GHINERY CORPORAIC)1N',` `0F PATEK-SGN, ,NEW JERSEY, A"CORPORATION OF NETV zrnnsiivA n Application led .Tune 1,
This invention relates to shoe finishing machines of the type in which a heated tool` is used for performing a burnishing operation on some part of a vshoe as, for example, the edges of a sole.
In machines of this type employing ra rapidly vibrating iron, it is desired to mount the iron so as to permit alimited angular movement for purposes @of self-adjustment inthe iron. It will be 'apparent that such an arrangement subjects the iron to severe wearing conditions and, in commercial practice, many irons have to be discarded before their operating faces are worn out on account of the excessive angular play which develops in the holder on account of this Wear.
y In one of its aspects, the present'invention consists in a novel construction of holder and iron whereby the necessary limited angul; lar play is permittedand at the same time excessive and objectionable wear is eliminated. To this end, and 'in accordance with an important feature of the invention, the illustrated iron and holder have a swivel connection which includes a socket with ai complete unbroken cylindrical surfaceand positioning member having a flat face of substantial area acting on vthe exterior of the iron to resist the rotation of the tool and to limit its angular' movement in the holder. By thus providing contact faces of substantial area, the wear upon the iron is eliminated or reduced to a-minimum. In machines of thistype, it is a practiceto employ interchangeable tools or irons shaped in accordance with the contour of the particular work to be operated upon and itis important, 'ac- `.cordingly, so to design the tools thatrthey may be readily removed from the holder and Yasreadily replaced in operative position.
The pressure of thelatch ordinarily em-y ployed to retain the edge iron on theoholder is insufiicient appreciably to hinder theremovalof 'the iron orthe replacement of. another.k I-Iowever, if, in'addition Sto a latch Vfor retaining the'iron on the holder, a position'ing memberfor resisting rotation oft-he iron on the holder is arranged to bear squarely against the iron, the increased frictional resistance between the iron and its holder,
SHOErrisirsmive MAGHINE 192.8. SeriallNo. 284,853.
owing to the pressure of the positioning member against the iron, may be-sutiicientto cause difficulty inthe removal of the iron l from the holder. It is therefore another object of the invention to provide, Vin a burnishing machine having a latch for holding the edge iron to the holder, means for limiting the angular movement of the edge iron necessary for its self-adjustment, the presence of which means does not render the removal of the iron from the holder. anyV more diiiicult. In accordance with this'feature of the invention the flat face on the iron is disposed obliquely to its axisrso that.upon a very slight retractive movement of the V iron, the obliquely disposed face is removed from engagement vwith the cooperating posi-y tioning member.-V In order that tliereshall be no lost motion between the edge iron and the positioning'member, when such a condi-` tionis desired, the latch is constructed and arranged to engage a face on the iron oppositely inclined to the face of the iron which is engaged by the positioning member; and the latch, therefore, acting againstthe cooperating face onf the edge iron, tends to move it to hold the iron in engagement with the positioning member. Similarly, the positioning member, bearing against the inclined cooperating face on the edge iron, resists any rotative movement thereof and provides 'an abutment for the iron determining e its position on the holder. y
In one formV of shoe finishing machine, the tool is heated by a-s'taticnary heating unit havinga plane radiating face7 the tool being located and moved inclose proximity thereto. Another feature of the invention consists `in afnovelform of ironadaptedparticularly well to cooperate with a heating unit .of this character and, accordingly, to improve the eiiciencyof the heatV transfer. To Vthis end, the Villustrated iron is formed with ther side which is-disposed tcwardtthe heating unit as a continuous flat'face extending from one end Y ofthe tool tothe other and for thel full width thereof;y In this way, the maximum area of the tool is made available to receive heat by radiation.
v v i l 1I `In machines wherein the burnishmg iron is oscillated at a high rate of speed, it has been found that a smoother action and less vibration of the machine is secured by making the general contour and construction of the iron symmetrical. In another aspect, ac-
' shoe finishing machines of different types and thev invention in this respect is, therefore, of general application.
These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shownin the accompanying drawings, in which Fig. 1 is arview in side elevation, partly in section, of the head of an edge setting machine;
E ig. 2 is ar view in perspective, on an cnlarged scale, of the tool, the tool holder and the electric'heating.unit; and
Fig. 3 is a view in perspective ofthe holder and tool separated from each other.
Y Since thel invention may be applied to edge setting machines of any commercial type, it is notdeemed necessary to illustrate the whole machine herein and, consequently, only the head is shown. This comprises an oscillating rock shaft which projects outwardly froma frame 12 and which is oscillated at a high rate of speed in a fashion common in such machines. Upon the outer end of the shaft is mounted ahead 14 having'oppositely projecting arms 15 and 17 which are recessed to receive cylindrical toolholders 16. The tool holders 16 are yieldingly mounted in the receptacles in the head and retained'in place by stop barsQO set in the head1-i and traversing a slot formed in the body of the holder, as shown in Fig. .2. Each of thel holders 16 carries a detachably mounted edge iron and it is customary to equip the machine with a. forepart iron in one holder'and a shank iron in the other. The head 14 is latched in operative position but is arranged to be rotated through half a revolution to present either iron inoperative posit-ion, as required by the operator.
The mechanism for holding and rotating the headlwill not be herein described since it formsfno part of the present invention. The headillustrated, however, is similar to that shown in Letters Patent of the United States No.l 1,757,188', granted May 6, 1930, on an application of VilIiam'Hamann, to which reference may be had for a completedisclosure of 'this construction. Electrical heating units 30, each havingr a iiat radiating face, are mounted in the machine in stationary position so as to heat both irons, that is to say, the lowermost iron while it is in operative position and the uppermost iron while it is in inoperative position.
Each tool holder 16 comprises a plunger having a projecting swivel pin 22 at its outer end. Each plunger has a flat portion formed adjacent to its end, to which are adjustably secured a spring retaining leaf or latch piece 24 and a positioning member 26. Both of these members are of sheet material and each has a slotted shank for the reception of a clamping. screw 25'. The retaining member Qis curved inwardly at its outer end to constitute a spring detent. The outer/end ofthe positioning member 26 is bent inwardly at an acute angle, forming a portion Q8 with a` face lisposed obliquely with respect to the spindle 2 and having a substantial area. The members 24 and 26 are assembled in superposed relation and may be adjusted longitudinally together or separately and clamped in adjusted position by the screw 25.
The burnishingtool or iron ii() is formed with its end surface to fit the edge contour required in the sole being operated upon. The body of the iron is substantially rectilinear in shape and provided with a longitudinal bore i2 disposed symmetrically so that the iron will be in substantial balance about its longitudinalaxis. It will be seen that the bore 42 has a continuous unbroken cylindrical wall, there being no key or keyway in either the pin Q2 or its corresponding socket. ln this way, a maxin'ium bearing surface is provided between the iron and the pin upon which it is mounted and the best possible conditions of wear are thus secured.
In its outer face, the iron 40 is provided with aftransverse groove l-lof curved contour which cooperates with thc curved end of the spring retaining member 24e when the iron is positioned upon the pin 22 to detachably retain'the iron againstl longitudinal displacement. At the same time, the iron may be removed when desired by forcing it sutiiciently to spring the end of the retaining member out of the groove. Between-the'groove 44 and the inner end of the iron vis formed a positioning face 46 whichis disposed obliquely at an acute angle to the axis-ofr the iron and oppositely inclined to the adjacent side of the groove 44. This face cooperates with` the transverse positioningface 28of the member 26 ywhen the iron is held in operative position vby the spring detentf asshown for example. in Fig. 2. The Contact face 46 of the iron and the correspondingface of the inturned end 28 of the positioning piece bear over a'substantial area and serve to rlimit the angular movement of the iron upon the pin 22; This movement, as already stated, must be slight hut should preferably be provided for. The
It' wiilbe understood that the inner or rear face of the iron which is disposed toward the heating unitBO is formed as a continuous flat face extending from oneend of the tool to the other and for the full width thereof. rI`his face is located in close proximity to the plane radiating face of the `heatingunit and, accordingly, the iron presents the most favorable shape possible for receiving heat by radiation from the heating unit.
