PROCESS FOR FORMING RIBED LATI-I.
Specication of Letters Patent.
Patented Oct. 1, 1912.
Application led June 24, 1911. Serial No. 835,1205.
To all whom it may concern:
B it known that I, THOMAS H. KANE, a citizen of the United States, and a resident -ofYoungstowml in the county of yMahoning and State of'Ohio, have invented a new and useful Process for Forming Ribbed Lath, of which ythe following is a specification.
This invention relates to ribbed expanded metal or ribbed-lath,` and it comprises a simple, effective and economical method of producing such material. The machines which may be employed to carry out this process are such as are shown in my previous Patents Numbers 949,483, dated February 15, 1910, and 968,361, dated August 23, 1910, but any other means may be employed to carry this process int/o effect.
1`he finished material isof the same general class as is shown in the Kahn Patent l, No. 987,374,'dated March 21, 1911'. Blank sheets are first slitted and grooved, whether the grooving` orslitting comes first is im- .lnateriaL The ribs are then drawn apart Care must to expand the slitted portions. be taken to prevent the ribs from flattening out during the expansion', for Which purpose the ribs adjacent theportion being expanded are engaged by jawspor grippers. The slitting ofthe Sheets may be on any desired plan Or system. The number of ribs in veach sheet may be any number desired. -In the accompanynugr ,drawing which 1s similar to Sheet 3 of my Patent No. 949,483
' above cited, Figure 1 is a cross section of a portion of a machine for expanding the ribbed and slitted material. Fig. 2 is a the material expanded.
The machine has a stationary jaw 1 with a l ;roove tol receive one outer rib 'of the ribbed and slottedmaterial, which'rib lits overl a stationary flange `or plate 2. The Y plate or table 3 is carried by the head 4 and serves tosupport the sheet ymet-al. A movable head 5 carries a lange or plate 6 and jaw 7 to engage the outer rib of the sheet metal, and the supporting plate or table 9. Stationary bars ll'carry the slidable blocks 12, to which blocks are secured means to prevent the intermediate ribs of the sheet'metal from opening. In the pres-v .the subject-matter of this application for patent. y
Havingr now explained my process, what I claim as Thy-invention and desie to sceure by Letters Patent is The process of formilner ribbed expanded metal which consists in laterally separating the ribs of previously ribbed and ,slitted sheet metal while at the same time preventinf.;r the expansion of the ribs adjacent the slitted portion.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
