SOLE-EDGE-IBURNISI-IING MACHINE.

Specification of Letters Patent.

Application filed January '10, 1914. Serial No. 811,469.

To all whom it may concern Be it known that I, ZOTIQUE BEAUDRY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Sole-Edge-Burnishing Machines, of which the following is a specification.

This invention relates to a machine for setting and burnishing the edges of the soles of boots and shoes and for corrugating the upper edge portion of said sole.

The invention relates particularly to that class of edge setting or burnishing machines for which Letters Patent of the United States No. 931,538 were issued to me August 17, 1909, and embodies an improved presser foot in connection with the edge burnishing irons, whereby the work may be easily and accurately held in position, and which particularly assists in the burnishing and corrugating of the edge of the sole simultaneously, a corrugating wheel being employed on the fore part iron to bear against the upper edge of the sole while the fore part is being set or burnished.

The invention, moreover, relates to improved details of construction of the mechanism whereby the fore part edge burnishing iron and the shank burnishing iron are substituted alternately, one in place of the other, without the operator being obliged to take either hand away from the shoe in order to operate said mechanism.

Still further the invention relates to improved details of mechanism whereby the knee lever which operates the fore part edge and shank iron reversing mechanism is ren dered practicable and convenient.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

sectional elevation taken on line 88 of Fig. 6. Figs. 9, 10, and 11 are detail views illustrating modified forms of presser foot in connection with a sectional view of a shoe in position relatively to the edge burnishing iron and said presser foot.

Like numerals refer to like parts throughout the several views of the drawings.

The machine illustrated in the drawings is designed to be used as a double machine, that is, with a complete mechanism for burnishing the edges of the soles of boots and shoes on opposite sides thereof respectively, the mechanism for such burnishing, however, only being shown on one side of the machine in the drawings.

In the drawings, 10 is the main driving shaft driven by a pulley 11 and belt 12. An eccentric pin 13 is formed upon the end of the shaft 10 and upon this eccentric pin is mounted an eccentric connection 14 which fastened to and forming, in effect, a portion engages at its free end an arm 15 rigidly of a rocker frame 16.

The rocker frame 16 is mounted to rock upon a stationary shaft 17 fast to the frame 18 of the machine. The rocker frame 16 has a downwardly extending arm 19 and on said arm is rotatably mounted a tool carrier 20 consisting of a vertically extending shank 21 journaled to rock in a bearing formed in said arm 19 and a crossbar 22 to which are attached the fore part burnishing iron 23 and the shank burnishing iron 24. The fore part burnishing iron 23 has a corrugating tool 25 rotatably mounted thereon.

The details of construction of the fore part and of the shank burnishing irons and of the corrugating tool are substantially the same as those illustrated in my copending application Serial No. 6at2,147.

The shank 21 has a collar 26 fast to its upper end and is connected to a spindle 27 by a flexible connection 28, preferably consisting of a helical spring. The spindle 27 is rotatably and slidably mounted in the frame of the machine and has fastened thereto a pinion 29 by means of which it may be rotated. A friction roll 30 is journaled to rotate in the upper end of said spindle. A spring 31 encircles the spindle 27 and is contained within a recess 32, while its upper end bears against the hub of the pinion 29 and its lower end bears against the bottom of said recess. The tendencyof said spring is to hold the spindle 2'7 and its pinion gear 29 upwardly, with the cross-bar 22 seated in a recess 33 in the under side of the arm 19.

hen it is desired to change one of the burnishing irons for the other, the spindle 27 is pushed dowinvardly and rotated, so that the cross-bar 32 is pushed out of the recess and the tool carrier 20 is rotated to place one of the burnishing irons in the position formerly occupied by the other. i 'he spindle is then released and is carried upwardly to seat the cross-bar 22 in the recess 33. This change of position of the burnishing irons is accomplished by means of a lever which is pivoted on a stud 35 fast to the frame of the machine and normally held in the position illustrated in Fig. 3 by a torsional soring 36. This torsional spring has one end thereof fast to said lever and the other end fast to a collar 37 rotatably mounted upon the stud 35, whereby more or less tension can be placed upon said spring.

A sleeve 33 is rotatably mounted upon the lever and is fastened thereto by means of a hand nut 39. An arm 40 extends laterally from the lever 3t and is pivoted to the sleeve 33 at atl. The sleeve 33 bears at its lower end against a collar 42 fast to the lever 34, whereby said sleeve is prevented from sliding longitudinally of the lever 34 in a downward direction, but can be adjusted to any desired height thereon by raising and lowering said collar 42 which is fastened to the red by a suitable set-screw.

A knee piece 4C3 is fastened by a hand screw to the arm 40. A flexible member, preferably a chain 45, is fastened at its upper end to the sleeve 38 and at its lower end to a collar 4-6 fast to the arm tO. This collar is adjustable on the arm 40 whereby said arm may be set at different angles relatively to the lever 34 and thus the knee piece 43 may be raised or lowered, as desired.

A spring 47 is fast to the collar -fl6 and thus to the arm 40 at one end thereof and at the other end thereof is fastened to a collar 48 which, in turn, is adjustably fastened to the sleeve 38.

By changing the position of the collar 42 on the lever 34 the arm a0 and sleeve 38 may be moved upwardly or downwardly on said lever, as may be desired. By changing the position of the collar 46 on the arm 40 the angle at which said arm stands to the sleeve 38 may be changed.

When in use the arm l0 can be tipped by the knee of the operator while manipulating the lever 34, while the spring 4:? always'returns said arm to its normal position. When the machine is not being used the arm 40 may be swung out of the way back against the frame of the machine by loosening the set-screw 39 and rotating the sleeve 38 upon the lever 34.

The lever 34: is pivotally connected at its upper end at 49 to a holder 50 which, in its turn, is pivoted to a stud 51 fast to a slide Said slide has ears 53 thereon adapted to slide on parallel rods 5% fastened to the frame 13. A tan-shaped finger is fastened to the holder 50 and said holder has an car 56 extending downwardly therefrom at one side of the U-shaped slide 52. On the opposite side of said U-shaped slide is another ear 57 fast to the holder 50.

Normally the torsional spring 36 holds the lever 34 in the position illustrated in Figs. 2 and i, with the ear 5'? bearing against the slide 52. hen the lever 34- is rocked by pressing the knee against it so as to bring the upper end of said lever toward the front of the machine the holder 50 is rocked from the position illustrated in Fig. 4 to that illustrated in Figs. (3 and 8 and the car 56 then bears against the slide 52. Upon further movement of the lever the slide 52 moves forward and the cam-shaped finger engages the roll 30 and pushes the spindle 27 downwardly, together with its pinion 29, until the pinion 29 is in alinement with a rack 53, said rack being fastened to said slide At the same time the spindle, through the flexible connection 2S,moves the tool carrier 20 downwardly until the cross-bar 22 is moved out of the recess 33 and the spring 23 then rotates the tool carrier 20 until the burnishing tool, which was formerly in position to operate upon the edge of the sole of the shoe, is replaced by the other of said burnishing tools that is, the tool 24 will take the place of the tool 23 and vice versa.

\Vhen the cam-shaped bend 59 in the finger has passed the roll 30 the spindle 2'7 vill be forced upwardly by the spring 31 and upon releasing the knee lever the rack 58 and the holder 50, together with the camshaped finger 55, will return to the position illustrated in Fig. 4. In Fig. 7 the parts just referred to are shown in the position they occupy when the slide 52 is in its forward position.

Collars 60 encircling the rods 5% form stops to limit the distance to which the slide 52 can be moved forward and springs 61 encircling the rods 54 constitute spring buffers against which the slide 52 strikes at the end of its rearward movement.

A pin 62 is mounted to slide vertically in the rocker frame 16 and projects into the recess 33 in which the cross-bar 22 of the tool carrier 20 is located. The lower end of this pin bears against the upper edge of said cross-bar and is in alinement with the particular burnishing tool which is in position for operating upon the edge of the sole of the shoe. Said pin is held with a yielding pressure against the cross-bar 22 by a spring 63 which is forced against the pin 62 with greater or less pressure by means of a screw 6 1 having screw-threaded engagement with the rocker frame 16 and bearing at its lower end against the upper end of the spring 63. The function performed by this springpressed pin is that of abuifer to take the shock of the tool carrier 20 as it springs back into the recess 33 after being given a half rotation.

It is desirable in a machine of the class herein described that the operator should have a support for the sole of a shoe to assist him in holding the shoe accurately in position during the burnishing of the edge of the sole and in the corrugating of the same. Otherwise the shoe is held, as it were, in the air and there is nothing to guide the operator other than the burnishing tool itself which, of course, is a rapidly moving piece and forms a very poor guide in positioning the shoe. The shoe should be positioned independently of the burnishing tool and the burnishing tool allowed to perform its function, which is that of setting and burnishing the edge of a sole. 1 have, there fore, provided a presser foot 65 (see Figs. 2 and This presser foot consists, as a whole, of a plate 66 pivoted at 67 to a carrier 68 which, in turn, is pivoted at its lower end at 69 to a holder 70. A spring 71 is fastened at its lower end to the carrier 68 and bears at its free upper end against the lower free end of the plate 66, thus holding said plate with a yielding pressure against the tread of the sole of the shoe being operated upon. A screw 72 having screw-threaded engagement with the holder bears at its outer end against the carrier 68, thus governing the relative position of the carrier and the holder. The holder 70 and the carrier 68 form, as a whole, a support upon which the presser foot plate 66 is pivoted.

The holder 70 has a shank 73 thereon which is mounted to slide in a boss 74 provided on a bracket 75 fast to the frame of the machine and said shank 73 is fastened to the boss 74 by a set-screw 76 so that the holder 70 and the parts supported directly and indirectly thereon, may be moved to ward or away from the shoe 77 to bring the presser foot plate 66 in proper relation to the sole of the shoe being operated upon, whatever may be th shape or style of said shoe and when soproperly placed with re lation to the shoe and to the edge burnishing tool the presser foot, as a whole, is held firmly in position by tightening the set screw 76.

The rocker frame 16 is adapted to slide upon the shaft 17 longitudinally thereof or in a plane extending transversely of the working face of the edge setting tool 23 and a spring 7 8 is fastened at one end thereof to the frame 18. At the other end thereof said spring is fastened to a plate 79 which is adjustably fastened to the rocker frame 16 by means of a set-screw 80 which projects through a slot 81 in said plate and has screw-threaded engagement with said rocker frame. Thisspring 78 may be utilized to push the rocker frame 16 forward or to pull it back under normal conditions, as, for example, by setting the plate 79 toward the left (Fig. 2) the spring 78 will be brought under compression and will thus force the rocker frame 16 toward the right; or, on the other hand, by setting said plate 79 toward the right the spring 7 8 will be brought under tension and the rocker frame 16 will be drawn normally toward the left, as illustrated in Fig. 2. The limit to which the rocker frame 16 can be moved toward the right (Fig. 2) is regulated by a collar which is fastened to the shaft 17. The object of this construction is so that the'operator can hold the tread of the sole of the shoe against the presser plate 66 and, tipping the shoe transversely thereof, can bring the upper edge against the corrugating wheel 25, thus moving the rocker frame 16 slightly along the shaft 17 and the tension of the spring 78 will then be applied to pressing the corrugating wheel firmly against the upper edge of the sole being operated upon, and thus the impressions of the corrugating wheel upon the upper edge of the sole will be clear and distinct, independent of any slight variations that there may be in the surface of the upper edge of said sole. During this operation of burnishing and corrugating the edge of the fore part of the sole of the shoe, the operator to steady his hand and enable him to accurately locate the shoe and hold it in posi tion during said operation of burnishing and corrugating passes the index finger of .his left hand around the downwardly projecting arm 82of the holder 70, this downwardly extending portion thus constituting a finger rest. 2 I r It will be understood that the presser foot hereinbefore described is used only when the fore part of the sole is being operated upon and when the shank portion is being operated upon said presser foot does not engage the sole of the shoe. This result is accom plished by locating the work rubbing surface of the shank burnishing tool at a greater distance from the median axial line of the M shank 21 of the tool carrier than is the work rubbing surface of the burnishing tool 23 and also by placing the shank burnishing tool at an angle to the median axial line of the shank 21, and the operator by tipping the shoe at a corresponding angle causes the sole in the shank portion thereof to clear the presser foot when the shank por tion is being operated upon.

. Suitable gas pipes 83 and 84 are provided for directing a flame against the burnishing irons to keep the same heated.

After the edges of the sole of the shoe have been burnished and corrugated, as hereinbefore described, the same are subjected to the polishing action of a conveniently located brush 86 which rotates upon a shaft 87 and has a rotary action imparted thereto by a pulley 88, belt 89 and pulley 90. The pulley 90 is rotatably mounted upon a counter-shaft 91 and is rotated by means of a pulley 92 and belt 93.

The general operation of the mechanism hereinbefore specifically described and illustrated in Figs. 1 to 8, inclusive, is as follows: The operator places the shoe with the tread of the sole bearing against the presser foot plate 66 and holds the edge of the same firmly against the working face of the burnishing iron 23, turning the same longitudinally of the shoe in order to bring said burnishing tool in contact with all portions of the edge of the fore part of the sole. At the same time he tips the shoe transversely thereof slightly and causes the corrugating wheel 25 to be pressed into the upper edge of the sole, while at the same time, using the presser foot plate as a pivot, he pulls the rocker frame 16 forward, placing the spring 78 under tension, and thus the edge of the sole of the shoe is set or burnished and the upper edge of the sole is corrugated.

\Vhen the fore part has been finished the operator presses his knee against the knee piece 43, rocking the lever 8-1 and moving the holder 50 upon its pivot to bring the cam finger 55 in alinement with the roll 30. Upon further movement of the lever 34: the iron 2-1 takes the place of the iron 23, as hereinbefore described and the operator then holds the edge of the shank portion of the sole of the shoe against the iron 24 to burnish said shank portion.

lVhile burnishing the edge of the fore part of the shoe the operator steadies his hand, as hereinbefore described, by passing the index finger of his left hand around the downwardly extending portion 82 of the holder 70. When he is burnishing the shank portion he steadies his hand by passing the thumb of his left hand over the rest-rod 94 which is supported upon the bracket 75.

In cases where the fore part burnishing iron is used without the oorrugating wheel and where it is desired to burnish not only the edge of the sole, but that portion of the tread immediately adjacent to the edge of the sole, the spring 78 is placed under compression, as hereinbefore described, and in that case the rocker frame 16 is pushed by said spring outwardly against the collar 85. Then when the edge of the sole is placed against the burnishing iron the operator can push the same away from him or toward the left (Fig. 2), thus bringing the tread portion of the sole immediately adjacent to the edge thereof into contact with the burnishing iron, and by pressing thereagainst the burnishing iron will rub or burnish the tread of the sole immediately adjacent to the edge with a yielding pressure caused by the spring 78 being under compression.

In Figs. 9, 10 and 11 modifications of my improved presser foot are illustrated. Re-

ferring to these figures it will be seen that in Fig. 9 the parts are substantially as in the presser foot illustrated in Figs. 2 and 3, except that a spring 95 is interposed between the holder 70 and the carrier 68 in lieu of the screw 72.

In Fig. 10 the presser foot plate 96 is extended downwardly and has a projection 97 fast thereto which bears against a spring 98 fast to the carrier 68, the carrier 68 being pivoted to the holder 70 as in the form illustrated in Figs. 2 and 3.

In Fig. 11 the presser foot plate 99 is pivoted directly to the holder 100 which constitutes a support therefor and the intermediate plate 68 is omitted. A spring 101 is fastened to the holder 100 and bears at its free end against the free end of the presser foot plate 99.

The form of presser foot illustrated in Fig. 9 differs from that illustrated in Figs. 2 and 3 by having a yielding member interposed between the holder 70 and the carrier 68 to regulate the relative positions of these parts. The presser foot illustrated in Fig. 10 differs from the presser foot illustrated in Figs. 2 and 3 and the form illustrated in Fig. 9 in that the presser foot plate is extended downwardly and bears against a spring located at the lower end of the intermediate or carrier plate 68,

thus supporting the shoe nearer the lower edge as it is held against the burnishing tool than is the case in either of the other forms referred to.

The form illustrated in Fig. 11 is a sim- .Lj

plified form similar in its character and results to the form illustrated in Figs. 2 and 3, but with the intermediate carrier plate omitted.

In the drawings, the corrugating wheel is illustrated with its corrugations of such length as to corrugate that portion of the upper face of the sole immediately adja cent to the edge. It is evident, however,

that the corrugations may be of such length, 5

how the outer edge of the sole can be burnished and the portion of the tread of the sole immediately adjacent to the outer edge thereof simultaneously burnished. It is, however, possible and practicable to burnish or set the outer edge of the sole and also to burnish the tread of the sole adjacent to the outer edge and to simultaneously corrugate the upper edge of the sole adja cent to said outer edge in the machine of my invention by using an iron with a corrugating wheel so placed thereon and of such dimensions that the sole will be a tight fit in the space between the corrugating wheel and the downwardly projecting lip on the bu rnishing iron. By using an iron in which the edge of the sole is a tight fit, as hereinbefore set forth, it will be evident that the outer edge of the sole can be burnished or set and simultaneously the upper edge of the sole can becorrugated by the corrugating wheel 25, while the portion of the tread of the sole adjacent to the outer edge thereof will be burnished by the downwardly projecting lip or guard 23 of the burnishing iron. This possibility of burnishing the outer edge of the sole and the tread of the sole adjacent to said outer edge and corrugating the upper edge of the sole simultaneously by means of my'irnproved ma chine may be clearly seen by reference to Figs. 9, 10 and 11, in which the sole is shown as fitting closely in the channel of the burnishing iron and between the corrugating wheel 25 and the downwardly pro ecting lip or guard 23. p
