DRIER FORBAKERY OR SIJIVHLAR ICED GOODS.

SPECIFICATION formingpart of Letters Patent No. 714,420, dated November 25,` 1902.

Application iiled July 5,1902. Serial No. 114,466. (No model.)

T all whom it may concern:

Be it known that I, FREDERICK L. WETZEL, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented 5 certain new and useful Improvements in Driers for Bakery or Similar Iced Goods, of which the following is a specification.

My invention relates to dryingdevices, and has reference more particularly to frames on Io which iced bakery goods and similar articles are supported for a period of time sufficient to effect the thorough drying of the icing or other coating previously applied thereto. In the manufacture of many kinds of bakery I products the individual cakes are dipped in a viscous or semiliquid coating, after which it is necessary to support the cakes separately and out of contact with each other until the coating has become thoroughly dry in order to zo prevent the cakes from sticking together.

Various kinds of devices for this purpose have been used; but my present invention relates to improvements in that class of dryingframes wherein the cakes are individually i 125 I impaled upon supporting-rods provided with `3o individual cakes isolated or separated from.

each other. A

p The principal object of my invention is to provideadrying-frame of the character speciiied wherein the removable rods supporting `3 5 the cakes shall be securely held against displacement in any direction, as well as against rotation `on their own longitudinal axes, during the operation of stripping the dried cakes` from their impaling-prongs, at the same time,

4o permitting the series of supporting-rods to be unlocked and simultaneously removed from` the frame by a single upward stripping Inoveside member being hereinafter designated by ment of 'the operator.

Another leading object of my invention is i to provide adrying-frame of the class referred to possessing a greater capacity than frames hitherto known and used.

Other minor objects of my invention will appear later in the following description. Y

To these ends my invention consists in an improved drying-frame for the class of goods referred to possessing the peculiar features of construction and operation, all substantially as hereinafter described and claimed.

My invention in a preferred form is illustrated in the accompanying drawings, where- III- Figure l is a front elevational view of my improved drying-frame, showing a sufficient number of the cake-supporting rods in place 6o thereon to illustrate the manner of supporting and locking said rods and also the offset relation of said rods to each other. Fig. 2is a top plan view of the same, the supporting rods and cakes carried thereby being removed; and Fig. 3 is a detail vertical sectional view through a portion of the frame and the supporting-rods, further illustrating the manner in which said rods are locked against vertical displacement in the frame.

In the drawings, 4 designates the horizontal sill or base member, 5 and 6 the parallel uprigh-ts or side members, and 7 the top transverse member, of a rectangular structure constituting the supporting-frame, to which are applied the cake supporting rods hereinafter described. The lower ends of the side members 5 and 6are provided with short legs 8 and 9, respectively, extending below the sill 4, which legs are designed to coperate with 8o vertical side grooves formed in the outer faces of the horizontal sill members of a novel suplporting-truck, which constitutes the subjectmatter of an application by me led concurrently herewith, Serial-No. 114,463. In the faces of the vertical side members of the framework are anumber of pins, the outer ends of which, as shown in Fig. 2, are outwardly bent to lie parallel with the face of the frame. These pins are arranged in two vertical and 9o relatively odset series, the outer series of one side member and the inner series of the other the numeral 10 and their outwardly bent ends by the numeral 10, while the alternate 95 inner and outer vertical rows of pins are correspondingly indicated by 11, with their out# wardly-bent ends identified by the numeral 11a. These pins 10 and 11 are designed to aiford supports for a number of transverselyroo extending rods provided with prongs on which the cakes are impaled for drying purposes. These rods in constructional respects are all alike, but are composed of two offset or staggered series, (designated by 12 and 13, respectively.) The rods 12, which engage and rest upon the two left-hand rows of pins 10, are provided with downwardly-bent ends 12, which lie fiat against the vertical faces of the side members of the frame, and being embraced by the Voutwardly-extending ends 10 of the pins are securely held against movement either away from the frame or rotation upon their own axes. The rods 13 are correspondingly provided with down wardly-bent ends 13a, which perform the offices already described for the rods 12. The rods 12 and 13 are further provided with a series of upwardly-inclined prongs or tines 12b and 13b, respectively, upon which the iced cakes 14. are impaled. These cakes are of various sizes and shapes, but are for the most part of circular form, and it will be observed that by laterally offsetting the rod-supporting pins in the manner shown the two series of rods 12 and 13 are enabled to be placed much closer together than would otherwise be the case, owing to the fact that each cake on any one of the rods occupies to some extent the space lying between the two adjacent cakes on lthe next rod thereabove. This manner of supporting the rods therefore effects a material economy in the space required for drying purposes, (which, of course, is limited by the dimensions of the frame,) and thus materially increases the capacity of each frame over a construction wherein the rods are supported on a single Vertical series of pins arranged in single rows on each side member of the frame.

I will now describe the improved means I have invented for simultaneously locking and unlocking all of the rods 12 and 13 upon the frame.

15 and 16 designate a pair of bars disposed parallel with the side members 5 and 6 ofthe frame and hinged. to the latter at the rear inner corners thereof in the manner plainly illustrated in Fig. 2, wherein these bars are represented as swung rearwardly in an unlocking position and lying back to back with their respective supports. From the faces of these bars project pins 17 and 18, respectively, the pins on each bar being arranged, preferably, in a single vertical row,there being one pin for each of the rod-supporting pins 10 and 1l of the adjacent frame members, each pin being disposed in a horizontal plane, which is higher than the horizontal plane of its appropriate rod-supporting pin by the thickness of the rod itself. From this construction it will be readily seen that when the bars 15 and 16 are swung forwardly into locking position, as shown in Fig. 1, the pins 17 and 18 will all simultaneously ride over their respective rods 12 and 13, securely locking the latter against Vertical displacement.

This is a great advantage, in that it enables the operator to use both hands in stripping the cakes from the prongs, the rod remaining on the frame, while heretofore it has been necessary for the operator to remove the rod from the frame, and then holding the rod with one hand strip it with the other.

The manner of using my improved dryingframe will be readily apparent from the foregoing description. The rods having the freshly-iced cakes impaled thereon are readily placed upon the frame one after another, during which operation the locking- bars 15 and 16 are swung backwardly, as shown in Fig. 2. As soon as the frame is loaded the locking-bars are swung forward to the locking position shown in Fig. 1, whereupon the frame may be allowed to stand a sufficient length of time until the coating of the cakes is thoroughly dry. As soon as the cakes are ready to be removed this may be done in the manner already described, whereupon the operator simply turns back the locking- bars 17 and 18, and then placing both hands beneath the lowest rod 12 or 13 removes all the rods substantially simultaneously by a single upward movement of the hands,whereupon the rods may be washed, :ready for reuse in the manner already described.

It will be noticed that the above-described construction serves to hold the rods absolutely rigid while the locking-bars are in operative engagement therewith. The downwardly-turned ends of the rods render longitudinal displacement of the latter impossible, and also in coperation with the outwardlybent ends of the supporting-pins prevent outward movement or rotative movement of the rods, while the pins of the locking-bars prevent vertical movement. At the same time by the mere swinging back of the lockingbars the entire series of rods may be quickly stripped from the frame by a. single move ment of the operator.

It is evident that various modications and changes might suggest themselves to the skilled mechanic in connection with my invention, and hence I do not limit the same to the precise details and relative arrangement of the parts shown and described except to the extent indicated in certain of the claims.

I claim- 1. In a drier of the character described, the combination with a supporting-frame, of parallel cake-supporting rods removably mounted on opposite side members of the frame, said rods being provided with impalingprongs so positioned that the prongs on any two adjacent rods are offset or staggered relatively to each other, substantially as described.
