A further object is to provide a belt drive of this character with a control member positioned exteriorly of the outline of the bench. A further object is to provide a belt drive of this character with novel means for selectively locking the same in operative and inoperative relations. A further object is to provide a belt drive of this character with novel belt tightening means.
2,138,117	Nov. 29, 1938	Belt Tighener	John J. O'Brien	South Bend, IN	Oltsch & Knoblock - patent attorneys John J, O'Brien and The Northern Trust Co. executors of said Miles W. O'Brien (deceased). This invention relates to belt tighteners, and more particularly to belt tighteners for lathes, which are preferably provided with a horizontal, drive belt actuated by an independently mounted countershaft assembly. The primary object of the invention is to provide a simple device of this character by which a shiftable countershaft mechanism may be locked in either belt tensioning or belt releasing position. A further object is to provide a device of this character constructed whereby the tension applied thereby to a drive belt may be accurately adjusted. A further object is to provide a device of this character in the nature of a toggle provided with a stop to limit pivoting thereof in one direction at substantially dead center. A further object is to provide a substantially upright pivoted countershaft mechanism shiftable by a foldable member either against the tension of a drive belt to substantially balanced position upon extension of said member, or oppositely to unbalanced position in the direction of a driven member whereby the weight of said countershaft mechanism assists in locking or maintaining said foldable member in folded position. A further object is to provide a device of this character comprising pivotally interconnected parts, the pivot end of one of said parts having a jaw in which the other part is received to limit the degree of relative pivoting of said parts. A further object is to provide a device for selectively applying or releasing tension of a drive belt comprised of pivotally interconnected parts, one of which affords a hand grip for operating the device and is provided with stop members which limit actuation thereof and assist in locking the device in either tension applying or tension releasing position. A further object is to provide a device 'of this character which is simple in construction, readily assembled and applied, and comparatively inexpensive.

D118,930	Feb. 13, 1940	Lathe or Similar Article	Russel E. Frushour	South Bend, IN	Oltsch & Knoblock - patent attorneys
2,245,471	Jun. 10, 1941	Friction Clutch for Lathe Aprons	George L. Garvin	South Bend, IN	Oltsch & Knoblock - patent attorneys This invention relates to improvements in friction clutches for lathe aprons, and more .particularly to a clutch on the lathe apron which is intended to establish a driving connection between two parts of a gear train which are normally free for relative movements. The gear train is driven by the lead screw of the lathe, and is selectively engageable by suitable gear shifting means with gearing associated respectively with a longitudinal rack on the lathe bed, and with a cress feed shaft controlling the position of a tool carrier transversely of the lathe bed. The gear shifting means requires the use of a clutch for releasing the gearing from driving engagement for its operation. The primary object of the invention is to provide a compact, powerful, simple and substantially wearproof clutch of this character. A further object is to provide a device of this character with an idler gear having a hollow portion and normally freely rotatable on a member constituting another part of a gear train, and a friction clutch including a toggle acting upon a sectional shoe fitting within the hollow portion of the idler gear for the purpose of selectively establishing a driving connection between the idler gear and the remainder of the gear train. A further object is to provide a friction clutch comprising toggle members fitting within a sectional shoe, and means for tilting said toggle members, whereby a slight movement of said toggle members effects expansion of said shoe with great force and power. A further object is to provide a device of this character which will not stick:, and which may be positively and instantly actuated to desired position. A further object is to provide a device of this character having a longitudinally shiftable actuating shaft engaging a pair of toggle members, with said shaft loose in its mounting to permit equalization of the force exerted by the operating toggle members. A further object is to provide a device of this character having a pair of plate segments fitting within a hollow two-piece clutch shoe with their inner ends received in a notch in a longitudinally shiftable actuating shaft.

2,748,624	Jun. 05, 1956	Rotary Table	Otto A. Costello	South Bend, IN	Mann, Brown & Hausmann - patent attorneys My invention relates to rotary fables having a wide variety of uses and applications in machine tools such as shapers, drill presses, lathes, milling machines and the like, as well as being adapted for bench layout work. An object of my invention is to provide a new and improved table that may be more quickly and conveniently rotated from one exact position to another. Another object is to provide a new and improved pivotal support which more accurately and securely holds the table in exact positions and which may be readily adjusted to compensate for wear. Another object of my invention is to provide a new and improved arrangement of scales. Another object is to provide a new and improved means for locking an adjustable scale in various positions. Another object is to provide a new and improved arrangement of gearing for accurately positioning the rotary table.

3,999,264	Dec. 28, 1976	Automatic Turret Head	Bruce Wayne Carmen	South Bend, IN	Craig & Antonelli - patent attorneys Abstract An automatic tool turret for a lathe including a base adapted to be detachably secured to the lathe way. A tool carrying head is mounted on the base for movement between a clutched work performing position and unclutched head rotating position. The movement is hydraulically accomplished so that the head is supported by a hydrostatic bearing created by the hydraulic fluid. The fluid pressures generated during the movement of the head between its clutched and unclutched positions is used to initiate a work performing operation and to initiate turning of the head.
4,218,942	Aug. 26, 1980	Inch/Metric Thread Dial	Dana F. Buccicone	Battle Creek, MI	Oltsch, Knoblock & Hall - patent attorneys Abstract A thread dial for use on English system engine lathes when cutting English or Metric threads.
4,658,859	Apr. 21, 1987	Valve Spool with Cross Drill Ports	Bengt S. Backe	Dundee, IL	Barnes & Thornburg - patent attorneys Abstract A four-way valve is provided, for selectively interconnecting pressure supply and return lines with control pressure lines of a hydraulic device, having means for independently balancing the valve against pressures exerted on the valve by any one or more of the pressure lines and at any operating position of the valve. These pressures exerted on the valve would otherwise restrict or prevent actuation of that valve. This balancing means exposes a minimum surface area of the valve to high pressure forces and isolates the fluid pressure in the pressure lines until interconnection is made by valve actuation.

4,706,456	Nov. 17, 1987	Method and Apparatus for Controlling Hydraulic Systems	Bengt S. Backe	Dundee, IL	Abstract A control system is provided for a hydraulic actuating system having a multi-phase stepping motor with a driver therefor which supplies and controls DC current through each of the motor windings such that no current is induced into the control winding from adjacent windings. The stepping motor precisely controls the rotation of an eccentric cam engaging an actuating plunger which actuates a control valve of the hydraulic actuating system. The driver receives control signals from a computer programmed to calculate, from user input command signals indicative of the desired system condition, and generate those control signals which most quickly achieve a rough approximation of the desired system condition. After this rough approximation is attained, the computer generates new control signals for the driver as a function of feedback signals and/or system component characteristics so as to precisely achieve the desired system condition.
