MACHINE FOR THE MANUFACTURE OF CHAIN MAIL.

Application filed August 26, 1921.

To all whom it may concern.

Be it known that I, EMIL Mt'iLLnn, a citizen of the German Republic, residing at Pforzheim, Germany, have invented certain new and useful Improvements in Machines for the Manufacture of Chain Mail, of which the following is a specification.

This invention relates to a machine for the manufacture of chain mail in which the finished chain mail is alternately held suspended upon two groups of opposite holding organs displaced the one with regard to the other. The known machines of this type work in such a manner that the chain mail hangs with its last row of rings upon the holders of one group and that each newly added ring is gripped by the holders of the opposite group which go up successively. In a machine of a known type the corresponding holders of the first group of holders descend simultaneously when the holders of the opposite group ascend. The working method is similar to the knitting process as the rings are successively caught by the holders of one group to be successively transferred to the holders of the opposite group.

Vith other machines all the holders of one group are lowered simultaneously when the new row of meshes has been formed.

The fact that in the machines of both types the holding organs consist of single frail holders which are driven individually is the reason that these holders are easily damaged wherefrom result irregularities in the formation of the chain mail.

This invention obviates this inconvenience by using combs whose teeth serve as ring holders. The improved construction according to this invention presents the further advantage that the chain mail is not suspended by the last row of rings but by the last but one row of rings. The teeth and the comb are constructed in such a manner that when the teeth get into the plane of the chain mail, that is to say into the plane in which the finished chain mail is suspended, the rings of the last row are placed vertically.

The advantages resulting from this construction are obvious, the vertical position of the rings of the last row of rings enables the secure insertion of the new rings. The rings of the last row of rings are absolutely free from the holders. The chain mail is absolutely at rest until the whole row of Serial No. 495,726.

rings is finished as the combs are stopped during the formation of the rings which is very favorable for the secure insertion of the individual ring meshes.

In order that the invention may he clearly understood, I shall proceed to describe the same with reference to the form of construction shown by wav of example in the accompanying drawings, wherein the improved holder for the chain mail and its working method are illustrated in i figures.

Fig. 1 is an elevation.

Fig. '2 is a plan view.

Figs. 3 and 4 are detail views illustrating the positions of the tools after the formation of a row of ring meshes.

a and b are the comb-shaped holders for the chain mail; 0 and d designate the teeth of the combs which have curved backs on. Said teeth stand apart from one another at a distance which corresponds with the diameter of a ring. The teeth of the two combs are displaced, those of one comb with regard to those of the other comb, for a distance which is equal to half the diameter of a ring.

As shown on Fig. 3 the rings of the last but one row of the finished chain mail hang upon the teeth 01 of the holder 6. Fig. 4 shows the rings f of the last row of rings in vertical position bearing upon the back of the teeth 0 and supported by a shoulder of the comb a.

The formation of the ring meshes and the insertion of the individual ring meshes g for the formation of a fresh row of rings is effected in the well known manner, the pieces of wire 9 having been bent previously to U-shape being inserted by a tool (pincers) 70 into two adjacent ring meshes of the freely accessible last row of rings f to be closed to ring shape by a counter tool 2' (Figs. 2 and 3). After in this manner a complete row of interlocked rings has been inserted the free mesh holder a is made to V the finished chain mail is alternately held suspended by two groups or" opposite holders, comprising in combination elements for guiding the chain mail, two inwardly inclined reciprocating combs the one at the one side and the other at the opposite side of the chain mail, and upwardly directed teeth of said combs standing at distances apart which correspond with the diameter of the rings of the chain mail.

2. In a machine for the manufacture of chain mail of the type described, two in wardly inclined reciprocating combs one at either side of the chain mail, and displaced the one with regard to the other for an amount equal to half the diameter of the rings of the chain mail, upwardly directed spond with the diameter of the rings of the chain mail said teeth designed to en 'age with the rings of the last but one row 01 the finished chain mail the curved backs oi the teeth bringing the rings of the last finished row of chain mail into the vertical position In testimony whereof I alfix my signature in presence of two witnesses.
