CHARLES H. TRASH, OF LYNN, MASSACHUSETTS.
BOOT OR SHOEHEEL TRIMMING MACHINE.
SPECIFICATION forming part of Letters Patent No. 357,739, dated February 15, 1887.
Application filed June 15= 1886. Serial No. 205,202.
To @ZZ whom, it may concern:
vBe it known that I, GHAELEs H. T1msn, of Lynn, in the county of Essex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Boot and Shoe Heel Trimming Machines, of which the following is a full, clear, and eX- act description, reference being had to the ac companying drawings, forming a part of this specification, in explaining its nature.
The invention is an improvement upon that described in my application for Letters Patent of the United States, filed June 7, 1886, Serial No. 204,324; and it relates especially to the heel trimmer or cutter, to the heel-rest, to the top-lift guide, and to the rand-cutter.
Referring to the drawings, Figure 1 is aview chine containing the features of my invention. Fig. 2 is a view in front elevation thereof. Fig. 3 is a sectional view upon the line x ai of Fig. 2. Fig. 4 is a View in elevation of the part forming the toplift guide and connections, to which reference is hereinafter made. Fig. 5 is aview in section upon the line x x of Fig. 3 in elevation of the parts in front of said Fig. 6 is a vertical section-of the heel ltrimmer or cutter, rand-knife, rand guard or guide, and end ofthe operative shaft, illustrating a modified form of the invention. Fig. 7 is an elevation of the cutter in front. Fig. 8 is a rear elevation of the cutter. Fig. 9 is a view in elevation to represent the cutter and the relation which the top-lift rest and guide bears to it, and also representing the manner in which the top-lift rest and guide is automatically moved and adjusted to conform to the varying curvature of the cutter as it is moved in and out. Fig. 10 is a plan view to further illustrate this feature of my invention. Fig. 11 is a detail view of the same.
Referring to the drawings, A represents the sole-edge and welt-trimming cutters. They are like those described in my said application, are protected as therein described, and are supported upon a shaft substantially as therein specified.
B is the shank-edge trimmer and welt-knife. They are like those described in said application, are mounted upon their operative shaft, and rotated and protected as therein specified.
(No model.)
C is the heeltrimming knife; but instead of being in two parts or sections, as described in said application, it is asolid cutter made from a solid block of metal, which is turned or shaped to provide its circumference or surface with the desired curvature from the rear surface, c, to the front surface, c. Of course the curvature or form of this circumference varies according to the style which it is desired the edge surface of the finished heel shall have. This blocl; has formed in it a hole, c2, for the reception of the shaft, and a keyway, cf. It also has cut from its surface or circumference inward the tangential recesses c4, which provide or forni the cutting'edges c5 of the knife. The openings or recesses c* are of sufficient width to permit the cutting-edges to reach the heel edge and operate thereon, and also to provide a proper clearance for the chips or pieces f stock removed from the heel; and these recesses are preferably further formed or shaped to increase in depth gradually from the front to the rear of the cutter, so that they shall be longer at the rear than at the front and provide an inclined bottom or end, c, upon which the chips or pieces of stock removed by the cutters shall be removed as the cutter is revolved, to be finally expelled at the rear of the cutter. The sections cT of the eutter, or those parts between the rear cuttingedge and the entrance to the recess c1 next adjacent, preferably have the same curve or shape-that is, they form parts of the circle upon which the cutter is struck. This cutter possesses advantages in that it is strong, cheaply made, is easily sharpened, as it is only necessary to grind the surfaces cS on a flat wheel, and produces a very smooth and uniform result or finish.
The cutter is mounted upon its shaft C so as not to obstruct the passage or throwing off of the waste through the recesses c. This is accomplished by forming the shaft with a shoulder, b, against which the cutter is held in any suitable way. The length of the cutting-edge of the cutter preferably is longer than the longest cut which it is desired to make upon the heels, for which it is especially made; and in order that the heel maybe properly guided or presented to the cutter, and so as to obtain a longer or shorter cuttingsurface of the heel first presented to it. The heel is then turned upon the rest E, and as it is turned the length presented to the cutter varies and the top-lift guide and guard is automatically moved backward by the work and returned by the spring, the heel-rest moving with it, so that greater or less lengths ol' the cutting-surface of the cutter are brought into action at the proper time, the extent of such operating-surface being entirely governed by the length of the eut which it is desired to make on the heel. r
The point or projection di, which extends from the top-lift rest and guide-arm d and which bears against the cam or incline d8, is made adj ustable in relation to the said arni d, and I have shown it in the form of a screw, the rounded end of which forms the projection, as this is the simplest and easiest way by which this adjustment can be obtained. The inclined surface d8 may be in the form of a recess or slot cut in the arm D', as shown in Fig. 3, or it may be formed upon a block attachedv to the arm D2, as shown in Figs. 9, 10, and ll, and when this form of construction is used I prefer to give the block an adjustment in relation to the arm D2 by pivoting itat h to the arm D2 and by the adjustingscrew 71,', which is arranged to bear against the end of the block l1, to move it in and out, and in that manner govern the slope or inclination of the surface d.
Many of the details of the construction shown and described are contained in my sim ultaneously-pending applications Nos. 205,203 and 205,204, and the parts and combinations claimed herein are not claimed in them, and the parts and combinations claimed in them are not claimed herein.
I reserve the right to make the cutter herein described the subiectmatter of another application.
Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesd l. In a heel-trimming machine, a top-lift rest and guard adapted to cover a portion of the surface of a rotary heel-cutter and to be movedby the work in one direction and by a spring in a reverse direction, with a cam or guide for go verning the direction of said movement and maintaining it parallel to the eutting-edge of the cutter, substantially as specified.
2. In a heel-trimming machine, the combination of a rotary cutter with a top-lift rest and guide adapted to cover part of the surface ofthe rotary cutter and to be movable in one direction by the work and in a reverse direction by a spring, and a guiding surface or cam for governing the direction of its movement in relation to the surface of the cutter, substantially as specied.
3. The combination of a rotary cutter, a toplift guide, guard, and rest, D D', formed upon the ring d, the arm di, having a sleeve, d, the post d, the guide di, and the springs d" dl, substantially as described.
4. In a heel-trimming machine, the combination ot' a rotary cutter, a heel-rest, and a toplift guide and restsimultaneously movable by means, substantially as described, in the same direction transversely the plane of rotation of the cutter and parallel with its cuttingedge, substantially as described.
5. The combination, in a trimmingmachine, of a rotary cutter, a rest, E, movable transversel y the plane of rotation of the cutter by the work in one direction and by a spring in the reverse direction, and a guide or cam for maintaining the heel-rest at the saine relative distance from the edge of the cutter as it is moved, substantially' as described.
6. The combination of the rotary cutter C, the cutter-shaft C', the rand-guard, the randknife having the enlarged hole, and the bolt, stud, or other device for locking them against the cutter and to the shaft C', substantially as described.
7. The combination of the rotary cutter, the rotary rand-knife having the enlarged hole g, and the rotary rand-guard, the rand-knife being movable in relation to the cutter and rand- ,guard, substantially as described.
