DODGE, OF NEXVBURYPORT, DIASSACHUSETTS COUNTER STIFFENER AND METHOD OF FORMING IT Application filed May 11,

In Patent No. 1,%30,158, granted to Milton L. Dodge, September 26, 1922, is disclosed and claimed a counter stiffener having a marginal bead pressed downwardly in its attaching flange, this bead acting to Iorm the upper about the heel seat portion of the shoe into a corresponding shape and thus facilitating the formation of a close joint with the edge of a wood heel. Then a counter stiffener provided with such a head is used in a shoe of a type such as the McKay or welt where lasting is effected on a bed laster after the counter stiffener is in position, the pressure exerted between the heel seat wipers and the shoe during a portion of the lasting tends to flatten the bead at the heel end of the shoe and it this is permitted the utility of the bead is seriously impaired. The present inven tion, therefore, has forits object to so protect the bead portion of the stiflener that it can withstand the flattening pressure with out substantial deformation. To this end the bead at the heel end of the stiffener is formed up from the material of the flange into a substantially solid cross section which is able to effectively resist deformation under the lasting pressure.

For a more complete understanding of this invention reference may be had to the ac companying drawing in which Figure 1 is a view partly in elevation and partly in section showing a mechanism for forming the desired bead.

Figures 2 and 3 are sectional details through the forming dies showing a stiffener in position therebetween at difierent stages of the cycle of operations of the mechanism.

Figure 4 is a detail section on line h& of Figure 1.

Figure 5 is a detail front elevation of a die Figure 6 is a side elevation partly broken away and in section of a stiflener constructed in accordance with this invention.

Figure 7 is a fragmentary section similar to a portion of Figure 3 but showing a modication.

Referring to the drawing, at 1 is indicated a support from which rises a standard 2 pre An arm 4 1931. Serial No. 536,365.

is hinged at 5 to the support 1 remote from the face of the wall 3 and this arm slidably carries at its upper end a form 6 over which may be placed a counter stiffener 7, shown in dotted lines in Figure 1, this counter stiffener 5 having formed therein about the outer margin of its attaching flange portion 8 a hollow head 9. On the forward face of the wall 3 is fixed a plate member 10, which, as shown best in Figure 5, is formed substantially heel shape but of sufiiciently smaller size than the counter so as to substantially fit within the marginal bead 9 on the outer face of the stiiiener in the position shown in Figure 1. y The form 6 is shown .as normally held elevated, this being accomplished by carrying this form on the upper end of a plunger 12 having a head 13 seated in a socket 14 in the arm 4 and pressed upwardly by a spring 15 I carried in the socket and supported at its lower end on a threaded plug 16 which closes the lower end of the socket.

The form 6 is further guided for vertical movement relative to the arm 4: as by means of a bolt 20 extending through a slot 21 in the lower end of the form 6 and threaded into the arm 4. Slidably carried in any suitable manner by the standard 2 is a molding member or block 25, the lower face of which is recessed as at 26 to form a seat to engage so over the heel end portion of the stilfener placed over the form 6. The inner edge portion 27 of this face is formed to engage the rear faceof the head 9 of the stifl'ener and gradually merges withthat portion of the 'face which engages the back face of the stiffener so that aft-er the molding operation is complete there is no line of demarcation between the bead and the rear wall of the stiii ener. Where the stiffener is unprovided with a bead an undesirable sharp edge is formed on the outside of the stiffener at the juncture between its wall and the attaching flange, by the molding operation, and while this sharp edge as at 28 on Figure 2 is not so pronounced where a head is molded in the flange, nevertheless it is even then noticeable and is also undesirable. This may be effecby treatment in l 0 tually eliminated, however, accordance with this invention by which this juncture is rounded over by the molding pressure between the form 6 and the member 25. The member 25 is mounted for vertical movement by any suitable guiding means (not shown) so that after the stifl'ener has been placed over the form 6, which may be tilted forwardly into the dotted line position shown in Figure 1 for this purpose, and is then allowed to drop rearwardly, it is positioned directly above the form 6. On exerting downward pressure on the block 25, the form 6 with the stiffener carried thereby, is pressed downwardly. The upper edge of the plate 10 engaging the material of the counter flange being stationary this causes the material of this flange to be forced or crowded backwardly toward the heel end of the stiffener and gathered together so as to substantially fill the inner hollow face of the bead, as is shown in Figures 3 and 6, as at 30. This pressure also causes the arm 4 to press rearwardly thus to shape the lower face of the bead against the forward face of the wall 3. If desired, also, the member 25 may be provided with a cam plate 35 engageable with a cam face 36 on the outer upper portion of the form 6, this acting further to crowd the form rearwardly toward the wall 3 as is shown in Figure 3.

As shown in Figures 1, 2 and 3 the upper edge of the plate 10 may be substantially at right angles to its forward face but in Figure 7 a modification is shown in which this top edge face is beveled as shown at 38. This causes the flange material to be pushed toward the heel end of the stiffener in a somewhat different manner than by the edge shown in Figures 1, 2 and 3 but in either case this action may be continued sufficiently to cause the rear portion of the bead to be formed up with a substantially solid cross section which is amply able to withstand the pressure of the heel wipers during the bed lasting operation without substantial deformation.

From the foregoing description of this invention, and mechanism by which the desired forming operations may be carried out, it should be evident to those skilled in the art that various changes and modifications might be made without departing from the spirit or scope of this invention as is defined by the appended claims.

I claim:

1. A counter stiffener having an attaching flange, said flange having an external marginal bead, said bead at the heel end of said stiffener being of substantially solid cross section and being formed from gathered flange material.

2. A counter stiffener of sheet material having a counter attaching flange provided with a marginal outwardly extending bead having a portion of substantially solid cross secnature.
