Application led January 28,1920. Serial No. 354,881.

To all whom it may concern Be it known that I, JOHN WALDHEIM, a. citizen of the United States, residinr in Elizabeth, in the county of Union and tate of New Jersey, have invented certain new and useful Improvements in Combined Typewriting and Computing Machines, of which the following is a. specification.

This invention relates to combined typewriting and computing machines, and isillustrated in connection with improvements disclosed in the condin applications of Henry L. Pitman, erial o. 186,098, tiled August 14, 1917, (now Patent No. 1,345,460, dated July 6, 1920) and Serial No. 176,676,

filed June 25, 1917 (now Patent No. 1,360,'

145, dated November 23, 1920).

In 'the first-mentioned application, one or more column-totalizers are connected with the typewriter carriage to travel therewith through computing zones, and a cross-total izer is provided which may be made to travel through computing zones with the t pewriter carriage by means ofsuitable pic -up devices. In the second-named application, punctuation-skipping mechanism controlled by a column-totalizer is disclosed.

ln carrying out the present invention, the machine, provided with column-totalizers and a cross-totalizer, is also provided with a punctuation-skipping mechanism which may be controlled by a column-totalizer. Usually the cross-totalizer iS caused to travel through a com uting zone with a columntotalizer, and t e punctuation-skipping for both the column-totalizer and the cross-total izer may be effected by the column-totalizer. Them however, the cross-totalizer is carried through a computing zone without a column-totalizer, the punctuation-skipping means will be ineffective unless some other means is provided. For this purpose, provision may be made of means whereby the punctuation-skipping means may be controlled by the cross-totalizer when passing through a computing zone.

Other features and advantages will here inafter appear.

In the accompanying drawin s,

Figure l is a side view of an lnderwood addendagra h machine, showing my invention applied thereto.

Fig. 2is a detail front elevation of the typewriter escapement mechanism, showing the same in. its usual position set for single letter-space movement of the carriage.

Fig. 3 is a skeleton perspective of the punctuation-skipping mechanism showing the connections whereby said punctuationskipping mechanism may be controlled by either a. column-totalizer or a cross-totalizer.

F ig. 4 is a rear elevation, showing means whereby the cross-totalizer can be carried through 'a computing zone with the typewriter carriage and released when the passa e through the zone has been completed.

ig. 5 is a horizontal view, showing -the feelers by means of which the punctuationskipping mechanism may be operated by either the column-totalizer or the cross-totalizer.

Upon depression of character-keys, not shown, type-bars 1 will be swung upwardly and rearwardly to cause types 2 thereonto strike against a platen 3 revolubly mounted by means of an axle 4 in a typewriter carriage 5. Said carriage 5' is mounted for movement across the machine by means Vof a roll 6 at the front thereof, lying in a groove in a rail 7 of the frame, and at the rear by means of a rail 8, and is urged toward the left of the machine by means of a strap 9 and spring-drum 10.

Movement of the carriage 5 to the left, under the influence of said strap 9 and spring-drum 10, is controlled by means of escapement mechanism comprising a rack 11 pivotally supported on the carriage 5 by means of arms 12 and normally in mesh with a pinion 13. Said pinion 13 has a one-way driving connection with the escapement wheel 14 by means of pawls 15 and springs 16 thus enabling the typewriter carriage to be returned to the right without reverse rotation of the escapement wheel. When each type-bar approaches the end of its printing stroke, a heel 17 thereon is brought into engagement with a curved universal bar 18 forming part of a frame 19 supported at the rear on pivoted arms 20. The frame 1i) is then moved to the rear and aetuates the usual dog-rocker 21, so as to throw the loose dog 22 out of engagement with the escapement wheel, and to bring the fixed dog 23 into e agement therewith. As soon as .the loose og 22 passes out of engagement with the escapement wheel, it is swun to the left by spring 24 to a position determlned by devices to be'describedhereinafter.

Upon return of the type-bar to its normal position, the frame 19 will be drawn to the front by any suitable means, not shown, and the dog-rocker will return to its normal position, under the influence of the spring 24, thus bringingthe loose dog ain into engagement with the escapement w eel, which, under the influence of the springdrum 10, will move the loose dog to its righthand limiting position against the action of the spring 24.

The typewriter carriage is connected by means of arms 25 with a column-totalizer carriage 26, which may be mounted to travel along a4 rail 27 secured to the frame of the machine, by means of balls 28 runnin in opposed V grooves in the carriage 26 an the rail 27, respectively. One or more adjustable column-totalizers 29 are positioned on the totalizer carriage 26 by means of teeth 3() on the totalizer engaging with teeth 30* on the totalizer carriage, and the totalizers are held in place by means of dogs 31 on the totalizers engaging in grooves 32 in the to talizer carriage. Each totalizer 29 is provided with the usual dialwheels 33 andcomputing Wheels 33, which, in passing through a computing zone1 are brought into successive engagement with, and are actuated by, a master wheel 34. The master wheel 34 may be actuated by means such as those more fully described in said eopending application No. 186,098.

Provision may also be made of a cross-totalizer 35 of the same general construction as the column-totalizers 29, and provided with dial wheels 36 and with computing wheels 37, which are brought successively into engagement with, and are actuated by a master wheel 38, which may be actuated by the numeral keys by means more fully described in said co-pending application No. 186,098. Said cross-totalizer 35 is also adjustably positioned on cross-totalizer carrage 39 by means of teeth 40 on the crosstotalizer engaging with teeth 41 on the crosstotalizer carriage, and maintained in such position by means of dog 42 extending into a groove 43, the cross-totalizer carriage being mounted for movement, along a rail 44, by means of balls 45 engaging in opposed V-shaped grooves in the cross-totalizer carria e 39 and rail 44, respectively.

n order to rapidly position the carriage in computing zones, provision may be made of a rack 46 on whichstops 47 may be adjustably positioned to be engaged by tabulator plungers 48. Such tabulator stops 47 may be utilized in picking up the cross-td talizer t0 carry it through a computing zone with the typewriter carriage. In performing this operation, each stop 47 engages a pickup hook 49 on a pick-up bar 50 pivoted at 51 on a slide bar 52, and carries both the bar 50 and slide bar 52 with the carriage through a computing zone. The bar 50 1s ieldingly supported by means of a lever 53 having a fol ower 54 to be engaged by an edge portion 55 of the bar, duringmovement of the latter with the carriage, saidlever 53 being pivoted at 56 and urged by spring 57- to press the follower 54`against the edge portion 55 of the bar 50. A stop 58 is provided to limit'the upper movement of the follower 54, and the pick-up bar 50 is rovided with depressions 59 and 60 to a low the pick-up bar to be depressed when in its normal position and at the time when it is lcarried out of the computing zone.

The control of the pick-up bar 50 is also effected by means of `a pin 61 on said bar engaging in a slot 62 on a plate 63, secured to a fixed part of the frame. A cam 64 at one end of the slot is engaged by a pin 61 when the pick-up bar 50 is in its normal position and insures depression of said bar 50 in such normal position. The pick-up hook is provided with a slot '65 of suitable width to receive a stop 47, and has cams 66 and 67 at the right and left, respectively, of said slot, looking at the machine from the front, the left-hand cam 67 extending upwardly beyond the right-hand cam 66.

The operation of a stop 47 on the pick-up hook 49 is vas follows. As the stop 47 enters a computing zone, it passes over the cam 66 and engages the upper part of the cam 67 and carries the hook 49 to the left. The pin 61 then passes out of engagement with the cam 64, and the follower 54 is brought into engagement with the lower edge portion 55 of the pick-up bar 50, thereby causing the pick-up hook 49 to be lifted, so that the sto 47 will extend into the slot 65. This re ation between the parts is maintained until the pin 61 is brought into engagement with a cam 68, and the depression 60 is brought into position abovev the follower 54. The pick-up bar 50 will then be depressed and the pick-up hook 49 de pressed, so as to break the connection between the same and the stop 47.

The advance movement of the hook 49 .is transmitted from the slide 52 by means of a rack 69 thereon to a toothed segment 70 on a stub shaft 71, the motion of the toothed segment 70 being'transmitted in turn by a second toothed segment 70* to a pinion 72 at the rear end of the forwardly extending shaft 73. A pinion 74 at the forward end of the shaft meshes with a rack 75 on the cross-totalizer carriage 39, and these parts serve to transmit the movement of the shaft 73 to the crosstotalizer carriage.

Upon release of the pick-up hook 49 from the stop 47, the cross-totalizer carriage amd the connections between 4the same and the pick-up hook 49 may be restored to their normal positions by any suitable means, such as those disclosed in said prior application No. 186,098. The structure so far described is in general the same as that described in said a plication No. 186,098.

The dial whee s 33 in each column-totalizer are arranged so as to provide suitable punctuation spaces, and in order to prevent the typewriting of figures in punctuation spaces, provision is made of a plurality of cams 76 on the column-totalizer. In passing through a computing zone, said cams 76 are brought into engagement at the proper times with a trip member 77 pivoted at 77 on a lever 78 mounted on a fixed pivot 79, a sprin 80 connected to said trip member 77 yiel ingly holding the same against-a pin 81, so that4 the tri 77'will be held against movement relatively to leverv78 when the totalizer is passing through a Qomputin zone in the normal operation of the machine but will be permitted to yield when the totalizer is returned to the ri ht of the' machine. The lever 78 and trip 7 may be considered as a feeler to coperate with a column-totalizer. The movement- Of the lever 78 is transmitted by pivot pin 82 to a link 83 pivoted to the upper end of lever 84 pivoted at 85 on a fixed part of the frame. A link 86 pivoted at 87 to the lower end 0f lever 84 connects said lever to an arm 88 rotatably supported on a post 89, and urged forwardly by means of a spring 90 connected at one end to a pin 91 on said post 89 and at the other end with said arm 88. It will be seen that the action of the spring tends to hold the tri 77 in position to be engaged by the cams 6.

Fixed with reference to arm 88 is an arm 92 provided with a Stop 93 normally in the path of the loose dog 22 to limit the movement of the latter when released from the escapement wheel, thereby determining a letter-space feeding movement of the carriage. When, however, the trip 77 is actuated by cam 76, the stop 93 is moved forwardly so that a notch 94 in said arm 92 is brought opposite the loose dog 22, thus permitting movement of the latter until it is brought into contact with a fixed stop 95, and determining a double letter-space movement of the carriage. The unctuationskipping mechanism thus described in general may be the same as that disclosed in said ap lication No. 176,676.

Usually the cross-totalizer Ais carried through a computing zone in connection with the travel of the column-totalizer through the said zone. Under such conditions, it is evident that the control of the punctuation-skipping means for the columntotalizer will produce the same result for the cross-totalizer. In case the crosstotal izer, however, is carried through a. computing zone with a column-totalizer, the punctuation-skipping means just described will be ineffective.

In order to obtain automatic punctuation-skippingA for a cross-totalizer, in case it is carried through a computing zone indeendently of a column-totalizer, provision 1s made of a series of cams 96, which, in passing through a computing zone, engage a trip 97 pivoted at 98 on afeeler arin 99, and yieldingly held by a spring 100 against a lpin 101 on said arm 99, so that when engaged by the cams 96, the trip 97 will be held against movement on the arm 99, and, on the return movement of the cross-totalizer, the tri 97 may yield and prevent actuation of t e arm 99 by the cams, 96. The feelerarm 99 is fixed on the lower end' of a shaft 102 mounted in brackets 103 on the frame of the machine, and another arm 104 fixed on the shaft 102 at its upper end engages pin 82 by means of a fork 105 at -the forward end of said arm 104 embracing said pin 82. 4

It will be evident that with the present structure the punctuation-skipping mechanism will be rendered effective automatically by either a column-totalizer or a cross-totalizer, or when both are carried through a computing zone together.

Variations may be resorted to within the scope of the invention, and ortions of the im i'ovements ma be used without others.
