' To all whom it may concern: 1

Be it known that I, MACKINTOSH Huron- InsoN, a subject of the King of Great Britam, residing at Toronto, in the Provincepf Ontarlo and DOIlllIllOIl of Canada, have 1nvented certain new and useful Improvements in Woodworking-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled' inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. r

My invention relates to wood working machines, adapted, among other uses, for sawing in mitering, cross-cutting, dadoing and kindred operations, and adapted to have its motor coupled-up with a machine for ripping, for sandpapering and for other purposes so that combined operations can be carried out by operatively connecting-up with the sawing machine the necessary parts for carrying out the other operations The object of the present invention is to improve various features of the machine so as to afford greater ease and facility of operation in its various parts, and also increase I its stability, and durability and compact ness.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then sought to be clearly defined by the claims,

reference being had to the accompanying drawings forming a part hereof, and in which porting bracket, looking carries the. saw spindle;

Fig. 7 is a side view of one of the eccentric spindles for supporting the ball bearing rollers which sustain the siderods of the traveling carriage;

Fig. 8 is an end view of the spindle;

Fig. 9 is one of the sustaining rollers,

shown in cross section;

Fig. 10 is ..a side elevation of a portion of the machine illustratin the motor and the carriage, and the positlve lock for angular adjustment of carriage and saw;

ing horizontally disposed upper and lower' members 4 and 5 and

end members

6 and 7 is disposed centrally beneath the table, the

member 7 being extended diagonally beyond the end of the table where the column 3 is located so as to brace the table and column and afford greater stability at the point where the column and the parts which it sustains are positioned. The base of the column rests in a collar 8 secured to the member 5 and is encircled by a split sleeve 9 attached to or made as a part of the member 4:,

the sleeve being formed with threaded ears 10 through which pass the threaded end of a rod 11 provided with a hand wheel 12 so that, if desired, the sleeve may be made to clamp to column to hold it to any circular adjustment that may be given thereto for some desired "angular adjustments of the saw that will be carried by its mandrel on the traveling carriage that 'willbe sustained from the column.

'On the column, above the tabletop, is

bracket for supporting the traveling carriage in which the saw is mounted. This bracket consists of a sleeve 13 encircling the column and formed with recesses 14; which receive steel guide bars 15 riveted or otherwise secured to oppositesides of the column so as to permit of vertical adjustment of the carriage to regulate the depth of cut of the saw mounted on the carriage. The

bracket sleeve has side sleeves 16 to receive side rods of the carriage and also a horizontally extending member 17 which at itsare bored out and fitted with races 21 be-- tween which are fitted ball bearings 22, thus affording anti-friction bearings between the rollers and their spindles 23 which pass through the rollers and are supported in the boxes 18 and held in position therein by set screws 24. To maintain the carriage level and insure an even uniform pressure of the side rods of the carriage on the rollers under varying conditions, provision is made for vertical adjustment of the rollers, so that they maybe elevated or lowered as found desirable, by turning or forming the spindles eccentrically as illustrated. Thus, to elevate or lower the rollers so as to obtain the desired pressure between the rollers and I ment of the carriage to insure the best work.

The carriage is made up of the side rails or rods 25, which are preferably made of steel, and a connecting cross-head 26 which .is formed with sleeves 27 to receive the side rods which are secured within the sleeves 27 to receive the side in any suitable manner so that the cross-head and the rails or rods through a belt 33 or other means connected with the shaft of a motor 34, electric or otherwise which may be suitably supported on the opposite end of the carriage so as to be moved with the carriage.

To adjust the depth of cut of the saw the bracket which supports the carriage is adusted vertically by means of a threaded rod 35 threaded in the bracket extension 7, therod extending through a-guide brace bracket 36 and having a bevel pinion 37 at its upper end with WhlCll pinion meshes another pinion 38 on the end of a shaft 39 having a hand wheel 40 so that through such means the bracket and saw carrying carriage may be vertically adjusted to regulate the'depth of cut of the saw. a

For the purpose of holding the saw so as to cut square, or at an angle of 45 degrees, or at right angles, either to the right or to the left, I provide the post 3 with a collar 41 and provided with apertured ears 42, preferably five in number, adapted to receive a pin 43 which will pass through the desired car and enter a hole 43 form d in' a suitable part of the table frame of the machine, for instance in the central rail 4, so that the post will be positively held by the pin to the adjustment which will securethe saw in po sition to cut either square or at the angle desired to which the adjustment is made. The collar will be held to the post by a set screw 44, preferably for cutting square in the direction from front to rear of the table. By removing the locking pin and turning the post to bring another ear to register with the pin receiving hole in the table frame and then inserting the locking pin, a cut in the direction desired may be obtained either to the right or left and at the angle or extent of adjustment provided for. The top of the table will be preferably recessed to receive the collar. If a cut at an angle other'than that provided for by the positive locking collar is desired the same may be effected by removal of, the locking pin, then turning the post to the position desired and then tightening the encircling clamp-ring 9 by means of the screw rod 11, so as to hold the post by frictional clamping action instead of by the positive lock afforded by the collar and locking pin. At other times when not serving as a clamp, the ring 9 serves as a brace to the post.

The saw arbor and the driving motor both being fixedly attached to the traveling carriage there will be no slackening or disarrangement of the belt or driving connection between the motor and saw mandrel in either the vertical or'horizontal adjustment of the carriage and saw; the rear extension of the carriage supporting bracket with-the bear ings for the side rods of the carriage relieve the side rods of the strain of weight of the motor carried by the rods and also make the movement of the carriage and parts 'supported by it easier, smoother and under more uniformpressure'than otherwise would be the case; the rigidity of the column in relation to the work table is greater by reasonof the holding clamp provided, and also by reason of the centrally disposed bracing frame beneath the table top.

The numeral 45 designates an electric switch that may be used with electric con ductors for supplying the current for runnmg the electric motor for driving the saw one end and provided with bearings supporting a saw mandrel.
