E. P. TRUESDALE FOUNTAIN INKWELL Filed March 16; 1936 A w Z E- P. Traesdaze.

Patented July 6, 1937 UNITED STATES- PATENT OFFICE 8 Claims.

This invention relates to an ink well of the fountain type and one object of the invention is to provide the ink well with an improved type of ink receiving well or pocket into which ink flows from a reservoir formed by the body of the ink well, the ink receiving pocket being provided with an entrance so constructed that while the pen may be freely inserted and removed therefrom, the pen holder will be limited in its inward movement and prevented from being covered with ink by being inserted too far into the entrance of the ink receiving pocket. I

Another object of the invention is to so construct the entrance to the ink receiving pocket that it will be located above the same when the ink well is in an upright position and also above the ink receiving chamber or reservoir when the ink well is bent upon its back in position for filling and thus permits the inkwell to be easily filled through the entrance neck of the pocket.

Another object of theinvention is the provision of an improved closure for the entrance neck, the closure being pivotally mounted so that it will normally remain in position to close the entrance neck but permit it to be swung inwardly by pressure applied to its lower end portion when a pen is thrust into the entrance.

Another object of the invention is to so construct and mount the closure that when the ink well is in an upright position outward movement of the lower end of the closure will be limited, whereas when the ink well is turned to an inverted position, this end portion of the closure may be easily swung outwardly to such an extent that the closure will slide through slots in which it is pivotally mounted and out of the entrance neck, thus leaving the entrance neck unobstructed and permitting a fresh supply of ink to be freely poured through the neck and into the reservoir chamber.

Another object of the invention is to provide an ink well of the fountain type wherein an air passage is provided vertically in the reservoir chamber over the inner end portion of the ink receiving well or pocket and thus permit air to pass upwardly into the upper portion of the reservoir when the level of ink in the pocket has been reduced by use or evaporation to such a point that a replenishing of the ink in the pocket is necessary.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a sectional view taken vertically through the improved ink well.

Figure 2 is a view showing the improved ink well in front elevation.

Figure 3 is a sectional view taken vertically through the ink well along the line 33 of Figure 1.

Figure 4 is a horizontal sectional view taken along the line 4-4 of Figure 1.

Figure 5 is a fragmentary view showing the ink well in an inverted position to permit removal of the closure.

Figure 6 is a perspective view of the closure.

This improved ink well may be formed of metal, glass or any other desired material and has a body I which is preferably rectangular when viewed in vertical or horizontal cross section but maybe of any desired shape and also of any dimensions according to the quantity of ink which it is desired to have the ink receiving chamber or reservoir 2 hold. The bottom 3 of the reservoir chamber 2 is spaced upwardly above the lower end of the body I, thus providing space in the lower portion of the body to receive the well or pocket 4 into which a quantity of ink flows from the reservoir chamber. By referring to Figure 1 it will be seen that thepocket 4 exstood that if so desired the neck 5 and'its jacket 6 may be formed as an integral structure instead of forming the jacket separate from the neck and then securing it about the neck. By having the neck threaded, a cap 1 may be screwed tightly thereon to prevent evaporation when the I ink well'is not in use. The mouth 8 of the jacket which projects outwardly beyond the neck 5' is flared, as clearly shown in Figures 1 and 4, so that ink may be guided'into the neck when filling the ink well. This also provides a bordering surface about the outer end of the neck constituting a good abutment to engage the end of'a pen holder and limiting movement of the pen holder and afpen inwardly through the neck, as indicated by dottedlines in Figure 1. Achanneled strip 9 extends vertically in the'reservoir chamber 2 against the front wall of the body over the inner end portion of the pocket 4 and serves as an air passage through which air may travel upwardly from the neck and pocket into the upper end of the reservoir chamber so that ink may flow from the reservoir chamber intothe pocket to replenish the supply therein when necessary without bubbling which would be liable to cause inkto have surging motion in the pocket and spill outwardly through the neck. It should also be noted that this channeled strip or air conduit 9 serves to block the upper end of a major portion of the pocket within the body and thus prevent excessive flow of ink from the reservoir into the pocket.

In order to normally close the neck and prevent entrance of dust into the pocket and also prevent excessive evaporation of ink in the pocket when the cap I is removed, there has been provided a closure ID having the form of a semi-circular block of metal which is of such Width that it fits snugly into the neck between the flat side walls thereof. A face plate H is fixed to the flat front or outer face of the closure block and is of such length that one end portion of the plate projects from the block to provide a lip l2 adapted to engage the upper end portion of the sloping front wall I3 of the pocket 4 and limit outward movement of the lower end of the closure when the ink well is in the upright position shown in Figure 1. By referring to this figure it will be readily seen that while the lower end portion of the closure block may be easily swung inwardly by pressure of a pen point applied thereto, it cannot move outwardly beyond the position shown in full lines in this figure. Therefore, the ink in the pocket will be shielded to prevent dust accumulating in the ink in the pocket. Pivot pins l4 extend from opposite side edges of the face plate ll midway ends of the front face of the closure block and these pivot pins are engaged in seats I5 which are in the form of grooves formed in opposite side walls of the neck with their outer end portions extending across the mouth of the jacket 6. These grooves extend inwardly at a downward incline with their inner ends terminating opposite each other midway the depth of the neck and as the inner ends of the grooves are rounded, as shown clearly in Figure 5, the pivot pins can turn freely in the grooves and thus permit the closure block to be easily moved inwardly when a pen is inserted into the pocket 4 and then return to the closed position as the pen is withdrawn. Attention is called to the fact that ends of the block are out of contact with the upper wall of the neck and the sloping front wall of the pocket but that the lip [2 projects from the closure block to such an extent that when the ink well is in the upright position this tongue or lip may engage the sloping front wall of the pocket and limit outward movement of the lower portion of the closure beyond the position shown in full lines in Figure 1. When, however, it is desired to remove the closure block and thus permit the reservoir chamber to be refilled with ink, the ink well may be disposed in an inverted position, as shown in Figure 5, and the pivot pins may then slide along the grooves l5 to such a position that the arcuate face of the closure block will rest upon the wall of the neck and the distance between the pivot pins and the sloping wall l3 of the ink receiving pocket will be greater than the distance between the pivot pins and the outer end of the lip or tongue l2. Therefore, when pressure is applied to the outwardly projecting portion of the closure block by a pen, pencil, or other implement indicated by dotted lines in Figure 5, the closure block may be completely rotated in the neck and as the lip l2 moves outwardly beyond the outer end of the sloping wall 13 of the neck, the pivot pins will slide downwardly through the grooves l5 and the closure block passed outwardly from the neck.

The ink well may then be set upon its rear wall with its jacketed neck extending upwardly and a fresh supply of ink poured through the neck to fill the reservoir chamber, after which the closure block may be replaced and the ink well tion, the level of the ink will finally reach a point in spaced relation to the lower end of the air passage and air may then pass upwardly through this passage'into the upper end of the reservoir and a fresh supply of ink will flow from the reservoir into the pocket until the lower end of the air passage is again closed. By replacing thecap 1 when the ink well is not in use excessive evaporation of ink in the pocket will be prevented and also dust prevented from accumulating upon the outer face of the closure and the outer end portion of the neck.
