MOLD FORM FOR PLASTIC MATERIAL.
Application filed February 9, 1925. Serial no. 7,878.
This invention relates to mold forms for plastic material and has special'reference to outer forms and' cores that may be advantageously used in the formation of founb dation walls, particularly walls having footings and basement windows.
The primary object of my invention provide metallic forms that may be easily and quickly installed to form a mold into m which concrete or other plastic material may be poured, tamped and seasoned to form substantial well finished walls, which may be solid or hollow, depending upon the character of the building to be supported by said walls; i
.' Another object of this invention is to provide wall forms and positive and reliable means for connecting said forms to maintain the same in perfect alignment and proper 2o spaced relation so that there may be no bulging or displacement during the placing of concrete in the forms.
A further object of my invention is to provide novel spacing members that may be anchored relative to the ground to brace the forms and hold the same in defined positions.
A still further object of this invention 'is to provide a core that may be easily posi- 8 tioned in' a form and maintained therein during-the pouring of concrete to eventually form a vertical passage in a wall.
The above and other objects are attained by construction which will be hereinafter specifically described and then claimed, and reference will now be had to the drawings,
. wherein- Figure 1 is a perspective view of forms assembled to provide a mold for the formation of a foundation wall,
Fig. 2 is-a plan of the same; Fi 3 is a cross sectional view taken on the line IIIIII of Figure 2 Fig. 4 is an enlarge cross sectional view of a form connecting device;

Fig. 11 is a cross sectional view of a mold with a core therein;
Fig. 12 is a" side elevation of a core partly in section; and
Fig. 13 is a horizontal sectional view illustrating a modified form; of connecting device.
To form a foundation wall of considerable depth, forms are placed in superposed relawhen a comparatively low wall is to be forined it may be only necessary touse my footing forms, and in either instance the configuration of the forms depends on the nature of the wall to be constructed. In the majority of instances a foundation wall has angular portions, pilasters, abutments, window openings and the like, and in such instances the forms areshaped so that eventually a desired wall is produced.
Gonsidering my forms from the ground up, there are outer and inner forms 1 and 2 which are placed in vertical parallel relation, and said forms have the lower edges thereof offset as at 3 for the formation of a footing 4. The ofiset portions 3 of the forms have lateral flanges 5 adapted to rest on the ground 6 and support the forms substantially vertical. The upper edges of the forms are beveled, as at7, and provided with v lap strips 8 so that upper wall forms 9 and 10 may be set down on the lower forms 1 and 2 as a continuation thereof, as best shown so in Figs. 1 and 10. As before stated, the forms 1, 2, 9 and 10 may be angular for the formation of a cornerwall or may be flat for the formation of a straight wall, or may have extended ortions 11 for the formation of a pilaster, a utment or the like. Where the vertical edges of the forms] are to be joined said edges are beveled, as at, 12 and provided with lap strips 13 which are of such dimensions as not to interfere with the horizontal lapfstrips 8. For retaining the upper and lower forms in spaced parallel relation, connecting devices are employed at, suitable places throughout the formation of a wall soas to revent bulging or spreading of opposed forms when concrete 1s poured 1nto the forms; Each connecting device comprises a hollow conical member 14. provided with endv shoulders: 15, neck port ons 16,
and aper- 110 members may have dowel pins to fitin tured heads 17. The outer and inner forms are provided with transverse aligning openings 18 toreceive the Shoulders 15 at the ends of members 14. To assist in correctly positioning the members 14 and prevent rotation thereof, the ends of said openings provided therefor adjacent the openings 18 of the outer forms 1 and 9.
After the conical members 14 are placed in position, forked wedges 21 are driven down over the neck portions 16 between the forms 1 and 2 and the heads 17, as bestshown in Figs. 1 and 4. The wedges 21 are formed with blow heads 22 adapted to be struck when driving the wedges into position, and on the outer faces of said wedges are lugs 23 to facilitate extracting or removing the wed es.
To brace t e forms relative to the ground tie rods 24 are employed, said tie rods having hook shaped ends 25 to engage in the a ertured heads 17, and the opposite ends 0 said tie, rods are formed with heads 26 to engage in he keyhole shaped openings 27 of stakes 28 ich are driven into the ground in a slantingposition: The stakes, similar to the wedges 21, have blow heads 29 and extracting lugs 30. The tie rods 24 are of various'lengths and are provided-with turn- I buckles 31 for drawing the rods taut after being anchored.
As shown in Figure 1, the forked wedges 21 alone may be used, especially in connection with the upper forms 9 and 10, and
- in some instances the neck portions 16 of the v modate tapering keys 32, as shown in Figs' 1 and 13.
For connecting and holding. horizontal.
Some of the upper forms 9 and 10 may be constructed to provide a window opening 42 having a lintel and sill. This is best shown in Figs. 1 to 3 inclusive.
Between the forms that provide the mold walls may be placed, at suitable intervals,
removable tapering hollow cores 43 adapted to have the lower ends thereof driven into the ground 6, as best shown in Figs. 11 and 12. The upper open ends of the cores have interior apertured lugs 44, and in these lugs are placed the depending spacing pins 45 of a spacing member 46 which has its ends mounted in apertured lugs 47, carried by the forms 9 and -10 at the upper edges thereof. The cores 43 will'therefore be braced within the wall mold and concrete can be safely poured around the same. When the cores are removed there will be vertical passages in the foundation wall which may be used for various purposes.
When the foundation wall is to be constructed in a trench 48, retaining plates 49 may be placed in the sides of the trench with the lower edges of the plates resting on the flanges 5 of the forms 1 and 2, and said plates may bear against the earth forming the side walls of the trench to prevent earth It isv thought that'the utility of my foundation wall mold will be apparent withoutfurther description, and while in the drawings there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such variations and 'modifications as fall within the scope of the appended claim.
What I claim is': A foundation wall mold comprising opposed forms havingofiset and'flanged lower edges for the formation of a footing, a
connecting member "extending through said" forms, and forked wedges mounted on the ends of said member against said forms.
In testimony whereof I aflix my signature.
FRANK J. GREMEL.
