CLASS 15 #. GROUP

JAMES BARTLETT HAMMOND in NEW YORK.

Device for typewriters for lifting the ribbon sign and the ribbon guide in the print position.

Patented in the German Empire on March 31, 1906.

Hammond typewriters are known in which there is a difference between the Type and the Hammer a ribbon guide and a ribbon shield are provided, which are are usually located in a lower layer, but which are made possible by 'connections with letter keys are raised to print each time a key is pressed will.

ίο The purpose of the invention is to make the arrangement such that the ribbon shield is independent can be lifted off the ribbon guide, but that it is automatic Operation depends on the effect of the ribbon guide. This is achieved by making the ribbon shield arms independent are supported by the arms of the ribbon guides and that the upward movement for the ribbon label when pressing a key through vertical Rods is transferred to the arms of the ribbon guide, which itself again the Lift the arms carrying the shield, the latter being independent of the guide arms can be withdrawn.

In the drawing, Fig. 1 shows in section

the parts of a typewriter necessary to understand the invention.

Fig. 2 is a. Single view to show the position of the hammer, the wheel-shaped type carrier and the ribbon label.

Figure 3 is a downward view of the ribbon shield and assembly to keep in its position.

Figure 4 is a detailed view of the ribbon guide. ■

Fig. 5 is a plan view. of the anvil, the type carrier, the hammer and the with it connected parts. ·

According to the figures, the anvil 1, the hammer 2 and the type boat 3 have the usual, known shape. The color. band extends between reels 4 and 5 behind the types of the type carrier. The ribbon is passed through fingers 6 and J ₁ which are carried by an arm 8 connected at 9 to the lower edge of the plate 10. The plate 10 partially surrounds the anvil and is supported by supports 11 of the frame 12. The ribbon guide arm 8 is curved to substantially correspond to the curved side of the anvil as well as the type boat. A guide arm with the associated guide fingers is arranged on each side of the type carrier, as shown in FIG. Behind the ribbon, a shield 13 is carried at its ends by pins 14 of curved arms 15, see Figs. 1 and 5, which extend towards the front of the machine and are hinged at 16 to a frame 10. These arms 15 are above Approaches 17, which extend first vertically and then horizontally under the arms 15 and are connected to part of the curved arms 8 of the ribbon guide.

Usually, the ribbon guide and the ribbon label face away from

printed backwards so that the scribe can read the last line or the last line written Can see letters. This position of the parts is shown in FIG.

To lift the ribbon into the print position and the ribbon label so far above to lead that its opening 18 of the type to be printed as well as the hammer end comes to lie opposite is on each side

ίο the machine a vertically extending one Bar 19 is provided, the lower end of which is bent at 20 and on a roller 21

. rests that of the spacer frame 22 of substantially more common and well known Type is worn. At the upper ends of these rods lie against the lower edge of arms 8 in such a way that the vertical slide bars 19 moved when a key is pressed and the arms' 8 upwards be swung to bring the ribbon into the print position, at the same time the fingers 17 the curved arms 15 and with them the ribbon shield to the top Raise pressure position. If the button is released,

so the parts fall, d. H. the ribbon, the ribbon label, back under the pressure point and the last word printed, or the last, letter is. visible.

It can be seen that the ribbon shield, as well as the support arms, swung upwards can be, if so desired, to any parts around the pressure point around because the arms 15 rest on the fingers Ί 7. One of those fingers can be provided with an adjustable stop 23 (FIG. 4) on which the arm 15 rests in such a way that the ribbon shield can be set vertically into its correct position can. To hold the ribbon shield downward, a retaining hook 24 is on one of the Alignment stops 25 attached for the line lines, which extend from the frame part 10 the machine. The guide from which the hook is carried is at 26 rotatably connected to the frame part 10 and is by a spring 27 in the normal position obtain. A leading through a slot 29 screw 28 limits the position of the Aligning fence with the hook. If you want the arm 15 with the ribbon label To swing backwards, you only have the directional stop 25 according to FIG. 5 to the right to push and the hook 24 out of the path of the swingable carrying the ribbon sign Arm 15 to remove, whereupon this can be swung. The hook can can be made adjustable and is at 30 (Fig. 3) on the upwardly extending ones Part 31 of the alignment stop hinged. One. Screw 32 goes through a slot 33 and serves to set the hook in the desired position. Of the. So hook serves to precisely determine the effective height of the ribbon shield.

Claims (2)

Patent-to sayings: 1. Device for typewriters to lift the 'ribbon shield and the ribbon guide in the print position when pressing the letter keys, thereby, characterized in that arms (15) of the ribbon shield (13) are independent of the Arms (8) of the ribbon guide are pivotably mounted and that the upward movement of the ribbon shield when pressing a key down through vertical rods (19) on the "arms of the ribbon guide is transmitted, which itself again the arms carrying the shield to lift. 2. Apparatus according to claim 1, characterized in that a foldable Stop (24) is provided on a fixed part of the machine to reduce the stroke of the ribbon shield to limit the carrying arm upwards. : 1 sheet of drawings.
