EXPANSION SHIELD.
' Application filed May 14, 1925. Serial No. 30, 150.
This invention relates to improvements.in
andarranged as to possess superiorgripping qualities.
Another object of the invention is to pro vide an expansion shield adapted to be used with "and expanded by a driven expanding eleniient.
Further objects of the invention will ap pear from the following"specification taken in connection with the drawings, which form a part of this application, and in which:
Fig. 1 is a sectional elevation of a wall opening having disposed therein an expansion shield. constructed in accordance with the invention, the expanding member being positioned at the entrance to the shield.
Figs. 2, 3 and 4 are transverse sectional elevations taken substantially on lines 22 8'3 and -i1 of Fig. 1.
Fig. 5 isan end elevational view of the outer end of the shield.
Fig. 6 is a view similar to Fig. 1', but showing the shield expanded.
liigs. 7 and 8 are t'ansverse sectional clevations taken substantially on lines 7-7 and 8-8 of Fig. 6.
Fig. 9 is a longitudinal sectional elevation of another shield constructed in accordance ing forced by the expanding member into a hrm gripping engagement with the wall,
opening. The angular portion may be square as shown. The shield is preferably used in conjunction with a driven expanding element,such as a nail. V the invention will apppear from the follow ing description.
In the form of the invention illustrated in r the shield 15.
Further details of Figs. 1 to 8 inclusive, the shield comprises a pair of sections 10 andll connected at tilBll. inner ends by a bridging portion 12.
The-outer endsof the sections 10 and 11 are flanged as, shown at 13, 13 and 14%, 14. The
'flan es at each section are: se )arated bv a a: j l
v shaped notch since this facilitates bending and minimizes distortion of the metal when the metal is bent toform the flanges.
The Qouter portion or the portion ofthe shielddisposedat the outer-lend of the opening is preferably formed cylindrical as shown at 15. The inner portion of the shield shown in Figs. 1 to 8 is angular in section, the two angular portions 16 and 17 forming a square when the shield is not expanded. I 1 r The object 20 to be supported by the. shield is provided with an opening 21 preferably of such diameter as to receive the shield and the object is positioned between the shield flanges 13, 18 and 141-, let and the-wall in which the shield is inserted.
ilheexpanding member illustrated in the drawing consists of a nail having a head 2:") and a shank 2(5 and the shank preferably has a diameter slightly greater than. the internal diameter of the cylindrical portion of Thus when the nail is driven into the shield asshown in Fig. 6, the cylindrical portion 15 aswell as the angular portion 16, 17 will be expanded. It will be understood that the expansion of the angular portions as shown in Fig. 7 forces these portions into firm and secure gripping en; gagement with the wall opening and that those portions perform the main gripping .lunctio-n of the shield.
The construction shown in Fig. 9 is similar to that shown in the preceding figures but 9 the outer portion of the shield is cylindrical and the inner portion is angular in cross section. r
In Fig. 10 each section of the shield is U- shaped instead of V-shaped as in Fig. 3.
Although certain specific embodiments of the invention havebeen'particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement otthe various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
What- I claim is:
1. An expansion shield formed of relatively hard metal of uniform thickness comprising a pair of sections, each bent outwardly at one end to form parts o't an interrupted flange of single thickness, curved transversely through a portion of its length and bent transversely through another portion of its length to form together a cylindrical part and a square part with flat sides.
2. An expansion shield formed of relatively hard metal of uniform thickness comprising a pair of sections, each bent outwardly at one end to form parts of an interrupted flange of single thickness, curved transversely through a portion of its length and bent transversely through another portion oi its length to form together a cylindrical part and a square partwith flat sides, the ends of said sections being notched to facilitate bending.
8. An expansion shield -formed of relative- 1y hard metal of uniform thickness comprisingga pair of sections, each bent outwardly at one end to form parts of an interrupted eeann flange of single thicknessat the outer end of the shield, curved transversely through aportion of itslength and bent transversely through another portion of its length to "form a. cylindrical part and a square part with flat sides, the ends of said sections being notched to facilitate bending, said sections being connected at their inner ends by an integral bridging portion. 7
4t. An expansion shield formed of relatively hard metal of uniform thicknes comprising a pair of sections, each bent outwardly at one end to from parts of an interrupted flange of single thickness, curved transversely through a portion of its length and bent transversely through another portion of its length to form a cylindrical part and a square part with flat sides, the ends of said sections being notched to facilitate bending combined with an expander having a diameter larger than the internal. diameter of the cylindrical part of the shield and a head adapted to overlap and reinforce the interrupted flange.
In witness whereof, I have hereunto set my hand this 11th day of May, 1925.
RALPH E. OGDEN.
