6 Claims. (Cl. 101-369) This invention relates to printing devices of the kind comprising a frame and a printing plate having type characters embossed thereon and detachably mounted on the frame. The most common use of these devices is for printing addresses for mailing purposes and some users have lists of a great many addresses which require a corresponding number of printing devices. The frame of this type is provided with retaining devices and the plate is mounted on the frame by a sliding endwise movement in engagement with the'retaining devices. Wh le this operation may ordinarily be accomplished easily and rapid- 1y, as required by those users who have an extensive mailing list, the leading end of the plate sometimes catches in the retaining devices, particularly at the beginning of the sliding movement, and interrupts the movement and presents a difliculty which is not only annoying to the operator but involves a material delay.

The object of the invention is'to overcome this difiiculty by providing a novel printing plate which will not catch in the retaining devices of the frame and which can be easily and quickly mounted thereon.-

And a further object of the invention is to provide a printing plate having sinuous or serpentine top and bottom edges with square or straight edged ends to facilitate the insertion of the printing plate in the retaining devices of the frame and to enable the plate to be inserted with either end as the leading end.

-In the accompanying drawing,

Fig. 1 is an elevation of a selected printing device'including a plate embodying the invention.

Fig. 2 s'hows' the plate in initial position with respect to the frame for sliding engagement with the retaining devices on the frame.

Fig. 3 is a view similar to Fig. 2 showing the plate partially inserted in the frame.

Referring to the drawing, 4 illustrates one kind of frame with which a printing device of this invention may be used. The frame shown is made of sheet metal and provided with a bottom bead 5, yieldable locking tongues 6 and a plurality of spaced retaining lips 7 disposed in alignment longitudinally of the frame and above the locking tongues.

The plate 8.hassinuous top and bottom edges 9 between its end portions and these end portions are squared with straight top and bottom edges 10 and preferably straight end edges '11. The corners are cut away at 12 to avoid the sharp corners which would otherwise be presented by the juncture of the straight edges 10 with the The top of the nodes plate, and the bottom of the sinuses at the top edge of the plate are in a plane with the straight edges 10 at the top of the plate. The top of the nodes-at the bottom edge of the plate are in a plane with the straight edges 10 at the bottom of the plate and the bottom of the sinuses at the bottom edge of the plate are in a plane above the plane of the straight edges at the bottom of the plate. Another way of describing the plate is to say that it has a straight top edge with rounded projections and a straight bottom edge with rounded recesses. The length of the straight edges 10 at the ends of the plate maybe varied according to the structure of the frame and the retaining devices thereon but it willprdinarily be sufiicient to make them of such length that the end of the plate may be engaged with the top and bottom retaining devices. 7

The proper mannerv of inserting the plate in the frame is illustrated in Fig. 2. The plate is arranged in alignment with the frame with its end portion overlying the locking device at the adjacent end of the frame and with the lower straight edge 10 of the plate at the leading end thereof engaged with the bead-5. It is not necessary that the plate should overlie the frame initially as much as shown in Fig. 2 but it is permissible to do so and just as easy and facilitates the operation. In this position the top corner and top straight edge of the leading end of the plate are clear of the adjacent retaining device 7 but the straight edge at the bottom of the leading end of the plate is engaged with the bead. This initial engagement may be accomplished by a lengthwise movement of the plate but it is more easily accomplished by a downward movement of the leading end of the plate to carry the bottom straight edge into engagement with the bead. Having initially engaged the plate with the frame as shown in Fig. 2, the plate maybe slid lengthwise onto the frame without any part of the plate catching on any of the retaining devices and without any interruption of the movement. This result is due primarily to the fact that the straight edge at the bottom of the leading end of the plate will move freely in the continuous bottom bead 5 and so also will the'nodes of the bottom edge of v the plate as the movement proceeds; and also due to the fact that the straight edge at the top of the leading end of the plate clears all of the top edge of the plate slide freely in these retaining devices. The other end of the plate may be inserted at the other end of the frame in the same manner heretofore described. When. the plate has been slid into its proper position on the frame, the locking devices 6 engage the ends of the plate and hold it in place against lengthwise movement.

Instead of arranging the plate in alignment with the frame initially for the insertion operation, in substantially the manner shown in Fig. 2 which I recommend as the better way of doing it, the plate may be engaged in initial position with the frame as much as shown in Fig. 2 but in inclination to the frame and then straightened out to alignment with the frame as the sliding movement proceeds and in this movement the upper edge of the leading end of the plate clears the top retaining device and the bottom edge of the leading end of the plate is engaged with and guided in the bottom head of the frame in the same manner as heretofore described.

The top edge of the plate is easily distinguished from the bottom edge of the plate because the top edge has projecting nodes and the bottom edge is recessed and this greatly facilitates the work of the operator who embosses the type characters on the plate. The plates are reversible end for end for the embossing operation and they may be inserted from either end of the frame.

It is customary to provide a frame of th s kind with an information card 15 bearing the impression of the type characters on the printing plate and this card is detachably mounted on the frame above the printing plate in any suitable manner.

I have shown and described the invention in a printing device of a kind well known in the art but I do not restrict the invention to this particular embodiment for the invention may be embodied in other printing devices and I reserve the right to make such changes in the form, construction and arrangement of parts as may be necessary or desirable for this purpose or otherwise within the scope of the following claims:-

I claim:

1. A printing plate adapted to be engaged with retaining devices on the frame of a printing device and having the intermediate portions of its top and bottom edges formed with alternate sinuous projections and recesses and the end portions of the top edge and the end portions of the bottom edge formed respectively in straight lines, the corners of said plate being cut away, the end portions of the top and bottom edges leading from the endmost projection or recess to the adjacent cutaway corner of the plate.

2. A printing plate adapted to be engaged with retaining devices on the frame of a printing device and having each longitudinal edge formed with straight end portions and intermediately with a succession of sinuous recesses and nodes, the tops of the nodes at one edge being tangent to the straight line in which the straight portions of that edge lie and the bottoms of the recesses at the other edge being tangent to the line in which the straight end portions of that edge lie, the corners of said plate being cut away.

3. In a printing device which has a frame having retaining means on one face thereof adapted to engage and guide the bottom edge of a printing plate slid longitudinally therealong from one side edge of the frame, said frame also having retaining means on one face thereof adapted to engage the top edge of the printing plate, the combination therewith of a printing plate having sinuous top and bottom edges on the intermediate portion thereof and straight top and bottom edges at end portions thereof, the tops of the nodes of the sinuous edge at the bottom of the plate being in the plane of the straight edges at the bottom of the plate whereby when the straight edge at the bottom of the plate at the leading end thereof is squarely engaged with retaining means for this edge said plate may be directly slid into said frame and the top and bottom edges thereof uninterruptingly engaged with the retaining means therefor to secure said plate on said frame.

4. In a printing device which has a frame having retaining means on one face thereof adapted to engage and guide the bottom edge of a printing plate slid longitudinally therealong from one side edge of the frame, said frame also having spaced aligned retaining means on said face thereof adapted to engage the top edge of the printing plate, the combination therewith of a printing plate having sinuous top and bottom edges on the intermediate portion thereof and straight top and bottom edges at the end portions thereof, the tops of the nodes of the sinuone edge at the top of the plate being in a plane above the straight edges at the top of the plate, the tops of the nodes of the sinuous edge at the bottom of the plate being in the plane of the straight edges at the bottom of the plate whereby when the straight edge at the bottom of the plate at the leading end thereof is squarely engaged with the retaining means for this edge said plate maybe directly slid into said frame and the top and bottom edges thereof uninterruptingly engaged with the retaining means therefor to secure said plate on said frame, the leading edge of the plate at the top thereof clearing the spaced aligned retaining means for this edge of the plate to insure uninterrupted insertion of the plate.

5. In a printing device which has a frame having transversely extending retaining means on one face thereof adapted to engage and guide the bottom edge of a printing plate slid longitudinally therealong from one side edge of the frame, said frame also having spaced aligned transversely extending retaining means on said face thereof adapted to engage the top edge of the printing plate, the combination therewith of a printing plate having sinuous top and bottom edges on the intermediate portion of the plate and straight top and bottom edges at the end portions of the plate, the tops of the nodes of the sinuous edge at the top of the plate being in a plane above the plane of the straight edges at the top of the plate whereby the leading straight edge at the top of the plate clears the retaining means for this edge of the plate as the plate is slid into the frame after the leading straight edge at the bottom of the plate has been squarely engaged with retaining means for this edge of the plate to thereby position the top and bottom edges of the plate parallel with the transversely extending retaining means and therefore expedite insertion of the plate therein.

6. In a printing device which has a frame having transversely extending retaining means on one face thereof adapted to engage the bottom edge of a printing plate slid longitudinally therealong from one side edge of the frame, said frame also having transversely extending retaining means on said face thereof adapted to engage the top edge of the printing plate, the combination therewith of a printing plate having a sinuous bottom edge on the intermediate portion thereof and straight bottom edges at the end portions of the plate of sufficient length to prevent rocking of the plate when the straight edge at the leading end of the plate is squarely engaged with the retaining means for the bottom edge of the plate to thereby position the plate with the top and bottom edges thereof parallel with the transversely extending retaining means.
