Application filed January le', 1919. Serial No. 271,472.
To all whom it may concern employing a suitable fibrous material, pref- Specification of Letters Patent. P t Jan Be it known that I, JOHN GEORGE MILES, erably in sheet form, impregnated with a a. citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have in- Vented a new and useful Improvement in Book-Covers, of which the following is a specification.
My invention relates to book covers or loose-leaf binder covers, and it has, for its primary object, the const notion of such articles by employing layers of fibrous material impregnated and united by a suitable adhesive adapted to harden. under heat and pressure.
-Heretofore, articles of the above designated character have been constructed of materials which, though satisfactory for a certain length of time, have a tendency to Warp and consequently reduce the length of time of their usefulness. In view of this, one object of my invention is to construct covers of a material which will not warp under any climatic conditions and which will not soften or mash at the corners and edges.
Another object of my invention is to con-- struct book covers or loose-leaf-binder covers of a material which acquires a high polish. and decorative finish during the ordinary course of its construction.
A still further object of my invention is to provide loose-leaf-binder covers constructed 'of material which may have suit able 1 metallic hinge members riveted or otherwise secured thereto without employing reinforcing eyelets and which will thus simplify the construction of such artlcles.
With these and other objects in view. my invention will be more fully described, illustrated in the drawings, in the several views of which corresponding numerals indicate like parts, and then particularly pointed out in the claims.
In thedrawings, Figure 1 is aplan view of a loose-leaf binder embodying my invention; Fig. 2 is a sectional view taken substantially along the lme II-II of Fig. 1: Fig. 3 is a plan view of a modified form of loose-leaf binder embodying my invention, and Fig. 4 is a sectional view taken along the line IV IV of Fig. 3.
In practising my invention, I may construct a book cover or loose-leaf binder by suitable mold to compact the material and to harden the binder. The sheets may be cut to the form of the plate ultimatelv desired or they may be stacked and the binder hardened and then machined to form. as desired,
However, I prefer to form the sheets before they are stacked and pressed. A .plurallty of composite plates thus formed mav have suitable hinge members secured to the sides thereof by riveting or otherwise fastening them to the plates.
In Fig. 1, is shown a book cover 1 comprlsing two composite plates 2 and The composite plates 2 and 3 may beformed by employing a suitable sheet material such "as duck, muslin or paper and the sheet material may be impregnated with a binder such, for example, as a phenolic condensation product. The'sheets comprisingthe plates 2 and 3 are preferably cut to form before being stacked and they may beimpregnated before before being cut. if desired. as the .binder may be suflicient ly heated to render the sheets dry .enough to be readilv handled, the binder being then in 'an in active or intermediate state. The impreg' nated sheets are stacked to a suitable thickness after which they are subjected to heat and pressure, in a mold. to compact them andto harden the binder with which thev are impregnated. t
In thisinstance. eaci plate has a corner covering 4 of leather and. a hinge member 5 of pliable material. such as soft leather, glued or otherwise fastened .to the plate. The hingemembers may be connected with suitable threaded members 6 and sleeves 7 adapted to inclose the threaded members 6. In Fig. 3, a loose-leaf-binder cover 8. here shown, comprises a plurality of plates 9 and 10 constructed of fibrous material impreg' nated with a hardened phenolic condensation product. In this form of loose-leaf binder cover, the hinge members 11 are fastened to the plates by merely riveting the members to the bare plates. On accountof the exceptional mechanical strength of the fibrous material, impregnated with a bardened phenolic condensation product, the rivets are secu ely held in place during the life of the artic e. In fact. the fibrous plates possess such exceptional wearing qualities that the metallic hinge members connecting them will require replacing before the plates have been sulticiently impaired by use to justify disposing of them.
Although I have described. specifically. a plurality of loose-leaf-binder covers which may be constructed in accordance with my invention. it will. be apparent that other covers may be constructed in accordance therewith Without departing from the spirit of my invention. and I desire. therefore, that no limitations shall be imposed except such as are indicated in the appended claims.
I claim as my invention:
1. A book cover comprising superimposed layers of fibrous material, impregnated with a hardened adhesive.
2. A book cover comprising superimposed layers of duck. impregnated with a hardened phenolic condensation product.
3. A book cover comprising a plurality of composite plates of sheet material, impregnated with a hardened phenolic condensation product, and a hinged metallic member secured to the plates.
t. A method of making a book cover that comprises superimposing layers of sheet material impregnated with a phenolic condensation product to form composite plates. subjecting the plates to heat and pressure in a mold to compact the material and to harden the binder. and connecting a plurality of the plates together by riveting hinged metallic members thereto.
A book cover comprising a plurality of composite plates formed of superimposed layers of iibrous sheet material impregnated with a hardened binder and a suitable hingeniember connected to adjacent sides of the composite plates.
6. A book cover comprising a plurality of composite plates Formed of superimposed layers of duck impregnated with a hardened phenolic condensation product and a suitable hinge member connected to adjacent sides of the composite plates.
7. A method of making a book cover that comprises impregnating a plurality of layers of sheet material with a binder. drying the binder by the application of heat, superimposing layers of sheet material to form a plu 'ality of .stacked bodies. subjecting the stacked bodies to further heat and to pres sure to render the binde active and unite the layers of sheet material into a plurality of composite plates. maintaining the application of heat to harden the binder to a substantially insoluble and int'usible state and connecting the plates together b securing a suitable hinge member thereto.
In testimony whereof. I have hereunto subscribcd my name this 27th day of Deon,
JOHN GEORGE MILES.
