1" b all whom it may concern Be it known that I, HERMAN MENTEN, a citizen of the United States, residing in New fork, county of Queens, and State of New York, with post-ofiice address at 4L30'Sherman street, Astoria, New York, N. Y., have invented certain new and useful Improvements in Hanger-Bolts, of which'the following is a specification. I

This invention relates to hanger bolts and particularly to bolts designed for securing various articles to walls constructed'of hollow tiles or the like.

This invention has for its object the pro,- vision of a novel hanger bolt of inexpensive construction which can easily be secured in place upon walls of diflerent thicknesses and which will securely hold the members of door frames, window frames, moldings, etc., upon the wall. I

A special object of the invention is to providea hanger bolt of such construction that the bolt itselfmay be conveniently used to mark the door facings or the like at the proper points for drilling them to make openings for the passage of the securing screws or bolts.

In the accompanying drawings, of which corresponding parts are designated bysimilar characters of reference: Figure l is a view partly in elevation and partly in vertical section showing a wall with a number of the improved hanger bolts secured thereon and showing the manner of marking the door facings for drilling preparatory to securing it on the wall. Fig. 2 is a sectional view showing the mode of introducing the hanger bolt into the opening formed therefor in the wall. Fig. 3 is a-sectional View showing the method of securing the hanger bolt in the wall. Fig. .l is a sectional view showing the hanger'boltin position and provided with a marker for the article to be held by the hanger bolt. Fig. 5 is a view in elevation showing the outer end of the hanger bolt in position and ready to receive the screw for securing the door facing or other article in position. Fig. 6 is a view in longitudinal section showing the hanger bolt in position with a pieceof door facing secured against the wall by means of the hanger bolt. Fig. 7 is a detail view in perspoctive of the inside anchor. Fig. 8. is a perspective view of a modified form of body of the hanger bolt showing the outside Specification of Lettersiatent.

; door facing or other article against the wall.

' Holes of suitable diameter are formedin the wall of hollow tiles as shown in the several figures, the-holes being of such diameter that the body of the bolt will pass easily into them. The parts of the anchor bolt having been arranged as shown in Fig. 2, the bolt is pushed forward through the hole until the parts reach the position shown in dotted lines in that figure. The inside an chor 2 will then drop down into vertical position, so that by pulling upon the head of the securing bolt 4 the inside anchor may be brought into the position shown in Fig. 3, thereby locking against the inner surface of the hollow tile. The outward pull upon the securing bolt t will also bring the nut 4 into the position shown in Fig.3, in which one side of the nut is shown seated against a shoulder 2 formed on the anchor '2. It will be'noted that the anchor 2 is provided with three openings 2 2 and 2 the opening 2 being arranged between the otheropenings and just above the" shoulder 2 The securing bolt t passes through this opening which is somewhat nearer one' end of th'e' anchor than theoth'er. This location of the opening 2? makes it impossible'for the anchor to bal a'nc'e' horizontallyon the bolt 4- and causes one end always'to' drop down into'the po} sition shown in Fig. '3, thus bringing the shoulderQ immediately below the nut 4. It will also be noted that the anchor 2 is' a stamping, preferably of sheet steel, and has edges which bite into the niaterial of the iollow tile when the anchor is drawn up against the tile as shown in Fig." 3.

To se cu're' the hanger bolt firmly after drawingthe anchor 2 into position sh'owniii F 3, the outside anchor 3 is"pressed against the outersurface of the wall thus' forcing the body 1 which slides freely on-the bolt 41am the opening in the wall." The anchor 3 is then held in position with the fingers of one hand while the bolt 4 is screwed up into securing position with the fingers of the other. The final turns on the The body 1 of the hanger bolt has two parallel openings, 1 and 1 extending through it. The larger of these 1 is not threaded and is providedfor the passage'of securing bolt 4, the other opening 1 is threaded to receive a screw. In securing the hanger bolt in position inv the wall, care must be taken to prevent the outside anchor 3 from extending across the outer end of the opening 1 and it is desirable to secure the body of thehanger bolt in the position shown, in with thetwo longitudinal openings arranged in the samezhorizontal plane. When the parts of the hanger bolt are-secured in the position shown inFig. 4, the marker 6, in the form of pointed screw is secured in the opening 1 leaving the point exposed as shown in'Fig. 4. When a long piece of material is to be secured to the wall by means of several hanger bolts, all the hanger bolts required should be placed in position before the material to be secured is applied to the wall. Each hanger bolt should beprovided with a marker, as shown in Fig. 1, and the material to be secured placed in position and pressed against the several markers, In this way the relative positions of-the holes-for the securing screw will be plainly marked and these holes can be drilled with certainty. After the neces sary holes have been drilled in the article to be secured upon the wall, securing screws 5 will be passed through the openings in the article to be secured and screwed into the openings 1 in the bodies of the hanger bolts as shown in Fig. 6, thus securing the article firmly against the wall.

While it is desirable that the body 1 of the hanger bolt should be of a length approximating the thickness of the wall to which it is to be secured, it will be clear that this is not necessary, the length of the bolt 4- being such that the hanger bolt can be secured in a wall whose thickness is considerably greater than in the wall, and it is desirable that the opening. be of such size that the body portion of the hangerbolt will fit solidly in is substantially flush the opening when the outer end of the body of the wall.

Should it be desired. to remove thehanger the bolt t until the parts can be drawninto the position shown in Fig. 2, which can be facilitated by passing some narrow body, such as a piece of wire, through the open portion of the opening for "the bolt and tilting the inner anchor 2 into thev position shown in Fig. 2 of the drawings. The bolt can then be withdrawn without difficulty.

The form of the body'for the hanger bolt shown in 8 is especially adapted for use in. comparatively thick walls. Here the outer anchor 3 is rigidly secured to the body 1 of the hanger bolt, thus making it impossible for the body to be forced too far into the opening in the wall. y

Elaving thus described my invention wli at I claim as new and desire to secure by Letters Patent is; l

1. A device of the character described comprising a body of substantially circular cross section. adapted to fill and fit a drilled hole in a wall, a bolt extending through the body for securing it in place, an inside anchor loose on said bolt and adapted to be brought approximately into alinement with said bolt withoutremoving it from the bolt, anoutside anchor carried by said bolt for clamping said wall and maintaining said body in said hole, and means co-acting with said body for securingdoor facings or the like in place.

2. A device of the character described comprisinga body member adapted to fit a drilled hole in a wall and having a hole therethrough, a bolt mounted in said hole, inside and outside anchors on said bolt adapted to be drawn together by rotation of said bolt to hold said body in'position, and means for attaching a door facing or the like to said body member. I

8. An anchor bolt for wallsfcomprising a body member having a marking point cletachably mounted therein, a bolt passing through said'body member, and anchorscarried by said bolt for engaging the inner and outer surfaces of the wall.

In testimony whereof, I have signed my name hereto in the presence of witnesses.
