In the drawings, the reference numeral 2 indicates a plate member which is preferably flat, and which may be supported at any desired inclination by' means of an easel structure, indicated at 3, Figure 8. The preferred easel struc- 10 ture does not constitute part of this invention and is fully described in United States Iletters Patent No. 1,883,255 granted October 18; 1932 to Paul O. Unger. The plate member 2 is provided at its edges with downward walls 4 to impart rigidity 15 and strength to the plate member. The walls t also cooperate with the plate member to form a space large enough to receive the easel structure in collapsed condition.
A metal strip 5 and a spacing strip 6 are se- 20 cured to the top wall 4 in any suitable manner such as welding or riveting. The spacing strip G is of less height than the strip 5 so that a recess is formed between the wall 4 and the strip 5 with the strip 6 serving as a base for the recess. The recess is traversed, near one end, by a pin l, and
at a centrally located point by a similar pin 8.
A sliding latch member 9 is secured to the rear surface'of the strip 5 adjacent the end opposite the pin l by means of a pair of studs Hi. The member 9 is provided with a pair of elongated apertures ll through which the studs Hi pass. The latch member 9 is provided with a turned over lip l2 which projects beyond the front surface of the strip 5. The slots H are long enough to permit the latch member 9 to be moved laterally a distance suflicient to move the lip l2 past the edge of the strip 5. The latch Si is provided with a finger piece iii to facilitate sliding the latch.
A sheet retaining bar it is adapted to be secured adjacent the upper edge of the plate memher 2. The sheet retaining bar comprises two metal strips l5 and I6 which are hinged at their meeting edges, as indicated at H. The strip I5 is provided with a downturned flange I8 which is 5 adapted to fit in the recess between the top wall 4 and the strip 5. One end of the flange I8 is provided with a notch 59 adapted to fit around the pin 1. The flange 58 is provided with another notch 29 adapted to fit around the pin 8. The end 5 of the strip l5 opposite the notch 19 is slotted, as indicated at 2 i, to provide clearance for the lip I2, The strip 56 is provided with a downturned flange 22 similar i e flange l8 except that the positions of the notch is and the slot 2i are reversed. Accordingly, the sheet retaining bar may be positioned with either flange I8 or 22 in the recess between the top wall.4 and the strip 5. The latch 9 must be moved outwardly to the position 5 shown in Figure 8 to allow either flange I8 or 22 to be inserted in or removed from the recess. A simple inward sliding movement of the latch 9 causes the lip I2 to move into the slot 2| to provide adequate protection against accidental sepa- 10 ration of the sheet retaining bar from the upper edge of the plate member. The opposite end of the flange is held securely against relative vertical movement by the pin I fitting into the notch I9. Lateral movement of the sheet retaining bar is prevented by the pin 8 fitting into the notch 29.
1 A series of sheet aligning pins 23 is provided on each of the strips I5 and I6. These pins 23 are equally spaced along the strips and are arranged in pairs so that sheets impaled on one series of pins may be turned over and impaled on the other series without any lateral movement. The strip I5 is provided with another series of sheet aligning pins 24 spaced intermediately of the pins 23. Each of the series of pins 24 is re- 25 cessed at its free end, as indicated at 25, to receive the free end of an arched prong member 26. Each of the arched prong members 26 has one end rigidly secured to the strip I6 in any suitable manner.
The latch 9 and associated structure holds one of the flanges I8 or 20 rigidly adjacent the top edge of the plate 2. The other of the flanges I8 or 29 and its strip I5 or I6 is free to move on the hinge I! to separate the end of the arched prong membersfrom the ends of the pins 24. The engagement of the arched prongs 26 and the pins 24 prevents relative movement of the strips I5 and I6 in one direction beyond the point where the strips I5 and I6 are in substantially the same plane. Movement of the strips I 5 and I6 beyond a predetermined point in the opposite direction is prevented by means of a pair of metal strips 2'! and 28 welded to the under side of the strips I5 and I6, respectively, and arranged so that their ends abut each other when the strips have been moved a predetermined distance. Although a single pair of strips 21 and 28 is suflicient for the purpose described, we prefer to use a plurality of pairs of each strip.
When the sheet retaining bar is open a plurality of sheets may be impaled on the pins mounted on the strip I5, or on the arched prongs and pins secured to the strip I6. The strip 21 may be provlded with a depending portion or foot 29 parallel with the flange I8 and spaced therefrom so that the strip 5 is adapted to fit between the flange I8 and the portion 29. Preferably the depending portion 29 projects below the flange I8 so that when the bar I4 is separated from the plate 2 and is placed on a flat surface in open position, the
aligning pins 23 and 24 on the strip I5 project vertically to facilitate the impalement of sheets thereon. When the bar is closed the impaled sheets may be moved from the pins on one strip 5 I5 or I6 to the pins on the other. The arched prongs 26 serve as guide means as well as retaining means for the sheets.
The sheet retaining bar is provided with spring means to, hold the strips I5 and I6 in either 7 closed or open position. In the preferred embodiment (Figure 4), each of the strips I5 and I6 has a portion of its inner edge adjacent the hinge I1 curled back to form a lip 30. A C- shaped compression spring 3| has its ends 32 75 curled to engage the lips 30. As shown in Figure 4, the line between the points of application of force, that is the line between the points of engagement of the ends 32 of the spring with the lips 39, is above the center of the hinge I'I. Accordingly, the force of the spring 3I acts to hold the strips I5 and I6 closed. When the sheet retaining bar is open, the line between the points of application of force lies below the center of the hinge II so that the force of the spring 3| acts to hold the strips I5 and I6 open. The number 10 of springs used may vary with the length of the bar I 4.
In the modified embodiment of the summary bar illustrated in Figures 6 and 7, the only structural difference from the preferred embodiment 15 is in the speciflc form of spring utilized for holding the strips I5 and I6 in either closed or open position. In this embodiment the strips I5 and I6 are provided with registering recesses 33 and a curled lip 34 at the extremity of each recess. A 20 tension spring 35 positioned in each pair of recesses 33 has its opposite ends secured to the lips 34. When the strips I5 and I6 are in closed position, the springs 35 exert force to hold them closed, and when the strips I5 and I6 are 25 in open position the springs 35 exert force to hold them open. Figures 6 and 7 do not show the bar equipped with the extensions 29, but it will be understood that either embodiment of the sheet retaining bar may be built with or with- 30 out the extensions.
A metal strip 31, having outturned flanges 38, is rigidly secured to one side 4 in any suitable manner. The length of the strip 31 exceeds the length of the side wall 4 by a distance sufficient to 35 cause the top flange 38 to lie substantially flush with the free flange of the sheet retaining bar I4 when one of the flanges I8 or 22 is secured adjacent the top of the plate member 2. In the preferred embodiment of the invention a rod 39 of 40 circular cross section is secured between the flanges 38 by means of screws 40. The rod 39 is serated to form a series of teeth 4| extending along the entire length of the rod 39. The teeth 4| are preferably positioned on the side of the rod 39 away from the strip 31. The rod 39 is fixed with respect to the flanges 38 so that the serrated portion of the rod remains on the side away from the strip 31.
A housing 42 is mounted on the rod 39 and 50 is adapted to be moved along the rod by means of mechanism hereinafter described. The housing 42 comprises a top wall 43, and side walls 44,
45, 46 and 41. A metal strip 48, permanently secured to the side wall 44, has one end 49 projecting over the plate member 2 in a plane substan tially parallel thereto. A line guide 50, made of wood or other light, rigid material is permanently secured to the strip 48 by means of rivets 5I or in any other suitable manner. 60
As shown in Figure 9, the line guide 59 is grooved out, as indicated at 52, to reduce the cross sectional area of the line guide along its center portion so that the top and bottom surfaces of the line guide approach parallelism. The grooving out of the underside of the line guide apparently tends to equalize the forces set up in the line guide by atmospheric conditions and thereby reduces the possibility of warpage. The edges of the line guide are beveled, as indicated at 53, to facilitate reading of the data contained on the sheets 54 mounted on the sheet retaining bar. Accordingly it is important that the bar 5| should be prevented from warping. The line guide may be made of metal, but wood is preferred because of its lightness and inexpensiveness.
The. mechanism associated with the housing 42 for moving the housing along the rod 39 includes. a pair of rollers 55 and 56 provided with teeth 51 and 51 adapted to mesh with the teeth 4!. The rollers 55 and 56 are mounted in a channel member 58 by means of shafts 66 and 59, respectively. A pair ofcompression springs 6| urge the channel member 58 towards the rod 39 and maintain the teeth 51 and 51 constantly in mesh with the teeth 4|.
' jects through an aperture 62 in the top wall 43 rod opposite the serrated portion 4|.
are swiveled in the flanges guide is lifted from' and is provided with a knurled knob 63 fixed to its upper end. 7 Rotation of the knurled knob 63' rotates the roller and causes the housing 42 to move along the rod 39. The housing may be pushed up or down the rod if the knob 63 is left free to rotate.
The housing 42 contains a second, pair of rollers 64 and 65 engaging the-periphery of the The rolls 64 and 65 aremounted in a channel member 66 by means of shafts 61 and 68 respectively. The shaft 61 is fixed to the top wall 43 to fix the roller 64 with respect to the housing 42. The
shaft 66 is free of any direct connection with the housing so that the channel member 66 may be moved within the housing, about the shaft 61 as a pivot, to adjust the angularity of the line guide with respect to the plate 2.
The means for moving the channel member 66 includes a threaded stud 69 rigidly secured thereto and having a knurled disc Ill threaded on the stud between the channel member 66 and the side wall 44. The top wall 43 is pro vided with an aperture H through which the periphery of the disc 10 is adapted to extend. The side wall 44 and the strip 48 are apertured to allow the stud 69 to pass therethrough.
If it is desired to raise the free-end of the line guide 50 with respect to the end secured to the metal strip 46, the disc Ill is rotated in a direction to move the stud 69 to the right as viewed in Figures 12 and 14. Since the disc 10 is prevented from moving by the edges of the aperture II, and. the upper end of the channel 66 is prevented from moving by the shaft 61, the lower end of the channel will be moved toward the right around the shaft 61 as a pivot. The apertures l2 and 13 in the walls 46 and 41, through which the rod 39 passes, are sufficiently large to permit the slight lateral movement necessary to allow the housing to tilt and change the angle of the line guide 50 with respect to the plate 2. If the free end of the line guide is to be lowered with respect to the fixed end, it is necessary to rotate the disc 10 in the opposite direction.
In the embodiment of the invention illustrated in Figures .15 and 16 a square rod 14 has been substituted for the circular rod 39. It will be understood that the rod 14 may be of any noncircular cross section. The ends of the rod 14 38, as indicated at 15, so that when the line the plate 2 the rod I4 pivots with the housing 42'.
The driving roller 16 is preferably provided with a friction surface 11 which may be formed of rubber orany other suitable material. Although, the friction surface 11 is shown as being provided with projections 18, the surface may be comparatively smooth. The roller 16 and another roller 19 having a smooth surface are mounted in the housing 42 in the same manner same purpose.
The shaft pro-- 'housing, means to as the rollers 55 and 56 are mounted in the housing 42.
The housing 42' contains a channel member 66' similar to the channel 66 except that it is reversed. Rollers 80 and 8| are mounted in the same manner as rollers 64 and 65 and serve the rollers are provided with fiat peripheries to make better contact with the fiat surface of the rod 14. The means for adjusting the angularity of the line guide is the same as described in connection with Figures 12, 13 and 14.
Although we have described several embodiments of our invention in considerable detail, it will be understood that the description thereof is illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of our invention. Accordingly, we do not desire to be restricted to the exact construction described, except as limited by the appended claims.
