Abstract: 12,828. Schoonmaker, G. H. L., Canfield, J. A., and Milburn, H. G. June 24. Automatic-feed weighers.-Relates to hat-forming machines, particularly to improvements in a known form of automatic fur-weighing feed-mechanism in which a scale-pan is fed by two unequal belts, the larger of which is stopped by the action of a pivoted dog when the scale-pan descends with a shortage in weight due to the weight of the dog, the deficiency being finally made up by the smaller belt. A pivoted scale beam 6, Figs. 1 and 2, carries an adjustable weight 7 and a pivoted pan 8 provided with a hinged bottom 9 normally closed by means of springs 10. A hopper 24 provided with doors 25 is fitted with aligned shafts 26, 27 and 28, 29 made in independent unequal lengths held at the inner ends by sleeves and provided with collars to carry the two unequal belts. The shafts 26, 27 are fitted with loose pulleys 36, 37, and fast ratchet-wheels 38, 39 respectively, normally engaged by any frictional device such as spring-cup washers. A power pulley 49 is belted through the medium of a pulley 50 to a pulley 48 on a shaft 44, another pulley 47 which is belted to a pulley 51 on the shaft of the usual paddle-picker, and the pulley 51 is in turn belted to a pulley 53 of a paddle or fan provided for removing surplus fur from the belts. The shaft 44 also carries wheels 45, 46 gearing with wheels 42, 43 on a shaft 39<a> provided with fast pulleys 40, 41 belted to the'pulleys 36, 37. The tail of the pivoted dog 55, Fig. 1, is connected by a rod or wire 57 to a pivoted pawl 56, which is caused to engage the ratchet 38 of the larger belt when the nose of the dog descends with the scalepan, so that the pulley 36 is rendered idle, the larger belt stopped, and the scale beam relieved of the weight of the dog. Fur is still supplied by the smaller belt, and the scale beam finally comes into contact with a pivoted finger 58, Fig. 2, held normally by a pin 59, and completes the circuit of a battery 60 and a magnet 61, adjacent to the latter of which is a pivoted armature 64 carrying a hook 65 which normally holds up the tail of a pawl 62 adapted to stop the ratchet 39 of the smaller belt. Crank arms 78, Figs. 1 and 2, on a shaft 77 geared by a worm shaft 81 and wheels 82, 84 to the wheel 42, are adapted to strike inclines 73 of bell cranks 71 arranged to strike projecting pins 72 on the bottom 9 of the scale-pan to open it. Lugs on the crank 78 are adapted to strike bell cranks 66 connected by studs and slots to rods 70, 76 respectively connected to pins 69, 75 provided on loose dogs and adapted for withdrawing the pawls 62, 56. The fur is delivered on an apron and passes to the usual distributing, blowing, and forming chambers. Means for automatically stopping or continuing the feed on opening and closing the doors of the forming-chamber is shown in Figs. 2 and 5, but is not claimed. The door 4 is fastened to a rod 90 which is hinged to a rod 89 connected to a slide bar 86 provided with an inclined slot 87. A pin 102 projects into the slot 87 and also into an annular groove in a disc 93. This disc is supported in a pivoted journal box 91, and splined on a shaft 95, and provided with a hub adapted to frictionally engage a loose pulley 96 on the shaft. A pulley 99 belted to the power shaft is carried on a shaft 98 geared to the shaft 95, and the pulley 96 is belted to a pulley 103 on the shaft of the upper feed roll of the fur-blowing chamber.
