This invention relates to an improvement in cable guards for use on bridges and highways and also provides an improved bracket or support for the cables of such guards.
One of the principal objects of the invention is to provide a cable guard of this type wherein the cable is so supported and mounted with respect to the post that it will serve to prevent automobiles or other vehicles colliding therewith from striking the posts, the cable causing the vehicle to glide past such posts without interference or colliding impact and danger, thereby avoiding damage to the vehicle and possible inj ury to persons in the vehicle.
Another object of the invention resides in the provision of a novel form of bracket designed to firmly and rigidly secure the cable in spaced relation to the post.
Another object of the invention is to provide a bracket or cable support of this character which is simple and durable in construction and comparatively inexpensive to manufacture.
Other objects 'and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described'and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification, and in which Figure l is a perspective view showing a cable guard. constructed in'accordance with the present invention,
Figure 2 is a longitudinal section of the bracket shown applied with its support in vertical section and the cable supported thereby in transverse section.
Figure3 is a detail perspective view of one of the brackets,
Figure 4 is a plan view of one of the brackets, a fragment of the post to which it is fastened being shown in horizontal section, and
Figure 5 is a sectional view on the line 5-5 of Figure-4.
Referring to the drawings it will be seen i that the guard embodying the present invention includes posts 1, which may be made of metal, concrete or wood and each of which has supported thereon and rigidly and positively connected thereto a bracket, designated generally at 2. The brackets 2- support a cable 3 in inwardly spaced relabolt extending through 9 being integral with the walls on which they are carried and having openings for co-action with screws or bolts 10 which serve to'f'asten the bracket to the post 2 on.
which it is mounted, as clearly indicated in Figs. 2 and 4, the wings 9, extending on the opposite sides of the post and the wing 8 being fitted flush up against the portion of the post which confronts the roadway. With the brackets so mounted on the posts they extend inwardly from the posts toward the roadway in a substantially horizontal plane and at their inner ends-the brackets are provided with means for supporting and fastening the cable 3. For this purpose each side wall 7 is provided with a curved cable seat 12. The top wall 5 is provided with an integral cable clamping element 13. The brackets are constructed of metal which is sufiiciently heavy and rigid to enable the Y and to permit of the formation of a resilient clamping member or tongue 13. The clamping. member or tongue 13 extends around the cable 3 as shown in Figure 2 and it is held in clampin engagement with the cable by means of a olt 14 and nut 15, the an opening in the tongue 13 and throug an openin 1n an attaching lug 16 which may be struc from the bottom wall 6 of the bracket. The portion of the bolt which projects inwardly of the lug 16 is engaged bythe nut 15, the'nut 15 also engaging the attaching lug. One cornor of the attaching lug may be bent over, as at 17, to prevent accidental disengagement of the nut 15 from the bolt 14. The tongue 13 is so shaped as to eliminate a square shouldered obstruction on the guard where the tongue wraps around the cable thus reducing the possibilit of serious impact between a vehicle an the bracket in case of contact with the guard avoiding breakage of the bracket and deflection of the vehicle b the bracket.
With t e brackets described the cable 3 is rigidl and firmly supported in inwardly space relation with respect to the posts 1 so that should an automobile when skidding or out of control or for any other reason collide with the guard cable 3 the cable will not yield appreciably and the vehicle will glance or slide along the cable and will not be damaged as it otherwise would were it permitted to come into destructive contact with the posts 1. Moreover this gliding contact of the vehicle with the cable operates to rectify the direction of travel of the vehicle causing it to move parallel with'the guard thereby avoiding serious damage to both vehicle and guard. In the present practice the cables when employed are fastened directly against the posts so that an automobile colliding with the cable eventually smashes up against one of the posts and thereby greatly injures the automobile and sometimes the occupants' Applicant by spacing the guard cable inwardly a substantial distance avoids the possibility of the automobile colliding with the posts.
I claim 1. A bracket com rising a tubular body portion having wa s provided at one end with cable seats and having a wall formed with a clamping member extendable around thecable for holding the same against the seats, an attaching lu on the body portion in spaced and oppose relation to a portion of the clamping member, and fastening means cooperable with the clamping memher and the lug for causing the clamping member to force the cable against said seats.
2. A bracket comprising a tubular body portion having wings at one end adapted to be fastened to a post or the like, certain of the walls of the tubular body portion having seats at the end of the body portion opposite the wings, said seats being designed to receive a cable, and means for clamping the cable against the seats. 7
3. A bracket comprising a tubular body portion having wings at one end adapted to be fastened to a post or the like, certain of the walls of the tubular body portion having seats at the end ofthe body portion opposite the win s, said seats being designed to receive a cab' e, means for clamping the cable againstthe seats and comprising, a clamping tongue inte rally formed with one of the walls of the ody portion and extendable around the cable, a lug on the body portion, and a bolt and nut for drawing the clamping tongue toward the lug and consequentl toward the seats.
4. A racket comprising a tubular body portion having wings at one end adapted to be fastened to a post or the like, certain of the walls of the tubular body portion having seats at the end of the body portion opposite the wings, said seats being designed to receive a cable, means for clamping the cable against the seats and comprising a clamping tongue integrally formed with one of the walls of the body portion and extendable around the cable a lug on the body portion, and a bolt and nut for drawing the clamping tongue toward the lug and consequently toward the seats, said ug havin one corner bent over to revent acciden displacement of the nut rom its bolt.
