SPECIFICATION forming part of Letters Patent No. 650,871, dated June 5, 1900.
Original application filed December 7, 1899, Serial No. 739,565. Divided and this application filed February 19, 1900. Serial No. 5,749. (No model.)
To aZZ whom it may concern.- Be it known that I, CHRISTIAN SHIV'ELY, a citizen of the United States, residing at Carnegie, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and usefulImprovements in Rolls for the Manufacture of Tie-Plates, of which improvements the following is a specification. The invention described herein relates to certain improvements in rolls for the practice of the method described in an application filed December '7, 1899, Serial No. 739,565, of which application this case is a division. The method set forth in said application consists, r 5 generally stated,in displacing the metal along the middle portions of opposite sides of an ingot or billet, thereby forming two pairs of ribs projecting from opposite sides of the bar, and then bending or Working the ribs 011 one side outward and downward into the plane of the body portion of the bar.
The invention is hereinafter more fully described and claimed.
In the accompanying drawings, forming a 2 5 part of this specification, Figure 1 is a View in elevation of rolls having their passes constructed in accordance with my invention, and Fig. 2 is a similar View showing rolls having the final passes. 0 In the practice of my invention the passes of the rolls 1, 1, and 2 are formed by collars 3 on the roll 2 and by grooves 4 in the rolls 1 1, the bottoms of said grooves being formed by collars 5. The grooves 4 of the passes A B C D, or those in which reduction is most largely elfected, gradually increase in width and decrease in depth and have their side walls in planes at right angles or approxi mately at right angles to the axes of the rolls o 1 and 1. The collars 3 and 5 of these passes of the rolls are constructed and proportioned in accordance with rules well known in the art of roll-making for effecting the gradual displacement of the metal along the middle portions of opposite sides of the ingot or billet and the shaping and pro portioning of the ribs a and b, formed by the displacement of the metal. As it is desired to incline the side walls of the ribs b, the collars employed for producing and shaping said ribs have their side walls d inclined or beveled.
The passes E, F, and G,while effectin g some reduction, are designed more especially for bending or working the ribs a outward and downward to the plane of the body of the bar. 5 5 The groove 4 of the pass E, in which is effected the preliminary tendency, has the outer portions of its side walls flaring outwardly, and the side walls of the collar 3, which is considerably wider than the collar 5 of the preceding pass, are correspondingly flared.
Pass F is constructed to efiect a further bending or working down of the ribs a, but without materially changing the shape ordimensions of the ribs 1). In pass G the ribs a are brought into the plane of the body of the article, while the ribs Z) are maintained in the desired relation to the body of the article at right angles thereto.
It will be understood by those skilled in the art that the number of passes may be varied by increasing or diminishing the proportions of the operative portions of said passes. While the passes are shown as formed in the rolls for a three-high mill, they maybe formed, as will be readily understood by the skilled rolldesigner, in the rolls for a two-high mill.
