7o all whom 'Lt may concern:

lic it known that I, -hummm Hess, Jr., a citizen ot thelfy United States, residing at Troy, county of?, Rensselaer, and State of JNew York, have invented certain new and useful Iinprovements in rllalking'-Machine llorns, oiwhich the following is a specilication. Y y

The invention relates rto such improvementsand consists ot' the novelyconstruction and combination.of` parts hereinafter described and subsequently claimed.

liclcrence may be had to the accompanying drawings, and the reference characters marked thereon, which form a. part of this specification. bimilar characters `refer to similar parts in the several figures therein.

Figures l, 2, 3 and 4, are sectional views illustrating successive steps in the securing together ot' plies of cloth in the manufacture of my improved phonograph-liorn. Fig. 5 is a central, vertical, longitudinal section showing the cloth-body stretched upon a horn-shaped form. Fig. 6 is a plan view of one of the segmental blanks of 'cloth used in the manufacture of the horn.l Fig. 7 is a view in side elevation of the horn with a portion of the edge broken away and shown in central, longitudinal section.

The principal object of my invention is to produce a souiid-strengthening device adapted for use in, or in connection with, musical .and sou11d-reproducing instruments.

Other objects of the invention will appear in connection with the following description.

I have shown, and will describe, my invention in its preferred application to the horn of a sound-reprcxlucing instrument; but itI is also adapted for use in any case where it is desired to reflect and strengthen Sound vibrations.

The invention consists in a body ofthe desired shape made up of a plurality of plies of cloth sti'ened and bound together by a suitable cement or size. y,

Referring to the drawings wherein the, invention is shown in preferred form, 1, represents a phonograph-horn embodying my invention and made in accordance With my improved method. In making such a horn I preferably cut from a web, or Webs of cloth a number of plies, 2, of substantially the form shown in Fig. (3 of the drawings, each blank being approximately a quarter-segment of a phonograph-horn of the desiredA size. I then superpose one uponanother a number lof said blanks, double thatof the numberof plies ot' which the horn isto be made, and secure all.' of vsaid plies together along one edge, from the tapered-to the liared end of the horn,by a line ot stitching,

Specification of Letters Patent. Patented Jani i7, 1911.

3,' after `which I apply to the edges lso stitched together a bindinOr strip, 4, one edge of which is first secured by a line of stitching, 5, as shown in Fig. 2, after which the `other edgeissecured bya line of stitching,r

t3, as shown in VFig. l have shown. in Figs.

1,2 and 3, eight. plies or blanks thus secured together along one edge, it being desired to produce a horn tour plies in thickness. After'the plies have been thus secured together along one edge, they are opened out between the fourth and tit'th plies and four additional plies are applied to each of the four plies so separated, and the edges of each eight plies thus formed are secured together in the manner above described. The unsecured edges oli' the additional eight plies are then secured together in the same manner completing the inclosure adapted to be made into a horn. The bdy thus formed is then saturated' with starch and is drawn or" stretched over a form of the proper size and d .sired shape and permitted to shrink anddlfy thereupon. A preferred manner of saturating the fabric with `starch is to immerse the fabric in a hot liquid solution of cooked starch until the starch has penetrated to all parts of the .fabric and tilled the interstices thereof. Vhen the starch has become dry and hard, the plies -will be firmly bound together into a practically solid body which will be hard and stitt and adapted to retain the shape imparted by the itorm. The body thus'formed comprises substantially a homogeneous body of hardened starch supported by the plies of fabric embedded therein. After the horn has been thus formed', its end edges are trimmed and covered with a binding strip, 8, which may be an ordinary piece of tape glued or cemented thereupon. At each of the four longitudinal seams a stitfening rib is 'formed by the stitched-together edges of the plies and the binding strip applied thereto, so that great strength is given to the structure. Any desired eement or sizemay be employed; and the quality lor timbre o't the sound rellected or transmitted by the horn can be varied by varying ythe kind and consistency ot' the cement, as Well as by varying the number of plies of cloth lof which the horn is made.

Ivhave shown and described a preferred construction of horn, but I do not wish to be limited thereto, as the manner of constructing the device can be varied in accordance with the use to which the device is to be put and the wishes of the maker or user.

lhe body of the device may be made up of plies of any desired kind of cloth, knitted or Woven, but I prefer to use ordinary woven cottoncloth.

The shape and size of the device can be varied in' accordance with the conditions to which it is to be subjected in use.

, therein, and saturated therewith, a plurality pf plies of cloth,

2. A sound-strengthening horn formed of a plurality of segments each comprising a, plurality of plies of cloth sewed toget ier alon their neighboring edges, and stilfened and ound together by cement.

3. A sound-strengthening horn formed of a plurality of segments each com rising a. plurality of plies of cloth having tie neighboring edges of adjacent segments secured together by e stitched seam, and said edges covered by n binding strip, the several plies being stitfened und bound together by cenient.

In testimony whereof,I have hereunto set my hand this 5th day of July, 1906.
