HANGER.

Specification of Letters Patent.

Patented Jan. 1, 1918.

Application filed April 4, 1917. Serial No. 159,812.

To all whom it may concern:

' Be it known that I, WILLIAM .B. MAR- Un'r'rn, a citizen of the United States, and a resident of Yonkers, county of WVestchester, and State of New York, have invented a new and useful Improvement in Hangers, of which the following is a full, clear, and exact description.

My invention relates to improvements in hangers such as are adapted to be used in connection with inserts in cement ceilings or the like. For structures which do not have exposed beams or supports for hangers, it is customary to use metallic inserts or devices which have a keyhole slot in the bottom, and a supporting bolt or hanger of some kind is placed in these inserts, and the hanger so placed is adapted to support electric light fixtures, shafting hangers, or other things that it may be desired to support. A common difliculty in this form of structure has been that if a hanging device is made easy of insertion in the insert or support, it has frequently been of such a structure that it would almost as easily let go, and sometimes such devices have worked their way out of the supporting ledges near the slot of the insert and dropped whatever they have been intended to support. The object of my invention is to overcome this difliculty and produce an extremely simple and convenient hanger which can readily be applied to inserts of the character named, and which when so applied cannot accidentally let go. In carrying out this idea I can use a cheap and simple form of hanger, but I shape the head so that by tilting the hanger it can be readily inserted in the slot of the insert, but I provide the hanger with an offset head so that when the hanger is in its vertical position, the elongated offset portion of the head will in case the hanger slides, strike the upright wall of the insert and prevent the head from working loose, which will be clearly understood from the description which follows. It will be clearly understood that the lower part of my improved hanger can be made in any approved shape or with any approved means of connecting it with the various articles to be supported, such electric light fixtures, shafting hangers or the like.

Reference is to be had to the accompany ing drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a broken side elevation partly in section showing how the hanger is applied to an insert.

Fig. 2 is a similar view but shows the hanger suspended in a vertical position.

Fig. 3 is a similar view but showing another shape of the lower part of the hanger, and i Fig. 4 is a plan view of the structure shown in Fig. 2.

The hanger has a body portion 10 which for many purposes'is made hollow as shown in Fig. 4, and provided with an internal screw thread as shown by dotted lines at 11 inthe same figure, so that the pipe or other thing can be screwed into it, but as above stated any form of connection betweenthe member 10 and the article supported can be used without aifecting the principle of the invention. For electric light fixtures this form is desirable, however, and it has a side opening 12 so that the cables 13 can issue laterally from the bore of the member 10. The body portion 10 has preferably a reduced shank 14, and this has a head 15 which is preferably fiat on the under side, is wider than the shank, and is offset to a considerable extent as shown in the figures. This head is adapted to enter the keyhole slot 17 of an insert 16, and slide along and be supported on the ledges 18 in the narrow part of the slot.

I have shown a standard insert 16 such as is generally used in cement ceilings or the like, and the lower portion of the insert is customarily left flush with the lower face of the ceiling, the whole insert being embedded in cement. In the drawings I have not carried the cement body to the top of the figure, but it will be understood that the insert is applied as usual.

When the hanger embodying my invention is applied it is tipped as shown in Fig. 1, and slid diagonally upward through the wider part 17 of the keyhole slot, then tipped into a vertical position as in Fig. 2, and moved along till the side bottom portions of the head 15 rest firmly upon the ledges 18. It will be noticed that the length of the head 15 is longer than the wide part of the slot 17, so that if by any chance the hanger moves longitudinally in the insert, the outer end of the head 15 striking the end wall of the insert 16 will prevent the hanger from moving any farther, and it cannot possibly drop so long as its vertical position is maintained.

In Fig. 3 I have shown another form of hanger in which the body portion comprises a bolt 19 which can be provided with a nut 20 if desired, but the head portion 15 is as already described. This emphasizes the point which I have already made, that while for electric light fixtures the forms shown in Figs. 1, 2 and t are desirable, still my inven-. tion cc-vers a hanger having the peculiar head which I have shown, without reference to the body structure of the hanger.

It will be noticed that the hanger which I have shown and described can be applied to a standard insert, that it is cheap and simple, easily applied, and that it cannot accidentally work loose.

I claim 1. The combination with an insert adapted tobe embedded in a ceiling with its lower face substantially flush with said ceiling and having a keyhole slot in the bottom, of a hanger having its upper part suiiiciently narrow to slide in the narrow part of the keyhole slot, and having a head broader than the narrow part of the keyhole slot and elongated in one direction so as to project across the wider part of the slot and strike the end Wall thereof.

2. The combination with an insert adapted to be embedded in a ceiling Wall and provided with a keyhole slot in the bottom part thereof, of a hanger. having its upper portion adapted to slide in a narrow part of the keyhole slot and having a head Wider than the narrow part of said keyhole slot and elongated in one direction.

3. The combination with an insert having a keyhole slot therein, of a hanger having a shank to enter the narow part of the, aforesaid keyhole slot,and a head Wide enough to straddle the narrow portion of said keyhole slot, and elongated in the other direction to an extent exceeding thewidth of thebroad part of the keyhole slot.

4. The combination with an insert adapted to be embedded in a ceiling with its lowfer face substantially flush with said ceiling,

and having a keyhole slot in the bottom, of;

a hanger having its upper or head portion wider than the narrow part. of the key hole slot and broad enough to span the Wider part of the key hole slot, whereby it is necessary to tilt the hanger to place it in or.
