To all-whom it may concer/ri:l

Be it knownthat I, WILHELM A:- ZIoKER- MAN, a citizen of the United States, residing at 8 Berwick Park, Boston, county of Suffolk,

and State of Massachusetts, have invented' an Improvement in Methods ofA AFilling Insoles, of which the following description, in connection with' theV accompanying drawings, is a specication,v like lettersA on the drawin representing like parts. c

This invention pertains to a method of applyin cementitious filling material to'boot land s oe soles, especially insolesgland .com

prises variousfeatures of procedure explained in .the course; of the following description and defined in'the'annexed claims. .u

The character of theinvention-may be best understood by reference to the accompanying drawings, whichshow.. an illustrative insQ e.- filling machine Y whereby an' exemplary method embodying this .invention `may be conveniently practiced Figure 1 is aside elevation of a machine intended more particularly fr applying filling material to insoles of shoes and Fig. 2 is y a detail perspective of'apait of said machine.

. While tbe invention may be described convenientlyT in connection with the machine in the drawingsit is by n0 -means essentially limited to the specific details of operation, nor to the specific functions involved in said machine. 1

The illustrative machine has insole presenting means supplied by a traveling chain conveyer 1,- appropriately mounted on sprocket wheels and driven from a master shaft 2. In the preferred operation of the illustrative machine, the conveyer travels in the direc# tion of an arrow 3.

' The insole presenting means is exemlified by shoes carrying trays 4-4, removably mounted on steps 5 and 6. Any practicable number of trays 4 may be used, and each tray may be arranged to accommodate any practicable number of shoes. The racks 4 4 may travel with the conveyer 1, and during this travel, in the operation of thisspecic machine, each shoe is first provided with an application of cement from a cement reservoir 10; and thereafter with an application of dry filling material, such, for example, as

ground cork, sawdust or the like delivered.

from a hopper11.

I n the cement tank 10, a steam coil 12 maintains thecement in proper fluid condition. The cement Aescapes from the tank through one or more outlets 14 in the bottom of a chest 16. 'Vertically' movable plungers 17 are reciprocated to open and close the 'outlets 14. .While the specific machine provides for automatic operation of the plungers 17, the latter may be manually operated,

Wherefore itis unnecessary to describe them further.

The cement issuing from an outlet 14 is received upon a cement distributer 18 (see Fig. l2), l and being separated into three streams, one traversing the slot in the dis tributer 18 and the other 'two fiowing along the-diverging faces thereof, is distributed to different parts ,of the insole. with` the cement on the insole continues to `move (see arrow 3), a s' readerorscra er 20 smooths the cement an ap lies it to al parts of the insole. Proceeding 'urther, the insole arrives beneath the filling material hopper. 1 1. The latter has an outlet'22 closed by a sliding gate,- Wh-ich may be manipulated in any c onvenient manner. opened as the advance end -of the cemented insole takes position beneath it; and the gate remains o en during continued travel of the shoe unti the filling material has been delivered along the "desired length. In this manner, a dry filling material maybe delivered progressively along the insole to its freshly cemented surface; andthe filling ma! terial so delivered may com letely cover all cemented parts of the inso e. Progressing further, the advance end of the insole engages with a spring pressed roller24, which presses down or lays the filler firmly against the cemented insole. .This pressing action of the roller 24 maytake place during continued mpvement of the shoe, so. that the filling material may be progressively pressed into place. Also, any superfluous (ry material may be pushed rearwardly on the shoe by the roller 24. After departing from the roller 24, the insole passes beneath a discarding device, such as a brush 25, by which superfluous filling material is removed from the insole. The above described cycle of operations is preferably repeated for each shoe or each tray of shoes; an d various operations in the cycle may take place simultaneously on different shoes.

The illustrative method described as prac ticed by the machine in the drawings may be conveniently summarized as follows :-Ce-

As the shoe Preferably, the gate 22 is sawdust or the like, hereinbefore suggested' ment is suitably applied to the insole or other' Work; the dry filling material or the like is applied thereto progressively, is laid thereagainst progressively so as to cover the cemented parts; and finally su eriiuous, nonadhering material is discarde.

Describing the illustrative method more in detail, the specific apparatus shown in the drawings may perform several characteristic operations. For example, the ground cork,

as a suitable filling material, is inherently elastic when in its dry, granular state; and this, u on being deposited on the sole and passed eneath the roller 24, is firmly pressed againstvthe sole face, thereby compacting it and, it may be, actually compressing it, so as `to force the particles of filler closely together and to express air from the mass of'liller. When the filler thus compressed departs from beneath the roller 24 and is released from the pressure thereof the bodyv of filler, by its elasticity, expands slightly and thereby, tlirougha species of suction, the cement .is drawn from the sole face into the interstices of the filler. This may have the ellfect of a sponge-like action, 'attributable to the elasticity of the filler, whiclr may be effective to draw the cement to a higher point in the body of the liller than would be obtained by mere capillarity of inflexible or inelastic particles. At the same time, the compacting of the surface of a 'comparatively thick mass of filler causesthe particles at the surface to cohere Vlirmly witho ut permitting or req uiringlthe invention is not limited to the specific imethod just summarized, nor is it to be limited to the particular functions performed by lfiller to cause parts thereof to-be directly incorporated Wththe cement and other parts to cohere, the Whole presenting a surface substantially dry and free from cement.

r2. Amethod of iilling insoleswhieheonsists in applying cement to'the sole-face Within its lip; introducing dry elastic filler to the cemented area; compacting and compressing the dry elastic filler. against the cement, levcling it to substantially the depth ofthe lip and removing superlluous iiller.

3. A method of filling insoles Which consists in supplying cement to the sole-face; covering the sole-f .ce with an excess of elastic filler; compacting thesame to cause it to cohere and adhere 'to the cement; and discarding any filler which remains free.

44. A4 method of filling insoles which consists in supplyingI cement to the sole-face; supplyingr elastic dry `liller to the cemented area; compressing the elastic dry Jfiller against the cement to express air therefrom; and then releasing the elastic 'filler from compression, permitting it to expand and draw cement by suction into interstices of the filler.

5. A method of Vfilling,` ins'oles which` consists in supplying cement to the sole-face supplying dry elastic iiller to the cemented area, compressing the elastic 'filler against the cemented4 area; and releasing` it from compression, permitting' it to expand and admit cement into interstices.

In testimony whereof, l have signed my name to this specification, in the presence of two subscribing Witnesses.
