SEAM ANCHOR.

Application ined March 1s, 1922. serian No. 544,858.

, To all whom it may concern L' Be it known that I, PHILIP I-IoGAN, a citi zen of the United States, residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Seam Anchors, of which the follow-ing is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this application.

My invention comprises an anchor for cables, pipes, brackets, insulators, etc., adapted topbe inserted in theseam of a wall of masonry, and the objects of my invention are tof provide a simple economical device adapted to be easily inserted Vand to be securely retained in the seam after insertion, and to provide a substantial support for whatever wire or other object is to be carried thereby.

In the accompanying drawings, which illustrate several embodiments of my invention,-

Figure 1 shows a simple form of my anchor as it is being inserted in the wall seam.

Figure 2 shows the same anchor mounting and insulator and clamped in wall-engaging position.

Figures 3, 4, 5 and 6 show obvious modifi cations of the anchor, which will be referred to later.

The essential feature of my invention `is the provision of an anchor element adapted to be inserted in the seam and then turned about a pivotal point so as to cause a toothlike projection upon the element to bite into the wall of the seam, means being provided to hold the bar in the desired position.

In the construction shown in Figures 1 and 2, these elements are duplicate flat bars 1 and 2, having their adjacent ends 3 and 4 inclined outwardly and when inserted in the seam, as shown in Figure l, the corners of the bends 5 and 6 serve as fulcrums about which the bars may be pivoted by forcing their outer straight `ends 7 and 8 together, thereby thrusting the edges 9 into the adjoining bricks A and B. The outer ends of the bars are clamped in the desired position by means of a bolt 10 and in the preferred construction this bolt also mounts a porcelain insulator 11.

It will likely be found desirable to drive `a small Awooden plug 12 between the lower Y and a short screw 14 is substituted for the f bolt 10y of Figure 2.

' In Figure l a similar bar 15 is used but is inserted far enough into the seam to bring the end of its return bend againstthe side of the brick. In this ligure, the upper bar only has its inner end inclined and is forced into engagement with the brick by the insertion of a straight `bar 16, the original shape of bar 15 being'indicated by the dotted lines.

In Figures 5 and 6, two other modifications o'f the wire or cable holding bar are shown, the particular advantages of which will be obvious to those skilled in the art. The peculiar shapes of the outer ends of the upper bar 17 of Figure 5 adapts it tor holding various devices and this. end may possess a substantial degree of elasticity. The lower bar 18 of Figure 6 is provided with a linger 19 which will lit over the body of upper bar 20 and clamp the two together. These two .bars may be swiveled horizontally to engage the body of the upper bar with the finger or the latter may be made straight and bent over after assembly.

Other variations in the construction of my anchor will occur to those familiar with such devices and I contemplate all such modifications as tall within the spirit of the appended claims.

What I claim is:

1. A seam anchor comprising two bars each having an end portion bent obtusely to the remainder of the bar, said bars being arranged back to back with their bent portions extending away from each other and with the external angles of their bends forming a pivotal bearing for the bars, the

ot the bends.

2. A seam anchor comprising juxtaposed bars each having a portion bent at an angle near one end, said bent portions diverging from each other,v and means for drawing said bars together at a point spaced from said projections.

3. In a seam anchor, two juxtaposed members having adjacent ends extending from axis oi which is perpendicular to the plane the planes of the bar bodies in diverging directions and adapted to be inserted in a wall seam, and means for drawing the bodies ot the members together to force the inclined ends apart and engage the sides of the seam.

LL. In a seam anchor, two juxtaposed members having their adjacent ends inclined in diverg'ing directions out of the plane of the member bodies and adapted to be inserted in a wall seam, an insulator positioned on the bodies of said members, and an element securing said insulator to said members and securing the bodies of said members together thereby pivoting the members on each other intermediate their ends to thrust their diverging ends apart to engage the sides of the wall seam.

5. A seam anchor composed of two superimposed members having their respective ends juxtaposed and diverging from each other but adapted to be inserted in the seam between two bricks and means for drawing together the ends of the members remaining outside of the seam, thereby pivoting the bars on each other intermediate their ends to thrust their inserted ends apart.

6. A sea-1n anchor composed of two superimposed members having their adjacent ends iianged in opposite directions and adapted to be inserted in the seam between two bricks so that when the other or outer ends of the two members are drawn together the flanged ends will be sepa-rated so as to bite into the bricks, and an insulator mounted on the top member et the anchor.

7. A seam anchor comprising two juxtaposed members, two adjacent ends of which diverge from each other and are adapted to be inserted in ya wall seam, and a bolt extending transversely through the opposite ends of the members to draw the bolted ends together and thereby spread apart the firstmentioned hanged ends.

8. A seam anchor compnising jnxtaljiosed bars, at least one ot which is bent at an angle near one end, and means Yfor drawing the other end of said bent bar toward the adjucent portion of the other bar, thereby turning said bent bar about the vertex oit the angle of its bend as a pivot.

In testimony whereof I hereunto aiix my signature this 14th day of March, 1922.

PHILIP HOGAN.
