E are In the drawing, the letter A designates a the carriers, which are secured to the ends frame, made of wood or any other suitable wt of the carrying-heads E by means of screws terial, of sufiicient strength and durability to f. (See Figs. 3 and 4.) The heads E are support the working parts of this machine. mounted on the shaft f, and they are so arf they are moved are held'firmlyin position while the cutters act. The shaft on which are mounted the heads Eandcarriers E, receives its motion by means of a belt, G, which extends from a pulley, h, on the driving-shaft k over a pulley, 72 on an arbor, extending across the frame A in front of the hopper-box and over the carrying-heads, and from this pulley said belt extends round the carrying-heads E and over a pulley, h back to the pulley h. (See Fig. 1.) The pulleys h and h are so situated, in relation to the carrying heads E, that the belt G embraces a considerable portion of said heads and imparts to them" the desired motion, while at the same time said belt presses the pencils down into the sockets of the carriers and retains them while their ends are cut ofi', and,after the cuttingoperation has been accomplished, the pencils drop on the belt G and chute H, from which they drop intoa suitable box or receptacle. A slide, 1', serves to shut off the discharge from the chute while the receivingbox is changed. The arbor of the roller h has its bearings in boxes h, to which a sliding motion can be imparted by screws k Figs. 1 and 3, so that the tension of the belt G can be regulated.
The operation of cutting the pencils is effectc- '1 either by the smooth-edged cutters I, or by the circular saws I, illustrated in Fig. 6. Said cutters are mounted on an arbor, j, which has its hearings in suitable brackets secured to the frame A. The cutting-edges of these cutters are held in close contact with the outer surfaces of the carriers E by means of springs j, of India rubber or other suitable material, and the carriers are made of steel and hardened, the outer edges of the sockets f in said carriers being left sharp, so that the operation of cuttingis efl'ected between the cutting-edges of the cutters and the sharp edges of the sockets of the carriers. The cutters I are by pret crence made concave, so that the wood or cuttings from the pencils have room to. discharge, and that the ends of the wood are prevented from getting soiled by the cuttings of the lead.
The cutting-edges of the cutters, which are liable to become dull by the lead of the pencils, are continually sharpened by the action of grinding-stones or emery-wheels J, which are mounted on the ends of arbors k that have their bearings in frames 7:, to which an oscil lating motion is imparted by rods k, extendin g from eccentric wrist-pins k, which project from disks secured to the ends of the shaft f of the carrying-heads. By the oscillating motion of the frames 70 the faces of the stones are continually drawn of the cutters, and by this motion the opera tion of sharpening the cutting-edges is facilitated, and at the same time the faces of the grinding-stones or em cry-wheels are kept level and prevented from wearing uneven. The burrs raised at the cutting-edges on the inner sides of the cutters are stripped off by contact with the harden-ed faces of the carriers E. a The arbors k are so arranged in the oscillating ranged that they can be adjusted further apart or closer together, to suit pencils of difi'erent length. In order to eifect this purpose said heads are mounted on the shaft f -so that they can move on it in the direction of its axis, and they connect, by set-screws f,,with a disk, f which is firmly keyed or otherwise fastened on the shaft f so that by turning the set-screw the heads E can be moved from or tOWEl-Il? cach'other, may be desired. It is obvious, however, that the object of adjusting the heads on the shaft f can be accomplished in many didercnt ways-such, for instance, as a screwthread and nuts on the shaft f itself, or setscrews passing through the heads themselves; but it is of great importance to adjust the heads exactly at the proper distance apart, for if 21. projects too much when acted on by the it is liable to split, and the heads ought adjusted so that the ends Ofthe pencils do not project beyond the carriers more than the thickness of a sheet of paper, or just enn slice and impart to the ends of the pencil the desired finish. The carriers E are furnished-with socketsf to receive the pencils, said sockets being made to receive either round, hexagonal, ,or octagonal pencils, (see Fig. 5,) and diiferent sets of carriers are provided to receive pencils of different thickness. From one side of each of these sockets projects a scraper, f which is intended to scrape out the pencil supported by the hooks e of the guideplates D at the moment it passes the same, and to cause said pencil to drop into the socket. Each pencil, on being throwr out of the hooks e, strikes the fingers c and wipers e whereby it is compelled to drop down into the sockets, while said wipers also prevent two pencils from lodgin g simultuneousl y in the same socket. After the pencils have been deposited in the socket successively between two gages, F F, which extend from the rear cross bar 9 of the frame A. These gages are made in the form of springs, and they bear against the ends of the pencils passing between them, the power with which they press against the pencils being regulated by means of set-screws (See Fig. 2.) By the action of these gages the pencils are brought into the required position in relation to the carriers, the ends of each pencil being made to protrude the proper distance beyond the carriers, and in order to make allowance for any small variation ex-. isting in the length of the difierent pencils, one of the gages F is allowed to yield without llfillt, while the other gage F can only reccde until it strikes a bracket, 9 which is so adjusted that the end of the pencil on that side will extend beyond the carrier the exact dis tance required, while the opposite end of the pencil may extend beyond the carrier a little more or a little less, according to its length. By adjusting the bracket 9 the quantity to becut ofi'on each end of the pencil can be evenly divided, and, by the action of the gages bearin against the cuds e-f tho pencils, said pencils are carried into the across the beveled faces frames i can essnme a siialing mo 1 ing hcgzgiee-hcx conch-carrier, E, provided tionm the dlrecticn of t rlength, spiings 1 with s cm-t f tc i'eeeive the pencils from the s k, acting on ehe backs of the stones 01? wheels hopper emit to expose them in succession to the J,keep the grnsling serfcces continually 1 he ection oi the cutter I, substantially as set forth. their work; A rotary motion is imparted to 'ihe elastic fingers OIWipGlS at the bottom the grinding-wheels by means of belts $0 of thehocpcnhossin eomhinetionwiththemov: tending from suitable pulleys en the driving;- ing carriers, substantially as and for the punshaft ever pulleys k on the ends of the a-r'hors pose clescrlbefi.
