METHOD OF AND APPARATUS FOR MANUFACTURING BLANKS AND BLANK-BARS FOR SIDE-WEIGHTED HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 470,365, dated March. 8, 1892.

Application filed August 7, 1891.

To all whom it may concern.-

Be it known that I, CHARLES HENRY PER- KINS, of the city and county of Providence, and State of Rhode Island, have invented a certain new and useful Method of and Apparatus for Manufacturing Blanks and Blank- Bars for Side-Weighted Horseshoes; and I do hereby declare that the following specification, taken in connection with the drawings lo furnished and forming a part of the same, is a clear, true, and complete description of my invention.

In my application for Letters Patent tiled May 9, 1891, Serial No. 392,209, I disclosed i 5 various forms of bars containing blanks for side-weighted horseshoes, and I therein expressed preferences for such bars' as contain the blanks in double lines as compared with those in which the blanks are in a single zo line.v I have now, howevei, practically demonstrated that in rolling single-line blankbars atwise and laterallydisplacing the waste metal the slight excess of scrap or waste as compared with that involved in double-line rolling is practically of little consequence, because of a minimum of destructive wear on the die-roll and the high speed at which the bars can be produced. Moreover, in the flatwise single-line rolling each blank is formed 3o in as perfect condition as when rolled in double lines, and with proper variations in the grooving or displacing tongue of the dieroll portions of the metal which would otherwise be waste or scrap maybe readily utilized in the formation of reinforcing projections at various portions of the shoe. In the matter of scrap or wastemetal I further nd that it will bewell reduced by first rolling stock-bars of a thickness substantially equal to or but 4o little greater than the blanks desired and forming thereon a liberal bevel at one side and edge. When the die-roll operates flatwise on the bar so beveled, the tongue or edge "cutting and displacing portion of the roll in forming the blank worksadjacent to the b eveled line and the small bulk-of `metal which is laterally displaced in producing each blank involves a minimum of destructive labor by the tongue of the roll` It is to be understood,

Serial No. 402,007.` (No model.)

however, that although the beveling of the 5o stock-bar is of great practical value I do not restrict myself thereto, inasmuch as the main feature of my present invention consists in first rolling a fiat straight stock-bar of suitable sectional area and then iiatly rolling said 5 5 bar and laterally displacing the metal thereof at one edge to a degree variably corresponding to the varying width of the consecutive blanks. The forming of the nail-head creases simultaneously with the shaping of the blanks 6o will of course be always preferable to subj ecting the blanks to a subsequent operation ;V but this latter procedure may be practiced with satisfactory results if the shaping of the blanks be first performed, as described, this latter being `the most important operation.

After describing my improvements in detail in connection with the drawings, the several features of my invention will be designated in the appropriate clauses of the claim hereunto 7o annexed.

Referring to the drawings, Figure 1 illustrates in bottom or tread view a pair of side- Weighted horseshoes embodying blanks from blank-bars produced in accordance with my present invention, dotted lines indicating certain desirable variations in the distribution of metal. Fig. 2, in bottom or tread side view, edge view, and in several sections, illustrates a blank-bar containing such blanks as are em- 8o bodiedin shoes shown in Fig. 1. Fig. 3 in similar views illustrates a blank-bar differing from that shown in Fig. 2 in the matter of affording a specially-beveled inside edge in the shoes formed therefrom. Fig. 4 illustrates in 8 5 front view a set of rolls affording passes for i two forms of stock-bar and a die-roll pass for the single-line blank-bar, Fig. 2. Figs. 5 and 6 in side view and cross-section, respectively, illustrates plain and beveled stock-bars.

Th e first step in the production of the blankbar A of Fig. 2 or A of Fig. 3 is the rolling of a stock-bar of suitable sectional form and area. The stock-bars are substantially fiatsided and straight-edged and a little thicker 95 and a little wider than the blanks desired. For the production of the blank-bar in both forms, Figs. 2 andf, the stock-bar may be substantially rectangular in crosssection,as with the stock-bar B of Fig. 5; but substantially valuable results accrue by beveling it at-one side and edge, as at ct, on the stock-bar B', Fig; 6. The second step in the production of the blank-bars A and A is the rolling of a suitable stock-bar fiatwise and laterally displac- 2, or the blanks b2 bsin the blank-bar A', Fig. 3. It Will noW be observed that these differently-designated blanks in the blankbars, Figs. 2 and 'L-although end to end in one line,l

are respectively rights and lefts, a right blank b being used in the appropriately-designated shoe C of Fig. l, vand the left blank b in the shoe C. "Each blankH is thereforeof substantially uniform Width` for a portion=of its length and tapered throughout the remainder of .its length.v One edge of the blank is straight throughout itsllength,:as at c, this ed elbeinga .portion of the .corresponding straightzedge of .theblank-bar, butv more symmetricallyrdeveloped. `At `the opposite orspeci'ally-shapedfedge one portionl is straight andparallel with. the adjacent'edge of the f roll, asa'tcand theother isf-inclined, as `at c2,..thus. affording in ythe shoea Wide toe, a

wideside-.and heel, anda .narrow side and# heel. t ln the 'forming' of the specially-shaped edge/c. c2, provisionis made for varying the linear andsectional contour of the lshoeatll its innerA edge, two such varia-v tions being illustrated. by the` obvious differencesY between .the .narrowy and Wide "bevels of they-blanks inthebars of Figs. 2 and-3, and

furtherv differences. are indicated bydotted lines inthefshoes of Fig. l,aswill be hereinafter. again-referred to. Will obviously accrue if during the rolling and shapingof theblank-bar 4the nail-head creases CZ are simultaneously formed/auditis at leastdesirableat the sameztime tokmake endgparting cuts `or scores, asatle, although these lmay bezdispensed'with` Wholly by rely-` l ingupon-Aproperly-gaged. cutting-shears for 1 theendwise separation of the blanks. The nail-creases din each blank are inlinewith eachother and closely adjacentY to and paralleljwithV the-.straight edge c of the blank. Thescrap or .Waste metal blank-barsA and Aare usually soy far severedfrom the blank-bar as to admitot their readyremovah l ,.1 v

Referring now 4to `Fig. 4 it Will be-understood thatthe several roll-passes D, D and E used by me maybe afforded by a :group ofrolls y.mounted inv onef'housing or mountedseparately, it .being preferable, however, that the die-rollE- and its-co-operating grooved :roll E? should constitute a. separate organizationrconfveniently.adjacent to: the Vstock-bar rolls.Y The pass D- is afforded by rolls g and g', which' are of the plain:y ordinary tongueand-groove type, for rolling. the stock-bar B ing wastemetal at one side ofthe bar to anv extent corresponding'to the varied Widthv 'of' each blank b and b in the blank-bar A, Fig.V

vtional contours of varying j the'- displacementof metal, and `correspondingly .The .best results piecesj' and f of the of Fig. 5. The roll h at the pass D is a plain tongue-roll, the grooved roll h having at one side an upwardly-inclined annual bevel, as at h2, for rolling the stock-bar B of Fig. 6, With its bevel a at one side and edge. The die-roll E has a face which Iat its Widest point at t' is-as f Wide as the Widest portion of the tread side of L blanlQ-and at if theface corresponds-in Width withA the tapered or narrowest 'por-tion of a blank,"and a grooving or displacing tongue 7.: defines one edge of said face, said tongue bei in gstraight and parallel with the adjacent end of the roll at intervals, as at t', but inclined toward the 'opposite edge ofthe face, as 'at i", and then it is reversely inclined from said edge back to the succeeding straight portion at the rear side of the roll opposite to that shown inthe drawings. "This groo'ving or displacing tongue k is `varied in its cross-sectional contour according to the particular form in which the inner edge of asloe'inay be desired, and its contour in1 this instance can be readily determined by .thevarious secthe scrap*v `metal f of Fig. 2

andthe variableshap'e'of the groove inter-4 venin-g'betweenit and the blanks.

I vhaved'evised a diepjroll'- for producing double-line blank-bars,iand the same constitutes the subject of a separate applicationforl Letters-Patent, (see Serial'N o. 401,758) said rolls-differing materially lfrom the die-roll E herein shown', the characteristic feature Yof. Which is a grooving-tongue located, mainly' lnear one edge of the roll and 'parallel ltherewith, and Which-is lat intervals inclined to- Y ward and from the opposite edge of the roll.

The roll E2 may be an ordinary solid grooved roll, or-the groove may be afforded by two mov# or one stationary andthe other' able collars, movable and adjustable in a manner Well known, and in either eventthe groove or pass should beatrifle widerthan thegstock-bar to be used, and also so that the-straight or non-inclined portion of the-displacing-tongue 7c will occupy aline Well Within the plane occupiedV `by the adjacent side of the pass'E,vthu's affording space for the free displacement of the metal at the narrowest or lightest parts of the scrap-piecef. For forming the blanksfor the shoes, Fig. 1,-thegrooving or displacing tongue 7c is quite steep and but slightly beveled on IIO the side next to the face of the'roll; but on the outer sidev it is variably'beveled', the tongue being alike on both sides portions at t', andat the inclinedportion it is widely beveled on the outer side,v as clearlyin'- along the straight dicated inthe appropriate sectional View lof the` blank-bar A. The beveled surface of the tongue at its inner side next to the face of the rollis materially enlarged or widened for provlducing the-blank-bar A but the outer side'is provided withv a minimum and uniformbevel.v

-It will be seen that there is ample space afpforded' by the groove of the roll E2 (or pass E) for accommodating the-Waste metal which Iis laterally displaced from the plain stock-bar,

`-andthat with the beveled stock-bar B there is even still more space afforded for the Waste metal and that the weight of the latter will be lessened to the extent of the reduction in the cross-sectional area of the scrap-piece due to the bevel, and in working such beveled stockbars the edge of the portion of the tongue 7c at t' can occupy a line along the stock-bar adjacent to the junction of the tlat top surface and the beveled surface. The nail-head creasers d are appropriately located parallel with the end of the roll farthest from the tongue 7c, and in some instances the creasers will be continuous; but they Will always afford the special depressions or head points in the creasers, andthey will be varied in number, but usually, as shown, with four head-points at the Wide side and three at the narrow or lightside of the shoe. By thus working the blank-bars by flatwise-rolling and with the blanks in a single line it will be seen that for producing certain special forms of sideweighted shoes the tongue has only to be correspondingly varied-as, for instance, the narrow heels of the shoes can be broadened, as indicated in dotted lines, thus lessenin g waste and increasing the tread area at the heel with-v out materially changing the side-weighted character ot' the shoe and to some extentlessening waste. Again, by imparting an outward curve to the tongue 7c adjacent to the junction of the Wide and narrow portions it will takein some of the otherwise Waste metal and increase the width of the` shoe, as indicated in dotted lines in Fig. l, at the toe, and thereby also increase its front weight.

It has been stated that in both of the'blankbars shown the blanks are consecutively rights and lefts, and it will be obvious that when the Wide end of one blank abuts in the same bar against the narrow end of the next blank in line the blanks will either be all letts or all rights, and while such bars are less desirable than those shown, the method described would be employed in producing all of them, and the die-rolls would be the same to the extent that each Would essentially have a grooving and metal-displacing tongue partly parallel with one edge or face of the roll and partly inclined toward the opposite edge.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The method or process of manufacturing bars containing a single line of blanks for side-weighted horseshoes, which consists in first rolling a flat straight-edged stock-bar of suitable area in cross-section, and then rolling said bar iatwise and forming one edge of the consecutive blanks by laterally displacing the metal at the corresponding edge of the bar to an extent corresponding to the Variation in the width of each blank, substantially as described.

2. The method or process of manufacturing bars containing a single line of blanks for side-Weighted horseshoes, which consists in rolling a straight-edged stock-bar of appropriate sectional area and beveled at one side and edge, and then rolling said bar iiatwise and variably forming one edge of the consecutive blanks by laterally displacing the metal at the beveled side and edge ot' the bar, substantially as described.

3. The method or process of manufacturing bars containing a single line of blanks for side-Weighted horseshoes, which consists in first rolling a flat straight-edged stock-bar and forming appropriate nail-head creases simultaneously with rolling said bar flatwise, and shaping the consecutive blanks by laterally displacing metal at one edge of the bar to an extent corresponding to the varied Width of the blank, substantially as described.

4. A die-roll for forming bars containing a single line of side-weighted-horseshoe blanks, provided with a grooving-tongue, which is located mainly near and parallel with one edge of said roll and is also inclined toward the opposite edge, said roll being adapted, substantially as described, to operate atly upon a stock-bar of metal for shaping one edge of consecutive side-Weighted-horseshoe blanks, and laterally displacing Waste metal at one edge ot1 the bar.

5. A die-roll for forming bars containing a single line of side-weighted-horseshoe blanks, provided with a grooving-tongue, which is located mainly near and parallel with one edge of the roll and is inclined at intervals toward and from the opposite edge of the roll, and is also provided with appropriate creasers for forming nail-head creases in the blanks, substantially as described.
