v Our invention relates to an improvement in a bracketing device, the brackets being mounted singly or in series. The purpose of the bracket is toV` hold elements in alignment with a definite channel or course.
Our invention pertains to a sheet metal surface having a keyway therein and inserting in said keyway a bracket having a base portion which fits into the keyway and is locked into position by pressure of anges on the base. The bracket arms extend outwardly from this base and outwardly from the keyway.
In the construction field particular facing plates are often used to maintain various construction materials in position. At times it is desirable to place dowels through these materials and facing plates, and unless the ends of the dowels are held in position there is danger when placing other materials about these facing plates that these dowels may become displaced, vand it is for this purpose that these brackets, whichl otherwise might be stamped out of the facing plates, are made as separate and individualunits and pressed into position wherever they may be desirable, thus making it convenient to shape the facing plates flatwise and the brackets separately. The brackets can be fitted into place on the job. While these brackets and facing plates may operate most effectively in the construction eld we do not Wish to be limited to this field.
Referring to the drawing:
Figure 1 is a perspective view of the present invention,
Figure 2 is a vertical sectional view along line 2--2 of Figure l1,
Figure V3 is a front elevation of the bracket,
Figure 4 is a horizontal sectional view of an vassembly embodying opposed brackets, and,
Figure 5 is a vertical sectional view corresponding to Figure 2 of a different embodiment of the invention.
Figure 1 shows a type of construction material I0 having a facing plate II on either side. This facing plate II has a keyway I2 stampedtherein, the shape of the keyway'being apparent` from thecross-sectional View. The bracket portion I3 nts into the depressed keyed edges I4 and is rmly held in position by the flanges I5. These anges are shaped the same as the keyway edges I4 and with just sufcient spring to make it necessary to use force to press the base I3 of the bracket into position between the keyway ridges I4. From the base I3 of the bracket extend two arms I6.
This product may be utilized as a supporting bracket, so to speak, by imbedding the arms I6 into a cementitious block or substance and using the base I3 of the bracket as a supporting means, or the base of the bracket may be the seat of the bracket and the arms used for suspending various materials thereon, or modifications may be made in thesevarms for various purposes.
Figure 2 shows a sectional view of the bracket in which the base I3 is pressed into the facing 10 keyway I2. This view also shows the locking ridges I4 and the base portion I3; together with the flanges I5 pressed therein. The extension represents the arm or arms of the bracket.
Figure 3 shows the bracket in detail, in which 15 I3 represents the base of the bracket, I5 the outwardly projecting flanges for interlocking in the keyway ridges I4, and the projecting arms i6 each having a turned ange I'I, which turned flange has an opening I8 therein to receive dowel 20 supports `and an opening I9 for the receiving of a rivet or other fastening means in drawing oppositely aligned brackets together. It will be noted that the arms I6 `project from the base section I3 directly from the edges 2U and inde- 2 5 pendent from flanges I5, which project outwardly and are the locking means of the bracket between the rigid keyways I4. When the bracket in Figure 3 is pressed into position, as in Figure 1, the shape of the base of the bracket will hold 30 it firmly lin 'position without the possibility of sagging the bracket by pressing on either arm.
It can further be held in position by a rive-t through the opening I9 in Figure 3 extending through opposite keyways and opposite brackets 35 so that the two bases of the respective brackets can be' drawn up together with the facings into one comprehensive whole.y Openings 22 in the foundation plate I!! are shown in Figure 4, the openings 'I3 being adapted to receive dowel bars` 40 ZI which penetrate through ythe material and the apertures I8 thereby to hold the dowel bar firmly in position without danger of tilting.
It can readily be understood that the bracket may operate from the extension arms and sup` 45 port a facing plate with a keyway, or the ends of the arms vmay support a device extending through the facing plate and lateral extensions of 'the arms. This device may extend through to an opposite bracket on the other side, thus 50 holding this bar or device in a fixed position while other materials may be placed about it, depending upon the purpose for which the bracket and facing plate are to be used.
Likewise, these brackets may be mounted in series along a facing plate in a continuous keyway, or they may be oppositely mounted or staggered, depending upon the purpose for which they are to be used. Likewise, they can be employed without any bar or rod arrangement and used merely for the purpose of holding one surface against another surface, or in spaced relation from that other surface, or it may be desirable to use these brackets in connection with bars, which would slip through the openings at I8, penetrate the opposite face and be anchored at the end of the extension arms in an opposing face .as shown in Figure 4. undoubtedly these facing plates would be utilized in numerous ways for the support of dowel bars.
The keyway likewise need not necessarilybe depressed but a ridge may be outwardly crimped so that it would not be necessary to indent the material housed between the facing plates. Such a construction is shown in Fig. 5 wherein 3D indicates ridges in the foundation support I0 on which are crimped the anges 35 on the` base 33 from which extend the arms 35.
Likewise the bracket may be inserted in a concrete facing or lany kind of monolithic facing', or the keyway may be impressed into any sort of surface and the bracket locked therein in some manner, in which case the facing plate with the keywaywould be eliminated and the keyway. Iimpressed either into the monolithic structure or into any structural material which may be solid enough to hold the bracket.
This bracket and keyway facing maybe made of metal, wood, any composition or otherV material, and likewise, the building element may be composed of any type of material which may by them.
be acceptable forits use. The bracket may be prepared from sheet metal or any of the metals, whether sheet, cast or Wrought, or out of any other composition as long as they can be shaped and accomplish the locking feature with the keyway intended. y
