Specication of Letters Patent.

Patented Mar. 3o, 1920.

Application filed'september 28, 1915. Serial No.153,063.

To all whom t may concern:

Be it known that I, OLIVER J. MoUssnTTi., a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Brick-Machines, of which the following is a specification.

The invention has relation to the type of machines for making bricks or like building strain incident to the compressing` of the material in the' formation of the brick, sucli strain being neutralized vupon the shaft which operates the compressing elements, said elements being arranged' so as to compress the material between them.

The invention further aims to provide 4 means whereby the mold disposed between the compressingl elements is free to move when said elements are separatech'the parts being so arranged that when the compressing'elements are moved apart the mold is advanced, thereby bringingV the next succeeding mold in position to have the material compressed for forming the brick and the brick previously formed brought into position to be removed from the mold.

A further purpose of the invention is to obviate wear upon the bricks while moving l from the compressing mechanism to .the egector and at the same time relieving the bed from wear and preventing the dragging of the brick thereover.

The invention also contemplates novel ac tuating means for uncovering the bottom of the mold at the proper time to insure deliv-` ery of the brick from the mold, and again covering' the bottom of the mold preliminary to placing -material for forming the next brick in the ,mold

The invention also has for its object the provision of a novel mounting of the table whereby the table may move easily and the mounting will be protected from the accu mulation of foreign matter which would the formed bricks from the ma tend to clog the parts and interfere with the proper operation of the machine.

The invention also aims to loperate the endless carrier and rotary table in unison thereby preventing any dragging motion or unnecessary expenditure of power in the operation of the machine.

The invention furthermore has for its object to devise a machine which in operation will form a plurality of bricks at a single operation, all of such bricks being delivered from the mold with sharp and well defined corners.

Another purposeA of the invention is to so dispose the magazine that the pallets are supported partially by the same, thereby en-v abling the carrier to be operated by a less force andwear than is the case where thev pallets are supported with the entire weight resting upon `the carrier.

The invention also has for its object to devise novel actuating means for the platen which Amay be readily adjusted to insure positive engagement between the platen and the slide closing the bottom of the mold in which the material is compressed, and also to provide positive actuating means for the several working parts and to have such actuating means disposed so as to be readil)Y accessible Jfor replacement or other' puroses.

Vith the foregoing and other objects in view the invention may be said to consistof the novel features, details of construction and combinations of parts which hercinafter will be more particularly set forth. illustrated in the drawings hereto attached and subsequently claimed.

Referring to the drawings,

Thegmain' frame comprises a pedestal 1, abase 2, aftower l'3. and' offstanding or bracket `portions 1', 5 and 6. rlhe pedestal portion 1 of the .frame is provided at its top With'ahorizcntal portion 7 forming a bed upon .which an 'annular member 8 is rotatablyA mounted, such -member constituting the tablewhich is provided at regular intervals with mold cavities or openings in which are fitted molds9. The tower 3 is centered upon the pedestal 1 and secured thereto in any substantial way and is formed at its lower end with an outwardly extending flange 10 which is of circular outline and, is elevated slightly above the bed 7. The rotary table 8 is formed upon its inner wall with a flange 11 which slightly under laps the outer portion of the flange 10. -Antifriction devices are interposed between the portion of the track' and endless car-` inner circular wall of the rotary table 8 and the outer verticaledge of the flange 10. rThese anti-friction devices preferably consist of rollers 12, the same being supported upon the inwardly extending flange 11. A cap ling 13 secured to the flange 10 extends across the space formed between the table v8 and flange 10 and retains the rollers 12- successively into position foi-proper opera tion of the compressing devices upon the brick forming material deposited in such molds. The gear ,wheel 15 makes one complete revolution for each actuation of the rotary table and the cog gearing' between the parts' 8 and 15 is of such relative construction and arrangement as to insure a proper movement of the table at each operation thereof. The mutilated gear wheel 15 is cured to a vertical shaft 1G vwhichis located at one side of the machine and is mounted at or near its ends in suitable bearings; as indicated most clearly in Fig. 1.

Arranged to cooperate with the molds is a plunger 17 and a platen 18, each being mounted to receive al vertical reciprocatory movement and directed in its-movements by any approved form of guide. The plunger 17 is located above the rotary table whereas the platen 18 is disposed in vertical alinement with the plunger beneath the rotary 'table and they receive, a simultaneous move.- .ment in opposite directions whereby they advance or move apart, the material in the mold being compressed during the advance. The platen 18 is mountedvup'on the guide rods 19. The plunger 17 is mounted in guides 2O attached to a side of the tower 3. A main shaft 21 is mounted in suitable bearings forming a part of the main frame and is provided. with eccentrics 22 and 23 with which the usual eccentric straps are ar ranged to coperate. A pitman 24 connects the eccentric 22 with'the plunger 17. Pitmeny 25 connect the eccentrics 23 with the platen 18 or a pin 26 passing through such platen and having its projecting ends connected with the lower ends of the pitmen 25. The eccentrics22 and 23 have an opposite arrangement, that is, when the leccentric 22 is operating to depress the plunger 17 the eccentrics 23 are operating at the same time to move the platen 18 upsite directions. As la result of this arrange-A ment of the eccentrics the fr'ameiiwork of the machine is relieved of all strainincident to the compression of the material during the formation of the brick, such strain being im-- posed directly upon the main shaft 21 and neutralized thereon by the-opposite movement of thel plunger and platen. j

The bricks are dislodgedv from the molds by an ejector comprising a plunger 27 'which is mounted to reciprocate in a guide 28 loy shaft 21.` Coperating with the plunger 27 is a platen 34 which is mounted to receive a Vvertical reciprocatory movement, being directed in its vertical'movementsby means of a suitable guide 35 attached to or forming a part of the main frame. 4Theplaten 34 -is lelevated when receiving the brick from-the mold thereby preventing any jar which would tend to distort or mar or otherwise injure the brick by dropping'a distance after being forced from the mold' bythe plunger. After the platen 34 has received y the brick from the mold it descends so as to place the pallet containing the brick upon the track over which it is moved in its delivery from the machine.

`The platen 34. is carried byr a stem 36 which is mounted in the guide 35. One end of the operating lever enters an opening formed in thel stem-36 and said'lever com-v prises two members 38 and 39, both loosely mounted upon a shaft 40. The members 38 and 39 have a relative adjustment and for this purpose the member 38 is formed with laterally extending spaced ears 41 in which are litted adjusting screws 42. The member 39 has an extension 43 which projects into the space formed between the ears 41 and is adapted to be engaged by the inner ends of the adjusting screws 42. It follows that by backing one of the adjusting screws 42 and advancingthe other adjusting screw the members 38 and 39 of the lever may be relatively adjusted so as to insure moving the platen 34 to a position to obtain the best results whenelevated to the limit of its throw by the means :operating the said lever. The member 39 is provided at one side with a roller 44 to travel upon a cam 45 secured to a shaft 46. By this means the outer end of the lever is elevated thereby depressing the platen 34 and depositing the brick dislodged from the mold upon the track in position to be delivered from the machine. The lever is counterbalanced by means of a weight 47 whichl is adjustable upon a rod 48 attached tothe outer end of the lever. The weight 47 is of such mass' and position with reference to the lever as to over .balance the platen 34 and the weight of the brick thereon. `This arrangement provides for a slight movement of the platen 34 so as to obviate any jar and prevent anyA possible injury to the ibrick. y

A track 49 is arranged at one side of the machine and below the plane of the rotary table and its supporting bed 7. This track may he supported in anysubstantial manner and of any'preferred length and construc tion providing it comprises two rails whichare transversely spaced and so disposed as to receive opposite ends of the pallets 50. V'

An endlessI carrier 51 is arranged in the same vertical plane with the track and 1s adapted to move the pallets along the track into position to `receive the bricks as they are dislodged fromthesmold and to deliver the bricks lfrom the machine as they are formed. The endless carrier 51 comprises companion chains or belts 'which are supported at opposite points by means of.

sprocket wheels v52 and .53.4 The sprocket Wheels 52 and `53 are provided in pairs and are secured to shaft/S54 and 55 whereby the sprocket wheels of each pair rotate in unison. In the operation of the endless carrier the upper run travels from right to left and in order that the upper run of the endless carrier may be operated by means of a pull-- ing force rotary movement is positively applied to the shaft 54. This arrangement keeps the upper run of the endless carrier taut and prevents any buckling thereof which would be the tendency if the shaft 55 were positively rotated yand the upper run of the` endless carrier moved by a pushing force. Certain links of the endless chains comprising the carrier 51 are provided with projections 56which are adapted to engage the rear edge of a pallet 50 and move the same along the .track 49. The projections 56 are 4located upon opposite sides of the chain or belts comprising the carrier and extend upwardly alongopposite sides of the members comprising the track 49 as indicated most clearly in Fig. 7. This arrangement of the projections 56 results in maintaining the endless members of the carrier in line with the members comprising th/c track.

The shaft 54 is provided with a gear wheel gear G2 which is in mesh with a bevel 'gear 130 63 4fastened to one end of a shaft. 64 which, in turn7 is provided at its opposite end with a bevel gear 65 meshing with a bevel gear (56 j attached to the lower end of the vertical shaft 16, said shaft 16 being provided at i ts upper end' with la bevel gear67 which is in mesh with a bevel gear 68 attached to a horij zontal shaft G9 mounted in suitable bearings at the top lof the frame-work. A gear wheel 70 secured to the shaft 69 is in mesh with a -gear wheel 71 fastened to the main shaft 21.

A gear wheel 72 secured to themain shaft 21 is in mesh with an idler 7 3 v. hich in turn is in mesh with a pinion 74 secured to a shaft 7,5 upon -which a"y bevel gear 76 isl'secured and which meshes with a pinion 77 fastened to .a drive shaft 78. A band pulley 79 is secured to the shaft 7 8 and is adapted to receive motion from a suitable. source of powerA bycmeans of a driveA belt 80.` The gear wheel 58, being mutilated, imparts an intermittent movement'to the `gear wheel 57, hence intermittently actuates the endless carrier. The. gearing is so timed as to insure a movement of the endless carrier whereby a pallet is brought into position vposition to be .elevated for receiving'tlie nent brick dislodged from the,mold.

The magazine 81' for receivingthe pallets l50 is located at one end of the track 49 and is inclined to the vertical thereby throwing the pallets 50 at an inclination tothe vertical, so that the greater part 0f the weight of a pile of pallets is sustained by the lowery wallE of the magazine will be readily understood. This arrangement also greatly facilitates vthe )withdrawal of the pallet at the bottom ofthe pik` by the projections 56 of the endless carrier.

As the lowermost pallet of the pile moves forward the weight of the pile in tilting is sustainedV bythe lower or rear wall of the magazine S1 as indicated most clearly in Fig. 8.

Each' of the molds is closed at its bottoni by a slide SQ'which'is retained iii place and directed in its reciprocating movements by suitable guides' disposed upon the under side of the rotary table 8. moved outward to" permit the dischargi` of the bricks and are moved inwa'rd to close the Ibottoms of the molds and held in such inner position during the time that the molds receive a charge. of material, while such material is being compressed to form the brick, and during` the movement of thev brick from the compressing mechanism to -sliaiik 87 of the detent.

The slides S2 are :liessen/i the point of discharge. Each of the slides is provided at its outer edge with a depend- Y .when such slides are moved outward and fully uncover the molds when the latter 'preach a position in line' with the ejector.

After delivery of the brick fi'om the mold,` 'as the table moves forward the slide is closed or moved inward by the projection 83 riding upon the cani 85. To reduce the friction to the smallest amount possible the 'depending projection 83 may consist of` a pin or stud having a roller or sleeve fitted thereon to. bear against the cams 84 and 85. After the table 8has been rotated to bring the molds into proper position with reference to thel compressing and ejecting mechanisms, it is desirable to secure the table and prevent possible movement thereof. For this purpose a detent' is provided, the saine consisting of a head 86 and a shank 87. |The head 86 is toothed to engage the toothed edge 14 of the rotary table. A bracket 88 projecting from a side of the pedestal 1 is formed with a guide S9 which receives the A lug 90 projects upwardly from the outer end of the hori Zontal portion of the bracket 88 and receives an adjusting screw 91. An eXpansiblehelie cal .spring 92 is interposed between the outer end of the shank 87and the inner end of the adjusting screw 91 and normally serves to yhold the detent pressed inward` with its toothed portion in `en g'agement with the toothed portion 14 of the table. A lever 93 fulcrnmed between its ends to' van arm 94 projecting upwardly from the bracket 88 has one end connected to the shank 87 of the deftent. Thev opposite end of the lever 93 is provided with a projection 95 which is lo! cated in the path of a cam 96 secured to the vertical shaft 16. The parts are so proportioned and arranged that when the table is rotated forward by means. of the ear wheel 15 the detent is thrown outwar thereby or comprise any number of mold cavities Thepr'ojcction 95 is preferably in the na- -ture of a roller mounted upon astud'or pin vcarried by the free end of the lever 93 so as to-reduce the friction when riding upon the cain 96 to the smallest amount possible.

Each of the molds 9 may be of any size at one operation. It is to be understood,.

however, that the number may be increased or diminished as required. It is noted that the` upper edges of the partitions 97 are square, this being of advantage in preventing the formation of small pieces which usually dropback upon the face ofthe Y' bricks and are subsequently compressed by lso Alo

the action-*of the ejector, thereby forming obj ectionable spots upon the surface. The plunger head 99 is hollow and V1s adapted to be supplied with a heating medium such as steam, the latter being supplied thereto from a suitable source by means of a hose pipe- 100. The yface of the plunger head 99 comprises a plurality of compressing elements 101 which are adapted to enter the respective mold cavities 98. These compressing elements 101 are separated by spaces 102 which are of a size to snugly receive the partitions 97. The lowerfaces of the compressing elements 1301 are protected by means of wear plates 103 which usually consist of hardened steel. The plunger head 99 is usually cast and the Wear plates 103 are subsequently fitted `to the faces of the conipressing elements. vThe construction is such as to permit any one of the wear plates 103 to be readily replaced when worn or otherwise rendered unfit for effective service. I

The ejector head 104 is constructed in substantially the same manner as the plunger head 99, as shown most clearly in ig. 7.5

Steam or other heating medium is supplied to the head 104 by means of a hose pipe 105`r which leads from a suitable source of supply. Thel parts of the ejector head 104 corresponding to the .compressing elements 101 are longer than the corresponding parts of 4 the plunger head 99 so that they may enter the mold to a greater depth and thereby force the bricks from the mold cavities 98. A detailed description of the 'ejector head 104 is deemed unnecessary ,as the same is of like construction tothe plunger'head 99,

corresponding parts being designated by the i same reference numerals. j ln the operation of the machine the palj lets are placed in a pile in the magazine 81 and the clay or other brick forming material is supplied to the molds in succession necessary vertical i pressure.

ed that the platen 18 is moved upward l against the bottom of the slide 82 before the plunger 17 reaches the limit of its downward movement, such platen 18 being held momentarily in contact with the slide 82 during the completion of the stroke of the plunger 17 in the final compressing of the material to form the bricks. This arrangement of the parts is essential in order to prevent injury to the slide 82 and its guides as also to prevent subjecting the tableto unj Simultaneously with the operation of the compressing -mechanism, the bricks previously formed are dislodged from the mold in register with the .ejector by theoperation of the`latter.

The' bricks after being formed are supported in the molds by means of the slides or bottoms 82, thereby preventin the dragging of thel bricks over the bed As the full mold reaches a position in line with the ejector the -slide or'bottom 82 is drawn outward by the laction of the cam 84 in the manner rhereinbefore stated and when the mold reaches a position inV line with they .ejector the slide 82 has beenfully drawn out so as to uncover the mold. At this time the ejector begins to descend and the platen 34 commences to rise, said platen being elevated in time to -receive the bricks from the mold, thereby preventing any jar or injury to such bricks while in the green state. After the bricks have been received upon the pallet l50-supported by the platen 34, the latter begins to descend, thereby depositing the platen with its load upon the track As the table resumes its forward rotation the endless carrier 51 likewise begins its movement, thereby bringing the next pallet into position above the platen 34 and at the same time removing a pallet from 'the bottom of the pile contained in the magllO pallets 50 and enable the same to'pass freely `thereover.vv A roller bed formed of a plu-.

downwardly therefrom. After the pallets clear the track 49 they are received upon the roller bed 106 and gravitate to the predetermined point'of discharge. It is to be f understood that the bricks may be delivered from the machine in any preferred way so as to be stacked for drying and baking.

To operate the machine by hand for setting or adjusting' the parts to insure a ,consonance of operation, a spur wheel 1.07 is secured to the outer end of the shaft 7 8- and a lever -108 is mounted upon said shaft at* one side of said' wheel.

A double ended dog 109 is pivoted to the-- projecting end of the lever 108 and is adapted to be moved so that one or the other end thereof may be brought into position to engage the teeth of the spur wheel 107 whereby the mechanism may be moved slightly in one direction or the other as found most convenient to admit of properly adjusting the parts to insure accurate registration of the several members.

`It is to be understood that in theformation of a machine of the character and for the purpose herein stated various changes in the form, proportion and-minor details of construction maybe resorted to without departing from lthe nature of the invention as claimed. v

It is proposed to apply to each of thev hollow plunger and `ejector heads means forpcarrying off the water of condensation.

. These-means are illustrated most clearly in Fig. 5 andare substantially the same for, each of the hollow heads and comprise a pipe 110 constituting a header and a plu- 'rality of pipes 111 extending from the pipe i 1'10 to within a short distance of the'bottom of the hollow head so as to receive and carry ofi' all the water 'of condensation when the outlet is open. A hose pipe`1l2 connects with the pipe 110 to 'carry oil the water of condensationto a suitable point of discharge.

' Each of the slide plates 82 is formed with openings in coincident relation with the' mold spaces when such plates vare at the.

mold 9.- The follower is 'supported and di i'ected in its movements by a plurality of guides 115 depending ,from the slide plate 82. .When the follower is at its lowest posivtion the upper faces of the blocks1l4coincide with the plane ofthe upper face of the" slide'plate 82. "When the follower is elevated the blocks 1'14 project upwardly into the lower portions of the mold spaces and compress the material therein. The follower 113 is adapted toibe engaged by the platen when the latter is moved upwardly in the manner hereinbefore stated and such movement occurs simultaneously with the downward movement of the plungerso that the material in the mold is compressed from above and below at the same time.

The follower is moved downward preliminary to the outward movement of the plate 82 so as to withdraw the blocks 114 from the mold. Q The means for depressingzor lowering'the follower comprise'two cams` 116 and a pair of pivoted arms 117. A bracket 118 projects outwardly from the pedestal 41 andk the arms 117 are pivoted thereto.v Each'of the arms 117 is `providedat its free end with `a pair of rollers 119 and 120. These rollers are mounted upon a transversely disposed pin carried by the arm and projecting over opposite edge portions of the plate 118. The rollers 120 are arranged to engage the vcams1'16. The forward en'dsfl of the longitudinal edge portions of the plates 113 are downwardly deflected, as indicated most clearly in Fig. 16" so as to pass beneath the. rollers 119 yand thereby cause such rollers to ride upony the edge portions of the plates 113 and depress Athe same. This occurs when the rollers 120 -ride upon the lower faces of the cams 116. The cams`116 and the arms 117 are disposed upon opposite sides ofthe followers so as to engage with the plates 113 and effect a lowering of the 4followers sofas to `withdraw the blocks 114 from themold spaces. This operation takes place after the final action of the compressing means and preliminary to the action of the'ejector.

It is preferred to operate the table by means of a variable movement which is slow at the beginning then accelerated and finally Y diminishes. This movement' obviates shock and strain on thegearing` and connections. Figs. 18 and `19 show gearing for eiecting this result. In Fig..l8. the shaft 2l is provided withan elliptic gear wheel 71a which meshes with. an elliptic gear wheel 7 0'rl upon the' shaft 69 which is geared tothe vertical shaft 16 by means ofthe bevel gearing 67 and 68. In'the modification shown in Fig. 19 the shaft 619A is' provided with a gear wheell 70b mounted eccentrieally thereon and .in mesh with a a gear wheel 71b mounted in an l eccentric manner upon a shaft to which the gear wheel 7 8 is secured and which gear wheel 7 3. is in turnl 'in mesh with the gear wheel 74 on the shaft 5. It'

will be understood by reason of the coperating gears 70 and 71a and 7 Ob'and' 71 being mounted in the manner` stated, a vafr-i-able movement is imparted to the rotary table lwhich when traveling 'from one Amold to the, other starts slowly, has its movement accelerated and then comes to rest by a gradually diminishing movement, thereby avoidingany shock to the working parts.

As shown most clearly in Fig. 10 the iso \ employed if desired.

toothed portion 14 ,of the rotary table is interrupted at regular intervals by portions 14 which are smooth and made concave, suoli portions projecting beyond the base line of the teeth so as to enga-ge with the smooth portion 15a -of the mutilated gear 15. The toothed portion of the mutilated rear 15 corresponds with the toothed portions 14 of the rotary table comprised between the interrupted portions 14a, this being necessary in order to move the rotary table the required distance at each operation thereof. The smooth portion 15a of the 'mutilated gear 15 rides upon the smooth concave-portions 14 of the rotary table and holds the latter stationary and in proper position during;` the operation of the compressing' and ejecting mechanisms. As vindicated in Fig. 2 there are two compressing mechanisms indicated at A and B. The compressing mechanism indicated at A initially compresses the material plac d in a mold and in the forward rotation of the table such mold is supplied with additional material before reaching; the compressing` mechanism B which imparts the final compression to the material in the formation. of the bricks. The initial compressing mechanism A is substantially the same as that embodied in the compressing mechanism B and which has been described --hereinbefore in detail. It may be stated that it is not desirable or expedient to provide a platen mechanism to cooperate with the compressing` mechanism A although the same may be During` the action of the compressing mechanism indicated at B the follower is elevated-by the action of the platen 18 in the manner hereinbefore stated and in the forward movement of the t-able the follower is depressed by the means 117 and 116 so as to withdraw the blocks or projecting; portions of the follower from the mold prevliminary to the outward movement of the plate 82 and follower to admit of the bricks being ejected from the mold upon the pallet in the discharge of the bricks from the machine in the manner herein stated.

The endless carrier receives a motion similar to the rotary table, e. it starts slowly, has its movement accelerated, and is then 7rra-dually retarded untilit nally comes to rest.
