ROLL FOR MAKING HORSESHOE-BLANKS.

SPECIFICATION forming part of Letters Patent No. 470,353, dated March 8, 1892.

Application filed December 19, 1891. Serial No. 415,654. (No model.)

To all whom, it may concern.-

Be it known that 1, CHARLES HENRY PER- KINS, of the city and county of Providence, in the State of Rhode Island, have invented cer- 5 tain new and useful Improvements in Rolls for Use in the Manufacture of Toe-W'eighted- Horseshoe Blanks; and I do hereby declare that the following specification, taken in connection with the drawings furnished and I forming a part of the same, is a clear, true,

and complete description of my invention.

In my application for Letters Patent filed March 30, 1891, Serial No. 386,991, I disclosed certain novel bars containing toe-weighted- I horseshoe blanks in double lines, and the rolls devised by me for their production constitute the subject of my present specification. After describing my said rolls in connection with the drawings herewith the features deemed 2onovel will be duly specified in the several clauses of claims hereunto annexed.

Referring to the drawings, Figure 1 illustrates in front viewa pair of rolls, one of which is a die-roll constructed in accordance with my invention and adapted to produce specially-beveled blanks for use in making light or fancy shoes. Fig. 2 illustrates said die-roll in plane projection. Figs. 3 and 4 in like manner illustrate similar roll's adapted to produce plain toe-weighted blanks for heavy shoes j The roll A usually employed as a bed-roll has a plain guiding-groove a, considerably deeper than the thickness of the blank-bars 3 5 to be produced, but corresponding therewith in width. The die-rolls B and B possess in common certain characteristic features, and these will be first described. Each die-roll has a peripheral working face, which is enough 0 narrower than the groove a in the lower roll to enable said groove to freely receive a portion of the dieroll. Upon this working face there is a grooving-tongue, which is practically continuous on the periphery of the roll. Within the length of a blank said groovingtongue has a straight central portion b, which is parallel with the edges of the working face. This central portion 1) is quite short in the tongue of the roll B and of somewhat greater length in the tongue of the roll B, these varia- 4 tionsbeing incident to the differences between light or fancy shoes and heavy shoes. At both ends each central portion 1) is symmetrically branched or furcated, each branch b b b I) being straight, but inclined laterally toward the appropriate adjacent edges of the working face. The spaces between said edges and the outer ends of said branches are equal to the width of the narrower ends or heel portions of a blank, and the spaces opposite the central portion of the tongue are as wide as the wide central or toe portion of a blank. Each complete working section of the tongue is equal to the length of a blank, and it includes the central portion b and its four branches 1) b b b, and although a roll might have but one of these complete tongue-sections they are duplicated in the rolls shown, and the outer ends of each pair of branches unite with, the outer ends of another pair, the lateral parting-lines between them being indicated by suitable shallow cuts made by lateral parting-spurs 12 located at the j unctions of said outer ends. WVith this duplication of the tongue the roll during each rev0- lution will form four blanks in two rows or lines; but larger rolls having a greater number ofcomplete tongue-sections may be employed without departure from my invention. So, also, for working short lengths of metal may the die-rolls be employed with a sliding 1 grooved bed arranged to afford a suitable pass for the metal, although in no case can such a bed operate as advantageously as the grooved bed-rolls.

The double angular recessed spaces, as at c, which are inclosed by the branched portions 1) of the furcated grooving-tongue are here shown to have a depth equal to the projection of the grooving tongue beyond the plain working surface of the roll, and I prefer this arrangement as to depth because of the easy operation of such rolls. It will be obvious, however, that the bottoms of said spaces may be elevated more or less without in any man- 5 ner departing from my invention, inasmuch as it is the outer side only of each inclined portion b of the grooving-tongue that performs'duty in the formation of a blank. The two sides of each central portion 11 of the 10c tongue are in substance extended, and, being divergent or inclined outwardly in the branches 1), said extended sides will perform their duty just the same regardless of whether said portions b have any inner sides or not; but in proportion to the development of said inner sides the depth of said recess will be varied, and as its depth is lessened so will the bulk of waste metal between each pair of blanks be decreased; but that is a matter of little consequence compared with the greater ease and decreased wear and tear with which the rolls can be rapidly operated when the central portions of the bottoms of said recesses are substantially on a line with the plain portion of the working face of the roll, as shown.

As so far described the rolls B and B are substantially alike; but it will be observed that the several portions of the groovingtongue of the roll B have outer sides which are broadly and quite flatly beveled at the central portions 19, and from thence to the end of each outwardly-inclined portion 1) said bevel is gradually narrowed, as is clearly indicated. This broad beveling of the working faces or sides of the tongue is only desirable on rolls adapted to form blanks for fancy or comparatively light shoes. Now referring to the roll B, it will be seen that the central portion bof the grooving-tongue has working sides which are intentionally only so far beveled as will enable the tongue to be of sufficientstrength to form the division-groove between each pair of blanks, and the same is true of the portions 5 of said tongue. In both casestherolls are so set with relation to their oo-operating grooved rolls or other guiding support for'the metal that the grooving-tongue will cut sulficiently through the blank-bar to enable the two lines of blanks to be readily separated not only from each other, but also from the waste metal located between the blanks.

Both rolls B and B" are each provided with eight nail-head creasers or scorers d, all of equal length and each having four nail-head points 01, these creasers being appropriately located with reference to the straight-andinclined portions of the grooving-tongue adja-- cent to and parallel with the edges of the working face of the roll, and, while the best results will accrue from the use of rolls provided with these creasers, it is to be understood that they may be omitted without departure from the main feature of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Paten't l. A die-roll, substantially as hereinbefore described, for forming blank-bars containing two lines of toe-weighted-horseshoe blanks, said roll having a working face provided with a grooving-tongue, which within the length of a blank has a central portion which is substantially parallel with the edges of the working face, and which at both ends of said central portion is branched or furcated, each branch being inclined toward the adjacent edge of said working face.

2. A die-roll, substantially as hereinbefore described, for forming blank-bars containing two lines of toe-weighted-horseshoe blanks, said roll having a working-face provided with a grooving-tongue, portions of which are centrally located at intervals and are parallel with the edges of the working face and are branched at both ends and inclined toward the edges of said face, each central portion and its four outwardly-inclined portionsbeing within the length of a blank.

3. A die-roll, substantially as hereinbefore described, provided on its working face with nail-head creasers and also with a groovingtongue, which within the length of ahorseshoe-blan k consists of one central portion parallel with the edges of the working face and four branched or outwardly-inclined portions.

4. The combination, with a 'roll provided with a guiding-groove, of a die-roll having a working face adapted to enter said groove and provided on said face with a grooving tongue, which within the length of ahorseshoe-blank consists of one central portion and fourbranched or outwardly-inclined portions, substantially as described, said rolls being adapted to produce blank-bars containing two lines of toe-weighted-horseshoe blanks.
