SPECIFICATION forming part of Letters Patent N 0. 456,025, dated July 14, 1891. Application filed December 4, 1890- Serial No. 373,565- (No model.)
To all whom it may concern:
Be it known that I, JOE L. EDLAND, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Typeriting Machine, of which the following is a full, clear, and exact description.
My invention relates to improvements in type-writing machines; and the object of my invention is to produce a type-writer of few parts which is specially adapted for private use, and which may be easily and correctly operated by one who is not familiar with type-writing. I
To this end my invention consists in certain features of construction and combinations of parts, which will be hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, 1n which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan view of the type-writer. 2 is a plan view with the dial removed. Fig. 3 is a vertical cross-section on the line 3 3 of Fig. 4. Fig. 4 is a broken vertical longitudinal section on the line 44. of Fig. 3; and Fig. 5 is a side elevation, partly in section, of the type-writer.
The machine is provided with a suitable base A, which is adapted to rest upon atable or other object, and a carriage B is mounted longitudinally on the back side of the base so as to slide thereon, the carriage having a flat lower portion which moves in keepers C on the base, and having on its inner side a rack B, which is engaged and moved by a spring-pawl in a manner hereinafter described, the notches on the rack corresponding to a letter-space, so that by moving the rack and carriage one notch at a time the proper spaces will be made on the paper. A rubber roll D is mounted longitudinally in the carriage, the roll serving as a feed-roll and as a printing-platen, and one end of the roll has a thumb-piece D fixed thereto, by means of which the roll maybe revolved,and the roll is also provided at one end with a ratchet-wheel d, which is engaged by a pawl d, pivoted on the carriage beneath it and held in engagement with the wheel by a spring (P, so that the roll will be thus prepropriate character.
vented from turning back in the wrong direction. The front upper portion of the roll D is clasped by flat springs E, which are secured to the carriage and press lightly against the roll, said springs being adapted to hold the paper e upon the roll and at the same time to allow it to be fed between the springs and the roll. I
A drum F is fixed centrally to the base A, the drum having a flange F at the bottom to enable it to be easily secured to the base and having its rear portion cut away, as shown at F so that said rear portion of the drum may overlap the carriage and roll and bring the type in line with the roll, as described below. The drum F isinclined forward, as best shown in Figs 3 and 5, so that'all the characters on the dial which surmounts the drum can be easily and distinctly seen.
Thedrum is provided at the top with a three armed spider G, which serves to strengthen the drum and also affords means for securing some of the Working parts of the machine, and a cross-arm G extends centrally through the drum near the lower part thereof, the cioss-arm and spider both being centrally perforated to receive a verticallymovable shaft, as described below. The drum F is surmounted by a dial H, which has a notched flange I-I around its outer edge, and which has the various characters to be printed inscribed around its outer portion near the flange, its characters being preferably arranged With the upper-case characters next the flange and the lower-case'just within the uppercase and with the letters of the upper and lower-case alternating. The notched flange 11 serves as a guide for the printinglever and causes it to descend above the ap- I is mounted vertically in the central portion of the spider G and dial H, the said tube havinga vertical slot 2' near the top and having alaterally-extending arm I beneath the slot and above the dial, said arm terminating in vertical lugs i, between which is pivoted the printinglever J, said lever having at its outer end a handle J, by which it may be operated, and having its inner end connected with the vertical shaft K, which extends downwardly through the tube 1. The tube I is held in place by a key 7', which fits in recessest' on IOC opposite sides of the tube just beneath the spider G, and in the central portion of the tube on opposite sides are slots to receive the pin j, which extends through the shaft- K and to permit the pin to move vertically with the shaft. The shaft K is normally pressed downward, so as to raise the handle of the printing-lever by a spring 70, one end of which is fixed to the base A and the opposite end of which is made to enter between the two parallel flanges 7c on the bottom of the shaft K.
Fixed to the lower end of the tube I is a hub L, which will necessarily revolve with the shaft. The hub L is provided with a Wide flange L, extending laterally and ciroumferentially from it and fixed to the flange is an annular plate M, the outer portion of which is slit radially to form theflexible typefingers M, which carry type upon their under sides near the outer ends, the type representiug characters similar to the characters on the dial H, and the type beingarranged for upper and lower case printing by producing the upper and lower case type on alternate fingers.
A sleeve N is mounted to move vertically 'on the tube 1, and the sleeve is held to the shaft K by the pin j, which extends through the shaft and sleeve and through the slots i in the tube 1. The sleeve will thus move vertically with the shaft and will revolve with the shaft and tube.
Pivoted between the depending lugs O, on the under side of the spider G, is a curved lever O, the outer end of which extends to a point above the outer edge of the plate M and the inner end of which is slotted horizontally, as shown at 0, so as to clasp loosely the annular flange N on the sleeve N. It will thus be seen that when the sleeve is raised the inner end of the lever 0 will be raised and the outer end will be forced downward, thus depressing one of the type-fingers M and causing a, character to be printed on the paper e immediately below said finger.
On the inner sides of the drum F are pivoted ink-rollers P, which are thus brought within the path of the type on the fingers M, so that the type will be kept well inked.
The dial-plate H is provided on one side with a depending ear Q, the lower end q of which is bent outward, so as to engage the upper arm of the elbow-lever R, which is pivoted to a boss 0" on the flange F of the drum, and the lower arm of which terminates in a thumb-piece R. The plate H has a depending pin q, and is pressed upon by a spring S, which is secured at one end to the under side of one of the spider-arms, as shown at sin Fig. 2, and has a central coil, as shown at S, to give it the necessary strength, and its free end presses against the pin q of the dialplate, the pressure of the spring normally holding the dial in position for lower-case rinting.
hen the dial is to be shifted and the mechanism is to print with upper-case type, the operator depresses the thumb-piece R, and this will cause the lever B to strike ear Q, and move the dial I'l against the spring S, so as to shift the mechanism just enough to bring it into position to print upper-case characters. The type-fingers bear upper and lower case type to correspond with the characters on the dial, the upper and lower case type being arranged on alternate fingers, and by moving the dial, as described the dial characters will be made to align with either the upper or lower case type, and 11] order that there may be no mistake the dial movement is limited to the distance from one typefinger to another. An elbow-lever T is pivoted on the base A Within the drum F, the said lever being pivoted at its elbow so that one arm will extend to a point adjacent to the rack B of the carriage, and pivoted on p the end of the lever next the rack is a pawl T, which is normally held in engagement with the rack B by a spring t, extending from the elbow of the lever T to the rear portion of the pawl. The inner arm of the lever T has a vertical recess t in it near one end to receive the lower end of the elbow-lever V, said lever being pivoted between the lugs Y, which depend from the cross-arm G, and the upper arm of the lever V enters between the flanges 7c of the shaft K. It will thus be seen that every time the printing-lever 1s depressed and the shaft K raised to print a character, as described above, the elbow-lever V wlll be tilted, thus tilting the elbow-lever T and drawing back the pawl T and when the printing-lever is raised and the above movements reversed the pawl T will move the rack B and carriage B the distance of one notch, and as the notches correspond with the letter-spaces the spaces will be properly made on the paper.
A lever WV is centrally pivoted on the base A within the drum F, the inner end to of the lever pressing against the rear end of the pawl T and the outer end of the lever belng made to extend through a slot f in the bottom of the drum F and terminating in a thumb-piece W. It will thus'be seen that by tilting the lever W the pawl T may be thrown from engagementwith the carriagerack 13, and while the lever and pawl are held in this position the carriage may be moved freely back and forth and brought into a desired position.
To operate the machine,a piece of paper 9 is made to enter between the roll D and springs E from the rear under side, and the operator then grasps the handle J of theprinting-lever and brings the lever opposite the letter to be printed. This brings the type representing the letter above the paper 6 and printing-roll D, as the plate M bearing the type-fingers is arranged in relation to the lever J, so that when the lever is above a certain letter the type representing the said letter will be above the printing-roll. The op IOC leasing the pawl T from the carriage-rack,
and the carriage is then moved back into position for printing another line, the roll D being first turned up the distance of onelinespace by means of the thumb-piece D.
From the foregoing description it will be seen that the type-writer is composed of comparatively few pieces, and that consequently it cannot easily get out of repair, and it will also be observed that any one who can read can run the machine, as all that is necessary to print upon the paper is to insert the paper in its proper place, bring the lever J above the characters to be printed, and then to press the lever.
