380,735. Slicing bread. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co.; 511, 5th Avenue, New York, U.S.A.) March 23, 1932, No. 8622. [Class 5 (i).] A transfer mechanism, applicable to the delivery of sliced loaves from a slicing-machine to a wrapping-machine, comprises gripping devices and an associated feeler operable to grip and release the article at predetermined positions. The'loaves L, Fig. 1, after passing slicing apparatus 35, pass on to a table 36 between guides 37. A carriage 29, coupled to a slide 28, and carrying the grippers, is reciprocated on slide bars 30, 31 by links 16 .. 19 and rod 27 from a crank 15. As soon as the carriage has been moved to the right, Fig. 1, and a feeler 38, pivoted thereon at 40, contacts with a loaf on the table 36, the feeler is lifted and turns an arm 41 to swing a support 43 and allow an arm 34 to be pulled downwards by a spring. This disconnects the carriage 29 from the slide 28 ; the former remains stationary at the point at which the feeler encountered the loaf, and the latter completes its stroke. During the latter movement, a trip 48, Fig. 2, is moved so as to release an arm 49 to move in a clockwise direction under the action of a spring 50. Adjustable links 54, 60 transmit the motion to the grippers 56, 61, which are caused to close upon the loaf. The slide 28 executes its movement to the left, Fig. 1, carrying with it the carriage 29. Upon arrival at the loaf discharging position, the grippers are caused by fixed cams to separate and disengage the loaf and the parts are similarly reset for the next operation. The loaf descends on to a. conveyer 69, along which it is carried by projections 77 on chains 74, and is carried into the wrapping machine by a pusher 80 on chains on sprockets 82, 83.
