Abstract

Many large machines, including large xerographic copiers/printers, are provided with caster wheels for facilitating transportation and movement thereof. However, in situations where such large machines must negotiate a ramp during delivery or removal, the usefulness of such caster wheels is limited to the ramp angle of the machine, defined as the angle formed between a support surface base pan upon which a caster wheel rests and the line extending from the caster wheel to the extreme edge end of the base of the machine. Referring to FIG. 1, the ramp angle is shown by angle R2. The ramp angle determines the maximum angle which a machine can ascend or descend without interference between the bottom of the machine and the ramp. The ramp angle measurement tool of the present disclosure provides a means for quickly and accurately measuring the ramp angle.

RAMP ANGLE MEASUREMENT TOOL (Cont'd)

Many large machines, including large xerographic copiers/printers, are provided with caster wheels for facilitating transportation and movement thereof. However, in situations where such large machines must negotiate a ramp during delivery or removal, the usefulness of such caster wheels is limited to the ramp angle of the machine, defined as the angle formed between a support surface base pan upon which a caster wheel rests and the line extending from the caster wheel to the extreme edge end of the base of the machine. Referring to FIG. 1, the ramp angle is shown by angle R2. The ramp angle determines the maximum angle which a machine can ascend or descend without interference between the bottom of the machine and the ramp. The ramp angle measurement tool of the present disclosure provides a means for quickly and accurately measuring the ramp angle.

The ramp angle measurement tool of the present disclosure is shown in FIG. 2 wherein it can be seen that an elongated base member 4 is joined to a swing arm 2 via a hinge 8. A calibration rod 6 is pivotably coupled to base member 4
at an end opposite hinge 8. Swing arm 2 includes a receiving aperture 3 so as to form a variable triangle defined by members 2, 4 and 6. The...
