Gttbmeg Patented Sept. 20, 1938 APPARATUS FOR QAPS FOR SHOES Friedrich Gamer-(linger, Zuffenhausen, and Otto" Weber, Stuttgart, Germany Application May 27, 1935, Serial No. 23,636 In Germany May 31, 1934 8 Claims.

This invention relates to apparatus for treatment of material used in forming caps for shoes or the like.

An object of this invention is to provide an ap- 5 paratus which is so constructed that material used in forming caps for shoes may be treated in such a manner that a uniform treatment is had for specified kinds of material.

Another object of this invention is to provide a Iii method of material treatment whereby the material is initially immersed in a treating liquid and maintained in the liquid for a predetermined length of time and then withdrawn from the liquid and given a vapor treatment for a predetermined length of time.

A further object of this invention is to provide apparatus for automatically subjecting material to a softening process so that with a known quality of material any desired quantity may be softened to the desired degree, and each batch of material will have the same degree of softness so that it may be formed or shaped as may be desired.

With the foregoing and other objects in View, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

Referring now to the drawings, and first to Figs. 1 to 4 inclusive, the numeral ill designates generally a housing provided with a lower submersion chamber H and a vapor chamber i2 disposed thereabove. The chamber H isadapted to have a liquid placed therein of suitable character for treatment of the material used in making the caps of shoes.

A channeled guide member i3 shown best in 15 Figures 3 and 5 to 7 extends through the vapor chamber I2 and down into the liquid chamber i I, and a slide M best shown in Figures 4 and 8 to 10 engages this guide it, and is provided at the upper end thereof with a handle or knob i5 by means of which the slide i5 may be pushed downwardly.

The slide it is provided with a rack portion-it and a longitudinally extending recessed portion ll extends downwardly from the lower end of the rack portion is. The slide it is also provided with a longitudinally disposed channel it, and-in this channel a vertically movable rack i9, shown in detail in Figures 11 to 13, is disposed. The upward movement of the rack i9 is limited by a stop 20, and when in its uppermost position the 80 rack it will have the teeth thereof alinging with the teeth i6.

The lower end of the slide M is provided with an outstanding arm M which is slotted as at 22, and this arm 2! terminates in a vertical depending extension 23 provided with a headed pin 24.

A basket or material dipping member, generally designated as 25 has a depending bifurcated arm 26 detachably engaging through the slot 22 and engaging the headed pin 24 so as to hold the bas- 4 lget 25 in outstanding position relative to the slide it as illustrated in Fig. 1. This basket 25 comprises a base or bottom 21 to which are secured a plurality of spaced apart material supporting members 28 which are preferably made from a single piece of wire bent into such a shape to properly support the sheets of. material during the treatment thereof.

The channel i3 is provided adjacent the upper portion thereof with an opening 29, and a gear 30 is mounted on a shaft 3| so that the gear 30 projects through this opening 29 and meshes with the rack it and the rack IS. The gear 30 is connected to a suitable train of gears 32 the purpose of which is to retard rotation of the gear 30, and a clock spring 30', as seen in Figure 14, is associated with the gear 30 to lift the rack l9. The'gear train 32 also effects a retarding of the movement of the slide H for a portion of the movement thereof while the gear 30 is in engagement with the rack l6 formed on the slide.

A slide operating gear-33 mounted on a shaft 34 is opposed to the gear 30 and projects through an opening 35 in theguide l3 and meshes with rack teeth 36 provided on the side of the slide l4 opposite from the teeth 16. These teeth 36 extend for a considerable portion of the length of the slide M. A pulley 3'! is secured to one side of the gear 33, and a flexible member 38 is wound about this pulley or drum-31. A weight 39 is secured to an end of the flexible member 38 and acts to con- I stantly draw the slide i4 and the basket upwardly. A second gear train 40 is connected to the gear 33 and serves as a retarding means for this gear.

The gear 33 is provided with a depth controlling pin 4|, and this pin 4i moves inthe path of a pin 42, seen in Figure 3, mounted on a lever 43 which is pivotally mounted on the shaft 34 exteriorly of the housing ID. A plurality of spaced apart holes 44 are provided in the housing It above the arcuate slot 45, and a spring pressed knob member 46 is carried by the lever or pointer 43 and is adapted to engage in a selected hole 44 so that the pin 42 will permit only a predetermined rotation of the pin 4| and thereby regulate the downward movement of the basket 25.

A scale 41 is mounted on thehousing l0, and the pointer or lever 43 swings across this scale so that the operator of the device may predetermine the depth to which the basket is to be lowered. A second pointer 48 is mounted on the extended end of the shaft 3| and swings across a dial or scale 49 to indicate the position of the sliding rack l9.

A wall 50 is secured beneath the movable basket 25, and when the basket 25 is within the vapor chamber I2 this'wall divides the vapor chamber from the liquid or immersion chamber H (see Fig. 2).

In the use and operation of this device, the sheets of material are placed in the basket 25 between the supports 28, which supports serve as a means to maintain the sheets in spaced apart' relation so that each sheet will be completely immersed or covered by the liquid. The slide 14 is thenpushed downwardly to the limit permitted by the adjustable stop pin 42, and when the slide is in its lowermost position the gear 30 will meshwith the teeth l5.

When the slide is released by the operator, the weight 39 will immediately begin to lift the basket upwardly, and the upward movement of the basket 25 will be retarded by the gear train 40, and also by the gear '38 and the gear train 32, so that the initial upward movement of the slide I4 will be relatively slow, and this movement will obtain until the gear 30 rides off of the teeth It, whereupon the slide I 4 will be retarded by only thegear train 40 and will thus move upwardlv at a faster rate. The gear 30 is constantly in mesh with the sliding gear or rack I3, and when the slide l4 moves independent of the gear 30 the rack [9 will be caused to move upwardly at a slower rate than the slide l4 and so willbe relatively lowered in the guide groove l8 but gradually moves up in the slide l4 and enl2 the movement thereof will stop, but the timed movement of the sliding rack l9 will continue until this rack strikes the stop 20. At this time the pointer 48 will indicate this fact on thedial 49 so that the operator of the device will know that the time of the vapor treatment has expired. Each downward movement of the slide i4 will wind the spring associated with the gear 30 in addition to winding up theweight 39 so that it is only necessary for the operator-to set the pointer 43 for the desired immersion, and then watch the pointer 48 so as to see when the time of vapor treatment has expired, it being understood that the dial 49 is provided with suitable indicia to show the immersion period and also with suitable indicia to show the vapor period, and if desired a suitable signal may be connected to this pointer 48.
