18 Claims.

The invention relates to means for securing floor boards and more particularly wooden floor boards or planks to a supporting structure of the steel beam type.

Anobject of the present invention is to provide 'an improved floor clip for securing floor boards to a supporting beam or sill.

Another object of the invention is to provide a clip which is simple in construction and at the same time provide a clip which effectively secures the floor ,boards to asupporting sill.

Another object of the invention is an improved method of constructing a clip of the above type from a bar of rolled metal stock.

Another object of the invention ls the improved method of constructingl a clip of the above type from predetermined lengths or widths of metal bars-of the desired cross-sectional form which provides for a minimum amount of tooling when fabricating such lengths or widths into their final form.

Another object of the invention is the improved method of constructing a clip of the above type from predetermined lengths or widths of metal bars of the desired cross-sectional form which provides the clip fabricated from such lengths or widths with integral means for locking the nut which clamps the clip in securing position against rotation.

With these and other objects in view, the invention consists of novel details of construction and arrangement of parts as will be more fully` hereinafter disclosed and particularly pointed out in the appended claim's.

For a more complete understanding of the invention reference may be had to the accompanying drawing, in which several forms of the invention are illustrated, and in which:

Fig. 1 is a fragmentary vertical section of a floor construction showing the application of one .of the devices of the invention;

Fig. 2 is a transverse sectional view `oi' the rolled metal bar from which one form of the device of the invention is fabricated;

The present reissue application is one of two applications covering the subject-matter of the original patent, and this `application relates particularly to the preferred embodiment of Figs. 1 to 6 oi said patent and to the method of making 9, 1931. Application December 16, 1940,

(ci. zii-14s) iioork clips. The co-pending application, Serial No. 370,429, filed December 16, 1940, relates to the subjects-matter of Figs. 7 to 15, inclusive, of the original patent.

Referring now to the drawing, and particul larly to Figs. 1 to 6, inclusive, in which one form of the invention is illustrated, the reference character rv2 indicates the side sill of a railway car, and'which extends longitudinally thereof, and usually comprises an I beam or a U beam having a horizontally disposed upper sill flange 3. The sill 2 is adapted to support the floor -boards extending across the car, one of which is indicated by the reference character 4 and secured kthereto by means of a clip indicated generally by the reference character 5. The clip 5 is fabricated from a predetermined length of a rolled metal bar 6 of the form illustrated in transverse section in Fig. 2 and consists of Ya. main body portion 1 of rectangular cross-section and. a narrow integrally formed rib formation 8 extending laterally from a side of the same.

' The clip 5 is fabricated from a predetermined length of the bar 6 by means of a suitable shearing and forming operation to provide the same with a frame engaging iiange in the form of an offset portion 9 at one end thereof to position this portieri 9 out of the plane of the body of the clip and at the proper angle so as to conform to the angle of the lower face of the sill iiange 3 while the horizontal body of, the clip 5 or attaching flange bears against the underside of the board 4. A toothed or prong formation l0 is formed at the forward end of the body of the clipl bolt opening l2 in the clip and on a line of sevy era'nce' sufficiently spaced from said opening or aperture to leavel a substantial unbroken reinforcing area between said line and said aperture. This sheared portion forms a wing member I3 having its freeend in the general shape of a `tongue arcuately formed and directed downv wardly and provides means for locking the nut which secures the clip inI fastening position against rotation,l as will presently be described.

As illustrated in Fig. 1, the board 4 is provided with a bolt hole 20 adjacent the edge of the sill board I to the sill 2 against movement. 'Ihe clip 5 as provided'wlth the bolt opening l2 for the passage of the-bolt 2i may now be placed on the same and positioned to permit the angularly disposed offset 9 to contact the lower face of the sill flange 3. A nut 22 may now be threaded on the bolt 2I and threaded home to force the tooth or prong I into the-'underside of the board I and place the horizontal body of the clip in firm contact with the underside of the board 4 and in the plane of the upper face of the sill 2 which includes the sill flange 3. The wing I3 may now be bent down by engaging the downwardly directed forward portion of'the same by a suitable tool from its position indicated in dotted lines in Fig. 1 to its locking position. When in locking position the wing I3 lies adjacent one side of the nut 22 as clearly illustrated in Pig. 1 and prevents rotation of same 5 the board 4 is firmly upper face of the sill 2, I0 thus embedded in the in turn. prevents rotation held in contact with the underside of the board 4 of the clip when in fasand by the use of the clip flange 3 and is adapted to receive the bolt 2I which extends therethrough. This bolt 2I in combination with the clip 5 secures the iloor cover all such changes as come'wlthln the spirit and scope of the appended claims.

The invention is claimed as follows:

l. The method of making a fastening clip which consists in shearing a blank of predetermined length from al metal bar having. a rectangular cross-section and a laterally extending rib and simultaneously forming said blank to proand the tooth or prong tening position. 'I'he wing I3 integral with the clip provides locking means for the nut 22 and prevents the same from working loose by reason of the fact that the wing I3 forms an integral part of the clip 5` and lies in close proximity to a face of the nut 22.

One of the most important characteristics of the floor 'clips embodying the preferred embodiment of the invention lies in the fact that the bolt locking members are so constructed that they are readily bendable in such a direction as to move into nut locking position, but these nut locking members are also adapted to withstand the turning movement of the nut with a maxlmum resistance.

Thus the nut locking flange I3 is made of such cross section, particularly at the 'point of bending, preferably only a small fraction of the cross section of the body of the clip taken on a transverse line at the base of the locking flange, that it can readily be bent downward from the dotted line position of Fig. l tothe full line position because the bending takes place away from the face of the floor clip. and the nut locking flange is relatively thin at the point where the bending takes place. t

The nut locking flange is, however, adapted to resist turning of the nut 22 by the edgewise engagement of the flange I3 and any bending of the flange in that direction would be transverse to the direction of bending of the nut locking flange which takes place during the-movement from the dotted line position of Fig. 1 to the full line position. Thus the cross section of the nut locking flange is suitably weakened to facilitate the bending in such direction as to bring the flange into nut locking engagement with the nut, but its strength and rigidity are maintained in a transverse direction to resist turning of the nut.

While there has been illustrated and described the iloor clip and its various modifications associated with a floor construction applicable to a railway car, it ls to be understood that they are applicable for use in securing the boards of a floor in various constructions. Neither should the invention be limited to the exact structures as shown. vas changes and modifications will `readily suggest themselves, and it is desired to l integral section attached thickness into position to vide the clip with a. downwardly directed rib por-tion and upwardly extending prong and an offset portion angularly displaced with relation to the body of the clip.

2. 'I'he method of making a. fastening clip which consists in shearing a blank of predetermined length from a metal bar having abody of rectangular cross-sectionand a laterally extending rib and simultaneously shearing and forming said blank to provide the clip with a downwardly directed tongue comprising a portion of said rib and an upwardly extending prong comprising the oppositely biased end of the section'.

3; The method of making a fastening clip which consists in shearing a blank of predetermined length from a metal bar having a body of rectangular cross-section and a laterally extending rib and then simultaneously shearing and forming said blank to provide the clip with a downwardly directed tongue comprising a portion of said rib, an formed of the oppositely biased end of the section and an offset portion angularly displaced with relation to the body of the clip.
