'COMBINED TYP-XVRTTING AND :COMEUTIG HAGHINE.-

maaier.

T0 all/whom it 77mg concern Be 1t known that I, GUs'rAvn 0. Dnonnnn,

a citizen of the United States, residing in New York city, in the county of New York and .State of New York, have invented certain new and useul'mprovements in Coinbined 'Type- Writing and Computing Machines, of which thefollowing is a specification.

This invention relates to the type of com# hined typewriting and `computing'machines in Awhich a computing Vcarriage is intermit tently connected to the carriage of a typewriter, to travel therewith. A hook is connected tothe computing carriage, and is adapted. to engage any of a series of lugs placed upon the typewriter carriage, which is power-driven. Mechanism is provided r'or automatically disconnecting said hook from. the lugs in succession at certain oints in the travel of the typewriter and computing carriages. A machine of this type is illustrated in the pending-application of f'alter.`Wright, No. 574,813, tiled August l, 1910. The present invention relates to the hook used in this class of machines.

One object of the invention is to improve the means for automatically disconnecting the hook, so that such disconnection may be effected Without' consumingan undue portion of the carriage driving power. To this end I provide a lever -carrying a roll or rollercam, which is engaged bythe lug, which is on the typewriter carriage. The provision of the roller cam renders the releasing action very light or easy. This releasing lever extends to the hook and bears upon a roll which is carried on said hook. Hence at the hook-releasing operation, the entire function is performed through rollercontacts, so that 'friction and binding are-reduced or eliminated, and the lhook is promptly released, and the paper carriage is not retarded in its travel. Provision is also made for having the roller cam on the releasing lever normally out of' the path of the carriage lugs.

Another feature of the invention consists of means for locking the hook out o1' use,

so as topermit the'use of the carriage in# dependently of the ,computing mechanism when desired.v For'this purpose, a button is provided which has a cam to engage a partofthe hook land hold the same de- Specication oz" Letters Patent.

3 is a plan of the devices seen at F ig. ll.

Fig. i illustrates the .manner of locking the hoolnout of use. Fig. 5 is a perspective view of the hook and its connection to the computing carriage; Fig. 6 is a pers iec tive view of a hook-releasing lever. Fig. 7 shows one position o1 the parts in movin" fromhe Fiml ositioi t th Fi .2 't' n g p nto Le g posi 1o--. A master wheel, in the form of teeth or pins 1, projecting from a.hub 2, is carried upon an arbor 3, which extends from an end plate 4 o'a computing carriage. The master wheel engages internal gears 5 upon computing wheels G, of which one is shown; said computing wheels engaging gears 7 provided'upon dial wheelsS.

The computing carriage has a pin 9 engaging a slot l() on thevforward end of a lever ll of the first order, which isfulcrumed at l2 upon the framework of they machine, and at its rear end has a slot 13 to engage apin l-- Iprojecting down from a block 15, in which is ixed one end of a stem 16 of a hook 17. This hook is lifted by a spring 18 (pressing up. againstsaid stem) into engagement with any of a series of lugs 1.9, adjustable along a rack 20, which is connected to or orms part ofthe paper carriage of the typewriting machine; said paper carriage driven in the direction shown i l, which is a rear view.4 As the carriage fee or" the lug 19 encounters a roll or roller cam 2l which is pivoted atEZQ upony a lever 23, the latter fulcrumed at 24 upont'he frames along, the bottom edge f work and having a stop .arm 25 to engage a stop 2G also on the framework. The lug pushes thelever 23 down from they position at 1Mig. 7 to the position at Fig-2, and dur-V ing such movement .the 'end of saidA lever hearsdown upon a roll roller cam 27, pivl oted at 28 on ,the hook 17, and carries the .obviating the screeching and jar that come with the use of steep cani faces in restricted spaces. Moreover, cams having these i'aces are apt to jam after a period oit non-use. They become less slippery, either by ac'ci'uniilation of dirt from the surrounding air, by incipient rust, or from some other cause.. These objections and draw-backs 1 avoid in my construction.

It will be understood that the roll or roller cam 2l normally occupies the position at. Fig. l entirely below the lugs 1S), so-that the paper carriage can be run along; in both direct-ions without the lugs colliding with said roll oi' roller cam 2l. wfiVhile'the hook l? is moving` from the position at Fie: l to the position at Fig. 7, the roll o roller cam 2T on said hook engages n cain edge 2l) on the rear end of the lever 23 and raises the saine, as seen at Fig. 7. rihis movement is rendered very easy by the use ot the roll or roller 'ani 2, so that the movement ot' the carriage is not retarded. 'By this means, the lever Z3 is lifted sufficiently' to bring the roll or roller cam 21 into the path of thc :ulvancing` lug 19, and the latter strikes the roll and de presses the lever '23, to release the hook 17, as seen at Fig. ,'Eherenpon, a spring 30, connected to lever l1, returns the hook 17,- lever 1l, and con'iputingl carriage -l to starting positions; or at least the spring` 1S lifts said hook into engagement with the next lug' 19 on the rack 20; While the lever gravitates to its normal position at Fig. i.

lVhen it is desired to silence the ho'ok 17, the button 31, Fig. 5, is turned, sai'd button being fixed upon the projecting end of a short shaft and acam 33 projecting from said shaft above the stein 16 of the hook and .moved by said button from the idle position at Fig.- l to eliective position at Fig. t. frictionl spring 3st forks the shaft and presses against the hub of the button 3l,- s0 as to hold thelatter frictionally with the cam or pin 33 both in the effective position at Fig'. 'at and in the idle position at Fig. l..

Variations may be resorted to within the scope of the inventionoand portions ot' the iininovements may be used without others.
