Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed September 29, 1904. Serial No. 226,481.

To all whmn it may concern:

Be it known that I, JOHN BUFFELEN, a citizen of the United States of America, residing at Tacoma, in the county of Pierce and State of Washington, have invented certain new-- and useful Improvements in ,Woodworking- Maohines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to woodworkingmachines, and more particularly for those for turning wooden columns and other artioles having variable diameters, and has for its objects, first, to vary the diameter at different parts of the column Without shifting the knives; second, provide for tapering as well as bulging .in the column; third, finish the column from the rough in one action of the machine; fourth, to flute a finished column of irregular varying diameter without shifting the knife. I attain these objects by the devices illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my machine, being broken into three parts, so as to get it on the sheet. Fig. 2 is a plan thereof with the column removed, and Fig. 3 is an end view thereof. Fig. 4 is a side elevation of my knife, and Fig. 5 is a plan thereof. Fig. 6 is a detail showing the device connecting the feed-screw to the column-carriage, and Fig. 7 is a detail thereof. Fig. 8 represents the bent track on which the column-carriage travels. Fig. 9 is anend view of the groovecutter, and Fig 10 is a plan thereof. Fig. 11. is an end view of the column face-plate, and Fig. 12 is a side view thereof. Fig. 13 is a detail of the track-bending mechanism. Fig. 14 is a side view of the knife-spindles in their normal positions. Fig. 15 is an enlarged side View of the bearing-blocks for the knifespindles, and Fig. 16 is a plan thereof. Figs. 17, 18, 19, and 20 are exaggerated diagrammatic representations of some of the varia. tions obtained by altering the elevation of one of the face-plates and by bending the rail.

Similar numerals of reference refer to similar parts throughout the several views.

Above the rail-bars 3 are supported the rails 5 by the screw-supports. These screw-supports consist of the screw parts 6, screwing into a sleeve 7, supported on and secured to the rail-bar 3. One of each pair of the screwposts 6 isprovided with a hand-wheel 8, by means of which the screw-post is turned. The other screw-post of the pair is turned simultaneously by any suitable positive connection between the screw-posts. I have illustrated one such connection in Fig. 13. The bevel-gears 9 are secured to the screwposts 6'and gear with the bevel-gears 10, which are secured to the transmitting-rod 11, which is suitably supported on the blocks 12, secured to the rails 5 and into which the screw-posts 6 are journaled. Thus by turning the hand-wheel 8 of-- one of the posts 6 the corresponding post 6 is turned an equal amount, and the position of the rails 5 are simultaneously lowered or raised an equal distance, and as these screw posts 6 occur at frequent intervals the rails 5 may be bent to any form desired. I have-shown the rails 5 as being of double beveled shape, and this is the form I prefer, though there are many other forms which might be used.

The column-carriage passes along the machine on the rails 5 and is substantially a rectangular frame fitting around the column and composed of the two longitudinal members 13 slightly longer than the column and joined by the

end cross-pieces

14 and 15, which respectively form the head and tail of the carriage. Near each corner of the above frame the vertical screw-legs 16 pass, supporting the frame and being locked by the nuts 17. On the ends of these screw-legs 16 are pivoted the yokes 18, in which the beveled wheels 19, which run on the beveled rails 5, are journaled. The lugs 20 extend downward from the yokes 18 and pass under the edge of the rails 5, so as to hold the carriage down on the rails 5.

As the carriage is supported directly by the rails and as they can be bent so as to vary in height from the floor from point to point, it is evident that no inflexible connection can be made between the feed mechanism and the carriage. The feed-screw 21 is j ournaled to one of the rail-bars 3 and runs a little more than half the length of the rails 5. This feed-screw is driven by any suitable means, the pulleys 22 being shown to indicate that it may be run by belt from any counter shaft which is convenient. The feed-nut 23, which engages and travels along the feed-screw 21, slides along the rail-bar 3 and is provided with a long vertical extension 24, having the vertical slot 25 therein, in which the roller 26 is adapted to slide. This roller 26 is secured to a convenient point on one of the bars 13 of the column-carriage, so that as the screw 21 is turned it forces the carriage along the rails 5, the roller 26 passing up or down in the slot 25 with the variations in the height of the rails from the floor. The heights of the head and the tail cross-pieces 14 and 15 can be made to differ by means of the screw-legs 16, and as these cross-pieces directly carry the ends of the column it is evident that with a fixed vertical tool the column may be tapered from end to end.

On the head cross-piece 14 is mounted in suitable bearings the spindle 27, having secured to its outer end the bevel-gear 28, gearing with the bevel-pinion 29 mounted on the counter-spindle 30, which is also supported in suitable bearings on the cross-piece 14 and which has the grooved pulley 31 secured to its outer end. Thus by driving the pulley 31 the spindle 27 is rotated. On the inner end of the spindle 27 is secured the face-plate 32 which consists of a flat circular plate, into which the four bolts 33 are screwed, extending out beyond the face thereof, as shown in Fig. 12. On these bolts 33 are fastened the extension clutch plates or arms 34 by means of nuts, the bolts 33 passing through slots 35 therein. At a short distance from the end of each of the arms 34 are the pins 36, adapted to engage inside of the sections of the column, and directly across the ends of the arms 34 are the teeth 37, adapted to grip into the end of the column. The gage-marks 38 on the face of the plate 32 are made so that the arms 34 may be set symmetrically about the center and at the proper distance therefrom, enabling the pins 36 to engage the inner sides of the column-sections at the corners thereof and the teeth 37 to enter into the end of the column, and when the column is rotated on the spindle 27 it will be central therewith.

The tailpiece 15 has a sliding spindle 39, mounted in suitable bearings and having a face-plate 40, similar to the face-plate 32. The lever 41, which operates and controls the sliding spindle 39, has a ratchet-dog secured to its lower side to engage in the quadrantratchet 42, Fig. 2, so that when the faceplate 40 has been forced as far as it will go by means of the handle-lever 41 the ratchet and dog will hold it firmly in place.

The face-plate 32 is rotated, as above explained, by the grooved pulley 31. The grooved pulley 43, Fig. 1, is mounted in any suitable manner near the end of the machine and is driven by a belt from a counter-shaft through the pulleys 44. At the other end of the machine and in line with the pulley 43 is mounted the similar adjustable pulley 45. This pulley is mounted on the arm 46, which is supported by the two bolts 47 and 48. The bolt 47 is secured in the rail-bar 3 near its end and passes through the slot 49 in the arm 46, while the bolt 48 passes through the slot 50 in the post 4 and the slot 51 in the arm 46. Thus by loosening the bolts 47 and 48 the arm 46 and the pulley 45 may be moved into any desired position.

A small idle wheel 52 is mounted on the column-carriage at a point in line with and below the grooved pulley 31. An endless rope 53 passes around the above pulleys 43 and 45, around the idle wheel 52 and the pulley 31, so that when the pulley 43 is rotated it imparts rotary motion to the above parts, and thus to the face-plate 32, which turns the column supported betweenit and the face-plate 40. As the column-carriage is moved along the rails 5 by the feed-screw 21 the pulley 31 and the idle wheel 52 travel with it along the rope 53 and keep rotating, and, further, the rise and fall of the pulley 31 due to the abovedescribed bends in the track 5 will not affect its rotation on account of the flexibility of the rope.

The rough column is trimmed to the desired shape and diameter by means of the rotating knives suspended in fixed positions by the frame 54. I prefer to use three knives, which are secured into the

spindles

55, 56, and 57 These spindles are not quite vertical, but lean toward the head of the machine. In this way the knives are tilted, so as only to cut with the portion nearest the head, the other portion being elevated to clear the part already cut. The knife mounted on spindle 55 does the rough out, that one in spindle 56 cuts the column to size, while the one in spindle 57 smooths the column off. If it is desired to make afluted column, around column is first made as above. Then the knives in

spindles

55 and 56 are removed, the spindle 57 is made vertical by shifting the upper lower bearing 58 in the slotin the frame 54, the bearing 59 being adjustable in said frame, and a special knife is inserted in said spindle 57. The column is then held from rotating and the spindle 57 is elevated by means of a handle. The carriage is then fed. forward until the knife is at the point at which the flute is to begin. Then the knife is lowered and fastened, and the carriage is fed forward, thus cutting a flute in the column, the action being repeated for each flute. will be of uniform depth and shape because the knife is stationary, being fastened down, and the carriage will rise and fall for each flute on the bent track in exactly the same manner as it did when the smooth column. was turned before the fluting began. Three grooves are ordinarily turned. into columns of this character, one at each end, adapted to The flutes fit into the base and capital, and one near its upper end, into which a collar of molding is fitted. These .grooves I turn automatically at the same time that the column itself is being turned. This is done by mechanism illustrated principally in Figs. 9 and 10. T0 the part 13 of the column-carriage are adjustably secured the three knife-holder castings 60, being held in their proper positions fiat spring 67 is secured at its center to the Wise conical column.

center of the colunmcarriage. This spring 67 is slightly longer than the column-carriage and is bent away from the carriage except at the ends, which are reversed, so as to bend toward the carriage. This spring presses against the lug 65. The adjustable arm 68 is-secured to the machine at a point opposite the rotating knives and may be brought closer to or farther from the carriage, according to the depth of groove which it is desired to cut. As the carriage moves on the rails the arm 68 presses the spring 67 against the lug of the knife-bar 64, which in turn forces the bit 63 to cut the groove desired.

The spring 66 is compressed by this action;

but as the knife 63 passes the rotating knives the pressure is diminished and the spring 66 withdraws the knife 63 from the groove which it has cut.

In Figs. 4 and 5 I have shown the rotating knife 69, with which I turn the column. This knife consists of a central shank adapted to enter and to be fastened in a socket at the end of either of the spindles '55, 56, or 57, and of two knife-blades at the lower end of the shank.

Referring to the diagrammatic Figs. 17, 18, 19, and 20, I have intended to show therein in exaggerated form the possible adjustments of the carriage and track and the resulting shape of the column. Fig. 17 shows a straight track and the height of the head and tail pieces of the carriage equal, resulting in a perfect cylindrical column. Fig. 18 also shows a straight track, but shows the effect of raising the tailpiece above the level of the head-piece, this arrangement producing a perfect truncated cone-shaped column. Fig. 19 shows a half of the track straight, while the other half is sagged down, and also shows the tailpiece elevated, as in Fig. 18. This arrangement produces a bulge in the other- Fig. 20 also shows the tailpiece elevated, but shows a sag in each half of the track, producing still another shaped column. It is evident that by changing the point of sag and the amount of it and by adjusting the head and tail pieces of the carriage a large variation in the shape of the column may be attained.
