The plate Figure 5 is asectional view of the device shown i'i iS heid against being Slidably removed from in Figure 4, taken on line 5--5 and looking in the the grooves .by the 10We1 edge oi the top pieee i2 50 direction ofthe arrows; and serving as an abutment and by means of thev Figure 6 isa view of one form of devicesuitable upper edge 0f the .Diete I8.

for releasing the holding means shown in Fig- On the back near the lower edge of the plate nre 4, IB, projections 32 are formed Whichvare adapted 55 Referring now to the drawing in which I illusto fit into notches '33 formed vin the bottom rail i3. By means of screws 34 passing through the projections 32 and into the bottom rail the plate E8 is held in position. Being thus located the screws are usually below the level of the eye and therefore inconspicuous and relatively concealed.

From the foregoing, it will be understood that any suitable advertising legend may be pasted, printed or otherwise displayed on the plate Il, and that such advertising legend may be changed from time to time by removing the screws 34, withdrawing the plate I8 and thereafter removing the plate Il and substituting therefor a similar plate carrying other advertising.

The lower part of the front surface of plate I8 is treated in any suitable way to form a surface 35 upon which matches may be struck, such for instance as having cemented or otherwise secured thereon a suitable composition or indeed roughening the surface of the plate itself. The remainder of the surface of the plate I8, is'such that memoranda may be written thereon and easily erased by any suitable means, such as by a. damp cloth.

In the construction of my device, I preferably mold the plates I1 and I8 of a suitable plastic material, but it will be understood that any other suitable material may be used, such for example as any suitable paper means or paper board having a suitably prepared surface.

Referring now to Figures i and 5, in which parts similar to those above described are indicated by similar characters, it will be seen that instead of the projections 32 and screws 34 for retaining the plate I 8 in position, I provide means entirely concealed behind the plates, such for eX- ample as a notch 38 formed in the back of the plate iS adapted to cooperate with the upper end of a leaf spring 39 secured in any suitable way to the back of the lower rail i3 or confined between said rail and the frame support. The front portion of the lower rail I3 over the hole 21 in the modification shown in Figure 4 is cut out as at 40 to provide a rectangular aperture through which a tool such as shown in Figure 6 may be inserted from a point outside the frame, and by which the spring E9 may be pressed away from the plate I8 and out of engagement with the notch 38 and permit the same to be withdrawn. One advantage of this method of securing the plate I B in the device is that it is less obvious how the plate may be removed and particularly how the spring 39 may be moved to inoperative position and thus prevent the removal of the plates l1 and I8 by persons not authorized to do so. It will be understood that the device shown in Figure 4 may be assembled by pushing the plates I7 and I8 into the grooves as above described until the spring 39 drops automatically into the notch 3B, a position which may be described as their home position.

While I have described what now seems to be the preferred embodiment of my invention, it is conceivable that various modifications in the configuration, composition and disposition of the component parts going to make up the same may occur to those skilled in the art, and that various changes in the form, proportion and minor details may be resorted to within the scope of my invention.

What is claimed is:

1. A memorandum device comprising in combination a pair of plates at least one of which is made of material from which memoranda recorded thereon may be erased, a frame therefor adapted to be mounted upon a support; said frame having groove means for slidably receiving and retaining in place said pair of plates when the same are disposed edge-to-edge therein, and an aperture; and clamping means cooperating with the front surface of one of said plates disposed between the abutting edges thereof, in combination with means for holding said plates in position in said frame to prevent the withdrawal thereof and confine said clamping means between said plates, said holding means being concealed behind one of said plates and comprising spring means mounted upon said frame adapted to be moved into inoperative position by an instrument inserted through said aperture.

5. A device of the class described comprising plate means having a surface suitable for recording memoranda thereon and from which the same may be erased, in combination with means for mounting said plate means upon a support, said mounting means comprising a frame having a top piece adapted to serve as an abutment for said plate means, and a side rail depending from each end of said top piece provided with a groove open at the bottom between which said plate means is adapted to slide and be retained thereby with the front surface of said plate means and front surface of said side rails and a portion of said top piece disposed in a common plane, and means for retaining said plate means in position surface of one of said plates disposed against said abutment, said retaining means comprising a'notch in the backL of said plate means and a leaf spring mounted on said frame adapted to cooperate with said notch.

6. A device ofthe class described comprising plate means having a surface suitable for recording memoranda thereon and from which the same may be erased, and means for mounting said plate means upon a support; said mounting means comprising a frame having spaced groove means between which said plate means is adapted to slide and be retained thereby, and an aperture; in combination with means concealed by said plate means for retaining thesame in position, said retaining means comprisinga notch in the back of `said plate means and a leaf spring mounted on said frame adapted to cooperate with said notch and being operable from a point outside of said frame through said aperture.
