SHOE-FILLING MACHINE.

Specification of Letters Patent.

Fatentea Feb. 3, 1920.

Application iiled October 11, 1916. Serial No. 125,099.

cost, to fill shoes by wholly automaticA power machine and accordingly my present invention aims to come as near to an automatic machine as is practicable. To this end I provide means which is partly antomatic and partly dependent upon the skill of the operator. The problem of filling shoes with the peculiar filler mentioned (which is exceedingly difiicult to manage) requires not merely the simple depositing' ofV the filler into a shoe bottom cavity, but the initial sticking of the filler in the cavity so that it will stay where placed and then,

when the filler has chilled or partially setV upon contact with the cold and usually damp leather, a final condensing, spreading, leveling and preferably eXtra-heating and all this filling operation must take place with extreme rapidity, in fact I estimate that to attain a marked success, my machine must enable the operator to accomplish all these filling movements in'about two seconds as an average throughout the day, (aside from the two or three secondsadditional required to get the shoe from the rack and' replace it on the rack). Skilled operators working entirely by hand (aidedV by the Besto machine of Patent 808,227) require only about eight seconds per shoe, of which between two and three seconds are consumed in movements to and from the shoe rack leaving only about five or sixseconds for the hand filling operations. In attaining the desired result, I provide a filling machine having asupply chamber in -one portion and a very small, slender or narrow snout or nose extending forwardly and downwardly to receive a shoe-bottom against its lower end in an oblique plane, said nose being suflciently small so that the operator vcan easily see around it and so that the nose will not interfere with the operators easy view of the shoe bottom as it is being filled and manipulated against the extremity of this nose. Vithin the nose is a plunger-like filler ejector which operates rapidly to remove small pcrtions of filler from the mass of filler and forcibly stamp or propel these small portions onto the shoe bottom,preferably with suflicient force to compress them somewhat and stick them thereon. This ejector has an intermittent motion under the control of the shoe or the operator; and a continuously operating feed device serves to maintain an abundance of filler ready at all times to be ejected. Immediately adjacent the ejector at the delivery orifice of the machine is a condensing and leveling device which is .preferably` heating and is so positioned that the operator can instantly perform the leveling, spreading and condensing operation on the ejected and deposited filler while the shoe is still in place against thenose of the machine.

In the accompanying drawings in which I have shown the preferred embodiments of the invention, Figure l is a top plan view of the machine and Fig. 2 kis a view thereof in side elevation partly broken away and sectioned.

From the lower end of the upper hopper of the filler supply chamber 1 extends a A small, narrow nose or extension 2, both being preferably jacketed for steam and hot water Vin order to maintain the filler in a uniform, plastic, melted condition. Mounted to reciprocate in the front portion of the vnose isa plunger-like ejector 3 whoselower guided` on the shaft 6 which vpasses through a slotV 7 in said upper end and the latter is provided with a laterally extending friction roll 8 held by a spring 9 in engagement with a lifting cam 10 fast onsaid shaft, driven n by a pulley V11 and any suitable clutch mechanisin, a magnetic :clutch 12- being herein indicated, under the control of arcontact maker 13 F1105@ lower'. @ed 14 rronetsrret ioo erably into the path of the shoe bottom and also preferably laterally at 15 in position to-be raised by the finger or thumb of the hand which holds the shoe. This Contact maker when moved upwardly engages a. contact 16 to complete the circuit for energizing a magnetic clutch, which being well known, I will not describe in further detail. At one side of the ejector 1 provide a feed device for maintaining a continuous supply of filler in constant readiness to be ejected at the ejecting end of the plunger 3. Any suitable feeding device may be employed, but T have preferred to show a sprocket feed chain 17 mounted on sprocket Wheels 18, 19 as best shown in Fig. 2. The drive sprocket 19 has its shaft 2O provided with a pulley 21 andbelt 22 for driving the pulley 11 and is itself shown as driven by a pulley 23. Immediately adjacent the orifice 4 and just below the same at the end of the nose or eX- tension 2 in position to engage the shoe bottom as the latter is filled, 1 provide a flat, smooth, curved surface 2st preferably steam heated at 25 and preferably projecting at one side 26 of the machine. This member 24 constitutes a leveling and condensing means and is made wider than the nose simply in order that the operator may press the shoe bottom against the same more carelessly than he would if restricted to the narrow width of the nose. The transverse lower end of the ejector is small, an inch or less being sufficient for my purpose, although for the larger sizes of shoes a slightly larger ejector may be employed. However, it is not intended to have the ejector span the shoe bottom nor a considerable portion thereof, but rather to depend upon the rapid repetition of its ejecting movements to secure the delivery of the required Yamount of filler for a shoe bottom.

In operation, the operator presses the toe end of a shoe bottom against the end of the nose thereby simultaneously engaging and lifting the contact maker (or other tripping device) which instantly clutches the cam shaft 6 to the driving pulley 11 and by means of the cam 100 roll 8 and spring 9 instantly reciprocates the plunger 3 and the latter deposits each time a spot or small button-like portion of filler and as these portions of filler are rapidly moved onto the Ishoe bottom, the operator with corresponding rapidity moves the shoe bottom to receive them. His skill enables the operator to thus plaster the entire shoe bottom full of ller by a single sweep or Zigzagging forward movement of theshoe. The filler depositing end of the plunger, but iseslightly V stuck 'onto the grained surface ofthe shoe bottom :by the pressure of the plunger. The plunger retreats each time to Va point 27 sufiiciently above the orifice to permit fresh filler to be moved instantly into place beneath the plunger and into the orifice to be ejected. The feeding mechanism operates continuously and maintains a body of filler at the lower end of the nose-chamber always ready to get in place at the orifice whenever the plunger 3 rises. As soon as the shoe bottom has thus received a proper amount of roughly or crudely spread filler, the operator lowers the heel end thereof so as to disconnect the plunger actuating clutch 12 and, at the same time, so as to bring the shoe bottom into better contact with the leveler and condenser 24; over which the operator then quickly moves the shoe bottom in such manner as may be required in order to spread and condense the filler properly into the shoe bottom cavity so as to fill all the crevices or corners and the entire space of the area desired to be filled. If he observes any spot not properly lled, he simply strikes that portion of the shoe bottom against the orifice thereby simultaneously starting the ejector and receiving a dab of filler therefrom.

My object is to provide'this finger-like or nose-like tool against which theoperator simply presses the shoe bottom with proper skill and the machine does the rest.

I aim to provide a machine or tool to move rapidly and perform certain operations now slowly performed by the hand operator. The leveling of the shoe bottom will be a brief operation when the operator' has attained proficiency in accurately spotting or placing the little pats or buttons of filler in the shoe bottom cavity as they are discharged with great rapidity by the ejector. It is intended that the skill of the operator, supplemented by the speed of the machine, shall result in enabling the operator rapidly and accurately to place and stick just enough filler, and no more, in the shoe bottom cavity to make a good bottom. This makes the subsequent heating and leveling of the bottom an operation that can be accomplished with a very slight movement of the shoe under the heating and leveling device. My object is to provide a. tool with which the operator can, with` one short, rapid zig-Zag movement fill the shoe bottom cavity and with another movement level the bottom so that by reducing the motions of the operator and making most of the operations power-applied, the operator is thereby able to fill twice as many shoes with the same or fewer motions than he now uses in the operation of the Besto machine 808,227 (it being my opinion that this rate of speed and saving over the present hand method will be to supplant the said hand method as a commercial proposition).
