May 10, 1960 J. K. HOVIND STUD SHOE CLIP Filed May 17, 1956 INVENTOR.

John K. Hovind BY ATTORNEY STUD SHOE our John K. Hovind, Kenmore, N.Y., assignor to National Gypsum Company, Buflalo, N.Y., a corporation of Delaware Application May 17, 1956, Serial No. 585,517

4 Claims. (Cl. 189-35) atetl opening floor channels and downwardly opening ceiling channels.

The present invention is directed principally to th means for attaching such metal studs at the base to elongate, upwardly opening floor channels, although the invention could be adapted also for aflixing the stud top end to ceiling channel, or for afiixing other perpendicularly abutting framing members of the requisite form of structure.

An object of the present invention is to provide a clip, of relatively simple fabrication, capable of very fast application to a floor channel, adjacent a stud bottom end, which clip will firmly hold the stud bottom end in position, relative to the floor channel which is aflixed to the floor.

A further object of the present invention is to provide a stud end clip having inherent means for alfixation to a floor channel, and further, having such means for aflix'ation as will inherently prevent subsequent movement of said stud end relative to the floor channel. 3

still further object of the present invention is to 7 provide a unitary stud shoe clip as described above having means thereon for the reception and permanent positioning of the bottom edge of sheet lath relative to the floor channel and stud.

2 substantially immediately inward of one flange 13 to immediately inward of the opposite flange 13, in accordance with usual metal stud construction. In the present embodiment shown, stud 15 is prefabricated from two'oppositely disposed

angle irons

16, 16 held in properly spaced relation to provide the desired stud width by a sinuous relatively stiff stud-web wire 17 spot-welded therebetween.

Stud 15 is fixed in its vertical position relative to the horizontally disposed floor channel 11 by means of the novel stud shoes 20 constructed in accordance with'and embodying the present invention.

Stud shoes 20 include as the principal element a threesided, stud edge receiving body 21, including two lateral sides 22 and a third or joining front face side 23.

Lateral sides 22 each include a vertical slit 25 extending upward from the base of shoe 20. Slits 25 are formed in sides 22 by an upward cutting of the side material substantially without removal of material, and in the present embodiment the cut is made at the corner of the lateral sides 22 and the front face 23. A second cut 26 is made in each side 22 extending perpendicularly from the top of the aforementioned cut a distance greater than the thickness of flanges 13 of channel '11, preferably in the order of two or more times said thickness. 3

Tabs 30, of generally rectangular form bounded on two sides by the abovesaid two perpendicular cuts in the lateral sides 22, are bent acutely from the plane of sides 22. In accordance with the invention the two tabs 30 are bent in opposite directions from the respective sides 22 and in the preferred form are each bent outwardly from the shoe body 21.

Tabs 30 are bent to an angle such that an aligned groove is formed between tabs 30 and the front face 23 seen from a side view, Fig. 3, the groove being narrower than the thickness of flanges 13 of channel 11. Shoe 20 is slidingly engaged on channel 11 by forced insertion of a flange 13 into the groove formed at slits 25, the forced insertion further bending tabs 30 to open the groove to the flange thickness dimension. The forced insertion, thus, causes tabs 30 to be resiliently urged against the inner face of flange 13 at an acute or biting angle whereby movement of shoe 20 in either lengthwise direction of channel 11 is substantially precluded.

It will be apparent that the above discussed forced insertion of flange 13 into the groove of slits 25 could These and other objects and advantages of the inven- Fig; 1 is an isometric view of an unfinished partition base portion; 1 I

Fig. 2 is a sectional top view of a portion ofthe structure of Fig. 1 taken on line 2-2. p v g Fig. 3 is a side view of the stud shoe clip ofFigs. 1 and 2, all in accordance with the invention.

In the drawings, Fig. '1 includes a floor 10, upon which an elongate, U-shaped, floor channel 11 is disposed and aflixed in accordance .with the. extent and disposition of a wall or partition to be constructed thereabove. Channel 11 includes a relatively wide bottom face 12 and relatively

narrow flanges

13, 13 extending upwardly from each lateral edge of bottom face 12.

Prefabricated metal partition studs 15, of a generally rectangular horizontal section, extend vertically upward from channel 11. The bottoms of studs 15 rest upon bottom face 12 of channel 11 and extend laterally from result in the outward bending of front face 23 rather than the outward bending of tabs 30. To avoid this undesired bending of front face 23, which would distort the general shape of shoe 20 and reduce the effective holding power of tabs 30 against flange 13, a vertically-elongate, outwardly-raised rib 31 is formed on front face 23 extending upward from approximately the bottom edge of front face 23 to substantially above the upper extent of slit 25. Rib 31 stilfens sufliciently the portion of front face 23, throughout which the rib extends, to eliminate bending of the front face so that on insertion of flange 13 in slit 25 only tabs 30 are caused to bend.

I To facilitate the placing of shoe 20 on a flange 13, each tab 30 has an acutely cut-off bottom edge 32 pro+ viding a tapered groove entrance.

Referring to Fig. 3, it will be seen that a major portion of. the slit 25 isof rectangular shape having two vertical parallel edges, whereby a substantial extent of each side of the flange 13 is engaged by the slit edges providing sufficient stability to the clip without need of any additional attachment means on the clip.

The length of horizontal cut 26 and the angle to which tabs 30 are bent outwardly have each been discussed briefly above. In accordance with the invention, it will now be seen that there exists a relationship between this length and this angle if slit 25is made without removal of material, as preferred. To obtain any given groove opening at slits 25, an increase in length of cut 26 will result in a decrease in the required outward acute angle of tab 30. Conversely, shorter cuts 26 require increased acute angles of tabs 30, approaching 90 degrees. Thus, although the tabs would functions in accordance with the invention at angles of about 1 to 89, to provide the necessary stiffness and bite, an angle in the order of 45 has been found highly satisfactory.

A further, additional advantage of the present novel shoe body 21 is susceptibility to being unitarily formed with a lath edge receiving clip 40, such combination with prior stud shoes being relatively impractical, Clip 40 is formed from a prolongation of front face 23 at the bottom thereof. Front face 23 extends downward below the bottom of lateral sides 22 a distance substantially greater than the thickness of channel bottom face 12, whereby the clip bottom 41 may be caused to rest on the floor 10. Clip bottom 41 extends pe pendicularly outward from front face 23, in a direction opposite to the extent of lateral faces 22, and an extent slightly greater than the thickness of a sheet of lath 42 to be held therein. An upwardly extending lath holding clip face 43 extends upward from the outer edge of clip bottom 41, extending angularly inward for resilient grasping of lath 42 with the exception of a short outwardly angled top edge 44.

The application, during construction, of shoe 20 consists generally of the vertical positioning of a stud with the bottom edge properly disposed between flanges 13 of channel 11. One shoe 2!) is applied to each lateral bottom edge of stud 15. Shoe is positioned to enwrap the stud lateral edge, with the inner surface of the shoe front face 23 abutting the outer face of stud 15. Shoe 20 is then slid downward so that flange 15 becomes inserted within the groove formed by the two slits 25. Upon the application of a shoe 20 at each side of stud 15, stud 15 is sufficiently held at the base against any accidental displacement which might normally occur during subsequent operations in the partition construction.

After completion of the framework erection, sheets of lath 42 are applied thereto, the bottom edge of the lowest thereof to terminate intermediate the ends of the shoe, p0r tions of said lateral sides immediately adjacent said slits being deformed obliquely from the planes of their corresponding sides and for an extent sufficient to separate such portions from the corresponding edges of said front side so as to define tabs whereby the flanges of an associated channel may be sandwiched between said'front side and said tabs, said tabs being angled in directions opposite to each other such as to provide substantially only line contact with the flanges of an associated channel to prevent lateral displacement of the shoe with respect to the channel, said body also including a lath edge receiving clip, said clip including a generally horizontal bottom joined to the lower extremity of said front side and extending substantially perpendicularly therefrom in a direction opposite to said lateral sides, said clip also including a face portion extending substantially vertically from said bottom in general parallelism with said front side of the body and in spaced relationship thereto to re.- ceive a lath edge therein.

2. The assembly as defined in and by claim 1 wherein said front side of the body is provided with a vertically extending outwardly-raised rib substantially medially between the opposite sides thereof and extending upwardly from adjacent the bottom edge of said front side to substantially above the upper extent of said slits.

,3. The assembly as defined in and by claim 1 wherein said clip face is provided with an outwardly angled top edge portion to facilitate the reception of a lath, said clip face extending angularly inwardly toward said front side of the body for resilient grasping of a lath therebetween.

4, A shoe for holding an elongate framing member 1 relative to a generally perpendicularly disposed flanged channel, said shoe defining a framing-member-edge-re- .ceiving-body, said body including a front side and two lateral sides extending from the front side along opposite side edges thereof, said lateral sides being joined to said front side along lines extending parallel to each other course being positioned and held thereafter by insertion into clip 40 of shoe 20. I

Shoe 20 may be used also for stud positioning where expanded metal lath is contemplated rather than sheet lath, in which case clip 40 of shoe 20 could be eliminated therefrom. It is further contemplated that shoe 20 could be used in combination with a flanged ceiling channel for positioning stud upper ends.

Having completed a detailed description of the preferred embodiments of my invention so that those skilled in the art may practice the same, I contemplate that other variations may be made without departing from the essence of the invention or the scope of the appended claims. a

What is claimed is:

and there being a flange-receiving slit along thelines of juncture between the lateral sides and the front sides which slits extend from the bottom end of the shoe upwardly thereof to terminate intermediate the ends of the shoe, portions of said lateral sides immediately adjacent said slits being deformed obliquely from the planes of their corresponding sides and for an extent suflicient to separate such portions from the corresponding edges of said front side so as to define tabs whereby the flanges of an associated channel may be sandwiched between said front side and said tabs, said tabs being angled in directions opposite to each other such as to provide substantially only line contact with the flanges of an associated channel to prevent lateral displacement of the shoe with respect to the channel.

1. A shoe for holding an elongate framing member relative to a generally perpendicularly disposed flanged channel, said shoe defining a framing-momber-edge-receivingbody, said body including a front side and two lateral sides extending from the front side along opposite side edges thereof, said lateral sides being joined to said front side along lines extending parallel to each other and there being a flange-receiving slit along the lines of juncture between the lateral sides and the front sides which slits extend from the bottom end of the shoe upwardly References Cited in the file of this patent UNITED STATES PATENTS
