Title: Improved machines for cutting confectionery and the like after moulding
IPC: A23G7/00

Abstract: 392,996. Cutting toffee &c. PARKER'S, Ltd. and LOCKWOOD, T., Welbeck Road, Newcastle-on-Tyne. Dec. 21, 1931, No. 35339. [Class 87 (ii).] Toffee and like sweetmeat is cut longitudinally and transversely simultaneously into pieces while on the spreading table on which it is deposited from the boiler by cutting- mechanisms mounted on a travelling-carriage which moves over the stationary table. The table is furnished with racks 2 of which the upper portions serve as rails to accommodate the wheels 6 of the travelling cutting- carriage secured by shoes 7 against tilting. In operation, the rotation of the handle shaft 9 performs four functions as follows: (1) It traverses the apparatus as a whole along the racks 2 through the medium of the gearing 11, 12, 16, the pinion 16 being fixable in either an engaged or disengaged position by the handle 17 controlling the eccentric bearings 14. (2) It drives the rotary-disc knives 21 for dividing the material into strips through the medium of gearing 22, 24, 25. (3) It lowers the spring- retracted guillotine knife 31 for cutting the strips transversely, through the medium of the pivoted lever 36 operated by a cam 42, and (4) It moves the blade 31 longitudinally during the cutting-stroke against the action of the spring 54, to compensate for the travel of the material and ensure a vertical cut by means of the bell-crank 48 operated by the cam 53. The whole of these functions take place in timed relation, as the carriage is moved from left to right along the spreading table as shown in the Figure. The knives 21 are set to varying heights by rotating the bearings 28 about pins 29 and are fixed in the adjusted position by one horizontal and one vertical set screw 61, 64 respectively at each end of the shaft. To put the transverse cutting mechanism out of action when not required, the cams have a clutch engagement with the toothed wheels on the handle-shaft and may be moved axially to a disengaged position.

The sections may be coated inside and outside with zinc, lead, copper, enamel, glass or the like, and the coating may be roughened by making impressions or indentations therein. The irregular surface thus formed may be made smooth before assembly by painting with a soft and hardening mass such as water glass, varnish, or a fine mortar. The uppermost section may be partly or completely filled with a light mass for receiving the connecting screws of insulator supports and the like. The lowermost section a may have an inner and outer concrete covering g having an annular groove h near the top for the attachment of the section a<1>. The rest of the groove is then filled with a material such as tar or asphalt. Specification 4828/84, [Class 36], is referred to. The Specification as open to inspection under Sect. 91 describes also a construction in which the sections are provided with longitudinal grooves for strengthening purposes. This subject-matter does not appear in the Specification as accepted.

Title: Range view finder for photographic cameras

Filed: 1959-10-21
Abstract: 934,762. Range and view finders. VOIGTLANDER A.G. Oct. 21, 1959 [Oct. 21, 1958], No. 35695/59. Classes 97 (1) and 98 (1). A range-finder consisting of a telescope forming an intermediate real image of a distant object is combined with a view-finder producing a virtual image of that object, the field of view being delimited by the edge of a mirror, which lies in the image plane of the range-finder objective and in the focal plane of the rangefinder eyepiece. Preferably, the view-finder is of the Albada type. As shown in Fig. 1 coincident images of an object are formed by light which passes to the eye of the observer through a semi-reflector 5 and by light which passes through a lens 10 and is directed through a lens 11 by mirrored surfaces 12, 14 and 13 and thence via a roof prism 15 to the semi-reflector 5 where it is directed into the eye. The lens 10 is slidably mounted and forms the real image of the object at the mirror 14 which acts to limit the field of view. Superposed on the coincident range-finder images, is a view-finder image, this view-finder being of Albada type having a concave mirror 6 which forms at infinity an image of a frame 7 deposited on the eye lens 4. Instead of the roof prism 15, a Dove prism may be inserted in the light path to the lens 10 which itself may be replaced by a fixed positive element and a movable negative element. In an alternative arrangement, the eye lens 4 is common to the view-finder and the range-finder, and in a further embodiment, the real image formed at the mirror 14 is in the focal plane of a concave mirror which directs the light into the semi-reflector 5. The rangeview-finder may be formed from a single glass block.
