To all llt/ wm it may Concern.'

Be it known that I, TTo STRUNK, residing at. Frien'iersheim, Germany, a subject of lthe llmperor of Germany, have invented a certain new and useful Improvement in ("onveyers, of which the following is a specitication.

This invention relates to that class of conveying mechanisms which are more particularly intended for the conveyance of coils of wire. and which consist of stationary bars and movable bars which latter are adapted to oseillate vertically as well as in the direction in which the material is to be conveyed, and the object of the invention is to so construct such conveying mechanisms that the direction of'tra vel of the material to be conveyed can be changed at one or more points through an angle of 90.

y In the d awing is shown diagraminatically as a' constructional example of the subject matter of lthe invention, av wire conve ver,- which consists of a sect-ion comprising a hot bed and two other sections which abut on aich other and are arranged at right angles to one another, and of which one section sei-ves to convey the coils of wire to the hot bed. and 'the other section distribute-s the coilsl of wire atright angles to the direction iii which the hot. bed conveys the said coils and over the entire breadth thereof. y ln the said drawing,r Figure 1 is a plan view ot' the wire conveyer from which cervtain parts are supposed to be removed, Fig.

2 shows in side elevation a portion of they -wire conveyer. Fig. 3 is a section-on the line 3 3 of Fig. l lookingl from the right. Fig. l is a plan view 'of a portion of the wire conveyer with certain parts in another position. Fig. 5 shows oi. a larger scale a side elevation ot' a poi-tion of the wire convey-er, and Fig. l is a section on the line 6*(3 of Fig. 5 looking from the left with certain parts 'in another position.

A, and A denote the last three preliminary rollers and A the finishing roller of a wire rolling mill. In the vicinity of the finishiirg roller A ai'e four reel standards,

mounted in such a manner that the axes of rotation Aof the four corresponding reels B1, l?. l, Il* are situated in the vertical plane determined by the direc-tion of eXitof the wire from the finishing roller, and are equidistant from each other. The reel standards pins to a. common coupling rod G.

' B are constructed in the form of brackets (see Fig. and are each provided, in addition to the bevel gearing'b for rotating the axially iminovably mounted reel spindles b, with hydraulic mechanism bl bs for moving the reelhooks b" in and out. The construction of the reel hooks f and also of their controlling mechanism are of the well known kind and do not therefore require any further deseription here.

Beneath the reels B1 to `B4 is situated the commencement of a conveying section which serves for the reception of the coils of wire released b v the reel hooks, and for their conveyance on to the hot 'bed M N. This conveying section has al stationary grate formed of bars I) and a movable conveying grate consisting of bars E of equal length.

The bars D are supported their lower parts b v equidistant teeth d2 of combs D1 (see Fig. (S), which are. mounted by means of carrier bars d on stationary supportsvD, arrangedin pairs. ,The movable bars E arranged between the Vstationary bars D, are supported in like manner by teeth e2 of combs 1*". These combs E1 are rigidly connectcd by means of two cross bars e3 to two lateral longitudinal bearers E4, which are movable, in the-direction in which the material is to be conveyed upon rollers F. Below the bars D are mounted bearing supports F, in the bearing f* of each of which a crank shaft 1" rotates. Each crank shaft I1" has .two similar and similarly pitched end cranksf?, about the crank pins of which the rollers.. F rotate. The height of the crank shaft )il is so arranged that, when the outer cranksj/r2 are horizontal, the' upper edges of the bars -E are on the same level with the upper 'edges of the bars D. All the crank shat'tsl1`1 carry at their centers a crank pitched in the same direction as the cranks f2 but at an angle of 90 relatively thereto. The cranks f5 are connected by their crank The crank farthest from the rolling,r mill is connected by a Aconnecting rod A(irl to the shorten crank arm h1 a shaft H provided a connecting rod .l to a rock level' .l1l The free end ot' the rock lever .l is connected by a connecting rod J2 to a transverse girder c5, which connects the ends of the two longitudinal bearers ll1 remote from the rolling mill.

The length of the conveying section I) E is such that it is capable of receiving a 1m11-` coils of wire C. rlhe arrangement is also so constructed that, when the rock lever J1 is in the left hand eXtreme position shown in Fig. 2, the bars E are at the samel height as the. stationary bars I) and lie flush and parallel therewith. lVhen on the other hand the rock lever J1 assumes its right hand extreme position, (indicated by dot and dash lines in Fig. 2) the bars E, which in this position are again at the same height as the bars D, lwill have. been moved relatively to these latter in the direction in which the material is to be conveyedand a distance equal to the distance apart of two adjacent reel axes (see Fig. l). The radins ot' the cranks f1 is less than the halt' of the distance apart ot' two adjacent reel axes, so that the movement ot' the bars E in a vertical direction is less than it is-in the direction in which the material is conveyed. The position which the bars E assume when the rock lever .l1 is in the left hand extreme p0- sition will hereinafter be termed the posit-ion ot' rest.

At the end of the conveying section l) E there abuts at right angles thereto a second conveying section. the function ot' which is to distribute the coils ot' wire over the entire breadth ot the hot bed M N and will therefore hereafter he termed the distributer. 'l`he distributer is driven b v a shaft K, which extendsin the same direction as that in which the material is conveyed b v the distributer. and is so positively connected by bevel wheel gearing with a number of crank shafts /ri carried in bearings K1 and each carrying a crank arm la, that all the crank arms are always parallel with each other. To each ol the crank armsl ZF, (which are all ot' equal length) of each two adjacent crank shafts Zr is 'pivotally connected a carrier K so that the parts K lf2 7; Will have parallel motion. 0n each ot' the carriers K is freely mounted at'ter the manner otl teeth ot` combs a group of conveyer bars k1. All the bars 71:1 lie parallel-with the bars D and ll and therefore at right angles to the direction in which the distributer conveys the material, and all the bars 7&1 remain during the rotation of the crank shaft-s Zr", in one andthe same horizontal plane and, when they are in their central position, are at the Same height as the plane of the stationary bars D. p

The driving shatt KG is so positivelyconnected by spur wheel gearing 7c? lr" to the shaft H, that the carrier K next the conveytiple ol t'our ing section D E and projecting into the path thereof when the n'lovable barsare in their `position of rest, automatically moves out of the path thereof in the direction in which the distributer conveys the material when the said bars are rocked toward the I'ight. When the bars E are in their position of rest, those of the bars [1:1 which in this position are situated in front of the right hand end (See Fig. 1) of the conveying section D E lie exactly inline with and Jorm an ex? tension of the bars. E.A

Next to the distributer yK [c1 at right angles to the direction in which it conveysv the material, and on the Side remote from the carriers K, is situated the hot bed.,4 This latter has a stationary grate formed of bars M and a movable conveyer grate consisting ot bars N of equal length. The mounting of the two grates and the driving mechanism ot the movable conveyer grate N which i's completely independent of the driving mechanism` of the conveyer section I) 1*) and the distribnter K k1, is as isclearly shown in Figs. 1 and 2, constructed in the same manner as in the case of the conveyer section l) E n l and need not therefore be urther. described.'

The bars M and N are mounted near the distributer K k1. The free' ends m1 of the stationary bars M extend to near the carrier K. The same is true of the movable bars N, when they are in their lett hand extreme position (see Fig. l) tween the bars M and N are exactly equal to the distances between the bars l) and E. The bars M and N, lying in front of the right hand end of the conveyer section D E, are so located with relation to the bars l) and ll that the bars E, when they are rocked toward the right, can pass nnimpeded between the free ends 'of the bars M and N. During the rocking movement imparted to them by the cranks k2, the bars 7.21 can also pass nnimpeded between the t'ree ends of the bars M and N.

The action of the whole apparatus is as follows :--1Vhen the front end of a freshly drawn wire emerges, after passing through the preliminary rollers A, A1 and AF, from the'finishing roller A it is led to the first reel B1 and wound thereon in the well known manner into a coil (1. When the reel B1 llas been wound the wire is cut ott' and carried onto the second reel B2. 1n this way each succeeding reel is gradually wound. As soon as the coil of wire on the first reel B1 has been con'ipletelywound, the hydraulic controlling mechanism r of this reel is set in motion, whereby the hooks 7), which support the coil of wire, are drawn back so that the coil of wire falls on to the part of the conveyer section D E lying beneath the reel B1 and the movable bars E ot which are inthe position of rest (see Fig. 1). The reel B1 is then immediately The distances be-V got ready for the reception of a. fresh coil. 'lhe same thing takes place in succession in the case of the succeeding reels. After the last reel B4 has been wound the Wire from the roller A3 is again led to the reel B1, which has in the meantime again become free, and the 'above described operation is repeated. As soon as the last reel B* has let thel coil of wire, wound upon it, drop on to the conveyer section D E, the driving motor H is set in motionA and rotates the shaft H in the direction of the arrow m (Fig. 2) by means of the spur gear h5, It", h3. During the first half revolution of the shaft H the rock lever J1, as can be followed in detail in Fig. .2, is brought into its right hand extreme position, so that 'the movable bars E are moved, in thedirection in which the material is to be conveyed, into the pos`i. tion shown in Fig. 4, and are simultaneously raised by the rollers F, on the cranks f2 so that the. coils of wire C are carried along with them. Since the movementJ of the bars E in a vertical direction, is less than it is in the direction in which the material is conveyed, all points of the bars E describe elliptical curves. The advantage of this in conipa-rison with already known arrangements, in which all points of the movable conveyer bars describe circular lines, is that owing to the reduced lift the amount vof work required of the driving mechanism is rendered smaller. On the second half revolution of the shaft H, the bars E are rocked under the stationary bars D back into their original position. The coils of wire C remain at this time lying upon the stationary bars D, so that after a complete revolution of the shaft H has taken place they will have been moved on toward the right a distance equal to the distance apart of two reel axes. After four revolutions of the shaft H the driving motor H6 is again stopped. The four 'coils of wire C, which originally lay beneath the reels B1 to B4, are now conveyed toward the right a distance equal to the distance apart of four reel axes, so that that portion of the conveyer section which liesV beneath the reels, is againv free to receive fresh coils. sWhen the four reels B1 to B* have been wound for the secondtime, and the newly wound coils of wire let fall upon the conveyer section D E, there will now be upon this latter 2)(-128 coils situated at equal distances from each other. The driving motor is now again set in motion and only stopped when after four revolutions of the shaft H the eight coils of wire have been conveyed four steps farther onward. 'lheI above described operation is repeated in the same manner until the whole conveyor section D E is covered with a multiple of four coils.l If now the motor H6 be again set in motion all the coils on the conveyer section D E will again be moved on one step toward the right during the first revolution of the shaft lH. During this time the coil lnext the distributer K k1 will be deposited by the bars E upon the ends m1 of the bars M forming the stationaryconveyer grate of the distributer and on the ends of the bars N (which are at rest) of the' hot bed and which are parallel with the barsvM. This can take placeunimpeded because'the carrier K of the -distributer, Which -is neXtto the conveyer section Dl E, automatically moves out of the way of the'bars E when the bars E are rocked outward as already stated above.V During the second revolution of the sha-ft H the coils of'wire on the conveyerl section D E will be again moved one step toward the right', so that a.A secondA coil will be transferred to the commencement lof the distributer. At the same time the coil first transferred to the distributer will be moved farther along thereon by the movable bars al thereof, which during this time have. been first raised by the cranks k2 andsimultane ously moved in the.`direction in which the distributor conveys the material, and then returned to their original position beneath soA the free ends of the bars M and N; l This l is then completely covered with coils up to the portion lying beneath the reels B to-fv y B4, and the first four coils are situated on the distributer as is indicated by dot` and dash lines inFigs. 1 and 2.

completely covered with coils. After this, whilethe distributer and the vconveyer section D E are at rest and a fresh coil is being` 'Y wound upon the reel B1, the driving'motor for the movable conveyer bars N of the hot bed is set in motion and is again stopped after the crank shaft of the hot bed driving mechanism corresponding to the shaft ll has made one complete revolution. During this movement all the coils of wire on' the distributer are lifte/dby the free ends of the bars N. conveyed toward the right and deposited upon the hotbed, so that the dis-V tributer again becomes at libertv to receive a fresh series of coils of wire. The driving mechanism of the hot bed N remains atrest until the distributer is again entirely covered with coils of wire.

vlt is then againl set in motion and conveys the series of coils of wire already on the` hot bed one. step 'far. ther toward the right. 'l`he seriesjoflcoils of wire on the 'distributer-.will rbe ';;i 1'nul'.

is again capable of reeeivinga fresh series of coils of wire. The cycle is repeated until" .I 13o Y the hotbed is completelycovered. `\Vhen 1100i The-above described operations,arefre2 y peated until the distributer, which is capa-'V ll ble of holding a multipleof four 'c'oil`s,"i`s'` i they have reached the end ot lt-he hot bed the coils of.wire are cooled and removed by hand to be bundled and shipped.

ln the above described arrangement, the driving shaft K of the distributer is pei'- manently in positive connection through the gear wheels la7 and la," with the shaft H, s0 that when the bars E are moved the bars k1 of the distributor are also moved With them even when the distributer is not covered.
