T 0 all whomz't may concern.'

vBe it known that I, FRANK FLYNN, citizen of the United States, residing at Newark, in the county of Essex and State ofwNew Jersey, 'have invented certain new and useful Improvements Ain lMolds for ConcreteA Structures, of which the following is a specilication, reference being had to the accompanying drawings.

The present invention has for itsnpurpose the provision of a mold for #constructing concrete, cement or other plastic-structures of a hollow type, preferably buildings, thecrete walls between the spaces, and which' intermediate walls connect with the exterior and-interior parts of the wall. Furthermore the auxiliary mold parts are capable of being easily removed, as the wall is constructed in a perpendicular direction, and adjustedy to a higher position.

A further purpose is the provision of timbers interconnected in 'super-imposed positions on the exterior, to holdk theemold plates in place, it being possible to remove the` lower timbers and raise them to higher positions, until the wall is completed to the desired height.' i W A still further purpose is 'the provision .of means for supporting the mold timbers on the upper edge of the concrete orl cement wall, as the wall is constructed.'

It is to be understood that the particulars herein given areinno way limitative and that while still. keeping within the'scope of the invention, any desired-modiications-of` detail and desired proportions maybe made in the apparatus according to circumstances.

The invention comprises further features and combination of parts, as will be herein- `after set forth, shown in the drawings and claimed.

In the drawings: i

Figure 1 is a sectional plan view, showing the constructionl and arrangement `of.` the n y mold, illustrating `the concrete, cement for other plasticmaterial as .having `been depositedtherein for-'forming the wall of a building` structure. 'f f e Figure 2 issan enlarged vdetail sectionalt plan view of a portion of the .walland the mold, showing the wedges or'spreaders `as having beenjwithdrawn from 'holding-'positions. whereby the interior moldplates for forming the air spaces may be removed.

i Figure 3 is a vertical sectional view on line 3--3 of Figure 2,' showing the constructionof the wall and mold,ishowing the superimposed interconnected timbers, for'- holding the exterior mold plates.

lReferring, to the drawings, 1 and 2" designate the interior and exterior mold plates, w

which may be any suitable pro-portions', ac-

cordingto the size .of wall or building to be constructed.l These plates are adapted to be arranged' in. parallelism, to forni the moldwalls, and 3 and 4 denote the. mold platesbfor'forming. the air spaces'in the concrete wall` 5.: Thesel plates 3 and L1sad.- )acent their vvertical longitudinal edgeson their inner surfaces have beveled ribsf.- In

spreading devices 7 `are employed-g. f Each v spreadingldevice comprise'swrods V8 having their .adJacent ends threaded, and their outer ends connected-tof vwedges or spr'eaders,y

which are'V-shaped incross section and are adapted to engage the beveled ribs 6.

beveled ribs 6, to force the plates 3 andlel These sections arel slightly tapered vertiv cally', as shown, in .fact the outer surface of each `section 'inclinestoward the inner sury face of each section at the upper endl -The lower end of each sectioniis provided with a riglitanglejcut away portion or recess 'which is of a shape 4oricontour to receive and engage the upper end of the adjacent section. \Vhere the sections of the timbers 11 interconnect in this manner, suitable bolts or screws 16 are employed, to hold the sections aligned. y

The upper sections 14 (which may act as the lower sections, when the sections 12 andv 13 are arranged above the section 14) have extending therethrough vrods or bolts 17, the nuts 1S of ywhich are adjustable on the rods, to hold the timbers inplace, and to adjust themrelatively spaced, for Lthe purpose of holding the mold plates. in position. As the concrete wall increases in height, it is necessary to remove the lower succeeding timbers,y and place them atthe top, and fur- G tliermore it is necessary to support the timbers on the wall. norderv to support the timbers, props, such as rods 19, rest upon the upper edge of the unfinished wall, and are provided with forks 20, which straddle the` rods 17. Obviously the timbers may be held in position, as the wall increases in height. As the wall is'constructed suitable tie or binding

rods

21 and 22 arearranged vertically and transversely in the outer portions of the wall of the structure, for the purpose of reinforcing t-he concrete or cement. Any form of reinforcing rods may be employed, tubular, solid orspiral rods may be embedded in the concrete or cement. Also embedded in the transverse connecting wall sections 23 are transverselyI disposed reinforcing members 24. The inner portion of the wall of the structure, adjacent the corners thereof, and adjacent whe-re the intermediate transverse wall parts are formed, vertical reinforcing rods 25 are used, which are connected to the horizontal and verticall reinforcing rods ofthe outer portion l ofthe wall, byineans of the transverse'reinforcin'g rods 24. f

VVh'en the timbers'are placedl to hold the lexterior and interior mold vplates in position, theheadsV 18 .are adjusted uponv the rods v17, and then the transverseI timbers 2G are disposed between the upper ends of the timbers 14,. in fact between the uppermost sections thereof, there being rods 27 or bolts passing through the ends of the upper sec tions, through the timbers 2G and have wing nuts or heads 28 to bind the parts inposition. It will be noted that by this construction the timbers 11 may be held equally spaced.

Then the sections of the timbers 11 are arranged in position, the recess or cut away portion 15 of each section receives theupper end of the adjacent section, it being possible to remove the bolts or screws 1G of the lower sections, whereby the lower sections may be placed in engagement with the upper sections 14.- and vice `versa as the wall increases in height. Suitable thumb screws 29 'are the sashes (not shown), and without usingl wood window frames. rEhe hollow spaces of the wall constitute means to receive the sash weights, hence it is possible to form a wall structure having window openings, without the vnecessity of wood frames (not shown). Mold sections, similar to those previously described maybe used for forming the interior separating walls between the rooms, and in sucha manner as to provide door openings, such as indicated at 83. Thesedoor openings 33 have their jambs provided withy bolt-S34 embedded in the concrete, to hold.

.wood blockings 35, for the reception of the trimmings 36.,

. A building wall of this character serves to eliminate rats and mice and other pests, from inhabiting living houses, apartments and the like. Furthermore the air spaces formed within the walls will prevent the walls from sweating on the interior. Furthermore the exterior of the wall may be stucco, but may be otherwise given a decorative effect, ras may be desired,'the top of the building, or above the windows and door, or any other place. The use of window frames may be eliminated, the. walls may be made whatever thickness desired, it being possible yto use the same structure of mold throughout the` entirewall structure. j

The exterior mold plates 2 may have different designs or impression surfaces, Aso that in constructing the wall, the exterior face of the wall may be decorated at the same time with the construction of the wall.

hold and support the door timber or frame- 36. The thumb screws 29 are swivelled in plates 29a (which bear against the' mold plates), and when the thumb screws are ro` tated or tightened, the plates bear against the lower mold plates `and hold them rin place, namely from slipping down.

The invention having been set forth, what is claimed as being useful 'ist 1. In a mold for constructing building walls, Opposed mold boards or plates spaced according to the'desired thickness of wall to be built up, tapered timber sections disposed against the outer faces of said plates and arranged vertically, the sections on each side being in alignment, the inner face of the lower end of each section being cut away to receive and engage the upper end of an adjacent section, means for fastening the sections together where they connect, a rod connecting the uppermost sections at a point above said plates and having abutment means on its ends, and means between the extreme upper ends of the upper sections for spreading said upper ends and causing the lower ends of the lowermost sections tobind against the plates. i

2. In a mold for constructing building walls, opposed mold plates, to be spaced according to the thickness of wall to be constructed, interconnected timber sections arranged vertically adjacent the exteriorsurfaces of said plates, means passing through and connecting the uppermost timber sec` tions at a point above the plates and provided with abutment devices adjacent the ei:`

terior surfaces of the timber sections, spacing devices arranged between and connecting the extreme upper ends ot the timber sections, and hold the timber sections spaced ac-` cording to the thickness of the wall,l said abutment devices being adjustable to draw the lower portions of the timber sections adjacent to and in contact with said plates.

3. In a mold for constructing building walls, opposed mold plates, to be spaced according to the thickness of Wall to be con structed, interconnected timber sections ar ranged vertically adjacent the exterior surfaces of said plates, means'passingr through and connecting the uppermost timber sections at 4a point above the plates and provided with abutment devices adjacent the exterior surfaces of the timber sections, spacing devices arranged between and connecting the extreme upper ends of the tim.- ber sections, and hold the timber sections spaced according to the thickness of thewall, said abutment devices being adjustable todraw the lower portions of the timber scc-A' tions adjacent to and in contact with said plates, props engaging the means 'which passes through and connects the timber sections to su ort the timber sections in Josition, and means connectedto and carried by the lower ends of the timber sections for` i holding theplates in position.` y In testimony whereof I hereunto atx my signature.
