This invention relates to snow guards which are applied toroofs, particularly of the sloping'type, and particularly those surfaced by courses of slate; tile, wooden or Such-snow guards are' for the purpose 'ofholding back and'break- 1 ing up snow and ice which' forms on such:

be made of sheet material as far as possible.

for lightness and cheapness.

The purpose of this invention is to form a snow guard of sheet metal which is econo- P mized as far as possible without the sacrifice of strength or appearance.

In the drawings, Fig. 1 is an elevation of the rectangular sheet metal blank from which the device is formed. I

Fig. 2 is an elevation of the blank as it is first cut.

Figs. 3, 4, 5, 6, 7 and 8 show the successive vendings to make the completed article.

Fig. 9 is a side elevation of the finished 35 snow guard.

Fig. 10 is a perspective from the front of the finished snow guard.

Fig. 11 shows a blank cut in a slightly different way. I

Fig. 12 shows the first bending of the blank shown in Fig. 11.

Fig. 13 shows the complete snow guard formed from the blank shown in Fig. 11.

Fig. 14 is a side elevation of Fig. 13 from '45 the left.

In the drawings, A represents a rectangular sheet of metal, preferably copper or galvanized iron, having the top 14 bottom 13 and sides 10 and 11.

i In Fig. 2 is shown the medial vertical cut 20, the two sides of which, 23 and 24, .are spaced apart the cut running vertically downward dividing blankA into the right and left sections C and B. I

At the bottom of cut 20 extending a short distance to the right is a cross cut, the bot-' tom line of which i's indicated at 29 and the top line shown-as extending,diagonallyup to the left shown at 25. Y s v In Fig. 3, Ishowthe lower left corner of left section C bent upon a diagonallin'e 28 toform a double thick triangular supporting web F thetop edge being indicated at- 129 and the side by 27. T

, The left section '0 together with web F are now bent back 90 on a vertical-line .58

extending down medially from the bottom edge 29 of the cross cut 26.

The left section C and Web F are then bent forward 180 on the line 57'which extends vertically downward from the right end of base 29 of cross cut 26parallel with the line 57, the various bendings being so positioned that as shown in Fig. 5, the left section C now extends directly forward at right angles to the attaching section B and approximately in the middle thereofv Section C is now bent to the right at 44 forming a plate'40 thence to the left at 42, theplate 40 being bent'down to the position shown at 41 in Fig. 7 and this part .41 with r the part 46 lying underneath it. is bent over on the line 43 so that it extends to the right beyond the part 47' ofsection C, all the bendings being so positioned as to form a plat-- form which is double thick at the rightand triple thick at the left.

The supporting web F is double thick while the attaching part B from which preferably is cut a hook H in a well known manner, is single thick.

As shown in Figs. 11, 12 and '13 I may use a blank andcut the vertical line 60 from a point about two-thirds to theleft thence at the bottom extend the cross cut 61 half way forming a platform section K and'attaching section'L and the bottom section M.

The lower left corner is bent up on'the diagonal line 62 forming a supporting web P having a topedge 63 and back edge 64.

The parts K and Pare now bent forward and the top part of the section K is 'bent to the left on the line 65 forming a plate 66, thence again to the right on the line 67 forming the top plate 68,. thence again down to the left onthe line 69 form ing a bottom plate 70. g

It will be seen that a platform Nis thus formed which is double thick while theweb P is also double thick. It will be observed that in this last construction there is: a gap indicated by 159 all.

siderable to include the thickness of the end of a shingle.

On the other hand, as shown at 59 in Fig.

9. the gap may be very slight or nothing at If the lines 57 and 58 arecaused to coincidethe gap 59is entirely closed.

I claim:

1. it snow guard formed of a single sheet of metal, cut medially and vertically downward forming right and left sections connected at the bottom, a cross cut extending at the bottom short distance to the right the lower left of the left section being bent on a diagonal line to forma double thick triangular supporting Web, the web and left section being bent back ninety degrees on a vertical line extending down medially of the cross cut, and thence forward on a vertical line from the right end of the cross cut to extend ninety degrees forward, and the left section being then bent right and left to form a platform resting on the top of the web. 7

2. A snow guard formed of a single sheet of metal, cut medially and vertically downward forming right and left sections connected at the bottom, a cross cut extending at the bottom a short distance to the right, the

lower left of the left section being bent on a diagonal line to form a double thick trie angular supporting web, the web and left section being bent on a vertical line from the right end of the cross cut to extend ninety degrees forward, and the left section being then bent right and left to form a platform resting on the top of the web.
