Specification of Letters Patent.

Patented Aug. 14., 1917.

Application filed November 22, 1916. Serial No. 132,850.

To all whom it may concern:

Be it known that I, CARL A. WAGNER, a citizen of the United States, residing at Danville, in the county of Boyle and State of Kentucky, have invented certain new and useful Improvements in Turning, of which the following is a specification.

The object of this invention is to provide improvements in the art of turning wood or other material.

This and other objects of the invention will be illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the drawings,

Figure 1 is a side elevation of a lathe equipped for carrying out my invention.

Fig. 2 is a vertical section on the line 2 2 of Fig. 1.

Fig. 3 is a horizontal section on the line 3 --3 of Fig. 2. I

Fig. 4 is a sectional elevation showing a modified form of the rest for supporting the guide.

Fig. 5 Fig. 1.

Figs. 6, 7 and 8 are end and side elevations of special cutting tools to be used in connection with my invention.

In the drawings like reference numerals indicate like parts.

In the drawings reference numeral 1 indicates the bed of a lathe having the head stock 2 and the tail stock 3. In the head stock is mounted to rotate the cone pulley 4 which drives a shaft 5 having a live center on the end thereof and a face plate 6.

On the tail stock is mounted the dead center 7 between which and the live center 5 the blank 8 is adapted to rotate. In front of the blank 8 is carried a pattern 9 supported on a rest 10 which in turn is supported from the shoe 11. The rest is supported on an upright 22 in which is a slot 12 through which passes a bolt 13 havlng a head 14 on the outer end thereof. This bolt passes through the upright 15 of the shoe. The outer end of it is threaded and is engaged by the hand wheel 16 by which it is clamped in place holding the upright of the rest between the head 14 and upright 15, and thus holding the rest in any desired position on the shoe. The uprights 15 and is a section on the line 5"5 of 22 are channeled so that the one nests into the other as is shown in section in Fig. 3. The base of the shoe has a slot 17 therein and the bed of the lathe has a slot 18 therein, extending transversely to the slot 17. Through these slots passes the bolt 19 by which the shoe may be clamped in any desired position, that is, it may be moved in or out or moved along the bed of the lathe and clamped as may be desired.

The rest 10 has an inclined bed 20 thereon on which the pattern 9 may be fastened by one or more screws 21. The top of the pattern is ordinarily placed below the top of the blank 8. This pattern is inclined upwardly toward the stock.

The working surface of the pattern is sawed out to the desired shape with a band saw and is then fastened on the rest. Tools such as are shown in Figs. 6, 7 and 8 are used. These tools have a cutting edge which corresponds to the outline of a short section of the pattern. The tool is laid snugly on the particular part of the pattern that it is intended to fit and the tool is then moved forward so that the cutting edge of it engages withand cuts the blank. The tool is advanced tangentially to the blank cutting its way through it and being held to the in clined position fixed by the pattern. When the tool has cut its way clear through the stock it will leave the blank cut to correspond with the shape of the pattern in that particular section.

Another tool is then used in connection with another section of the pattern and the blank is cut away by it in like manner. The depth to which the various tools cut the stock is indicated by the dotted circles and the lines tangential thereto, shown in connection with the blank 8 in Fig. 2. In addition to the special tools which are shown in outline in Figs. 6, 7 and 8 the ordinary cutting tools, such as are used in wood turning, may be used as well.

In Fig. 4 I have shown a modified form of a rest in which the shoe is indicated at 25 and is provided with a socket 26 in which is mounted a stem 27 of the rest 28, on which the pattern 29 is carried. Mounted in the shoe 25 is the threaded stud 30 on which is engaged the adjustment sleeve 31 which may be turned up and down thereon. This sleeve is shaped as shown in section in Fig. 5. On the top of the sleeve is a pin 32 which engages with the socket on the under side of the rest 28. By turning the sleeve 31 up so that the pin 32 engages the socket, the rear edge of the rest will be firmly supported. The stem 27 is clamped in place by the hand wheel 33 which has a threaded stem 34 thereon which engages with the threaded opening in the socket 26 which is used to clamp the stem 2-7 in any desired position. The stem 27 is released by turning the hand wheel 33 which then permits the raising or lowering of the rest. lhe adjusting sleeve 31 can be turned up or down to correspond with the position of the rest desired, after which the rest may be clamped in positionby the hand wheel 33. In this way the rest may be adjusted up or down to secure the proper elevation with relation to the blank 8, after which the blank 8 may be turned down by the use of the tools, as above described.

It will thus be seen, that when any desired round shapes are wanted a pattern can first be sawed in a block with a bandsaw after which the pattern may be fastened in the rest and the rest may be properly positioned with regard to the blank that is to be turned. in the lathe. The proper tools may then be laid upon the particular sections of the pattern as needed and moved straightforward and the tools being guided by the Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

pattern to make the proper cutting eflect both as to width and depth. After the various tools have been used in this manner the blank will be found to be cut or turned to conform to the pattern and a series of blanks may in like manner be turned from the same pattern, each of said blanks having the same side elevation as the pattern.

I claim.

1. The method of turning which consists in fashioning a pattern with a varying contour and with a transversely flattened surface of sufficient width to permit a tool to be steadily held and guided thereon without rocking motion; and supporting said pattern rigidly so that its flattened transverse surface is tangential to the finished work.

2. A pattern guide for controllinga hand operated wood turning tool comprising a transversely fiat surface of suificient width to enable the tool to be held steadily thereon without rocking and having longitudinally a varying contour and means for mounting and holding said pattern rigidly so that its fiat transverse surface shall lie in the plane of a secant to the blank or tangent to the finished work.

In testimony whereof I afiiX my signature in presence of two Witnesses.
