9 Claims. 1

My invention or discovery relates to pole construction in which a pole supporting at its upper end a heavy object such as a, neon tube lettered gasoline advertising sign, has its lower end mounted in a concrete foundation.

Prior to the present invention or discovery, in erecting a pole with such a heavy object mounted at it upper end, it has been necessary to use a crane, or to build scaffolding. After the pole and heavy object on its upper end have been elevated, it is furthermore necessary that the pole shall be positioned so that its longitudinal axis is vertical or plumb.

Prior to the present invention or discovery, there have been proposed hinged pole constructions including a base member which has been embedded in a foundation such as. concrete, the base member extending a limited distance above the top of the concrete foundation. The lower end of the pole has been hinge connected with the upper end of the base member above the concrete foundation, by various means which have required a multiplicity of parts which have been of complicated construction.

The object of the present invention or discovery includes the provision of an improved hinged pole construction including a simplified base member and a pole having a hinge connection with the base member, the base member being of simplified form, and the hinge connection being constructed by connecting the lower end of the pole with the upper end of the base member Without necessitating the use of special complicated parts.

Further objects of the present invention or discovery include the provision of such an improved hinged pole construction which is adapted for rapid plumbing of the pole with respect to the base member and concrete foundation by the use of simplified parts.

The foregoing and other objects are attained by the hinged pole construction, improvements, members, parts, combinations, and subcombinations, which comprise the present invention or discovery, the nature of which is set forth in the following general statement, and preferred embodiments of which together with their mode of use are set forth by way of example in the following description, and which are particularly and distinctly pointed out and set forth in the appended claims forming part hereof.

The nature of the improved hinged pole construction of the present invention or discovery may be stated in general terms as including a tubular base member which is adapted for being imbedded in a concrete foundation, and which extends a limited distance above the top of the concrete foundation. The tubular base member has a hinge member upper end portion above the concrete foundation, and the hinge member portion has a longitudinally extending opening at one side of the longitudinal axis of the tubular base member, the longitudinal axis being vertical when the tubular base member is imbedded in the concrete foundation. The tubular base member i preferably cylindrical and the side opening hinge member upper end portion preferably is formed by cutting out a segmental length or section of the cylindrical tubular wall at one side of the longitudinal axis of the tubular base member. A pole on the upper end of which is mounted a heavy object such as a sign which may include neon tube letters, according to the present improvements, is first laid at one side of the base member. Then the lower hinge member end of the pole which is dimensioned so as to fit with clearance in the hinge member upper end portion of the base member, is fitted in the hinge member upper end portion of the tubular base member, and is hinge connected therewith bya hinge bolt, shim or spacer means being located on the shank of the bolt and being interposed between the side opening hinge member upper end portion of the tubular base member and the hinge member lower end of the pole.

The pole and the object carried on its upper end is then swung upwardly. Adjacent the extremity of the hinge member upper end portion of the tubular base member, there is inserted and secured a second'bolt with shims or spacer members located on the shank of the second bolt between the wall of the side opening hinge member upper end portion of the tubular base member and the hinge member lower end of the pole. The cutout segmental section of theupper end portion of the tubular base member is then connected by a pair of bolts to the lower end of the pole and the side opening upper end portion of the tubular base member, shim and spacer means being mounted on the bolt shanks, and the second pair of bolts having their shanks extending at right angles to the shanks of the first pair of bolts.

By Way of example, preferred embodiments of the improved hinged pole construction and parts thereof are illustrated in the accompanying drawing forming part hereof in which:

Figure 1 is a side elevational view showing a preferred embodiment of the hinged pole construction after erection;

Fig. 2 is a fragmentary side elevational view with portions in section showing the tubular base member mounted in a concrete foundation, and the lower end of the pole after hinge connection with the base member by the lower bolt of the first set;

Fig. 3 is a fragmentary elevational view thereof looking in the direction of the arrows 3-3, Fig. 2, after the pole has been swung to the vertical position and has been bolted to the tubular base member; and

Fig. 4 is a transverse sectional view of the erected hinged pole construction as on line l4, Fig. 3.

Similar numerals refer throughout the drawing.

The improved pole construction includes a pole I after erection supporting at its upper end a heavy object such as a sign indicated generally by S. As shown in Fig. 1, after erection the pole I0 is mounted on a base member I I which is imbedded in a concrete foundation I2. The base member I I is connected with the lower end of the pole III by means of the improvements of the present invention or discovery as shown in Figs. 2, 3 and l. After erection the upper end of the base member above the foundation I2 is preferably covered by a sleeve I3 having a flange I4 at its upper end, the pole I0 extending through the flange I4 and the sleeve I3.

Some days before the erection of the pole I6 and sign S or other heavy object carried on the upper end of the pole It, the improved tubular base member I I is imbedded in the concrete foundation I2. The tubular base member II is preferably formed as shown of a length of cylindrical pipe and includes a, hinge member upper end portion I which is formed by cutting out from the wall of the cylindrical tubular member II a segmental length or section I'6 whose transverse curvature is less in arcuate length than the semi-circumference of the cylindrical tubular member I I, as best shown in Fig. 4.

After cutting out the segmental section I6, there is thus formed in one end of the cylindrical tubular base member I I a notch I'I best shown in Fig. 2, and the hinge member upper end portion I5 of the cylindrical base member I I, thus has a side opening bordered by side faces I8 and I9, and the width of the side opening is equal to or greater than the diameter of the pol I 0. As shown, and preferably, the pole I0 is also in the form of a cylindrical tubular pipe.

The longitudinal side faces t8 and I9 of the notch I! extend upwardly from a lower horizontal face after the tubular base member II has been imbedded in the concrete foundation I2, and the side opening of the hing-e member upper end portion I5 of the tubular bas member I! between the faces I8 and I9 is directed as may be most convenient at the site where the pole I0 is to be erected, such as at one corner of a gasoline filling station.

The segmental wall of the hinge member upper end portion I5 has formed therein above the lower end face 20 of the notch I! two sets of diametrically opposite apertures ZI, the centers of each set of which are on a horizontal axis passing through the longitudinal axis of the tubular base member I I.

There is also formed in the hinge member upper end portion I5 of the tubular base member I I a pair of apertures 22 whose centers lie in a vertical plane passing through the longitudinal axis of the tubular member II and at right angles to the plane containing the centers of the apertures to similar parts 2|. Each of the apertures 22 is spaced longitudinally above one set of the apertures M.

The segmental cutout section I6 which fits the notch I1 and by the removal of which the notch IT is formed, similarly has formed therein a pair of apertures 23 which have their centers longitudinally aligned in the median axis of the segmental section IB, and which also have their centers spaced longitudinally from each other the same distance as the longitudinal spacin of the centers of the apertures 22.

Each of the apertures 2|, 22, and 23 are preferably circular and have equal diameters.

After the tubular member II has been imbedded in the concrete foundation I2 and has set, preferably for several days, the pole I0 inserted through the flange M and sleeve I3 is laid at one side of the tubular base member I I with the lower end 2 of the pole I0 adjacent the notch IT. The lower end 24 of the pole It has formed therein two sets of circular apertures 25, each of which has its center on a diameter at right angles to the longitudinal axis of the pole I0 and is diametrically opposite one of the other apertures 25. Also, the apertures 25 at each side of the longitudinal axis of the pole It are spaced longitudinally from each other so as to be registerable and alignable With the spaced apertures 2! at one side of the longitudinal axis of the tubular member II, after the lower end 2 1 of the pole It has been inserted in the upper end portion I5 of the tubular base member I I.

The lower end 24 of the tubular pole ID has also formed therein two sets of circular apertures 28, each of the circular apertures 26 in each set being diametrically opposite the other, and at each side of the longitudinal axis of the pole In, the apertures 26 are spaced from each other longitudinally the same distance as the longitudinal spacing of the apertures 22 in the upper end portion I5 of the tubular base member II.

After the pole I0 has been thus laid down with its lower end 24 opposite the opening of the notch H, the sign indicated generally by S, and which may consist of a heavy rectangular metal box housing on outer rectangular faces 2'! of which may be mounted neon tube letters not shown, is connected with the upper end 28 of the pole II! by pivotally adjustable means, which may include as shown a bar 29 extendin at right angles to the pole Ill. The sign S is suspended on the bar 29 as by a pair of bar loops 30. The end of the bar 29 adjacent the upper end 28 of the pole I0 is connected as shown with a swivel or pivot fitting 3| which may be adjustably secured on the upper end 28 of the pole ID by means of a screw 3i-l. From the outer end of the bar 29 there extends a tie-rod 32 the upper end of which is connected preferably by a swivel or pivot fitting 33 with the upper extremity of the upper end 28 of the pole I0.

The sign S may thus be laid fiat on the ground adjacent the upper end 28 of the pole I0, and adjustably and pivotably connected therewith. Either before or after the connection of the sign S to the upper end 28 of the pole I0, as may be most convenient, the lower end 24 of the pole I0 is inserted into the opening of the notch IT so that the lower set of apertures 25 in the pole lower end 24 are aligned with the lower set of apertures 2I in the tubular base member II. A bolt 34 is then inserted through the aligned lower apertures 2| and 25 and preferably shim or spacer washers 35 are inserted on the shank 36 of the bolt 34 the segmental upper end portion (5 of the tubular base member i l and the lower end 24 of the pole is for'plumbing and spacin the pole ill in the direction of the shank 39 of the lower hinge bolt 34.

After the insertion of the lower bolt 34 through the lower aligned apertures 2i and 25 and the shim or spacer washers 35, a nut 3i may be screwed on the outer end of the lower bolt shank 36, or other securing means such as a cotter-pin may be used for maintaining the lower bolt 34 in assembled position as shown in Fig. 2 hinge connecting the lower end 24 of the pole Hi to the hinge member upper end portion !5 of the tubular base member It.

The pole Ill and attached sign S may then be swung upwardly on the lower hinge bolt 34, and after alignment of the upper apertures 22! and 25 with each other, an upper connecting bolt 34 may be inserted through the upper aligned

apertures

21 and 25 and preferably through an upper pair of shim or spacer washers 35.

The segmental section 16 may then be located in the opening of the notch I? between the side faces [8 and I9 as best shown in Fig. 4, the apertures 23 of the segmental section !6 being aligned with the apertures 26 in the lower end 2 1 of the pole I and with the apertures 22 in the upper end portion l of the tubular base member H. In each of the lower and upper sets of aligned

apertures

23, 26 and 22, a bolt 38 may be inserted, and there may be preferably interposed on the shank 39 of each bolt 38, shim or spacer washers 40 between the lower end 2% of the pole Ill, and the upper end portion 55 of the tubular base member II, and also between the pole lower end 24 and the segmental section i6, whereby the pole It may be plumbed in the direction of the longitudinal axes of the bolts 38, each of which has a nut 41 screwed on its outer end. After the pole I0 is thus erected, and, its lower end 2:1 is thus connected to the upper end of the tubular member I I, the sleeve it is slid down on the pole l0 so as to cover the connected parts of the pole i0 and the tubular base member H as shown in Figs. 1, 3, and i.

The hinge member upper end portion i5 of the cylindrical base member I! may be otherwise termed a longitudinally extending tongue or segmental wall which is curved about the 1ongitudinal axis of the base member, and which has a transverse cross section perpendicular to the longitudinal axis of the base member, and the transverse cross section being preferably a segment of a circle which has a central portion at one side of a diameter of the circle and has end portions extending beyond the other side. The tongue or segmental wall it has an open outer end and the side faces i8 and is spaced from each other and forming a side opening extending lengthwise of the base member H from the open outer end of the tongue or segmental wall l5.

In the foregoing description, certain terms have been used for brevity, clearness, and understanding, but no unnecessary limitations are to be implied therefrom beyond the requirements of the prior art, because such words are used for descriptive purposes herein and are intended to be broadly construed.

Moreover, the embodiments of the improved construction illustrated and described herein are by way of example, and the scope of the present invention is not limited to the exact details of construction.
