U-Bolt Clamp Construction

US Patent:
4602811, Jul 29, 1986
Filed:
Nov 28, 1984
Appl. No.:
6/675570
Inventors:
John E. Heckethorn - Dyersburg TN
Danny J. Whittle - Newbern TN
Assignee:
Heckethorn Manufacturing Company - Dyersburg TN
International Classification:
F16L 1314
US Classification:
2853822
Abstract:
A new open end pipe or tube clamp assembly having an exceptionally high strength-to-size ratio which utilizes a U-bolt and a novel saddle member. The saddle is formed by a progressive die of a single piece with no welding and has a top web surface which is severely formed to define a pair of spaced rounded ridges and a depressed central portion achieving high strength and the ridges also serve as nut seats and reduce galling. The side walls of the saddle are centrally depressed to provide narrow contact with the tubing. When the clamp is tightened about a pipe joint high tension stresses force the side members toward each other.

Gas-Tight Exhaust Clamp For Tubing Slip-Joints

US Patent:
4365392, Dec 28, 1982
Filed:
Nov 13, 1978
Appl. No.:
5/960036
Inventors:
John E. Heckethorn - Dyersburg TN
Assignee:
Heckethorn Manufacturing Company - Dyersburg TN
International Classification:
A44B 2100, F16L 2500
US Classification:
24256
Abstract:
A ring clamp capable of forming a gas-tight 360. degree. indentation in a tubing slip-joint, the structure comprises a circular cross-section which is discontinuous over a minor portion of its circumference and has a threaded bolt leg extending from a first end thereof. A tightening lug member comprised of a cylindrical tubular housing and having a planar web extending from one side thereof fits within the discontinuity in the ring, the bolt leg extending freely into the tubular housing and the other end of the ring being welded to the planar web. An inner edge of the web is arcuately formed to continue the circular arc of the ring within the discontinuity, the arcuate surface thus formed being continued by arcuately edged flared portions of the tubular housing located at the entry end of said housing where the bolt leg extends into said housing. The inner perimetric surface of the ring at said entry end lies effectively at the same point on the inner circular arc defined by the ring clamp as the innermost distal corner edge portions of the flared portions, the bolt leg being supported against outward radial movement at this locus within the tubular housing. A nut fitting on the threaded end of the bolt leg and torqued against the exit end of the housing reduces the inner circumference of the ring clamp to impress a bead in a tubing slip-joint over which the ring clamp has been fitted, the bead being formed by the pressure of the ring, the inner arcuate surfaces of the web, and the flared portions of the tubular housing, thereby to form the gas-tight joint and to secure the tubing portions together.

Motor Vehicle Garaging Safety Methods, And Apparatus And Systems

US Patent:
4665378, May 12, 1987
Filed:
Jun 10, 1985
Appl. No.:
6/742788
Inventors:
John E. Heckethorn - Dyersburg TN
Assignee:
3900 Corp. - Baltimore MD
International Classification:
G08G 114
US Classification:
340 51
Abstract:
A signal light is projected in a concentrated beam downwardly when a garage door is fully opened to provide a light spot on the garage floor where no vehicle obstructs it and on the vehicle, such as on the dashboard thereof, when a vehicle is at a properly parked position in the garage. This provides signals both that the door is fully open, indicating that it is safe to exit or enter the garage as well as that the vehicle is in the proper position for parking. In addition, the light source itself may be arranged to glow visibly to an operator outside the garage as a further indication that it is safe to enter. Adjustable bracket means enables the location of the signaling lamp and signal-like spots to be adjusted. The light source is controlled by the position of the garage door, so as to only be illuminated when the door is fully opened. The signal lamp may be controlled by a separate normally open switch closed by the garage door when in the fully opened position thereof or may be tied into and controlled by the circuitry of the garage door operator and by the conventional limit switches, which may be modified, if necessary, to provide a normally-open contact pair for full open position of the door.

U-Bolt Clamp Saddle

US Patent:
3955250, May 11, 1976
Filed:
Nov 19, 1974
Appl. No.:
5/525225
Inventors:
John E. Heckethorn - Dyersburg TN
Assignee:
Heckethorn Manufacturing Co. - Dyersburg TN
International Classification:
B65D 6300
US Classification:
24277
Abstract:
A saddle for a U-bolt clamp is constituted of a pair of tubular housings arranged to receive and slide axially upon the legs of a U-bolt having a semicircular bight, with the housings connected by a web portion consisting of a pair of parallel planar sections of sheet steel welded together in full face contact and extending transversely between the housings integral therewith. The upper (bight facing) edge of each planar section is curved as a semicircular recess curved on the radius of the U-bolt bight. The lower portion of each planar web section is, for the major portion of its length between the tubular housings, doubled back upon itself in flat face contact with the outer face of its associated planar web section, thus providing a double thickness for each web section throughout the area covered by the double back portion and materially reinforcing the entire web portion of the saddle both horizontally and vertically with four thicknesses of the sheet steel from which the saddle is made. The upper edge of the doubled back reinforcement is spaced distally below the bottom of the semicircular recess of its associated web section and is formed with an outturned lateral flange over its full length, which flange lies in a plane normal to the longitudinal axes of the tubular housings and additionally reinforces its web section against horizontal distortion when securing nuts threaded on the ends of the U-bolt legs are drawn up against the lower end faces of the tubular housings to tighten the clamp.
