UNITED STATES PATENT QF-FICLE- WOODWORKING MAGHINE.

Application filed April 12, 1922'. Serial in. 551,892.

My invention relates to wood-Working machines. It has for its object to provide a construction in which the machine combines a cross cut saw, a rip saw, and a jointer, the machine being'formed so that the several operations mentioned may be'carried on in the same machine, and the several parts arranged to combine strength, stability and :smplicity; and in which also simple and efiicientmeans will be provided for changing the position of the work-table so that it may be readily adjusted for coaction with either the cross-cat saw or rip saw, and which may also be readily adjusted to stand at an angle or inclination to the saw for facilitating the work under desirable conditions. To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features of construction'and combination of parts hereinafter described and then sought to beclearly defined by the claims, reference being had to the accompanying drawings forming a part hereof. and in which a 'Figure 1 is a plan view of the machine, the position of the motor for operating the :ip saw being shownin dotted lines;

Figure 2 is a side elevation of the machine, tilted positionof the work table being shown, in dotted lines;

Figure 3, is an end elevation of the machine. v

In the drawings the numeral 1 designates the frame of the machine consisting of the metal side members 2 connected one to the other by cross-bars 3 which may be wooden bars bolted to the side members, the side *membershaving extending brackets 1 to re ceive the work-tablesupporting and adjusting means, and the si'de'members supporting a saddle 5 extending from one side member to the other, preferably midway of the two members, and from which forwardly extends a bracket armfi carrying oneend a jour+ "nal-bearing 7 for the rip saw sha t, the other journal bearing 8 for said shaft preferably being formed as a part of the saddle 5. From the saddle 5 is supported an upri ht post 9, the lower end of which passes through a split collar or sleeve 10' preferably attached to or formed as a part of a rib or web 11 of the saddle and formed with threaded ears or lugs 12 to receive the threaded end of a rod 13 provided with an operating handle, which may be a hand wheel 14:, so that the post may be clamped in position by contract ing'tlie split collar. A shoulder 15 formed by reducing the diameter of the post, or

otherwise, rests upon a collar '16 which encircles the' post and maybe'seated on the saddle 5 or other part of the machine frame and is formedwith a finger 17 through which passes a pin 18 adapted to engage any one cutting either square or .at 'any angl'eto the right or to the left for which theadjiistment is made; the slidable pin passing through the finger and entering one Of'tlle perforations in the boss will hold the post at the adjustment given thereto. If acut at an angle other than that provided for by the perforations in the boss 'is'd'esire'd,'the same can be effected by removing the pin and loosening the split collar 10 by manipulation of the threaded rod 13 and after obtaining the ad justment then tightening the split clamp on the rotatable post so asto hold the post to its adjustment. It is obvious that the post may be held to its adjustment by the split collar or sleeve'an'd the threaded operating rod without the asset the pin in conjunction with the index finger and perforations in the boss, and that if'the split collar or sleeve be left in an unclamped condition the index finger and pin'for entering the perforations of theboss may be reliedon for holding the post to its adjustment. In either 'case'the indexisca'le will indicate the extent of adjustment made. The collar 16 from' which the'index finger extends may be secured to the post b a set screw 21.

I The upper end of post 9 carries a laterally extending bracket arm 22 which is supported from the post by a hub 23 formed with side hearings or boxes 24 and [at its outer end carries a cross-head 25 formed with side hearings or boxes 26, said bearings or boxes 24 and 26 serving to support slide rods 27 V which constitute a sliding carriage orbeam that supports at one end a motor 28, preferably an electric motor, for driving the saws and a o1nter of the machine, said moa hand grip for reciprocating the carriage and also provided with journal bearings 31 for the arbor shaft 82 or the cross cut saw 83. If desired, the journal'boxes 52 i and 26 may be provided with roller bearings 3 L for the carriage rods or beams.

The saw arbor 32 carries a pulley from which a drive bolt 34 extends to and around a double cone pulley 35 mounted on u.ie shaft 36 of the motor 2.8-.-

The ri saw is designated'by the numeral 37 and is mounted on'the shaft or arbor 38 journaled in the boxes 7 and 8 provided 'desm-ned to tableis used without any chan e in posi-' tion of the table except to raise or lower it to bring it within the proper plane for the particular saw tobe used.

The work table, designated by thenumeral 41 is supported-from the brackets 4 by screws 42 passing through sleeves 43 and provided with nuts lA ,fittingbetween the upper and lower members of each pair of sleeves, each nut being provided with a bevel gear 45 'with which mesh bevel gears 46 mounted on a counter shaft 47 having its ends in bearings l8 formed on the sides of sleeves Band provided with a hand wheel 49 toturn the counter shaft to raiseor lower the screws and the table"supportedithereby. When the cross cut saw is in use the table is in the elevated position indicated in Figs. 1 andfi, and. when the rip saw is to be used the table is lowered by thezscrews 42 so as to bringj it into the proper plane for action of the rip saw. The worlrtable is connected with the screws 42 "by means of segmental sockets, 50 attached to a plate 51 secured to the underside oi"- the table and which receive rails or tracks 2 provided withdepending ears orlugs '53 which fit within, the bifurcations otheads or m mbers 54 secured to the upper ends or the screws &2 and'held therein by threaded bolts 55 passed I through the headsa'nd rail lugs andtightenedby handnuts 56 so as to clamp the lugs of the rails and hold the work table in its adjusted position, either horizontally or at an inclination as desired. The lugs 53 are formed with tail extensions 57 through which screws 58 I are passed with their ends adapted to bear against the heads 54 and they serve as stops to check the movement of the table when changed. from an inclined to a horizontal position and thus insure the prompt leveling of he table when changing its-position.

The work table is also capable of adjustment towards and from the post 9 by sliding it alongits railsISQ or Uracl; and looking it to such adjustment by a set screw '59 passing throu one of the segmental sockets 50 and bitin the rail,

A jointing device, designated by the nu' me'ral 60, is shown in conventional way as any approved construction of such device be used. This is supported on a platio. 61, and its drivingshaft 62 is provided with a pulley 63 from which a belt 6% will extend to and aroun'd'a pulley 35 on the iaft oi the motor when he motor is shifted o the position shown in dotted lines in Fig '1 or t e drawing.v In this position'the be operated at Pic-F h and the rip saw may time. rriage which carriesthe motor 28 cut saw may,' ii desired, be locked at any particular point in its length of travel, by means of a'set screw 65 passing through one of the boxings 24 and made to bite against the rail 270i the carriage,
