Opinion

Hatfield, Judge,

delivered the opinion of the court:

This is an appeal from the decision of the Board of Appeals of the United States Patent Office affirming the decision of the Primary Examiner rejecting claims 8, 9, 11, 12, 13, 17, and 23 to 31, inclusive, in appellant’s application for a patent for an alleged invention re[766]*766lating to an automatic scrap (short filler) tobacco feed for cigar machines.

Seventeen claims were allowed by the Primary Examiner,.

The appealed claims may be divided into three groups as follows: Group 1, claims 23 to 31, inclusive, of which claim 25 is representative; group 2, claims 8, 11, 12, 13, and 17, of which claim 8 is representative ; and group 3, claim 9.

Claims 25, 8, and 9 read:

25. In a machine for forming- cigar bunches, the combination with side and bottom belts forming a tobacco receiving channel, of a hopper for holding a supply of tobacco, means cooperating with said hopper and channel for feeding tobacco from said hopper into* said channel to form a stream of tobacco therein, means coacting with said belts to forward the stream of tobacco, a bunch rolling apron, a device at the forward portion of said channel for separating a length from said stream substantially equal to the length of the bunch to be formed, and transfer mechanism including a reciprocable element movable downwardly onto the upper surface of said bunch length and displacing said length downwardly with respect to said channel, for transferring the unshaped bunch length having substantially the cross-section of said channel to said apron, and means for holding back from the stream of tobacco fed from said hoixper all tobacco above a predetermined height in said channel to provide a stream with a cross-section sufficient when rolled to form a bunch of the desired diameter.
8. In a cigar bunch machine, the combination with a vertical intermittently rotating hopper for holding a supply of filler tobacco, of means for feeding tobacco from said hopper in a continuous approximately bunch width stream, a cutter for separating approximately a bunch length from the forward portion of said stream, means for displacing the bunch lengthwise relative to the length of said stream, out of line with said stream, and a rolling apron for rolling said separated and displaced bunch length to form a cigar bunch.
9. In a cigar bunch machine, the combination with a vertical intermittently rotating hopper for holding a supply of filler tobacco, of means for feeding tobacco from said hopper in a continuous approximately bunch width stream, a cutter for separating approximately a bunch length from the forward portion of said stream, means for displacing the bunch length sidewise relative to the length of said stream, out of line with said stream, and a rolling apron for rolling said separated and displaced bunch length to from a cigar bunch, said feeding means including devices acting on the pieces of filler tobacco to arrange the tobacco in said stream with elongated pieces extending in a generally lengthwise direction relative to the length of said stream whereby the pieces will be arranged lengthwise in the completed bunch.

As will be observed from the quoted claims, appellant’s device is provided with, a tobacco hopper rotatable about a vertical axis, and a “receiving” or “feed” channel. In order to prevent the tobacco from sticking to the sidewalls, the hopper is provided with a number [767]*767of agitators which rotate intermittently in the same direction as the hopper but at a different rate of speed. The bottom of the hopper ■consists of a stationary cone mounted on a bottom plate. The plate is provided with a slot which overlies the feed channel. One side of the stationary cone is flattened, as stated in appellant’s application, “along a vertical plane coinciding with one side of the slot” in the plate forming the bottom of the hopper to permit the tobacco in the hopper to pass into the slot. The feed channel is formed by two side guide belts and a bottom guide belt. The belts travel in an opposite direction from, and in synchronism with, the hopper, “whereby the serrated lower edges of the hopper serve to level the •stream of tobacco in the channel and prevent chocking of the same.” The serrated edges also serve to turn the pieces of tobacco so that they will lie in a longitudinal direction lengthwise of the channel. The hopper, the agitators, and the belts forming the feed channel ■are driven in synchronism. A bunch length of the tobacco in the forward end of the channel is compressed and, by means which need not be here described, is transferred to a bunch rolling apron where it is formed into a cigar bunch.

The patent to Bohls relates to a machine for feeding tobacco to a cigarette forming mechanism, and discloses a vertically rotating hopper from which, by means of rotary agitators in the hopper, the filler tobacco is fed in a continuous stream through an outlet in the bottom of the hopper onto a belt provided with teeth moving beneath the hopper. The belt carries the tobacco to “picker rollers.” As the tobacco is being conveyed by the belt to the first “picker roller” it passes beneath a guard plate which forces it down between the teeth of the belt. The patentee states that, as the first “picker roller” moves at a higher rate of speed than the belt, “the teeth of the latter [the belt] somewhat retard the tobacco and 'a further combing or disentangling takes place.”

The patent to Rundell relates to a long filler type of cigar-making machine, and discloses a machine in which the tobacco is placed manually in a “cross feed” channel formed by two side belts and a bottom belt. No hopper is disclosed. The tobacco in the channel moves beneath a cutter which separates a bunch length of the tobacco which is delivered to a bunch rolling mechanism. The patentee states that- in the type of machine there involved “individual charges of filler are severed from a continuous stream, transferred to a compressing device, there compressed, then transferred to a rolling device where a wrapper is applied to it.”

The patent to Bronander relates to a device for feeding scrap tobacco to cigar-making machines, and discloses a machine in which the tobacco is fed from a hopper onto a belt. The patentee states that the tobacco must be leveled on the belt, and that “the long scraps [768]*768must be turned so that they will lie along the conveyor if they are not already lying in that direction.” In order that that purpose may be accomplished, the patentee’s device is provided with what he terms “S-shaped rakers,” which, it is stated, ‘‘gradually level the stream of tobacco [on the belt], straighten Jong scraps which need it, and throw back all tobacco in excess of the 'ultimate quantity required for final delivery.”

The patent to Carlson relates to a rotary tobacco feed for cigar machines, and discloses a hopper having a “stationary central portion [with agitators therein] and a pair of outwardly dished revolving ends or sidewalls.” The agitators serve to “loosen tobacco and to arrange elongated tobacco scraps with their lengths extending in one direction.” The stationary central portion is supported on a base plate by means of brackets.
