MACHINE FOR BREASTING- I-IEELS.

To all whom it may concern:

Be it known that I, JOSEPH GoULnBoURN, a subject of the King of England, residing at Leicester, in the county of Leicester, England, have invented certain Improvements in Machines for Breasting Heels, 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 fo breasting heels. l

The present application constitutes a division of an application iiled July 10, 1906, Serial No. 325,516.

The machine shown herein comprises a Work support for sustaining a heel in position to be acted upon and a cutter arranged for movement along the face to be trimmed. Mechanism is provided for guiding the cutter in a predetermined path across the breast of a heel, and the arrangement is such that the breasts of heels may be trimmed to various contours by adjustment of the ma.- chine. The construction herein described is such that the contour produced may be either concave, convex or straight, and the degree of conveXity or concavity may be varied as desired.

The particular construction shown herein comprises a work support, a movable cuttercarrying member, and mechanism for controlling the movement of said member, adapted to cause two separated points on said member to have a simultaneous'traverse along paths which are straight and angularly disposed to each other. It will be found that by suitably locating the cutter upon its supporting member the path of the cutter may be made convex or concave with relation to the breast of the heel, or, if desired, may be rectilinear to give the breast of the heel a straight contour. To permit the depth of cut of the cutter to be variedas desired, the work supporting member is arranged for adjustment to permit the work to be moved into or out of the range of the cutter.

Other features of the invention, including details of construction and combinations of par-ts, will be hereinafter described and defined in the claims.

In the drawings,-Figure 1 is a side elevation of part of a heel-breasting machine Specification of Letters Patent.

Patented Aug. 23, 1910. Divided and this application filed October Serial No. 395,904.

showing the present invention wherein the heel is stationary and the cutter is mounted in bearings supported upon a movable member or plate; F ig. 2 is a front elevation of the parts shown in Fig. 1; Fig. 3 is a sectional view of the cutter, member or plate, and adjacent parts on the line 3--3 of Fig. 1; Fig. 4 is a sectional detail view on the line 4-4 of Fig. 1.

Referring to the drawings, in the construction illustrated therein a heel carrier 12 is mounted directly upon the machine frame 13 and a rotary cutter 14 is carried by a controlling plate 16 provided with a handle 18 by means of which it may be moved by the operator to bring the cutter into engagement with and to cause it to travel past the heel 20 to effect the breasting of the same. The path of motion traversed by the cutter is controlled by two

rollers

22, 24, mounted upon the

studs

26, 28 screwed into the controlling plate, which rollers engage respectively with two

cam grooves

30, 32 formed in the machine frame. To retain the controlling plate in position on the machine frame it has three lugs 34, which engage respectively with surfaces 36 and overhanging flanges 3S formed upon the ma chine frame 13.

With the parts adjusted as shown, the operation of the machine is as follows The handle 13 is moved downwardly causing the controlling plate 16 first to swing about the roller 24 on the stud 2S as a center while the roller 22 on the stud 26 is traveling along the curved part of the cam groove 30 thus bringing the cutter into engagement with the corner of the breast of the heel. A continued downward movement of the handle 18 neXt causes the rollers to travel along the

grooves

30, 32 and thereby so guide the cont-rolling plate that the center of the cutter travels in substantially a straight line and consequently thecutter is caused to breast the heel with a straight cut.

Vhen it is desired to give a concave curvature to the breast of the heel the cutter is adjusted to a position o-n the controlling plate 16 nearer to the

grooves

30, 32 than that in which it is shown in Fig. 1. But this adjustment of the cutter will necessitate an adjustment of the position of the heel carrier 12 on the machine frame; otherwise the cutter will be too far within range of the heel 20. In order that these adjustments may be readily obtained both cutter and heel carrier are adjustably mounted upon the parts that support them. The heel carrier 12 is provided with a heel-clamp 15, pivoted at 17 to the carrier 12 and having its free end adapted to bear by way of a contact piece 19 upon the seat of a heel 20, the top lift of the latter' resting upon the carrier 12. The clamp is operated by the adjustable link 21 connected to it at 23 and also connected to the carrier. This heel carrier is mounted in guideways 40 on the machine frame and is provided with an adjusting device 42 comprising a. screw engaging a screw-threaded lug on the machine and connected to the carrier by a pin and groove connection. The cutter is secured to a shaft 44 carried in bearings on a slide 46 mounted in guideways in the controlling plate.

An adjusting device 48, similarl to the device 42, is provided to enable the slide 46 and cutter 14 to be adjusted on the controlling plate. The cutter is driven from any suitable source of power by a belt eX- tending over a pulley 52 fast upon the shaft 44, any usual belt-tightening device being employed to obtain the desired tension of the belt on the pulley 54 during the movement of the cutter. It will be understood that if it is desired to impart a convex curvature to the breast of the heel the cutter 14 will be adjusted to a position farther from the

grooves

30, 32 than that in which it is shown in Fig. 1.

The path of relative motion of the heelcarrying member and the cutter-carrying member obviously may be controlled by cam slots other than those shown; for instance, three slots of a similar shape to the lugs 34, Fig. 1; but to enable the heel to be breasted to any curvature from that of the cutter to a straight line or even a convex curvature, these slots must be arranged so that two points-for example, 26, 28-on the cuttercarrying member move in paths which are straight and angularly disposed to each other or are non-concentric- Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A heel-breasting machine having in combination means for sustaining a heel to be acted upon, Va cutter movable from side to side of the heel, and mechanism for guiding thecutter in a predetermined path, said mechanism being arranged for adjustment to permit said path to be either straight or curved.

2. A heel-breasting machine having in combination means for sustaining a heel to be acted upon, a cutter, and mechanism for guiding the cutter in a curved path from side to side of the heel, said mechanism being arranged for adjustment to permit the direction of curvature of said path to be varied.

3. In a machine of the class described, the combination with a cutter-carrying member and a heel-carrying member arranged for relative traversing movement, of mechanism for constraining two separate points on the cutter-carrying member along paths.- which are straight and angularly disposed" to each other.

4. A machine for trimming heels having in combination means for sustaining a heel to be acted upon, a cutter movable along the face to be trimmed, and mechanism for guiding the cutter in a predetermined path, said mechanism being arranged for adjustment to permit said path to be either straight or curved.

5. A heel-breasting machine having in combination means for sustaining a heel to be acted upon, a rotary cutter arranged for movement from side to side of the heel, and means for guiding said cutter arranged to vary its path whereby to impart a straight or curved contour to the breast of a heel.

6. A heel-breasting machine having in combination a frame, a work support thereon, a movable controlling member carrying a cutter and means for guiding said member to impart to the cutter a movement in a predetermined path relatively to the work support, the cutter being arranged for adjustment relatively to said means whereby the direction of curvature of said path may be varied.

7. A heel breasting machine having in combination a frame, a work support thereon, a movable controlling member carrying a cutter, means for guiding said member to impart to the cutter a movement in a predetermined path along the breast of a heel carried by said support, means permitting adjustment of the cutter relatively to said means to vary said ath, and means permitting adjustment of the work support to maintain it in proper relation to the cutter.

8. A heel breasting machine having in combination a frame, a work support thereon, a movable controlling member carrying a cutter, mechanism comprising angularly disposed grooves and studs tting said grooves arranged between said frame and controllin member for guiding said cutter in a pre etermined path relatively to the work support, and means permitting adjustment of the cutter relatively to said mechanism whereby to vary said path.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
