SPECIFICATION forming part of LettersPatent No. 470,633, dated March 8, 1892. Application filed May 4, 1891. Serial No. 391,4. (No model.)
To all whom it may concern:
Be it known that 1, CHARLES W. WALKER, a citizen of the United States, residing at Strang, county of Fillmore, and State of Nebraska, have invented certain new and useful Improvementsin Type-WritingMachines, of which the followingis a specification.
The object of this invention is to construct a type-writer of few pieces, having a longitudinal movable type-carryin g bar capable of a vertical movement and a paper-roller having an escapement which is operated by the same movement of the hand of the operator that presses the type-bar in contact with the paper-roller.
In the accompanying drawings, Figure 1 is an isometrical representation of a type-writer embodying my invention as seen from the front. Fig. 2 is an isometrical representation of the same type-writer as seen from the rear. Fig. 3 is a lengthwise central section through the type-bar with the bar depressed in position to give an impression. Fig. 4: is an elevation of the oscillating platform, showing the pivoted dog connected therewith, and the various positions which they occupy are shown by the dotted lines. Fig. 5 is a longitudinal section through that portion of the frame supporting the paper-carrying roll, showing the construction of the roll and its supports.
This invention relates to that class of typewriters in which a type-bar is employed. carrying all the necessary type and which is moved to bring any one type in position to give its impression. The base of my typewriter in this instance consists of two bars 1 and 2, secured together, the bar 2 extending at right angles to the bar 1, forming a T- shaped frame. Rising from the upper surface of the transverse portion of my frame are two brackets 3, each of which is provided with ahole, through which passes a guide-bar 4, and this bar is rigidly afiixed to its supporting-brackets. Ext-ending downward from a carriage-body 5, directly above the guidebar, are two cars 6, perforated'to allow the passage of the guide-bar upon which they and the carriage which they support are free to slide across the face of the machine. Supported on two brackets 7 and 8 above the carriage-bodyis the'roll 9, upon which is the sheet of paper to be written on and upon which the in close contact with the roll when being i wound thereon, I provide three strips of sheet metal 10, secured to the carriage-body and, curving upward, pressed against the backward face of the paper-roll. At one end 11 of the paper-roll, outside the supporting-bracket and at equal intervals in its circumference,I provide marks which,when coincident to a mark on the upper edge of the supporting-bracket 7, enable a uniform spacing of the lines of the writing.
To hold the end of the paper to the paperroll when commencing to wind it thereon, I out a longitudinal slot 12 (shown in Fig. 3) into the surface of the roll, into which I slip the upper edge of the sheet and wind it about the roller as I print the lines. Icut this slot into the roll not straight toward the center, but inclined toward that side of the roll from which the paper is wound, thus giving atighter bite upon the edge of the paper bearing against the acute angle thus formed at the side of the slot.
In the forward edgeof the carriage-body, at equal distances apart, is a series of pins 13, forming a part of the mechanism that produces the transverse movement of the carriage necessary for the proper spacing of the letters. Extending downward from the rear side of the carriage-body is a leg 14, resting on the upper surface of the transverse portion 1 of the base of the frame and sliding thereon when the carriage is moved along its guide-bar. This leg holds the carriage in its upright position. The longitudinal or stem portion 2 of the T-frame I make with sides slanting toward the rear side of the machine, and pivoted between these sides near their rear ends is a platform 15, capable of a slight oscillating movement on its pivot 16, and this oscillating platform is held upon a level with the top edges of the side pieces of the frame by the action of a flat spring 17, located under the platform. Upon this oscillating platform I secure two pieces 18 and 19, located near together, and in the upper edge of the piece 18 I cut as manynotches 20 as I have characters in my'type-bar. Secured to the side of this notched upright piece near to its upper edge I provide an index 21, marked with a letter, figure, or character coinciding with each notch in the upright rack. In the space between these two vertical side pieces I place my typebar 22, which is a straight stick having a button 23 on its upper rear end, which is to be grasped in the hand of the operator. EX- tending transversely through the end of the bar near to the handle is a metallic pin or pointer 24, one end of which rests on the upper edge of the supporting-frame, and the other end in one of the notches in the toothed rack 20. The letters and characters are so arranged on the under side of the type-bar that the letter on the bar corresponding to the letter on the index opposite to the notch in which the pointer bears is directly over the roller and in line with letters or characters previously printed. By pressing downward on the button of the type-bar the spring below the platform is bent and the platform and type-bar are depressed, bringing a letter of the type-bar in contact with the paper. When the pressure is removed, the platform resumes its normal position and the type-bar may be moved to any other place on the index, and the letter or character corresponding thereto will be impressed on the paper when the bar is again depressed.
It is obvious that a transverse motion of the paper will be necessary properly to space the letters in the line, and thisI obtain in the following manner: As I before stated, the rear edge of the carriage-body is provided with projecting pins 13 at suitable intervals throughout its length. On the oscillating platform at its forward end I provide a dog 25,
which when the platform is depressed is free to extricate itself from between the pins in the carriage-body; but when the platform rises to its normal position the d og, striking against a rigid stop 26, presents an inclined plane-to one of the pins in the carriage-body, forcing the carriage the space of one letter to theleft, .and this is repeated at each movement of the oscillating platform. This dogis of substantially V shape, one arm,however, beingshorter than the other and pivoted at its apex, the long arm lying horizontal and prevented bya stop from downward movement. When the oscillating platform is in its normal position, the horizontal portion of the dog is in contact with the under face of the pins in the carriage-body and the short arm of the V extends between the pins. When the platform is depressed, the dog turns on its pivot, allowing the short arm to slip from between the pins without moving the carriage; but when the platform returns the long arm of the V is stopped in a horizontal position, pressing the inclined outer edge of the short arm against one of the pins and sliding the carriage one space to the left. (Fully shown in Fig. 4.) That the type-bar shall present but one letter to the paper I provide a shield 27. This shield is pivoted to the vertical pieces 18 and 19, which carry the type-bar, and holds its position by friction, being capable, however, of movement on its pivot. Thus when the type bar is depressed the shield is pressed against the roll, and the letter, coinciding with an opening 28, makes its imprint on the paper. When the platform resumes its position, the shield moves bodily with it, thus notblurring or blotting the letter printed.
To provide for the inking of the type, I place in the forward end of the oscillating frame a roll 29, covered with some soft absorbent material, upon which I place the ink. The type-bar rests on and is drawn backward and forward over the surface of this roll as the pointer is moved to the various characters on the index, thus keeping the type properly inked at all times.
I claim as my invention 1. A, type-writer comprising a T-shaped frame, a guide-bar secured thereto, a carriage mounted thereon, a paper-roller supported by said carriage, projections extending from said carriage, an oscillating platform, a type-bar capable of a longitudinal movement on said platform, and a dog on the platform to engage the projections on the carriage.
2. A type-bar com prising a T-shaped frame, a guide-bar secured to the transverse portion thereof, a carriage mounted on said guide-bar and capable of a movement along its length, a projection extending downward from the carriage and resting on the frame, a paperroller mounted on the carriage, the roller being longitudinally slotted to receive and retain the edge of the paper wound thereon, an'
index on the roller and on the frame for spacing the lines on the paper, projections extending from the carriage, and a dog engaging the projections, which dog has a Vertical movement, producing an intermitting transverse movement of the carriage.
CHARLES W. WVALKER.
