WlNDMlLL-DERRICK.
SPECIFICATION forming part of Letters Patent No. 431,991 dated July 8, 1890.
Application filed May 2, 1890. Serial No. 350,388. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS O. PERRY, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful WVindmill-Derrick, of which the following is a specification.
My invention relates toimprovements in a windmill-derrick, (for which I have obtained LettersPatentof theUnitedStates No. 37 5,378, hearing date December 27, 1887,) and the object of my improvements is to provide for supporting a windmill on a trussed mast pivoted on a base of such construction that the trussing of the mast will not interfere with turning the mast on its pivot, as required, for bringing the wind-wheel down to the ground. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side View of the derrick with windmill attached to the pivoted mast. Fig. 2 is a front View of the derrick. Fig. 3 is an elevation showing the bracing of the pivoted mast, looking squarely at one side. Fig. 4 is aplan of the derrick. Fig. 5 is asectional plan showing the lock, lock-timbers, and sect-ions of the fulcrum-posts cut off just above the lock-timbers. Fig. 6 is an enlarged plan of the mast-lock. Fig. 7 is a side View of the lock-key enlarged.
Similar letters refer to similar parts throughout the several views.
M is a rectangular mast pivoted near the center of its length on top of a supportingbase and carrying a windmill A at its upper end. A reciprocating rod or revolving shaft R, actuated by the windmill, lies along one corner of the mast, to which it is attached by means of suitable guides or bearings h. The rod or shaft R serves for transmitting the power of the wind-wheel to driven machinery below. The pivot is formed by bolting to the front corner of the mast M a pivot-casting X, with trunnions on opposite sides. The axis of the pivot is perpendicular to a plane containing the front corner of the mast and intersecting the right angle formed by the two adjacent sides, and is placed preferably far enough to the rear of the front corner of the mast, so that the pivot-casting X will not interfere with the shaft R lying close against the corner. The trunnions of the pivot-easting X are fulcrumed either directly in the tops of the fulcrum-posts or in two fulcrum irons F F, bolted to the tops of the fulcrum posts G G II II, and joining them together in pairs G G and III-I. These pairs of fulcrumposts diverge from each other as they extend down toward the ground, and the posts in each pair also diverge from the fulcrum-iron uniting them, and are anchored to the ground in a line perpendicularto the direction of the axis of the mast-pivot. The four fulcrumposts taken together form a rectangular pyramidal fulcrum-supporting base. The fulcrum-posts so diverge with reference to each other that the vertical projections of any two adjacent posts form a right angle with each other, as shown in Fig. i.
A few feet above the ground two lock-timbers N and N, united at their intersection with each other, join diagonally-opposite f ulcruel-posts G II and G H. Tie-boards O O 0" tie the fulcrum-posts. together on three sides of the base, leaving the rear side open between the posts G and H, so as not to interfere with the swinging of the pivoted mast M. The lock-timbers N'N' are most conven-- iently secured by nailing the tie-boards O O O" to their ends where they adjoin the fill crum-posts, and are so placed that they intersect and join each other just back of the lower end of the mast, so as to make a convenient support for the mast-lock L L E.
Neither tie-boards nor braces are admissible between the rear posts G and II, as they would interfere with swinging the mast fromits Vertical position about its pivot, as required, for bringing the wind-wheel down to the ground; but on the remaining three sides of the base the fulcrum-posts may be tied together and braced at intervals, as desired, since the wind-wheel can be brought down to the ground by tilting the mast, as indicated by the dotted lines in Fig. 1, where it will be noticed that the position of the tilted mast does not interfere with uniting the front fulcrum-posts G and II by bracing or boarding from top to bottom. The two lock-timbers N N, fastened together at their intersection in conjunction with the three tie-boards O O 0, make it unnecessary to unite the posts G and II with a fourth tie-board.
Other pairs of timbers similar to the locktimbersN N, in conjunction with correspond ICC ing tie-boards, may unite the four fulcrumposts at any desired number of vertical intervals, and thus give rigidity to the two rear fulcrum-posts, which cannot be directly connected. The shape and position of the trussed mast also admits of direct ties and braces between diagonally-opposite f ulcruin-posts, and the lock-timbers, with others similarly placed above, would make a part of such a system of bracing.
The mast-lock consists of a stop L, bolted securely to both lock-timbers N N at their intersection, and a clamp L, hinged at one end to one side of the stop L, while the other end of the clamp is slotted to receive the projecting end of the other side of the stop, also slotted, to receive a wed ge-shaped key I, back of the clamp, to hold it pressed against the back corner of the mast when inclosed by the lock. The stop L is provided with two faces, which rest against the two adjacentfront sides of the mast, leaving a clear space around the front corner of the mast for the uninterrupted passage of the shaft R.
To stiffen the pivoted mast M, two sets of braces D and D are applied to the two adjacent rear faces, so that the bracing stands out from the mast in two directions at right angles with each other, as shown in Fig. 4, where it will be seen that a vertical projection of the mast with its two sets of bracing just fits the angle formed between the vertical projections of the fulcrum-posts G and H. The braces D form a triangle with the mast M, as a base to which they are directly joined at their outer ends at some distance from each end of the mast, so that they may not interfere with the wind-wheel at the top and may leave room for attaching counter-weight and mast-lock at the bottom. At the apex of the braces D their inner ends are joined securely together, and are also connected by a rigid tie-bar Y to the mast. The braces D, as well as the bar Y, are made to resist either tensile or compressive strains. What has been said of braces D and tie-bar Y applies also to braces D and tie-bar Y. Thus the mast is a common member of two trusses, which hold it from bending under strains applied from any direction. Thetie-bars Y and Y should take hold of the mast at or near the pivotcasting X. A mast trussed in this way need not be rigid in itself where it joins the pivotcasting X, but may be made of two pieces simply tied together by spiking two pieces of plank V and V across the joint. A counterweight W is attached to the foot of the mast and is made to project some distance in front of the mast-pivot, so as to counterbalance the weight of the trusses behind the pivot. In this way the trussed mast and windmill may be perfectly balanced in any position while swinging about the pivot.
What I claim, and desire to secure by Letters Patent, is
1. In a windmillderrick, in combination with a mast pivoted between two fulcrums sustained by fourfulcrum-posts forming the corners of a rectangular pyramidal base, two lock-timbers connecting diagonally-opposite corners of said base, anda mast-lock attached to said lock-timbers at their intersection, whereby the said pivoted mast is secured in a vertical position or released, so that it may swing on its pivot, substantially as herein set forth.
