Abstract: 451,120. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., and THOMAS, H., Aden Road, Ponders End, Middlesex.-(Maatschappij van Berkel's Patent Naamlooze Vennootschap, and Berkel, W. A. van; 33, Boezemsingel, Rotterdam, Holland) Feb. 27, 1935, Nos. 6277 and 7643. [Class 28 (ii)] In a slicing-machine having a substanceholder which has a step-by-step feed motion towards the cutting plane, the substance holder is detachable, and an auxiliary substance-support is substituted therefor, across which support the substance is moved towards the cutting plane. In Fig. 2, the usual substance holder, i.e. the feed table has been removed, and the auxiliary support, viz. the trough 30, is attached to the horn 24 which, as is usual, is carried by the under carriage or table 10 and holds the substance against the cutting pressure of the knife. The trough 30 has a slotted lug 34 which is held by a swivel bolt 32 on the horn, whilst at the opposite side of the carriage or table 10, an extension of the trough 30, ending in an inverted channel portion 31, embraces a wall 23 and is locked by a nut 35. The feed is effected by a last slice holder 36 on a bracket 37, which is detachably carried by a feed member 14 actuated by the feed screw 12 and guided by bars 15, 15<a>. The detachable connection is effected by a rib 18 and recess 19 on the member 14 engaging with a recess 20 and projection 21 on the foot 37<a> of the bracket 37, a catch 22 locking the engaged parts together. The feed table is, when in use, attached in a similar manner to the feed member 14. The last slice holder 36 is guided on a bar 38 attached to the trough 30, and is arranged at an inclination to conform with the inclination of the trough 30. In Fig. 3, after removal of the feed table, the top plate of the under carriage 10 is arranged in trough form, thus being rendered possible by forming the top plate in two parts 40, 41 hinged at 42 and having struts 43, 44 to support the plate parts in their raised positions. The struts are under the action of springs 45, 46, and, when the top plate is folded flat, are accommodated in slots 51, 52 and rest on ledges 53, 54. The last slice holder is pivotally mounted at 55 on a bracket 56 so that it may be swung into a position to suit the trough 40, 41 or to suit the flat top plate. The bracket 56 is, as in Fig. 1, (not shown), detachably secured to the feed member 14. In a further modification, a push-pull machine provided with a slice thickness gauge or positioning-abutment plate interconnected with the setting-gear for slice-thickness regulation, is arranged with a detachable feed table, and an auxiliary substance-supporting trough attachable to the under-carriage. The trough has an open bottom to permit the passage of an auxiliary substance carrier which receives some of the weight of the substance and reduces the frictional drag of the trough walls. The auxiliary carrier is attached to the feed member which also carries a pusher which is substantially of triangular formation and is carried on a sleeve which is slidable vertically on closely spaced clamp posts to one side of the trough. The triangular pusher has clamping teeth on one of its sides, and is pivotally secured to its support, so that, by inversion, it may be used as an ordinary clamp when the trough is not in use. The pusher, moreover, has a double face and is carried by a lockable pivoted link from the sleeve, so that by swinging the link the pusher may be given a different operative position in the trough and thus is provided a pushing range longer than the feed screw. The invention is applicable to machines having a stationary undertable.
