PATENT JACOB FELBEL, OF NEW YORK, N. v.

TYPE-WRITING MACHINE.

sPncIFIcATIoN forming part of Letters Patent No. 613,365, dated November 1, 189's.

Application filed November 8, 1897. Serial No. 657,755. (No model.)

To all whom it may concern.-

Be it known that I, JACOB FELBEL, a citizen of the UnitedStates, and a resident of New York city,in thecounty of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Ma chines, of which the following is a specification.

My invention relates to what is known as line-locking mechanism, or means for preventing the types from printing when the end of a predetermined line or amount of carriage travel has been reached, and has for its main object to provide an efficient and desirable mechanism of this description.

To this end my invention consists in the various features of construction and arrangement and combinations of devices hereinafter more fully described,and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a vertical central longitudinal section of a Remington N0. 2 type-writer, showing my in' vention. Fig. 2 is a rear elevation of the same with the parts in the same positions as in Fig. 1. Fig. 3 is a detail view showing in full lines the mechanism in its operative position and in dotted lines its position immediately after release. Fig. 4 is a perspective view of the mechanism in the same position as in Figs. 1 Fig. 5 is a perspective detail view of the cam and the rod upon which it is mounted. Fig. 6 is a partial plan View of the carriage, showing the operating-pins and their mode of mounting. Fig. 7 is a plan View showing a modification of parts of the mechanism shown in Figs. 1 to 6. Fig. 8 is a rear elevation of the construction shown at Fig. 7. Fig. 9 is a detail perspective view of one of the cams or actuating devices on the carriage at Fig. 7. Fig. 10 is a detail perspective view of the release-key shown at Fig. 7. Fig. 11 is a plan view of a further modification, more especially in respect to the release-key. Fig. 12 is a rear elevation of a still further modification or arrangement of the cams or actuating devices, &c. Fig. 13 is a partial plan section of the machine shown at Fig. 12, with the parts in the same position asin the last-mentioned figure. Fig. 14 is an enlarged detail of the mechanism shown at Figs. 12 and 13 in operative position. Fig. 15 is a View similar to Fig. 14, but showing the positions of the parts immediately after releasement. Fig. 16 shows a still further modification of the actuating and releasing devices. tical central longitudinal section of a machine of the Oaligraph type having my improvements applied thereto. Fig. 18 is a rear elevation of the same with the parts in the same positions. Fig. 19 is a plan section on the line 19 19 of Fig. 18. Fig. 20 is a detail view of the operating-cam. Fig. 21 is a detail view of the operating-pin and its nut.

Referring now particularly to Figs. 1 to 6, inclusive, 1 designates the paper-carriage, which may be of any desired or suitable construction and may be mounted in any desired manner so as to travel back and forth in the usual way, the movement of the carriage from right to left occurring step by step under the influence of a spring-drum or other motive power and controlled, as customary, by suitable escapement or letter-feedin g mechanism.

' 2 represents the feed-rack, connected to the paper-carriage; 3, the spring-drum by which the carriage is drawn from right to left, and 4 the spacing-dogs, adapted to properly cooperate with the feed-rack in the usual manner.

On the top plate 5 of the machine are arranged in a circular series the desired number of type-bar hangers 6, in each of which is pivoted at 7 a type-bar 8, bearing in this instance at its lower end an upper-case type.9 and a lower-case type 10. The series or set of type -bars when not in operation bear against the type basket or rest 11, which is elliptical in form and is supported from the top plate by depending arms 12. To the upper shorter crank-arm of each type bar or lever is attached one end of a connecting-rod 13, whose lower end is connected to its associated keylever 14, preferably through a turnbuckle 15 and strap or loop 16, all of which is old in the said Remington No. 2 machine. Other features of said machine are likewise shown in the drawings; but since they have no material connection with my improvements they need not be specially referred to.

I shall now deal more particularly with my invention.

Fig. 17 is a ver-- A short distance below the type basket or rest and axiallyof the type-barsystem stands, normally, a ring or wheel like device 17, preferably elliptical in configuration and preferably corresponding substantially in outline to that of the type-rest 11, but made of a smaller size. The shape of the type-rest determines the form or disposition of the lower ends of the type-bars when they are in nonworking position-that is to say, in this instance the type ends of the bars when at rest are disposed in or describe an oval or elliptical figure. For this reason in the said Remington machine the ring 17is preferably made of a shape or form corresponding to or approximating the figure or outline described by the type ends of the type-bars. Of course where the type-bars are differently disposed the device 17 would preferably be differently shaped, and if the type-bars should not extend around to a complete ellipse orin acomplete circle or othercontinuous figure it would not be necessary for the device 17 to be made continuous or as a complete elliptical device or a complete circular device, (to. Thus it will be understood that if, for example, the type-bars were arranged in a semicircle or equivalent curve, as in well-known machines, it would be necessary to make the device 17 likewise only semicircular or of a substantially similar curve.

The purpose of the device 17 is to prevent the movement of the type-bars to the printing-point or to the paper on the platen when the carriage shall have arrived at the end of its predetermined line, (which of course may be varied,) and thus prevent one letter from printing upon or over another. The said device 17 in the views under consideration is attached to the upper end of a stem 18, which may be, though not necessarily, pivoted at 19 to the inner end or longer arm of a lever 20, fulcrumed at 21 in a stand 22, attached to the framework. To the rear or shorter arm of the lever is pivotally or loosely connected, as by hooks and eyes, at 23, the lower end of an operating-rod 24, which at its upper end carries a cam-piece 25, preferably pivoted at 26 to said rod. The cam-piece comprises an inclined or cam portion 27, a flat or horizontal portion 28, and a perforated lug 29, which enters between a pair of similar lugs 30 on the uppermost end of the rod 24. The campicce is formed with a jaw 31 and the rod with a jaw 32, and in the normal position of the cam-piece these jaws are maintained in contact by the pressure of a coiled spring 33, let into a seat in the upper end of the operating-rod and bearing at its upper end on that side of the cam-piece opposite the jaw 31. The upper end of the rod is forked or bifurcated at 34 to enable the lug 35 on the campiece to descend and the jaws to open when the carriage is retracted, as will hereinafter appear.

The rod 24- is held up by a coiled spring 36, which spring on account of its angular attachment to the rod and to the top plate of the machine, as shown, also tends to draw and hold the said rod toward the right (considered from the rear of the machine) and against a stop 37, which may be formed at the end of a guide-slot 38 made in the top plate. A pin 39 on the said rod strikes against the top plate and limits the upward movement of said rod under the influence of said spring. The said operating-rod 24 near its lower end is formed with a slot 40, in which is located a pin 41, which projects rearwardly from the upper free end of an arm 42, fastened to the rear end of a rock-shaft or long pivot 43, supported in

suitable stands

44 and 45 and provided at its front end with a keylever or arm 46. As will be seen at Figs. 2, 3, and 4, the lever 20 is preferably made so that the shorter arm 47 is offset from the longer arm of said lever. This eifcct may be best produced by making the lever in three separate parts-namely, the long arm, the shorter arm, and a long laterally-arranged pivot connecting said arms together.

The ring or device 17 may be covered or surrounded exteriorly with a soft or yielding material, as felt or soft rubber 48, to protect the types, and for the purpose of guiding said device in substantially a right line during its movements wires may be employed, and these may be attached to the type-rest and so bent or shaped as to provide within the device 17 the vertical guide fingers or portions' 49.

The carriage or some part attached thereto is provided with a device or a plurality of devices for actuating the rod 24 and forcausing it to vibrate the lever 20 and move the ring or intercepting device 17 to a position where it will be in the path of the type-bars, and thus block them or obstruct their course of travel toward the printing-point. Numerous devices for this purpose may be provided not only on the paper-carriage, but on some other part of the machineas, for instance, the spring-drum or other earriagepropelling power-as will hereinafter be explained.

In Figs. 1 to 6, inclusive, the rod 24 is actuated by a pin 50, carried by the carriage. Said pin projects rearwardly from a block 51, having a set-screw 52 and adjustable lengthwise in a long slot 53, formed in a bar 54, attached by rigid integral side arms 55 to the carriage-frame, and thus made directly a part thereof. The purpose of making the pin 50 adjustable is of course to provide for actuating the type-har-intercepting ring or device 17 at any desired point or time in the forward course of travel of the carriage from right to left, and to aid the operator in adjusting said pin the bar 54 may, if desired, be graduated to correspond with the usual carriage-scales. At Fig. (3 Ihave shown two such adjustable pins 50, whereby the typebars may be automatically intercepted twice during one run of the carriage from right to left, and the mechanism is such that the typebar-intercepting means may be restored to normal position after each such action, so that the carriage may proceed and writing be done beyond both said actuating pins or devices to the full limit of carriage travel provided by the construction of the machine. Instead of having two adjustable actuators, as shown in Fig. 6, the carriage may have one adjustable and one fixed actuator, as in Fig. 7.

The actuating-pins 50 are arranged to travel in a horizontal plane which passes through the inclined or cam portion 27 of the piece or head 25, so that in the step-by-step movement of the carriage from right to left when said pin arrives at the said cam portion 27 the cam-piece and the rod 24, of'which it forms a part, are forced or wedged down slightly by the pressure of said pin and until the latter comes upon the plane or table portion 28 of the cam-piece, as shown at Fig. 3. By thus depressing the operating-rod 24: the le-' ver 20 is actuated and the intercepting-ring is pushed up into the path of vibration of the series of type-bars, as shown in dotted lines at Fig. 1, so that none of said type-bars can be sufficiently vibrated to reach the printingpoint. As I have shown the relative arrangement of the intercepting-ring and thetypebars only a very slight movement of the type bars may be obtained when the ring is in intercepting position; but if the ring were smaller at greater movement of the type-bars might be had. 1 preferably construct the ring of a size or so arrange it that the typebars may have some movement at least before encountering the intercepting device, for by so doing a yielding or more springy action is provided in case a key should be struck after the intercepting device is in operative position, and which action is desirable because it relieves the type-movement and the escapement-movement of strain and also produces less of a shock to or reaction upon the muscles and nerves of the operator than is the case where the line-locking device comes suddenly into rigid and unyielding action.

If while the intercepting device is in working position (Fig. 1 in dotted lines and Fig. 3 in full lines) it be desired to restore the said device to its normal or non-working position in order to enable one or more letters to be added to the line, the operator may depress the key-lever 46, thus rocking the shaft 43 and vibrating the arm 42 toward the left, (viewed from the back of the machine,) and by reason of the connection between the crank-arm 42 and the rod 24 the latter is forced over toward the left and the cam-piece is swung away from and out of operative relation to the pin 50 on the carriage, and as soon as this is accomplished the spring 36 operates to draw up the said rod and through the lever mechanism pull down the intercepting-ring, thus bringing these parts to the dotted-line positions shown at Fig. 3 and with the cam-piece on the left-hand side of the pin 50, thus removing the interceptingring and enabling the Writing to he proceeded with. If there should be a second actuatingpin, this would of course act upon the typebar-intercepting mechanism in the same manner as that above described, and if it should be desired to again release the same or throw it back into normal position the release-key 46 could be operated as before. After the release has been effected and the operatingrod has been thereby thrown to the left, as shown in Fig. 3, or to the non-operative side of the pin 50, it will be brought to its normal vertical position against the stop 37 (shown at Fig. 2) by the spring 36 as soon as the carriage has advanced farenough to permit this movement to occur. On the return movement of the carriage for the beginning of a new line the said pin 50 will strike the vertical face or side 56 of the cam-piece and cause it to rock down independently about its pivot 26, so as to enable the said pin 50 to pass by the said cam-piece, and as soon as this has taken place the spring 33 will restore the cam-piece to its normal position with the stop-

jaws

31 and 32 in contact.

The type-bar-interceptin g mechanism is not constructed to also stop the carriage travel-- that is to say, when the parts are in the positions shown in full lines at Fig. 3 the carriage travel may be proceeded with by actuating the usual space-key and also by operating the usual carriage-release key which disengages the escapement mechanism. In prior constructions where the line-locking mechanism is arranged so as to act, upon somepart of the escapement mechanism the carriage travel is simultaneously arrested and the line-locking mechanism must be released or thrown out of engagement before even the space-keys can be operated to step the carriage down, and if the carriage-release key should be actuated w thout first disengaging the line-locking mechanism or simultaneously disengaging it the strap or band which connects the spring-drum with the carriage would form a loop and become disarranged, if not broken, on account of the locked condition of the escapement mechanism and the inability of the spring-drum to rewind during the run-down of the carriage. Of course in my construction there can be no feeding of the carriage through the. agency of the type-bar key-levers while the intercepting-ring is in operative position. But while I prefer not to positively stop the carriage travel, as above explained, this may be easily accomplished, it will be seen, by provid-- ,Referring now to Figs. 7, 8, 9, and 10, the

modification therein shown concerns particularly the parts carried by the carriage. In

these views will be found actuating .devices for the rod 24 of different detail construction.

The bar upon which theyare' mounted is pivotally connected to the carriage, and instead of providing a releasing mechanism at or in the vicinity of the keyboard,as in Fig. 1, the said releasing mechanism will be found connected with the paper-carriage.

The slotted bar 54 is connected to the paper-carriage by links or pivoted

arms

59 and 60. The slotted bar 54 carries one adjustable actuating device (51 and one fixed or non-adjustable actuating device (32. These are constructed alike, excepting that the adjustable device has a set-screw (33 for clamping it in the desired position. These devices are provided each with a beveled inclined or cam face 27 and an adjacent plane horizontal portion 28, formed on the underside of the rearwardly-projecting device and which at its inner end is channeled or formed with shoulders to embrace the sides of the slotted bar 54, as shown more particularly at Fig. 9. The shank of the set-screw 63 for the adjustable device passes through the slot in the bar 54 and enters a tapped hole in the bottom plate of said device, and the collar below the head of the screw bears on the top of the slotted bar and serves to hold the device firmly in its adjusted position, the flanges or shoulders preventing any side play or swivel action.

As shown at Fig. 8, the pivoted cam-piece at the upper end of the operating-rod 24isreplaced by a plane pivoted piece 35, havinga rounded corner 64 whereit is engaged by the cam-face 27 on the slotted bar on the earriage and a plane horizontal top portion 65 for engaging with the plane portion 28 of the said device. A spiral spring 66 is attached at one end to the link 60 and at its other end to the carriage, and said spring acts to return the slotted bar toward the left (viewed from the back of the machine) and to hold it there normally. The link 60 is provided with a projection 67, which engages a pin 68 on the carriage and stops the movement of the slotted bar toward the left under the influence of said spring. A carriage-release key somewhat similar to that usually provided in the Remington No. 2 machine for raising the feed-rack is also connected to the slotted bar, as well as to said feed-rack, whereby the escapement mechanism and the type-bar-intercepting mechanism are both simultaneously released. The said releasekey consists of a rock-shaft 69, mounted in bearings 70 in the carriage-frame, a key or handpiece 71, a laterally-extending arm 72, and an upwardly-bent arm 73, to which latter is pivoted one end of a link 74, whose opposite inner end is pivotally connected to the link 60. The lateral arm '72 overhangs an arm 75, extending forwardly from the rackbar. By this construction and arrangement when the finger-piece 71 is depressed the shaft 69 is rocked in its bearings, the arms 72 cause the rack-bar to swing upwardly out of engagement with the dogs, and at the same time the vertical arm 73 of the release-key swings outwardly and, pulling upon the link 74, causes it to pull the link 60 and the slotted bar 54 and the link 59 in the same direction against the tension of the spring 66. Thus it will be seen that when the cam 27 has caused the depression of the 'operating-rod 24 and the elevation of the intercepting-ring the type-bars may be freed for further action, so as to add one or more letters to the line, by causing the actuator 61 on the carriage to step over or pass by the said operating-rod by a forward movement of said actuator instead of by a backward movement of said rod, as in the previous views, and this forward movement of said actuator, it will be seen, is effected by a key on the carriage instead of by a key at the keyboard. On the return movement of the carriage after such stepping-over action the rear vertical portion 76 of the actuator 61 strikes the front vertical portion of the lug 35 and causes this device to rock on its pivot, as before, to enable the said actuator to get back again on the opposite side of the operating-rod, so as to be in a position to actuate it again on the next advance of the carriage.

Referring now to Fig. 11, the construction there shown is substantially the same as that shown at Fig. 7, with the exception that I have introduced a release-key independently of the rack-release key, thus permittinga release of the type-bars without aifecting the feed-rack. In this construction the releaselever 77 is pivoted at 78 between its ends to the carriage-frame and at its rear end is coupled to the swinging or pivoted actuatorcarrying frame, composed of the two links and the supporting-bar, by a link or coupler 74, as in Fig. 7. The mode of operation of the devices is the same in this instance as in that described with reference to Figs. 7 to 10, inclusive, excepting that the releasekey affects only the devices which cooperate with the t-ype-bar-thwarting mechanism.

Referring now to Figs. 12, 13, 14, and 15, a further modification will be found there exhibited. The actuating-pin 50 is placed on a circularly-slotted disk 79, carried by the carriage-feed spring-drum, instead of being on the carriage itself, as in Figs. 1 to 6. This pin is adjustable in said slotted disk for acting upon the mechanism at different points in the rotation of the spring-drum and in the course of travel of the carriage, the pin being combined with a screw and nut, as before, so as to enable it to be firmly set in the desired position. The obstructing ring or device 17 is connected by the stem 18 to the lever 20, pivoted at 21, and to the shorter arm 47 of said lever is pivotally mounted the operating-rod 24, in this instance made considerably shorter in length and of plate-like form. It, however, corresponds substantially in construction and mode of operation with the rod 24 shown in the previous views. The said operating rod or plate 24 is guided by an arm or bracket 80 at its lower end and is connected by a spring 36 to the framework, which spring operates in substantially the manner hereinbefore set forth. Pivotally mounted at 26 on the device 24is a cam-piece 25, having an inclined portion 27 and a horizontal portion 28,

as before, but otherwise slightly different in construction. In this instance the cam-piece is provided with a projection 81,which normally presses against a stop-pin 82 on the device 24 and limits the pivotal action of the cam-piece under the influence of its individual spring 33, and the said cam-piece is also provided with a downwardly-extending arm 83, which is pivotally attached by a screw to the slotted end of a link 84, which is pivoted at 85 to an upright lever 86, fulcrumed at 87 in a bracket 88, and provided with an individual spring 89. The upper end of the lever 86 is loosely connected to the rear end of a release-key lever 90, which when its key or finger portion 91 is pressed toward the framework of the machine operates through the lever 86 to force the link 84 inwardly, and by reason of its connection to the crank-arm 83 of the cam-piece the latter is tilted or vibrated toward the right, (viewed from the back of the machine,) as shown at Fig. 15, and is thereby released from the actuating-pin 50 and when so released enables the operating rod or plate 24 to rise and cause the intercepting-rin g 17 to descend out of the path of the type-bars.

At Fig. 12 the parts are in their normal positions and the pin 50 is approaching the campiece. having forced down the cam-piece and the rod 24 and lifted the lever 20, so as to move the intercepting-ring into the path of the type-bars. If, now, it should be desired to write beyond this point, the release-key is operated as before explained and the cam-piece is thrown back to the position shown at Fig. 15. On the return movement of the carriage the square face of the pin, acting upon the square face of the cam-piece, will also tip the cam-piece back, as shown at Fig. 15, so as to permit said pin to pass by and again get behind the cam-piece in order to operate the parts anew at the predetermined end of the next line of writing. The lever 20 may be provided with a projection, as 92, adapted to a pin 93 on a bracket 94, so as to serve as a supporting means for the weight of the lever and the intercepting-ring when in their normal positions and also as a stop for these devices and the vertically-arranged rod or plate 24, and whereby the latter is held always at the proper elevation to enable its cam-piece to cooperate with the pin or device which actuates it. The stem of the ring, and hence the ring itself, may be guided by an eye 95, formed in the upper end of an arm or bracket 96, attached to the bed-plate or frame.

Referring to Fig. 16, a still further modification of means for depressing the operatingrod 24 is shown. In this case the cam-piece, constructed similarly to that shown in Figs. 12 to 15 and provided with an individual spring,

At Fig. 14 the said pin is shown as is pi voted upon a lever 97, fulcrumed at 98 on a stand or bracket 99 on the frame. An ad j ustable pin, as 50, on the carriage is adapted to cooperate with said cam piece to depress said" lever, and the depression thereof in turn effects a depression of the operating-rod 24, connected to the intercepting-ring, as in the previous instances. The free end of said lever is provided with an inclined portion, thus forming a notch or recess 100 at this locality, a horizontal portion 101, and a hook or projection 102. Normally the horizontal portion 101 rests on top of the upper end of the rod 24. After the cam-piece and lever have been pressed down by the pin and the rod 24 has been depressed the latter may be released, if desired, so as to release the intercepting-ring and enable further printing to be done on the line, and this release may be efiected by a key such as shown in the first form, Figs. 1 to 4. When the rod 24 is thrown to the left (considered from the back of the machine) while the lever 97 is held down by the pin, the rod rises independently into the notch under the action of its spring 36 and the intercepting-ring is brought down out of the way of the type-bar, thus leaving the latter free to be operated and additional letters to be printed upon the line. On the return movement of the carriage the cam piece is adapted to vibrate independently, as before, to allow the pin to pass by. lThe cam-piece is provided with an inclined portion 27 anda horizontal or flat portion 28. It is also provided with a projection 81, which normally presses against a stop-pin 82 on the lever 97 and limits the pivotal action of the cam-piece under the influence of its individual spring 33, which is attached at. one end to a lug or projection on said cam-piece and at its opposite end to a pin on the lever 97.l

Referring now to Figs. 17, 18, 19, 20, and 21, the invention is there shown as applied to that description of writing-machines known as the Oaligraph, and which is one where the type-bars carry only one type instead of two, as in the Remington machine.

The construction and mode of operation of the mechanism are substantially similar to those shown at Figs. 1 to 6. In this case, how- --ever,theactuating-pin 50 (which,like the other actuators,travels only when the carriage travels) is adj ustably mounted in a curved or arc shaped slot 103, formed on or carried by the carriage-driving arm 104, which, by the link 105, is connected to the carriage and which arm is attached to a spring-actuating drivingshaft 106 beneath the key-levers, as customary in the Caligraph machine. The operating rod 24 has at its upper portion a cam-piece, as

in Figs. 1 to 6, and to the uppermost portion of said rod is connected a spring, as 36, which acts in the same manner as the previously-referred-to spring 36. The lower end of the rod 24 is pivotally connected to the rear shorter arm of the lever 20, which at its forward end supports the stem 18 of the intercepting-ring.

\Vhen the pin 50 on the arm 10d strikes the inclined face of the cam-piece, the rod is l'orced downwardly and the ring upwardly into the paths of travel of the type-bars, thus preventingthem from moving to the printingpoint, as before. hen itmay be desired to restore the intercepting'ring to its normal position, so as to permit the addition of one or more letters to the line, a release-key mechanism connected to said rod may be operated to produce this result. The said mechanism in this instance comprises a link 107, pivotally connected at its inner end to the rod 24: and pivotally connected at its outer end to the upright arm 108 of a bell-crank lever comprising said arm, a long pivot or rockshaft 100, and a laterally-extended arm 110, to which is pivotally attached the lower end of a spring-pressed stem 111, having at its uppermost end a key or button to receive the pressure of the finger. Vhen this keyis depressed, the rod 2i is pulled over toward the left, (viewed from the back of the machine,) and the cam-piece thereon is thereby disengaged from its actuating-pin, whereupon the intercepting-ring is restored to its normal position, while at the same time the cam-piece is carried to a non-working position relatively to its actuating-pin, and the key-levers may then be operated to produce additional printing on the line. On the return movement of the carriage, as the driving-arm lOi vibrates in the opposite direction, the pin thereon strikes the cam-piece on the side opposite the inclined portion, vibrates it independently on its pivot, and then passes by it, as previously explained, after which the said cam-piece is automatically restored to its normal position by means of its individual spring. I have shown two actuating-pins on the driving-arm lOl, both of which are adjustable in the slot thereof, so as to cause the obstruction or interception of the type-bars twice, if desired, during a single vibration of the driving-arm from left to right, (considered from the back of the machine.)

In all forms of my invention it will be seen that the device for preventing the type-bars from printing is one which is of such size and shape as to cover, include, or embrace all of the type-bars of the machine and is so situated as that normally it is out of the paths of travel of all of said type-bars, but when actuated is moved directly into the paths of travel of said type-bars, so as to thereby positively obstruct or intercept them. It will also be seen that in all forms of my invention some means are provided for restoring the intercepting device to its normal non-working position after the type-bars have been once obstructed, so as to permit printing of additional characters on the line.
