GEORGE KINGSLY WALKER, OF MAQUON, ILLINOIS.

TOBACCO-CUTTER.

SPECIFICATION forming part of Letters Patent No. 524,622, dated August 14, 1894.

Application filed May 21, 1894:. Serial No. 511,926. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE KINGSLY WALKER, of Maquon, in the county of Knox and State of Illinois, have invented a new and Improved Tobacco-Cutter, of which the following is a full, clear, and exact description.

Theinvention relates to machines for cutting vegetable and other material, such for instance as tobacco, and its object is to provide a new and improved cutting machine which is comparatively simple and durable 1H construction, very efiective in operation, and arranged to thoroughly remove any gummy or other matter adhering to the cutting blade, so that the machine will always be 1n proper condition for performingits intended functions in a regular manner.

The invention consists in certain parts and details, and combinations of the same, as will be hereinafter fully described and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.

F1gure 1 is a face view of the improvement with parts broken out. Fig. 2 is a sectional plan view of the same, on the line 2-2 of Fig. 1. Fig. 3 is a transverse section of the same, on the line 3--3 of Fig. 1. Fig. 4: is an enlarged perspective view of part of one of the scrapers. Fig. 5is aface view of the out ter; and Fig. 6 is an enlarged transverse section of part of the improvement, on the line 5-5 of Fig. 1.

The improved cutting machine is provided with a suitably constructed base A, on which are supported the guide ways B, formed on opposite faces with grooves B in which are fitted to slide the sides of a cutter frame G, carrying the knife blade D, securely held in place on the said frame by a clamping bar E. On the upper end of the said cutter frame 0, is formed an upwardly-extending arm 0', carrying rack teeth 0 adapted to be engaged by a segmental gear wheel F, formed on the pivot or the fulcrum end of a hand lever F pivoted at F in the top connection B forthe guideways B. Now, when the operator imparts a swinging motion to the lever F, then the segmental gear wheel F, engaging the rack G, will cause a vertical sliding motion of the cutter frame 0, whereby the knife blade D is moved up and down to cutany material placed on the base A, between the guideways B. The ends of the knife blade D are fitted to slide in narrow slots 13 formed on the inner faces of the guideways B below the grooves B.

In order to prevent gummyand other matter from adhering to the knife blade D after a cut is made, I provide two scrapers G, Gr, engaging opposite faces of the said knife blade, as plainly illustrated in Fig. 3. Each scraper is made of sheet metal of a springy nature, and is formed with a longitudinallyextending part G formed at its ends with lugs G8 reaching to the guideways B, as plainly shown in Fig. 1, and from the longitudinal portion Gr extends downward and inward the inclined scraping part G resting of the knife blade D, as will be readily understood by reference to Figs. 3 and 6.

The lugs G engage with their upper portions bevels B formed in the faces of the guideways B, so that the said lugs G8 stand at an angle to the face of the guideways, and the projecting lower portion of each lug is engaged by a bolt H, so that when the nut of this bolt is screwed up, pressure is exerted on this projecting part of the lug G which causes the scraping part G to move with more or less force against the knife blade D. By this arrangement the lower edge of the scraper is held in proper contact with the knife blade to remove any gummy or other matter adhering to the blade after a cut is made, and at the time when the knife or cutter frame moves in an upward direction.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cutting machine, comprising guideways provided with beveled faces a frame carrying a knife blade and having a reciprocating motion in the said guideways, and scrapers engaging opposite faces of the said knife blade, and formed at their ends with lugs fitted on the said bevels of the guideways, bolts passing loosely through the said lugs and nuts screwing on the bolts to permit of with its lower edge on the front or rear face adjusting the scrapers to move their lower edges with more or less force into contact with the faces of the knife blade, substantially as shown and described.

2. A cutting machine, comprising guideways formed with bevels in their faces, a

frame fitted toslide in the said guideways.

and carrying a knife blade, means, substantially as described, for imparting a reciprocating motion to the said knife frame, scrapers adapted to engage with their lower ends opposite faces of the said knife blade, each scraper being formed witha longitudinal portion having perforated lugs at its ends, the saidlugs fitting partly zup onthe, said bevels, each scraper being also provided with an angular scraping part extending from the 10ngitudinal portion and adapted to engage the face of the knife blade, bolts passing loosely --throngh thesaid lugs, andmnts screwing on the bolts for engaging the said lugs, substantially as "shown and described.
