UNITED STATES ATENT QFFICE.
OTTO A. HOKANSO'N, OF WOODSTOCK, ILLHJOES, ASSIGNQR TO WOODSTOCK TYPEWRITER COMEANY, OF "WOODSTOCK, ILLI'HQIS, A. CORPORATION OF ILLINOIS.
TYPE-BAR GUIDE.
Application filed February 18, 1922. Serial No. 537,444.
T 0 all whom it may cancer-n.
Be it known that I, OTTO A. HoKANson, a citizen of the United States, residing at W'oodstoclr, in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in Type-Bar Guides, of which the following is a specification.
This invention relates to guide mechanism for accurately directing the stroke of a type bar at the time that the bar engages the .paper carried by the typewriter platen.
The invention has for its object the provision of a guide of the class named which shall be of improved construction and operation, and which shall be readily and accurately adjustable.
The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawing and described in the following specification, and it is more particularly pointed out in the appended claims.
In the drawing Fig. 1 is a front elevation of a portion of a typewriter showing one embodiment of the present invention applied thereto;
Fig. 2 is a top plan view of the mechanism shown in Fig. 1;
Fig. 3 is a horizontal section on line 33 looking upwardly; and
Fig. at is a perspective view of a detail of construction.
In the drawing, the numeral 10 designates a typewriter platen, and 11 designates a portion of a type bar segment positioned below and in front 01" the platen 10 and provided with a plurality of type bars 12 which swing upwardly and rearwardly to strike the platen 10. Carried by the type bar segment 11 is a type bar guide supporting plate 13 having an opening 14 therein to permit the scale 15 to be visible, there being index points 17 and 18 to indicate the writing position along the scale 15.
The plate 13 is provided with dowel pins 19 which project forwardly through the segment 11 and screws 20 extend through the segment 11 into the plate 13 to securely hold the plate 13 in place. The plate 13 is provided with a pair of upwardly projecting bracket members 21 which carry torwardly projecting L-shaped supports 22.
It will be apparent that rotation 01 the screws 29 will positively move the plates 23 for adjustment on their supports, the direction of movement depending upon the direction of rotation of the screws. The inner edges of the plates 23 are provided with rearwardly converging curved flanges 31, the rear ends of which project between the brackets 21 and form stops for the outward movement of the plates 23 and their guide flanges. It will be apparent that the plates 23 and their guide flanges 31 may be adjusted to vary the width of the opening between them and that they may both be adjusted either to the left or right to properly position the guide opening between them relative to the printing point of the type bars. These adjustments are accomplished without changing the angular position of the guide flanges relative to one another, or to the platen. Since the plates are moved by threaded members, adjustments may be very accurately made and when completed the parts are firmly held in place by the locking screw 24.
I claim 1. A type bar guide comprising asupport, a guide member mounted on said support, a threaded device for shifting 821d guide member in two directions of ad ustment on said support, and a separate looking device for retaining said guide member in various adjusted positions.
2. A type bar guide comprising a pair of horizontally arranged plates having flange guides on adjacent edges thereof, a support for each of said plates, a threaded device for shifting each. of said plates on its support, and a screw for locking each of said plates in various adjusted positions on its support.
3. A type bar guide comprising a pair of spaced supports, plates slidably mounted on said supports having flange' guides on adjacent edges thereof, screws having circumferential grooves therein threaded in said supports, and flanges on said plates engaging said grooves for moving said plates when said screws are turned.
4. A-type bar-guide comprisingapair-of spaced supports, plates slidably mounted on saidsupports and having spaced flange guides on adjacent edges thereof, screws threaded insaid supportsand engaging said plates for shiftingsaid plates in opposite directions on their supports, and locking screws for fixing said plates in adjusted positions on said supports.
5. A- type bar guide comprising a pair said platen, horizontally arranged plates mounted on said supports, said plates having converging guide flanges on adjacent edges thereof, threaded members for adjusting said plates in the direction of the axis of said platen independently of one another, guides for preventing angular and front and rear movements of said plates, and screws for locking said plates in adjusted positions.
7. The combination with a typewriter platen, of a pair of spaced supports-positioned in front of said platen each of said supports having a horizontally and a vertically arranged flange, a' piate slidably mounted on each of said horizontally; arranged flanges, converging type bar guides carried by adjacent edges of' said plates, screws extending through elongated'sl'ots in said plates and engaging said horizontally arranged flanges for locking'said plates in position on said flanges, screws threaded in the vertically arranged-flanges of said sup-- ports, and lugs on said plates engaging said last-mentioned screws to cause said plates to move in unison with said last-mentioned screws for adjusting the guiding members of said plates in the direction of the axis of said platen.
In testimony whereof I have signed my name to this specification on this 16th day of February A. D. 1922. v
