Applicationfiled June 19, 1907., Serial No. 379,811.
To all whom it may concern:
Be it known that 1, CHARLES a citizen of the United States, residing at Ronceverte, in the county of Greenbrier, State of West Virginia, have invented certain new and useful Improvements in Machines for Cutting Bu11gs;.and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.
This invention relates to machines for cutting barrel bungs and has for its object to provide a machine of this class in which the knives are 'normally'held out of operative position and to provide manually operable means whereby knives may be simultaneously moved into operative position at the will of the operator.
In attaining this object, I provideat the upper end of each of the knives a roller and slidably mount upon the shaft upon which the cutter head is carried a spider which is normally held so that its arms will be out of contact with the rollers but which has engaged with it a lever which may be rocked to shift the spider into such engagement and thereby feed the knives downwardly.
In the accompanying drawings, Figure 1 is a side elevation of the machine, and, Fig. 2 is a top plan view of the machine, the shaft being shown in section and one of the spider arms being broken away at its ends to show the relation of the arms to the rollers at the upper ends of the knives.
As shown in the drawings themachine includes a driven shaft 5, which while it may be mounted in any suitable frame or support in any desired manner, is here shown as ournaled in bearings 6 upon a pair of beams 7 there being a pulley 8 upon the shaft intermediate the beams. The lower portion of the shaft 5 is squared as indicated. by the numeral 9. and fixed upon the shaft at its extreme lower end is the cutter head 10 of the machine, this cutter head being substantially cylindrical in form. Formed obliquely through the cutter head and opening through its upper and under faces are curved slots 11, the slots being curved concentrically with respect to the head itself. The knives 12 of the machine are slidably received through these slots and are curved transversely to conform to the curvature of theslots, it
being understood that by reason of the fact that the slots are formed obliquely through W. KlINCAID,
V the head, the knives will extend obliquely downwardly and inwardly toward each other.
il Vhile T have shown four knives in the "drawings it will be understood that any desired number may be employed as maybe found expedient without departing from the spirit of the invention.
The lower end of each knife 12 is bent back "upon itself as at 13 and one edge of the curved lower end portion thereof is' sharpened to form the cutting edge 14 it be ng understood that these edges of the knives are their working edges and that the cutterhead-is to be rotated in the direction in which these edges are presented.
7 Mounted for vertical sliding movement upon the squared portion 9 of the shaft 5 is a spider 15 including radial arms 16 which are equal in number to the knives 12 and which have their under faces flat, it being understood that each arm of the spider extends directly above a single knife. A spring 17 which is engaged upon the squared portion of the shaft 5 bears at its lower end against the upper face of the cutter head 10 and at its upper end against the under side of the spider 15 and serves to hold the spider normally in raised position and out of engagement of its'arms with the upper ends of the knives. The knives are also normally held in raised position by means of leaf springs 18 which include attaching portions by which they are secured to the upper face of the cutter head, one directly inwardly of each knife, and have their upper ends connected with the knives whereby the tension exerted by the springs, they being bowed and having a tendency to straighten out, will act to raise the knives.
Journaled in bifucations 19 formed in the upper ends of the knives 12 are rollers 20 and it is againstthese rollers that the arms 16 bear when the spider is lowered. In order that the spider may be lowered as stated above, a lever 21 is pivoted as at 22 upon a hanger 23 and is provided adjacent its middle with a collar portion 24 which fits loosely over a collar 25 formed upon the spider 15 at the center thereof.
From the foregoing description of my invention it will be apparent that by swinging against the tension of the spring 17 and it will further be understood that further movement of the lever will result in the knives being fed downwardly in the direction of a table or support 26 for the board from which the bangs are being cut, and inwardly toward each other in oblique planes. It is apparent that upon releasing the lever 21 it will be swung upwardly to its normal position by the action of the spring 17 and that the knives, after the arms 16 have moved out of engagement therewith,
' will be raised through the instrumenta'lity of the springs 18. This upward movement of the lever and the spider is limited by a cross pin 27 which is engaged through the squared portion 9 of the shaft 5. It will also be understood that by reason of the fact that the lower end portions of the knives are bent back upon themselves, the bung will be formed by cutting an annular groove in the board and that room is provided, by reason of this construction, for the passage of chips or shavings cut from the board.
What is claimed, is-
In a machine for making bangs, a rotatable shaft, a spider slidable lengthwise thereon and rotatable therewith, a cutter head mounted on the shaft below the spider and having longitudinal slots, knives slidably mounted in said slots and having their cut ting portions projecting from the bottom of the cutter head and their shanks from the top thereof in the path of the spider arms, means for advancing the spider against the projecting shanks of the knives to feed the same into the work, and flat springs connected at one end to the top of the cutter head and at the other end. to the shanks 0t the knives for retracting the same when the CI-rAs.
