MOORING MEANS Application led March 3,

To all whom it may concern Be it known that I, EMANUEL SALoMoN ULLMANN, a citizen ot the United States, residing in the borough of lManhattan, city and State of New York, have invented certain new and useful Improvements in Mooring Means for Dirigibles, of which the following is a specification.

The invention relates to mooring means for dirigibles, or any form of lighter than aircraft.

The principal object is to lprovide a simple and cheap means of mooring the smaller types of privately owned Sport cra tt.

further object to provide a moorinnY means that will be comparatively light in itself, but stayed in all directions to which a stress may be delivered, and at the same time, to present a sector of 90O each side of the suspension or mooring point thatwill be free of stays or lines that would be liable to cause chate or injury to the vessel moored.

A further object is to provide a mooring means consisting oi a vertically disposed mast or upright, the same being suit-ably stayed in a sector of not over 180, the said stays being revolubly mounted in a manner to cause them to follow the line of stress and always maintain their center of veffort diametrically opposite the said line of stress or point of suspension of the craft to be moored.

The old form of staying a. mast with tour or more stays, the same being'equally disposed and fxedly secured over 360o would be unsuitable for this form ot mooring. due to the danger of the stays injuring the craft when swinging in the wind or lowering to the ground. y

With these and other objects in view, the invention resides in the Various novel parts and devices combined, arranged, operated and co-operated as hereinafter described and claimed. A

In the accompanying drawings, in which like reference characters indicate correspending parts, and in which I have illustrated one embodiment of my invention:

Fig, 1 is a side elevation of the arrange ment. A

Fig. 2 isfan enlarged view of a travelling stay trolley in which a section of the supporting track and the anchorage means for the same are shown.

Fig.4 3 is a plan view of Fig. 2,

Specification of Letters Patent.

FOR DIRIGIBLES.

Patented Apr. 25, 1922.

1921. Serial No. 449,377V

Fig. 4 is a view looking downwardly and 'l'firrwardly on4 the mooring arrangement from the point of staying.

Fig. 5 is a sectional elevation of an eularged view of the upper portion of the mast.

The form of .my invention I am about to describe is the present preferred form. I do not wish to limit myself', however, to this specific form, its pro-portions, sizes or ma terials; in fact, I reserve the right to make departures in the details here shown to meet rthe demands of commercial lpractice so long as I do not depart from the broad spirit of the invention as set Vforth in the annexed claims.

In the embodiment oil the. improvement here shown, .A indicates a mast or upright of any desired height or diameter, suitably embedded in concrete or other approved mixture B. The mast isfurther titted'at its Ytree end with a Y arm C, a thrust collar D, a ball race E. and a sheave head F, The Y arm (l is revolubly mounted upon the thrust collar D and under certain conditions free to be lowered or raised .to any point of the mast between the point of its present disposition and the base. The said Y arm is further itted with stay eves G and supporting eyes H and a bell muouth end I, the

- and F2 are fitted with `guide cheeks F4 and F5. Sheave F3 has a Hare mouth bill guide F", the purpose of which to be hereinafter described. Raised a suitable distance Jfrom the ground and supported by any means such as rods K, is disposed a circular track or support Il, the center of which being the vertical center ot the mast. While for convenience I have shown the track with a rectangular cross section, obviously it may be a slot or any desired conventional form. Loosely mounted upon this track I will dispose any suitable number of stay sheaves M. In this form I have indicated three, and two sitter sheaves N, all five sheaves being disposed about equal distance apart and or near the base of the said mast or spar, trolleys mounted under the said runway, a slidably and revoiubly mounted cross arm mounted upon the said mast or spar, a revoluble support Alor the said cross arm, stays disposed between and secured to the said cross Varm and the said trolleys and means for rotating the said stays horizontally as the said cross arm is horizontally rotated.

7. ln a mast support, the combination of a ,'ertical mast or spar, a horizontal circular runway disposed around the mast and equal distance therefrom, the same being at or near the base of the mast, anchoring means for the said runway, a plurality of trolleys mounted under the said runway, the same being disposed substantially equal distance apart over 1.800 of the said runway and rigid securing means for holding the trolleys in fixed relation to each other, a slidably and rerolubly mountedr Y cross arm mounted upon the said mast, a revoluble support `t'or the said Y arm, adjustable connecting means between the said Y arm and the revoluble support. a back stay and side stays disposed between the said Y arm and the staytrolleys, cross shifter stays disposed between the diverging Y arms ot the cross arm and the shifter trolleys, all as and for the purpose described.

8. ln mast support, the combination of a vertical mast or spar, a horizontal. circular runway disposed around the mast and equal distance therefrom, the same being at or near the base of the mast, anchoring means for the said runway, a plurality of trolleys mounted under the said runway, the trolley having' double flanged wheels under the runway and plain back lash wheels over the runway, a connecting arm between the wheels,

two extension lugs for securing a connecting means between the trolleys and a stay eye, a slidably and revolubly mounted Y cross arm mounted upon the said mast, a revolube support for the said Y arm, adjustable connecting means between the said Y arm and the revoluble support, a back stay and two side stays disposed between the said Y Varm and the stay trolleys, cross shifter stays disposed between the diyerging arms of the Y arm and the shifter trolleys, rigid connecting means between each trolley and turnbuckle in each stay.

9. In a mast support, the combination of a vertically disposed mast or spar, a slidably and revolubly mounted Y cross arm mounted upon the mast or spar, a sheave head hanger for the same, a ball bearing support for the slieave head, a support for the ball race, two single sheaves and one double sheave in. the shea ve head hanger, a flexible and adjustable connecting means secured to the Y cross arm, the same passing over the sheaves in the slieave head, the `tree ends of the flexible means being secured. to the movable trolley structure; side and back stays for the mast, a revoluble trolley structure for carrying the side and back stays, means for automatically shifting horizontally the trolley structure so that its center of effort will remain diametrically opposite the single leg of the Y arm, the latter adapted to shift horizontally; a mooring` line in the single leg of the Y arm and a fairleader sheave, all as and for the purpose described.

In testimony whereof, I have signed my name to this specification, this 21st day of February, 1921.

EMANUEL SALOMON ULLMANN.
