Referring to FIGURES l, 2 and 3, reference numeral It? designates generally a casing or housing having parallel side walls 12 and 13 integral therewith, and a large bottom opening 11 bet-ween the lower edges of said side walls.
Numeral 15 designates an upper inclined end wall whose'rearmost edge portion is bent angularly downwardly to form a depending inwardly extending hook 37.
Numeral 14- designates a pair of inwardly extending flanges which are formed by inwardly bending at right angles the inclined rear portions of the side walls 12 and 13, one of said flanges being illustrated in FIGURE 3.
The upper portions of said flange 14 are connected to the hook portion 37 of the upper rear wall 15.
Numeral 16 designates an inclined forward panel or wall which has a pair of elongated longitudinally extendring edge recesses 18 opening in opposite directions, and has a relative large transverse slot or opening 19 formed a short distance below the uppermost corner of said hous- Said housing and said walls are preferably made of relatively thin metal, although the same may be made of plastic or equivalent material. Side walls 11 and 12 have their lower edges bent outwardly to form integral angular apertured flanges 13a and 12a, as shown in FIG- URE I. Said base flanges 12a and 13a have pads 52 secured by screws to the apertured portions thereof, as illustrated in FIGURE 3. The window opening or slot 19 extends from the forward edge of side wall 12 to the forward edge of the opposite side wall 13, as illustrated.
The upper edge of front panel has an outwardly offset angular flange 20. A separate metal plate 26a is secured by welding to the inside face of the front panel 16, to form a transverse upwardly opening slot, with the flange 20, which provides a slot and recess seat for the lower edge of a transparent panel or window 21, as illustrated in FIGURES 3 and 6.
Numeral 21 designates a flat relatively thin transparent panel or window, preferably of rectangular form and preferably made of clear plastic or glass and which has formed therein a relatively deep central recess or slot 22 opening on the upper edge portion thereof, as illustrated in FIGURES 1 and 2.
- Said window or panel 21 has a lower downwardly opening relatively large recess 23 at its normally right hand end portion and preferably of substantially rectangular form, as illustrated in FIGURES l and 2.
Said recess 23 may vary in size and preferably extends about one-fourth the distance inward from the right edge of window 21, and is sufiicient to permit a user to write usual answers through it on the uppermost paper sheet supported below the same.
As shown in cross section in FIGURES 3, 5 and 6, a transverse metal supporting plate 28 has its opposite angularly bent ends 23 secured by welding to the opposite vertical side walls 12 and 13 of the housing It The downwardly extending longitudinal edge portion of said plate 28 is bent downward to form a deflector and guide flange 30, as shown in FIGURE 3, and which flange is engaged by the upper edges of the sheets when same are pushed upward to guide the same. As shown in FIGURE 5, plate 28 has a pair of right angled brackets 31 secured to its opposite ends with the short legs of said brackets extending upwardly so that the same engage and support the window 21 a short distance above the uppermost sheet 54 of a group of sheets, one of which rackets 31 is shown in FIGURE 5.
Said transparent window panels 21 are accordingly removably mounted, and difierent panels having difierent sizes of writing recesses 23 may be selectively mounted in said position.
As illustrated in FIGURE 6, a flexible leaf spring 32 has one apertured end secured to window panel 21 by a rivet 33 so that it extends upward and inwardly so that its integral free end will slidably engage each uppermost sheet to permit each such sheet to be advanced and to prevent each uppermost sheet from being retracted and moved backward by students after they have seen the printed answer on the sheet. This prevents the possibility of the student changing his answer after the sheet has been advanced to positions wherein the written answer is obstructed though visible through the right end portion of the window panel 21.
I provide mews for adjusting the tension of said spring 32 to vary its pressure against the paper sheets and this comprises an adjusting screw 34 which is threaded in the window panel in a position above the free end of the spring 32, as illustrated in FIGURE 6. It will be noted that the inner projecting end of said screw 34 bears against the intermediate portion of said spring 32.
Forward upper inclined wall portion 35 is parallel with front panel 16 and is preferably integral with and angular with the downwardly inclined upper end wall 15. End wall 15 is bent angularly downwardly as at 36 and its end is doubled back to form an inwardly opening hook 37 providing an upwardly opening slot or recess.
The guide means which I provide for guiding and stacking the paper sheets include a substantially semicylindrical and arcuate baifle or member 38 which has its upper edge preferably integral with the upper wall portion 35 and which has its inner edge portion bent angularly to form a mounting and anchoring flange 39, as illustrated in FIGURE 3. Mounting flange 39 is seated and held in the hook 37 as illustrated in FIGURE 3.
I provide removably mounted means for receiving and holding the advantaged sheets within the housing which permits selective removal of the sheets and which may be selectively locked to prevent such removal. This comprises an elongated metal supporting and stacking panel tray or holder 4-9 which has one end edge angularly bent to form an integral flange 4-1 which is loosely seated in hook 37 as shown in FIGURE 3.
The lower portion 42 of stacking panel or tray 40 is bent angularly at an obtuse angle and its extreme edge is doubled back to form a reinforcing edge 43. Holder portion 42 has a central slot 44 formed therein which is normally hooked over an apertured car 45 formed on the lower end of the inclined inner paper supporting panel 46 which is parallel to inclined front panel 16 and spaced inwardly therefrom. Between the lower end edge of front wall 16 and the lower end edge of support panel 46 is a paper loading slot or opening 43 which is preferably about one-half inch wide and extends from one side wall 12 to the other side wall 13 and through which a stack of printed lesson sheets 59 are inserted into the housing when the flexible panel 42 is disengaged and removed outward from the car 45. It is to be understood that holder panel 42 and the paper supporting panel 4% are of thin sheet metal and suhiciently flexible to permit manual outward bending of panel 42 to remove its lower edge portion from the car 45 and permit said paper support panel 40 and panel 42 to be swung or pivoted downwardly and in a counterclockwise direction and through the large opening in the bottom of the housing to thereby permit manual access and removal of the stacked paper sheets on stacking panel 4%. The integral hook 41 of stacking panel 4% is suiiiciently loose in the hook 37 to permit such pivoting movement of said panel 40;
The projecting car 45 is apertured as indicated in FIG- URE 1 so that a padlock may be mounted through said aperture when the stacking panel is in closed position, to thereby selectively restrict access to the papers within the machine only to teachers and authorized persons.
A metal angularly bent bracket 53 has its lower bent portion secured by welding to the inner face of the panel portion 42, as illustrated in FIGURE 3, and this forms a stop means which stops the downward sliding of the sheets when they fall on the support paneled and causes them to be evenly stacked in upside down positions.
It is to be understood that after the user writes on the writing areas 52 of the uppermost sheet his answers to the questions visible through the left hand portion of the window, the user will then advance the sheet a short distance. For example, by pushing the sheet upward and forward by inserting his pencil through the central slot 22 and pushing upwardly one length of the central slot this will result in the printed correct answers on the sheet (which have been obstructed by the masking member 54) to be made visible through the window portion 55 immediately above the masking member 54 Thereupon the written answer has been positioned under the portion of the window designated as 53 in FIG- URE 2 and the user is prevented from retracting or moving downwardly the said advanced sheet by the engagement of the leaf spring against said sheet as described.
The user will then advance the sheet upwardly by similar action to present to View the next question printed on the sheet and he can thereupon write his answer on the writing area of the paper within the writing recess 23.
The respective answers may accordingly be recorded to the respective questions on the sheet as described, and when the last answer of the last question on the sheet has been recorded the sheet will be in the bent arcuate position and partially over the upper portion of the stacking panel 40 on which it will drop by gravity into the inverted position to be stacked upon said supporting panel 40 in the manner illustrated. This dropping of the re-' corded sheet occurs as soon as the sheet has been advanced so that its lower edge passes and is disengaged by the spring 32.
When a teacher desires to check and grade the papers of students, the pivoted closure panel is opened by disengaging its lower slotted edge from the car 45 and removing the stacked papers from within the machine. Where desired, the machine may be locked by the teacher after loading and such lock may later be released and removed only by the teachers when desired.
My aforesaid teaching machine provides great advantages in the saving of time by teachers and in permitting students to take and record various tests without assistance or instruction from teaching staffs and further provides an advantageous device for self-teaching and in acquisition of self-reliance.
