WILLIAM HENRY BARTEN, OF NORTH BOSTON, NEV YORK.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 499,498, dated J' une 13, 1893.

Application led May 25, 1892.

To all whom it may concern/.-

Be it known that I, WILLIAM HENRY BAR- TEN, a citizen of the United States of North America, residing at North Boston, in the county of Erie and State of New York, have invented new and useful Improvements in Type-Writing Machines, of which the following is a specification. p

My invention has relation to that class of type writing machines, in which the printing characters are arranged on a sector, wheel, or cylinder in one or more rows or banks of type. v The objects of my improvements or invention are: first, to provide an inking-pad to rest against the typevarranged upon a sector, wheel, or cylinder; second, to provide mechanism for pressing away from said type said inking-pad, and to shift to position a row or bank of type, and to rotate to position a letter or character to be printed; third, to provide a paper carriage holding against a platen vor roller the paper or object to receive the impression, and to propel the platen or roller against the letter or character to be impressed; fourth, to provide mechanism to move the paper carriage toward the left or end ot' the line the distance of the space of a lett-er or character, and at a certain distance or number of spaces before reaching the end of the line to give a signal, as the ringing of a bell, and when the end of the line is reached, to prevent the printing of another character, but to move the paper carriage back to the right or the beginning of the line, and at the same time to turn the feed roll and raise the paper ready to receive the nextline, and as soon as the beginning of said next line is reached, to impress the letter or chacacter which would'be impressed beyond the end of the former line or on the character already printed in said former line, in the first space of said next line.

All of the operating parts for accomplishing the objects mentioned above, and others that may appear are driven by any one of the key levers, except the operating parts for shifting to position a row or bank of type.

My invention accordingly consists of the combinations, constructions, and arrangements of parts, as above, and as hereinafter Serial No. 434,377. (No model.) I

lmore particularly described in the specification, and pointed out in the claims.

ln the accompanying drawings like letters` and like numbers refer to like parts in all the iigures.

A, A', A2, A3, designate respectively the top, bottom, right, and left sides of the housingor outer frame to which the operating parts of the machine are directly or indirectly attached. A9 represents the top A of the housing extended forward said extended part being bent down and attached to the bottom A'; the front part A8 A9 contains slots B, B', &:c., only a sufficient number being shown to illustrate the principle, and avoid crowding the drawings; the slots B, B', dac., have their upper ends in a straight line parallel to the bottom A' of the housing, said upper ends forminga rest for the key levers when not depressed by the operator to drive the machinery; the side A9 also contains slots between the key lever slots, to allow different levers to pass through the IOO side A9, and to act as guides for the levers; the slot through which the shift lever passes is of peculiar form one side being a straight edge, and the other edge being graduated in a step like form, the steps approaching the straight edge toward the bottom. A small groove orniche extends into the side from each step, so that when the shift lever is arrested by a certain step a small projection from the shift lever catches into the small groove or niche, and holds in position a certain row or bank of type upon the type wheel.

A10, A11 are parallel supports arranged one above the other, and attached to the right and left sides of the housing, to the bottom, top or in any manner to give rigidity to said support.

The housing is made of a single piece, or may be of more pieces of sheet metal or any material that can be cut and bent into the desired shape, size, and form as shown in Fig. 1.

a represents the type wheel, sector or cylinder which is attached to the upright shaft a. The shaft a is journaled in the parallel supports A10, A11 so that t-he shaft a and type wheel ct may be shifted vertically or rotated horizontally.

a2 represents a head at the bottom of the shaft a. Between said head and the lower side of the lower support A11 is a spiral spring a3, of which one end is attached to the head a2, andthe other end to the lower side of the lower support A11; said spring is to press the shaft downward, and to rotate the shaft and type wheel to its original position after a character .has been printed and the key lever released, also when the key lever `is depressed to steady the movement of the shaft and type wheel, and facilitate vertical as wellA as horizontal alignment; a4 is a small gear wheel or pinion rigidly attached to the type wheel shaft, and by which the shaft and type wheel are rotated. Said pinion also acts as a shoulder to prevent the shaft and type wheel from falling below a certain distance and to rest the shaft upon the upper side of the lower support A11, when the upper bank or row of type is in position to print.

a5 is a collar surrounding the type wheel shaft. Under this collar a shift lever catches to shift the type wheel vertically.

ZJ designates the type shield composed of a thin partly cylindrical shaped substance having a hole b through which asin gle character is admitted at a time, when the platen or roller against which the paper or object to receive the print is held is propelled against the type shield, and the type shield against the type wheel, and the paper against the character appearing through the hole b; there is a projection b2 on the upper side or edge of the type shield just above the hole Zn to work in combination with the scale 7L', and clasp t, in printing characters in certain places, indenting paragraphs, arranging columns, dto.

b3, b3 designate hooks by which the shield is hung to the support A10. The ends of said hooks are turned upward to strike and rest against the lower side of the support A10, after the shield has fallen forward a certain distance on account of its own weight, so as not to be in contact with either the type wheel, or paper when the key lever is released or the machine is at rest.

c represents the ink pad composed of felt or other substance suitable for holding ink and imparting the saine to the type faces when the pad is pressed against them; said pad is attached to the inner side of a segment of a hollow cylindrical shaped base c cornposed of metal or other suitable material that will preserve its cylindrical form; in this case the ink pad (including base c) is composed of two semi-cylindrical segments pivoted together to the upper support A10 so that the segments may be pressed apart or away from the type wheel, in order that the type wheel may be rotated, or shifted, without the type faces rubbing or dragging against the ink pad, and so that the ends of the segments of the pad toward the type shield, and paper will be out of the way, and allow the platen or roller, paperor object to receive the print, and type shield to be propelled against the type wheel; the two segments are pressed together or against the type wheel by a spring e2; the two segments are connected by a toggle joint c3, which on being straightened presses apart or away from the type wheel the ink pad segments. This toggle joint is attached to the lower sides of the pad segments, and works in a depression or groove in the upper side of the support A10; a pin or projec tion from the knee of the toggle joint at c4 passes through a slot in the support A10, said slot being large enough to give the pin or projection from the knee of the toggle joint at e0 sufficient play for working back and forth.

c5 designates a lever pivoted to the lower side of the support A10 and held against a projection e0 on the lower side of said support by a spring @Tone end of said lever extending behind the pin or projection which projects through the slot in the ,support A1" from the knee of the before said toggle joint.

es is another lever attached to the lower side of the support A10 in a manner similar, and for the same purpose as lever c5; these levers are arranged one a little above the other so that when one is drawn forward to straighten the toggle joint, the other is not affected.

CZ represents the shift lever fulcrunied to the upright support CZ. One end of said shift lever extends beneath the collar a5, and the other end extending through the slot C in the side A0, that side of the lever having a proj ection d2, which is toward the step like graduated side. Said projection catches into the small niches or grooves to hold in position a row or bank of type; to said shift levercl is piv- ICO TIO

oted abell crank cZScZ d5; At d4, one arm of said bell crank extends upward, and has attached to its upper end CZ3 arod or lever ZG of which the other end is attached to the lever c5; the other arm d5 @Z4 extends through the slot C, and a little above the end ofthe shift lever cZ protruding through said slot C, so that when the end d5 is depressed by thekeyorfinger piece at d5, the ink pad segments will be pressed away from the type wheel, after which d5 will press against the forward end of the lever CZ, and press down the same and raise the type wheel.

e represents a sector of a gear wheel pivoted to the upper side of the support A, and held against the projection e when said sector is at rest, by a spring e2. The periphery esisof sufficient width so that when the type wheel shaft is shifted vertically, and the pinion a4 with it the sector of the gear wheel and the pinion will not be thrown out of union.

f designates a rod or lever, of which one end is attached to a gear wheel sector e, and the other end of said rod or lever to the rod t t2 of the pivoted rocking frame or bail t in order that' when said rocking frame is depressed a certain distance, by a certain key lever, the gear wheel sector is rotated a certain distance, and a certain letter or character ,is/rotated to position for printing.

g g g2 designate a bell crank pivoted to the rod or lever f at g', The arm g g of said bell crank extends upward and has attached to its upper end g a rod g3 of which the other end is attached to the lever cs, Theother arm g g2 extends forward and just below the rod t t2 of the pivoted rockingframe or bail t. .The hole in the end of the rod f through which the rod t t2 of the pivoted rocking frame or bail t passes is somewhat oblong, so that when the rod t t2 is depressed by any one of the key levers, the end g2 of the bell crank g g g2 will be depressed without affecting rod f, and the segments of the ink pads pressed away from the type-wheel. As soon as the end g2 is depressed to the bottom of the hole the rod fis affected and pressed down toward the front, sector e drawn forward, pinion d4, shaft a', type wheel a rotated, and a letter or character brought to position.

`Zt represents a roller or platen, against which the paper or object to receive the printing is held by the bar h upon which is marked a4 scale, and by the roller h2.

h3, h4 designate the upright pieces in which the scale bar Zt', roller/or platen h, and roller h2 are journaled;,the lower ends of the upright pieces hay?? are joined by a rod or bar h5, thelower ends of the upright pieces forming an even and continuons edge or surface with bar h5; by the bar h5 the paper carriage is attached to the bottom housingvA by the closed boxes h6, h at the center, (to do away with friction the open boxes may be formed of a small wheel as illustratedn'Fg- 10 journaled in the bottom housing vertically, and so as to rotate in the direction in which the paper carriage moves, parallel to the front edge of the machine, said wheel having a groove in its periphery, the groove forminga guide or socket in which the paper carriage could rotate, and move in the direction of its length, also the center journals could be made of a wheel of the kind just described, and a staple, or something of that description attached over the top of bar h5 to the bottom housing A to hold the rod h5 down into the groove on said wheels) so as to allow the paper carriage to be propelled against, and away from the type wheel, and moved in the direction of the length of the paper carriage.

lrepresents a clasp having the two numbers t', 712, which are pressed together by a spring or its equivalent at t', so that when an object is put between said members i', 'i2 the clasp will be firmly attached to the object; the clasp serves to indicate when clasped on the scale bar h', where'to print a character, begin a heading, line, indent aparagraph, &c.; from the member t" extends a projection 3 by the member 2, and from the member Z2 another projection Z4 extending byt", so that when the projections are pressed together the members i', 2 arevpressed apart, and the clasp may be taken off from an object, or attached to it; this clasp may also be used for other purposes than with the scale and projection b2 of the shield; asv to hold together two or more copies when nianifolding.

j represents a spring attached to the upright piece h4, and pressing the scale rod against the paper and roller or platen.

IOC

la represents a ratchet wheel attached to the i end of the feed roll h.

la designates a pawl pivoted to the upright piece h3. Said pawl falls into the teeth of the ratchet wheel, and prevents the feed roll from turning backward. k2 designates a reciprocating lever pivoted to the upright piece h3, and has jointed to itself a small pawl k3 which when the lever is moved in one direction by the spring Zc4 slides over the teeth of the ratchet wheel Za, but when the lower end of lever k2 is pressed in the opposite direction by the projection Zthe pawl drops into the teeth of the ratchet wheel, and thustnrns the IIO feed roll andv raises the paper; the pawl k3 is pressed toward the teeth of the ratchet wheel by the spring 704 and pawl Za by spring k6.

Zis'a projection extending across the line in which the lever k2 at its lower end'passes.

Said projection is attached to a base Z having a slot Z2 through which a screw Z3 passes to attach said projection to the bottom housing A',

end of lever k2 is arrested by the projection Z. m designates a thumb screw by which the feed roll may be rotated.

'n designates a projection from the upright piece h4. To this projection a hammer-a is hung which when the paper carriage is moved to Within a certain number of spaces from the end of the line strikes a bell n2 attached by a support and base similar to Z. to the bottom housing A' when the platen or roller is propelled against the type wheel.

o represents a lever or rod having in one end a hole o through which the rod or bar h1@ passes last said rod being attached at its op posite ends to the upright pieces h3, 7b4 of the paper carriage and parallel to and a little above rod h5. Lever o also hasa hole o2 in the other end the rod '11"122 of the pivoted rocking frame or bail o passing through said hole o2.

03 is a lever hinged to the bottom housing A', and pivoted at its upper end to lever o, a spring 04, attached to the bottom housing A and the crank or lever 03, so as to draw the lever o toward the paper carriage, act as a guide or support to prevent the rod or lever o from moving sidewise when the paper carriage moves in the direction of its length, to propel the roller or platen h away from the type wheel, and to draw up toward the perpendicular the pivoted rocking frameor bail c after the key lever has been released. The joints of this lever o, with its connecting and supporting parts are made sufficiently loose to permit it to move endwise tobring the platen against the type wheel.

p designates a cord or its equivalent of which one end is attached to an eye in the upright piece 71,3 and the other end attached to, and wound upon a barrel Q or its equivalent.

designates another cord of which one end is attached t-o an eye in the upright piece h4, and the other end attached to,`and wound upon the barrel Q or its equivalent a little above or below cord p, so that when the barrel Q is rotated one way cord p is wound upon said barrel, and cord p is wound olf and the paper carriage moves toward the right, and when said barrel is rotated in the opposite direction cord p is wound upon the barrel, cord p is wound olf and the paper carriage moved toward the left.

The barrel Q is journaled in the bottom housing A2 A3, and lower support A11; upon the upper side of said barrel is a ratchet crown Wheel or its equivalent. Apawl Q is pivoted to the lever or rod 0 so that when rod ois drawn forward by depressing any one of the key levers, the pawl Q slides over the teeth of said ratchet crown wheel, and when the key lever is released and rod 0 pressed toward the paper carriage by lever 03 and spring o4, the pawl Q catches into the teeth of said ratchet crown wheel, and rotates barrel Q winds up cord p and off cord p and moves the paper carriage one space toward the left.

Q2, Q2, dac., designate holes into which the and begins to raise the same as a key leveris depressed, and rod o drawn toward the front, and pawl Q over the projection Q3. As the pawl Q is raised a hook Q4 on its upper side is arrested against a sector arm Q5 which is then drawn forward the sector of a gear wheel QG rotated, also the pinion Q7 attached to the axle of the barrel Q, thus rotating barrel Q, winding upon said barrel cord p and winding off p and moving the paper carriage toward the right or beginning of the next line; the sector of a gear wheel Q6 is pivoted to the lower side of the lower housing A by a pivot Q8.

fr is a rod attached at one end to the radius Q5 and the other end to the lever r2 which is pivoted to the bottom housing A at r', and extends upwardly leaning a little toward the front, and at its upper end bent forward eX- tending through the slot r3 in the side A, and has attached to its upper end a finger piece or key r4; the object of the rod r, and lever fr? is to move the carriage toward the right, or left by pressing key r4 down toward the front, or raising key r4 toward the back, or paper carriage; the rod r and lever r2 are especially convenient for moving the paper carriage to-V Ward the right or beginning of a line, when the last line of a paragraph, or any line which ends before the vertical line has been reached in which all the other lines end.

s s', s3 s4, &c., designate key levers of which the front ends s', s4, &c., all end in a straight line parallel to the front and bottom sides of the housing; the key levers are fulcrumed in a line, or on a rod mt' parallel to the bottom housing, but not to the side A9 or linein which the front ends of the key levers end; the key levers extend beyond their respective points of fulcrum, and are Weighted at their farther ends to a rise, and rest against the upper ends of slots B, B', d50., the ends of the key levers extending toward the front from their points of fulcrum, so that when any key is depressed the others will not be affected.

t designates a rocking frame or bail pivoted at its opposite ends to the housing; the upper edge of this rocking frame rests against, or nearly against the lower sides of the key levers parallel to the line in which the key levers end in front, said rocking frame being quite near to the bar u to at one end so that when a key lever at the right hand side of the key board is depressed it will not depress toward the front the rocking frame as far as a key lever farther to the left, and no two key levers will depress the rocking frame forward the same distance. The front ends of the key levers are all depressed the same distance, and are all arrested by a cross bar parallel to the bottom housing, but slanting a little toward the back or paper carriage as said bar approaches the right side of the ma- IOO IIO

chine, or the front ends of said levers may be arrested by the bottom housing A', to facilitate alignment or to rotate the type-wheel to its eXact position;

v designates another rocking frameor bail arranged in the same manner as the rocking frame t only more to the front and not quite parallel to the rocking framet'the right-hand end being a little farther from the front than the adjacent end of the framet because when a key lever at the end @Eis depressed its front -end will be fartherifrom the front end of the housing A than the end of a lever at the left or near the left hand end since the levers are fulcrumed a greater distance from the front than the levers near the other end; the frame o is always depressed toward the front'the same distance no matter by what key lever it is depressed.

The finger pieces S5, te., are raised a little above thelevers to which they are attached lso that when one of the levers is depressed,

l said space leverbeing fulcrumed and arranged 3 as any other key for rintinfr letters or chary 7,5 p C acters except that when said space lever is depressed there is rotated to position aspace upon the type wheel and as the platen and paper are propelled against the type wheel no impression is made; a space may be left in each of the diiferent rows or banks of type.l The spaces in the different rows or banks of type should all be in avertical line above one another, also should the letters or characters upon the type wheel be above onev another inA vertical lines.

y In my type writing machine the type wheels, sectors, or cylinders are removable from the shaft a', by means of a connecting screw 6 and others having dierent styles of letters may be substituted for them at will. As will be seen the screw is partly in t-he type wheel and partly in the shaft thereof, whereby the wheel is locked upon the shaft against vertical movement as well as horizontal rotation, and the screw will not jar loose, thus making a simple means for quickly and readily removing a wheel, and placing another in its stead.

To provide for substituting different styles of letters or characters upon the key levers s s, &c., the finger pieces s2, S5, dac., contain on their lower sides a concave or female screw, and the upright pieces s?, S9, or finger piece supports have screws cut on their upper ends, so that linger pieces representing a diierent style of letters may be readily turned on to the finger piece supports.

The operation of my invention is as follows: Upon depressing any one of the key levers the barst t2, n v2 of the rocking frame t t 2153, and c) o u2 fc3 are depressed toward the front, bar t t2 presses down the end g2 of the bell crank g g g2, draws forward end g, rod g3, lever c4, toggle joint c3, and presses apart or away from the type wheel the ink pad segments, which being accomplished the bar t t2 is arrested by the bottom of the oblong hole in the front end of rod f, rod fis drawn toward the front also the gear wheel sector e, whichrotates pinion a4, shaft a', type wheel a, and a letter or character is brought to position for printing, at the same time rod fvv? is pressed down toward the front, rod o drawn forward, also rod h10 of the paper carriage, and the roller or platen h propelled with the paper-or object to receive the printing against the type shield b, and against a type face protruding through hole b in said type shield; as the key lever is released it is raised against the upper end of the slot in A9 through which the key lever passes, and by which the keylever is guided, by the weight attached to the lever beyond the point to which the lever is fulcrumed, the double crank is raised to its original position and the ink pad segments are pressed together or against the type wheel by the spring c2 through lever c4, rod g3, and bell crank g g g2, and the springs e2, and a3 which rotate to their original position the shaft a', type wheel a, pinion a4 gear wheel sector e3, and draws up against or nearly against the lower sides of the key levers the rod t t2 by rod f; the rocking frame o v o2 fus is drawn to its original position by spring 04, crank, or lever o3, and rod o, which also propels the roller or platen by the rod hw away from the type wheel, the type shield falling away by its own weight from the type wheel, and pawl q catches into a tooth of the ratchet crown wheel rotates the barrel q, winds upon the same cord p', olie cord p, and moves'the paper carriage the space of a letter or character toward the left. When the paper carriage gets to within a certain number of spaces from the end of the line, hammer u strikes a bell as the platen or roller is propelled forward against the type wheel, and

IIO

if there will not be space enough in the line i for the whole word the operator will be given an opportunity to break the word correctly. When the end of the line is reached the projection g3 will be underneath the pawl q', and

as the operator depresses another keyswith the intention of printing the letter or character or making-a space the type wheel, `6to., is driven as usual, but rod o drawsforward over the projection 'g3 pawl q', and raises the same.

The hook g4 of said pawl is then arrested by the arm qi? sector Q6 rotates pinion Q7, and barrel q upon which is wound cord p and unwound cord p', and the paper carriage moved toward the right or beginning of the next line, and as the paper carriage moves toward the right the lower end of lever Wis arrested and pressed back by the projection Z, and the feed roll 7L rotated through the ratchet k and pawl 7.53 which is jointed to the upper end of the lever 7a2, and as soon asthe paper carriage geis t) the beginning of the next line the paper is raised to receive said next line in its proper place, the letter or character will be opposite the hole bin the type shield and the paper or object to receive the printing will be pressed against the type shield, and character by the platen or roller. To Mshift to position a row or bank of type it is only necessary to depress the finger piece or forward en (l d5 of the bell crank d3 (Z4 d5 which draws forward the end cl3, rod d, lever e7, toggle joint c3, and presses apart or away from the type wheel the ink pad segments. Vhen this is accomplished the arm (l5 is arrested -by the front end of lever (l, which is then depressed and type wheel shaft and type wheel shifted vertically by collar (L5, and as soon as the desired row or bank of type comes into position the lever (Z is arrested by the step designed for that row or bank of type, and the projection (l2 is pushed into a small niche or groove which holds in position the desired row or bank of type, and as (Z5 is released the pad segments are pressed together or against the type Wheel by the spring c2, toggle c3 is pushed back or together, lever c7 drawn back, also rod (ZG, and end (Z3 of bell crank (Z3 (Z4 (Z5, and end (Z5 raised. To move the paper carriage to the right or beginning of a line When the last line of a paragraph, or any line which ends before the vertical line has been reached in which all the other lines end, or to move the paper carriage toward the right or left without affecting the type wheel, or propel the roller or platen against the type wheel, and without affecting the parts which drive the type Wheel, ink pad, or propel the carriage to and from the type wheel, the linger piece 0'4 is pressed up toward the paper carriage, rod or lever r, and radius g5 also in that direction, and the pinion (17 and barrel q are rotated by the gear wheel sector q, and cord p is wound on the barrel q, and p off,and paper carriage moved toward the left; or if the iinger piece r4 is depressed toward the front rod r, radius Q5 are drawn forward, Q7 and q rotated by the gear wheel sector q, cord p is Wound on the barrel q, cord p off, and the paper carriage is moved toward the right.

As the construction and arrangement of the novel features of my invention may be variously modified without departing from the spirit of the same, I do not limit myself to the exact device described, and shown in the specification and drawings. Certain features of my invention are applicable to other classes of type writing machines than wheel, sector, or cylinder machines. I therefore do not confine my invention to a use of the same in connection with type wheel, sector, or cylinder machines, but reserve the right to embody the same in type writingmachines generally, and in which said modes of operation may be embodied.
