' Claims. (c aw-1i) 4 V, l I I suitable "mam for mama; and sutiabiy .My invention relatesgenerally to pencil holders, and particularly to an adjustable pencil holder wherein a novel arrangement and combination of parts is utilized to produce a struc- 5 ture which may act as-a guard for the pointed end and for the eraser equipped end of the pencil used therewith, when these are not in use. 1

It is also an important object'of my invention to provide a light-weight, neat, convenient and relatively inexpensive pencil, holder of the. type described, which is adjustable so that when the pencil is not in use for writinghor erasing, the

pointed end of the pencil and the. eraser equipped.

end of the pencil will be positively coveredand protected, while the pencil and holder is being carried about as in the pocket: t

Other objects and advantages of my invention will be apparent from a reading of the following description in connection 1 with the drawing, wherein for purposes of illustration I have shown a preferredembodiment of my invention.

In the drawing:--. Y Figure 1. is a general side elevational view of the embodiment showing the pointed end of a pencil extended therefromand Fig. 2. is an elevational view taken approxiately at right angles to. Fig. 1, looking from the left.

Fig. 3 is ;a horizontal sectional view through Fig.1. 7 i

Fig. 4 is a side elevational view of a slide and Fig. '5 isa horizontal sectional view through the lower end portion of the holder.

Referring in detail to the drawing, wherein like numerals refer to like parts throughout the same, the numeral 5 generally designates a tube of uniform diameter in which is closely and slidably received an ordinary lead pencil 6 having the pointed end 7. The lower end portion of the tubular holder 5 has a punched out portion 8 which is curvedly and inwardly directed as indicated in Fig. 5 so as to bear against and slightly dig into the side of the pencil for holding the same against too free sliding in theholder.

In one side and extending the full length of the holder 5 is a relatively narrow slot 8. Mounted upon the exterior of the holder and slidable thereon for the full length of the holder is a bracket member generally designated 9 which comprises the longitudinal web portion 10 from opposite edges of the central portion of which proceedears 11 having a hole 12 therein. From opposite ends of the same edges proceed laterally curved upper arms 13 and similar lower arms 14. The pairs of

arms

13, 13 and 14, 14 have a cated overthe slot 8.

the slot 8 with a guiding-function. It will be embracingthe exterior of the holder f5.so as to :be can'ied byjthe tube. The web portion 10has a slight transverse curvature as'seen in Fig.v 3 to conform to the contour ofthe exterior of the holder. Normally theweb portion 10 beilo- A U-shaped member15 through its arms, a pivot pin 16 which-is riveted as indicated at 17 on the outside of the said arms. This pin is arranged topass also through theholes12 in the ears of the slide '9.-sothat the arms, oflthe U-shaped member 15 arexoutside' of and movedly engaged withtheears 11'-as shown in Fig; 3;

The U-shaped member 15 has on its 'bight portion an inwardly projecting portion .518? on the-end of which is formed along; arm 19 which.

is herein called the pperatingarmrWhich' has the normal :vertical disposition shown inFig; 1. From another inwardly projecting portion 20 on the lower edge of thebight portion ;.of the, U-shaped member 15 there projects downwardly at an angle a tapered penciLengagingfmember 21 which has on its lower end a horizontallydirected point 22 for engagement .throughi the 'slot 8 and-into the side ofthe pencflafi. it w be observed, that the operating arm 19 :is Jflat and comparatively wide whiletthepencil engaging member21; is flatjand tapering. 1,

On the pivot pin16. between the, cars 11 isan eye, portion 23 of.-a spring member generally designated 24 :which: is generally Nrshaped in form and has a long leg 25 outwardly disposed against the inside surface of the operating member 19 and therelatively short arm 26 working in the opposite direction against the holder 5' whereby to maintain theoperating member 19 normally diverged away from the. holder 5 and the pencil engaging member 21 forced through the slot 8 so as to bite with its point 22 into the 24 has an expanded portion 27 which rests against the side of the holder and has a portion which projects through the slot 8 so as to endow .96 side of the pencil. The short arm 26 of the spring obvious that the arms 25, 26 are provided to have a normal tendency to spread away from each other and produce the pencil holding actions described.

It will be obvious that whenever the operating member 19 is pressed towardthe holder 5, the" point 22 will be released from the pencil so that the pencil may be adjusted in the holder relative to the clamping structure. It will also be obvious that when the point 221s engaged with $19 the pencil, that the pencil and the clamping structure being thus connected, and may he slid relative to the holder.

This arrangement makes it possible to sheath either end of the pencil within the holder in such a way that it will stay sheathed during carrying of the device in the pocket. Because of the slidable mounting of the slide'9, the entire clamping structure 'may.v he slid relative to the holder wheneventhepoint 22 has'been released-from the pencil, 'or when not released from the pencil,

the pencil will slide with the clamping structure.

Due'to the adjustability of the clamping structure practically the full length of the holder,

pencils of varying lengths, even very short lengths of pencils may be utilized withcomplete convenience in my'invention; Since it is the. breaking of pencil points which entails resharp" ening of the pencil, which most quickly con+ sumes a pencil, it will be obvious that the device of theinvention providing for complete=sheathing ofthe pointed end or of the eraser equipped end, providesfor preservation of these ends when the pencil and holder is not in use, thereby effecting considerable economies.

:Though I have shown and described herein a preferred, embodiment of my invention, it is to be definitely understood-that -I do not desire to limit the application of my invention thereto,

and any change or changes-may be made in material'and structure and arrangementof parts, within the-spirit of the invention and the scope of the subjoined claim's r V Having thus described my invention, what I claim'as new is:-
