DEVICE FOB. DRESSING CASTINGS AND THE LIKE.
Application led December 26. 1913.
To all whom t may concern Be it known that I, THEoDoR STIEGEL- MEYER, a citizen of the German Empire, and residing at IIanover- Wlfel, Germany, have invented a certain new and useful Improved Device for Dressing Castings and the like, of which the following is a specification.
My invention relates to devices for dress ing, c'. e. skimming, hammering or otherwise working up the surfaces of castings, metal plate or sheets, rivet heads and the like, and relates particularly to devices of that class wherein the dressing tools pass through and are radially displaceable in slots in the peripheral wall of a rotating hub or roller, the
said tools being pressed outwardly by centrifugal force but being able to yield radially when coming in contact with the surface to be worked.
A primary object of my invention is to obviate those defects in known devices of said class which, as will be later explained, result from the limited play allowed the tools and which are liable to lead to breakage of the latter. To this end, I so construct my'device that the tools or tool-actuating members which are subjected to centrifuga-l action are displaceable not only radially in the direction of the centrifugal force but are also capable of a substantial displacement laterally of said direction, and are preferably displaceable within a circular range of movement. The consequence is that if one of the tools comes against an elevation on the surface to be worked, the said tool can yield both radially and also in the circumferential and axial direction of the driving hub. The action of the working tool on the surface operated upon is thereby very much improved and a regular, smooth surface of the work before being dressed is no longer essential.
Figure 1 is a transverse section of one form of my device for dressing the surface of castings, metal plates and the like, and Fig. 2 a longitudinal section of the same; Fig. 3 is a transverse section of a somewhat modified device for the same purpose, and Fig. 4 a longitudinal section of the same.
Referring to the drawings, the device shown in Figs. l and 2 comprises a roller or hub a which is rapidly rotated and in the periphery of which are slots or holes b having conical edges c which diverge outwardly. Through these holes pass pins or tools d Specification of Letters Patent.

having heads f which abut against asleeve e. INhen the hub a is rapidly rotated, the tools Z fly outwardly under the action of centrifugal force. vWhen they strike the surface to be dressed or a high place or elevation on this surface, they can, while delivering a blow on the said surface or high place, yield radially inward.` Further, owing to the conicityof the holes Z; the said tools are displaceable within a circular range of movement, so that they can yield both axially of, and in the circumferential direction of, the hub a. It is thereby possible to use the tool for dressing surfaces having elevations of any kind. This was not possible when the working members, while being subjected to centrifugal action, were only radially displaceable, because in that case they would catch against high places on the said surface and so be liable to breakage.
The embodiment shown in Figs. 3 and 4 differs from that shown in Figs. l and 2 in that the tools d have a larger range of movement. As is evident from Fig. 3, instead of the conical holes b in the outer wall of the hub a, slots g are now formed in said wall, which have a longitudinal axis in the circumferential direction of thehub a. The outer edges of these slots are in this case also beveled off. The tools Z which pass through these slots can also obtain not only a radial displacement and a displacement within a circular range ofV movement but also a further displacement circumferentially of the hub a. It is thereby obtained that surfaces having very high ribs or ridges can be dressed without danger of breakage of or damage to the tools.
The operation of this device may be effected in various ways. In Figs. 2 and 4 the projecting end it of the outer member a is provided with a gear z' which may be driven from any suitable source not shown.
I claim 1. In means for dressing castings, plates, rivet heads, and the like the combination of a rotatable member having a plurality of conical openings with a plurality of strikers disposed within said conical openings and being vadapted to move radially withrespect to the axis of rotation and to move circularly in every direction.
2. In means for dressing castings, plates, rivet heads, and the like the combination of a rotatable member having a plurality of openings, said openings having beveled outer edges, a plurality of tools'located in said member and having thickened inner ends Y Withinv the member and being adapted to move radially With respect tothe axis of rotation and to move circularly in every direction.
. 3. In means for dressing castings, plates, rivet heads and the like, the combination of a rotatable member having a plurality of conical openings, a plurality'oi:I strikers disposed vWithin said conical openings and means for forming an inner abutment Jfor said strikers, said strikers being adapted to move radially with respect to the axis of rotation and to move circularly in every directIOIl'. Y
4. In means for dressing castings, plates,
Vrivet heads and the like, the combination of a 'rotatable member having a plurality of conical openings With a plurality of strikers disposed WithinA said conical openings, a
sleeve mounted coaXially with said rotatable member and forming an inner abutment for Copies of this patent may be( obtained for said strikers, said strikers being adapted to move radially with respect to the axis of rotation and to move circularly in every direction.
