To al?, whom it puny cm1/cern:

Be it known that I, ALPHONSE DE FONTAINE, director, a subject of the King of Prussia and Emperor of Germany, residing at Dr. Otto- 5 strasse 119, Dahlhausen-on-the-Ruhr, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in Apparatus for Rolling Disk fheels or Similar Articles, of which the following is IO a full, clear, and exact description.

The apparatus forming the subject of the present invention and which is for rolling disk wheels and similar articles is intended exclusively for use in rolling-mills in which the I5 work is to be treated by means of conicallyshaped rollers. A treatment of this kind has heretofore only been effected as a so-called finishing operation, because the blocks to be treated have always had to be forged as a preliminary operation, as the conical rollers served only to give the final shape to the work.

Now the apparatus forming the subject of the present invention is designed to effect the complete rolling out of the disk, so that the preparatory forging ofthe blocks becomes superiiuous. Rolling-mills of this kind have always been constructed heretofore in such a manner that the conical rollers were mounted on shafts arranged at an angle to each other,

so that the work which was already forged to the shape of a disk was fixed between the said rolls either vertically or horizontally, accordingto the position of the rolls. Apart from the fact that the construction of such rolling-mills was Very complicated in consequence of the angular position of the axes of the rolls it was necessary in order to enable accurate work to be produced to arrange one roller (generally the so-called f pressureroller,7 operated by hydraulic pressure) in an adjustable manner in its axial direction, so thatthe said roller should always be at the same height as the so-called driving-roller during the rolling operation. Now according to theimprovement hereinafter described the adjustability of the so called pressureroller is rendered superfluous and also the angular arrangement of the axes of the rolls is entirely avoided. rThe consequence of this arrangement is that any rolling-mill frame, and especially the frame of the twyer rollingmill, which is to be found as a necessary constituent of the entire rolling-mill, can be utilized. This isamost important point, because such rolling-mill frames are to be found in every large works. The improvement is substantially characterized by the fact that the so-called driving-1olle1"is mounted horizontally on the driving-spindle, (which is arranged vertically in the usual rolling-mills,) while the ,so-called pressing-roll is mounted obliquely upon the table which moves at right angles to the driving-spindle. With this arrangement of rolls the Work is fixed, not horizontally or vertically, but obliquely-M that is to say, so as to be capable of vertical adjustment parallel to the sides of the rolls which operate upon it--the said work being carried by a supporting-spindle, which is arranged at right angles to opposite generatrixes of the surfaces of the rolls and which is capable of being adjusted in its distance from the rolls. This last circumstance has two advantages: First, disks of different sizes can be rolled by means of one and the same pair of rollers, according to the vertical position of the supporting-spindle, and, second, by altering the position of the supporting-spindle as to height during the operation the adjustability of the pressing-roller in its axial direction, which would otherwise be necessary,

is obviated. In order to be able to roll the rim of the disk at the same time as the latter is being rolled out, a further suitably-shaped roller is provided on the frame of the rollingmill, and it is supported in an adjustable manner.

trate my improvements, Figure 1 isa side elevation` partly in section, showing the rollingmill. Fig. 2 is a plan, and Fig. 3 is a cross-section thereof.

' The frame of the rolling-mill is similar to that which is suitably employed for rolling tires. It consists, substantially, of the frame r, which serves to support the vertical driving-shaft p and also the hydraulically-operated carriage s with the piston 7c and the cylinder e. Upon the vertically-arranged driving-shaft p there is mounted in a horizontal manner the conically-shaped roller a, which is mounted on its shaft in the simplest manner, preferably by keying. The so called pressing-roll b is mounted, on the contrary, obliquely on the carriage s, for which purpose there is employed a conically-shaped pin or journal c, upon the uppery stepped end c of which the roll b is mounted in a rotary manner, while the pin is fixed by means of its square parts 02 03 to the carriage s or to a bracket t, bolted thereto.

The carriage s is moved in the frame 1' by means of the piston 7c by hydraulic power forward in the usual way, while the return movement of the carriage is effected by means of hydraulic power acting upon a piston o, that is guided in a cylinder y, preferably arranged below the cylinder e, by means of the pistonrod u, which is connected to the bracket t, or steam-power may be used for this purpose. The block to form the disk gis fixed between the opposite or facing sides of the two rollers a and at an inclination to the horizontal sides of the rollers and so as to be adjustable as to height parallel to the sides of the said rollers. This is effected by mounting the block on a vsupporting-spindle L, which is arranged at right angles to the opposite generatrixes of the surfaces of the rolls and which is guided adjustably as to height parallel in its distance from the rolls by means of its square part /L in the bearing-frame t'. The bearing-frame t' is preferably made to embrace roll a, so that the latter is contained almost completely in the bearing-frame, and it can be provided with any suitable adjusting device for adjusting the part h' of the supporting-spindle L during the working. This is effected, as above mentioned, in order to avoid the formation of steps in rolling out the disks, which could otherwise only be effected by mounting the pressingrolls in an adjustable manner. For the purpose' of forming the rim g/ there must be provided a further and specially-formed roll f, the bearing m of which is mounted adjustabl y in guides n on the frame, so that the roll f is adjustable parallel in its distance from the work. It will be advisable for the purpose of enabling the bearing to be shifted during the working to connect it with the spindle B (which is also arranged in the block A in such rolling-mill frames) by means of the'carriage D and the press-rod E, so that by rotating the spindle Bin the ordinary manner the roll f can be adjusted to the correct position for the purpose of forming the rim of the disk.

It will be noted that in the specific construction and arrangement as embodied in my invention and improvements the apparatus comprises, in association with a verticallyarranged driving spindle, a horizontallymovable carriage and conically-shaped rolls mounted, respectively, on the driving-spindle and obliquely on the movable carriage, that the supporting-spindle which is adapted to carry the work is adjustable parallel to itself in the plane of the geometrical axes of the rolls and in the direction of the line which constitutes the bisector of the angle formed by the aXes of the rolls, and that the roll for lforming the rim is adjustable parallel in its distance from the work.

I/Vhat I claim, and desire to secure by Letters Patent, is-

l. In an apparatus for rolling disk wheels and similar articles embodying a verticallyarranged driving-spindle, a horizontally-movable carriage and conically-shaped rolls mounted respectively on the driving-spindle and obliquely on the movable carriage, a supportingspindle adapted to carry the work and adjust'- able parallel to itself in the plane of the geometrical axes of the rolls and in the `direction of thc line which constitutes the bisector of the angle formed by the axes of the rolls.

2. In an apparatus for rolling disk wheels and similar articles embodying a verticallyarranged driving-spindle, a horizontally-movable carriage and conically-shaped rolls mounted respectively on the driving-spindle and obliquely on the movable carriage, a supportingspindle adapted to carry the work and adjustable parallel to itself in the plane of thegeometrical axes of the rolls and in the direction of the line which constitutes the bisector of the angle formed by the axes of the rolls, and a roll in the plane of the work and adjustable in such plane in its distance from the work for forming the rim.

In witness whereof I subscribe my signature in presence of two witnesses.
