SHOE-FORMING MACHINE.

Continuation of application Serial No. 509,684, led July 20, 1909.

Serial No.

To all whomv it may concern Be it known that I, RONALD F. MCFEELY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Shoe-Forming Machines, of which the following' description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to shoe forming machines and is shown as embodied in a machine for shaping a lasted shoe to prepare it for the reception of an outer sole.

An important feature of this invention consists in the combination of a reciprocating bottom pounder with a side beater which is so arranged relatively to its actuating mechanism that the beater remains at rest until it has been pressed upon by the work to establish an operative connection wit-li its actuator.

The beater is preferably so mounted that when it is actuated it moves upwardly, as well as outwardly toward the shoe, so that it tends to work the stock toward the edge of the shoe bottom. The side beater is arranged to serve as the side rest for the slice and assist the operator in presenting the shoe in proper relation to the bottom pounder. The side beater may serve the purpose of a guiding device alone when a portion of the shoe is being treated which does not require beating at the side and then, as the operation progresses, and the portion of the shoe is reached which it is desirable to beat on the side, the operative connection of the beater to its actuator may be established by increasing` the pressure of the shoe against the beater. It is characteristic of this beater' that it remains continuously in engagement with the upper and beats the slice by repeated outward and upward impulses as distinguished from blows imparted by moving the beater away from the side of the shoe and then against itas has heretofore been proposed.

A further feature of this invention con- Speciiication of Letters Patent.

This application i'iled October 16, 1909. 523,072.

sufficient pressure to render the side beaters `operative without eort on the part of the Qworkman.

It is found to be a great relief to the workman and to insure more uniform and better results to cause the machine to hold jithe shoe in posit-ion to receive the action fof the beaters of which the one shown as Voperating on the bottom of the shoe as well as the side beaters constantly act to force :the shoe laterally away from the machine. Tliis novel feature is embodied in means iwhich operates to press the shoe yieldingly jagainst the side beaters while permitting `the shoe to be turned and fed along, which is the only work required of the workman,

lin accordance with this feature of the in- .vent1on, while the beating operation on a shoe is in progress. The shoe holding means yis arranged to permit movement of the shoe and itsy carrier away from the machine to facilitate the application and removal of the shoe and to lock the slice carrier autoniatieally in its position remote from the machine. The shoe carrier is shown as a heel spindle adapted to hold welt shoes for the operation of beating the heel seats, but

the invention is as well applicable to use with a shoe carrier for supporting a shoe for the entire bottom to be beaten such, for

example, as the jack shown in my co-pending application Ser. No. 509,684, filed July 20, 1909, of which the present application is a continuation as to subject matter which vis common tol it and to the disclosure in that application. It will be understood from the foregoing that in this embodiment of the invention the heel spindle is a carrier that is movable, either by operating meansconnected with it or by force transmitted through the shoe, to present the shoe to the side beaters, and that such presentation of the shoe in this machine can be made to establish an operative connection betwee normally stationary side beaters and their actuator; and furthermore, that the machine preferably includes means acting' through the shoe carrier and tending normally to press the carrier and the shoe toward the machine, and also means to lock the carrier and the shoe in a position away from the machine.

These and other features of the invention will be more fully explained in connection with the description of the machine in which they are herein shown and embodied vand will then be pointed out in the claims.

Figure 1 is a side elevation of the machine which is of the same general type as that shown in my earlier application; F ig. 2 is a plan view on line QM?, Fig. 1; F ig. 3 is a perspective view for the purpose of illustrating the side beater.

The column Q of the machine has a head t provided with bearings in which is mounted a shaft 5 which drives, by means of an eccentric stud 3, a il-shaped rocker G. 1n the front face of the rocker is formed a groove by which is made a sliding connection with a link 8, having formed upon it, or upon a block connected with it, a segment rack by means of which the link can be moved upwardly or downwardly toward and from the center of oscillation of the rocker. The rack is engaged for this purpose by a pinion 12 meshing with a segment lever let connected by rod 11 with a foot treadle which, as in the machine of the prior application, is also a starting treadle connected. with a rocking lever 13, Fig. 3, and is arranged to be first depressed for throwing in a clutch 1T that drives the shaft 5, and then to be further depressed for adjusting the link relatively to the rocker to vary the length of the stroke imparted to the link.

rlhe initial depression of the starting treadle to throw in the clutch 17 for driving the shaft 5 at the same time operates through the segment lever 11i to turn the pinion 12 to move the segment rack and linkv 8 upwardly from the lowermost position of the link toward the center of oscillation of the rocker G. This lowermost position of the link 8 is preferably at an approximately neutral point with respect to the axis of Oscillation of the rocker so that in this position the link El has little or no movement imparted to it. Preferably, too, the arrangement is such that, upon depression ot the treadle, the link S will not be moved from its neutral position until after the clutch 17 is thrown in and the shaft 5 is thus started. Thereafter, a slight further depression of the treadle will move the link 8 upwardly a sufficient distance to cause short strokes to be imparted to the said link while, upon still further depression of the tr iadle, the strokes imparted to the link 8 may be lengthened as desired without affecting the clutch and hence without discontinuing the operation of shaft 5.

The link S is joined at its front end to a vibrator 15 for the tool carrier 1G in which is mounted the bottom pounding tool 20. The vibrator and t-he carrier are both mounted on the same pivot or fulcrum 18 and the upper arm of the vibrator extends into an inclosed space in the tool carrier where it is located between two cushions 19, which preferably will be rubber blocks. The arrangement of these cushions within an inclosure in the tool. carrier is an improven'ient over my prior construction in that it protects the rubber blocks from the oil and dust which would otherwise deteriorate the rubber. rlhe bottom pounding tool will be actuated from and toward the shoe by the described connection 1G, 15, S, 6 with the eccentric 3, and the tool is preferably mounted to slide lengthwise in its carrier 16. lilith this arrangement the tool is actuated backwardly in its carrier by its inertia as the carrier completes its upstroke and is actuated forwardly by its inertia and a spring 2l to force the upper inwardly from the edge of the shoe when it comes down upon the shoe, all as more fully explained in said prior application.

The shaft 5 is provided with a cam Q5 adapted to operate a vibrator 26 which is fulcrumed in the machine at QS and connected to a tool carrier 80 on which the side beating tools are mounted. A spring 32 normally holds the vibrator and the tool carrier forwardly with relation to the fulcrum 28 and maintains the vibrator out of contact with the cam 25. The tool carrier 30 is at its forward end forked to extend under the bottom pounder and has laterally projecting ledges 34 arranged between a supporting member 85 on the head et and a plate 36 at the lower end of a spring pressed plunger 38. The ledges 3l are inclined as appears clearly in Fig. 1, so that as the tool carrier is moved forwardly, the side beaters are given a component of upward movement which causes them to work the upper toward the edge of the last. rlthe side beating tools 40, of which one is arranged on each side of the bottom pounder 20, are swiveled upon the tool carrier 30 to turn about horizontal and upright axes, as shown, to enable them to adapt themselves to the contour of the shoe. rThe tool carrier has stop .faces at 42 which limit the tipping movement of the side beaters about their horizontal axes and the beaters are formed with downwardly and backwardly receding faces.

1t will be apparent from the above description, that the bottom pounding tool Q may be started or stopped entirely independently ot' the side beating tools 41 and while the latter continue in operation merely by so positioning the treadle that the link 8 is in its neutral position without, however, throwing out the clutch 17. Similarly, so long as the clutch 17 is not atfected and the shaft continues to revolve, the side beaters A() may be started or stopped at will independently of the bottom pounder 20 and while that tool Continues in operation.

The shoe carrier herein shown comprises a heel spindle pivotally supported at its lower end by a horizontally adjustable bar The spindle is preferably vertically unyielding but readily adjustable lengthwise as explained in my prior application. rEhe spindle is guided in a yoke member which extends laterally from the trame ot the machine and also within a slide 5G which is movable horizontally in guideways in the yoke 55 and is pressed normally toward the trame of the machine by springs 5S. This slide is arovided at the outerI side of the spindle with a spindle engaging block G0 turning on a horizontal axis and at the inner side with a latch 62 pivoted at 63. The latch has a horizontal arm the end tace ot which is adapted to engage with an end face G5 on the yoke when the spindle and slide are moved away from the machine into position for the removal or application of a shoe and to lock the spindle in this shoe receiving position. A spring 6G actuates this horizontal arm into position to engage the abutment when the spindle is so moved outwardly. An upwardly extending arm of the latch stands in position to be engaged by the spindle when the latch is locked and to be rocked into position to turn the horizontal arm away from the abutment so that merely by pressing the shoe and spindle toward the machine the latch is unlocked and the springs 58 are permitted to draw the shoe into operative relation to the tools. Upon such movement ot' the spindle with the shoe toward the beating tools, the shoe is not only positioned for the action of the bottom beating means, but, at the same time, by such movement of the spindle and shoe, the vibrator 2G is brought into contact with the cam 25 and the operation of the side beating means is started. 1V hen it is desired to move the shoe away from the machine that is done against the resistance of the springs 58 and the latch is automatically actuated by the spring GG to lock the spindle in the remote position. Upon such reverse movement of the spindle and shoe away from the machine the operative connection between the vibrator and its cam is broken and the operation of the side beating tools thereby stopped. rlhus it will be seen that the starting and stopping of the side beating tools are controlled automatically by movement of the spindle or shoe supporting` rest with the shoe toward and from the machine. The yoke and its carried parts are adjustable from and toward the machine and are held in place by the set bolt 70.
