RADIO MLAST SEAT.

- Application filed March 12, 1923. Serial No. 824,890.

To all whom it may concern:

Be it'known that we, HARRY C. HANFORD and MARTIN H. LANG, citizens of the United States, residing at Minneapolis,- in the a county of Hennepin and State of Minnesota, have invented certain new and useful Im rovements in Radio Mast Seats, and we do ereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

Ourinvention provides a simple and hi hly eificient mast seat especially adapted or holding radio masts, flag poles and the like,

and, generally stated, the invention consists of the novel construction and combinations of parts hereinafter described and defined in the claims.

This improved mast seat is of such construction that it will fit any type of roof, whether flat, a plain peak or peak with a ridge roll, and, moreover, it is adjustable to diiferent roof an les and is adapted to be applied to a roo or other structure in positlon to support a mast or pole vertically,

orizontally orat an oblique angle, if desired.

In the accompanyin drawings, which illustrate the invention, like characters indicate like parts throu hout the several views.

Referrm'g to the rawings:

Fig. 1 is a side elevation showing the improved mast seat; v

. Fig. 2 is an end elevation of the same;

Figs. 1 to 5, inclusive, illustrate the improved mast seat designed as a cast metal structure, and this construction will first it be described. The receivin socket of the mast seat, which is adapt to receive and hold the base end of the mast or pole y, is made in two semi-cylindrical sections 7 cast integral with ridge flanges 8, which, 'in length, are much wider than the socket sections and are formed with abutting upwardly extended ears 9 tlirough which nut- 3, 4nd 5 are side elevations show- 0' mast seat applied in different ways;

equip ed bolts 10 are passed to rigidly connect t e two sections.

The rid e flanges 8 are thus rigidly connected an' it is important to note that they have a downward convergence and form, at the base of the socket, an approximately cylindrical concave surface 11, which, as Wlll presently be noted, is adapted to span and so clear a ridge roll such as the custom-a semi-tubular galvanized metal ridge rol found in very extensive use.

At the lower edges of their ends, the ridge flanges 8 are ormed with hinge In .85 12 to WhlCll, by means of rivets 13, t5: lugs 14 of adjustable roofflanges 15 are directly hinged. By means of wood screws, not shown, applied through screw holes 16 in the flanges 15, the latter are adapted to be directly anchored to a roof or other building structure and any one of the several adjustments shown in Figs. 2, 3, 4. and 5, or in intermediate positions. Obviousl the hinge or pivotal actions of the so-call roof 7s flanges make it possible to fit the device to any roof or simllar structure, whether fiat, angular, oblique or perpendicular. Obviously, when the huts of the bolts 10 are tightened, the mast or pole 3 may be very so firmly clamped in the socket.

Fig. 2 shows the device adjusted for application to the ridge of the roof having a pitch of approximately forty-five degrees.

ig. 3 illustrates the use of the device to as support a mast in a vertical position from a fiat surface. Fig.- 4 shows the .device used to support a mast in a vertical position on the surface of an oblique roof, which has a pitch of approximately forty-fivedegrees, and in this arrangement, a spacing block is placed between the roof and one of the roof flanges 15. In the arrangement illustrated in Fig. 5, the device is applied to the side and top of a rectangular structure '05 and 'tioned to support the ole or mast in a htn'i zhntal position. In Fig. 2, the nu-' meral 17 indicates a shwt metal ridge roll having an approximately semi-cylindrical ridge roll 18. This view, Fig. 2, shows the important purpose of the concave surface 11. .Fig. 6 shows substantially the construction alread described, but in which the elements of e seat are stamped from sheet metal. In this construction, the socketforming sections 7 are formed with ears 9 connected by short nut-equipped bolts 10, and the ridge flanges 8 are formed with turned hinge lugs 12*, which by pins or rivets 13, are connected to lugs of the roof flanges 15,

What we claim is: v 1. A mast seat comprising an approxi mntely semi-cylindrical body adapted to clean a ridge roll, said semi-cylindrical body neoneee at its intermediate portion heving en EXP- standing socket and having anchoring flanges irectly hinged to its opposite edges, 2. The structure deed in claim 1 in which said body and socket we vertically split and have means rigidly connecting its sections together.

In testimony whereof We at our signetures.'
