TOBACCO-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 261,763, dated July 25, 1882.

Application filed September 20, 1880. (No model.) Patented in Germany June 29, 1880, No. 11,762, and in England October 15,

To all whom tt may concern Be it known that we, GUsT. ALB. REINIGER and CHRISTIAN PETRI, of Stuttgart, Wiirtemberg, Germany, have invented certain new and useful Improvements in Engines for Outting Tobacco, of which the following is a specification.

This invention relates to a tobacco cutting machine secured to me by Letters Patent in Germany, numbered 11,762, and dated June 29,1880; and it consists in the features of construction and combination, hereinafter fully described and claimed, and illustrated in the annexed drawings, in which Figure I is a side viewof themachine. Fig.

11 is a top or plan view; Fig. III, a longitudinal section; Fig. IV, a cross-section on lineA B, Fig. I; Fig. V, a front endview, and Fig. VI a rear end view. I

Referring to-the drawings by'the referencenumbers, 2 indicates a stationary iron or other metal trough or box, which is made semicircular in cross-section and mounted upon two frames or standards, 1 1, so as to incline downwardly toward the cutting end of the machine, as shown by dotted lines, Fig. I. This trough is provided withazinclining, audit is strengthened by suitable ribs cast on its ends. The sliding carriage, which is arranged to travel 0 along this stationary trough, consists essentially of a frame or body, 4, which is preferably made of castiron and adapted to surround the outer side of the stationary trough 2 without touching the same. Thecarriage-body has 5 formed along each of its two upper side edges a horizontal flange, and to these flanges'are bolted the pieces 5, which have in their inner sides the V-shaped grooves, receiving similarly-shaped flanges 3 upon the upper edges 40 of the trough 2. These grooved pieces, which constitute a portion of the carriage, slide-upon the flanges of the trough, whereby the carriage will be properly guided in its movement. A further portion of the carriage consists in a 5 strongsemi-cylindrical sheet-metal trough, 6,

that is secured by suitable connections at its upper 'edgesto the grooved pieces 5, and fitted closely within the trough 2, and is arranged to slide, with the carriage, along the stationary trough.

Upon one side of the carriage-body are cast the two lateral tongues or projections 7 and 8, (see Fig. IV,) which constitute guides for the two vertical arms of a vertically-movable half-nut, 9, and alongside of the stationary trough is arranged the leading screw or spindle 12, supported in suitable bearings at the end of the said trough, the said half-nut being adapted to be raised and broughtinto engagement with the leading-screw, or to belowered and disengaged therefrom. The half -nut is raised, so as to engage the leading-screw by means of a lever, 11,0ne end of which is adapted to bear against the lower vertical arm of the half-nut, while the remaining end of the lever is provided with an adjustable Weight, 10. This lever is capable of both horizontal and vertical movements about a center-pin and swivel, (see Figs. III and IV,) which connect thesame with the movable carriage.

As long as the lever 11 exerts an upward pressure against the half-nut 9 the latter will be forced into engagement with the leadingscrew; but as the carriage travels, carrying the lever along with it, the lever will strike a stop, as, on the main frame, (see Figs. I and IV,) whereby the lever will be swung round upon its swivel-connection with'the carriage and moved from under the nut, thereby allowing the nut to drop and disengage from the leading-screw. The carriage, being thus entirely freed from connection with the leading-screw, can be freely moved backward or forward on the flanged guides 3 of the stationary trough.

It will also be observed that while the lever 8 5 is'under the half-nut it is held in contact with the same by the weight 10, and that it can at any time be disengaged from the lower arm of said nut by raising its weighted end.

The leading-screw 12 has a ratchet-wheel, a 13, rigid on one of its ends, and it is driven by means of a pawl, 15, engaging the ratchetwheel. This pawl is hung upon the pivot connecting the connecting-rod 16 with the lever 14, which is loosely mounted at one end 5 upon the end of the leading-screw.

The connecting-rod is reciprocated by means of a suitable adjustable crank-throw, 18, and 19, operated by the counter or knife'shaft 17.

The counter-shaft 17 is supported on two hearings in the standards 26, that are cast or secured on the main stationary trough, and it is driven by means of the three-to-one gearing 20 and 22, the former, 20, being upon the knife or counter shaft, and the latter, 22, upon a lower hand-crank shaft, 21, which can be conveniently operated by the hand-crank 23.

On the end of the knife-shaft farthest from the driving-gear is secured the cutting-knife arm 24, provided with a movable knife, 25.

, Upon the standard 26, that is at the front or cutting end of the machine and nearest to the knife, is fitted a vertical slide, 27, which serves to support the metal cover 28, arranged to lie upon the tobacco, and which, by reason of said 7 support, will not be moved forward with the tobacco as the latter is fed along to. the knife.

The cover 28 is composed of curved sheetiron or other suitable metal, and is arranged within the trough, with its convex side downward and toward the tobacco. To this metal cover is fixed an iron or other metal rod, 29,

that has upon its rear end a hinged piece, 30, formed with teeth along a portion of its length.

This hinged toothed piece is arranged to engage a lug or projection on the main stationary trough, and it can be set so as to suit the height of the tobacco, the cover just described being pressed down upon the tobacco, as presently described, and supported by means of a lever, 31, connected with one end of the rod 29. Beneath this cover 28 lies the tobacco holder or fork 32, which rests in a recess or hook, 33, fixed to the carriage.

The front part of the tobaccoholder is secured to a leather plate, 34, that is arranged above the said holder, and in the under side of the tobacco-holder is secured a suitable number of spikes or teeth.

An iron or other metal rod, 35, bent into elbow form at its ends, has its upper end resting upon the cover-rod 29, and when depressed serves to press the tobacco together and hold the teeth of the fork in the same. The lower 7 end of this rod 35v is securedbeneath the maco up fine. At the same time the knife-shaft,

through the mechanism already described, operates the ratchet-feed so as to rotate the leading-screw intermittently, and thereby feed forward the carriage and carriage-trough containing the tobacco toward the knife, the tobacco being laid in the carriage-trough when the carriage is at the highest point in its travel on the stationary trough. The tobacco will be laid longitudinally in the carriage-trough and the toothed holder forced into the tobacco and fixed at one end in-the notch of the hook 33. The half-nut being pressed up against the leading-screw, so as to engage the same, the carriage will be feed forward toward the knife, carrying the tobacco with it, the tobacco being held more securely down by depressing the rod 35. When, however, the lever 1 l strikes the projection m it will be swung round and the nut allowed to drop and disengage from the leading-screw, whereby the forward feed of the carriage will be stopped. After this the carriage can be moved back and refilled with tobacco.

The cutting apparatus might be modified by employing a guillotine-knife operated by a crank, and the shape of the trough could also be modified by making it rectangular in crosssection, the carriage being correspondingly modified in shape; also, the half-nut could be secured in place by a trigger instead of by a weighted lever.

What we claim, and desire to secure by Letters Patent, is-

1. The combination, in atobacco-cutting machine, of the knife, with the carriage provided with a trough for holding the tobacco, and supported upon guides, the screw arranged to move the carriage forward, and also arranged to be driven by the driving-shaft that actuates the cutting devices, and mechanism for automatically releasing the carriage from connection with the feed-screw, whereby after the completion of its forward movement it can be pushed back by hand, substantially as described.

2. In a tobacco-machine, the carriage arranged to convey the tobacco to the cutting knife, in combination with the vertically-movable half-nut 9, the rotary leading-screw, and mechanism arranged to cause the engagement of the nut with the screw, and also to automatically effect the disen ga gement of said parts, substantially as described.
