HERMAN J. HUISKAMP, OF FORT MADISON, IOXVA.
HEEL-TRHVIMING MACHINE.
TJPEJEFICATIQN forming part of Letters Patent No. 324,844, dated August 25, 1885.
(No model.)
To aZZ whom, it may concern.-
Be it known that I, HERMAN J. IIUISKAMP, of Fort Madison, in the county of Lee and State of Iowa, a citizen of the United States, have invented a new and usefulImprovement in Heel-Trimming Machines, of which the fol lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification in explaining its nature, in which? Figure 1 shows my invention applied to a portion of the heel-trimming machine known as the King heel-trimming machine, shown and described in Letters Patent No.-2(i7,54t, dated November 14, 1882. Fig. 2 is an enlarged sectional View of a portion of the cutterhead guide and cutters with a bootheel in position to more clearly show the construction and operation of my improvement. Fig. 3 represents in perspective the shape of the knife, which constitutes the especial feature of my invention. Fig. 4 is aseetiou upon the lines: 00 of Fig. 3. Fig. 5 isa View in rear elevalion of the gage -plate, representing a guide and guard having a lip which partially covers the point of the finishing-knife. Fig. (i is a -view in elevation of the feathering and trimming knives.
The object of the invention is to provide means for what is commonly known asfeatheredging the heel-that is, the removal of a slight skiving from the upper edge of the heelportion of the outsole-in order to provide a form of finish which is at the present time much in vogue.
All the parts which are shown in the drawings, with the exception of the leather-edging knife and the removable guide and guard, hereinafter described, and the variations in the form of the heel-shaving knife, also hereinafter specified, are the same as those described in. the said Patent No. 267 ,544.
Referring to the drawings, A is the cutterhead, having the shaving knives or cutters, which are positively revolved,and are secured tothe head andprovided. with the adjustments as described in said patent. Bis a portion of the jack which permits all necessary adjustments of the boot or shoe heel in relation to the cutters, and is the same as that described in said patent. G represents what is called the gage-plate in said patent. As, however,
my invention contemplates not only the trimming of the heel, but also the trimming ofthe upper edge of the sole about the heel, it is necessary that the gage Oshould be somewhat differently constructed from that of the pat ent. Before describing this difference I will describe the feather-edging or sole edge-trimming knife and the way which I prefer to secure it to the cutter-head.
The best illustration of the knife is that found in Fig. 3 of the drawings; and it comprises a flat plate, I), having on one edge a backward extension, d, in the form of a halfdovetail, between the lower portion, (2, of which and the back of theknife or plate is the groove or recess d, which receives the projection (1, also in the form of a half-dovetail, on the trimmiligknifc D, and the section (1 also closes into a recess in the edge of the knife D. In other words, the plate D is locked to the knife D by a halfdovetail construction,whereby one portion of one plate overlaps a portion of the other plate, so that the two knives or plates are held firmly together. Extending forward from the outer edge of the plate D, in line with the extension (I, is the sole-edgeskiving knife (1. Thisknife extends toa point, 61", and has the cuttingedge (1 extending back therefrom, having the bevel surface (1 and the cutting edge of this sole edgeskiving knife, when in use, projects slightly in advance of the cuttingedge d of the heel-trimming knife 1).
Both the plate D and the knives D have a slot, (1, of the same size, location, and shape, so that both plates may be fastened to the cut ter-head by one bolt; and the plate D is ar ranged to slide in relation to the knife D, so that as the cuttingedges of the knives wear they may be adjusted in relation to each other, or the sole-edge-skivingknife may be adjusted in or out in relation to the cuttingedge of the heel-trimming knife, or may shave narrower or wider skivings from the soleedge, as may be required or desirable.
In order that the point of the sole-edgeskiving knife may not come in contact with the upper and. inj are it, Ihave arranged upon the edge of the gageplate G the lip c, which extends slightly downward from the removable plate a, forming a part of the gage-plate and fastened to it by the screws 0'. This lip ICO also projects outward from the inner edge of the gage-plate to cover the point of the knife (1. In use this lip enters, or partially enters, the space between the sole-edge and the lower portion of the upper, and it thus answers not only as a protector or guard, but also as a guide in governing the presentation of the sole-edge, as well as the heel, to the trimming-knives.
I form the lip upon the removable plate 0, instead of upon a gage plate, as it will be necessary to remove them from time to time as they are worn out and substitute others; also because of the necessity of changing the form and depth of the lip from time to timeto adapt the machine to different styles and varieties of work.
It is not necessary that there be more than one sole-edge skiving or feathering knife on each cutter-head.
.Of course I do not confine the use ofthis invention to the machine described, but intend to employ it on any heel-trimming machine having rotary cutters.
In operation the heel is presented to the cutters in the same manner as it is to the cutter of the King rotary machine, and the heel is not only trimmed upon its vertical edge, but its upper edge is also beveled.
Having thus fully described my invention I claim and desire to secure by Letters Patent of the United States 1. In a heel -tri1nming machine, the combination of the blade or cutter D with the plate D, supporting the edge skiving or feathering knife, all substantially as and for the purposes described.
2. The combination, in a heel-trimming machine, of a rotary shaving knife or blade, D, and the plate D, adjustable upon the knife D and supporting the sole-edge skiving or feathering knife (1, all substantially as and for the purposes described.
3. The combination of the shaving-knife D and the sole-edge skiving or feathering knife plate interlocked by the half-dovetail d d, as described, all substantially as and for the purposes set forth.
4. In a hee1-trimming machine, the feathering-knife (1", having the cutting edge 01 and the bevel surface 01 all substantially as and for the purposes described.
5. In a heel-trimming machine, the combination of the gage-block G with the removable guard or gage plate 0, all substantially as and for the purposes described.
