MACHINE FUR MAKING METALLIC LATHING.
SPECIFICATION forming part of Letters Patent No. 385,663, dated July El, 1888.
Application filed February 1'7 1888. Serial No. 164.330.
T0 aZZ whom it may concern:
Be it known that I, ANTON EKSTROM, a citizen of the United States, residing at Detroit, county of IVayne, State of Michigan, haveinvented a certain new and useful Improvemcnt in Metallic-Lath Machinery; and I de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention consists of the combinations of devices and appliances hereinafter specified, and more particularly pointed out in the claims.
In the drawings, Figure 1 represents a cross sectional view of a part of an opening-outmachine illustrating my invention. Fig. 2 is a plan view of a slitted and corrugated sheet which has been partially opened out by the opening-out machine, and showing the locality where my improvement is employed.
This invention is designed as an improvement upon what is termed the openingout machine in themanufacture of metalliclatlr ing-such as is shown and described in Letters Patent to Israel Kinney, No. 312,864, dated February 24, 1885-the said machine,with the exception of my improvement, being illustrated and described in an application for Letters Patent by Jefferies R. Branden, filed of even date herewith, Serial No. 264,343. In thesaid Branden opening-out machine the metal is fed forward by a forked arm which engages the metallic strip that has j ust been folded by the folding-dies and moves it forward one space, the design being to leave the next adjacent strip in exact position to be folded by the next descent of the folding-dies. In practice, however, it has been found difficult to properly locate the said strip by the said forked feeding arm, and it is the purpose of my invention to produce mechanism for exactly liningthe new strip to be folded by the folding-dies.
In carrying out my invention, A represents the lower platform and B the upper platform; (i and G, the lower and upper folding-dies, respectively.
All the foregoing mechanism and all the gen- (No mcdeLl the feeding mechanism has fed the sheet forward one space it may or may not be in exact position to receive the next action of the folding-dies; but as the platen descends the fingers 6 will pass into the opening between the last slit that was folded and the new slit to be folded, and will adjust the sheet to its exact particular position for the action of the folding-dies. In this way any slight irregularity in the feeding mechanism or any slight distortion of the sheet is compensated by these liners, which not only adjust the sheet to its proper position, but hold it in that position during the action of the dies. These liners may be made stationary; but I prefer to provide each liner with a springcushion, E, so that as the dies separate, the fingers may be projected well beneath the platen, so as not only to be in position to enter and adjust the sheet prior to the dies com ing together, but to serve also to prevent the sheet from lifting as the dies separate, which it might do in some cases by reason of the metal clinging to the dies.
Each liner is provided with aledge,e,which projects out laterally from the base of the finger e. It extends across the strip that is to be folded, and holds it against displacement as the dies are coming together. The metal is thus prevented from creeping out at one side or the othera tendency which is always present when thin sheet metal is being thus acted upon.
Having thus described my invention, whatI claim is 1. In an opening-out machine for opening out and finishing metallic lathing, 820., the combination, with the folding-dies, of liningfingers c, said fingers connected with a traveling platen and adapted upon its descent to enter between the last-folded strip and the strip next to be foldcd,and adj ustand hold the sheet in proper position for the folding-dies,substantially as and for the purposes described.
2. In an opening-out machine for opening out and finishing metallic lathing, 850., the combination, with the folding dies, of liningfingers 6, connected with the traveling platen, and in connection with said liners springs for projecting the liner beneath the platen and serving as cushions against which the liners may react as the dies come together, substantially as described.
3. In an opening-out machine for opening out metallic lathing, the c0rnbination,with the folding-dies, of a finger adapted to grasp and fix inexact particular position the metal for [5 the dies, said fingers provided with a project ing ledge adapted to extend across the strip to be folded, thereby holding the same against displacement as the dies come together, substantially as described.
In testimony whereof I sign this specification in the presence of two witnesses.
ANTON EKSTROM.
