TYPE-WRITING MACHINE Speificabion 01 Letters Patent.

Patented June 15, 1909.

Application filed Match 17, 1909. Serial No. 483,928.

T0 1112 whom it may concern:

Be itlmown that I, FRANK A. Y I'NG, a citizen of the United States, residing in New York, in the couhtyof New York andgSt-Me of New York, have invented certain new and useful Iniprovements in Type-VVriting Machines, of which the folloiving is a specification.

This invention relates generally to tabulatmg mechamsm for typewrrtmg and other machines, and particularly to means l'or enabling the carnage to jump to any selected column or field, such devices known in the art as column skippers.

The principal object of the invention is to produce a simple and inexpensive meohanism readily applicable to typewriting machines for efl'ect1ng such jmping of the carriage;

In carrying out my invention in one form the colunm stops are'placed atzindesired intervals along a rack provided upon the carriage, and a single stop is'mounted upon the 4 main trame et the machine to coperate with said colnmn stops as desired, for arresting the carriage. At the kevhoard of the machine is nmunted a row ot colnmn stop keys numbered to correspond With, the column stops. Said keys are connecsted t0 means for cansing said single stop upon the main trame to rise at the proper time'to engage that sto which corresponds to the actuated key. li, alter returning the oarriage to begin a new line, the operator desires to write in the first column, ha de nasses the key marked 1, and said niainirame'stopis caused to engage the first column stop in the series to arrest the carriago at thatpoint. If then the. opera' tor wants to write-in the fifth column for instance, he depresses the key markcd and said mam-frame stop is caused to use to engage the filth column stop and a'rrest the carnage at that point; and soon.

To aceomphsh the aforesa1d results each column stop is provided witli a tappet, and

upon the frame ofthe machine is mounted an interponent to be engaged and operated by the tappets, and in turn t0 thrust up the singl s!" 1 which is mounted on the main trame;

. or in uther words, the. movement of the car riage is made available to cause the mainframe stop to project into the pathof one of the column sto )s on the carriage. Said tappets are of grat uated lengths, or atleast are arranged in echelon, and said interponentis tliruSt up variably, by the difierent .;eys; the

inter mnent being operated by a stepped mem er and the keys having levers which engage the dilierent steps; the first key thrnsting the interponent up toits highes't in position, tobe engaged and operated by the short-est tappet; the second key engaging the next step on the interponent carrier, to thrust the interponent np not quite so high, in position to skip the first tappet and to he engaged by the second; and so on'for the whole series.

It will be seen that certain featureS 01 the invention may be used for otherpurposes th an colunm-Skipping.

In the accompanying drawings, Figure 1 is a perspective re'ar view of the picsent improvements a strike ty ewrltlng machine. Fig. 23 is a sectional sir e eleVation of the same; one of the cou1nn-.selecting keys being shown depressed. Fig. 3 is a pers motivefront view of the colamn-selectin devises illustrating ,the manner in which the carriage is caused to thrust up the main-frame stop to arrest the carriage. Fig. 4 is a perspective view to illustrate the rnanner of connecting a keystem to a key-lever. Fig. 5 is a perspective view of a numbered column stop (with its integral tappet) and the stop on the main fr.me. Fig. 6 illustrates the series of colunm stops infront edge view separated from the column-stop rack; this view illnstrating the echelon arrangement of the t.ppbtsoh' the column stops.

In said machine types 1 are caused by keys 2 to strike against the front side of a pl';xten

3, Which is In0nted upon a carriage 4, sliding on one or more rails 5 and connected by a strap 6 t0 a spring-barrel 7. Up0n the carriage is provided a relasable rack 8, which meshes with a inion 9 forming part of an escapement m'ec anism.

Keys 10 are arranged in a row at the back of the keyboard of the machine and are nunibered from 1 to 10,to correspond With the nnmberin of a set of column stops 1] adjustable a ong a rack 12 pr0vided upon the carriage 4; each column'stop formed of a plate oi sheet metal and eompfising forks '13, 14, and having at its rear end anextensioh turned over to form anumberbearifig ear 16. It will be understood that there are as many rolumn stops as keyS, and that the first column sto is numbered l,arid is at the left hand and oFthe rack in Fig. 3, to be the ing direction to projct the first stop in a cause the first stop to move into the path of nection between the key stem and the. lever 35, Fig. 4; the lever being perforated to receive said stud. The stem 38 and keeper 60 are'made of sheet metal, and the stem is off set at 64 below the pivot 61 of the keeper, the latter being fiat, so. that room is made. between the stem and the keeper to receive the lever 35. As thse stems 38 usually have to pass clown between closely arranged typokey levers 65, Fig. 2, this method of attachin; them is found inexpensive and convenierit, and permits ready detachmentwhon required. The key stems 38 are gu1ded in a comb 66 secured upon the framework, and at their upper ends having shoulders 67 to serve as stopsfor arresti .g the keys, the latter having uniform depres'sions. The key stems are releasably retained in the comb by a keeper bar 68 detachably connected by sCrews 69 to the comb 66.

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