Abstract
A scraper apparatus, having a principal elongated housing; a handle member attached to a first end of the housing; a blade extending from the second end of the housing; a rod within the housing upon which the blade is mounted; a pneumatic power source for powering reciprocating movement of the rod means to impart reciprocating movement of the scraping blade; and a spring interconnecting the power source and the reciprocating rod to provide the reciprocating motion of the rod when power is applied thereto. The apparatus further comprises a support member along the length of the housing to magnetically secure the housing to a surface so that the weight of the apparatus is supported by the support member.
Claims17
A scraper apparatus, comprising:
- a) a principal elongated housing;
- b) a handle member integral to a first end of the housing;
- c) blade means extending from the second end of the housing;
- d) drive shaft means within the housing upon which the blade is mounted;
- e) pneumatic power means for powering reciprocating movement of the drive shaft means to impart reciprocating movement of the scraping blade;
- f) means interconnecting the power means and the reciprocating drive shaft to provide the reciprocating motion of the shaft when power is applied thereto;
- and
- g) support means secured along the length of the housing for securing the housing to a surface to support the weight of the apparatus during use.

A scraper apparatus, comprising:
- a) a principal elongated housing;
- b) a handle member integrally attached to a first end of the housing;
- c) removable blade means extending from the second end of the housing;
- d) a drive shaft extending through the housing secured to a scraping blade at a first end and to a reciprocating drive assembly on its second end;
- e) pneumatic power means for powering the reciprocating movement of the drive shaft to impart reciprocating movement to the scraping blade;
- f) spring means interconnecting the power means and the drive shaft to provide the reciprocating motion of the drive shaft when power is applied thereto;
- and
- g) a support member along the length of the housing to magnetically secure the housing to a surface so that the weight of the apparatus is supported in part by the support member.
