my invention, While its scope Will be as readilyundersto'o-d trom the appended claims. In the d-ravvings, Fig. I is'a plan view of a candy spinning machine conveniently enibodyi ngz-i-ny invention. Fig. II is .a vertical sectional elevation the seine. I

heatinguneans and the driving motor {and detail view showing the heating element and the manner of i Fig. 1V is a disposal oi the heating units therein. is 1 a ts herein 'shov' 11, a' candy fin-aohine characteristic "of my invention consists pess'elr tiall'y ofa spinning elenient with associated heating means comprehensively designated at 1', an encompassing receiver 2 for 001- lecting the fibrous strands continuously discharged frointhe spinning element, a driving motor 3', and .a'casing or base i upon which these'var-ious parts are mounted for The spinning element 1, it Willbe noted, is in the forn of an "open topped receptacle 5;With a body portion 6 of frusiro-m a comparatively broad; shallow, circumterenti'ally flanking portion 7. This shallow base portion 7 is in direct communication with the body por- 'tion'fi and is purposely instituted to pronlote spreading "of the sugar in an extensive"- layer over the heated bottom of the receptael'e 5, and its passage as -a rather fine film, to the radially disposed jet outlets 8 in a vertical peripheral flange indicated at 9.

vbotton'i consists of two sepaiable-rnetallic plates 10 and 11', the latter of Whi h, as'best hoWn in Fig. IV is spirally groovedso that'electric heating coils 12 and 1'3 of corresponding configuration may be accommodated substantially in the plane of juncture or abutment of the plates; The bottom of the'receptacle thus serves as a 'uefi'ed through contact, enroute to the jet :outlets, and in Whichthe coils are completely "embedded for'protection and as a precau- "tion against tire hazard. Assemblage ofthe o f niovabie parts li-k ely "to tease to eeservers when thejmacomponent :parts of the receptacle structure 'i'sm'aintained through the rnediuin of-cap screws I4: which pass through the flanking port-ion 7 and take hold in'the pl-ate IO. Elie heating hnits or coils '12, 13 are {prefen ablyo-f the type in which fthe'resistance ire is Wholly. surrounded byji nsulati'on encased of v heating element whereby the sugar is 'l'iqin a metallic sheathing, and it is to be especially noted that the convolutions of the spirals are respectively mutually interspersed or nested and in close proximity for greater compactness and heat concentration. The nesting of the coils, as will be apparent from Fig. IV, in turn promotes uniform heat distribution even though the coils are used separately as will be hereinafter explained in detail.

The receiver 2, as best shown in Fig. II is generally bowl shaped with an annular troughed channel 15 surrounding a central opening 16 through which the receptacle 1 protrudes. The top edge of the inner wall of the channel of the receiver is overhung by a marginal extension 17 of the bottom plate 10 of the receptacle so as to preclude the possibility of entry of the sugar floss into the opening 16. In order that it may be readily removed for cleaning, the receiver 2 is not secured to the base but merely rests upon a number of radially disposed cleats 18 which are concaved in conformity with the cross section of the channel 15 and therefore function to hold said receiver against displacement relative to the spinning element 1.

The spinning element aforesaid, see Fig. [I, is mounted upon a spindle 20 to which it is secured, a set screw 21 being provided in the depending hub of the bottom plate 11, assistance being also lent by a nut 22 threaded upon the reduced upper end of the spindle and bearing directly upon the companion bottom plate 10. Also secured to the spindle is a disk 23 disposed in spaced relation to the receptacle bottom by virtue of the abutment of its hub against that of the bottom plate 11. To the bottom of the disk 23, are attached, with interposition of a disk of insulation 24, a number of contact rings, in the instance shown, three in number indicated respectively by the characters 25, 26 and 27. To the inner ring 27 are connected, through the medium of leads 28, 29, the inner terminals 30 and 31 of the heating coils 12 and 13 respectively, while the outer terminal 32 of the coil 12 is similarly connected to the ring 25 and the outer terminal 33 of the coil 13 to the ring 26. Ourrent is conducted to the contact rings 25, 26, 27 by brushes 34, 35, 36 respectively, said brushes being guided in suitable holders 37, mounted in the top of the base and urged against the rings by helical compressure springs 38 concealed in the bottoms of the holders. The spindle 20 is rotatively supported by a bearing 39 mounted in or forming a part of a plate 40 secured upon the top of the base 4 and covering an opening 41 therein. Said spindle 20 furthermore extends tot-he interior of the base and receives additional support in an anti-friction thrust bearing 42. A grooved pulley 43 secured upon the portion of the spindle within the base 4 intermediate the bearings 39 and 42 receives motion by virtue of a belt connection 44. with the driving motor 3, which, as previously stated, is mounted upon the top of the base 4 adjacent the receiver 2 and over an opening through which its shaft extends.

In order that differ ,n't degrees of heat may be selectively maintained during the spinning operation, I have. instituted the provisions about to be described. To this end, the coils employed are of different capacities and subject to the control of a switch 45 of aconventional type, shown in elevation in Fig. I and diagrammatically in Fig. III, and capable, through successive shiftings of its operating knob 46, of connecting the coils individually or collectively with the source of electrical energy, the power leads-of the circuit, in the latter of the two figures referred to, being indicated by the numerals 47 and 48. The leads 47, 48 are connected through interposed fuses 49 and conductors 5051 with the switch terminals 52-53. The latter 53 of these terminals together with the remaining terminals 54, 55 are in turn respectively connected by conductors 56, 57 and 58 with the brushes 35, 36 and 34 hereinbefore described as contacting with the rings 26, 27 and 2:") with which the terminals of the heating coils 12 and 13 are in circuit. In this connection, a pilot lamp 59 may be employed as an indicator of current flow, said lamp being supplied by conductors 60, 61 lead ing from the contacts 5354 of the control switch 45. Current for the motor 3 is conducted from the line leads 47, 48 through fuses 62 and conductors 63, 64 a control switch being interposed at 65, see Figs. I and III.

In operation, the switch 45 is first thrown to connect both coils 12, 13 for quick heat ing, the motor then started to effect rotation of the spinning element 1, and the sugar (preferably of the granulated variety) is poured into the opening of the receptacle 5. liquefied through heating, and, discharged as floss into the receiving bowl from which the finished product may be-readil removed manually or otherwise as it eumulatesi After the receptacle bottom has become thoroughly heated, one or the other of the heating coils 1213 may be cut out by proper manipulation of the control switch 45 as may be found necessary or'de sirable in continued operation for proper production of the candy floss, thereby permitting practice of economy in current con sumptio-n. It is of course obvious that in lieu of two coils as many more may be employed as required in machines of difl'erent types or capacities. The embedding of the heating Coils o andv consequent of avoidance of direct contact with the mat-erial being fused, prevents scorching or burning, thereby enhancing uniformity of the product, and, what is of equal importance, entirely eliminating the fire hazard. Enclosing of the driving connections Within the base 4: not only serves to protect them but prevents possible injury to observers When the machine is used for display or advertising purposes.
