TYPE-WRITING MACHINE AND RIBBON-HOLDER THEREOF.

SPECIFICATION forming part of Letters Patent No. 473,718, dated April 26, 1892.

l Application filed November 2, 1891. Serial No. 410,664. (No model.)

To @ZZ whom it may concern:

Be it known that we, GEORGE B. VEBB, a resident of New York city, inthe county of New York and State of New York, and LOUIS N. CHAPIN, a resident of Brooklyn, in the county of Kings and State of New York, citizens of the United States, have invented certain new and useful Improvements in Type-Vriting Machines and Ribbon-IIolders Thereof, of which the following is a specification.

Ribbons for type-writing machines vary greatly in quality both as to fabric and ink or coloring-matter employed, and for this reason some ribbons are considerably more efficient and durable than others. The purchaser or user of ribbons is usually, however, unable to judge of the superiority of one ribbon over another, and hence frequently buys a ribbon of inferior quality supposing it to be of the best make.

Numerous dealers in type-writer supplies sell such inferior ribbons as the ribbons made by the manufacturers of the standard machines especially for their respective machines to the great detriment of the trade and reputation of such manufacturers, and dealers frequently resort to the practice of removing from a wrapper or package bearing the name or businessecard of the manufacturer a standard or first-quality ribbon and substituting therefor a lower grade or poorer quality of ribbon.

Our invention has for its main object to provide a check to such fraudulent and dishonest practices, and thus afford protection to the standard manufacturerand to the consumer who is desirous of purchasing only iirst-class ribbons.

To these ends our invention consists in putting up the ribbon in a box or case of peculiar construction and in constructing the type-writing machine in a peculiar way to reoeive'such box or case, all as will be hereinafter more fully described, and particularly pointed out in the appended claims,

In the accompanying drawings, Figure 1 is a horizontal section of a portion of aRemingtou type-writer, taken on a plane below the top plate of the machine and on about the line .e e of Fig. 2. Fig. 2 is a vertical section taken at the line y y of Fig. 2 with the top plate added. Fig. 3 is an elevation taken at the right-hand side of the machine. Fig. 4 is an enlarged vertical section taken at the line .fr of Fig. 2. Fig. 5 is a horizontal section taken at the line w w of Fig. 2. Fig. 6 is a central horizontal section through the spool and case and showing the spool-shaft in elevation.

In the several views the same part is designated bythe same numeral of reference.

1 designates the frame-Work of a Remington typewriter, and 2 the top plate thereof.

At the rear of the machine is a transverse shaft 3, which rotates in suitable bearings 4 and which, as usual, is connected to the carriage-driving mechanism of the machine. (Not shown herein, however.) At the righthand end of said shaft is a beveled pinion 5, adapted to engage with a beveled gear 6 on a ribbon-spool shaft 7, mounted to turn in suitable bearings 8. Near the other end of said shaft is arranged another beveled pinion 9, adapted to engage with a beveled gear 10 on a ribbon-spool shaft 11, mounted in suitable bearings 12 at the left-hand side ofthe machine. grooves 13 and 14, adapted each to receive a pivoted latch 15 to hold said shaft against longitudinal movement accidentally and to maintain either set of beveled gears in engagement as desired.

At each side of the machine beneath the top plate is arranged a sliding bar 16, which is slotted out, as at 17, and supported by screws 18, passing through said slots from below and entering threaded holes in the top plate. The slide 16 at the left-hand side of the machine is provided with a ribbon-support and ribbon-spool carrier 19, composed of wire and so bent as to embrace the ends or heads of a ribbon-spool 2O on the shaft 11 and to extend above the heads of said spool to form a rest. or support for the inking-ribbon 21. The slide 16 at the right-hand side of the machine is provided with a ribbon-support 22, also formed of wire, preferably. The said slides 1G areconnected together in the usual way by a transverse rock-shaft 23, hav- The said shaft Sis provided Withtwo f IOO ing at each end a vertical rockers'wm 24, Working in a slot in the forward end of each of said slides.

The slide at the right-hand side is provided with a hand-piece or knob 25, by which both of said slides may be simultaneously moved back or forth and the ribbon connected therewith moved widthwise to provide a new or fresh surface for the type to strike against. The right-hand slide 16 is also provided with a series of notches or a rack 26 for the en-` gagement of a spring-actuated dog 27 by which said slides and the ribbon may be held against accidental movement.

The ribbon-spool at theleft-hand side of the machineis of the ordinary construction, while that at the right-hand side of the machine is made in accordance with our improve'-v ments.- The ribbon spool or bobbin 28 at the right-hand side is arra'ngedwithin a case or box having a substantially cylindrical body 29 and cylindrical 'heads 30` and 31, all of metal'. "The spool 28 is hollow or provided centrally with an opening 32'to enable the spool to 'be fitted upon the shaft 7, and the heads 30 and 3l of the box or case are provided with holes 33 in line with the central opening in the spool to permit of the case littinguponsaid shaft also, and to afford bearings for journals 35 on the'ends of the spool 28,' so that the spool may rotate freely in the heads of the case and be held in proper position within said case whendetached from the machine. The shaft 7`is formed with'a longitudinal groove, as indicated at Fig. 2, andthe spool 28 is provided with a radial pin 36,`which enters Vsaid groove so that the shaft and the spool may turn 'at all times together, While, when desired, the spool may be moved lengthwise of said shaft. The ribbon is fastened at one end'upon the spool 28 and then woundupon the same. The free end of the ribbon passes out through a slot 37, formed by two cross-pins 38 at the ends ofthe circular body portion 29. The slot 37 is just wide enough to permit the passage therethrough of the ribbon, and the free end of the ribbon isprovided with hooks 39 or other devices incapable of passing through said slot, and hence of permitting the free end of the ribbon to accidentally fall or be wound into the casing or box. The said hooks l39 are, after adjustment of the'spool upon its shaft 7, passed up over the ribbonsupport 22, (which does not embrace the spool box or case.) thence across the machine to the opposite' spool 20, and are fastened thereto or to a piece of tape secured upon said spool. The ends of the pins 38 are slightly longer than the'width ofthe body portion 29 and pass through' holes in the covers or heads 30 and 31. 'The body portion 29 is formed around its edge on each side with a series of pins orand the ribbonlsp'o'ol'20. Vvidedwith an e'ye42, which passes in between riveted to the body portion 29 after the placement in position Within of the spool 28.

In practice we preferably first' vrivet or secure one head, then put in the spool with the ribbon thereupon, passing the leading end of the ribbon edgewise laterally into the slot 37, and then putY on the other headV or cover and rivet it securely upon the body portion 29. Wh en the ribbon has thus been placed within the case or box, it cannot be removed and another ribbon substituted for it without cutingl off or filing away the heads of .the pins or studs or otherwise destroying the box and vpresenting some evidence of the box having been tampered with.

The head or cover 31A is provided with an arm 41, which is connected to the vright-hand slide 16 to enable the box and the ribbonspool 28 to move back and forth with said slide The ar1`n`41'is" pro'- two depending plates 43 on theunder sidefof the slid e 16,'having perforations 44 inline with the' perforation 42 in the arm 41.` On the urider side of the slide is also fixed a depending vsprin g 45provided with a conical or spherical' vpin 46, adapted to pass through the opening in one of the plates 43 and engage the open'- ing 42 in the arm 41 to lock or hold the same in position and effect a connection between the box or case and the right-hand'slide 16.

The eye 44 in the rearmost, plate 43 maybe dispensed with, if desired. The spherical' or conical pin 46 enables the arm 41 to be pushed into the slot or housing between the plates 43' and automaticallylocked, and A(also permits'itl to be withdrawn or unlocked therefrom without moving the spring 45 laterally by hand. The outer end of the shaft 7 terminatesvat'the dotted line 47 at Figs. 1 and 3, so as'to leave sufficient room between it and the frame of the machine for the slipping on endwise of the spool 28 and its box or casing. After the spool and boxhave been slipped upon thel shaft 7 the box is turned by hand'until the eye in the arm 41 is sprung into the'space between the two plates 43 and caught by the conical pin 46.'

In the positions of the parts at lig1 the shaft 3 by the driving mechanism ofthe ma` IOO Ilo

chine is rotated in the direction of the arrowv thereat, and the ribbon is caused'to wind upon the left-hand .spool 20, the spool 28 and the shaft 7 turning as the ribbon paysoff .from the last-mentioned spool. If the shaft 3 be moved longitudinally, so that the catch 15 may engage with the groove 14, the beveled gears 5 and 6 will be thrown into engagement and the gears 9 and 10 out of engagement, and

thereafter as the shaft 3 continues to'rotate in the same direction the shaft 7 will be turned and the ribbon wound lengthwise inthe reverse direction orback upon the'spool 28.l

`When the ribbon through usage has become worn or exhausted, a fresh or new ribbon in another box or casing may be substituted in its place, and by reason of the employment of the boxes this substitution of ribbon may be more conveniently effected and with less liability of soiling the hands than heretofore.

The box or case must be held in or on the machine against turning, so as to keep the slot 37 in proper position at all times to deliver the ribbon in the right direction, and the attachment of the box must be made either to some stationary part of the machine or to some part which has only a lateral movement-such, for instance, as the slide 16.

Instead of making the boxes or cases of metal and riveting on the head or heads, the boxes or cases may be made of wood, pasteboard, celluloid, or other material, and glued or otherwise permanently put together, so as to prevent change of ribbon without trouble and detection.

In addition to the advantages above alluded to, the employment of the boxes prevents the drying-out of the ribbons easily and the accumulation of dust thereon while the ribbons are in stock or on the machine.

What we claim as new, and desire to secure by Letters Patent, is*

l. The combination of a type-writer ribbon, a slotted case incapable of being opened without destruction, and a spool arranged within said case and incapable of being extracted without destroying said case.

2. The combination of a type-writer ribbon provided at one end with fastening devices, a slotted case incapable of being opened without destruction, and a hollow spool arranged within said case and incapable of being extracted without destroying said case, the said case being provided with open bearings and the said spool being provided at its ends with hollow journals.
