Abstract
Abstract The gravel stop is made of a springable material which has top and bottom portions joined by a horizontal and a sloping portion disposed therebetween. Since the material has spring characteristics, a fascia having a channel at the top and the bottom may be placed over the top edge and moved downwardly and released to have the bottom channel engage the bottom edge of the spring unit. Adhesive, nails or other attaching means may be employed to secure the spring unit to the material at the roof edge. The spring unit may be made of aluminum, stainless steel, galvanized steel, plastic and the like. A spring unit of galvanized steel was secured by Neoprene Construction Adhesive manufactured by Franklin Glue Co.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
In a spring unit forming a gravel stop at the edge of a roof made of a sheet of spring material having vertical, horizontal and angular portions forming a spring unit with top and bottom edges, means for supporting the unit along the edge of a roof on the horizontal portion with the vertical portion extending downwardly therefrom, the top of the angular portion being moved downwardly when the angular portion is deflected, and flat fascia members having channel elements along the top and bottom edges which face in opposite directions toward each other, the top and bottom edges of the spring unit extend within said channel elements when the angular portion of the spring unit is deflected downwardly and released to have the top and bottom edges thereof enter the facing channel elements at the top and bottom edges of the fascia members which are supported thereby.
Claim 2
Dependent Claim
148 words
In a spring unit forming a gravel stop at the edge of a roof made of a sheet of spring material having vertical, horizontal and angular portions forming a spring unit with top and bottom edges, means for supporting the unit along the edge of a roof on the horizontal portion with the vertical portion extending downwardly therefrom, the top of the angular portion being moved downwardly when the angular portion is deflected, and flat fascia members having channel elements along the top and bottom edges which face in opposite directions toward each other, the top and bottom edges of the spring unit extend within said channel elements when the angular portion of the spring unit is deflected downwardly and released to have the top and bottom edges thereof enter the facing channel elements at the top and bottom edges of the fascia members which are supported thereby.
Claim 3
Dependent Claim
47 words
In a spring unit as recited in claim 1, wherein the spring unit provides a bias between the top channel element of the fascia member and roofing material extending over the top edge of the spring unit when in substantially vertical position to form a seal therebetween.
Claim 4
Dependent Claim
61 words
In a spring unit construction as recited in claim 2, wherein the inner side of the channel element at the top edge of the fascia member is deflected outwardly between the top and bottom edges thereof to provide a line of engagement with roofing material extending up over the angular portion of the spring unit to provide a further seal therefor.
Claim 5
Dependent Claim
28 words
In a spring unit construction as recited in claim 1, wherein the holding means for the spring unit at the edge of the roof is an adhesive material.
Claim 6
Dependent Claim
37 words
In a spring unit construction as recited in claim 1, wherein the securing means for the spring unit is a flattened edge between the horizontal and angular portions of the spring unit through which nails are driven.
Claim 7
Dependent Claim
47 words
In a spring unit construction as recited in claim 1, wherein a plurality of fingers struck from the angular portion of the spring unit located in the plane of the horizontal portion have nails driven therethrough for securing the spring unit to the edge of the roof.
Claim 8
Dependent Claim
34 words
In a spring unit construction as recited in claim 4, wherein the horizontal and vertical bottom portions of the spring unit are provided with a plurality of apertures through which the adhesive material extends.
Claim 9
Dependent Claim
76 words
In a spring unit construction as recited in claim 1, wherein the spring unit is made from two parts, one having angular and horizontal portions, and the other a bottom vertical portion on the forward edge of the horizontal portion which are secured to the roof edge, the edges of the upper angular and lower vertical portions being engaged by the channel elements at the top and bottom of the fascia members into which they extend.
Claim 10
Dependent Claim
28 words
In a spring unit construction as recited in claim 9, wherein the horizontal and angular portions of the unit are welded or otherwise secured together when separately formed.
Claim 11
Dependent Claim
74 words
In a spring unit construction as recited in claim 1, wherein a top flange for the unit extends up from the top of the angular portion, and a bottom portion of the unit constituting said vertical portion extends downward from the free edge of the horizontal portion, the top flange and bottom portion being engaged by the top and bottom channel elements of said fascia members into which they extend to provide support therefor.
Claim 12
Dependent Claim
31 words
In a spring unit construction as recited in claim 10, wherein the top and bottom portions of the unit are in aligned relation for supporting fascia members having a plane surface.
Claim 13
Dependent Claim
38 words
In a spring unit construction as recited in claim 10, wherein the top and bottom portions of the unit are in offset relation for supporting fascia members having upper and lower surfaces in angular relation to each other.
