Y., A CORPORATION OF NEW JERSEY.

TYPE-WRITING MACHINE.

Application filed Kay 7, 1909.

To all whom it may concern:

Be it known that 1, JOHN C. lVlGlJAI'GHLIN, I a citizen of the United States, residing in erscy City, in the county of Hudson and 1 tate of New Jersey, have invented cert-sin new and useful Improvements in 'lype-ll iiting Machines, of which the following is a specification.

This invention relates to paper guiding or controlling devices of typewriting machines, l and psrticulady to devices of this kind which are adjustable along the platen.

The present invention is in the nature of an improvement on the devices shown in Patent No. 890,372 to R. J. Orr, dated June 9, 1908.

One of the objects of the present invention is to provide improved means for connecting the gage for the side edge of the paper at the introductory side of the platen with the paper-guiding finger which extends around the front of the platen, whereby both may be adjusted together along the platen, while the paper-guiding finger may be turned up when desired.

Upon a rod, which is fixed in the platen frame and extends along the platen, is mounted a carrier; and to this carrier is attached the gage forthe side edge of the paper; a hinged pintle being mounted in the carrier, and a front paper-guiding linger being fixed upon said pintle. The rod is longitudinally rooved, and the carrier is provided with a 'eather or spline, which is normally pressed by a spring in said groove, which releasably locks or binds the carrier against accidental displacement along the rod. The finger-piece is provided with means for relieving pressure of the spring, so as to release the carrier for free adjustment. J

, In the accompanying drawings,- Figure 1 is a perspective view of the platen frame of 5H] Underwood ty'pewriting machine, showing theinvention applied thereto. Fig. 2 is a sectional end view of the platen and other parts. Figs. 3 and 4 are sectional front views of the carrier, showing it in its looked a nd un locked positions respectively. Figs. 5 and 6 are pers )ec-tive views of the feather and cam.

The platen 1 is journaled in a platen frame 2 having an inclined paper shelf 3. 'lo the ends of the platen frame is fixed rod 4: ex.- tendin along the platenand having a longitudinav groove 5. Slidahly mounted on the bar 4 is a yoke 6, which csrries the side gage, i the front paper guiding linger, and the lockl Specification of Letters Patent.

- ing and unlocking mechanism, the bar passing through openings 7 formed in the sides 8 of the carrier.

Extending back from one of the sides 8 is an arm 9, to which is attached a side gage 10 for the side edge of the sheet of paper as it is being introduced into the machine to pass forwardly around the under side of the i the plunger, which protrudes up through the top of the carrier 6, and presses the spline down into the groove 5, causing it to bind or look the carrier 6 to the rod 4.

The top 18 of the spline is slotted at 20,

Fig. 4, to receive a reduced portion 22 of a cam pintle 21, as shown at Fig. 5. The pintle 21 is free to revolve, but prevented from transverse movement by the shoulders 23 of the cam pintle.

The cam pintle 21 is confined between a fluted portion 21 of the spring 15 and the top of the carrier 6, and may be turned to lift the spring to release the carrier. Said pintle is of circular section and provided with a. flat portion 24, which normally restsupon the top ol the carrier when the latter is locked.

A handle '25 is provided on the end of the cam pintlc 21, to turn and raise it to the position shown at Fig: 4. This relieves the pressure on the spline 1 1, and allows the car rier 6 to slide 'l'recly along the rod 4.

On turning the handle 25 down to the position shown at Fig. 3, the pintle 21 is again let down, until the flat or dwell portion 24 rests on the top of the carrier 6, allowing the spring to press on the pintle to cause it to lock the carrier.

A front guiding linger .26, carrying a roller 27, which. guides the paper on the platen is attached to an arm 28, which is connected to a pintlc 29, ournaled in the sides 8 of the carrier 6. This guiding finger is releasably held against the platen 1 by means of a spring- The lower edge abl mounted on said rod a front aier- 'on. said rod, a gage for the side edge of the pressed roll 30 fitting in a groove 31 formed in the pintle 29. The front guiding finger is thus hinged or swiveled on a separate bearing from the rod 4, to be capable of turning movement independently of the side gage 10.

An inclined plate or apron 32 may be se cured to the front of the carrier by screws 33, to guide the paper up as it leaves the platen 1.
