In forming a brick laying machine embo'dying the invention the same maybe supported by special supports invario'us'way's, as desired. In Fig. 1 a supporting bar 1 15pm vided' which is adapted to be secured to a-' v building, or if preferred, may be supported uprights wherethere is no ironfr'amewo'r of a building available. Pu'lleys'j2 and 3 are carried by the bar 1, and over these pulleys cables fi and 5' are passed, s'aid cables being secured at their respective'ends tothe chan-v nel iron 6. The free ends of the cables may be tied to'the channel irons 6 or to some other article, whereby the device will be supported-j at the desired height. After the device has" eration and maybe operated by two inex f perience'd men,or at least, by two men inex periencecl in briel'z-laying", though experr ienc'e'd' help may be used, if desired, orma' i be used supervising several of the m'aJ-Q chines. As hereinafter fully described, there. are provided a number of box s to bel'o'c'atedi on the ground or a suitable flooring, and one of the workmen functions to fillthese boxes,"
functions. After the machine has started to operate the same lays batches of bricks from the right end of the wall to the left, or the reverse according to the way the device is set, and after a given series of batches of bricks have been laid the device is elevated and a new series of batches laid. This is carried out until the full height of the wall has been reached and then the device is elevated to a new wall or shifted to a new wall in any desired manner.
As shown in Figs. 1 and 6, the channel bar 6 movably supports a scaffold 7, and the scaffold 7 carries what may be termed a brickraising frame 8 shown in detailin Fig. 7. Also,scaifold'7 carries a sliding frame or gear casing 9 (Figs. 1 and 6), which in turn carries the brackets 141, shaft 132 and associated parts hereinafter fully described. The frame 8, as shown in Figure 1, is of appreciably less width than scaffold 7 and functions to raise andlower the series of elevating rods 9 (Figure 3), said rods acting to intermittently elevate the various bricks 10 in the box 11. The parts are so proportioned, as hereinafter fully described, whereb each movement of the rods 9 will raise tie bricks 10 the height of one brick, so that the various grippers 12 may function to grip the bricks and move them to a position on top of wall 13.
The box 11 is a rectangular box formed of wood, metal or other material and carries suitable rollers 14: which rest on the runways 15 and 16. The box 11 is providedwith a number of apertures 17 through which the rods 9extend, said rods pressing against a plate 18, and on this plate is arranged a special pattern plate 19 adapted to receive the lowermost layer of bricks 10. After the bricks have been laid on the pattern plate 19 a second pattern plate 20 is mounted on top ofthe first layer of bricks and a second layer of bricks mounted on the pattern plate 20. This idea is carried out until there are provided four layers of bricks, though, if desired,
a greater or lesser number of layers may be provided for. The various pattern plates are provided with upstanding flanges, whereby an inexperienced person can lay the bricks properly, the arrangement being identical with the arrangement in wall 13. The workman on the platform or ground arranges the bricks in a box 11 on the ground, and when the workman on the apparatus needs a new box the filled box will be elevated to the workman on the apparatus and the empty box lowered.
In order that a convenient means may be had for elevating the filled box and lowering the empty box, a hoisting drum 21 of any de sired kind is provided carried by shaft 22 mounted in suitable bearing boxes 23 on the scaffold 7. A control or driving structure 24 is connected to shaft 22 for rotating drum 21. The device 24 may be an ordinary sheave operated by hand through a suitable rope, or may be an electric motor with the switch controlled by the rod 25. lVhen the box 11 is first placed on the runways 15 and 16 it is rolled to the left, as shown in Figure 1, until it strikes the stop 26. After the bricks have been removed from the box it is moved back manually to a position over the doors 27, which doors are shown particularly in Figure 2. These doors are hinged at 28 and 29,
Y and by reason of the brackets 30 and 31 will move downwardly to a horizontal position but may be moved manually to a vertical position. These doors and a similar arrangement of doors 32 (Figs. 2 and 6) act as platforms for the workman on the apparatus, whereby he may be properly supported as he causes the parts to function properly. When the box 11 becomes empty it is moved to a position over the doors 27 and is then connected to the chain or cable 33. The box is then elevated until the door-s 27 may be opened, after which it is lowered and a new, filled box secured to the cable 33. Drum 21 then caused to function and the new, filled box is raised until the doors 27 may be closed. The filled box is then lowered to a position over the doors 27 and finally moved to a position against stop 26. The new box is then in position for the remaining part of the apparatus to function and lay the bricks in the new box. When the new box becomes empty it is returned to the ground or lower platform and anew one secured, as just described.
In order to remove the bricks from the box after the box has reached the position shown in Figure 1, the various grippers 12 are caused to function, whereby the top layer of bricks is grasped, raised and transported to a position above wall 13. The brick-s are then lowered and released, after which the grippers 12 move back to their former position. lVhil'e this is being done the workman manually removes the top pattern plate and the frame 8 will have functioned, as hereinafter fully described, for raising the next layer of bricks up to a position where they may be engaged by the grippers 12. The grippers 12. are arranged in three rows, as shown in Figures 321ml 12, whereby they may properly engage the ends or sides of the respective bricks. Each of these grippers is mounted between suitable plates 34 and 35 which are formed integral with or rigidly secured to a top plate 36. Between each pair of plates 34: and 35 is positioned a bar 37 having a notch 38 for each of the grippers 12. The grippers 12 are formed, as shown particular in Figure 13. In this Figure it will be seen that a bell, crank lever structure is pivotally mounted at 40 on the plate 34. The link 41 is pivotally connected to the arm 42 of lever 39 and to the outer end of this link is pivotally connected the arm 43 of the gripping jaw 44. The arm of jaw 46 is pivotally connected at 47 to link .42? which is pivoted to arm 42 and link 41 at 41 and is, also pivotally connected to jaw 44 by the pin Y 48 attached to plate 34 (Fig. 11). A spring 49 connects the arms 43 and 45'and acts to move these arms for opening the jaws 44 and 46, whereby these jaws will grip adjacent brick-s. Each of the jaws is provided with a rubber orother cushion 50 so as to resiliently grip the bricks and also to present a better gripping surface to the bricks. The outer or free end of the bell crank lever 39extends into notch 38 so that when bar'37 is pulled I5 in one. direction the jaws 44 and 46 will be closed. WVhen the bar 37 is released the springs 49 on each of the grippers 12 will have a tendency to move the jaws to an open' position so as to grip the bricks if the parts 7 are correctly positioned. The respective bars 37 are connected together by transverse bars 51 and 52, as shown inFig. 2, so that all of these bars act together- Bar 51 is provided with a stop or projection 53 which may be operated manually when the grippers are above wall 13, or may be caused to strike a suitable stop so as to operate the various bars 37 and thereby release the bricks. The bricks as soon as released drop a short distance and automatically, take their place in correct order on top of wall 13, DIOLELI having previously been applied as hereinafter'described. In order that the bricks may be properly centered, a guiding structure is provided which consists of a pair of U-shaped frames 55, and on these frames are arranged two pairs'of rollers 56 and 57. Each pair of rollers supports a belt 58, said belt snugly fitting against the sides of wall 13. Rollers 56 extend above wall 13 normally and thereby the belts 58 with the frames properly guide theifallen bricks to a correct position on 'thewall, the bricks having been previously arranged in the fproper order, as set i forth in the description of the box 11. After a layer of bricks has been deposited on the Wall 13,.the frames 55 and associated. parts are moved upwardly thedistance of a thickness of one layer of bricks plusthethickness of the mortar, whereby it actsi'as a guide for the next layer of bricks. In order to swing the grippers back and forth, namely, from the position shown in Fig. 3 to the dotted position in Fig. 11, and then back again,
be secured. Thesegears also are associated with certain other gears hereinafter fully described, whereby the crank 64 is swung back and forth. This crank is journaled in a suitable bracket 65 and the free end extends through the slot 66 (Fig. 2) in the plate 36. As shownv in Fig. .2, whenthefcrank 64 is swung a certain distance the plate 36, grippers 12 and associatedpartsare moved over to a position above the wall 13. Plate 36.
and associated parts are supported by suitable trolley wheels 67 positioned to .run on the lower bars of the frame 59. As the crank 64 moves'from the full-line position shown in Fig- 2 to the dotted line position the wheels 64 will roll along and move the parts to a, position directly over the wall 13. The wheels 67 and the brackets to which they are connected pass into suitable recessesor passageways 68 and 69 (Fi 4), whereby they will not interfere with the mortar box 70.
As the plate 36 and associated parts move back to the position shownin Fig. 3 the shoulder 71 is adapted to strike the projection 7 2 (Fig. 5) and pull the rod 7 3. This rod is connected to the various gates 74 and 75 by levers 76 and 77 A return rod 7 3' is connected to the arms 77 and to the rods 73, so that both of the gates 7 4' and 75 will be opened or closed according to the direction of rod 73. When the shoulder 71 strikes the projection 72 the gates 74 and 75 will be 7 opened and any mortar inthe chamber or space 78 will drop down immediately onto the wall 13 and will cover the bricks thereon to a greateror lesser extent. This mortar is preferably sufiiciently fluid to fiow .into the spaces between the respective bricks and the remaining mortar presents a covering for all of the bricks.
a new supply of mortar is deposited on the new layer of bricks. After the gates 74 and 7 5 have been opened, as described, the parts are caused to function .so that a new layer of bricks will be'brought over and depositedon. thewall 13. sociated'parts move over toward a position above wall 13 the projection 79 (Fig. 2)
strikes the lever 80 (Fig. 3). Upon the actuation of lever 80 a slide 81 is moved so that I the openings therein will register with the openings 82 inthe bottom of the hopper 7O whereupon mortar will flow down. into the chamber 78 readily to be discharged at a later time. As soon as the lever 80 is released by the movement of the projection 79 and associated parts back to the position shown in Figure 3, a suitable spring 83 (Fig. 4')- will function to close the slide 81. The chambers 7 8 will then be loaded so that as soon as the shoulder 71'reaches its full return.
position and strikes the stop 72 (Fig. 5) doors 7 4'and 75 will be opened and the mortar will be allowedto drop on thenewly laid Onto this mortar the next. layer of bricks is laid or dropped'and then.
As the plate 36 and. as
bricks. This action is repeated as often as the parts function and as these parts move the frame 55 and associated parts intermittently move upwardly. As shown in Fig. 4, the slide 81 is divided into three parts, each part being connected with the lever through a suitable rock shaft 84 and through arms 85. In order to cause the parts to function as just described, namely, to cause the crank 64 to swing from one position to the other and thereby cause certain other movements, the end of crank 64 which extends through the bracket 65 is rigidly secured to a beveled gear 86 (Figs. 3 and 11). This gear continually meshes with beveled gear 87 rigidly secured to shaft 88. An arm 89 (Fig. 11) is rigidly secured to shaft 88, and to this arm is pivotally connected link 90 which in turn is pivotally connected at 91 to the arm 92 rigidly connected with the shaft 93. A pinion 94 is also rigidly secured to shaft 93, and this pinion is positioned so that when the teeth of the mutilated gear 95 passes, said teeth will mesh and rotate the pinion 94 for approximately a half revolution, thus pulling the parts from the position shown in Fig. 11 to the dotted position and thereby swinging crank 64 from the full line position shown in Fig. 2 to the dotted line position shown in Fig. 2. The gear wheel 95 moves out of mesh with pinion 94 after it has swung crank 64 to its extreme posi tion, as shown in dotted lines in Fig. 2. The gear wheel 95 continues its movement and onthe next'revolution meshes with pinion 94 and gives the same another half revolution, whereupon crank 64 is moved back to the full-line position shown in Fig. 2.
The shaft 88 is divided, as shown in Fig. 8, and the respective arms 89 connect the parts through the pinion 96, thus permitting the shaft to rotate properly throughout its length and at the same time move the link 90. The
shaft. 88 extends through suitable bearings 97 and 98 and also through a sleeve 99, said sleeve having a pair of upright or outstanding arms 100 pivotally connected with the link 101 which in turn is pivotally connected to the arms 102, and said arms in turn are rigidly secured to the shaft 93, which shaft.
is divided into several parts, as shown in Fig. 8. The sleeve 99 is adapted to have a back and forth rocking movement, while shaft 93 rotates through the action of mutilated gear 95 acting on the pinion 94. The rotation of the shaft 93 causes an intermittent rotation of the gear wheel 103. These parts are arranged so that not only will the parts shown Fig. 11 function properly, but the raising mechanism shown particularly in Figs. 3 and 9 will function properly to raise the scaffold 7 and frame 8. To cause an upward movement of the frame 59, the gear wheelsi62 and 63 continually mesh with the racks or uprights 60. Gear wheel 63 is rigidly secured to the shaft 93, and as said shaft intermittently rotates motion will be transmitted to gear wheel 63 and through gear wheel 63 to gear wheel 62, so that the racks 60 will be raised and all parts connected therewith. The parts are so proportioned that upon the half revolution of gear wheels 62 and 63 frame 59 and associated parts will be raised the distance of the thickness of one brick plus the thickness of one layer of mortar.
To secure the operation or driving action of the various gear wheels above described, a casing or frame 104 is connected with frame 7and carries the journal members 97 and 98 and certain other parts, including bar 105 on which is mounted a prime mover, as for instance, an electric motor 106. This electric motor is provided with a worm 107 which continually meshes with worm gear 108, which worm gear in turn is rigidly secured to shaft 109. To this shaft is secured the mutilated gear 95 used to operate pinion 94, and also to this shaft is rigidly secured the mutilated gear 110. Mutilated gear 110 intermittently engages the large pinion 103 which is secured to shaft 93. From Fig. 8 it will be noted that shaft 93 is separate from shaft 93 but abuts the same and the divided shaft 93' abuts but is separate from the shaft 93". As indicated in Fig. 8, there are four uprights 60 and two of the gear wheels 63 mesh with two of these uprights, and two of the idlers 62 mesh with the other two uprights, so that when the various gear wheels 62 and 63 function the uprights and also the frame 59 and associated parts will be elevated. In order to elevate the frame 8 and associated parts independently there is provided a large gear wheel 111, said gear wheel being rigidly secured to shaft 88. Connected to this shaft is a pinion 112 meshing with'pinion 113, pinion 112 also meshing with the rack 114, while pinion 113 meshes with rack 115. A mutilated gear 116 intermittently meshes with the gear 111, so that this gear and parts associated therewith will be caused to function at the proper time to raise the frame 8, rods 9 and other parts, as heretofore set forth.
In order that the bricks may be properly laid in batches, the device after each batch has been laid, must be moved over a certain distance to the right or left according to which way the bricks are being laid. In order to secure this result automatically, the channel iron 6 on the lower surface is provided with a rack 117 meshing with idlers 118 and 119 and with a driving'gear 120. This driving gear is rigidly secured to the shaft 121, and said shaft carries a beveled gear 122 at the outer end. Beveled gear 122 continually meshes with beveled gear 123 rigidly secured to shaft 124. Shaft 124 carries a beveled gear 125 meshing with beveled gear 126 which i'srigidly secured to the shaft 88. As
- shown in Fig. 6, pinion 125 is splined onto the 89, link and associated parts. From Fig.
8 it will be noted that the arms 89 are rigidly secured to a sleeve 89 and to this sleeve the beveled gear 87 is rigidly secured. Shaft 88 extends loosely through sleeve 89" so that the beveled gear 126, as well as the beveledgear 127 will operate intermittently as the large gear 111 is moved by the mutilated gear 116 (Fig.7) actuated through shaft 109. In this way the power from mutilated gear 116 will actuate shaft 88 for raising the casing 10 1 and associated parts and also for moving the entire scaffold 7 laterally along the supporting channel bar 6. From Figs. 1, 6, 8 and 10 it will be seen that the'beveled gear 127 meshes with the beveled gear 108 splined on the rod 129, which rod has a beveled gear 130 rigidly secured to the upper end. Thebeveled gear 131 continually meshes with gear 130, said beveled gear 1'31 being rigidly secured to the shaft 132 carrying gear wheels 13 1, which gear Wheels continually mesh with racks 1'35 formed on one edge of the respective rack bars 136. The respective rack bars 136 are riveted orotherwiserigidly secured to the upper part of the scaffold 7 and depend there: from so as to continually permit a proper meshing of the gear Wheels 134 with racks 135. A series of teeth .137 are formed on the opposite side of the bar 136 to the rack 135, said teeth coacting with an escapement pawl 138. This pawl is pivotally mounted at 139 on the sliding frame 9 and is actuated manually by a rod 1&0. It will be noted that the shaft 132 is mounted on suitable brackets 141 rigidly secured to frame 9, which frame in turn is riveted or otherwise rigidly secured to the channel support 6. In this way whenever shaft 1321s rotated scaffold 7 and frame or bars 7 will be raised or lowered according to the direction of rotation of the shaft. During the ordinary operation of the device the shaft is rotated in such a direction as to raise the scaffold 7 a distance equal to the thickness of'one layer of brick plusfone layer of-mortar. While this is taking place the frame 8 is being raised within the scaffold a distance equal to the thickness of one Ibri'ck plus the thickness of one layer of mortar. As
layers of bric'k and the-mortar associated therewith. When it is desired to lower the scaffold in res ect to the bar 6 rod140 is scaffold is lowered without being dropped. It will 'be noted that this escapement pawl permits this loweringaction, as just described,
While also permitting the parts to be raised by the gear wheels134 and associated parts.
As' the scaffold moves upduring the laying ofthebricks the guiding loops 142' and 143 (Fig. 3 slide along therespect ive bars 141,
said 'bars' being riveted, welded or otherwise 7 secured'at their upper ends to the channel bar 6. The scaffold 7 is provided with a transverse rail 145 (Fig; 3) on which the rollers v146;carried by theloops143rest, whereby the frames 55 and associated 'parts'a're allowed an up and down movement, the'latter move- '85 ment being independent ofthe scafio1d'7','except that the scaffold 7 acting through har 14:5 will raise the frames 55 and associated parts each time the scaffold is missed by the gear Wheels 134: and associated parts.
In operation the cables =4 and 5 are connected to the meta-lwork of a bui lding or some other support, so that the bar Swill be suspended at-a desired position adjace nt the w-all. Preferably there are several boxes 11 correctly arrange the bricks :the same as they will appear in wall 3. After this has been done plate20 is applied and a second layer of bricks is placed in the box. This method is carried out until the box is filled which,'in the present instance, will hold five layers of brick. Byreason of the beads of the plates in the 'box an inexperienced workman will correctly arrange the bricks, and'then at the proper timethe box is elevated by the chains 33, drum 21 and associated parts. After being properly elevated it is moved over manually tethe position shown in Figs. 1 and 3. At a convenient time a similar box or other container is engaged with the chains 33 and elevated through the action of dmm 21. The mortar is manually dumped into the 'hopper' 70 and the empty mortar hex is again lowered. This leaves the platfor'mBZ, as well as platform 37, empty so that the workman may stand thereon. After the 'box has been placed in position, as shown in'Fig.
1, and the proper'supply of mortar provided power is turned on to'the mo t/W106 and the "I25 grippers 12 will begin to These grippers Will grip'the top layer of brick and then the frame 59 and associated parts willbe raised to a certain extent, after the crank 64 will move the grippers and bricks over'the wall 13. The leis-irks are dropped 71 130 onto the wall by the releasing of the grippers 12 and then the crank 64 moves again to shift the grippers back to a position over the box 11, after which the bricks in box 11 are raised by rods 9 and associated parts. As soon as the grippers 12 move back to substantially the position shown in Fig. 3 the shoulders 71 will strike abutment 72 (Fig. and will operate the various parts disclosed in Fig. 5 and at the left in Fig. 3 for opening the doors 74 and 75, thus permitting the mortar in chamber 78 :to drop down on top of the new layer of bricks. The mortar is comparatively liquid so that it will flow over the bricks and into the space therebetween but will be restricted to the newly laid bricks by the frame and bolts 58. At the next operation the projec- ,tion 79 will strike lever 80 for shifting the slide 81, whereupon the doors 74 and 75 will be closed and a new supply of mortar will be allowed to flow into the chamber 78 ready for "the next layerof bricks. This action is carried out until the box 11 has been emptied and then. the empty box is lowered in any desired way, as for instance, by being connected with the chain 33 and lowered downwardly after thedoors 27 have been manually elevated. A new box 11 is then elevated and moved over laterally to the position in Fig. 1, whereupon the device is ready for a second operation. After each operation ofthe grippers 12, or rather, after these grippers move back to a I position over the wall 11 to substantially the position shown in Fig. 3, scaffold 7 will be elevated and also the frame 8. This is accomplished through the action of the gear wheels 134, shaft 132 and associated parts, as well as through the action of gear wheels 112 and 133 shown in detail in Fig. 7. After each batch of bricks has been laid on the wall the machine moves laterally along'the wall, for instance, toward the right as indicated by the dotted layer of bricks in Fig. 14. It will be understood, of course, that the machine could move in. the opposite direction. This move- Inent is, produced by the wheel 120 meshing with the rack 117. The machine could be used to lay the first layer of brick in the wall, but ordinarily this is done by hand and one jcorner isbuilt up somewhat, so that the ma chine will lay the successive bricks from one .corner to the op osite corner. At least one experienced wor man should be used with the machine so that at certain parts of the wall where the machine cannot properly function the experienced workman can manu'ally'laythe brickin the usual manner so as ,-to connect up parts of the wall or take care of other contingencies. i
