Patented Sept. 1, 1896.
' UNITED STATES PATENT rains.
CLARENCE \V. HOBBS AND WILLIAM TV. JOHNSTON, OF TVORGESTER, MASSACHUSETTS.
ADJUSTABLE CUTTER FOR SCORING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 566,758, dated September 1, 1896.
Application filed June 8, 1896. Serial No. 594,658. (No model.)
To aZZ whom, it may concern.-
Be it known that we, CLARENCE W. HOBBS and WILLIAM W. Jonns'ron, citizens of the United States, residing at Worcester, in the county of \Vorcester and State of Massachusetts, have invented a new and useful Improvement in Adjustable Cutters for Scoring- Machines, of which the following is a specification, accompanied by drawings, forming a part of the same, in which- Figure 1 represents a side view of an adj ustable cutter embodying our invention with the cutting disk in its highest position. Fig. 2 is a side view of our adjustable cutter with the cutting-disk in a lower position. Fig. 3 is a bottom view. Fig. 4c is an end view. Fig. 5 is a sectional view on line 5 5, Fig. 1. Fig. (i is a side view of the cuttersupporting frame and rotating cutting-disk with the sliding block which carries the cutting-disk shown in central vertical sectional view; and Fig. 7 is a central vertical sectional view on line '7 7, Fig. 4.
Similar letters refer to similar parts in the difierent figures.
Our invention relates to certain improvements in the construction of the adjustable cutters used in machines for scoring cardboard, and it has for its object to simplify the construction and to provide means for the vertical adjustment of the cutting-disk and for taking up lost motion in the movable parts of the cutter; and it consists in the construction and arrangement of parts as hereinafter described, and set forth in the annexed claims.
Referring to the accompanying drawings, A denotes a frame adapted to be adj ustably attached to the cutter-bar of a scoring-machine in the usual and well-known manner. Upon the lower edge of the frame A is a curved track A, formed in the arc of acircle and provided with a projecting rib Aiwhich enters a groove B in the correspondinglycurved edge B of the block B. The block B carries a spindle (3', upon which a rotating cutting-disk O is journaled.
Attached by a screw D to the front edge of the frame A is a plate D, projecting downward in front of the block B. The plate D is provided with a slit D dividing the end of the plate a little more than half its length in a plane at right angles to the plane of the frame A, thereby forming an elastic section D which is provided at its lower end with a lateral projecting foot D having the upper surface of the toe B curved, as at D, concentrically with the curved track A, and entering a circular notch C formed in the edge of the block B opposite the curved edge B and concentric therewith. The plate D holds a tightening-screw E, bearing against the heel of the foot D, by which the foot is crowded forward to hold the toe D firmly against the notched edge of the block B in close contact with the track A, allowing the block to slide freely between the concentrically-cuiwed surfaces of the track A and the toe D The plate D is also provided with a screw-threaded hole F, opposite the upper portion of the front edge of the block B, to receive an adjusting-screw F, provided with a check-nut F 'Attached to the inner end of the adj Listing-screw F is a cylindrical block F which is provided with an annular groove F The block is inserted within a recess G in the block B and is held therein by a pin G, held in the block and engaging the annular groove Ft The adjustingscrew F serves to adjust the position of the block B in order to raise or lower the cutting-disk O to regulate the depth of the cut in the cardboard, the cutting-disk Obeing shown in its highest or raised position in Fig. 1 and in a lower position in Fig. 2. The tighteningscrew E is prevented from working loose by means of a vertical slit E, extending from the vertical end of the plate D and on diametrically opposite sides of the screw E, causing the screw E to be pinched in the bifurcated end of the plate B.
We are aware that it is not new to construct the adjustable cutters of scoring-machines with a curved track, as at A, and with a on tter-carryin g block adapted to slide on said track and actuated by an adjusting-screw, as F, and we do not herein claim these features.
What we do claim as our invention, and desire to secure by Letters Patent, is
1. In an adjustable cutter for scoring-machines, the combination of aframe provided with a curved track, a block adapted to slide on said track, a cutting-disk carried by said block and a foot arranged to bear against the side of said block opposite said track, substantially as described.
2. In an adjustable cutter for scoring-machines, the combination of the frame A pro- Vided with a curved track A, a block B arranged to slide on said track, a foot bearing against the side of said block opposite said track and means for crowding said foot against said block, substantially as described. 7
3. In an adjustable cutter for scoring-machines, the combination of a frame provided with a 'circulartrack, 'a block sliding on said track, a cutting-disk carried by said bloc-k,
said block having a circular notch on its side opposite said track and concentric therewith,
