SPECIFICATION forming part of Letters Patent N 0. 477,353, dated June 21, 1892. Application filed January 3,1891. Serial No. 376,606. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH M. ORARY, a citizen of the United States, residing at Jersey City, Hudson county, New Jersey, have invented certain new and useful Improvements in Type-Vriting Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates partly to improvements in the type-actuating mechanism of a type-writer and partly to a construction and arrangement of the mechanism for printing upon a platen below the level of such mechanism. u

The invention therefore consists partly in the combination, with atype-actuating mechanism, of devices for supporting the leaf of a book upon a platen and moving the typeactuating mechanism laterally and longitudinally over such leaf to enter a record in printed impressions in such book.

The improvements in the type-actuating mechanism and in the ribbon feeding and supporting mechanism may be used with or without the book-supporting and leaf-holding devices.

' The nature of the improvements will be understood by reference to the annexed drawings, in which- Figure 1 is a plan of the type-actuating mechanism. Fig.2 is a transverse section, where hatched, of the same on the center line of Fig.1, with type-bars and key-rods omitted. Fig. 3 is a viewof the under side of the guideplate with the feed-levers pivoted thereon. Fig. 4 is a section of the guide-plate on line 2 z in Fig. 3, with certain of the levers omitted. Fig. 5 is a plan of the bed fortheleaf-holding mechanism with the fulcrum-plate A of the type-writing mechanism and the frame and carriage for supporting the same upon the bed. Fig. 6 is a front elevation of the same. Fig. '7 is a section on line acw' in Fig. 5. Fig. 8 is a plan of the bed and book-lifter. Fig, 9 is an end view of the bed and platen. Fig.

10 is a plan of the carriage, and Fig. 11 a section of the same on line co m in Fig. 10; Fig. 12, a section of the ribbon-spools and their spindle; Fig. 13, the clutch rod detached; Fig. 14, a side view of one spool. Fig. 15 isa diagram of the line-spacing mechanism. Figs.

16 and 17 are details of the alarm. Fig. 18 shows the under side of the spacing-lever. Fig. 19 is an edge view of the same with adjacent parts in section, and Fig. 20 is a section of the lever adjacent to the ribbontwister. Fig. 21 is a side view of one of the type-bars; Fig. 22, a plan of the same; Fig. 23, the blank for making the type-bar. Fig. 24 is a side view, and Fig. 25 a plan, of the hanger; Fig. 26, a plan of two key-bars and their hangers. Fig. 27is an end View, and Fig. 28 a plan, of one of the washers for hanger-screw. Fig. 29 is a section of the hinge block and foot of the type-bar. Fig. 30 is a side view of one key-rod with the keybutton and its nut in section; Fig. 31, the flattened part of the rod. Fig. 32 represents in section the adjacent edges of the platens with portions of two leaves clamped thereon. Fig. 33 is a plan, upon a large scale, of one of the type-bars pivoted to its hanger, the latter be ing in section through the center of the sockets j The types in the present machine are intended to printdownward and the type-bars are therefore hinged at their lower ends, with their free ends held normally raised by a spring. With this arrangement of the typebars the key-rod may be pivoted directly to its upper end be provided with the key to receive the pressure of the finger, and the direct impulse of the key-rod then forces the type-bar down in opposition to the spring. The type-bars are necessarily hinged upon a circular fulcrum-plate to direct the type upon a common printing-seat, and the type bars and keys may be arranged around the entire circle or upon a segment of the same, as may be required, to furnish the desired number of characters. To guide the key-rods in a verthe type-bars, a guide-plate B is sustained above the fulcrum-plate and the key-rods are inserted through the same.

In Fig. 2 A is an annular fulcrum-plate, and B an annular guide-plate connected thereto by posts 0. Slotted hinge-blocks or hangers D are secured in a circle adjustably upon the plate A by screws E, and type-bars i are pivoted thereto, with key-rods o projected upward through the plate B. The type-bar and the type-bar near its hinge or fulcrum and tical or inclined position over the fulcra of hinge-block or hanger are shown upon a larger scale in Fig. and in Figs. 21 to 25, inclusive, the type-bar being formed by folding longitudinally a flat piece of sheet metal cut to the desired shape, as shown in Fig. 23, and pressing the two sides of the sheet metal into close contact to form the body 6 of the bar, while the ears '6 (shown upon the sheet metal in Fig. 28) are separated to form a fork. The

sides of the branches 7' which compose the fork, are provided with conical sockets 3' adapted to fit the ends of the hinge-pin d, and a screw a, with countersunk slotted head, is inserted in the branches to clamp them adjustably upon the pin to form a closely-fitting hinge. A transverse pin a is inserted through the branch adjacent to the hinge to receive the lower end of the key-rod o. A spring 19 is applied to the hinge-joint to hold the keybar normally raised, as shown in Fig. 29, the spring being formed by a coil of wire wound around the pivot-pin d, with one end applied beneath the screw 0t and the other end inserted in a hole in the hinge-block.

By forming the type-bars of a blank of sheet metal doubled the utmost lightness and stiffness are secured, and by forming branches at the foot of the type-bar with a clamp-screw a inserted through the same the bar may be hinged to the pointed pivot 61', provided upon the hanger D, and entire freedom from lost motion be secured.

In Fig. 22 it will be noticed that the sides of the sheet metal are separated a short dis tance adjacent to the branches J thus forming a trough shape, which adds materially to the stidness of the bar near its foot. By such trough-like construction the lower end of the key-rod may. be inserted between the two branches, and the pin a, which forms the pivot for such rod, may be supported securely at both ends, thus greatly increasingits firmness and durability. Such pin is shown in Fig. 26 formed as a small screw, but may be riveted in instead of tapping it.

The adjusting-screw a is shown in Figs. 21 and 26 with countersunk head, by which construction it is better adapted to clear the branches of the adjacent lever,and the hangers D may thus be set closer together and a greater nuinberof them accommodated within a given circle.

Heretofore the binding-screw E has, when tightened by a screw-driver, tended to wrench the hanger out of its normal position, and to prevent the twisting of the hangers in my construction I provide oblong washers b Figs. 26 to 28, inclusive, having one end wider than the other, with small ears b bent downward from the wider end in a suitable manner to embrace the narrow end of the adja cent washer, as shown in Fig. 26. By these means the binding-screw is rendered not only incapable of deranging the fit of the type-bar upon the pivot 61', but is also prevented from wrenching the hangers themselves out of position when the binding-screws are tightened".

The type-bars may therefore be set with the greatest nicety to apply the types exactly upon the same point of the printing-seat, and

their fit upon the pivot cl may also be readjusted at any time if they become loosened by wear.

The upper end of the key-rod 0 is reduced in size to form a shoulder 0 and is provided with a screw-thread, and the key-button 0' is provided with a nut 0 upon its under side'to screw upon the thread to the shoulder 0 The nut is secured in the key-button in the V usual manner by forming it of sheet metal in dished shape and expanding the nut by pressure within a recess 0 within the button. Such expansion is performed after the keyrods are adjusted in themachine and the nuts screwed down to their shoulders with each button upon its nut, with the index character'y (shown in Fig. 1) in the desired position. By this construction the buttons are made detachable from the key-rods, and at the same time may be restored to their initial position by screwing the nut down to the shoulder.

Three annular rows of keys are shown in Fig. 1, and in Figs. 3 and 4 is shown the means of transmitting the movement of the keys to the link 6, which actuates the spacing or feeding mechanism. A series of levers c are pivoted upon fulcra c beneath the inner edge of the guide-plate B, with the opposite ends of the levers arranged alternately over and under one another to transmit the mowment to the rear of the plate B, where the contiguous ends of two levers are coupled to a depending link 6 for actuating the feed. A series of segment-levers b are pivoted to the under side of the plate B adjacent to the alternate ends of the levers c, which at such points are provided with toes c to receive the pressure of the levers b, as shown at the right side of Fig. 4. The levers b are furnished with segments 1), projected between the several annular rows of key-rods a little distance below the plate B. Each key-rod is furnished with an offset 8, resting upon one of the segm ents, so that the actuation of any key serves to depress the segment and to actuate the connected lever 12 and the series of levers c. The offsets 8 may be made by projecting a separate piece from the key-rod, as shown at the right side of Fig. 4 and in other figures. Where the rod is offset by bending, as at sin Fig. 4, it is obviously necessary to remove the key-button from the rod to pass the rod through the guide-plate B from the under side, for which reason detachable buttons are absolutely necessary. The usual method of securing the button-disks to the key-rods by riveting and soldering would not therefore be applicable with an offset key-rod.

As the'link e, Fig. 2, is actuated by any of the keys, it is obvious that a key disconnected from a type-bar may be used as a spacing-key; but to secure a spacing-key of larger area I pro- Vide levers d, which are pivoted by pins d to the under side of the plate B and are extended inwardly at their ends across one of the levers c and outwardly beyond the front edge of the plate B. Finger-plates d are secured upon the projecting ends of the levers adjacent to the edge of the guide-plate, and thus form long spacing-keys, which are readily reached by the operator after actuating any of the character keys or buttons.

The link 6 is shown in Fig. 2 extended downward to the rear end of the spacingleverf, which is pivoted upon an ear F, attached to the rear edge of the plate A. The lever is provided with separate pawls f and I f to co-operate with a feeding-rack and with a pawl j to operate upon a ratchet-wheel k for shifting a fresh portion of ribbon beneath the type after each impression.

As it is necessary to view each impression when formed in a book of record, so as to 0bviate in the highest possible degree the introduction of errors, the ribbon adjacent to the printing-seat, where the types operate, is provided with a lifting device. This device is preferably operated to twist the ribbon upon one of its edges so as to lift the opposite edge from the paper, by which the impression last made is exposed tothe eye directly over the center of the plate B. To actuate such twisting device without complicating the mechanism, I extend the spacing-lever past the printing-seat and attach the ribbon-twister thereto.

To compact the mechanism and locate the ribbon-spools near together at an accessible point, I mount a spindle Z transversely in a bearing in the lug F, with the ratchet-wheel is attached thereto, and I fit the two spools g g upon the opposite ends of the shaft and carry the ribbon to from the same side of both spools over a loop-guide it upon the end of the spacing-lever f, thus forming a loopin the ribbon, one side of which is drawn oif from one of the spools as the opposite side is wound upon the other spool. The spools, as shown in Fig. 16, are provided each upon its outer side with clutch-teeth, formed by punching a star-shaped aperture Z in the flange of the spool. A collar g is applied to each end of the spindle to hold the spool thereon, and a notch g is formed in the collar to admit a feather. A clutch-rod Z is inserted through the spindle Z and provided with a knob Z at each end. Feathers are fitted in the opposite ends of the spindle Z to slide through the notches g in the collars. The ends'of the feathers, as shown in Fig. 13, are tapered to readily penetrate the notches in the spoolflanges, and the feathers are so adjusted upon the clutch-rod that a longitudinal movement of the rod pushes one of the feathers into one spool as the opposite feather is withdrawn from the other spool. By this construction the ratchet-wheel for shifting the ribbon may rotate continuously as the keys are actuated, and the mere shifting of the clutch-rod operates simultaneously to disengage one spool from the spindle and to engage the other spool with the spindle when, as the ribbon is drawn from the same side of both spools, the spool engaged with the spindle operates to wind up the ribbon, while the other spool is by the movement of the ribbon rotated in a direction contrary to the spindle, so that when the driving-spool is disengaged and the opposite spool engaged the motion of the ribbon is reversed. A ribbon-guide h is affixed to the lever f in a line with the loop-guide hand the printing-seat s, so that'the ribbon crosses the printing-seat and is subjected to the blows of the type.

The ribbontwister 15 consists in a slotted holder, through which the ribbon passes adjacent to the printing-seat, the holder being pivoted upon the spacing-leverf by pin t at one side of the printing-seat and held normally raised with the ribbon in a twisted position by a spring 1?. An arm t is projected from the holder toward the opposite side of the lever f and is pressed by the spring upon a bearing to, attached to the plate A. A springf holds the front end of the lever f normally raised, in which position the ribbon is not only lifted bodily from the paper, but the ribbon-twister is actuated by its spring I? to twist the ribbon, and thus freely expose the impression beneath. The depression of a key operates to raise the rear end of the lever f, the pivot to which the link 6 is attached being shown at e in Fig. 5 in the rear of the lever-fulcrum e. The keymovement therefore depresses the front end of the spacing-lever and presses the loopguide, with the ribbon, down to the paper, while the arm 25, resting upon the bearing to, rotates the twister upon its pin t and turns the ribbon into a flat position close to the pa per, asin Fig. 19. Such movement of the ribbon is effected while the type-bar is being moved downward by the key, so that the ribbon lies fiat before the type makes its impression.

The under side of the spacing-lever is furnished with a pawl f to operate upon a feedraek for moving the type-writing mechanism and the paper in relation to one another, and the spacing-lever thus performs the triple function of actuating the ribbon-lifter, actuating the spacing-pawl, and actuating the ribbon-feed by means of the pawl j.

The plates A and B, with the type-bars and the finger-rods mounted thereon, and the means for actuating the link e and the ribbon-shifter constitute what I have termed herein the type-writing meohanism,. and which may be combined with any suitable means of supporting and moving the paper to form a type-writing machine.

I have shown herein the application of the type-writing mechanism to printing entries in books of record, as tax-books, records of deeds, mortgages, 8pc. large and heavy, it would not be easy to shift them beneath the type-writing mechanism Assuch books are after making each type-impression, and I have therefore devised means for moving the typewriting mechanism laterally and longitudinally over a bed sustaining a leaf of the-book, so as to suitably space the letters in the lines and to space the lines upon the leaf. The

leaf of a book is more readily exposed to the 1 action of the type by inserting a platen beneath it, the book in such case lying underneath the platen,while the leaf is clamped to the upper side of the platen to hold it from shifting.

In Fig. 5 is shown a bed m, consisting in fourbars united at the corners. The bed is of suitable depth and size internally to receive the book (with the leaves opened) in which the inscription is desired. A frame at is fitted transversely tothe longer sides of the bed and is movable thereon to expose either leaf of the book, and may be clamped in any position by ascrew 'n, havingits shank fitted to a slotn in the side of the bed. AcarriageNis fitted to grooves 41. in the edges of the frame to move transverse to the bed-that is, up and down over the book-pagesand the inner edges of the frame are provided with racks R to fitpawls r* for moving the carriage N on the frame n for spacing the lines of type-writing. The plate A of the type-writing mechanism is provided with feet F, having rolls 1:, fitted to grooves 1) along the edges of the carriage. A feed-rack q is attached to one bar of the carriage beneath the spacing-lever) and is held movably by screws q, inserted in transverse slots at the ends of the rack. A small shaft to (see Figs. 2, 10, and 19) is pivoted along the side of the carriage and provided with two arms w, fitted to holes in the opposite ends of the rack to give it a parallel motion. A longitudinal slot g is formed in the rackand a lever g is pivoted upon a brace g upon the plate A and is provided with a pin fitted to the slot. A lever G is pivoted upon the plate A and connected by a link G with the end of the lever g and aspring G is applied to the lever G to hold the rack normally toward the pawl f upon the spacing-lever. Pressure upon the lever G operates to retract the rack from engagement with the pawls, so that the plate A, carrying the entire type-Writin g mechanism, can be retracted freely upon the carriage N to begin a new line. The pawl is held against a stop a by a spring 2, adjacent to a fixed pawl or tooth f, and is movable toward the tooth one space of the rack q. A springbarrel E (see Fig. 7) is affixed to the plate A and a cord H, wound around the same, is extendedbeneath the plate to a peg H upon the right-hand side of the carriage N to shift the type-writing mechanism as the pawl is actuated. The spring z is made very light, so that when the spacing-lever is raised and the pawl engaged with the rack q the pawl is pressed against the tooth f by the tension of the cord. The pawl, as shown in Fig. 2, is made at its end of a thin plate and moved clear of the rack at each depression of the spacing-lever when a. type is operated and is then thrown against the stop a by the spring 2'. The elevation of the spacing-lever after each type-impression engages the pawl afresh with the rack and permits the plate A to move upon the carriage by the shifting of the pawl into contact with the tooth f as already described. The entire type-writing mechanism is thus shifted upon the carriage at each vibration of the type or spacing lever.

Figs. 7 and 9 show grooves I inside the long edges of the bed m to admit a platen 1', formed of hard rubber or other suitable material. In

' Fig. 7 two such platens are shown to support simultaneously two leaves I from a book 1 The adjacent edges of the platens are crowded under a thin-edged clamp-bar J, which is fitted movably at its opposite ends in the grooves I. A transverse bar K is fitted at its ends to .slots K in the sides of the bed and moved vertically by arms L upon a cross-shaft L. A spring-lever A and a ratchet A attached to the side of the bed, furnish the means of rotating the shaft to lift the bar K and to sustain it in any position. By withdrawing the platens from the grooves'I the book I may be laid inside the open bed with the back resting upon the bar K. When laying the book upon the bar K, the frame n, with all the .printing mechanism, would be pushed to the extreme end of the bed, the contact of the screw n with the end of the slot 11. preventing it from movingtoo far. The book-may be then readily inserted in the bed and elevated to the level of the platens by the handle A By raising the book close to the platens the entire width of a leaf may be exposed upon either one of the platens, excepting a narrow margin at the back of the book. The opposite ends of the clamp-barJ are then inserted in the grooves I in the bed over the joint of the book, as shown in Fig. 7, and the leaf or leaves upon which the inscription is desired are then raised from the book and the platen or platens slid into the grooves and pressed beneath the clamp and leaf or leaves, the elastic edges of the clamp thus securing the leaf or leaves in place.

The clamp J, as shown in Figs. 7 and 32, is a thin plate of elastic material (as sheet steel or brass) reinforced at the middle with a stiffening-bar. The elastic edges of such a clamp are self-adjusting to the thickness of the leaf J, and thus operate to clamp it automatically as soon as the edge of the platen is shoved underneath the clamp and leaf lying thereon, thus holding the leaf extended upon the platen with sufficient firmness to retain it in place during the printing operation. The frame it may then be moved over either page of the book, Fig. 5 representing it over the lefthand page, with the leaf J resting upon the platen beneath the carriage. The frame A of the type-writing mechanism is then adjusted to print a line across the page, and when such line is printed the carriage is moved downward over the page by line-spac- ICO ITO

ing mechanism, as shown in Figs. 5 and 15. In these figures studs are shown inserted in plates R, extending across the bottom of the carriage at its opposite ends, and pawl-levers are shown pivoted upon the studs, with arms "r extended in opposite directions and connected by a link r Each pawl-lever has a pawl r pivoted thereon, and one of the levers is furnished with a handle R to move both levers and pawls at once. The pawls engage racks R along the edges of the frame n, and the movement of the handle R a suitable distance to the left, as indicated by the arrow 1n Fig. 5, operates to press the studs'r toward the operator and to shift the carriage downward in the frame the necessary space to print another line. A little farther movement of the handle in the same direction brings the middle of each pawl in contact with a pin 8 and throws the pawls out of the racks R as lndicated by the dotted lines in Fig. 15. The movement of the handle in the reverse direction draws the pawls downward to engage the next tooth in the rack R and at the same time throws a dog r (formed upon the arm 4*) into contact with another tooth of the rack, as shown in the full lines in Fig. 17. Springs s applied to the arms, serve to press the pawls into the racks and to hold the dog norlnally 1nto contact with the rack, which serves to lock the carriage from any displacement until the handle R is again moved to shift the carriage downward. An adjustable bell or alarm. may be applied to indicate when the line of printing has reached the edge of the leaf J. The line-spacing mechanism is operated at the end of each line until the carriage N has been traversed downward to print upon the entire leaf J, and the handle R is then adjusted to set the line-spacing mechanism in the position indicated by dotted lines in Fig. 17, when the carriage and type-writing mechanism may all be shifted again to the top of the leaf. When both the leaves exposed upon the platens I are printed, the frame at, with the type-writer mechanism, would be shifted alternately to the right and left hand end of the bed m. The operator would thus alternately expose both the'leaves of the book, the platens would be withdrawn, and fresh leaves would be raised from the book to clamp upon the platens, as before. All the pages in the book may thus be written in succession while it is held within the bed m.

The bed m is shown without any bottom plate, merely resting upon its corners or feet m; but, if preferred, abottom may be secured in the frame, so that it may be lifted and moved with the book therein, and the book thus prevented from displacement in case the apparatus is moved during an intermission of the work.

From the above description it will be seen that if the bed m be made to'admit the largest book that is intended to be printed any book of smaller dimensions may be readily inserted therein, supported upon the bar K, and

' slot.

its leaves clamped upon the platen with entire facility.

It will be noticed that the ribbon over the printing-seat is actuated with a double movement, being not only lifted from the paper by the vibration of the armf, as shown in Fig. 2, but also twisted along one edge immediately over the printing-seat. By such double movement the printed impression made by the last type is incessantly exposed to view before a subsequent impression is made and is visible to the eye of the operator, which can be applied only directly over the middle of the plate B inside the circle of type-bars shown in Fig. 1.

An alarm is shown in Figs. 5 and 6,consisting in a bell w secured upon the under side of the plate a, with a hammer pivoted adjacent to it. The hammer-handle is formed of a spring-wire 10 wound around a pin 10 with its free end carrying the hammer 10 The wire is formed with a loop v projecting in the path of a dog to, which is attached to the carriage Nf In Figs. 10 and a slot "0 is shown formed in the gib N along one edge of the carriage, with a pin 0 which is shown in Fig. 11,fitted therein, with a threaded shank and a dovetail head which holds it from turning in the The dog is formed with a thread to fit the shank of the pin, and when turned in an operative position is securely held therein by clamping upon the gib.

Fig. 17 shows a portion of the plate A inverted, with the bell and hammer attached, but arranged in their proper relation to the dog wfiwhich is shown secured upon-thegib N in the adjacent Fig. 17. The hammer-wire 10 is shown in its normal position in full lines and in dotted lines in the position to which it is shifted when actuated by the dog at the end of a line. When the dog moves in a reverse direction, as indicated by the arrow adjacent to the dog in Fig. 15, the hammer would be pressed toward the bell and the wire 10 would be bent sufficiently to let the dog pass over the projection or loop b formed upon the wire. It will be understood that one end of the wire, after it is wound around the pin to, is inserted in the plate A, as shown in Fig. 16, or otherwise secured. The coils of the wire permit the hammer to move elastically, when the coils are strained by the movement of the dog, over the loop 1 I am aware that type-writing machines have been designed before to print directly upon the leaves of a book but such machines differ from mine in two essential particulars. H They are either destitute .of any platen or other support for the book or they are provided with a vertically-adjustable table to sustain the book bodily and to press its exposed surface upward against a gage-ban Such an adjustable table has been provided with means for feeding it to space the letters and lines beneath a stationary printing mechanism; but such a construction necessitates the shifting IOC IIO

of the entire book, whateverits size or weight, after every stroke of the type. It is obvious that without any platen or any specific means of sustaining the book the machine can be merely set upon the exposed leaf and held there by its weight. It is also obvious that the feeding mechanism of a machine would require to be very powerful to shift a table with a large book of record weighing over fifty pounds thereon after each stroke of the type, and my invention furnishes a means for obviating the objections to all of these constructions by providing a platen to support a single leaf of a book, with a space beneath the same to accommodate the entire book and means for raising the back of the book close to the platen. WVith such mechanism for holding the book stationary it is obvious that the leaf can be clamped and held with perfect accuracy, while the printing mechanlsm may be by my construction made light enough to move freely for letter-spacing and line-spacing after each type-impression.

I have not claimed herein the combination,
