PHILIP HOGAN, OF ST, LOUIS, MISSOURI.

SEAM ANCHOR.

Application led May 2,

T all whom it may concern Be it known that I, PHILIP I-IocnN, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Seam Anchors,

of which the following' is a specification such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the attaching ot conduits, cables, and wiring, etc. to building Walls and consists in an improved seam anchor adapted to be used for such purposes. In Patent No. 1,474,835 issued to me lTovember 20, 1923, I illustrate a scam anchor consisting of `iuxtaposed angular members inserted in a seamr with their inner diverging ends thrust apart to engage the faces of the seam to frictionally engage the same and hold the anchor in place.

The main object of my present invention is to utilize some of the principles of the above-mentioned structure in providing seam anchor elements adapted to be mounted in spaced seams, respectively, and to cooperate in frictionally engaging faces of their respective seams for the mounting of insulators or other line carrying elements.

In the accompanying drawings which il lustrate my invention- Figure 1 is a section through a Wall showing my seam anchor applied thereto.

Figure 2 is a section similar to Figure 1 but illustrating a modification of my invention.

In my preferred structure, 1, 2, 3 and 4 indicate successive bricks in a Wall and 5, 6 and 7 indicate corresponding seams between these bricks. In scams 5 and 7 a small quantity of the mortar normally lling the seam is removed to permit insertion of angular members 8 and 9, respectively, each of Which has its inner end bent at an angle to the body of the member and terminating in an edge adapted to engage one of the seam faces when the member as a Whole is pivoted on the exterior vertex of the angle formed by its bend which rests on the opposite face of the seam.

imembers 8 and 9 are shown with the interior angles of their bends facing in opposite directions and with their outer ends drawn together by means of a bolt 10 and a nut 11, thus providing frictional engagement of the oppesed faces of each seam by the respective ,members and through the 1924. Serial No. 710,664.

means of a single securing member such as the bolt 10.

In Figure 1 I have illustrated insulators 12, mounted upon bolt 10 and it Will be understood that the number of these or similar insulators may be varied to suit dierent requirements and of course the members 8 and 9 may be inserted in adjacent seams or in seams spaced farther apart than the ilH lustrated seams 5 and 7. bviously, mounting elements other than the insulators shoivn may be secured to the bolt or to members 8 and 9 if desired.

In the modification illustrated in Figure 2, the angular members 13 have the interior angles of their bends facing each other, and to secure the members in place, their outer ends are thrust apart by means of nuts 1st on rod 15. In this construction I also show Cotter pins 1G for preventing accidental movement of the members over the ends of rod 15 and a rod similarly provided With cotters could be used in place of the headed bolt 10 and nut 11 to hold the anchor members 8 and 9 in the position shown in Figure 1.

In Figure 2, a Wire 17 is indicated as a cable attaching element and other securing means may be substituted for the insulators 12 shown in Figure 1.

Other devices for moving the outer ends of the angular members relatively to each other may be substituted for the devices illustrated, and other modifications of details of my invention may be made Without departing from the spirit thereof as expressed in my claims.

I claim:

1. Suspension means for cables or the like comprising angular members each adapted to have one end inserted in a respective sea-m in a Wall With the vertex of its angle engaging one face of the seam and said end pointing away from said face, and means engaging the outer ends of both of said members to move said outer ends relatively to each other to turn the members on the vertices of their angles as fulcrums and thrust the inner end of each member against the face of the Wall seam opposite to the face engaged by the angle vertex.

2. Suspension means for cables or the like comprising angular members each adapted to have one end inserted in a respective seam in a Wall with the vertex of its angle engaging one face of .the seam and said end pointing away from said tace, and means engaging the outer ends of both of said members to draw said outer ends toward each other to thrust the inner end oit each member against the tace of the Wall seam opposite to the face engaged by the angle vertex.

3. In combination, bent members each adapted to be inserted in a respective Wall seam with the exterior vertex of the angle of its bend engaging` the tace ot' the seam nearest the other seam and with a part projecting from the seam, and means for drawing the projecting parts of said members toward each other.

4. In combination, members having ends adapted to be inserted in respective wall seams, and means connecting the other ends of said members to hold their inner ends in trictional contact with opposed surfaces ot their respective seams.

5. In combination, members each having an inner end adapted to he inserted in a wall seam extending at an angle to the outer end ot the member7 and means engaging the outer ends oit said members to hod them in position so that their inner ends are thrust into contact with the opposing faces oltl their respective seams.

G. In combination, members having adapted to be inserted in respective ends Wall seams, and each provided with a liulcrum point spaced trom its inserted end on the tace opposite the other member, a bolt connecting the outer ends of said members, and a nut on said bolt t'or drawing said outer ends toward each other thereby turning said inner ends on said fulerum points to thrust the tulcrum point and inner end of each member against opposite faces ol the seam in which it is inserted.

7. A Wall seam anchoring device comprising angular members each adapted to hare one ot its ends and its angular portion inserted in a respective wall seam, and an adjustable connection between said members exteriorly of the Wall tor turning them on their respectively angular portions as p' 'ots to thrust the inserted portion ot each member against opposite seam surfaces.

8. A wall seam anchor device comprising two bars each having a portion bent at an angle to the bar so that the perpendicular distance trom the end ot said portion to the body of the bar is greater than the thickness of the seam into which it is to be inserted, and an adjustable connection between the bodies of said members.

In testimony whereof I hereunto affix my signature this 28th day of April7 1924.
