SIGHT ATTACHMENT FdRTYPE-WRITERS.
Patented March 5,1907.
Application filed March 10.1906. Serial No. 305.393.
To all whom 71?- muy concern:
Be it known that I, JAMES BARTLETT IlAM- 5 MOND, a citizen of the United States, residing at New York city, New York, have invented j certain new and useful Improvements in Sight Attachments for Type-Writers, of
which the following is a specification.
My invention consists in a sight attachment for t e-writers, particularly that form known as t e Hammond, in which a key wheel or shuttle is employed in connection 'with a hammer and in which an inking-rib bon guide and a ribbon-shield are arran ed between the type and the hammer or t er part cooperating therewith.
The invention consists in the features, combination, and arrangement of arts hereinafter described, and particular y pointed out in the claims.
In the accompanying drawings, Figure l is a sectional view of so much of the type-writer I as is necessary to a complete understanding of my invention. Fi 2 is a detail view showing therel'ation o the hammer, shuttle,
and ribbon-shield. Fig. 3 is a further detail view of the ribbon-shield and means for holding it down in place. Fig. 4 is a detail viewv of the ribbon-guide. Fig. 5 is a lan view of the anvil, shuttle, hammer, an ciated therewith.
In these drawings the anvil 1, the hammer 2, and the shuttle 3 are of substantially parts asso ordinary and well-known form. The ribbon extends between s ools 4 and 5 in rear of the type on the shutt e, being guided by fingers 6 7, constituting a ribbon-guide, said fingers being carried byan arm 8, pivoted at 9 to the under side of the plate '10, which partly oncircles the anvil, said plate being supported I by posts, as at 11, from the frame 12. The ribbon- 'de arm 8 is curved to-eo'nform sub-- stantial y to the curved side of the anvil and shuttle, and there is one of these arms, together with its 'uide-fingers, on each side of the shuttle, as s own in Fig. 5. In rear of the ribbon .a shield 13 is arranged, supported at its ends, by pins or extensions 14 from the curved arms 15 which extend to the front of the machine and are pivoted at 16 to the frame part 10. These curved arms 15 over- .lie pro ections 17, extending vertically and thence horizontally'beneath the said arms- 15, said projections-or fingers being secured to or forming a part of the curved arms 8 of the ribbon-guide;
Normally the ribbon-guide, together with lie of printing and also to elevate the ribbonshield so that the opening 18 therein will come opposite the type to be printed and also the end of the hammer, I arrange on each side of the machine a vertically-extending rod 19, the lower endof which is bent at 20 v and rests upon a roller 21, carried by the space-frame 22 of substantially the-same form as is well known in-the Hammond machine. At their upper ends these rods bear against the under edge of the arms 8, so that when a key is depressed the vertical sliderods 19 will be operated and the arms 8 swung upwardly to lift the ribbon into the printing plane, and at the same time the fingers 17 will lift the curved arms 15, which will thereby raise the ribbon-shield to the proper position for printing, and as soon as the key is released these parts-41. e. the rib bon and ribbonshielddrop below the printing plane, and the last word or letter printed will be within clear view. It will be understood that the ribbonshield and its carrying-arms may be swung up out of the way when it is desired to adjust or inspect any of the parts around the printing-point, because the'arms 15 simply rest upon the fingers 17 A One of these fingers may be provided with an adjustable bearingpoint 23, Fig. 4, for the arm 15 to rest on,
so that the ribbon-shield may be adjusted vertically to its proper position. In order to hold the ribbon-shields down, I provide a re- .the said guide with the hook. When it is desired to swing back the arms 15 with the ribbon-shield, it is simply necessary to throw the alining-guide toward the-rightv to thus remove the hook 24 from over the shield-carrying arm 15, and then this 'may be thrown back. This hook may be adjustable, being pivoted at 30, Fig. 3, to the upwardly-extendmg part '31 of the alining-guide, a screw 32,
passing through a slot 33, serving to set the and comprising pivoted '2 5 shield,a pivoted support therefor, said supically as the keys are 0 erated to expose the.
printin to view, sai ribbon-shield being movab e independently of the guide, substantially'as described. I
2. In a type-writer of the class described, a
shuttle, aribbon-guide, a ribbon-shield carried independently of the guide, means for. raising and lowering the ribbon-guide as.
the keys are struck, the said ribbon-guide in turn causin the upward and downward movement 0 the ribbon-shield, substantially as described. I
3. In combination in a type-writer 0f the ciass described, a shuttle, a ribbon-guide movable substantially in a vertical plane arms, a .ribbonport resting upon a part of the pivoted arms 01 the guide and means for raising and lowering the guide-arms as the keys are operated, substantially as described r 4. In combination a type-writer of the class described, a shuttle, a ribbon-guide including pivoted. arms, a ribbon-shield, pivoted supporting means therefor resting on a part ofthe pivoted guide-arms, verticallymovablerods for raising the. pivoted supporting-armsand theIspace-frame for 0 erating the rods, substantially as describe '5. In'combination in a type-writer, a ribbon-guide, a ribbon-shield, a movable support therefor, means for raising the ribbon guide and shield as the keys are struck and a catch for holding-the movable support down,
substantially as descr'hed.
In testimony-whereof I affix my signature in presence of two witnesses.
