JOSEPH EIRSHSTEIN, OF CLEVELAND, OHIO, ASSIGNOR 0F ONE-HALF TO SAMUEL W.

' GOLDMAN', 0E CLEVELAND, OHIO;

' INSERT'FOR FLOORS, WALLS, AND THE LIKE.

Application filed Kay 27, 1921. Serial No. 473,147.

To all whom it may concern:.

Be it known that I, JOSEPH Hmsusrnm, a citizen of the United States of'America, re.- siding at the city of Cleveland, county of Cuyahoga, State of Ohio, United States of America, have invented a certain new and useful Insert for Floors, Walls, and the like, of which the following is such a full, clear, and exact description as will enable any one skilled in theart to which it appertains to make and use the same, refer ence being had to the accompanying drawings, forming part of this specification.

My invention relates to an insert for use in floors, walls, or ceilings of concrete or.

other materials which are poured or molded in forms, one specific purpose of the insert being to provide means for attaching and supporting gas or liquid pipes from ceilings. Objects of my invention are to provide a one piece insert of economical form and so constructed asto permit ready at tachment and detachment of the supporting members for the pipes or'other devices and having support engaging members in different planes for the-purpose of horizontal and vertical adjustment of the position of the pipes or hangers or compensation for variation in distances between a pipe and the various inserts by means of which it is to be supported.

In the accompanying drawings, Figure 1 is a view in vertical cross section of an insert embodying my invention and showing a pipe hanger supporting member in position in the insert; Figure 2 is a perspective view of one half of the "insert showing the internal ledges on one side for engaging with the head' of the hanger supporting member; Figure 3 is a horizontal section on the line 33of Figure 1; Figure 4 is a bot-' tom plan view; Figure 5 is a vertical cross section of an insert illustrating a modifica:

tion in the shapeof the ledges.

The insert 1 is a hollow member cast in one piece and having at least two and preferably all its outer side walls converging as shown to form an inverted frustum of a pyramid whereby it will be securely held against withdrawal from the concrete or other floor material which is poured around it. The inner walls of the insert are provided with support engaging members in the form of integral palrs of projecting ledges or lugs 4 and 5 and may be provided a longitudinally and vertically extending free space exists in the central portion of the insert for the movement of the body portion of this bolt. The lugs 4 have their upper surfaces in the same planeand the lane of the upper surfaces of the lugs 5 1s abovethat of the lugs 4 and the lugs 5.

are also displaced laterally from the lugs 4.

In other words, the supporting engaging surfaces of these two pairs of lugs are in staggeredrelation being in different horizontal and different vertical planes. The insert has an opening 7 through its bottom wall, a' portion of this opening lying between the lugs '4 and the remainder being wider for the reception of the head 8 of hanger bolt 9. The head of the hanger bolt may thus be introduced into the insert and the bolt then moved to the position shown in dotted lines in Figure 1 if it is desired to support it from the lugs 4 mean he moved vertically upward from this position and then to the position shown in full lines in Figurel if it is to be supported from the lugs 5. In a similar manner the head of the 'bolt can be positioned on the upper surfaces of the lugs 6. It will be-noted that the construction described provides for both vertical and horizontal adjustment of the hanger bolt 9 and thus ready installation of pipes or other devices in a supported position with respect to the insert.

- For convenience in engaging the head of the hanger bolt 9 with the desired lugs on the insert, the forward ends of the lugs may be rounded or downturned as shown in Figure 5, and the upper surfaces curved whereby the hanger bolt is prevented from readily slipping oil? and the bolt may be posiolt 9 and the relationed at any angle to the vertical axis of 'integral nail or staple receiving ears 11, or

with both of these devices. Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. An insert adapted to be positioned in the material of a floor and having portions engaging with said material to hold it against withdrawal therefrom and provided with support engaging members in difierent horizontal planes.

2. An insert adapted to be positioned in the material of a floor and provided with support engaging members in diderent horizontal planes.

3. A device of the class described comprising a hollow member having an opening through one of its walls and support engaging members projecting from its inner surface in different horizontal planes.

4. A device of the class described comprising a hollow member having an opening through one of its walls and support engaging members projecting from its inner surface in diiferent horizontal planes and in staggered relation.

5. A device of the class described comprising a hollow member having an opening through one of its walls, and support engaging members projecting from its inner surface in different planes, said support engaging members being positioned-to leave an unobstructed space in the central portion of the device for the passage of a supporting member from an engaging member in one plane to that in another plane.

.6. A. device of the class described comprising a hollow member having converging outer side walls and having an opening through one of its walls, and support en-- neraaaa gaging members integral with and project ing from its inner surface in diderent planes, said support engaging members beingpositioned to provide an unobstructed space in the central portion of the device for the passage of a supporting member from an engaging member in one plane to that in another plane.

7. A device of the class described comprisin a hollow member having an opening throng one of its walls and two pairs of lugs, the lugs of each pair projecting inwardly from opposite walls of said member, said pairs being in difierent planes, and the support engaging surfaces of each pair being in the same plane.

8. A device of the class described comprising a hollow member having an opening through one of its walls and two pairs of lugs, the lugs of each pair projecting inwardly from opposite walls of said member, saidpairs being in different planes, and the support engaging surface of each pair being in the same plane, the support engaging surface ot-one of said pairs of lugs being laterally displaced from those of the other.

9. An insert adapted to be positioned in the material of a floor and having portions engaging with said material to hold it against withdrawal therefrom and provided with support engaging members in different til!) horizontal planes, said support engaging members having their upper surfaces down turned at the ends.

ln testimony whereof, I have hereunto set w my hand and afixed my seal.

JOSEPH HIRSHSTEIN. [1a. a]
