Abstract: 1492. Aldred, R. J. r., and Aldred, A. E. Jan. 21. Cylinder machines; feeding and measuring.- Dough is fed by feed-rolls 5 from a hopper 2 into a feed - chamber 3, Fig. 4, in which works a plunger 7 adapted to cut off a supply of dough and feed it into a plunger chamber 8, one side of which is constituted by the plunger 7, a plunger 9, Fig. 3, being then operated to force the dough into one compartment of a rotary measuring-head 11, at the same time discharging the opposite chamber 12. The plunger 7 is operated by a cam 24, Fig. 4, on the main shaft 23, mounted on which is a second cam 28, which engages with a pin 29, Fig. 3, carried by a swinging link 31, coupled to the plunger 9 through the medium of a link 30 and levers 33, 39. An arm 41 of the lever 33 abuts against the rear of the lever 39, and is normally kept in engagement therewith by means of a spring 44 abutting against the lever 39 and against a collar 43, which is mounted on a rod 42 passing through the lever 39 and retained by the arm 41. The spring 44 regulates the pressure on the dough, and the stroke of the plunger 9 is varied by means of gearing 36, 37, which positions the end of the link 30 along the lever 33. Intermittent gearing for operating the drum 11 comprises a wheel 22 on the shaft 23 carrying a pin 45, yieldingly secured to which is a chain 46 passing around a sleeve 47, Fig. 13, loosely mounted on the drum spindle 14 and carrying a spring pawl 49, Fig. 14, which is adapted to engage with teeth 50 formed on a collar secured to the spindle 14 ; after having been moved forwards through half a revolution by the chain 46 and the wheel 22, the sleeve 47 is returned by a spring 48. The feed-rolls 5, Figs. 3, 4, are connected together by gearing 6, and to the spindle 14 by bevel-gearing, so as to be operated when the drum 11 is rotated. The drum 11 is provided with two diametral mould chambers fitted with loose unconnected plungers 73, Fig. 6, which are adjustably spaced apart by means of oppositely-threaded rods 59, Fig. 5, held slidably and non-rotatively in a yoke 60, and operated to vary the capacity of the moulds by means of a sleeve nut 58 actuated by bevel-gearing 62, 63, which is controlled by a band operated spindle 64 passing through the drum spindle 14. A screwed sleeve 66, held against rotation by means of a screw 67 projecting into a slot therein, is moved longitudinally when the spindle 64 is operated, and operates a rod 68, Fig. 10, carrying a pointer which indicates the capacity of the moulds on a scale 71. Spring catches 51, Fig. 6, moving in slots 54, retain the plungers 73 within the drum 11. To prevent injury to the operator through getting his hands in the chambers of the drum 11 when this is rotating, the starting-lever 78, Fig. 4, carries a guard 77 which covers the drum when the machine is set into operation. A brake 73, Fig. 3, retards the movement of the drum 11 and also forms an air cushion to prevent " hammering due to the dropping of the plungers when the machine is running empty. The drum may be operated independently by means of a band-wheel 14, Fig. 4.
