TYPE-=WRITING MACHINE.

SPECIFICATION" forming part of Letters Patent No, 312,981, dated February 24, 1885.

Application filed December 26. 1853.

T0 aZZ whom it may concern.-

Be it known that I, DIANLY G. DODGE, a citizen of the United States of America, residing at Charlotte, .in the county of Eaton and State of Michigan, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to improvements in type-writing machines, having for its object to effect the operation of writing or printing with facility and without the tapping of keys, while it is adapted also for writing or printing in blank-books, for which type-writers, as usually constructed, are not available; and the invention consists of the combination and arrangement of parts, substantially as hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a plan view of my type-writer. Fig. 2 is a horizontal section on line as 00. Fig. 8 is a vertical section of the type-wheel carriage. Fig. 4 is a bottom plan view of the same. Fig. 5 is a view of the handle inverted. Fig. 6 is a longitudinal sect-ion of one of the parts detached. Fig. 7 is a vertical sectional VlO \V of one of the types and its adj unctive parts. Fig. 8 is a detail view. Fig. 9 is avertical'sectional view wit-h parts broken away. Fig. 10 is a longitudinal sectional view of my invention on the line y y.

Inthe organization of my invention I construct a frame composed,preferably,of two end bars, A A,with downwardly bent or extended ends fastened to longitudinal base-bars A,se cured horizontally upon inwardly-projecting horizontal plateextensions c c of said end bars, A A, thereby allowing the suspension of the printing or type carriage between said side or base bars. To the front end of this frame is suitably connected the handle B, and to and between the two end pieces, 0 and G", of said frame are screwed or otherwise fastened two spaced-apart bars, I) b, to the upper and lower sides of which are screwed metal plates 0 0, having slots (1 d,and which are rounded at one end and partly so at the other, and fit into coincident recesses formed in the end bars.

At one end of the two spaced-apart bars I) b is an end piece 0 to which is secured one (Modem of the end bars, A A. Said end piece (3 has an opening in its center wherein the wheel I is held in position.

Screwed or otherwise fastened to the sides of the bars I) I) are metallic plates 0 0, having slots 0 0 extending nearly from end to end thereof.

D is the type-wheel carriage, composed, preferably, (although capable of variation in structure) of a disk or dial, D having lat oral and downwardly bent or flanged exten sion D, fully clearing the two spaced-apart bars 2) b. One of the downwardly-bent or flanged extensions D is passed in under the type-wheel carriage D, and rigidly connected to the other downwardly-bent or flanged eX- tension D at a, thus forming the lower bar or plate, D.

To the under side of the top plate D of the carriage D, one being arranged on each side of and closely to the two spaced-apart bars 6 b,are bolted or otherwise secured downwardly projecting right angled plates or brackets e, the inner face ends of which pro ject into the slots 0 c to effect the proper guiding of the carriage upon the bed-bars.

In one arm D and extending a short distance inward and through the transverse bottom-connecting-plate,D",is also aslot, f, through which the required or depressed type is caused to project and impart its impression to the surface of the paper designed to receive such impression in effecting the printing or writing operation.

Through the longitudinal slots (1 d of the plates 0 0 passes the shaft E, bearing at its lower end centrally in the type-wheel D of the carriage D, while above said type-wheel D it passes through the disk or dial D andis provided above the dial with a pointer, g, and at its upper end with a lever, 9, having aknob, g, at its outer end. The knobbed lever is capable of being moved upwardly and returned to its original position to permit the adjustment of other hereinaftendescribed parts in position.

Articulated to an arm or between two disks, h, ofa bracket, 0 suitably secured to extension D of the carriage D is a ring-lever, F, said connection being effected by an arm, h, fixed thereto, said latter arm having a perforated disk, h, at its outer end sandwiched between the two disks h. Although this may be the preferable way of connecting the ring-lever F, any other convenient means for the purpose may be adopted. Diametrically opposite the arm h said ring-lever F is provided with a second arm, h", which, (while the arm h rests on aspring, i, secured to the dial D rests on a spring plunger or pin, G, recessed or notched to more effectually hold said arm h thereon, and adapted to have movement in an aperture in the disk or dial D and to come into con tact with a coincident type head or extension, presently referred to, when force is applied to the ring-lever. 'The plunger is elevated by its spring when pressure is removed.

Disposed in a circle near the outer edge or margin of the type-wheel D, and so as to 00- cupy a coincident series of apertures or holes in said typewheel, are a series of types, H, composed of the letters of the alphabet, punctuation marks, figures, or other characters which are designed to effect the printing or writing.

Secured to the type-wheel D and arranged in a circle adjacent to the types H, are a series of vertical rods or studs, H, encircled by spiral springs Hfiwhich act from-the type-wheel D against'perforated rectangular extensions H at the upper ends of the type-stems,through' which projections the studs H extend, as

shown in Figs. 3 and 7. The upper ends of the studs H are provided with heads or enlargements which engage with the upper sides of the rectangular extensions H of the types H, and arrest their upward movement caused by the action of the spiral springs surrounding the studs H for the purpose of effecting the retraction of the type after the downward motion necessary to be given them for producing contact of the same with the material to be printed. The studs H by reason of passing through the rectangular extensions H at the upper ends of the type-stems, operate to hold them in correct perpendicular positions and thereby bring the type-faces squarely against the paper to be printed, thus securing full impressions of the same.

Between the slotted plates 0 C is arranged an endless chain belt, I, passing over wheels I 1 the wheel I beingv disposed in one end between the two plates 0 O, with its periphery contiguous to the curvature in said end, and the wheel l located in the opening in the end piece 0 with its periphery adjacent to the curvature in that end, before described. The chain is thus guided and retained in position on the pulleys or wheels. The shaft E passes through an oblong square block or sleeve, L, within the box or case formed by the slotted plates 0 0, side bars, I) b, and end bars, 0 C The sleeve L is provided at one side with a groove, L, having a tooth, L which projects through the contiguous link of the chain I, as

shown in Fig. 2. The tooth L is so formed that it will be engaged by the chain I when it moves in one direction, and be cleared of the chain I by means of a lever, K, when it moves in an opposite direction, as will be hereinafter more fully described. When the chain moves and engages with the tooth L", the type-carriage is moved in a forward direction. The side bar, I), is sufficiently extended inwardly, as indicated by the dotted lines in Fig. 1, to engage with the side of the oblong sleeve or block L, and thus hold it in line with the chain I, the inner edge or side of the bar I) being rabbeted to allow the chain I to pass freely, all which is fully shown-in Fig. 3.

Upon the wheel 1 at the handle end of the maehine,is formed or connected a ratchet, 1 with which engages a dog or pawl, J, projecting through a'slot, j, in that end of the box or case formed by end pieces, 0 G and plates 0 O, and pivoted to a thumb-lever, J, pivoted upon the lower side of the handle 13, and capable of convenient manipulation by the thumb of the left-hand, while the type-wheel is being operated by the right-hand. This pawl or dog.

is held in its proper position by a spring, j, in contact with the thumb-lever J, (see Fig.

5,) secured to the inclosingcase, so as to partly cover the slotj, and bear on the dog or pawl when under pressure. The thumb-lever J is also held in position as against too great a rearward movement by means of a stop, j, and is moved to manipulate the dog or pawl, which acts to propel one of the chain-belt wheels, when the chain-belt wheel will be driven and the carriage be moved longitudinally along its support, intermediate mechanism, presently described, assisting to accomplish this end.

K is a lever, pivoted to the upper side of the dial D", next to the handle end of the machine, and arranged between the dial and box and parallel with the slot in the plate C, the forward end of said lever having a small upright handle, while its opposite end is bent downward through said slot and thence to one side where it terminates in a tooth, k. By press- IlO- ing said tooth 7c of the lever K against said chain, it will throw the chain I out of engage ment with the tooth L of the block L, and allow the type-wheel carriage to be returned to any desired point over which it has already been passed.

The block L is arranged to slide in ways formed between the plates 0 and G and the two spaced-apart bars I) and b, and to permit the type-wheel shaft to pass through it and through itself. In the center of one side is a groove for the carriageoperating chain to pass through, thus admitting it to slide with the carriage. In the forward end of this block is a recess, is, within which the inner toothed end ofthe lever K works or is capable ofhaving movement as it is projected into or against and contact with the passing type of the type-wheel to cause the rotation of the pads, and the propor application of the ink to the types. The bottom bar of the carriage may be semi-circularly recessed on each side to allow, the closer arrangement to each other of the inking pads or disks, while the latter, together with their connecting bar, are readily removable by means of the above arrangement, to enable the re-inking or-resupplyiug with ink of the pads. With this construction of devices, it will be seen that with the tooth L engaging the chain I, the type-wheel carriage will,when subjected to the action of the parts, as above described, be moved along its support at intervals occurring, as may be regulated by the action of the thumb on the lever J, while by the turning of the type-wheel shaft E, by the action of the right hand upon its handle, and the depression of the handle, the process of writing or printing will take place.

Preparatory to the writing or printing operation, the carriage is moved to the left or handle end of the supporting case of frame by slightly moving the lever K in the direction of the arrow W thus causing the disengagement of the chain I with the tooth L of the block L, which allows the carriage to bemovcd toward the handle end of the machine without operating the chain and its wheels, which are prevented from having a reverse movement by means of the pawl J. The handle of the type-wheel shaft is now grasped and turned (the chain having again been brought into engagement with thetooth L of the block L) until the pointer on said shaft points to the de sired specific letter or type on the dial D (which is designed to be correspondingly lettered or marked with the type in the wheel,) when, by pressing downward upon the handle, the plunger will be forced upon and de press the corresponding letter or mark of the wheel-type, so as to make its impression on the surface of the paper upon which it is designed to print or write. The thumb'lever J is now operated so as to cause its pawl or dog to actuate the ratchet-wheel of one of the chain or belt operating wheels,which willdrive said chain and effect the movement of the carriage the required distance or interval of making the next type-impression, which operation of moving the type wheel and depressing the lype,effectingthe printing 0peration,and mov ing the wheel-carriage at intervals through out the operation, will be continued until the required amount of printing or writing has been accomplished.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent, isp 1. In a type-writing machine, the combination of the typewheel, and the type-wheel carriage D, having disk or dial D said disk or dial having lateral and downwardly-bent or flanged extensions D", one forming the lower bar, D, having slot f for passage of the type when depressed, with the central vertical rotating shaft, E, having pointer 91 and lever 9, constructed substantially as described, and arranged to operate as specified, and for the purpose set forth.
