'rvrnwnrrme Specification of Letters Patent.

Patented May 4;, 1909'.

To all whom it may concern:

Be it known that l, JACOB FELBEL, citizen of the United States, and resident of the borough of Manhattan c-ity-of New York,v in the county of New York and State of. New York, have invented. certain new and useful Improvements in Typqe vvriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to stop devices for arresting the platen at predetermined points in its rotation, the mechanism being devised more especially for use in billing and condensed record work. V

The main object of the invention is to provide simple and ellicient means of the character specified.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter more fully described. and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is an end elevation, partly in section, on an enlarged scale of part of a 'typ'ewriting niachine embodying my invention. Fig. 2 is an enlarged plan view of the same, the view including parts which are sectioned away in Fig. 1. Fig. 3 is an enlarged detail front elevation, partly in section. Fig. 4 is an enlarged detail perspective view of one of the clutch members. Fig. 5 is an enlarged de tail perspective view of the other clutch member together with the rotative stop carrier which is formed: as a art of said clutch member. Fig. 6 is an e arged detail fragmentary sectional view taken through the clutch members and the sprocket wheel connected therewith.

In the present instance I have shown my invention embodied in the Monarch type.

writing machine to which it may be readily applied without materially modifying the regular structure of said machine.

The top plate 1 supports standards 2 to which fiXed guide ra' s 3 are secured by screws 4. The rails 3- are oppositelygroo-ved and contain anti-friction balls or rollers 5 which also run in opposite grooves fi formed ing forwardly from the rear bar 7 are-side or end bars 8, these seve-ral'bars forming in the main the platen frame or carriage. A cylindrical rotative platen 9 is secured to a platen shaft 1&0. bya set screw 11 which enters a threaded hole in. the hub of the right-hand platen head 12 andibears against the platenshaft. The platen shatt extends through and is journaled in bearing openings the end plates 8- and isprovided at its ends. with finger wheels1 3 and 14 in the usual manner. The left-hand platen head is formed with line spacing ratchet teeth 15 with which a spring-pressed roller detent 16 cooperates. A line spacing pawl 17 isv pivoted to and carried by arm 18 and co-acts with the line s acing wheel under the control of a finger piece 19 to efiec-t step-by-step line spacing movements of the platen. The right-hand end plate 8 of the carriage is formed with an upwardly extending arm. 20 provided with a finger piece 21 by which the carriage may be moved to-the right and by which it may be controlled when released from its spring drum for rapid movement toward the left. The parts thus .far described are of the usual Monarch construction and further description thereof is deemed unnecessary; 7

To the righthand end oi the platen shatt 10, where it extends beyond the right-hand end late 8- is secured a band or sprocket whee: 22.. Thisv sprocket wheel may beheld to the shaft by a set screw 23 passing through a threaded opening in the hubof the wheel 22 and bearing against the platen shaft. The sprocket wheel 22 is thus operatively and. rigidly connected with the p aten to rotate therewith and constitutes a driving wheel as will hereinafter more clearly appear. A second band or sprocket wheel 24 is provided to. cooperate with the wheel 22. A long shouldered screw or bolt 25 is threaded intoa tapped hole in the righthand end plate 8- of the carriage, as indicated at 26.

27 is a clutch member comprising a sleeve 28 and a cup or housing 29, the sleeve and bottom of the cup being-fitted to turn on the bolti25-. The sprocket wheel 24 is secured v by a drive fit or otherwise upon said sleeve.

The cup portion of the clutch member is formed or provided with a series of teeth 30,.

preferably equalin number to the number of ratchet teeth 15 on the platen head. The teeth 30 .ra'diateoutwardly from the cup and are adapted to coijperate with a single tooth 31 formed or provided interiorly of a second cup 32 forming part of a companion clutch member 33, likewise mounted to rotate on the bolt 25. The clutch member 33 is provided with a sleeve 34. The clutch 27 is prevented from moving axially of the bolt by the hub of the sprocket wheel 24 and by a Washer 36, interposed between the end plate 8 and the sleeve 28 and hub of the sprocket wheel The clutch member 33 is formed or pro Vided with a circular groove 37 to receive the rear forked end 33 of a clutch lever 39, which is pivotally supported at 40 upon a bracket 41 secured by screws 42 to the under side of the end bar 8, The fork 33 is provided at its ends with inwardly projecting studs 43 arranged on opposite sides of the axis of the bolt and vertically one under the other. The clutch 33 is provided with a stop carrier 44, in the form of a circular disk, which as shown is formed integral with the clutch member, the said disk or carrier 44 in the present instance constituting the outer wall of the groove 37 in which the fork of the clutch lever is arranged to operate.

The stop carrier 44 is perforated circularly near its perimeter with equi-distant holes 45, preferably equal in number to the number of ratchet teeth'on the platen head. A. pin 46 on an arm 47 is adapted to enter any of the holes 45 according to adjustment of the arm, which is provided with a hub 48 which takes a bearin on the barrel of the bolt 25. The arm 47 has a tension toward the perforated disk and hence a tendency to keep the pin 46 seated in the selected hole. The arm is pro- Vided with a finger piece 49 by which the arm may be flexed or moved to disengage the pin from one hole and rengage it in another hole after a rotary movemento'f said arm.

The bolt is headed at 50 and at this portion is provided with a light spring 51 that presses at one end against the head and at its opposite end against the hub 48 of the arm. This arm is formed with an extension or projection 52 that constitutes a stop, adapted to contact with one side of an arm 53 projecting outwardly from the end bar 3. Another stop 54, preferably made integral with the perforated disk or carrier 44 is also adapted to contact with said arm 53, but on the opposite side thereof from that which the stop 52 contactswith. The two sprocket wheels 22 and 24 are connected together by an endless chain, band or belt 55.

The outer end of the clutch lever is fashioned into'a handle or finger piece 56 and said lever is held in either one or two positions by an arm 57 secured to the side bar 8 and having two notches or depressions 58, the outer end of which is engaged by the lever in the positions of the parts shown at Fig. 2. The said arm is preferably resilient,

so that the lever may snap from one notch to the other and be held or locked where set by the springiness and grip of the arm 57.

l ieferring more particularl to Figs. 1, '3, 3 and (3 the clutch members are in engagement and the mechanism is in working condition. If new the platen be rotated the sprocket wheel 22, turning therewith, will drive the chain or band 55 and cause the wheel 24 to be driven, and since this wheel is fast on one of the clutch members and. the clutch members are in engagement the stop carrier =l-l will be rotated simultaneously and carry with it the engaged stop if the platen be rotated in. the direction of the arrow (6 at Fig. 1 the stop carrier will be caused. to turn in the same direction as indicated by the arrow 1') and hence the stops 52 and 5-4 will travel therewith in the same direction or in the direction of the hands of a clock. in rotating the platen. in the direction of the arrow a the paper will be fed forwardly toward the printing point a? but the platen. will be arrested when the stop 52 arrives at the rear, lower side of the stop arm or bar 53. In order to feed the paper farther in the same direction it is necessary to swing the handle end of the clutch lever 39 inwardly toward the platen. By this operation the rear forked end of the clutch lever will move the. c ntch member 33 outwardly or toward the right. The rightward movement of the clutch member 33 forces the stop carrier arm 47 in the same direction, along the bolt, and against the tension of its spring 51, which is provided more particularly to keep the arm in proper relationship to tl' e perforated dish and yet permit the shifting movement of the clutch member 33 and its connected parts out of ei'igagement with the clutch member 27. ll hen the clutch member 33 has been moved to the right as just described the tooth 31 is moved out of engagement with the teeth. 30 of the clutch member 27, thus freeing the platen from the stopping devices and eiiiabling it to be turned unlimited distances either forwardly or bacswardly by means of the hand knobs or wheels 13-; and ll or by means of the line spacing mechanism. .i'lit this time however, the chain or band and the band wheels, as well as the clutch member 27, all move when the platen rotated, these devices being pernninently connected with the platen.

In the working positions of the parts shown at Figs. 1, 2, 3 and (3 the platen. may be arrested in its backward rotation. by the engageinent of the rotary stop 54- with the fixed stop 53. The adjustable stop 52 is shown set so as to allow the platen to be rotated forwardly a distance of about 27 line spaces before arresting its movement. it will be understood of course that as the stop 52 travels around toward the stop 53 to thus arrest the platen in its forward movelll) ment, the stop 54 simultaneously travels around in the same direction and away from the fixed stop 53 and the distance which it thus travels will correspond to the distance traveled by the stop 52 until it reaches the fixed stop 53. Hence, when the platen has been rotated-backwardly su'fliciently to bring the stop 54 back into contact with the stop 53, the stop 54'; will have traveled backwardly the same distance'that' the stop 52 traveled forxvardly. Thus the forward and backward rotations of the platen are equal in extent and it will be understood that this may be varied as may be necessary by adjustment of the stop 52. This adjustment is usually determined by the depth of the printed heading of the invoice or bill sheet when the mechanism is employed for condensed record work.

In view of my prior patent No. 902,572 dated November 3rd, 108"it is not deemed necessary to describe in detail the operations of condensed billing with this mechanism.

While I have shown the perforated disk as made integral with the clutch member 33, it may of course be made separate and con nected with the clutch member. ther be understood that the direction of iovement of the sliding clutch member to engage and disengage with its companion clutch member is wholly immaterial,1 that being dependent upon the character of the clutch lever employed. In this case I have shown a clutch lever of the first order and hence when the handle end 56 ismoved outwardly it causes an engagement of the clutch members and when it is moved inwardly causes 'a disengagement thereof. When the handle is held in the inner notch of the holding arm 57 the stop mechanism is in inopera tive condition and of course at that time the platen may be rotated freely in either direction but when the handle of the clutch is seated in the outer notch the stop mechanism is connected operatively with the platen and the platen is limited in its rotative movements both forwardly and backwardly by the stoppin devices 52, 53 and 54 as before explained.

It will be noted from the foregoing that in the particular construction of mechanism herein shown and described one of the band wheels is connected to the platen shaft so as to be driven, so to speak, by the platen or at the same time the platen is rotated by either of the hand wheels or by the line spacing mechanism; that the other of the band wheels is arranged at the rear of the carriage frame and connected to the first mentioned band wheel by a flexible band which communicates the motion from the platen-driven band wheel to the said companion band wheel; that in this form of my invention the band wheels always rotate with the platenthough (as in another form of my invention,

It will fur the. subject matter of pending application Serial No. 456,236) this is not essential when considering the invention from its broadest aspect; that there is a rotary stop carrier stop carrier with the platen through the band mechanism when it is desired to arrest the platen and in uncouplmg the said carrier from the platen through the band mechanism when it is desired to have the platen rotate indefinitely without hindrance; that this construction and mode of operation considered from the broad. aspect are carried out both in the present form of my invention and in the form shown in my said pending appli cation 456,236, in which application the invention is shown in an arrangement whereby the band wheels are adapted to be clutched to and unclutched from the platen instead of always running constantly with the platen as in this case; that in the present arrangement of my invention the clutching mechanism is located at the rear of the platen frame and concentrically with the rear band wheel;

that one member of said clutch mechanism rotates always concurrently with said rear band wheel while the other member of said clutch mechanism is adapted to be maintained out of engagement with said constantly rotatable clutch member but is adapted to be thrown into engagement therewith at any desired time so as to bring about a rotative action of the stop carrier which is connected to the shiftable clutch member; that the stop carrier in this instance carries a permanently located stop and also an adjustable stop each adapted to coact with a relatively fixed stop on the framework of the carriage, but so far as the stops per 86 are concerned they may be'otherwise arranged; for example, there may be two stops on the framework and only one stop on the carrier and for further example there may be only two stops altogether, depending on whether or not it is desired to stop the rotation of the platen both forwardly and backwardly that if it be desired to rotate the platen in backward direction only then it will be necessary to use only the stops 54 and 53, while on the other hand if it be desired. to stop the platen only in its forward movement it will be necessary only to use the stops 52 and 53; that the said stops are separate from the traveling band in that they are not carried directly by the band but are carried by a part adapted to be actuated by the band; that by the operation of a clutch the r0tatory stop carrier is connected to be rotated by the chain which in turn is driven by the platen and that when said clutch is reversely operated the platen is left free to be rotated independently of said rotatory stop carrier.

Various changes may be made without departing from the spirit and scope of my invention.
