My invention'yhas forl its obiect to provide a derrick particularly adapted for. the

' construction :of walls formed oft bonded slabs. The invention has possibly its great.-

est advantage in the construction of J walls blocks that are placed ontheir-endsand have edge grOOve'sand ridges -thatwinterfit, and

wherein the wallsareexte riorly bonded by tension members. that; produce inward pressure upon the-wall. The invention particu- V larly h'asforits':objectto provide a'derrick whichfwi'll coact with/ exterior bands to cause the 'blocksof alternate courses to flare wheres byslabsfmay be easily placed in courses contiguous to those with, which" the blocks are interbondedin the formation of p the. con

structions The invention also provides a means whereb the outward pressure that producesfthe ared condition maybe easily removed while at-the same timexthe. workmen are supported so that they maytighten the bands to remove the fiared condition and maintain the cylindricityv of the structure as the work p'rogressesm The invention mayfbe contained in derricks of differentf lforrns and for producing constructions that vary in shape and: to illusis shown in' the accompanying :Fig. 1 is aside'v'iew of a constructionthat is: represented as being builtandipartof the structure'beingshown broken away to illustrate parts of the derrick and its operation.

In'the particular form of the Invention i that has been selected for the purposes illustrating its application, a cylindrical structure is shown in the process of beingformed. The bui-ldingmay be for the purpose of storing or containing coal, that is, it' may be a v coal bunkeror it maybea silo oranysimi- I *la'r structure."Thestructurejis formed of slabs l' having a, groove onto n e. of its.

edges and a-groove3'on one of its end edges,;

the latteris preferablylon the lower end for the purpose of shedding water. Each? block is also provided with a rib 4; ononeof-jits side edgesand a rib 5 located 011 its top ed e that fit the corresponding groovespf the; 113-- joining blocks.

alternately with full length slabs inistar tingethees'tructure; The structure is bonded byl nean's of bands or rods 7 that are located substantially at the joints of; alternate courses. -=Theends of the bands'or rods 7 are tied together by. suitable members that. draw the ends together and thus tightly clamp the blocks. 'As illustrative of such a means, there isishown in the drawings a block 8 that is clampedbetween the nuts 9 that are'thread ed ontotheendsof each rod 7,1, g In order to support the workmen so that they canreadily place the. blocks in position,

and thus rapidly construct ;the;building, a

derrick lOfiis supported on the up er ed es ofcertain of the blocks; p be bers or frames 11 that havehooks 12 that fit over the upper edges of certain of the blocks. A, plurality of links 13 are connected to the frames 11 bymeans of the ears 14:1 that'are located at points that are alitt-le less'thanthelength?of the blocks below the hooks 12.- This places the pivot pointof the connection between eaclrlink13 a little above thelower end of theblock on which its asso- ;ciated=frame-1l issupported.

The links 13 are also pivotally connected to a ring 15 from which the links113 radiate.

The slabs ;1 are-placed on" 'llhBlI endsand halI" length slabs are placed The derrick 10 is provided with a plurality of'hookedjmem- The ring, 15 is provided with lugs or ears 16 and bolts 17 extend through irons 18. The ears 16 pivotally connect the links 13 to the ring 15. The links 13 are somewhat longer than the distance between the center ofthe .buildingand the pivot pins in ears 1 L so that vwhen the ring 115 is raised to near its highest possible point the links 13 slope up ward to the frames or members 11' at ,a slight angle.

The ring 15 is connected to a 'U-member' QO-tha't forms a bail forsupporting the'ring 15 1A tripod 19 has itslower ends or feet supportedon three of the, links 13 atpoints I ber 20. A rope or that are near to the frames or members 11. The lower ends of the parts of the tripod 19 are pivotally connected to the cars 22 by means of the bolts 23. The upper ends of two of the members of the tripod 19 are provided with bent irons 24; and a bolt 25 extends through the third member of the tripod 19 to pivotally connect the tripod members toget abl connected to the upper end of the tripod an a pulley 27 is connected .to :hhfi Unnamcable 28 extends over the pulleys 26 and 2-7 which may be operated to raise or lower the rin 15 and the midi of the rope 28 may be suited) y fastened in order tosecure the rlng in the position in-Which it is thus placed. 1

When the ring 15 is drawn upward the links 13, acting as members of a toggle joint, are pressed outward. Since the hooked members llare pivot-ally connected to the ends of the links 13 at a point slightly above the lower ends of the blocks on which they are sup orted, the thrust that is thus pro duced ares the blocks outward. Because of therib and groove interconnection between the blocks, the blocks, adjoining those on which the frames 11 are so ported,will likewise be flared outward. Tlns increases the spaces between the side edges of the uppermost row of blocks and hence new bloc s may be readily inserted between the higher alternate courses. 1 a a r The flaring of the blocks is limited by a band or rod that is placed along-a mid-point of blocks ofalternate courses, among which are the blocks on which the hooked members or frames 11 are supported. This uppermost band is thus placed along the upper end edges of the blocks of alternate courses and by means of the nuts 9 it is adjusted to permit the desired play of the uppermost blocks to produce the required spaces between them an so as topermit the placement of the contiguous row of blocks in alternate courses.

When the new row of blocks hasbeen laced in sition, the derrick is loosened by oweringt e ring 15 which operates to reduce the thrust of the links 13 a ainst the members 11. The uppermost r0 or band 7 may thus be tightened so as to draw the blocks into position and tightly bind them by reason of the grooves and ridges and by the band 7 itself. jThe hooked members or frames 11 are then placed so their hooks en gage the uppermost edges of blocks inicourses contiguous to those thatin the preceding operation supported the frames and' at the the same time a succeeding band 7 ma be placed along the edges of the blocks w new the hooks were previously located, the ends of the band being somewhat loosely connected so that when the ring 15 is drawn'upwards by the operation of the cable 28 the uppermost rows of blocks will be flared and secured to the lower ends er. A pulley 126 is also suitsporting the means connected to the frame for raising spaced from each other to puma, M cad placement of another row of bloc li s ad ing; force. The operations described are repeated as the structure of the building progresses.

The workmen are supported on a platform .30 that is supported by rods 31 that are members or 'frames 11 and to bars 32 that protrude from the frames 11 and form a triangle that rigidly holds the rods 31 and the :bars 32 in position. If desiredthe rods 31 may be extended upward and a protec tive railing or cable 33 may be locatedflon or sup orted by the upper-wands of the rods a P anks 34 are located on the bars 132 onwhich the workmen may stand while plac mg 11 are .to be placed on the hiher courses, the workmen will sit on the en s of the blocks and pick up the frames .11 and place them in position.

The cabled? may be passed overa pulley block 38 that may be supported on the ends of rods 39 and 41.0, one of which may be connected to one of the uppermost blocks and the other con tongs 35 may be connected to a nectedto the upper end of the tripod as \indieated in Fig. 1. As the blocks are raised they are taken by the workmen and placed in position. i
