W. n. HAM. MOLD FOR FORMING WALLS.

'jw/vewfoyf APPLICATION FILED MAY29.1906.

UNI E srA'rEs PATENT OFFICE.

"WILLIAM 1). HAM, OF KNOXVILLE, TENNESSEE.

I mom Foe FORMING WALLS.

To "all whom it may concei'r'tl'f Be it known that WILL IAM D. Him, a' citizen of the United States, residing at Knoxville, in the county offKnox'and State'ofTennessee, have invented new and useful Im provements in Molds for Forming. Walls, of which the following is a specification;

This invention relates to molds for forming The wall maybe composed of any desirable material-such as concrete, cement, or-

. other like substanceand I use in the formamemberand t tion of the Wall mold means of advantageous construction. The wall is composed of inner and outer sections, an air space or cavity in? tervening between the two. This air-space is a confined air-space and insulates the exterior of the wall from the interior thereof and also prevents the conduction of water from the exterior of the Wfitll to the interior. Any water applied to the exterior surface ofthe wall cannot pass entirely therethrough, but can only go to the air-space, which causes a downfiow of the water. Both sections of the wall f are simultaneously built up and are seamless or jointless, and in thisres ect are distinguished from walls made 0 brick, blocks, or other like articles which are ordinarily held together. by mortar. Itherefore provide a double preventive of moisture traversi the wall, one being due to theabsence of joints in; the sections of the wall and the other beingdue to the dead-air 'space between said sections.

A wall made m accordance with my 1nvention possesses all the strength and lasting] qualities following a wall made of bricks or:

blocks. 3

The mold for forming the wall usu ally comprises two inner members and two outer members, which may be made ofmetal or i' wood, or they'may be of composite construction, as may be desired. I find,'.however, that galvanized sheet metal is quitesatis'lac tory for these sections. The .members are arranged in cooperating pairs, one inner member .bein arranged opposite one outer I16 same being the case with the other two members, by reason of which cement can be introduced into the spaces be-- I tween the said inner and outer members to form the sections offthe multipart wall, the

space between the two inner members defining the air-space between tllGWttll-SGOUODS. Iprovide means of a positive character for.

holding these moldmembers in rigid rela- I) out the several figures.

requisite distance a art and also prevent them from longitu inal,and other movements. The articl'e made in accordance with tiontliat is to say, I hold them spaced the the invention is a monolithical insulated wall.

In the drawings accompanying and form-' ing a part-0f this specification, Figure 1 isa vertical section of a wall'and. a mold for ma the same involvin my invention. Fig. '2 1s "a side elevation of t e same. Fig. 3 is a top plan view of the parts shown in Figs. -1. and 2 with the deflector omitted. Fig. 4 is a detail view in pers ective of a' spacing member. Fig. 5 is a ik'e view of a tyingstrip. Fig. 6 is a similar view of a scaffoldsupporting bracket. Fig. 7 is a detail view in perspective of a key, and Fig. 8 is a like View of a modified form of tying-strip.

Like characters refer to like parts throughwhat has been'hereinbefore briefly stated itis'believed that it willbe understood that the.

space defined by the two inner members 2 constitutes the or insulating space between thetwo sections of the wall.

Of course the wall may bemade of any desirable numv bers of sections, although the wall shown is only com osed of two. upper r'ndldwand a lower mold, e'ach'includin the four members described. 7

In making a wall with my mold I usually in some suitable manner simultaneously buildthe two sections thereof a short distance above" the ground or substantially-to In Fig. 11- show an where the horizontally-disposed tyin -strip 4 is illustrated as located in Fig. -1. then place along the upper side of the two parallel sections one or more of said strips 4, which I refer to make from galvanized sheet metal- The ends of these strips extend outward beyond the inner and outer surfaces of the wall, so as to afford a support for they outer .mold members 3, the inner mold members 2 being supported by the'strips 4 between-the ends thereof; I may punc from the strips 411pper and'lower teeth or projections, as 5 and 6,

' slots near theextreme outer ends of said strips of outer notches to receive the outer mold' his, as 7, which I generally make of wedge orm, so as to avoid the necessitydf roviding extraneous means for holding said pins in lace. I then set the mold members 2 and 3 on the anchoring or tying strips 4. l pins 7 will prevent outward displacement of the lower portions of outer members 3,while a spacing member, as 8, will prevent inward motion of the members 2. After setting'th'e lower sections of the inner and outer mold members upon the lowermost horizontally alined, strips 4 I place the spacing member 8 into the space between the inner members 2 and 3 and'introdu'cethe upper edges of said 5 members 2 and 3 into to r notches, ea'ch designated by 9, in the ca 10 of said spacing member. The spacing member 8 and its head may be integral and may consist. of galvanized sheet metal. Two of the notches 9 are formed in the head'lo-imme'diately next the spacing member 8. Really the side edges of said spacing member constitutes the inner wall of such inner notches, into which inner notches the inner mold members 2 are fitted. There are a series of these notches 9 in the outer portions of the head 10, into any one of each of which the respective outer mold members 3 may fit. By providing a series members 3 I adapt the appliance to making walls of varying thicknesses. The spacing member 8, withit's head 1 0, present s "astr'ucture of substantially T form. After mounting and properly s' acing the severai mold members 2 and 3 I h l in the cavitiee between such inner and outer mold members with cenanchorin gstri s.

crete or cement in a lastic cmidition and build up the same to t e to s of said members, leaving, however, sma lspace'sfor thev l I then withdrawthe spacing mem ers and afterward lift the inner mold membe'rs 2 from lace, following whlch I lay across'the tops 0 the outer mold members several of the strips} in vertical line with the s aces left for thefm in the wall, and-fasten t ese strips permanently in' place by I a small amount of concrete, so that such series of strips can be employedto sustain the up per series of mold me bers 2 and 3; (Shown in Fig. 1;) I leave t e outer moldmemh'ers 3'temporarily in positiomso that-workmen cannot deface the wall. The oupe memb'ers 3 (shown in the left in Fig. 1) may have beads as 3, on their inner surfacesto form in the wall a brick or block like effect. I K The ends of the strips 4 which project beyond the exterior surfaceof the wall may be,

as shown in Fig. 1 utilized for's'upporting an-' gle-brackets, as 11, which may be employed for carrying the-scaffolding-boards-used by the wor en in construction of the wall.

I may, as represented in Fig. l by full lines and by dotted lines in Fig. 2, mount centrally the inner and outer mold members 2 and 3.

It will be understood that in Fig. 1 I have shown'tw'o 'selparate molds, which are used in succession, a though when I use the second mold or the u perofne in said figure I leave the outer members of the lowermold in place. so as to prevent defacement or injur to the opposite faces of the wall. As the e evation of the wall progresses the molds are moved upward therewith, and the scaffold-brackets 11 are also lifted step *by step- When the brackets are detached from the strips 4, I

provide means for preventing outward displacement of the lower members 3 'of the mold, which fit against the exterior surface of the wall. For example, it will beassumed that the brackets 11 have beentaken from the lower strips 4 and have been ap lied to the upper strips 4 in said Fig. 1. In t is case there will be spaces between the wedge-pins 7 and the said lower mold members 3, and

' naturally there will be a tendency for the said members 3 to tip. T'o obr iate this, I drive onto the left pro ecting ends of thesaid lower strips 4 ke s or washer-plates 4"of bifurcated form, the ranches of these keys or washerplates '4' beingadapted to straddle the left projecting ends of said strips 4 and to tightly fit in the spaces between the pins 7b'n the left and the lower members 3 on the left.

whereby it will not be possible for said members to be acc dental y displaced. I mar I also apply these washer-plates or'key's 4' to the right ends of the strips 4, which is of utility in holding longitudinally-abutting members 3 in place, thekeys covering the-joints between such abutting members. i

It will be understood that the teeth or roj'ectioiis5 and 6 are embedded in thewal so as to permanently unite the strips 4, of which said teeth form a part, with the wall. After a mold has been dismounted and after the pins 7 have been pulled from place the ex treme outer ends 0 the strips may be sheared or cut an to bring the ends of the strips flush with the wall, 'o'r said projecting ends may be bent dew nw'ard and pressed into the wall and afterward. covered over with cement, which I Willbe-dressed down flush with the remaiilder of the wall. Insome cases, if'd'esi'red, the

strips 4 may be perfectly lain or smooth, so

that they can be driven om the wall; In this event these strips would simply serve to aid in holding the mold members 111 operative as that included in my-copending 'applicaposition. Should" I employ such plain or the cement as the wall is in process of consmooth'strips, I will prior to applying them in the wall slightly envelop them with oil, which will deaden the cement around them, by reason of which they can after they have subserved their function of upholding and maintainingin operative relation the mold members and also supporting the scaffolding be driven from place and the apertures made by themin thewall closed by cement or concrete.

anchoring-strips, as 14, for performing the function of said spacing members 8 and holding the mold members in position'and maintaining them in spaced relation. This modified form of strip 14 has the projections 5 and 6, which perform the exact office as the projections or teeth 5 and 6 hereinbefore described, and illustrated in Fig. 5 in detail. In addition to these projections or teeth 5 and 6 the strip 14 has on its sideedges the upwardly and downwardly extending proj ections or barbs 15 and 16, respectively, and which are situated between the teeth 5 and 6,. The side faces of the inner mold members 2 are adapted to abut against, these barbs, while upstanding barbs, as 17, formed near the outer ends of said strip 14, perform a like office with respect to the outer mold members 3. The strips 14 are slotted at their outer ends to receive wedge-pins, as 7, hereinbefore described.

In my claims for convenience I use the ter cement. I use this term in a broad sense to include not only the article so known, but other substances, such as concrete material or, in fa'ct,.anything that can be employed for making a wall or equivalent part.

I deem it desirable to state that the present invention is along the same general lines tion, Serial No. 318,586, filed May24, 1906.

As previously explained, the strips 4 in some cases may be perfectly plain. When plain or smooth, they do not remain perma-' nently in the wall. There are cases where thesections of a multipart wall are required to be tiedtogether-for example, where suchf In such ani event as this I may tie the sections of the wall together, not by plain strips, but bywall is of an unusual height.

other and shorter strips, which are laid in the wall during its course of construction. These tying-strips will be like the strips shown in Fig. 5, extept that they will beshorter, so that their ends will not project from the opposite faces of the wall. I 7 It will be remembered that I-have stated that the o posite ends of strips 4 or the strips 14 may w en the wall iscomplete becut off or maybe bent down into the wall and the bent-down ends covered with cement.'. To facilitate the latter operation, I will place in There are cases, such as when building walls around pilasters, that I may. employstruction blocks which may be conveniently made of wood, which when removed form under the free or' outer portions of the strips 4 or 14 cavities in the outer faces of the wall, and in these cavities the outer ends of said strips 4 and 14 may be bent downward, the

cavities afterward being filled with cement,

which .-covers the bent-down ends of said strips. a

What I claim is 1. A mold comprising at least two inner members. and two outer members cooperative respectively therewith, strips extending.

across the upper and lower edges of said members, and a spacing member disposed between the inner members. I

2. A mold comprisingat least .two inner members and two outerlmembers cooperative respectively therewith, strips extending across the upper and lower edges of said members, and a spacing member disposed between the inner members, said spacing member being provided with means for positively holding the several mold members in parallelism.

3. A mold comprising at least two inner members and two outer members cooperative respectively therewith, and a spacing member between the inner members provided with means .for positively holding said membersin operative relation.

4. A mold comprising at least two inner members and two outer members cooperative respectively therewith, a spacing member situated between the inner mold. members and provided with a head having notches to receive theupper edges of the several 'mold members. i

5. A mold comprising at least two inner members and two outer members cooperative respectively therewith, and a s acing member between the inner members aving a head, said head having notches to receive the inner members and having two series of notches, each one of which latter is adapted ber situated between the inner members and having ahead provided with means to positively hold the several members in assembled relation, and a deflector carried by thehead to positively direct cementmaterial into the spaces between the inner and outer members.

7. A mold comprising inner and outer members cooperative respectivelywith each other, strips extending entirely across and projecting outward beyond the upper and ower edges of the mold to constitute scaffoldsup orts, said strips having pin-receiving p'e orations' near their outer ends and have mg projections to prevent outward displacement of the outer mold members, and a l In testimony whereof I have hereunto set spacing device between the inner mold meml my hand in presence of two subscribing witto bers. nesses.

.8. A mold comprising inner and outer .members combined with a, part to extend WILLIAM across said mold members and having notches Witnesses: to receive the said mold members and hold HEATH SUTHEBLAND, the same in parallelism. CHAS. S. HYEB.
