Specification of Letters latent.

Patented July 2o, 190e.

Application filed December 22,1908. Serial No. 468,742.

`To eli whom 'it may concern: 4

Be it known that I, Louis HENRY LLOYD,

a citizen of the United States of Arnerica,'

dull and clear specification, reference being had to the accompanying drawings, in which- 1 Figure 1 is a pers ective view of the pen as it appears in use lig'. 2 is a' sideelevation with the guard-tube in cross-section, theA guard-tube being adjusted to stop the feed and protect thepen; Fig. 3 is a similar view to Fig. 2 on a section through the guard-tube taken at a different angle; and Fig. 4 is a transverse section on the line 4:--41 of Fig. 2.

The object of this invention is to rovide simple means for entirely stop ing t e feed when the penis not in use an also to provide an improved guard-sleeve for roteeting the pen while not in use, as more fu ly hereinafter setl forth.

Referring to the drztwings by reference characters a, designates an open-ended tube adapted to freely slide on the pen-body and provided with a pin b at its upper end which works in a longitudinal guide groove c formed in the pen-barrel. At eachend this groove is extended laterally to form a re'verse curve c whereby the guard-tube may be locked at either end of the pen-barre When the uard tube is locked at the upfper end of the iarrel it is out of the way an when locked at the lower end of the barrel it projects far enough beyond the point of the pen to protect the same.

A small metal collar or band d is fastened to the pen-barrel at or near its lower end and made lntegral with this band is a pair of i spring clamping i'ingers e, e,` which extend forwardlyone over the toV of the pen and the other underneath the eed-tube. These spring arms normally tend. to spring away from the pen and the feeder, I'es'ectively, but they are so curved that when t e guardtube is slid forwardly into position the inner Wall of' the tube iinpinges against both arms and forces them toward each other, causing thein to clam the pen and the feeder/tightly but resilicntlp together and thus prevent leakage lof in r' while the pen is /out of use. The finger e which bears against the back of the pen is referably bifurcated, as shown, to embrace t e nibs of the pen and hold them closely together while they are pressed against the feeder.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. A fountain pen provided with a pair of spring clamping fingers extending forwardly from its ,forward enc and means on the penbody for clamping said fingers, respectively, against the baelr of the pen-point and the under side of the feeder.

2. A. fountain en provided with a pair of spring clamping ingers extending forwardly from its forward end, 'and moans-on. the penbody for clamping said fingers, respectively, against vthe b'aek of the pen-point and the under side of the feeder, said means eonsisting of a guard-tube slidably mounted on the peinbody. Y

In testimony whereof I hereunto aiiix my signature in the presence of two witnesses this 12th day of Dee; 1908.
