It-has been found to be advantageous to cover or'protect the free ends of flashingsor roofing l0 materialfrom rain or from waterv collecting on roofs. Protection of thezfree ends of the flashing prevents water leaking between the dashing and the wall, and serves to makethe roof "water tight.

Referring'to the drawings in detail, in Fig. 1 atwalllof a building or structure is denoted by the 50 numeral' I0; Setiny the wall lll is a raggl'e block |21which maybe. made in any convenient size or' form'.V Apreferredtype is one which isthe same size aslone or'morewhole-building blocks. This permitsthe blockxtobe inserted inthe wall easily 55v and quickly as the bricks are laid. An inclined portion I4 on the upper side of the front face of raggle block I2 acts to turn the rain. The front portion of the block I2 extends down to form an opening I6 to receive the flashing or roofing material I8. On the under side of the front portion of the block I2, a groove 20 may be formed to prevent water on the front of the block I2 from getting into the opening I6, since the water will drip off as it reaches the groove 20. The flashing or roofing material I8 may be inserted in the opening I6 and held there by a plastic material 22. Any suitable plastic material such as tar, pitch, or asphalt may be used. The plastic material is used to fill the opening I6 and to prevent Water from getting over and down behind the flashing and roofing material I8. Because of the design of the front of the block, it can be seen that a plastic is not necessary since the low hanging portion 23 of the front of the block prevents any water from splashing onto the ends of the ilashing. Where especially heavy rainfall is experienced, however, it might be advisable to more positively seal the flashing in the block by filling the opening with any suitable plastic. The rear edge of the opening I6 in the raggle block I2 may be set flush with the front of the wall Il). This will permit the flashing I8 to be held at against the wall I0 without bending it. The absence of a bend in the 1 roofing material or ashing I8 insures a much longer life for the flashing and less likelihood of failure in the roong job. The bottom of the front portion 23 of the block I2 in the preferred form of the invention is in the same plane as the bottom of the block I2. This will allow the block to be piled with other blocks Without fear of breakage, as would be the case if the front portion projected below the plane of the bottom of the block I 2.

In Fig. 2 a raggle block 24 is shown which is particularly applicable to floored or tiled roofs used on roof gardens. The top of the face of this block is set flush with the wall I0 and the lower portion of the front of the block I2 is arranged to form an opening I6. The front portion or face of the block overhangs the roofing tile 26 and acts as a watershed. The ilashing I8 may be inserted in the opening I6 and held there by the tile 26. A plastic may be used to seal the space between the tile and lower end of the front of the block I 2 if desired but this is not necessary since the tile and the block fit close enough to keep out the water. Even if the ltile does not obstruct the opening I6, the low face on the block will keep water from spraying onto the top of the flashing. The groove 20 in the front portion 28 of the block 24 causes any water collecting on the lower side of the block 24 to drip off and keeps water out of the opening I6.

In Fig. 3 a portion of an optional forni of block 38 is shown which makes use of two wedges to hold the flashing I8 in place against the wall. The front of the raggle block 3|] may have an inclined portion 32 at the top which acts to turn the rain, and a lower portion 34 which forms an opening I6 in the block into which the flashing I8 may be inserted. The walls of the opening I6 are preferably made rough so that the

wedges

36 and 38 will hold the flashing I8 in place without slipping. The wedges are made to fit together in such way that no water can get into the opening I6, and over and behind the ends of the flashing I8. The groove at the bottom of section 34 acts to keep water on the front of the block from getting into the opening I6 and causes it to drip off.

Fig. 4 shows a portion of another optional form of block 40. This block may have an inclined face 42 which acts to turn water and also to form an opening 44. Into this opening the flashing I8 is inserted and held by a Wedge 46. 'Ihe use of a wedge avoids the use of plastics such as tar, pitch, or asphalt. These substances are dirty and sticky and are not easily applied, while a wedge can be driven inthe opening 44 with little diiculty. The use of the wedge makes the flashing job cleaner and simpler. The walls of the opening 44 are made rought so the wedge and the flashing will not slip. The read edge of the opening 44 is set flush with the wall I0 so the flashing does not have to be bent. Since the flashing I8 is straight, its life will be longer andthe efliciency of the roong job will be greater.

Fig. 5 shows another form of flashing block 48 in which an inclined portion 50 of the iront of the block 48 acts to turn water and to protect the ends of the flashing. The front of the block 48 extends downward to form an opening 52. The flashing I8 may be inserted in the opening 52 as shown by dotted lines or it may be cut off `below the opening 52. When the flashing extends into the opening, the form of the block 48 is such that even without the use of plastics or other means to close the opening 52, water cannot get behind the flashing. The block is set high enough above the roof level that the water on the roof will not rise far enough to reach it, while 'the lower portion of the face of the block extends down to prevent spray from the roof from reaching the ends of the flashing. The groove 20 in the lower portion of the front of the block 48, as before, keeps the water on the front of the block from getting into the opening 52. Where the ends of the ashing do not extend into the opening 52, the flashing piece 54 prevents water from reaching the ends of the flashing I8. A roller 55 and the flashing piece 54 are inserted in the opening 52 as shown in solid lines in the drawings. The roller is permitted to rest against the inclined face of the opening and the front of flashing piece 54. The weight of the flashing piece will pull the roller 56 down into they position shown in the dotted lines and Wedge the flashing piece 54 in position. The top of the flashing piece 54 and the roller 56 t together and act to keep Water out of the opening 52. The roller 56 and the flashing piece 54 keep the ends of the ilashing I8 dry and, therefore, keep the roof water tight. j

Fig. 6 shows a block which does not require the use of a plastic such as tar, pitch, or asphalt to hold the ends of the flashing. This is done by a spring 62 which bears against the projection 64 of the block and holds the flashing I8 against the wall 68.` This arrangement avoids the use of plastics which are dirty and dilcult to apply. The design of the block holds the flashing against the wall and the front portion of the block prevents spray from the roof from touching the top of the ashing. This provides a simple method of waterproofing the flashing or roofing material.

The use of raggle blocks made in accordance with this invention does not necessitate the bending of the flashing or roofing material. Such bending not only weakens the roofing material but is inconvenient Where the line of flashing blocks is horizontal and the roof slants. The cutting and bending of the roofing paper is bothersome and is avoided by the blocks made in accordance with the invention. e roofer need only hanging front portion has a number of advantages which the raggle blocks now in use do not have. One of these advantages is that the block may be used with metal flashing Without any bending of the flashing. This minimizes the installation diiculties which are novv met in roofing jobs making use of metal flashing. Whereas it is necessary to bend the metal flashing when it is used with the blocks now in use, it need only be tted into the blocks made in accordance with the invention. Not only is it difficult to bend metal flashings, but the bending of the flashing will injure the galvanizing or other protective coating on the metal and lshorten the life of the flashing.

Another advantage which this block possesses over the blocks now in use is that the receptacle for the flashing is built in the form of an overhanging portion. The use of an overhanging portion permits the main portion of the block to be made as strong as any building block since there is no opening in the main portion. This permits the raggle block to be used in any wall and not reduce the structural strength of the wall.

The use of a block which has an overhanging portion makes a roofing job of very attractive appearance. It avoids the visible openings now used on raggle blocks and the dirty appearance of the plastics used in the block. In the raggle blocks made in accordance with the invention, the opening is in the under side of the block and not visible. Because of this a smooth, uninterrupted front of pleasing appearance may be made for raggle blocks. This is a very important factor in roof gardens Where the surroundings must be pleasing to the eye. The use of raggle blocks made inv accordance with the invention permits a Water tight roong job which is very clean and pleasing to the eye. l

It can be seen that raggle blocks made in accordance With the invention possess numerous advantages over and above the advantages possessed by the blocks now in use.

Whereas I have described a preferred form of my invention, it is obvious to persons skilled in the art that various changes and alterations can be made in the structure and form of the invention without altering 4its scope.
