Description
June 26, 1962 J. CAMERON LOCKING DEVICE FOR CONCRETE FORMS INVENTOR. 1! J55 CAME/90M Ammwzx Filed NOV. 14, 1960 United States i' atent 3,040,410 LOCKING DEVICE FOR CONCRETE FORMS Joe Cameron, 2630 N. Evergreen, Phoenix, Ariz. Filed Nov. 14, 1960, $91. No. 69,167 1 Claim. (Cl. 25-131) This invention pertains to locking devices for concrete forms and is particularly directed to self-locking apparatus for such forms.
One of the objects of this invention is to provide a locking device for the various panels of a foundation form which is quick and easy to apply and remove and is automatically self-locking.
Another object is to provide a foundation form locking device for automatically locking the form panels together accurately in both longitudinal and transverse position.
Still another object is to provide a foundation form locking device which'simultaneously locks the panels endwise, laterally, and in proper lateral spaced position by a single downward movement of the clamp on the form panels.
Further features and advantages of this invention will appear from a detailed description of the drawings in which: i
FIG. 1 is an enlarged fragmentary plan view of the locking device for concrete forms incorporating the features of this invention.
FIG. 2 is an enlarged transverse section on the line 2-2 of FIG. 1.
FIG. 3 is an enlarged plan view of the clamp.
FIG. 4 is an enlarged side elevation of the clamp.
FIG. 5 is an enlarged end elevation of the clamp.
FIG. 6 is an elevation of the outside of two of the panels of the foundation form.-
As an example of one embodiment of this invention, there is shown in FIG. 6 a representative panel 10 for making up the foundation form. This panel comprises the horizontal base angle member 11, theinter-mediate horizontal angle member 12 and the top angle member 13 to the ends of which are welded the vertical end angle members 14 and 15. Suitably fixed to the inside faces 16 of the angle members 11, 12 and '13 is a sheet of plywood or the like 17. Perforations or nail holes 18 are formed in the horizontal leg 19 of the base angle 11 so that the panel it) may be placed on a base strip 20 which is first nailed to the footer 21 upon which the stern of the foundation is to be poured. Suitable duplex pull-out nails 22 are then driven through the nail holes 18 to secure the bottom portion of each panel to the footer 21, as best shown in FIG. 2.
It is to be noted that the upper ends of the laterally disposed legs 23 and 24 of the end angles 14 and 15 are formed with wedge-shaped notches 25 having vertically disposed front sides 26 and upwardly inwardly sloping rear sides 27 terminating in a crotch defined by the horizontal bottom edge 28. A clamp 29, FIGS. 3, 4 and 5, comprises the horizontal portion 30 which may vary in "ice panels 10. Extending upwardly from the lower edges of the downwardly extending portions 3-1 and 32 of the clamp 29 are notched 36 having sides 37 and 38 and the bottom edge 39. After the form panels are initially set on the footer 21, FIG. 2, the clamp 29 is placedin position with the faces 33 and 34 of the portions 32 of the clamp wedging down between the sides 26 and 27 of the slots 25 to thus align the panels laterally and provide the proper spacing between the inside and outside forms for the width of the foundation to be poured on the footer. At the same time the sides 37 and 38 of the notches 36 engage the outside faces 40 and 41 of the legs 23 and 24 of the end angles 14 and 15 below the bottom edge of length to suit the desired width of the foundation to be the notch 25 to lock the panels 10 together longitudinally. Thus, all panels are simultaneously locked together and properly spaced by the application of the clamp 29. Suitable turnbuckle adjustable stay rods 42 may be used to accurately position and support the forms in correct vertical position.
While the apparatus herein disclosed and described constitutes a preferred form of the invention, it is also to be understood that the apparatus is capable of mechanical alteration without departing from the spirit of the invention and that such mechanical arrangement and commercial adaptation as fall within the scope of the appendent claim. are intended to be included herein.
Having thus fully set forth and described this invention what is claimed and desired to be obtained by United States Letters Patent is:
A locking clamp device for simultaneous coupling concrete forms in lateral spaced position and in longitudinal alignment and abutting end contact comprising in combination:.
(a) a clamp having,
(b) a horizontal portion having a length to suit the desired width of the foundation to be poured,
(c) downwardly extending integral wedge-shaped ends.
having outer faces disposed parallel to the inner material engaging faces of the form panels and upwardly inwardly sloping inner faces adapted to engage References Cited in the file of this patent UNITED STATES PATENTS Babel Apr. 119, 1910 Cornelius J an. 25, 19-16 Peterson et a1 May 3, 1932 Hyre Nov. 18, 1952 Arrighini Dec. 20, 1955 I FOREIGN PATENTS Great Britain Mar. 2, 1955
