MACHINE For. nnncrmu' wrums or BRICK AND THE IKE.

Application filed February 2, 1924, Serial l lo. 690,160, and. in Great Britain February lti, 1923.

This invention has reference to machines for erecting walls of brick and the like and comprises improvements in the machine for this purpose set forth in my prior patent spec ifications Nos. 119,331 and 134,296.

The objectof'my. presentinvention is to provide a machine whereby the building of walls can be more expeditiously accomplished.

According to this invention the improved anachine comprises, in combination, upright structures, a cross member (or members) extending between and joining said upright structures, and brick laying vmechanism carried by and adapted to travel along said cross member, or cross members, the combination being such that the brick laying mechanism can be traversed to lay a course of bricks on each of four rectangular walls in succession.

Preferably the improved machine comprises in combination, two upright structures adapted to travel on rails, a horizontal structure or member joining said vertical structures, brick laying mechanism carried by and arranged to travel along said horizontal structure or member, and means for traversing the apparatus on its rails. V The arrangement and construction of the machine is such that the said vertical structurecan be traversed on rails laid on the outside-of two paralle'lwalls to be built, the'brick laying mechanism laying a course of brick on one of the walls during such movement, the brick laying mechanism then traversed on the horizontal structure to lay a course onfthe one of the end walls, the structures th again traversed on their rails in the opposite direction, a course of bricks being simultaneously laid on the other wall parallel to the rails, and the brick laying mechanism again traversed over the horizontal structure in the reverse direction th reby laying a course of bricks on'the other end wall It will thus be seen that a course of brick is laid on each of the four walls in succession,

after which the traversed member is raised to permit of the next course to be laid.

My invention further consists in various improvements in the brick laying mechanism and the features of construction which will be hereafter described and pointed out in the claims.

In order that my invention will be properly .understood 1 have hereunto appended seven explanatory sheets of drawings illustrating a preferred embodiment of my invention and operating mechanism therefor andwh'eren: Figure 1 is'an elevation of the machine, a part-- of the traverse structure being'shown broken away, but the length thereof willbe.

Referriugto the drawings A", A are two verticalstructures mounted to travel on rails 1, laidoutside of and parallel to two opposite walls to be built." I

(at least such as the breadth of the building to j H 6 6, 7-7, 8&8, Figure V B isa horizontal structure joining said vertical structures and C designates the brick laying mechanism carried by and arranged to travel along said horizontal structure The vertical. structures A A comprise two uprights suitablyoined at their upper-ends by girders 2 and provided with two wheels 3 at the base thereof. The, transverse member BfiCOHlPIlSQS two g1rders t providcd -v-.*itl-1 rails and a rack 5.

On said structure B is mounted a carriage 6, the wheels 7 of which travel on said rails.

A spur wheel 8 driven through suit-able gearing to be hereafter dcscribedis carried by the carriage and meshes with the rack '5.

wheel controlled by manually of a relative rotary movement.

*Said frames 11 are provided with a number of fiat faces 13 each having two spring actuated arms 14 for holding the bricks thereon.

The horizontally extending structure B is suspended at the four corners by ropes 15 which at one'sid'e of the machine pass directly to a winding drum 16 located at the upper end of the vertical structure A, while the ropes supporting the other side of the structure pass over the pulleys 17 at the upper end ofthe-structure A and thento the drum 16; I A square vertical shat-t 18 extends irom endtoend of the vertical structure A and on vertically of each of said structures A, A is a square vertical shaft 24 on each of which is a bevel wheel 25 also capable of a relative axial movement but incapable ot a rotary movement thereon. The lower end of: each i of said shafts is provided with a bevel wheel 26in mesh with a bevel wheel 27 on the axle of which is a spur wheel 28.

. The latter through an intermediate wheel 29, Figure 2, drives the spur wheel 30 which in turn meshes with the racks 31 laid parallel' and on the outside of two walls to be built. I

In mesh with the bevel wheels 25 are the bevel wheels 32 carried at the extremities of a horizontally extending square shaft 83 which is driven by gearing hereafter described. V r

wA mortar tank 34 is carried by the frame supporting the brick laying mechanism and which supplies mortar to the wall as the building proceeds. I V 1 The gearing'whereby the necessary move ment 1S imparted to spur wheel 8 to traverse thebrick laying. mechanism on the structure 13, and to shaft 88 whereby the machine as a avhole can be moved on the rails, and also the brick laying mechanism, will now be described. V I v A motor 35, see Figures 10 and 11, carried by a frame projecting from the carriage 6 drives through a train of gearing 86., 36 38 36, 36 and 36 a shaft 37 on which are two loose bevel wheels 38 and38 A slid'ng clutch 889., controlled by the hand lever 38, is adapted to engage with and drive "either of said bevel wheels. A third bevel wheel 38 on tlie'shatt 39 is in mesh with wheels 38 and 38, the three together forming a reversing gear for the shaft 39 on which is also keyed the spur wheel 39? which through the intermediate gear'wheel 39 see Figure ures 10 and 12.

13, drives the spur wheel '8 in meshwith the rack 5 and by which the brick laying mechanism is traversed on the structure B.

Also mounted-0n the shaft 37 is a bevel wheel 40 which through bevel wheel 40 drives the shaft 40 On the latter is a double clutch member 41, 41*, arranged toengage With either clutch members 42, 42 the bevel wheel 42 loose on'the shaft 40". Saiddouble clutch member is operated by a hand lever 41 through the links 41. j

Those clutch members are so arranged that eitherfot' them can be brought into engagement with the corresponding clutch member on the bevel wheelbut they are'set one at 180 in advance of the other.

Said bevel wheel 42 drivesthrough a bevel wheel 44 a vertical shaft 44 which at its lower end carries thespur Wheel 44 ,see Figures 1, 9,10 and 13. The latter is in mesh with the large tooth wheel 44 loose on a casting 44- from which the brick laying mechanism secured to s is suspended. Also in mesh with this wheel 7 is the pinion on the vertical spindle 45, see Figure 4, which, through the bevel gear in 45 45 drives the horizontal shaft 46 on which is keyed the cam 47 by which the brick laying mechanism is operated and which will be hereafterdescribed. 7

Also meshing with the spurwheel '36 is the spur wheel 48 on the shaft 48 on which are the loose spur wheels 49 and 50, see Fig- Spur wheel 49 gears directly with a spur wheel 49 on the transverse square shaft 33,

see also Figure 1, while spur wheel 50 is in mesh with the intermediate pinion 5O which in turn meshes with the spur wheel 5O on the said squaresha'ft. Both spur wheels 49 and 50 are capable of anaXial movement ontheir shaft. Also on the shaft 48 is a clutch -51 controlled by lever 51 and which can be operated to drive either of the spurwheels 49 or 50 according on the direction in which it is de'siredtorotate the square shaft 33. -'By such means the direction of travel of the machine on its rails can be reversed as desired or by bringing the clutch to a neutral position, the structure can be brought to rest.

The casting 44 see Figure 10, from which the brick laying mechanismis suspended is provided with a shoulder 44 which rests on the correspondingly shaped shoulder I44 of a ring 44 secured by lugs 44 to the carriage 6. Said casting 44 is provided with four notches 44 see also Figure 13 with one of which a latch 44 is normally in engagement and by which the casting 44 and bricklaying mechanism is prevented from rotating under the action of the tooth ring 44;

Said latch is carried at the end of a rod 100, the upper end of whichis'connecte d to a By pulling this latter thebell crank can be tomove vertically. 69 are guide rods se-' Lesa-27c operated to raise the latch 44 clear of the notch 44 thereby permitting the rotation of the casting 44 and brick layinginecli-anism with the tooth ring 44 through an angle of 90, the latch entering the nextnotch and lOCkiIlg the whole in position.

The framework 9 for holding the columns 7 plates 53 notched as indicated to accommodate the-bricks. The outer extremities of said plates are pivotally secured to the levers 54, 54 pivoted at 55, 55 respectively to themachine frame.

One of said levers 54 is connected to a helical spring 56, while the other end'thereof abuts against an arm 57 pivoted to the machine frame at 57. Also pivotally secured to the machine frame at 58 is a bell crank lever 58 connected by means of a link .59 to the arm 57 Pivoted to the machine frame at 60 is an arm 60 which carries a roller 61 and which is loaded by the two helical springs 62 maintained under tension. see Figures 3 and 4. To this arm is secured the two downwardly extending rods 63 which are connected to the rod 64 the lowerextremity of which is connected to an arm 65 'pivotally secured at 66 and connected by means of a short link 67 to a frame or plunger 68 provided with four projections 69 and-arranged cured to the plunger and which slide in holes in guide blocks 69 carried by the cross bars 69.

On one of the rods (33 is a stop 70 which coacts with one of the arms 58 of thebell crank lever 58. or frame of the brick laying mechanism is obtained through a pinion 70 on shaft 46, spur wheel 70, sprocket wheel '70", chain 70 and sprocket wheel 70, the latter being keyed brick retained thereby is about to be deposited on the wall. I The'mortar tank 34 is arranged to supply mortar to the upper side of'the course of bricks previously laid.

The operation of'th'e apparatus is as follows.

'Assume the brick laying apparatus to be travelling itSJIlCllCZLlBCl by the arrow Figure 1.

W hen laying this course of bricks the motor is transmitting motion to'the spur wheel .8

which, as it is in mesh with the rack 5,

The rotation of the drum' deposits the bricksas formerly.

causes thecarriage 6 and brick layingmechanism to travel along the structure B. Once every brick length traversed cam 47 permits the rods 63 to descend under the action of the springs 62 .which results in the frame or plunger 68 carrying the projections 69 descending rapidly and knocking out the lowest bricks carried by the frame and deposit same on the wall, the bars 72 simultaneously forc- 7 ing the arms holding such bricks slightly apart. Simultaneously the descending rods permit the arm 58 of the-bell crank lever to effect alike movement so that the arm 57 moves outwards and the lever 54, 54 turn about their pivots all under the action of the spring 56. This results in the notched arms co-acting sharply with and dislodging the lowest brick in each column, which bricks fall on the frame 11 and are received bythe upper'spring loaded arms which are opened to receive them by the action of th-e rollers 71.

As'the cam rotates further the frame-or plunger (38 is raised and'the projection 70 co -acts with the arm 58* to return same" to its upper position, the'notch'ed plates 53 under the action of the spring 56 being returned to the position shown in Figure 6 thereby allow- -ing the pair of bricks supported thereby to fall on to the'plates52. In like manner, as the carriage 6 and brick laying device'moves along the wall, a pair of bricks is intermittently fed to the frame or drum and a'pair of bricks simultaneously deposited on the wall." g 6 It will be understood that the spur wheel 8 must move the carriage 6 a distance equal to, one brick length plus the thickness of a mortar joint while the cams 47 makes exactly one revolution. 'lVhen the end of the wall is reached clutch 38 is operated to bring the machineto rest and by meansof the links 102 and 103 the latch 44 is raised clear of the U notch with which it is in engagement.

Here it would be explained that the resistance offered to therotation'of-the camshaft 46' is greater than that offered to the rotation lie of the brick laying mechanism bodily so that w the casting 44 then rotates withthe tooth ring 44 and carries'pinion 45 and brick laying mechanism with same; a pawl engaging rotating in the reverse direction.

When the brick laying mechanism has been a ratchet wheel 103 'prevents the cam shaft turned through an angle of 90 the latch en-,

gageswith the next notch thereby preventing further rotation. Clutch 51 is then oper ated to drive the square transverse shaft 33.

This shaft drives through the bevel wheels machine as a unit along the rails. During this movement @the brick laying mechanism 32, 25, 2 6, 27 and spur wheels 28 and29 the spur wheels 50, which being in engagement with the racks 31 on the rails 1 traverse the outof gear to bring the whole structure to rest, the laying mechanism again moving.

the transverse square shaft and thereby move the apparatus bodily along the-rails, the brick a ine a J ara us de aositin a courseof bricks 1 a t a during its travel. At the end of this wall it is necessary to raise the transverse structure .a distance equal to the height of a brick plus the thickness of alayer of mortar. This is accomplished by an attendant mounting the platform 22 and operating the winding. gear 21 whereby the ropes 15 are wound on the drum 16 and the wiole transverse structure raised to the requiredextent.

The brick laying apparatus is rotated through an angle of 90 but before proceeding to lay the next course it is necessary that the brick laying apparatus be moved dis tance equal to half a brick length before commencing to 'deposit'the second course. This is effected by withdrawing the double clutch member 41, 41 to aneutral position and, as thebrick laying apparatus traverses the member 13, slipping it into the clutch member 4-2 or 42 which is half a revolution behind the member previously in engagement. therewith. As shafts 39 and 40? rotate one revolution per brick length, this results in the second course of bricks being laid in proper stag- .gcred relationship with the course immediately below.

In like manner the second and other courses are laid. a

It will be noted that the brick laying mechanism always acts in timedrelationship with the gear for traversin the brick laying mechanism and for traversing the apparatus bodily on its rails, the. clutches" being capable of engagement only at one point perrevolution of their corresponding clutch members; i

The bricksare fed to the receptacle'9 by an attendant whostands on a platform 99, Figure '12. In order to accelerate the process of building means are provided whereby the attendant is automatically supplied with bricks, as indicated diagrammatically, Figure l.

V This may beaccomplished by suspending a V cage 99 at the, outer side of each of the upright structures A, A the ropes supporting the cage passing over pulleys at the upper ends of said structures, pulleys carried by the structures B and then connected to carriage 6. i The arrangement is such that as the said carriage with brick laying mechanism traverses structure B one of said cages is lowered to filled with bricks While the other one is raised so that when the attendantreachesthe end of his travel he is provided with'a cage of bricks to feed to tl'ie'bricklaying device.

As thecross member is raised the ropes automatically become shortened andthey are attached on roller having driving gear by which they are rotated to allow of the slack being from the bands and deposits same on thewall.

Secured to projecting brackets 82 onthe frame is a cross shaft 83 on which are secured an arm 84 and two arms 85 one ateach side of the m chine. Arm 81 carries a roller 84 at its lower end, while the extremity of each 7 I of the arms 85 is connected bv means of a rod 86 to a lever 87 pivoted at 88 and carrying a roller and, bevelling or skimming bar 89. A'

helical spring 90 is connectedto the levers 87 and frame.

The action of such device is as follows: After each brick has beenlaid and the machine has traversed one third the length of a brick the cam through the aforesaid mechanism permits the scraper to be moved to-V wards the last laidbrick under the action of the spring 90, some mortar being scraped up in its travel and deposited against the exposed end of the brick. Further said bar pushes the bricks up against the adjacent brick thereby consolidating. the wall being built.

As shown in Figures 8 and 8 guiding arms' 91 are carried by the brick laying "apparatus g and which serve to ensure that each brick is brought into alignment; as the courses are laid. To permit the brick laying apparatus to be moved through an angle of 90 as aforesaid said guide arms must be raised clear of the wall. This is accomplished'by mounting the arms on the pivoted parallel arms 92 and connecting same to a vertical rod 93 by raising which the guide arms are likewise raised so as to permit the partial rotation of the brick V laying device. It is desirable that the mortar in the tank be kept in a state of agitation.

In the arrangement shown this is effected by means of a stirring blade 94 (see Fig 5) carried by arms 94 on a crossbar keyed to a shaft 94" on which is secured an arm 95 (see also Fig. 3)- the latter being connected by means of a rod. 96 with an eccentric 97 onthe shaft of roller 74:. V

By such means the mortar is kept in a'contmual state of agitationwhen the apparatus is in operation.

g The structure by which the brick layingapparatus is supported may be modified. For

example at each side of the 'buildingt o be built two vertical structures may be erected each provided with horizontally extending structures arran ed parallel to each other and to two of the four walls to be built. A cross member extends between and joins the horizont ally extending structures and is arranged to travel along same. The brick laying mechanism is mounted to travel along said cros's member. v r 1 f In operation the brick laying mechanism first travels along the cross meniberaiid lays a course of bricks on one of-the walls the v cross member is then traversedv along'the said horizontally eutending structures, the brick laying mechanism depositing a course-oi bricks on one ojt'the sidewalls.
