SPECIFICATION forming part of Letters Patent NO. 625,616, dated May 23, 1899.
Application filed December 29, 1896. Serial No. 617,364. .(No model.)
To all whom it may concern:
Be it known thatl, RICHARD W. UHLIG, a resident of New York, (College Point,) in the county of Queens and'State of New York, have invented certain new and useful Improvements in Type-VVriting Machines; and I do hereby declare the following to be a fu11,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.
My invention relates to an improvement in type-writin g machines, and more particularly to improvements on the carriage and devices carried thereby, one object of the invention being to provide simple and efficient `paper carrying and feeding mechanism.
A further object is to construct the carriage of a type-writing machine in such manner that a portion of the carriage can be easily raised to permit the last line of writing to be readily seen by the operator.
With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a perspective view with a part of the guard broken away. Fig. 2 is a cross-section. Figs. 3 and A are end views. Fig. 5 is an elevation with the hinged portion of the carriage raised. Figs. 6 and 6 are detail views. Fig.. 7 is a view of a modication.
My improvements are intended more particularly for use on type-writing machines of the type-wheel class.
My improved carriage comprises two parts A B, the part A being constructed to slide on the frame of the machine and is provided with a ratchet-bar 1 to be engaged by the ratchet feed mechanism. (Not shown.) The part A of the carriage is provided at its ends in line with the rear edge with perforated lugs 2 2 for the accommodation of a rod 3, which latter also passes through end plates 4t 5 of the part B, whereby to hinge the latter to the part A, and thus permit the part B to be raised to facilitate the reading of the last line of writing, the paper carrying and feed mechanism being mounted on the said hinged part B of the carriage.
A rubber-covered feed-roller 6 is mounted between the plates 4 5 of part B of the carriage, one of the journals of said roller being extended beyond its bearingfor the reception of aknob 7. Asmaller feed-roller S is disposed at one side of the roller G, and its journals 9 are mounted in elongated slots or bearings 10 in the end plates 4 5. A paper carrying or retaining roller 11, preferably of wood and of greater diameter than either feedroller,is disposed at the other side or in rear of the feedroller 6 and is provided with journals 12, mounted in elongated slots or bearings 13 in the end plates. The rollers 8 and 11 are yieldingly impelled toward the feed-roller 6 by means of springs 14., located at the respective ends of the carriage and connecting the journals of said rollers 8 and 11. In order to facilitatel the turning of the paper-supply roller 11 when the paper is being wou nd thereon, one of the journals of said roller is provided with a knob 15. A bar 16 is located between the feed-rollers and secured at its ends to the end plates 4 5. This bar serves to support a guide 17, which can be conveniently made of a single piece of sheet metal so bent as to cause one edge to be disposed in close proximity to the smaller feed-roller 8 and its other edge to Y be disposed between the rollers 6 and 11 and partially embrace the former.
From this construction it will be seen that when the end of a sheet of Apaper is placed between the feed -rollers and the roller 6 turned by means of the knob 7 the paper will be drawn between said feed-rollers, and as the turning of the roller 6 is continued the paper will be directed partially around it by the guide 1,7 and Will thus be delivered to the supply-roller 11. The paper will be guided around the roller 11 (which latter may now be turned by the knob 15) by means of a series of spring-fingers 18, supported by a rod 19, mounted in slots 19a in the end plates 4 5 of partB of the carriage. (See Fig. 2.) Instead of the spring-metaliingers 18 rubber' bands 20 (see Fig. 7) may be used for causing the paper to properly wind on the roller 11, in which case vthe rubber bands will be supported by rods 21, mounted between the end plates 4 5.
The journal of the feed-roller 6, which is mounted in the end plate 4, is extended beyond the outer face of said plate and provided at its extremity with a ratchet-wheel 23. A lever 24 (approximately L-shaped and having both arms curved) is loosely mounted on said journal of the roller 6. The lower arm a of lever 24 is made with a socket l) for the reception of a small coiled spring c, and the wall of said socket is made witha small socket d forthe reception of one end of said coiled spring. The bottom of the springsocket I) is screw-threaded for the reception of the screw-threaded end of a pin e, by means of which a dog fis pivotally connected with the arm a of lever 24. The pivoted end of the dogf is also made with a socket g for the reception of the coiled spring c and also with a small socket h for the reception of the end'of said spring. From this construction it will be seen that the spring c tends to force the free end of the dog into engagementwith the ratchet-wheel 23; but it is desirable that .the dog .be held normally out of engagement with the ratchet-wheel, so that the feed-roller 6 can be readily and freely turned during the act of inserting or removing a sheet of paper into or out of the machine without the annoyance of the clicking sound caused by the dog riding over the teeth of the ratchet-wheel.
ln order to maintain the dog normally out of engagement with the ratchet-wheel, the dog is provided with an inner cam-face t', which will be engaged by a pin j on the plate 4, so as to move the dog away from the ratchetwheel, when the lever 24 returns to its normal position by means of a spring 25, one end of which is attached to the arm b of said lever andthe other end to a pin projecting from the plate 4. The lever 24 is prevented from being pulled too far by the spring 25 by means of the engagement of a tooth 7o on the arm b of said lever with a pin or stop Z on the plate 4. The pin Zalso serves as a guide for a slotted l bar 26, said bar being also guided by another pin 27 and is provided at its upper end with a thumb-piece 28, by means of which Vit can be readily depressed. The lower end of the bar 26 is cut away, as at 29, so as to permit the engagement of the toot-h 7c with the pin Z. From this construction it will be seen that when the bar 26 is depressed by the operator its lower end will engage the arm b of lever 24 and turn said lever on its fulcrum, thus moving the dog f away from the pin j, so as to permit it to engage the ratchet-wheel and rotate the same and the feed-roller 6, the movement of the lever 24 being limited by the engagement of a shoulder 37 thereon with the sliding bar 26.
When the slotted bar 26 is depressed, mo-
tion will be imparted, as above explained, to
the feed-roller 6. The end of the paper wound on the paper-supply roller will project upwardly between the rollers 6 and 8, so as to be held by the pressure of said rollers toward each other, and thus when the roller 6 is rotated motion will be imparted to the roller 8 in the opposite direction, and the two rollers will act to draw the paper from the roller 11, so as t0 cause it to be fed upwardly and permit it to pass overthe paper-guard C. My improvements are designed more particularly for use with a type-writing machine of the wheel7 class, and hence the paper as it passes upwardly from the feed-rollers will be disposed between the type-wheel and hammer of the machine. The extent of feed of the paper when the bar 26 is depressed is limited for double lines by engagement of a pin 30 on said bar with the lower end of slot 31 in the end plate 4.
In order to provide means whereby the paper can be fed a single line at each depression of the bar 26, I provide a pivoted arm 32, having a shoulder 33, which can be disposed in the path of the pin 30, and thus limit the downward movement of the har 26. The pivoted arm 32 is made with an elongated opening 34, through which a rod 35 of the carriage passes and serves to limit the movements of said pivoted arm.
The usual paper-guard C is attached to a rod 36 of the carriage.
The reason for hinging the upper part of the carriage is not to permit access to the paper for erasing, dac., as in bar machines, but merely to allow the operator to more readily see the last line of writing. It is therefore only necessary thatthe upper portion of the carriage have a slight movement, and the extent of this movement will be limited by means of a stop 38. The stop 38 is made in the form of an arm attached to one part of the carriage and having shoulders 40 and 4l to engage a pin 42 on the other part of the v carriage. Vhen the shoulder40 is in engagement with the pin 42, the two parts of the carriage will be locked together; but when it is desiredto View the last line of writing the stop-arm 38 may be moved slightly, (limited by a pin 43,) so as to disengage it from the pin 42, and then the upper part of the carriage can be raised, its upward movement being limited by the engagement of the shoulder 4l with the pin 42. The stop-arm 38 will be constantly impelled toward the pin 42 by means of a weight 44, projecting at an angle from the pivoted end of said arm 38.
My improvements are simple in construction and effectual in all respects in the performance of their functions.
Slight changes might be made in the details of construction of my invention Without detherefrom on its hinged connection with said base-frame, a latch pivoted to the base-frame and having two shoulders and a pin on the upper frame to be engaged by said shoulders.
