CUTTER-HEAD.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed July 15, 1905. Serial No. 269,804.

To all whom it may concern:

Be it known that we, JOHN WILSON WARD and WILLIAM A. WILLIAMS, residing at Bolton Landing, in the county of Warren and State of New York, have invented certain new and useful Improvements in Cutter-Heads, of which the following is a specification.

Our invention, which in its generic nature relates to improvements in cutter-heads. usually termed matcher-heads, of that character mounted upon a vertical spindle and carrying the cutters for effecting the tonguingand-grooving operation for flooring and ceiling material, more especially seeks to provide an improved means for effecting a large number of different adjustments of matcherheads for setting the same relatively to the different thicknesses of lumber to be formed with the tongues and grooves.

Our invention generally comprehends an improved cooperative arrangement and combination of a plurality of washers or disks re- Versibly side for side, individually and collectively, whereby to provide for a large number of adjustments of the cutter or matcher head; and in its subordinate features it consists in the detailed construction of parts hereinafter fully explained, specifically pointed out in the claims, and illustrated in the accompanying drawings, in which Figure 1 is a vertical section of the ordinary type of matcher-head, for which our invention is the more especially adapted, mounted on the drive-spindle with our improvement applied, showing the same adjusted to effect the first or initial adjustment of the matcher-head. Fig. 2 is a similar view showing the parts arranged for effecting a second adjustment. Fig. 3 illustrates how the parts shown in Fig. 2 are arranged to effect athird adjustment. Fig. 4. illustrates the mannerin which our invention effects a fourth adjustment. Fig. 5 illustrates how the parts shown in Fig. 4 are arranged to effect a fifth adjustment. Fig. 6 shows the arrangement of the parts for effecting a sixth adjustment. Fig. 7 shows the parts arranged to effect a seventh adjustment. Fig. 8 shows how the eighth adjustment is secured.

In the practical application of our invention we employ a cup-shaped member 1, whose bottom is of a thickness sufficient to'effect a first or initial adjustment of the matcher-head when the cup is positioned as shown in Fig. 1. This cup, which in a general sense has the function of a washer, in our invention is made of a depth sufficient to receive a plurality of other similar washers and also to provide for a predetermined or maximum thickness, whereby when positioned as shown in Fig. 8 the maximum adjustment or eighth adjustment of the matcher-head is efiected, as hereinafter more fully explained.

2 designates a second disk or washer of less diameter than the cup-shaped washer so it can be readily slipped into the member 1 when it is positioned as shown in Fig. 1. This second washer has one side or surface in a smooth unbroken plane, as designated by 2, while its other side is recessed, as indicated by 2 whereby to form a washer portion of predetermined thickness sufficient when the disk 2 is positioned within the cup 1, as shown in Fig. 2, its thickness and the thickness of the bottom of the cup, as indicated by the broken line a on Fig. 2, produce a combined thickness of washer or filling to effect a second adjustment of the matcherhead. The major thickness of the washer 2 (that is taken through the annular rim 2 thereof) is of such predetermined nature so that when the said washer 2 is turned over, as shown in Fig. 2, its major thickness, combined with the thickness of the bottom of the cup, presents a filling or washer thickness suflicient to effect a third adjustment of the matcher-head.

3 designates a third washer, similarin shape to washer 2, but having its minor and major thicknesses of a greater thickness than that of the member 2, in practice being so determined that when the washer 2 is removed from cup 1 and the member 3 is positioned therein, as shown in Fig. 4, with its minor thickness between the upper end of the spindle S and the lower end of the clamp-screw C, a sufficient washer-filling is provided between the screw C and the spindle S to effect a fourth adjustment of the matcher-head, the major thickness 3 of said disk 3 being such that when the said disk is turned over in the cup 1 and positioned as shown in Fig. 5 a fifth adjustment of the matcher-head is provided for.

By reason of the variable thicknesses of the members 2 and 3 and their relative individual major and minor thicknesses by's'eat'ing, the

thin washer 2 with its annular flange up, whereby to combine the minor thickness-of saidwasher 2 with the major thickness of the member 3, a sufficient filling is provided between the screw C and the spindle S to effect a sixth adjustment of the matcher-head, and when the said thin washer 2 is turned over and positioned as in Fig. 7 the major thickness of said washer 2, added to the major thickness of the washer 3, effects a still greater filling between the screw G and the spindle S, and this provides for a seventh adjustment of the matcher-head. It will be noticed that in all of the adjustments of the washers 2' and 3 mentioned within the cup 1 the major thickness of the cup is through the annular flange portion thereof, and the said major thickness is greater than the combined major thickness of the members 2 and 3 and the minor thickness of the cup, and by reason of such arrangement of parts by removing the members 2 and 3 from the cup 1 and turning the said cup upside down a maximum filling is provided for between the spindle and the screw 0, and thus an eighth adjustment of said head is effected. I

We are aware that a cup-shaped washer has been provided capable of being reversibly mounted between clamp-screw and the spindle for effecting two adjustments of the matcher-head. Our cup-shape member differentiates from what has been heretofore provided in this art, so far as we know, in that it provides for the minimum or first. adjust ment of the matcher-head, the final (eighth) or maximum adjustment of the same, as also a cooperative part of the means for effecting all of the adjustments between the first and the last.

While we have shown a means consisting of three washers, each having a major and a minor thickness, each independently reversible and the three cooperatively adjustable, additional washers, like 2 and 3, might be provided with a cup 1 of proper depth to effect further adjustments by individual adjustments of the said additional washers and a combined adjustment of the same with the Washers 2 and 3.

. By reason of the peculiar construction and combination of the parts described and illustrated the advantages gained in using our invention in handlin stock for tonguing and grooving will be clearly a parent to those skilled in the art to which t 's invention appertains. The individual and collective reversals of the members 1, 2, and 3 readily provide for setting the matcher-head to eight different adjustments capable of working on eight different thicknesses of material and effecting" an accurate operation of tonguing and groovin v Havingthus described our invention, what we claim, and desire to secure by Letters Pat-" exit, is

1, A means for adjusting matcher-head cutters, of the character described; comprising a plurality of washers each having a major and a minor thickness, adapted to be interposed between the bearing portion of the head and the spindle end, said washers being adapted to be independently reversed or collectively reversed with respect to the spindle end whereby to provide for a plurality of adjustments of the matcher-head cutter, one of said washers adapted to contain the remaining Washers as set forth.

2. The combination with a matcherhead cutter, its carryingspindle and its clamp-screw; of a plurality of washers of such construction, whereby with the presentation of one side or surface thereof in the direction of the screw, a different adjustment is obtained from that obtainable by the presentation of the opposite side of the said washer members to said screw, and whereby the presentation of one surface of one washer, and another but difierent surface of another washer relatively to the clamp-screw and spindle effects still further adjustments, one of said washers adapted to contain the re maining washers as set forth.

3. The combination with a matcherhead cutter, its carrying-spindle and its spindle engaging screw of a cup-shaped Washer, adapted when turned with one side to the screw to effect one adjustment, when turned over with the other side to the screw to effect another adjustment, and another washer removably mounted in the cup, having a major and a minor thickness, adapted when turned over to bring its opposite sides to the spindle-screw to effect a plurality of intermediate adjustments.

4. An improved means for adjusting matcher-head cutters, which consists in combination with the matcher-head spindle and its clamp-screw, of a cup-shaped washer adapted to be reversiblypositioned between the screw and spindle, a plurality of washers adapted to be independently seated within the said cup, and collectively interchanged, said washers each having a minor and a major thickness, and having a combined major thickness less than the major thickness of the cup in Which they are held.
