PATENT OFFICE THOMAS 1. WHITE, 01' ELMIBA, NEW YORK WOODWORKING MACHINE Application filed Iarch 31, 1930. Serial No. 440,383.
This invention relates to a wood working machine and is more especially a machine for mitering, ripping, and cross cutting wood although it can also be used as a jointer.
5 An object of the invention is to provide a diametrically slotted disk mounted for rotation within agraduated circle, this disk carrying cutting mechanisms all of which can be adjusted angularly at will to bring the 1 saw of the mechanism, which projects through the slot in the disk, to any desired angle relative to the stock to be cut.
Another object is to provide a mechanism having means whereby the saw can be fed into 15 the stock by manipulating a foot of the user, thereby leaving'both hands free to hold the stock while it is being cut.
A further object is to provide a machine of this character which is simple and compact in 20 construction, can be easily and quickly set to cut at a desired angle, and can be operated with little effort.
With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown.
In said drawings,
Figure l is a plan view of the machine, some of the-positions to which the mechanism can be adjusted angularly being indicated by broken lines.
Figure 2 is a front elevation of a portion of the apparatus.
Figure 3 is a section on line 3-3, Figure 2.
Figure t is a section on line 4-4, Figure 1.
Figure 5 is a view partly in vertical section and partly in elevation of the rotatable structure Referring to the figures by characters of reference, 1. designates a frame supporting a stationary table top 2. This top has an upstanding guide strip 3 secured thereon and a substantially circular opening 4 is formed 1n the top. This opening extends under the strip 2 and has its wall removed at the back of the table. In the opening is seated an arcuate bearing stri 5 the ends of which are flush with the bac edge of the table. Thls strip is graduated in degrees or fIEI CtIOIIS of degrees and is held against rotation by any suitable means. Certain of thegraduations can be provided with designating characters arranged on the table 2 adjacent to the strip as shown.
A disk 6 is fitted snugly in the space defined by the strip or plate 5 and has a diametrical slot 7 extending close to the edge of the disk. An index or pointer 8 is connected to the disk and is adapted to register with any of the graduations on the strip- 5 thereby to indicate the angle at which the slot 7 is disposed to the guide strips 3. As shown in Figure 4 the ring or strip 5 is held against rotation by a set screw 9 extending from the front edge of the table 2, the inner end of this set screw bearing against the marginal portion of the disk 6 thereby to hold the disk 6 against rotation after it has been set in a desired position. The screw 9 can be provided with a head 10 to facilitate rotation thereof.
Mounted in the frame 1 below disk 6 is a lower table 11 on which a sweep 12 is adapted to swing horizontally, this sweep being connected to table 11 by a ball bearing pivotal support 13. An arcuate handle it embraces the front end of the sweep and is secured to the sides thereof. Thus a portion of the handle is always located where it can be conveniently reached for the pur pose of swinging the sweep about its pivotal connection 13. Spaced standards 15 are fixedly connected to the sweep and also to the bottom of the disk 6 at opposite sides of the slot 7 and by providing these standards the disk and the sweep are caused to rotate together about a common axis, it being understood that the pivotal connection 13 is in line with the axis of rotation of the disk 6.
Secured to and extending longitudinally of the sweep 12 are parallel guides 16 on which are slidably mounted sleeves 17. These sleeves are secured to and extend downwardly from a slide 18 on which are secured u standing guides 19. These guides are slida ly engaged by a cross-head 20 in which is journaled a shaft 21 and secured to this shaft is a circular saw 22 that works within the slot 7 and rotates in a plane extending longitudinally of .the slot.
A pulley 23 is rotatable with shaft 21 and is adapted to be driven by a motor 24 mounted on the slide 18. Any suitable means, such as belt and pulley mechanism indicated generally at 25, can be employed for transmitting motion from the motor to the shaft 21.
A feed screw 26 is mounted for rotation in slide 18 and extendsvupwardly into and engages the crosshead 20. A gear 27 rotates with the feed screw and is adapted to be actuated by another gear 28 secured to a shaft 29 journaled in suitable bearings 30 1 rovided on slide 18. This shaft 29 can e rotated by means of a crank 31 and, when thus actuated, will rotate the screw 26 so as to raise or lower the c'rosshead 20 and move the saw 22 upwardly or down wardly relative to the disk 6.
Connected to the slide 18 and to "the sweep 12 is a spring 32 which serves to hold the saw normally retracted away from the guide strip 3 so that it will be in the position indicated by broken lines in Figure 4. When it is desired to move the slide 18 against the action of the spring a pedal 33 is pressed by one of the feet of the operator. This pedal is suitably mounted in the rear ortion of the frame 1 as indicated at 34 and is connected by a link, rope, or the like indicated at 35 to an arm 36 radiating from a rock shaft 37 On the rock shaft 37 is secured a relatively large pulley 38 to the periphery of which is attached one end of a flexible element 39 which can be in the form of a chain, rope or the like. lhe other end of this flexible element passes upwardly through the pivot 13 which can be tubular as shown particularly in Figure 5 and thence over a guide pulley 40 to the back end portion of the slide 18. Obviously when the pedal is depressed it will cause the shaft 37 and pulley 38 to rotate and this will pull on the slide through the connection 39. V
In practice the saw 22 is adjusted upwardly a suflicient distance to cut through the stock S on table 2 and disk 6. The guide strip 3 is stationary and the stock is placed therea ainst. Before this is done, however, the dlsk 6 is loosened and, by means of handle 14, said disk and the parts connected thereto are rotated until the slot 7 is brought to the desired an 1e relative to strip 3 for producing a cut at the proper angle. After this adjustment has been effected and the disk 6 held by means of set screw 9, the stock will be cut into.
Obviously by means of this apparatus, any desired miter can be cut or the saw can even be brought to position to cut straight across the stock or to rip the same. The adjustment can be effected very quickly and accurately and as the saw is shifted by pressure of a foot, both hands of the operator are left free for holding the stock while it is being cut and for removing it from the table 2.
As an added improvement the table 2 can be provided with a j ointer 41 working within an opening 42 and the shaft 43 of the jointer can be driven by a belt 44 adapted to receive motion from the motor 24 when the shaft of said motor is swung to position parallel with shaft 43.
What is claimed is:
1. In a machine of the class described a table having a fixed stop, a slotted structure mounted for rotation in the table and beneath the stop, said structure constituting means for supporting stock in engagement with the stop, a sweep connected to and rotatable with the said structure, a slide rotatable with and mounted on the sweep, a saw carried by the slide and adapted to Work within the slotted structure, means on the slide for actuating the saw, yielding means for holding the slide normally at one limit of its movement, and means under the control of an operator for shifting the slide toward the other limit of its movement, said last named means including a foot pedal, and a connection between the pedal and the slide, said connection including a flexible member extending through the axis of rotation of the slide.
2. In a machine of the class described a table, a slotted structure mounted for rotation relative to the table and constituting means for supporting stock, a sweep connected to and rotatable with said structure, a slide rotatable with and mounted on the sweep, a saw carried by the slide and adapted to work within the slotted structure, means on the slide for actuating the saw, and means under'the control of an operator for shifting the slide toward one limit of its movement, said last named means including an operating element, and a connection between said element and the slide, said connection extending along the axis of rotation of the slide.
:' In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
