JOINT FOR ROOFING 0R LIKE Si-XEETS Filed Sept. 27, 1951 IN V EN TOR.
Patented Oct. 6, 1953 UNITED STATES ATENT OFFICE 3 Claims.
The present application relates to modifications of the structure of a joint for roofing or like sheets, disclosed in my co-pending application, filed January 28, 1948, Serial No. 4,761, now Patent No. 2,571,273, granted October 16, 1951.
The present invention has substantially the same objects in view as stated in my said copending application.
The invention consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.
In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views;
Fig. l is an end view of a joint made in accordance with the present invention; and
Fig. 2 is a perspective view of a pair of metallic sheets with preformed joint edges in the position immediately preceding to their interengagement and interlocking.
Referring to the present drawing in detail there is shown therein a pair of sheets l and I I. marginal edge of sheet I0 is suitably formed for effecting a complementary part of the joint to be engaged by a complementary part of the joint formed at the marginal edge in sheet I I, in order that the two parts may interengage and interlock when the sheets are brought to an edge to edge relation. Said complementary part of the joint in sheet It! includes hook I2 which is formed out of the body of sheet III by doubling the same upon itself for effecting stem I3, and hook proper I I, which extends from said stem I3, and is inclined toward the body of sheet III, for the purpose hereinafter described.
The free marginal portion of sheet I0, past said hook I2, is rolled in an upward direction for defining a substantially cylindrical rib I5, the free edge of said rib I overhanging said hook I2, and with stem I3 thereof substantially defining a peripheral continuation of the body portion of said rib I5. It is noted that the hook proper I I extends outwardly of rib I5.
The marginal portion of sheet II is suitably preformed for engaging and interlocking the same with the joint part of sheet I0 hereinabove described. Said marginal portion of sheet I I includes an arcuate, upwardly projecting portion I6, from which flap IT projects on a plane substantiallly parallel with the continuation plane of the body portion of sheet I l, as is clearly seen lnFig. 2.
The
The free edge of said flap I7 is bent downwardly, and then into a reverse direction in parallelism with the body of said flap H, for the purpose of defining hook I8. To engage sheet It with sheet II, rib I5 of the former is brought under flap II and toward the upper, arcuate portion I6 of sheet II, until said rib I5 contacts with said portion I6, as seen in Fig. l. Thereupon flap I1 is bent downwardly and around said rib I5, and hook I8 is forced in engagement with hook proper I4, as seen in Fig. 1. When hook I8 engages hook proper I4 the joint parts of the two sheets will be interengaged and interlocked, and will form a seal quite impervious to water.
If desired, filler I9, which may consist of a cylindrical rod made of wood or any other suitable material, may be inserted within rib I5 and left in the joint for adding thereto a degree of rigidity, and preventing denting of the joint. Filler I9 may be used in the process of formation of rib I5 and thereupon left therewithin.
Optionally strip 20, made of rubber or any other impervious flexible material, may be rigidly ailixed to rib I5, in a longitudinal relation therewith and along the uppermost point of its periphery, for providing a seal between the said rib and the contacting inner face of the outer cylinder defined by said flap I! when the latter is bent around said rib I5, as seen in Fig. 1, thereby preventing seepage of liquid, such as water, which may otherwise enter the joint and pass below the plane of sheets III and I I.
Although rib I5 preferably is of an annular formation on a transverse cross section, it is understood that it need not be restricted to that formation, but may be polygonal if desired. Flap I'I, however, should be preformed to correspond to the formed contour of rib I5 in order that the two may closely contact.
To maintain hook I2 rigidly in its formed formation, and prevent its distortion when under engagement by hook I8, the base of stem I3 may be spot welded, as at 2 I.
The two sheets I0 and I I, with the joint therebetween may be rigidly affixed to the roof base in any suitable manner. If desired, angle iron 22, in a longitudinal relation with the joint aforesaid may be affixed to sheet II, by spot welding 23, or other suitable means. Said angle iron 22 may then be super-imposed upon joist 24 and engaged therewith by any suitable means.
While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be 3 made therein without departing from the spirit and scope of the invention as claimed.
What I claim as new is:
1. A joint for a pair of sheets along their contacting edges comprising a generally cylindrical rib extending along one edge of one of said sheets, a hook projecting from the surface of said sheet and on the same side thereof as said rib, said hook being turned away from said rib, an arcuate upwardly extending marginal portion along the edge ofthe other of said sheets, a flap extending from said arcuate portion and in an integral relation therewith, and a hook extending along the marginal free edge of said flap, said hook being turned toward said arcuate portion in position to engage the hook on said first mentioned sheet when said flap is bent in an embracing relation with said rib.
2. A joint for a pair of sheets along their cons tacting edges comprising a generally cylindrical rib extending along one ed e o one fea deheets.
1a hook projectin from the su iac of sa d sh et, the stem of said hook being substantially onthe peripheral arc oi said rib, the hook proper being turned'away from said rib, an arcuateupwardiy extending marginal portion along the edge of the other-of said sheets, a fiapextending from said arcuate portion andin an integral relation therewith, a hook extending along the marginal free edge of said flap, said hook beingturned toward said arcuate portion in position to engage the hook on said first mentioned sheet when said flap is bent in an embracing relation with said rib, and sealing means extending along said rib and located between said rib and said flap.
3. A joint for a pair of sheets along their contacting edges comprising a generally cylindrical rib extending along one edge of one of said sheets, a hook projecting from the surface of said sheet, the stem of said hook beingsubstantially on the peripheral arc of said rib, the hook proper being turned away from said rib, an arcuate upwardly extending marginal portion along the edge of the other of saidhsheets, a flap extending from said arcuateportion and in an integral relation there- "With,-?and .a hook extending along the marginal free edge of said flap, said hook being turned toward said arcuate portion in position to engage ar und- A B CK E- MQQ LL U H- References Cited in the file of this patent UNITED STATES PA'I'ENTS Number Name Date 1,021,844 Moomaw Apr. 2, 1912 2,571,273 McCullough Oct. 16, 1951
