I May 20, 1930. J. KINQUIST BRACKET FOR HIGHWAY USE AND THE LIKE Filed Dec. 23, 1927 Z/IL Patented May 20, 1936 UNITED STATES JOHN KINQUIST, OF SIOU'X CITY, IOWA BRACKET FOB. HIGHWAY USE AND THE LIKE Application filed December 23, 1927. Serial No. 242,107.

My invent-ion relates to brackets and has forits general object to provide a bracket of the type suitable for supporting mail boxes, road signs and the like and particularly use-,

ful in connection with highways where it is desirable to place a sign or a mail box as close aspossible to the road without subjectingthe supporting member to injury from collision.

More specifically, it is my purpose to provide a bracket attachable to a post or the like,

said bracket including a stationary portion and a swinging arm rotatably mounted on a vertical shaft in such a manner that should the arm be struck by a passing vehicle, it may swing to the side to allow the vehicle to pass without injuring the bracket structure. In

- this connection, it maybe stated that it is my purpose to provide the necessary parts for mounting such an arm in the manner hereinafter specified but that the arm itself may be supplied by the user ofthe device, a wooden plank orv the like, being well adapted to serve the purpose.

' A further object of my invention is to provide means to automatically bring the arm around to its normal position projecting over the roadway after it has been pushedaside.

With these and other objects in view, my

invention consists in the construction, ar-

rangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more full set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in

, to, a dotted line position being shown to indicate the extreme position of movement to I which the device may swing and from which it may automatically return to its normal position.

Fig. 2 is a transverse, sectional view through the roadway shown in Fig. 1, the device embodying my invention being shown in elevation;

Fig. 3 is a detail, sectional view taken on 5 the'line 3+3 o Fig. 4 illustrates a modified form of my invention.

I have used the reference character lO'to indicate generally the crown of a roadway having the drainage ditch 11, bounded by the usual parking or embankment 12, which is left between the drainage ditch and the extremity of the highway right of way.

It has been found necessary to place mail boxes andthe like over the parking 12 or at best at the edge of the drainage ditch 11 of the ordinary highway. To place them any closer would be to obstruct the highway. In many cases, mail boxes are placed over the highway by means of projecting arms, the 5 supports being positioned beyond the ditch, but even here, there is a tendency to obstruct the highway and should a collision occur with the mail box or its extended arms, it is very .probable that the arm will be torn completely from its support.

Roadsigns are ordinarily placed at, the side of the road where it is diflicult for them to be seenat night. Evenwith road signs placed at the side of the road and not'obstructing the highway, they are frequently demolished by passing vehicles.

The use of my invention makes it possible forditchers and graders to work without hindrance from road signs andthe like. The so upright support 13 may be placed as far from the road as is necessary to assure against collision. It comprises a stationary bracket A and a swinging arm B. The bracket A is preferably made in the form of a casting having a socket 14, connected by a lateral arm 15 to a mounting 16, adapted to be attached by means of bolts or the. like 17 to the post 13. Formed integrally with the upper extremity of the socket 14: is an annular. support bearing 18, which is provided with a notch 19,'shaped so as to form at its left side a helical cam face 20 and at its right side a vertical shoulder 21.

Supported in the socket 14 and extending up through the annular support bearing 18 is a shaft 22, which may be tubular or solid and which is secured in the socket I as by means of a pin or bolt 23.

The swinging arm B comprises an upper bearing 24 including an extending finger 25, to which the arm proper 26 may besecured j as by meansof bolts 27 and a lower bearing 28, includingan upwardly inclined arm 29 terminating in a horizontal portion 30, adapted to be secured as by means of bolts 31 to the underside of the arm proper 26. It may be noted at this point that the arm 26 has been shown in broken lines. This has been done to indicate that the arm proper 26 maybe supplied by the user of the deviceand may be of any dimensions 7. suitable to the particular purpose at hand. "The thickness of the arm 26 need not be limited to any particular dimension for, the reason that the, hearing 24 has a freefisl-iding connectionon the shaft 22 and the latter may be made sufiicientlyllong to receive the bearing 24 at various heights.

arm 26. h

The lower bearing of the swinging arm is provided with a downwardly projecting tooth 33, which is shaped to register with the notch 19 when the remainder of the bearing 28 is seated against the upper horizontal edge of the support bearing 18. The remainder of the bearing 28 is'shaped as a fiat ring.

The's'upport bearing 18 is provided with a shallow notch 34 positioned closely adjacent the upper extremity of the cam face 20'.

A pin 35 is'secured to the shaft 22 at a'disvary.

It may now be seen that, assuming the arm B to be in the normal position shown, should a blow be struck against the arm 26 by a vehicle traveling in the usual direction on the side of the road occupied by the bracket, the arm may swing laterally toward the position shown in Fig. 1 in dotted lines, the tooth 33 riding against the cam face 20 to lift the entire swinging arm upwardly. The weight of the arm will then cause it to gradually swing back to its position, since in so swing-- ing, it is traveling downwardly.

Should it be desirable to move the'bracket arm out of the way for a considerable length of time, as, for instance, when the road is being graded, it may be swung to a position where the tooth 33 rides over the hump between the notches 20 and 34 enters the notch 34 Obviously the point of the tooth will be retained and the arm supported in a position somewhat back of thatshown in dotted lines in Fig. 1, where the grading ma- A mail box 32 has been shown in dotted lines supported upon the end of the ably included within their scope.

chine may enter the ditch 11 without interference from the bracket. 7

The advantage'to the mail carrier of having the mail box supported out over the highway is no greater than the advantage to the county or State for the reason that during muddy weather, the constant driving past.

the side extremity of the crown of the road by the mail carrier has tendency to cut a deep i gash in the side of the road at that point and rains will widen this gash so as to make fre- ,qucnt repa r necessary.

" The advantage in being able to display a road sign at thevery edge of the road is equally apparent. Motorists traveling along the road will be confronted with the'signs where they will -receive thefull light from V 7' the headlights of the car. I

I have found that it is highly important that theupper bearing 24 'be simply a bearing and not co-active with a support bearing with a cam face similar to the bearing 18; .I'

have discovered that the latter construction is not successful in operation.

In Fig. 4, I have illustrated a, somewhat modified form of the invention, in which the inclined cam face 20 and shoulder21 arere- V placed by oppositely inclined faces20 and 21?, forming a notch 19 of the shape shown. The point 33 is replaced by a point 33 tofit the notch 19?. In this form of theinven'tion,

turning to itsnormal position from either the arm B may swing in either direction,.rei direction, and the inclined face opposite that 1 upon which thepoint 33 is riding,:serves as a stop instead ofthe shoulder 21.

Some changes may be made in the construction and arrangement; of the parts vof my invention without departing from the 'real' spirit and purpose ofmyinvention, and it is my intention to cover'by my claims, any

:modifiedsforms of structure or use of me- .chanical equivalents, which may be reason- I claim as my invention: 1. A swinging bracket including a support bearing having an 'annular'upper edge inclined upwardly in one direction, shaft proje t ng, pwardly rom th Cent o -sai bearing, and a swinging arm including an integral lower bearing provided with a downwardly projecting tooth shaped to register ceivinglthe shaft, said upper bearing includ- .with said inclined edge when in a normal position, an upwardly inclined braceon said 1 lower bearing terminating in a horizontal portion, and an upperbearing freely re-- ing an integral, horizontal arm, the said'hori- 1 zontal arm being adapted to be secured to a horizontally projecting, supporting arm.

' 2. A swinging bracket including a support bearing having an annular upper edge inclined upwardly in one direction, ashaft supported by and projecting upwardly from the center of said bearing, and a swingingarm including an integral lower bearing freely receiving the shaft and provided with a downwardly projecting element adapted to coact with said inclined edge when in a normal position, an upwardly inclined brace on said lower bearing, and an upper bearing freely receiving the shaft, said upper bearing and brace being adapted for attachment' to a horizontally projecting support arm, the support bearing being provided with" a comparatively shallow notch positioned adjacent the upper extremity of said inclined edge adapted to receive and retain the point of said element.
