WOODWORKING MACHINE.

Application filed- December 21, 1921. Serial No. 523,872.

To all whom it may concern:

Be it known that I, GEORGE A. MANeAs, a citizen of the United States, residing at Wooster, in the county of Wayne and State of Ohio, have invented a new and useful Woodworking Machine, of which the following is a specification.

This invention relates to improvements in wood working machines and has for its objects to provide a machine adapted fn: cross cutting or rip sawing, planing, ointing and the like, and which may be easily and quickly adjusted to the various posltions, heights and angles required for the different classes of work which may be performed with the machine.

The above and other objects may be attained by providing a suitable supporting frame upon which is mounted a vertically adjustable table arranged to bet1 lted at various angles, a turn table being pivotally mounted adjacent to said table and having a sliding bed mounted thereon which carries a motor and a tool spindle driven thereby upon which the saws or other tools may be carried, the bedbeing arranged to be slidably moved at any desired angle to the table or parallel therewith.

A preferred embodiment of the invention thus set forth in general terms is illustrated in the accompanying drawings. in which- Figure 1 is a plan view of the machine adjusted for the rip sawin or planing;

Fig. 2. a front elevation of the same;

Fig. 3, an end elevation of the same;

Fig. 4. an elevation of the opposite end of the machine showing the same adjusted for cross cut sawing;

Fig. 5, a plan view of the same; and

Fig. 6, a front elevation of the same;

Similar numerals of reference indicate corresponding parts throughout the figures of the drawings.

The supporting frame comprises the end members 1 connected together near their lower ends by the tie bars 2 and braced at their upper portions by the brace bars 3. each of said end members having an upward extension 1 upon its rear side, a vertical guideway 5 being formed upon each of said extensions.

A pair of screws 6 are threaded through the end members 1 and arranged for vertical movement therein, each of said screws being provided at its upper end with a beveled pinion 7 meshing with a similar pinion '8 upon the horizontal shaft 9 which is journaled in the brackets 10 mounted for vertical movement upon theguide ways 5.

A crank or handle 11 is fixed upon one end of the shaft 9 for the purpose of rotating the same in order to raise or lower the brackets 10 through the screws 6. Each of the brackets 10 is provided with a pair of spaced bearing portions 12 within which are slidably located the rods 13 arranged to be held in any desired adjusted position by the set screws 14.

A block 15 is carried by each of the rods 13 and is provided with a segment 15* having a rib 15 A clamping screw 16 is located through the rib 15 which is received within the curved slot 17 of the adjacent quadrant 18 upon which the work table 19 1s carried. The table may thus be tilted at any desired angle upon the segment 15 and may be moved laterally upon the guide rods 13.

The work table is provided with a vertically adjustable portion 20 arranged to be adjusted by means of the hand wheel 21 for the purpose of using the device as a jointer. The body portion 19 of the table is provided with the inclined notches 19, into which the inclined lug 20 of the adjustable portion 20 are received. The screw 21 upon the hand wheel 21, is located through a suitable threaded bearing inthe body 19, and engages the adjustable portion 20 of the table for raising or lowering the same. The top of the work table is formed of two separable sections 20, one of which is mounted upon the body portion 19 of the table frame, the other section being mounted upon the adjustable portion 20 thereof. Each of these sections is preferably mounted for longitudinal adjustment upon the frame of the table, the shouldered locking screws 44, being extended into the table sections 20 and through elongated slots in the body portion 19 and adjustable section 20 of the table.

A detachable wooden shelf 22 is arranged to be placed over the work table when the machine is to be used for cross cut sawing or the like, said shelf being provided with a retaining ridge 23 against which the work may be held. When the machine is to be used as a rip saw or jointer, a ripping fence 24 is provided for attachment at one side of the table. This ripping fence is carried by a pair of slotted brackets 24 adjustably connected to the brackets 24 by means of h I the screws 24). A tilting adjustment or" the fence is provided by means of the screws 243. which ivotally connect the angular ears 24 of tiie fence with the brackets 24.

A turn table 25 is mounted upon the bed 26 supported at the upper ends of the side frames 1, this turn table being provided with graduations as shown at 27 for the purpose of easily determining the angleat which it is set, a suitable clamplng devlce such'as' shown at 28 being provided to lock the turn table in any desired position.

the position best shown in Figs. 4 and 6 mid the shelf 22 placed thereon, the turn table being turned to locate the sliding carriage .at right angles to the work table or at any other desired angle thereto.

It will also be evident that the sliding carriage may be turned at any angle to the work table and the turn table locked in this position to provide for sawing at any angle necessary. The work table may also be tilted upon the quadrants 18 and locked-in any inclined position by means of the locking A carriage 29 is slidably mounted upon screws 16.

the turn table, being located above the roll- .ers 30 and beneath the rollers 31 carried by the turn table. Guides 32 are provided upon 0 posite sides of the turn table to guide t e carriage as it is moved longitudinally by means of the handle 33.

A motor 34 is mounted upon the carriage 29 and a spiral gear 35 is carried upon the shaft 36 of the motor, meshing with a spiral pinion 37 mounted upon the mandrel 38 which is located beneath the motor and extends to the opposite side of the machine. These gears are preferably enclosed in a housing filled with oil. The cross cut saw 39 is adapted to be placed u on the mandrel in the position shown in igs. 4:, 5 and 6, the rip saw 40 being arranged to be carried upon the mandrel in the osition best shown in Fig. 1. It will be, 0 course-understood that either of these saws may be used, or any suitable planing tool may be carried upon the mandrel, dependingupon the kind of work to be performed by the machine. 4

In operating the machine for rip sawing or jointing, the work table is raised to the position best shown in Figs. 2 and 3, the shelf 22 being removed and the turn table locked in position as best shown in Fig. 2, locating the carriage 29 parallel with the table. In this position the rip saw 40 will project upwardly through the slot 41 in the table top. The planing orjointing tool will, in the same manner, project through the slot 42.

It is to be understood that in using the device for rip sawing, jointing, etc., the sections 20 of the table top must first be separated to permit the tool to be received therebetween after which .they are returned to the normal position. A look 46 is provided for locking the carriage against movement when in this position. The lock 46 may be any usual and well known form of latching means, and as illustrated co-m prises a lever handle mounted upon the carriage and provided with a bolt adapted to engage a suitable portion of the turn table to lock thecarriage against movement thereon. When it is desired to use the machine 'for cross cutting, the table is lowered to i I claim 1.
