i I i This invention relates to a Yclamp andmore multiple platel clamp, the several plates of which are combined-to produce an attractive design.'v A further object is togproduce a clamp'plat'e having a :recessedfsurface of ir-V regularand/or-nar'row design which can be convenientlyA polished orl otherwise prepared for ilse. AAnother object is to provide a clamp for' holdingthe bars of a bumper in properfspaced relation and such a clamp whichmay be easily and quickly'apphed to the bars. Y f' -Further and more yor less limited objects will be apparent from the drawings, the followingy description' and the use of articles coveredby'the appended claims.

-In thedrawings Figil represents a fractional front elevation of a pair lof bumper bars, showing a clamp embodying my invention attached thereto; Fig; 2v shows a plan view of the rassembly shown in Fig. 1; Fig.v 3is a sectional view taken on a vertical line through the center of the clamp shown in Fig. l; Fig. 4 is a view similar to Fig. 3 with Y the plates of the clamp separated from each other and from the bars.

In the following description I shall refer to the impact surface of the 'bumper as the front surface and the terms front7 and rear7 will be used in view Of'such assumption. `It is not, however, thereby intended that the Vuse of the clamp be limited to any l particular position on the bumper or in relation to the vehicle. y

Of the reference characters l and 2 denote vertically spaced impact bars of a bumper, having suitable front surfaces which are here shown as grooved. The numeral 3 indicates Y support bars and having surfaces adapted to bear upon the adjacent edges of the said bars. Thefront surface offthe 4clamp l Sis shown as having afrfaised edge 5 which may be of any configuration to give the 'Iney i, 'I v` chanical and orna'mental4 effect desired.` .This raised edge is herein yshown as extending around thelouter edge of the plate,leaving a recessed ordepressed surface 5a Vwithin the raised edge'. 1 The outer-.plate 6r has a rear-` surface. 7 adapted to bear upon` the depressed surface ofthe clamp plate 3. 7 The outer surf; face of the plate 6 maybe of a suitable con-v figuration to give the desired ornamental' ef-` 1 feet in combination with the' plate ,3. At;

the central portion' of the rear surface ofthe plate V6 there is shown a rearwardly project# 65" ing portion 8, preferablyrectangular, adaptved'to extend through thesuitablyj'shaped aperture 9 inthe plate 5. A' rearfplate1.0v which'may be of any suitable shape,-is adapted to b'earvupon ythe rear surfaces of the impact bars in a position between the rearwardly extending Alugs4, 4. Abolt l1 passes through an aperture in the rear `plate 10 and is threaded into a hole inthe rearwardly projecting portion` 8 of the plate ,6.1 By` tightening the bolt ll the-washer or shoulder l2 will bear upon the rear surface ofthe rear plate l() and the two front plates will be drawn toward the'rear plate to hold th I impact bars in their proper position.

If the ornamental plate 6 and the clamp plate 3 arecast in onepiece itis very diflicult to polish vorotherwise prepare thefrecessed portion 5a. A clamp plate using my -invention may have itsseveral parts prepared for use by polishing, painting orl other means. l These finished kparts may be then assembled'` to formthe'clamp giving 4the Vdesired ornamental appearance. y g `f The-plate 3, providing a broad Vsurface of contact, need not be of material which will withstand tensile" stresses andthe smaller plate 6 maybeniade of aV different material and one which would provide asuitable anchor for the threads of the bolt fll. v If desirable, however, the increased strength ofthe plate 6 may be obtained byincreasing' the thickness 'o'f that'plate.* i

The projection 8 andthe aperture 9 are preferablyf rectangular, -or of some other leo angular form, in order that the plate 6 will vbeprevented from turning With the bolt 1l.

It is apparent that many other ornamental configurations may be used for both the plateak my invention being particularly applicable VWherewer the shape` of ktheassembled parts is such that narrow7 or irregular Y recessed surfaces are formed.v The desired ultimate designmay .be made up of any suitable'nurnber of complementary plates 'Which lmay be'interengaged to produce suchk design, or the plates may be interchangeable to give, different effects With different combinations'- of complementary plates. lt is furthery ap- `parent that more than tWo plates may be used v `to make up ythe complete design,-v and that y [these plates may beassem'bled one upon another-.or more thanone upon one plate.

is also apparent thatthe clamp plates embodying my invention maybe used With other Y arrangements of .bumpery bars and in order tol-do so they maybe suitably shaped toprovide the Vproper bearing surfacesupon such bars.v W
