A DHFISIVE COMPOSITION.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed larch 20.1907 Serial No. 363.482.

; lowing is a specification.

My invention has relation to adhesive compositions; and it contemplates the provision of an economical adhesive composition ossessed of a high degree ofelastic bin ing 4 pro apse of a short period power and calculated to save in the production of work by ex editiously drying, and one which by reason 0 its nature is ada ted to be deposited in sufficient quantity or strong binding on the surface of a part that is to be connected to another part and yet is not liable to enetrate to an undue extent into the material of the said part.

My composition consists of glue made according to the ordinary, well known formula orany other formula consonant with the purose of my invention, and finely subdivided bers, referabl fibers from paper and cellulose, t ough ot er fibers possessed of capillary characteristics and insoluble in water, such for instance as fibers from leather, linen, wool, cotton, silk, hair, wood, and analogous materials, may be employed without involving departure from the scope of my invention as defined in the claims appended.

In the preferable practice of my invention, the finely subdivided fibers are mixed with glue prepared in the usual Waybut not dried and not quite finished; the proportion of the fibers to theglue depending on the character of the parts to be connected. The roper ortion of fibers is best determined y a plyinga thin layer of glue to the surface of t e art to be connected, and observing after the are saturated, if there is an adequate layer of fibers on the glued surface'i. 6,, a layer sufficient to assure the proper binding of the part to another part. This is particularly true whefileather, paperand soft woods are to .be lue g The fibers mixed with the glue take up by capillary attraction the moisture of the glue and give off such moisture to the atmosphere or in other words serve as a siccative; and it will also be manifest that the fibers render the adhesive mixturetough and elastic, that they assure the surfaces of the parts to be conwhen all of the fibers nect ed being jagged and calculated to closely fit each other, and that by settling on the sur-;

face of the glue they contribute materially to the strong and durable cohesion of the parts.

This latter is especially characteristic of my composition when the same is employed in the connection of parts of wood, leather and paper.

t will be gathered from the foregoing that sition is advantageous, because the my com 'le enhancing the binding strength fibers, w

of the compositionrender the same much cheaper than a corres onding quantity ofprevent gluealone; also, that t e fibers, by ing penetration of an undue quantity of glue into the material or materials of the parts connected effect a saving of glue, and this while expediting drying of the glue and composition as a whole, and in that way contributin to the cheapness of the work roduced.

W enchea production of work -1S sought, I use paper fi ers because of the facility and cheapness with which the same may be produced.

While I have designated glue as the preferable adhesive material my invention consists broadly in the combination of fiber substantially as specified with any suitable adhesive substance as for instancestarch paste, flour paste, dextrin, albumen, shoemakers pulp, etc.

Havin described my invention, what I claim an desire to secure by Letters Patent, 182- 1. 'An adhesive composition capable of adhering to the surface of a part that is to be connected to another part' and comprising an adhesive substance, and fibrous material commingled with the adhesive substance for taking up moisture from the same and giving off such moisture to the atmosphere to accelerate drying of the composition; the proporof fibers suflicient for the'proper binding of the part to another part.

3. adhesive composition capable of ad- 'hering to the'surface of a part that is to be connected to another part and comprising glue and a fibrous material combined therewith; the proportions ing such as to assure the provision on the glue of a layer of fibers sufficient for the proper binding of the part to another part.

4. An adhes ve composition capable of adhering to the surface of a part that is to be connected to another part and comprising an adhesive substance and fibrous material commingled with the adhesive substance for taking up moisture from the same and giving off such moisture to the atmosphere to accelerate drying of the composition; the proportion of adhesive substance being suflicient to saturate all of the fibers of the fibrous material and such as to assure the provision on the adhesive substance of a layer of fibers sufficient of the ingredients be? for theproper binding of the part to another art. p 5. An adhesive composition capable of adhering to the surface of the part that is to be connected to another part and com rising lue and fibrous material possessed oFcapilarity and insolubility, commingled with the glue; the pro ortion of glue being sufficient to saturate all the fibers of the fibrous material and such as to assurethe provision on the glue of a layer of fibers sufiicient for the proper binding of the part to another part.

In testimony whereof I afiix my signature in presence of two witnesses.
