Pool Table Ball Return Controller
US Patent:
5302154, Apr 12, 1994
Filed:
Sep 9, 1991
Appl. No.:
7/756892
Inventors:
Robert D. Sundstrom - Biwabik MN
Robert L. Thomas - Virginia MN
Robert L. Thomas - Virginia MN
Assignee:
Nortech, Inc. - Virginia MN
International Classification:
A63D 1500
US Classification:
473 24
Abstract:
A pool table ball controller is programmable to vary time, cost, and other parameters relating to money-operated pool tables. A piano-hinge-type guard retains the balls and is operated by an electric motor driving a linkage to raise and lower the guard. Since the electric motor can be stopped in the lowered position, timed pool play can be selected so that the balls will continue to return to the user rather than being retained. The controller can be used to select between timed and rack play for a user of the pool table or may be moved into a programming mode wherein operators of the table can set time parameters relating to length of time for timed play and costs for both timed and rack play. In addition, diagnostic and other messages are displayed on an LCD screen. The controller also allows for programming in periods of time wherein cost and time are varied and when limits may be placed on time play and also periods when either timed or rack play are prohibited.
Apparatus For Lifting And Moving An Article
US Patent:
5405236, Apr 11, 1995
Filed:
Feb 25, 1994
Appl. No.:
8/202407
Inventors:
Robert D. Sundstrom - Gilbert MN
Robert L. Thomas - Virginia MN
Robert L. Thomas - Virginia MN
Assignee:
Nor-Tech B.S.M.I., Inc. - Virginia MN
International Classification:
B66F 900, B60P 100
US Classification:
414495
Abstract:
The present invention is an apparatus that can be operated by one person to move an article such as a pool table, vending machine, and the like, from place to place over a floor surface. The apparatus is made of a planar base and planar platform with a structure for slidably moving the apparatus across the floor. The apparatus includes a mechanism for pivotally connecting the base and platform attached at opposing sides of the apparatus. The pivotal connecting mechanism is operable to raise and lower the platform relative the base to selectively move the apparatus between a retracted position and an elevated position. The invention further provides a method of moving an article using the apparatus. In use, an operator positions the apparatus in the retracted position underneath the article and pushes downward on the handle of the movement actuating structure to elevate the platform which then contacts the article and raises it off the floor. The article is then moved to a new location, and the platform lowered to place the article onto the floor.
