Abstract
Abstract A foreign currency converter consisting of an elongated body carrying a series of parallel longitudinal removable currency scale strips including a United States dollar scale strip, with the dollar currency values aligned with the corresponding foreign currency values. A slide with an index line is mounted transversely on the body for aligning the respective corresponding currency values. The scale strips have lugs providing a snap fit with apertures in the body. The original scale strips can be readily removed and replaced and corrected currency scale strips when there are changes in the currency exchange rates.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
A currency conversion device comprising a substantially flat supporting body, a plurality of currency value scale members on said body adjacent each other, the scale members being provided with respective scales of money indicia, the scales representing the relative numerical values of the currencies of different countries, an index member having a reading element overlying and extending normal to said scales, and means supporting said index member for movement along said scales, whereby a conversion value for a numerical amount on one of said scales can be found visually on another of said scales by viewing along said reading element, and wherein said scale members comprise relatively narrow flat members, each provided with at least one locking projection, said supporting body being formed with apertures lockingly and detachably receiving said projections.
Claim 2
Dependent Claim
131 words
A currency conversion device comprising a substantially flat supporting body, a plurality of currency value scale members on said body adjacent each other, the scale members being provided with respective scales of money indicia, the scales representing the relative numerical values of the currencies of different countries, an index member having a reading element overlying and extending normal to said scales, and means supporting said index member for movement along said scales, whereby a conversion value for a numerical amount on one of said scales can be found visually on another of said scales by viewing along said reading element, and wherein said scale members comprise relatively narrow flat members, each provided with at least one locking projection, said supporting body being formed with apertures lockingly and detachably receiving said projections.
Claim 3
Dependent Claim
31 words
The currency conversion device of claim 1, and wherein said supporting body is of elongated shape and said scale members comprise respective strips arranged in parallel relationship on said supporting body.
Claim 4
Dependent Claim
29 words
The currency conversion device of claim 2, and wherein said index member comprises a bar element having end hook-like flanges slidably engaged on opposite edges of the supporting body.
Claim 5
Dependent Claim
28 words
The currency conversion device of claim 3, and wherein said inde element is of transparent material and said reading element comprises a line inscribed on said index element.
Claim 6
Dependent Claim
33 words
The currency conversion device of claim 2, and wherein the locking projections have enlarged outer head portions and said apertures are dimensioned so that said projections have a snap fit with said apertures.
Claim 7
Dependent Claim

The currency conversion device of claim 7, and wherein said flat supporting body is substantially rectangular and has transverse opposite end edgeS and parallel opposite longitudinal edges, the strips extending substantially parallel to said longitudinal edges and having their opposite end edges substantially flush with the transverse end edges of said supporting body, whereby the ends of the strips are exposed and can be at times pried away from the supporting body to disengage the strips from the supporting body.
Claim 10
Dependent Claim
31 words
The currency conversion device of claim 8, and wherein said supporting body is provided with outwardly flaring circumferential flanges around said apertures defining sockets to lockingly receive said outer head portions.
