Specification of Letters Patent.
Application led December 2, 1915. Serial No. 64,632.
To all whom t may concern: l
Be it known Ithat I, CHARLES C. SPENGLER, a citizen of the United States, residing at Rockford,` in the county State of Illinois, have invented certain new and useful Improvements in Pencil-Sharpeners, of which the following is a speci cation. Y
My invention relates tov pencil Sharpeners, and particularly to lthat type of pencil Sharpeners in which the sharpening operation is performed by' means of rolls provided with helically-disposed cutting edges between which rolls a pencil may be 1n- Serted. L
llt is an object of my invention to provide such a pencil Sharpener with means for guiding and centering pencils of different` siz'es in the space between the cutting rolls.
A further object of the invention is to provide the shavings receptacle with a locking key whereby it may be readily and easily Secured in position on the Sharpener or removed therefrom as desired.
A further object is to mount` the guidereducing member upon the loc-king key and carry it to and from the cutting axis by movement of the key; Valso to accomplish this without withdrawing the key from locking relation.
These and other advantages of my invention may be more readily understood by refjerence to the accompanying drawing, which shows a preferred embodiment of my invention, and in which- Figure l is a Side elevation of a pencil Sharpener embodying the invention, a part thereof being broken away and a part being shown in section;
Fig. 2 is a front elevation showing one member of the device in alternative position in dotted lines; and
Fig. 3 is a front elevation showing such member in still another position.
The pencil Sharpener in connection with which the invention is illustrated comprises a base 1, which may be suitably secured to either a horizontal or vertical surface. A support 2 is suitably Securedto the base 1, and is provided with a bearing 3, in which a revoluble cutter frame 4 is journaled. The cutter frame 4 carries the usual rolls 5 formed with helical cutting edges and arranged in the usual manner so that on rotation' of the frame by the crank 6 the rolls may be revolved around the axis of the cutter frame, and also upon their own axes. The outer end of the cutter frame is provided with an aperture 7, through which a pencil may be inserted, and by which the pencil will be centered in the Space between the cutter rolls 5. A peripheral groove 8 is formed in the outer end of the cutter frame. The support 2 is provided with a head 9 having a peripheral shoulder` l0.
shavings receptacle, erably be formed with either mica or metal sides and top 11' secured between a front plate 12 and a back plate 13 united by bars 14, 1s formed with a back opening whose edge is designed to engage the Shoulder 10 and with a flanged opening 15 in its front wall 12, which is designed to embrace the end of the cutter frame 4. The front wall 12 of the receptacle is preferably formed with oppositely disposed ears 16. A plate member 17 is Slidably and ad- ]ustably secured against the front wall 12 of the receptacle preferably by forming the plate with a Slot 18I through which' extends a screw 19 threaded into the front lwall 12. At its sides the plate 17 is formed with lingers 20, while between the fingers it is formed with the central portion 21 forming a guide-reduoing member, in which is an opening 22 smaller in size than the pencilreceiving aperture 7 inthe end of the cutter frame 4, Said guide reducing member having a convex depression that causes it to Seat slightly within the enlarged guide opening and thereby center the guide-reducingl tacle is positioned on the cutter frame, and
which may pref- Patented (Ilot. 1l, 119118..
is held there by securing the plate 17 in the position Shown in dotted lines in Fig. 2. In this position of the plate the fingers 20 engage the periheral groove 8 in the cutter frameand e ectually prevent removal of the receptacle, while at the same time the aperture 7 in the cutter frame 4 is fully exposed to allow the insertion of a pencil of the same size as the aperture. If it be desired to use the Sharpener for operating on pencils of smaller' diameter, the plate 17 is slid and adjusted to the position shownin full lines in Fig. 2, so that the opening 22 in the central portion of the plate is moved into position concentric with the aperture 7 and so that it will serve to receive and center a pencil of smaller diameter in the space between the cutter rolls 5.' The plate 17 slides behind the ears 16, which serve to guide it and hold it in position. If it be desiredto remove the receptacle from thev Sharpener, the plate 17 is slid to the position shown in Fig. 3, in which the lingers 20 are disengaged from the peripheral groove 8 in the end of the cutter frame 4, so that the receptacle may be bodilyl removed.
From the foregoing it will be seen that the key has three positions, namely, one unlocking position and two locking positions, in one of which latter positions the guidereducing-member 22 coincideswith the cutting axis and is adapted to hold the locking key in such position,while in the other the guide is removed from alinement wi-th the cutting axis and leaves the opening enlarged tol receive. a larger pencil and the receptacle 'still in locked position. y
It will be apparent to those skilled in the art that many changes could be made in the detailed construction of the partswhich I have described without departing from the 'spirit or scope of my invention as delined n the appended claims.
What I claim is:
admit a pencil in the line of the cutting axls, a receptacle removably mounted on the support, a locking key carried by the receptacle movably inter-locked with the cutter, and a guide-reducing member on said key and carried thereby into and out of alinement with the cutting' axis.
2. Inv a pencil Sharpener, a support, a cutter carried by the support and adapted to admit a ,pencil lin the line of the cutting axis, a receptacle removably mounted on the support, a locking key carried ,by` the 1 receptacle havino' two positions in which it is inter-locked with the cutter, vand a guidereducing member carried on said key and carriedthereby from one of said positions in which it is in alinement with the cutting axis tothe other of said positions in which)l it is-out of such alinement.
3. In a pencil Sharpener, a su port, acutadapted to admit a pencil inthe line of the cutting axis, a receptacle removably mounted on the support, a locking key carried b 4the receptacle movably Vinterfl'ocked with7 the cutter, and a guide-reducing member on said Lacasse key and carried thereby into and out of alinement with the cutting axis, said guideil.

5. In a pencll Sharpener, a support,a cutter carried by the support and adapted to, admit a pencil in the line of the cuttingaxis, a receptacle removably and rotatively mounted on the support, a locking key carried by the receptacle movably inter-locked with the cutter, and a guide-reducing memf ber on said key and carried'thereby into and out of alinement with the cutting axis, engagement of the key 'with the cutter beging through the medium of an annular groove in the latter, whereby the key may 'interlock with the cutter in different angular positions of the receptacle. i
6. A pencil Sharpener comprising a support, a cutter havingan opening to receive a pencil in the line of the cutting axis, a plate mounted to slide in a line intersecting the cutting axis, and' a guide-reducing member on said plate, carried thereby to and from position in alinement with the cutting axis; said guidereducing member being depressed to cause it to seat in the opening of the cutter and thereby retain it in alinement with the latter.
