PHQNOGRAPH-HORN.

No. 92e,235

Application filed. August 19, 1907. Serial No. 389,188.

To all wh0m itmdy- -cimcem:

Be it known that I, PAUL B. BERNER, a citizen of the United States, residing in the borough of Brooklyn, city of New York, in

the county of Kings and State of New York, have invented certain new and useful Improvements in Phonogra h-Horns, of which the following is a specification.

This invention relatesto phonographhorns and like instruments, the bells of which are usually built up of a series of sections, the latter generally having curved side edges which give the desired contour to the bell; and in certain respects it is in the nature of an improvement on the horns shown in United States'Patents 12,442 of January :30,

190mm 7 71,441 of October 4, 1904.

One of the principal objects of my invention is to simplify the construction and reduce the cost of the built-up bell of a phonograph horn. To this end, I make the sections of thin flexible sheet. metal, usually with curved side edges, and join said curved edges together by means of wires passing through a series of eyes rolled or formed alternately in the contiguous sections. This method of joining the strips together is very simple and inexpensive. p p A further object of the invention is to produce a horn which is capable of being' folded or reduced in bulk for convenience in trans portation or storage.

lin carrying out this feature of the invention, I preferably form certain or all of said sections of two strips each as hereinafter described. This permits the strips to fold together in the manner of the plaits of a fan, so that all. the strips can pack facewise against each other, thereby reducing the bulk to a minimum. In setting up the horn it is only necessary toexpand the bell, which, owing largely to the outward buckliig of the large ends ofthestrips, possesses su cientrigidity for use.

Preferably each of two sections in the horn is single, that is, formed of a single metal plate instead of being formed of two strips hinged together. These single plates or sections are placed opposite each other in the horn, so that when the same is folded, the strips or plaits form two sets which lie one I Specification of Letters Patent.

Patented June 29,1909.

' opposite the other between said single sectlons, so that the device very closely resembles a folded'fan in form.

intended to be collapsible, all of the sections may be single instead of formed each of a pair of strips hinged together; 'the'n ov'el; method of hinging the sections together even methods heretofore in vogue.

The neck of the bell, whether collapsible or not, may be provided with any suitable funnel or means to connect the same to a phonograph as hereinafter described. i

In the following I have described, in connection with the accompanying drawings, one form ofdeyice illustrating the carrying out of my invention." l

In the accompanying,drawings, Figure l is a view of a phonographhorn embodying my several improvements in one form; parts" being broken away to disclose the invention more clearly. Figs. 2 and 3,are end views of a bell section, comprising two strips hinged together, a1ul illustrates the huekling or springing of the strips when opening the bell. F ig. 4: is a sectional view to illustrate the hinging of the strips which form a bell section. Fig. 5 shows the Fig. at strips separated. Fig. (3 is a blank of one old; strips which make up the bell sections. Fig.

7 is one of the single or main sections of the bell, undivided into strips. Fig. 8 is a viewof another construction of device for clamp ing the neck of a bell. Fig. 9 shows one of the wires which form the pintles to connect the strips and sections together. Fig. l is a view of two strips hinged together to form a section. Fig. 11 is'a view of a de tached opened bell. Fig. 12 shows the bell folded in full lines, and also shows by dotted lines the manner of unfolding the same.

Similar letters and niunerals of reference 195 indicate similarparts tl'iroughc the severat views. I

The bell, which in this instance has the popular flower contour, illustrated as It will be'understood that if the bell is not 55 .in a non-collapsible horn being preferable to "6Q made up of ten tapering flexiblesheet metal numberedv from 1 to 10 inclusive. These sections are each permanently hinged to both adjoining sections, as at 11., said hinges 11 being on the inside ofthe horn and connecting said curved side edges. Along each of said. side edges are originally stamped in each plate a succession of tongues 12, which are then bent, curled or rolled to form eyes 13, the eyes along one curved edge alternating with those along the contiguous curved edge and fitting therebetween, so that th: eyes are all coincident or co-axial, as seen at 11, Fig. 1. Connection is then ejfected by means of a wire 14, thus joining each couple ofsections together by meansof a continuous hinge. By making each eye wholly on one side of the section, as seen bestat Figs. 4 and 5, tight joints ai e 'produced, so that little, if any, light can be seen through the hinges, thus conduing to the excellence of the acoustic properties of the horn. It will be understood that the wires 14., considered either alone or in connection with the eyes 13, constitute stiffening ribs at the joints of the bell. This, furthermore, is a very substantial and durable method ofconnecting the sections and forming the bell, and may be resorted to even in cases where it is not desired to produce a foldable bell; and in such a case, the joints may be additionally stitfened by the hse of a little solder, if desired, and the eyes may be on the outside instead of on the inside of the bell; and each of the sections may be in the form of a single or integral plate, as

seen at Fig. 7.

One method of forming a collapsible horn consists in dividing each of the said sections into two strips, which are'hinged together in ,the manner already described. A pair of such strips marked A and B is seen at Fig. 10. A blank for making such strips is seen at Fig. 6; tongues 15 being formed on the righthand side edge at said figure, which tongues are bent to form eyes 16. These eyes are connected by a wire 14, thereby forming a hinge similar to the hinge 11, with the exception that this hinge, marked 17, is straight as at Fig. 10, when the bellis folded, and that the hinge is on the outside of the bell, Fig. 1. Each of the strips A, B, therefore, has one straight side edge, along which edge the strips are joined to form a pair, such pair corresponding in dimensions to one of the sections above mentioned. The puter side edge ofeach strip diverges from the inner side edge from the .neck to the mouth of the bell, Fig. 10.

The'horn may be folded in the form seen in full lines at Fig. 12, by simply turning the strips upon the hinges alternately in and out in the manner of the plaits of a common fan, eight of the sections, or sixteen of said strips being treated in this manner, whereby two sets of strips or plaits. marked respectively and D, are folded and packed facewise together, one set opposite the other set.- Preferably, sections 1 and 6 are unthe sets of plaits C and D. This packa e,.'

at Fig. 12 it will be seen,'has minimum imensions, being of a length equal to the length of the bell, and of a width equal to the width of one section, and of athickness equal to the thickness of ten sections, so that it can be packed conveniently with a phono 5 graph for shipment, and can be conveniently transported or stored by the user.

- In openin the bell, from the Fig. 12 position to the Fig. 11 position, when the same is nearly open, each pair of strips is sprung outwardly from the Fig. 3 to the Fig. 2 pos1- tion, near its outer edge, this characteristic of springing or buckling being due to the curvature of the'outer side edge of eachstrip, where one section joins the next; and it contributes to the stiffness of the bell. It will be understood that the hinge wires 14 in the joints 1? are straight in the Fig. 12 position, but are flexed outwardly when the bell is opened; and it will also be under-' stood that the strips A and B should be rela-. tively narrow and long, as the use of a relatively large number in buildin up the bell renders it more convenient to old and open the same. 1

It will be perceived that all of the strips are permanently connected, so that the structure is continuous, and for ordinary purposes inseparable at any point, whether open as at Figs. 1 and 11, or closed as at Fig. 12, so that in o iening or closing, it is only necessary to uniold or fold as the case may be, without the necessityof manually oiningpr disjoining any of the sections. This form of joint between the sect-ions is valuable, because undue springing or tensioning of the metal in formlng seams, as heretofore generally practiced, is avoided, and hence the bell delivers the sounds more clearly than in prior horns of this type. At its outer end,

each of the strips or sections is rolled over a wire 18 as seen at 19, Fig. 3, thus to stifien the bell and protect said edge from injury.

In assembling the horn, after the bell is opened, I preferably insert a funnel or tapering tube 20, whose large end fits closely within the tapering neck of the bell. Over this funnel, I which fits over said bell neck; and a nut 22 is turnedupon a threaded projecting portion 23 of the inner funnel, and bears up place a second funnel 21,

' force the same .up over the-bell neck, and

siimiltaneously draw the funnel 20 outwardly within said neck. The funnel 21 tends to wedge the neck inwardly while the .funnel 20 tends to wedge the neck outwardly,

and as a result the neck is firmly clamped between said funnels, thus producing a rigid and substantial. phonograph horn. Anair pace 25 is formed between said funnels, and tends to avoid faulty acoustic action. A nipple 26 is formed on the inner funnel beyond the threaded part 23. V

At Fig. 8 is shown aform of tunnel or tip for a bell adapted toanother style of phono graph from the Fig. 1 construction. In this case, the tip 26* is tapering, and the funnel is relatively short, while the outer funnel 21 is so short as .to be little more than a ferrule to bind the neck of the horn against the innerwfunnel; this being accomplished by a nut Qfijofrelatively large diameter. j

Variations may be resorted to withinthe scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I claim: 5 l
