PROCESS OF MAKING BOOKS AND COVERS.
Original application filed October 11, 1918, Serial No. 257,706. Divided and this application d November 18, 1921.
To all whom it may concern:
Be it'known that I, HENRY C. EGERTON, a citizen of the United States,'and now a resident of Passaic, county of Passaic,-State of New Jersey, have made acertain new and useful Invention Relating to Processes of Making Books and Covers, of which the following is a specification, taken in connection with the accompanying drawing.
This case is a division of my copending application Serial Number 257,706, filed October 11,1918.
- This invention relates especially to processes of'making books or detachable or other book covers for large or heavy books. The cover back which may be of canvas or other suitable fabric may, if desired, be toughened and strengthened against, wear by being impregnated or coated with rubber or other suitable material and this back member may have integral attachingportions cemented or otherwise secured to the covers; n The book covers may, if they are to withstand hard usage, be advantageously formed of canvas or other fabric or material carrying phenolic condensation cementing material, and a number of superimposed layers of canvas, paper or other fabric, may beusimultaneously stiffened, strengthened and secured together and cemented to the back member by such heat and pressure curing methods as are adapted to mold and harden such ce menting material as bakelite, condensite or redmanol varnish compositions. It is quite advantageous in some cases to have vulcanized rubber portions or wear resisting members incorporated with the book covers,
and corners or other members thereof may be advantageously secured to the book covers by the same heat curing treatment which cures and solidifies the phenolic condensation cementing material, if desired, Detachable book covers of this general construction may be formed with flexible securing flaps or members attached to the back and cover members and a fold of the back fabric maybe utilized for this purpose, preferably after being coated or impregnated with suitable toughening, strengthening material, such as a light coating of vulcanized rubber, or if desired,.a speciallysoft flexible phenolic COIldQIlSfltIOI), cementing mafiled Serial No. 516,085.
terial comprising castor oil or other suitform of book cover.
Fig. 2 is an enlarged transverse section thereof, parts being shown in'separated position for greater clearness.
Fig. 3 is a sectional view through another book construction; and
Fig. dis a corresponding enlarged detail,
parts being shown in separated position.
As indicated in Figs. 1 and 2, the book back 3 may be formed of one or more layers of canvas or other suitable fabric which may have folded or other attaching portions, such as 7 8, adapted to be cemented or otherwise attached or secured to the book covers. Phenolic condensation cementing material :may be advantageously used for this purpose, particularly if the book covers are formed of paper, fabric or other fibrous material carrying or more or less impregnated with such cementing material. -A convenient way of forming such attaching portions is to form folds 7, 8 on either side of the book back and coat or impregnate such attaching folds with phenolic condensation cementing material of any suitable character, such, for instance, as bakelite varnish No. 1, which may be conveniently dried at moderate temperatures of 175 to 200 F. ,Such impregnated or coated attaching folds. may be securely cemented to the cover which may be formed of or com prise one or more layers of similarly impregnated canvas or other fabric or, if desired, paper, cardboard, or other fibrous material which is preferably sufficiently impregnated or coated with such cementing material so as to be suitably stiffened and strengthened thereby as well as cemented to the other parts of the cover. As indicated in Fig. 2 the covers may, if desired, comprise the canvas layers 10, 11, which may be formed by folding a single sheet of immediate layers 12 of canvas or other fabric, such as paper, etc. which may extend adjacent the edge of the attaching folds 7, S to make the cover member of substantially uniform thickness.
This entire cover member may be cemented together and moulded in shape, and if desired embossed and ornamented, in a suitable mold or press in which it can be submitted to the desired curing heat of 250 to 320 F. more or less for half an hour or an hour or so until the phenolic condensation cementing material is cured preferably under pressure so as to securely unite all of the parts and force the cementing material uniformly therethrough which gives an extremely strong union and greatly stiffens the cover elements. For some purposes it is desirable to incorporate vulcanized rubber members or portions on the cover, such, for instance, as corner reenforcements 13, which may be carried up around the edges as at 14 in Fig. 2 and a similar vulcanized rubber re-enforcing strip 15 may be used, for instance, at the inside edge of the cover adjacent the back. Sheets or layers of such material may be arranged 1n proper place on the book covers when they are submitted to such a pressure heat curing treatment. A connector strip such as 16 of relatively thin canvas or other fabric, and which may have a frictioned or other rubber coating 17 previously provided thereon adjacent the layer 15 of vulcanir able rubber, may be used to promote the union of the rubber to the other elements, the phenolic condensation cementing material sufficiently engaging and entering this connector fabric during the molding and curing operation to secure it firmly in place. Such a cover may of course be cemented or united at the same time its elements are cured to the ordinary securing flaps or portions of a book body of any suitable character, or if desired, it may be used as a detachable book cover, in which case it is usually desirable to form thereon special disengageable securing flaps or members. For this purpose the back fabric may, for instance, be formed with a single or double fold or flap such as 4, 5, which may be carried up adjacent the inner edge of each cover member and if desired have an attaching portion 9 extending under one or more of the layers of cover fabric 11. This securing flap is of course preferably relatively flexible, but may advantageously in some cases be strengthened by impregnating or coating it with a suitable rubber composition which may be vulcanized during the heat curing process, or if desired, such flaps, which may in some cases be providedwith eyelets or lie-enforced apertures 6, may be coated or impregnated w tlra specially flexible phenol-1c condensation cementing material, such, for instance, as bakelite varnish N0. 1 with which has been incorporated suitable proportions of softening agents such as analin, waxy, fatty or oily material, such for example, as 20 to 35 per cent by weight of castor oil which readily unites when mixed with moderate heat with such cementing material. By applying such special phenolic condensation cementing material to the fabric and forcing it into the same preferably when moderately heated the desired degree of penetration or impregnation can readily be secured and when heated for a suilicient time this cementing material is permanently cured, although it retains, however, considerable flexibility, so that the fabric is not unclesirably stiff and brittle if sutlicient softening material has been used. If desired, the back member may be originally impregnated or coated with such special soft curing bake lite or other phenolic condensation cementing material throughout the back and securing flap portions, and if desired heat cured or treated so as to complete these parts before or after the other parts of the fabric constituting the attaching portions are impregnated with regular hard curing cementing material of this general character and cured and cemented to the other co-operating book elements.
Figs. 3 and at show another arrangement in which a regular book body 22 which may have the ordinary tapes 23 and connecting fabric 24 attached thereto so as to form projecting attaching edges 25 of these fabrics, may be bound in a special book cover and back of this general construction. The cover members 20, 21 may be permanently or temporarily connected to a fabric or other back of canvas or other suitable material which may be coated or impregnated with rubber or soft curing bakelite or other phenolic condensation cementing material if desired. These cover members may comprise the superimposed canvas or other layers 26, 28 on the outside thereof and one or more intermediate layers 27, 2t of canvas or other cloth, paper, etc. carrying sufficient phenolic condensation cementing material so that under the heat and pressure curing treatment all the parts are permanently cemented together and the fabric sulliciently stiffened and strengthened so as to be desirable for this service. In some cases the cover members may be temporarily connected with the flexible back as by sewing or by partially curing the phenolic condensation cementing material they contain while leaving one or more of the cover layers such as 28 in relatively uncured condition so that they may be bent back preferably when somewhat softened by moderate heating to insert the attaching ends 25 of the book; tapes or other securing Ill) ; bodiments, forms, proportions, elements,
parts, shapes, materials, compositions, and methods of preparation, production and use, to the details of which disclosure the invention is not of course to be limited,
sincewhat is claimed as new and what is desired to besecured by Letters Patent is set forth in the appended claims.
