TYPE-WRITER CARRIAGE.

Specification of Letters latent. Patented Aug. 9, 1910. Original application filed October 22, 1803, Serial No. 118,102. Divided and this application filed January 19, 1904. Serial No. 189,725.

To ctlhvko'm may concern:

Be it known that I, FERDINAND G. Srnrp v MAN, a citizen of the United States, residing at San Francisco, in the county of San F rancisco and State of California, have invented certain new and useful Improve ments in Type-lvriter Carriages; and I do hereby declare the following to e a full, clear, and exact descriptionlof the invention, such as will enable others skilled in the art to which it appertains to make and use the same. p

While my invention is susceptible of general application, it is particu arlv adapted for typewritin machines of small com ass or narrow widt 1, inwhich it is desirab e to employ short papet-h'olders or carriages and yet to use wide'sheets of paper; such, for example, as illustrated and described in my prior application for patent, for an im-,

proved type-writing machine, filed October 22, 1903, Serial No. 178102, of which the My im proved carriage or paper-holder is, alsoillustrated and described but not specifically claimed in' another pending application filed by me November 23, 1903, Serial No. 182308, for improvements in feed-mechanism for type-writer carria es.

The principal object o the present invent-ion is to provide an improved and excmdin ly eiiicient carriage or paper-holder,

witht e various necessar adjuncts and adusting devices, of smal dimensions and adapted 'for successful use 111 machines of .the above mentioned character, and adapted for holding comparatively wide sheets of paper and moving them across the machine so that the Whole width of the paper can be printed. a

The invention will first be. described with reference to the accon pany lng drawings, which are to be taken as a part of this specification, and will then be recited concisely in the annexed claims.

In said drawings'r'Figure 1 is a, to I planview of a portion of the base or be plate,

of a type-writing machine equipped with a carriage embodyi-n my invention. Fig. 2 is aback view of t e same. Fig. 3 is a detail view of a device for preventing an ad: justing rod of the carriage from being pushed back into a hollow inclosure or paper-feed-roller after it has been pulled 'out therefrom. Fig. 4 is a side elevation, or

a View looking toward the right-hand end of the carriage. Fig. 5 is a vertical cross section through the carriage.

As before stated, my present invention is admirably adapted for use iii a type-writer of the character illustrated and described in 1 my pending application Serial No. 178102,

are capable as well of general application.

For the sake of clearly understanding the functions and-relations of the invention as illustrated, it may bestated here that my abo've-- mentioned typew-riting. machine has an actuating mechanism mountedon a suitable'bas or bed-plate, such as represented in'the drawings-fragmentarily and .designated by the numeral 1, and has a rotatory type-wheel or segment which after turning to bring the proper type for'impression into place .impinges or strikes upon the paper, which may rest on a suitable pa er-support, such, for example, as indicate at 2, the printing space of which is shown slightly raised above the top surface of the rest of the paper-support .to..prevent smearin or blurring the paper by thetype-whee or inking ribbon.

My improved carriage or paper-holder,

designated herein b the symbol 3, is shown in the form bf a ollow roll or cylinder, suitably mounted for transverse travel or reciprocationacros's' the machine, havin in the present instance flan es supporte in. grooved guide-ways 4 an .5.. The guideway 4 isrepresented at the rear'of the base 1, and it may be anintegral or attached part of .a scale (S'whichmay be a desirable adjunct inconnection with a pointer 7 on the carriage, The other .guide;way 5, and also the paper-sup ort 2, are siiqwn mounted on ,afT-s haped p ate 8 extending from the under side of the base.

The roll or cylinder 3 has alongitudinal slotor opening, extending preferably along its entire length, so that a sheet or number of sheets of paper although wider than the len h of the roll, may be inserted and r01 ed therein. -A sheet so inserted and rolled in the cylinder is represented in Fig. 5. The roll ne'ed'not be very long, and

however narrow the machin'emiay be 2- se n-e roll need be no longer; yet wide sheets may be placed therein and printed practically all the way across, since the carriage may travel considerably over half its length be 5 yond each side of the base. Instead of a cylindrical roll, other desirable forms may be adopted for example an elliptical or flattish shape, which is particularly desirable in a machine for type-writing cards which are too stiff for rolling.

The sheet of aper may be fed into and out of the slitted roll or cylinder by coacting rollers 9 and 10, preferably having rubber or other gripping surfaces, mounted on and movable with the carriage. The upper .roller is shown carried by-a plate 11 pivoted at 11* to the roll or cylinder; and by means of a latch 12 screwed or pivoted to the roll and projectin; through a slot or opening in said plate and engaging the latter, said plate may be borne upon with more or less pressure by turning the latch to difl'erent positions, thus furnishing means for adjustment of the pressure between the rollers.

The latch is simply so arranged that in -turningtoward the pivoted or attached end of the plate it bears harder, by reason of the relationof the inclined plate to the contact part of the latch.

One roller, here the lowerone, is preferably hollow and has an operating or shift rod 13, which may bekeyed or splined therein as shown in Fig. 5, or which may have its inner end split and expanded to clutch therein, and which at its outer end is provided with a knob or handle. When the machine is not in use, or when it is closed up for packing or storing, the rod 13 may be pushed all the way into the roller,

so as to reduce the dimensions; but when in operation thetrod may be pulled out for manipulating-the rollers, to insert the paper into the .roll, to feed the aper gradually outfrom the roll, to space rom one line of typewritin to another, and also 'to shift the carriage. uitable means may be provided to prevent the rod from being pushed back into the carriage, such as a spring-actuated dog or pawl 14, which may engage an annular groove in the rod when it is pulled out. After the completion of each step-bystep travel of the carriage to the left, the operator shifts or pushes it back to the other side of the machine by means of the rod 13, until its movement is limited by abutment of a lug 15 on the carriage against a pin or stop 16. Healso turns said rod to space the paper or to bring a new. line'for writing into place, and means are preferably furnished for regulating the feed of the paper, or the spaces between the lines of writ-mg. For'instance, the rod 13 may be provided with a pin-wheel or star-wheel 17, having equidistant pins 01' teeth. lVhen the oper- 55 ator shifts the carriage clear to the right,

across the machine.

the carriage.

the pin-wheel straddles a stationary springpressed dog or pawl 18, and the operator then turns the knob of the operating rod to cause one of the pins to. ride against said dog, as indicated by dotted lines in Fig. -5, until this action is limited by abutment of the dog against a stop 19. On-operation of the key-board, the carriage begins to move to the left again, thus carrying the in- .Whcel away from the dog and allowing it to in connectionwith the carriage, for, imparting thereto the necessary step-by-ste travel Mechanism or this purpose, especially adapted for type-writing machines oft he character hereinbefore mentioned, is. illustrated and described but not specifically claimed in my aforesaid application Serial No. 178102, and the same is described and claimed in my other. aforesaid application Serial No. 182308. As set forth in these applications, the feed-mechanism filocated in a recess in the back of the base 1, and embodies in connection with a suitable carriage-spring and escapement a tight cord or flexible connection passing around a pulley or pulleys, actuated by the spring, and crossing itself and havin its opposite ends connected. to opposite en s of Such mechanism, not forming a part of the subject-matter of the pres ent invention, and being fully disclosed in the aforesaid cases, need not be shown nor further referred to herein.

The invention'is susceptible of various modifications in details of structure and arrangement, as well as, embodiment in different machines, so that I do not confine myself to the specific construction illustrated.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent of the United States, is:
