SEAM CLAMP.

Application filed April 4,

My invention relates to the suspension or carrying of cables, conduits and the like upon the sides of brick or other masonry walls and consists in a spring memberadapted to be inserted in a wall seam and there distorted and held by friction. Such devices are commonly known to the trade as seam anchors or clamps.

The main object of my invention is to provide a simple in Xpensive member adapted to be inserted easily in a seam ina wall and to securely hold a cable or the like against the wall.

An additional object of my invention is to provide means cooperating with such a clamp for attaching individual lines or smaller cables without affecting the design or use of the main clamp member.

In the accompanying drawings which illustrate my invention Figure 1 is a side elevation of a clamp applied to a wall and before the cable is inserted therein.

Figure 2 is a similar elevation of the clamp holding a cable and also illustrates the additional wire carrying member.

Figure 3 is a front elevation of the parts illustrated in Figure 2.

Figure 4 illustrates a modified construction.

Figure 5 illustrates the supplementary element applied to the clamp shown in Figure l.

In Figure 1, A and B represent two bricks, the space C between which is nor mally filled with mortar which is removed at intervals for the reception of the seam clamp. The clamp is preferably formed of a single strip of material possessing some springiness and is C-shaped having a portion adapted to be inserted in the seam C, the end 1 of which portion engages the upper face of the seam and the curved part 2 of the inserted portion engages the lower face of the seam. The opposite end 1 of the clamp terminates adjacent to the out-er face of the wall and ata point spaced vertically from the seam. It will be understood that the clamp is distorted when in the position illustrated in Figure l and that the tendency of the clamp is to press the upper end 1 against the outer face of the wall. When acable D is inserted between the outer end of the clamp and the wall, the clamp is further distorted and whether in the position shown in Figure 1 or in the position shown 1924.. Serial No. 704,293.

in Figure 2., it'will be seen that there is ab threepoint frictional contact between the clamp and the wall provided by the shape and elast-icnat-ure of the clamp.

In the preferred embodiment of my invention the clamp is formed of a flat strap, a portion of the metal of which is displaced as indicated to provide a slot 4 and a flange 3. This construction permits, the insertion of a screw driver E or similar tool as shown in Figure 1 for the purpose of bending the clamp outwardlyv to permit the insertion of the cable D.

The supplementary elementconsists in a holding elements and securely retains thewire F in place.

In Figure 4: I illustrate a modified construction in which the anchor consists in a piece of wire 9 of spring material, the upper end of which terminates in a return bend 10 adapted to be engaged by the screw-driver or other tool as shown to move the upper portion of the clamp away from the wall and permit the insertion of the cable.

The supplementary member 11 to be applied to clamp 9 may be either flat or round and its upper end is adapted to engage the upper end of clamp 9. If member 11 is flat, its upper end maybe slotted or, if round, the upper end may be flattened and perforated, or it may form a coil to surround the clamp.

Various other modifications of my invention may be made without departing from the spirit of my invention as expressed in the appended claims.

I claim: I

1. A. cable or like support for insertion in a wall seam comprising a C-shaped strap of spring material, the distortion of a portion of which frictionally holds the strap in a wall seam, said strap being provided with a tool receiving slot spaced from its ends, and a tool fulcrum element adjacent said slot.

2. A cable or like support for insertion in '70 lighter strip 5, also of springmaterial, and

a wall seam comprising a strap of spring material adapted when distorted to provide spaced points for frictionally engaging. a wall surface and a wall seam surface at an angle to each other, a portion of said strap being displaced to provide an opening through which a tool may be inserted and to provide arfulcrumron which said tool may be pivoted to distort said strap.

a 3. A cable or like support for insertion in a wall seam comprising a strap of spring materialadapted' whendistorted to provide three points, for frictionally-engaging a wall and wall seam surfaces which surfaces are at an angle to each other, and perforated between its ends andprovided with an integral lug adjacent its perforation to permit inser tion of a tool and provide a fulcrum therefor for further distortion to receive a cable or the like between the strap and the wall. 7

4. In a cable or like support for insertion in a wall seam, a spring having one end for insertion in the seam to be frictionally retained therein and having a perforated projection at a point spaced from said end, and an element having an end for insertion in the seam and retained by one face thereof and having its other end adapted to engage said perforated projection whereby said element is distorted. so as to be held in assembly with said sprin .7 5..In an article of the class described, a spring member having a portion for frictionally engaging opposing sides of a wall seam and having a body projecting from said portion to engage the exterior face of the wall, and an element below said member one end of which element is adapted to be inserted in said seam and be retained by said member portionand a face of the wall seam, and the other end of which element is adaptedto be interengaged with the body of said member whereby said element is so as to be held in position.

'In testimony whereof I hereunto affix my signature this 1st day of April, 1924.

PHILIP HOGAN.
