TOY BELLOWS AND REED Filed March 24, 1926 Patented July 1, 1930 ATES ERNEST IBOGCHINO, or NEWARK, NEW Jims im TOY BELLOWSAND REED Application filed March 24,1926. seiia1 No. 97.139.

This invention relates to bellows, more particularly to small types used in connection with wind operated reeds in theproduction of sound.

One object of the invention is to provide a strong and efficient bellows operated by direct compression and composed of few and simple parts.

Another aim is in the provision of a cylindrical type of bellows designed to be easily and rapidly assembled and which protects the ends of the spring from causing damage embodiment of the invention.

.Figure 12 is a transverse sectional view taken on line 12- -12 of Fig. 11.

Throughout the several views the numeral 15 designates in general one of the heads of in operative the bellows,'all of which are shownas' cylin: drical, and 16 the opposite matinghead; In Figs. 1 and 2 the heads have integrally formed with them bands or rings 17 and 18 over which is a fiexible'fabric strip secured by an adhesive to form anjimpervlous cylindrical casing 19, the preferred material being ordinary commercial adhesive tape impregnated or covered" with a stick'y'pitch or wax-like preparationthat retains the fabric position on the 'rings,is sulficiently flexible and air tight to produce the desired results. p l Formed in the'heads 15 and1 6 are openings 20 arranged in anypreferred' manner and of such size and number 'as maybe rep quired, by which thedevice may be -fastened to be used.

to objects with which it is Setin one of the heads, as;"15',;'is1ai reed 21 openatoneend to the'atmosphereand at the other to iscusto mary v I v A coarsely wound spiral compression the'interior of; the bellows as spring 22 is disposed within the casingpits ends abutting the respective heads andx'are protected from puncturing or otherwise injuring the fabric wall by reason oft'heyguid ing rings 17 and 18. :In the type'shown in F igs.-3 and ithe heads are made separately from'th'e rings which are however firmly secured together, the difference being one ofconstruction only. In Figs. 5 and 6, thehead 15fis held with in and at about the center of length of a cylindrical band 24 which. thus extends at both ends beyond the head, protectingthe reed from damage bycoming in contact with objects which might tend to displace or injure'it, the lower head being iofthe' constructionsho'wn in Figs. 1 and 2.; l

Figs. 7 and 8 show merely thatithe upper head 15 is held in a reversed position relative I In this case the flexible fabric casing eleif.

ment 27 is secured only adjacent its marginal edges, as at 28 and 29 to the respective cylinders 25 and 26 near their heads.

Thus the casing controls the opening or distance between the heads and also prevents the leakage of air from the cylinders, which obviously are loosely fitted.

The heads, rings and cylinders may be made of suitable thick paper or of metal as may be desired, the main novelty residing in the manner of applying the flexible casing, which, as indicated, is taken from a strip of suitable material and cut of such length as to overlap at'its ends. r

In the construction of reeds of the types used in connection with bellows, it is customary to wrap the reed body 21 and vibratable tongue 30 with a fine thread and thereafter wind a strip of paper or the like over the threads before inserting in the opening in the head, at which time, in order to prevent leakageof air and consequent failure of the reed to operate, it is necessary to use melted paraffine or the like to provide an air tight structure.

-Infthe present case the body and tongue are wrapped with a strip of adhesive tape 31 of the nature described, forming a close fitting joint impervious to air and requiring no securing means, the use of such tape constituting a material improvement.

While certain preferred embodiments of this device have been shown and described, it will be understood that changes inthe form, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as neW and desire to secure by Letters Patent, is V 1. A toy bellows comprising a pair of rigid circular heads having flanged rings at their edges, a helical spring pressing said heads apart, said spring being held in operative position by said rings, and a strip of adhesive tape applied in the manner of a band to said rings.

2. A toy bellows comprising a pair of rigid circular heads having flanged rings at their edges, one of said heads having a reed inserted therethrough, said reed being Wound with an adhesive tape to form "an air tight joint, an expansion spring loosely confined. by said rings. to press said heads apart, and a casing composed ofa strip of flexible impervious material secured, by a viscid adhesive on the outer surfaces of said rings. 7
