FINISHING 0]? BOOK COVERS.

Application filed November 4, 1927, Serial No. 231,115, and. in Great Britain April 11, 1927.

This invention relates to a machine for laying metallic leaf on the rounded backs of books, of miscellaneous sizes.

The object of the present invention is to provide a machine in which the metallic leaf can be quickly and economically laid, in one or more strips on the rounded back of the book at a single operation.

According to this invention, the machine.

Fig. 3 is an elevation of one plate of the metallic leaf carrying device looking at the inside thereof.

Fig. 4 is an elevation of the other plate of. said device also showing the inside thereof.

Fig. 5 is an edge View of the complete device for narrow metallic leaf.

Fig. 6 is a similar view to Fig. 5 for wide metallic leaf.

Figs. 7, 8 and 9 are an edge view, a side view and a sectional view on line IX-IX respectively of a modified form of metallic'leaf carrying device for wide metallic leaf.

Figs. 10 and 11 are an edge view and a side view respectively of a modified form. of metallic leaf carrying device for narrow metallic leaf.

The machine comprises a rectangular base frame consisting of side members 1, front member 2 and'back member 3. Extending between the side members, perpendicular thereto, are the stationary holding means which are constituted by the clamping members, one 4 of which is fixed and the other 5 of which is slidable towards or away from the one 4. The clamping member 5 is slidably mounted on the frame by lugs 6 extending over the upper and lower edges of the sides 1 and it. is movable by the quick pitched screw 7 operated 'by ahand wheel 8 at the front of the frame.

Pivotally mounted at 10 on the base frame is the rockable mounting means comprising the two upstanding side members 11, atransverse round bar 12 to constitute ahandle, and a transverse framing bar 13. Slides 14 are provided on the members 11, these slides carrying supporting members for the metallic-leaf-carrying devices, which supporting members comprise two spacedtransverse members 15 16, one 15 having a longitudinally extending slot 17. Thus the transverse members will take a required number of said carrying devices and allow them to be fixed at the required distance apart.

The metallic leaf carrying devices may be of two forms, one of which is shown in Figs. 36 and the other is shown in Figs. 7-11.

, In the form shown in Figs. 36, the device. comprises two spaced plates, one plate has a pair of lugs 21 fixed thereto, and these plates are adapted to fit between the frame members 1516 with the lugs 21 in contact with the inner, faces thereof. One of the lugs 21 is tapped at 22 to receive a screw 23 which passes through the slot 17, the tightening or slackening of. which serves to fix the lug to the transverse member or allow it to slide therein. Moreover, by removing the screw the plates can be detached. Thus one plate 20 can be fixed to the transverse frame members, hence this plate will hereinafter be referred to as a fixed plate. The. other plate 24 has slots 25 in opposite side edges, corresponding with the position of the lugs 21 on the plate 20, in which the lugs project, whereby the plate 24 is slidable on the lugs and can move towards the fixed plate. The plates are maintained in the required spaced relationship by means of

sleeves

27 and 28, located on pins29, said sleeves serving as distance pieces, and co-opcrating to this end with the screws 30 and nuts 31. The pins 29 and thereby the sleeves-27 and 28 are not fixed directly to the plates but are fixed to slides 32-33 of dovetail shape mounted to move in correspondingly

shaped slots

34, 35 respectively in the plates, under the control of adjustment screws 36 rotatably fixed on the lugs 42 on the slides and having a threaded engagement with the lugs 43 fixed on the plates 2024. The slides are held in position by the plates 37. A reel of metallic leaf mounted on tissue is indicated by the chain dotted circle 38,thisbei ng mounted on thesleeve 27. The end of the metallic leaf and tissue is secured to the periphery of a roller indicated by the chain dotted circle 39, which roller is mounted on the sleeve 28. A leaf spring is provided fixed on the plate 20 and adapted to bear against the side of the reel so as to restrain movement of the latter, and a similar leaf spring 41 is fixed to the slide 32 and bears against the roller 39 for a similar purpose.

With this form of carrier two sizes of carrier may be suthcient, one such as shown in Figs. 3-5 for narrow reels, and one, such as shown in Fig. 6 (which is exactly the same as that described with reference to Figs. 35 except that the lugs 21 and screws 30 are longer) for larger sizes. Intermediate sizes of reels within the capacity of the two sizes of carriers can be employed by using sleeves of ap propriate width.

In a form shown in Figs. 7-11 in which like references indicate like parts to those described with reference to Figs. 35 with which the plates are very similar but in this case the carriers are made up to suit certain standard widths of metallic leaf, and each carrier takes one standard size only. This may be more convenient in many cases because usually only two or three Widths of leaf may be required. The arrangement differs from the prior arrangement, therefore, in that the fixed plate carries a transverse member 60 to which the movable plate 24 is hinged at 61, and the movable plate is not slotted to engage the lugs 25 but this plate is provided with holes 62 for the passage of screws 63 fixed on the ends of said lugs, fastening members 64 being provided, slotted at 65 to engage with the head of the screw and thereby fix the plate to the lugs, the fastening members being pivotally mounted at 66 so that they can be turned to disengage the screw when it is desired to open the carrier. In this case also the screws 36 are each provided with a reduced shank portion 67 which passes through a hole 68 in the lugs 42 and is provided with an abutment 69 at its end. This allows a bit of play between the screw 36 and the lug 42 which is taken up by theeoil spring 70 located around the screw and disposed between the two lugs 42-43 Further a screw 71 is provided to adjust the tension of the spring 40, which in this case is attached to the slide 33 instead of to the plate, and the spring also engages and is attached to the slide at a point above the plates 37, a screw 72 being provided for adjusting the tension of the spring.

In order to allow for the necessary movement of the slide one of the plates 37 is slotted at 7 3 for passage of the screw 72.

Figs. 10 and 11 show a similar carrier for narrow leaf and in this case, it will be noticed that only a single adjusting screw 36 is provided, this being situated centrally of the carrier and engaging a yoke piece 7 5 connecting the two slides. In this case the slide on the movable plate is detachably attached to the yoke by the pin 7 4t fixed in the yoke and engaging in the hole 76 in the slide. The screw 36 engages with the yoke in exactly the same manner that it engages with the lugs 42 and the spring 70 in this case is located between the member 60 and the yoke.

With the two forms of metallic leaf carrier the action is the same. The arrangement is such that by rotating the roller 39 the tissue and metallic leaf are together wound off the reel, with the metallic leaf on the outer surface of the roller. The metallic leaf is removed in use, as will be hereinafter explained, but the tissue is continuously wound on the roller 39 untilthe reel is exhausted when it is removed from the sleeve 28 and a new reel is fitted. As the tissue is wound 011 the roller, it increases the effective diameter thereof and thereby increases the extent to which the surface projects below the plates, and to compensate for this the adjusting screws 36 are provided, whereby the slide can be retracted periodically and the efiective surface of the roller maintained at about a constant distance from the plate. Moreover, these screws tend to allow for incli- Vidual adjustment of one roller relative to a roller in an adjacent carrier.

As previously stated, metallic leaf carriers, to the required number and at the required distance apart, are fixed between the transverse members 1516. The book is placed between the clamping members and held stationary thereby. The rod 12 is then grasped by the operator and moved forwardly. The rollers of the metallic leaf carriers with the metallic leaf upon their outer surfaces are thus moved into contact with one side of the rounded back of the book, and, thereafter, continued movement of the rod 12 will causethe roller 39 to rotate due to contact with the back of the book, and this rolling will serve to draw the metallic leaf from the reel and to lay it on the book. As the roller moves out of, contact with the back at the opposite or front side, the rotation of the roller will be stopped and owing to the flimsy nature of the metallic leaf further movement of the bar 12 will sever the leaf on the back of the book from the leaf on the roller. Springs are provided between the slides l t and the member 13 said springs serving as loading means and tending to press the slides and transverse members downwardly and thereby press the rollers firmly into contact with the back of the book. Stops 76, co-operating with projections 77 on the slides limit the downward movement of the slides. Having reached the limit of their forward stroke, the slides 14, together with all the parts mounted thereon, are raised by the operator placing his thumbs against the thumb pieces 79 on theupstanding extensions 80 and pressing these upwardly against the action of the springs 75. The operator at the same time moves the bar 12 and its associated parts backwards into their initial position where they are supported by the rest 82. The book can then be removed and subsequently treated at a subsequent and separate operation to the actual finishing operation in which the metallic leaf is permanently impressed on the back of the book.

This is repeated at each operation, and at each operation there is simultaneously laid any suitable number of lines or strips of metallic leaf on the rounded back of the book.

It will be understood that by metallic leaf 1 mean, primarily, gold leaf, but any other metallic leaf can be used which will be similar to gold leaf.
