Application lied June 27, 1985. Serial lo. 89,091.

This invention relates to a mast such, for example, as is adapted to sup ortl an aerlal, and 1s particularly concern with certain features of construction by which it may be produced at small expense, be set up in` any one of several positions of adjustment, and be attachable `to walls or roofs of widely varying kinds. In the attainment of these.

objects, we associate with the mast a base having a detachable connection therewith, such as to permit of the base occupying any one of several different ositions of a justment relative thereto. y this vmeans the mast can be mounted u on a vertical wall or post, a horizontal or s anting roof, a gable peak, or elsewhere.

An embodiment of our .invention in its preferred form is shown in the accompanylng? drawing in the manner following igure 1 is a side elevation of the lower mast end together with base attached thereto.

Fig. 2 is a vertical section taken online 2-2 of Fig. 1;

Figs. 3 and 4 which are perspective views show the mast as attached'to a vertical wa or support;v

Fig. 5 shows in perspective the mast as mounted on a flat roof;

Fig. 6 which is also a erspective view shows the mastras securedp upon the peak or ridge of a gable roof; and

Fig. 7 also s ows in perspective a mounting of the mast upon a slanting roof.

The present structure comprises two units, viz, a mast A which is connected by bolts or otherwise to a base B. These parts are preferably made ofmetal, the mast being shown as having a T "section, and the base o being built up from a pair of plates or sheets. The two components of the base are counterparts of each other, each comprising an outturned flange 8 from which is obliquely extended an angular section 9 which 5 terminates in a supporting section 10 having a right an ular disp'ositlon relatlve to the flan 8. e thus 'provide a structure having tween the two sections 9 an angle of 90 or thereabouts which adapts the base to be seated upon a corner su port or elsewhere, orto present its two anges for securement to a fiat surface, as will more clearly ap ar hereinafter. One end 11 'of each of t ese three Vsections is mutually "5 aligned, and preferably in righangular re shown) are provided in readily be appreciated by lationto the adjoining edges 12 and 13 of the flan e and supporting sections respectively. e opposite ends 14 of these three sections,however, which are also in mutual alignment, are preferably slanted toward the other end 11 as it proceedsv upwardly from the flange section.

Two base components of this general character are 'arranged in complementary manner with the two supporting sections side by side whereby the angular sections 9 diverge downwardlyto present the fiange Sections 8 in spaced relation. The assembly of the two base components may be completed with the aid of bolts or screws 15. These are entered through registering openings of which four are provided, one proximate to each corner of the supporting sections. In addition, we provide other open lngs 16 in the angular sections and still ot er openlngs in the flange sections permitting the lnsertion therethrough of fastening devices, such as are suitable for securing the base to a Wall,-roof, or other support. 80

With a base of this general description, we associate the mast A which, as before stated, is preferably of T section with a head 18 and web 19. The mast web may be entered between the two supporting sections 10 along an one of its three edges 11, 13, or 14, in Whic position the head 20 may also engage therewith. A pair of openings not the mast an so spaced as to register with any twopadjacent openings in the supporting sections of the base whereby the fastening bolts or screws may pass through the mast web to effect a securement to the base. By this means we are enabled to attach the mast to the base in a manner which is both simple and rigid.

Certain of the advantages resulting from the construction heretofore described may reference to Figs. 3 to 7 inclusive, wherein is represented various conditions of installation. In Fig. 3 for example, we have shown the base secure to a vertical wall with the mast attached along the edge 13 of the base. In Fi 4, where the same assembly is used, the ase is shown as connected to a corner post of a building structure. In Fig. 5 the base is seated upon the peak or ridge of a gable roof and in Fig. 61it isj secured upon a fiat surface. .In each of these last two figures the 110 mast is assembled along the front end 11 of the base. Fig. 7 shows the mast mounted upon a slantmg roof, and connected with the basealong its rear edge 14. In this manner, the mast is supported in a substantially `upright position even though the. base be end of each rod is secured to the building construction at a desirable place.

The present invention is meritorious in many respects, notably in the simpllcit of the structure, the economy with whic it may be produced, the ease with which it may be set up and installed, and the several adjusted positions which it may occupy with relation to its base. Because of features such as these, the mast will satisfactoril fulfill all the usual conditions, and serve e fectively for its intended purposes.

We claim 1. A mast of T-iron having a base with two plates arranged on opposite sides of the mast web whereby the mast head may engage with one edge of each plate, there be- 1n a plurality of openings through the mast weil) and the two plates so arranged that those of the mast may register with certain of those in the plates which are proximate to one4 ed e `of each, and means extended through t e registering openings of the mast and base in a manner to secure ,the one removably to the other in a selected position of adjustment, substantially as described. i

2. In combination, a mast and a two part base of sheet metal, the mast being formed with a web adapted to lie between the base parts and with a head for en aging with one edge of each, and means w ereby the mast may be removably secured to the base along any one of three edges thereof, substantially as described.

3. In combination, a mast and a base therefor consistin of two complementa lates arranged si e by side, means exten mg laterally from the mast between the plates proximate to a securing edge thereof whereby a portion of the mast remaining exteriorly of the plates may engage with said edge and be supported in a-llgnment therewith, connecting means extended through the ltwo lates and laterally extended portion of t e mast in a manner to secure the one removably to the other, the mast having 00 three such 'securing edges, one in right angular' relation to another and the thirdobliquely disposed to the other two whereby the mast may be connected to the base in alignment with any one of said three edges,

substantially as described.

4. In combination, a T-iron mast and a double plate base adapted to engage the mast flange upon opposite sides, each base plate having a securin section with three free' 'l0 edges, one vertica one horizontal, and the other disposed obliquely to the other two, there being in the mast web two openin andy in each base plate four openings simllarly spaced in consecutive order, one proxi- 'I5 mate to each end of said three edges, and means passing through two adjacent holes of each plate and through the mastl holes to connect the mast removably to the base alon an selected of the threefree edges thereo su tantially as described.
