13,565. 011311131 No. 957,986, dated Kay 17, 1910,

Be it known that I, GEORGE T. MoLEoo, a citizen of the United St ates,residing at Boston, in.the county' of Suffolk and State of Massachusetts, have invented an Improvement in Heel-Breasting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The aim of this invention is to provide means for so trimming the breast of a 'shoe heel that the angle between the tread surface of the top lift and the breast of the heel will be in all cases uniform for a given style of shoe or shape of heel.

In the shaping and trimming of the breast of a heel it is diflicultto maintain at all times a uniform angle between the tread and the breast thereof, unless some means is provided which will firmly hold the heel in position during the cutting or trimming operation. In consequence of this fact; not only is there lack of uniformity of the shape of the heels of shoes of the same style, butin many cases an extremely clumsy and otherwise unsightly heel is produced, whereby the shoe to which it is attached is rendered unfit In the drawings: Figure 1 is a front view of the machine; Fig. 2 is a side elevation, partly section, on the line 2-2 Fig. 1; Fig. 3 is a detached side elevation of the angle block and adjacent parts; Fig. f1 is a plan view of the parts shown in Fig. 3: Fig. 5 is a detached view of the-breastgage and operating mechanism therefor; Figs. 6 and 7 are side and rear views, respectively,partly in section, of the jack operated mechanism;

Figs. 8 to 12, inclusive, are views of details herelnafter to be described.

a The form of mechanism illustrated in Figs. 1, 2, and 3 of the drawings, by which the desired results are accomplished, compr ses a suitable jack, 1, pivoted upon a block, 2, and held in normal position by a spring, 3, and supported u on a stem, 4, in a This suppo is capable'of a sliding movement in suitable guides from front to rear of the machine ,and vice versa. The stem, =1, of the jack, is vertically movable in the support, 5, and is preferably constructed in two sections, an uppersection attached to the block, 2, and a lower section terminating in a foot, 6, the two sections bemg united by adjusting means, as a screw 7 and a knurled nut, 8, located in a suitable enlargement of the support, 5, whereby the height of the jack may be varied proportionately to the height of heels in different styles of shoes.

A suitable stop, 8, preferably spring operated, see Fig. 9, cooperates with the nut 8, to hold the stem, 4, in adjusted position, and the stemis presented from turning in the support 5, by means of screws, 4, which engage slots, at 4, in each section thereof. Vertical movement is imparted to the stem, 4, by means of a cam operated plug, 9, located in the bed plate of the machine upon which the foot, 6, tests when the jack is in rearward or operativeposition. Above the jack and cooperating therewith for positioning the heel, is ananglilarly adjustable presser plate, 10, which is mounted in an adjustable head, 11, at the rear of the machine, and positioned to extend over-the heel portion of the jack when the latter is in rear operating position'and at such a heightas to clear the heel of a shoe on the jack when the latter is in its normal, depressed position. A gage device, 12, PEOVidQd with the beveled faces 12' and '12", constituting gages Figs. 3 and 4, slidably mounted upon a pivoted supporting stem, 13, is normally positioned above the path of the jack, 1,, as shown in dotted outline, Fig. 3, and is also provided with means hereinafter described to bring it at the proper time to.its operative position shown in full lines, Fig. 3. I

The operation of the parts thus far described is as follows: A shoe is placed by the operator upon the jack, 1, when in its forward position, as shown in dotted outline, Fig. 2. The jack is then slid to the rear upon the bed of the machine by means of the hand-piece 17, until the base of the support, '5, comes in contact with the adjustable screw, 14, attached to suitable mechanism for tripping the gage device, 12, from its elevated to its operative position. Upon tripping the gage devices 12, the gages take a position in the path of the heel of the shoe upon the jack, whereupon the operator pulls the jack and its support forward until the gage device contacts withthe breast of the heel and thus stops the shoe in proper position under the pressure plate, 10. For a right shoe the face or gage 12 of the gage device is used and for a left shoe the face or gage 12 in order to give the heel breast a slight .angle transversely of the shoe as required in some styles, the somewhat loose fit of the shoe upon the jack readily allowing of such adjustment. Thejack is now elevated until the tread surface of the heel of the shoe thereon contacts and bears squarely on said presser plate, the jack turning on its pivot to allow the heel to accommodate itself.

to the position of said plate. During the elevation of the jack, the gage device 12 is caused by suitable mechanism hereinafter described, to move slightly forward to clear the heel and then upward to its elevated position, where itis held until the next operation of the machine. WVhen the heel has the presser plate, 10, aicutter,.15, suitably mounted above and slightly forward of the presser plate, descends and trims oil the breast of the heel to the proper shape and at an angle to the tread surface thereof, determined by the position to which the presser plate, 10, has been adjusted. With the presser plate adjusted to a given position, it is obvious that all heels operated upon by the knife will invariably present uniform angles between the breasts and the tread surchine.

faces thereof.

- Thesupport, 5, is provided with a base,

17, in the under side of which is a dovetailed groove, 18, which engages a guide, 19, upon the bed, 20, of the machine. The base, 17, also is recessed at 21, immediately below the support, v5, said recess extendin a short distance to the front and rear of said support and inclosing the foot 6, on the jack stem. To operate the jack stem, 4, the vertically movable plug, 9, in the bed plate, 20, is provided with a cam roll, 22, which normally engages a recess, 23, in the cam, 24, the latter being journaled at 25 in the bed of the ma- An operating arm, 26, extends from the cam, 24, and is connected by a link, 27, with the treadle, 28, pivoted at 29 in the frame of the machine. When the cam, 24,

is rotated by the-operation of the treadle, the cam roll, 22, is raised out of the recess, 23, thereby raising the plug, 9, and the jack stem resting upon it is raised upon the rising slightly to allow for slight variations in the heights of heels in the same style of shoe. The supporting block, 34, is adjustably supported in the head, 11, which is itself ad- ]ustably mounted upon the standard, 39, rising from the bed plate, 20. Any suitable means may be adopted for adjusting the block, 34, but as here shown, it is constructed in the form of a sector provided with grooves, 40, on its curved face, which en age a rib, 41, on the opposite curved face 0 t e head, 11. In order to hold the block, 34, firmly in its adjusted .position, a plate, 42 provided with a slot,'43, may be attached thereto, through. which slot projects a set screw,'44, mounted in the head 11.

The breast gages, 12 and 12 Fig. 4, may be mounted and tripped in any suitable manner, but as here shown they are supported by'a gage device 12, which extends from a sleeve, 45, slidably mounted on a pivoted arm, 13, and maybe held from rotation on said arm by a tongue, 46, projecting into a groove, 47 in the latter. justably held in position upon the arm, 13, by means of a nut, 48, and a spring, 49, interposed between the sleeve 45, and an abutment 50, on said arm. Any suitable means may-be adopted for operating the gages, but

in the construction illustrated herein, the

rocker arm, 13, is pivotally mounted at 51, upon a depending rocker arm, 52, which in turn is pivoted at 53 to the head 11, and (see Fig. 11) is spaced from said head by a sleeve 53", on the said pivot,'53, in order to bring said arm, 52, into proper position relative to the arm, 13. The upper end of the arm, 52, may be provided with a cam slot, 54, in which operates a stud, 55, adjustably mounted upon a slotted arm, 56, which is provided 'with an extension, 57, mounted upon a vertically reciprocating part, 58, hereinafter described. I

Referring to Fig. 5, an adjusting screw,

59, mounted in an arm, 60, attached to the rocker arm, 52, contacts with rocker arm 13, at certain intervals, to hold said arm and the breast gages 12 and 12, attached thereto inoperative position in the path of the heel,

The gages are ad-,

therewith, whereby the plate will yield 62, at the rear of the machine, to a convenient part, as an arm, 63, on the standard 39, is normally held by a spring, 64, in the path of a stud, 65, on the arm, 13, to retain the breast gages normally in inoperative posi-- tion. To operate the latch 61, there is pivoted at its lower extremity an abutment arm 66 provided with the adjustable abutment V screw 14, which lies in the path of the mov-' able base 17 of the jack standard 5. When the jack support 5 is moved to the rearand contacts with the abutment screw 14, the latch 61 is tripped, allowing the gages to 'drop until arrested by a stop 59. The stud,

55, is now caused to descend, thereby rocking the depending arm, 52, throwing the lower end forward and moving the breast gages also slightly forward, clear of the breast of the heel, and upward to the position shown in dotted lines, Fig. 5. At the same time the stud, 65, on the rear end of the arm, 13, engages the beveled upper extremity of the latch, 61, and moves the latter forward to the dotted .line position, Fig. 5, whereupon the stud clears the bevel and the latch springs back over said stud, so that when the arm 52 is returned to initial position, the arm, 13, and the breast gages, will be held in their inoperative position, as

A shown in dotted outline, Fig. 3.

The cutter 15, referred to, is adjustably mounted in any desired manner on the vertically reciprocating crosshead, 58, Fig. 2; As shown in Fig. 2, the knife is secured to a carrier, 69, provided with a vertical slot toreceive a bolt, 70, by means of which the out ter may be adjustably secured to the cross head. A plate, 71, is interposed between the carrier, 69, and the crosshead, 58, and is provided with guide ribs, 72, to hold the cutter carrier in proper vertical position. A set screw, 73, mounted in a suitable ex-v "tension on the plate, 71, serves to limit the upward adjustment of the cutter and toform an abutment to hold the latter-against upward pressure, due to cutting through the leather of the heel.

Q -The crosshead, 58, may be arranged and actuated in any desired manner, but is here shown as slidably mounted upon the standards, 7 4, which rise from the bed, 20, of the machine and are united at their upper extremity .by an arched yoke, 75, and also by the rearwardly extended converging arms, 76, which unite in a hub, 77, engaging the upper extremity of the standard, 39. Springs, 78, surrounding the standards, 74,

serve to support the 'crosshead, 58, in its upper position, and alsoto return parts of the machine to normal position, after each operation thereof. To actuate the crosshead,

depending rods, 7 9', connect the latter with a yoke, 80, which is'actuated by the treadle, 28, through 58, carries a stop rod, 82, which rises through an aperture in the yoke, 75, and is provided above the same with set nuts, 83, which may be adjusted to limit the length of the stroke of the cutter, in order that the latter may completely trim the breast of the heel of the shoe operated upon without cutting into the sole shank.

From the foregoing description it will be obvious that with a machine so constructed, it would be possible for an unskilled operator to perform the usually diflicult operations of breasting the heel of shoes with absolute accuracy and uniformity. All that is required of the operator is to move the jack with the shoe upon it into a position determined by the automatically operating breast gages, whereupon, by depressing the treadle,

28, the heel is moved into contact with the pre'sser plate, 10, and thereby automatically andinvariably presented in proper relative position to the cutter. The cutter, in its descent, trims the breast of the heel to the required amount and at a predetermined angle to the tread surface, and this stroke of the cutter is automatically limited, so that there can be no possibility of cutting too, deeply into the shank of the shoe sole.

- While a particular embodiment ofthe invention has been herein described, it is to be understood that the invention is not limited thereto,;but many changes may be made in of parts in this or other type of machine without departing from the spirit and scope of the invention. It is also. to be under- ,stood that the particular character of gages herein, selected for illustrative purposes are not intended as the only embodiment thereof, because various characters of gages which will determine the lateral swing of the shoe may be employed, and I desire it understood 'when' the term gage ,or gages is herein employed that it is intended in the broad sense.
