` METAL FLASHING Filed Oct. 22, 1930 ATMRNEY.

` Patented Feb. 99 1932 i PATENT OFFICE EDIUND H. FRIEDRICH, OF HOLYOKE, MASSACHUSETTS METAL FLASHING .Application led October 22, 1930. Serial No. 490,447.

' This invention relates to an improvement in metal flashings. i

An object of my 'invention 1s to provide a flashing for forming a water-tight joint between the top or upper surface of a wall and the coping stone. In the flashing construction disclosed in my pending application, Serial No. 405,180, filed November 6, 1929, there isshown, described and claimed a flashing having a longitudinally extending rib or struck-up portion, which is centrally located with reference to the opposite side edges of the ilashing. This rib is substantially wedge.

This construction .v

shape in cross section. v l5 permits the opposite side edges to be folded downward onto the inner and outer'faces of a wall and suitably'connected to metal coverings on these faces by means of a lock, or other joint construction.

My present invention also discloses .the longitudinally extending rib construction of the flashing, shown in my pending application and, in addition, struck-up short ri'b portions, on the opposite sides of this wedgeshaped rib portion which are located transversely of the iiashing and of the struck-up longitudinally extending wedge-shaped portion. This construction, when in use, effectually prevents a coping block trom moving or becoming displaced longitudinally of the fiashing. In my prior flashing construction, the wedge-shaped longitudinally extending rib 5 eifectually permits lateral movement of the coping. My present invention eectually permits the coping fromv movement in either a longitudinal' or lateral direction, as will be described.

Referring to the drawings:

o i Fig. 1 is a perspective view showing the top or upper surface portion of' a wall with the flashing in place and a block of coping located thereon.

'Fig 2 is a plan view of the flashingremoved, illustrating the struck-up and trans'- versely arranged projections.

Fig. 3 is a sectional view on the line 3-3 0 ofdlig. 2 showing two of the struck-up ribs, an

1 Fig; 4 is a sectional view on the line 4 4 .of Flg. 2.-

Referring to the drawings in detail l designates a portion of a wall; 2 a length of the copper, or other metal of the flashing, having the wedge-shaped longitudinally extending rib 3 with oppositely located S- shaped sides -3 and the downwardly extending sides 4, as shown in my pending application. 5 designates the transversely arranged 6o struck-up ribs which are located,as shown, on the opposite sides of the wedge-shaped rib 3. These ribs are formed with the overhanging S-shaped portions 5 which, it will be noted, extend in opposite directions (see o5 Fig. 3), whereby the coping blocks, 6, will be eifectually prevented from longitudinal movements, since the mortar, cement, or other like adhesive materialwill lill the recesses 7 and 9. These struck-up portions are 70 substantially S-shape, as shown.

In use, the iashing is first placed on a layer of mortar 8 on the upper surface of the wall. When the flashing is placed on the Wall, it is retained in place by the side lian es 4 and 75 mortar under the opposite S-shape sides of the wedge-shaped rib 3. Next a layer of mortar 8 is placed on the upper surface of the A ilashing. This will enter and fill the recesses 7, as well as the spaces 3 under the rib 3. 80 The block of coping 6 is now put in place on i the mortar 8. 'It is obvious that the block of coping `will be efectually prevented from both lateral and longitudinal movement, with reference to the upper surface of the wall; the rib 3 preventing lateral movement, and the struck-up S-shaped portions 'preventing longitudinall movement,after the mortar 8 has set. It will, therefore, be seen that I have' provided a metal flashing plate that is 00 simple and economical in `construction and one that eectually prevents a coping block from becoming displaced. A

It should also be 'stated that the mortar 8, under the flashing'plate, will enter the open- 95 ings 9 and materially assist in preventin the longitudinal movement of the flas ing I plate 2.

What I claim is: Y g 1. A sheet ofv flashing comprising a metal 2 I 1,s4s,e4e

plate having, a longitudinally extending struck-up wedge-shaped rib with overhan e ing side edges and struck-up transverse y extending ribs formed with overhanging portions to providerecesses for recelvmg 5 mortar or the like.

2. A sheet of flashing comprising a metal plate having a longltudinally extending struck-up wed e-shaped rib with S-shape side edges an struck-up transversely ex- W tending ribs formed with overhanging portions to rovide' recesses for receiving mortar or the 1i e, said overhanging portions facing in op osite directions.

3. s an article of manufacture, a flashing plate comprising a member having a plurality of transversely arran ed projections above its up er surface, sai proJectlons being substantially S-shaped in cross section.

4. As an article of manufacture, a flashing plate comprising a member having a plural- 1ty of transversely arran ed projections above its upper surface, sai pro]ect1ons being substantially S-shaped in cross section and a longitudinally extending struck-up rib substantially wedge-shape in cross section, whereby when mortar is applied to the u per surface of the flashing and a coping b ock placed thereon the block will be prevented from both lateral and longitudinal movement, as described.

5. A sheet of flashing com osed of metal, v as copper, and formed with -sha e struckup rib portions against'which a ardening materia as mortar or the like, enga es for retaining coin blocker the like in ace.
