PROCESS 0F MANUFACTURING LATTICE-GIRDEBS.
To all 'whom it may concentr- ABe it known' thatl we, WILHELM DIcKnL and FRITZ. EBENER, subjects of the King of Prussia, residing at Vohwinkel, nearElbeI- 5 feld, in the Kingdom of Prussia andGer- `man Empire, have'invented new and useful Improvements in Processes .of Manufactui` ing Lattice-Girders, of which the following is a specification." I
a process of producing lattice girders from -slitted sheetmetal, metal plates, or the like, in the usual mannerby expandin the slitted material so as to displacethe o ngitudinal truss members connected toeach other by connecting members.
Our process differs from those now in use in that the cuts lor slits, for producing thev longitudinal trussmembers and themembers so as to extend symmetrlcally from themiddle member, in parallel lines, but in opposite directions, so that the displacement 'of both the outer longitudinal members rela-v tivatg the middle member can only beeffecte'dl in op osite directions, and the conneet-ing mem ers between-these outer lon in opposite-directions, so as to be 1nclined oppositely to each other. The middle longitudinal member on this account' is brought intov another plane than the outer longitudinal members. l
Lattice girders producedl according to our l improved method surpass all other lattice girders as regards economy of material and solidity. Moreover, the mlddle longitudinal 1 member cannot be pressedback again into its old position even under heavy loads.
We will now describe our invention with reference to" the accompanying drawing showin our new methodvof producing one form o lattice gider, and in which-:f-
Figure 1 shows an ironplate rovided with double-an le slits or cuts. ig. 2 is Fig. 1. Fig. 3 is a vplan view thereof. Fig. 4 is a cross section on the line A-vA of Fig.

Specification of Letters Patent. 4Application ll'ed July 11, 1911. Serial No. 837,911.
Our lnv'entlon relates to improvements inl connecting and stiiening thesame are made Patentednee. 17, 1912.
The material, .such las sheet metal, metal plates or the like in which double-angle slits or cuts such as shown in Fig. 1, have been made is expanded as shown in Figs-f formed runnin parallel to each other and situated in -di erent planes. These longitudinal members a are connected by members b formed by the cuts or slits.` The connecting members b between `two adjacent longitudinal members extend. in opposite dif rection tothe connecting members between the next two adjacent longitudinal members,
thus imparting to all. the longitudinal members a very great capacity to resist pressure,
so that deformation of the lattice workis practically impossible.
The material employed for oducing these lattice girders'can of courselbe of any desired shape and sectionor thickness, and lattice girders made according to `our invention can be divided into any number of short pieces, without thereby lessening the said :capacity of resistance of the longitudinal members, and their connecting-members.
We claim as our invention Process of manufacturing lattice girders from sheet metal,vmetal plates or the like, consisting in rst making double angle slits extending in parallel straight lines in opposite directions, so as to produce continuous lon 'tudinal truss members and bracing mem ers connecting said truss-members and then displacing by a single ex; wnding operation the alternate longltudinal truss members, so as to force them into substantiallyparallel planes, while, at the sametime, causing said bracing members to assume oppositely inclined ositions.
Intestimony whereo we, WILHELM DIOKEL and Fitrrz EBENER, have signed our -names to this specification 1n the'presence of 'two subscribing witnesses.
