Filed:

Jan 15, 2004
Appl. No.:

10/758514
Inventors:

William Wollgast - Waller TX, US
James Ellinwood - Houston TX, US
International Classification:

E02F003/76
US Classification:

172817000
Abstract:

An attachment for a skid steer loader, back hoe or powered excavator that can be used to quickly smooth out the walls of a swimming pool, ditch, etc. following the excavation and the process of using the attachment. The attachment includes a vertical flat surface perpendicular to the ground for smoothing the walls of a swimming pool. The process will reduce the need for workers to spend time and effort smoothing the walls manually and improving the safety of swimming pool construction. The cost of building a swimming pool will be reduced significantly by decreasing the number of workers required in the construction process. The process of smoothing walls reduces the amount of gunite required in the swimming pool construction process and thus improving the economics for the pool builder.

Abstract:

This present invention is an attachment for a skidsteer loader, backhoe or other work type vehicle that can be used to quickly form the skimmer box walls when building a swimming pool. This invention significantly reduces the time required to prepare the skimmer box. In addition, this invention improves the safety of swimming pool construction by eliminating this strenuous job for workers and the risk of potential injury while digging the skimmer box hole. This invention reduces the costs of building a swimming pool by reducing the amount of time workers are required in the construction process. In addition, material savings can be incurred by reducing the amount of gunite required in the swimming pool construction process
