1 Claim.
The invention relates to an attachment for a metal cutting machine, and more especially to a chip-breaker device for use on a metal dressing machine or the like.
The primary object of the invention is the provision of a device of this character, wherein metal shavings cut from a piece of work by a dressing or turning tool operated by a machine will be broken up, thereby eliminating trouble which is caused by such shavings getting in the mechanism on the machine, and thereby retarding the working of the same or damage thereto.
Another object of the invention is the provision of a device of this character, wherein the adjustability thereof permits the proper setting of the same to the tool and the piece of work operated upon thereby, so that the strippings removed from such piece of work can be chipped or broken up automatically during the operation of a machine for the working of the tool.
A further object of the invention is the pro vision of a device of this character, wherein it is adaptable to various types of machines of the metal cutting types, so as to chip the shavings as removed from a piece of work by the tool, and in this way eliminating the clogging of the machine and interfering with its working, with resultant finishing of the work operated upon thereby.
A still further object of the invention is the provision of a device of this character, which is simple in construction, thoroughly reliable and efficient in operation, readily and easily adjusted to proper working position, strong, durable, positive in the working thereof, and inexpensive to manufacture and install.
With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which shows the preferred embodiment of the invention, and pointed out in the claim hereunto appended.
In the accompanying drawing:
Figure l is a front elevation of the device constructed in accordance with the invention and applied to a metal cutting machine.
Figure 2 is a side view thereof.
Figure 3 is a top plan view.
Figure l is a sectional view taken on the line 4-4 of Figure 1 looking in the direction of the arrows.
Figure 5 is a sectional view taken on the line 55 of Figure 3 looking in the direction of the arrows.
Figure 6 is an exploded perspective view of the device detached.
Similar reference characters indicate corresponding parts throughout the several views in the drawing.
Referring to the drawing in detail, A designates generally a portion of a tool stock or holder, of a metal cutting machine for turning metal work, B being the piece of work operated upon,
only a portion shown, by a cutting tool it, and
are illustrated merely to disclose the application of the chip breaker or shavings mutilating device constituting the present invention and hereinafter described.
The device constituting the present invention, comprises a substantially L-shaped hanger block or plate I I, having engaged in its longer arm several fasteners, such as screws 22, which detachably secure the block or plate l i in position on the stock or holder A, with the shorter arm or portion of this block or plate overhanging the tool II! at its cutting end l3 in working position to the piece of work B when operated upon by such tool. The shorter arm of the block or hanger plate II has adjustably attached thereto a bearing M', which attachment is had by a set screw l5 engaged in an elongated slot [6 provided in this shorter arm, so that the bearing can be adjusted laterally with respect to the tool 10.
Fitted to the bearing [4' to protrude from its forward face or outer side is a stud journal or horizontally-disposed shaft I! having rotatable thereon a peripherally grooved double cutting edged chipping roller 18, for the automatic kinking and chipping up shavings during the dressing or turning of the piece of work B by the tool In in the operation of the machine.
The innermost cutting edge is of this roller I8 is disposed close to the cutting end of the tool II] at the point of cutting action on the work B, so that the shavings removed from the latter will be acted upon by the roller I8 for the resultant kinking of the shavings 20 and the instant chipping orf at such kinks, of the same, during the cutting operation by the tool II] in the working of the machine. The position of the device is best seen in Figures 1, 2 and 3 of the drawing, and the action thereof on the shavings 29 removed from the piece of work B.
The roller I8 both kinks and breaks the shav ings 20 coming from the piece of work B during the turning and cutting thereof.
What is claimed is:
In a metal turning machine, a holder mounted on said machine, and a tool carried by said holder for turning a work piece, the improvement consisting of operatively connecting a device to said holder for kinking and breaking the shavings removed from said work piece, said device comprising a plate arranged in superposed relation with respect tosaid holder and releasably secured to the latter, a portion of said plate projecting beyond said holder and positioned above said tool. a bearing dependingly supported by said projecting portion and adjustably mounted for lateral movement With respect to said plate, a horizontally-disposed shaft projecting from the forward face of said bearing and secured to the latter, and a grooved roller rotatably mounted on the projecting end of said shaft.
