Abstract: 14,723. Boult, A. J., [United Shoe Machinery Co.]. July 1. Nailing.-Relates to mechanism for assorting or arranging nails, whereby nails may be delivered to the holes of a nail-plate or templet either all head first or all point first. In the arrangement shown in Figs. 2 and 4, an inclined table A, provided with raceways a for the nails, is mounted upon a frame A', to which a shaking movement is imparted. At the foot of the table A is arranged a lilting-device B, mounted on a spring-controlled rod actuated by a cam B<4>. In front of the device B is a bar carrying an adjustable plate or nail gauge c. The gauge c, the bar, and the device B are all formed with grooves in register with the raceways a in the table. Below the gauge c are placed pockets c<2> leading to the delivery tubes f Over the pockets is arranged an arresting and reversing device consisting of two plates D, D' connected together, so as to allow a certain relative motion, by spring- controlled brackets D' taking over bolts D<3> provided with nuts Dx. A pin mounted on one arm of a bell-crank lever d<3> engages a slot in each plate D<1>. The levers d<3> are connected by a link d<7>, and are operated by a lever e coupled to a link e<2> mounted on a rooking shaft e<3> oscillated by means of an eccentric e<6>. An arm on the lever e engages a slot in a plate f<3> provided with holes corresponding to the pockets c<3>, and arranged to slide between the pockets and a bar f provided with delivery holes in which the tubes f are secured. In operation, the nails pass down the grooves in the table a, and are received on the device B when in its lowered position. When the part B rises, the nails slide on to the gauge c and against the face of the arrester. The gauge is so adjusted that the gap between it and the arrester is substantially half the length of a nail. Any nail passing head first against the arrester will overbalance, and fall by gravity into the pocket c<3> and rest on the slide f<3>. A nail delivered point first against the upper plate D<1> of the arrester is reversed in the following manner :-The upper plate D<1> begins to move, owing to the motion of the eccentric e<6>, and the point of the nail slides on the plate D. When the bracket D<4> comes against the nut D<x> on the bolt D<3>, the two plates D, D<1> move together, and the head of the nail slips off the gauge e, and is delivered so as to rest head first on the slide f <3>. The slide f<3> is now moved by the lever e so as to bring the holes therein in register with the pockets, and the nails drop down the delivery tube f<7> to the nail-plate &c. In another arrangement, shown in Figs. 6, 7, and 8, the table, lifter f, and gauge are substantially the same as above described. The pockets C' are each provided with two feeding-mouths, C, C<1>, above which is arranged the arrester A of cylindrical shape. The arrester is provided with grooves a corresponding to the guide-grooves in the table &c., and a gate a<1> is arranged to slide therein so as to bring openings into or out of register with the grooves a. A gear-wheel D, adjustably secured to the journal of the arrester, engages a quadrant D' on one arm of a lever D<2>, the other arm of the lever being fitted with a roller &c. in engagement with a cam D<4> on a shaft e<2>. To a hanger E, depending from the frame of the machine, is pivoted a lever E<2> provided with a pin for engaging the inclined end of a lever E<4>. This lever E<4> is connected to a rod which operates a spring-controlled stud attached to the gate a<1>, when the lever E' is raised, for the purpose of moving the gate. At the same time a pin f x on the lever E<8> releases an arm from engagement with a stud on a collar f<3> adjustably secured to the shaft e', and allows a spring f<4> to move the shaft so as to bring a clutch member e<1> thereon into engagement with a clutch member on a driving-shaft. In operation, the nails delivered against the arrester head first fall by gravity down the mouth C<1> to the pocket C<2>. The nails delivered point first are stopped with the points abutting against the gate a'. The lever E' is then lifted, and the shaft e' put into gear with the driving-shaft. The gate is moved so as to bring the notches into line with the grooves in the arrester, and the nails pass through the openings. The arrester is rotated so as to allow the nails to slide thereon, and then rotates in the opposite direction and delivers the nails head first into the pocket C'. In order to deliver the nails point first, the collar f and the arrester A are suitably adjusted so that the nails may be delivered point first into the mouth C and pass from there to the pocket C'.
