ATTORNEYS CHARLES COPELAND VERONEE, OF SUMMERVILLE, SOUTH CAROLINA.
LATHE ATTACHMENT.
To all whom it may concern Be it known that I, CHARLES C. VERoNEE, a-citizen of the United States, and a resident of Summerville, in the county of Dorchester and State of South Carolina, have invented a certain new and useful Improvement in Lathe Attachments, of which the following is a specification.
My invention relates to improvements in lathe attachments, and it consists in the combinations, constructions, and arrangements herein described and claimed.
An object of my invention is to provide an attachment which may be applied to a lathe of the ordinary construction, by means of which accurate tapers may be turned, or by means'of which curved surfaces, such as the ends of shells may be turned accurately.
A further object of my invention is to provide a device of the type described in which means is provided for adjusting the device so that curves of different radii may be cut, as well as tapers of different angles.
A further object of my invention is to provide a device of the type described which consists of relatively few parts, and which is therefore cheap to manufacture.
Other objects and advantages will ap pear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings forming part of this application, and in which-'- Figure 1 is a plan view of a portion of a lathe showing my invention applied thereto. Fig. 2 is a plan view of the device showing the attachment at work upon a taper. Fig. 3 is an enlarged section along the line 3-3 of Fig. 1. Fig. 4 is a section along the line 1-4 of Fig. 3. Fig. 5 is a side view of the radius bar and compound rest, the pivot bar being shown in section. Fig. 6 is an end view of the rest shown in Fig. 5.
Referring now to Fig. 1, I have shown therein certain parts which are common to ordinary lathes, such as the bed 1, chuck 2, the pulleys 3, the tail stock 4, and the carriage 5.
The parts just described are common and are to be found in all ordinary lathes. The attachment consists of movable members by means of which the lathe tool 6 is constrained to move in a given path, which path depends upon the purpose for which Specification of Letters Patent.
Patented Oct. 10, 1916.
Application filed April 4, 1916. Serial No. 88,889.
the work is intended, as for instance a taper or a curve, 'as in finishing a shell.
In the drawings I have shown a runway 7 whlch is designed to rest on the bed of the lathe, and which bears an adjustable slide 8, the latter being adjusted by means of a screw 9 which passes through a nut 10, see Figs. 1 and 2, by means of which the slide is forced forwardly or backwardly as desired. The slide 8 bears at one end a pivotally mounted support 11 whose pivot pin 12 extends through an opening13 in the slide. The support 11 is designed to hold the pivot carrier bar 14, this bar being secured inposition by means of a plate 15 and screws-16. At the tail stock end of the lathe there is a pivot carrier support composed of parts which are precisely like those described in connection with the members 7 to 16 inclusive, these parts being numbered 7 to 16 inclusive, with the exception of the member 14:, this member being held by the pivoted supports 11 and 11. I
Referring now to Fig. 5, I have shown therein a pivot carrier 17 which is secured to the bar 14 by means of the plate 18. The pivot is shown at 19, and to it is secured a member 20 through which an extension rod or radius rod 21 passes. A set screw 22 is for the purpose of clamping the rod 21 to the member 20. The opposite end of the rod 21 is connected at 23 to a slide 24., see Fig.
adjusted by means of a screw 27, the lower half 26 may be locked to the central slide 24 by means of a set screw 28, while bolts 29 lock the lower half 26 to the cross slide 30 of the lathe carriage.
From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Let us assume that a 10" shell is to be finished on a curve at its forward end. The shell 31 is placed in the chuck 2 and is held by the center pin 32 in the ordinary manner. The bolts 29 and the set screw 28 are released. The compound rest is free to slide to and fro and is also rotatable on the central pivot 35, see Fig. 6. The radius rod 21 is firmly clamped by means of the set screw 22, but it is free to swing about the pivot 19 as a center. The compound rest will cause the tool 36 to be moved in the arc of a circle, as the lathe carriage 5 moves forwardly. This insures the absolute accuracy of the work. Obviously the radius may be increased or diminished by shifting the radius rod 21,
- observed that the pivot carrier bar 1 1 is disposed at an angle to the axial line of the lathe center. This is done by loosening the plates 15 and 15, getting the proper adjustment by means of the screws 9 and 9, and afterwardsecuring these parts in position. The bar 21 is secured by means of a set screw 9 in any desired position, while the plate 18 is loosened to permit the movement of the-pivot carrier 17 along the bar 14. It will be obvious that, as such movement takes place, the tool 36 will come nearer the axial line. .In fact, it will substantially follow the line of the bar .14, or the axis of the same, so that a taper will be made on the piece 37 which is being worked. Obviouslythis taper may be varied as desired within limits.
1. The combination with a lathe provided with a'compound tool rest having relatively movable parts, of a bar, means for adjusting the position of the bar with respectto the axis of the lathe, a carrier mounted on said bar and slidable along the bar, a clamp for securing the carrier in its adjusted positions along the bar, said carrier having a pivoted portion provided with a slot arranged to extend therethrough, a radius rod having a portion extending through said slot, and means 'for securing the radius rod to said pivoted portion in adjusted positions with respect thereto, the opposite ends of the radius rod being secured to one of said movable portions of the compound tool rest.
2. The combination with a. lathe provided with a compound tool rest having relatively movable parts, of a bar, means carried by the lathe for adjusting the position of the bar with respect to the axis of the lathe, said means comprising a pair of slidable members carried by the bed of the lathe, pivoted supports carried at the end of said slide and adapted to receive the bar, screw shafts for adjusting the position of the slide, a car.- rier having a pivoted portion, said carrier being supported upon said bar, and slidable thereon, means for clamping the carrier rigidly to the bar at any position along the bar, and a radius rod connected with said pivoted portion at one end and with one of said movable parts of the compound tool at the other end.
3. The combination with a lathe provided with a compound tool rest having relatively movable parts, of a bar, means carried by the lathe for adjusting the position of the bar with respect to the axis of the lathe, said means comprising a pair of slidable members carried by the bed of the lathe, pivoted supports carried at the end of said slides and adapted to receive the bar, screw shafts for adjusting the position of the slide, a carrier having a pivoted portion, said carrier being supported upon said bar and movable thereon,means for clamping the carrier rigidly to the bar at any position along the bar, a radius rod connected with said pivoted portion at one end and with one of said movable parts of the compound tool at the other end, and a set screw carried by said carrier for holding the radius rod in adjusted position with respect to the carrier.
