Specification of Letters Patent.
Application filed January 5, 1905.
Serial No. 239,713.
To all whom it may concern:
Be it known that l, ANnunw EPrLnn, citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful luiprownnents in ShoeTurning Machines; and l 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 11d use the same.
The present invention relates to improvements in shoe turning machines which are used tor turning the rear or counter portion of a turn shoe and which comprise a form, and a plunger movable into and out of the form and cooperating therewith to turn the rear or counter portion of a shoe over the form.
In the shoe turning machine illustrated in. the application of the applicant filed April 16, 1902, Serial No. 103,150, dithculty has been experienced, in the operation of the machine, in the entrance of the plunger into the fornulowing to the tact that in the shoes operated upon the thickness of the materials upon one side of the plunger issometimes greater than the thickness upon the other side, with the result that the plunger crowds or jams in entering the form, sometimes causing the shoe to be ripped, and always necessitating the application of greater force than is needed to do the work. It is proposed according to the present invention to overcome this defect by provid ing means for supporting the plunger and form so constructed as to permit relative verscly of the sole of a shoe placed on the form, whereby they may adjust themselves to the thickness of the materials between the sides of the form and the plunger when the plunger is entering the -form.
In the accompanying drawings illustrating the preferred embodiment of the present invention Figure 1 is a side elevation of the machine, Fig. 2 is a vertical section of the upper end of the plunger carrying arm, Fig. 3 is a section on the line ae-rc Fig. 1, show iug the springs for yieldingly holding the plunger in position, Fi t is a vertical sectional elevation of the form carrying turret, Fig. 5 is a bottom plan of the turret, two of the arms being broken away, lookingin the directionolitihe axis of the turret, and
Fig. 6 is a plan of the face of the turret carrying lever showing the recesses which are engaged by the deteut carried by the turret.
The plunger 1 cooperates with the form 2, in the manner illustrated and described inthe said application, to turn the shoe. The plunger 1 is provided with a shank 3 which is received in a split socket 4 in an arm 5 secured upon the forward end of the shaft (3, which is mounted in a bearing 7 on the lower ends of the arms of the fork 11 carry springs 13 which bear upon the opposite sides of the web 12, the thickness of the web 12 being somewhat less than the distance between the arms of the fork 11. Adjusting screws 14 are provided for adjusting the pressure of the springs upon the Web 12 and by these means the proper position of the plunger with relation to the form may be secured.
The forms 2, are constructed like those shown in the patent to Meyer, No. 763,620,
June 28, 1904, being provided with a belt 15 running over the curved rear ed o of thc form and in close proximity to tie' outer and inner surfaces of the rear wall thereofi The forms 2 are three in number and are mounted upon the turret 16 which in turn is mounted upon the form carrying lever 17. A stud 18 passes through a hole inthe center of the turret ltiand affords a pivotal support for the turret. A spring 19 is interposed between the head of the stud 18 and the bottom of the recess in the turret which said head This permits the turrot to move axiallyRin order to withdraw the detent 20 secured upon the bottom of the turret from engagement with a recess 21 in the face 22 of the form carrying lever. The severalforms 2 are diite rent in size and the poitions of the recesses 21 are such that when the detent is in engagement With'a recess the turret will be held in proper posi tion to present one of the forms in proper cooperative position with relation.,;;-.-to the plunger 1.
The capacity of the plunger to yield in entering the form is preferably limited so that the plunger cannot strike the form but at the same time it is sullieient to com ensate for irregularities in the thickness 0 the materials in the shoe so that the plunger may center itself with relation to the materials and the form as it begins the shoe turning operation.
The present invention is not limited to the illustrated embodiment thereof but may be embodied in Widely dilierent forms.
Having thus described theinventiomwhatis claimed is 1. A machine for turning the rear or counter portion of a turn shoe, having, in combination, a form over which the shoe is turned, and a plunger movable into and out of the form, said plunger and form having provision for relative movei'nent transversely of the sole of a shoe placed on the form as the plunger enters the form, substantially as described.
' 2. Amaehine for turning the rear or counter portion of a turned shoe, having, in combination, a form over which the shoe .is turned and a plunger movable into and out of the form mounted to move transversely of the sole of a shoe placed on the form as the plunger enters the form, substantially as described.
In testin'iony whereof I 'atiix my signature, in presence of two witnesses.
