INVENTOR @ED STATES( PATENTr @EHCEJ4- FLOYD B. CARTER, OF PLYMOUTH, OHAIO, AssIGNOR To THE J. i). FATF OOMFANY,'OF

' PLYMOUTH, OHIO, AVlOORPORATION OF OHIO.

To all 'whom 't may concern Be it known that I, FLOYD B. CARTER, a citizen of the United States, and a resident of Plymouth, in the county of lRichland be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification. f

My invention relates to ware forming machines and it particularly relates to clay cutting machines. c

My invention is particularly applicable to ware, formed by processes wherein the molded clay is linearly ejected from a forming die. The molded clay is then manipu lated and cut up into parts as desired.

The invention particularly has to do with the cutting of the clay along a definite line without mutilation and withdrawing the cutter without injury to the ware, as well as with the manipulation of the clay preparatoryto the cutting process.

In the constructions embodying my invention, the ware, such as tiles, bricks, and other clay products, preparatory to baking are cut by means ofa stretched fine wire or similar cutter, while the formed clay is being conveyed through the cutting machine.

The invention may be contained in many constructions all of which come within the purview of my claims hereinafter appended. To show the practicability ofconstructions embodying my invention, I havel selected one of such constructions as an example and shall describe it hereinafter. The construction selected is illustrated in the' Vaccompanying drawings. .y

Figure 1 of the drawing, illustrates a side view of a machine embodying my invention,

part ofthe frame work being removed in order to show more clearly the construction and operation of the machine. Fig. 2 is a section of the cuttingreel used for supporting the cutters. Fig. 3 illustrates. in

section, an indentation reel used in the manufacture, particularly, of bricks. Fig. 4 illustrates a section through the indentation arm. Fig. 5 illustrates a means whereby Specification of Letters Patent.

the cutting arms or the denting arms may be removed from their supporting pins. Fig. 6 illustrates a side view of a part of the mechanism, showing a buer for yieldingly holding the cutters. Fig. 7 is a transverse sectional view of part of the mechanism shown in Fig. 6.

Referring to the figures, of the supporting frame. 2 are guide tracks for guiding the linked members 3 having the rollers 4. movable over the rtracks 2. The linked members 3 are provided with supporting boards or conveyer plates 5. Y The plates 5 may be varied according to the shape of the moldedfclay, as, when bricks are formed the plates may present fla-tupper surfaces,lor vif tiles are ejected from the molding die, the surface `of the conveyer plates 5 may be cylindrical. The link parts are each provided with endl frames 6. The adjoining end frames 6 are kept in spaced relation. They are provided with cross pieces 7 located on the upper ends of the end frames 6 and forma spacing element between the end frames. The cross pieces abut and then form Va solid continuous frame from near one end of the machine .toV the other. The outer edges of the end 1 is a portion frames are maintained in a vertical position as they are moved along a greater part of tracks.y The upper ends of the frames are rounded so as to, receive and guide therollers l0 mounted on the indentation arms 11 by means of the pins 12 Vwhich are keyed to the arms by means of the screws 18. rThe arms 11 are mounted onthe indentationreel or disk 14;, and are pivotally connected to the plate 14 by means Ofpns 15 keyed to the plate 14 by means of the screw bolts 16. The arms. 1l extend through slots 17, which are large enough to permit a `certain amount of free movement of the arms 11 with respect to the plate 14. The indentation armismade T-shaped and the outeredge is provided `with a ridge 18 having, ysnuous sides 19 propelled position, 2

the same as the length ot the brick sothat as the molded form passes beneath the reel, the upper surfaceI is pressed inwardlyby the edges 18 as the molded 'ormpasses along: Vhen bricks are to be formed, theV` alternate adjoining edges oic the plates 5 are provided'` with upturned portions which press into the molded ormS while it is received -from the die. The upturned portions am-'located centrally with respect to the spaces, between the falternate end trames'fso' that `tl'ieindentationsfforined by the'arms lliare lo,`4 catedopposite the indentations formed by the raised portions 20.

The Vslots' or notches'17 in which thearms 11 are located are made of a width suiicient to allow :for any change of relationbetween the* horizontally moving links 3 and end frames 6` and the rotary movement of the reel14; The'arms'll, as they are rotated, drop against one l end' of: their associated notches 17 as they pass the vertical center line through the axis of the reel. In this they ar-e carried down and enter inV betweenthe-frames 6 and the reel 14 is then propelled `bycontact ofthe'edges or" theranies` Gwith thei rollers 10. The reel 31'h`aving abifurcated'end or cutterfframe 4 clay it iw I 41,- by

It is lthen passe'dover' and through 'a channeled pin 34 ofonefi'ircationland tot and through asimi'- lar ,channeledl pin i located son `the opposite sidefof the frame 32 and 1toathrea`ded rod 36"'and 4drawn tightly'by means "of a winged nut "37 located on the rod on'theoutside 'ot' the'franie32;V The wire`= 30 'is osuitable' inenes's Iso that Jwhenfit is 'pressed' against the 'ill cutllit and sever it into portions.

-The arm 31 is'mounted inthe wheel 40 and@ is f pivotally connected therewith by meansof a pivot pin -41 which is keyed to the wheeli'40bymeansf"of a screw bolt 42.

Thearms extend through slots or notches 43 and have tree 'movements about the pin 41 but within theflimitations of the slots 43. The armslare provided with steel catch pins 44e: which penetrate-recesses 45. `The steel pins are springfpressed by means ofthe` `springs46 which are co-mpresse'dfby means otfthe` tap bolt 47. Each Aarm'31 isfheld yieldingly in position with respect to the pinmeans' ofthe spring'pressed` steel 6 andthe links 3;v The arms 31,'-at. this 4, catch pin 44,* which venterstherecess or channel 45'ormed in the'pivot pin41'.` The As illustrated in the' drawing,v

pvotpin `41 is provided with a rounded or tapered nose, while the pin 44 is provided witha shoulder to"v prevent the` spring46 from pushing the pini 44 out of the counterbored. recess. Frequently while machines of the type shown in the drawings are running,

the Wires break and ordinarily it is necessary to stop the machine in order 'to replace the'broken wire; lhen the wire 30 breaks all that is necessary is to pull the cutter arm oil while the machine continues its operation and put another cutter' arm in its place. This saves loss of a great kdeal ottime in the operation of the machine. rlhe inner end ot thearm 31 isbi'tuicated and* a roller 50 is mounted between the furcations.

Thek reel 40 kis mounted on"the shaft 53 which hasbearings in thestandards 39. Al

cam51 is connected tothe supporting shaft by means of a-bolt 54.`

As' the'links 3,'tcgether-witl`i the molded clay, are carried along, the rollers 48 se cured 'tothe pins 34 and 35, enter between the end 'frames 6 and are carried 'downward and Avertically 'guided by the edges of the encl-;t`iaiiies As the rollers move downl verticallyvwith respect to theclay the wire `cuts the clay. rlfhe arms`31fwhen'k the rollers are moving vertically downward with respect to the horizontally moving' clay, propel the wheel and bringthe arms in succession downward and Iinto cuttingrclae" tion 'withltlie moldedcl'ay.' The wires ot the adjoining arms are'spaced apart so that they will cut along theindentations formedby the ridges 18 on the arms' 11 and bythe upturned portions 2010i1 the plates 5. PinsV 49 located nearthe following side oth'e arms 31, make contact with the leading side of the end frames '6 lasthe cutters 30 are withdrawn from/the plate vand so as to' ad'- vance thecutter with respect to theclay as it'rises from the bottom'edge andpasses the upper edge thereof. The cam'fl, however, is so positioned on the shaft 53, such that the rollers 50 press i against the cam 51 rand tilt lthe-lower ends of the 'arms 3lfor`wa'rd so`f`-thatfitwill'i follow the" endfsurtac'e of each preceding' article' as the links 3 pass?I theincli'ned portion of the track'2. The'` arms which at 'thispoint'arerisinglupward l while' the movement ofthe endit'rames 6 which are at this point moving substantially horizontally with a slight declination. l The pins"49*also'foperate 'to' produce' the clearance-it1 thecain 51 becomes displaced or does not perform' this clearing action correctly.

The` slotsl ornotchesf43 are longenough to* allow the lrequired change in' relativemovement betweentherotated arms and the links` 3./ When the' rollers 48.first'pass between the end frames thewheel 40,'together witlr the arms, arepropelled by the end frames time,l press against the advanced ends of the slots 43. As the frames are carried along during the process of cutting ofthe clay, they lag with respect to they movement of the wheel so that when the cutting portion, performed by each arm, is complete, the arm is located in an intermediate position with respect to the ends of the slots 43. When the cutter 48 is to be withdrawn from the clay andadvanced so that it will not engagek with the clay and to prevent mutilation of the clay, the rollers 50 on the arms 31 move against the cam 5l which lifts the outer end of the arm so as to clear the following piece of ware but not so as to strike the advance piece of ware which at this point is passing down the declined portion of the track. When the cutter is clear ofthe clay, the cam 5l operates on the rollers 50 to raise the arms 3l against the leading ends ofthe slots or notches 43. against the advanced or leading ends of the slots or notches 43 bythe cam 5l until the arms pass the vertical line through the axis of rotation whereupon they'will be held upon the leading ends of the slots or notches by gravity, and until they have completed the cutting operation of the clay each time they are brought in contact therewith for that purpose. c

rlhe cam 5l may be adjusted onthe supporting shaft 53 and the bolts located in the collar 52-to which itis connected. Withn in the collar 52 is provided a brake 57 having preferably a leather face or strap 58 which is pressed against the hub 59 of the wheel 40 by means of the bolt 60 located in the collar 52. Any other suitable material may be substituted for the leather face or strap 58. This operates to retardthe movement of the wheel 40 which is actuated by the pressure of the end frames 6 against the rollers 48 on the ends of the arms 3l. This prevents the 'wheel 40, together with the arms 3l, from getting out of step with the end frames 6 and prevents any jarring while the cutters are in the clay and prevents any 4engagement between the upper ends of the side frames and the rollers 48. i

The wheel 40 runs with a varying velocity and the brake is to control the varying velocities of the wheel and keep the rollers i8 in contact with the end frames 6.

In order to prevent the eect of jarring while cutters are passing downward through the clay, I have provided'a means for keeping the rollers 48 in contact with the following end frame as the rollers pass down between adjoining end frames and to prevent any arring or chattering of the roller with respect to the end frame. By this means, the roller is pressed constantly against the leading edge of the following end frame, and a straight unmutilated cut is produced instead of a wavy or mutilated cut. The pins 34 and 35 are extended The arms are heldY 62 preferably curved'upward so as to pro-- duce a substantially uniform resistance to the pins 60 as'they strike along the arms 62. The levers 6l are pivoted in brackets 63 which may be secured `to vthe frame l by means of a screw bolt 64, .at any suitable point alongthe frame in order to secure the most eiicient operation of the buffer lever 6l when used in connection with the rotating arms 3l. The other end of the lever 61 is provided with a weight 65 which is cushioned by means of the rubber ring 66 located on a pin 67 secured on the bracket 63 when'the weight drops downward as the lever 62 liberates the pin 60 located on the arm 3l.

The buffer lever 6l engages the pins 60 of the arms 3l in succession so that as the arms are guided downward between the end frames 6 and the links 8 are propelling the wheel 40, the rollers 48 are pressed against the leading sides of the end frames-6 preventing any effect of jarring to which the machine may be subject and also preventing mutilation of the cut.

The wheel 40, together with the hub 59 is rotatably mounted on the shaft 53 and is held between the collar 52 and the ring 56 which is keyed to the shaft 53.V The shaft 53 has bearings in the standards 68. Y

TheY construction selected and described may begreatly varied' in the arrangement and constructionof its parts and in the substitution of the elements having equivalent functions and such modifications may still contain the invention;

What I claim as new and desire to secure by Letters Patent, is as follows: l.' The combination of a clay conveyer having end frames, means for propelling the conveyer, a wheel, a plurality of radiating cutting arms having cutters and guide rollers and pivotally mounted on the wheel, limiting ystops located on the wheel and at the sides of the cutting yarms to limit the movements of the arms relative to the wheel,
