To all whom it may concern:

Be it known that I, THOMAS CONSENTINO, a subject of the King of Italy, (but having declared my intention of becoming a citizen of the United States,) and I, FRANK PALUMBO, a citizen of the United States, both residing in thecity and county of Philadelphia, State of Improvements in Type-IVriters, of which the following is a specification.

Our invention relates. to certain improveparticularly to a type-writer rule, the object of the invention being to provide a simple, inexpensive, and easily-manipulated device, by which any desired characters may be printed upon a sheet of material. This ob-i ject we attain as hereinafter set forth,-reference being had to the accompanying drawings, in which Figure 1 is a plan View of our improved type-writer rule, the top plate thereof being removed, sothat the mechanism may be clearly visible. Fig. 2 is a vertical sectional view on the line 2 2, Fig. 1. Fig; 3 is a view of the right-hand end of the type-writer rule. Fig. 4 is a view of the left-hand end of the type writer rule. Fig. 5 is a vertical sectional view 8 are views of certain detailed parts of our invention. 7 4

In the above'drawings, A is the foundationplate of the device, from which project ver-- tical plates E, D, and O, joined at the top by a second horizontal plate B, in addition to of which there is one at eachend oftheplate A. Two of these plates E and Dare near together at one end of the plate A, and there are five rotatable shafts H, I, J, L, and M, supported in bearings and extending between these two plates and the plate 0. Two of over one another and at the back ofthe machine, while the two shafts I and H are similarly in the same vertical plane in the front of the machine, the shaft Jbeing in the same horizontal plane as the shaft 1. The two shafts L and I are each provided with a double screw-thread for the greater part of their length, as shown in .the figures, and the shaft M is formed with two fiat plates or vanes m,

intersecting at rightan'gles along its length,

forming what we term" the paddle-shaft. Supported between the plates D and E is a comparatively large gear-wheel e, and this wheel meshes with pinionsl and t" on the ends of the screw-shafts L and I; In addition to thepinionl the shaft L carries a pinion Z on its outer end, said end being overhung beyond the plate E fora distance equal to the 1 thickness of a gear-wheel '0', which is supported on a shaftV; carried in suitable bearings in the said plate E and in a projection E from the plate A. This shaft V is made square, and the gear-wheel v is free to move laterally thereon, although there is a spring o always tending to keep said gear-whecl pressed against the plate E. There is also a pinion v on the shaft V, which is engaged by .a rack in, form'ing part of a Z-shaped plunger X, the said plunger being carried in a cylindrical guide-piece w and having asecond rack 00 placed to engage a pinion g. on a shaft G. WVithin the cylindrical casing 00 is a spring 00 acting against a collar :0 fixed to the stem of the plunger proper, the said spring tending to always keep the plunger in the highest position of its stroke, the said plunger having a head 00 fixed to its upper end. The shaft G is supported-on suitable projections from the plate A and has fixed to it a beveled gear-wheel g, which meshes with a second bevel-gear f on a squared shaft F. Laterally movable on said shaft is a roller f around which passes an endless band N, having on its outer surface two or more series of characters, as hereinafter described. This ,band passes around a second rollerf which in turn is carried by a shaft F. The details of the roller-supporting mechanism areshown in Fig. 7 of the drawings,there beinga sleeve f preferably formed integral with the roller f and like it made to fit the squared shaft F.

A second sleevef is placed over the cylin-' drical outside surface of this sleeve, the same being provided with a rackf preferably on its, under surface. Meshing with this rack is a pinion 7' fixed to the shaft J. The roller f is constructed similarly to the roller f having, like it, mechanism whereby it may be moved laterally by rotation of the shaft J.

to threaded and passes through a correspondingly-threaded hole in the vertical plate C, a form of construction similar to that adopted for the support of the right-hand end of the shaft H, as shown at h in Fig. 1. The said end of the shaft H carries a small disk 71 placed in a recess in the vertical plate E, the whole being so constructed that a lateral motion of the shaft H toward the right would cause said wheel 72, to push the gear-wheel o into engagement either with the pinion Z or the gear-wheel Similarly the lateral motion of the shaft J causes it to push against a gear-wheel 2' on the square end of the screwshaft I, in turn causing the said gear-wheel to move from its normal position adjacent to the vertical plate 0 along its shaft and against pressure exerted by a spring 7? thereon. There is a spring h having one end fixed to the bearing-plate for the shaft F and its other end fixed on the shaft H, which always tends to turn said shaft into its original positionafter it has been revolved by means of a plunger K, as hereinafter described.

There is a pinion 7L on the shaft H just in- 5 side the plate C, and this is engaged by a rack k, formed on the end of the plunger K. The latter is provided with a head It and guided by a cylindrical piece carried on projections from the said vertical plate. As shown in Fig. 4, there is a nick or depression 10 in the stem of the plunger K, and a spring-tooth 70 is fastened to the guide-piece and placed so as to engage with said nick when the plunger has been pushed inwardly for a distance suf- 5 ficient to bring the gear-wheel 4) into mesh with the gear-wheel J. A second plunger Y is similarly carried in a cylindrical guide-piece y, supported on projections from the plate A, it having a head y and a collar g fixed to it, this being pressed against by a spiral spring g within its cylindrical guide-piece. The lower end of said plunger consists of two rectangular or frame-like pieces and g one of these, as 3 being integral with the plunger and the other being held thereto by collars y. Extending along opposite sides of this frame and within the same are two rackpieces 10, each having teeth slanted in an opposite direction to those of the other and yieldingly supported on corrugated springpieces 13 the frame containing said pieces and racks being flanged on one side, the said flange, with the second frame-piece 1 serving to retain the various parts in their correct 63 position.

The above-described frame extends around a pinion p, fixed to a shaft P, to which are when this shaft is rotated.

also fixed three disks 19 These disks are rigidly connected to each other, or they may, if desired, consist of a single piece, being provided, however, with three sets of gear-teeth extending around their peripheries for different distances, the three sets, however, all starting from the same point on the disks. There is a gear-wheel m fixed to the lefthand end of the shaft M and of such size that it is engaged by the set of teeth upon the innermost of the disks p when the latter is revolved. There are longitudinal slots a and b in the plates A and B, respectively, and these extend almost the entire length of said plates. Through the slot 1) can be seen one series of characters upon the upper surface of the band N, the set of characters displayed, whether capitals, italics, 850., depending upon the position of the rollers f and f upon their respective shafts. It will be noted that in addition to having upon it three distinct series of letters or charactersas, for example, capitals, small letters, and italics-the said band has two complete sets of each of the above series, one of said sets being merely painted or printed upon what is normally the upper surface of the band, while the other set is actual type suitably attached to what is normally its under surface. One set. of this type extends directly over the slot at in the plate A, and as the band is moved longitudinally all of the type are brought into contact from time to time with an inking-roller S. This is carried on a shaft 3, supported in suitable bearings in projections from the plate A.

Extending between the upper and lower lengths of the band is a hammer or striker R, the same having through it openings for the passage of the shafts J and I, by which it is supported and guided. It will of course be understood that the opening through which the latter of these shafts passes is of a shape to accommodate the double thread on said shaft, the striker being moved longitudinally The inwardlyprojecting end of this striker R carries a block r directly over the slot Ct in the plate A, the part r which carries said block, being further extended to within the range of motion to the vanes m on the paddle-shaft M. The said extending portion 1" is preferably made of spring material, so that when the shaft M is revolved the'projecting paddles raise the striker and as the revolution is continued allow it to drop with considerable force upon the type-carrying band.

There is a block Q, having an extension q sliding upon the upper surface of the plate 13 and formed into an index q, as shown in Fig. 1. The shaft L passes through this block and similarly to the action of the shaft I upon the block B it causes the block Q to move longitudinally when it-is rotated. The operation of the device is as follows: The ink-roller being properly supplied with ink, the typewriter ruleis grasped by the projections a and a and placed upon. a sheet of paper,

book, or other surface on which it is desired to print or write. The head of the plunger X is now pushed down, thus turning the rollersf andf and consequently the type-band, through the medium of the piniong, shaft G, gear-wheels g and f, and shaftF. The springpawl a has a tendency to retain the toothed wheel f and consequently the shaft F, in every position which would permit a type to be directly under the striker, and the inward motion of the plunger is continued until the letter which it is desired to print, as shown on the upper surface of the band, comes opposite to the index g, at which time the said spring-pawl aids in keeping the band stationary, making it unnecessary for the pressure on the plunger X to be kept absolutely uniform. WVhen this condition is secured, the type corresponding to this letter or character has been brought under the striker, the machine having beenadjusted to this end when its parts are assembled. WVhile a slight pressure is exerted u ponthe plunger X to retain the band in the desired position, the plunger Y is in turn pushed down. This revolves the pinion p, and with it the three disks 19 in the direction indicated by the arrow in Fig. 4. The first action of the teeth on these disks is to engage the gear-wheel m on the shaft M, giving it a rotary'motion and cansing the vane of said shaft to come into engagement with the end of the striker, first lifting said end and then releasing it as the revolution of the shaft is continued. The striker then comes into comparatively heavy engagement with the back or inside surface of the type-band, causing the type directly under it to be pressed against the material under it and printing a character thereon. As the plunger Y returns to its normal position under the influence of the spring'y the second set of the teeth 19, or those on the lower side of the frame y, engage the pinion p, continuingits rotation until it has turned through three hundred and sixty degrees and in its movement has brought one of the setsv of teeth on the disks p into engagement with the gear-wheel t on the shaft I. The result of this is to give the said shaft a partial revolution, which in turn results in a moving forward of the striker B through a distance of one space. The shaft L being connected to the shaft I by means of the pinions Z, c, and 'i, it also is revolved a similar amount and moves the index forward one space in the direction indicated by the arrow, Fig. 1. The two plungers are now released, and'the springs within the cylindrical casings through which they pass immediately return said plungers to their normal position. Should it be desired to print small characters instead of capitals, the plunger K is pushed down, thereby turning the shaft H with the result of moving it longitudinally through the plate D by reason of the thread construction 72 at. its right-hand end. This longitudinal motion moves the gear-wheel v on the shaft V, and

the plunger K is pushed down far enough to continue said motion until said gear-wheel is brought into mesh with the gear-wheelj on the shaft J. If now the plunger X be pushed down, its rack engaging the pinion u .will cause the gear-wheel o to be revolved thereby also turning the gear-wheelj and moving the shaft J longitudinally through the plate 0 and moving the gear-wheel 'i on the squared end of the shaft I. This action will bring this latter gear-wheel into the plane of one of the disksp and, in view of the fact that the number of teeth on each disk corresponds to the predetermined spacing to be used between the various styles of characters, the revolution of the disk 19 causes the shaft I to be turned sufficientlyto move the striker this predetermined distance forward. By this manipulation of the plunger K in connection with the plunger X the gear-wheel t' can be brought into the plane of any one of the said disks. The revolution of the shaft J imparts motion to the rack on the under side of the sleeves f so that as said shaft is movedin one direction or the other the ro1lersf andf carrying the type-band N, move upon the shafts F and F, thereby bringing anyone of the styles of type from which it is desired to print over the slot 0. on the plate A.

When the striker has reachedthe end of the line and it is desired to bring'it back to the left end of the machine in order to begin a new line, the plunger K is pushed down until the shaft H has been revolved far enough to move the gear-wheel o into mesh with the gear-wheel Z on the shaft L and then pushed downwardly to its full'extent, revolving the screw-shaft L through the gears r, '0, and Z, and the screw-shaft I from the shaft L through'its gears Z, 8, and t'. The plunger X is then allowed to return to its normal position under the influence of the spring :0 the gear-wheel o being first allowed to return to its normal position against the plate E under. the action of the spring 0 This action revolves the shafts I and L in a directionopposite to that given them by theintermittent spacing-feed from the disks p and returns the striker toward the left-hand end of the machine and the index correspondingly toward the right-hand end of the machine.
