BENJAMIN 0. FOX, OF CHESTER, PENNSYLVANIA.
CAP FOR TYPE-WRITER KEYS.
SPECIFICATION formingpart of Letters Patent N0. 722,006, dated March 3, 1903. Application filed November 5, 1902. Serial No. 130,119. (No model.)
My invention relates to improvements in' caps or heads for type-writer keys, and has for its object to obviate the confusion which arises in having more than one letter or character printed on the same face of a key-cap.
The simple and novel construction employed by me in carrying out my invention is fully described and claimed in this specification and illustrated in the accompanying drawings, forming a part thereof, in which- Figure 1 is a perspective of a keyboard with my improved keys thereon. Fig. 2 is a perspective of one of the improved caps. Fig. 3 is a modified form of the same.
Like numerals of reference designate like parts in the different views of the drawings.
The numeral l'designates a keyboard having a bank of type-keys 2 thereon and two shift-keys 3 and 4., as on the well-known Oliver keyboard. Each of the keys 2 is provided with a cap 5, which comprises a cylindrical portion 5 and a ledge 5", formed on the side of said cylinder. The cylinder 5 is mounted head upward, and this head forms a horizontal face 6, on which a character 7 is printed. The ledge 5 has a face 8 thereon which is inclined toward and fronts the operator of the keys. A character 9, different'from the character 6, is printed on the inclined face 8, which is also colored a diiferent color from that of the face 6.
Two shift-keys 3 and 4 are employed. The key 3 is arranged to be operated to print the upper-case character corresponding to the character 7 on the faces 6, while the key 4 is arranged to be operated to print the uppercase character corresponding to the characters 9 on the faces 8. The cap of the key 4 My improved keys are operated in the same manner as the ordinary keys,-the faces 6 being engaged by the fingers of the operator. The placing of the two characters at an angle to each other greatly reduces the mental effort necessary in writing the correct character, and making the faces of different colors still further decreases this effort. In the modified form the ledge 5 has a horizontal face 9.
I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spiritofrmy invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A key-cap comprising a cylindrical portion having a character on the upper face thereof and a ledge formed on the side of said cylindrical portion and having a face thereon bearing a character, substantially as described.
2. A key-cap having an upturned face hearing a character, and a visible face slightly inclined to the first-mentioned face and having a different character thereon, substantially as described.
3. A key-cap having an upturned face hearing a character, and a visible face slightly inclined to said upturned face and of a different color, substantially as described.
4. Akey-cap having an upturned face bearing a character and a slightly-inclined ledge formed on said cap and bearing a visible character, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
, BENJAMIN 0. FOX.
