l PEN OR PNCIL POINT PROTECTOR.

Specification of Letters Patent.

' Patented Aug. 11, 1908.*

Application led- January 14, 1908. Serial No. 410,803.

To all .whom it ymay concern:

Be it known that I, HERBERT )L S'rUiiGis, citizen of the United States, residing at Kansas City, in the county of Jackson and State r of Missouri, have invented certain new and useful Improvements in Pen or Pencil Point Protectors, of which the following is a speciication.

This invention relates to pen or pencil point protectors and more especially to protectors of that type comprising a section or member fitted upon the pencil with the point of the latter protruding throughit and a companion section or nieniber tting telescopic-ally upon the Iirstnained section and adapted when occupying one osition thereon to expose the point of tic pencil and when occupying its other position to cover and protect such point, my object being to produce a pencil point protector of the character oiithned which can be easily and quickly secured reliably upon a )en or pencil and is ot simple, strong, diirablle and cheap construction.

To this end the invention consists in cer- `tain novel and peculiar features of construction and organization as hereinafter described aiid claimed g and in order that it ma v be fully understood reference is to be had to the accompanying dra-wing, in which- Figure 1, is a side view of a pencil equipped with a oiiit protector embodying my invention. iig. 2, is a view of the same taken at right angles to the view shown in Fig. 1. Fig. 3, is al view similar to Fig. l but with the parts iii the position to which theyare adjusted to expose the point of the pencil.,

F 4, is a section on the line lY-IY of Fig. 3. Fig. 5, is a section on the line V-V of Fig. 4. Fig. 6, is a view similar to Fig. 2, with the ring pushed back to thc flange and the protector at its forward position.

In the said drawing, 1 indicates a spring metal sleeve having a truncated front end 2,

sleeve 1 rigidly upon the latter, as shown inl and an outwardly projecting bead 3 at its rear end'. diametrically opposite points at -1 so that sncli end at opposite sic It is also slitted at its rear end at its front end with a contracted or truncated end S. At opposite sides and in longitudiL nal ahnenieut with slits 4, sleeve 7 1s pro` vided with longitudinal slots 9, the rear ends of the slots being connected by a transverse slit 10 so as to forni between the saine and the slots a stift` spring 1l, the sleeve rear; ward of said spi-ing constituting a solid ring 12 which fits snugly upon sleeve 1. The' spring 11 `is indented centrally at its rear edge to provide an inwardly rejecting pin or lug 13 engaginflr thc guide s ot 6.

14 indicates a clamp ring fitting snugly on sleeve 1 at the rear end of sleeve 7. Initially, that is before the pencil 15, is equipped with the retcctor, the ring 14 is disposed forward ol) the spring jaws and the sleeve 7 is fitted upon sleeve 1 with its pin 13 in engagement with the front end of guide slot 6. With the parts in this relation the protector is slipped upon the sharpened pencil until the contracted or truncated oition 2 passes the point of the pencil andp is arrested by conim'g in contact with the beveled or shai eiied portion of the wood, the teeth of t ie spring jaws pressing lightly against opposite sides of the pencil. the clamp ring rearward y, accomplishing this purpose preferably by grasping sleeve 7 and sliding it rearward until the ring comes into engagement with the bead 3 at the rear end of sleeve 1, this rearward adjustment of the ring compressing the jaws of sleeve 1 and effecting the einbedinent of their teeth 5 into the wood of the pencil so as to clamp said F ig. 4. The saine adjustment results in the exposure of the point of the pencil. When the pencil is to be laid aside or placed in oiies pocket the sleeve 7 is slid forward from 9 the position shown in Figs. 3 and 4 to the position shown in Figs. 1 and 2 so as to prorect t-lie ioint of the pencil from breakage, the ring lliowever, remaining in the position shown in Figs. 3 and 4.

When the pencil is to be resharpencd the i sleeve 7 and ring 14 are slid forward to peres of said slits shall f forni a pair of spring jaws each provided near its rear extremity and about centrally be-l tween the slits with an indented portion Aor L tooth 5, and one of them with a longitudinal 5 as described, it being obvious that when it is slot 6 forward of its tooth.

indicates a companion sleeve of spi'ing metal fitted on sleeve 1 and also provided at i teeth 5 are embedded 1n the wood o the pen- 110 init the jaws of sleeve 1 to spring apart slightly and enable the operator to remove the entire protector from the pencil preliiiiinary to the resharpening of the saine. The protector is then resecuied upon the pencil reseeiired'aftcr the sharpening operation, the

The operator then slides of einbe'dnient.

By the formation of t-he spring 11 forward i 'of the rear end of sleeve 7 and the consequent production of the solid rin lr 12 rearward ot said spring, said sleeve is icld solidly and I reliably upon sleeve 1 and cannot be rocked 'or oscillated sufficiently to eflect the disengagement of the pin 13 from the guide slot and the consequent dislodgment of sleeve 7 from sleeve 1, as would be possible if the slots 9 extending to the rear edge of sleeve 7 ,'it being necessary yto effect. such dislodginent to applya positive outward ressure on the rear end of spring 11. Wien the sleeve 7 is fitted upon sleeve 1 however, the contracted or truncated end 2 of the latter is engaged by pin 13 and as a result of such engagement spring 11 yields outward until said in registers with and snaps into slotJ 6 as will be readily understood.

- From the above description it will be apparent that I have produced a pen or pencil point protector possessing the features of advantage enumerated and I wish it t0 be vunderstood that I do not desire to be restricted to the exact details of construction shown and described as various modifications will occur to one skilled in the art.

Having thus described the invention what I claim as new and desire to secure by Letters Patent, is

1. A pen or pencil point protector coinprising a sleeve having a spring jaw at its rear end and a. truncated front end, and provided with a longitudinal slot, a clamp ring fitting on the sleeve and adapted to be slid rearwardly thereon to press the spring jaw inwardly, and a second sleeve fitting telescopieally on the first forward of the ring and rovided between its ends with a spring havlng an inwardly project-ing pin for engage- `on the sleeve and adapted to ment with the longitudinal slot of the first-- named sleeve and adapted when slid rearwardly to force the rinighin the saine direction in the event that said rnfhs'not been-pre viously so adjusted.

2. A pen lor pencil point protector, comprising a sleeve having a spring jaw atits rea-r end and a truncated front end, and provided with a longitudinal slot, a clam i ringl fitting lie slid'rearwardly thereon to press the spring jawinwardly, and a second sleeve to fit snugly on the first and provided with a pair of longitudinal slots terminating short of its front and rear ends and with a transverse slit connecting the rear ends of the longitudinal slots to form between said slots and said slit a spring, and provided with a pin projecting inwardly from said spring into engagement with the longitudinal slot of the first-named sleeve.

3. A pen or pencil point protector, comprising a sleeve having longitudinal slits extending through its rear end to form a pair of -spring jaws atsuclr end and also having a longitudinal slot between said slits, and teeth projecting inwardly from the jaws rearward of said slot, a clamp ring fitting snugly on said sleeve, and a second sleeve fitting slidingly on the first and capable when forced rearwardly of sliding said ring in the .same direction to cause it to compress said jaws; said second sleeve having a spring between its ends provided with an inwardly projecting pin engaging the slot of the firstnamed sleeve.

In testimony whereof I aflix my signature,- in the presence of two witnesses.
