PATENT oFElcE BRICK OR; BLOCK CASTING Robert SaReed; ThreeRiversyMichi Application October 18', 1946,, Serial'No. 7045246 invention rd ates; to improvements in brick or block casting machines.

The principal objects of this invention are:

First, to provide a machine for' casting inadividualbricksor buildingblocks-with a vibratory packing systemw-hi'ch' is both compact-,- and easily operated.

Second, to provide a brick casting machine in which there are no rotating or reciprocating partsinthe vibratory system to" become'worn or get outof order: v 7

Third, to provide a brick casting machine-in which" the vibrating machinery and? controls therefor are efiectivel'y' enclosed and protected against" contactwith" mortar and water.

Fourth, to providea casting machine in which cast? a plurality ofbricksonay simpl'e removable 2 'pallet"so that the handling and the curing of the bricks after castingfisfacilitated;

Sixth, to provide a; casting machine which is easily adaptable to makingeither a; plurality of bricks or" one or more-*larger'b'locksi Other objectsandadvantages pertaining tothe details and economies attire-invention will be apparent from a consideration'ofjthefol'lowingdescription. The drawings, of" which there are two sheets, illustrate a; preferrediorm of casting machines. v a

In the drawings the reference numeral I in dicates the base of my casting machinewhich consists of a welded angleiron frame and sheet metal panels enclosing suitable power supply and. regulating mechanism at 2 to be more particularly described presently. A. heavy metal plate IA welded. to the top of the" frame adds rigidity to the frameandprotects-'the-regulating mechanism; r g p MOu ted ctr-themse- Fon fourbolteand coil 55,-.

4:.Glaims... (01. 25-41) 2; springs 3 are a;- pair of channel support members 4- which form supports for the side plates 5 connected thereto by the brackets 6. The side plates have welded thereto vertical angle members- I which extend above the center of the side plates and form supports for the ends ot abacking plate 8. Anglebrackets 9 (see Figs. 1' and 5') secured tothe insides of side plates 5 form supports fora bed; plate [9 which extends horizontally between the side platesforwardly of" the vertical angles 1 The bed plate H) has two or more wooden riser bl'oclss H secured to its upper surface which form supports for the removable pallet H freely supported thereon.

The backing plate 8 is vertically slotted. as at 13* through approximately theupper half of its width'to pass eight divider plates M which extend forwardly 'across' the top surface of the: pallet I 2. The rear-ends ofthe' divider plates. are secured to and spaced along a threaded spacer bolt I5; their spacing being determined by I6 threaded: on the bolt on each side of each divider plate: The spacer. bolt i5 is supported at its ends-in guide plates IT which define hori-- zontal sI-ots-l=8 which the spacer: boltis arranged to be translated forwardly and backwardl-y. The forward edges of the guide plates [T- are flanged'in-wardly as at l9 and securedto the opposite sides of the vertical angle members I from the backingplate' 8. Secured to each end of thespacer bolt l 5 are levers having their lower ends pivotally mounted as at 2| to theside plates 51. The divider plates are thu ar'-- ranged to reciprocate; forwardly and backwardly through the slots l'3-in the back plate. and over the pallet t2 asindicatedbythe dotted lines at 22 in Fig. 3;. by movement-of the levers 2'01 and bolt l5.

Connected to the levers 2|): intermediate of the. ends thereof: are a pair of links 23 which:

extendforwardl y of themachinezand haveithein front ends secured tothe bottom: of front: levers 24 as at 25: The levers 2'4 are pivotal lysupported as at 26' on the forward corners of the sidepl'ates 5 1 The front-levers 2'4 have anangul-ar shaped cross section at their upqoenerm'l's and are secured to a front plate 2 which is vertically slotted as at 28 corresponding to the slots the backing plate 8 'Ihehandleidsecured to the frontplate by the Z-shaped-brackets 30- is operable to tip=the front plate 2:1 and front: levers it'forwardly about the pivotszt. Forward motionofthe-handle 29 wil1 throw the links. 23 andthe rear levers' Z'W'tothe rear of the machine sim-l-fl-taneousl-y causing the spacerv bolt to be:

moved to the rear of the slots is in the guide plates and drawing the divider plates through the slots I3 away from the pallet I2, thus leaving the bricks 3| freely supported on the pallet and spaced so that air may circulate therearound for proper curing of the mortar.

The mechanism for vibrating the bed plate In and the pallet 12 carried thereon is most clearly illustrated in Fig. 3 and consists of supporting brackets 32 secured to the under side of the bed plate and directlyconnected to the middle of the longitudinal springs 33 by studs 34 which extend downwardly to the ends of a transverse spring 35. The ends of the longitudinal springs and the middle of the transverse spring are connected to lower brackets 36. The support brackets 32 have clamped therebetween a series of laminated core plates 37 which are slightly spaced from and cooperate with a series of laminated armature plates 38 clamped between the lower brackets 36 to complete a magnetic path 1 larger casting cavities for making larger blocks. Obviously variation in the size and spacing of the front plate, backing plate and divider plates 1 will provide a varying number and size of bricks or blocks cast.- The machine is made almost enfor flux set up by a magneticcoil not shown.

The'coil is connected through anelectrical cable 39 (see Fig. 1)'to the power supply and control mechanism 2 in the base of the machine. The control mechanism includes a rectifierand rheostat, for converting alternating current to a pulsating current of variable amplitude to cause the core 31 and armature 38 to be attracted toward each other once during each cycle of the alternating current thus vibrating the bed plate l0 and the pallet carried thereon. Varying the amount of current in the coil by adjusting the rheostat knob 40 changes the amplitude of vibration making the machine quickly adaptable to various weights of aggregate. A foot operated lever or pedal switch 4| connected to the control mechanism by electrical cables 42 is provided so that the operator of the machine may have both hands free tomanipulate' the handle 29. Sheet metal panels 43,.clamped between the underside of the bed plate andthe brackets 32 entire- 1y enclose the vibrating equipment and protect it from mortar and dust. The details of the control'mechanism'2 and vibratin mechanism are not describedor illustrated ;in greater detail as these partsare standard commercial products sold under the trade name of Syntron by the Syntron Company of Homer City, Pennsylvania.

Inoperation the handle will be'drawn forwardly exposing, the riser blocks H;so that a new pallet [2 may be placed thereon. The handle is then thrown forwardly drawing the divider plates forwardly over the pallet and into engagement with the slots'in the front plate 21 ;to

maintain thevertical alignment of the dividers. A quantity of mortarmay then be poured into the spaces between the divider plates suflicient,

well known that light weight aggregates must 7 be vibrated with less amplitude than heavy aggregate which requires a longer travel or amplitude of vibration to be compacted properly. The

speed and advantages of vibratory casting of cement mortar are well known and need no further description and the molding operation can be completedin a very short time after which the operator will again draw the handle forwardly simultaneously withdrawingthe divider plates and permittingthe removal ;of the pallet: and the completed bricks. The,- smooth pallet,

tirely' of standard plate and angle stock and so is inexpensive to manufacture.

Having thus described" my invention, what I claim as new and desire to secure by Letters Patent, is:
