ANTI -FRICTIONAL CHOCK OR LEADERa SPECIFICATION forming part of Letters Patent No. 381,831, dated April 24,1888.
Application filed January 30, 1888. Serial No. 262,381. (No model.)
bridge, in the county of Washington and State of Maine, have invented certain new and useful Improvements in Anti-Frictional Chocks or Leaders; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of one end of a spar provided with my improved leader. Fig. 2 is a vertical transverse sectional view of the same, and Fig. 3 is a detail view of frame and guide-pulleys. v
The same numerals of reference indicate corresponding parts in all the figures.
My invention has relation to anti-friction leaders or checks for booms, gaffs, or other spars of a vessel, having a pivoted frame provided with guide-pulleys for the rope to be carried around the leader; and it consists in the improved construction and combination of parts of such a leader, in which the sheave is journaled in a cleat or bracket upon the side of the spar, as hereinafter more fully described and claimed.
In the accompanying drawings, the numeral 1 indicates the spar, to one side of which the cleat .2 is secured by means of nutted bolts 3 passing through the ends of the cleat and the spar, and the inner side of this cleat is formed with a recess, 4, extending from the upper to the lower edge of the cleat, leaving the ends of the cleat in contact with the spar and a space between the cleat and the spur at the middle of the same.
The cleat is formed with the usual slot, 5, in which the sheave 6 isjournaled upon the pin 7, and the ends of this pin project through the sides of the cleat, and have the inner ends of the bent arms of the frame 8 for the guidepulleys 9 pivoted upon them, the said frame having one arm upon the outer side of the cleat, and the other in the space formed by the recess of the cleat, the arms straddling the re cessed middle of the cleat. The rope 10, which is fastened to the sail 11, passes between the guide-pulleys and around the sheave in the cleat, from which it is carried to its further destination wherever the character of the rope and its office requires it.
It will be seen that this leader will perform the same function as the leader or chock for which Letters Patent were issued to me on the 11th day of May, 1886, No. 341,838, and the leader or chock for which I have made application for Letters Patent on the 5th day of August, 1887, Serial No. 246,195; but in both of these cases the spar was slotted for the reception of the sheave and for the passage of the rope, while in this leader the sheave is journaled in the cleat, which is secured to the side of the spar, so that there will be no weakening of the spar by slotting it.
The frame for the guide-pulleys will swing freely upon the pin of the sheave, and the entire cleat and sheave and frame may be secured upon the spar by simply passing the nutted bolts through the spar and securing them in the perforations in the ends of the cleat.
Having thus described my invention, I claim and desire to secure by Letters Patent of the United States In an anti-friction leader for the rigging of vessels, the combination, with a cleat, the inner side of which is provided with a recess extending from its outer to its inner edge, and having a slot, a sheave in the slot, a pin through the leader and through the sheave, and a frame secured uponthe pin, with one of its arms within the recess and the other arm upon the outside of the cleat, and'having guide-pulleys journaled in the other end of the frame.
In testimony that I claim the foregoing as my own I have hereunto afiixed my signature in presence of two witnesses.
