IMFRQVEMENT l N PENCIL-CASE ATTACHMENTS To sLATEs Specification forming part of Letters Patent N0. 177,5S9, dated May 16, 1876; application filed March 20, 1876.

To all whom it mag concern:

Be vit known that I, WILLIAM E. Tuoiuns,

of-Fords Store, in the county of Queen Anne and State of Maryland, have invented a new "and Improved. PencilrOasc Attachment to Slates; and I do hereby declare that the following is a full, clear, and exact description 'of thesame.

' i The invention is an improvement in the class of pencilcase attachments for frames of drawing-slates which'consist of atube pivoted at one end in-arecess orcavity of the frame.

p The improvement relates to an attachment formed of a tube open at each end, and hinged,

'on the side to a rod,which spans the recess in the frame, whereby, when the tube is closed, it is held by friction of its side with the side wall of said recess, as hereinafter described.

In the accompanying drawing, forming part of this specification, Figure 1 represents a plan view of aslate provided with my'im. provement, and Fig. 2; is a cross-section on line a: w ofFig. 1.

rod, D, is secured to the said bar in such manner as to span or bridgethe same length-- wise. The tube A is connected to the rod D by a hinge-joint, so that it may be turned thereon. It is open at each end, to permit convenient insertion and removal of the pencil,

and the latter is held in the tube while in the recess 0 by reason of the ends of the tube abuttii] g the end walls of the recess, as shown. The tube is itself held in therecess by friction between their respective sides, which come in contact; but it is apparent that for this result the tube must be of such diameter as to fit tightly between the rod D and longer side of the recess. [11 other woids, the degree of friction corre.-' sponds to the pressure of the rod on the tube. It is likewise obvious that it at any time the friction should become too slight to hold the tube in place, the difficulty may be removed by bending theroad inward, to cause it to press more firmly on the tube.

When it is desired to remove a pencil from the tube, it is requisite, or at least the most convenient method, to tilt the slate-frame,

thus causing the pencil to slide out at that end of the tube which is lowest.

This attachment does not preceptibly weaken the slate-frame, nor increase the size 'or bulk of the same, nor ,add materially tovthe first cost of the slate, while it constitutes a safe repository forpencils, which is always convenient of access.

What I claim is w The pencil-tube open at each end, and hinged on the side to the rod spanning the recess in the frame, as shown and described, whereby. it is adapted to turn laterally on said rod, and be held by friction produced by the pressure of said rod, in the manner specified.

The above specification of my invention signed by me this 9th day of March, A. 1). 1876. I

' W. E. THOMAS.
