To a/ZZ whom# may concern:
Be it known that we, DOCK D. HARR and JOHN L. HARR, citizens of the United States,re siding at Belmond, in the county of fright and State of Iowa, have invented certain new and useful Improvements in Type-VVriting Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to type-writing iriachines; and it consists in the novel construction and combination ofthe parts, hereinafter fully described and claimed.
'i In the drawings, Figure l is a plan view oi the machine from above with the carriage removed; and Fig. 1L is the front part of the bed ot the machine with the letter-plate, which could not be shown on the same sheet with Fig. l. Fig. 2 is a plan view from above of the mechanism under the bed, also showing portions of the bed. Fig. 3 is an end view ot' the complete machine, looking from the right; and Fig. a is a similar end view looking from the left. Fig. is a front view of the machine. Fig. t3 is a plan view of 'the carriage from above. Fig. 7 is a cross-section through the machine, taken on the line a: a: in l`ig..5. Fig. 8 is a longitudinal section through the inking device. Fig. 9 is a detail View of the device for ringing the bell.
A is the bed of the machine, and a and a are brackets secured to the ends of the bed.
A is a bar at the back ot the machine secured between the brackets a and a.
B is a bracket secured to the front of the bed for carrying the pointer B. Six grooved rollers b are journaled upon pins b', projecting from the brackets a, d', and B andthe bar A', for supporting the carriage.
The carriage C is provided with end t rames c and c', and C are bars extending between the end frames and resting in the grooved rollers b. Stationary plates 2, provided with hooked upper ends 3, engage with the bars C over t-he said rollers, so that the bars are kept in the grooves and are free to slide lonand d is the hand-wheel for revolving the roller.
E E are plates pivot-ed on the shaft d at the ends ot' the roller and coupled together by the longitudinal bars 4, 5, and 6. The plate E is provided with a lug 7, and 8 is a bracket secured to the said lug. A springactuated catch 9 is pivoted to the bracket S by the pin 10 and engages with either of the notches 11 or 12 on the end frame c.
F is the line-spacing spring, secured to the said bracket S and engaging with the wheelf7 which is secured on the shaft (Z and. is provided with angular teeth, which permit the roller to be turned in either direction against the pressure of the spring when sufficient force is applied to the hand-wheel cl.
D are bars pivoted to the frames c and c and extending across the machine, for supporting the paper clear of the type-plate.
A back guide-plate F` for the paper is provided, and consists of a curved plate pivoted at its upper edge upon the bar et, and held in contact with the roller by the springs f at each end oi' it. f
G is the front guide-plate for the paper, consisting of a curved plate pivoted at. its upper edge upon the bar G, and provided with guide-strips G at each end, which overlap and bear upon the back guide-plate F', being pressed against it by means of the sprngs 13 on the bar o. The hammer strikes the type upwardly against the paper on the roller through the space la between the two guideplates F and G, as will be more fully described hereinafter. Y Y
A projecting lug l5 is secured tothe guideplat-e G and raises it clear of the roller when amine thework, the catch 9 is disengaged ICO from the notch 1l, and the roller, together with the plates E E', the shaft d, and everything mounted on the said shaft, is turned over, upward, and backward until the catch 9 engages with the notch 12 at the top of the end frame c. This brings the lowerindex g into view, and the carriage can be slid longitudinally when the roller is turned back again, S0 as to bring any desired numeral of the upper index opposite to the pointer, and thereby bring the paper-space opposite to the corresponding numeral of the lower index over the hammer, the numeral of the lower index opposite to the said space of thc paper desired to be brought over the hammer being noted before turning back the roller.
H is the oscillating type-plate secured on the shaft H journaled in the frame 7L under the carriage, and h is a toothed segment also secured on the said shaft. The typebars are pivoted in two semicircular rows upon the pivot-wires 17, which are carried in the grooves 1S of the type-plate Il. Only a few of the type-bars are shown, as they are all alike, and the type 19 may bc secured to the free ends of the bars, as shown,by the screws 20, or the type may be formed in one piece with the type-bars. The typeplatc H is provided with cross-grooves 21 for the pivoted ends of the type-bars to work in, and has a series of projections 22 around its outer edge. A roller 23 is carried by a spring 24, which is supported by the bracket 25, secured to the frame 7L, and the said roller bears in the spaces between the said projections 22, and by its slight pressure and friction causes the typeplatc when oscillated to stop in those positions which bring the type-bars directly over the hammer. The type-plate is oscillated by means of the lever I, secu red on the sleeve t', which is pivoted upon the pin I', projecting from the frame h, and t' is a toothed segment secured to the upper part of the said sleeve 1." and gearing into the aforesaid toothed segment 71..
J is the letter-plate secured over the lever I to the front part of the frame It, andj is the indicator secured to the said lever and extending over the letter-plate.
J2 is the ornamental connecting portion which secures the letter-plate J to the frame h, so that the letter-plate rests upon the bed and slides back and forth with the frame.
lVhen the indicator is brought over a letter or character on the letter-plate by turning the lever I, the corresponding type is brought over the hammer. The inner row of type preferably prints the small letters and the outer row the capital letters, and the numerals, punctuation, and other marks are divided between the two rows.
The frame 7L slides back and forth in the grooved cross-guides J so that the type of both rows may be brought over the hammer. A round pillar j projects downwardly from the frame h, and 26 is a spring secured to the bottom of this pillar and to the bed, and normally holding the inner row of type-bars over the hammer. A pillar 27 projects from the rear part of the frame h and forms the bearing for the shaft H. A plate 28 is secured to the bed, and is provided with an adjustable stop screw 29 for the pillar 27 to strike against to limit the forward movement of the frame 7L. A plate SO is also secured to the bed, and is provided with an adjustable stopscrew 31 for the platej to strike against to limit the rearward movement of the frame 7L. The frame 7b is moved forward by the spring 2G, and is moved rearward by the mechanism which will now be described.
K is the linger-key for pushing back the frame 7L. This key is mounted on the stem 7,; and slides vertically in the boss K on the bed. A pin 7c projects from the stem k through the slot 32 in the boss K and prevents the stetig from turning around in the boss. A shaft is journaled in bearings 34, projecting from the bed, and 35 is an arm secured on the said shaft for the pin k to bear against. A lever 36 is pivoted to the bed by the pin 37, and is provided with the fork 38 at one end, which engages with the round pillar j. A rod 39 pivotally connects the other end of the lever 36 with the lever 40.secured upon the end of the shaft 33. lVhen the key K is depressed, the shaft 33 is turned in its bea-rings, and the frame 7L is pushed back by the forked lever connected to the lever 36 on the shaft, as above described.
In order that the carriage may be moved longitudinally, a ratchet-toothed rack 41 is provided, and is secured to the end frames c c bythe brackets 42. This carriage is moved to the right automatically by means of the spring-actuated wheel 43, and the cord 44 wound upon the said wheel and attached to the left-hand end of the rack. The wheel 43 is journaled on the pin 45, projecting from the bracket 49, which is secured to the bracket a. A retaining-pawl 47 is pivoted to the bar A by the pin 48 and engages with the rack, so that the carriage may be held at any tooth of the rack as the rack is moved to the left.
L is the spacing-key for moving the carriage to the left step by step. This key is secured on the stem 50, provided with a projecting pin 5l working in the slot 52 of the boss 53 on the bed. This pin prevents the stem from revolving; and 54 is a spring bearing against the said pin for holding the key in its raised position. A shaft 55 is journaled in bearings 5G, projecting from the bed, and 56 is an arm secured on the said shaft and bearing against the pin 51. The shaft 55 also has a lever 57 secured upon its end. A vertical lever 58 is journaled on the shaft 59, which is supported by the brackets 60, secured to the bracket u, and the lower end of this lever 58 is pivotally connected to the upper end of the lever by means of thelink 61. Apawl 62 is pivoted by the pin G3 to the upper end of the lever 58 and engages with the teeth of the rack. When the key L is depressed, it turns IIO the shaft 55 and rocks the lever 5S, thereby moving the pawl 62 longitudinally and permitting it to drop into the next tooth of the rack. A spring G4, coiled upon the shaft 59 and connected to the lever 58, pulls back the pawl 62 and causes the carriage to be moved for the space of one ratchet-tooth directly the key is released. The pawl 62 passes under the retaining-pawl 47 5 but the slight vertical motion of the paWl 62 in passing over the ratchet-teeth is not sufficient to raise the pawl 47 out of engagement with the rack.
M is the key for working the hammer, secured to the bell-crank lever m, which is pivoted to the bracket a by the pin on. The short arm of the bell-crank lever is pivotally connected to the bottom of the lever 63 by the rod 64, and the said lever is pivoted to the lug 63 on the bed by the pin 65. An arm 66 projects from the lever 63 and engages With an arm G4', secured upon the spacer-shaft 55, so that the spacer-pawl 62 is moved to actuate the carriage each time the hammer-key is depressed.
N is the hammer secured upon the shaftn, which is journaled in the bearings n', projecting from the bed, and N is an arm project-V ing downwardly from the said shaft. A longitudinal shaft 70 is journaled in the bearings 7l, projecting from the bed, and 72 is a crank secured upon the shaft70 and adapted to bear against the said arm l A lever 7 3 is secured upon the opposite end of the shaft 707 and 74 is a rod which pivotally connects the lever 73 with the said lever 63. When the hammer-key M is depressed, it rocks the lever 63 and turns the shaft 70, and the crank 72 raises the hammer and causes it tov strike the type-bar over it and prints a character upon the surface of the paper on the roller.
P is the key for working the line-spacing device and causing` the carriage to be automaticallytraversed to the right. This key is provided with a stem p and works in the boss P on the bed, which boss is provided with the slots p. A lever 7 5 is pivoted bythe pin 7G to the lug 77 on the bed, and the end of this leverprojects through a hole in the stem p and through the slotsp of the boss P. A lever 8O is also pivoted on the pin 7G and has a projecting lip Sl on its short end under the said lever 75. The other end of the lever 8O engages With the lower end of a rod 82, the upper end of which is pivoted to the pawl G2. When the key P is depressed, the rod 82 is raised and the pawl 62 is disengaged from the teeth of the rack. In being thus raised by the rod 82 the pawl 62 strikes against the pawl 47 and liftsit also out of engagement with the ratchet-teeth of the rack. The carriage then moves automatically to the right, being propelled by the spring-actuated Wheel 43 and the cord 44, as hereinbefore described.
The movement of the key P, which permits the carriage to travel to the right, simultaneously turns the paper-roller for the distance between two adjacent lines, so that a new line can be commenced at once.
This line-spacing device consists of alongitudinal bar R, having its ends pivoted on the shaft CZ outside the carriage frames c and c. A ratchet-wheel r is secured upon the opposite end of the shaft b from the hand-wheel.
R is a pawl pivoted to t-he bar R by the pin r', for turning the ratchet-Wheel when the said bar is raised, and S3 is a pin projecting from the frame c to prevent the roller from being turned for more than a one-line space at each movement of the said bar. The pawl R is provided with a curved end S4, which keeps it from being thrown over out of gear altogether with the ratchet-wheel, and a spur 85 projects from the lower part of the pawl R and rests upon the stop S6, secured to the frame c. The stop 86 normally holds the pawl out of gear with the ratchet-Wheel, so that the paper-roller is held in position by the spring F and wheel f, which permit it to be turned in either direction by applying sufficient force to thehand-wheel. The pawl R falls in to gear with the ratchet-Wheel teeth as soon as the bar R is raised sufficiently to lift the spur S5 clear of the stop. t
The bar R is lifted by depressing the key P in the following manner: S is a vertical rod sliding in ther guide S, secured to the bed and provided with the cranked upper end s, which engages with the said bar R. A shaft s is journaled in the bearings S7, projecting from the bed,and 88 is a crank on the end of the shaft s', which engages with the end of the lever 7 5,which proj ects-through the stem p. A lever S9 is secured upon the other end of the shaft s from the crank 8S, and is provided with the forked end S9,which engages with the lower end of the rod S. The depression of the keyPturns the shaft s" and raises the rod S and bar R, causing the paper-'roller to be revolved for the space between two adjacent lines.
T is an adjustable stop resting on the rear bar A and provided with the springt forthe end frame o of the carriage to strike against when the carriage reaches the end of its travel toward the right. The stop T regulates the width of the margin left unprinted on the left hand of the sheet of paper. The. stop T is provided with, a longitudinally-slotted shank T, and t is a thumb-nut engaging with the end of a screw passing through the slot of the shank T and through a hole in the plate 90, secured to the bar A. The shank T is graduated and marked, so that margins of any desired width may be arranged for.
U is the bell, secured on a pillar projecting from the bar A', for giving warning before the end of each line is reached. j
U is a bell-crank lever, provided with the hammer u for striking the bell, and pi'voted on the pin u, projecting from the bar A.
Y V is the bell-hammer trip,provided with the hook t* at its lower end and the inclined portion c at its upper end. This trip is pivotcd to the short arm of the lever U by the IOC.
IZO
pin 90', and its 'hook i" rests against the head of the pin u.
Y is a pin projecting from the end frame c. Then the carriage is near the end of its travel toward the left, the pin Y strikes the inclined portion v of the trip and raises the hammer u. The hammer falls and rings the bell as soon as the pin lets go the trip. The hook r disengages from the pin-head when the pin strikes the other side of the trip during the return movement of the carriage toward the right, so that the trip turns upon its pivot-pin 90 and permits the pin V to pass it.
W is the inking device. (Shown to an enlarged scale in Fig. 8.) This inking device consists of an inner cylinder u', in which the ink is placed, and an outer cylinder w', carrying a disk of felt XV. The outer cylinder w is provided with a longitudinal tube 91, and 91 is a thumb-nut screwed on the said tube over the open end of the said outer cylinder next to the head of the inner cylinder. Meeting holes 92 are provided in both cylinders behind the felt disk for the ink to iiow through, and the area of the open passages through these holes is regulated by means of the slot 92 in the outer cylinder andthe guide-screw 93, proj ecting from the inner c ylinder through the said slot. The area of the ink-passage and the supply of ink to the felt is regulated by turning the inner cylinder within the outer cylinder by means of the projecting head of the screw 93, so as to slide the meeting holes more or less out of line with each other.
The inking device is journaled upon the round end 93 of the inking-lever Y, which is pivoted on the top of the shaft H', and the felt disk inks both rows of type simultaneously as the said rows are oscillated under it. The disk has beveled edges and is free to move longitudinally on the end of the lever Y, so that it may adjust itself to bear uniformly against the type. The felt disk is normally held at the center of the machine by means of the link y, which slides in the guide y', secured to the frame h.
Y is along pin which projects from the lever 58, which is the lever which operates the traversing pawl (i2 every time the hammer is raised by depressing the key M. The link y is provided at one end with a hole, which slides upon the long pin Y as the frame h is moved back and forth, so that the said pin and link are always operatively connected together. The other end of the link y is provided with a pin 9i, which works in a slot 94 in the lever Y, and 95 is a spring secured to the lever Y for holding the pin 9i at one end of the slot.
Each time the hammer is raised to strike a type-bar the felt disk is moved in the arc of a circle to one side of the type-bar thus about to be struck by means of the link y and lever Y, so that the newly-inked type may be raised by the hammer and leave its impression on the paper above it. The felt disk returns to its central position directly the key M is released. The spring 95 permits the pin 9ito have a little play in its slotand relieves the inking device from sudden jerks and jars.
Z is a spring secured to the inking-lever Y, and provided with the head .e for the typebars to strike against when raised by the hammer. This head is always held over the typebar being raised, it prevents it from being struck too hard against the paper, and depresses it out of the return-path of the inking-disk directly the hammer-key M is released.
