SPECIFICATION forming part of Letters Patent No. 469,593, dated February 23, 1892. Application iiled May 25, 1891. Serial No. 393,974. (No model.)

T0 all whom, it may concern,.-

Be it known that I, GEORGE WV. PATTERSON, a citizen of the United States, residing in the cityand county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Scholars Companions, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in scholars companions, and it consists of the combination of parts, as hereinafter set forth.

Figure l represents a perspective view of a device embodying my invention. Fig. 2 represents a sectional view thereof on line x x, Fig. 3 represents an end view of a modification thereof.

Similar letters of reference indicate corresponding parts in the several figures.

-Referring to the drawings, A designates a ruler formed of a piece of material having a beveled edge, on which is marked a scale of measure B. In the upper face of the ruler is a chamber C, adapted to contain a sponge or other Wiper D for a slate, the said chamber having a pivoted lid E, which is provided with a lip F and a recess G, the walls of the latter engaging a pin H on the ruler. To the said upper face of the ruler is attached a penwiper J, said wiper consisting of one or more strips of suit-able materiahwhich are secured at one end to the said ruler by a metallic strip K, placed on the same and connected with the ruler by a tack or other suitable fastening device.

In the ends of the ruler and extending longitudinally thereinare the chambers or recesses L, adapted to hold slate-pencils, penholders, chalk, Lite. The said recesses are provided With the lids or covers M, each of Which is of thin metal substantially of the form of the end of the ruler and provided with the recesses N, corresponding in outline with 'the edgesof the recesses L when the said lids are turned on their pivotal connections I to open said chambers L. The upper edge of each of the lids M is provided with an inwardly-projecting stop or lip Q, adapted to come in contact With the upper face of the ruler when the lid is closed, thus limiting the closing movement thereof, and the lower edge of the lid has an outvvardly-projecting lip R for convenience in operating the same.

It will be noticed that in operatinga lid M both of the chambers L on one end of the ruler are simultaneouslyopened or closed, as the case may be.

In Fig. 3 is shown a modification Where separate lids S are used for the two chambers L, said lids having a common pivot and each provided with a lip T for operating the same and a recess U, the walls of which abut against apin or stud V in the ruler when the lid is closed as a stop for the same. The chambers are formed, preferably,by boring into the ends of the ruler, producing openings directly in the body of the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y l. In a scholars companion, a ruler having a recessed or depressed portion in the solid portion of the upper face thereof, adapted to contain a sponge, and a lid for said recess, substantially as described.

2. In a scholars companion, a ruler having a sponge-containing recess in the solid portion of the upper face thereof and a pivoted lid therefor provided with a lip adapted to engage a pin on the ruler, said parts being combined substantially as described.

3. A scholars companion consisting of a ruler having two chambers in the ends thereof and a lid covering both chambers, With a pivotal connection between the chamber, Whereby both chambers may be simultaneously opened or closed, as stated.

4. A scholars companion consisting ot' a ruler With chambers in its ends provided With pivoted lids, each having an inwardly-projecting lip adapted to engage the face of the ruler and an outwardly-projecting lip for operation thereof, substantially as and for the purpose set forth.

5. A scholars vcompanion consisting' of a ruler with chambers in its ends, each end being provided with apivoted lid having recesses coinciding with the edges of the said chambers when the lid is opened, a lip projecting inwardly and serving as a stop, and

an outwardly-proj ectin g lip for operating said 10o lid, said parts being combined substantiallyV opens or closes the same, said parts being as described. combined substantially as described.

6. A scholars companion consistinff of a ruler with a scale thereon and providerd with GEORGE T PATTERSON' Witnesses:

5 a chamber in its face having a lid therefor and chambers in its ends, the chambers of JOHN A. WIEDERSHEIM, each end having a lid Which simultaneously A. P. JENNINGS.
