Application August 24, 1931, serial No. 558,916

insert a temporary fastening device, such asv for instance a screw for clamping the cemented heel firmly against the lasted shoe while .the cement is setting. Subsequently, after the cement has set, the temporary fastening means has been withdrawn and the shoe delasted, it is the usual practice to nail the heels in position. In view of the fact that itis of considerable importance in the manufacture of high grade shoes that the Wood heel be accurately and properly aligned with the sole as well as the upper, it is advantageous that the operator whov temporarily attaches the heels to the shoe be able to fully view the heel and lasted shoe while the heel is ,being placed thereupon and clamped. 1t has been heretofore the practice generally that a shoe be supported with the bottom thereof down as the temporary securing device is being applied to the. heel and accordingly in View of the fact that the voperator could not properly view the work, the heels have, in many instances, been/ secured in position without proper alignment so that the beauty which the shoe might otherwise have is not present.

An object of this invention, generally stated is yto provide a wood heel attaching Amachine having the parts constructed and arranged to support the shoe with the bottom thereof extending upwardly during the' application of the usual temporary securing device.

Another object of this invention is to provide a wood heel attaching machine having a shoe support mounted for movement relative to the usual clamp in order to facilitate of the shoe and heel.

A further object of this invention is to provide a machine of the kind described with al device for accurately aligning a lasted shoe upon a support.

Another object of this-invention is to provide a wood heel attaching machine in which the device for ldriving-the temporary securing device is accurately guided by the framev of the machine.

'Other objects will become apparent to those skilled in the art when the following description positioning is read in connection with the accompanying `drawing in which: p i

Figure 1 is a view in side elevation of a wood heel attaching machine constructed in accordance with this invention. y Figure 2 is a view infront elevation of the movable shoe support employed on the wood heel attaching machine illustrated in Figure 1.V Figure 3 is a perspective view of a heel engaging member.

Generally stated, in accordance with thisgin'- vention, the operative parts of a wood yheel attaching machine are so constructed and arranged that the shoe being operated upon isv supported with its bottom up in order that it -may be clearly viewed by the operator and accordingly with the shoe vso supported means is provided for inserting or driving the usual ternporary securing device into the heel and through a hole in the last upwardly into the heel while at the same time suitable clampingmeans is provided fois mounting the wood heelA to be secured in position upon a lasted shoe.

Referring now particularly to the drawing, a wood heel attaching machine constructed in accordance with the present invention is shown and in the embodiment illustrated, the temporary fastener driving device shown is of a type particularly adaptable for use in connection with a last provided with a temporaryv securing means disclosed in U.S. Patent No. 1,898,288. patented February 21, 1933, in which a last is provided with a permanent assembly including-asecuring device such. as for instance a screw, bu't it will be distinctly understood that thermachine of the present invention is not limited tl'o use in connection with such a securing device, but may be advantageously employed in applying the ordinary screws Awhichare usually employed. 'I'he machine illustrated in Figure 1 is provided with a suitable frame 1 which may be in thenature of a pedestal mounted upona suitable base 2 and carrying at its upper end a` guiding arm 3 hav-v ,ing cylindrical portions 4 adapted to receive in vslidable relation thereto a bar 5. The bar 5 extends downwardly within the pedestal 1 and may be provided with a suitable cushioning device as a spring 6 having one end thereof seated against an abutment 7 on the interior of the pedestal 1 and the other end thereof engaging a suitable abutment as a collar 8 mounted upon the bar 5. With such an arrangement, it is` apparent that the spring 6 will tend to force the bar 5 upwardly relative to the pedestal 1, untiLthe weight of the ,bar and its associated parts'jllst balance the force of the spring 6 at which time the parts will come to rest. Pivotally attached to the lower end of the bar is a link 9 having one end thereof pivotally attached to a treadle 10 pivotally supported by a suitable lug 11 on the base plate 2. The treadle 10 preferably extends outwardly from the frame of the machine to a `convenient position for operation as illustrated in Figure 1. At its upper end, the bar 5 10 carries an arm 12A which is-*provided at its outer end with a suitable guideway 13 adapted to receive in slidable relation thereto a bar 14. Suitable adjusting means is preferably provided whereby the position of the bar 14 may be varied 15 within the guide-way 13. For instance, the guideway 13 may be of a split construction and provided with a suitable adjusting screw as 15 for tightening the same in order to maintain the bar 14 in fixed position therewithin. Pivotally mounted upon the lower end of the bar 14 is a heel engaging member 16 having an abutment 1'1 adapted to engage the top lift of a wood heel and suitable abutments 18 which are preferably of nonabrasive material adapted to engage the face of a heel.

Extending outwardly from the pedestal 1 is a suitable frame part or table 19 which may be integrally formed with the pedestal l so that a continuous frame structure is provided. Suitable re-enforcing ribs as 20 may be provided for strengthening the frame thus formed. Mounted upon' the. upper surface of the table 19 is a shoe support 21 provided at the top thereof with a post 22 adapted to enter the usual thimble such as 23 of the last 24. In accordance with the present invention, the shoe support 21 is connected to the table 19 through a hinge connection 25 so that the support 21 is tiltable, as indicated by the arrow in Figure 2, about a shaft 26 as an axis. With such an arrangement, it is apparent that an operator may tilt the shoe support 21 to the side, as illustrated by the arrow in Figure 2, for a distance sumcient to permit a lasted shoe to be readily placed thereupon and while thus tilted, the operator may if fdesired position the wooden heel to be applied to the shoe in proper alignment. With the lasted shoe and its corresponding heel thus positioned, the support 21 may be returned to the position illustrated in'Figure 2 where, it will be understood, that the shoe carried thereby with its corresponding heel as 27 will be positioned for cooperation with the heel engaging member 16. When the operator is ready to proceed with v. V lapplying the temporary fasteningdevice, he mayA then step upon the treadle 10, which will cause the bar 5 to be moved downwardly and with it the arm 12, as well as the heel engaging member 16. It is apparent, therefore, that the apparatus, including the bar 5, the treadle 10, the arm 12and the heel engaging member 16, cooperate as' a clamping mechanism to clamp the heel upon a shoe which is held in stationary position .with reference to the frame of the machine.

A The sho'e support 21 is in accordance with the l present invention provided with a device adapted to cooperate with a last thereupon to align the shoe upon the support. Such an aligning device may beI in the nature of a plate 28 hingedly connected toa support as through a shaft 29 and preferably provided with a stiff leaf spring 30 having one end thereof secured to the support 21 and the other end thereof in engagement with the plate 28 tending to force the same in a 'l5 clockwise direction as seen in Figurel. As is .anism in its vertical travel.

clearly illustrated in Figures 1 and 2 the plate 28 is of such length that vthe end thereof extends upwardly beyond the end of the support 21 and as shown in Figure 1, the plate 28 is so disposed as to engage and cooperate with the inclined portion 31 of the last adjacent the cone. With such an arrangement it is apparent that if the spring 30 be of suicient stiffness, the force thereof acting through plate 28 will be effective to cause the inclined portion 31 to become accurately aligned with the plate 28 in view of the fact that the last is rotatable about the post 22. It is apparent, therefore, that with such a positioning device as the plate 28 the shoe will be accurately positioned upon the support before being moved into position for cooperation with the clamping device and other cooperating parts to be now described.

In order to drive the temporary securing device, which is usually employed for attaching wood heels, into position suitable driving mechanism is provided. Such driving mechanism may comprise a suitable chuck as 32 adapted to receive a tool 33 for cooperation with the temporary securing device or fastener 3.4, but it may be pointed out that in lieu of the tool 33 and fastener 34, an ordinary heel attaching screw may be employed in which case such a tool as 33 will be unnecessary and it will be further understood that the head of the chuck 32'may be so formed as to receive any suitable or desired head which may be provided upon `the usual securing device or fastener. Attached to the chuck 32 for driving the same is a shaft 35 extending through an aperture 36 in the table portion 19 of the frame so as to guide the same in its movement axially thereof as the chuck 32 is being moved toward a shoe in order to force the fastener into position. It may be pointed out that the shaft 35 is preferably connected through a yieldable drivingmechanism which may be of any desired type in order to prevent the transmission of a driving force in excess of the predetermined value to the tool 33. The drivingv force for the shaft 35 may be transmitted 120 through a suitable flexible shaft as 37 from a gear or chain drive mounted in a housing 38 and driven by a. motor 39. It will be understood that a suitable'driving mechanism such as for instance .a worm and a worm gear may be mounted in a housing 40 for transmitting the driving force from the flexible shaft 37 to the shaft 35.

A lever 41 is pivoted through a suitable lug as 42 to the frame of the machine and is attached through a'link 43 to theside of the housing 40. `A spring such as 44 may be provided for supporting the housing 40vand its adjunct parts and a bifurcated member as .45 having one prong thereof extending on each v'side lof the shaft 3'7 may be provided for a guiding mech- It is apparent, therefore, that after an operator has positioned the shoe and its corresponding heel upon the support 41 and has stepped upon the treadle 10 140 in order to clamp the heel in position upon the shoe, he may then grasp the lever 41 and lift the same upwardly in order to move the tool 33 into position for. cooperative engagement with the temporary securing device or fastener 34. 145 'I'he operator may continue to lift upwardly upon the lever 41 until the fastener 34 is driven home at which time the yieldable connection for the shaft 35 will begin to slip, thus indicating to the operator that the fastener is driven home, where- 150 upon the lever 4l may be released and the parts willv drop into the position shown in Figure 1, being cushioned in their downward movement by a. spring 44. -At the same time, theoperator may release the treadle 10 whereupon the clamping parts Awill be moved by the springe lupwardly thus releasingv the pressure upon the heel V2'7.

From the foregoing description it is believedy that the operation of a machine constructed in accordance with the present invention will be apparent and it will be seen that a wood heel attaching machineA is provided in which the shoe to be operated upon is supported in such a position that an unobstructed view of the heel and the heel seat may be had by the operator while the parts are being placed in position. It is apparent that many modifications of the machine hereinb'efore described and illustrated in the accompanying drawing will present themselves to those skilled in the art without departing from the spirit of this invention. It is to be distinctly understood,l therefore, that the invention is not limited to the specific details which have been hereinbefore set forth and that such modifications and the use of such individual features and sub-combinations of features as do not depart from the spirit of lthis invention are, although not specifically 'described herein, contemplated by and within the scope of the appended claims.
