PLANBR HEAD AND CUTTER.
APPLIOA'IIOI rum) JULY 1, 1904.
JOHN B. FORBES, OF MILL VALLEY. CALIFORNIA.
PLANEB-HEAD AND CUTTER- Specification of Letters Patent.
Patented Feb. 6, 1903.
Application filed July 1,1904. Serial H0- 215,032.
To all whom it may concern:
Be it known that I, JOHN BFonnna, a citizen of the United States, residing at Mill Valley, in the county of Marin and State of California, have invented certain new and useful Iin rovcments in Planer-Heads and Cutters, oi which the following is a spcciiicatron.
My invention relates to woodworking machinery, and more particularly to planerheads and cutters.
The object of my invention is to provide a simple rigid construction in which very thin cutter-blades can he used to furnish it with means for accurately adjusting the cutters and securing them in adjusted positions, to form the head in such a way that wide open threats are provided adjacent to the cutter, making it easily self-clearing and preventing choking and clogging by shavings, and in general to improve the design and construction of such planer-heads in thelines of simplicity,
strength, and efficiency.
'In the accompanying drawings, Figure 1 is an elevation of a planer-head with spiral cutters. Fig. 2 is a cross-section of Fig. 1.
In the drawings, Sdesignates the cutterhead, having proyecting'shaft portions 6 and which is rotatab y journaled and driven 111 any suitable way. This head has a lurality of recesses, the walls 7 and 8 of whic tend to converge outwardly to form a dovetail recess to secure cutters and the securing devices.
In these recesses are fitted the thin cuttens 9, the distanceieccs 12, and the keys or wedges l0, whic fit the conver 'ng surfaces of the cutters and the walls 8. he wall 8 includes a tangential portion 8'. The walls 7 are provided with fine corrugations, and the adjacent surfaces of the cutters are formed with similar corrugations. The interengaging corrugations and ribs thus formed assist in locking the cutters rigidl to the planerhead and at the same time a 0rd along range for very accurate adjustment as such cutters wear. Within reasonable limits, which enable the wedges to get agood bearing on the surfaces of. the cutters, the latter can be worn very narrow and still always be capable of being locked in position.
The screws 11 after assing through the solid head in which t icy are sunk bear against or in the distanceieces, the latter forming racticlillyone wal of the dovetail recess. i'h this construction, and as the holding-screws do not positively enter the wedges themselves, I uard against the possibility of longituihna displacement in use by stop-screws 13 at both ends, which are threaded through the ends of the cutter-head, as shown in Fig. l and bear upon the wedges in opposite directions.
In planers used in woodworking it is a matter of great importance that the planerhead and cutters should be easily cleared and prevented from clogging by accumulating shavings. It will be observed that the distance from the cd s of any cutter across the recess to the peri oral arc of the head forms a wide throat an clearancespace from which all debris is immediately discharged.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A planer-head for woodworking, comprising a cylinder provided with deep eripheral grooves spaced widely apart and avln walls of une ual de th, incombination wit cutters a weihge or ey in each cove of substantially the depth of one we. I, but of less depth than the other, and screw-bolts for securing said wed cs passing substantially tangentially from t he periphery of the head through the wall of greater depth to press said key against the cutter; all constructed and arranged to provide a wide clearancespace or throat between the cutter and the junction of the deeper wall with the periphcry of the head.
2. A planer-head for woodworking, comprising a cylinder, having doe PBIlPhGIfl-l grooves spaced widely apart and aving walls of .unequal depth relatively to the periphery of the c linder, the deeper wall converging outward y towardthe other wall to form a dovetail seat and then extending to the eriphcry tangentially, in combination wit a cutter, a wed e or ey in each dovetail seat and screw-bolls for securing said wedges; all constructed and arranged to provide a wide clearance-space or throat between the cutter and the junction of the angular wall with the periphery of the head.
In testimony whereof I have affixed my signature, in presence of two witnesses, this 9th day of June, 1904.
JOHN B. FORBES.
