Specification of Letters Patent.

Original application filed November 19, 1913, Serial No. 801,805. Divided and this application filed July 8,

1916. Serial No. 108,157.

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledv in the art to which it appertains to make and use the same.

The present invention relates to an im-- proved machine for preparing insoles for manufacture of shoes.

This application forms a division of my application Serial No. 801,805, filed Novemblcr 19th, 1913, fora process of'making s oes.

It is the practice of the present time in assembling and uniting the various parts which go to make up the complete shoe to rely largely upon the skill and judgment of the operator in positioningthe parts, in proper relation to one another and to the last, and in performing certain operations,

at particular portions of the shoe.

For example, heretofore the operator has commonly been obliged to rely upon his eye to locate the tip line of the upper at the proper angle to the center line of the shoe with the opposite ends at the predetermined distance from the center line of the toe. Also, the points selected by the laster for drawing or stretching the upper over the last and inserting lasting tacks has been largely a matter of individual judgment and practice. The skiving of the welt, the beginning and ending of the inseam, the points at which the welts are butted and the heelseat terminates, generally depend at the present time upon the judgment and skill of,

from the shank to the heel seat so that the welt and outsole appear as one integral part,

not only must the last be properly shapedat and adjacent the breast line, but the welt sewing operation must begin and end and the welt butting operation must be performed at exactly the proper points.

It has been attempted to avoid the imperfections and variations which necessarily exist in shoes as assembled and'united as above described, and to provide afixed and definite mark which will enable the operator, particularly the welt sewing and welt butting operators, to perform their respective operations invariably at the proper point, such a mark being applied tothe channeled face of the insole at'a point corresponding closely to the-breast line of the heel in the finished shoe. This operation has heretofore been performed upon the insole either before or after it was channeled, and always before attachment to the last. The channeling operation, however, as now commonly performed, very generally results in a distortion of the insole, sometimes a lengthening and sometimes a shortening, according to the type ofgmachine employed. Allowance is always made for this variation in length of the insole sufiicient to cover the possible range thereof, the excess of length being.

trimmed or rounded from the heel portion after the insole has been placed upon the last. It is obvious that any mark placed upon such an insole prior to the channeling operation, especially if placed a predetermined distance from' the heel end thereof, will be thrown out of proper position to a greater or less extent by the changes produced in the insole by the channeling operation. The attempt to avoid this difficulty by marking the insoles after channeling has not been successful, as it necessitates gaging :from the toe instead of from the heel, and

furthermore, even if accurately placed after the channeling operation, the distortion and shrinkage which take place in the insoles during the time which elapses between the marking and assembling operations throws the mark out of proper position, and to such varying amounts that little'if any more uniformity ofproduct is obtained than when the operator relies upon his judgment alone in selecting the points for the specified op erations.

h Theprimary object of'the invention is to Patented. Feb. 11, 1919.-

provide an improved machine for preparing insoles in such a manner that the obj ectionable features mentioned above will be overcome.

The invention will be readily understood from an inspection of the accompanying drawings and the following detailed description of the machine illustrated therein, and

" the manner in which it is used to properly vice by a gage'8 arranged'to engage the heel end of the last directly below the attached insole, so that the soles may be accurately "positioned either before or after-the heel seat has been trimmed. Theheel gage is carried upon a horizontally movable slide 10 mounted in the frame of the machine and provided on its under side with a rack 12 which is engaged by apinion 14 secured to a shaft 16. The shaft is provided at its outer end with a-worm wheel '18 engaged by a worm 20 secured to an'adjusting shaft 22. By turning the shaft 22 the heel gage may be adjusted for different sizes of lasts, and the forward end of the'shaft is provided with a dial-'24 for indicating-the size adjustment. The last and attached sole'may be positioned laterally by one of two side gages 26 and 28 mounted upon supports 30 which are adjustably s'ecuredto arms 32, so that the lateral position of the side gages may be varied. The arms 32 are mounted upon horizontal pivots 34, sothat the vertical position of the side gages may be varied as found desirable. The gage 26 is adjusted to properly position the left soles, and the gage 28 to properly position the'right soles of the particular style of solebe'ing operated upon.

The device'for marking the sole, in the construction shown consists of a marker 36 in the form of a vertical platearr a'nged to mark the breast line on the insole when positioned by the-engagement of the last with the heel gage; The lower corners of the marking plate 36 are sharpened to form knife edges arranged to cut the upstanding lip of theinsole, while theintermediate lower edge is adapted to "print or 'emboss a line=across the-body portion of the'insole. The marking through a -vertial sl'ot' in' 'the plate. The

carrier block is secured to the forward end of a lever 42 by a bolt 44 passing through a slot in the lever which is arranged topermit adjustment of the marker longitudinally of thesole. The lever 42 is reciprocated to force the marker against the sole by a cam groove 46 formed in a cam disk 48 and arranged to engage a roll 50 on the lever. Marking material may be applied to the lower edge of the marking plate in case a mark is to be printed upon the sole by a roll or brush 52 mounted in a reservoir or tray 54 which is adapted to be reciprocated across the lower edge of the marking plate. As

- shown, the tray 54 is secured upon the lower end of an arm 56 which is pivoted at its upper end, and the tray is reciprocated by a cam groove 58 formed in the disk 48 and arranged to engage a roll carried by an arm 60, one end of which is pivoted to the tray and the other end of which is slotted to straddle the cam shaft 62.

The cam shaft is driven by a one-revolution clutch indicated at 64 which is controlled by a lever. 66 connected by a link 68 with a treadle 70.

In marking soles by the machines described, the "mark is accurately positioned withrelation to a point on the last, and: will therefore be uniformly and properly located irrespective of any distortion of the sole during the channeling or other opera tion, and will enable the operators to perform their operations upon the shoe uniformly and: accurately without the exercise of the high degree of skill and judgment now required.

"While in the preferred form of the present invention the mark is positioned by gaging directly from the bare last, it is to be understood that the .claims, except where so specifica'lly limited, are not-to be so restricted, as the present invention in its broader aspects" also contemplates gaging indirectly from the last, that is, from some part or portion in definite and predetermined relation to the last, such, for example, as the heel end of the insole after being trimmed,

nor isthe present invention limited, except where so specifically set forth in the claims, to marking the insole at one particular time or stage in the assembling or uniting opera .tions, but may be performed at anytime after the insole is secured to the last and before the outsole is laid.

Having explained the nature and object of the invention, and specifically described one form of machine in which it may be embodied, what is claimed is i 1. A machine for marking insoles on the last, I having, in combination, @means ar- "qra-nged directly to engage the last for posiplate is adjustablysecured to thefro'nt face of a carrier block 38 by a bolt-40 passing tioning "the last and insole, and a marking device for. marking the .insole .at a point predetermined with=relation to the last to guide the operator in subsequent operations upon the shoe, substantially as described.

2. A machine for marking insoles on the last, having, in combination, means arranged directly to engage the back and side of the last for positioning the insole and last longitudinally and laterally, and a marking device for marking the insole at a point predetermined with relation to the last to guide the operator in subsequent operations upon the shoe, substantially as described.

3. A machine for marking insoles on the last, having, in combination, means ar ranged directly to engage one end of the last to position the insole and last longitudinally, and a marking device for marking the insole at a point predetermined with relation to the last to guide the operator in subsequent operations upon the shoe, sub stantially as described.

4. A machine for marln'ng insoles on the last, having, in combination, a back gage to contact directly With the back of the last for positioning the insole and last longitudinally, and a marking device for marking the insole at a point predetermined with relation to the last to guide the operator in subsequent operations upon the shoe, substantially as described.

5. A machine for marking insoles on the last, having, in combination, means for supporting and positioning the last and insole means for marking the surface of the insole, devices for applying marking material to the marking means, and mechanism for relatively actuating the supporting means and the marking means, substantially as described.
