Figure 3 is a sid elevation of the form of suspension element employed, anchored against the a front of a vertical support,

Figure 4 is a perspective view of the found suspension element, I

' gure 5'is'a view similar to Figure 3 showin the assembling of a guard rail relative to a combined clamp and suspension element, and v 6 is a vertical sectional view of amodifled form of guard device in accordance with this invention.

The guard device includes a plurality of side-- wise aligned spaced intermediate posts II and a pair of end posts ll (only one shown) spaced Each post II is of like form and is formed of a body l3,.preferably wood, having flat side faces ll, a flat front face II anda fiatrearface It; The top" ofthebody l3 inclines downwardly from front torear. The posts III, in pro ty totheir upper ends, are

formed with openings ll which extend from the a 40 front to the rear faces thereof. The posts ll have their lower portions anchored in the ground adjacent to the side of aroadway. Theposts ll also are to havetheir lower portions anchored in theground I, but are to extend a greater dis- 5 tance abovethe ground than the posts II. The guard device also includes a bow sha metallic guard rail 25 formed of a plurality of intermediate sections 21 and a pair'ofendsections 28. Only one end section 2! is shown. The

2 ofthe sections 2! are anchored together in abutting engagement by the spaced holdfast means 3 l Positioned against the inner face of an end section is a one-piece angle-shaped element 32,

which provides a reinforcement for an end of the guard rail. The element 32 also provides a connector and abutment for a resilient coupling and suspension structure 12 for the guard rail.

The guard device also includes extendible and contractible open front resilient combined guard rail clamping and suspension elements of like form and which correspond in number to the number of posts I 0. Each element 45 is an-- chored against the front of a post II. The elements 4! are of like form and each is constructed of a resilient metallic strap of the desired gauge bent to form a vertically disposed rear part 46. terminating at its ends disposed spaced upper and lower segmental inner coupling parts 41, 48, which merge respectively into a pair of spaced oppositely extending endwise and lower channels or grooves 51, 5| respectively to receive a guard rail or a guard rail section. The part 38 vextends above the inner coupling-41. 'Ihe part 54 depends below theinner coupling part 48. The rear part 46, centrally thereof, is formed with an opening 59. The parts 48, oppose and are spacedfrom part it by the parts 41, u. The

parts 53, I4 oppose and are spaced from the parts 49, 5| bythe parts ll, I2. The parts 41, 48 are of greater length than the parts iii, 52. The jaws l5, 5! are of semi-circular contour. v The part 48 is positioned against the front face of a post ll and with its opening I9 registering withopening l8. Extending-through the registering openings I l, I! is a threaded bolt i0 having a head II and carrying washers i2, 83 and a clamping nut 64. The washer I2 is interposed between part 46 and bolt head II. The washer I is interposed between nut 84 and the rear face I of post II. The bolt 80, washers 42, I3 and nut 04 coact with the post II and part 4 for anchoring element 45 to the post. Thereisassociated with eachpost Ila bracing, means therefor which is to be anchored in the ground. Y r a Whenthe guard rail is to be resiliently suspended, the bottom of the rail isplaced in ,the

lower channel ll of element 45 and the top jaw of such element is then any suitable tool for the P pose of having the top of the rail seator extend into the upper channel ll of element-45 whereby the be'clamped to element 46 and resiliently suspost l0. Preferably the guard rail will be formed of the intermediate sec tions 21 and a pair of end sections 2l. Only one end section is shown. One of the sections 21 will be connected to one of the elements 45 in the manner asreferred to and after which another section 21 will beconnected to an adjacent element llinamannerasreferredtmbutwithan end of the second connected section 2! overlapping an end of the first connected section 21.

sprung into place by into a pair of oppositely V -ment consisting of a formed of a vertical rear ends into a pair of oppositely disposed superposed spaced upper and lower. inner coupling parts merging into a pair of oppositely extending superposed spaced upper'and-lower vertically disposed terminating into a The overlapping ends of such sections 2? will then be connected together by the hold-fast means II,

After the desired number of the sections 21 are clamped to the elements 45, an end section 2| is secured to an outer end portion of an outer section 21. When section 28 has been secured to section 21, the section 28 is resiliently and slidably connected to a post H by the structure 12-.

With reference to the modified form of guard device shown in Figure 6. It will be of the same construction as that shown in Figure 1 with the exception that a pair of superposed guard rails and two sets of superposed extendible and con tractible open front resilient guard rail clamping and suspension elements are employed. In Figure 6 an intermediate post is designated 89 and itis formedwith a pair of superposed openings 00, 9|, Extending through the openings 80, 8| are anchoring means 82, 93. Secured to the front of the post 89 by the holdfast means 92, II are the upper and lower combined clamping and suspension elements 84, respectively for the

guard rails

96,91 respectively. Each holdiast means corresponds to the headed bolt 60, washers and nut 64. The combined guard rail clamping and

suspension elements

94, 95 are of like form and correspond in structure to that of the elements 45. The guard rails 91, the same form as the guard rail 26. posts H, the bracing means 63 for the and the resilient structures 12 will be in the form shown in Figure 6.
