(Cl. 85v2`.4)

3 Claims. l

My invention relates to anchoring devices of the type employed for attaching objects to walls made of concrete, brick or the like.

One of the objects of my invention is to proivide an anchoring device of the class described which shall be of such improved con-struction that the object may be attached to a wall even when the attaching holes therein do not yline up exactly with the anchoring device inserted in the wall, allowing for variations of alignment in all directions.

Another object of my invention is to provide an anchoring device of the class described which shall comprise relatively few and simple parts, which shall be easy yto assemble and use and which atV the same time shall possess a high degree of efficiency and effectiveness in use.

Still another object of my invention is to provide anranchoring device of the class described which shall be lso constructed and arranged that objects attached to the ceiling thereby and depending therefrom will be plumb even when the attaching holes in the object are not in exact alignment with the anchor device in the ceiling.

Further objects of my invention will become apparent in the detailed description thereof to follow or will be hereinafter pointed out.

In the accompanying drawing,

Fig. 1 is a cross-sectional view through a portion of a wall showing the anchoring device of my invention in position for effective use;

Fig. 2 is a front elevational view thereof;

Fig. 3 is a View taken substantially along the line 3-3 of Fig. 1;

Fig. 4 is a cross-sectional view similar to Fig. 1, but illustrating a modified form of my invention; and

Fig. 5 is a view taken substantially along the line 5-5 of Fig. 4.

Referring now in detail to the drawing I have shown a wall anchoring device constructed and arranged in accordance with my invention and illustrating the same as inserted in a wall W in the customary manner of inserting anchoring devices. The wall W may be of brick, concrete or any other well known wall materia1 and the anchoring device comprises a tubular member I0 of rigid metallic material of the nature of iron having a through axial opening II. The member ID is provided, at its inner end. with an enlarged outwardly flared end Illa. The wall portions I 0b and IIlc, extending from the flared end Illa to the outer end, surrounding the opening I I are outwardly tapered, as shown, the purpose and function of which will soon become apparent.

2- The portion Ind of the wall surrounding the opening II at the junction of the end Illa and tapered wall portion Iilb is concaved to serve as a seat for a correspondingly curved portion I5a' of the enlarged head I5b of a rigid metallic member I5 freely received within the opening II. It isl noted that the shank portion of the member I5 is provided with an internally thread-Y ed axial opening I6, and that the outside diameter of the said shank portion is considerablyv less than the opening II so that it may move freely therein. The enlarged head portion |51) limits the axial movement of the member I5'. Due tothe mating seating arrangement of the correspondingly curved portions I5a and Ind, the member I5 may pivotally move in all direc-V tions, providing a universal mounting for the member I 5.

The shank portion of the member ID may -be surrounded'by a soft metallic sheath 25, as is known and customarily employed in the art, for retaining the member I0 rmly in the wall W.`

To attach an object to the wall W by means of the anchor device just described it is merely necessary to pass a suitable screw 25 through a corresponding attaching opening in the object and thread the same in the threaded opening I6 of the member I5 as clearly shown in Fig. 1 of the drawing. The enlarged head I5b of the member I5 will hold the said member captive, while the head of the screw 25 will maintain the object against the wall W.

In accordance with my invention, as above described, if the opening in the object through which the screw is passed is out of alignment with the opening 20 in the member I5, the said member I5 will adjustably pivotally move itself within the opening II and thus the object may be attached without drilling new openings in the object or removing and repositioning the anchor device.

It is also noted that should the anchor device be positioned in a ceiling or top wall for the pur-4 pose of hanging an object therefrom, the said object will always hang straight and in plumb due to the construction of my anchor device as described above which permits universal free movrlnent of the member I5 within the opening To provide a better frictional grip of the head I5b of the member I5 against the seat IIId, when the screw 25 is tightened, I may provide circumferentially spaced ribs I9 on the convexed portion I 5a of the member I5.

In Figs. 4 and 5 I have shown a modified form o1'. my invention in which the construction of all the parts are identical with those illustrated in the Figs. 1 to 3 form of invention except that the opening 3l in the member 30, corresponding to the opening I6 in the member l5, runs axially clear through the said member 30 and a countersunk portion 32 is provided in the enlarged head portion of the member 30. In this form of my invention a screw member 40 is inserted in the opening 3l from the inner end before the anchor member is inserted in the wall W, the head 40a thereof being received in the corresponding countersunk portion 32 and the shank portion of the screw 40 extending beyond the Wall W. This extending shank portion of the screw 40 is adapted to pass through the opening in the object and a nut 50 and Washer 5l placed thereon to hold the said object in iirm attachment to the wall W. In this form of my invention, as in the Figs. 1 to 3 form, the member 30 is freely mounted for universal pivotal movement to compensatingly adjust itself to disalignment between the opening in the object and the axis of the opening of the anchor device in the wall W.

In accordance with the provisions of the patent statutes, I have herein described the principle and operation of my invention, together with the construction which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction can be carried out by other means. Also While it is designed to use the various features and elements in the combination and relations described, some of these may be altered and others omitted without interfering with the more general results outlined, and the invention extends to such `use.

Having described my invention, what I claim and desire to secure by Letters Patent is:

1. For use in attaching an object to a wall or ceiling, an anchor device of the character described comprising a relatively rigid first tubular member, a soft metallic sheath surrounding said rst tubular member, the said rst tubular mem- 4 ber and sheath being adapted to be received in an opening in said wall and frictionally retained therein, the inner Wall of said i'lrst tubular member having a relatively enlarged head portion at the inner end thereof and a relatively constricted portion, the said relatively constricted portion being tapered outwardly from said head portion to the opposite end thereof, a second rigid member comprising an enlarged head portion and a shank portion, said second member being disposed within said first member with the enlarged head portion of said second member nested within the enlarged head portion of said first member and with said shank portion nested within the constricted portion of said rst member, the enlarged head portion of said second member being larger than said constricted portion of said rst member whereby the axial movement' of said second member will be limited in an outward direction, the size of said shank portion of said second member being such as to provide a free space between the outer wall thereof and the inner wall of said constricted portion of said rst member to permit free adjustable angular movement of said second member with respect to said' first member for the purposes set forth and means for attaching an object fastening screw member or bolt to said second member.

2. An anchor device according to claim 1 in which the enlarged head portion of said second member is provided with a plurality of ridges tov the opening in said second member,l the head of' said bolt resting in the enlarged head portionrof` said second member. y.
