To permit high speed of operation, the cigarettes are urged downwardly in the chutes by air jets so that following the ejection of a batch of cigarettes from the chutes, the next batch to be ejected will move quickly into ejection position. To prevent tilting of the cigarettes in the chutes, the ends of the cigarettes next to drop into ejection position are engaged by a stop member until the ejecting member is withdrawn from beneath the cigarettes, whereupon the stop member is withdrawn and the cigarettes dropped to ejection position while remaining horizontal. The supply of compressed air to the nozzles is preferably regulated so as to take place at about the instant the cigarettes are to drop to ejection position.，下面是Feeding device for cigarettes for cigarette packing machines专利的具体信息内容。

权利要求

1. An apparatus for feeding batches of cigarettes and comprising: a hopper having a plurality of chutes leading downwardly therefrom and terminating in side by side relation, each chute being adapted to receive a stack of cigarettes by gravity from the hopper with the received cigarettes in horizontal position, a base plate at the bottom of said chutes to support the cigarettes therein, said chutes being open at the ends of the cigarettes therein to permit endwise ejection of the cigarettEs from the chutes, a member reciprocable in the direction of the length of the cigarettes and having pin means thereon to engage the ends of the cigarettes to be ejected so as to push the cigarettes from the chutes, the cigarettes in the chutes above the ones ejected therefrom dropping to ejection position upon retraction of said reciprocable member following an ejection stroke thereof, and means localized at the lower exit end of said chutes and for urging said cigarettes downwardly in said chutes to speed up the said dropping thereof to ejection position, said means including nozzle means operable for inclined directing, opposite to each other briefly during retraction of said reciprocable member, only two jets of compressed air transversely against longitudinal axis of cigarettes in said chutes in the generally downward direction.

2. An apparatus according to claim 1, in which said nozzle means are arranged inclined to the drop direction along opposite ends of said chutes near the ends of cigarettes in said chutes and are adapted to be supplied with compressed air.

3. An apparatus according to claim 2, in which said nozzle means are located angularly downwardly and inwardly at a level such as to cause the jets therefrom to impinge against the cigarettes which will be uppermost in the chutes when the cigarettes are horizontally in ejection position.

4. An apparatus according to claim 1, which includes a stop member on the side of said chutes toward which the cigarettes are ejected adapted to engage beneath the adjacent ends of the lowermost non-ejected horizontal cigarettes in said chutes respectively, and means for withdrawing said stop member from holding rail relationship beneath the adjacent ends of said cigarettes to permit the cigarettes to drop to ejection position.

5. An apparatus according to claim 4, in which the said stop member is adapted for being pivotally withdrawn from holding rail relationship beneath the adjacent ends of said cigarettes at about the same time as said pin means.
