IMPRQV EMENT IN CQRRUGATING-MACHINES.
Specification forming part of Letters Patent No. 40,897, dated December 14'), [S63 fanteda'ted December 6, 1863.
To all whom it may concern.-
Be it known that I, JOHN G. BAKER, of Washington. city and county, in' the District of Columbia, have invented certain new and Useful Machinery for Gorrugating Sheet Metals; and I do hereby declare that the fol lowing is a full and exact description thereof, reference being had tothe accompanyingdrawings,a nd t0 the characters of reference thereon marked. I
In the drawingssimilar characters reterto .cams which operate the upper diejaws, and
also showing arrangement of dies for making the simplewave-line corrugations. Figs. 4 to 11, inclusive, are details showing the operation in forming'ouc bend at atinie of 'the corrugation, as will hereinafter fully appear.
The' nature of myinvention consists in corrugating sheet metal, &c., between alternating die-jaws, 'or their equivalents, in such a manner as to form but one bend or angle of the corrugation at a time, and also in feeding the sheet to be corrugated by its own weight.
' A is the'frame-work of cast-iron, and made sufiiciently strong to resist the outward lateral pressure resulting from the resistance of the corrugating-sheet. B is the flooring upon which it rests.
1, 2, 3, and 4 are the cast-iron die-jaws, of a suflicient length to embrace the entire width of a sheet of metal. These jaws are cast in cylindrical quadrants, and are provided with heavy radiating arms 1, 2, and 4, the arms of the upper jaws 3, and 4, passing through suitable slots in the faces of the lower jaws, 1 and 2. (See Fig. 3.) These jaws are arranged in pairs-that is, jaws 1 and 4 tit and move closely over or under each other, being turned concentrically from their comoperate against the lower edge of die-ja'w 4. It will be seen that by this arrangement or procesti m of cams thediejaws 1 and 2 are first moved forward simultaneously by the double set of cams 0, then the die'jaw 3 is operated by the smaller cams, D, and then the die-jaw 4 by the smallest cams, E.
I and J (in blue lines, Fig.2) are a series of spring-dogs on one of the axles 0. They are operated by means of the rod'e upon the cams. The heads of dogs I are somewhat lower than those of dogs J, and the lower ends of dogs j J are somewhat lower than thei lower ends of the dogs I.
K are braces which serve to guide the sheets of metal and to afford the requisite resistance to the dogs.
L is the table; M, the gearing, (shown in red lines in Fig. 2;) N, the journalboxes of the axlesc, on which are the main spur-wheels and the cams G D E.
0 are steel shoes, which are attached to the lower edge of dieja'w 4 at the points operatedv upon by the cams E. These shoes areused only when making the wave line corrugation. By means of these shoes 0, I can make either theridged corrugation, as shown in Figs. 2 and 6, or the wave-line corrugatiomas shown in Figs. 3 and 11.
The operation of the dogs (which are hooked out of the way when formingthe wave-corrugatfon)isas follows: The lower edge ofthe sheet of metal isinserted between the diejaws, and rests upon the heads of the upper dogs, J. As the cams revolve, the rod 0 strikes against the lower bent ends of dogs J and moves their heads from under the sheet, thus permitting the sheet to fall until it rests upon dogs I. The jaws now form the corrugation, as will be hereinafter described. When the first corrugation has been formed, the jaws separate and the lower dogs, I, are drawn back so as to mit it (the sheet) to fall down until its first corrugation rests upon thelower dogs, I.
By this device the weight. of the sheet of inetal causes it to fall down,while the dogs catch it, and release it, and catch it again, holding in suitable position for the formation of succeeding corrugations. The heads of these dogs should be made adjustable so as to give greater or less width between the corrugations.
When I wish to form the ridged corrugations, as show-n in Fig. 2, the sheet of metal a: to be corrugated is fed down from the table L between the die-jaws until it rests upon the dogs I. In the mean time power is applied to the driving 'pulley, which revolves the spurgearing M and the cams 1. As the cams revolve, cams 0, having the boldest profile, 0perate before the other cams and strike against the lower edges, d, of the die-jaws 1 and 2, raising them upward and carrying them forward in a curve until they clasp the sheet of metal at 0, the die jaw 1 passing over and beyond the die-jaw 2, thus bending the sheet of metal over the die ofjaw 2, as at 'i, and forming the first angle or bend of the corrugation, as shown in Fig. 4. The series of cams D then operate in like manner upon die;jaw 3, making it bend the sheet in the opposite direction over the now stationary die-jaw 1, and forming the second bend. at, ofthe corrugation, as is shown in Fig. 5. in like manner upon die-jaw 4, causing it to bend the sheet againin an opposite direction up against the now stationary diejaw 3, thus forming the third and last bend, a, ofa ridged corrugation, as is sh own in Fig. 6. The first corrugation now being formed, the highest points of all the cams are brought into the same lines, so that the weight of the die-jaws will make each pairof them simultaneously separate from each other, slip off from the cams, and fall down and re at upon the journals-of of their axles, as at z.
\Vhen I wish to form the plain or wave corrugation, (shown in Figs. 3 and 11,) I attach the steel shoes 0 to the lower edge of the jaw 4, (see Fig. 3,) so that when the cams E'operate against the die jaw they will throw it farther forward, so as to make it pass over and beyond the die ot'jaw 3, as in Fig. 11, instead of coming up against it, as in Fig. 6, when 1 make the ridged corrugation.
Informing the wave corrugation, I first bring the jaws 1 and 2 together. The edge The series of earns '13 now operate of the sheet of metal is then set upon them, as seen by the blue line in Fig. 4. The jaw 3 then closes down upon the sheet, holding it as shown in Fig. 7. The jaw 4 then forces the sheet in the opposite direction and over of the corrugation, as shown in FigLB. As the jaws now separate and fall'down, as above described, the sheet falls with them in such together the jaw 2 will enter the bend of tho first corrugation just made, forcing 'it up against jaw 1, as shown in Fig. 9. Jaw 3 now forms the first bend of the second corrugation, as is shown in Fig. 10. Jaw 4 then forces the sheet in the opposite direction over jaw 3, thus forming the second bend of the second corrugation, as is shown in Fig. 1.1. Thejaws -now separate,and when they come together again jaw 2 will enter the corrugation j ust left by jaw 3. The process is thus continued until the whole sheet is corrugated. When it is wished to change the pitch or shape of the and substituteothers in their'plaees of the deseveral sets of die-jaws of the various shapes desired. v
I In my intention I possess the advantages of being able to corrugate sheet metals with one-half (or less) the power required in any injury to themetal from stretching or straining it, like the machines which form more than one bend at. a time.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. Corrugating sheet metals, &c., between alternating die-jaws, or their equivalents, in such a manner as to form but one bend or angle in the sheet ata'time.
2. The die- jaws 1, 2, 3, and 4, constructed and operating substantially as described.
,3. The dogs I and J ,constructed and operating substantially as described.
4. Feeding the sheet of metal by its own gravity, in combination with the corrugatingj LWS, or their equivalents, substantially as described.
