TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 524,816, dated August 21, 1894.

Application filed August 19, 1893. Serial No. 483,591- (No model.)

To all whom it may concern:

Be it known that I, J osit HERRAN Y BOLADO,

a citizen of the Republic of Mexico, residing at Aguas Oalient-es,Mexico, have invented a new and'useful Improvement in Type-Writing Machines; and the following is declared to be a full, clear, and exact description of the same.

My present invention is designed as an improvement upon the device shown and described in my Letters Patent, dated October veyed on a traveling carriage, and in my pres-' ent invention I employ more positive and efficient mechanism for carrying out the general features of my former machine.

In my present invention I employ a revolvin g longitudinally movable cylinder upon the surface of which the type characters are formed, and this cylinder is provided with perforations agreeing in number and arrangement with the type characters. This cylinder is moved .along endwise and rotated on its supporting shaft to the extent predetermined according to the type character to be brought into position, and this is accomplished by various mechanical devices hereinafter more fully described.

I employ a minimum number of keys arranged in groups of two or more to be operated simultaneously or singly, so as to bring into place for printing the desired type character, and I employ a traveling carriage for the sheet of paper upon which the impression is given and suitable mechanism operated by the depression of the keys to impart a step by step feeding movement to said carriage. I also employ an inking ribbon passing through suitable guides across the face of the type cylinder and to which I prefer to impart a progressive step by step movement with and by each depression of the keys. This inking ribbon I prefer to be an endless band.

The mechanism for carrying out the aforesaid operations is hereinafter more particularly described.

In the drawings, Figure 1 is a side elevation of my improved typewriter with the traveling carriage incross section. Fig. 2 is a plan of the same with the central portion of the traveling carriage removed. Fig. 3 is a v5 is a sectional plan at approximately the line a: w of Fig. 1. Fig. 6 is a view illustrating the manner of locking the mechanism when the carriage is thrown back. Fig. 7 is a sectional plan of the type cylinder and the devices connected therewith, and Fig. '8 is a detached elevation illustrating the rack pinion and cam movement.

A suitable support A carries the frame plate B of the machine and to which the typewriter mechanism is connected. There is a vertical slotted'front plate 0, a main standard D, standards E E F G and H and pivot lugs I I I I and 1 all connected to and rising from the said plate B to carry parts of the mechanism. i

The finger keys are shown in groups of two, viz. a'a-b bc c, and they are connected to lovers 6 e e e e and e that pass through the slotted plates 0 and extend through the machine and are pivoted at their back ends to a shaft K in the bearing lugs I I.

The auxiliary keys d d come at each side of the aforesaid groups of keys and they are connected to auxiliary shafts ff also passing through the plate 0 and back to the shaft K to which they are pivoted. The bars 9 pass across beneath the aforesaid groups of levers and-are connected at their ends to the short levers h h also pivoted on the shaft K.

Each of the levers e e e e e and 6 has a plate spring 2 fastened to the plateB, said springs serving to maintain the said levers and the finger keys carried thereby in an elevated position with the lovers bearing against the plate 0 at the upper ends of their slots, see Fig. 4:.

The main standard D carries at its upper end a bearing sleeve t' and a crank arm t" pivoted on said sleeve. A helical spring 3 is connected at one end to the crank arm 1 and at its other end to an arm 4 secured to the plate B. Passing through an eye on the outer end of the crank arm 2" is a rod 5 to which is connected a turn buckle 6 having an eye at its lower end through which the bar 9 passes, and this spring 3 serves thus to hold up the bars 9 g and. short levers h h; the upward movement is determined by the bars 9 g coming up against the under side of the aforesaid levers connected to the finger keys.

Each of the levers e e e e e and c has connected rigidly to it a vertically disposed rack 7; each rack 7 meshes with a pinion 8 and each pinion in turn with a segmental toothed cam 9. The racks 7, pinionsB and cams 9 are in pairs between the grouped 1evers e e',e e and 6 6 the pinions 8 and cams 9 being upon short shafts in suitable bearing frames 10 connected to the plate B. The racks 7 and pinions 8 agree in size, but the operative surfaces of the cams in each pair do not agree, the one having a greater reach than the other for the reasons hereinafter set forth. These cams 9 operate rocking levers for imparting to the type cylinder rotary and longitudinal movements for bringing the type characters into position to be printed.

The type cylinder is represented at 70 and the same is longitudinally movable along and can be rotated with the shaft 70. The type cylinder has type characters upon one portion of its surface and holes in the surfaces of the other portion which agree in number, position and arrangement with the type characters. The shaft 70' is pivoted at one end in the standard D and at the other end in the plate 0. This shaft 70 is spirally grooved at plate 14 and the longitudinal rods 15 connect the said head and plate. Sleeves Z Z surround the shaft 70', the sleeve Z being connected to the head 13 and the sleeve Z coming between it and the end of the cylinder 70, and a helical spring 16 surrounds the shaft is between the plate 14 and the end of the cylinder. Links 17 connect the sleeves Z Z together and pivotally to an arm hereinafter more fully described. p

I employ disks l8 and an intermediate ratchet 19 secured to the shaft 70', also a disk 20 and pinion 22 connected together and loose on said shaft and a coil spring 21 like a watch spring, one end of which is secured to the disk 20 and the other end to the shaft is.

A hand lever m is pivoted to the plate G and to it is pivoted a rack m engaging the pinion 22. This hand lever hasa pivoted arm and roller 23 and integral finger bar 2e and a spring 25 acts to hold the roller 23 against the edge of the plate 0 and in one at a time of the notches in its upper edge.

A levern is pivoted to a rock shaft 0 in the standards 1 I and to the upper end of this lever is pivoted s pawl arm n whose extreme end engages be teeth of the ratchet19. This pawl arm n has a spring 28 and :finger 30 to keep it down in place. The other end of the rock shaft 0 carries a bar and roller 0 which come beneath the edges of the pairof cams 9 betweenthe levers e e. The lever n is made with a pin a and upon the back of the plate 0 is pivoted a lever 26 of peculiar form and Whose upper end bears against the under side of the roller 23. A spring 27 connects the short arm of the lever to the bed of the machine and acts to elevate said lever. If the roller 23 should rest on the upper edge of the plate 0 instead of in one of the notches 29, the lever 26 is raised and its end comes in the path of the pin 'n and prevents the movement of the lever 17. and its pawl n. a

The rods 15 are curved downwardly as shown anda pivot pin 31 passes through both rods. The bell crank lever 32 is pivoted to the plate B and the pivot pin 31 passes through its upper slotted end, and there are'rollers on the other end of said lever that come beneath the pair of cams 9 between'the group of levers e e and a spring 40 connected to the lever 32 on said lever.

The rock shaft 1" is pivoted in the standards I and E and it carries a bar and roller 0' that comebeneath the pair of cams 9 between the group of levers e 6 An arm 8 is connected to and rises from the rock shaft rand carries a frame at its upper end in which are parallel rods s'one above the other. An arm 33 passes between the rods 3' and is provided with a roller 34: coming at one side of the upper rod 3 and a pin coming at the opposite side, and the arm 33 is connected to one of the links 17 or formed as a continuation of one of said links. The standard G carries a frame 35 through the arms of which a vertically placed and pointed bar 36 moves, and said bar is surrounded by a-helical spring 37. The standard F is hollow and slotted and in the lower part thereof is a pivoted arm 38 one end of which comes beneath the bar 36, and the other end beneath a finger 39 on the bar g.

The type cylinder and its attendant mechanism heretofore described operates as follows:The keys at b and 0 effect a minimum amount of movement and the keys a b c a maximum amount of movement. The keys at b and 0 may be operated singly,but the depression of the key a depresses a; I) depresses b; and c depresses 0. These keys may be operated in groups to impress the desired type characters, and an illustration of such grouping is shown in my application for Letters Patent herein referred to. The depression of the keys or a and their levers e e operates the rack 7, pinions 8 and cams 9. To depress the roller and bar 0', turn the rock shaft 0, move the lever 72 and pawl n, ratchet l9 and rotate the shaft k and type cylinder it; the key 0. gives about twice the rotary movement to the cylinder that is imparted by the key a. This movement strains IIO and this swings the arm38 and imparts an upward movement to the bar 36, the point of which enters a hole in the type cylinder 70 at the end of 'the stroke and holds the same while the paper is impressed with the desired letter and also acts to correct the alignment. The depression of the keys I) b and their levers e e operates their racks 7, pinions 8, cams 9, swinging the bell crank lever 32 and through the pin 31 longitudinally moves the arms 15, head 13, plate 14, sleeves Z Z, links 17 and arm' 33 and type cylinder 75 and simultaneously rotates the type cylinder by means of its pin 12 and the spiral groove 11. y The depression of the key 6' causes the increased movement to the aforesaid parts because of its larger cam 9, and the spring 40 returns or draws back these parts to the place of beginning. The depression of the keys c and their levers e e operates their racks 7,. pinions 8, cams 9, depressing the bar and roller 'r, swinging the rock shaft 1' and moving the arm 3 and its frame and rods s and arm 33 inward toward the center of the machine. This movement tends to spread the links 17 and because the sleeve Z and head 13 are now stationary to move along the sleeve Z and type cylinder is, compressing the spring 16 and simultaneously rotating the type cylinder k. The spring 16 returns the parts to a normal condition when released and in all cases the aforesaid keys and their levers are raised by the action of their springs 2 assisted by the spring 3, crank arm '5', rod 5 and connections to the bar g. Each depression of one of the keys and levers operates the arm 38 to raise the bar 36 in a hole in the type cylinder is in the manner and for the purpose hereinbefore set forth.

The office of the hand lever m, rack m, arm and roller 23, spring 25 and notches 29 is to change the type case, or in other words, to turn the type cylinder from capitals to small letters or from small letters to figures and characters or from any one of these to any other one. This is done by swinging the hand lever and bringing the roller into one of the notches 29 where it is held by the spring 25, and simultaneously by the moveshaft is and type cylinder 79, the finger 24 on the bar 23 as the roller passes over from one notch 29 to the other raising the pawl 72. against the action of the spring 28 so as to permit the ratchet 19 to rotate. As the roller drops into a notch 29 the spring 28 draws down the pawl n into engagement with the teeth of the ratchet 19. Should the roller 23 accidentally rest upon the upper edge of the plate 0 and not in a notch 29 the spring 27 raises the arm 26 so that its extreme and free end comes in the pat-h of the pin 72 and the movement of the mechanism is arrested.

The inking ribbon is preferably an endless band passing around the machine and over the type characters of the cylinder hand the following mechanism is provided to carry said ribbon.

ets on the inner side of the plate B carry guide rollers t i and the inking ribbon. passes around these rollers. On the shaft of the inking and feed roller t is a ratchet 41 and on the upper end of the bar 42 is a spring pawl 43 operating said ratchet. This bar 42 is guided in ways 44 and is provided with pins 45 coming at each side of the projecting end of the shaft 9, so that as the shaft g rises and falls it acts upon these pins 45, imparting a vertical movement to the bar 42 that effects the movement of the pawl 43 and bya step by step movement rotates the inking and feed roller tand imparts a movement to the ribbon L. The roller 46 bears upon the inking ribbon and causes it to take up ink from the roller 25, and the arm 47 bears upon the ribbon and acts to take up the slack. The hollow standard F receives a vertically moving rod 48 which carries a U-shaped piecei49 whose upper ends are made as guides for the ribbon L, and a helical spring within said standard is so constructed that the parts are held in an elevated position.

Thecarriage for carryingthe sheet of paper to be printed upon is composed of the following parts: The rod or barupasses through and is supported by the standard D, and said rod may be separable as shown in Fig. 3 for convenience in packing and transportation. The ends 0 o'are cdnnected by the tooth feed rack u and indicator plate '20, which latter extends across the front of the carriage, and also by the bar 50. The feed and impression roller b the guide roller w and the bar b all extend across the carriage and the rollers 12 and w are practically in contact, the sheet of paper 0 passing around beneath the roller b and between the rollers 19 and w. The bar 19 carries a roller 51 pressing the sheet against the bar 50, and a spring 52 ,bears against a flattened side of the hub of the finger button 53 on the end of the barb to give the desired pressure. On the end of the roller 19 there is a toothed wheel 0 and finger button 54 and a pawl 55 on a sliding bar 01 is to be operated to rotate the roller b or the said roller may be operated by the button 54 in either direction upon elevating the pawl 55-by the arm connected thereto. In the position shown in Fig. l the carriage is in position for work and it is supported by the roller f upon which bears the rack u. The roller f is pivoted upon an arm 56 around the sleeve 1 of the standard D and the rear end of this arm 56 has connected to it a helical spring (1 which is fastened to and strained by the finger bar 57. The arm 56 rests normally on the outer end of the crank arm t" and the carriage is held up by said crank armand the spring 3:

A bar f is pivoted to the standard H and said bar extends through the machine across bar 1" has an upward extension with a mortise to receive the end of the bell crank lever h (see Fig. 6) and the upper end of this lever comes beneath a roller 58 on the arm 56 and the office of this lever It will be hereinafter set forth. A spring f serves tokeep the bar f in an elevated position and to return it thereto after being depressed and released.

A lever h is pivoted to the standard D and this lever It has a roller 59,at its upper end,

a weight 60 at the other side of and below the pivot, and a hook 61 at its extreme lower end, and when the carriage is thrown back, as shown in Fig. 6, the feed rack it rests upon the roller 59 and swings the lever carrying the hook 61 forward so that it comes beneath the end of the arm 62 which is upon the shaft g, and as all the levers of the keys and auxiliary keys come above this shaft it will be apparent that these levers are locked and cannot be depressed accidentally or at all un-.

connected to the bearing sleeve t of the stand ard D and the periphery of said plate 4? passes through between two of the teeth of the feed rack u, and the forward end of this plate 2' is slotted at 66 and beveled in opposite directions to form two oppositely placed inclines or teeth. These inclines act upon the teeth of the rack u with the downward and upward movement of the carriage t0 feed along the carriage with a step by step movement which is equal to one tooth at a time or its equivalent one letter. The segment plate 71 acts to prevent the longitudinal movement of the carriage at all points except when'thrown completely back and resting upon the roller 59, and while resting upon the rollerthe carriage can be moved freely along any desired amount in either direction before being turned back to a normal position. In this latter'position with the feed rack to resting upon the roller 59 the weight of the carriage presses upon and swings the lever 71. on its pivot, raising the weight 60 and pressing the hook 6l'beneaththe end of the arm 62, which arm is upon the cross bar g. This looks the parts so that any attempt to accidentally press down one of the keys is resisted because this bar 9 upon which test all the levers of the keys is held by the hook- 61 and finger 62. v

A disk 67 is connected eccentrically by a screw to the key lever f, and the lower edge of .said disk comes below the lower edge of the said lever and there is a plate 68 secured to the bed plate or support. This disk 67 when adjusted eccentrically forms a stop to the downward movement of the lever fby coming against the plate 68.

The office of the keys (1 d is to feed along the carriage by a step by step motion through the intervention of the levers ff, cross bar g, rod 5, crank arm 1" and roller ff, the extent of movement being so governed that the paper in the carriage does not quite come down to the type of the cylinder 70, and this movement is assisted because the upper end of the bell crank lever h is not moved entirely out from under the roller 58, therefore the carriage is prevented from dropping its entire distance.

In the depression of the keys at a b b and c 0 their levers e e e e e e are depressed to a slightly greater extent than'the levers ff. In this operation the cross bar g, rod 5, crank arm 11 and roller f are also operated together with the bell crank lever k to drop the carriage, but the moment that the upper end of the said lever 71 passes away from beneath the roller 58 the arm 56 is freed and the carriage which it supported is given a final drop to give the impression of the type cylinder upon the paper. The depression of the keys (1 d and their levers f f? also efiects another operation, viz., that of moving along the inking ribbon by a step by step motion imparted by the end of the'bar 9 operating the pins 45, the Vertically moving bar 42 and spring pawl 43 and ratchet 41.

A'pointer arm Z is connected to the standard E and extends up to the front of the numbered indicator plate to on the front of the type carriage, and said arm is set to point to a number which will be found to correspond to a number on the upper face of the feed rack 11/ at the tooth notch of the rack through which extends the segment plate '5 and these numbers are in unison with the feed of the carriage.

When the carriage is slightly raised the IIO lower end of the segment plate is visible and it will be found to align with a letter or character impressed upon the sheet of paper, and by further raising the carriage the number of this character will be visible on the face of the feed rack u. When it is desired to correct a letter the carriage is quickly swung back, moved along and swung forward along the segment-plate upon the numbered notch of the desired number, and in all cases the numbers of the feed rack u and indicator plate w agree.
