Abstract: This invention relates to certain improvements in grinding or polishing machines, and relates more particularly to flat-surface grinders or what are generally known in the trade 1as "disk" grinders. An object of the invention is to provide certain improvements in bearings or mountings for the arbor of a flat or circular surface grinding-machine wherein the arbor carries one or more vertically or otherwise disposed grinding-surfaces, usually circular disks or chucks rigidly secured to both outer ends of the arbor and carrying the abrading or grinding surfaces, the work being- applied to the abrading-surfaces at the outer faces of said disks or chucks, a table or -other fixture or support being provided for each abrading disk or surface to hold the work. Claim: In combination, in a surface grinding-machine, a support, a rotary arbor mounted therein and having an end outwardly tapered with a reduced shouldered threaded extremity, a collar slipped on said tapered end, a key to hold the parts to rotate together and permitting removal of the collar, said collar having a reduced outwardly-extending hub around said extremity and having an end nut- 1 recess, a clamping-nut screwed on said threaded extremity and located in said recess, a grinding-head fitted on said hub and against the outer face of the collar, and means for removably clamping the head to the collar.

Manufactured by W. H. Fauber - Chicago IL
Assigned to Henry W. Norton - Wellington IL

The patent describes a one-piece crank shaft and related bearing structure for bicycles. Fauber's one-piece pedal crank was widely used in bicycles after its introduction. Early notices name "Fauber & Norton" as producers. An 1899 ad lists W.H. Fauber (Chicago) as manufacturer. In 1901, Fauber's company moved to Elgin, IL. The patent is referenced on combination hook and pin spanner wrenches designed to work with the bearings. Similar wrenches also reference a related sprocket wheel design patent (D31,194).

Manufactured by Gorton Machine Co. - Racine, Racine County WI

Abstract: his invention provides an improved cutter head assembly for routing and other rotary cutter spindle machine tools and the objects and nature of the invention will be understood by those skilled in the art in the light of the following explanations of the accompanying drawings that show what I now believe to be the preferred mechanical expression or embodiment of my invention from among other constructions, arrangements and combinations within the spirit and scope of my invention. An object of the invention is to provide an improved cutter head assembly for rotary Scutter spindles with the ends in view of increasing the accuracy of adjustments, the durability of operating parts and their accuracy in operation. Claim: A cutter head assembly embodying a supporting housing having a longitudinal guide slot; a barrel provided with and carrying a rotary cutter head spindle, said barrel longitudinally arranged and slidable in said housing and provided with a stop lug. rigid therewith and projecting outwardly through and beyond-said slot; a normally-fixed screw threaded shaft parallel with said slot and spaced outwardly therefrom; and an internally-threaded rotary sleeve on said shaft and meshing with the thread thereof and pro- 8 vided with a portion of- increased diameter forming an annular top stop abutment below and adapted- to abut the bottom edge of said lug to predetermine the cutting depth of the cutter carried by said spindle, a fixed longitudinal scale being provided along the path of movement of said enlarged diameter portion, said enlarged portion having a scale around the circumference thereof.

Manufactured by Gorton Machine Co. - Racine, Racine County WI

Abstract: An object of the invention is to improve rotary cutters of the single lip type for so-called engraving machines, die sinking machines, and the like, employed for engraving or cutting designs, indicia, letters, etc. in or on stamps, molds, dies, etc. as distinguished from the ordinary milling machine cutters which must comply with different conditions and requirements- than engraving machine cutters, with the ends in view of reducing the cost, of production, and of producing an engraving machine cutter to overcome certain defects in the engraving machine cutters now in general use, and of increased strength and durability, with a cutting or working end of increased length, "and capable of being more easily applied and removed. A further object of the invention is to produce a single lip rotary cutter for engraving machines, of improved shape and form, to overcome certain disadvantages and difficulties incidental to the form and construction of the engraving machine cutters now in common use, and to avoid the necessity of employing the objectionable pairs of opposite wrench faces on the exteriors of the central portions above the bases of the cutting ends of such old cutters. With the foregoing and other objects in View, my invention consists of a rotary cutter for engraving machines, of new and improved form and structure as more fully and particularly described and specified hereinafter.- Referring to the accompanying drawing, forming part hereof: Fig. 1 shows a form of my improved cutter in side elevation on an enlarged scale, looking at the flat of the cutting -end of the cutter. Claim: An engraving machine rotary cutter consisting of a conical shank of uninterrupted longitudinal taper from its base of maximum exterior diameter, and a single lip cutting end projecting longitudinally directly from said base, said cutter having a longitudinal fiat side throughout 125 the length of said cutting end and extended longitudinally of said tapered shank a substantial distance into and along said shank, said extended portion of said fiat side providing the wrench face of the cutter, whereby said cutter no0 is adapted to receive a complementary wrench to operatively fit said wrench face and the base portion of said shank and longitudinally and rotatively force said tapered shank into and from the engraving machine cutter spindle socket.
