`To all whom it may concern:

Be it known that I, HIRAM JOSEPH HALLE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Type -Writing Machine, of which the fol-` lowing `is a specication.

`'This invention relates to type-writing machines, and has special reference to an illurnnating attachment designed to illuminate the work-sheet for the purpose of facilitating i the inspection of the work.

It frequently happens, particularly in large establishments, that type-writing machines are locatedat points whereitis impossible to secure sufficient light; and my invention therefore has for its object to provide the 4machine with an electric light, so located that the work will be illuminated either continuously or intermittently, according to the.

desire ofthe individual operator.. Y

` To the accomplishment of this objectthe invention comprehends the attachment of a small electric light at a convenient point upon theframe structure and in the provision of circuit-'closing devices arranged to permit the circuit to be closed through the lamp continuously if a constant light 'is desired or intermittently if it is desired to illuminate the Work at intervals only-as,

printing-point to reveal the writing.

Certain other objects subordinate to those enumerated and various novel featuresof lconstruction and arrangement will appear during the course of the following description of that form` of my invention which for the purpose of this disclosure is illustrated in the accompanying drawings and succinctly deined in the appended claims.

In said drawings, Figure; l is a perspective `view of a Fisher type-writing machine equipped-.with mylightingattachment. Fig. 2`is a sectional elevation iof the same. Fig. `3 is a bottom plan'view, partly in section, of a portion of the traveling carriage, illustrating the manner in which the attachment is mounted thereon. Fig. 4 is a detail view of the lamp and its bracket. Fig. 5 is a detail for instance, at Such times as the ribbon may be shifted lat` erally from the perspective View of the contact-armcarried by the lamp, and Fig. 6 is a similar View of the movable contact-arm and the bracket for securing thesame to the ribbon-shift shaft.

Like characters of reference are employed to designate corresponding parts throughout the views.

Vhile the invention broad aspect the equipment of a type-writing machine of any characterwitha lighting or illuminating device, the attachment illustrated in the accompanying drawings is particularly designed for the equipment of what is known in the art as a Fisher7 type-writcontemplates in its "ing machine, to which it is shown applied.

The Fisher type-writer includes iu its organization what is known as the machine-frame 1, designed `to travel longitudinally over the flat platen (not illustrated) and slidably supporting a carriage 2, movable transversely of the platen. This carriage supports the printing mechanism, including the keys 3, operatively connected to a series of type-bars 4, mounted upon a supporting-ringofsegmental form sustained at the lower ends of vertical bars or hangers, twoof which (indicated by 6 and 7) are pendent fromthe carriage proper adjacent to its front edge, as indicated in Fig. l. Thesebars or hangers 6 and7 are located at the ends of the segmental type-bar-supporting ring 5, and as the type-bars strike downwardly toward the axis of the type-ring the printing-point is in full view of the operator. During the printing operation, however, the line being Written is obscured by the ribbon 8, which extends under the typering from the opposite sides of the carriage, where its ends are wound upon the ribbonspools 9 and 10, shiftably mounted upon the spool-shafts 11, journaled in shaft-hangers 12, as shown. The ribbon is fed longitudinally, in a manner well understood in the art, by the rotation of the ribbon-spools; but as the ribbon-feeding mechanism constitutes no part of the present invention ithas not been fully illustrated and Aneed not be described.` f

In the present embodiment of the invention provision has been madefor closing the circuit through an electric lamp, constitut- ICO ing the primary element of the attachment, Whenever the ribbon is shifted laterally to expose the writing,and the ribbon-shift mechanism, although no part of my present in-v vention, except as it enters into a novel combination, may therefore be described. Associated with each of the ribbon-spools so`- as to be shiftable therewith are ribbon-framesupporting brackets 13, connected to a ribbon guiding and supporting frame 14, designed to properly guide the ribbon as it is fed from one spool to another and to maintain the ribbon in proper position as it is shifted laterally. The ribbon-shift mechanism-that is to say, the mechanism by means of which the operator shifts the ribbon laterally from the printing-pointwhen it is desired to inspect the writingincludes a ribbon-shift key 15, formed at one end of a ribbon-shift lever 16, secured to the end of a rock-shaft 17 and having its lower extremity forked, as indicated at 18, for engagement with a stud 19, projecting from the adjacent bracket 13. Ordinarily the ribbon occupies a position opposite the printing-point and is yeldingly retained in such position by a spring I2O, coiled upon the shaft 17 and having its opposite ends engagedv by a set-collar 21, secured to the shaft, and a post 22, secured to the bottom of the carriage-casing. (See Figs. 2 vand 3.) It will be noted that upon the depression of the ribbon-shift key 15 the ribbon, together with its frame and spools, will be laterally shifted a sufficient distance to entirely displace the ribbon from the printing-point, and as the front of the carriage is open (see Fig. l) this lshifting of the ribbon will reveal the writing for the inspection of the operator. Upon the release ofthe key the spring 20 will automatically return the ribbon to its initial position.

The structure embraced in the foregoing description is all that need be described in order that the relation of the lighting attachment to the machine may be fully comprehended, and the construction and arrangement of the attachment proper will now be considered.

The lamp (indicated by 23) is preferably whatis known as an incandescent electric lamp of small size and is located in the present instance im mediatel y below the carriagecasing, adjacent to the front edge thereof, and directly above the printing-point. This location of thelamp is desirable for the reason that while it' enables the writing to be properly illuminated the lamp is more lor less obscured from the operator by the carriage. The lamp 23 is retained, as usual, by a lamp holder or socket 2 4, to which latter I have attached a lamp-bracket 25. This bracket is bifurcated for the reception of the hanger or upright bar 7, adjacent to the upper end of which it is secured. It will of course be understood that the particular manner of attaching the lamp to the machine structure may be varied as occasion may require; but in the illustrated structure the bifurcations 26 and 27 of the bracket 25 are extended somewhat beyond the hanger 7 for the reception of a draw-bolt 28,

by means of which the bifurcations are drawn up to securely clamp the lamp-bracket to the hanger. It will be noted that by locating the lamp as stated it will be disposed closely adjacent to and parallel with the ribbon-shift shaft 17. This is particularly desirable for thereason that a circuit-closing device for the lamp-circuit may thus be operated by the movement of the shaft to close the circuit through the lamp whenever the ribbon-shift mechanism is operated to move the ribbon away from the printing-point.

To one terminal plate 29 of the lamp is adjustably attached, by means of a screw 30, an angular contact-arm 31, one end 32 of which extends horizontally and has an upturned or deflected end 33 located adjacent to the ribbon-shift shaft 17. (See Figs. 2 and 3.) A second contact-arm 34 is adjustably secured to the ribbon-shift shaft 17-as, for instance, by means of an attaching-bracket 35,'secured inplace by a draw-bolt 36. The arm 34 is disposed substantially parallel with the shaft, slightly to one side thereof, and is designed to contact with the end 33 of the contact-arm 31 when the ribbon-shift shaft 17 is rocked by the depression ofthe ribbon-shift key 15 when the ribbon is shifted laterally to expose the Writing. These contact-arms '3l and 34 constitute a circuit-closing device for the lamp. y

A lead-wire a is connected to the contactarm 34 (see Fig. 3) and to a binding-post 37, mounted on a switch-block 38, preferably mounted upon one end of the carriage-casing adjacent toits rear edge. Asecond lead-wire b is connected to the second terminal plate 39 of the lamp and to a second binding-post 40 on the switch-block, circuit-wires a: and y being extended from the binding-posts to a suitable source of electrical energy. In the accompanying drawings I have indicated a battery B in the lamp-circuit; but obviously the circuit-wires of the lighting and power systems installed intbuildings might be attached to the binding-posts with equal facility.

ICO

IIO

It will now be observed that whenever the the ribbon will be shifted away from the print- 1 ing-point, and vthe shaft 17 will be rocked for the purpose of closing the lamp-circuit by bringing the arm 34 into contact with the arm 31, and the lamp will thus be automatically lighted whenever the ribbon-shift mechanism is operated. The lamp-circuit when closed in the manner stated may be traced 'as follows: from the binding-post 37 through the wire a to the contact-arm 34, thence to the arm 31, to the lamp-terminal 29, through the lamp to the terminal 39, through the wire b to the binding-post 40, and thence through the circuit-wires and battery to the firstnamed binding-post 37. Upon the release of the ribbon-shift key the ribbon will be re- 35 i ing-post 37, upon which is mounted aswingstored to its normal position by the spring 20, and the shaft 17, beingrocked in the reverse direction, willmove the contact-arm 34 away from the arm 3l to break-thc lamp-circuit, and thus automatically extinguish the light after the illuminated work has been inspected.

The arrangement described is considered `preferable when the attachment is employed in connection with a Fisher` type-writing machine; but it is by no means essential that the ribbon-shift mechanism be utilized for the purpose of effecting the opening and clos-` ing of the lamp-circuit; The desired end may `be attained byarranging a circuit-closing deattachment merely as a device for illuminating the writing Whenever the latter is exposed by the shifting of the ribbon; but'it may be desirable under some circumstances to employ the light continuously, and this may be done Without annoyance to the operator, for

the reasouthat the lamp is so located, as heretofore stated, that the eyes of the operator will be shielded from the bright light. I

have therefore connected a third lead-wire c 'to the contact-arm 31 and to a contact-plate 41, mounted in the switch-block 38. The contact-plate 41 is located to one side of the binding switch-arm 42, designed to be swung into and out of contact with the plate 41. If the operator desires a constant light, it is simply necessary to swing the switch-arm 42 into contact with the plate 41, thus closing the circuit through the lamp as follows: from the binding-post 37 through the arm 42, contactplate 41, Wire c, arm 3l,.lampterminal 29,

`45 thence through the lamp to the terminal 39, thence through the Wire ZJ to the binding-post` 40,"and thence through the circuit-wires and battery back to the binding-post 37.

j From the foregoing my lighting attachment will be seen to include an electric lamp carried by the machine structure and a pair of circuit-closing devices, one of which is rnanually operated for 4the purpose of securing a Vcontinuous or constantlight and the other ofwhich is automatically operated `intermittently by a moving part of the machine, preferably an element of the' ribbon-shift mechanism, to effect the lighting of the lamp at l such times only as the Writing may be revealed to the operator by the shifting of the ribbon away from the printing-point. I Wish it to be distinctly understood, however, that While the present embodiment of the invention is thought at this time to be preferable the invention in its broader aspect comprehendsthe equipment of a type-Writing machine with an electric light or other illuminating device, irrespective of its construction and arrangement, and I therefore reserve the right to effect such changes, modifications, and variations of the illustrated structure as may be fairly comprehended within the scope of the protection prayed. For instance, if applied to cylindrical-platen machines the lamp should be attached to a fixed part of the frame at a suitable point to throw light on the work and in such relation to the carriage that when the same is raised to view the work the light is turned on by the mere act of raising the carriage, and I desire it understood that I consider this modification to come within the purview of my invention.
