To all whom it may concern: a I
Be it known that I, ALFRED G. F. narrow- SKI, a subject of the German Empire, residing in Brooklynborough, in thecounty of Kings, city and State of New York, have invented certain new andv useful Improvements in Type-Writing Machines, of which the following is a specification.
This invention relates to typewriting machines and more particularly to means for locking the printing mechanism of the machine against unauthorized operation. N
The means for holding the printing mechanism inoperative may comprise bar which may be passed through an openingin the frame of the machine and across the machine directly beneath the key levers, and then projected through an opening at the other side of the machine.
The bar has a flange at one of its ends adapted to catch against the outside of the .frame of the machine, since said flange or fluke is too large to go through the opening in the machine base through which the bar passes. This bar may at its other end extend through the base at the opposite side of the machine, and may be sealed'by a oad lock having its staple extending through a hole in the end portion of the bar extending from said other side of the machine frame. The padlock itself is too large to go through the opening in the machine base. The bar cannot be removed from the chine except by unlocking and withdrawing the pa'dlock, for the bar is prevented from moving in one direction by its flange and in the other direction by the padlock.
Other features and advantages will hereinafter appear. In the accompanying drawings, Figure 1 is a side elevation of an Underwood typewriter showing my invention as applied thereto. v Fig, 2'is' a fragmentary perspective view, showing the baras rendering the printing mechanism inoperative, the bar being locked to the machine. Fig. 3 is a perspective view of the locking bar. a
In the Underwood typewriter, keys 1 are connectedto type-bars 2 through interponation with prlnting mechanlsm' comprising nents 3 to cause the types t to print characters on a work-sheet carried by a platen 5.
In order to holdthe keys land typebars 2 locked against operation, a wooden bar 6 may be passed through theu'sual opening? in the frameS of the machine, beneath the keys 1 and out through a similar opening 9 in the'other side of the machine; The bar 6' rests on the lower edges of the openings, and fits snugly beneath the keys 1 thereby effectually locking the latter. It has at one end a fluke or barb in the form of a flange 10 extending from a metal band 11. The flange 10 lies against the outside of the frame 8 when the bar 6 is in positiom To prevent the other end of the bar 6 from being drawn throughthe machine, it
'is' provided, at a portion extending out of the opening 9 in the opposite portionof the frame 8, with a hole 12, through which the staple 13 of an ordinary padlock may be passed. The staple seals the bar 6 locked in the machine, being too large to pass through the opening 9. The padlock may 'be unsealed or opened by a key, and the staple withdrawn, and the bar drawn out of type-bars and keys for operating said typebars, of a bar in position to hold said print ing mechanism against operation, said bar movable lengthwise into and out of said holding position.
2. In a typewriting machine, the combination with printing mechanism comprising type bars and keys for operating said type bars, of a bar to hold said printing mechanism against operation, said bar movable in the direction of its length and thereby removable from the machine, and means to lock the bar in the machine in position to hold the printing mechanism against operation.
3. In a typewriting machine, the combitype-bars and keys for operating said typebars, of a bar extending transversely of the machine beneath the keys and adapted to hold said keys against operation, said bar movable in the direction of its length to re lease the keys, and means for preventing the removal of said bar comprising a fluke or barb at one end of the bar, and a lock at the other end of the bar.
4. The combination with a frame and a key-lever mechanism contained therein comprising a set of key levers ranged across the frame, said frame having openings in its opposite sides, of a locking bar extending transversely of the frame and key levers beneath the key levers to lock the latter, and projecting through said openings and supported directly by the frame at said openings, said bar arranged to be withdrawn lengthwise to release the key levers.
5. The combination with a frame and a key-lever mechanism contained therein comprising a set of key levers ranged across the frame, said frame having openings in its opposite sides, of a locking bar extending transversely of the frame and key levers beneath the key levers to lock the latter, and projecting through said openings and supported directly by the frame at said openings, said bar arranged to be withdrawn lengthwise to release the key levers, and means to seal the locking bar against removal.
6., The combination with a frame and a key-lever mechanism contained therein comprising a set of key levers ranged across the frame, said frame having openings in its .opposite sides, of a locking bar extending across the frame and key levers directly beneath and close to the key levers to lock the latter and extendinginto said openings and supported by the frame at said openings, said bar movable lengthwise to withdraw it from beneath the key levers, and means to seal said locking bar against manipulation or withdrawal.
7. The combination with a frame and a key-lever mechanism contained therein comprising a set of key levers ranged across the frame, said frame having openings in its opposite sides, of a locking bar extending across the frame and key levers beneath and close to the key levers to lock the latter, said bar being of a form to rest upon the edges of the openings in the frame, and to fit under the keys to prevent manipulation of the latter, said bar movable in the direction of its length to withdraw it from the frame.
8. The combination with a frame and a key-lever mechanism contained therein comprising a set of key levers ranged across the frame, said frame having openings in its opposite sides, of a locking bar extending across the frame and key. levers beneath the key levers to lock the latter, said bar extending through said openings and being of a form to rest upon the edges of the openings, and to fit under and close to the keys to prevent manipulation of the latter, said bar having at one end a fluke or'erossepiece to prevent it from being drawn through the adjacent opening and having at the other end a padlock too large to go through the other opening in the frame.
9. The combination with a frame and a key-lever mechanism contained therein comprising a set of key levers ranged across the frame, said frame having openings in its opposite sides, of a locking bar extending across the frame and key levers beneath the key-1evers to lock the latter, said bar extending through said openings and being of a form to rest upon the edges of the openings, and to fit under the keys to prevent manipulation of the latter, said bar having at one end a fluke or cross-piece to prevent it from being drawn through the adjacent opening, and having at the other end a projection provided with an opening in which is inserted the hasp of a padlock, said padlock being too large to go through the other opening in the frame.
