Specification of Letters Patent.

Patented Nov. 18, 1913.

To all whom it may concern:

Be it knownthat I, ERNEs'r G. CLARK, a citizen of the United States, residin at De Kalb, in the county of Dekalb and Illinois, have invented new and useful Improvements in Note-Sheet Terminals, of

erence being had to the accompanying draw- 'ings, forming a part thereof.

The purpose of this invention is to provide a convenient form of terminal lug for a perforated note sheet such as is used in automatic piano players, and the like.

It consists of the features and elements described and shown in the drawings as indicated in the claims.

In the drawings :'F igure 1 shows the device applied to a note sheet and in usev for coupling the same to the feed roll of a player action. Fig. 2 is a rear view of the device. Fig. 3 is a section taken; as indicated at line' 3- 3, on Fig. 2-.

As illustrated inthe drawings, this device consists of a tab made from linen or other suitably tough fabricand having the form of an isosceles triangle, 1, of which the two equal angles, 1, are blunted or rounded, and the odd angle or apex is extended to form the lug, 1*; this lug is perforated and has secured in it an eyelet, 2, which also engages the lug, 3 of a smaller tab, 3, which is also made in the form of an isosceles triangle with its corners, 3 rounded, but positioned with its base, 3, below the base, 1, of the larger triangle and parallel thereto.

The interior or proximate faces of the two tabs or leaves of the device are gummed,

so. that they may be readily applied to the opposite surfaces of a note sheet, A; this adapts the device to serve as a terminal fitting for the note sheet for coupling it to the driving roll, B, of theplayer action, by engagement of the eyelet, 2, with the pin, B positioned thereon. The tab being constructed of fabric instead of paper, has more tenacity than the sheet itself and is better adapted to contain the eyelet or any device intended to engage the driving pin, B By virtue of its triangular form, it serves to distribute the tensile strain from the eyelet toan area of the paper great enough. to withstand such strain. Since practically none of such tensile strain could be transmitted to the-'oaper-"lyi-ngdirectly tate of at either side of the tab,.the corners of the tab together with their respective lugs, are

all formed from a single piece of fabric folded along the line, 5; it is obviously im material, however, whether one piece or two be used in.this construction, since both tabs are securely connected by the engagement of the eyelet with their respective lugs.

By virtue of the fact that thetab, 3, is

'smaller than the tab, 1, the total thickness of the note sheet varies gradually rather than abruptly, .as it would along the line,

1, if the tabs-were of equal size, and this graduated thickness renders less likely any breaking of the paper along this line, such as would tend to occur in the constant rolling and rerolling of the sheet in use.

line with the respective sides of the triangular tabs which include the aforesaid apex angle.

2. In combination with a perforated note sheet, a terminal tab therefor comprising two leaves of fabric having the. form of isosceles triangles, each with a lug projecting from the apex angle of the triangle, and each having the other two corners of the triangle rounded off in smooth curves blending into the sides and base of the triangle, the mutually facing surfaces of the two. leaves beingsecured to the opposite faces of the note sheet, said note sheet having its lateral edges near itsterminal portion slanted in line with the respective sides of the tabs which include,.-the a-Sex angle, and an attaehing devic'e carrie by the lugs.

3. In 1comlo'i'nation with a erforat-ed note sheet, a. terminal tab there or, comprising two leaves of fabric having the form of isosceles triangles, each with :1 lug projecting from the apex angle of the triangle, and an attaching device carried by said lugs, said note sheet having the lateral edges near its terminal portion slanted in line with the respective sides of the tabs which include the apex angle and one of the leaves being of less area than the other and havin that portion of its margin which is directly opposite the lug lying within the margin of the other leaf, the mutually facing surfaces of the two leaves being secured to the oppo- Site faces of the note sheet.-

I sheet, a terminal tab there at In combination with a ferfor'ated note or, comprising two leaves or fabric secured, respectively, to

I the oppositefaces of the note sheet and each hcvings lug projecting longitudinallyfrom the end of the note sheet, and an eyelet in said lugs securing them together and adapted to serve for attaching the end of the note sheet to the driving roll of a player mechanism. 7' t 5. A device for the purpose indicated,

comprising two leaves of fabric having each margin of t as other leaf, and t e mutually.

facing surfaces of the two' leaves being gummed for securing them respectively to opposite sides of a sheet which may be inter posed between them.

In testimony whereof I have hereunto set my'hand at De Kalb, 111., this 16th day of May, 1911. I

ERNEST G. CLARK.
