SHOE-BOTTOZM-FILLING APPARATUS.
Application 'filed March 12, 1925. Serial No. 14,948. I I
To all whom it may concern:
Be it known that we,LoUIs L. BENTLEY,
and JOHN W. SLoAN, both citizens. of the United States, residing, respectively, at Beaver Falls and New Brighton, county of Beaver, and State of Pennsylvania, have inwhen heated suificiently to render it freely plastic or semifluid. This material usually consists of a mixture of comminuted cork, gutta-percha, resin and other materials and is furnished in so-called loaves convenient to handle.
The object of the present invention is to provide an improved apparatus for melting these so-called loaves and applying the semi;
' fluidfiller material to the shoe bottom cavities. One feature of the invention is the provision of a heating chamber having a grid for supporting the loaves and having a plurality of sheet metal partitions dividing the heating chamber into a number of compartments whereby the heat is more uniformly distributed to all parts of the loaves. Another feature of the invention is the provision of a vent for the steam jacket surrounding the heating chamber whereby the temperature in the heating chamber will be prevented from rising substantially higher than 212 F. Still another feature of theinvention is the provision of a revolving paddle in the dip-pot for drawing the melted filler material to the front of the dip-pot, this revolving paddle acting as a sort of closure for the opening in the front wall of the heating chamber, thereby reducing heat losses and facilitating keeping the material in the rear portion of the dip-pot in a semifluid condition.
A preferred embodiment of our invention tom and side plates.
is illustrated in the accompanying drawings, 1n which I Figures 1 and 2 are respectively a front elevation and a side elevation. of the apparatus; Y I I Figure 3 is a plan view of the apparatus with the cover of the heating chamber removed; a
Figure 4 is a longitudinal sectional View on the line IVIV of Figure 3; and
Flgure 5 is a transverse section on the line V V of Figure 4.
Referring to the illustrated embodiment of the invention, 2 designates the dip-pot which is supported by metal legs3 in the form of angles and connected by suitable braces 4. The dip-pot may be constructed of brick work supported in sheet iron bot- The bottom of the filler-receiving cavity 5 of the apparatus is formed by a hot water jacket 6'the walls of which are constructed preferably of sheet copper. v j
V Extending above the rear portion of the dip-pot is the heating chamber 7, the walls 8 of which may be formedof cork. This chamber has. a cover 9 of cork board with a sheet iron bottom plate lO. This cover may be hinged at its rear edge as at 11. The cork walls 8 may have an outer facing 12 of sheet iron. A steam jacket 18 surrounds the heating chamber and forms a continuation of the hot water jacket 6. At the bottom of the heating chamber is a grid, consisting of small bars 14, for supporting the loaves of filler material. This chamber is divided into a number of compartments each conveniently of a size to accommodate one loaf, by transverse sheet metal partitions 15, preferably of copper.
Journaled in bearings 16 attached to the front wall of the heating chamber is a rod 17 having a handle 18 at its upper end and havin a collar 19 en a in the lower bear- 0 b D b ing 16. This rod has a paddle 20 mounted on its lower end, the purpose of which will be hereinafter explained.
At one side of the dip-pot is a water fill:
ing pipe 21 communicating with the water jacket 6 whereby the proper amount of water can be supplied to the jacket. At the opposite side of the dip-pot there is a water gauge 22 also communicating with the water jacket whereby the level of the water in the jacket can be observed.
The water in the water jacket can be heated by any suitable means, such as electric resistance elements. The means that we have shown however consists of a steam coil 23 within the water jacket. A steam pipe 24 constitutes a bearing for a roll 25 arranged above the front portion of the cavity 5, this roll being employed to spread and compact the filler material in the shoe bottom cavity and being maintained in a heated condition by the steam which passes through the pipe. The steam is supplied to the pipe 24 by a pipe 26. The pipe 24 passes along the front and one side of the heating chamber, then along the back thereof and communicates with one end of the steam coil at 27. The other end of the steam coil communicates with a steam outlet 28. At one-side of the heating chamber is a knife or spatula heater 29 heated by the pipe 24. The supply of steam is controlled by a valve 30. Communicating with the upper portion of the steam jacket 13 is a vent pipe 31.
The operation of the apparatus is as follows: The loaves are placed in the heating chamber 7 on top of the grid 14. The steam is turned on and as the water in the water jacket 6 begins to boil, steam rises -lVl1ile we have shown and into the steam jacket 13 and heats the heating chamber, The loaves are slowly melted and the semifluid filler material flows down into the rear portion of the cavity 5. The vent 31 prevents an accumulation of pressure inthe steam jacket such as to. cause a rise in temperature substantially above 212 F. and hence danger of overheating or burning the filler material is avoided. The paddle 20 in the normal position shown in the drawings forms a partition for the cavity 5, and a sort of closure for the opening between the lower edge of the front wall of the heating chamber and the bottom of the cavity 5. Thus the bulk of the melted filler material is normally maintained in the rear portion of the cavity 5 under the heating chamber. WVhen it is desired to fill the bottom cavity of a shoe, the paddle is revolved to draw some of the melted filler material into the front portion of the cavity 5, where upon it can be applied to the bottom cavity by means of a spatula.
described a preferred form of our invention it will be understood that the invention is not limited to its illustrated embodiment but may be otherwise embodied within the scope of the appended claims.
