This invention relates to a display device for readily and quickly exhibiting a particular group of data or indicia from a number of such groups and more particularly relates to a lubrication 5 and servicing data indicator in which groups of essential data and instructions are imprinted upon an endless web or belt which may be moved past a slot or window so that the particular group desired may be observed and correlated with supplementary data on the face of the device.
Heretofore, in accumulating and presenting data for the proper lubrication and servicing of a complicated mechanism, such as an automobile, such data have either been printed on large charts of the alignment type, or upon separate smaller cards or sheets which are bound into a book, strung upon wires or loops of cord, or otherwise assembled into one location for use. 20 The large charts are not convenient because of the difficulty in quickly picking out the desired data from the large number of groups of figures, names, instructions and the like, thereon. Furthermore when they are in the smaller book or loose-leaf form, so that the user must handle them, the single pages quickly become soiled and illegible from the grease and dirt that unavoidably accompany such servicing or lubricating operations. It is an object of this invention toprovide a means for conveniently and legibly displaying one particular group of data or indicia from a large number of the same, to correlate them with a supplementary group, and in such a manner that the whole will be protected from becoming soiled or defaced by the operator, by the operations performed or by the weather.
Another object is to provide a means of the type described which may be easily changed from one group or class of indicia to another, without handling or damaging the charts or surfaces carrying them.
Another object is to provide a display device in which the stationary chart as well as the movable element, each of which carries complementary parts of the data, are easily installed and removed for additions or alterations, and in which the said moving element is held in a secure and readable position with regard to the face of the device.
Another object is to provide a master chart or sheet bearing lubrication, identification, or servicing data on its face, and a relatively movable element bearing supplementary data, as for a given type or make of automobile, which latter element may be aligned or correlated with the master sheet in such a manner that the essential data desired, and none other, are readily observable.
These and other objects and advantages will be more fully apparent from the following description and from the accompanying drawings, which form a part of this specification and illustrate a preferred embodiment of this invention.
In the drawings:
Figure 1 is a front elevation view of a display device, showing the driving and idler roller and the web in place thereon, and illustrating the general type of indicia that may be placed on the cooperating parts.
Figure 2 is a vertical sectional view on line IIII of Figure 1.
Figure 3 is an end View of a preferred construction of a driving roller.
Figure 4 is a side view of a preferred construction of an idler and stretching roller.
Figure 5 is a view on line V-V of Figure l and shows a means for retaining the guide bar for the web. Y
Referring to the drawings and particularly to Figure 1, the numeral I represents a box or frame, which may be of light sheet metal, provided with brackets H for support on a wall or other flat surface. The front edge !2 of box It] is preferably flanged as shown in Figure 1, and also provided withmeans forming a groove or channel 13 (Figure 2) so that a flat sheet or card M can be inserted to form a removable front closure for the box as well as a chart for data.
Sheet 54 is imprinted with data or indicia forming a chart generally designated l and relating to the purpose for which the device is designed, for example, the exhibition of data on lubrication or servicing of automobiles. A particular provision of this invention is the means for correlating and aligning these data with corresponding data on a separate movable element, such as an endless belt, to be-described below, to give a predetermined relation as between the lubricating indicia, the locations in which particular lubricants are to be used; and the various makes, models and types of automotive equipment to which they may be applicable. In this example, to facilitate the function just outlined, there is provided a window or slot I6 extending transversely of sheet M, as shown in Figures 1 and 2. Slot It may be covered by a narrow transparent sheet ll of celluloid, glass, or the like, to prevent entrance of moisture or dirt, or the whole front of box In may be protected by a single large sheet of such material.
Immediately behind slot I6 is a guide or spacing bar I8, which is preferably hinged as at 9 to one side of box I, so that it may be swung out of the way when the web, to be described below, is to be removed or installed. The free end of bar I8 is preferably retained in clip on the opposite side of box II] when the bar is in its normal position (Figures 1 and 5). If desired, the hinge l9 could be replaced by a second clip similar to 20, without departing materially from the invention or the arrangement illustrated.
A driving roller generally designated 2| is mounted at the upper end of box l0 and serves to support and control the endless belt or web 22 on which certain of the indicia or data to be exhibited and aligned are imprinted. Roller 2| may conveniently be made of a wooden or fibre cylinder 23, fitted with a flange 24 at each end, to prevent the web 22 from becoming misaligned. A rod 25 is axially fixed to one end of the cylinder 23, extends outwardly through a suitable hole in the side of box l0, and is bent as at 26 to form a crank or handle. A simple knob or disc could be substituted for crank 26 if desired. Sleeve 21, which may be a short length of pipe, serves to space the cylinder 23 and crank 26 with regard to the side of box ID, as shown in Figure 3.
At the opposite end of cylinder 23 is an axial rod 28, slidably fitted in bore 29 and urged outwardly as by spring 30. The outer end of rod 28 passes through a suitable hole in the side of box In, and is fitted with a shoulder 3|, which bears against the side wall and serves to space and align the roller 2| in the box H3. The friction at this point also serves to prevent undesired rotation of the roller 2| and consequent movement of the web 22, so that the indicia which are aligned with slot l5 will remain in the position to which they are adjusted.
Web 22 may be an endless belt, such as paper, or paper backed with cloth, and is imprinted with the desired indicia 32 to be aligned with slot l6, and data l5 as shown in Figure l. The lower end or bight of web 22 is preferably retained or guided and held taut by an idler roller 33. That roller may conveniently be made of a wooden cy1- inder 34, with two end flanges 35, and is provided with two axial pins 36, which latter may be received in guide slots or channels 31, at the sides of box I0. The web 22 is spaced from the slot M5 by guide bar I8, which thus lies between the front and back turns of the web, and prevents the web from curling or buckling away from the slot, so that its visibility and alignment are not impaired.
In operation, crank 26 is rotated by the operator, thus turning roller 2| and moving the endless web 22 until the desired indicia, as 32 are visible through slot 5 in sheet l4. That data may then be observed in relation to the indicia IS, the operator thus receiving the information desired. To remove the web 22, the sheet M is first removed, as by dropping it downwardly from its normal position in groove l3. Guide bar i8 is lifted from its retaining clip 20, thus permitting the rear turn of the endless web 22 to be withdrawn forwardly from the box l0, together with idler roller 33, after the latters removal from channels 31. Rod 28 is pressed inwardly against spring until it is free from its hole in box H), whereupon the roller 2| and/or web 22 may be withdrawn forwardly from the box IE.
It will be appreciated that with the disclosed elements of a master chart on which are grouped or spaced indicia relating to points of lubrication and the types and grades of lubricants to be used therein, combined with a movable element, such as the endless belt or web, on which are supplementary data as to types, models and years of the various automotive equipment which are to be serviced, with keys or symbols relating to the data on'the master chart, and with means for conveniently aligning and correlating the web with the chart so that the desired data and none other, may be placed in predetermined relationship and be readily observable, and yet shielded and protected from dirt from handling or the weather, this invention represents a considerable improvement and advance over the known art in this field.
Although a specific construction embodying this invention has been described and illustrated, it is to be understood that the invention is not limited to that specific device, and all such modifications and changes as come within the scope of the appended claims are embraced thereby.
