METAL-WORKING.
Application filed February-11, 1913.
My invention relates particularly to the manufacture of what, is commonly termed expanded metal.
The object is to provide a simple and inexpensive mechanism for expanding slitted sheets at high rate of speed in a uniform without injuring the stock.
In its preferred form, the invention contemplates mechanism for a ting upon a pro viously slitted sheet of metal which is corrugated longitudinally and opening out certain of the corrugations as the sheet is moved through the machine. 7
Figure 1, is a longitudinal view showing the ends of a series of rolls foracting upon the material according to my invention..
Fig. 2, shows the arrangement of gearing on one side of the machine diagrannnatically. Fig. 3, shows the arrangement of gearing on the other side of the'niachine diagrammatically. Fig. 4, is a View at the receiving end of the machine,' parts being broken away. Fig. 5, is a similar view showing parts of one of the last pairs of rolls for spreading the stock. Fig. this a similar View of a corresponding pair of rolls of slightly different form. Fig. 7, is a. fragment: ry view showing one arrangementiof slitting. lfig. 8, is an end view of a sheet with longitudinal corrugations in the unslitted portions.

Fig. 11, is an end view of a sheet in which the unslit'ted portions are longitudinally corrugated as in Fig. 8, and the slitted portions are opened into mesh work by a longitudinally corru gating action. Fig. 12, is an end View (on a somewhat larger scale) of part of the same shown spread out into a relatively flat sheet. Fig. 13, is a fragmentary view of one form of fabric expanding according to my invention. Fig. 14, is a. diagrammatic plan view indicating the method of expansion according to my invention and showing the relative shape of the cross sec- Specification of Letters Patent.

tion of a sheet at the different progress through the machine. diagrammaticside view tive flattening of a sheet.
The sheet is preferably first slitted as shown in Fig. 7 so that it consists of unslitted strips bv slitted portions such as 2, 2. The slitted portions are expansihle and the slitting is stages of its Fig. 15,1s a showing the relain any suitable arrangement but preferably as shown. laclrslitted section may have two parts such as 3, 3 united midway hetwecn the strips 1, 1, for instance along the strip -l-. The sheet may be corrugated lon gitudinally along the unslitted strips as shown at l, 1 and 4:, *1 Fig. 5: if desired either in preliminary treatment or by rolls such as 5 and 6 in Fig. 1. These rolls engage the strips 1, l and feed the slitted sheet into'the machine.
The slitted portions are subjected to a 1011 gitudinal corrugating action in a n'evious treatment as shown by my Patent #1052588 or in my application #741,376 filed January 11, 1913, or by n'ieans of rolls such as the rolls 7 and 8 so that the end view would. appear as in Figs. 1 or 1]., the arti( :ular secupon whetherornot the unslitted strips are corrugated. The rolls 7 and 8 will feed the stock into the machine even if the rolls such as 5 and 6 are not used.
Rolls 7 and S are made up of shafts such as 9 and 10 supported by suitable housing such as 11 and having a series of disks such as 12, 12 and 13, 13 which interuiesh and a passage correspond ing to the shape o1 the cross section oi? the stock at this point as shown for instance by the zig-zag line 1-1 in l ig. 11. The zig-zag line 15 represents diagramniatically the cross section of a passage between the rolls 1(3. and 17. The zigzag line 18 represents the cross section of the passage between the rolls 19 and 20 and the intermediate zig-zag lines in Fig. ll represent the cross sections of the passages between the other successive rolls. The lines R, K represent the ribs or longitudinal unslitted strips such as 1, l of Fig. 7. The dotted lines such as'Ql and 22 represent the positions of the si .ccssive rolls. The full, line 23 represents the relatively fiat sheet of expanded metal at the point as it passes through between the rolls 2- and 25. The rolls 26 and 27, 28 and 29 serve to iron out or ribs such as 1, 1 connected' and smooth the stock by relieving internal stresses in the metal and distributing the strain uniformly so as to produce perfectly flat product, that is a product without buckles or irregularities. These rolls also serve to feed the product oiit of the machine.
It will be noted that according to the arrangement and relative 'n'oportions of the rolls and their spreading disks, the corruated stock at the beginning of the spreadmg actions is operated on rather abruptly but this does not injure the stock as it is'at. this point very flexible laterally. As the stock is widened out however, it becomes laterally less flexible and for this i'eason the longitudinal unslitted strips or ribs are brought out into their proper relative position more gradually so that the curve which they take is substantially tangential to their final position in the finished sheet. It will also be noted that while the longitudinal strips or ribs lt travel in a substantially horizontal plane through the machine, the intermediate portions, strips or ribs. as the case may be, as indicated at 30 gradually rise as they more outward so as to subject the stock to as little stress as possible. Directing guides such as 31 may be employed between the successive pairs of rolls. shape of the cross section of the successive rolls also depends upon the results which it is desired to produce and it should be understood that many modifications in details of construction and arrangement of parts maybe made without departing *lroin the spirit or scope of my inventioiu The rolls 1!) and 20' oi- Fig. l) are ribbed and grooved respectively to treat a fabric having grooved iinslitted longitudinal strips such as is shown in Figs. .11 and 12. 1f the longitudinal strips are grooved by rolls such as and 6 at the entrance to the machine, the other rolls will be ribbed and grooved as indicated in Fig. b, to allow for the longitudinal corrugations or the longitudinal strips may be lorgitudinally corrugated by means of the rolls sucli'as shown in Fig.6.
All of the lower rolls ol the machine and some of the upper rolls are power driven as indicated by the dotted gear pitch lines in Figs. 2 and 3 and thus exert a tiactive or feeding force on the stock throughout the entire machine.
