SPECIFICATION forming part of Letters Patent No. 301,841, dated July 8, 1884.

Application led July 25, 1883.v (No model.) Patented in France June 7, 1883, No. 155,908; in Belgium June 22, 1883, No. 61,785; iu England June 2G, 1883, No. 3,17-1,and October 30, 1883, No. 5,157, and iu Germany-June 30, 1883, No. 25,917.

. the saw; and my invention consists, mainly,

'and 2, Fig. 1.

in an improved construction or arrangement of these attachments, as more fully described and claimed hereinafter.

In the accompanyingdrawings, Figure 1 is.

a side view of sufficient of a saw-blade to illustrate the main features of my invention. Fig. 2 is a longitudinal section on the line l Fig. 3 is a side view, and Fig. 4 a longitudinal section, ofa modication; and Fig. 5 is a side view, and Fig. 6 a longitudinal section,of another modification.

The saw and its teeth may be of any' usual form, and the saw itself either straight or circular, those shown in the drawings being straight. In the body ofthe blade, and at equal distances from the cutting-edge, are provided planing-cutters with inclined cuttingedges, the inclines of the two or more cutters which are for dressing the same side being in opposite directions, in order` to produce a smooth surface on the wood. In the construction shown in Fig. 2 these cutters are formed out of the metal of the body of the saw, diagonal curved slots a alternately in opposite directions being provided with enlarged ends b b. The convex edges of these slots between the enlarged ends are formed with beveled cutters, projecting slightly to one side or the other of the blade, as shown in Fig. 2, the set77 being merely sufficient to remove an extremely thin shaving just sufficient to clean off the marks of the saw-teeth. The cutters are so set that their points adjacent to the ends b b do not overlap in the cutting and form ridges. There are four of .these planes shown in Figs. 1 and 2, A, B, C, and D,

the first two being adapted to' cut, on one. l

side of the kerf, and the other two on the other side; or they may be arranged alternately, if

preferred, so long as care is ta'ken to have the two which cut on the same side inclined in' opposite directions to obtain the desired smooth cut irrespective ofthe grain of wood. rIjhis arrangement of making the plane-irons out of the metal of the saw-blade is more es pecially suited for soft woods.

For hard woods I prefer to employ separate detachable cutters, as shown in Figs. 3 and 4, openings F in the form of rhomboids (alternately reversed) being formed -in the sawblade. The rear edge of each opening and the adjoining sides are provided with V- shaped guides, and the corresponding edges of the detachable cutter are V-grooved to t the guides, so that when the cutter (say C) has been inserted in the opening F, as indicated by dotted lines in the lower part of Fig. 3, it can be moved longitudinally of the saw-blade into place. It is prevented from moving laterally by the V-guides, and can be retained from slipping out longitudinally by being tightly fitted, or by copper rivets f f, inserted in countersunk openings formed by corresponding notches in the edges of the opening and of the inserted cutter. Vhen it is desired to withdraw a cutter, the rivets, if used, are

removed and the cutter forced outward by inserting a suitable tool in an opening, d, behind the cutter. .In this construction, as in that illustrated in Figs. 1 and 2, the cutting-edges of the cutters are inclined in opposite directions.

In addition to the planing-tools described I may make use of a scraping or polishing tool, R, to follow the planers, and also a polishing skin or leather or sand-paper, II,which ,I interweave through slits in the saw-blade behind the cutters, as shown in Figs. 5 and 6,

to obtain a more smooth and polished surface..

l I claim as my invention--v 1.l A saw having a series of planing-tools formed on or inserted in the body of the sawblade, and at equal distances from the cuttingedge of the saw, two or more of said tools for dressing each side of the kerf having their In testimony whereofhavesigned mynzune cutting-edges inclined in opposite directions, to this specification in theplesence oftwo Sub 1c substantially as described. i sei-ibing witnesses.
