Scissors Jack
US Patent:
4802653, Feb 7, 1989
Filed:
Nov 16, 1987
Appl. No.:
7/121165
Inventors:
Darryl L. Engel - Laotto IN
Assignee:
Universal Tool & Stamping Co., Inc. - Butler IN
International Classification:
B66F 308
US Classification:
254126
Abstract:
A scissors jack which has channel link members formed with slots which can be placed over rivets in the jack which have previously been staked in the base or the cap without the channel or link members. The invention relates in an improved jack which can be assembled quicker and easier since holes do not have to be formed in the channel members and the rivets inserted through such holes. The slots formed in the links are such that the links can be placed on the rivets and then rotated and then the free ends of the links are connected together with pivot pins and trunions during which time the links are rotated which locks the links to the rivets in the base and the cap so as to prevent the links from being withdrawn from the base or the cap.
Screw Designs For A Scissors Jack
US Patent:
5312088, May 17, 1994
Filed:
May 21, 1993
Appl. No.:
8/064463
Inventors:
Darryl L. Engel - LaOtto IN
Assignee:
Universal Tool & Stamping Co., Inc. - Butler IN
International Classification:
B66F 312
US Classification:
254126
Abstract:
An improved scissors jack which has a lead screw that does not extend beyond the confines of the jack when the jack is in the partially raised position so as to reduce the space required for storing the jack. A hollow member is formed with a slot in which the extension of the threaded screw is received so that the end of the screw can slide in the slot when the jack is in the unloaded position to allow the jack to be raised to a mid height condition for storage. Under use, the extending portion of the screw moves to the end of the slot in the hollow member so as to apply tension to the lead screw to thus raise and lower the jack as the lead screw is rotated. A modified form of the invention utilizes an extended hollow trunion which prevents the end of the lead screw from extending beyond the confines of the trunion and a further modification provides for pivotally connecting two portions of the lead screw so that the jack can be moved to a stored condition.
Automotive Ratchet Wrench
US Patent:
5325743, Jul 5, 1994
Filed:
Jun 4, 1993
Appl. No.:
8/070909
Inventors:
Darryl L. Engel - LaOtto IN
Assignee:
Universal Tool & Stamping Company, Inc. - Butler IN
International Classification:
B25B 1346
US Classification:
81 61
Abstract:
The present invention comprises a ratchet wrench which has a pawl and spring arrangement such that the pawl's rotational movement is limited when out of engagement with the ratchet wheel so as to assure that the spring does not become disengaged from the pawl to render the wrench inoperative. The spring is provided with a pivotal action which eliminates loading on the end of the spring and provides more desirable spring action.
Lift Cap For A Jack
US Patent:
5135201, Aug 4, 1992
Filed:
Jul 1, 1991
Appl. No.:
7/723564
Inventors:
Darryl L. Engel - LaOtto IN
John R. Scoville - Butler IN
John R. Scoville - Butler IN
International Classification:
B66F 322
US Classification:
254126
Abstract:
An improved lift cap for a jack which comprises a two-piece lift cap that fit together with tab and slot arrangements and which allow the overall mass of the jack to be substantially reduced by allowing the width of the base and channels to be reduced. The improved lift cap has a raised portion which serves as a stop to align the jack and which also provides additional support to lift a vehicle which is being lifted by the jack.
Drive Head For A Scissors Jack
US Patent:
5064171, Nov 12, 1991
Filed:
Sep 24, 1990
Appl. No.:
7/587068
Inventors:
Darryl L. Engel - LaOtto IN
Assignee:
Universal Tool & Stamping Co., Inc. - Butler IN
International Classification:
B66F 312
US Classification:
254126
Abstract:
A drive head for the screw of a scissors jack which is formed in the shape of a wing nut which has a hexagonal socket formed between opposed walls so that a conventional folding lug wrench can be used by inserting its hex tube into the hexagonal socket to drive it. In the event of overload, the lug wrench will slip relative to the wing nut so as to prevent excessive loads and stresses upon the jack.
Scissors Jack Which Has Improved Formed Gear Teeth
US Patent:
5110091, May 5, 1992
Filed:
Jul 29, 1991
Appl. No.:
7/737210
Inventors:
Darryl L. Engel - LaOtto IN
John R. Scoville - Butler IN
John R. Scoville - Butler IN
Assignee:
Universal Tool & Stamping Co. - Butler IN
International Classification:
B66F 312
US Classification:
254126
Abstract:
A scissors jack which has improved formed gear teeth which allow a jack to be retracted to a very low profile so that it can be placed under the vehicles. The teeth of the lower pivot arms are formed so as to extend one direction and the teeth of the upper pivot arms are formed so as to extend in the opposite direction from the teeth of the lower pivot arms so that when the jack is in the down position, the gear teeth on the upper and lower pivot arms can pass each other and thus allow the jack to have a very low contour.
