HEEL AND PROCESS OF,ATTACH|NG THE SAME.

SPECIFICATION forming part of Letters Patent No. 355,027, dated December 28, 1886.

Application filed October 14, 1886. Serial No. 216,203. (No model.)

To all whom it may concern.-

Beit known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heels and Method of Attaching the Same, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

In the manufacture of boots and shoes it is desirable to use in the attaching of the heel blank to the outsole and of the top lift to the surface of the heel-blank cement or glue, for preventing the checking of the heel at these places-namely, the line of union of the heelblank with the sole and of the toplift with the heel. Heretofore this has been done by applying the cement or glue directly to the heelblank or to the top lift immediately before it has been attached to the soles of the boot or shoe, or, in case of the top lift, to the heelblank. This necessitates the use of a brush and glue-pot for holding the glue and applying it, and also a delay inthe work, as it is necessary to apply the glue to the blank or top lift before the operation of nailing can proceed or continue. which arises from the use of the glue at this time, and also to prevent the loss oftime in the nailing operation, I prepare the heel-blanks and top lifts for use by covering the under surface of each with a layer or coating of a glue, which is allowed to dry thereon, so that large numbers of heels and lifts can be prepared in this manner and sold as merchantable articles, and which can be used for heeling. by simply moistening the coating of glue before the blank orlift is attached either by passing over a sponge or other moistening material or a steam or water spray, or by heat or other 1neans,for rapidly moistening the glue or renderingit adhesive. To prepare the heel-blanks and toplifts for sale and use in this way, it is of coursenecessary to use a glue that shall become hard or dry quite quickly and remain hard at ordinary atmospheric temperatures, and I have ascertained that fish glue, or a mixture of fish glue and water, answers well for this purpose.

In the drawings, Figure l is a section of a heel-blank, showingits seat coated with a layer surface.

To overcome this disadvantageof glue which has become hardened. Fig. 2 is a view in section of the heel-blank with a concave seat coated with glue which has become hard. Fig. 3 is a view of the heel-blank represented in Fig. 1 inverted to show thelayer or coating of hardened glue. Fig. 4 is a view of the heel-blank in section, showing the hardened-glue coatings on both the heel-seat and uppersurface. Fig. 5 is a view of the top lift, showing the hardened glue under surface. Fig. 6 is a view of a top lift inverted, showing the hardened-glue surface. Fig. 7 represents in section a heel-blank attached to an outsole, showing the layer or coating of glue between the blank and the outsole. Fig. 8 represents the top lift as secured to an attached heel -blank, showing the layer or coating of glue between them.

A represents the heel-blank. a is its upper a is the surface'termed the seatthatis, the surface which comes in contact with the surface of theoutsole; and it is to thissurface that I applythe coating or surfacing a of glue, which is spread by a'ny suitable means continuously thereon, and is then permitted to dry.

Bis the top lift, and its under surface, I), is similarly covered with a coating or layer of glue, 1); or, instead of coating this under surface of the top ]ift,the heel-blank may have its surface a coated with the layer a of glue or cement. (SeeFig. 4.) I would here say that I do not confine myself to this especial kind of glue mentioned, but may use any that can be reduced quickly to a fluid or semi-fluid or adsubmitting them immediately before using to moisture or heat, and in that condition they are immediately applied to the boot or shoe and nailed or attached. It 'is desirable that the heel-blank should first be applied to the outsole, and itis prepared for use by rendering the glue adhesive either by moisture or by heat, and it is then immediately applied to the surface of the outsole, and while the glue is adhesive is attached thereto under pressure by the attaching nails, which preferably are driven simultaneously. The toplift is then prepared for attachment by moistening or rendering adheel-blank and top lift are made adhesive by he sive the glue coating or layer on its under adhesive condition immediately before the surface, and while the glue is in this condition the top lift is applied to the upper surface of theheel-blank and brought forcibly in contacttherewith by pressure.

It will be seen that this process not only prevents delay in the operation of heel-nailing or heel-attaching, but it also prevents waste of glue, and the disadvantages which come from using it in a fluid condition by a machine, or during the process of attaching the heel, and obviates the necessity for keeping the gluepot and the glue in condition for immediate use, and prevents damage being done to the stock by its use in a fluid condition about the work during the process of heeling.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of thevUnited States- 1. As an improved article of manufacture, a heel-blank having its seat and lower surface, a, or either, covered or coated with a layer of glue or cement which is hard or not adhesive at ordinary temperature, and which is adapted to be made adhesive upon the application of moisture or heat, substantially as described.

2. As an improved article of manufacture, the top lift of a heel, having its under surface coated with a layer of glue or cement which is hard and non-adhesive at ordinary atmospheric temperature, and which. is made adhesive upon the application of moisture or heat, substantially as described.

3. The improved method of attaching heels, consisting, first, in coating the seat of a heelblank with a layer of glue or other adhesive substance, which is permitted to harden before use; second, in reducing said coating to an heel-blank is attached by moisture or heat; third, in immediately attaching the heel-blank to the soles of a boot or shoe while the coating is in this adhesive condition by compression and metallic fastenings driven through the heel into the soles, substantially as described.

4. The improved method of attaching heels, consisting, first, in coating the under surface of a top lift with a layer of glue or other adhesive substance,which is permitted to harden before the top lift is attached; second, in reducing said coating to an adhesive condition immediately before the top lift is attached to the heel-blank by moisture or heat; third, in immediately attaching the top lift to the heelblank while the coating is in this adhesive condition by spanking the top lift upon the heel-blan k with suitable pressure or force, substantially as described. I

5. In the method of attaching heels to the soles of boots and shoes, that step in the process consisting in coating the heel seat and surface a with a layer or coating of glue or other adhesive material, which is permitted to harden before the heel-blank'is attached, then reducing the glue or other adhesive material to an adhesive condition by moisture or heat,then immediately applying the heel-blank to the sole of the boot or shoe and a top lift to the surface a of said heel-blank, and while the glue or cement is in an adhesive condition, substantially as described.
