BARRIER.

Application filed April 6,

'l l n'sjinvention relates to barriers and has for 1ts"'ob3eet to provide a new and 1mproved device of this des-rrptmn. The 1nvention has as a further object to provide a eficient and quick acting stopping meehanism for the obstrm-tiug device that extends across the roadway, when it is struclcby a vehicle. The invention .has other objects which are more particularly pointed out in the accompanying description.

Referring now to the drawings: Fig. 1 is a front view of ohe'form of the device embodying the invention.

Fig. 2 is an enlarged sectional view taken on line 22 ofFig. 1.

3 is an enlarged viewin part section showing the combined weight and brake.

Fig. 4 is a side view of the construction shown' in Fig. 3. y

Figure 5 is an enlarged sectional View taken on line 55 of Figure 4.

Like numerals refer to like parts throughout the several figures.

Referring now'to the drawings; 7 I provide on each side of the-roadway the posts or supports 1 which are preferably connected together by the brace 2. Extending across between the supports is a flexible obstructing device 3 whichis engaged by the vehicle. This flexible obstr'ucting device is connected at each end with a weight and a brake mounted in each support 1, the con nection being made by flexible connections or cables *1 which pass freely through opening in the sliding carriers 5 which slide up al.;. .g the posts when it is desired to lift the obstructing device. These flexible connections 4 pass up the supports 1 and then pass :arouud pulleys (5 at the top and then down over pulleys 7 connected with the weight 8 and then are fastened at their ends to the rods 9 which pass up through the cross piece 1t) and are provided at their upper ends with (he springs 11 the rods 9 having nuts .or

enlarged heads 12 so as to compress the springs when the obstructing device is struck by a vehicle. Each support is provided with similar flexible connections, .pulleys and weights. When the obstructing device is 1923. Serial No. 630,237.

struck by a vehicle, these flexible constructions pay out through the holes in the sliding carriers 5 so as to let the vehicle move forward a predetermined distance. The flexible connections then exert a pull on the weight 8 and pull it up. the weight moving up at a slower speed due to the doubling back of .the flexible devices. The weight tends to retard the movement of the obstructing device 3. Associated with the weight is a braking device which also acts to retard the movement of the obstructing device with an increasing resistance so that it will be gradually brought to a standstill, thereby preventing injury to the occupants of the automobile.

This braking device is illustrated in Figs. 3 and 4 and consists of suitable brake shoes l t and 15 carried by the weight- 8. When the weight is moved up, these brake shoes engage the brake members 16 and 17 attached to the supports 1; The brake shoes are preferably provided with removable non 1 metallic brake blocks 18. Means is provided for pressing the brake shoes against the brake members 16 and. 17 as the weight -moves up and of automatically releasing them when the weight stops so that the weight can drop back when the pressure on the obstructing device 3 is released. I provide one or more springs 20. In the drawl have shown two such springs. These springs are located between the members 21 and, 22 and tend to spread these members apart. The spreading apart of these memhers is limited by the limiting device 21 by the link 23 and the member 22 is connected to the brake shoe 15 by the link 2%.

which, in this instance, are shown as bolts The link 23 is pivotally connected to the" brake shoe by the pivot 25 and with the member 21 by the pivot'26, While the link 2 1 is connected to the brake shoe 15 bythe pivot 25, and with the members 22 by the pivot '26. The pivots 25 and 26 are slightly out of alignment horizontally, the pivot 25 being somewhat higher up than the pivot 26, and the pivot 25 being somewhat higher up than the pivot '26. The link 23 is connected to the brake shoe 1 1 by a spring 27 and the'link 24. is connected to the brake;

shoe 1&- by a spring 28. It'will be seen from the foregoing that the brake shoes are move Htt ably connected with the members 21 and 22 of both of the springs 20. Located below the brake shoes are steps 29 and 230. These stops are located as shown in Fig. 3, so that; when the weightand the brake shoes are raised, the hralte shoes engage the stopsso that the pivots 25 land 2% will remain slightly above the pivots 26 and 26 so as to insure the release of the brakes as here inatter setout. When the obstruction device is struck by a vehicle. it is moved out and this moves up the eight 8, the weight takingthe first force ot the blow and tendine" first to retard the movement of the obstructing' device and the vehicle. the weight moves up, the brake shoes engage the braking elements 16 and 1"." and gradually stop the vehicle and the obstructing device. These braking elements may he of any desired length and l have shown them in Fig. 3, broken away. When the brake shoes engage the braking elements 16 and 1'? they are moved down to engage the stops 29 and 30 and this movement moves the parts 2i and 22 toward each other to compress tlu spring 20. Juring this upward movement of the brake shoe the pivots 25 and 2'? are slightly" above the pivots 26 and 2e, by the steps 29 and S0. The springs 20 exert; a pressure on the'bralte shoes to force them against the members 16 and 1?. When the upward movement of the brake shoes is stopped, the friction tending to force the brake shoes downwardly and outwardly withrelation to the members 21 and 22, is stopped and the brake shoes ere free to move upwardly andinwardly thereby reducing the pressure against brake members 16 and 17 and leaving; the Weight free to drop when permitted to do so by the cables 4:; thnt is, when the pressure on the obstructing device is released. In view of the fact that the outer ends of the links 23 and are higi e"- than the inner ends it will he noted that the springs 20 assist in releasing the brake shoes as the pressure'thereot tends to further hit the outer ends of these link the pressure on the obstructing device is released, the Weight and the brake shoes then drop beck to their initial position. The bottom of the brake device then strikes the stops 31 end 32. These stops are somewhat higher than the stops 2e and 30 so that the brake shoes Wiil fail hack to their roper position with the pivotsfiti and 25 ust slightly higher than the pivots and 26, the device then being ready for the next movement. The springs 27' and 28 assist in securing the desired result. It will he noted that in this construction the springs 20 have opposite actions under certain conditions. During the upward movement of the brake device the springs press, the brake shoes outwardly While when the upward movement s, and the weight starts down this presthereof, the brake shoes and ,associa weight movably mounted in each support.
