BRICK HANDLING APPARATUS Tlf-1 United States Patent BRICK HANDLING APPARATUS John Foster Oury, Northlake, Ill.

Application September 10, 1956, Serial No. 698,762

6 Claims. (Cl. 214-653) My invention relates to brick handling apparatus and has particular reference to a mechanism which may be used in the handling of bricks, mortar, lumber, and the like, in building construction, both for unloading from a platform truck or for the purpose of handling building material and hoisting it to a position where it can be deposited upon a scaiord where workmen, such as bricklayers, carpenters, and the like, can have the material close at hand for use in embodying it in the structure under construction.

Another object of my invention is the provision of a power operated vehicle upon which a brick handling and hoisting mechanism can be mounted and which may be used in picking up bricks which have been stacked .L

in the form of a cube or the like, and moving such stacked up bricks from one point to another for convienience in building, storage, and the like, which can also be used for lifting such a cube of bricks and depositing it upon a scafford adjacent the bricklayers without the necessity of carrying the bricks up ladders and the like.

Another and further object of my invention is the provision of a brick or block handling apparatus which embodies an open sided squeeze frame which can be placed in position to exert pressure upon the lowermost layer of a cube of bricks, blocks, or the like to provide a pallet which supports the bricks above the lowermost layer forming the pallet, and in which a cube of bricks can be transported from the ground, storage place, or the like, onto a scaffold where they are within easy reach and access of the workmen. Y

Another and further object of my invention is the provision of a brick handling apparatus which when curved over a cube of bricks or blocks automatically positions itself over a cube of bricks in such manner that the thrust of the squeeze frame is properly alined With respect to the brick cube and that the gripping ngers engage the bottom row of bricks of the cube of bricks in a plane below the center of such row of bricks so that a secure pallet is formed to sustain the weight of the cube of bricks, without any attention, particularly upon the part of the operator.

' Another and further object of my invention is the provision of a brick handling apparatus in which the squeeze frame is properly positioned over a cube of bricks regardless of the uneven condition of the ground upon which the bricks may lie or the canted position of the vehicle because of uneven ground upon which it rests so that the application of force through the squeeze frame to the cube of bricks is in the proper alignment to provide a stable cube without danger of the bricks Y falling, or dropping out of a cube onto workmen resulting in injury or the like to such workmen.

A further object of my invention is the provision of lifting and handling mechanisms to a well known type of'vehicle for the purpose of handling bricks, blocks, mortar, and the like, on the job to eliminate the manual handling of such material which has been the practice generally followed in residences, store buildings, and the like, where such buildings are usually three stories in height but may cover a' substantial area of ground.-

stub tubes

7S and 79 and 81 and 82 are moved in and out of the guide tubes 70 and 71 thereby moving the

iingers

38 and 95 into and out of gripping position with the cube of bricks or blocks as the case may be.

A carriage for the squeeze frame is provided which comprises a pair of short channel sections 111 and 112 having slide blocks 113 welded to the back of the webs of the channel sections 111 and 112 and which are fitted into the channel rnembers'S and 66 which with the cross member et; comprise the upper section of the mast construction with an angle 114 being welded to the edges of the members 111 and 112 and spanning the space therebetween which angle has pairs of spaced extensions 115 and 116 and 117 and 118 thereon between which the ends of the brackets '72 and 73 are positioned, each of the

brackets

72 and 73 having slotted openings 119 therein through which bolts 12%) pass and which afford a loose connection between the squeeze frame and the squeeze frame carriage so that when the squeeze frame carriage is dropped over a cube of bricks the carriage may cant slightly in order to properly position the squeeze frame about the cube of bricks as will be more fully described hereinafter.

A cross angle 121 is secured to the

brackets

72 and 73 which has connecting

angles

122, 122 at the forward face thereof to which a backboard 123 is connected at its upper edge, and which is secured near its lower edge to one of the cross braces 100 which connects the

brackets

72 and 73. The backboard 123 spans the space between the

fingers

38 and 95, and prevents bricks from dropping rearwardly of the squeeze frame onto some of the operating parts which bricks may come from the courses above the lower-most courses of bricks forming a pallet during the movement of the carriage or if the mast shouid become backward over the machine to such a degree that the bricks would have a tendency to slide oit the cube. Mounted upon the backboard 123 and is secured to the backboard 123, vertical angles 12451, 124e welded to the angle 124 through which

bolts

125, 125 pass through slotted openings in the angles 12411, 124e and have

wing nuts

126, 126 thereon which provides for the vertical adjustment of the angle 124. The angle 124 serves as a gage when the squeeze frame is placed over a cube of bricks to properly position the fingers 88 and 99 with respect to the lowermost courses of brick so that the lower edges of the

ngers

88 and 90 are substantially even with the underside of the lowermost course of brick thereby making sure that the fingers are always in proper position to grip the brick at their lowermost portions. The gage 124 can be adjusted up and down to conform to the height of a cube of bricks determined by the number of courses of brick usually four, preferably placed in edgewise relation with each other and providing for variation in height of the bricks or blocks which are being handled and which may vary slightly in width or dimension.

Arms

127, 127 are provided having an angle 128 on their outer ends which angle 128 may be dropped over the forward edge of the uppermost course of bricks so its depending ange 129 prevents these bricks from becoming displaced due to vibration or a rocking movement of the mast if the vehicle passes over rough ground while the cube of bricks or blocks is being transported. Sideboards (not shown) may be provided which can be mounted on the fingers 8S and 95B to prevent loose bricks, making up the upper courses, from sliding loose it desired, although in normal operation of the device, I have not found such sideboards to be necessary.

A U-bracket 13) is mounted to the upper tie bar 68 and has an axle 131 mounted therein on which a pair of grooved pulleys 132 and 133 are mounted over which Athe hose 1193 and d pass so that the ram 96 may be operated when the squeeze frame is in elevated position shown in Figures l and 2. A sprocket wheel 134 is also mounted on the axle 11 and over which a chain 135 passes, which chain is anchored at one of its ends to the agle 114 forming a part of the squeeze frame carriage and at its opposite end is anchored to a tail bracket 136 having legs 137, 138 which are welded to the cross frame member 12.

The squeeze frame and carriage therefore is raised and lowered by a hydraulic ram comprising a tube 139 which is connected to the bracket 136 secured to the cross 4frame member 12, with a connecting member 142 for the tube having a pin 143 extending therethrough.

A piston 144 is mounted in the tube 139 and is connected at its upper end to a cross member 145 forming a part of the bracket 130 so that an upward thrust of the piston pushes the top section of the mast upward and as this mast section travels upward, the squeeze frame carriage and squeeze frame, is raised at the same time. One end of the chain 135 is anchored to the frame of the vehicle while the other end is secured to the angle 114 forming a part of the squeeze frame carriage and as the top section of the mast is raised the squeeze frame and carriage are raised by the chain in a power ratio of two to one, and also at a rate of speed travel of two to one, that is the squeeze frame carriage and squeeze frame travels upward twice as fast as does the top section of the mast.

Hose pulleys 146 and 147 are mounted on brackets 14S, 148 which are secured to the cross frame member 12 with the hose 103 and 164 running around the

pulleys

146 and 147 respectively through which the hydraulic fluid is forced into and exhausted from the hydraulic ram 96, controlling the operation of the squeeze frame. The hydraulic tube 139 has a connecting member at its lower end to which a hose 150 is connected through which hydraulic uid is conveyed to and away from the tube 139 forming a part of the hydraulic ram.

"For the operation of the various p-arts of the device hydraulically, a pump 151 is provided which -is operated by a belt 152 passing over a wheel 153 mounted upon a power shaft extending outward from the engine 26. Y

A master hydraulic valve 154 is provided having a pressure line 155 leading therefrom to the pump 151 with the

lines

103 and 104 both leading to the master vaive 154 which are controlled by a three way valve forming a part of the master valve, 154, by a handle 157 which controls the flow of hydraulic fluid to and exhaust from the squeeze frame ram 96 so that the operator, while moving the control handle 157, can admit fluid under pressure through the hose 103 into the squeeze ram 96 which draws the

fingers

88 and 90 together to exert pressure upon the lower layer of bricks forming a cube which pressure is allowed to remain constant during the handling of the squeeze frame and cube. A pressure gage 158 is provided which registers the pressurev through the pressure line 103 so that the operator is advised as to the amount lof pressure being exerted upon the squeeze frame and very quickly learns to know what pressure -to apply to the squeeze frame in order to provide a solid pallet for supporting the balance of the cube of bricks. The tilt rams

cylinders

62 and 63 have one of their ends connected to a hose 158 which has a connecting hose line 159 leading to the master valve 154 and to a three way valve which `is controlled by a handle 160 with a second hose line 161 being provided which hose line connects the opposite ends of the ram cylinders 62 `and 63 together and in turn has a line 162 leading to the master control valve 154, this particular portion of the valve being a three way valve by means of which pressure can be admitted into the

power ram cylinders

62 and 63 to move the mast in a backward and forward direction on its pivotal mounting, partially for balance purposes, and also to move the squeeze frame far enough over Va scaffold to deposit .a cube of bricks thereon after Y 7 4 t the deberias been, elevated te a sud'eie'nt height te :dear the scalolding and the vehicle moved in close enough sbjtha't `when' the squeeze frame is lowered, the cube of brick will rest upon the scaffolding. l

jAn outlet' pipe 1'64 is provided which leads from the Y mster' valve 154th an dil reservoir 165V with .fr/supply line' V166 leading from the reservoir 165 to the pump 151. The hose 150 leads tothe master valt/e154 and to aT two way vvalve"controlled .by a handle 153 so th-at'pressure admitted' through the valve passes to the tube 159k formingv apart ofthe elevating ram. and the upper lsecj VtionY o'f the r'an'i is moved upward carrying with it the squeeze frame tothe desired height necessary to a par` ticuflar operation which height'I have found to be something like fourtee'rfeet, forv normal operations' which perthe squeeze frame' to be lifted to a' height approximately twelve feet, which is adequate for the deposit of Vlbricks, mortarg-.and the'like, upon a sc'atfold ordinarily u'sed in one and two story buildings.l YWhen the operator Y desires' t'o' lower the squeeze' frame, he operates the two way valve through the handle 163,'thereby allowing ythe hydraulic fluid to pass through'the pipe 15@ into the return pipe 164 Lto the reservoir 165. The weight of the `VsqueezeV frame upon the piston 144 forces the fluid from these pipes and the operatorby controlling the degreeV of openirigjofV the two way Valve controls the rate of decent' of the squeeze frame whether the squeeze frame Y Yis loaded with a cube of bricks or whether it is empty and lowered forV the purpose of picking up a cube of bricks.

" In the operation of the device,V the operator takes hisV position between rthe projecting steering rods d at the j rear of the machine and4 starts the motorV 26 and through the operation of the clutch mechanism connects theV transmission mechanism with the traction wheels 17Y and i8 and" moves the vehicle't'o a. point where the tractionV wheelsy 17 and 18 are positioned 'on eachside of and spaced from a pre-formed stacked cube of bricks or blocksWh-ichthavepreviously been placed in position Vpreferably with bricks comprising the Vlowermost course 1 wise position in abutting Vend-to-end relation with each Vother and the' additional courses above the pallet course arranged'in somewhat the same manner, preferably three inrnumbe'r.V Il have found that a cube of brick which comprise about four inY endlto-end relation with Ye'ach other and ten'in side-to-side relation'rnaking atlayercomprisirrg forty lbricks and four courses in height'rnakes a desirable sized' cube,'such a cube comprises one hundred sixty bricksV aindjweighs approximately 1,000 pound'sfand is a desirable size to handleand can be both transported and liftedV very easily and deposited upon a scaffold or any other platform .asnrayb'e desired. Y

I-f the bricks are of'smoothttexturefparticularly with respect to the bricks formingthe lowermostor pallet course,y strips of corrugated'paper may be placed between t the adjacent ends ofthe brick providing arcus'hion and a means of forming the pallet more', rrnly when pres-V sure is ,appliedthereto through the lingers 88 and 9i) so that thepallet islirmly formed and theibricks are not apt to dropout of it. VIf thesurfaee texture of the bricks is extremely smooth or if the surface is unusually rough, it is necessaryto bring the major portion of the contacting surfaces into intimate relation with each other or to supply Asome medium between ,the surfaces of the bricksv to prevent" slippage so lthat sucient friction is formed to hold thejptallet as a unit and also to support the other layers of bricks'suplerimposed thereon.Y f

`As' the device is moved over a pallet of'brick, the operator, by nrovin'gV the mast forward or backward, Vpositions the gripping fingers on each side of the pre-formed cube with the backboard 123 being on a line so as tojbc fairly close to theV sideY of the brick cube adjacent the' ',nia'chine, in which position the squeeze frame and gripi ping'iingers' are lowered over the cube until the angle 124 engages the topof the uppermost layer-of bricks form- Y -ing the cube adjacent the backboard 123V which gage Y has prei'lio'uslyY been adjusted to a proper distance to position the

fingers

88 and 90 against the lower portions of the bricks forming the lower or pallet layer and in 1 this position, the weight of the squeeze frame is Vsupport;- ed by the angle 124l which y'automatically places the iin- '.'ge'rs SS and 90 in plane parallel withV the Vlower portions ofVK the bricks making upithe pallet co-urse thereby 'ac curately position-ing the

fingers

88 and 90 relative to the lowermost course of brick regardless of whether the cube Y squeeze frame accurately adjusts itself to the cube of bricks. the cube of bricks, the operator, through the rnanipula-Y tion of the valve handle 157, appliespressure through kthe hydraulic'ram Vto the squeeze frame exerting pressure upon the lowerinost course of brick to form a rm pallet. The operator, from experience, learns what presj sure is necessary to secure this result and watches theV pressure being 'applied through the gage 158l until adequate pressure is appliedt'o Vthe lowerrnostll course of brick to form a pallet. Y Y

After the squeeze frame has been adjusted to the cubeV of bricks, the operator by admitting pressure Lto the ram tube 139 raisesV the upper section of the mast telescopically with respect to the lower section until the cube of bricksis free of the ground, and the vehicle can then be moved to any desired position and steered bythe oper-` ator exerting pressure upon the guide handles to guide the vehicle, or through the control of the power clutches leading to the traction wheels he may guide it, to the desired point and'when such point is reached, for example, adjacent the scaffold of a building, additional pres-V sure is admitted to the lifting ram which li ts the squeeze frame including a cube, of brick to a line above the scaiold'upon'whi'ch the Workmen are employed in the Y laying of the brick, and the vehicle moved adjacent the scaffold untilthe squeeze frame' and cube of brick are overthe scaffold in which position the mast may be tilted forwardlyifnecessary to properly position the cube of brick over the scaffold in which position the squeezeV frame andy cube of brick are lowered until the brick rests upon the scaffold, and the operator thereupon releases the pressure of the hydraulic ram holding the brick together, the fingers freed of the cube of brick and the squeeze frame and fingers can be either lifted over the cube of brick or the entirer'machine can be backed away from the cube leaving it deposited upon the scaifold. As the squeeze frame is positioned around a cube of brick, the angle 12S is dropped down so that it engages the forward edge ofthe upper layer of bricks to prevent these bricks from slipping out of the course,

I have found that a mast construction having a lowermost section approximately eight feet in length and the uppermost sectionbeingjof the same length, provides aV mast of suihcient height so that a lift of fourteen feet can be obtained with the squeeze Vframebeing lifted at least twelve feet which is suiiicient height to deposit brick and lthe like onto the average scaffolding which is cornmorily used in Ythe construction of one and two story brick buildings, stores', residences, and the iike.

`Itwill also Vbe understood that the device may be usedA for lifting mortar to a position for useby workmen upon Afterrthe squeeze frame has been adjusted to.

a scaffold by the addition of a container or bucket to the squeeze frame and likewise bundles of lumber, shingles, and other building mterials can also be layed across the squeeze lingers and elevated and delivered to workmen on a scaold or at some position above the ground.

While i have described more or less precisely the details of my construction, i do not wish to be understood as limiting myself thereto, as l contemplate changes in form, the proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my invention.
