"Vintage Machinery" entry for C. L. Hawes
Description:
Abstract:

The object of the presently invention is to provide a polishing or grinding machine of the dual opposed wheel type, which will be capable of automatically operating on articles such as axes, hatchets, and 'the like. For operation on articles of this character, the grinding or polishing wheels require, to be more or less closely positioned as different portions of the article are presented. Means on the order of a template are accordingly provided, whereby the position of the two wheels is simultaneously automatically controlled so as to cause them to grind in the desired plane or planes, and thus conform with the surface of the article being finished. In the case of an ax or hatchet, the two surfaces of the article are symmetrical, and the adjustment of the two wheels accordingly is in unison but in opposite direction. This, however, ,need not necessarily be the case, and furthermore, by an adaptation, articles of circular cross-section, such as certain forms of hammerheads, for example, which constitute frustra of cones or pyramids, may be ground with equal facility.

5. In a machine of the character described, the combination with. a suitable base; of two spindles mounted so as to be movable in unison towards and from each other and respectively provided with a polishing or grinding wheel; a pivoted work-holding member bodily movable in fixed plane between said spindles both parallel with` and transversely of the axes of said spindles; and means adapted to move said member in each such direction independently of the other, and conjointly connected to and supporting said member.

6. In a machine of the character described, the combination with a suitable base; of two spindles mounted so as to be movable in unison towards and from each other and respectively provided with a polishing or grinding wheel;` a pivoted work-holding member bodily movable in fixed porting said member.

7. In a machine of the character described, the combination with a suitable base; of two spindles mounted so as to be movable in unison towards and from each other and respectively provided with a polishing or grinding wheel; a member disposed parallel with said spindles and adapted to support the article to be operated on between said wheels; cranks pivotal about axes transversely of said spindles; and links connecting said cranks with said member, whereby the latter is moveable both up and down and longitudinally.

8; In a machine of the character described, the combination with a suitable base; of two spindles mounted so as to be movable in unison towards and from each other and respectively provided with polishing or grinding-wheel; a member disposed parallel with said spindles and adapted to support the article to be operated on between said wheels; interconnected bell-cranks pivotal about axes transversely of said spindles; links connecting said bell-cranks with said member, whereby the latter is movable both up and down and longitudinally; and means adapted to rock said bell-cranks.

9. In a machine of the character described, the combination with a suitable base; of two spindles mounted so as to be movable in unison towards and from each other and respectively provided with a polishing or grinding wheel; a member disposed parallel with said spindles and adapted to support the article to be operated on between said wheels; interconnected bell-cranks pivotal about axes transversely of said spindles; links connecting said bell-cranks with `said member; means adapted to rock said bell-cranks whereby said member is moved up and down; and other means connected with said member to move the same longitudinally.

10. In a machine of the character described, the combination with a suitable base; of two spindles mounted so as to be movable in unison towards and from each other and respectively provided with a polishing or grinding wheel; a member disposed parallel with said spindles and adapted to support the article to be operated on between said wheels; interconnected bell-cranks pivotal about axes transversely of said spindles; links connecting said bell cranks with said member; means adapted to rock said bell-cranks whereby said member is moved up and down; and other means connected with said member to move the same longitudinally, said last named means operating more frequently than those first-named.
