M 8 DAVID L.MORRISON,

Patented Aug. 14, 1945 UNITED STATES PATENT OFFICE 2,382,804 MUSIC CHARACTER PRINTING David L. Morrison, Bloomfield, N. 5.

Application March 28, 1944, Serial No. 528,382

3 Claims.

This invention relates in particular to a device for manually printing musical symbols or charactors, for example notes, sharps and flats, and one object of the invention is to provide such a device which shall include novel means for accurately locating or positioning and aligning the characters horizontally and vertically relatively to each other and to the lines of the musical staff. However, more generally an object of the invention is to provide similar means in other devices for relatively positioning or alining other characters, symbols or elements which are to be placed in contact with a surface.

Another object of the invention is to provide a device of the character described which shall mbody novel and improved features of construction such that the characters can be printed rapidly and clearly and with a minimum of physical and mental strain.

A further object is to provide a novel and improved combination of manually operable means for printing a character or symbol and means for orienting the character or symbol in a desired or proper relation to other previously printed symbols or other inscriptions, indicia or marks, whereby the printing means can be positioned and accurately held at a desired point with the character properly oriented and the character or symbol can be accurately printed while the printed means is so held.

Other objects are to provide such a devic which shall include means for depositing, impressing or imprinting upon a-surface an element which is invisible during the depositing, impressing or imprinting operation, and novel and improved means for indicating the position of said element relative to said surface or other elements, impressions or prints thereon; and to obtain other advantages and results that will be brought out by the following description in conjunction with the accompanying drawing in which Figure 1 is a perspective view of a device constructed in accordance with my invention showing the manner of using it.

Figure 2 is an enlarged central vertical sectional view through the lower end of the device shown in Figure 1, showing the parts in normal position.

Figure 3 is a similar view showing the position of the parts during a printing operation.

Figure 4 is a top plan view of the device as illustrated in Figure 3 on a somewhat reduced scale.

Figures 5, 6 and '7 are bottom plan views of the device showing different printing elements, and

Figure 8 is a view similar to Figure 1 showing a modification of the invention.

Attached to the other end of the barrel 2 is one end of a block or bushing 4, the other end of which has a sleeve 5 separably attached thereto as by screw threads 6. The sleeve 5 constitutes a retainer for an element such as a printing memher that is to be positioned or pressed into contact with the surface.

In the specific embodiment of the invention, said element is formed to print a desired symbol or character, particularly amusical character or symbol such as a note, sharp or fiat. The element is shown as comprising a. plate I of suitabl material, for example metal, to one side of which is secured a rubber stamp 8. The plate I is slidably mountedin the sleeve 5 and has a circumferential flange 9 to cooperate with an internal shoulder ill on the sleeve for preventing movement of the plate completely out of the sleeve. A compression spring II is interposed between the plate and the block 4 normally to cause the stamp 8 to be exposed through the end of the sleeve as shown in Figure 2, and at the same time permit the stamp to yieldingly retract upon pressure of the stamp against a surface to be printed.

Cooperating with the holder A and the printing element 1 is a locator pin I2 which is longitudinally slidably mounted in an opening IS in the block 4 and through an opening I4 in the the printing element I. One end of the locator pin 12 is pointed at l5 and normally projects beyond the printing element as shown in Figures 1 and 2, and the other end of the pin has a head l6 which limits outward movement of the pin and between which and the end of the shank is interposed a compression spring I! for normally projecting the pin from the printing member but permitting the pin to yieldingly retract as it is pressed into contact with a surface. Desirably the head l6 of the locator pin may have a finger piece I8 projecting through a slot l9 in the barrel 2 for manual retraction of the pin where desired, as when the stamp 8 is pressed into contact with a stamp pad.

In the operation of the device so far described, the rubber stamp 8 will conform to one of the characters or symbols to be printed, in the prescut instance a whole note, and the locator pin projects in predetermined relation to the stamp. When it is desired to print the character, the stamp 8 is pressed into contact with an inking pad as usual, whereupon the point Ill of the locator pin is pressed into contact with the surface to be printed at the place where it is desired to make the impression of the stamp as shown in Figure 1. Thereupon the shank l is pressed downwardly to cause the stamp 8 to contact with the surface being printed as shown in Figure 3, the printing element retracting against the influence of the spring II to ensure a clear impression. During this operation the pin IE will guide the holder and prevent lateral slipping thereof, and the pin will retract as shown in Figure 3.

Another feature of the invention is means for orienting horizontally and vertically relatively to the surface to be printed, the element, 1. e. the stamp 8 to be placed into contact with the surface. As shown, this means comprises a finder pin 26 projecting laterally from each of diametrically opposite sides of the block 6 and at least one other finder pin 2i projecting laterally from the block perpendicularly to the pins 2%. The pins iii and 28 have a predeteed relation to the printing element, and to positively locate the printing element in predetermined relation in the holder, the plate ll may he formed with a flat surface 22 on its edge to engage a corresponding flat surface 23 on the inner surface of the retainer sleeve 5. Preferably the surfaces 22 and 28 will bearranged at the top of the printing element as will also the pin 29, while the other pins 28 will project at the sides of the printing element.

Accordingly, when the printing element represents a musical character, during the printing operation the point it of the locator pin will be located on the space or line of the musical stat! B at the point where it is desired to print the character. Then the pins will be located by turning the holder so that they are parallel with the lines of the staff and the pin 2! will be located at the upper side and perpendicular to the lines of the staff, all as shown in Figures 1 and 4. Then the printing element may be pressed into contact with the surface on which the musical staff is printed as above described.

Conveniently the rubber stamp may be in the form of a whole note as illustrated which may be changed to a half note by adding a tail with an ordinary pen and may be changed to a quarter note, an eighth note, etc. by filling in the whole note character and adding a properly marked tail.

The construction and combination of the retainer I and the printing element makes it possible to easily and quickly mount and remove the printing element on and from the holder respectively, and various printing elements can be easily and quickly interchanged. Thus one printing element may represent a ledger line as indicated at 24 in Figure 5, and other printing elements may represent sharps and flats as indicated at 26 and 21 in Figures 8 and I.

when the ledger line printing element is utilized, the locator pin 12 will be spaced from the rubber stamp 24 representing the ledger line a distance corresponding to the spaces between the lines of the musical stafl. and in printing the ledger line the locator pin will be placed on the top or bottom stafl line or the next adjacent ledger line with the pins 20 located with respect to the staff lines as hereinbefore described. when the ledger line is printed above the stall, the pin 2| will be located at the top side of the holder as shown in Figure 1, while when printing the ledger line below the stall the finder pin 2| will be located at the underside of the holder.

If desired, a printing element may be arranged at each end of the holder as shown in Figure 8, for example the holder C may have a ledger line printing element 24 at one end thereof and a printing element for one of the other characters such as hereinbefore described at the other end.

Other modifications and changes in the details of construction and in the use of the devices will occur to those skilled in the art as within the spirit and scope of the invention.

What I claim is:

1. A device of the character described comprising a manually operable holder, a marking element mounted on one end of said holder to he placed in contact with a. surface and being invisible durlng the marking operation, a locator pin projecting longitudinally from said end of the holder centrally of said marking element to engage said surface at the point where contact of said element with said surface is to be made, said pin being yieldingly retractable into said holder as it is pressed against said surface, and indicators projecting laterally from said holder in predetermined fixed relation to said element for orienting said element horizontally and vertically relatively to said surface.

2. The device set forth in claim 1 wherein said indicators comprise finder pins one projecting from each of opposite sides of said holder in alinement with each other and at least one projecting from said holder perpendicularly to the first-mentioned pins.

3. A device of the character described comprise ing a plate having a printing element thereon, a

rod-like handle having a barrel at one end, a

sleeve separably attached at one end to said barrel, said plate being mounted within said sleeve so as to expose said printing member at the other end of the sleeve, said sleeve and said plate having cooperating portions to hold said plate against displacement through the second-mentioned end of the sleeve and said printing element being invisible during a printing operation, said plate having a central hole, and a locator pin slidably projecting through said hole and yieldingly retractably slidably mounted in said barrel to engage a surface at the point where an impression of said printing element is to be made.
