POST CONSTRUCTION Filed March 20, 1936 jaw/22 01:

Patented Dec. 28, 1937 UNITED STATES PATENT OFFICE This invention relates to post construction, and is more particularly concerned with a tiltable post adaptable for. supporting barriers and other kindred uses, such, for example, as supporting corner 1 signs, 'trafiic signals, etc., which are apt to be collided with by vehicular traffic. I

Broadly,-the primary object of the present invention resides in providing a simple, economical and durable post, which is normally supported in a vertical. position upon suitable anchoring means, but which is tiltable about such anchoring means in all directions, wherebyit will yield should it inadvertently be struck by a. vehicle or other moving object, and will automatically re-' sume: its normal vertical position'upon being relieved 'from pressure.

More specifically, the present invention contemplates a construction of post comprising a standard 'or'casing of tubular shape, each of the ends of which are closed bya flanged cap. These caps are substantially identical in construction, both for convenience in manufacturing-and so that they may be interchangeable with respect to the ends of the standard. Each of the caps is provided with a projecting portion in'the form of an "external ear, which is disposed exteriorly of'thestandardwhen the cap is in place thereon, and with'a'circular stud, also having a projection in theiorm of an internal ear, both the stud and thewinternal ear being adapted to project within the standard when the cap is in place:

thereon; .The' flange. of the upper cap seats on the standard, while the standard seats on the flange of the lower cap. Resilient meansv in; the

' formof a coiled tension springis confined within the standard and is. connected at one end with .theinternal ear of the :upper cap, while at its opposite end the spring is connected with the internal earf the lower cap. This spring secures thecaps to the standard, and the standard is,=therefore, confined between the'caps. The externalear of the upper cap' is adapted to have any desired device secured thereto, while the lower-cap is adapted to be embedded in an anchor, with the upper surface of the flange of said cap disposed" substantially flush with the upper surface of the anchor. The anchor is-sunk in the ground, with its-upper end substantially flush with ,the ground line. Preferably, a rod extends through the external ear of the lowercap), at

,ard provides :a fulcrumfaboutj which the post may tilt, and the resilient means connected between the caps serve to normally hold the post in a vertical position or, when the post has been tilted by reason of contact of a moving body therewith, to return the post from such tilted '5 position to its normal vertical position when the pressure is removed therefrom.

From the foregoing, therefore, it will be apparent that the post of the present invention is resiliently mounted upon a countersunk supporting anchor and tiltable. at the ground line in a manner to permit the same to be tilted or knocked down without damaging it, the resilient mounting of the post restoring it to its normal vertical position after such impact. Thus a post embodying the salient features of the present invention eliminates unsightliness wherever employed due to collision therewith by moving bodies, and at the same time eliminates frequent repair costs such as are required with posts which are bent, dented, or broken by such collisions.

Other features and advantages of the present invention will appear from the following detailed description of the preferred embodiment of the invention illustrated in the accompanying drawing, in which:

The single figure is an axial section through a post embodying the principles of the present invention, certain parts being shown in section.

Referring now in detail to. the drawing, the

7 post comprises a rigid standard: 3 of tubular formation, which may be formed ofany suitable or preferred metal. At its upper end, the standard is closed'by a cap 4, while the lower end of the standard is closed by a cap 4. These caps may. also be formed of any suitable or preferred metal andaresubstantially identical in construction, to provide for' convenient manufacturing, and so that they may readily be interchangeable with respect to the ends of the standard.

' The caps 4 and 4' may be castings, and each comprises a body portion which, in the present instance, is in the form of a relatively thick disc 5, although it may .be of any other suitable or preferred form. Substantially centrally thereof, one side of the dischasarelatively narrow and integral ear 6 projecting therefrom, while on its opposite side, the disc is provided with a relatively thin and integral disc, I. This-latter disc islof greater diameter than disc to form an outwardly extending annular flange 8. A circular stud 9, reduced in diameter with respect to disc 5, is formed integrally with the free face of disc .1, and substantially centrally thereof, and projects outwardly therefrom for a. relatively short distance. At its outer end, the stud is preferably beveled as indicated at In, and the free end thereof has a relatively narrow integral ear H projecting outwardly therefrom. Ear 6 is preferably provided with an opening I2, while ear H has an opening it therethrough. As shown, face I l of disc I of the caps is adapted to engage the marginal edges of the ends of standard 3, the upper cap 4 seating on the standard, and the standard seating on the lower cap i, when the post is in normal upright position. In such. position of the caps with respect to the standard, the studs 9 and the ears I l are disposed within standard 3, the studs having a relatively loose or sliding fit with the inner surface of the wall of the standard. These studs restrain lateral movement of the caps with respect to the standard, and the caps are secured to the standard by yieldable means it associated with the ears ll. This yieldable means is a coiled tension spring, which is entirely confined within the standard and is provided with a hook it on each of the free ends thereof. These hooks, as shown engage through openings l3 in ears H, thereby yieldingly securing the caps to the standard.

The post is normally supported in an upright position by suitable anchoring means II. This anchoring means, in the present case is a concrete form, which is sunk in the ground with its upper face l8 disposed substantially flush with the ground line 59. The lower cap 4' is embedded and anchored in the concrete form, with its face l4 disposed substantially flush with the upper face It of the form.

As the caps are interchangeable with respect to the ends of the standard, the ears l2 may be employed'for either of two purposes. When used as a lower cap, a rod 28, if desired, may be passed through the opening 12 in the ear to provide additional anchoring means for the cap in the concrete form. When used as an upper cap, the ear provides means for attaching any suitable device to the post. Such device may consist of a signal, when the post is used for traffic purposes, or it may consist of suitable barrier means when the post is employed in fence construction.

From the foregoing, it will be apparent that as the standard is confined between the caps 4 and 4' it will normally be supported in an upright position by the yieldable means l5. Should the standard, however, be struck by a vehicle, or subjected to some other lateral or transverse pressure, it will tilt about the stud 9 of the lower cap l as a fulcrum, as shown in the dotted line positions of 'the standard in the drawing. Such tilting of the standard about the stud 9 may be in any direction with respect to the axial center of the standard. The beveled portion I of the stud permits such tilting movement of the standard without binding between the standard and the stud. When the standard is relieved of the impact or pressure, it will be returned to its normal upright position by the action of the tension spring.

While there is herein shown and described the preferred embodiment of my invention, it is to be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.
