MAIL-'BOX SUPPORT.

Application filed `August 18, 1926. Serial No. 130,030,

rIhis invention relates to mail box supports and has for its primary object to provide a device of this character to permit of the support of a mail box upon a distended arm that is capable of oscillatory movement so that the box may be moved upon'its being struck by any object without resulting in the fracturing of the device or in any manner whatsoever impairing its utility.

An additional and important object is to provide a mail box support of the aforementioned character that is extremely simple of construction, inexpensive of manufacture and highly adaptable for the purpose intended.

A still further object is to provide a mail box support wherein the height of the same may be regulated and wherein the length of the box supporting arm per se may be increased or diminished to meet the required conditions.

Other objects will become apparent as the nature of the invention is better understood, the same comprising the novel form, combination, and arrangement of parts hereinai'ter more fully described, shown in the accompanying drawing and claimed.

In the drawing wherein like numerals indicate like parts:

Figure 1 is a view partly in side elevation and partly in cross section of a. mail. box support constructed in accordance with the present invention. i

Figure 2 is a detail longitudinal section taken substantially upon the line 2 2 oi Figure 1, and c n Figure 3 is a view taken on the lme 3-3 of Figure 1 for more clearly disclosing the means whereby the mail box supporting arm per se will be automatically turned to its normal position should the same be struck by a vehicle or other object passing along the road.

Now having particular reference to the drawing, my novel mail box support constitutes the provision of a hollow post 5 of su1table length equipped with a suitable anchor 6 whereby the same may be rigidly secured within the ground.

Telescopically arranged within this post 5 is a solid bar 7 upon which is slidably arranged a collar 8 that carries a set screw 9. By reason of this collar and set screw the bar 7 may be maintained in any desired extended position with respect to the hollow post 5.

Directly beneath the collar 8 there is secured to the upper end of the post 5 a cross arm 10 while secured to the bar 7 in pre` determined spaced relation with the arm 10 is a similar arm l1. Inter-connecting the opposite ends of these arms 10 and 11 are retractile elongated coil springs 12-12.

Arranged upon the bar 7 above the collar 8 is a circular metallic clamp 13 to the outer side of which is pivotally secured as at 14 a horizontal mail box supporting arm 15 that consists of a pair of telescopic sections that may be maintained in predetermined ad- Justed position by reason of the set screw 16 threaded through an opening in the outer end of the hollow section. Secured to the outer end of the outermost section is a mail box supporting plate 17 upon which may be suitably secured a desirable form of mail box A.

Upon the upper end of the bar 7 slidable within the hollow post 5 is an outwardly extending slightly depending hook 18 to which is secured one end of a retractile coil spring 19 while secured to the opposite end of said coil spring is a chain length 20 that is in turn secured as at 21 to the hollow section of the adjustable mail box supporting arm 15 as more clearly disclosed in Figure 1. It will thus be seen that the mail box supporting arm 15 may be raised or lowered either forcibly or manually, but will nevertheless seek a normal horizontal position by reason of the spring 19 and chain 20. Consequently should any pressure on this arm occur in a vertical direction no stress will be upon the pivotal connection 14.- or upon the clamp 13 as the same will be readily taken care of by the spring 19.

It will also be seen that should the arm 15 be struck by an object moving along the road, the bar 7'will turn within the post 5 which turning action will cause the arm 11 to move with respect to the arm 10 which action will force the expansion of the springs 12--12 and consequently when the pressure is released, said spring will return the mail box supporting arm 15 to its normal position.

Even though I have herein shown and described my invention as consisting of certain detail structural elements it is nevertheless to be understood that some changes may be made therein without effecting the spirit and scope of the appended claim.

Having thus described the invention, what pivotally secured at its inner end to the bar, 10 V I claim is'zand spring means interconnecting the said In a mail box support of the character de# mail box supporting arm and the upper end scribed, a ground engaging hollow post, aY of the bar for maintaining said arm in nor- 5 bar telescopically arranged Within the post Vmal horizontal position."
