Description

and useful Improvements in or Relating to' Machines, do hereliine Setting and Casting` owing is an exact by declare that. the fo specification of the saine.

In matrix setting and type line casting machines, for the purpose of producin mixed copy. the matrices are caught; at di ferent levels. During the casting, matrices are then standing with their footor bottom-edge on bars which, after the casting is conipitcd, are withdrawn in order to bring the, inatriceslwth their bottom edge into one plane.

'l`he devices hitherto known have the disadvantage that, owing to the movable bars,

the

it is impossible to avoid a certain inaccuracy in the adjustiiicut of the matrices. lty has already been attempted to obviate th'at. disadvantage by the arrangement of a rotatable i spindle provided with a groove` or by adjusting the matrices for the distributing process without using any mobility in the. said slide, by causing the matrices to pass after leaving the casting carriage and before. they are transferred to the conveyer head, on an oblique surface which brings all the matrices, whatever be the height aty which thev were previously caught, into one plane.|

'lhe construction according to this inven] y tiou luis the advantage over foi-nier con structions, of e'cononiizing the space required for the curved guide behind the east-l ing carriage, and on the other hand of ob,l viating the ditiiculty of the accurate supporting of the movable parts by arranging in a movable manner only a small portion of the bar holding the matrices in their up' ier position. t

he accompanying drawing shows two constructions aceordin to this invention. namely Figure l is a ront elevation of the collector carriage. Fig. 2 is a cross section taken of the line 2-2 of Fig. 1, before the holding liar is retracted.` Fig. Il shows the. saine section after the retraction of the said holding bnr. Fig.'4is a front. elevation of the collector carriage the holding bar being formed as a rotatable spindle. side elevation to Fig. 4 and Fi 6 is also a side elevation after the spinde has been turned. Fig. 7 shows the rotatable spindle alone in a greater scale and Fig. 8 is a side view of Fig. 7 with a portion broken away.

Fig. 5 is a The casting carriage a which carries the matrices to the casting point, and from the casting point. to the distributing point., is generally constructed in the well .known manner and contains a bar b for holding the matrices in the upper level and ledges .v and y for sustaining the upper eais of the matrices standing in ttie lower level. 'ltie bar b is provided in the forni of a fixed projection'of the casting carriage and only nt the point. where it is connected to thc oo nveyer head carrying the nuitriccs to the distributei, there is provided a short movable har c. In the construction shown .1n the drawing, this bar is witlulrawn, during thc rising of the casting carriage, as the bolt l strikes a projection c secured to the traine` and is thus shifted downward against the ressure of the spring f and strikes with its not a ainsta bevel or cani portion q of a movable bar. Owing to the descent of the bolt d, the bar c is thus withdrawn, but.. when the bolt returns to its raised position` a spring h again advances the movable bar.

lt will be clear that tlu` short niovalile liar can lic supported in a very rcliabli"'nianucr. l",\cn when. owing to inaccurate supporting, there is :i faulty adjustment of the matrices, this can tali'c place only on a couiparativcly lshort portion of tht` liuc. 'l`hc liar i which has4 n V-sliapcd section and is arranged on thc machine t'raine above tlu` casting carj riagc aud when the casting carriage o rises upward. cnggagcs with tht` V-lilti` notches of thc nuitrices. can lic provided on the portion corresponding to the movable bar iortion r. with a beveled portion r. as the withdrawal of thi` har portion c takes place during the rising ot' the casting carriage.

ln the construction `shown in Figs. -l-S, thi` movable bar portion is replaced by a `spindle In provided with a groove 1i. The bottoni late'rul surface of the said groove i forms a continuation of the bar I) in the casting carriage u, and the up ier lateral surface of the groove n is of liel'ical shape. 'hen the casting carriage rises into its upper position, the spindle 1uJ is rotated in the. mown manner by the engagementl of the, le` ver o with the screw y) by means of the toothed rack 1]. Owing to tlie helical upper edge of the groove n of the spindle, the matr'iees standing on its bottom lateral surface. are then drawn into the bottom position. The other matrices are positively guided into their bottom iosition during the pushing out of the matrix line from the casting carriage n., as the upper edges of the liottoni matrix lugs slide along the upper lateral surface of the groove 1I.. lPhe bar lif which engages with the V-shaped notches of the matrices, can also lie made partly oblique or curved, in accordance with the shape of the grooves in tlio spindle I).

y MH. the adhesion increased by the coinpres-tv leve s, and only when they arrive at that por- The process during the distribution isl as follows: During the rising of the casting carriage into the position in which the matrices are to be transferred to the conveyer head, the striking of the bolt d against the stop c, or of the lever o against the sci-ew p, causes the movable bar portion c to he withdrawn, or the spindle m to be r0- tated. The matrices standing on the bar portion c, or on the bottom lateral surface of the groove n, fall therefrom by gravity into th'e bottom position. In the construetion shown in Fics. 4-8, they nre, moreover, as already stated), partly pulled down, and the whole line is then transferred in the known manner to the couveyer head. The matrices which are within the casting carriage en the left hand side of the movable bar ortion c or m are then still at different tion of the easitinv carriage in which the movable bar is missing, or has been withi drawn, they all fall into their bottom osii tion. In the construction shown in Pigs.

sion iol' matrices, taking place during thei y teeth transfer. is overcome direct by the helical thread of the spindle. lu the construction lshown in l"i"s. 14%, the depression is brought about already by the above nieiitioiieil bevel of the bar 1", but in order to protect the at the V-shaped notches of the matrices, the bur 1f could be. widened at the beveled portion to such an extent thaty it acts t per edges of the u on the surface of the matrices or on the uppper lugs, by means of aI eam projection am thus tcpresses the mat?E l`l(`(l.`i. i

llaving now particularly described and@v i, ascertained the nature of my said inventionil t und in what manner thc saine is to be performed, I dechire that what l claim is: l. ln a nuitrix setting and line t.asting` t machine in combination a casting curriagei transporting the line to the casting and to the distributing position and containing means to keep the matrices at ditlerent levels upper level, consisting of a ledge having two parts, theone being fixed an( the other the means for holding the matrices in the `3 i tion of the said ledge.

2. In a matrix set-ting and line casting machine in combination a casting carriage transporting the line to the casting anfl to the distributing position and containing means to keep the matrices at different levels, the means for holding the matrices in the upper level consisting of a ledge having two parts, the one being fixed and the other movable, and a bar arranged on the machine above the casting carriage and having a bevper surface being made of y ing upon the iippei' edges of the bottoiu maeled face above t-he movable portion of the said ledge, said beveled portion pressing the matrices during their movement above the movable part, into the bottom position. i

3. In a matrix setting and line casting machine in combination a casting carriage trans orting the line to the casting and to the ist-ributin'g osition and containing means to keep t e matrices at ditierent. levels, the means for holding the matrices in the upper level being formed partly by a ledge fixed on the casting carriage, und partly by -a rotatable spindle provided with a groove. l

4. In a matrix setting and line casting inacliine in combiniition a casting carriage trans erting the line to the casting and. to the istributing position and continuing means to keep the. matrices at ditl`ereiit levels, the means for holding the matrices in the upper level. consistin of two iarts, the one being fixed and tn@ 0 hea* consisting of'a spindle provided with a roove, the up.
