To all AL11/om 'it may concern.'

Be it known that l, lYiLLL-ui J. Mc.- Citicltex', a citizen of the United States, residing at laullina, in the county of O`Brien and neiv and useful Improvements in Tile-Making Machines, of which the following is a f therebeneath formers or plunger heads being alternately' specification.

This" invention relates' to improvements in tile making` machines.. and particularly to means for making tile pipes and the like 'from plastic material of any desired kind, as for instance cement.

Heretofoi'e in constructing tile making machinesl dilliculty has been experienced in providing inechanir-:m that is adapted to run continuously and yet form tiling intermittently. Usually the. tile making machines' heretofore known present a. single mold or a plurality of molds into which a plunger is adapted to be forced for forming tile, and then again rtanoved and therinechanism brought to a standstill or to an inoperative position while new molds are being placed beneath the plungers and new material is being fed thereto prelmratorvto a second compression of the material for 'forming a tile. l

'ln the that are suggested and to arrange for a continuous operation of the driving mechanism and the intermittent molding er forming of the tilingI by means of a plurality of molds and plungirs brought into operation intermittently or successively, one mold or set of molds` as the case. may be being operated while the other is being held ont of operation or out of contact with the mold.

In `carrying out the features of the present invention a suitable framework is pi'ovided having a plurality of reciprocating and rotating shafts carrying plungers for forming formers that are adapted to lit into suitably arranged molds that are brought in succession.' the respective present device mea-ns are presented brought into engagement With the molds of the respective mold` carrying tables. Connected with both of the reciprocating' shafts is a rocking bai' that is adapted to move longitudinally or reciprocate the respective rccipi'ocating shafts. for .causing one of.- the plunger heads oi' formers to engage themiold on one side of the frame While the former or State of Iowa. have invented certain adapted to overcome the objections their respective former or plunger head to be disengaged'Y from its mold While the other plunger head former is being engaged by its' mold. Connected Withthe rocking arm is a receiving pocket that is. adapted to receive cement or the llike from Which the tiling is intended to be constructed that Will delivei' to the re-` spective molds material subsequent to the descent oi" entrance of the former into the mold so that `positive means are provided for supplying each mold subsequent to the entrance ofthe former therein with material for forming the tiling, each movement of the positively formed. In this Way a mechanism is provided that is adapted to receive cement and to feed the same alternately in proper amounts to each side of the frame of the machine intermittently into the molds, and to then have the cementpin the mold formed into a proper shaped tile immediately after action of the plunger head or ing therethrough. As cach successive mold has formed therein a tile and the former is moved therefrom the mold will be moved from beneath the another mold actuated for taking the place of the previous mold ready for receiving the next quantity of cement preparatory to forming the next succeeding tile. A rotating table is provided on each side of the ma.-` chine that carries any desired number of molds that are brought successively beneath the plungers on each side of the machine so that when one. plunger is forming a tile on one side of the machine the plunger on the other side of the machine is moved and the table is being rotated fdr bringing the next succeeding mold beneath the plunger. This operation continues intermittently and the respective tables are rotated step by step so as to bring their respective molds beneath formers for having tile formed therein. As the mold having a formed tile therein is moved from .beneath the former the same isi'emoved to any desired place for disposal or for .permitting the same to dry as the case mayy be. andan and in this Way upon former a tile Will be` plunger or former andempty mold is placed upon the `table in. placev I thereof. j l L- y: y Iii-carrying. out t-he object oftheimiention and arranging a structure for forming tilin various structures may be providedan'd various changes may be adopted within the spirit ofthe invention.

In order to disclose one embodiment of the invention Ihave shown vin the drawing the preferred structure in which: Figure 1 is a side'elevationof a complete il .'machlne. Fig. 2 is a front elevation. Fig.

Fig. 11 isA an enlarged dev tail ,fragmentary sectional view through a mold, showing one of the plunger heads or Fig. 12 is an edge view of Fig. 9 on a reduced scale.

n 'constructing a machine according to the present invention any desired liind of frame or supports may be provided. In the drawings `theframe comprises bars 1-1 and 2"-2 which are secured together in any de- .sired manner for forming a base. To this base are secured uprights 3 3 and 4-4 which in turn are secured together by cross braces 5 5, 6-6 and 7-7 'on the ends of the frame and cross braces 8-8, 9--9 and 10-10 upon the front and back. This framework arranged with these cross braces forms a rigidl and firm support for the various operating mechanisms hereinafter fully described.

Mounted upon the base are revolving tables 11' and 12 that carry any desired Anumber 'of

molds

13 and 14 respectively. .The molds are arranged in a circle on each of the tables so as to be brought successively beneath the

respective formers

16 and 17. The tables are pivotally mounted upon the vbase formed from beams or bars 1--1 and 2`-2 and are adapted to turn, upon pivotal or journal members 18 and 19.. The jourvnal members 18 and' 19 project to near the top of the molds for assistingthe workmen in placing the molds in position, though it will be obvious thatthe members 18 and 19 maybe' shortened. A bearing extension or` 20isfor'med upon table 11 and a bear- Y extensionorrhub 21' is formed upon .zlel2p'l`hese bearing extensions or hubs i i V d a'pted' to rest upon'thebase ofthe y egfya'nd. j have the respective y ournal members `18 and 19 pass therethrough. lrrojecting from the heads or bearing

members

20 and 21 are pins 22 and 23 that are adapted .to beeequal in number to the numberlof molds on the respective tables and are en# gaged by hooks 24-24 secured to operating rods 25- and 26 respectively. The

respective rods

25 and 26 are formed with beveled ends 27, as clearly` seen in Fig. 7, which are adapted to strike against the respective pins 22 and23 and permit the

rods

25 and 26 to slide alongthe same until the respective hooks 24-24 have snapped over or passed one of the pins 22 and 23. The rods 25 and molds 13 and 14a pair of chutes 28 and 29 l are mounted in the frame with one end so positioned as to discharge material in the molds mounted upon the respective tables 11 and 12. The upper ends of

chutes

28 and 29 are connected with a receptacle or hood 80. The material is dumped into the hood 30 and from thence into the

chutes

28 and 29 respectively as the case may require. The hood 30 is preferably held in position by being secured -to uprights 31 and that are mounted between cross bars 8 and 9. Passing through hood '30 is a journal 33 that has secured

theretosprocket wheels

34 and 35, sprocket Wheel34 being adapted to convey motion to shaft 33. Rigidly 'secured to.v

shaft 33 (Fig. 4) is a pair of

arms

36 and 37. The arms 3G and 37 have passing therethrough'set screws 3S and 39 that. may be.

adjusted as the occasion may require for limiting the movement of the blade or dividing member 40. rlhe blade' or dividing member 40 is loosely mounted upon shaft '33 and is adapted to divide the h ood 30 or to form a movable partition therein. Rigidly secured to blade 40 are a plurality of blades or shelves 41 andi 42`wh1ch, together with blade 40, form pockets for receiving the ma teriahdumped into hood 30. When al given quantity of material has been dumped into hood 30 and caught between blades 40 and 42 the same Wi-llb'e retained in that position until shaft 38 has been rocked and motion n conveyed therefrom through arm 36 and ser screw 38 to blade 40. As blade 40 is thus i rocked the blade or shelf 42 will also be .rocked and moved to the position shown in dotted lines in Fig. 4. This will permitthe material located between' blades 40 and 42 to drop by gravity down chute 29. At-the' same time, thatmaterial r is permitted to isc . tothe position sho successively dro -upon cross bars or y that down chute 29 blade or shelf 41 will'm-ove to such a. position as to catch the next 'quantity of material deposited in hood and will hold the same until shaft 33 has rocked sufficiently tor causing arm 37 and set-screw 39 to move over and force blade 40 thus drop This will dump 40 and 41 into chute 28 and will at the same time permit shelf 42 to catch the next suc ceeding quantity of material deposited in hood 30. By tl 33' material dumped into hood 30 will bc ped into one chute and then theother, Sha 33 is adapted to be rocked in unisonwith the up and-down movement of ormers or plungerheads 16 and 17 so When formcr'l'7 is in its lowermost position, and material is dropped into chute 28 when 'former 16 is in its lowermost position. In order to accomplish this shaft 83 is moved Aby sprocket 34 which through a chain 43. Chain 43 passes over Sprocket 44 and is rotated by shaft 45 which is supported in .jou

members 10`l0.

The bearing members 49 and 50 are arranged I -witha sleeve formed with a square hole me. -idesscaiand wiil passing therethrough and lriphery. Around theeylindrical periphery isv arranged a block :teri'or engaging the sleeve that is formed with a square hole or aperture passing therethrough. Each of the bearing members 49 and 50 1s constructed in this manner so as to permit the free reciprocation of shafts 47 fts being l 'and 48 therethrouvh, these sha square though it will be evident that a round shaft might be used. and the respective members that are designed to rotate the shaft be keyed or splind 'theret o as occasion might require.

Positioned above and below lbearing block 49 are collars 51-51 that are held i in place by suitable set screws so that any jmovement ot Walking beam 46 will be conveyed to shaft 47 for recip Projecting from block 4S) are pms 52 52 :that pass through a slot 5 ing beam 46 so' as to. accommodat 52-5L. The pins-52?@ may be ordinary bolts or screws if desired. iBearing block 50 is provided with collars yheld in )lace by set lock .49 andv parts ot' the structure therefore `need no fure pins .also the surroundino Wnvin full lines in Fig. 4. the material between blades l 1e successive rocking of shaft I" material is only dropped into chute 29 Ain turn receives power rnal bearings mounted to shaft 45 is a rocking talking beam 46 y l-is adapted to extend a short distance beyond A a cylindrical pe- 'having a cylindrical inrocatingthe same.

formers

16 and 17 will be moved upward and downward or reciprocated in unison orin proper relation to the way material is dumped fromhood 30 to the

respective chutes

28 and 29. .l In order to provide means for .supplying y hood 8() with material an elevator 54 is connected to the framework in such a manner that the bucket therefrom will dump matcrial at intervals into hood 30. Elevator 54 is preferably constructed on the bucket and ,i chain type are held in place'by chains 57 and 58. The i chains 57 and 58 are adapted to pass over sprockets 59 and G0 mounted upon a shaft l 6l at the upper end of the frame and `to l pass over suitable sprocket-s mounted in'a i rece tacle 62 which are -mounted upon4 av i shafrtiGS that passes through the receptacle, the receptacle G2 being mounted near thev base of the frame. Shaft 6l is held in posi-Iy tion by a plurality y addition to carryingsprockets 59 and 60 carries a gear wheel G5 near one end thereof.' g Gear wheel 65 is adapted to mesh with-a j gear wheel 66 and is rotated thereby. Gearl I' wheel (5G ismounted upon a shaft (37 whichv has secured thereto a sprocket (S8. Sprocket l (38 receives power't'rom a chain (39 that passes l l l l over sprocket 70 loosely mounted upon shaft 7l. A clutch 72 of any desired description is also mounted to connect sprocket- 70 With shaft 7l so that I power may be communicto sl'irocket 70 i 54. Shaft 71 has secured thereto a pulley 78 that receives from any desired source. ln operation shaft 7l is adapted to be continuously rotated but b v reason of clutch 72 thrown into and out of i may require but the remaining mechanism will continue to operate. Shaft 7l is mounted in 1 oxcs 75 and 76. Secured t fend thereof are beveled that `mesh4 with beveled gears 79 and 80. Beveled gears 79 and 80 are formed with a l l l suitable bearing o shaft 7l at the gea rs 77 and 78 square hole or aperturel therethrough through which the

square shafts

47 and 48 pass, the gears being slidably mounted upon said shafts but rotatable therewith. Projectingl l from cross members 7--7 aro guiding journals or brackets 8l and 82 which assist in y guiding the reciprocating shafts`47 and 48.. and also prevent a downward movement ol` I gears 79 and 80. The brackets 8l and 82 l may be formed asseen in Fig. 8 with a cylin. drical sleeve 88 mounted therein through which the square shaft is adapted to pass. In addition to the guiding journal members or blocks 8l and members orblocks 84` and58-5 are secured to 1n. which

1 71 is rotated

shafts

47 and 48 will be rotated l and by reason of the factthat both of the gears 79 and 80 are positioned above the gears 77 and 78 they will be rotated in re versedirections so that when the

threads

88 and 89 upon the

respective formers

16 and 17 engage the cement or other material of which the 1tile is formed an upward movement of the

shafts

47 and 48 will be given at the same time that the shafts are rotated, the rotation of the shafts'being caused, by power from shaft 71 and the upward movement of the respective shafts for afshort distance being caused'by'the respective spirals or

threads

88 and 89 acting againstthe material in the mold. After the threads of one of the formers have forced the former out of the mold, as lfor instance former 17, the same would stay at a standstill in that position if other means werefI not provided for further raising the same. .In order -to provide this additional movement a screw or threaded sleeve 90 is rigidly secured to. shaft 48 that engages threads 91 formed in a nut or what might be more properly-termed a half nut 92. The threaded sleeve 90 is adapted to engage threads 91 at the same time or slightly previous to the time that threads 89 haveraised the former out of the mold. In order that block or nut 92 may be in proper position for permitting threads or sleeves90 to engage threads 191 the same is moved over-so,` as to be in proper alinement with sleeve 90 by sliding bar 93 (Fig. 3) longitudinally across the top 'of' the frame. Bar 93 isheld in positionbybrackf.-. ets 94 and95 which permit'aslight up and down movement-as well as a reciprocatory movement, springs 96-96 being provided for normally forcing bar 93 to itsv extreme upward osltion.

In ort` er that-bar 93 may be reciprocated an arm 97 is adapted to pass through an aperture 98V formed in Vbar 93 and is .adapted to. engage adjustable guides 99.

Guides 99 are preferably formed with slots therein through which suitable bolts are passed into bar 93 for clamping the guides 1n any desired position. By this construction and arrangement the guides 99 may be adjusted toward the center of aperture 98 or away from that point for permitting arm 97 to engage soonerv` or later the respective guides and veonsei'lue'ntlyv act upon bar4 l 93 sooner or later.

Arm 97 lis rigidly se.

Sprocket 35 is 1 rigidly secured to s'haft33 vin orderto se cure power therefrom.` Shaft 33, as here-l tofore set forth, receives power `:from shaft 45 through sprocket wheel 44, Vchain 43, and

sprocket 34. By this arrangement of ower` conveying means shaft 100 will be simply rocked and will be rocked in a certain re-I deterinined relation to the rocking of s aft 1 l 45 tolwhich is secured the walking beam 46. This lwill re late the action of arm 97 so as to throw t e nut'92-over to a position to be en aged byvsleevet'90 at the proper time that r the opposite end of nut 92 is another nut 103 similar to nut 92 and adapted to enga e a sleeve 104 rigidl secured to shaft 47.

Just before shaft 48 reaches its lowest point walking beam 46 will actuate the mechanism heretofore set forth for movin arm 97 sufficiently to cause nut 92 to a position above sleeve 90.- As

e sleeve 90 is raised. Positioned .on

nut 103 will only engagem sleeve continues to rise by the actionof f spiral threads 89 on the former sleeve 90 will en age nut 92 and will be positively raisedt ereby. As soon as nut 103 has been moved from beneath sleeve 104 shaft 47 toi* gether with sleeve 104 will move down until ormer 16 is in 'the lower part of the mold f ready for compressing material placed in the mold.

In operation they material of lwhichV the 105. This receptacle 62 may be of any desired kind, but preferabl 'of ample size to contain a-pair- -of-Y sproc (et --wheelsearoiind which the chains of the elevator may pass, and also a suitable supply of cement that is ada ted to be' scooped up and elevated by

buc ets

55 and 56. After'the cement has been placed in I,receptacle 62 the machine is started by applying power to pulley 73.

'This will cause shaft 7l to rotate and conseizo

uently cause shafts

47 and 48 to rotate. lutch`72 is then engaged by arm 106 being actuated for pullin cause clutch 72 to rigidly connect sprocket 70 with shaft. 71.. This will convey motion to chain 69 and from .thence to shaft 167 through sprockets 68.; Frdmghaft 67 power "'isconveyed'throughgearfjylieel 66 to gears wheel 65/ and from lthenceitofshaftg 61. Manned on v`emit ...Basket labels.'

59 and 60 around which pass chains' 57 and 58 that carry

buckets

55 and 56. Poweris thusconveyed from pulley 73 to buckets 55 Which will receive cement from receptacle top ofthe frame of the machine and dump the cement into hood where it is caught by blades 40 and42 or 40 and 41 as the ease may be. If the material is caught between blades y and 41 the 'same will be dumped into chute '28 and pass through the same as seen in Fig.

2 dinto one of the molds 13. Previous to the dumping of the material from between blades 40 and 41 into chute 28 former 16 `will be lowered to the position shown in `"'Fig. 2, and also the framework 108 will be lowered. Frame 108 carries a hopper or hood 109 which receives and guides the material from chute 28 into one of the molds 13.l The hopper 109 is adapted to project "above frame 108 and be'ozt such a size as to4 form a substantially flared continuation of each of the molds 13 as the same is moved over thelrespective molds. A plate 110 is bolted or otherwise rigidly secured to hopper 109 preferably near the bottom"y thereof orl across the bottom and is formed with an aperture 111 through which former 16 is .adapted to pass. Plate 110 may be re'- 4.moved and replaced by one having a hole H"of ar different size for forming different sized tiles as Vthe case may require. It will be of course evident that the former 16 must be changed when the tile is to be :changed in size as well as the mold.

Frame "108 is'adapted to move down by gravity to aposition above one of the molds 13 when.A

permitted to do so by the movement walking beam 46, but it will be evident that aspring may be secured to the same for y"positively moving the same down to subist stantially a .horizontal position as seen in Fig..2.,

After the cement or other material. used in .making tile has passed through hopper 106 into mold 13 the. rotation of former 16 will cause the threads 88 to engage the cement and pack the4 same in spiral layers around the former and against the sides of l the mold. As the cement is packed around the former 16 the spiral or threads 88 will press against the same and gradually rise until the spirals or threads have moved en- Y tirely out of the mold. At thisinstant. or ...slightly before-this period the threads on sleeve 104 will engage nut 103 and as the shaft carrying. the plunger will continue to rotate the same will be raisedby the action of threads on sleeve 104 against the threads or nut 103. The raising of shaft/47 by the action of the-spirals or threads"'88 andalso the action of sleeve 104 against nut.f103 will cause walking beam 46 to lower shaft 48 and consequently lowerformer 17v to a 'position similar to the position of 'former 16 as shown-in Figs. 2 and 11. At the'salne time that plunger or former 17 is lowered blades 40 and 42 will be moved over to the dotted posit-ion shown in Fig. 4 and permit cement to be fed through'chute 29 into the mold 14 that contains the plunger or former 17. As former 16 leaves mold 13 walking beam' 46 is raised and consequently raises a recipro-4 eating bar 112 that is connected therewith. The bar 112 passes through a

pair ot rollers

113 and 114 secured to pivotally mounted

arms

115 and 116.

Arms

115 and 116 are pivotally mounted upon frame 108 and are adapted to move

slides

117 and 118. The

slides

117 and 118 are formed preferably with semi-eircular notched outends and are adapted to move inward. upon the pivotal bearings ot'

arms

115 and 116. lVhen slides or

plates

117 and 118 have moved inward they take a. position above the newly formed tile and hold the same in the mold while the lowerpart of the former is being pulled therefr, m. This will prevent any tearing or breaking of the tile. slides 117 and 118 to move inward and take a position above the tile bar 112 is formed with an enlarged portion 119 that is conneeted with the main body portionby a bevel 120. This will spread rollersv 113 and 114, and consequently move

slides

117 and 118. After

rollers

113 and 114 have traveled the full length ot'enlarged portion 119 they will engage a stop 121 that will pivotally` raise fraaie 1.08 and its associated parts upon its pivotal journal bar 122 which is mounted in suitable uprights 123. Rod. 112 together with enlarged portion 110 is adapted to be of such a length as to not cause stop 121 to move frame 108 until the lower end of the former has moved out of the newly formed tile.

Pivotally mounted upon shaft- 122 is a bell crank lever124 that is actuated by a rod 125 connected with walking beam 46 preferably by passing loosely through an aperture therein and having a nut formed on the end of the rod so. that as the walking beam moves downward rod 125 will be stationary and will remain stationary until walking beam 46 has moved above a predetermined point, preferably ahorizontal level. The nutor stop positioned 011 the end of rod 125 is adapted to be engaged immediately after the former has been moved from the mold, and as the walking beam 46 rises farther rod 125 will be moved upward and will act upon bell crank lever 124 for pulling upon rod 26. This will rotate tablb 11 for bringing another mold beneath the former as heretofore set forth. As former 16 is raised and frame 108 is raised for permitting table. 1l to be rotated for bringing a new mold beneath the former, former 17 is lowered and is ladapted to receive material' thatvihas been depositedI from one of the buckets 5.5` V and 56 between' constructed in a similar manner to frame l vbe lowered and vice versa so that tiles will be' formed alternately on each side-of the,
