This invention relatesto improvements in ring spacers for matrix setting and type line casting machines in which the spacers, like the matrices, are suspended on a wire and guided in a circular path, andin which the lines set are conveyed by a slide toithe cast-- ing point into a vertically adjustable carriage and after casting are conveyedby the said carriage upwards to the distributing. point.

10 The invention is applicable both to single and to double ring spacers, and willbe described in the followingin connection with double spacers, which are more advantageous for long matrix bars, having two single' spacers of circular shape arranged one above the other.

The non-rotatable parts of such doublering spacers are connected together inawel known manner by means of a bridge, at one side of which are situated the rotatable wedge rings. The bridge is provided at the top with an arm, the upper end of which has a hook by means of which the spacers, like the matrices,

are suspended on aguide wire. The ring spacers are provided in the usual'nianner in their axis-with square openings by means of which they rest during-the justifying opera-' tion on square spindles, by turning which the justifying of the line is effected The use of such ring spacers, which as is well known on sure good pistifying, has only been possible in machines of the kind above referred to i since it has been shown according to German Patent No. 485,370, that the square spindles 5 provided for the turning of the wedge rings may be arranged in such an adjustable manner that after the casting, they can be withdrawn from the ring spacers in order thatit should be possible then toconvey the spacers having with the matrices in the carriage, up wards to the distributing point. In the machines built in accordance with this principle, the ring spacers during their circulation do not move with their axial square openings or recesses on corresponding rods, but their circulation is brought about as already mentioned in the same way as that of the matrices, by guiding them by means ofextension arms provided on their non-rotatable parts, and of hooks arranged thereon, on a guide wire to the collecting or are carried by a slide into the carriage'to the casting point. In this position they are to ustify the lines, and to that end they are suitablyturned by square spindles passing through their axial openings.

The arrangements on machines provided 7 with such a circuit are such that the, square 7 spindles are brought in front'of the casting point and that during the transfer of the line set from the setting (collecting) point to the casting point, all thering spacers of this line arrive with their axial square ope'nings on the square spindles.

After casting, the square spindles are turned back again, to their original positions andare withdrawn from the ring spacers, so that the latter can be conveyed "by the car riage upwards to the distributing point in order to complete their circuit.

In: the ring spacers used hitherto, the wedge rings, owing to their irregular Weight distr bution, have a tendency as soon as the square spindles are withdrawn from the.

openings to turn in such a manner that the,

thickest parts thereof hang downwards; the rings being assisted in thistendency by the vibrations of .themachine. The square openings of the wedge rings assume there fore oblique positions different from one another, so that smooth pushing of the ring spacers over the square spindles impossible. Jamming and ,bendingoccur which always results in trouble inworking, for on that account the lines set frequently cannot be pushed over to the casting point.

The object of the present invention is to, eliminate this drawback of thering spacers hitherto used and to ensure by a special ar .rangement Ol'lztl'lfi ring-spacers that the wedge vrings brought back to their: initial" position after casting, shall be held iminovably also; during the distributingand setting opera.-

tion, in this initial position which is'the same for all, inorder that all theesquareopeiiings" should be always in the position required to receive the square spindles.

This object is attained by securing toeach rota-table wedge ring a spring blade which in the initial position engages over the nonrotatable part. (bridge) of the ring spacer in such amanner that the said bridge is firmly clamped between the wedge ring and the spring. The pressure of the springs is calculated in such a in-anner as to prevent the wedge rings from moving out of theirinitial position under the action of their irregular distribution of weight and of any vibration of the machine.

A construction according to this invention is illustrated by way of example in the accompanying drawings showing a double ring spacer.

The double spacer comprises a non-rotatable or stationary part 1 which, as is well known, is made similar to the matrix bar and suspended with its hook-shaped upper end on a guide wire, and which has in the usual manner two annular portlons 1' definlng c1r-' cular openings in which the wedge rlngs 2 turn with their hubs 3. In the center of the wedge rings 2 are provided the axial square openings 4:, the dimensionsof which correspond to those of the square spindles. In

order to preventthe wedge rings 2 from Wedge rings. These springs: 6 could of course also be made inone piece with the disc-shaped collars 5 since these discs are also secured. to the wedge rings. In order to se-. cure the wedge rings in their initial position in a particularly reliable manner, a still stronger hold can be given to the springs 6 in the said position by providing the non-rotatable part 1 of the spacer with corresponding grooves 7 with which the springs 6 engage in the initial position of the wedge rings. v

After castingth-e line, the squarespindles automatically turn back to their initial positi on and bring thereby all the wedge rings 20f aset line also to their initial position At the thickest can be now withdrawn from the ring spacers,

tion required for 'a'smooth transfer of the ringspacers to the square spindles.
