The object of myinvention is to provide a new and improved chip-breaker for woodworking-machines, whereby the pressure may be selectively directed to difierent points transversely of the cutter-head; and it consists in providing a pressure device for the chip-breaker arranged to be adjusted to different positions longitudinally of the cutter-V head, and, further, in the parts and in the construction, arrangement, and combinations of parts hereinafter more fully described and claimed.

In the drawings, Figure 1 is an end elevation of myimproved device showninconnection with adjacent parts of a woodworkingmachine. Fig. 2 is a plan view of the same. Fig. 3 is an end elevation of my improved device partly in section for better illustration of parts. Fig. 4 is a side elevation of my improved device shown in raised position, and Fig. 5 is a detail in end elevation of the swinging arm for the same.

A represents the frame of the machine, in

which a cutter-head. B may be suitably journaled, and 0 represents a chip-breaker.

1 is a swinging frame having abearing 2, taking about a rod 3, secured in lugs 4 to'the frame of the machine. The frame 1 has a 4'0 planed face 5 for receiving a similar planed end of a chip-breaker support 6, bolts 7 taking into the support through slots 8 in the swinging frame 1, and thereby affording ad- .justment of the same toward and away from the cutter-head. At its lower end the supportcarries a chip-breaker bar or foot 11, ad- .jnstable thereon to and from the cutter-head by means of having bolts 12 take through slots 15 in the support and screwing into the chipbreaker. The support carries a rod 15, upon quire.

which a pressure-lever 16 is adapted to swing. The pressure-lever is also adjustable sidewise with relation to the chip-breaker bar, as by being slid 011 the rod, so as to exert the pressure, as from a weight 17, against any desirable point transversely of the chip-breaker. The pressure-lever preferably has a downward extension 18 and a rearward extension 19. A bolt 21 screws through the lever and is held firmly in place by means of a'set-nut 6o 22. A spring 23 preferably takes about the bolt between the lever and'the support with the end of the bolt 21 normally held out of contact with the support by the spring, the spring thereby serving as a cushion between the pressure-bar or chip-breaker and the weight. A bolt 25, adjustable in the swing ing frame, limits the downward movement of the chip-breaker by having the end of the 5 bolt take against the frame of the machine.

My improved construction permits the chipbreaker to be swung upwardly and slid transversely out of the way, one or both movements being resorted to, as occasion may re- It also permits ready adjustment of the chip-breaker with relation to the cutter head and, further, permits the pressure to be exerted at the point where greatest resistance is desired transversely of the machine by permitting the sidewise movement of the pressure agency.

' I claim- 1. In a woodworking-machine, the combination with a cutter-head, of a chip-breaker therefor, and a pressure device for the chipbreaker, with means for permitting the sidewise movement of the pressure device transversely of the chip-breaker, substantially as described.

2. In a woodworking-machine, the combi- 9o nation of a chip-breaker, means for permitting the same to swing, a lever for the chip breaker, a weight for the lever, a spring interposed between the lever and ,the chipbreaker, and means for permitting the sidewise movement of the lever with relation to the chip-breaker, substantially as described.

3. In a woodworking-machine, the combination of a chip-breaker, a swinging frame therefor, a rod for supporting the swinging 10o frame, means for permitting sliding sidewise In testimony whereof I have signed my of the swinging frame upon the rod, aweightname hereto in the presence of two subserib- IO ing device for the chip-breaker, with means ing witnesses.
