7 Claims. (01. 293-55) This invention relates to supplemental bumper bar protecting means and more particularly to improved means for securingsupplemental guard rails or bars tovertical guards.

Ihe principal'object of this invention is to provide improved means wholly supported by two or more horizontally extending guard rails for securing the rails in position on a vertical guard. i i 1 Another object of this invention is to provide wedging means wholly supported by a pair of guard rails for spreading said guard rails against the edges of seats in a vertical guard.

Another object of this invent-ion is to provide such wedge means in the form of a pair of opposed wedges wholly supported by the supplemental guard rails.

Other objects of the invention will appear from the following description taken in connection with the drawings, in which Fig. 1 is a front elevational viewof a vertical guard provided with supplemental guard rails or bars; i

Fig. 2 is a vertical section on the line 2-2 of Fig. 1, showing one form of my improved securing means; i

Fig. 3 isa horizontal section on the line 3-3 of Fig. 2;

Fig. 4 is a vertical section corresponding to Fig. 2, of another form of securing means;

Fig. 5 is a vertical section taken on the line 5-5 of Fig. 4; i i r n Fig. 6 is a vertical section corresponding to Fig. 4, showing a third form of my improved securing means; I

Fig. 7 is a vertical section corresponding to Fig. l, showing a fourth form of securing means used in connection with three guard rails;

Fig. 3 is a front elevational view of Fig. 7; and

Fig. 9 is a vertical sectional view corresponding to Fig. 4, showing a fifth form of securing means.

For purposes of disclosure, I have illustrated in Figs, 1 and 2 a horizontally extending bumper bar II] which may be of any shape horizontally and vertically, against the front face of which may be seated rearwardly extending flanges ll of a vertical guard [2 which may be secured to the bumper bar by means of a clamping plate l3 drawn toward the vertical guard by bolts l4 and nuts as shown in Fig. 2. For the purposes of disclosure, I have shown supplemental guard rails or bars l6 and I1, Fig. 2, connected to a single vertical guard l2 but it is to be understood that these guard rails may be made longer and may be secured to two or more vertical guards by my improved securing means hereinafter described, which holds the guard rails against horizontal movement relative to the vertical guards and permits of an adjustment between the guard rails and the vertical guards. I have disclosed several forms of securing means which may be referred to as of a floating type in that they are wholly supported by the guard railsand have no connection with the vertical guard.

In Figs. 2 and 3 I have disclosed one form which comprises an inner wedge-shaped spreading member 20 which may be of channel shape as shown and an outer straight member 2| which may also be of channel shape as shown. These members may be connected by a bolt 22 anchored in the inner member 20 and extending through an aperture in the outer member 2!, a nut 23 on the bolt constituting the means by which the members are drawn toward each other. When the nut is screwed upon the bolt, the wedgeshaped ends of the flanges on the inner member 20 force the guard rails l6 and H apart into tight frictional engagement with the edges of the apertures in the flanges of the vertical guard.

In Fig. 5 I have shown another form of wedging spreading means comprising an inner wedgeshaped channel member 25 to which is anchored a bolt 26, extending through an aperture in an outer wedge-shaped channel member 21, a nut 28 on the bolt serving to draw the members toward each other and spread and force

flat bars

29 and 30 into frictional engagement with the edges of apertures in the vertical guard.

The securing means shown in Fig. 6 comprises an inner wedge-shaped spreading channel member 32 to which is anchored a bolt 33 extending through an aperture in an outer member 34 which may also be of channel shape, the walls of which may be cut away to provide seats 35 bearing against the ends of the legs of U-shaped bars 3B, the portions of the flanges between the seats spacing the bars, and being connected to the seats by curved surfaces which operate to spread and position the bars.

In Figs. 7 and 8 I have shown securing means for securing three horizontally extending guard rails on a vertical guard which comprises an inner channel member provided with a central notch to receive the center bar 4| and with end wedge faces to engage and spread the

outer bars

42 and 43 which may as shown he of substantially rectangular cross section. Anchored in the plate 40 are tightening

bolts

44 and 45 which extend through apertures in an outer channel member 46 of the same construction as that of the inner member 4!],

nuts

41 and 48 being provided for the purpose of drawing these members together.

The securing means shown in Fig. 9 consists of an outer channel member 50 through which extend the shanks of a U-shaped bolt 49 embracing the center bar 5|, the ends of the outer member bearing against the rear edges of the legs of

outer bars

52 and 53.

Nuts

54 and 55 are threaded on the shanks of the U-shaped bolt to draw the same to the rear and to force the outer member 50 toward the front to force the rear edges of 'the'center bar 5| against the rear edgesof the center apertures in the vertical guard a'rid to f orce the front faces of the outer bars 52 and'53 against the front edges of the outer apertures in the vertical guard. These bars maybe of U-shap'e cross section as disclosed in Fig. 6 or they may be of any other desired cross section.

While the invention has been described in con nection with the illustration of several modifications, it is to be understood that the invention may take other forms and that applicant reserves the right to such forms as fall within the principle of this invention and the scope of the appended claims.

I claim: Y Y

1. The combination with a vertical guard adapted to be mounted on a horizontal bumper bar and provided with transversely extending apertures at a higher levelthan the bumper bar to receive a pair of Vertically spaced horizontally extending bars, bars extending through said apertures, and securing means carried by and operating on said bars to force said bars in onposite directions against the edges of said apertures.

2. The combination with a vertical guard adapted to be mounted on a horizontal bumper bar and provided with transversely extending apertures at a higher level than the bumper bar to receive a pair of vertically spaced horizontally extending bars, bars extending through said apertures, and securing means carried by and operating on said bars and including a wedge-shaped element to force said bars in opposite directions against the edges of said apertures.

3. The combination with a vertical guard adapted to be mounted on a horizontal bumperapertures, and securing means carried by and operating on said bars and including a wedge tures, and securing means comprising wedgeshaped members located on opposite sides of said bar-s together with means for drawing said members toward each other.

5. The combination with a vertical guard adapted to be mounted on a horizontal bumper bar and provided with three transversely extendirig apertures at a higher level than the bumper bar tojreceive three vertically spaced horizontally extending bars, bars extending through said apertures, means for securing said bars to said vertical guard comprising opposed members of the same construction each provided with a central notch and with Wedge-shaped end faces cooperating respectivelywith the center bar and the outside bars and means for drawing said members toward each other.

6.
