INVENTOR ATTORNEY Aug 18; 1931. M. E. MURPHY Filed Feb. 19 9 2 Sheets-Sheet 2 ATTORNEY Patented Aug. 18, 1931 UNITED STATES MARTIN E, MUEIPHY, OF WEST I-ALM BEACH, FLORIDA FORM Application filed February 19, 1930. Serial No. 429,707.

The object of this, my present invention, is the provision of a form for constructing concrete butteresses for sea walls-whereby plastic concrete may be poured into the form in an easy manner, and wherein the form, after the concrete is set may be readily removed and arranged at a different place along the sea wall.

A further object is the provision of a form for this purpose that is constructed of fabricated steel that is, all the elements thereof are constructed of steel plates which may be removably associated so that the form can be expanded or contract-ed, and further wherein the form is of such construction as to provide the buttress with steps, if desired. i

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in 7 connection with'the accompanying drawings which form part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

" In the drawings:

Figure 1 is a plan view of the improvement.

Figure 2 is a perspective view thereof.

Figure 3 is a side elevation thereof.

Figure 4 is a sectional view approximately on the line H of Figure 2.

Figure 5 is a side elevation to illustrate a slight modification.

Figure 6 is a sectional View approximately on the line 6-6 of Figure 5.

In order to resist the power of the waves which are thrust thereagainst sea wall buttresses are necessarily substantially V-shaped in plan and, of course, are arranged at an inclination, being inclined upwardly from their lower or pointed ends to their connection with the sea wall proper. The angle sides of the buttresses thereby resist the force of the water thrust thereagainst. Thus, in carrying out my invention the form which I eni-' ploy for constructing buttresses for sea walls is V-shaped in plan and is arranged at an angle from its center or nose portion to its upper or widened end.

' All ofthe elements constituting my improvement are of metal'of sufficient strength to withstand the strain of thepoured concrete therein and likewiseto permit of the ready removalfrom the form after the said concrete is set. The form comprises two up wardly inclined plates 1 1, respectively, and as the form is V-shaped in plan these plates are arranged at an inward angle with respect to each-other. The plates 1 on their outer 5 faces and at the edges thereof are'reinforced by angle irons 2 and the central or connecting element for the plates which provides the nose for the form comprises two spaced curved channel plates? Obviously the side To member-s1 and their'reinforcingiedges or plates 2, as well as the nose elements 3 are riveted or bolted together. The side-members 1 are in the nature of risers and the widened or spread ends thereof are connected together by the angle plates 4, and the inner flanges of theseangle plates are secured to transversely arranged ribs 6 which are preferably in the naturevof' channeled irons. I

By reference to Figure Lit will be noted that the ribs 6 are disposed a considerable distance above the lower edge of the risers 1 and that the flanges of the said ribs 6 are extended rearwardly with respect to the said risers. Securely bolted to the inner faces of the risers there are anyother desired number of transversely arranged ribs 7. These ribs 7 are also of channel irons and are arranged a suitable distance above the lower edge of the risers. The flanges of the ribs 7 are directed toward the nose end of the risers of the form and have'centrallyriveted or otherwise secured thereto the straight ends of upwardly inclined plates 8, the said plates be ing arranged between and riveted to the flat faces of channeled members 9 that afford the central element of the form. The members 8, at the lower ends thereof, are extended outwardly in a substantially horizontal plane and have fixedly secured therebeby the numeral 11, and to the outer ends of these members there is riveted a brace 12 which is also riveted to the central portion of the upper rib 6. I

It is to be noted that the horizontal flanges of the members 2 project a suitable distance beyond the risers l and these projecting portionswill embed in the sand so that the form maybe readily arranged at a desired angle with respect to the sea wall and concrete may be poured between the risers and the ribs to provide either a straight inclined surface or a stepped inclined surface for the top of the buttress. After the concrete has been set the form may be readily removed by means which engage with the openings 13 of the front plate or bracket 10 with the horizontal ends 11 of the central and reinforcing angle members 9.

If desired and asillustrated by Figuresfi and 6 of the drawings the extension plates 14: may have their lower edgesinclined inwardly below the lower angle irons 16 and the edges thereof may be notched, as at 17 to allow the same to fit the irregular surface of the steel sheet piling on which the concrete buttress is placed and to hold the same from accidental movement when the concrete is poured thereinto. .Any desired number of extension plates may be added-to the bottom of the form to encase the steel sheet piling with concrete, the extension plates being bolted together at angles. I a

As disclosed by the drawings the ribs? are disposed at a curvature with respect to the ribs 6, and the rib 7, adjacent to'the rib 6 may be connected directly thereto or these ribs may be straight'or parallel to the rear face of the wall.

This steel form is used for the molding of concrete platform orsteps which rests on the top of steel sheet piling which has been driven in the V shape as outlined by the form. Wood piling may also beused as well as concrete piling. a The construction and advantagesof the device will, it is thought,'be apparent to those skilled in the art to which. such invention relates so that further detailed description will not berequired. a

Having described the inventon, I claim:
