MEANS FOR TRANSFERBING THE MATRICES FROM THE FIRST ELEVATOR TO THE SECOND ELEVATOR OF A MATRIX-COMPOSING AND LINE-CASTING MACHINE.

Application filed March 15, 1927, Serial No. 175,450, and in Germany August 24, 1926.

convey them to the distributor, whilst leav ing behind the justifying spacebands.

As the matrices, when the first elevator is elevated, are slack as the result of the slackening of the spacebands, and the line therefore is loose, it may happen that thick matrices with ears located on one side, hang slantwise in the first elevator, and in such a case the toothed combinations of those matrices are too low to engage the above named lifter bar when the matrices are moved from the first elevator toward said bar, and these matrices consequently will fall off.

The object of the present invention is to provide means by which the aforesaid diflicultyis overcome. For this purpose, there is provided at the point at which the matrices are transferred from the first elevator to the lifter bar, a spring-controlled stop hereinafter termeda resistant or yielding resistant, which is adapted to bear against the foot or preferably against one of the lower lugs of the foremost of the matrices in course of transference to the lifter bar and thereby bring it to an upright condition and compel all the following matrices of the line to assume correspondingly upright positions. WVhen the line is moved on to the lifter bar, the resistant assumes a position which allows the matrices to be passed freely thereover.

The drawings illustrate by way of example three constructional forms of the invention and in these drawings Figure 1 is a diagrammatic front elevation of the intermediate transfer channel with the lifter bar ready to receive a line of matrices from the first elevator then operatively registering therewith;

Figure 2 is a view similar to Figure 1 with the line shown as transferred to the lifter bar;

Like reference numerals are used to indi cate like parts in all of the constructions shown.

The lineof matrices 1, is assembled from the magazine, and is subsequently transferred to the first elevator all as already known in existing machines. After the line is cast, the first 'elevator2, of which only a small fragment is shown in the drawings, moves upwardly with the said'line, which,

immediately thereafter, is moved along the intermediate transfer channel 3 into which enters the lifter bar 4 of the second elevator.

When the first elevator 2 with the matrix line 1 reaches the position in which it is shown in Figure 1, that is to say, in which it registers with the channel 3 and lifter bar l, the matrix line is moved rightward to? wards said bar 4 by a line shifter pusher similar to that identified by the numeral 5 inFigures '5 and 6, It may happen that the line contains thick matrices such as-those shown in Figure 4 whose upper ears 6, by which they are suspended in the first elevator 2, are located at one side of the matrix whilst the tooth-ed combinations 7 are located upon the opposite side. As the line is slack through the slackening of the spacebands, during the ascent ofthe first elevator 2, the thick matrices will be suspended at a slant as is that shown atthe left of Figure 4, so that when the line is afterwards moved rightward, the combinations 7 are too low to engage with the teeth of the lifter bar 4.

elevator 2 to the lifter bar 1;. The resistant 8 is attached to the upper arm of a lever 10 which is adapted to swing about a pivot 11 fast to the channel In the position shown in Figure 1 the resistant 8 rests against an abutment 12, and projects into the first elevator 2 and, as more particularly shown in Figure 4, brings into erect position any matrices which may be slantingly suspended in said elevator. If, when the resistant 8 is in this position, the line of matrices 1 is pushed on to the lifter bar 1, all the matrices are brought to erect position so as to enable them to properly engage with the lifter bar 4:. The resistant 8 normally is held against the abutment 12 by a tension spring "13 which, in the manner shown in Figures 2 and 3, is connected to it and to the channel casting 3. During the transference 9f the matrix line 1 to the lifter bar 4, the resistant 8 is moved against the action of the spring 13 by the advancing matrix line, the lever 9' as shown in Figure 2, being then rocked clockwise about the pivot 11. The nose of a spring detent 14: thereupon engages with a'recess 15 in the lever 10 and yieldingly holds the latter locked, in such manner that the resistant 8 is prevented from contacting with the feet of the matrices of the advancingline. The resistart 8 remains in this position until the whole matrix line has been transferred to the lifter bar 1 and, after the latter has been raised in the usual manner, the first elevator 2 again descends and when doing so, contacts; with the lower arm of the lever 10 and causes the latter, together with the resistant 8 to turn anti-clockwise and return into the normal position in which said parts are shown in Figure 1.

The abutment 12 is preferably so located that when the first elevator 2 is in its uppermost position, it forms an extension of the guide 'rail and serves to support the matrices during their transfer to the lifter barA- In the constructionaltorin represented in Figures 5 to 7:, the spring-controlled resistant and its lever are formed as single entity identified by the numeral 16 which is adapted to swing about the pivot 11. A spiral spring 1'7 (Figure 7) acting as a triotion brake, encircles the pivot 11 and resiliently holds the resistant 16 in any post tion-to which it may be moved, The spring 17 is enclosed within a cap or cover 17" which is rigidly connected tothe ivot stud 11 as by a pin or the like, and carries an arm 18 which serves to restore the resistant 16 into its operative position. For this pur pose a pawl 0r so-called pusher 19 is 31V- oted to the usual line shifter link 20 attac led to the line shifter'lever The said pusher is 'yieldingly held in the position shown in the drawing by a spring'22. When the line shifter 5 is moved'to the left, the pusher 19 willengage, with the arm 18 and return it to the normal position in which it is shown in Figure 5.

Zhen the first elevator. 2 moves upwards, it will press against the arm 18 and thereby move it and the resistant 16 clockwise against the action of the spring 22, in order to leave t Pa age e r or he ame ding m line 1. As soon, however, as the first elevator. has passed the arm '18 and nears its uppermost position, the spring 22 comes into action and overcomes the brake action'of the spring 17 on the resistant 16, and causes said'resistant to return to its normal position, as in, Figure 5, inwhich it will bear against the foremost matrix; of the line and bring into upright position any of the mat rices which may be inclined in said line,

Finally, Figure 8 illustrates a constructional form in which'the resistant is of. the character of; a roller 23. In this construction the ascending first elevator 2, when it travels past the roller 23, presses the resistant a little way back, that is to say, rightward, and subsequently theresistant isrestored into operative position by the action of a spring which, although not shown in the drawing, may be similar to that shown in Figures 1 to 3. i

It is obvious that the constructional details of the foregoing arrangements may be varied withoutdeparting from the invention, ifor example, in place of the spring detent 1%, a different type of detent may be employed for locking the resistant. The lever 10 and likewise the springdetent 1e are preferably so constructed that when in mutual engagement the resistant 8 will be held slightly away from the advancing line of matrices, so that the latter will not drag over it.

Having described my invention, I declare thatwhat I claim and desire to secure by Letters Patent is 1. The combination with means for trans ferrinr; the matrices from the first elevato of a matrix composing and line casting inachine to the distributor lifter bar, of a resistant located in the path of the foremost of the matrices to be transferred, said resistant by contact with said matrix serving to eiiectthe erection of any matrices of the line which may hang slantwiseprior to their transfer to the lifter bar.
