To all whom it may concern:

Be it known that I, GEORGE E. MILNER, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invent-ed certain new and useful Improvements in Insole -Reinforcing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for applying reinforcing material to insoles, and more particularly to the type of such machine represented in Letters Patent of the United States issued to the Gem Flexible Insole Company as the assignee ofJohn 13.

Hadaway May 10, 1898, No. 603,764. The machine of said patent as constructed to reinforce a lipped insole comprises a Work-sup port, upon which the sole to be reinforced is adapted to rest, a beading or crimping tool, I

a former or anvil which cooperates with the beading or crimping tool to form a bead or crimp in the reinforcing material over the lip of the insole, a presser-tool which presses the reinforcing material against the inner side of the lip, and an auxiliary heading and pressing tool which engages said reinforcing ma terial at the top of the lip and stretches and smooths out the same, at the same time partiall-y conforming the reinforcing material to the lip, whereby said material is caused to lie smoothly against the surface of the insole,

and whereby said reinforcing material as finally shaped and pressed by the beading or crimping tool against the feather and outer side of the lip will be free from objectionable folds and plaits. The'present invention relates to an improvement on the machine above referred to, and moreparticularly to improved means for smoothing and stretching the reinforcing material prior to the action thereon of the heading andcrimping tool.

The object of the present invention is to produce a smoothing and stretching device which will be'inde'pendent in its operations of any of the bead or 'crimpforming devices of such machineand so arranged and operatin g that it will efiectually stretch and smooth the reinforcing material just prior to the ac- To the above end thepresentinvention consists of the devices and combination of devices which will be hereinafter described and claimed.

4: shows in side elevation and partial section the former or anvil, a portion of the mechanism for actuating the smoothing-tool, and the forward end of said tool.

Fig. 5 represents a detail of the pivotal connection of the lever k. I

Similar letters of reference designate similar parts throughout the several views.

In the drawings, A represents the support ing-frame of suitable size and shape to support the working parts. I i

I In frameA are suitable bearings a, in which is mounted the main driving-shaft B, upon one end of which is fixed the hand-wheel G and on the opposite end the pulley D, and shaft B also carries a cam E, provided with suitable path-cams and peripheral cams to actuate the moving'parts of' the machine.

F represents a suitable work support which is revolubly mounted in a yoke or frame f, which is fulcrumed at f to the fixed frame and which at its outer endrests upon a spring f which acts tonormally elevate the outer end of the yoke or frame f and work-support F and maintain the work thereon in position to be acted upon by the bead forming and pressing tools, as will be explained.

G represents the anvil or former, which has a laterally-projecting finger g,over which the reinforcing material is pressed by the beading and crimping tools to form ahead or crimp therein over the lip of an insole.

The anvil or former G is mounted upon the outer end of a lever g, which is fulcrumed at g and carries at its inner end a cam-roll which engages a path-cam g cut'in the periphery of the cam E, the arrangement being such that the rotation of cam E will vibrate the lever g and impart a lateral vibration to the anvil or former G to cooperate with the presser-tool to feed the work.

H represents the presser-tool, which comprises a downwardly and inwardly bent arm h, which is arranged to engage and force the reinforcing material against the inner face of the lip of the insole, and which also forces the outer face of the lip against the outer end of the former or anvil.

The presser-tool H is arranged to have a vertical movement toward and from the work, and to this end it is fixedly secured to an arm h of a lever 71 which is fulcrumed upon a shaft 71 mounted in suitable bearings, (not shown,) the inner end h of the lever h carrying a cam-roll h, (see Fig. 2,) which engages a path-cam in the face of cam E. The presser-tool H is also arranged to have a lateral movement to feed the work, and for this purpose the lever h is prevented from movement along the shaft h but the shaft h is arranged to have a lateral reciprocation in its bearings, it being reciprocated therein by suitable mechanism. (Not shown.)

The above arrangement is such that a r0- tation of the cam E will by means of the lever it cause the presser-tool to have a reciproca'ting movement toward and from the work to press the reinforcing material against the inner face of the lip of the shoe-sole and to grip the work against the end of the former or anvil, and While the work is thus gripped the presser-tool and anvil or former will move laterally to feed the work.

Cooperating with the former or anvil and the presser-tool is a beading and crimping tool I, which may be of any suitable construction and which is arranged to have a reciprocating movement toward and from the work to press the reinforcing material over the lip and the edge of the reinforcing material down onto the feather. The beading or crimping tool I is fixed to the outer end of a bell-crank lever t', which is fulcrumed at i and has upon the end i a cam-r0117), which engages a pathcam formed in the face of the cam E, (see 'Fig. 2,) whereby upon a rotation of the cam E the heading and crimping tool will be reciprocated-toward and from the work. The machine as so far described is substantially the same as the machine of the patent hereinbefore referred to and forms no part of the present invention and has been merely selected for the purposes of illustration only, and the parts thereof may be changed or altered without in any Way affecting the present invention.

In the present invention instead of having the tool which stretches and smooths out the reinforcing material carried by and actuated by the presser-tool I have arranged it to be independent in its operation of any of the bead-forming tools, and it is preferably arranged and operated as follows:

The stretching and smoothing tool is shown at K, it being mounted upon or formed integrally with the lever 70, which is fulcrumed and moved in and out over the material in a diagonal direction to engage the reinforcing material and exert a pull thereon in a diag onal line to stretch and smooth out the reinforcing material.

The lateral movement of the smoothingtool in the outward direction is preferably a positive movement imparted byacam, and its movement in the opposite direction on the inward movement is imparted bya spring, which will insure a quick action of said tool onthe edge of the reinforcing material and its return to its inward position.

The outward movement of the tool K or the outward swing of the lever 70, carrying said tool, is imparted by a pivoted link 70 which at its forward end is connected by a pin k passing through a slot 10 to the lever 70, said link 70 being pivotally connected at 70 to a slide 70, which slide 10 is arranged to reciprocate in a guideway 70 formed by a plate 70 secured by a bolt 70 to the side of the lever g, carrying the anvil or former G, the plate 70 being provided with a slot It in which the fulcrum 10 of the link 7r? is arranged to reciprocate. At its rear end the slide k is provided with a cam-roll 70 which is arranged to be engaged bya peripheral cam I0 on cam E, and the inner end of the slide 70 is connected byaspring 76 to an arm or extension 70, secured to the end of the lever g.

The above arrangement is such thata rotation of the cam E will by means of the peripheral cam 70 impart a forward movement to the slide it, which by means of the link 70 will impart an outward-swinging movement to the end of the lever 70 and the smoothing-- tool K carried thereby, and when the cam 70 releases the roll 10 the slide 70 will be drawn quickly back by the spring 70 thus causing the smoothing-tool K to quickly snap back into its retracted position. The vertical movement of the smoothing-tool K toward and from the work is imparted by a lever m, which is fulcrumed at m to the frame of the machine, said lever being connected by an arm m which is rigidly connected thereto and which at its outer end is pivotally connected at m to a link m whichin turn is pivotally connected at m to a lug or", carried by the link 70 The lever m is arranged to be positively actuated in the forward direction to press the smoothing-tool K upon the reinforcing material to grip it against the anvil or former G by a peripheral cam m7 on the cam E, and said lever is returned in the opposite direction to raise the smoothing-tool K by a spring m ICC e09,11o y a one end of which bears against said lever and the other end against some fixed portion of the frame of the machine.

The arrangement just described is such that a rotation of the peripheral cam m will by means of the lever m, arm m and link m depress the smoothing-tool K upon the reinforcing material, and when said lever on is released by the cam m the spring m will move it backward, thus raising the smoothing-tool K.

The operation of my invention is as follows: The insole with a lip struck up thereon having been provided with a covering of reinforcing material which is cemented thereto along the medial line of the sole, with the free edges of the reinforcingv material extending over the lip and feather preparatory to being beaded and crimped over the lip and pressed onto the feather, is placed upon the worksupport F, with the former or anvil G beneath the edge of the reinforcing material and resting on the feather, its outer end engaging the outer side of the lip and the finger g resting above the lip. (See 'Fig. l.) A rotation of the cam-shaft B will now cause the pressertool H to descend and press the reinforcing material against the inner surface of the lip and grip the lip and reinforcing material against the former or anvil G preparatory to feeding the work one step to the position where it is acted upon by the heading or crimpingtooll. Duringthedownwardmovement of the presser-tool H the smoothing-tool K has been raised by the spring m forcing back the lever 'm and moved outwardly by the cam and its connections, and the cam m engaging the lever m, has depressed the smoothing-tool K upon the edge of the reinforcing material, causing it to press said edge against the top of the lip of the insole and against the former or anvil G, the under surface of the stretching and smoothing tool being roughened or serrated or otherwise formed to frictionally engage the reinforcing material. Just prior to the final downward movement of the presser-tool H and before it presses the reinforcing material and lip of the sole against the anvil or former G the cam 70 releases the cam-roll 7c and permits the spring 7.5 to quickly draw back the slide 70 and the link k which causes the smoothing-tool K to quickly snap back, and because said material is clamped by said tool K it exerts a backward pull thereon to stretch and smooth the reinforcing material. The presser-tool H and the anvil or former Gr now grips the work and feeds it under the beading and crimping tool I, which descends and presses the reinforcingmaterial over the lip and onto the feather, and these operations are repeated until the material has been secured to the insole entirely around the shank and fore part of the sole.

It is to be noted that the smoothing and stretching tool is independent in its movements of the bead-forming tools and that by which is mounted the anvil or former that the stretching and smoothing tool is entirely independent in its movements of any movement of the lever carrying the anvil or former, the slotted connection between the link upon the reciprocating slide and the stretching and smoothing tool permitting a free action of said tool and also a free action of the anvil or former, the action of the tool and theanvil or former being entirely independent of each other.

Having fully described the construction and mode of operation 'of my invention, I

claim as new and desire to protect by Letters Patent of the United States- 1. In a machine for applying reinforcing material to insoles, the combination with bead-forming tools, for forming a head or crimp in the reinforcing material and securingit to the insole,of a stretching and smoothing tool operating independently of said beadforming tools, for stretching and smoothing the reinforcing material, substantially as described.
