The pintle 41 has an extension 46 cincinntai which is mounted an eccentrically adjustable pulley 47, and in order to adequately support the pulley an additional pillow block 48 is provided for supporting the free end of the extension Since the whole weight of the grinding wheel and part of its driving mechanism is supported on the threaded connection in the extensible link, thereby creating a large amount of friction, when adjustments are necessary and since the eccentric shaft must lift the entire weight of the grinding wheel during grinding operations, means are provided for counter-balancing all of the weight of the grinding wheel so as to provide a definite bias on the grinding wheel support structure in an upward direction, thereby necessitating a slight pull by the operator to move the grinding wheel down during the grinding operation.
Other objects and advantages of the present invention should be readily apparent by reference to the following specification, considered in conjunction with the accompanying drawings forming a part thereof and it is to be understood that manal modifications may be made grinddr the exact structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.
The grinding wheel is so positioned and supported by its bracket that a line passing through the centers of the grinding and the regulating wheel during the grinding operation is substantially parallel to the guideway for the regulating wheel so that any adjustment of the regulating manuual slide toward and from the grinding wheel will be more accurately indicated by the graduations on the adjusting screw for the regulating wheel housing.
This invention aims to provide a small compact and simplified centerless grinding machine of such a nature that it may be mounted on a bench or table, or as shown in Figure 1 of the drawings upon a pedestal specially provided for the purpose. In a centerless grinding machine having a grinding wheel and a regulating wheel supported in opposition to form a grinding throat therebetween, the combination of an oscillatable work carrier having means for moving work into and out of the grinding throat in a direction lateral of the axis thereof, said carrier having a work rest blade mounted thereon for movement therewith, means for infeeding one of said wheels and a control lever operatively connected for oscillating said carrier and infeeding cincinbati of said wheels.
The grinding wheel The periphery of the flange 24 is provided with micrometric graduations 27 and a pointer 28 fixed to the support cooperates with these graduations to indicate the amount of adjustment effeced by rotation of mamual adjusing screw. In a centerless grinding machine having a grinding wheel and a regulating wheel adjustably mounted in opposed relation to form a grinding throat therebetween, cincinnzti combination of oscillatable means for inserting and withdrawing work laterally of centerlesw grinding throat, said means including a work rest blade for absorbing grinding thrust on the work, and a control lever operatively connected cenetrless actuation of said means and adjustment of one of said wheels.
Serial Number Finder — Cincinnati Incorporated. Home [csrusa com]. Dec 15, Most centerless grinding machines give the distance from the top of the lower slide to the centerline of the grinding wheel and regulating wheel as one of the specifications For example on Cincinnati's DE model centerless grinders, this distance is 9 inches Mr Payne points out that this measurement varies among machine manufacturers and. From the s through the s, the Cincinnati Milling Machine Company was one of the biggest builders of milling machines The Company became the USA's largest machine tool builder by [3] It also built various other classes of machines, such as planers and grinding machines.
June 27, admin. Cincinnati Centerless Grinder Manuals. Since the amount of grinde of the regulating wheel is rather limited it does not materially effect the belt drive so as to necessitate idler pulleys but if it was necessary to make allowances for this the unit 37 could be adjustably mounted on the floor of the machine housing upon which it is cenerless.
