steps in the process being reducedto' .three or four.
I have illustrated my novel method of manufacturing car-sills in the accompanying drawings, like reference characters in all the figures referring to the same parts.

operation, which consists in turning over flanges along the longitudinal edges of the blank. .Fig. 3 is an edge view of the sheet after the second step in the operation, which involves the pressing of a uniform central longitudinal rib out of the plane of the sheet.
Fig; 4: is an enlarged cross-section of the sheet after the second step. Fig. 5 is an edge view of the sheet after the third step in the process, which involves the deepening of the central rib at its end portions. Fig. 6 an enlarged cross-section of the sheet after the above-mentioned third step in the proce'ss. Fig. 7 is a face view of t is sheet after the third step. Fig. 8 is an enlarged perspective view of tire sheet shown in Figs. 5, 6, and 7; and Figs. 9 and 10 are face views of the sills made from the sheet, the two sills being separated by severing the outer Referring first .to Fig. 1, th e rectangular metal-sheet blank 12 is bent over along the longitudinal parallel lines '13 and 1'4 to form the two marginal parallel flanges 15 and 16. I
The plate is then operated upon to provide the central longitudinal uniform rib 17,-
which may be embossed on or pressed out of the plane of the sheet by stamping or byrolling. T be next step in the operation is the (lee ening of the end portions of rib 1.7 so as to 'orm the parts 18 and 19. This step may Specification-of Letters Patent. Application filed October 30,1905.

be performed either by means of cam-or ecrentric rollsor by means of dies. It should be noted that the pdrtions 1S and 19 taper at 18 and 19 for a portion of their length toward the center of the sheet, as 'will be clearly evident by an inspection of Figs/5 and 8. This last step in the process draws in the metal at the end portions of the sheet,
thus reducing their width, but leaving the center part its original width, so that the sills when severed will be bellied in shape. To separate the two sills, the irregular rib 17 .18
10 is cut on line 20 20, which is parallel to the plane of the sheetfthereby removing the outer portion ofthe rib. A pair of bellied sills of the shape shown in Figs. 9 and 10 is thus produced, each having integral flanges along its opposite longitudinal edges.
Although I have illustrated and described the rib 17 18 1.9 as being pressed from the sheet on the same side that the flanges 15 and 16 are turned over, it will be evident that the flanges and rib maybe formed on opposite sides of the sheet, so that when the sills are A 4' cut apart each will be of Z' shape. Instead of first embossing, stamping, or rollin a unii form rib 17 from the sheet and then so en-- ing the same at the end portions one o the shape including the parts 17, 18, and 19 may be pressed or rolled without heuse of p'reliminary rib 17, thereby eliminating one ste in the operation as described above. It wi 1 be apparent at uniform or unbellied-sills may be produced by this method; but in that cas the center longitudinal rib would be'of i nvarying depth. Other minor variations o1 this method of making car-sills will sug gest themselves to those skilled in the art;
but my invention is'not limited to the details shown and described, and .for that reason is not restricted thereto except to the extent that such details are made the subject matter of specific claims.
1. The method ofmanufacturing car-sills, which consists in pressing a longitudinal rib out of'the plane of a metal sheet-on oneside thereof, and longitudinally cutting said rib whereby two; sills are formed, substantially as describedn 2. The method of manufacturing metallic car-sills which consists in pressing a longitudinal rib out of the plane of ametal sheet on one sidethereof and longitudinally cutting said rib to remove a portion thereof thereby I gral llanges'along its longitudinal edges, subforming two sills, substantially as describe 3. The method of manufacturing'inetallic c ar-si-lls, which consists in turning over flanges e o'ng the longitudinal edges of a metal sheet, pressing a longitudinal integral rib out of the plane of one side of said sheet, and cutting off the outer portion of said rib thereby forming two sills each with an integral flange, substantially as described.
4. The method of manufacturing metallic ear-sills, which consists in pressing out of the planeof a metal sheet on one side thereof a longitudinal rib deeper at its ends than at its central portion, and longitudinally cutting said rib thereby forming two bellied sills each with an integral flange, substantiallyas described.
The method of manufacturing metallic car-sil ls, which consists in pressing out of the plane of a rectangular metal sheet on one side thereof a longitudinal rib deeper at its ends than at its central portion, and longrtudinally cutting said rib to remove the outer portion thereof thereby forming two bellied ,sills each with an integral flange, substan tially as described.
6. The method of manufacturing metallic car-sills, which consists in turning over flanges along the longitudinal edges ofa metal sheet,
pressing out of the plane of said sheet on one side thereof a longitudinal integral rib deeper at its ends than at its central portion, and cutting off the outer portion of said rib, thereby forming two bellied sills each with intestantially as described. 7
' 7. The method of manufacturing metallic car-sills, which consists in pressing alongitudinal integral rib out of the plane of a metal sheet on one side thereof, deepening the end portions of said rib, and longitudinally cut ting said rib, thereby forming two sills, substantially as described.
8. The method of manufacturing metallic car-sills, which consists in turning over flanges along the longitudinal Y edges of a metallic sheet, pressing a longitudinal integral rib out of the plane of saidsheet on one side thereof, deepening the end portions of said rib, and cutting off the outer portion of said rib, there by forming two bellied sills each with integral flanges along its longitudinal edges, substantially as described;
9. The method of manufacturing metallic car-sil ls, which consists in turning over flanges along the longitudinal edges of a rectangular metal sheet, pressing a eentral'longitudinal integral rib of uniform depth out of the plane of said sheet on one side thereof, deepening and tapering the end portions of said rib, and
severing." the outer portion of said ribon a hne parallel to saidsheet thereby forming two bellied sl-lls, each with integral flanges along its longitudinal edges, substantially as described.
