GEORGE E. lvIUSEBECK, OF MILNAUKEE, WISCONSIN, ASSIGNOE OF ONE-FOURTH 'IO' GEORGE MUSEBECK, ONE-FOURTH TO RICHARD JENTrIING-S, ONE-FUURTH TO CHARLES W. CONAW'AY, AND ONE-FOURTH T WALTER A. WATDSWORTH, ALL 0F LVIILWAUKEE, VJISCONSIN.
VAliLP-FORMING ILIACHINE.
i Application filed July 23, 1919. Serial No. 312,?76.
To all 11 710122416 may comer-22.: e Be it known that l, GEORGE E. MUsnnncK,
a citizen of the United States, and resident of ldilwaukee,-in the county of Milwaukee and State of ll isconsin, have invented new and useful Improvements in Vamp-Form ing l /iiachines of which the following is a description, reference being had to the ac companying drawings, which are a part of this specification.
The invention relates to a vamp-forming machine for shoes and has for its object to produce a vamp having a molded or set ,throat portion which is shaped to substan tially conform to the shape of the last sothut the usual stretching and forming of the vamp over the last with its consequent disadvantages are obviated.
The further object of the invention is to provide a vamp-forming machine in which pressure is gradually applied to the throat portion of the vamp to form it to the desired shape.
A. further object of the invention is to pro vide means for heating the *amp during the forming operation.
The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.
In the drawings Fig. 1 is a side view of the machine embodying the mvention, parts being broken away and parts being shown in section; Fig. 2 is a plan View thereof; Jig. 3
is a section taken on the line 3--3 of Fig. 2.
The numeral 4 designates the frame of the machine having uprights 5 and 6 in which shafts 7 and 8 are journalled. The shaft 7 is the drive shaft and carries a loose pulley 9, a fixed pulley 10 and a fly wheel 11, and
a belt (not shown) is connected to any suitable source of power and when shifted to the pulley 10 rotates the shaft 7.
The shaft 8 is mounted in a swinging or oscillating frame 12 and intermediate the ends thereof. This frame has a slotted rear end 13 provided with guideways 1st in which a two part block 15 is slidahly mounted. The cranked or eccentric portion 16 of the shaft 7 is journalled in said block. The wear on the bearing" block 15 and its frictional engagement with the guideways 14; is adjuster, by bolts 17 which pass through the end 13 of theframe on opposite sides of said block.
A. die 20 has its base removably held'in a pocket formed by side strips 21 and an end strip fixed to the frame t and anend strip has a vamp-forming recess 27 therein of semi-conoidalshape 111 which the curvature" of success velsections gradually increases.
from the forward end 28 to the rear end 29 of said recess, Fig. 3 showing in dotted line a section taken on the line i -4c of Fig. 2.
The outer end 30 of the frame 12 has a vertically disposed bore 31 in which a threaded spindle 32 is adjustably mounted. This spindle has a head 33 at its lower end provided with a bore 34. and a die 3? has a stem 3% seated in said bore 34 and secured to said head by a set screw 37, though it is to be understood that other means may be employed to clamp or secure the die to said spindle.
This die 35 is the counterpart of the die 20 and cooperates therewith to shape the throat portion of the vamp as it is introduced between them.
For accommodating the machine to vamp blanks of different thicknesses of leather the spindle is slidably but non-rotatably adjustable in the frame 12 by means of a spline 38 in said spindle. a screw 39 mounted in the frame and having its inner end slidably engaging the spline 38 to prevent rotation of and the lock nut 11 in threaded engagegagement withthe spindle below the bore 31. With this construction. on a loosening up of the nut 41 the spindle may he raised or lowered to adjust the distance of the die 85 from the die 20 by rotating the nut 40 and the spindle is then locked in adjusted position by tightening up the nut 41 against the frame 12.
In order to heat the vamp during the forming operation I have provided means for heating the movable die 85 by means of a gas jet issuing from a gas supply pipe 12 and directed into heating chamber "-13 in other forms of heating arrangements may be used, as an electric heating coil, if desired.
With the construction above described the frame 12 is preferably oscillated quite rapids ly by rotating the shaft 8 at a fair rate of,
speed. Assaid frame 12 oscillates the dies 35 and20 are moved toward and away from each other, during which time the throat portion of the vamp blank is gradually fed inwardly between the dies and formed into shape to substantially conform to the shape of the last and preferably under the application of heat, as by imparting heat to the blank by heating one of, the dies in the manner above described.
The forming faces of the dies 35 and are preferably so shaped that pressure upon the blank is localized to the throat portion only. T hishas the advantage of preventing vention is not limited to any specific form or arrangement of parts except in so far as such limitations are specified in the claims. What I claim as new and desire to secure by Letters Patentis:
1. In a vamp-forming machine, the combination of a support having. a die mounted thereon, an oscillatory frame carried by said support, means for oscillating said frame,
and a die fixed to said frame and cooperating with said first named die to shape the throat portion of the vamp from a vamp blank during successive oscillations of said frame.
2. In a vamp-forming machine, the combination of a support having a die mounted thereon, an oscillatory frame carried by said support, means for oscillating said frame, a die carried by said frame and cooperating with said first named die to shape the throat portion of the vamp blank, and means for adjusting the spacing of the dies with re spect to each other.
In testimony whereof, I affix my signature.
GEORGE E. MUSEBECK.
