srncmicarrou forming part of Letters Patent No. 787,118, dated August 25, 1903.
Application illedlpril 9, 1908. Serial No. 15am. (No model.)
To all whomit may concern: I
Be it known that I, Tnomas S. LAUGHLIN, a citizen of the United States of America, and a. resident of Portland, Cumberland county, 5 State of Maine, have invented certain new .and useful Improvements in Fastening Devices'for Booms, of which the following is a specification. I v l My invention relates toa device for fastening the booms of yachts-and other vessels to their masts,
Hitherto this has been commonly done bymeans of a band which was made in; one piece with an eye orsocket on the rearward side to receive the pintle-to-which the end of the boom was secured and by means of which it was pivoted. The ends of the band were fastened together forward ofthe mast by means of a bolt.
' this connecting device that it will be-just as strong and durable as the old device and it may be more cheaply and perfectly finished and more easily and quickly applied and removed. 1 j
7 According to my invention I form the band in two halves, which may be formed by the drop-forging process, and the socket for the pintle I form on a bracket, which is confined ,30 between theendsof the half-bands by the bolt which holds them together. The bracket has a projection extending, downward by 1 which it may be secured, to the mast.
bracket is formeda socket, in which fits the pintle g, secured in place by a pin 9. upper end of the 'pintle ispivoted the screw e, which is adapted to enter the end of the boom. In-addition to the screw c there is The object of my invention is to so form" I illustrate my invention by means of the to be secured by a screw or other fastening means to the mast. On the outer end of the To the pivoted to the'pintle the shackle d. The belt f passes through the shackle, the screw, and the upper end-of the pintle. It will be seen that these parts may all be made by the d'rop- 55 forging process, and. this'may be more perfectly formed and finished than if the old 1bang were used, which had to be forged by The entiredevice is easily put together, 6o
very strong, and adapted to be made by a drop-forging'process.
Iclaimv 1. The herein-described device for fastening a boom to a mast, consisting of a pair of .65 f
half-bands bolted together around the mast, a bracket confined between the two ends having a downward-extending projection adapted to be fastened to the mast, the outer end of said bracket being provided-with a socket, a vertical pintle fitting said socket, a screw or bolt adapted to enter the endof the boom and a shackle both pivoted to the upper end of said pintle by means of a'bolt.
2. The herein-described device forfastening a boom to the mast, comprising a pair of semicircular bands, each provided with op-V positely-extendingeyed lugs upon their ends, bolts removably securing said bands around the mast entering said eyes, a bracket mounted upoii the forward bolt between the adja- I cent lugs of the bands and having a downwardly-projecting lug provided with an eye adapted to contact the mast, ascrew entering said eye to secure the lug to the mast, said bracket also being provided upon its forward end with a vertical socket, a pintle pivotally mounted within said socket and an eyed lug projectingfrom the upper end thereof, escrow adapted to enter the end of the" boom having eyed portions, a shackle having eyed portions, and abolt adapted to pass through the eyed lugs of the pintle and the eyed portions of the screw and shacklefor securing the shackle-and boom carrying the 5- screw to the pintle. 1
