IMPROVED FEED-MOTION FOB DRILLS.
TO ALL WHOM IT MAY CONCERN Be it known that I, G. F. CASE, of the city and county of New York, have invented new and useful Improved Feed-Motion for Drills,.etc.; and I do hereby declare that the following .is a full, clear, and exact description thereofxwhich will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in whichi Figure 1 represents a longitudinal vertical section of this invention,
Figure 2 is a transverse section of the same, the line a: x, iig. 1, indicating the plane of section.
Similar letters of reference indicate like parts.
This invention relates to-an automatic feed-motion for drills, boring-bars, etc., and particularly for' what is known as Cases expanding drill for enlarging the diameter of oil wells. It consists of a feed-'screw provided with a nut and worm-wheel, to which a slow revolving motion is imparted by a worm, which revolves with the feed-screw, and which is caused to turn on its own airis by a suitable cam and corresponding cam-wheel, in such a manner that the screw is caused to advance slowly and continually, and a `uniform and automatic feed for the boring-bar or other mechanism is obtained. i
A represents the feed-screw of a boring-bar or of any other mechanism for boring` or other purposes. On this feed-screw is fitted a sleeve, B, so that said screw slides freely through the same in a longitudinal direction,
but a feather key, a, which catches in a groove in the screw, compels the sleeve to revolve with the screw.L
Said sleeve turns in a socket, b, in 'a suitable frame, G, and from it extends an arm, c, which supports two standards, al. These standards form the bearings for an arbor, e, on which is mounted the worm, f, and the cam-wheel, g. The wormf gears in a worm-wheel h, screwed `to a nut D, which screws on the feed-screw A, and which is confused between the sleeve B, and the cross-bar z', of the frame C, so that it is prevented from moving in a longitudinal direction, but entirely free to revolve. The cam-wheel g, meshes in a set of cams, j, which are rigidly attached tothe cross-bar z', and which are so shaped that each of them propels the cam-Wheel g, one tooth, so that when four cams are used, and cam-wheel has eight cogs,'for each revolution of the feedscrew the cam-wheel is caused to make half a turn round its own axis. It is obvious, however, that this proportion can be changed in many di'erent ways,.and I do not wish to confine myself to` any particular number and shape of the caros, neither to any particular number of cogs in the cam-wheel. As the cam-wheel, g, revolves, a slow rotary motion is imparted to the arbor e, and worm j, and this motion is'transmitted to the nut D, on the feed-screw, so that said feed-screw is caused to advance slowly but continually, and a uniform feed motion is obtained. It will be readily understood that this feed motion can be increased or diminished, by changing the shape of the cams j, the number of cogs in the cam-wheel, and also by increasing or diminishing the numberof cogs in the wormwheel, but if these parts are properly adjusted, a uniform and automatic feed motion is obtained, which is applicable to drills of any suitable description, and also `to devices for boring out cylinders, and to other similar mechanism.
What I claim as new, and desire to secure by Letters Patent, is-
The sleeve B, which carries the worm f, and cam-wheel g, in combination with the feed-screw A, nut D,
and worm-wheel all constructed and operating substantially as and for the purpose described.
