Strewing apparatus, especially for baking installations

Claim 2

A strewing apparatus, especially for baking installations, comprising container means having an open lower end and narrowing in cross-section towards said open end, said container means incorporating a front wall and a rear wall, a base plate for closing the major portion of said lower open end of said container means, oscillating support elements for mounting said base plate at said rear wall of said container means for carrying out an oscillatory movement up and down substantially in a direction of downward feed of the strewable material through the open end of said container means, said base plate including a marginal edge portion spaced in confronting relationship from and cooperating with said front wall of said container means to provide therebetween a throughpassage slit for the material to be strewn, oscillating drive means arranged behind said rear wall of said container means for placing said base plate into oscillatory motion such that said base plate together with said marginal edge portion thereof which forms said throughpassage slit with said front wall is primarily moved up and down, said throughpassage slit extending substantially transversely with respect to said downward feed of said strewable material from said container means through said open end thereof, the upward movement of said base plate at least at the beginning of its motion occurring in substantially jerky-like fashion, and additional means for independently adjusting the basic width of said throughpassage slit.

Claim 3

A strewing apparatus as defined in claim 1, wherein said oscillating drive means incorporates cam disc means and electric motor drive means, feeler means fixedly connected with said base plate, said cam disc means acting upon said feeler means.

Claim 4

A strewing apparatus as defined in claim 2, wherein said electric motor drive means comprises a motor transmission block means.

Claim 5

A strewing apparatus as defined in claim 2, wherein said cam disc means possesses at least one gradually ascending cam profile section and a given number of steeply descending cam profile section means arranged in such a fashion that the oscillatory movement imparted to said base plate additionally favorably affects the migration of the strewable material located lowermost in said container means towards said throughpassage slit.

Claim 6

A strewing apparatus as defined in claim 1, wherein said container means further includes a pair of side walls fixedly connected with said rear wall, means for pivotably mounting the upper end of said front wall of said container means with said side walls, and wherein said additional means act upon said front wall of said container in order to adjust said basic width of said throughpassage slit.

Claim 7

A strewing apparatus, especially for baking installations, comprising container means having an open lower end and narrowing in cross-section towards said open end, said container means incorporating a front wall and a rear wall, a base plate for closing the major portion of said lower open end of said container means, oscillating support elements for mounting said base plate at said rear wall of said container means, said base plate including a marginal edge portion cooperating with said front wall of said container means to provide a throughpassage slit for the material to be strewn, oscillating drive means arranged behind said rear wall of said container means for placing said base plate into oscillatory motion such that said base plate together with said marginal edge portion thereof which forms said throughpassage slit with said frontwall is primarily moved up and down, the upward movement of said base plate at least at the beginning of its motion occurring in substantially jerky-like fashion, said oscillatIng drive means incorporating cam disc means and electric motor drive means, feeler means fixedly connected with said base plate, said cam disc means acting upon said feeler means, additional means for independently adjusting the basic width of said throughpassage slit, means for displaceably mounting said electric motor drive means together with said cam disc means at said container means in such a fashion that by changing the position of said electric motor drive means and said cam disc means it is possible to vary the amplitude of said base plate.

Claim 8

A strewing apparatus, especially for baking installations, comprising container means having an open lower end and narrowing in cross-section towards said open end, said container means incorporating a front wall and a rear wall, a base plate for closing the major portion of said lower open end of said container means, oscillating support elements for mounting said base plate at said rear wall of said container means, said base plate including a marginal edge portion cooperating with said front wall of said container means to provide a throughpassage slit for the material to be strewn, oscillating drive means arranged behind said rear wall of said container means for placing said base plate into oscillatory motion such that said base plate together with said marginal edge portion thereof which forms said throughpassage slit with said frontwall is primarily moved up and down, the upward movement of said base plate at least at the beginning of its motion occurring in substantially jerky-like fashion, said oscillatIng drive means incorporating cam disc means and electric motor drive means, feeler means fixedly connected with said base plate, said cam disc means acting upon said feeler means, additional means for independently adjusting the basic width of said throughpassage slit, means for displaceably mounting said electric motor drive means together with said cam disc means at said container means in such a fashion that by changing the position of said electric motor drive means and said cam disc means it is possible to vary the amplitude of said base plate.

Claim 9

A strewing apparatus as defined in claim 1, wherein said oscillating support elements are positioned to mount said baseplate at said rear wall of said container means for oscillation about a pivot point which is disposed above the plane containing said base plate, said throughpassage slit for the material to be strewn remaining of substantially constant size throughout said oscillatory motion of said base plate.
