PROVISIONAL SPECIFICATION.
Improved Pencil Sharpener Appliance for Attachment to Frames
of Slates.
I, WILLIAM PECк, of Witham Town, Boston, in the County of Lincoln,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improved pencil sharpener appliance for attachment to
frames of slates.
For the purpose of my said invention, I stamp, punch, or otherwise form a
roughened face either in holes, slits, or their equivalents in straight, angular, or
other arrangement in or on a plate of, say, steel or brass, and bend or fold it
centrally lengthwise between the two sets of holes or the like slightly less than the
width of the frame of a slate, the face edges being bent inwardly to approach the
slate proper so that the article so made can be slipped over and along any part of
the slate frame and hold itself firmly thereon without nails or other fasteners.
I round the exposed corners of the article to prevent abrasion of the fingers.
If it be determined that my grip pencil sharpener be affixed to any particular
part of a slate frame, then the frame could be recessed for the location of the
sharpener as to be flush with the surface of the frame.

COMPLETE SPECIFICATION.
Improved Pencil Sharpener Appliance for Attachment to Frames
of Slates.
I, WILLIAM PECK, of Witham Town, Boston, in the County of Lincoln,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to improved pencil sharpener appliance for attachment to
frames of slates.
For the purpose of my said invention, I stamp, punch, or otherwise form a
roughened face either in holes, slits, or their equivalents in straight, angular, or
other arrangement in or on a plate of, say steel or brass, and bend or fold it
centrally lengthwise between the two sets of holes or the like slightly less than the
width of the frame of a slate, the face edges being bent inwardly to approach the
slate proper so that the article so made can be slipped over and along any part of
the slate frame and hold itself firmly thereon.
I round the exposed corners of the article to prevent abrasion of the fingers.
My invention and its application to a slate frame is represented in the annexed
drawings.
Figure 1 perspective elevation of a strip of steel cr hard brass bent to the

page_text: required shape with holes punched from the inside to present a roughened rasp
like surface on the outside flat portions only, the loop of the bend and the face
edges being plain.
Figure 2 shows a similar bent piece of metal with louvre like projections on the
outer surface, these being cut and stamped up from the inside.
Figure 3 section of same, through line a, b, of Figure 2.
Figure 4 represents a bent strip with longitudinal intercepting slots, the edges of
the slots being turned or curled up to present an abrazed or file like surface on the
outside, as at section Figure 5, this being taken through the line c, d, of Figure 4.
Figures 6 and 7 indicate a bent strip with transverse intercepting slots or slits
and one edge of each slot being turned up from the inside stamping process to
form roughened file like edges.
Figure 8 shows a bent plate or strip with diagonal slite intercepting each other
and with the edges turned up by the stamping or operation to form a roughened
exterior, as at Figure 9.
Figure 10 represents one of my slate pencil sharpeners sprung over the frame of
a slate and into a recess formed in the frame head to lie flush therewith.
It will be understood that my springy and self holding slate pencil sharpener is
applicable to any part of a slate frame and need not be embedded in said frame, it
being necessary when fitting it on and along the frame to any desired part to exert
a pushing pressure for the purpose.
It will be perceived from the foregoing that the article holds itself by its springy
clipping action to a slate frame, no nails or brads being required for locating it.
Another feature of novelty is, the article fits both sides of the frame so that both
faces are applicable for pencil sharpening purposes.
A the sharpener. B the plain bent back. C the roughened surfaces. D, D, the
plain face edges bent inwardly. E slate frame.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of a slate pencil sharpener affixable to a slate frame and
having a roughened face on each side thereof, said sharpener being of a springy
self fitting or clasping character when pushed on and along from either edge, as
described and as shown.
2. A slate pencil sharpener composed of a bent yet springy strip of metal having
roughened surfaces on both faces and curved in edgea to engage with and grip the
moulding or bevil inner edges in addition to the grip of the body part of the
article on and against flat surfaces of the slate frame, as set forth.
