US Patent:

51996243, Apr 6, 1993

Filed:

Dec 20, 1990

Appl. No.:

7/630904

Inventors:

Charles F. Smart - Danbury CT
William E. O'Connor - Watertown CT
Anthony D'Aquila - Trumbull CT

Assignee:

Emhart Inc. - Newark DE

International Classification:

B21J 1528

US Classification:

227 2

Abstract:

A rivet pulling head is supported for vertical displacement from an up position to a down riveting position. A rivet delivery device is carried by a movable support and has a delivery arm which can be lowered relative to the pulling head and pivoted underneath it to deliver the next rivet to the pulling head. The delivery device is operated when the head is at the up position and while the head is maintained at that location.

Charles F. Smart - Danbury CT

Assignee:

Emhart Industries, Inc. - Towson MD

International Classification:

B21J 1510

US Classification:

227 6

Abstract:

An automatic riveting machine determines that an operator has manually removed a rivet from the nose of the gun by sensing its insertion into the nose and its subsequent absence prior to gun operation.

Filed:

Aug 8, 1990

Appl. No.:

7/564198

Inventors:

Charles F. Smart - Danbury CT

Assignee:

Emhart Inc. - Newark DE

International Classification:

B23P 2100
B23Q 1500

US Classification:

29706

Abstract:

The system accordingly strictly accounts for all rivets and prevents a rivet from being removed for any reason and not accounted for. This assures that no free rivet will find itself within the workpiece being riveted.

Filed:

Oct 16, 1990

Appl. No.:

7/598921

Inventors:

Charles F. Smart - Danbury CT
Anthony D'Aquila - Trumbull CT

Assignee:

Emhart Inc. - Newark DE

International Classification:

B21J 1510
B21J 1528

US Classification:

227 2

Abstract:

A vacuum pulls a spent mandrel through a gun bore and into a collection tube which discharges into a collector. Gun operation and mandrel entry into and departure from the collection tube are sensed and blockage of the mandrel within the collection tube and the jamming of the mandrel in the rivet gun are determined and signalled to the operator. The cycle immediately continues when the mandrel is cleared.

Appl. No.:

8/718280

Inventors:

James Geary - Fairfield CT
Charles Smart - Brookfield CT

Assignee:

Robohand, Inc. - Monroe CT

International Classification:

F16L 2712

US Classification:

2851451

Abstract:

An actuating slide assembly for an automatic assembly machine, wherein the slide assembly includes telescoping fluid conducting conduits interconnected between the slide body and associated end block mounted for relative reciprocal movement relative to the slide body and a sealing arrangement for effecting a fluid tight seal between the relative movable telescoping conduits and associated slide body and end block. The sealing arrangement includes a sealing cartridge and associated O rings circumscribing one of the telescoping fluid conduits intermediate the opposed ends thereof to prohibit any leakage between the relative movable telescoping conduits and the associated slide body and a second sealing arrangement connecting the outer end of a telescoping conduit to its associated end block in a manner to provide a leakproof seal therebetween. The respective sealing arrangements also allow for a limited amount of play or vibration to occur when the slide assembly is in operation without the loss or leakage of fluid pressure at the seals.

Filed:

Dec 23, 1997

Appl. No.:

8/996604

Inventors:

William D. Hylwa - Derby CT
Charles F. Smart - Brookfield CT
Donald P. Viscio - Danbury CT

Assignee:

Emhart Inc. - Newark DE

International Classification:

B21D 905

US Classification:

723914

Abstract:

A ball device for setting blind rivets is provided. The device features one or more rows of balls of at least three balls per row, and a taper section which cooperates with the balls to grip the mandrel of the blind rivet. Upon movement of the taper section, the balls dig into the mandrel to grip, and consequently pull the mandrel in the desired direction. The device features a longer life than similar devices utilizing jaws to grip the mandrel.

Appl. No.:

7/445076

Inventors:

Charles F. Smart - Danbury CT
Raymond H. Varian - Danbury CT
Anthony D'Aquila - Trumbull CT

Assignee:

Emhart, Inc. - Towson MD

International Classification:

B21J 1510

US Classification:

227 3

Abstract:

An automatic riveting machine is disclosed which counts the rivets, as set, to control the feeding of rivets from a feeder to the rivet track or chute. The track will be resupplied after a selected number of rivets are set or sooner should the track become prematurely empty by removal of rivets from the track.

Appl. No.:

7/445079

Inventors:

Anthony D'Aquila - Trumbull CT
Charles F. Smart - Danbury CT
Raymond H. Varian - Danbury CT

Assignee:

Emhart Inc. - Towson MD

International Classification:

B21J 1510

US Classification:

227 2

Abstract:

Rivets are delivered from a feed chute to a transfer location and blown through a feed tube to a loading device. The presence of a rivet is sensed both at the transfer location and at the loading device and a fault indicator is operated in the event a rivet sensed and transported from the transfer location does not wind up in the loading device. The operator hits the reset button which blows clean air thru the feed tube in an attempt to free the jammed rivet. In the event this does not occur, the system assumes the operator cleared the jam and loads the next rivet into position to be transferred and continues the cycle.
