My invention relates to reference systems for materials required in the production of commodities, and more particularly to ingredients for baking doughs, and my main object is to provide a system which simplifies and expedites the task of procuring the proper materials for the particular need.
A further object of the invention is to provide a reference system which enables the required materials to be determined by accurate means and without difficulty.
Another object of the invention is to provide a reference system which combines versatility and order of importance in respect to the items filed therein.

In the baking industry, various formulas are employed for reference when preparing sponge doughs, straight doughs or other mixtures. One system of reference may employ a large frame or cabinet bearing the entire array of formulas without distinction as to importance or frequency of use. It is apparent that a reference system of this type creates frequentopportunitiesfor confusion and error in such items as ingredients and their weights, resulting in spoiled mixes and non-uniform or unsalable products. Another method of filing formulas is by impaling them on the desk spindle or hook, or tying them together with a string and suspending them from a hook. Obviously, much time may be lost in an attempt to find the proper formula in this type of receptacle, not to speak of chances to make errors and the inevitable soiling or tearing of the sheets so that they are unfit for use. A still further method involves daily repetition in copying identical kinds and amounts of ingredients for individual doughs and is costly because much time is devoted not only to necessary reference items but to many which are infrequently needed, not to speak of confusion and probability of errors incident to work of this kind. It has therefore been my intention to eliminate the above difficulties by the provision of a system which minimizes complications, hazards and efforts incident to filing and selection of formulas in the baking industry or in fields dealing with corresponding conditions.
In contemplating a unit for a formula file, a cylinder or roll bearing the formula in relation to a master card appears to be the most eflicient expedient. Thus, with values stepped off along the periphery of the cylinder, the rotary adjustment of the latter in relation to the master card will present the successive values in positions adjacent to the card and so facilitate the reading or selection of such values.
In accordance with the expedient just outlined, specific reference to the drawings indicates an apparatus equipped with a set of the roll units mentioned. Thus, a rectangular housing or cabinet is illustrated in Figure 1, such cabinet having suitable means ID to suspend it on a wall, and being formed with a top H, a bottom l2, a medial shelf I3, ends l4, and a door l5 hinged to the cabinet at one side, as indicated at l5e. The door and I9.
As seen in Figures 1 and 2, the space between the door l5 and the partition 16 is largely occupied'by upper and lower sets of the vertical cylinders or rolls 20 around which are wrapped the formula sheets 2 I.
One of these is shown-in the center part of Figure 3in the fiat form preliminary to being wrapped, and it is seen that the sheet is made with inward terminal bends 2Ia which tuck into a longitudinal slot 26a cut in the periphery of the roll when the sheet is wrapped, as clearly indicated in the right hand portion of Figure 3. In order to retain the sheet in the wrapped form, I employ a wavy strip 22 of spring steel, the strip having a horizontal top bend 22a. 'Ihe'strip is inserted edgewise into the space between the sheet bends ZIa, as suggested by the arrow in Figure 3, so that the stripappears lodged as in the upper center of Figure.
1, with its top bend 22a overlying the top of the roll sidewise of the groove 20a. On account of its wavy form, the strip 22 is put under tension when lodged between the bends Zla, and therefore bears against the latter to retain them in place.
In order that the set of rolls be properly mounted in the cabinet, the shelf I3 is made with apertures I3a at selected points to receive'center pins 2327 depending from the lower ends of the rolls and indicated by dotted lines in the center of Fig. 4. The upper end of each roll is formed with a pair of diametrically spaced cavities 200 intowhich depend pins 231 carried by a horizontal disk 23 located over the roll, such disk having an upstanding rim 23b somewhat less in diameter than the disk itself. Also, the latter has an upstanding spindle 24 passing freely through an opening in the top II of the cabinet to receive a finger knob 25 secured by a set screw 2511.. About the spindle 24, the cabinet top I I is slightly sunken in its bottom surface with a circular recess I Ia, this recess and the interior of the rim 23b forming seats for the ends of a compression coil spring 25 surrounding the spindle 24. As the assembly appears in Figures 1 and 4, the expansive tendency of the spring 26 maintains the disk 23 in locked relation with the roll by the agency of the pins 23a, so that the roll may be rotated when the knob 25 is manipulated. Should it be necessary, however, to change the roll for one bearing a different formula, it is only necessary to raise the knob 25 whereby to release the roll from the locking pins 23a, in which event the roll may be slightly raised and removed from the cabinet. The action just described is suggested in the illustration of the second upper roll from, the right in Figure 1. To facilitate the removal of the rolls, the front edge of the shelf I3 is concavely recessed at I3b under each roll for a better reach to raise and remove the same. The arrangement in reference to the lower set of rolls is precisely the same as just described, but in inverted relation, the depth of the apertures I; being ample for the dual function, as suggested in Figure 4.
The frontal columns of the formula rolls are rendered visible from the front when the cabinet is closed by the provision of slots I5a at corresponding places in the door I5. Thus, by means of these slots the roll columns of figures or other legends may be brought into View by simply turning the selected knob 25.
The master cards with which the formula roll columns are intended to be read are grouped in an array upon the door I5. As more clearly shown in the left hand portion of Figure 3, the card 2'! is a long vertical strip of pasteboard or other firm material and is encased in a retainer plate 28 having inturned side and bottom flanges 23a. The card is inserted by being slid down into the retainer to the position shown, which leaves a small portion of the card projecting. above the retainer. Thus, it is easy to remove the card and replace it by a different one when the data carried by the retainer is to be changed. One side channel of the retainer receives a wire rod 29 whose upper and lower ends are bent horizontally and sprung into small perforations 29o made in the door I5 at points laterally of the slots I511. The rods 29 thus become pintles on which the card bearing retainers 28 are hinged. Various positions in the hinge action of these are illustrated in the upper portion of Figure 1. Thus, the retainer is shown flat against the door I5 at the extreme left, fully exposing the slot I5a. The next showing toward the right represents the retainer as partly swung out; the third showing indicates the retainer fully swung out; and the right hand showing indicates the same closed upon the slot I50. While the master card is fully exposed to view in the first position mentioned, only its upper projected portion is visible when the retainer is closed. Also, the rollers are located closer to the front for visibility, by recessing the door at I51 when the latter is of thick material, such as wood.
Figure 5 shows a modification of the rolls 20 where it is advisable to use a taller formula sheet. In such event, the cabinet may be laterally spaced off with partitions 3H and a full-height roll 26d disposed in one or more of the compartments so formed. As noted, the bearing and manipulating construction incident to this roll is identical with that employed in the previous instance, except that the top I I of the cabinet is used as a bearing and not for manipulating means.
Figures 6 and 6a show a modification of the tension means for holding the rolls in place. The spring 26 is now replaced by a forked block 3| which straddles the spindle 2 and serves as a spacer between the disk 23 and the cabinet top II. The block is of the proper thickness to be inserted between the spaced parts with a slight amount of friction, so that it permits the roll to be rotated while holding it in place; and the outer portion of the block is extended with a lug 3Ia to serve as a handle.
Figures 7 and 7a show a further modification of the roll retaining means. Here it is seen that the disk 23 is dispensed with, and that the medial shelf I3 of the cabinet is replaced by spaced individual shelves I30 between the cabinet and walls and intermediate partitions 30. Each upper roll carries a spindle 32 which is reduced with neck portions 32a opposite the shelf I30 and cabinet top II, these parts having slots I 311 and Nb, respectively to receive the reduced portions of the spindle when the roll is moved in the direction of the arrow in Figure 7a. The upper portion of the spindle receives a large washer 33 before it enters the knob 25. This form of control is simple, and the large size of the washer 33 checks the roll from tendencies to depart from its vertical position. The same illustration shows a bottom roll and a full-height roll installed in like manner.
It will be apparent from the above description that a variety of formulas may be compactly housed in the cabinet, yet so easily located and controllable as to expose any column in a selected formula to view. Such formulas as require frequent attention will make it necessary to keep their master card retainers 28 open, in order that the data on the exposed roll column may be readily correlated with that on the master card. As to formulas seldom consulted, the corresponding master card retainers may be kept closed, so
" as to fully conceal affected rolls and divert the attention of the observer therefrom. In this respect, an illustration may be made. Thus, the master card in Figure 3 shows the ingredients required for the preparation of a rye bread dough, the title Rye being marked above on the front and reverse sides of the top projected portion of the master card. The chart borne by the corresponding formula roll indicates in vertical rows the various quantities of the ingredients required in accordance with the size of the dough parcel or batch called for. Thus, the dough sponge "age or time since fermented is the first requirement on the master card, and the particular roll is chosen which recites the "age of the sponge on hand. The next consideration is the size of the load or dough unit, and the roll is turned to 2 lbs, 1% lbs., or any desired size. The figures below now indicate the amounts of basic sponge, rye flour and other ingredients required for the particular unit size. If the sponge age is greater, a roll of the rye bread series having the corresponding heading is chosen. However, should any type of dough seldom be required, the closing of the master cards upon the affected rolls will still expose the name of the variety at the top, to be conveniently located when wanted. Further, as an additional expedient to distinguish the different formula rolls at sight, I prefer to tint the various formula sheets or series thereof in different hues or contrasts, such expedient saving time when the observer has memorized the colors of preferred or frequently consulted formual rolls or series and can readily recognize or distinguish them. The file drawers l8 are used for the storage of spare formulas, and a small compartment in one of the drawers may be used for extra master cards as shown.
