig. 5. j a
Fig. 7 is a view similar to Fig. 6, showing the stop pins raised, before the book has completely 10- passed them.
Fig. 8 indicates the unfolded book, and
Fig. 9 indicates the leaves'ofa folded book; before it is cut into the required book lengths.
Referring now to the drawings in detail, in.l5 which like numerals refer to like parts throughout:-
Frames I and 2 have supported thereon plates 3 and. 4, (see Figs. 1- and 4), which are spaced from each other to form a folding slot 5. The 20 plates 3 and 4 co-operate to form a folding table upon which the leaves and cover of a book, to be folded, may be placed ready for the folding blade. Side frames, or arms 6 and I, secured on the frame I by brackets B and 9 (see Fig. 3), support a belt 251 roll Ill; The roll I0 is driven, by means of gears I I, shaft I2, and universal joints l3, from a main drive shaft I4, supported in' the frames I and 2, and having mounted thereon a drive pulley I5.-
Carrier belts I6, II, I8, and I9, supported between Fig. 8, is placed on the carrier belts I6, II, I8, and 40 I9, between the upright guides 2| and'22, it willbe moved by the belts toward the folding table, comprising the plates 3 and 4, having the slot 5 in which a folding blade-operates.
In order to properly time the arrival of an un- 45 folded book onthe folding table, movable st'op pins, or studs 21, are provided against which the forward edge of a book, approaching the folding table, impinges, thus holding the book back, until the stop pins are moved out of engagement with 50. the unfolded book. The construction and operation of this timingmechanism is best illustrated in Figs. 5, 6, and 7. A shaft 23, revolvably secured in bearing members 24, secured on a plate 25, supported on-the framemembers 6 and :I, has I adjustably secured on the plate 3.
7 face of a cam 32 by a contractile spring 33. When' 10 the extended portion 3310f the cam 32 engages V the lever 30, the shaft 23 isosoillated to bring the studs 21 below the carrier belts, as shown by dotted lines in Fig. 6, which are ,then free to carry the unfolded book onto the folding table '3 and '4. In order to provide for varying lengthsof books,
this operation is timed to bring the studs 21 back into holding position, before a book, being carried to therfolding table, has completely, or fully, passed over them, as indicated in Fig. 7. This arrangement also insures that, if adjoining, or
following books, are closely spaced, or even butted together, the following book will be stopped by the raised studs 21. cured on a cross bar 35, supported on the members 6 and 1 by the posts will prevent a book from jumpingj, or passing over, the-pins 21. The cam 32 is secured on an end of a cam shaft 36,'which is operatively connected to the drive shaft l4 by gears 31, 38, 39, and 46. (See Figs. 2
3 and'3.) 9 7 p a Y As an unfolded book 43 is released by the stop .pins or studs 21, it is carried onto the plates 3 and 4,.by the belts |6, I1, |8, and'|9, and is stopped in proper position-by a stop plate 4| The end stop member 4 ,and a side guide member 42 also adjustably securedon the plate 3, may be set to the .exact dimensions of thebook to be folded. After an unfolded book 43, indicated by -dotted lines'in Fig. 1, has been carried against the end stop member 4|, a' movable centering member 44 is movedagainst the edge of the book to push it against the member 42, thus accurately centering the book over the folding slot .5. As
45- shown in Fig. 4,'the centering member is adj justably secured to a plate, or bracket 45, by V arms 46.* The plate 45 issecured on a bar 41,
which is slidably supported in bearings 48,'on the, under side of the table plate 4. 'An operating -lever 49,-pivotally supported on a shaft 50, is operatively connected to the bar 41, and bears a cam roll 5| which is maintained in operative engagement with'a cam 52- by a contractile spring 7 53. The cam 52, through'the roll 5| and lever 49,'moves the bar to slide the guide 44 forward and backward on the table plate 4. a After the unfolded book 43 has been properly positioned on the folding table by the members 7 4|, 42,-and .44, a folding blade 54 is caused to descend, engage the leaves and cover of a book on its center, line, and force the leavesand cover of thebook through the folding slot 5. The blade 54 "is secured in bracket members 55, which are adjustably secured, by means of the bolts 55', on vertical shafts56 that are slidably supported in bearing boxes 51 on the frames'l and 2. The shafts 56 are connected, by link members 58, to
. operating arms 59, which are pivotally secured at r66 on the frames and 2, as shown in Fig.3 The; arms 59'are actuated by links 6|, connected to cranks 62, secured on afeed'roll shaft 63, which is operatively connected to the drive shaft through gears 64.and 48, As the shaft 63re- 7b. volves,,the arms 59 are caused ;to oscillate, thus Depending'guide bars 34, se-
(See Fig. 1)
moving the shafts 56 up and down, and raising V and lowering the folding blade 54.
After passing through the folding slot 5, the folded book is then engaged by feed rolls 64, operably connected by gears 65 and 66, and the feed rolls 64 then carry the folded book downwardly between the faces of the two press blocks 68 and 69, until its folded edge rests upon a gate member 18. The rolls 64 are formed with flat sides 61,
for the purpose of providing a dwell period during tion of the cam shaft 36, until pressure is exerted on the book between'the faces of the blocks 68 and 69. The blocks 68 and 69 are slidably supported in slots 13, formed in the frames and 2. The book, as it passes between the rolls 64,is guided into the'space between the'blocks 68 and 69 by a guide strip 14, secured on the top of the block 68. means of adjusting screws 15, which are caused to movesimultaneously by a connecting chain 16, for the purpose of maintaining the face of the block 68 parallel to the face of the block 69. The pressure exerted on a book, by the feed rolls 64, may be varied by adjusting screws 11. These adjusting means for the block 68and rolls64 also provide for variations in the thickness of the books. g
After the folded book is pressed, the gate 18 is folded and pressed book from the machine. gate 10 is pivotally secured by hinge members 19 to the movable block 69, and has secured-thereto an operating rod 88. A cam arm 8|, pivotally supported on the shaft 50, and carrying a cam roll 82, which is engaged bya cam 83 on the shaft,
movement of the block 69 and cam 83, due to the different timing required for each. A contractile Adjustment of the block 68 is provided byopened to permitthe book to drop throughonto I r t "a carrier belt, or belts 18, which will remove the The spring 86, secured to the arm 8| and the block 69,
holds the camroll 82 in engagement with the cam 83. V 'p 7 w In operation, an unfolded book 43 is laid, or otherwise placed, on the carrier belts |6, H, M,
and I9, and is carried toward the folding table,
until halted by the studs 21, which hold it sta-' tionary, until the folding blade 54 is raised above the foldingtable. The stop pins, or studs 21, are
' then actuated, or lowered, to release the unfolded book, which is. carried onto the folding table against the plate 4| by the carrier belts, and centered laterally over the V folding slot 5 by the stops 4| and 42 and the centering member 44. The blade 54 then'desce'nds, carrying the book with it, through the folding slot 5 and'thus'folding the book, which is then picked up by the feed rolls 64 and deposited on the ga te 10, between the blocks 68 and 69. The press block 69 isthen moved forwardly, pressing. the book between itself and the block 68, and then moved back again to free the folded and pressed'book. The gate'10 is then openedto permit the book to drop,-or slide, down onto the removing belt'18.
Fig. 8 shows the leaves 81 of the unfolded book with a center line of stitches 88. Fig. 9 shows the leaves folded on the center line of stitches. The lines 89 indicate the lines where the folded leaves are to be cut, in order to form three of the folded books, 90, 9| and 92.
