Filed: 1933-12-07
Abstract: 419,988. Mincing-machines. WARD, Ltd., T. W., and ELLIOTT, F., Savile Street, Sheffield. Dec. 7, 1933, No. 34375. [Class 28 (ii).] In a meat chopping or mincing machine, the knives are spaced and carried by washers or carriers which are keyed or connected together in such manner that when the knives are disassembled and re-assembled on the knife shaft, the angular relationship of the knives cannot be disturbed. As shown, the knife shaft 7 has a collar 8 into which two screws 9, 10 are threaded, the heads of the screws projecting from the collar 8 to engage holes 29, 30 in the washer or carrier 16. The knife 13 is screwed to the face of the carrier 16 by screws, similar to the screws 9, 10, the heads of which engage holes in the carrier 15 which in turn has the blade 12 secured to it, and so on. The final screws 17, 18 are accommodated in recesses or apertures in a ring 43 which is clamped by a nut 46 to secure the whole assembly of knives 11-13 and carriers 14-16. The shanks of the knives, as shown in Fig. V, embrace the shaft 7 and are slotted at 31, 32 to permit radial adjustments of the knives to compensate for recession of the edge due to wear. To prevent the carriers and knives from being assembled with incorrect relative angular positions, the screws 9, 10 &c. and the corresponding holes 29, 30 &c. may be arranged otherwise than on a diameter, or one set of screw heads and the corresponding holes may be made of different size to the other set of heads and holes. As shown, however, the correct angular relationship is assured by arranging one set of screw heads and the corresponding holes at a different radial distance from the axis than the other set of heads and holes. The carriers 14-16 are spigoted and socketed to engage with one another.

Abstract: 169,647. Kovßcs, T. Dec. 8, 1920. Reservoir pens.- A drawing-pen nib, more particularly for use with reservoir pens, has a sectorshaped shank and is unsplit, but perforated through the shank so that the ink may pass to the outer surface, from whence it is fed by capillary means to the point. The nib f is shown in Fig. 1 as attached to the lower part a of a reservoir by means of a ring b, a projection f<2> on the nib entering an annular recess a<1> in the reservoir body to prevent axial displacement. The feed member c which terminates in an outlet orifice a is fitted into the lower end of the reservoir. The nib is perforated at e and f<3> for the passage of ink and air respectively, the air entering the reservoir through an opening c<1>, which may form a continuation of the orifice d in the feed member. A covering- member g is clipped on to the nib, and is spaced therefrom by projections g<1>, g<2> to provide a capillary space i along which the ink is fed. The member g is bent away from the nib at g<3> to uncover the air-hole f'. The point of the nib may be notched to prevent the nib from squeezing the ink before it, and the lateral edges f<4> may be bent at right-angles to prevent leakage at the sides and to serve as lineal guiding-means. In the modification illustrated in Fig. 5, adapted to produce block characters, the nib is provided with a disc-like writing-portion f<5> disposed at an angle to the shank and formed with notches f<6> and a perforation f<7> to allow the ink to flow back to the inner surface. The cover-plate is shaped to fit the portion f<5>, and a guide f<8> may be formed on the nib. In a further modification. the nib is provided with a tubular writing-portion forming a capillary channel, or a pin may be introduced therein to provide the necessary capillarity.
