Patent Number	Date	Title	Name	City	Description
975,591	Nov. 15, 1910	Mechanical movement	William A. Whitney	Rockford, IL	This patent was subsequently improved in patent 1,389,565; see that patent for a description of how this patent works.
1,050,583	Jan. 14, 1913	Ratchet Wrench	William A. Whitney	Rockford, Winnebago County, IL	Reversible ratchet using a spring-loaded ball in a conical enclosure as the "pawl." The handle can be rotated a half-turn to control the direction of the ratchet action.

1,065,753	Jun. 24, 1913	Hand Metal Shears	William A. Whitney	Rockford, Winnebago County, IL
1,180,357	Apr. 25, 1916	Beam Punch	William A. Whitney	Rockford, Winnebago County, IL
1,389,565	Aug. 30, 1921	Machine element	John Jensen	Rockford, IL	Improvements to patent 975,591, which is "a punch comprising a bushing, a spindle extending through the busing, the bushing and spindle being helically grooved, a series of balls in said grooves, and a cylindrical spacer or retainer for the balls, said retainer being interposed between the busing and the spindle and provided with holes for receiving the balls. The grooves in the bushing and the spindle are longer than the series of balls, so that the series of balls rotates and moves longitudinally as a body or unit. Among the many uses of punches and shears of the type shown in said Whitney patent is the shearing and punching of metal in connection with the erection of buildings. When employed in and upon buildings under construction, the tools receive extremely rough usage, and lubrication of the tools is very apt to be neglected. The retainer being necessarily formed of thin metal, it is subject to considerable wear under the most favorable conditions, the ball-receiving holes in the retainer becoming elongated as the wear and thus failing in their function of keeping the balls properly spaced apart."

1,473,558	Nov. 06, 1923	Punch	John Jensen	Rockford, Winnebago County, IL	"Hand metal punches are especially adapted for use in building structures where scaffolds are not provided and in other places ordinarily inaccessible. In many places it is frequently desirable that the punch require very little space in which to operated..."

Hydraulic fluid pressure supply apparatus is operable to a first condition supplying fluid pressure to the hydraulic ram actuator to move the ram forwardly, and a stripper clamp spring yieldably urges the stripper sleeve forwardly into clamping engagement with the workpiece as the ram is moved forwardly. The hydraulic fluid pressure supply apparatus is operable to a second condition supplying fluid pressure to the hydraulically operated clamp to clamp the stripper sleeve against movement and to also supply fluid pressure to the hydraulic ram actuator to move the ram to a return position while the clamp holds the sleeve against return movement. A stripper return spring yieldably urges the stripper sleeve to a return position when the ram is in its return position and the hydraulically operated clamp is released.

Benedict	Rockford, Winnebago County, IL	Abstract: A machine for operating on sheet stock workpieces having stock grippers mounted on a work positioning carriage for moving the sheet stock workpiece along first and second relatively transverse paths in the plane of the stock to position the workpiece at predetermined positions relative to the machine tools. Work grippers are mounted on the work positioning carriage for adjustment relative to the carriage when the work grippers are released and the work grippers are automatically clamped against movement relative to the carriage when the work grippers are actuated to grip the stock.
4,879,894	Nov. 14, 1989	Press with Movable Workpiece Support Carrier	Roger J. Benedict	Rockford, Winnebago County, IL	Abstract A press having a work positioning carriage for moving a workpiece horizontally along relatively transverse X and Y axes to position different areas of a workpiece at a work station. Lower forming tools are fixed at the work station and a lower stripper is mounted for vertical movement relative to the lower forming tools. Upper press tools are mounted on the press ram and operative when the ram is moved downwardly to force the workpiece downwardly over the lower forming tools and depress the lower stripper. The lower stripper is yieldably biased upwardly to raise the workpiece off the lower press tools when the upper press tools are raised. A work carrier is mounted for horizontal movement by the work positioning carriage and the work carrier has a workpiece support that is vertically movable relative to the work carrier. A master hydraulic actuator is operated during movement of the ram and is hydraulically connected to a slave fluid actuator mounted on the work carrier and connected to the workpiece support to raise and lower the workpiece support relative to the carrier in timed relation with movement of the ram.

Benedict	Rockford, Winnebago County, IL	Abstract: A bending brake including a horizontal lower clamp jaw, a bending beam mounted for pivotal movement about a horizontal relative to the lower clamp jaw, and an upper jaw carrier mounted for vertical movement into and out of work clamping engagement with the lower jaw. The upper jaw carrier has a plurality of clamp jaws mounted at angularly spaced locations on the carrier and carrier position control mechanism is provided for turning and locking the upper jaw carrier to selectively position different upper clamp jaws in an operational position relative to the lower clamp jaw.
7,762,116	Jul. 27, 2010	Bending Brake Carrier Locking Mechanism and Method	Brian McVey	Machesney Park, Winnebago County, IL	Abstract: A bending brake includes a rotating carrier that is rotatable about a rotation axis. The carrier has first and second upper jaws connected thereto at different angular locations about the rotation axis. A locking mechanism for preventing rotation of the carrier during operation of the bending brake includes an endplate forming a pocket, the endplate disposed adjacent to a distal end of the carrier. A latch having a trigger portion is pivotally connected to the endplate and located within the pocket such that the trigger portion protrudes from the pocket. A toothed cam wheel rotating with the carrier has at least one tooth formed thereon that engages the trigger portion of the latch to prevent rotation of the carrier in one direction at preselected angular positions corresponding to the first and second upper jaws.
