SPECIFICATION forming part of Letters Patent No. 448,073, dated March 10, 1891.
Application filed J une 26,1890.
To all whom, it may concern: Be it known that I, JAMES M. PRICE, a citif zen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Imp rovement in Rolling-Mills, which improvement is fully set forth in the following speciication and accompanying drawings.
Myinvention consists of a machine for molding plate metal in the'form of a series of truucated pyramids, the heads whereof are flat or level in one plane and the feet whereof are flat or level in another plane parallel with the former, but removed from the same by intervals, the product being serviceable Jfor crossties, stringers, trusses, the.
Figures l and 6 represent partial side elevations and partial vertical sections of molding-machines embodying my invention. Fig. 2 represents a top or plan view thereof. Fig. 3 represents a side elevation of a detached portion thereof. Fig. -i represents a section of the product or work on line a; at, Fig. l. Fig. 5 represents a side elevation at a right angle to Fig. G. Fig. 7 represents a side elevation of a portion ofFig. 6. Fig. 8 represents a section of the product or work on line y y, Fig. 6.
Similar letters and numerals of reference indicate corresponding parts in the several figures.
Referring to the drawings, A and B designate rolls which are mounted upon suitable housings having on the sides thereof the wheels or rims C, of different diameters, and having peripheries with concentric segmental circular toothed racks or gears A B, which are located at intervals on the peripheries alternating on opposite rims, forming mutilated gearing. IYithin the rims are dies D, which are of the form of truncated pyramids D', projecting from the rolls A and B, and faces D2 between said pyramids at intervals, so that the anvils of one roll enter the intervals between the anvils of the other roll, and the heads of the -pyramids D of one roll are adapted to pass the faces D2 of the opposite roll, a space for the metal exist-ing between the heads, faces, and sides of opposite anvils, as will be most clearly seen in Fig. 1, it being noticed that the heads of the Serial No. 356,758. (No model.)
pyramids D and the faces D2 meet in the same plane, they being, as is evident, of different diameters.
It will be seen that when power is imparted to the rolls the gears of adjacent rims successively engage and disengage, imparting intermittent motions to the anvls. As the metal passes between a pair of associate dies it receives alternate speed or rate of motion, according as its face emerges from contact with said dies, and the parts D of one die force the metal against the parts D2 of the other die, thus crimping or bending the same into undulating form or the form of truncated pyramids in reversed order, or with heads 1, sides 2, and bases or feet 3.
VThe dies may be one, two, three, four, or more in number to each roll, according to convenience or purposes of dimensions required. The surfaces of the molds may be iiat or straight in transverse direction, or slanted, or they may be grooved on the edges and sides in order to form flanges on the cross-pieces, stringers, trusses, ttc., as will be seen in Figs. 5 and S.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. A pair of rolls with dies for shaping metal into a series of undulating truncated pyramids connected at base, and with heads and feet in parallel planes, substantially as described.
2. A pair of rolls formed with one or more dies curved circularly on their outer faces and projecting from a crculardie of smaller diameter.
3. A pair of rolls embraced or confined between two concentric toothed rims of different diameters adapted to drive reciprocal rims or wheels upon or attached to the opposing roll, substantially as described.
4. A pair of rolls confined between two concentric toothed rims of diverse diameters, of which for each so many teeth shall have been omitted or removed as shall permit the one pair of wheels attached to the driving-axle so to engage and disengage the opposing pair as to produce harmony of action, regardless of the difference of diameter, substantially as described.
o. The alternate engagement and disengagement of two pairs of toothed wheels or rims, of diverse diameters, interlocking the large with its small opponent, said rims having mutilated gearing, substantially as described.
G. Toothed rims or wheels provided with mutilated gearing and in pairs of different diameter, interlocking the small one with the opposite large, so as to make continuous inotion at different speeds in machinery thereby driven, substantially as described.
7. A pair of rolls, each confined between a pair of toothed rims or wheels of diverse diameter, and but one pair of these rolls and one pair of concentric wheels being attached to the driving-axle, the other to be moved by its fellow with alternate speed and slowness, according tothe diameter of the toothed wheel in action, substantially as described.
8. Dies with curved exterior faces, the sectional part so far of a cylinder, either smooth or guttered to lit the metal to be passed between them, and resting at their base upon ares or sections of a smaller concentric cylinder, forming part of the same block or roll for rolling and Shaping metal, substantially as described.
9. Dies of curved exterior face, smooth and fiat on the transverse line or guttered longitudinally, around which metal is passed and shaped by rolling between toothed wheels embraced by suitable housings to produce a series of connected truncated pyramids, substantially as described.
l0. Dies of curved exterior so placed on opposing rolls or blocks as to fall into the interspaces or intervals between the opposite pair of4 molds and press smoothly and firmly between their sides and upon their faces against the interposed metal, curve against curve, circular die against circular base covered by the metal interposed, substantially as described.
