ROLLING-MACHINE FOR TAPERING BARS.
SPECIFICATION forming part of Letters Patent No. seeevi, dated august 23, les?. Application filed May 12, 188'?. Serial No. 237,977. (No model.)
To @ZZ wwm it may concern:
Be it known that I, GEORGE M. HUeHEs, of Wagon W'orks, iu the county of Lucas and State of Ohio, have invented new and useful Improvements in Machines for Rolling Axle- Spindles and other Tubes; and Ido hereby dcclare that thefollowing is a full, clear,V and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.
rIhis invention relates to new and useful improvements in machines for rolling the spindles of carriage and wagon axles and other tubes; and the invention consists in the improved construction, arrangement, and combination of parts, all as more fully hereinafter described.
In the drawings which accompany this specification, Figure lis a side elevation of my improved machine. Fig. 2isaplan thereof. Fig. 3 is a side elevation of the carriage with the supporting-frame shown in crossscction. Fig. 4 is a cross-section on the line :c .fr in Fig. 2. Fig. 5 is a section on line y y in Fig. 4. Fig. 6 is a plan of one of the Vradially-adjustable boxes in which the taper-rolls are journaled. Figs. 7 and S are perspective details of these boxes, as indicated by the letters of reference.
A is the supporting-frameof the machine. B is a shaft journaled in suitable bearings, C. D is a drivepulley on the shaft B; and E are taper-rolls journaled in bearings in the disks c a', which are secured to each other and to the shaft B, so as to form a single revolving head in which the taper-rolls are free to turn on their axis. The disks aa are firmly secured together the necessary distance apart by means of stay-bolts b. The disk a is secured by means o'fa hub on the'end of the shaft B, and the disk to has a central aperture. The two disks a a' have corresponding radial slots c, in which the boxes for the taper-rolls are secured radially adjustable.
There are preferably three taper-rolls placed at equal distances apart and at the same radial distance from the axis of the disks a a', and the boxes cl, in which these taper-rolls are journaled, are what is termed rocking boxes,7 so that the rolls may be adjusted radially in or `out independently at either end so as to change their inclination toward the common axis.
'Ihe specific means which I have devised for the radial adjustment of these rolls are as follows: The boxes d, in which the rolls are journaled,are provided with trunnions e, and these engage into eyes f, formed in the lower ends of radially-adjustable stirrups g,one of which is shown det-ached in Fig. 8. VThese stirrups engage with the parallel sides of the radial slots c in the disks and terminate at their upper ends in threaded bolts h, which pass through caps t', secured over the peripheral openings of the slots, and are adjustably suspended therefrom by nuts 7c. A screw-bolt, Z, is threaded through the center of each cap and bears against the top of the box, which is provided at this place with a circular bearing, ml, which has its center of radius in the axial center of the box.
By means of the construction described it will be seen that each box is free to rock and can be adjusted radially in or out. As it is, however, required to have the boxes in each disk adjusted alike, Iprovide each disk with a ring, n, which has eccentric slots o, into which each stirrup engages by means of a suitable lug, 19, all so arranged that by turning the ring all the stirrups are radially adj usted in or out alike. After the adjustment cach box is then firmly secured by its own adjusting devices.
G is a two-part clamp, preferably formed by two sliding clampjaws, which carry V-shaped steel blocks, the common center of which is in exact line Vwith the axis of the shaft B, and which are provided with a right and left hand screw, H, for operating them, and are mounted on a carriage, I, which slides on ways on the frame A. The latter forms an integral portion of the frame A, but makes a rearward ofi'- set therewith, as shown, whereby a closer approach is provided to the carriage.
lIhe carriage is provided with suitable means-such as a rack and pinionand with a large hand-wheel, J, to apply manual power to approach and -retract the carriage toward and from the rolls.
An adjustable stop, K, is provided to stop the advance of the carriage at a desired point.
In practice the machine is devised and applicable for rolling the spindles of so-eallcd tubular axles77 and other taper-tubes, and the mode of operating is as follows: The blank,
IOO
being properly heated at one end, is clamped between the jaws with the heated end toward the rollers, and with a collar, m', previously secured thereon, in contact against the jaws, as shown. Motion being given to the shaft B, the operator, by means of the hand-wheel J gradually advances the carriage and forces the heated end of the blank into the central space between the rolls, thereby compressing it into the desired shape.
The rolls in being revolved around the common center are free to rotate on their own axis; but they remain in xed relation to each other 'during the entire process of rolling, and the machine therefore differs in its construction and operation from other machines of a similar character wherein rolls are employed which impart the desired shape and size by closing down upon the work with a radial movement; and it is obvious that my machine is not alone of a much more simple character, but is capable of superior work in connection with tubular axles and other taper-tubes, as it produces no longitudinal displacement and is susceptible of very accurate adjustment for any and all sizes and shapes of spindles or ends.
It is obvious that the head which carries the taper-rolls may be also supported at the outer end by means of a hollow bearing which permits the introduction of the blank. Such bearing, however, I preferably dispense with by a suitable mechanical construction of the other parts, as I am enabled thereby to shorten the movement of the carriage and enable the operator to perform his work to better advan tage.
What I claim as my invention isl. In a machine for the purpose described, the combination of a revolvinghead provided with a series of three or more taper-rolls grouped in adjustable bearings around the center of motion, and a carriage provided With a clamping device and means for advancing and retractingit toward and from the revolving head, all constructed and arranged substantially as and for the purpose described.
2. In a machine for the purpose described, the combination, with the frame A, carrying the taper-rolls E, of the frame A', forming the offset described'with the frame A and supporting the carriage I, all substantially as and for the purpose set forth.
3. In a machine for the purpose described, the combination, with the supporting-frame, of the shaft B, journaled in suitable bearings thereon, the revolving head secured to said shaft and consisting of the disks aa and staybolts b, the taper-rolls E, journaled in radially-adjustable boxes in the disks a a and grouped around the center of motion of the revolving head, and the carriage I, having the clamp-jaws M, the clampscrew H, and the hand-wheel J, all arranged to operate substantially as set forth.
4. In combination with the rolls E, the radially-slotted disk a, the boxes d, having trunnions e and circular bearing m, the stirrups d, having eye f and screw-bolt h, the screwbolts Z, and the caps z', all arranged to operate substantially as described.
5. In combination with the taperArolls E, the radially-slotted disk a, the boxes d, the stirrups g, radially adjustable within the slots of the disks and carrying the boxes d, and the ring n, having eccentric slots engaging with the lugs p on the stirrups, all arranged to operate substantially as described.
6. In combination with the taper-rolls E, the radially-slotted disks a a andthe boxes d, supported on trunnions .within said slots, and means for radial adjustment, substantially as and for the purpose described.
7. In a machine for the purpose described, in combination with the frame A A', having the offset described, theshaft B, supported in standards C and having drive-pulley D, the three rolls E, journaled in radiallyadjustable rocking boxes in a revolving head secured to said shaft, means for radially adjusting all the boxes at one end of the rolls jointly with each other, but independently from the boxes at the other end of the rolls, a carriage having a clamping device to hold the blank in the center of motion of the rolls, and means for operating the carriage to introduce the blank endwise between the rolls, substantially as described.
