Cool Melt Glue
View pageUS Patent:
50414828, Aug 20, 1991
Filed:
Jul 26, 1988
Appl. No.:
7/224384
Inventors:
Robert L. Ornsteen - Key West FL
Peter S. Melendy - Brentwood NH
Dennis J. Fitzmeyer - Epping NH

Assignee:
Adhesive Technologies - Hampton NH
International Classification:
C08L 3104
C08L 9108
C08L 9304
C08L 9108
C08L 9304
US Classification:
524272
Abstract:
Hot-melt adhesives, useful for both glue-port and glue-gun applications, are formulated so that they can be applied at temperatures no higher than 280. degree. F. and preferably at temperatures of at most 250. degree. F. The adhesive compositions have a heat resistance of at least 125. degree. F. and are readily shaped into glue sticks for use in glue guns. The adhesive for the hot-melt adhesive compositions is suitably compounded with tackifyin resin and/or wax. The resulting composition has a shape viscosity profile, which is readily achieved, e. g. , by using a high melt index adhesive polymer as an essential component.
Dispenser For Hot-Melt Material
View pageUS Patent:
50261878, Jun 25, 1991
Filed:
May 17, 1988
Appl. No.:
7/196774
Inventors:
Richard A. Belanger - Kensington NH
Peter S. Melendy - Exeter NH
Robert L. Ornsteen - Key West FL
Peter S. Melendy - Exeter NH
Robert L. Ornsteen - Key West FL
International Classification:
B67D 562
US Classification:
401 1
Abstract:
A dispenser for hot-melt materials, such as adhesives, includes a heat-conductive, removable cartridge containing the adhesive to be melted, a chamber for receiving the cartridge and a heater adjacent the cartridge for melting the adhesive prior to dispensing through a nozzle. Pressure is applied through a plunger to expel the adhesive through the nozzle.
Adhesive Gun Having Needle Valve Nozzle
View pageUS Patent:
42158028, Aug 5, 1980
Filed:
Nov 8, 1978
Appl. No.:
5/958871
Inventors:
Robert L. Ornsteen - Cape Neddick ME
Assignee:
Ornsteen Chemicals, Inc. - Seabrook NH
International Classification:
B67D 562
US Classification:
222146H
Abstract:
A needle valve nozzle is employed in a hot melt adhesive gun used to apply thermoplastic adhesive. Actuation of a trigger mechanism supplies pressurized gas to a nozzle chamber which urges the nozzle in an outward direction to an open position, the needle remaining stationary during operation of the nozzle. Deactuation of the trigger mechanism stops the flow of pressurized gas to the chamber and a vent allows the pressurized gas to flow from the chamber, permitting a spring-biasing mechanism to return the nozzle to a closed position. Pressure on the adhesive can also be employed to urge the nozzle to an open position.
Method For Forming A Hot Melt Adhesive Cartridge
View pageUS Patent:
40934853, Jun 6, 1978
Filed:
May 31, 1977
Appl. No.:
5/801846
Inventors:
Robert L. Ornsteen - Cape Neddick ME
International Classification:
B29D 2304
US Classification:
15624413
Abstract:
A method for continuously forming a hot melt adhesive cartridge having a non-stick, thermoplastic outer coating. The hot melt adhesive cartridge is formed by extruding a sleeve of non-stick, thermoplastic material having a predetermined outside dimension, cooling the sleeve to cause setting of the thermoplastic and introducing a hot melt adhesive into the set sleeve.
Hot Melt Cartridge Adhesive Gun
View pageUS Patent:
40334848, Jul 5, 1977
Filed:
Jan 29, 1976
Appl. No.:
5/653598
Inventors:
Robert L. Ornsteen - Cape Neddick ME
Assignee:
Ornsteen Chemicals, Inc. - Seabrook NH
International Classification:
B67D 562
US Classification:
222146HE
Abstract:
A hot melt adhesive gun employing a cartridge of thermoplastic adhesive contained within a chamber made of a thermally insulative non-stick material. A plunger is driven into engagement with the cartridge by a manually operative trigger actuated infinite resolution ratchet to urge the cartridge into melting contact with an electrical heater block and to provide pressure for driving the melting adhesive into a storage reservoir and out through a valved nozzle for application to a bonding surface. A partially melted portion of the cartridge deforms under the applied pressure of the plunger to form a seal against backflow of molten adhesive. Upon release of the trigger, a retraction mechanism causes the plunger to retract a predetermined amount to disengage the cartridge thereby allowing closure of the nozzle valve and arresting of adhesive flow.

Hot Melt Adhesive Gun
View pageUS Patent:
41990820, Apr 22, 1980
Filed:
May 9, 1978
Appl. No.:
5/904438
Inventors:
Robert L. Ornsteen - Cape Neddick ME
Assignee:
Ornsteen Chemicals, Inc. - Seabrook NH
International Classification:
B67D 562
US Classification:
222146HE
Abstract:
A hot melt adhesive gun capable of dispensing relatively large volumes of molten adhesive and comprising a hot melt chamber and a pressurized air chamber separated by a moveable element which isolates the chambers one from the other. Molten adhesive from an associated bulk supply is fed into the hot melt chamber by means of a supply nozzle temporarily plugged into a valved inlet passage of the gun only when necessary to charge the gun with a fresh supply of molten adhesive. Upon actuation of the gun trigger, pressurized air in the air chamber, drives the moveable element forward to cause adhesive to flow out of the nozzle. Upon release of the trigger, adhesive flow from the nozzle valve is discontinued. The novel gun also includes a pressure relief valve and relief port to allow the escape of trapped gas which can build up in the melted adhesive and which exceeds a predetermined pressure level.
