concnn'rn MOLD.

Application filed July is, 1925. Serial No. 44,458.

My invention relates to im rovements in concrete molds especially adapted for the construction of chimneys and ject the provision of an improved mold of this character adapted and arranged to position reinforcing memberstherein.

Other objects appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part hereof and in which,

Fig. 1: is a top plan view of a mold embodying the invention.

Fig. 2; an enlarged partial transverse sec tion of said mold.

Fig. 3; a detached view of one of a pluralof supporting brackets employed in the mold, and

Fig. a; an enlarged detail view of the inner end of a supporting bracket employed in the construction. v

The preferred formof construction as illustrated in the drawings comprises a plurality of supporting brackets 4, each provided at its inner end with horizontally separated arms 5, having transverse perforations 6 therein for the reception of nails 7 or the like as indicated. t its outer end each of the brackets 4; is provided with a dependiiig inwardly turned arm 8 and registering notches 9, are provided as shown to engage a supporting bar 10 secured to the outer portion of the outer side 11 of an annular concrete mold 12. The supporting bar 10 is carried by suitable brackets 13 engaging suitable adjusting screws 1% mounted in a suitable frame 15 arranged over and around the mold for supporting and manipulating the same. The specific construction of the mold and the frame work for supporting or manipulating the same constitute no part of my present invention andneed no further description here.

The form of mold illustrated is an annular mold made up of sheet metal sections and arranged to form a chimney with vertical reinforcing members 16 extending vertically through the walls thereof. The brackets 1d are designed and arranged to be mounted at suitable intervals on the supporting bar 10 to project inwardly over the top of the mold' form and so that the arms 5 may be engaged around lGlllfOlClIlg. members 16 and held in place thereon by means of nails 7 passed has for its ob- 7 mold form is moved upwardly to provide for a new section and the process thus continued until the chimneyis completed. Ob-

viously, by this arrangement, the brackets 4: may be utilized as the construction continues to hold thereinforcing members 16 accurately in position as each mold section is filled. If it is desired to change the posi-" tions of the reinforcing members or the number of re nforcing members employed, 'as the building progresses, the brackets 4 may be'readily adjusted on the bar 10 to suit such variations asis desired.

Where reinforcing members of different sizes are employed the different sets of perforations 6 are utilized for the nails 7.

Yfhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of theinvention; I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my. invention, what I claim as new and desire to secure by Letters Patent is:

1. In a concrete mold the combination of a form for containing the, concrete mixture; a bracket mounted to adjust along the side and to extend over the top of said form; and means atthe endpofjsaid bracket for detachably engaginga vertical reinforcing member projecting from the top of said form, substantially as described.

2 a concrete mold the combination of a form for containing the concrete mixture and open at the top; a plurality of brackets adjustably mounted on one side of said form to extend over thet-op thereof; and horizontaliy separated arms at the end of said brackets over said form, there being transverse perforations in said arms to receive a nail or the like, substantially as described. 3. In a concrete mold the combination of an annular form for containing the con crete mixture; a supporting bar secured to the outer portion or the outer side of said tor-1n near the top thereof; a plurality of brackets, each bracket being provided With notches slidably engaging the top and bottom edges of said bar, said brackets extending thence over the top of said form; and means at the inner ends of said brackets for detachably engaging vertical reinforcing members projecting from the top of said form, substantially as described.

4-. In a co crete mold the combination of an annular form for conta ning the concrete 'slidably engaging the top and bottom edges of said bar, said brackets extending thence over the top of said form; and horizontally separated arms at the inner ends of said brackets, there being transverse perforations '111 said arms for the reception of nails or the like, substantially as described.

In testimony whereof I have signed my name to this specification.
