TYPEwnrrING MACHINE.

Application filed March 30, 1925.v l.Serial No. 19,204.

VMy invention relates to typewriting or Vlike machines and more particularly to clutch mechanism by which the line spacing wheel and platen maybe connected to turn together or thev platen may be turned independently of the line spacing wheel for irregular spacing.

The main object of my invention, generally stated, is to provide a comparatively simple and highly efiicient positively acting.

clutch mechanism of the character specified.

A further object of the invention is to provide a clutch mechanism of the character specified which even though it is located to the left ofthe platen may nevertheless be released by one hand without disturbing the carriage from the position it has assumed in its line of travel.

To theabove and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set vforth in the following description and particularly pointed out in the appended claims. in kthe accompanying drawings, wherein lile reference characters designate corresponding parts in the different views, y

1Eigure 1 is an enlarged detail vertical sec-l tional view of the clutch mechanism and some of the associated parts as they appear when the clutch is closed; the section being taken on the line 1-1 of Fig. 2 and looking in the direction of the arrows at said'line.

Figure 2 is a vertical transverse sectional view of the same taken on the line 2 2 of Fig. 1 and looking in the direction of the arrows at said line.

'Figure 3 is a view corresponding in part to Fig. 1 except that the parts-are shown disposed as they appear when the clutch is released. j Y

Figure et is a view showing, inperspective and detached, various parts of the clutch mechanism.

l have shown my invention in the present instance embodied in a Remington-Noiseless machine. It should be understood, however, thatV the clutch mechanism of my invention is of general application and may be embodied in various makes of typewriting or like machines.

The present invention is in the nature of an `.improvement on the construction disclosed in the patent to H. N. Josleyn, No. 945.956, dated-Jan. 11, 1910. I

By the present invention I am enabled to providerclutch mechanism which is in the nature of a separate unit mounted wholly outside of the platen so that the interior of the latter is unobstructed and if desired may receive other devices, such, for example, as they damper contained within the' hollow metallic platen of the Remington-Noiseless machine. Moreover, aside from the fact that ay highly eliicient positively acting clutch mechanism is provided, I am enabled by my present invention to release the clutch with one hand without displacing the carriage to the right, even though the finger wheel for controlling the clutch is located to the left of the platen, as will hereinafter .more clearly appear."

In the drawings, 1 indicates a cylindrical platen which, in thelpresent instance, is made Vof metal and hasa hollow hub 2 formed integral therewith at its left-hand end. This hub receives a bearing in a bearing-opening in the left-hand end plateiof the carriage 4L. A disk-like supporting member 5 is provided with a centrally located cylindrical hub or extension 6 that projects from the right-handside thereof and is received in the hub 2 ofthe platengthe extension and hub being detachably fastened together by a pin .7. In thisv manner, the ysupporting mem,- ber 5 is mounted out-side of the left-hand end plate 3 of the carriage, a spacing washer 8 being interposed between said memberand the end plate. As best shown in Fig. et, the support 5 is formed with three'radially vdisposed ways 9 in which pawls or clutch members 10 have va sliding 'fit tov move radially ltowards and from the axis of the platen. Each pawl is provided withv oppositely disposed beveled engaging faces 11 and with a cut-out portion, indicated at 12. When -he parts are assembled an endless contractile spring 13 is received in the vcut-outs 12 in the pawls and exertsits force to withdraw the pawls to vclutch releasing position. A ring-lille line spacing wheel 14 is provided at lli() its inner side with an untoothed bearing pornism and there is no danger of displacing the carriage in operating the clutch. It isY justed the desired extent independently of the line spacing Wheel, the .operator releases the finger Wheel 38 and the springs 28 automatically close the clutch and positively connectI the line spacing Wheel and platen to turn together.

lf desired lany suitable means may be employed to loelrthe finger Wheel 38 and spindle 24 in releasing position shown in 3.

One highly effective means for this purpose,

and one which does not detract from the one hand operation of the clutch and lock, is disclosed in `the application of Edwin E. Barney, Sr. No. 743,199, filed Oct. 13, 1924.

From the foregoing it Will-be seen that I have provided a comparatively simple, compact 4and highly efficient platen clutch mounted entirely outside of the platen and platen frame or carriage,rleaving 'the interior of the platen unobstructed and free for use of other means if desired.V The construction is such, moreover, that Jthe line spacing Wheel, the platen clutch, and its controlling means may be readily introduced into orV removed irom the machine as a separate unit Without disconnecting or altering the relative arrangement of the parts thereof. Y

Various changes may be made in the construction vvithout departing from my invention as it is defined in the accompanying claims. f

.Vhat I claim as new and desire to secure by Letters Patent is l. In a typeivriting or like machine, the combination of a carriage; a platen carried thereby; a line spacing Wheel; and a hand controlled platen clutch mechanism eective to cause the line spacing Wheel and platen to turn together or to permitthe platen to be turned independently of said Wheel, said platen clutch mechanism comprising clutch teeth4 @carried bythe lin'e spacing Wheel, paWls that move into and out of engagement with said teeth, springpressed plungers co-acting With said pavvls to cam them into engagement With said teeth, a-finger piece to the left of the platen, andmeans controlled thereby for displacing said plurger's againstV the power of their springs by a movement f the finger 'piece to the left in the direction ofthe feed of the carriage.
