METHOD OF PREPARING BLANKS FOR SHOE-PEGS.

Specification of Letters Patent No. 19,282, dated February 2, 1858.

To all wiom t may concern.'

Be it known that I, B. F. STURTEVANT, of Boston, in. the county of Suffolk and State of Massachusetts, have invented a new Process of Manufacturing Blanks for Pegs to be Used in Shoe-Pegging Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figures l, 2, 3, 4 and 5 illustrate my process and will be referred to hereafter.

Machines for pegging boots and shoes require to be furnished with pegs in long strips or blanks which are fed forward and cut up into pegs by the machine as the work proceeds. It is evident that such blanks or strips should be made of perfectly straight grained wood and must be entirely free from knots and other imperfections. Heretofore great inconvenience has been experienced by the operators of these machines, on account of the defective and knotty state of the wood from which the pegs are formed and this difliculty has thus far stood in the way of the introduction of these machines into general use.

On account of the above difficulty those woods that would make the best pegs, such as hickory, cherry and maple are in general totally unlitted for the purpose by the twisted and crooked manner in which they grow, and an inferior wood (white birch) is therefore chosen for the purpose, owing to its straight grain and comparative freedom from knots. Even this wood however is hardly less objectionable for machine use than the others, as wherever the strips or blanks from which the pegs'are to be cut cross the heart or a knot, a portion requires to be discarded and this involves the necessity of culling over the pegs before they are used and results in a considerable loss not only of material but of time. In addition to which the blanks are in short pieces and require to be frequently furnished to the machine by hand.

To obviate all these inconveniences and to furnish blanks entirely free from imperfection and in large quantities to the pegging machines is the object of my invention which I will now proceed to describe.

The lumber employed is first sawed into planks of 2 inches thickness or thereabout; it is then sawed into strips A Fig. l of which one is seen detached in Fig. 2. All knots and other imperfections are then cut out and discarded and the clear strips are glued together as seen in Fig. 3 forming a new plank of entirely clear stuff. These composite planks are then sawed into blocks the thickness of which is equal to the length of the intended pegs, the section passing through the lines a, a of Fig. S- the blocks thus formed are then glued together so as to form the large blocks (Figi 4) from which lthe blanks are sawed off upon the lines c, c. The blanks thus'formed are now assembled in packages (Fig. 5) and are held together by narrow bands f of adhesive paper which attaches itself to opposite sides of each strip, which arrangement enables the operator to place a package of blanks in the machine at one time, the blanks being torn off one by one in succession, by a suitable feed, the adhesive paper holding all the remaining blanks in a body, so that at any time when it becomes necessary to remove them from the machine it may be done by simply taking out the balance of the package which still remains bound together by its adhesive bands.

The above described process of manufacturing blanks for shoe pegging machines and uniting them in packages by bands of thin adhesive paper offers the following advantagesz-lst, the pegs may be made of the toughest and most refractory woods as hickory maple or cherry, such pegs making far better work than those of softer wood, which are easily mashed down when driven; 2nd, the blanks may be freed from all imperfections, knots, and heart, by which all subsequent loss to the manufacturer is avoided as well as the labor of culling them over before putting them into the machine; 3rd, the blanks may be made of a uniform and unvarying length, a great convenience so far as relates to transportation and handling and also as regards their adaptation to particular machines; 4th, seasoned lumber may be employed and the necessity for drying and the consequent warping of the peg is avoided; 5th, the blanks may be placed in the machine in a package, and may at any time be removed therefrom without trouble, the adhesive bands holding those remaining together as before stated.

It should be mentioned that pegs for pegging machines do not require to be pointed.

lOO

What I claim as my invention and desire to secure by Letters Patent isl. The Within described process of making blanks for shoe pegs by sawing and 5 glueing up the material in the manner substantially as set forth for the purpose specied.

2. I claim the method herein described of securing the blanks in packages by means of bands of adhesive paper or their equivalent, 10 whereby the blanks may be placed in the machine and-removed therefrom in bundles as set forth.
