SOLE-BEVELING MACHINE.

Application filed September 30, 1918. Serial No. 256,227.

To (/ZZ whom it may concern:

Be it known that I, Fnnnnnro E. Bun- TRAND, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Sole-Beveling 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 machines for operating upon blanks and is herein illustrated as embodied in a. machine for use in the manufacture of pieced solos. Such soles are commonly made of two pieces, a heel piece and a fore piece, fastened together by a cemented bevel joint; and the illustrative machine is shown fitted for beveling heel pieces.

In beveling the heel pieces or other blanks chips are removed. from the ends thereof, and commonly the chips and the finished blanks are allowed to collect in a common receptacle. According to one feature of the present invention the chips and the finished blanks are deposited in separate localities so that sorting of the finished blanks from the chips is obviated. In the illustrative machine a movable chute is out of blank receiving position during the severing and depositing of the chip and is then moved into position to receive the finished blank and deliver it to a locality separated from the locality in which the chips are deposit.- ed; and preferably the movement of the chute is an angular one, the angular inclination of the chute being increased as soon as the finished blank has been deposited on the receiving end thereof so that the sliding of the blank down the chute will be facilitated.

It desirable that the beveling out be accurately made so that the cemented joint of the pieced sole or other article may have sufficient strength and that the chip removed be as small as possible so as to save stock.

Accordingly another feature of the inven' tion comprises a gage which is moved into the path of the blanks to locate the cuts and then out of said path to permit the chips to be deposited in one pile or receptacle as well as to permit the finished blanks to be advanced to the chute and thereby delivered to another pile or receptacle.

Another feature of the invention is to be found in an improved organization provlding automatically operating mechanism properly coordinated for successively feeding blanks and trimming them, as for example by reciprocating a knife against successive blanks to form a bevel at one end of each blank. Preferably a tiltable knife is provided, and the knife and the blank support are relatively moved to form angularly related cuts, as for example to change the angle of the bevel. In the illustrated embodiment of the invention, as regarded from this point. of view, there are provided a magazine for a stack of blanks, a support adjacent the magazine, means for removing blanks successively from the magazine and feeding them over the support, a knife or equivalent cutter mounted as described, and means for relatively moving the support and the knife for trimming the successive blanks.

These and other features of the invention including certain details of construction and combinations of parts will be described as embodied in an illustrative machine and pointed out in the appended claims.

Referring to the accompanying drawings,-

' Fig. 1 is a side elevation of a machine in which the present invention is embodied; Fig. 2 is a plan View of the machine;

3 is a perspective of the mechanism for operating the movable gage;

Fig. 4. is a perspective of the mechanism for operating the feed slide;

Fig. 5 is a perspective of the mechanism for operating the movable chute, and

Fig. 6 is a detail of the feed slide.

The blanks herein shown as heel ends of soles are fed one by one from the bottom of a stack in a magazine 1 by a feeder having a feed slide 3 the slidable supporting bar 4 of which has a rack on its under side with which a pinion 5 meshes. This pinion is fast to a shaft 7 to which is also fast. a smaller pinion 9, this latter pinion being engaged by the teeth of a segmental rack 11. The arm 18 which carries the rack at its outer end is fast at its inner end to one end of a rock shaft 15, the other of the rock shaft having fast thereto an arm 17. A finger 18 at the extremity of the arm 17 runs in a cam track 19 formed in a cam member 21 which is fast to a rotary shaft 13. hen, therefore, the shaft 23 is rotated the feed slide will be reciprocated to feed the blanks one by one. For a reason which will presently appear the feed slide 3 is moved forward yieldingly. Referring to Fig. (5, the feed slide is adjustably held by screws 5 on a feed-slide carrier 8 which is slidablc in a dove-tailed groove in the bar 1 and is normally held in the position shown by a spring 10. This spring fits in a socket in the bar and engages a downwardly extending projection on the forward end of the carrier 8, thereby tending to hold a downwardly extending projection on therear end of the carrier againstthe rear end of the bar 4:. The effect of this construction is to feed the blank yieldingly so that the movement of the blank may be arrested without breaking the feed mechanism.

Each blank is fed over a table 25 until it contacts at its forward edge with a gage 27, the arresting of the blank being permitted by the spring 10. In the illustrative machine the first blank does not contact with the gage until the next succeeding blank pushes it forward. While the blank rests against the gage 27, a knife 29 is caused to enter the blank near its end; and as soon as the knife has entered the blank the gage 27 is moved down out of the way so that when the knife has finished its inclined cut and been withdrawn and the blank has been moved slightly forward, the chip may drop down over the gage 27. As soon as this has taken place a chute 31 or ejector, which has thus far been in inoperative position, is swung in a counterclockwise direction until its left-hand end, as viewed in Fig. 1, is below the plane of the table 25 when it is in position to receive the blank which has just been operated upon as the blank is pushed forward by the preceding blank.

The mechanism for raising and lowering the gage 27 comprises an arm 33 fast at one end to a rock shaft 35 and having at its other end a. segmental rack 37 which meshes with the teeth 39 of a rack formed on the gage 27, said gage being vertically slidable in upright guideways in the frame of the machine. A second arm 11, fast at one end to the rock shaft 35. has fast at its other end a finger 43 which runs in a cam track 45 formed in the side of a large gear 47, said large gear being fast to the shaft 23 and serving to rotate it through an idle pinion 19 and a large gear 51 which latter is fast to the rotary shaft 53. The gear 51 is driven from apinion 55 on the driving shaft 57. A wheel 59 fast to the shaft 53 provides means for turning the machine over by hand. In order to permit such turning readily, the

pinion 55 is splined to the shaft 57 and is held normally in operative position in mesh with the large gear 51 by a spring 60 which rests at one end against a collar 62 fast to the shaft 57 and at the other end against the hub of the pinion 55. hen it is desired to turn the shaft 53 over by hand the pinion is pushed along the shaft 57 until'it is out of mesh with the gear 51 and is locked in inoperative position by being turned slightly on the shaft, suitable locking means being provided for this purpose on the pinion and on the shaft. 7

The chute 31 has formed on its under side a perforated lug through which the shaft 53 loosely passes so that the chute may be swung about the axis ofthe shaft. In order so to swing the chute at the proper times a link 61 is pivoted at 63 to the under side of the chute at the left of the shaft 53, as viewed in Fig. 1, and is pivoted at its lower end at 65 to an arm 67 the hub of which is fast to a small shaft 69, said shaft being free to rock in bearings in the frame of the machine. A second arm 71 also having its hub fast to the rock shaft (39, has at its outer end a finger which runs in a cam track 73 forn'ied in the side of the gear l' i hen, therefore, the shaft 53 is rotated the chute 31 is swung first in a coimter-clockwise direction to bring it into position to receive the beveled or finished blank and then in a clockwise direction into the position shown in Fig. 1. The blank 100 slides down the chute and may be delivered into a receptacle of some sort (not shown). The chips and the finished product are thus separated.

The knife is 'iustably mounted in a slide the cpoosi 3 ends of which run in inclined guid 7 in the sl de carrier 9. (libs 73 owned on the upper walls of the guidewa may be atijusled by screw bolts 8 to rate up wear caused of t by the moven knife slide 75, said slide being v nesting rods 83 l at 85 to the knife slide and hay their lower ends cccentrie straps S. which encircle eccentrics on the shaft The knife 29 is dove-tailed into an undercut guideway in the slide 75, and threaded into the knife is an adjusting screw 8:; the head. of which extends into a slot in a bracket said bracket having a slotted base. The stem of a screw bolt 93 passes through the slot and threaded into the knife slide. The purpose of the slotted base is to permit the i) acket 91 to be moved out of register with the head of the thumbscrew 89, when desired, so that the knife may readily be remover. from the machine. When the parts are in the position shown, the knife may be adjusted in its guidcway by turning the thumb-screw 89.

In order to permit varying the angle of the cut made by the knife 29, the slidecarrier 79 is angularly adjustable. To this end itis mounted upon trunnions 95 which are sup iorted in suitable hearings in the frame oi the machine. and is provided with upstanding: lugs 97 having segmental slots struck about the axis of the trunnions 95. Screw bolts 99 pass through these slots and are threaded into bosses 101 which are part or" the frame of the machine. These screw bolts clamp the lugs to the bosses and serve to hold the slide-carrier 79 in adjusted angular position.

The operation of the machine is as follows: The blanl's are fed one by one from the bottom of the stack. The leading blank is at first merely pushed out upon the table 25, and is then pushed forward into contact with the age 2'? by the neat succeeding blank. After the leading blank is in contact with the page, the knife descends until it enters the. blank near the end thereof. The gage is then lowered and the knife finishes its out and rises out of the blank. The finished blank is then advanced and the cut-otl chip falls over the page 27 and may be cau ht in a suitable receptacle, a passageway through the machine being provided for its tall. Meantimethe chute 31 is being swung into receiving position, and when it reaches this position the forward portion of the finished blank is pushed into the chute. V hen the reator portion of the finished blank has been pushed into the chute, the gage 2? rises into the position shown lifting the rear end of the blank, thereby acceler ating its movement into the chute and tak ing up a position to engage the forward end of the next blank. swung into the position shown the blank slides down and is delivered from it as shown in Fig. 1. The "Further operation of the machine is a repetition of the cycle which has been described above. In practice the actuation ot the driving shaft 57 is controlled by a clutch which may be manipulated either to cause the shaft to rotate continuously or to cause it to make one revolution. In either event when the power is thrown oil the machine comes to rest in the position shown. this clutch torm no part of the present invention and any suitable clutch may be used, it has not been shown or described.

Although the invention has been set forth as embodied in a particular machine it should be understood that the invention is not limited in the scope of its application to the machine which has been shown and described.
