JACOB GIPSON \VALTON, OF DAVILLA, TEXAS.

WlNDMlLL-TOWER.

SPECIFICATION forming part of Letters Patent No. 465,079, dated December 15, 1891.

Application filed August 22, 1891. Serial No. 403,468. (No model.)

the wheel or whatever is supported thereby may be lowered to the ground.

To this end the invention consists in a skeleton base, a mast or pole pivoted at about the center of its length to the upper end of said base, and the specific details and construction of these elements and the various features thereof, all as hereinafter more fully described and claimed, and as illustrated on the two sheets of drawings, wherein- Figurel is a general elevation of my invention, showing the mast as raised and a windwheel-as supported at the upper end thereof. Fig. 2 is a front elevation of the base. Figs. 3 and 4 are cross-sections of the base on the lines 3 3 and 4 4, respectively, of Fig. :2. Fig. 5 is a front elevation of the mast. Fig. 6 is an enlarged cross-section on theline 6 6 of Fig. 5. Fig. 7 is a perspective detail of the look at the lower end of the mast.

In the said drawings, B is a skeleton base rising from the ground. M is a mast jour- 'naled at J to the top of the base and at the center of the mast. XV is the device supported by the mast and adapted to be raised high into the air, (in the present case being a wind-wheel.) C is a counterbalancing-weight for the wind-wheel, and L is the latch or look for holding the mast upright when it is raised by the rope R, these parts being respectively of the following construction:

The base B comprises, preferably, fOll1COlnor-posts 1, which may be of L-iron, as seen in Figs. 3 and i, and which posts converge from their lower to their upperendsand form a square truncated cone. The posts are braced at various points throughout the height of the base by stringers 2, which close all sides of the base save one, and the several stringer-frames thus formed are connected as best seen in Fig. 4that is to-say, the

stringers 2are connected by inclined braces 6 across the anglesinside the base and remote from its open side. The upper ends of the posts 1 are connected in pairs by twohorizontal bars 7 for supporting the journal J, de-

scribed below.

The mast M comprises the following elements: '10 is a shaft extending across the cen' ter of a rectangular frame 11 and preferably braced therein by a transverse bar 12,'extending across the frame atright angles to the shaft. At the center of the shaft threaded bosses or sockets 13 extend upward and downward, and into these sockets are screwed the inner ends of two long pipes or tubes 111:, whichconstitute the mast proper. The outer end of one tube is screwed into a stub-shaft 15, which has a horizontal perforated flange 16, and on which is supported and pivoted the wind-wheel or other device which is to be carried by this improved tower. The outer end of the other tube passes through a box or casing 17, which contains stones or other Weights and constitutes the counter-balance C for the wind-wheel IV, the casing being rigidly secured on the tube. Four truss-rods 18 lead frointhe holes in the flange 16 through notches in the corners of the rectangular frame 11 and connect with the inner face of the casing 17, these rods being drawn very taut and bracing the tubes against deflection in any direction from'their properalignment. The rods may be connected at suitable' points by braces 19 to prevent their being stretched and rendered slack under the in fluence of strong winds.

The journal J between the center of the mast and the upper end of the base is con structcd as follows.- The ends of the shaft 10 project-beyond the frame 11 and form bear ing-journals 20, which turn in journal-boxes 21, located at the centers of the horizontal top bars 7 of the base. Inside each bearing a large disk or ring is mounted concentrically around the journal of the shaft with which it turns, this ringpreventing the accidental dislocation of the journals from their boxes, which might occur when the .mast is swungduring a high wind. Such swinging of the mast is accomplished by means of the ropeR in a manner which will be obvious, and as the mast is drawn down around its journal it strikes a buffer-spring 23, secured to one of the stringer-frames, whereby the jarringof parts is cushioned.

The latch or lock L for holding thennast raised is best seen in Fig.7. It comprises a tubular body 30, sliding on the mast proper between the outer face of the casing 17 and a stud or set-screw 31 inserted in the mast, and the body has a depending tongue 32, which is adapted to be dropped over the curved rod 5, which connects the angles of the V-rods i, as above described. Thus it will beseen that as the mast swings into upright position its weighted end passes into the'open side of the base and the outer end of the then lowermost tube let is guided into the curved rod 5. As soon as it strikes against said rod the tubular 7 body 30 is moved downward, so that its tongue 32 engages over the rod and the mast is held u pright.

Every part of this tower is preferably of metal, except the weights and the rope, which may be of any desired material. By having the mast tubular, as seen, the pump-rod P of the windmill (when the latter issupported by the mast) may pass downward through the two tubes 1% and be detaehably connected in any suitable manner at its lower end with the pump or other machinery which the mill is to operate, the connection being necessarily a detachable one, in order that it may be disconnected when it is desired to lower the mast. However, this feature I have not described, as it forms no part .of 'the present invention. Such a tubular guide for the pump-rod will prevent it from being swayed in the wind or from exposure to the other elements.

The use and advantage of a tilting tower to support a windmill are too obvious to need elaboration here. By the construction described the base and the mast are each braced against deflection in any direction, the. mast occupying a position at the center of the base and of its braces, which consist of the frame and truss-rods.

I do not describe in detail the manner of connecting the'various members, although it will preferably be by bolts, and I reserve the right to make such changes in theconstruction as may come within the spirit of my invention, one of which will include the sub- .stitution of wood or other material for some of the parts of this device.

\Vhat is claimed as new is- 1. The herein-described tower, the same comprising a skeleton base of rectangular cross-section and with one side open, horizontal bars at the top of said base having oppositely-disposed journal-boxes a shaft having bearings mounted in said boxes, aligned bosses at the center of said shaft, a mast having its center secured in said bosses, a rectangular frame secured to said shaft, and trussrods connecting the ends of the masts and leading over the corners of the frame, as set forth.
