My invention relates particularly to pattern making machines for making patteins inenting shoes.

end of the punch with a mallet or hammer, thereby causing the punch to perforate the work in the desired position. As the patterns for the many different styles of' hoes require use of punches of various sizes and shapes, the pattern maker often has a very tedious job. Further, he has to take great care in properly aligning the punches so that the cut-out portions or perforations wil be positioned in the desired position on Even though great care is used in observing each punch used, an entire pattern may be ruined by the use of the wrong sized or shaped punch, or by improper alignment.

It is broadly the object of my invention to provide a pattern machine which will greatly aid in the making of patterns, both from the point of view of the labor involved and in the accuracy with which the work may be done. This 1 accomplish by mounting a series of dies of diuerent size and shape on a movable member, such as a wheel, and by the iurther provision of a work supporting table operable preferably by foot power. Thus, the pattern maker may use both his hands or at least one of them for positioning or holding the work. The wheel is turned; to the proper operating position for the particular die to be and by a simple pressing down on the treadle. the wcrk is carried into engagement with the die.

Ti further my objec to provide a simple gauging device which will be automatic in its operation and which will assist in the accurate positioning of the work.

While the particular type of machine illustrated and described is primarily adapted for work in pattern making, it will also serve a particularly useful purpose in cutting designs in shoe :upper material.

The above and other specific objects to which further reference will be made in the ensuing disclosure 1 accomplish by that certain coin Jination and arrangement of parts of which I have shown a preferred embodiment.

Referring to the drawings:-

Figure 8 is a plan view of the gauge plate.

From the base 1 of the machine frame which I have mounted on a table, an upright portion 2 extends up at the back and has a spindle 3 joure naled in a long boss 4 extending substantially h rizontal with, and at a suitably spaced dis.- tance' from the base, In front, an upright portion 5 journals a vertically slidable spindle 6, which carries the work table 7. The work table, as shown, is adapted for flat work, but different shaped tables or work supports may be employedfor different kinds work. The table may, for example be shaped with clearance at the sides to allow fitted uppers to be draped thereabout. For elevating the work table I have provided a simple treadle actuating mechanism. A lever 8 pivoted at 9 has an end 10 which engages an aperture 11 in the spindle 6. A link 12 indicated in Figure 1 is secured to the long (and of the lever 8 and a treadle 30 may be used to actuate the link 12. In some cases the lever 8 may have a handle at its long end by which the table may be actuated, it being understood that downward pressure on the long end of the lever elevates the table and vice versa.

Detachably mounted on the spindle 3 I have shown the die carrying wheel 13 in the periphcry of which are mounted ornamenting dies 14 f diiierent sizes and shape. A typical example of the variation in sizes and shapes of cutters are illustrated in the pattern strips 140;, having perforations 1 b therein made by dilferent sized and shaped dies. On the outer face of the wheel the several different types of dies are indicated so that the pattern maker can quickly identify the particular die which he wishes to use. In the rear face of the wheel there are a series of apertures 15 and a thumb nut 16 mounted on a pin 1'7 pressed by a spring 18, may be used to cause the engagement of the end 19 or" the pin 17 in th apertures 15, it being understood that each aperture 15 locates one particular die or cutter on the opposite periphery of the wheel in operating position.

The hub 20 oi the wheel 13 has a peripheral groove 21 in which a spring pressed pin 21ais adapted to seat, thereby retaining the hub on the spindle. It also provides a mounting which will allow the operator to quickly remove the wheel and replace it with another wheel in case all the dies which he desires to use in making the pattern cannot be carried on one wheel.

In back of the upright 2 there is a boss 22 which mounts the spindle 23 of a web 24 of backing. The backing is fed through a slot 25 in the upright and then up through a slot 26 in the plate and down through a slot 27 so that area 28 of backing (over a soft metal or fiber plate 28a) is exposed as backing for the cutting dies. The apertures 15 are so arranged that when locked by the pin 17 one of the ornamenting dies will be in direct vertical registry over the area 28 of exposed backing. The backing may be advanced as required by pulling on the end 29 of the backing which extends out under the work supporting plate.

As there are so many mechanical equivalents which might be substituted from the prior art of shoe machinery for the specific mechanical construction which I have illustrated, I have attempted to show only enough to enable one skilled in the art to practice the invention subject to such mechanical equivalent substitutions as he may find desirable.

In Figures 5-8 I have shown a slightly modified type of machine in which I have incorporated a gauging device for assisting in the positioning of work relative to the position in which the work is to be engaged by the ornamenting die. The machine has a base la, upright frame 2:; and a spindle 3a journaled in a boss 4a. The die carrying'wheei 13a is mounted on the spindle 3a and the rnamenting dies 140 are arranged on the wheel in a desired arrangement.

I have further a work table 7a through slots in which a paper web 24a may be moved to provide a desired backing for the ornamenting dies. A link 12a is provided which may be actuated by a treadle 2-0 to cause the work table to be elevated to carry the work into engagement with the desired die.

As one simple means of assisting in the positioning of the work, I have provided a plate 310: which is slidable in guides 32a. Extending from the front of the plate 31 there is a preferably transparent plate 33a having one or more spots or other indicia 34a which will indicate the exact position for the work.

In order to position the work it is placed on the work support and adjusted so that the spot desired to be marked lies directly under the spot on the gauge plate. When the treadle 30 is depressed the gauge plate 33a is moved back clear of the work which will usually be held with the hands at the sides of the work support. The plate 31a is normally held in its forward position with the gauging mark in registry directly under the ornamenting die. This may be accomplished as with a spring 35a.

At one side of the back of the plate 31a there is a boss 36a from which a pin 37a extends. The pin is retained within the slot 38a of a bell crank arm 39a. The opposite end of the bell crank arm is connected with a cable 40a which passes over a pulley 41a and is connected by the link 12a to the treadle so that when the treadle is depressed the link 40a is pulled downwardly rocking the bell crank and causing the pin 37a carrying the plate 31a to be moved back. The gauge plate is thus moved to the rear clear of the work. With the spring construction described, however, the gauge will be moved back as soon as the treadle is released.

I have only shown a simple form of treadle operation in which the parts are shown diagrammatically, it being my object to explain the principle involved which will enable others to provide suitable mechanism which will perform the function of automatically moving the gauge plate back clear of the work during the ornamenting operation.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. A shoe ornamenting machine having a work support with clearance at the sides to enable an operator to hold work at the sides of said support, backing material superposed on said support, a rotatable head having a series of die units mounted thereon, said head rotatable so as to bring a desired die to operative position, a gauge member mounted independently on said support, and a treadle operatively connected to said gauge for moving said gauge away from superposed relation to work held on said support and said treadle having means for moving said support relative to said die to cause said die to pierce work held on said support.
