WELT-BEATING MACI-IL'NE.

Application filed April 15, 1921.

To ail whom it may concern."

Be it known that I, FRED N. LA CHAPELLE, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Halt-Beating 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 apper tains to make and use the same.

The present invention relates to machines for use in the manufacture of shoes and more particularly to machines for use in beating out a welt after it is attached to the upper and insole of a shoe to cause the welt to lie flat substantially in the plane of the insole.

The sidewise deflection of the welt in applying it to the toe of a shoe, particularly of a pointed toe shoe, causes this portion of the welt to turn or curl up, and in order for the welt beating machines at present in common use to properly beat out the welt it is usually necessary to provide this portion of the welt with a series of cuts or slashes in its under surface to enable the outer edge thereof to stretch sufliciently during the beating out operation to bring it into the plane of the insole. It has been found, however, that in certain classes of work, such cutting or slashing of the welt is obj ectionable as the slashes tend to weaken the welt. Accordingly, the principal object of the present invention is to provide a novel and improved welt beating machine which is adapted to properly beat out the welt without the necessity of subjecting the welt to a slashing operation.

The principal object of the invention is to provide a novel and improved machine of this type which is adapted to operate effectively upon the portion of the welt extending about the toe of the shoe as well as upon the portions extending about the sides of the shoe without the necessity of subjecting the welt to a slashing operation and without danger of weakening or otherwise injuring the Welt.

With this object in View a feature of the invention contemplates the provision in a Welt beating machine of mechanism for beating out a welt which mechanism is capa- .ble of being controlled. during the operation of the machine to vary the force of the blows imparted to the outer edge portion of Serial No. 461,557.

the welt as compared with the force of the blows imparted to the inner edge portion. With this construction it will be apparent that during the operation of the machine when the toe of the shoe is reached, the welt.

beating mechanism by being controlled to impart blows acting with greater force on the outer edge portion than on the inner edge portion of the welt to compensate for the curled up condition of the welt about the toe of the shoe, will cause the outer edge portion of the welt to be stretched sufliciently t enable it to lie flat in the plane of the insole, and while operating on the remaining portions of the welt, the welt beating mechanism may be controlled to op erate in the usual manner to impart blows acting with substantially the same force on both the outer and inner edge portions of the welt. It will also be apparent that with this construction it is not necessary for the welt to be slashed before or during the welt beatinu operation, and as the welt may be maintained substantially flat during the welt beating operation there is no danger of the welt being scarred or otherwise injured. In the preferred embodiment of the invention the objects of the invention are attained by the provision of a reciprocating hammer and a cooperating anvil which are adapted to be relatively adjusted during the, opera tion of the machine to vary the angular relation of their working faces in such a manner that the force of the blow of the hammer on the outer edge portion of thewelt may be varied as desired. This result may, however, be accomplished in other ways, as by providing a wedgeshaped tool which may be inserted between the welt and the anvil to act as an auxiliary anvil to cooperate with the hammer when the toe portion of the welt is reached, the tool being withdrawn while the machine is operating on the remaining portions of the welt to enable the anvil and hammer to act in the usual manner.

For the sake of simplicity of construction such relative adjustment of the hammer and anvil is preferably accomplished by adjusting the anvil, and in the preferred em bodiment of the invention the anvil is adapted to be adjusted in an are about a point substantially at the forward edge of the working face of the anvil so that the force of the blow on the outer edge portion of the welt may be varied without materialy affecting the force of the blow 011 the inner edge portion of the welt.

Other features of the invention consist in certain constructions, arrangements and combinations of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.

The several features of the invention will be clearly understood from the following description and accompanying drawings, in which:

Figure l is a right side elevation of the upper portion of a welt eating machine embodying the features in their preferred form with the casing of the machine shown in section; Figs. 2 and 3 are sectional plan views taken on the lines 2-2 and 3--3 of Fig. 1; Fig. t is a detail side elevation of portions of the hammer and anvil engaging a welt with the an il adjusted to cause the hammer to strike with greater force on the outer edge portion of thewelt than on the inner edge portion; Fig. 5 is a side elevation oi. a welt beating machine which is a modification. of the machine illustrated in the preceding figures; Fig. (3 is a detail side elevation of a portion of the hammer, anvil and impact receiving tool or auxiliary anvil, the hammer and auxiliary anvil being shown acting on the work; Fig. 7 a plan view of themachine illusi't-rated in F 5; and lli 's. 8 and 9 are detail plan and end elevations of an impact receiving tool or auxiliary anvil constituting a component part of the machine illustrated in Figs. 5 and 6.

The machine illustrated in Figs. l to l, in elusive, of the drawings is provided with a vertically reciprocating hammer f2 and a cooperatinganvil l. The hammer 2 is formed on the lower end ot a downwardly spring pressed plunger rod t3 mounted in a cylindrical bearing 8 forming a part of a vertically reciprocating carrier it). The carrier 10 is vertically guided by a rod 12 secured to the carrier and mounted to slide in a cylin drical bearing 14: formed on the forward portion of a bracket arm 16- projecting from a bearing post 18 ofthe frame of the machine. The upper portion of the rod 12 extends through a vertical aperture in the rear end of an arm 20, forming a part of the carrier 10, and is clamped to the arm by a shoulder 22 formed on the rod engaging the lower side of the arm and a clamping nut 23 screw-threaded on the upper end of the rod. The hammer and carrier are held from lateral movement by bosses 24 formed on opposite sides of the arm 20 in sliding engagement with gibs formed on the casing or frame of the ma chine. The carrier 10 is verl'i fially reciproated by a driving shaft 30 extending through and jourualed in a bearing formed at the upper end of the post 13. The connection between the driving shaft 3t) and the carrier 10 comprises a balance wheel secu ed to the forward end of the shaft and carrying a roll 3% mounted eccentrically to the shaft which engages a horizontal groove formed in the rear end of the arm 20 of the carrier. t will be apparent that this mechanism for acti'iat-ing the hammer is of simple construction and will operate at high speed without undue shock or jar.

The rear portion of the anvil is bifurcated to provide segmental arms 38 arranged at opposite sides of the cylindrical bearing l-l of the bracket arm l6. T he outer sides of the segmental arms 38 are provided with grooves 10 which are concentric with a point at the forward e-zilge of the. working face of the anvil and are in sliding eng c ment with tongues or gibs 42 formed on r posite sides ot the machine casingi W" this construction. it will be apparent that by shifting the anvil on the tongues or gibs the working face of the anvil may be tilted about its tea-ward edge as a center. The means for thus adjusting the anvil compria rock shaft extending through and jour naled in the bracket 16 between the cylindrical boss ti and the bearing post The connection between the shaft 4A and the anvil comprises an eccentric dish to secured to the right hand end of the shaft which on gages a blocl-t l8 mounted to slide between gibs 5U projecting rearwariflly from one or the segmental arms 38 of the anvil an arm 52 is secured to the left hand end of the rock shaft ell and is connected by a rod 5a with treadle mechanism at the base of the machine.

Upon depressing the treadle rod the rear portion of the anvil is moved upwardly on the gibs 42 to tilt the working face of the anvil upwardly at an angle to the working face of the hammer. Upon releasing the treadle rod 5% a spring connected therewith acts to move the rear portion of the anvil downwardly to its normal position against a stop pin 56 secured to the lower end of one of the gibs at?) which positions the working face of the anvil in a horizontal plane or in a plane substantially parallel with the working face of the hammer. ll hilc operating on the portions of the welt extent ing about the sides of the shoe the anvil is thus held with its working face in a substantially horizontal plane, that'the harnmer will operate with the s:- no force on the outer and inner edge portion of the welt, and when the portion of the welt extending about the toe of the shoe is rcacln-zcn the operator by depressing the treadle rod 54 will tilt the working face of the anvil to cause the hammer to act with greater force on the outer edge portion of the welt than on the inner edge portion, as illustrated. in Fig. 4:. it will be apparent that by depressthe operator mayvary the relative beating out action or blowsimparted by the hammer on the outer and inner. welt.

The machine illustrated in vlligs. 5 to 9, inclusive, is provided with a stationary anvil 58 and a reciprocating hammer 60. The anvil 58 is formedon the forward end of a bar 62 which is supported on a bracket64 projecting from the frame of the machine and is secured to the bracket by a bolt 66. The bolt 66 extends through an elongated slot in the bracket and is screw threaded into the bar 62 toprovide for longitudinal adjustment of the anvil. The hammer 60 is formed on the lower end of a downwardly spring pressed plunger rod 68 mounted in a cylindrical bearing 70 formed on the forward end of a rocking beam 72' The beam 72 is pivotally mountedmidway of its ends on a stud shaft 74 supported by ears 76 on the machine frame. The rear end of ,the rocking beam 72 is bifurcated to engage a block 7 8 pivotally mounted on an eccentric 80 formed on the driving shaft .82, by means of which the rocking beam is actuated to reciprocate the hammer. .The hammer is so positioned that its working face is in aplane substantially parallel with the working face of the anvil when the hammer strikes the work, and during the operation of the machine on the portions of the welt extending about the sides of the shoe the hammer and anvil cooperate in the usual manner to beat out the welt. When the portion of the welt extending about the toe of the shoe is reached a tool or auxiliary anvil 84 is moved into position between the welt and the anvil 58 to cooperate with the hammer in beating out this portion of the welt. The working face of the tool 84 is substantially of the same size and shape as the working face of the anvil, and the tool is relatively thin and wedge-shaped to enable it to be easily inserted beneath the welt and to cause the outer edge portion of the welt to receive a greater stretching or beating out action than the inner edge portion by the impact of the hammer as illustrated in big. 6.

The tool 84 is formed on the forward end of a plunger rod 86 extending through and mounted to slide in a cylindrical bearing 88 and held from turning movement by a key 90 on the bearing engaging a longitudinal slot in the plunger. The plunger 86 is urged forwardly by a spring 92 coiled about the rod and interposed between a shoulder on the rod and a shoulder formed near the rear end of the cylindrical bearing 88, and such forward movement of the rod is limited by stop nuts 94 screw-threaded on the rear end of the rod engaging the rear end of the hearing. The cylindrical bearing 88 is formed on a depending bracket 96 proedge portions of the tool to inoperative position.

vanced .andretracted to move the tool 84 into and ontof operative position by means ofa bell crank 100 pivotallymounted on a stud 102 secured to the frame of the machine. The upper end of an arm 103 ofthe bell crank .100 ,is .bifurcatedto engage a block 104 pivotallymonnted on thesliding bar ,98,.and theptherarm of the bell crank is connectedhy a rod1106 with treadle mech anism at the base ofthemacliine. The arm 103 is urged.rearwardly.against a stop pin 108 secured -t o the machine frame to maintain thetool .84 in inoperative position by means; of a.,coil spring 110 connected with the arm. With thisconstruction it will be apparent that upon depressing the treadle rod 16 ,6tlie tool .84 may be moved into operativeposition, andthatupon releasing the treadle rod-the spring 110 will return the The yielding connection between the tool 84 and the sliding carrier 98 obviate s any ,danger of the worker parts of the machine being injured in case it is attempted to advance the tool while the hammer is in engagement with the .work.
