The" apparatus 'comprises a main frame 1 vrvliicli for the nsalie of the present description may be'said to 'comprise an up r trackway 2 and alower trackway 3. A rick ma- 1150 chine f1 of any usual or preferred type' is nio sof as to discharge the material y therefrom the upper trackway at .a armani' peine a be hereinafter refm fw, tive parte 'of the apparatus te are arranged with 'more or less Amachine, considering the direction of movement of the molds, and on this shaft are fixed spaced discs 6, having aligned recesses 7 yof a size and shape to receive the mold. The discs together constitute what will be hereinafter termed the mold positioning wheel, and the recesses, preferably four in number and arranged 1n diametrically opposed pairs, receive the mold and deliver the same into a position to be moved beneath the brick machine.

. A shaft 8 is mounted in the upper trackway in advance of the brick machine on which is arranged spaced discs 9 together constituting what will be hereinafter termed the mold reversing wheel, these discs being formed with mold receiving slots or recesses 10, also preferably four in number rclative- 1y offset from the diametric line as shown. The upper trackway 2 in advance of the mold reversing wheel is in the form of a downwardly and forwardly inclined gravity conveyor 11, made up of side supports and a series of freely rotatable rollers 12 constituting the bed of such conveyor. This conveyor extends between the discs 9 of the mold reversing wheel and terminates at the opposite end for a proper discharge. The en of the conveyor between the discs of the mold reversing wheel is on a plane lower than that of the trackway beneath the brick machine, so thatas the molds are reversed made up of spaced arms 13 mounte upon a shaft 14 supported on the frame work in the plaire of the upper trackway, the arms 13 picking up vthe molds from the conveyor and delivering them to a lateral mold conveyor 15 also made up of a roller bed 16 by which the molds are conveyed laterally of the main frame, as shown in Fig. 4. The mold conveyor extends some distance to one side andv arranged be 0nd the end of such conveyor and pivotal y supported at a point above the same'is a swing arm 17 having a lateral or a receiving end 18, which as the end of the mold rides olftheA mold conveyor reclined chute 19 also having a roller bed 20 bywhich the mold is directed back onto the lower trackway 3 of the main frame.

The molds are carried lengthwise the. lower trackway to the forward end of the main frame and are there delivered to a sanding wheel 2].` through which they are sanded and delivered to the positioning wheel hereinbefore referred to. The mold and various wheels such as-the positioning wheel,"reversing wheel, discharge wheel and sanding wheel are operated automatically and givena periodic limited movement in each step-by step operation of the machine, andlthevmechanism for performing these various operations will now be described. An operating rod 22 which is given a reciprocating movement through suitable connection with the driving mechanism ofithe brick machine, or independent power as may be desired, rocks a shaft 23 supported in suitable bea-rings on the main frame between the upper and lower trackways and preferably beneath the brick machine. An operating bar M isl movably supported upon a frame element 25 and carries, by means of uprights 26, pivotally mounted pawls 27, 28 and 29. These pawls are each formed on their lower sides to present hooks 30 and with extended nose portions 3l in advance of the hooks. The respective pawls 27, 28 and29 are arranged adjacent' the positioning,l reversing and discharge Wheels, and such wheels are providedwith diametrically opposed arms 32 having lateral pins 33 to be engaged by the hook portions 30 of the pawls. The bar 24 is provided with a lateral pin 34 extending through slot`35 in the frame bar 25 and connected by alink 36 with anarm 37 secured to the rock shaft 23. As the shaft 23 is rocked in the operation of the device, the respective pawls 27, 28v and 29 will engage the particular pin 33 of the positioning, reversing and discharge wheels and impart a predetermined movement, as one quarter revolution to such wheels. The nose portion31 of each pawl is of such length that following a predetermined movement of the wheel, the nose portion will overlie the next pin 33 of the particular wheel to be engaged, sov that, as the shaft 23 is rocked in the opposite direction, the pawls will advance from the pin previously engaged and by the nose en agement of the next adjacent pin caused to ride onv said pin to the new position, that is with thehook 30 engaged with such advanced pin, whereupon on the rocking of the shaft 23 in the opposite direction, the Wheels are again given aI quarter turn. The positioning, reversing and discharge wheels are thus advanced by a step -by step movement through a quarter ofV a revolution at each movement. A corresponding pawlr 38 supported in a frame bar 39 and operated by a link 40 from arm 37 is arranged to engage the pins 41 of the sanding wheel, to thus simultaneously advance the sanding wheelin a-stepby step movement through a one quarter revolution.

Secured upon the rock shaft 23 are spaced a-rms 42 connectedv at the upper.I ends by links 43 toa depending projection-44 ofk a dog 45 pivotally supported at 46 between frame bars 47 forming part of the upper trackway within the plane of the positioning wheel. The dogs 45 are, by means of the links 43 and their connection below the pivot ofsaid dogs, adapted to vhave their forward orl free ends elevated above the plane ofthe 'frame bars 47v for initial movement of the links 43 in one direction, and as the frame bars* 47 are slidably mounted-in the upper trackway, the continued movement of the links under the-operation of the rock shaft 23 will move the elevated dogs in the directionoftravel of the molds. These dogs are positioned when at their eX- treme limit of rearward movement in rear of' the innermostI edge of the mold in the positioning wheel next the brick machine, so that said mold will, in the operation-of the parts, be forced from the positioning wheel andvfdelivered beneath the brick machine.

The travel of themolds along the lower trackway 3 is-also provided-for through a series of dogs 43v pivotally supported between bars 49 movably mounted in the lower rtrackvvay and operated through links 50 as described in connection with the dogs 45. The links 50 are actuated through (a rod 51 connected by bars 52l with the arm 37 and with the corresponding arm 53 of the opposite end of the rock shaft 23. The molds are thrusfgiven a step by step movement lengthwise the lower trackway, the reverse movement of the links 50 permitting the dogs to drop to ride beneath the next mold to be engaged as will be obvious.

The end of the lower trackway adjacent the sanding wheel terminates in a downwardly inclined section 54 bfy which the molds are turned and directed onto the sanding wheelf with their open en-ds or faces against said wheel. The sanding wheel is provided with transverse abutmeiits 55 and 56 between which the mold is received, and gripping members are arranged' to hold the mold in .proper position on the sanding wheel during movement of saidA wheel. These gripping members comprise arms 57 having hook ends 58 to engage over the ends of the mold, the opposite end of the arms having rollers 59 to bear upon fixed trackways 60 to press-the hook ends of theI arms into hold,-

y will be a relation-with1 themold.L yAs the `meid reaches the'upperme'slj." osition' on the sanding wheel 'it is'free o holding connection s with Athewheel as the previous termination #Tilof the trackways permits the arms 57 to 'vitate'A to a release position. The disarge position of the sanding wheel is imte y" adjacent thepositioning Wheel, there being arranged intermediate the sandgera 61, up which the mold is forced by the mpvementof the sanding Wheel, and the bar 56 yto the plane of the recess in the positioning wheel. A mold resting upon -fthese 'fingers is of course forced into the positioning wheel recesses by the next or silcceeding mold of the sanding wheel, as

arent.

The mo ds are forced from the reversing wheel through a plunger 62 slidably mounte upon the shaft 8 and held for reciprocating movement between guides 63. The forward end of the plunger is in position to eject the mold from .the recesses of the reversing wheel next the arms of the discharge wheel, the ejectin movement of the plunger being provided t rough contact of the advancing -mold Afrom the brick machine. There is a lplunger on each disc, each cooperating with two slts, so that after ejecting movement theturnofthe wheel positions the plunger for the succeeding o ration.

The shaft 65 onw ich the sanding wheel 'is rotatably mounted is hollow and formed 3with aseries of openings 66 within the plane of the WheeLthe-shaft communicating with ithesa'nd su ply, so that sandis delivered u-ifnta the melig w en n lowermost potsl'lton o3 sai wheel or san ing` rposes, e san accumulating in the wheel) tributed, that is,='shakeninto and out of the ymold-durin movement of the sanding wheel order t` Athe mold may be properly minded; l

' The moldis'of usual. form here shown as com icing Aa box like member 67 having bric for other compartments 68 and provided with end extensions 69 which may or may not be solid or otherwise built up, the extensions providing the additional length be rl supported inthe recesses and armlsilgh respective wheels, while havin -the brick or other molded material errang wholly between the discs formingy .-Such wheels. This is essential as in the use ofe the revers' wheel the molds are carried from saidwheel onto the arms of the discharge wheelfandpiked up leaving the brick on f 'mithin pallet in contact 'with' the gravity conveyor. Furthermore the extensions per- "mit` the handlingof the mold by the respectvevheels'without contact lwith the mate- In' operation of theA the posiing-vwheel andv positioning wheel spaced fin` being readily dis-l o mold necessary to permit such mold to tioning' wheel, receiving in its successive recesses the molds from the sanding wheel, deliver such molds onto the upper ltrackway along which they are forced to a position beneath the brick machine and receive the material therefrom. The molds as they leave the brick machine are provided with a pallet 70 by the operator and then delivered into the reversing wheel and reversed ontol the conveyor 11. The bricks resting on the pallet are thus discharged and moved off on the conveyor by gravity to a point of discharge. The molds are picked up by the arms of the discharge wheel and delivered onto the mold conveyor, and so on to the lower trackway. The molds are fed in succession lengthwise the lower `trackway to the sanding wheel, properly sanded and delivered to the positioning wheel,l thus completing the cycle of movement.

It will be noted particularly that all parts of the apparatus herein described are operated without the use of chains, belts, sprockets or the like and that every movement is coordinated with every other movement so that it is impossible for the machine to get out of time in its respectiveI operations, and also the necessity for repair and renewal incident to ordinary modes of driving mechanism is obviated.
