' .jin ncation filedDecember 11, 1920. Serial 134301117,

To aZLw/wm it may concern? I y Be known that I, ,ALONZO Lauren BAUsnAN, citizen of the United States, re siding at Springfield, ingthecounty of Hampden and State oi'qMzissachusettghave invented new and useful Improvements in Plaque, oards, of. which the following is a Specification. I

This inventionjrelates to improvements in plaqueboards and, whilethe invention is capable of general application; it finds one advantageous use in-connection with appara tus of the class, disclosecLinU. S. Letters Patent'iN'o 1,123,934. granted oni January 1915, to Schrafit, Blake and. Lorentzen,

; .In apparatu'sof this class, freshly coated candies are-carried byva seriesoi'conveyers I throughva relatively long circuitous pathto and along tables, at whichare located pack ers who-remove the candies from the con W a P em h pm nt 1, 9 1 in the travel of the candies, theyar'e cooled sufiiciently to harden their coatings and generally the conveyersare enclosed and a cooling medium circulated vwithin the enclosure to hasten theprocess.

i The 'freshlycoated candies delivered from the coating machine,- on plaques, such as waxed papers or the like, and; these plaques are transferred from the delivery apron of the coating machine to plaque boards. The plaque boards; arethen slid into thecooling apparatus and carried ther'ethrough by. the various conveyers. Heretoforqthese plaque boards have, generally been constructed of wood and it has been necessary to construct them relatively thick to securethe necessary strength.- The fact that the boards are thick and constructed of material which .is a poor conductor of heat makes itsrnore diflicultto cool the candies. p I i This invention is concerned withthe provision of a plaque board which is constructed of metal and can accordingly be.n 1ade very much thinner than the wooden boardswith; out sacrifice to its strength. The' substantial reduction in thickness together Withthe choice of a material, which is a very good conductor of heat, permitsvery much more ra id cooling of the candies I v he object of they invention is to provide a i prev pe, QfP QQQbi d, whi h are usually per surface of is o s ehi ien that i al fbn a re relatively 'thln metal and yet be sumapl m i all respects "foruse in apparatus off heigen 5;-

s5 though not'necessarily; "of; generally rectangula'r, form, as shown; The main' body ..of

theplaque board is merely a,,fl at, ,thin, sheet 5. of suitable shape'and area, upontheiup.

w h th P ques, b ari -{t candies are placed. i

upon conveyers which carry 1 them; in verti In ,practice,tl 1eseplaqueboards are The vertical conveyers usually consistjof carries a series of angle irons a and eachXlOOT angle iron won one chain liesiopposite ya corresponding "angle on, the 1 other; chain.

Th P q oa d s mo ed d s f 't e the two sets of chains and is, supported along one edge anangle iron aof "one chain and along the oppos te edge by an fanglearon vertical conveyer. A complete disclosure of the conv'eyers and the cooling apparatus may be had by-reference to the above-mentioned patent.

111 order to provide a substantial surface, other than the thin edge of the sheet 5, for engagement with the lugs Z, end flanges '6 are provided at opposite ends of the board by upturning the ends of sheet 5 into substantially right angularrelationtherewith. These flanges, while verydesirable for the described purpose, are also advantageous in that they stiffen the-plaque board transversely, allowing it to be made of thinner metal than would otherwise 'be feasible, for the plaque board in practicesupports a comparatively heavy load of candies and the sheet 5-n1ight bend unduly without the flanges 6. Preferably, the flange is made ofdouble thickness as shown in, Fig. 3, byfirst doubling thepo'rtion 7 (Fig."5=)' upon the portion 6.

In order to pr'ovide'for the sliding of the plaque boards into andxout of the vertical conveyer-s of the cooling'apparatus, runners are formed along the opposlte side edges of the board. 'These runners are preferably formed integrally with sheet 5 by bending the portions 8, 9 and 10 of the blank shown in Fig. 5, along the dotted lines. The portion 8 isjturned downwardly at. right angles to the body 5, then the portion 9 is bent inwardly at right angles to portion 8, and finally the portion 10 is bent upwardly at right angles to portion 9, meeting, or substantially meeting, the undersurface' of the body 5. These'runners, aside from their function'as such, also serve very effectually to stiffen the plaque board against longitudinal bending under the load to which they are in practice subjected. The runners also may coact with the runways 1*, to guide the plaque boards and prevent their displacement during tliBlPhlO-"QHlQllt by the horizontal convevers.

- lnstead of making the plaque board eX- acting square at its corners, which would necessitate exact alignment of the board with the angle irons a in order to 1I1su're theirentrance, these corners are preferably somewhat-curved or inclined as shown at 11. To'permit of this-construction, the runners. described; do not extend quite the entire length of the body 5, but terminate a short distance from each end thereof.- ln addition, the blank shown in Fig. 5 is formed with a curved or inclined portion-12 which is bent downwardly at right angles to body 5 along the curved line which results in the curved ends 11. The lower-edge 13.0f the portion 12 forms a cam, so that, even if the angles a do not exactly align vertically with the runners of the plaque board, the boa-rd may nevertheless be moved into the vertical conveyers because it will be lifted by the cam surfaces 13 engaging the ends of angles a on longitudinal movement of the plaque boards. The curved surfaces 11' likewise constitutecams to shift the boards laterally in a similar manner if notcorrectly alined horizontally with angles a.

When it is desirable to secure additional strength, a. reinforcement may be placed within the hollow runners, as i-ndicated'at 20 in Fig. 6.

I The plaque board vdescribed is important in that it is adapted for quantity production at relatively low cost. The boards are struck out readily from a single sheet of metal into a' blank, which may be shaped up into the form shown by simplebending operations.

Aside from this feature, the plaque board is light, and constructed with an economical use of material, which is intelligently dis tributed to afford the necessary strength for the'intended service." The use of thin Inaterial and material which is a'good conductor of heat is particularly desired in that it aids in'rapidly cooling the candies, particularly their bottom coatings. v

The invention has been disclosed herein,

in an embodiment at present preferred, for

illustrative purposes, but the scope of the invention is defined by the appended claims rather than by the foregoing dscriptiong \Vhat I claim is 1. A plaque board, comprising a relatively thin flat body portion of metal to support the candy laden plaques, having portions along two oppositeedges turned downwardly and then inwardly'therefrom to form runners, and a portion converging from eachend of each runner tothe under surface of said body portion. w

'2. A-plaque board, comprising, arelatively thin flat body portion of metal tosupport the candy laden plaques, and having at opposite corners convergent portions forming cams, runners provided on the under surface of the body portion and extendinv along the side edges thereof 'between sai convergent portions, a cam forming, convergent portion to connect the lowersurface of each end'of each runner to the underside of the body portion adjacent its ends, and a flange bent from each end of said body.

3. A'plaqueboard, consisting ofa metal sheet having portions along each side turned downwardly and then inwardly therefrom to form runners to facilitate sliding of the gagement by conveying means, together with portions adjacent each corner which are so bent with relation to the body of the board -to form cams for moving the board horizontally or vertically when conveyed into the desired position.

'4. A plaque board, consisting of a onepiece sheet of metal having a portion along each side edge bent downwardly, then inwardly, and then upwardly toward the body of the sheet to form runners upon which the tray may be readily slid, and flanges at each end formed by upturning the ends of the sheet, and inclined portions provided to connect the lower surface of each end of each runner to the lower surface of the'body of the sheet at the ends thereof.

5. A plaque board, comprising, a relatively thin fiat body portion of metal tosup- 1 port the candy laden plaques, and having at opposite corners convergent portions formingcams, runners provided on the under surface of the body portion and extending along the side edges thereof between said convergent portions, and a cam forming convergent portion to. connect the lower .surface of each end of each runner to the underside of the body'portion adjacent its ends.

In testimony whereof Ii have afiiire'd my signature.
