ADJUSTING MECHANISM FOR UNIVERSAL MILLS.
SPECIFICATION forming part of Letters Patent No. 657,823, dated September 11, 1900.
Application filed April 26, 1900. Serial No. 14,471. (No model.)
To all whmn it may concern:
Be it known that 1, CHARLES L. HUSTON, a citizen of the United States, and a resident of Ooatesville, Pennsylvania, have inventedcertain Improvements in Adjusting Mechanism for Universal Mills, of which the following is a specification.
The object of my invention is to improve the construction of the adjusting mechanism for the vertical rolls of a universal rollingmill, whereby lost motion can be taken up, as fully described hereinafter.
Referring to the accompanying drawings, Figure 1 is a side view of sufficient of a universal rolling-mill to illustrate my invention. Fig. 2 is a front view showing one-half in section on the line 2 2, Fig. 1. Figs. 3 and lare detail views illustrating my invention, and Figs. 5 and o are views of constructions I may use in carrying out my invention.
A indicates the housings, and in these hous ings are the horizontal rolls B B, of the ordinary type.
D indicates the vertical rolls. In the present instance there are two sets of these rolls, one set mounted on one side of the horizontal rolls and the other set on the opposite side. The rolls D D are mounted in suitable bearings d d in guides A A and the bearings of each set are connected together by a frame D. The lower end of each roll D is mounted in a stepbearing cl on a guide-bar A E is the driving-shaft for the vertical rolls, and splined on the driving-shaft are bevelgears e,which will freely slide on but turn with the shaft. On the upper end of each vertical roll D is a bevel gear-wheel cl, which meshes with the bevel-wheel e. The wheel e is retained in gear with the wheel (I bya projection e on the frame D, which enters an annular groove in the wheel 6, so that the wheel 6 moves on its shaft when the frame D is adjusted.
In order to move the vertical rolls toward and from each other, adjusting-screws F F are provided. In the present instance the screw F projects from the rear of the frame D on aline with the bearing d and the screw F projects from the rear of the frame D in line with the bearing d In each of the'housings A are screw-threaded bushings or fixed nuts G, having threads which mesh with the threads of the screw, so that as the screws F F are turned the frames D, which are coupled to the heads fof the screws, will be moved toward or from each other.
On the screw F is a gear-wheel h, and on the screw F is a gear-Wheel 71. These gearwheels are splined to the screws, so that the screws can slide through the gear-wheels, but must turn with them.
H is a power-driven shaft extending from one housing to the other, and on this shaft are two gear-wheels h One of these gearwheels meshes with one gear-wheel it on one side of the mill and the other with the other gear-wheel h on the opposite side of the mill, so that when the power-shaft is turned motion will be imparted to both gear-wheels and to their screws. On eachside of the machine is an intermediate gear-wheel t, which meshes with the gear-wheel h and with the gearwheel h, s0 that motion is imparted from the upper wheel h to the lower gear-wheel h through this gear-wheel t', and thus the screws F F on each side of the .mill are moved simultaneously. In order to keep the gears in proper alinement, two frames 0 O are used, one on each side of the train of gears, and the hubs of the gear-wheels h h are extended and have their bearings in these frames. The
frame O is also supported by a hollow stud J, which is attached to the housing A and projects a sufficient distance to carry the intermediate gear-wheel 't'. The hub of this gear-wheel i is extended at one side and finds its bearing in the outer frame 0, as clearly shown. The object of this construction is to enable the flanged nut z" to be secured to the hub of the gear-wheel In the present instance the hub of the gear-wheel has a circular T-headed slot f, in which the heads of the bolts are confined. These bolts are for the purpose of rigidly attaching the nut t" to the gear-w heel t'. Passing through the hollow stud and through the nut 2" is a screw I. The inner end of this screw is attached to the frame D. The screw passes freely through the hollow stud; but the threads of the nut mesh with the threads on the screw. Thus it will be seen that when it is wished to adjust the vertical rolls toward or from each other the driving-shaft H is set in motion and lOO wheel by tap-bolts.
ceases the gear-wheels h h on each side of the rolls will turn their screws F F, so as to feed the frame and its vertical rolls forward, for instance, while the nut t" on the gear-wheel i will turn on its screw I, so as to allow the screw to move forward with the frame. In case of lost motion, however, the nut i can be detached from the gear-wheel and the outside frame '0 can be moved out sufficiently to allow for the withdrawal of the gear-wheel 2', which canthen be turned a tooth or two, as desired, and placed back in position, so that when the parts are again in gear the lost motion will be taken up. In some instances when the construction shown in Fig. 2 is used I need only loosen the bolts 70 and turn the nut on the screw and tighten up the bolts as desired; but where it is desired to positively secure the nut to the gear-wheel I prefer to use the construction shown in Fig. 5, which simply shows the nut rigidly secured to the Fig. 6 shows another form in which the wheel 11 is keyed to the nut, the key being loose in one part, so that on removing the collar Z and the outer frame 0 the wheel 2' can be moved out, so that the teeth of the wheel will clear the teeth of the wheels h h, when it and its nut can be turned one or two teeth, as desired, and replaced in position. It will thus be seen that by my invention I can readily take up any slack that occurs in the adjusting mechanism of the vertical rolls of a universal mill.
I claim as my invention- 1. The combination in a universal mill, of the vertical rolls, a supporting-frame therefor, adjusting-screws attached to said supporting-frame, a gear-wheel keyed to each screw,an intermediate gear-wheeland a screw name to this specification in the presence of attached to the frame, the thread of said screw meshing with a screw-thread in said intermediate gear-wheel, the screw being moved laterally thereby without being rotated, substantially as described.
2. The combination in a universal mill, of the vertical rolls, supporting-frame therefor,
adjusting-screws extending from the frame, a gear-wheel on each screw, an intermediate gear-wheel, a screw projecting from the frame and extending through a bushing on which said gear-wheel operates, and a nut on the screw connected to the intermediate gearwheel, substantially as described.
3. The combination in a universal mill, of the vertical roll,'bearings therefor, a frame carrying the bearings, a housing, nuts therein,screws meshing with the nuts, gear-wheels on the screws, an intermediate gear-wheel, a hollow stud projecting from the housing and carrying the intermediate gear-wheel, a screw attached to the frame passing through the hollow stud, a nut on the screw, said nut being detachably secured to the hub of the intermediate gear-wheel, substantially as described.
4, The combination of the housings ofa universal mill, vertical rolls, bearings therefor, a frame carrying the bearings, housings, screw-threaded bushings therein, a screw passingthrough each bushing and attached to the frame, a gear-wheel splined to each screw so as to turn the screw in its bushing, a hollow stud projecting from the housing midway between the two screws, an inter- -mediate gear-wheel carried by the hollow stud, frames on each side of the train of gears, a screw passing through the hollow stud and attached to the supporting-frame of the vertical rolls, said screw being right-handed and movable laterally through said hollow bushing, a flanged nut on the said screw, and
.bolts securing the nut to the hub of the intermediate gear wheel, substantially as described.
In testimony whereof I have signed my two subscribing witnesses.
CHARLES L. HUSTON.
