and lay it fiat on the inner surface of the shoe.

Prior to my invention various devices have been produced for raising the'lip and settingit in a predetermined position, one of which comprises a reciprocating hammer which is arranged to strike the lip its base and upset it, so'that it will beheld n a verticalor slightly bent-over' pos'ition. This method is objectionable for the reason that, asthe blow of the hammeris directed at the base of the lip, it frequently tears the 11p from the sole or weakens the portion of the leather which connects it to the sole and places an objectionable strain thereon.

In another type of machine more nearly similar to ,the machine which constitutedthe subject-matter of my invention, in which the purpose is not only to raise the lip, but

to bend it back and layit flat on the surface of the sole, a hammer is provided with means for causing it' tostrike a vertical blow, on

the lip after it has been raised by the plow and bent back to or beyond the vertical position'. With this type of machine the lip is frequently struck. directly on its edge,

while in a vertical position, causing it to be beaten down without being bent over; This is especially liable to occur when the lip is short and thick.' V

Difficulty has also frequently been encountered in setting the lip in bent-Wei position when it is short and thick, as it tends strongly to returnto its natural position. 7

The object ofmy invention 1s to provide a machine 0f the above character which is adapted to raise the lip and then turn it over and .down onto the surface of the sole, so

that it will be set in this position without liability of having the lip-setting means beat down the lip without having it turned over.

furtherobject is to providea machine which shall be of simple and durable construction, sothat it is unlikely to get out of order, and may be manufactured at small expense.

I accomplish these objects by the means shown in the accompanying drawing, in which, V V Figure 1 is a side elevation of a machine made according to my invention.

Fig. 2 is a plan view thereof, and

Figs; 3 and 4c are detail views illustrating {he manner of turning over and setting the .lP- Figs. 5 and 6 are detail sectional views of the hammer and its holder.

In the drawing 1 indicates the base of the machine having a bracket 2 thereon in which the main shaft 3, which is driven from a suitable source of power, is mounted. Said shaft has aneccentric 4 thereon on which a block 5 is mounted, said block being an ranged to slide between the arms of a lever 6 which is mounted to oscillate on a shaft 7 in a bracket 2, so that as said shaft 3 is driven said lever will be oscillated.

The shaft 3 is also provided with a worm 9 which isarranged to engage a worm gear 10 mounted on an inclined shaft 11, said shaft being journaled in the base of the machine and also in a bracket 12, secured to the front side thereof. A feed wheel 13 is mounted on the upper end of said shaft, said feed wheel being adapted to bear on the edge portion of the sole from which the lip has been out. A vertically yielding shaft 14 is mounted to rotate vertically in the bracket 12, and is provided with a circular feed table 15 on the upper end thereof, and

suitable treadle mechanism, not shown, for drawing down'the table is provided. A gear 16 is mounted on the shaft 11 and arranged in mesh with the gear 17 on the shaft 14, so

that the sole-engaging portions of the feed wheel and table are driven at the same sur-' face speed. I

According to my invention I provide an arm 18 which is mounted on pivot 19 ad jacent the base of the machine, at a considerable distance beneath the level of table ,15, and also some distance in the rear thereof, and extends upwardly from said pivot to points above the level of the table. Said arm 18 is provided with a socket 18 which extends at right angles therefrom at its upper end, and a depending hammer holder 20 is adjustably mounted in said socket and is adapted to be secured therein by a clamping screw 21.

A hammer 22, which is square in crosssection, is reciprocally mounted in a correspondingly shaped recess in said holder 20, in a position nearly parallel to the arm 18 and a screw 220 extends through said holder and is threaded in the upper end of the hammer, the head of said screw normally resting on the upper end of the holder. A spring finger 23 is secured on the lever 18 and rests on the head of the screw 220 and normally holds the same against the holder.

The lower end of the hammer 22 is provided with an engaging face 22, which is obliquely inclined with relation thereto, as shown in Figs. 3, i and 5. A link 24 is 0011- nected to the upper end of the arm 6 and to the upper end of the arm 18, so that as the shaft 3 is rotated, said arm 18 will be occillated.

A plow 25 is mounted on brackets at one side of the hammer 22, in position to pass between the surface of the sole and the lip, so as to raise it in the usual manner.

A lip depressing finger 26 is also rigidly secured onbracket 27 at the opposite side of the hammer 22 and in position to bear on the lip, afterit has been turned over, as hereinafter described.

In operation, the table is rotated in the direction of the arrow in Fig. 2, and the sole is passed between the table and the feedwheel 13 in the usual manner.

The arm 18 is oscillated, and, as the center about which it swings is located at a considerable distance below the level of the table 15, and in the rear thereof, the hammer 22, which is held so that it depends directly over the edge portion of the table in a nearly vertical position with relation thereto, will be carried laterally, or in a direction transversely thereof, and with its face nearly parallel to the surface of the table, and, at the same time also longitudinally downward toward the table. The path of movement of the hammer is such that its face 22 either is caused to engage the edge of the lip which has previously been raised by the plow, or its front side is caused to engage the side of the lip closely adjacent its edge and to bend it over and press it, or hammer it down, so that it lies flat on the inner surface of the sole, as shown in Figs. 3 and 4-. llhat is, the hammer strikes down on the lip with what may be termed a drawing blow. The face 22 of the hammer is made slightly oblique to the sides thereof, so that said face will be held flat with the sole at the end of its strike, and will also have a drawing or pushing effect until it reaches that point. As the hammer is adapted to yield upward, slightly, against the action of the spring 23, and as-the table 15 is also adapted to yield downwardly, variations in thickness of soles and of the lip are provided for.

"Whether the hammer first strikes directly on the upturned edge of the lip with its face 22, or whether its side first strikes the under side of the lip and then pushes it over, so that the lip is then engaged by its face 22, depends on whether the lip is short or long, and on the vertical adjustment of the hammer by screw 220.

While the hammer will press the lip down from the vertical position of F i 3 to the position of Fig. i, the lip will not always be fully set in this position, and for this reason I preferably provide the finger 26 which bears firmly on the lip after it is turned down, and as the sole is fed beneath it, and materially assists in setting the lip in the turned down position.

While the above described construction is a preferable form of my invention, various other forms of mechanism may be produced which will cause the combined downward and forward movement of the hammer, above described to take place.

I claim V 1. A lip-turning machine comprising a sole support, a plow for raising the lip, a hammer having a face at its end, and means to hold said hammer with its face approximately parallel to the face of said support and to cause simultaneous transverse and longitudinal movements thereof, so that its said face is carried over and toward the surface of the sole supported thereon, to bend back the lip and beat it down toward the sole.
