'enerall'y comprises a table 1, provided with -'uitable frame members 2, whereby the table s supported a convenimit height above the ground for the operator. A bracket 3 is located at one end of the table and is pro- I V 1- extending downwardly below the table 1 and secured in position by suitable clamping members 5 and 6 cooperating withthe end frame members 2. The upper portion of the bracket 8 is bifurcated and socket member 7 is pivotally mounted between the arms 8 of the bifurcated portion ona pin 9 which extendsthrough the arms Sand atongue 10 of the socket 7 A shaft 11 is carried by the head 12 of the socket 7 and a frame 18 is pivotally mounted on the shaft 11 by means of lugs 14- through which the shaft 11 passes. A tool shaft 15 is rotatably mounted in lugs 16 provided at the other end of the frame .13 and is provided with a pulley 17 by means of'which itmay be rotated. The lower end of theshaft 15 terminates in a tool holder 18 within which is supported asuitablecu ting tool 19. A lever-20 is pivotally supported at the upper end of theshaft 11 by a collarlll and is connected to the shaft 15 by means of a link 22 which receives a threaded rod 23. As best shown in Fig. 7, the rod 23 terminates in a ball as which isseat-ed in a socket 24- in the shaft 15. The lever 20 terminates'in a handle portion, by means of which it may be turned about its pivot to move the shaft 15 vertically with respect to table 1, the ball and socket joint permitting universal movement of the rod 23. Steps l5 are provided to limit the movement of shaft 15. I

Driving pulleys 25 and 26 are rotatably mounted on an extension of the pivot pin 9 and the pulley 26 is connected to the pulley 17 by means of a continuous belt 27 which passes over a pair ofguide pulleys 28, that are mounted on brackets 2 carried by the head 12, and asecond pair of pulleys 29 that are mounted on a bracket 29 carried by the shaft 11. The pulley is connected to any suitable source of power, not shown. i

As best shown in Fig. 2, the head 12 of the socket 7-is provided with'a pair of ears 30, between which is rotatably mounted a worm 81. V The worm shaft 32-extends beyond the ears 30 and each endthereofis provided with a squared portion for receiving a suitable opera-ting handle 3%, by means of which the worm 31 may be turned. The worm 31 is in mesh with a plurality of teeth 35, provided on one of the arms 8 of the bracket 3, the teeth being arranged concentrically about the axis of the pivot pin 9. Turning of the worm 31 will therefore cause the socket 7 together with the tool frame 13, to be swung about the axis of the pin 9, as indicated in dotted lines. The pin 9 is provided at one end with a fixed collar 36 in engagement with the pulley 25 and at the other end with a lock nut 37, by means of which the tongue 10 of the socket 7 may be clamped between the arms 8 of the bracket 3, in order to secure the tool frame 13 in position after it has once been adjusted by means of the worm 31. The shank 4 of the bracket 3 is provided with an arm 38 which terminates in an internally threaded portion 3S through which extends a screw shaft 39. 'The shaft 39 is connected by bevel gearing 10 to a handle 41 by means of which it may be turned in order to cause the bracket to be moved vertically by reason of the connection between the shank 1 and the screw shaft 39. In this way the bracket 3 together with the entire tool carrying structure can be located at any height above the table 1 and then be secured in position by the clamping members 5 and 6.

From the foregoing, it is apparent that 1 have provided a universal mounting for the tool holder 18, whereby it may be positioned in any desired relation with respect to the table 1. In the first place, the frame 13 may be positioned at any desired height above the table 1 by adjustment of the shank at through the screw shaft 39. The axis of rotation of the tool shaft 15 may then be fixed at any desired angle by turning the worm 31. After the frame 13 has been positioned as described above, it may then be swung about the axis of the shaft 11 and lastly, the tool shaft 15' maybe moved longitudinally on the frame 13 by means of the lever 20, a spring 20 being provided to assist in raising the lever 20 from its original position. In this way, the tool 19 may be initially positioned with any desired relation to the work which is adapted to be controlled by my improved work holding and feeding device, which will now be described.

Referring now to Fig. 3, the table 1 is provided with a slot 42 along the sides of which are provided rails 13 for slidably sup porting a plate 44, so that its top is flush with the top of the table 1. A. work sup port is carried on the plate 1 and is provided with rollers 415 and with a foot 16 through which it is secured to the plate at by a bolt d7 coacting with one of several holes 428 provided in the plate 44.

A work holding and feeding device is also carried on the plate 44 and as best shown in Figs. 4 and 6, comprises a triangular shaped bracket formed by spaced plates 19. Thebracket is pivotally mounted on a pin passingthrough the plates and held in position by a clamp 51 securedtothe plate as. Atoothed wheel 52 is rotatably mounted between the plates 49 and each plate 49 is provided with a slot 53 for receiving a worm 54L which is in mesh with the wheel 52. The worm 54: is carried on a shaft 55 mounted in bearings 56, one of which is adapted to be engaged by a disk 57 eccentrically mounted on a pin 58. The disk 57 is provided with a handle 59 by means of which it may be turned to engage the bearing 56, and thereby turn the bracket about its pivot 50 until the wheel engages the work and forces it against the support 45. An adjustable stop 60 is carried by the plate 441 to limit the pivotal movement of the bracket and thereby prevent the wheel 52 from cutting too deeply into the work.

The shaft is provided with a handle 55 by means of which the woun 5 1 may be turned, and it is obvious that when the teeth of the wheel 52 are held in engagement with the work, turning of the worm 5 1 will cause the work to be moved either toward or away from the tool 19, as shown in Fig. 3. The plate as is provided with a handle 14 by means of which it may be moved back and forth on the rails a3 in order to properly position the work. The work support 15 is adapted to be positioned at any desired angle on the plate 44, so that the line of movement of the work as it is fed will be substantially tangential to the periphery of the cuttting tool, or in any other desired rela tion thereto. The work support 45 may also be shifted on the plate a l and secured in a new position by employing the other holes 43.

Referring again to Fig. 1, a circular saw 61 is rotatably mounted in bearings 62 provided on an arm 63. The arm is pivotally mounted on a pin supported at one end of the frame and the other end of the arm 63 projects beyond the opposite end of the table 1. its best shown in 8 and 9, the arm 63 extends between the flanges 65 of a pair of vertical frame mere-- hers 66. he arm 63 is adapted to be clamped between the flanges in any desired position, by means of a clamping member 67 which embraces the flanges and is adapted to force them together by means of a stud 68 provided with a handle 69. in this way the saw 61 may be so positioned that its periphery will extend through a slot 70 provided in the table 1 the desi ed amount. The lower portion the clamp 67 is provided with a pin '71 for support ing the arm 63. The shaft 72 of the saw 61 is provided with a pulley 73 that is connected to driving motor 741- by means of a belt 75 passing over pulleys 6 and 77, mounted. on a bracket 78.

Referring now to Fig. 5, a plate 79, similar to the plate 1 1 is provided with a work support 80, to which it is secured by means of a bolt 81 coacting with one of several holes 82. A screw shaft 83 is rotatably mounted on a lug 8d extending upwardly from the surface of the plate 79 and is adapted to be turned by means of a handle 85. The end of the shaft is provided with a work engaging head 86 which isadapted to hold the work firmly in engagement with the support 80. The work is adapted to be moved with respect to the saw ing the plate 7 9 011 the rails 43 and the sup port 80 is adapted to be secured in any desired position to obtain the proper angle r of cut, when the work is engaged by the saw.

From the foregoing, it is apparent that I have provided a wood working machine that is particularly adapted to perform a large number of operations associated with wood working, Thus, a given piece of rough stock may first be planed by the tool 19 by the use of the work feeding device, it being obvious that any desired depth of cut may be obtained by properly positioning the plate 44L It is also obvious that the axis of the tool 19 may also be changed to plane a bevel surface, if so desired. A boring tool may then be substituted for the planing tool and holes drilled into the work at any desired angle by manipulating the handle 20 and raising and lowering the tool shaft 15. It is also obvious that many other operations may be performed upon the work by employing various other tools and by moving the work holder to different positions. The saw 61 may also be arranged for any desired depth of cut by clamping the arm 63 between the flanges 65 so that the saw will project above the table the re quired amount. The work may then be fed to the saw by means of the plate 79 as previously described.

It is obvious that my machine is adapted for a great variety of work and that it may be advantageously employed wherever wood working is being carried on in place of the cumbersome carpenters benches and hand tools heretofore employed.

hile I have shown my universal tool holding frame as applied to a wood work ing machine, it is not so limited, for it is obvious it may as well be applied to other machines employing a rotating tool, and I desire therefore that only such limitations be imposed thereon as come within the scope of the appended claims.
