Patented May 27, 193() REBECCA E. HoorER, or HALE Moon BAY, cALIEoENm i MEMORY Y rAn Application filed November 14, 1927.` Serial No. 233,230.

My invention relates to improvements in memory` pads, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a memory pad that has means for covering a portion of the work, causing the student tot recall from memory the portions of the work thus covered and which has means for advancing the work covering shield sothat an entire sheet of paper may be systematically gone over in order that by constant repetition the necessary problems will become memorized. The device maybe used for all kinds l "V of problems, the learning of shorthand being one of the special uses to which the device may be put.

The invention employs several features which differ from other devices nowon the market. A guide for a ruler is so mounted that this guide may be moved vertically with respect to the pad. I term this member a Heating guide. The second feature is the provision of a stop for the ruler that-may be 5 swung into inoperative position when it is desired to remove the ruler from the topmost sheet of the pad in order that this sheet may be torn from the pad. A third feature resides in the posts which perform a double function. These posts clamp a pad of any thickness within predetermined lines to the suppor, andalso act as uprights for the floating u1 e. h Other objects and advantages will appear in the following specification, and the novel features of my invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this ap- 0 plication, in which:

Figure 1 is a top plan view of the device; Figure 2 is a section along the line 2-2 of Figure 1; and

Figure 8 is a section along the line 3-3 of Figure 1.

In carrying out my invention I provide a supporting back 1 that can be made of any desired material that is strongl enough to withstand ordinary school use. To this support I secure posts 2, the posts or uprights being disposed at the rightand left hand up* per corners of the support. These posts have heads 3, seeFigure 35 that prevent the posts from being withdrawn from the support 1.

VThe posts are threaded for receiving knurled Vnuts 4. Sleeves 5 are also mounted upon the `posts 2 and bear against a strip 6 that clamps a pad `7 to the supportl.

Itrwilly also be noted from Figure 8 that the postsV not only passthrough slots 8 in the support 1, but pass through openings 9 in a `metal strip 10 that is disposed at the back of the support, as Ashown in Figure 2. A tightening of the nuts 4 will cause the sleeve 5 to clamp the strip 6 down against the pad 7 i i A ruler 11 extendsat right angles from the strip 6 and is mounted upon a carriage 12 that has rollers 13 for slidably receiving a floating guide member 14. Theruler has perforations 15 for receiving the point of a pencil whereby a movement of the ruler will draw a line upon thepad 7. Additional perforations 16 may be disposed at spaced intervals, such as, for example: one inch` apart. A scale is also stamped upon the rulerand `is indicated by the reference numeral 17. v

The strip 6 also has a scale' 18 thereon. Figure 3 shows how the member 14 mounted upon the collars 5 so as to automatically adjust itselfat the desired height `above the pad 7. i i

The strip 10` carries a clip 19 for receiving a pencil 20. The bar 14 carries a grooved collar 21 that is slidably mountedon the sleeve 5. `This collar rotatably receives a stop 21 that is adapted to enter a recess 22 in the carriage 12 whenthe stop is disposed in the position shown in Figures 1 and 3. This prevents the ruler from being moved off the pad. The stop maybe swung about the collar 21. When the stop is swung to the left the carriage 12 may be moved so as to receive the post 2 in the slot 22. The carriage will carry the ruler 11 clear ofthe pad 7. This permits a sheet to be torn from thepad, if desired. The purpose of the stop is to keep the carriage from `riding `olf from the pad. This makes it easy for the studentA to quickly move the ruler over the surface ofthe paper Without is slidably any chance of the ruler becoming engaged with the edge 24 of the pad.

A shield indicated by the dotted line in Figure 1 is removably secured to the ruler 11 by clips 26.

From the foregoin description of the various parts of the dev1ce,tl1e operation thereof may be readily understood.

A pad of any desired thickness maybe secured to the support 1 b the stri 6 and the posts and nuts 2 and 4s. f desiY the shield 25 ma be dispensed with and the ruler` 11 used or the drawing of a number of lines upon the uppermost sheet of the pad 7. The scales 17 and 18 permit these lines to be drawn in a predetermined manner.- If it is desired to draw lines at an angle over the pad 7 the pad may be swung into the desired angle and then be clamped in place.

gg The device is especially adapted fermemory workand when used in this connection the shield 25 is secured to the ruler 11 by the clips 26. At 27 I have shown shorthand characters and words representing these characters. The student would Write the words but, can, and it after glancing at the shorthand characters in the row 28. The row 28 would then be covered by the ruler 11 and thon the shorthand characters would be Written in the row 29.- Any number of rows may be provided in this Way, and the ruler advaneed to cover each row in order that the student may ix firmly in mind the various characters represented by the words.

REBECCA E. HOOPER.

I have already shown a problem at 30 which shows another use for the pad. The device may be used for purposes other thanthose shown, as for example: thedevice may be used as an ordinary composition tablet in which lines have been previously drawn on the paper b inserting the point yof a encil in any one o the desired openings 15 an movt e ruler 11 transversely across the pad.

Although I have shown and described one embodiment of my invention, it is understood that the same is susceptible of various changes and I reserve the right to employ such changes as may come within the scope of the app en I claim:

1. A device ofthe type described, comprising a. support, uprightscarried by said support, means carried by said uprights for clamping apad to said support, a floating guide bal* slidably carried by said uprights, a stop carried by one of said uprights, a ruler, means fo slidably connecting said ruler` to said gide bar, said stop normally preventing the movement of said ruler o from the pad, said stop being movable into inoperative po; sitn for' permitting the ruler to move olf from the pad.
