vBe it knownlthat I, Denim,v VKlU'sTrN Srmnnnn, a citizen. ofthe :United States,

and residentof Granton, in th'ellcounty of Clark and Stateo'f VVisconsin, have lina vented a certain newand useful Removable Mold for Concrete Walls, yofwhich the fol lowing'is a Specification. Y

This inventlon relates to improvements in molds for forming concrete ,walls for buildings, more speciically,to that class of Y moldseprwhich are employed .in building double walls with 'ani air space betweenA them ,j and in that class of forms or molds in which the mold members are moved upwardly as the walls are constructed. In

plates or boards spaced apart a distance equal tothe thickness'of the wall members, and of a depth from oneto two feet; These members are firstplaced adjacent to the ground surfaceand then filled with concrete.` After` the concretehas set, .the moldy members are. moved .upwardly withtheirflower edges adjacent Lto the top edge of the wall, thus providing space between lthe members 5 which may again be filled with concrete.

The plates are usuallyheld imposition relative toeach other-by means of blocks placed between thermembers and wires to tie them together., Thisisga very awkward and expensive Way of mounting the4 plates,- and it is therefore the objectvof myl invention tclprovide new and Aimproved meansy fori mounting the plates soy they `maybe easily *andv quicklymoved to their new position),vv f c I 'f A rstill further Objectis to provide in a movable mold for forming double concrete walls havingvparallel and horizontallyparranged mold members,improv ed means for mounting the mold members sothey may be easilyV and quickly disengagedfrom ythe walls, and also provide means whereby the said'parallel mold members may be 'adjustably mounted relative to each other.

These and otherobjects will be lapparent to those skilled in the art. ,v y c My invention consists in the construction, arrangement and combination of the various parts of the device, whereby .thefrfobjects contemplated arev attained, as hereinafter more fullyset forth, pointed out in my claims, andV illustrated inthe accompanying drawings, in which: Y

y Figure 1 is a sideelevation of asegment L of myl improved mold `construction showing the manner in whichit is applied to a wall.

c Fioure 2 is a transverse Sectionalview of the same taken on` the linel 2-2 of FigurelL, Y, c V Figure -is a' plan view of one of the mold supporting frames.

Figure 4. is a detail view form of one of the frame members. Figure 5 is a detail plan view showing the manner in which one of the mold members is provided with means for forming the upper roof portion of the end walls of a building.V

of a v*modified Y l have used thelreference numeral 10 to `Y indicate the walls of a building whichA are mounted parallel to` eachother and spaced apart a slight distance's'o `aste provideja'n air space between them.

The numeral 11V indicates mold platesr which are placed adjacent to the outer edges of each of thewall'members 10 with their lower edgesadjacent to the upper edgel of thefwall membersY 10`so` that the said plates maybe filled 'between' them :for the purpose f cf'increasing the height of Vsaid members. ,"Fo'r securing these plates 11 inposition, l'have'provided a series of brackets which arespaced apart atequalintervals Aalongf thel entire length of the wall in whichfpthe' plates extend. T 'Thisf'rame comprises series of vertical members 12 placed adjacent to"y the outer face of each of the plates 11,;the` ha said.` platesV being secured iny position by means of lugs 13 which extend into dove f tailed groovesfll Ton the inner edge of k'each vof the' members 12, asclearly shownin Figure 2. l w n' These lugs 13 may be of any desired length, preferably'three 4or four times the width of the member12 so that vthe said members 12 may be attached or detached by simply moving them longitudinally with. thefmembers 13. n

`The members 12 ,extendy above the upper edgesof the plate a considerable distance. Each of the inner me1nbers`12is slightlyy horizontally 'and transversely arranged glink 15 which is placed a slight ydistance above the rf per edges of the plates 11. rlhe outer Vspaced apart and pivotedly connected to a members are each pivotedly connected'to the same bar'15 by means of bolts 16 ina-ny one Y .of a seriesof openings 17,sa1d openings being arranged sov that Vthe said out-ery members 12 Y 18 by means of a may be adjusted. toward or from the inner members.

The upper end of each of the members 12 is pivoledly connected to one end of a lever bolt 19, said bolt being designed to be mounted in any one of a series of openings 2O in the said lever, the said levers 18 being mounted in a substantially horizontal position when the device is applied to a wall, one of the ,said levers being` arranged to rest adjacent to one side of the members 12, while the other lever is designed to rest adjacent to the opposite side of said members and the said levers eXtended in opposite directions. The outer endy of each ofthe said levers is provided with a handle 21. Y

` Slidably mounted between the inner members 12 and parallel therewith, I have provided a bar 22, the upper end of Vwhichis pivotedly connected to the central portion of each olthe levers 18. The bar 22 is of a length equal to the inner members 12, and has provided at its lowerend a plate 23 adjacent to each of its sides so as to overlap the inner edges of the members 12. 'Ihese plates Jform a guide for holding the member 22 in proper alinement. Each of the edges not the member 22 ynear its lower end is formed inclined inwardly until they reach a point beneath the plates 23. The edges then 'are inclined outwardly so that a head 2d is formed on the lower end of said member 22, as clearly shown in dottedv lines in Figure; 2. This head is designed to rest normally adjacent to the inner'edges of thelower ends of the inner members 12, the

head being of a width equal to the width oic the upper end of the bar 22, and when the said head 24 is so spaced the inner members V12 are parallel with each other.

- By moving the handle portion Yof the levers 18 downwardly, it will be seen that thefbar 22V will be moved downwardly which will cause the head 24 to be moved i Vdown below the lower endszof the adjacent members 12 to a position as shown in eir-v tended dotted lines. This 'will permit the inner lower corners of the members 12 to rest against the narrow portion of the member 22, said portion being indicated by the numeral 25, thus permitting the lower ends of the inner members 12 to swing inwardly about the pivot members in the bar 15, and the inner `plates 11 Vto disengageV their respective wall members 10.

This downward movement of the Jfree end or the levers 18 will also. cause [the upper ends of the outer members 12'to be swung inwardly a slightdistance, thereby causing the lower ends of said outer members to be moved outwardly as the. bars are swung about the bolts 16 and the outer plates 11 to disengagethe outer faces of the walls 10.

The frame members together with the plates 11 may then be easily and quiclrly moved upwardly until their lower edges rest near the upper edges of the wall members, after which the levers 22 are elevated. This will cause the lower ends of the outermembers 12 to move inwardlyr and the head 24s to be moved upwardly, whichwill cause the lower ends of the inner members 12 to be moved outwardly.r

For locking the upper ends ci? theouter end ot a toggle lever 31, the said toggle 23.1

being arranged to lock the plates 27 in position 1n the notches 26, as clearly shown in Figure 2.

f yIhen'it is desired to release the bars 27,

the operator grasps the central portion of the toggle 31 which he elevates and which in turn moves the upper ends of the members 27 inwardly until they disengage the notches 26. The levers 22 and the bar 18 may then be operated as before described.

Byproviding the

openings

20, 17 and 28,

kI have provided means whereby the outer members 12Amay be adjusted to Yform walls of di Ierent widths.

`When` the members 12 have been placed outwardly from the positionv shown in Iigure 2 by placing the

bolts

16 and 19 into other openings, it--willbe seen that `the upper ends of the members 17 willnot engage the notches 26, so I have Vprovided openings 28 to permit the bolts 27a to be moved outwardly a distance equal to that in which the members 12 are moved outwardly. The boltsBO are then removed andplaced into other openings 29 closer to the bolts ,'27n which provides also for the outward ladjustment or the members 27, and at the Sametime enables the voperator to use the same toggle member 31. In building foundations, it is often desirable to make one or both of the wall members 10 considerably thicker than the wall portion above the foundation. ThisV can, ol course, be accomplished by adjustingthe bolts before described. When it is desired to build the upper wall narrower than the lower wall, the outer members 12 may be set closer together. f

Inorder to malte anniform offset in the youter face-of either ot the walls, or both` into a portion 33 parallel with the upper portion 31a, this device being clearly shown in Figure 4. Suitable bent Vplates 34 fare substituted for the plates l1. ArIhe bar 31a may be substituted for one of the outer bars l2. After the oii'set portion of thewall has.

been constructed, the outer members 12,1nay be again replaced.

For'fforming the upper edges of the end walls to conform with the slant'of the roof, I have provided openings 35. These lopenings are arranged in inclined rows at each of the members l1. These rows are of the same pitch as the root' to be constructed. Each 'of the openings or' the single row is designed toreceive a rod 36 which extends between two mold members used to form each side of the wall, as clearly shown in Figure 5, and. serves the purpose of forming a guide for the mason when the concrete is being poured between the said molds. The concrete is poured so as to aline with the said rods, after which the rods may be removed when the concrete has set slightly and the said inclined upper edge may then be troweled smooth if so desired.

By this arrangement, it will be seen that'I have provided means whereby the proper inclination to the upper edge of the roof portion ot the walls may be easily and quicklyl formed as the concrete may be A poured between the rods.

By this arrangement, it will be seen that I have provided a clamp frame for wall molds which may be easily and quickly applied, and when applied will be rigidly held in position, and alsoY which is capable of being adjusted to walls of different widths.
