LATHE-SL1 DE-FEEDING DEVICE.
SPECIFICATION forming part of Letters Patent No. 274,394, dated March 20, 1883.
Application fil ed June 26, 1882. (No model.) 1
To all whom it may concern:
Be it known that I, ADOLPH W. ScHLEIcH- ER, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certain Improvements in Turning- Lathes, of which the following is a specifica tion.
My invention consists in the combination of an old mechanical device with certain mechanism described hereinafter, by which the said device is made available for feeding and regulating the feed of the carriage of a lathe and for reversing the same, asfnlly described hereinafter.
In the accompanying drawings, Figure l is a side view of sufficient of alathe to illustrate my invention, and Fig. 2 an end view of the same.
A represents part of the lathe-bed, and B the head-stock, to hearings in which is adapted the spindle D of the lathe. The outerend of the spindle is furnished with a bevel-wheel, a, which gears into a bevel-pinion, b, on the upper end of a shaft, E, the latter beingadapted to bearings 02 on a bracket, F, which is secured to the head-stock. On the lower end of the shaft E is a disk,f, the face of which is in contact with the periphery of a disk, 9, secured to the end of the spline-shaft G, which actuat'es the tool slide orcarriage and is adapted to hearings on the bed A, as usual. The pressure of the disk f upon the periphery of the disk 9 is regulated by the tension of a spring, m, interposed between the upper bearing, d, of the shaft E and a nut, 7%, adapted to a threaded portion of said shaft, so as to be adjustable thereon to vary the tension of the spring, the shaft E having a slight longitudinal play in its hearings.
It will be observed that the disk 9 is driven by contact with the face of the disk f, so that the speed at which said disk is driven and the direction of its movement will depend upon the relation to the center of the disk f of the point of contact between said disk'and the disk g-that is to say, the farther this point is from the center of the disk f the more rapid will be the rotation of the disk g-and when the point of contact between the disks is on the right-hand side of the center of the disk f the disk Q will be driven to the right, while when the point of contact between the disks is on the left-hand side of the center of the diskf the disk y will be driven to the left. The direction of movement and the speed of the spline-shaft G, and of the carriage controlled thereby, can thus be readii y governed by simply moving the disk glaterally across the face of the disk f, this movement being edected without any stoppage of the lathe. In the present instance I have shown as the means for eflecting this movement a lever, 12. having a pin adapted to the grooved hub of the disk g, the latterhaving a feather adapted to a keyseatin the shaft. Gr. Any other available means maybe used, however, in place of this arrangement, and the shaft E may, if desired, be acted upon by a weight instead of a spring to maintain the disk f in proper frictional contact with the periphery of the disk 9. The movement of the spline-shaft G being due to friction, any obstruction to the movement of the carriage will simply cause the disk f to slip upon the disk g, and will not be attended 'with injury to any of the parts of the device, as is the case when a positive feed is used.
A disk constructed to slide on but rotate withone shaft, and acting with its periphery on the face of another disk on another shaft, is an old device which has been used for feeding and changing the feed in machines. Hence I do not claim this, broadly; but
Iclaim as my invention-- The combination of a lathespindle, the feedshaft G, and the disk 9, constructed to he rotated with but to slide on. the said feed-shaft, with the shaft E, having a disk,f, and geared to the said lathe-spindle, and with aspring. m, for acting on the shaft, so as to force its disk against the periphery of that on the feed-shaft, all substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
