HUGO REGKMANN, 0F ALToivA-oN-THE-ELBE, GERMANY.
sLInINoA nevica ron SAILS.
Application led November 19, 1925, Serial This invention relates to a sliding device for the sails of sailing vessels on the mast as 'Well on the main and boom and in which riOid guide bars for the movable slides are used which have loosely rotatable fixing bolts for the sail. The invention is characterized in that on the ends of the movable slides pairs of levers are hingedly fixed, Which are connected at their free ends by a pin traversing also the thimble of'the sail, an( several pins being secured against accidental detachment by a safety lever which engages With a groove inthe outer end of the pin.
An embodiment of the invention is shown, by Tray of example, in the accompanying danfing in which y Fig'. l shows in side elevation the arrangen'ient of the sliding device on a mast.
Fig. 2 is a front elevation partly in secdof a portion of Fig. l on larger scale. A g. 3 is a side elevation of Fig. 2.
Fig. l is a cross section of Fig. 3. rlie sliding device for sails according tol e th invention. designed for the mast, consists of a guide bar fixed on or embedded in the mast a and designed to receive the slides c. Each slide c comprises a rotatable vertical bolt (Z having eyes one at the upper end and one at the lower end, to which the sail is attached. Each bolt l has further an upper and a loiver collar g serving as abutments for the bolt Z so that the sail can freely turn With regard to the slide Without any friction on the same. Each slide c is guided in the guide bar Z) by means of tivo transverse pinsl c of circular cross section so that the frictional sliding faces are reduced as much as possible.
G fing' to the rotatable bolts d the sail can swing easily in lateral directions.
'lhe improved sliding device can be used for top sails as Well as for main sails. A technical advance obtained by the improved sliding device for sails is that the interval between the edge of the sail and the mast is smaller than'it can be with any devices of known typo. By this narrow interval No. 70,038, and in France October 16, 1925.
between sail and mast the best possible effect of the sail is obtained, the Wind being' utilized in the best possible manner.
For top sails the guide bar o is fixed on the mast and for main sails it is sunk in the mast so that the jaw of the gaft' can freely move up and down on the mast. In each eye f of the rotatable bolt d a pair of levers z, is pivotally mounted. The edge of the sail is inserted between the free ends of each pair of levers h whereupon a bolt z' is inserted through the eyes in the free ends of said levers and through the correspond ing thimble /c'of the sail. The end of bolt 2 has a groove Z designed to receive a safety lever m pivotally mounted on the corresponding lever It, so that accidental dropping out of bolt z' is prevented. For reefing the sail the corresponding safety levers m have to be unhooked and the corresponding bolts z' removed, this. being carried out rapidly. The sail can be re-attached very rapidly. In order to prevent the bolts z' slipping out of the lever /L when the safety lever m is released the bolt has a projecting rib n engaging a rib or flange on the lever L.
I claim A sliding device for sails of sailing vessels on mast, boom and gait comprising in combination With a guide rail on the mast, boom or gaif, slides loosely guided in said guide rail, a rotatable bolt in each slide, a pair of levers pivotally mounted on the upper end of each rotatable bolt, and a pair of levers pivotally mounted on the lower end of each rotatable bolt said levers having each a hole near the free end, and bolts having each a groove in the foot end said bolts being each inserted through the holes of one pair of levers and through the corresponding thimblel of the sail, and a safety lever pivotally mounted on the outer side of the corresponding lever of each pair of leversl to engage with said groove in said bolt after the same has been inserted to securely lock the bolt in position.
In testimony whereof I aflix my signature.
