Application filed July 9,1906. Serial No, 326,335-

To all whom i t may concern Be it known that I, HENRY .T. One, a

Gibson and "State of Indians, have invented certain new and useful Improvements, in Operating Mechan ism for'Type-Writing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in type- 'writ ers, linotypemachines and the like, and more stance," as operating the type levers of a typewriting machine or the like, returning the paper or platen carriage of a typewriter from one end of the machine to the other, and shifting the cylindrical paper roller or platen on the typewriter carriage after each line has been written, said mechanism being controlled by a key or-keys upon the keyboard of the machine. With the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts hereinalter described and claimed. l

In the accompanying drawings, Figure 1. is a sectional view" through the mechanism embodying my invention; Fig. 2 is a similar view through a slightly modified form of the invention; Fig. 3 is a vertical sectional view through a typewriter, showing the improved operating mechanism applied thereto for operating tlie type levers of the machine; and Fig, 4 is a horizontal sectional view.

The improved operating mechanism comprises a stationary cylinder or tube 1 and a sl-idable cylinder or tube 2 which is adapted to telescope the cylinder or tube land to be actuated thereon either by pressure or suction within the said cylinders or tubes, the pressure or suction being controlled by a valve device 3 comprising a casing 4 which is connected to a pipe or tube 5 and which contains oppositely disposed conical valve seats 6, 7 adapted to be alternately engaged by i citizen of the- United States, residing at Princeton, in the county of lever or other movable element 12 which is adapted to actuate.

When compressed air or other fluid under pressure is employed for operating the sliding cylinder 2, the pipe 5 is used as a supplypipe and thevalve 8 may be forced upon its seatby the pressure within said pipe or by a suitable actuatingspring, so that ,communication betweenthe pipe 5 and the cylinder 1 is normally cut off and communication between the latter and the atmosphere is:'established, owing to the open position .of the valve 9. When the key lover or element 11 is depressed, the valve stem, 10 will be moved inwardly to cause the valve 9 to close upon its, seat and thevalv 8 to be raised from its seat, so that the compressed air in the pipe 5 will enter'the telescoping cylinders 1, Z-and move the lat The return movement of the cylinder 2 may be effected-- I by gravity or by means of a suitable spring 13. When it is desired to operate the cylinder 2 by suction instead oi pressure, it will be understood that the normal position of the valve device'3 willbe reversed, so that the normalposition of. the valve 8 will be open, and of-the valve 9 closed. v, r In the form of the'mechanism shown in Fig. 1, the

' lever orelement 12 is actuated in but one direction,

but where it is desired to actuate said element in both directions, I preferablyemploy the construction shown in Figi 2'in which the.op erating mechanism isduplicated. It will be seen that in this construction, two of the valve casings 4 are secured at diametrically opposite points, in the supply pipe 5, and the iiwo valve stems are connected together as shown at 14, one end of said double valve stem being engaged by a spring15 which actuates it in one direction, and its opposite-end by the lever or element'll which actuatcs it in the gpposite direction". The two sliding cylinders or tubes 2- 2 are connected to the lever or element 12, which is here shown in the form of a bell-crank, It will 'be noted that when the lever 11 is operated, the compressed air within the pipe 5 will enter through one of the valves 'ter outwardly to actuate the lever or element 12.

into the cylinders upon one side and actuate the lever This improved operatmg mechanism may beadapted v for various uses upon typewriteralinotype machines and the'like, and in Figs; 3 and 4' of the drawings it'is shown applied to a typewriter of well known form, for

operating the type bar levers oi the same. T; One of the operating devices or mechanismsis interposed between T each of the type bar levers and its key lever on the key- I 1 board, and they are arranged preferably in one or more transverse rows inthelower central portion of the name .1 10

17, as shown in Fig. 4. The usual typebar keylevers 18 of the machine are connected, by1inks or other suitable connections 19, to key levers 20, which in the ordinary typewriters are the key levers, but which' are here shown as having their forward ends bent downwardly and apertured to receive guide pins 21 carried by the sliding cylinders 2 of the operating mechanisms. Coil springs 22 surround the stems 21 between the levers 20 and a suitable support 23, and serve to return the levers and the cylinders 2 to their normal positions. The cylinders 1, 2 are disposed vertically, and the torinerare directly connected to the valve casings 4 of the valve devices 3 which are secured to transversely extending supply pipes ,5, Each of the latter has oneof its ends closed and its other end connected to a pipe 23 leading from a suitable source of supply and controlled by a cut-off and regulating-valve 24. The stems 10 of the valve devices 3 project forwardly through and slide in a suitable guide 25, and are loosely connected to key levers 26 which form the keyboard of the typewriter. These levers are pivoted at 27 and are elevated by coil springs 28 which surround guide stems 29 depending from them and sliding in openings in a guide 30.

It will be seen-that when any one of the key levers 26 is depressed, it will actuate the valves of one of the devices 3 and thereby admit compressed air into one of the pairs of cylinders 1, 2 to cause the latter to actuate one of the levers 20, which in turn actuates the type bar lever 18 to which it is connected. It will be seen that this mechanism will cause the type bar lever 18 to be quickly actuated and the stroke orlmovement of the lever 26 need be but very slight. 1

While I have shown and described but one-way in which my improved operating mechanism may be em-' ployed, it"will be understood that I do not wish to be limited to this use nor to the manner in which it is effected. I

It will be understood that various changes in the form, proportion and arrangement of parts may be made within the scope of the appended claims.

In a mechanism of the character described. the c0mbination with an actuating and an actuated element, oi a stationary cylinder. a sliding cylinder tQlQSCOplCilll) engaged with said stationary cylinder for operating said actuated element, a supply pipe, a connection between said supply pipe and said stationary cylinder having corn-' munlcation with said parts and with the atmosphere, and
