CiGAR-MAKiNG MACHINE.

Application filed. April 15, 1912.

To all whom 2'25 may concern:

Be it known that T, CHRISTIAN F. BREMER, a citizen of the United States, residmg at Tampa, in the county of Hillsboro, State.

of Florida, have invented certain new and useful Improvements in Cigar-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in cigar making machines.

The principal object of the invention is to provide a machine which is designed for the manufacture of better grade cigars where imitations of hand-work is desired.

Another object of the invention is to provide a cigar making machine in which a novel means is employed for bunching the tobacco previous to applying the wrapper.

A further object of the invention is to provide a machine for the purpose described which can be operated by one bunch breaker on one side and one cigar roller on the other side.

A still further object of the invention is to provide a machine of the character described in which the rolls are automatically opened and closed thereby avoiding the necessity of the operators manually performing that work.

A still further object of the invention is to provide a machine of the character de scribed which is simple in construction, it being composed of a minimum number of parts, is ositive in operation and is cheap to manufacture.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction with in the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is an enlarged longitudinal sectional view through the bunching mechanism of a cigar making machine constructed in accordance with my Specification of Letters Patent;

Patented Dec. 9,1913.-

Serial No. 690,884.

invention, Fig. 2V is a side elevational View of the complete machine, Fig. 3 is a vertical longitudinal sectional view through the machine showing the bunching mechanism in elevation, Fig. 4: is a transverse sectional view taken through the power shaft, Fig. 5 is a perspective view of a mold section, showing the tobacco receiving recess, and Fig. 6 is a similar view of the mold section, but showing the opposite face thereof.

Like reference numerals designate corresponding parts in all the figures of the drawings.

Referring to the drawings, A designates a bench which includes a top 5 that is suit ably supported by legs 6 and braces 7. A transverse partition 8 centrally extends across the top 5, and side-boards 99 are also secured to the top end of the partition.

Centrally formed in the top 5 is a longitudinally disposed rectangular opening 10, said opening extending on opposite sides of the partition 8, and located in this opening is my improved bunching mechanism which is designated as a whole by the reference letter B. Front and rear shafts 11 and 12 respectively are disposed transversely across the opening 10 on opposite sides of the partition 8, these shafts being rectangular in cross section and having trunnions 11 and 12 respectively extending from the ends thereof and suitably journaled in bearings 13 mounted on the top 5 on opposite sides of the opening 10. This mechanism includes an endless conveyer, which is designated as a whole by the reference numeral 1 1. This conveyer is formed from a series of abutting mold sections 15, each section being rectangular in shape and having a cross sectional area equal to that of either of the shafts 11 or 12. Formed in one of the abutting faces of each section 15 is a longitudinally disposed recess 16 which corresponds in size to the shape of the cigar to be formed. This recess opens at its ends, as indicated by the reference numerals 16 and 16*, the former opening being larger than the latter. Projecting from the opposing face of the next adjacent section 16 is a complementary projection 17 which is adapted when the sections are disposed in abutting relation to partially extend into the recess 16, and thereby compresses the tobacco. These sections are fixedly connected to an endless belt 18 which is trained over the shaft 11. Also formed in one face of each section 15 and between the recess 16 and the inner edge of said section is a longitudinal groove 19 which receives a rib 20 which projects from the inner edge of the opposing face of the next adjacent section, said projection 20 being disposed below the projection 17.

Fixed upon each trunnion 11 of the front shaft 11 is a ratchet 21 and also fulcrumed upon each trunnion 11 is a lever 22 which carries a spring pawl 23 for engagement with a respective ratchet. Each lever 22 is slightly bent forwardly, and connected to the upper forward end thereof is one end of a connecting cord 24, said cord being connected at their lower ends by a treadle 25 which is hingedly connected to a transverse frame member 26. A spring 27 is connected at one end to the treadle 25 and at its other end to the top 5 of the bench and serves to normally hold the treadle 25 in its upright or normal position. It will be seen that the shafts are rotated through ninety degrees at each downward movement of the treadle. In order to prevent the sections from buckling when in travel, there is provided on either side of the conveyer 14 a pair of brackets 2828, and these brackets support a trans erse roller 29 which is disposed above and engageable with the sections 15 as they pass thereunder.

In operation, the operator at the front end of the machine places a sufficient amount of tobacco in the section 15 which is arranged at the front of the mechanism above described. The treadle 25 is then depressed against the tension of the spring 27, and as a result, the levers 22 are rocked upon their fulcrum and through the medium of the pawls 23 engaging with the ratchets 21, the power shaft 11 and consequently the driven shaft 12 is rotated for one step, this movement swinging the section 15, in which has been previously placed the tobacco, upwardly upon the shaft 11, and at the same time brings the next section 15 into proper working position. As the sections are thus caused to intermittently travel rearwardly, the tobacco is compressed within the recesses 16 by means of the projections 17. As the section containing the compressed tobacco reaches the rear end of the mechanism, the sections 15 will automatically swing around the shaft 12 as will be readily understood, and when a section 15 is disposed against the rear face of the shaft 12, the recess 16 of the section 15 on said shaft 12 is thereby automatically opened. By this means it will be observed that the mold is automatically opened so as to permit the operator to readily remove the compressed tobacco. Simultaneously with this movement the sections at the front end of the machine are automatically swung into position for receiving the tobacco within the recesses 16*.

lVhat is claimed is:

1. In a cigar making machine, the combination of a pair of spaced rectangular shafts, a conveyer trained around said shafts including a series of transversely arranged abutting mold sections, and a guide roller disposed transversely above the conveyer for engagement by the sections said roller being wholly above the plane of movement of the sections.
