It is manufactured bv the Walton Self- Locking Block Co., 404 Atlantic avenue, Boston, and is patented Owners of the in the United tates and European countries. patents claim it is the great- est improvement of the cen- tury in tackle blocks. The blocks are made of wood, iron or bronze and resemble the or- dinary tackle blocks. Two views, one showing the block working horizontally and the other with weight attached, are presented. Among numerous claims for these self-locking blocks made by the Boston manufacturers are the following: "They will stop and lock automatically wherever needed, and can be used at any height. They will also work upside down, horizontally or at any angle. It is impossible for the rope, wire, or chain to slip when locked, and no lever or trigger-rope attachment is necessary or used. Only one rope or chain is used in hoisting or low- ering. Any kind of rope, also chain or wire rope suitable to the size of block, may be used when desired. A pull on the hauling rope immedi- ately releases the lock, and it is im- possible for the rope to jam or chafe. 'There is ncthing to get out of order. The device may be adapted to any size, single, double, triple, four-fold and five-fold blocks, thereby creating more uses for tackle blocks than were ever known before. Overhead tracks and trolleys can be fitted for easy handling of all heavy weights. By the use of the block one may hold all he can pull, as the rope can be locked at will, thus taking all the strain off the arms and giving the user an opportunity to rest whenever needed." Uses to which the blocks may be applied on yachts and vessels are tackles and leaders on deck, check blocks, davit tackles, throat and peak halyards; also in bridge and house f WH, building, on aerial trolleys, in rail- he 'hema ) road service and in quarries, by lum- Wa Coal Cg vA bermen, warehousemen, farmers, Vi ft N My = teamsters, painters and masons, jin ALR oR foundries: and mines, in life saving as SSS ee ji service, in machine shops, for stage \ i scenery and by circuses, in breweries, a | wells, stables, harness rooms, tanner- } ies, slaughter houses, plantations, on fire escapes and by fire departments, for stretching wires and ropes of all ee k'nds, on elevators, awnings, tents, HH i etc. etc. 'Lhe special claim is that ! no tying or fastening of the rope or h q iN \ i Hi | chain to a cleat is needed.
