provide an improved, simple and `efficient ma- 7.

chine for glazing bakers products. l A second importantV object-of the invention is to provide a machine for the purpose whereby both the upper and the lower sides of an'article passing through the machine willbe effectively 2" glazed.

A third important object of the invention is .to provide a machine for` the purpose whereby the glazing of both sides of an `article passing through the machine willk be effected simultaneously.

A fourth important object of the invention is to providev a machine of this class wherein liquid sugar is kept in circulation during operation of the machine. l Y

A fth important object of the invention is to provide `a novel machine loffthis class whereinV the circulating system for the liquid sugar and the other parts contacted by liquid: sugar may be easily and effectively cleaned so as to prevent clogging by crystallization of the liquid-sugar when the machine is not in operation.

With the above and other objects in view, as will presently be apparent, the invention consists in general of certain novel arrangements of details and combinations ofparts hereinafter fully described, illustrated in the accompanying drawings and particularly claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a side elevation of a machine constructed in accordance with this invention.

Figure 2 is a fragmentary section on the line 2 2 of Figure 1.

Figure 3 is a fragmentary section on the line 3--3 of Figure 1.

Figure 4 is fragmentary section on the line 4 4 of Figure 2.

Figure 5 is bottom view of a portion of a spray pipe suitable for use in this invention.

Figure 6 is a section on the line 6 6 of Figure 5.

Figure 7 is a fragmentary elevation of portion of the invention, the view being taken from the side opposite Figure l and disclosing parts hidden in that ligure.

Figure -`isa"fragmentary section on the line 8 8 of Figure '7p` i f In theembodimentof` the invention as herein disclosed there is' provided a pair of side frames of suitable structural material. Each of these side frames Vconsists of a bottom member or sill l0 adapted to rest' on a floor or other support. Atthe ends of each sill are uprights ll which have their upperk ends connected by longitudinal members l2. -An intermediate upright member l3connects each sill Il! with the corresponding member l2 `offthe respective frame side. The two side frames are suitably connected at the supplyor input end of the device by a cross member I4 and-at the output end by a similar cross member I5.-

Supported/between the side frames is a tank open-at the topa`nd having sides AI 6. At the output endoffthe machinev the tank is shallower than atI the input end and has a bottom which inclines downwardly from the output end toward theinputendasat il. From the input end of this bottom-a vertical wall- I8 extends downwardly to the bottoni of A-theinput end of the tank. This end ofthetank-fthus Jforms a collecting pit or sump for holdingfa` supply of the liquid sugar coating material.

Extending downwardly the bottom IB of the sump islapipe 20"which' connects with a horizontalpipe-zZlj-leading vtothe intake side of a pump' 22." Extending from the outputside of this pump is a pipe having a horizontal portion 23 and a vertical portion 24. The vertical portion 24 is connected at its upper end to a spray pipe 25- extending horizontally across the machine from side to side thereof and supported in brackets 26. The pump 22 is driven by a motor 21 and this motor also drives a reduction gear 28 of any well known type. This reduction gear includes a sprocket 29. At the output end of the machine there is provided a shaft 30 which extends through the side walls of the tank and is journalled in bearings 3l carried by brackets 32 fixed to the outer faces of the tank side walls. On one end of the shaft 30 there is xed a sprocket 33 which is connected by a sprocket chain 34 with the sprocket 29. On the shaft 30 within the tank there is provided a pair of sprockets 35 each being positioned close to a respective side of said tank. The sprockets 35 are xed by set-screws 36 or other suitable means to the shaft 30.

At the input end of the machine the tank sides have oppositely disposed slots 31 extending horizontally and having their upper and lower edges sprockets 35 with the pair of sprockets 44, the

belt having adjacent its edges the usual holes' for receiving the sprocket teeth. It will nowy be plain that the crossheads and screws constitute belt tightener means. The belt 45 -lsfnea'rlas wide as the tank and the upperrunfofthis belt passes beneath the jet pipe 25`so that articles on the belt will receive the discharge fromj the jet holes 46. The belt 45 is made of any suitable porous material such` as woven fabric. Beneath that portion of the belt below the jet1pipe 25 the upper run passes ,over a plate 47 which is supported onfangle 'brackets 48 securedl to theinner faces ofthe tanksides. The purpose ofthe plate 4l is to prevent-passage of the` glazing liquid for a certain distance alonggtheupperrun of the belt. At the input-end of the belt-there is a feeder tray whereonthe doughnutsyor Aother articles to be `glazed are placed .for feeding onto the' belt 45. This tray is shown at 49. At the output end of-the machine thereis a rack 50 on which suitable trays or pans may b eplaced to-receive the glazed articles Afrom the belt.`

In order to be able to cl-ea-ngout .the pump and the pipes connected thereto whenthe machine is shut clown a shut off valve is .provided .in each pipe line close to the tankyand closeto the jet pipe, the latter being connected through a .union sothat the jet .pipe may bedisconnected for cleaning. In each pipe line there is -connecteda valve 52 for connection andlcontrol, Aof -suitable wash out and discharge hoseqor pipes.. Also cleanout doors 53 are provided ,inthe `side w-alls I6 for access to the interior ofthe tank and the lower run of the lbelt, for cleaning when de sired.

In the operationA of the invention rvavlgluantity of liquid sugar or other coating material is placed in the sump oi the tank, thefvalves 5|'.are opened and the motor 2l is started.. Theliquid sugar will be pumped from the sump and up to the jet pipe 25 to flow through the jet openings 46 onto the upper run of the belt which is, at the time, moving slowly from left to right of Figure 1. The doughnuts are fed from the tray 49 onto the belt and in passing beneath the jet pipe are sprayed with the glazing liquid. Since the pores of the belt are seal-ed beneath the jet pipe there will be an accumulation of glazing liquid above the plate r4l and the underV sides of the articles on vthe belt will be wet with the glazing liquid. After the upper run of the belt carries the doughnuts beyond the plate 41 the excess of the glazingmaterial will pass down through the pores of the belt into the tank and will there ow down the*4 bottom\ Il to the sump for recirculation. The doughnutswill be carried along and delivered at the output end onto trays supported on the rack 50.

What is claimed, is: In a-glazing machine for bakery products, an open top tank for containing glazing liquid, an endless woven fabric belt traversing the top of said tank, means for drawing liquid from said tank and delivering it onto successive lengths of said belt, said meansincluding a jet 'pipe extending vtransversely above said belt having a multiplicity of jet holes on its under side and a pumphaving pipe connections with saidV tank and withsaid jet pipe, said belt having upper and lower runs'.V and a plate beneath the upper run of said belt and` located beneath said` `iet pipe, the upper run of saidbelt moving over said plateresting on.` and in direct contact `therewith whereby the p'orosities of said'belt are `closed `in that portion of the belt in contact with 'said plate.
