Figure 1 is a vertical View, partly in section, of The guard 23 extends horizontally from post to 20 one of the supports or posts forming the main post and is adapted when struck, to transmit the 20 subject matter of this application; impact to a plurality of posts and to the spring Figure 2 is a rear view of the post, Figure l, 4assemblies thereon which absorb the impact with the web of the support I0 shown in section.; energy. Figure 3 is a top View of the post, Figure 1; and By providing the slot 22 in the guard rail, it is wherein-theimpact of the vehicle is received on lßiia-continuousgua-rd or `rail `supported on aplural 25 Figure 4 is a view, partly in section, of a preferred form of guard rail for use with the posts shown in the preceding figures. k Referring to Figure 1, the numeral I0 denotes an I beam of suitable dimensionsl forming a sup3o port. This may be driven into the ground to any desired depth. The web of the beam is drilled near the top to admit a bolt I3 to be presently referred to. 'rne numeral Il denotes a plate having the 35 downwardly extending flanges I2, I2 adapted to nt; snugly in the 1 beam. These flanges are drilled and bolted to the web of the beam by bolt I3. As the flanges iit the beam closely, the plate is firmly secured to the beam. It may be so se40 cured before the beam is driven in the ground and forms a convenient head for driving the beam. l The plate has one or more apertures I4 there- not necessary to very accurately space each post. 25 However, a steel cable can be used instead of the> guard rail, said cable being secured to the bolts 2| in any Suitable manner. By having the bolt IB above ground, the spring assembly can be replaced in case of damage Wîth- 3o out digging up the support IIJ. Also the plate II Can be replaced in CaSe Of breakage by removing the earth about the ñanges I2 and bolt I3 with out digging up the support I0. The support can. therefore, be safely set in concrete if desired'for 35 there is little danger of ever having to replace it in Case of Severe breakage t0 any 0f the parts ebOVe gI’OU-nd In Operatîûl’l, a TOW 0f the POStS may be Set alOng a highwayin the 1151121 mannen The Sup- 40 ports l0 may be buried in concrete and pockets formed about the heads of them to permit at taching the plates Il later. When the posts are through. Adjacent these is the upstanding complete, the guard rail 23 will extend along the 45 ñange I5. Secured to this flange by bolts I6 are highway a Sufficient height from the ground to 45 the resilient members I1, I8, forming in effect engage the average auto Wheel 0r bumper. leaf springs. Obviously any number of leaves Assuming there is an accident and an automo can be used on each assembly and one, two or bile strikes the rail 23, the force of the impact more assemblies can be used on each plate. The will be distributed along the rail to several sets of 50 physical dimensions of these springs and their spring assemblies or posts. In each assembly the 50 number and arrangement will depend upon the spring 24 will be ñexed and absorb some of the character of the safety system, that is to say, the impact. The remaining unabsorbed force is now «maximum impact the system must withstand, and this can be calculated in a known manner. 55 It will be observed that each spring assembly is transmitted to the springs I1, I8, which are flexed as shown at I9, Figure 1, which ñexing absorbs some more of the shock. The remaining undlssi- 55 2 2,136,415 pated force is transmitted to the stationary part of the post. By providing the springs I1, I8, 24 and inter posing them between the applied force of impact and the stationary supports l0, H, the danger of displacing the ñxed parts of the post assembly is minimized, and by providing a continuous guard member or rail 23 to distribute the impact over a number of these posts, the destructive force is 'I'he resiliency of the system causes the guard rail to spring suñiciently to 10 further dissipated. throw the automobile back toward the road to a greater degree than with systems using rigid posts and cables. 15 What is claimed is: » 1. A safety device comprising a support having a portion extending below the level of the guard, a leaf spring member secured thereto and extend 20 ing upwardly therefrom and having a portion extending downwardly below its point of attach ment to said support and below said ground level and overlying the side of the support, and a hori zontal guard member resiliently supported on said spring member. 2. A safety device comprising a support, a spring member secured thereto and extending up wardly therefrom and having a portion extending downwardly below its point of attachment to said support and overlying the side of same, a horizon tal guard member supported on said spring mem ber, and resilient means between said guard and its support. 3. A safety device comprising a support, an apertured plate secured thereto, a spring member secured to said plate and passing through said aperture therein and having a portion extending upwardly therefrom and a portion extending therebelow adapted to laterally engage said sup port, and a horizontal guard member extending across said spring member and supported thereby. 4. A safety device comprising a support, a plate secured thereto, a spring member secured to said plate and extending upwardly therefrom, a hori zontal rail extending across said spring member, and resilient means interposed between said member and rail whereby the latter is supported on said member. ' 5. A safety device comprising a support, a plate 10 having a ñange extending therefrom, means for securing said ñange to said support, a second ñange extending from said plate, a spring mem ber secured to said second flange, and a horizontal 15 guard member secured to said spring member. 6. In a safety system of the class described, a plurality of supports, resilient members detach ably secured to said supports comprising ñat springs having portions overlying said supports 20 and being attached thereto at points midway their ends, a guard member extending between said supports and supported on said resilient members, and resilient means between said guard and said members. 25 7. In a safety system of the class described, a plurality of supports adapted to be buried in the ground, plates adapted to overlie said supports and having integral flanges adapted to be secured thereto at a point below the ground level, re silient members extending upwardly from said plates and removably secured thereto at points 30 above the ground level, and a guard member se cured to said members and adapted when struck to transmit shock to said members to be absorbed 35 by the resiliency thereof.
