To all whom t 'may concern:

Be it known that l, RICHARD ivi. BECKER, a citizen of the United States, residing in Brooklyn borough, city of New York, in the county of Kings and State of New York, have invented certain new and useful llmprovements in Combined Type-VVriting and Computing Machines, of which the following is a specification.

My invention relates to combined computing and writing machines, and especially to devices ada ted to prevent the types from striking the p aten, as, for example, to prevent printing during computation. Certain features may bensed in typewriting machines to prevent printing whenever desired, as when the .end of a line has been reached, etc. f

A feature of the'invention is the provision of means for shifting the platen at any time into and out of the range of the types, for

with which it has a may have a shiftable connection with the 'machine frame, permitting the platen to be shifted toward and from the printing point. Blocks fixed to the machine frame may eX tend into slots formed in the guide rail, permitting the guide rail, and with it the earriage, to be. shifted in a forward and rearward direction. The shifting movement may be effected by means of a shift rod eX- tending longitudinally through the guide rail, which for thatA purpose is in the form of a tube or sleeve, said rod carrying pins working in cam slots in said blocks so that as the rod is moved longitudinally in the rod and sleeve are at the same shift the platen.

The movement of the rod may be effected by a non-print key on a collar or ring journaled on the rod between the end of the guide rail and the head on the rod, said rod longitudinally when the key is actuated.

Other features and advantages will hereinafter appear.

In the accompanying drawings, which illustrate a form of the invention applied to an Underwood-Hanson combined typewriting and adding machine,

Figure 1 is a part sectional end elevation View of a being shifted to non-printing position.

Fig. 2 is a ,fragmentary end elevation showing the non-print key shifted to normal position for printing.

Fig. 3 is a part sectional view` showing the carriage guide rail and the shifting rod therein, the parts being in the position indicated by Fig. l.

Fig. Al is a similar View, but with print key shifted to the Fig. 2 position.

Fig 5 is a perspective view of the mechanisni shown in F ig. 3.

Fig. 6 is a part sectional plan View showing the adjustable connection between the guide rail and the machine frame.

The rotary platen l is mounted in a frame Q on the carriage 3, the platen shaft having bearings in arms et pivoted at 5 to the carriage, so that the platen may be shifted to upper and lower case positions. Type-bars 6 pivotcd on a rod 7 in a type-bar segment 8, carry upper and lower case types 9 and l0, adapted to be brought to printingI position at the front of the platen when the ty-pebars are swung upward to the full line position' in Fig. l, the platen being,r normally in the dotted line position. The type-bars are actuated by keys l1 comprisingl levers l2 fulcrumed at 13 and connected by bell cranks lll: to the type-bars.

The numeral keys lla in the form of machine hcrein shown are provided with pend ants l5 which strike bell cranks l5a to set up on computirngr mechanism (not shown) the numbers represented by the keys struck. lf it is desired to set up numbers without printing on the platen, or for any other purpose to actuate the type-bars without permitting; them to strike the platen, the latter is shifted rearwardly to the full-line position, l? l, out of range of the type-bars, which, when swung u'pward, strike a stop 16 on the seg-- ment S. The stop 1G positively limits the .movement et the types except for a slight ltion with blocks li) which be Xed in portion of the machine, the platen.

- the rod 22.

the usual way to each end of themachine frame 20, and which form a support for the rail 17 and the carriage. These blocks may be der to shift the tube 17, and with it the carriage', a rodl 22 extends through'the tube and has a limited longitudinal movement therein, permitted b y slots 23, -through which the blocks 19 extend. Guide pins 24,t

fixed in'v the rod 22, extend through cam slots 25 in the blocks 19. When the rod 22 is shifted longitudinally in each end of the sleeve 17 (see Figs. 3 and 4) the pins 24 working in the slots 25cam the sleeve 17 and with it the platenina forward or rearward direction, the slots 25 being of such width as to prevent any movement. of the sleeve 17 independently of the movement of The inclination of the slots 25 to the direction of the rod 22 is preferably insufficient to permit forward or rearward pressure on the guide rail 17 to produce a tension between the guide rail and rod in the direction of their length, so that the guide rail and carriage are dsitivelv held against forward or rearward movement.

The shifting rod 22 is shifted by means of a key 26 fixed to a collar 27 loose on the rod, and interposed between one end of the sleeve 17 and a head 28 on the end of the rod 22. The collar 27 comprises sections 2 9 f along the slot 25 during such movement,

forces the rod 22, and with it the sleeve 17 rearwardly, thus moving the platen away from the printing position.

A coil spring 32 mounted on the left-hand end of the rod 22, bears against the end of the sleeve 17 and a head 33 on the rod 22, so that when the platen is shifted rearwardly, the spring is placed under compression, and so acts automatically to return the parts to normal position when the key 26 is returned. It will be noted that when theplaten isshifted to the rear, the sleeve 17 is positively held 'in shifted vposition Iby the collar 27, the wide section 29 thereof bearing squarely against the sleeve so there is no tendency of the spring 32 to accidentally return the sleeve. Also, the inclination of 4the slots 25 is such that the forward or rearpositively locked in both printing and nonprinting positions.

In assembling the parts-either

head

28 or 33 of the rod 22 may be secured to the rod after the tube 17, collar 27 and spring 32 have been assembled on the rod. The pins 24 may be inserted in the rod through openings 24u in the tube 17, said openings being afterward plugged, if desired.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
