VERTICAL-SPACE REGISTER FOR TYPEWRITERS.

Application led April 2,

To all 'whom 2715 may concern Be it known that I, Lorn R. FULTON, a citizen of the United States, residing at Huntington Park, in the county of Los Angeles and State of California, have invented new and useful Improvements in Vertical-Space Registers for Typewriters, of which the following is a specification.

My invention relates to vertical space registers for typewriters and consists of the novel features herein shown, described and claimed.

An object is to provide a vertical spaceregister to be used in predetermining the space to be covered by the typewriting work and means for indicating that the space has been covered.

Other objects and advantages will appear from the drawings and specification.

The drawings illustrate the invention. h

Figure 1 is a fragmentary front elevation of `a typewriter provided with a vertical space register in accordance with the principles of my invention, the parts being broken away and shown in section.

Fig. 2 is a fragmentary end elevation looking in the direction indicated by the arrows 2 in Figs. 1 and 3.

Fig. 3 is an enlarged sectional detail on the line 3-3 of Fig. 2.

Fig. 4 is a sectional detail on t-he line 4-4 of- Fig. 3.

The details of the vertical space register `,for typewriters shown in the drawings are as follows:

The typewriter `platen 1 is mounted upon a shaft 2, which may be operated by a hand wheel 3. The shaft 2l extends through a frame bearing 4 and the hand wheel -3 has a hub 5 fitting upon the end of the shaft 2 outside of the bearing 4 and held removably in place by set screw 6.

In applying the vertical space register the screw 6 is loosened and the hand wheel 3 removed and a Spur gear 7 is rigidly mounted as by a key 8 upon the shaft 2 against the bearing 4 and the hand wheel 3 may be replaced. The bar 9 carrying the bearing 4 extends forwardly to make the register supporting bar 10, and an attaching tension plate 11 fits against the leftl hand side of the bar 9 and is secured in place by screws 12 inserted through the plate and tapped into the bar. They housin 13 is carried by the attaching plate 11 an has side plates 14 and 1924. Serial No. 703,690.

15 above the supporting bar 10, a web 16 extending inwardly from the lower part of the plate 15, an extension side plate 17 extending downwardly from the web 16 and a second web 18 extending outwardly to the plate 14.

A spur gear 19 is mounted against the extension plate 17 and turns upon a screw 20 tapped into the plate 17 and the gear 19 meshes with the gear 7. A third gear 21 fits against the inner face of the plate 14 and is mounted loosely upon a shaft 22 having an operating hand wheel 23 upon its outer end. The register or indicating wheel 24 is nonrotatively mounted upon the squared portion 25 of the shaft 22 between the gear 21 and the plate 15 and a nut and washer 2G is mounted upon the inner end of the shaft 22 against the plate 15. A spring pressed pin 27 is mounted in a bore extending from the left hand face of the wheel 24 and bears against the face of the gear 21 to make a frictional drive for the register wheel 24 so that by manipulating the hand wheel 23 the register 24 may be set as desired and then driven b friction from the platen shaft 2.

lndicating or register numbers 28 are formed upon the periphery of the wheel 24 and are visible one number at a time through -the opening 29 in the web 16. The wheel 24 is o f such a size geripherally and the

gear train

21, 19 and is so proportioned that one revolution of the wheel 24 will equal' eleven inches upon the sheet of paper 30 passing through the typewriter and the numbers 28 reading from one to eleven around the wheel anti-clock wise when seen as in Fig. 2, each number on the wheel representing an inch on the typewriter paper.

A bell post 31 extends to the right from the upper part of the plate 15, the post being rigidly screwed into the plate and the semispherical bell 32 is mounted upon the post 31 and has a lug 33 extending inwardly from its edge. A bell clapper 34 is adapted-to strike the lug 33 and has an arm 35 extending from the clapper 34 along side the plate 15 and tlie bent at right angles and extending through the plate 15 to form a pivotal Support 36 and then bent downwardly inside of the plate to form the operating arm 37. A pin 38 projects from the right hand face ofthe wheel 24 to engage the arm 37. The pin 38 is so located relative to the numbers 28 that the time at which the bell will ring may be accurately determined by used, the hand wheel 23 will bell mani ulating If it is desired to work upon an 'ordinaryl sheet of paper thirteen inches long, the paper will be placed in position around the platen 1 so as to leave a margin of one inch at the top and then the hand wheel 23 manipulated to bring the number eleven into position to be seen through the opening 29. Then when the work proceeds until eleven inches, of aper have been covered the number one wil appear through the opening 29 and the 32 will ring to indicate that the work has reached to within an inch ofvthelower edge of the paper and has covered a space of eleven inches. v

Where a. di'erent size of paper 1s being be operated to indicate tenor nine or eight or any other desired number of inches to be covered by the typewriting work, and as the work proceeds to the endthe bell 32 will ring.

Thus, I have produced a device to be made either as a part of a typewr1ter or as an attachment to a typewriter, and which may be set to predeterminethe vertical space to be covered on a sheet of typewriting and to indicate visibly and .audibly when the space has been covered.

Various changes maybe made without departing from the spirit of my invention as claime I claim:

1`. A space register for typewriters having a platen and a platen sha t, an indicating Wheel rigidly mounted on gear rotatably mounted on the indicating wheel shaft, a gear drive from said gear to the platen' shaft, and a frictional connection between the indicating wheel and the gear on the indicating Wheel shaft whereby the indicating wheel may be set independent of the rotation of the platen.

2. A space register for typewriters having a platen and a platen shaft, an indicating Wheel rigidly mounted on a shaft, a loose gear rotatably mounted on the indicating Wheel shaft. a gear drive from said gear to the platen sha-ft, a frictional connection between the indicating wheel and the gear on the indicating wheel shaft whereby the indicating wheel may be set independent of the rotation of' the platen whereby a visible signal is given, and means actuated b v the rotation of the indicating wheel for giving an audible signal.

In testimony whereof I name to this specification.
