Application filed October 30, 1919. Serial No. 334,438.

To all whom z'tmay concern:

' Be it known that CORNELIUS CoLnINs, a citizen of the United States, residing at Burlingame, in the county of San Mateo and State of California, has invented new and useful Improvement in Fastening Elements, of which the following is a specification. I

This invention relates to building con struction and particularly pertains to a clip for securing structural members in relation to each other.

At the present timeimodern buildings are being built with false ceilings. These ceilings are hung from the structural work or reinforced concrete floors or other super imposed parts of the building and are principally formed by suspending a plurality of carrying bars in parallel relation to *eac other from supporting wires carried by the floors structure, these bars supporting a plurality of lathing bars upon which metal lath ing is afterwards fastened. It is common practice to tie the two sets of bars together with wires or other flexible fasteners, although this is objectionable, and it is the principal object of the present inventlon to provide a clip for this purpose, whlch may be instantly applied to the carrying bars and which will receive the lathing bars thereafter locking both bars in fixed relation to each other to provide a lattice-like ceiling structure of suflicient strength and rigidity to support the weight of the plastering after metal lathing has been applied thereto.

The present invention contemplates the use of a clip member formed of a single sheet of metal and having permanently arranged lower ledges upon which the carry ing and lathing bars may rest in positions at right angles to each other, being fitted with tangs, by which the bars may be secured to assume proper position and which members may be bent to lock the bars in position.

The invention is illustrated by way of enampl in the accompanying drawings, in which F i 1 is a view in perspective, showingone orni of clip and further indicating in dotted lines the manner in which it is folded.

Fig. 2 is a View in perspective, showing the clip as applied to the carrying bar.

Fig. '7is a fragmentary view in perspective, showing the ceiling construction.

Referring to the drawings and particularly to Fig. 7, it will be seen that a floor structure 10 is formed. This structure may be of reinforced concrete or tiling and-in either instance will provide suitable permanent anchorage for hanging wires 11. These wires are arranged at spaced intervals to each other and are adapted to receive the carrying bars 12. As shown in Fig. 2 a bar of channel section is utilized as a carrying bar, although it will be understood that other forms of rods and beams may be used. In the event that a channel bar is used, it is held with its depth or web vertical and is supported by tying the lower end of the wire 11 around it, as is common practice. When this is done, it will be evident that the various carrying bars are held in substantially spaced relation to each other and are free to swing. A clip 14 is then applied to the carrying bar as is shown in Fig. 2.

- This clip 14 is preferably formed of a single blank indicated in Fig. 4. Here it another form of the will be seen that two rectangular panels 15 and 16 are formed in offset relation to each other. These panels are adapted to be ribbed or folded along the line a, the continuation of this line forming the boundary between the panels 15 and 16. The panel 15 is furthermore split for a distance along the line b while the panel 16 is split from the opposite end along a line 0. The blank so formed is then folded on the line a to dispose the panels at right angles to each other, after which the panel 15 is bent outwardly along line. (Z and the panel 16 on the line e. The portion separated at b is folded outwardly and then upwardly to form a hook-shaped ledge 17. The width of this ledge agrees substantially with the width of the carrying bar, while its upturned portion will prevent outward movement of the bar and hold it in a seated position upon the ledge. The upper end of the panel 15 is folded outwardly at right angles to the body portion of the panel and parallel to the ledge 17. The length of this portion as indicated at 18 is considerably greater than the width of the carrying bar and thus permits the outer end of this flange to be turned downwardly and over the carrying bar 12 to hold it against sidewise movement.

When the clip 14 has been thus applied, it will be seen that the panel 15 will be at right angles to the bar and the panel 16. It will then be possible to position lathing bars 19 beneath the carrying bars 12 at right angles thereto. These lathing bars are usually of the same dimensions andsections as the carr ing bars and are adapted to rest upon a edge 20 formed by the lower terminating end of the panel 16 which is turned outwardly and upwardly along a line e to agree in formation with the ledge 17. The anel 16 has been furthermore bent downwar y along the split 0 to form a fastening tang 21. This tang extends at right angles to the face of the panel 15 and is in proper spaced parallel relation to the ledge 20 to receive lathing bar 19. When the lathing bar has been placed upon the ledge 20 and forced against the panels so that its depths will be vertical, the tang 21 will be struck downwardly to bind the bar in place, after which their prongs 19 may be clinched through the lath.

Reference being had to Fig. 6, it will be seen that a slight variation has been made in the clip to accommodate the carrying and lathin members. In this case panel 15 has been e ongated to provide additional metal for an inturned portion 15'. This will allow the lower ledge 20 to be set at right angles to and beneath the ledge 17. A slit 22 has been made in the ledge member 17 to form a narrow tang 23. This tang may be bent downwardly and alongside of the channel member 19 whenin position upon the ledge 20. It will be understood that the length of the ledge 17 is greater than the width of the channel and that the ledge 20 is in alignment with the rear edges of the portions 17 and 18 so that the width of thechannel will be accommodated and the tang 23 bent down alongside of the channel after it has been seated upon the ledge.

It will be evident from an "examination of the various figures of the drawings, that this clip may be used to accommodate bars of various sectional formations and dimensions and that in all instances the bars will be held with their depths vertical and will be prevented from turning or shearing within the clips. It will further be noted that the clips are fastened upon the bars by a downwardly striking action and that it will be very convenient for the worker to rapidly apply the cli s and secure them without danger of them ecoming loose and as the folded over portions of the clips merely maintain the bars in their vertical imaeae positions without supporting any weight it will be seen that a very strong clip may be provided from thin gage metal as the bars will be held with their de ths vertical and the clips will be substantia ly under tension stresses. Other advantages are seen in the present instances due to the four point clamping action obtained by the up-turned flanges of the ledges 17 and 20 and the down-turned portion of the tan 18 and 21. This will prevent the bars from turn-. ing and will make it possible to use bars of any section without danger of displacement and without the use of tie wires which are at the present time considered essential.

It will thus beseen that the structure here disclosed while decidedly simple-in its construction and cheap in manufacturing costs, yet provides a very desirable connecting mem er for carrying and lathing bars used in ceiling and partition work, insuring that the bars will be held against movement in relation to each other and may be rapidly secured in the position desired.

While I have shown the preferred form of my invention, as used in forming a ceiling structure, it will be understood that various changes in the combination, construction and. arrangement of parts might be made by those skilled in the art, to form partitions and other like structures, without de arting from the spirit of the invention.

aving thus described my invention, what I claim and desire to secure by Letters Patent is 1. In combination with a pair of structural elements adapted to cross each other, at an angle, a clip having connected body panels extendin vertically and against which one side ace of the structural elements may rest in their angular position,

hook-shaped ledges formed at the bottom of said panels adapted to provide a permanent seat for said channel elements and to hold them against the panels and foldable tangs formed at the top of each of said panels and adapted to be struck downwardly over the structural elements to hold them in their intended osition.

2. A b ank from which a clip may be formed to secure structural elements at an angle to each other, said blank comprising a pair of rectangular panel members disposed to form a blank of greater length than either of the panel members and offset relative to each other to producea step like formation at the ends of the blank, said step continuing in slits which extend to points adjacent the transverse center of the blank,

3. A blank from which a clip may be formed to secure structural elements together and at an angle to each other, said blank comprisin a pair of body panel members oif-set in re ation to each other with the top of one panel member in alignment with the bottom of the other panel member, and one edge of one panel member in longitudinal alignment with the opposite edge of the other panel member, all said portions extending from the aligned edges of the panel members, a distance substantially half of the width of the panel members, and substantially half the length of the panel members, and tangs extending oppositely one from the aligned ends of each of the panel members, and parallel thereto.

4:. In combination with a pair of structural elements crossing each other at an angle, a clip having connected body panel members disposed so that one face of each structural element may rest a ainst one of the panels, an L-shaped ledge ormed at the similar ends of each panel adapted to form a permanent seat for said structural elements, and foldable tangs extending therefrom the other end of each panel being adapted to be bent over the structural elements to hold them in their seated positions.

5. A fastening element for holding two intersecting structural members in equal relation to each other, comprising a body portion formed of two panel members bent to conform to the backs of the angularly disposed structural members, a ledge extending outwardly from the face of each of said panels, and providing a support for the structural members, and to prevent lateral movement thereof, and tangs extending outwardly from said body panels and spaced a distance from the ledge substantially equal to the height of the structural elements, said tangs being adapted to be struck over and bent over the sides of the structural members, to hold the same against movement relative to the fastening element.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
