BURXIIAM O. STICKNEY, OF BROOKLYN, NElV YORK.
TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 557,711, dated April '7, 1896.
Application filed July 28,1892. Serial No. 441,464. (No model.)
To all wit-Ont it may concern:
Be it known that I BURNHmI C. STIOKNEY, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.
My invention relates more particularly to that class of type-writing machines in which there is employed, in connection with the type mechanism,tlie paper-carriage,and its escapement or feed mechanism, a tripping means or detaching device arranged at some point between the finger-piece or key and the type, by which both the type and feed mechanisms are released after the initial depression of the finger-piece or key, so that both may return to their normal positions independently and in advance of the finger-piece or key, or while the finger-piece or key is depressed or held down, whereby another finger-piece or key may be actuated without waiting for the removal of the finger first employed and the return of the previously-depressed finger-piece or key.
My invention has for its main objects to improve the carriage and type-actions and provide a machine of better touch and greater speed, capable also of accurate letter-spacing and the performance of speedier work; and to these main ends my invention consists in certain combinations of devices and features of construction and arrangement, all as will be hereinafter more fully described, and particularly pointed out in the appended claims.
In the accompanying drawings, Figure 1 is a plan view of a machine embodying my improvements. Fig. 2 is a central vertical section thereof. Fig. 3 is a horizontal section taken at the line m 50 of Fig. 2, omitting springs 41. Fig. 4 is a sectional or diagrammatic view showing in full and dotted lines the construction, arrangement, and the operation of the various parts comprising the type-movement and carriage-escapem ent. Fig. 5 is a sectional or diagrammatic view showing the type-bar trip as having been effected and the type as on its way to the platen. Fig. 6 is a similar view showing the trip as having been made and the type as having printed and returned to its normal position. This view also shows the universal bar as having returned to its normal position while the key-lever is held depressed. Fig. '7 is a side elevation of a keylever detached, constructed like that shown at Fig. 1. Figs. 8 and 9 are respectively side and edge views of the connecting-rod shown at Fig. 1. Fig. 10 is a plan view of the universal bar shown at Fig. 1.
In the various views the same part will be found designated by the same numeral of ref erence.
1 designates the framework of the machine, 2 the top plate or type-ring, and 3 the papercarriage. Around the top plate or type-ring are arranged, in substantially the usual manner, the type-bars 4, which are or may be mounted in hangers 5, secured adjustably upon the top plate or type-ring by set-screws 6.
The papercarriage is composed,preferably, of a front bar 7, a rear bar 8, and side bars 9 and 10. The front bar is preferably provided with a grooved antifriction-roll 11, which rides upon a supporting track or rail 12, mounted upon posts at the front portion of the top plate. The rear bar of the carriage-frame is preferably provided with two grooved wheels or rollers 13, which ride upon a hinge-andguide rail 14, mounted in end standards or brackets at the rear side of the top plate. J ournaled in the side bars of the carriageframe is a platen 16 and a pressure or feed roller 17, in conjunction with which may be used the ordinary paper-table 18.
Connected to the paper-carriage and pivoted or hinged to the hinge-and-guide rail 14 is a rack-bar frame 19 provided with a verticallya-rranged toothed feed-rack 20, with which cooperate two feed- dogs 21 and 22, mounted upon a trunnion or rocker 23, which is suitably supported in the framework. The dog 21 stands in engagement with the rack in the normal condition of the machine. The dog 2 is a loose, pivoted, or flexible dog and is adapted to be vibrated or moved over into engagement with the feed-rack to permit the letter-spacing of. the carriage. The dog 21 is thus the detaining-clog and the dog 22 the feeding-dog of the paper-carriage. To an arm 24 projecting forwardly from the trunnion or rocker is pivotally connected the upper end of a rod or link 25, which at its lower end is pivotally connected to an arm secured to the axis or pivot-rod 27 of the universal bar 28, which is connected at its ends to said axis or pivot-rod by side bars 29. Beneath the arm 26 is arranged a spring 30, which is provided to return the universal bar and its connections to their normal positions after actuation. This spring may, however, be arranged at some other locality. The universal bar extends transversely across the machine and is preferably provided with a flange 31.
To the shorter arm of each type-bar is pivotally attached the upper end of a connecting-rod 32, the lower end of which rests above the horizontal portion of the universal bar. The lower end of each connecting-rod is bifurcated and provided with a cross pin or ledge 33, which is engaged by a projection 3% depending from a lever 35, which preferably rests between the forks at the lower end of i the connecting-rod and is pivoted at 36 to the framework. At the forward end of each keylever is preferably provided a stem or fingerpiece 37, and beneath each key-lever is preferably arranged a returning-spring 3S. Formed integral with the projection 3i is a lug 39.
Referring now particularly to Figs. 1 to 10, inclusive, it will be observed that the lower ends of all of the connecting-rods are circular in shape or disk-like, and that they are all concentrated or arranged to lie in line transversely and rest above the universal bar. Transversely of the machine and above the key-levers is arranged a cross-rod l0, to which are connected the rear ends of a series of springs 41, the front ends of which are attached each to one of the connecting-rods of the type-bars, the arrangement being such that all of the springs operate to pull all of the lower ends of the connecting-rods rearwardly and against the lugs 39 on the keylevers. Thus by means of the springs and the lugs the connecting-rods are all maintained in proper working relation to the universal bar. As will be seen, the springs 41 are of different lengths, according to the rods to which they are connected, and said springs have only sufficient tension to hold the lower ends of the rods in proper working position. To the paper-carriage is connected one end of a cord or chain or belt 42, the other end of which is connected to a spring drivingdrum At Fig. 2 the parts are shown in their normal positions, and they are also shown in their normal positions in full lines at Fig. 4. In the last-mentioned figure, when the keylever is depressed to the dotted-line position shown, the connectingrod of the type-bar is carried down, by reason of the engagement of the projection 34 with the cross pin or piece 33, to the dotted-line position shown at said figure. During the descent of said connectin g-rod the type-bar is gradually elevated and the universal bar gradually depressed until they arrive at the dotted-line position shown at said figure, when the type-bar, connectingrod, and universal bar are released from the control of the key-lever.
During the descent of the universal bar the link carried thereby operates to oscillate the trunnion or spacing-rocker and move the detaining-dog forward from engagement with the rack and the spacing-dog forward into engagement with the rack. At this time the type has not quite reached the platen or the paper thereon, but strikes the same immediately thereafter, and consequently immediately after the release or trip of the key-lever and the carriage escapement. Thus the printing is effected while the spacing-dog is in engagement with the rack and after the carriage has been released to feed a new letter-space. In other words, the construction and arrangement of the carriageescapement devices are such as to produce what is known as the reverse feec This kind of feed is extremely useful in connection with a system or series of keys arranged to actuate and release a system or series of type bars or levers without removing the pressure from the keys. By the combination of the reverse-feed carriage-escapement and the type-bar trip the machine is capable'of much easier and more rapid manipulation and will do much more perfect work than one having merely a reverse-feed carriage-escapement or one having merely a key-trip.
In using the old or natural feed a strong feed-retracting spring 30 for the dog-holder would be necessary in order to have the carriage start soon enough to complete a letterspace distance before the next type strikes the paper, and such a strong spring 30 would much impair the value of the type-bar trip, because the type-bar when released would be so retracted by the back pressure exerted by this strong feed-spring that it would print very faintly, or perhaps not reach the platen at all, which would thus oblige the operator to use a heavier touch on the keys, thus greatly impairing the benefits of the trip; but in using the reverse feed the carriage is released just before the type strikes the platen, which gives it plenty of time to complete its letter-space distance. Thus a light carriage-spring can be used, and the time such light spring occupies in overcoming the inertia of the carriage is sufficient for the type to complete its movement to the platen before the carriage starts. Thus a quick return of the feed-dogs is not necessary to the prompt feeding of the carriage, and moreover the decreased strength of carriage spring reduces the strength required of the feed-dogs retracting-spring, which will therefore exert no perceptible retarding influence on the tripped type-bar in its motion toward the platen. At the same time by combining the reversed feed with the trip none of the known disadvantages of the reverse feed-such as blurring of the printing, irregular letter-spacin g,
and the necessity of the operator acquiring a smart upstroke of the fingerare experienced.
At Fig. 5 the parts are shown in full lines in the positions in which they are shown in dotted lines at Fig. &, and from this view it will be clearly seen that the key-lever has just released the connecting-rod and that the type-bar is approaching the platen. At the moment the release is efi'ected the type-bar, as has been said, has not completed its stroke, but does so by inertia immediately after releasement and just before the inertia of the carriage is overcome and it starts to travel a letter-space distance.
The trip or release, it will be observed, is effected during the downward movement of the key-lever and may be timed or arranged to occur at any desired position of the downward stroke of said key-lever. Vhen the key-lever is depressed, it swings or vibrates about its pivot 36 and the projection 34 is carried rearwardly in an arc of a circle. At the same time the universal bar is swung downwardly and rearwardly in the arc of a circle about the pivot-rod 27 as a center of motion by reason of the pressure thereupon of the lower end of the connecting-rod which is being forced down by the key-lever. As the key-lever and the universal bar move in diverging paths and as the lower end of the connecting-rod is confined between the keylever and the universal bar, it is forced to follow the path of travel or the arc of vibration of the universal bar, which, as will be observed at Fig. l, is nearly in a straight vertical line. lVhile the lower end of the connecting-rod is moving in this direction the projection 3% is traveling downwardly and rearwardly and leaves or slips off of the crosspin or ledge on the connecting-rod, as shown at Figs. 41 and 5. IVhen this occurs, and while the finger is yet upon the key-lever holding it down, the type prints by inertia and at once returns to its normal position by the gravity of the type-bar, assisted by the spring 30. During the descent of the typebar the connecting-rod is lifted and the universal bar and the feed-dogs are returned to their normal positions under the influence of the spring 30. The cross-pin or ledge 33 in ascending passes up into the notch 44: in front of the projection 3r. lVhen the key-lever is released, it is returned to its normal position by its spring 38 and the under side of the projection St is carried up into a position above and immediately over the cross-pin again. The projection Sat when ascending forces the connecting-rod 32 slightly forward, expanding the spring 41, and when the keylever reaches its highest position the spring ll draws the connecting-rod rearwardly again to its normal position, with the cross-pin or ledge beneath the projection 34.
It will be seen, of course, that after the depression of any key-lever and the printingof its corresponding type any other key-lever may be depressed and its corresponding type caused to print while the first actuated keylever is still held down.
In the various views there is a soft pad or cushion 4:5 to receive the key-lever at the end of its downward stroke.
So far as the broader features of my invention are concerned, I do not wish to be limited to any particular construction or arrangement of trip; nor do I wish to be limited to any particular construction or arrangement of the carriage-feeding mechanism, although I have shown herein only one form. The carriage-feeding mechanism being very old and of great variety, I have not thought it necessary to show more than one form.
It will be further understood that numerous other changes in detail, construction, and arrangement may be made without departing from the gist of myseveral improvements.
I do not claim herein, per se, either the trip, broadly, or the reverse feed, broadly; but I do seek to cover, broadly, the combination of a trip whereby a type-bar is released before printing and before removing the pressure of the finger from its actuating-key, and a feed mechanism for the paper-carriage constructed and arranged to release the paper-carriage before the type strikes the paper. I also seek to cover the same combination in connection with means for releasing the feed mechanism from the finger-key simultaneously with the releasement of the type bar, or, in other words,before the type-bar completes its printing movement, so that the said mechanism may first travel with the type-bar until the printing occurs independently of the actuating-key and then return to normal position in advance of and independently of the actuating-key. I also seek to cover the feature of detachably connecting the type-bar connecting-rod to the key-lever in a manner such that they may become automatically sepa rated upon the depression of the key-lever. I also seek to cover the feature of having the connecting-rods operate directly the universal bar of the carriage-feed mechanism, and I also seek to cover various other features of construction and arrangements of parts, as hereinbefore shown and described, and now to be more particularlyset forth in the claims.
I do not claim, broadly, in this application a construction whereby the type-bar is released from the finger-key when the type is in the vicinity of the platen and just before the printing takes place, because the novel subject-matter relating to this feature is the subject-matter covered by my application filed February 26, 1896, Serial No. 580,845.
