RING-TURNING LATHE.
SPECIFICATION formingpart of Letters Patent No. 759,592, dated May 10, 1904. Application filed January 1i), 1904. Serial No. 189,226. (Nomodehl To all whom it may concern:
Be it known that I, WALTER CHRISTIE, a citience being had to the accompanying d rawings,
forming a part thereof.
My invention relates to improvements in ringturning lathes, and is particularly adapted for the purpose of turning, surfacing, or facing the circular tracks of gun-turrets.
In surfacing-or facing gun and turret tracks great difficulty has heretofore been experienced in holding the tool steady enough to obtain the accuracy desired. The diameter of these tracks is often very great, and extreme accuracy is absolutely necessary, especially in turret-work. My present lathe is designed with the object of obtaining, first, extreme rigidity of the main support; second, a large bearing for the revolving member upon such support; third, a form of tool holder or carrier which shall have a maximum rigidity, and, fourth, a machine that may be readily inverted, so as to make the angle of the upper or revolving turret-tracks exactly equal to the angle of the lower stationary track.
To these ends my invention consists in constructing the main support in the form of a drum-shaped turret having a circular guideway for the revoluble tool-carrying member, in providing a saddle rotatably fitted to the said guideway and provided with means whereby it may be rotated, and in constructing the tool holder or carrier of an arch-shaped beam secured to and carried by the saddle, said arch-shaped beam having an overhanging dependent end to which the tool-holder is socured.
My invention further consists in certain novel details of construction and combinations of parts, as will hereinafter be more fully pointed out.
I will now proceed to describe a ring-turning lathe embodying my invention and will then point out the novel features in claims.
In the drawings, Figure 1 is a View in cen' tral vertical section of a ring-turning lathe embodying my invention, showing the same in operation. Fig. 2 is an enlarged view in detail of the worm-wheel and gearing for revolving the beam. Fig 3 isa detail view of a thrust-bearing employed for the worm-wheel shaft. Fig. 4 is an enlarged View in side elevation, partially broken away in section, of a tool-holder employetfl. Fig. 5 is a view in transverse section of the same, taken upon the plane of the line 5 5 of Fig. 4. I
In the accompanying illustration I have shown the device as mounted over the turretpit 1 of a gun-turret and have provided beams 52 and supports 3 for supporting same. The lathe comprises a support 4, having the form of a hollow drum shaped turret provided with a circular guideway 5 and a saddle 6, rotatablylitted to said guideway. Secured to the saddle 6 is a worm-gear 7, with. which a worm-wheel 8 is arranged in mesh. The worm-wheel 8 is mounted upon a shaft 9, journaled in suitable bearings 10 and provided with thrust-bearings llvto take up the end thrust thereof. The worm-wheel 8 is driven through a train of gearing 12 from a driveshaft 13, upon which is mounted a belt-wheel let. A belt 15 engages the belt-wheel and a drive-wheel 16 upon an engine or motor 17 The saddle 6 supports an overhanging beam 18, the outer ends of which are facedofl at 19 in the plane of rotation of the said beam. A tool-holder 20 is fitted to one or both of the said surfaces, one of said tool-holders being shown in Fig. 1 of the drawings, it being understood that a similar tool-holder may be carried by the beam at its opposite end. The tool-holder 20, which is shown more fully in detail in Figs. 4c and 5, comprises a frame 21, provided with a guideway 22 for a tool-support, a tool-support 23, fitted to said guideway, and a feed-screw 24. has a screw-threaded engagement with a nut 25, carried by or constructed as a part of the tool-support, and is arranged in a line parallel with the plane of movement of the guideway 22. The feed-screw 24 is provided with an operating-head 26. Movement of the toolsupport 23 along the guideway 22 is in a plane at an angle to the surface 27 of the tool-holder, such surface 27 corresponding to The feed-screw the surface 19 of the beam to which it is fitted. Thus the tool carried by the said tool-support will have a feeding movement at an angle to the plane of rotation of the device.
In Fig. 1 of the drawings the tool is shown in engagement with a gun-turret track, (designated by the reference character 28,) the face of which is at an angle corresponding to the angle of movement of the tool. Thus it will be seen that by the use of my apparatus I am enabled to face off this track while in position. To face off the upper track of the revoluble gun-turret, it is only necessary for me to invert the tool, with the result that the angle of the track of said revoluble turret will be made to correctly correspond to the angle of the stationary track. It will of course be understood that while I am facing off the track of the revoluble turret I hold the same stationary by suitable means. (Not shown.)
What I claim is 1. In aring-turning lathe, the combination with a hollow drum-shaped turret having a circular guideway, of a saddle fitted to said guideway and supported to rotate thereon, an overhanging beam carried by the saddle, a tool-holder carried by the beam, and means for rotating the saddle.
2. In a ring-turning lathe, the combination with a hollow drum-shaped turret having a horizontal flange constituting acircular guideway, of a saddle fitted to said guideway and supported to rotate thereon, an overhanging beam carried by the saddle, a tool-holder carried by the beam, and means for rotating the saddle.
3. In a ring-turning lathe, the combination with a hollow drum-shaped turret having a circular guideway, of a saddle fitted to said guideway and supported to rotate thereon, an
overhanging beam carried by the saddle having a depending end, a tool-support carried by the said depending end, means for feeding the tool-support, and means for rotating the saddle.
4:. In a ring-turning lathe, the combination with a hollow drum-shaped turret having a circular guideway, of a saddle fitted to said guideway and supported to rotate thereon, an overhanging beam carried by the saddle, a tool-holder carried by the beam, said toolholder comprising atool-support, a guideway therefor arranged at an angle with respect to the plane of rotation of the beam and a feedscrew; and means for rotating the saddle.
5. In a ring-turning lathe, the combination with a hollow drum-shaped turret having a flange constituting a circular guideway, of a saddle fitted to said guideway and supported to rotate thereon, an annulus of U-shapd section secured to said saddle, and provided with gear-teeth, means, engaging said teeth, supported by said turret, for rotating the saddle, an overhanging beam carried by the saddle, and a tool-holder carried by the beam.
6. In a ring-turning lathe, the combination with a hollow drum-shaped turret having a circular guideway, of a saddle fitted to said guideway and supported to rotate thereon, an overhanging beam carried by the saddle, a tool-holder carried by the beam, and means located within and inclosed by said turret for rotating the saddle.
In witness whereof I have hereunto set my hand this 13th day of January, 1904.
WALTER CHRISTIE.
