To allwlwmz't may concern."

Be itknown that I, ARTHUR BATEs,a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Upper- Shaping Machines, of which the following description, in connection with the acco1n-- panying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for shaping the uppers of shoes and more particularly to machines especially designed for shaping the marginal portions of shoe uppers into position for attachment to the soles of the shoes.

The invention is herein shown as embodied in a machine for creasing the upper of a shoe and forming the creased portion into a groove in the edge face of a sole. The illustrated machineis paricularly applicable foruse in the manufacture of shoes having Wooden soles, known as'clogs, and

the invention is herein set forth With special reference to that application of it although it is understood that the invention is not limited to this use but may be em ployed With advantage in machines for use in the manufacture of shoes of other types including, for example, stitch-down shoes.

An object of this invention is to provide a machine havin power operated means for forming a definite crease in advance of the Work guide, the crease enabling thework to be'more easily and positively fed along the guide. provide power-operated means acting upon the shoe at the rearward side of the guide which will contribute toward the satisfactory formation of the upper materials into thecrease and enable the same desirable results to be secured Whether the Work is fed from right to left or from left to right.

It is also an object of the invention to pro vide a novel relative construction and arrangement of the Work treating means and supporting means such that the Work is sustained for the action of the treating means While permitting movement of the Work to feed the Work and allowing movement of the Work to and fro for repeated operations of the treating means upon a portion of the Work. 7 Another object of the invention is to pro- A further object is to of the said face is held against the guide; 7 Another feature, of the" invention con' vide improved means. for affording'compensating movement of 'the crease forming tools to ensure thatboth tools Will'enter into engagement with the Work despite inevitable slight departures 0n the part of the operator from correct presentation of the Work to the machine in the course of this tion relatively to the guide and acting,

upon the Work inline with the guide relatively to the direction of feed of the Work, a

that is, along 'the path of traverse of the tool and guide along the Work.

A further feature of the invention consists in improved means by which the crease forming tool is rendered self acooinmodating to the direction in a vertical plane of the face of the Work treated and preferably the construction is'such that the tool is returned to predetermined relation to the guide when displaced by variations of the direction of the face of the Work in said vertical plane. I p a Another feature of the? invention consists in a plurality of crease forming toolsarranged for movements of accommodation to the inclination of the Work relatively to the direction of operation of the crease forming tools and, as herein'shown,

the tools arev interconnected so that elevation of one effects a depression of the,

tool being inadvance of the guide and the other at the rear of the guide relatively to thedirection of the feed of the Work, the

tools being, preferably connected, as described, so that elevation of one relatively to theguide Will produce a corresponding depression of the other relatively to the guide- This construction permits accom-.

modati'on of the tools to the inclination relative'lyto a horizontal plane of the "face Work acted. upon While the is prosistSIin a construction andarrangemen't of a p a part 18 clamped the tools and the guide whereby there is provision for relative movement of 2LCC0111- forming tools to adapt themselves to variations in the direction of the path of traverse of the tools along the work in a horizontal plane.

X further feature of the invention consists in a novel I organization comprising means for operating on one of the edge faces ofa' shoe sole, forinstance in the groove of.

a wooden sole, and means for supporting the edge of the shoe opposite to that beingtreated by the tool with the sole in a substantially vertical position. As shown, the support has an inclined restin face which enables portions of the shoe of varying width to be supported upon the rest without material variation in the inclination of the shoe sole. Preferably the support is adjustable both to varythe inclination and to vary the distance of the rest from the tool. It is important that the point of support ofthe shoe, which preferably is the edge corner of the soleadjacent the tread face and opposite to the operating means, shall remain under the point treated by the crease forming tool, and hence the support is of small lateral extent. This also permits the shoe to be rocked on the rest as a fulcrum in a vertical plane. By rocking the shoe the action of the operating means upon the upper is enhanced and various refractory portions of the upper.

may be repeatedly treated to the action of the operating means, for instance the crease forming tools, by rocking the shoe upon the rest first in one direction and then in the other. I

These and other features of the invention will appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

In the drawings,

' Fig. 1. is a side view of a machineembodying this invention; and

' front view of Fig. 2 is a v tion of the machine.

Referring to the drawings, the numeral 2 indicates the frame of the machine in which are guides 6, 6 for a vertically moving plunger 8. On the plunger 8 is a loosesleeve 10 on the inner side of which is pivoted a link 12 by a pin l l which extends beyond the link to engage a vertical guide 16 formed in at 19 to a hub on the frame 2 through which a shaft 24 extends. Theguide 16 prevents rotation of the sleeve 10 on the plunger 8 and permits vertical movement thereof. The lower end of the link 12 ismounted on a crank pin 20 eccentrically fixed in adisc 23 on the end of the shaft 24 to which power is applied rapidly the forward porto reciprocate the plunger 8 in the guides 6, 6. On the plunger 8 above the sleeve 10 is a nut 26'adjustable to determine the normal raised position of the plunger, the nut being surmounted by a check nut, as shown. Abutting against the lower face of the sleeve 10 is a spring 30 the lower end of which rests on a flange of a sleeve 34: loose on the plunger. Levers 36 are pivoted at 38 to the plunger 8 beneath the flange 32, the plunger 8 being suitably flattened to provide bearing faces for the levers. The ends of these levers are pivoted at dd), 42 to the upper ends of shanks 44, 16, respectively, of crease forming tools 48, 50. The lower end of the plunger 8 is bifurcated to receive a lever 52 pivoted to the plunger at 53 and having its ends bifurcated to receive the shanks 4: 1, 46 which are pivoted thereto by pins 54}, 56. The lower ends of the shanks %,46 approach each other and lie adjacent to a guide 60 located between them and having a rearward extension slotted to receive a cap screw 61 by which it is secured to a stationary portion of the machine. By this construction, the guide is rendered adjustable forwardly and rearwardly of the crease forming tools. The levers 36; 52 constitute a parallel mo tion between the crease forming tools 18, 50 so that the elevation of one effects a corresponding depression of the other, the tools therefor accommodating themselves to an inclination in a vertical plane of the face of.

the work treated by them. It willbe noted also that the plunger 8 is free to rotate in its guides 6, 6 so that the crease forming tools may move forwardly and rearwardly with respect to the gulde 60 and thus accommodate themselves to variations in a horizontal plane of the direction of the groove or angle into which they crease the upper. hen the sleeve 10 is reciprocated by the described connection to the shaft 24;, the plunger 8 and crease forming tools 48, 50 will be positively raised by contact of the sleeve 10 with the nut 26 and will be moved downwardly through the spring 80 to cause the crease forming tools to deliver a yielding blow upon the material in the crease. The crease forming tools, as shown herein, have a shape adapted to fit the groove in the edge face of the wooden sole of a clog. It is within the invention so to change the shape of the crease forming tools that'they will be adapted to operate in the angle between the side of a last and the margin of the sole of a stitch-down shoe. The operating portion of each of the crease formin tools, as shown, comprises a portion formed to enter the crease in the sole of a clog and above the portion 70 is an overhanging portion '72 which not only has a smoothing action upon the upper just above the crease line but also acts to prevent blows of undue force coming upon the material at the bottom of the crease such as would, when operating upon certain materials, cut or otherwise injure them.

To sustain the shoe, a support 80 is provided having a flat tread engaging face 81 covered with leather or other material which will provide a somewhat yielding friction surface. The support is arranged below the crease forming tools 48, 50, in such a position I to the operating means against the surface 81-. The rest 80 extends at an angle to the horizontal of say 60 and forms part of an angle member pivoted to the frame 2. The other arm 5% of the angle membercarries a pin 86 to which is rotatably connected one end of the member 88 which has threaded engagement with a stud 90 on the frame.

- By turning the squared end 92 of the member 88, the angle of the rest may be varied to suit the work being operated upon.
