MOLD-HANDLING APPARATUS.

Specication of Letters Patent.

Application led January 8, 1921. Serial No. 435,853.

T 0 all 'zo/1.0m t may concern.:

Be it known that I, EDWARD D. CARY, a citizen of the United States of America, residing at New York, in the county of New York and State of New York, have invented certain new and useful improvements in Mold-Handling Apparatus, of which the following is a specification.

This invention relates to a mold handling and conveying apparatus, designed particularly to be used in conjunction with any type of brick molding machine., and adapted in use to direct the molds into proper position with respect to the brick machine, to thereby receive the material, convey such molds from the brick machine and discharge the brick from the molds, direct the discharged brick to a point of discharge, convey the empty molds to a sander in which the interior of the mold is sanded to prevent the brick material sticking thereto, and deliver the sanded mold into proper position with relation to they brick machine, thus completing a cycle of operation.

The improved machine is entirely automatic in its operation with all parts driven, if preferred, from the motive power of the brick machine, and each and every part of the improved apparatus turned with relation to every other part and operated entircly without the use of chains, gears, belting or the like with the advantage of avoiding irregularity of operation and the frequent necessity for repair and adjustment necessitated by such particular driving' means.

In the drawings Fig. 1 is a side elevation of the improved apparatus.

Fig. 2 is a longitudinal central section of the same.

Fig. 3 is an enlarged transverse' section on line of Fig. 1.

Fig. l is a rear end elevation of the machine.

F ig. is a perspective view showing the operating means rfor the various moving parts of the apparatus and for compelling the travel of the mold.

Fig. 6 is a perspective view showing the mold secured upon the sanding wheel.

Fig. 7 is a detail perspective showing the operation of the feeding fingers.

Fig. 8 is a transverse section of the same.

The apparatus comprises a main frame 1 which for the sake of the present description may be said to comprise an upper trackway 2 and a lower trackwayY 3. A brick machine 4 of any usual or preferred type is mounted so as to discharge the material therefrom onto the upper trackway at a particular point to be hereinafter referred Patented Aug. s, i922.

to, and the respective parts of the apparatus to be described are arranged with more or less particular relation to such brick machine.

The shaft 5 is mounted in suitable bearings on the upper trac-kway in rear of the bric-k machine, considering the direction of movement of the molds, and on this shaft areV fixed spaced discs 6, having aligned recesses 7 of a size and shape to receive the mold. The'discs together constitute whatwill b-e hereinafter termed the mold positioning wheel, and the recesses, preferably four in number and arranged in 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 relatively offset from `the diametric line as shown. The upper trackway 2 in advance of the mold reversing wheel is in the form or 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 end of the conveyor between the discs of the mold reversing wheel is on a plane llower than that of the trackway beneath the brick machine, so that as the molds are reversed by the wheel and the bricks delivered therefrom on the pallet vboard support, said support and bricks will also having a roller bed Q0 by which the mold is directed back onto the lower trackway Bof the main frame. 1

The molds` are carried lengthwise1` the `lower trackway to the forward end o the mainframe and are there delivered to a sandingwheel ,21 Vthrough which they are sanded and delivered to the positioning wheel herein beiore referred to.` llie `mold and various wheels such as `the positioning wheel, `reversing wheel, discharge wheel and sandingr wheel are operated automatically and givena periodic limited move` ment in each `step by step operation l of the machine, and the mechanism vfor performing these` various y operations will now be described. which is` given a reciprocating movement through suitable connection with the driving mechanism of the brick machine.y or in`de` pendent power may be desired, rocks a shaft 23 supported in suitable bearings in the main frame between the upper and lower trackways and `preferably beneath the brick machine. An operating bar 2Liis movably supported upon a traine element 25 andcarries, by means oli uprights 9,6, pivotally mounted pawlsiQ, l28 and` 29. Tliesefpawls are each formed on their lower sides to presentihooks 30` andwith extended nose portions 3l in advance oi' the hooks.` rlllhe respective `pawls 27, QBand 29 are arranged adjacent the positioning,` reversing andi discharge wheels, and such wheels are provided with diainetricallyg opposed arms 32 having lateral pins 33to lie-engaged by the hookportions 30 of the;par\vls. `The lhan 24-` is provided with `a lateralA pin ll-extendng through slot `35 in the frame bar 25 and `connected by afliiik 36 with antarin 37 cured to the rock shaft `23. As the shai't 23 is rocked in the operation of the device, the

respective. pawls 27, 28 and 29` will engage.

The positioning, reversing and discharge wheels are thus advanced by a step by step movement through a` quarter or a revolution at each movement. A corresponding pawl 38 supported in a traine bar 3 9 and operated by a link llllro'm zi-rind( is arranged to enthe pins ell. or the sanding wheel, to thus simultaneously advance` the sanding wheel in a step by step movement through a onequarter revolution.`

upper trackwaji/,the continued movement of the links under theqoperation oit the rock shaft 23 will `move the elevated dogs in the direction oi'? travel oit the molds. These dogs vare.positioned, whenat their extreme limit et. rearward movementin i'ear ofthe innermost edge oit-the lmold in lthe `positioning wheel next the :brick machine, so that said mold will., inthe operation of the parts. be torcedlii-oin the positioningwheel and delivered beneath the brick machine. v

The trai-elr ofthe inolds along the lower trackway 3 is also provided for through a series `oil dogs 48 pivotallysupported bef tween bars .l-Qniovablyzmoiinted in the lower ends elevated above the trackway and operated through links `50 las described in `connectionu.with the y dogs 45. The links `50 are actuated through a rod `5l "connected by bars 52 with"I the` arm' 37 and with the corresponding'arm 5? at the op- 1' posite end of the `rocksha'tt 23.` The fmolds lare thus given a step by step movement' `lengthwise `the low-er'trackway, the reverse movement oitthe linksl'O permitting the dogs -to drop to ride-beneath the next moldr to be engaged, will be obvious.

The end of thelower trackway adjacent lll) the sandingwwheel terminates in a downi wardly inclined section 54 bywhichthe molds are turned and directedonto the-.sanding wheelwith their open ends .or `'faces against said wheel. The sanding wheel is provided.

`with transverse abutments and 56 between which. thefmold iszfreeeived, and gripping ,members are arranged to hold the n10-ld, in 13@ proper position on the sanding Wheel during movement of said Wheel. rlhese gripping members comprise arms 57 having hook ends 5S to engage over the ends of the mold, the opposite end of the arms having rollers 59 to bear upon lixed trackvvays 60 to press the hook ends the arms into holding relation with the mold. s the mold reaches the uppermost position on the sanding Wheel it is free of holding connection with the Wheel, as the previous termination ofthe trackvvays 60 permits the arms 57 to gravitate to a release position. The discharge position of the sanding Wheel is immediately adjacent the positioning ivheel, there being arranged intermediate the sanding Wheel and positioning Wheel spaced lingers 6l, up Which the mold is forced by the movement of the sanding Wheel, and the bar 56 to the plane of the recess in the positioning Wheel. A mold resting upon these fingers is of course forced into the positioning Wheel recesses by the next or succeeding mold of the sanding Wheel, as ivill be apparent.

The molds are forced from the reversingI Wheel through a plunger 62 slidably mounted 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 reversingr Wheel next the arms of the discharge Wheel,v the ejecting movement of the plunger being` provided through Contact of the advancing mold from the brick machine. There is a plunger on each disc, each cooperating With tivo slots, so that after ejecting movement the turn of the Wheel positions the plunger for the succeeding operation.

The shaft 65 on which the sanding Wheel is rotatably mounted is hollovv and formed with a series of openings 66 ivithinthe plane of the vvheel, the shaft communicating With the sand supply, so that sand is delivered into the mold when in lowermost position on said Wheel for sanding purposes, the sand accumulating in the Wheel being readily distributed, that is shakeninto and out of the moldv during movement of the sanding Wheel in order that the mold may be propei'ly sanded.

r he mold is of usual form here shown as comprising a box like member 67 having brick or other compartments 68. and provided with end extensions 69 which may or may noiy be solid or otherwise built up, the extensions providing` the additional length of mold necessariY to permit suchmold to be properlyv supported in the recesses and arms of the respective Wheels, While having the brick or other molded material arranged Wholly between the discs forming :such Wheels. This is essential as in the use of the reversing Wheel the molds are carried from said Wheel onto the arms of the ldischarge Wheel and picked up leaving the .versed onto the conveyor l1.

brick on the pallet in contact 'with' the i 1n the operation of the device, the posi-y tioning Wheel, receiving in'its successive recesses the molds from the sanding Wheel, deliver suchl molds onto the upper track- Way 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 reresting on the pallet are thus discharged and moved off on the conveyor by gravity7 to a point of discharge. Themolds are picked up by the arms of the discharge Wheel and delivered onto the mold conveyor, and so on to the vlower trackvvay. The molds are fed ,in succession lengthwise the lower trackway to the sanding Wheel, properly7 sanded and delivered to thepositioning Wheel, thus completing the cycle of movement.

It will be noted particularly that all parts The bricksof the lapliaratus herein described are operi ated `Without the use of chalins, belts, sprockets or the like and that every movement is coordinated with every other move- `ment so that it is impossible for the machine to get-out of time in its respective Z operations, and also the necessity for repair andy renewal incidentl to ordinary modes of ydriving mechanism is obviated.
