LATHE CHUCK Filed March 22, 1943 INVENTOR ANTON 1J.LAUBY AT TORNEYS Patented Feb. 15, 1944 UNITED STATES PATENT OFFICE 2,341,926 LATHE CHUCK Anton J. Lauby, La Crosse, Wis. Application March 22, 1943, Serial No. 480,014
1 Claim.
My invention has for its object to provide a simple, durable and convenient universally adjustable wood turning lathe, particularly adapted for forming bodies of artificial bait plugs.
Another object of my invention is to provide a drill for centrally boring the plugs, whereby the same are completed for attaching thereto draft lines and hooks.
It is understood, however, that a variet of articles may be manufactured from small chunks of wood in any shape by interchangeable blades. The cutting edges of these blades are shaped to conform'to the finished turned article.
With the above and other minor objects in view, the invention consists in certain peculiarities of construction and combination of parts as will be hereinafter fully set forth with reference to the accompanying drawing and subsequently claimed.
In the drawing:
Figure 1 represents a partly sectional, elevational view of a lathe embodying the features of my invention.
Figure 2 is a cross sectional View of the same, the section being indicated by line 22 of Figure 1.
Figure 3 is a diagrammatic, elevational view of a bait plug formed from a block by the lathe.
Referring by characters to the drawing, I indicates a bed centrally grooved for the reception of an adjustable bearing block 2 and a fixed bearing block 2'. The bearing block 2 has mounted therein a drive shaft 3 carrying at its outer end a multiple pulley 3' and at its inner end a conically cupped chuck 4 for the reception of one end of the block to be turned. It being understood that the cupped chuck is formed with suitable biting ribs 4.
The adjustable bearing block 2 has mounted therein a shaft 5, carrying athrust bearing at its inner end for the reception of a second conically cupped chuck B, which is loosely mounted upon said shaft. This chuck B is in actual alignment with the driven chuck 4 and similar in all respects, being spaced from the same for the reception of a wood chunk or block, as indicated in dotted lines.
The idle shaft 5 is reduced in diameter at its rear end, which extends beyond the bearing block and interposed between the shoulders of the shaft within the bearing block and at the rear end of the same is a coil spring I, whereby said shaft is normally forced toward the opposite chuck. The reduced end of the shaft is provided with a suitable collar for engagement with a pin 8 extending from a hand lever 8. The hand lever is pivotally mounted upon an arm extending from the block 2.
The shaft 5, together with its associated chuck, is bored for the reception of a spindle ID, the inner end of which receives a drill lo the end of which extends into the cup of the chuck.
The outer end of the spindle I0 is linked to a hand lever II, which lever is pivoted to the arm 9 and provided with stops I2, whereby movement of the lever is limited in both directions, said lever is normally held in its idle position by a spring I2 connecting the same with the arm 9.
Transversely mounted between the chucks is a pad I3, which pad is adjustably clamped to the bed I by a screw I4 passing through the slot of said bed and also a slot in the pad. The parts being confined by a hand nut II.
The outer end of the pad has extending upwardly therefrom a hub I3 adapted to receive the end of an adjustable bracket I5, which bracket is held in said adjustment by a suitable binding screw.
The bracket has pivoted thereto an oscillatoiy blade supporting base IS. The upper nd of the base is provided with anchor bolts I6 for confining a blade H, the cutting edge of which extends within the field of the chuck axis and is suitably shaped to conform to the shape of the article turned thereby.
Locking adjusting of the blade I! is effected by bolts l8 and I8, whereby the proper angle of said blade is effected and secured.
As noted in Figure l of the drawing, the supporting base I6 has a horizontally extended arm terminating in a gripping handle, whereby said base is manually rocked upon its pivot causing the cutting edge of the blade to be moved in or out with reference to the work I9, as indicated in dotted lines in Figure 2, and also in the detail, elevational view shown in Figure 3 of the drawing.
From the foregoing description, it is apparent that the chunk or block to be worked upon is inserted betwen the chucks and in doing so, the spring interposed in the shaft 5 is manually moved backward by the handle 8 and upon the release of the handle the spring 'I will firmly cause the block to be locked and rotated by means of power applied to the driven. chuck, while the idle chuck 6 will revolve loosely upon the shaft.
During this operation the supporting base l6 of the blade is gradually moved inward toward the axis of the chuck by a manipulating handle and the movement in either direction of the base I6 is limited by upper and lower set screws 20 and 20, which set screws engage the arm portion of the base.
It is apparent that in the event it is desired to bore the turned article, as is indicated in Figure 3 of the drawing, the operator simply shifts the handle I I in opposition to its spring, whereby the drill ID will be caused to bore a central hole through the plug.
While I have shown and described my invention as to details, it is understood that I may vary such details within the scope of the claim.
I claim:
A drilling machine comprising bed supported axially aligned bearing blocks, a fixed driven chuck mounted in one bearing block, a spring opposed bored idle shaft mounted in the opposite block and extending rearwardly thereof, a reciprocative conically cupped chuck loosely mounted upon the front end of the shaft, a nonrotative reciprocative drill receiving spindle guided in the shaft bore, a hand lever for actuating the drill receiving spindle, and a hand lever engaging the rear end of the shaft for shifting the same in opposition to its spring control.
