4 Claims.

My invention relates to building construction and particularlyjtoa pressure relieving and wall strengthening joint. a

Among the objects, of my invention is to provide a pressure relieving and wall strengthening joint having a unitary structure thereby eliminating. the necessityof fillers; to create a joint formed ofa single sheet of material, andhaving a plurality of integral raised portions adapted to be forced down by excessive; weight to relieve pressure; to supply a joint adapted to be folded on itself to produce a water tight course, and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing preferred embodiments of my invention, yet I wish it understood that the same are susceptible of modification and change without departing from the spirit of my invention.

Referring to the drawing, Fig. 1 is a plan view of one embodiment of my compressible filler before it is bent for use; Fig. 2 is an enlarged sectional view of the form of my compressible filler shown in Fig. 1 and now folded in use in building construction; Fig. 3 is a perspective view of a different embodiment of my compressible filler partly unfolded.

The form of my compressible filler as shown in Figs. 1 and 2 comprises a body member ll adapted to be bent back on itself preferably at 22 to form an upper portion or layer l3 and a lower portion or layer l9; A plurality of spaced raised portions 20 all preferably of substantially the same height are integral with lower layer 59. The upper layer 20 has no raised portions and is uniformly level. When my compressible filler is bent back on itself at 22, the upper layer substantially covers and is superimposed over said lower layer thereby contacting the raised portions of said lower layer. 7

The form of my compressible filler shown in Fig. 3 also comprises a body member ll having a central portion 29 having integral therewith a plurality of spaced raised portions 20. On either side of said central portion 29 and integral therewith, is a level portion 28. Said body member I1 is adapted to be bent back on itself at both places indicated at 32, the meeting places of the central with the level portion on either side thereof, so that the level portions 28 substantially meet to substantially cover said central portion 29. When said level portions 28 are superimposed over said central portion 29, said level portions 28 contact said raised portions 20.

It is within the contemplation of my invention that in both forms that the structure may be reversed, so that the raised portions may be integral withthe upper portion ill or portions 28 instead of the lower portion 19 or central por- 5 tion 29 which, would in that case be level.

While I prefer to construct my joint or filler of ductile metal such as lead, or, fiber, rubber or the like, yet it is within the spirit of my invention to construct my joint of any compressible mate- 10 rial having substantially the same qualities as lead. My invention providing for a joint of one piece of material eliminates the necessity of expensive fillers. By eliminating the need of any filler and making my joint of one integral part, 15 I substantially decrease the cost and amount of material and labor.

While I have shown as illustrated in the drawing raised portions in circular form, yet I wish it understood that my raised portions may be 20 in the shape of squares, triangles, rectangles, bumps or any other form of raised portions without departing from the spirit of my invention.

My joint may be used in any type of building construction and particularly where the con- 25 struction is divided into zones. My joint may be placed in any place and as many times as desired within each zone and at any place between units of a wall.

The raised portions are of any desired height, generally of sufiicient thickness to create a joint of equal thickness to the mortar joint. One purpose of the fold is to produce a water-tight course. My joint comes in any desired width, and is delivered on the job out to fit the profile 5 of each individual pier, thereby eliminating any additional expense in setting. My joint is of sufficient strength to carry the normal weight expected to occur on the facing units.

In all buildings of stone, terra cotta, granite 4.0 or marble facades certain destructive movements occur which cause the facing blocks to crack or spall. These movements include: the compression of steel, the expansion of stone due to temperature change, wind-stress, settlement, 45 and vibration. These conditions are. frequently aggravated by faulty setting. To overcome any disastrous results from the above movements my joint has been developed to incorporate a feature of elasticity into the wall which may not 50 be obtained as well in any other manner. When the excessive weight is placed on the facing blocks there is relief provided simply by the raised portions of my joint being forced down, which automatically restores the desired, intended 55 weight to the facing material. With the use of my joint the building is zoned into story heights. Where the stones are. bonded onto the floor or in the use of shelf angles, this material permits these types of construction to function as intended by assuring, for the life of the building, that the weight of the facade will rest on either the angle iron or the floor. Another desirable feature of my invention is the elimination of substantially all future tuckpointing.

My invention herein is new and differs, from my copending application on a patent for Building construction, Serial Number 91,520, filed July 20, 1936 in that I have now provided that the raised portions on my joint are formed in only one of the upper or lower portions, whereas in my said previous application the raised portions occurred in both the upper and lower layers. With my new construction I eliminate the raised portions on either the upper or lower layers thereby saving considerably in expense, material and workmanship as well as saving the necessity of constructing the raised portions on boththe upper and lower layers so that they may nest or meet. I also provide that the upper or lower layer may be in a pair of flaps instead of a centrally bent portion.

Having thus described my invention, I claim:

1. A unitary compressible filler for use as a pressure relieving joint in a wall structure comprising a sheet of material adapted to be bent upon itself to form an upper layer and a lower layer, only one of said layers having raised portions so that when said sheet is bent back upon itself one layer will contact the raised portions on the other layer.

2. A compressible filler for use as a pressure relieving joint in a Wall structure comprising upper and lower metal members, one of said members having a plurality of raised portions, the other of said membersv having no raised portions, so that when one of said members is positioned above the other of said members, the raised portions of one member will contact the other member having no raised portions.

3 A compressible filler for use as a pressure relieving joint in a wall structure comprising a sheet of metal folded to form upper and lower layers, and interposed spacing means comprising integral raised portions on only one of said layers.

4. A compressible filler for use as a pressure relieving joint in a wall structure comprising a single pair of oppositely disposed metal members, only one of said members having raised portions, said portions adapted to withstand a desired dead weight without substantial compression but adapted to be compressed by excessive pressure.
