INK-WELL.

SPECIFICATION forming' part of Letters Patent No. 715,984, dated December 16, 1902.

Application filed March 21, 1902- Serial No.99,299. (No model.)

To LZZ whom/ it may concern.-

Be it known that I, WILLIAM S. CLAYPooL, a citizen of the United States, residing at Oagle, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Ink-Wells; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

This invention relates to ink-wells adapted to be applied to school-desks and the like; and the objects of the same are to provide a noiseless ink-well having a positively movable and adjustable cover which may be locked either in closed or open position to form an air-tight dust-proof closing means or obstruct the ready movement of the same when open, alsoto overcome the frolicsome and malicious habits of pupils in trifling with the ink-Wells of their neighbors and avoid dropping foreign matter thereinto, and also to embody simple features of construction which tend to render the ink-well effective to overcome numerous disadvantages heretofore prevalent in this class of devices, and embodying features of adjustment controllable from the under side of a desk or support for conveniently holding the cover against loose movement, either in open or closed position, by means which are not accessible to adjacent scholars or pupils having malicious intent and also remove all exterior obstructions or unsightly projections.

With these and other objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of an ink-well embodying the features of the invention. Fig. 2 is a top plan view of the same, partially broken away, with the cover removed. Fig. 3 is a rear e1evation,par tially broken away. Fig. 4 is a longitudinal Vertical section of the improved ink well shown applied to a desk or similar support.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a ring or annulus having diametrically opposed ears 2, with openings therethrough to receive fasteningscrews by which the entire device may be secured to a desk or othersupport. Extending rearwardly from the ring or annulus 1 are arms 3, which are spaced apart from each other a suitable distance, one of the latter having a leg 4 depending from the inneredge thereof and provided with a pivoted screwcollar 5 at its lower terminal. A cover 6 has a rearward extension '7,with a depending terminal boss 8 movably mounted between the rear terminals of the arms 3, and through the said rear terminals and boss a pivot-pin 9 is passed. The said pin i) is smooth for a greater portion of its length, and particularly that part thereof which passes through the boss 8, and at one end an enlargement 10 is formed and screw-threaded,the free end of the ring being also threaded to engage a correspondingly screw-threaded openingin the arms 3, to thereby secure the pin against accidental disengagement. The smooth structure of the pin 9, engaged by the boss 8, overcomes any tendency of the pin as an entirety working loose by the movement of the cover, and it is obvious that the freedom or ease of movement of the cover in relation to the arms can be controlled by tightening or loosening the said pin. Depending from the extension 7, inside of the arm 3 opposite that from which the leg 4 depends, is a shorter leg 12, to which is pivoted a screw-collar 13, both screw- collars 5 and 13 being free to swing to accommodate the angle of adjustment of the parts, but 0bstructed in having the least vertical movement.

The inner edge of the ring or annulus 1 is formed with a concave seat 14, and therein is fitted the upper convex beaded edge l5 of a glass or other ink well or receptacle 16, the said beaded edge projecting slightly above the plane of the upper surface of the ring` or annulus 1. The body of the ink-Well or other receptacle 16, as well as the legs 14 and 12, project downwardly through a slot or opening formed in the desk-top or other support for the improved device, and engaging the screw- collars 5 and 13 is an adjusting-screw 17, havinga lower milled head 18. The said adjusting-screw is reduced to engage the collar 13, the latter being smaller than the col- IOO lar 5, and in the operation of the improved device the cover 6 is raised and lowered by turning the screw 17 in opposite directions. To render the lid or cover etective in forminga tight joint with the bead 15 when closed, an annular bead 19, having a convex contour, is formed on the under side of said cover to tit into the upper open portion of the well or receptacle 16.

The advantages ofthe construction set forth are numerous, and among many others may be mentioned that the arrangement of the operating parts beneath the top of a desk or other support takes them out of the Way of the unconscious tumbler and obstructs any tendency toward thoughtless operation of the cover, and thus avoids unpleasant noise in a school-room. Moreover, the movement ofthe cover is slow, which is essential to silence in the absence of packing, and no shock or jar can occur when the cover comes into contact With the remaining parts. Furthermore, the screw holds the cover rigid at e'ither point of its transit, and if the cover is left open it cannot be rattled or a plaything be made of it. Frolicsome and malicious pupils are prevented from lifting the covers of the ink-wells of their neighbors and slyly dropping foreign matter therein to in View of the fact that the said cover may be locked when closed, so that it cannot be opened by a pupil who is not in the seat in which the well belongs, and it cannot be done quicklyenough to avoid detection in any case.A By holding the cover down in iirm engagement with the upper end or head of the well or receptacle and forming an air-tight joint also prevents evaporation and thickening of the ink, with a consequent economical use of the latter. A further advantage is the provision in the screw 17 of two threads eugaging the screw- collars 5 and 13, the one being right-hand and the other left-hand, to effectively operate the cover and also provide means which will obstruct any efforts of the pupil to remove the same, as it is obvious that when one thread is screwing out of its collar the other is moving into the collar engaging therewith. It will be seen that a greater or less pitch to the threads of the screw will accelerate or retard the movement. Since every point of the lid describes an arc in its transit, the screw must make a continuous change of direction, and the pivoted screw-collars accom modate this change of direction, with obvious advantages.

It is obvious that changes in the form, size, proportions, dimensions, and minor details may be resorted to Without in the least departing from the spirit of the invention.

Having thus fully described the invention, what is lclaimed as new is- 1. In a device of the class set forth, the combination with an ink-well, ot' a cover pivotally mounted in relation thereto, and screw mechanism for gradually opening and closing the cover and holding the latter against loose movement in either of its adjusted positions.

2. In a device of the class set forth, the combination with an ink-well*` ot' a pivotallymounted cover having screw mechanism connected thereto for holding the same against loose movement when open or closed.

3. In a device of the class set forth, the combination with an ink-well, of a cover having depending screw mechanism adapted to be concealed within the support for the ink-Well for gradually opening and closing the cover and holding the latter against loose movement in either of its adjusted positions.

4. In a device of the class set forth, the combination with an ink-well, of a pivotallymounted cover, and a depending screw device having a movable connection with a part of the cover for gradually opening and closing the latter and holding it against loose movenient when in either of its adjusted positions.

In testimony Whereot` I alix my signature in presence of two witnesses.
