Edward W. Kress, San Jose, Calif. Application February 7, 1940, Serial No. 317,692 3 Claims. ,(cl. 20- 92) The present invention relates particularly to means for preventing relative movement between two angularly joined members, particularly in braces extending from the plate to the sill, and.

each brace being bevelled at its ends to seat solidly against the opposing faces of the studs between which it is placed.

Braces of the type above indicated are, in effect, struts, and when the frame is subjected to unusual stresses and strains in storms and earthquakes they are caused to slip on the surfaces which they contact. This slippage may be slight in any one instance, but more or less constant repetition of the action increases the loosening and slipping of the braces. In the case of a severe earthquake the holding. nails may be pulled and the complete, or practically complete, separation of the braces and studs be effected.

In an attempt to overcome this difficulty it is the practice in some localities to nail a block of wood to each stud in a position to contact the lower end of the brace thereon to prevent its slipping when subjected to the treatment above outlined. But this is only a partial cure for the trouble, merely offering an opportunity to increase the number of upporting nails which will themselves give under a determined thrust from the brace above.

It is, therefore, one object of my invention to provide a device that may be quickly and easily applied to one member in such a manner as to effectually support against slippage a brace or strut seated thereon and against the said memher.

It is another object of the invention to provide a device of the character indicated that will reduce the number of nails required to hold the strut or brace in position, and that can be quickly and easily applied by unskilled labor.

Finally, it is an object of the invention to provide a device for the purpose indicated that will be economical to manufacture, simple in form and construction, small and compact in form, and highly efiicient in its practical application.

In the drawing:

Figure 1 is a perspective illustration showing one form of the device embodying my invention as it appears before placingin position.

Figures 2, 3, 4 and 5, each shows an edge elevation' of the device as applied to different ar rangements of braces or struts.

As herein disclosed the device comprises a piece of sheet metal of any suitable width, preferably that of the brace in conjunction with which it is to be used, and indicated generally at i. This piece of sheet metal is bent back upon itself at one end to form a section of substantial length and of double thickness as shown-at 2, the edge of the bent-back portion being serrate in form as indicated at 3.

Backwardly a little way from the serrate edge 3 the body member I is bent again to form. an apron 4 lying in a plane normal to the plane of the part 2.

The parts 2 and 3 are provided with holes 5 to receive nails as 5.

In Figure 2 is shown a portion of a stud at l, and at 3 to the toe of a brace seated against the stud. When the present device is used as hereinafter described it is only necessary to tack the brace in position before the device is applied, this permitting placing the device snugly against the extreme edge of the toe and preventing any possible movement thereof, and since the device is a perfect support for the brace no customary thorough nailing is required. With the brace in position a saw kerf 9 is made crosswise of the stud and parallel with the toe of the brace and contiguous to it extreme end, or the saw cut may even remove some of the extreme end of the brace. The projecting serrated edge of the device is now inserted in the saw kerf 9 and seated firmly therein, and the apron 4 nailed to the stud, only one or two nails being required. A blow of a hammer will now seat the part 2 against the brace B, and this part is secured by means of a couple of nails as shown. By bending the part 2 in the direction indicated by arrow ID the bend is effected at II at the surface of the stud and the extremity of the brace. The device now cooperates with the stud to form a solid immovable stirrup for the lower end of the brace.

In Figure 3 it is shown that the device may be applied to the upper end of a brace in a similar manner, the part 2 being bent downwardly to seat on the brace as indicated by arrow l2.

In Figure 4 it is shown that a saddle may be made by reversing the position of the device, placing the part 4 between the principal members l3 and M of a truss and bending the part 2 over to seat against the toe of the thrust member l3 as indicated at Hi.

In Figure 5 it is shown that the device may be set in the corner formed by two members, as a stud and plate of a frame building shown in part at I6 and H, to form a seat for the upper end of brace 8 and prevent displacement of the stud relative to the plate if a force acting in the direction I8 is applied to the brace 8.

While the edge of the device entering the kerf 9 is shown and referred to as a serrate edge, it may be made straight or in any other desired form without change in the function performed. In Figure 5 the device is provided with a straight edge at IS.

The device may also be effective applied without the formation of the kerf 9. In applying it in this manner the serrated edge is merely driven into the stud at the desired point. However, in setting the device in this manner it is desirable that the part 2 be further strengthened so that it will not collapse under the pounding to which it will be subjected. I accomplish this by stamping ridges as at 20 in the part 2 in parallel relation to the side edges of the part. Since the ridges extend from the forward to the rear edge of the double part 2 they make that part as rigid as a nail, and permit the teeth to be driven into the wood in the same manner.

It will be noted that the part 2 may be bent toward or away from part 4, or left in its original position relative thereto as circumstances may dictate.

Although certain specific embodiments of the invention have been herein illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated in the accompanying claims.

I claim:

1. A thrust clip, comprising a flexible sheet metal member doubled upon itself at one end to form a rigid two ply body portion, the free end of one of the plies of said body portion being sharp and adapted to be driven into a support to anchor said clip, the free end of the other ply being hingedly connected to said body portion inwardly of the free end of said first ply, each of said plies of said body portion having a plurality of corrugations extending from points adjacent the sharp free end to the line of fold. of said body portion, and said body portion and said hingedly connected ply having apertures therein for securing elements.

2. In a frame building, the combination with a thrust resisting member and a thrust member bearing thereagainst at an acute angle, of a thrust clip having a portion embedded in the thrust resisting member at a point contiguous to the extremity of the thrust member, said clip having a second portion having a bend therein and seating against the outer surface of said thrust member to form a seat therefor, said clip having a third portion having a bend therein and seating against the thrust resisting member, and means rigidly securing said second and third portions to said thrust and thrust resisting members respectively.

3. In a frame building, the combination with a thrust resisting member and a thrust member bearing thereagainst, at an acute angle, of a thrust clip having a two ply body portion, a free end of one ply being embedded in said thrust resisting member at a point contiguous with the extremity of said thrust member, the adjacent free end of the other ply having a bend therein and seating against the thrust resisting member, means rigidly securing said last named free end to said thrust resisting member, said two ply body portion having a bend therein and seating against the outer surface of said thrust member, and means rigidly securing said body portion to said thrust member.

EDWARD W. KRESS.
